The suction-type atomizer for electric generally is used for the smoking-simulating article or is used for the treatment of the inhalator of the suction medicament of breathing problem.It generally has the rod body part that accommodates power supply and control system, the atomization of liquid portion and the nozzle section that are connected with rod body part.
Compare the typical prior art structure, as Chinese patent ZL200420031182.0, name is called " Atmized electronic cigarrette " disclosed structure, comprise housing and suction nozzle, have air admission hole on the outer wall of housing, be provided with electronic circuit board, common pressure chamber, sensor, gas-liquid separator, atomizer, supplying bottle in the housing successively; Wherein electronic circuit board is made up of electronic switching circuit and radio-frequency generator; Side at sensor has the sensor gas channel, is provided with negative pressure cavity in the sensor; Atomizer contacts with supplying bottle, is provided with atomization chamber in the inside of atomizer; Be provided with the back-up ring of locking supplying bottle between one side of supplying bottle and the housing, the opposite side of supplying bottle has mist vapour passage; Air admission hole, common pressure chamber, gas-liquid separator, atomizer, mist vapour passage, gas port, suction nozzle are connected successively.Though the electronics smoke product of this structure has been made big improvement on bases such as ultrasonic atomizatio that its prior art adopted, mechanical type atomizing, its atomizer utilizes the capillarity of liquid, employing pottery etc. receives the liquid in the supplying bottle to make its high temperature atomizing in ceramic atomization chamber as atomization chamber and by foam metal, on the atomization gas passage gas-liquid separator is set.This kind constructed products, the not only complex structure of its atomizer but also manufacturing cost height, the assembling process of each major function member is difficulty relatively also.
Another money is typical prior art structures relatively, as Chinese patent ZL200710054948.5, name is called " a kind of electronic clean cigarette " disclosed structure, include cigarette holder part and tobacco rod part, described tobacco rod part is made up of tobacco rod housing, battery, sensor, indicator lamp, circuit control panel, indicator-lamp cover, air admission hole, venthole, output etc., and described cigarette holder part is made up of cigarette holder housing, electric heater, tobacco extract, organic fiber, air admission hole, venthole, input etc.This patent is on the prior art basis, a kind of atomizer structure relatively simple for structure has been proposed, being about to suction nozzle and atomizer merges, and its atomizer is to utilize organic fiber to be wrapped in the outside of heater and be filled in the inner chamber of suction nozzle housing, makes the directly liquid that oozes out from organic fiber of heating of heater.But this kind constructed products, because the gap that its gas circuit in suction nozzle is suction nozzle inside, that is to say the gap between the organic fiber, not only the resistance of atomization gas in the way of advancing is very big, the suction that the smoker need be costed a lot of money, and its atomization gas has very major part be adsorbed by organic fiber once more again in the way of advancing, and making to suck has the flavor material less in the gas; Negative pressure when causing sucking greatly owing to gas-flow resistance is big, is very easy to the direct sucking-off of not atomizing bulky grain liquid in the organic fiber.Secondly, the suction nozzle of this structure since its liquid storage in organic fiber and organic fiber fill up whole suction nozzle housing, the liquid in the fiber oozes out along the suction nozzle inner walls from nozzle up and down under the capillarity effect easily.
Secondly, the applicant has also proposed a kind of name on May 14th, 2008, and to be called " electronic cigarette " China Patent No. be the utility model application of ZL20082009977, a kind of electronic cigarette of this Patent publish, comprise tobacco rod assembly, the atomizer assembly by being threaded in tobacco rod assembly one end and be set in cