[0001] The application claims priority to U.S. Provisional Patent Application No. 62/755,965, filed November 5, 2018, entitled "Cartridges For Vaporizer Devices", the disclosure of which is incorporated herein by reference in its entirety to the extent permitted.

Field of technology to which the invention relates

[0002] The subject matter of the invention described herein relates to vaporizer devices including vaporizer cartridges.

State of the art

[0003] Evaporative devices, which may also be referred to as vaporizers, electronic vaporizers, or electroevaporative devices, can be used to deliver an aerosol (e.g., a vapor-phase and/or condensed-phase substance suspended in a stationary or moving mass of air or some other gaseous carrier ), containing one or more active ingredients, through inhalation of the aerosol by the user of the vaporization device. For example, electronic nicotine delivery systems (ENDS) include a class of vaporizer devices that are battery-powered and that can be used to simulate the sensation of smoking but without burning tobacco or other substances. Vaporizer devices are becoming increasingly popular for both prescriptive medical use, drug delivery, and the consumption of tobacco, nicotine, and other herbal substances. Evaporative devices may be portable, self-contained, and/or user-friendly.

Such evaporation devices are known, for example, from RU 2620951 C1, KZ 31968 B, RU 2606326 C2, US 20180177240 A1, US 20140069424 A1, US 20180160735 A1.

[0004] When using a vaporizer device, the user inhales an aerosol, colloquially referred to as “vapor,” which may be generated by a heating element that vaporizes (e.g., causes a liquid or solid to at least partially enter a gaseous phase) the vaporized substance , which may be a liquid, solution, solid, paste, wax, and/or any other form compatible for use with the particular vaporizer device. The vaporizable substance used with the vaporizer device may be provided in a cartridge, for example, a detachable portion of the vaporizer device that contains the vaporizable substance, which includes an outlet (eg, a mouthpiece) for inhalation of the aerosol by the user.

[0005] To receive the inhalable aerosol generated by the vaporizer device, the user may, in some examples, activate the vaporizer device by taking a puff, pressing a button, and/or some other approach. A puff, as used herein, may refer to the user inhaling in a manner that forces a volume of air to be drawn into the vaporizer device such that an inhaled aerosol is formed by the combination of the vaporized vaporized substance with the volume of air.

[0006] The approach by which a vaporizer device generates a respirable aerosol from a vaporized substance involves heating the vaporized substance in a vaporization chamber (eg, a heater chamber) to cause the vaporized substance to convert into a gaseous (or vapor) phase. A vapor chamber may refer to an area or volume in a vaporizer device in which a heat source (e.g., a conductive, convective, and/or radiant heat source) causes the vaporizer to be heated to create a mixture of air and vaporizer to form vapor for inhalation of the vaporizer by a user evaporation device.

[0007] Vaporizer devices may be controlled by one or more controllers, electronic circuits (eg, sensors, heating elements), and/or the like. on the evaporation device. Evaporative devices can also communicate wirelessly with an external controller, such as a computing device such as a smartphone).

[0008] In some implementations, vaporizable material may be drawn from the reservoir and into the vaporization chamber through an absorbent element (eg, a wick). The drawing of vaporizable material into the flash chamber may be at least partially due to capillary action provided by the absorbent element, where the absorbent element pulls vaporizable substance along the absorbent element towards the flash chamber. However, when the evaporated substance is drawn from the reservoir, the pressure inside the reservoir is reduced, thereby creating a vacuum and acting against capillary action. This may reduce the effectiveness of the wicking element to draw vaporizer into the vapor chamber, thereby reducing the effectiveness of the vaporizer device to vaporize a desired volume of vaporizer, such as when a user takes a puff on the vaporizer device. In addition, the vacuum created in the reservoir may ultimately result in an inability to draw all of the vaporized substance into the flash chamber, thereby wasting the vaporized substance. As such, improved vaporizer devices and/or vaporizer cartridges that improve or overcome these problems would be desirable.

Detailed Description of the Invention

[0033] Implementations of the current subject matter include methods, devices, articles of manufacture and systems related to vaporizing one or more substances for inhalation by a user. Exemplary implementations include evaporative devices and systems including evaporative devices. The term "vaporizer device," when used in the following description and claims, refers to any of a stand-alone device, a device that includes two or more separable parts (for example, a vaporizer body that includes a battery and other hardware, and a cartridge that includes a vaporizable substance), and/or the like. "Evaporation system" as used herein may include one or more components, such as an evaporation device. Examples of vaporizer devices consistent with implementations of the current subject matter include electronic vaporizers, electronic nicotine delivery systems (ENDS), and/or the like. In general, such vaporizer devices are pocket-sized devices that heat (eg, by convection, current, radiation, and/or some combination thereof) the vaporized substance to provide an inhalable dose of the substance.

[0034] The vaporizable substance used in conjunction with the vaporizer device may be provided in a cartridge (e.g., the part of the vaporizer device that contains the vaporizable substance in a reservoir or other container), which may be refillable when empty, or disposable so that a new a cartridge containing additional vaporizer of the same or a different type may be used). The vaporizer device may be a cartridge-based vaporizer device, a cartridge-less vaporizer device, or a reusable vaporizer device adapted for use with or without a cartridge. For example, the vaporizer device may include a heating chamber (e.g., a heat chamber or other area in which a substance is heated by a heating element) configured to receive vaporizable substance directly within the heating chamber, and/or a reservoir or the like. to contain the evaporated substance.

[0035] In some implementations, the vaporizer device may be configured for use with a liquid vaporizable substance (e.g., a solution of a carrier in which the active and/or inactive ingredient(s) are suspended or held in solution, or a liquid form of the vaporizable substance itself) . The liquid vaporizable substance can be adjusted to completely vaporize. Alternatively, at least a portion of the liquid vaporized material may remain after all of the respirable material has been vaporized.

[0036] Referring to the block diagram in FIG. 1A, vaporizer device 100 may include a power source 112 (e.g., a battery, which may be a rechargeable battery), and a controller 104 (e.g., a processor, circuitry, etc. configured to perform logic) for controlling the delivery of heat to the atomizer 141 to cause the vaporized substance 102 to be converted from a condensed form (such as a liquid, solution, suspension, a portion of at least partially unprocessed plant matter, etc.) into a gaseous phase. The controller 104 may be part of one or more printed circuit boards (PCBs) consistent with some implementations of the current subject matter.

[0037] After vaporizer 102 is converted to the gaseous phase, at least some of the vaporizer 102 in the gaseous phase may condense into particulate form in at least partial local equilibrium with the gaseous phase as part of an aerosol, which may form some the portion or all of the inhalable dose delivered by the vaporizer device 100 during a user puff or draw on the vaporizer device 100. It should be understood that the interaction between the gaseous and condensed phases in the aerosol generated by the vaporizer device 100 can be complex and dynamic due to such factors such as ambient temperature, relative humidity, chemical composition, flow conditions in air flow paths (both within the evaporative device and in the respiratory tract of a person or other mammal), and/or mixing of the vaporized substance 102 in the gaseous phase or aerosol phase with other air flows that may influence one or more physical parameters of the aerosol. In some vaporizer devices, and in particular for vaporizer devices configured to deliver volatile vaporizable substances, the inhaled dose may exist predominantly in the gaseous phase (eg, the formation of condensed phase particles may be very limited).

[0038] The atomizer 141 in the vaporizer device 100 may be configured to vaporize the vaporizable substance 102. The vaporizable substance 102 may be liquid. Examples of vaporizable substance 102 include pure liquids, suspensions, solutions, mixtures and/or the like. The atomizer 141 may include an absorbent element (ie, a wick) configured to transfer a volume of vaporized substance 102 to a portion of the atomizer 141 that includes a heating element (not shown in FIG. 1A).

[0039] For example, the absorbent member may be configured to draw vaporizable substance 102 from a reservoir 140 configured to contain vaporizable substance 102, so that vaporizable substance 102 can be vaporized by heat supplied from the heating element. The wicking element may also optionally allow air to enter the reservoir 140 and replace the volume of vaporizer 102 removed. In some implementations of the current subject matter, capillary action may draw the vaporizer 102 into the wick for vaporization via the heating element, and air may be returned to the reservoir 140 through the wick to at least partially equalize the pressure in the reservoir 140. Other methods of allowing air to return back to the reservoir 140 to equalize the pressure are also within the scope of the present invention.

[0040] When used herein, the terms “wick” or “absorbent element” include any material adapted to cause fluid movement through capillary pressure.

[0041] The heating element may include one or more of a conductive heater, a radiant heater, and/or a convection heater. One type of heating element is a resistive heating element, which may include a material (such as a metal or alloy, such as a nickel-chromium alloy, or a non-metallic resistor) configured to dissipate electrical power in the form of heat when electric current is passed through one or more resistive heating element segments. In some implementations of the current subject matter, the atomizer 141 may include a heating element that includes a resistive coil or other heating element wrapped around, positioned within, embedded in a 3D mold, pressed into thermal contact with, or otherwise configured to deliver heat to the absorbent member to cause the vaporizable substance 102 to be drawn from the reservoir 140 by the absorbent member to be vaporized for subsequent inhalation by the user in a gaseous and/or condensed (eg, aerosol particles or droplets) phase. Other absorbent elements, heating elements, and/or atomizer assembly configurations are also possible.

[0042] The heating element may be activated in association with a user's puff (i.e., drawing, inhaling, etc.) on the mouthpiece 130 of the vaporizer device 100 to cause air to flow from the air inlet, along the air flow path, which passes through the atomizer 141 (ie, the absorbent element and the heating element). Optionally, air may flow from the air inlet through one or more condensation areas or chambers, to the air outlet in the mouthpiece 130. The incoming air moving along the air flow path moves over or through the atomizer 141, where the vaporized substance 102 is in gaseous form is carried into the air. The heating element may be activated through a controller 104, which may optionally be part of the vaporizer body 110 as discussed herein, causing current to flow from the power supply 112 through circuitry including a resistive heating element, which is optionally part of the vaporizer cartridge 120. as discussed in this document. As noted herein, entrained vaporizer 102 in gaseous form may condense as it passes through the remainder of the airflow path such that an inhaled dose of vaporizer 102 in aerosol form can be delivered from an air outlet (e.g., mouthpiece 130). for inhalation by the user.

[0043] Activation of the heating element may be caused by automatic puff detection based on one or more signals generated by one or more sensors 113. Sensor 113 and signals generated by sensor 113 may include one or more of the following: a pressure sensor or sensors, located to detect pressure along the air flow path relative to ambient pressure (or optionally to measure changes in absolute pressure), a motion sensor or sensors (e.g., an accelerometer) of the vaporizer device 100, a flow sensor or sensors of the vaporizer device 100, a capacitive lip sensor of the vaporizer device 100, detecting user interaction with vaporizer device 100 through one or more input devices 116 (e.g., buttons or other tactile control devices of vaporizer device 100), receiving signals from a computing device in communication with vaporizer device 100, and/or through other approaches to determine that tightening is occurring or is about to happen.

[0044] As discussed herein, vaporizer device 100, consistent with implementations of the current subject matter, may be configured to communicate (such as, for example, wirelessly or via a wired connection) with a computing device (or optionally two or more devices) in communication with the evaporative device 100. To do this, the controller 104 may include communication hardware 105. The controller 104 may also include a memory 108. The communications hardware 105 may include firmware and/or may be controlled by software to implement one or more cryptographic protocols for communications.

[0045] The computing device may be a component of a vaporizer system that also includes vaporizer device 100, and may include its own communications hardware that can establish a wireless communication channel with communication hardware 105 of vaporizer device 100. For example, the computing device the device used as part of the evaporative system may include a general purpose computing device (such as a smartphone, tablet, personal computer, some other wearable device such as a smart watch, or the like) that runs software to create a user interface for allowing a user to interact with the vaporizer device 100. In other implementations of the current subject matter, such a device used as part of the vaporizer system may be a specialized piece of hardware, such as a remote control or other wireless or wired device having one or more physical or software (i.e., configured on a screen or other display device and selected through user interaction with a touch-sensitive screen or some other input device such as a mouse, pointer, trackball, cursor buttons, or the like) interface controls. The evaporative device 100 may also include one or more output devices 117 or devices for providing information to the user. For example, output devices 117 may include one or more light-emitting diodes (LEDs) configured to provide feedback to a user based on the status and/or operating mode of vaporizer device 100.

[0046] In an example in which a computing device provides signals related to activating a resistive heating element, or in other examples for connecting the computing device to vaporizer device 100 to implement various controls or other functions, the computing device executes one or more sets of computer instructions, to provide the user interface and underlying data processing. In one example, the computing device's detection of user interaction with one or more user interface elements may cause the computing device to signal the vaporizer device 100 to activate the heating element to reach an operating temperature to create an inhalable dose of vapor/aerosol. Other functions of the vaporizer device 100 may be controlled through user interaction with a user interface on a computing device in communication with the vaporizer device 100.

[0047] The temperature of the resistive heating element of the electronic vaporizer device 100 may depend on a variety of factors, including the amount of electrical power delivered to the resistive heating element and/or the duty cycle at which electrical power is applied, conductive heat transfer to other parts of the electronic vaporizer device 100, and /or to the environment, latent heat losses due to evaporation of vaporized substance 102 from the absorbent element and/or atomizer 141 as a whole, and convection heat losses due to air flow (i.e., air moving through the heating element or atomizer 141 as a whole, when the user takes a puff on the vaporizer device 100). As noted herein, in order to reliably activate the heating element or heat the heating element to a desired temperature, vaporizer device 100 may, in some implementations of the current subject matter, use signals from sensor 113 (e.g., a pressure sensor) to determine when the user inhales. Sensor 113 may be placed in the airflow path and/or may be connected (for example, through a passage or other path) to the airflow path comprising an inlet for air to enter the vaporizer device 100 and an outlet through which the user inhales the resulting airflow. resulting in vapor and/or aerosol such that sensor 113 senses changes (eg, pressure changes) simultaneously with air passing through evaporator device 100 from the air inlet to the air outlet. In some implementations of the current subject matter, the heating element may be activated in association with a user's puff, for example, through automatic puff detection, or through sensor 113 detecting a change (such as a change in pressure) in the air flow path.

[0048] Sensor 113 may be located on or coupled to (i.e., electrically or electronically connected, either physically or via a wireless connection) to controller 104 (eg, a printed circuit board assembly or other type of circuit board). To perform measurements accurately and maintain the durability of the evaporator device 100, it may be useful to provide a seal 127 that is resilient enough to separate the air flow path from other parts of the evaporator device 100. The seal 127, which may be a gasket, may be configured to at least , partially surround the sensor 113 so that the connections of the sensor 113 to the internal circuitry of the evaporator device 100 are separated from the portion of the sensor 113 exposed to the air flow path. In an example of a cartridge-based vaporizer device, seal 127 may also separate portions of one or more electrical connections between vaporizer housing 110 and vaporizer cartridge 120. Such seal arrangements 127 in evaporator device 100 may be useful in mitigating potentially damaging effects on evaporator components resulting from interactions with environmental factors such as vapor or liquid water, other fluids such as evaporator material 102, etc. .d., and/or reduce the loss of air from the designed air flow path in the evaporator device 100. Unwanted air, liquid or other fluid passing through and/or contacting the circuits of the evaporator device 100 may cause various undesirable effects, such as changed pressure readings, and/or may result in the formation of undesirable matter, such as moisture, excess vaporizer 102, etc., in parts of the vaporizer device 100, where they may result in a poor pressure signal, degradation of the sensor 113 or other components and/or shorter life of the vaporizer device 100. Leaks in the seal 127 may also result in the user inhaling air that has passed through parts of the vaporizer device 100 containing, or constructed from, materials that may be undesirable for inhalation.

[0049] In some implementations, the vaporizer body 110 includes a controller 104, a power source 112 (such as a battery), one or more sensors 113, charging contacts (such as contacts for charging the power supply 112), a seal 127, and a cartridge holder 118 , configured to receive an evaporator cartridge 120 for connection to the evaporator main body 110 through one or more of a plurality of connection structures. In some examples, the vaporizer cartridge 120 includes a reservoir 140 for containing the vaporizable substance 102 and the mouthpiece 130 has an aerosol outlet for delivering an inhaled dose to the user. The vaporizer cartridge 120 may include an atomizer 141 having a wicking element and a heating element. Alternatively, one or both of the absorbent element and the heating element may be part of the evaporator body 110. In an implementation in which any part of the atomizer 141 (i.e., heating element and/or wicking element) is part of the main vaporizer body 110, the vaporizer device 100 may be configured to supply vaporizable substance 102 from a reservoir 140 in the vaporizer cartridge 120 to the part (wells) of the atomizer 141 included in the main body 110 of the evaporator.

[0050] In an embodiment of the vaporizer device 100 in which the power source 112 is part of the vaporizer body 110 and the heating element is housed in the vaporizer cartridge 120 and configured to be coupled to the vaporizer body 110, the vaporizer device 100 may include electrical components connections (eg, circuit termination means) to complete a circuit that includes a controller 104 (eg, a printed circuit board, microcontroller, or the like), a power supply 112, and a heating element (eg, a heating element in atomizer 141). These parts may include one or more contacts (referred to herein as cartridge contacts 124a and 124b) on the bottom surface of the vaporizer cartridge 120 and at least two contacts (referred to herein as holder contacts 125a and 125b) located adjacent base of the cartridge holder 118 of the vaporizer device 100 such that the cartridge contacts 124a and 124b and the holder contacts 125a and 125b make electrical connections when the vaporizer cartridge 120 is inserted into and connected to the cartridge holder 118. The circuit completed by these electrical connections may provide the ability to supply electrical current to the heating element and may further be used for additional functions such as measuring the resistance of the heating element for use in determining and/or controlling the temperature of the heating element based on the thermal coefficient of resistivity of the heating element. element.

[0051] In some implementations of the current subject matter, cartridge contacts 124a and 124b and holder contacts 125a and 125b may be configured for electrical connection in one or another of at least two orientations. In other words, one or more circuits required to operate the vaporizer device 100 may be completed by inserting the vaporizer cartridge 120 into the cartridge holder 118 in a first rotational orientation (about the axis along which the vaporizer cartridge 120 is inserted into the cartridge holder 118 of the vaporizer body 110) , so that the cartridge contact 124a is electrically connected to the holder contact 125a, and the cartridge contact 124b is electrically connected to the holder contact 125b. In addition, one or more circuits required to operate the vaporizer device 100 may be completed by inserting the vaporizer cartridge 120 into the cartridge holder 118 in a second rotation orientation such that cartridge contact 124a is electrically coupled to holder contact 125b and cartridge contact 124b is electrically coupled to contact 125a of the holder.

[0052] For example, the vaporizer cartridge 120, or at least the insertion end 122 of the vaporizer cartridge 120, may be symmetrical when rotating 180° about the axis along which the vaporizer cartridge 120 is inserted into the cartridge holder 118. In such a configuration, the circuitry of the vaporizer device 100 can maintain identical operation no matter what symmetrical orientation of the vaporizer cartridge 120 occurs.

[0053] In one example of an attachment structure for attaching a vaporizer cartridge 120 to a vaporizer body 110, the vaporizer body 110 includes one or more fasteners (e.g., pits, projections, etc.) projecting inwardly from an interior surface of the cartridge holder 118 , an additional material (such as metal, plastic, etc.) formed to include a portion projecting into the interior of the cartridge holder 118, and/or the like. One or more outer surfaces of the vaporizer cartridge 120 may include corresponding recesses (not shown in FIG. 1A) that may fit and/or otherwise snap over such latches or projections when the vaporizer cartridge 120 is inserted into the cartridge holder 118 of the main body 110 evaporator. When the vaporizer cartridge 120 and the vaporizer body 110 are connected (e.g., by inserting the vaporizer cartridge 120 into the vaporizer holder 118 of the vaporizer body 110), the latches or projections of the vaporizer body 110 may be mounted within and/or otherwise held within the recesses of the vaporizer cartridge 120 to hold the vaporizer cartridge 120 in place when assembled. Such an assembly may provide sufficient support to hold the vaporizer cartridge 120 in place to ensure good contact between the cartridge contacts 124a and 124b and the holder contacts 125a and 125b, while allowing the vaporizer cartridge 120 to be removed from the vaporizer body 110 when the user pulls with reasonable force on the vaporizer cartridge 120 to disengage the vaporizer cartridge 120 from the cartridge holder 118 .

[0054] In some implementations, the vaporizer cartridge 120, or at least the insertion end 122 of the vaporizer cartridge 120 configured to be inserted into the cartridge holder 118, may have a non-circular cross-section transverse to the axis along which the vaporizer cartridge 120 is inserted into the cartridge holder 118 . For example, the non-circular cross-section may be approximately rectangular, approximately elliptical (i.e., approximately oval in shape), non-rectangular but with two sets of parallel or approximately parallel opposite sides (i.e., having a parallelogram-like shape), or other shapes having rotational symmetry of at least second order. In this context, an approximate shape indicates that the basic similarity to the described shape is obvious, but that the sides of the shape in question need not be entirely linear and the vertices need not be entirely sharp. The rounding of both or one of the edges or vertices of a cross-sectional shape is contemplated in the description of any non-circular cross-section referred to herein.

[0055] The cartridge contacts 124a and 124b and the holder contacts 125a and 125b may take various forms. For example, one or both sets of contacts may include conductive pins, printed contacts, contact posts, receiving holes for pins or contact posts, or the like. Some types of contacts may include springs or other features that provide better physical and electrical contact between contacts on the vaporizer cartridge 120 and the vaporizer body 110 . The electrical contacts may not necessarily be gold plated and/or may include other materials.

[0056] FIG. 1B-1D illustrate an embodiment of the vaporizer main body 110 having a cartridge holder 118 into which the vaporizer cartridge 120 can be removably inserted. Fig. 1B and 1C show top views of the vaporizer device 100, illustrating the vaporizer cartridge 120 positioned for insertion and inserted, respectively, into the vaporizer main body 110. Fig. 1D illustrates a reservoir 140 of a vaporizer cartridge 120 formed in whole or in part from a translucent material such that a level of vaporizer 102 is visible from a window 132 (eg, translucent material) on the vaporizer cartridge 120. The evaporator cartridge 120 may be configured such that the window 132 remains visible when inserted by the evaporator cartridge holder 118 of the evaporator main body 110. For example, in one exemplary configuration, window 132 may be located between the lower edge of the mouthpiece 130 and the upper edge of the vaporizer body 110 when the vaporizer cartridge 120 is coupled to the cartridge holder 118.

[0057] FIG. 1E illustrates an exemplary air flow path 134 created during a user's puff on vaporizer device 100. Air flow path 134 may direct air into a vaporization chamber 150 (see FIG. 1F) contained within the wick body, where the air combines with a respirable aerosol for delivery to the user via a mouthpiece 130, which may also be part of a vaporizer cartridge 120. For example, when a user takes a puff on the vaporizer device 100 of the device 100, air may flow between the outer surface of the vaporizer cartridge 120 (e.g., window 132 shown in FIG. 1D) and the inner surface of the cartridge holder 118 on the vaporizer body 110. Air may then be drawn into the insertion end 122 of the vaporizer cartridge 120, through the vapor chamber 150 that includes or contains a heating element and wick, and out through the outlet 136 of the mouthpiece 130 to deliver an inhalable aerosol to the user.

[0058] As shown in FIG. 1E, this configuration causes air to flow around the insertion end 122 of the vaporizer cartridge 120 into the cartridge holder 118 and then flow back in the opposite direction after passing around the insertion end 122 (e.g., the end opposite the end including the mouthpiece 130) of the vaporizer cartridge 120 when it enters the main body of the cartridge toward the vaporization chamber 150. The air flow path 134 then moves through the interior of the vaporizer cartridge 120, for example, through one or more tubes or internal channels (such as cannula 128 shown in FIG. 1F) and through one or more outlet openings (such as outlet 136) formed in the mouthpiece 130. The mouthpiece 130 may be a separable component of the vaporizer cartridge 120 or may be integrally formed with other component(s) of the vaporizer cartridge 120 (e.g., formed as an integral structure with the reservoir 140 and/or etc.).

[0059] FIG. 1F shows additional features that may be included in the vaporizer cartridge 120 consistent with implementations of the current subject matter. For example, vaporizer cartridge 120 may include a plurality of cartridge contacts (such as cartridge contacts 124a, 124b) disposed at the insertion end 122. Each of the cartridge contacts 124a, 124b may optionally be part of a single piece of metal that forms a conductive structure (such as conductive structure 126) connected to one of the two ends of the resistive heating element. The conductive structure may optionally form opposite sides of the heating chamber and may also act as thermal shields and/or heat sinks to reduce heat transfer to the outer walls of the evaporator cartridge 120. Fig. 1F also shows a cannula 128 in the vaporizer cartridge 120 that defines a portion of the air flow path 134 between the heating chamber formed between the conductive structure 126 and the mouthpiece 130.

[0060] As mentioned above, existing cartridges may include a wicking element that is typically configured to draw vaporizable material from the reservoir body such that the volatile substance can subsequently be vaporized (e.g., by subjecting the drawn vaporizable substance to heat provided by heating element). This drawing of vaporized substance from the reservoir body may be due, at least in part, to capillary action provided by the wick, which draws vaporized substance along the wick toward the vaporization chamber. As a result, the evaporated substance is supplied to the absorbent element through capillary action. However, the amount of capillary action may depend at least in part on the absorbent material itself (e.g., type of absorbent material, dimensions of the absorbent material (e.g., length), absorption rate of the absorbent material) and on the amount of vaporizer contained in the reservoir body to replenish the absorbent element. As a result, a consistent rate of vaporization into the flash chamber may be difficult to achieve and/or maintain due to changes in the amount of capillary action present in the wick.

[0061] In such circumstances, the effectiveness of the vaporizer device in vaporizing the desired amount of vaporizable substance, such as when a user takes a puff on the vaporizer device, may be reduced. Various features and devices are described below that improve or overcome these problems. For example, various features are described herein that replace the wicking element with a pumping mechanism that is configured to pump vaporizable material from the reservoir body into the flash chamber at a controlled rate of delivery. Implementing a pumping mechanism, as opposed to using a wicking element, can provide advantages and improvements over existing approaches while also providing additional benefits as described herein.

[0062] The vaporizer cartridges described herein provide the ability to control the delivery of vaporizable material from a reservoir body at a matched delivery rate. Vaporizer cartridges generally include a first storage chamber and a second storage chamber, each having a vaporizable substance disposed therein. The evaporator cartridge further includes an evaporation chamber having an elongated member in fluid communication with the first storage chamber and the second storage chamber. As discussed in more detail below, a magnetic element is located in the elongated element and is configured to selectively oscillate between a first position and a second position so as to substantially control the flow of vaporizable material into the elongated element for vaporization. The magnetic element moves from the first position to the second position in response to the first driving force and from the second position back to the first position in response to the second driving force. These driving forces are generated by a conductive element that is in connection with a magnetic element. The conductive element is also configured to evaporate the evaporable substance in the elongated element. As such, the conductive element may be configured to provide driving forces to oscillate the magnetic element, as well as the heat necessary to vaporize the vaporized substance.

[0063] FIG. 2A-2B illustrate an exemplary vaporizer cartridge 200 that can be selectively attached to and removed from a vaporizer body, such as the vaporizer body 110 shown in FIG. 1A-1D). More specifically, the vaporizer cartridge 200 includes a vaporization chamber 210 having an elongated member 212 that is configured to receive vaporizable material from the first storage chamber 202 and the second storage chamber 204, and a magnetic member 224 that is configured to selectively oscillate between the first position and a second position in the elongated element 212 so as to substantially control the flow of vaporized material into the elongated element 212. For the sake of clarity, certain components of the vaporizer cartridge 200 are not illustrated.

[0064] As shown, the first storage chamber 202 and the second storage chamber 204 are spaced apart from each other such that the first storage chamber 202 and the second storage chamber 204 are each defined by separate walls. That is, the first storage chamber 202 is defined by a first top wall 202a, a first bottom wall 202b that opposes the first top wall 202a, and two opposing first side walls 202c, 202d extending therebetween, and a second storage chamber 204 is defined by a second top wall 204a, a second bottom wall 204b that opposes the second top wall 204a, and two opposing side walls 204c, 204d extending between them. The first storage chamber 202 is configured to hold a first portion of vaporizable substance 206, and the second storage chamber 204 is configured to hold a second portion of vaporizable substance 208. The first portion of vaporizable substance 206 and the second portion of vaporizable substance 208 are collectively referred to herein as “volatiles.”

[0065] While the shape and size of the first and second storage chambers 202, 204 may vary, each chamber, as shown in FIG. 2A-2B is substantially rectangular. The shape and size of the first storage chamber 202 and the second storage chamber 204 may also vary relative to each other. Therefore, the shape and size of the first storage chamber 202 and the second storage chamber 204 are not limited to those illustrated in FIG. 2A-2B. Additionally, the first storage chamber 202 and/or the second storage chamber 204 may include at least one vent hole that is configured to substantially allow air to pass into the respective storage chamber from the environment, thereby essentially maintain an internal pressure (eg, an internal pressure that is substantially equal to the ambient pressure) of the respective storage chamber. As such, the at least one vent hole may reduce or eliminate any negative pressure that is created when vaporized material flows from the first storage chamber 202 or the second storage chamber 204. The at least one vent may be a passive valve or an active valve.

[0066] In general, as discussed above, the vaporization chamber 210 includes an elongated member 212 that is configured to receive vaporizable material from the first storage chamber 202 and the second storage chamber 204. As shown in FIG. 2A-2B, the elongated member 212 extends from the first storage chamber 202 to the second storage chamber 204.

[0067] While elongated member 212 can have a variety of configurations, elongated member 212 is shown to be substantially cylindrical (e.g., tube-shaped) and extends from first end 212a to second end 212b with channel 214 extending between them. The first end 212a is positioned in the first storage chamber 202 and the second end 212b is positioned in the second storage chamber 204 such that the channel 214, and thus the elongated element 212, is in fluid communication with the first and second storage chambers 202, 204 . The elongated member 212 may be formed from any suitable material that is configured to allow vaporized material (aerosol) to pass through it. As discussed in more detail below, the vaporizable substance that flows into the elongated element 212 is vaporized to form the vaporized substance (eg, an aerosol) by the heat generated by the conductive element 228 in response to either the first electrical current or the second electrical current.

[0068] Each end of the elongated member 212 includes an inlet that is configured to allow vaporizable material 206 to flow into the channel 214, and thus into the elongated member 212. As shown in FIG. 2A-2B, the first end 212a includes a first inlet 216, and the second end 212b includes a second inlet 218 that allows vaporized material to flow into the channel 214, and thus into the elongated member 212 from the first chamber 202 storage and a second storage chamber 204, respectively, for evaporation to obtain vaporized substance.

[0069] The first and second inlet ports 216, 218 may have a variety of shapes and/or sizes. For the sake of simplicity, only the first inlet 216 will be discussed herein with respect to size. However, one skilled in the art will appreciate that the following discussion applies equally to the second inlet 218.

[0070] For example, the first inlet 216 may have a diameter that is sized to substantially prevent the first portion of vaporizable material 206 from passing through it when the internal pressure of the first storage chamber 202 is substantially equal to the ambient pressure outside the first chamber 202 storage That is, the first inlet 216 may include a diameter that is sized such that a surface tension of the second lobe of vaporizable substance 206 is created to thereby substantially prevent such vaporizable substance from passing through it, and thus from the first storage chamber 202 when the pressure equalizes at the ends of the first inlet 216.

[0071] Additionally, in some embodiments, one or more inlet valves may be located at the first end 212a and/or the second end 212b of the elongated member 212. The one or more inlet valves may be configured to substantially prevent backflow of vaporized fluid. material in channel 214 of elongated member 212 into one of the storage chambers through one of the inlets of elongated member 212. For example, as shown in FIG. 2A-2B, the first inlet valve 220 is positioned at the first end 212a of the elongated member 212 to substantially prevent a portion of the first portion of vaporizable material 206 in the elongated member 212 from flowing back into the first storage chamber 202. As further shown in FIG. 2A-2B, a second inlet valve 222 is positioned at the second end 212b of the elongated member 212 to substantially prevent the second portion of vaporizable material 208 in the elongated member 212 from flowing back into the second storage chamber 204. As such, the first inlet valve 220 and the second inlet valve 222 may each substantially function as a check valve that is configured to substantially allow the flow of vaporized material into the elongated member 212 while also being configured to essentially prevent the backflow of evaporated material from the elongated element 212.

[0072] As discussed above, a magnetic element 224 is located in a channel 214 of the elongated element 212. The magnetic element 224 is configured to selectively oscillate between a first position (for example, as shown in FIG. 2A) and a second position (for example, as shown in FIG. 2B). This oscillation between the first position and the second position may cause the vaporizable substance 206 to flow alternately from the first storage chamber 202 and from the second storage chamber 204. For example, when in the first position (FIG. 2A), the magnetic element 224 is configured to substantially prevent the first portion of vaporizable material 206 from flowing into the elongated element 212, and when in the second position (FIG. 2B), the magnetic element 224 is configured to the ability to substantially prevent a second portion of the vaporizable material 208 from flowing into the elongated element 212. As such, the oscillation of the magnetic element 224 largely controls the delivery of the volatile material into the elongated element 212. Additionally, the magnetic element 224 in combination with the size of the inlet holes of the elongated element 212 can also regulate the flow of vaporizable substance into the elongated element 212. As a result, a matched delivery rate of vaporizable substance can be delivered to the vaporization chamber 210 for vaporization.

[0073] Magnetic element 224 can have a variety of configurations and sizes. For example, as shown in FIG. 2A-2B, the magnetic element 224 is substantially rectangular. Additionally, magnetic element 224 may be formed from any suitable material that can be magnetized, such as iron, nickel, cobalt, and the like. In one embodiment, the magnetic element 224 is a permanent magnet.

[0074] As discussed above, in use, the magnetic element 224 moves from a first position to a second position in response to a first driving force and from a second position back to a first position in response to a second driving force. The first driving force and the second driving force are generated by the conductive element 228 in response to the conductive element 228 receiving the first electric current and the second electric current, respectively.

[0075] The conductive element 228 may have a variety of configurations, which essentially allow the conductive element 228 to be in selective connection with the magnetic element 224 so as to influence the oscillation of the magnetic element 224 in response to the first and second driving forces. For example, conductive member 228, as shown in FIG. 2A-2B is a conductive coil that is substantially wound around the elongated member 212. The conductive member 228 may be formed from any suitable electrically and thermally conductive material such as iron, carbon steel, stainless steel, aluminum, copper, brass, bronze, electrically conductive ceramic and polymer composites, or other materials suitable for inductive heating.

[0076] The conductive member 228 is connected to a power source, such as the power supply 112 in the evaporator main body 110 shown in FIG. 1A-1D. The power supply, when energized (e.g., when a user takes a puff on a mouthpiece, such as mouthpiece 232 shown in FIGS. 2A-2B), supplies alternating currents (e.g., a first electrical current and a second electrical current having reverse or opposite polarity to the first electrical current) to the conductive member 228. For example, in some embodiments, the vaporizer cartridge 200 includes two or more cartridge contacts, such as, for example, a first cartridge contact 234a and a second cartridge contact 234b. Two or more cartridge contacts may be configured to connect, for example, to holder contacts 125a and 125b to form one or more electrical connections to power supply 112. The circuitry implemented by these electrical connections may enable the delivery of electrical currents to conductive element 228.

[0077] In response to the application of alternating currents, the conductive element 228 generates alternating magnetic fields. Essentially, these alternating magnetic fields act on the magnetic element 224, causing the magnetic element 224 to oscillate from a first position to a second position or vice versa in response to an applied current. That is, in use, when the conductive element 228 receives a first current that has a first polarity, the conductive element 228 generates a first magnetic field that provides a first driving force to drive the magnetic element 224 from the first position to the second position, and when the conductive element element 228 receives a second current that has a second polarity that is opposite to the first polarity, the current-carrying element 228 generates a second magnetic field that provides a second driving force to drive the magnetic element 224 from the second position to the first position. Thus, alternating currents applied to conductive element 228 enable conductive element 228 to generate alternating magnetic fields that drive magnetic element 224.

[0078] Additionally, alternating magnetic fields generated by the current-carrying element 228 pass through the elongated element 212, causing eddy currents. These eddy currents heat the elongated element 212 to a temperature that is at least substantially equal to the vaporization temperature of the substance being vaporized. As a result, a portion of the vaporizer (eg, a portion of the first vaporizer portion 206 or the second vaporizer portion 208) flows into the elongate member 212 and is then vaporized to form a vaporizer (eg, an aerosol). This vaporized material may then combine with, and be carried away from, the vapor chamber 210 by air 230 passing through an air flow passage, such as an air flow passage 229, of the vapor chamber 210. As such, the conductive member 228 may be configured to substantially provide driving forces to drive the magnetic element 224 to allow the vaporizable substance to flow into the elongated element 212 and to substantially vaporize the vaporizable substance in the elongated element 212.

[0079] The first and/or second electrical current applied to and received by conductive member 228 may be adjusted, for example, by providing an adjustment mechanism such as a pulse width modulator, an adjustable resistor, or the like. in the electrical circuit connecting the power source and the current-carrying element 228. Alternatively, or additionally, the adjustment mechanism includes a simple switch in the circuit.

[0080] Additionally, the speed at which the magnetic element 224 oscillates can be adjusted by adjusting the frequency of the alternating currents. In some embodiments, a direct current may be applied to the conductive element 228 to shift the alternating currents so as to separate the heat of the elongated element 212, and thus the evaporation of the evaporated substance within it, from the vibration of the magnetic element 224. That is, application of alternating current may stop the magnetic element 224 from oscillating while heating the elongated element 212.

[0081] While the vapor chamber 210 can have a variety of configurations, the vapor chamber 210 as shown in FIG. 2A-2B is defined by two opposing side walls 210a, 210b and a bottom wall 210c extending between them. The first side wall 210a of the vapor chamber 210 is also one of the side walls 202c of the first storage chamber 202, and the second side wall 210b of the vapor chamber 210 is also one of the side walls 202c of the second storage chamber 204. As such, in this illustrated embodiment, the vapor chamber 210 is at least partially defined by the first and second storage chambers 202, 204. As shown, the vapor chamber 210 defines a passageway 229 for air flow that passes through it.

[0082] The air flow passage 220 is configured to direct air, illustrated by the broken line arrow 230, through the vaporization chamber 210, so that the air 230 will be mixed with the vaporized substance to form an aerosol, illustrated by the broken line arrow 231. The air flow passage 229 further directs the aerosol 231 through the outlet 211 of the vaporization chamber 210, and thus the mouthpiece 232 connected to the vaporizer cartridge 200, for inhalation by the user. While mouthpiece 232 is shown in FIG. 2A-2B, one skilled in the art will appreciate that in other embodiments, the mouthpiece 232 may be omitted and the user may directly draw on the cartridge 200 at the outlet (such as the outlet 211 of the vapor chamber 210).

[0083] In some embodiments, at least one wall of the vapor chamber 210, such as side wall 210a and/or side wall 210b, may be formed of, or coated with, a water-repellent material to prevent the accumulation of any condensation in the flash chamber 210. Essentially, any water that may be present in the aerosol 231 and air 230 may be transferred through and out of the flash chamber 210 when the user takes a puff on the mouthpiece 232.

[0084] Air 230 enters the vapor chamber 210 through the bottom wall 210c when the user takes a puff on the mouthpiece 232. As such, the bottom wall 210c is configured to allow air 230 to easily pass through it and into the vapor chamber 210. While The bottom wall 210c can have a variety of configurations, the bottom wall 210c is perforated, as shown in FIG. 2A-2B. The perforated holes can be of any suitable size that allows air to pass through the bottom wall 210c. In some embodiments, the size of the perforated openings may substantially prevent any spillage of vaporizable material from the first or second storage chambers 202, 204 or passage of aerosol 231 through the bottom wall 210c and therefore prevent unwanted leakage into other areas of the vaporizer body, such as the evaporator main body 110 shown in FIG. 1A-1D connected to the vaporizer cartridge 200. The bottom wall 210c may include any suitable number of perforations, and therefore the number of perforations is not limited to the number that is illustrated in FIG. 2A-2B. Alternatively or in addition, the bottom wall 210c may be formed from a breathable material. Thus, the bottom wall 210c functions as an air inlet for the evaporation chamber 210.

[0085] The bottom wall 210c may also be configured to prevent air 230 and/or aerosol 231 from passing through it in the flash chamber 210. That is, the bottom wall 210c may be configured as a one-way valve and therefore allow air 230 pass only through and into the vapor chamber 210. In some embodiments, any of the remaining walls of the vapor chamber 210 may be perforated and/or formed from a breathable material to allow air to pass into (or out of) the vapor chamber 210 as desired.

Terminology

[0086] For purposes of describing and defining these teachings, it is noted that, unless otherwise noted, the term “substantially” is used herein to represent the inherent degree of uncertainty that may be inherent in any quantitative comparison, value, measurement or other representation. The terms “substantially” are also used herein to represent the extent to which a quantitative presentation may vary from an established standard without resulting in a change in the essential function of the subject matter.

[0087] When a feature or element is referred to herein as being "in" another feature or element, it may be directly contained in the other feature or element, or intermediate features and/or elements may also be present. In contrast, when a feature or element is referred to as being "directly contained" in another feature or element, no intermediate features or elements are present. It should also be understood that when a feature or element is referred to as being "connected or "attached" to another feature or element, it may be directly connected or attached to the other feature or element, or intermediate features or elements may be present. In contrast, when the feature or element is referred to as "directly connected" or "directly attached" to another feature or element, no intermediate features or elements are present.

[0088] Although described or shown in relation to one embodiment, the features and elements described or shown in this manner may apply to other embodiments. Those skilled in the art will also appreciate that references to a structure or feature that is located “next to” another feature may have portions that overlap or underlie the adjacent feature.

[0089] The terminology used herein is for the purpose of describing specific embodiments and implementations only and is not intended to be limiting. For example, as used herein, singular forms are intended to include plural forms unless the context clearly indicates otherwise.

[0090] In the above descriptions and in the claims, phrases such as “at least one of” or “one or more of” may appear followed by a conjunctive list of elements or features. The term "and/or" may also appear in a list of two or more elements or features. Unless otherwise implicitly or explicitly inconsistent with the context in which it is used, such phrase is not intended to mean any of the enumerated elements or features alone or any of the enumerated elements or features in combination with any of the other enumerated elements or features. For example, the phrases "at least one of A and B"; "one or more of A and B"; and "A and/or B" are intended to mean "A only, B only, or A and B together." A similar interpretation also applies to lists containing three or more elements. For example, the phrases "at least one of A, B and C"; "one or more of A, B and C"; and "A, B and/or C" are intended to mean "A only, B only, C only, A and B together, A and C together, B and C together, or A and B and C together." The use of the term "based on" above and in the claims is intended to mean "at least in part based on" so that an unstated feature or element is also acceptable.

[0091] Spatially relative terms such as “front”, “back”, “under”, “below”, “lower”, “above”, “top”, etc. may be used herein for ease of description to describe one element or relationship of a feature in relation to another element(s) or feature(s), as illustrated in the drawings. It should be understood that spatially relative terms are intended to cover various orientations of the device being used or operated, in addition to the orientation illustrated in the drawings. For example, if the device in the drawings is inverted, elements described as "under" or "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "under" can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly. Likewise, the terms “up”, “down”, “vertical”, “horizontal”, etc. are used herein for explanatory purposes only unless expressly stated otherwise.

[0092] Although the terms “first” and “second” may be used herein to describe various features/elements (including steps), these features/elements should not be limited by these terms unless the context indicates otherwise. These terms can be used to distinguish one characteristic/element from another characteristic/element. Thus, the first feature/element explained below may be referred to as the second feature/element, and likewise, the second feature/element explained below may be referred to as the first feature/element, without departing from the ideas provided herein.

[0093] When used herein in the detailed description and claims, including when used in examples, and unless otherwise expressly indicated, all numbers may be read as if preceded by the word "about" or "approximately" even if the term is not shown explicitly. The phrase "about" or "approximately" may be used when describing an absolute value and/or position to indicate that the value and/or position described is within a reasonable expected range of values and/or positions. For example, a numeric value may have a value that is +/-0.1% of a set value (or range of values), +/-1% of a set value (or range of values), +/-2% of a set value (or value range), +/-5% of the set value (or range of values), +/-10% of the set value (or range of values), etc. Any numerical values given herein should also be understood to include about or approximately that value unless the context otherwise indicates. For example, if the value "10" is disclosed, then "about 10" is also disclosed. Any range of numerical values set forth herein is intended to be inclusive of all subranges included therein. It should also be understood that when a value that is “less than or equal to” a value is disclosed, a “greater than or equal to a value” and possible ranges between the values are also disclosed, as those skilled in the art would appreciate. For example, if the value "X" is disclosed, "less than or equal to X" is also disclosed, as is "greater than or equal to X" (eg, where X is a numeric value). It should also be understood that in this application, data is provided in a number of different formats, and that this data represents end points and starting points and ranges for any combination of data points. For example, if a particular data point "10" and a particular data point "15" are disclosed, it should be understood that greater than, greater than or equal to, less than, less than or equal to, and equal to 10 and 15 are considered disclosed, as are between 10 and 15. It should also be understand that each unit between two specific units is also disclosed. For example, if 10 and 15 are revealed, then 11, 12, 13 and 14 are also revealed.
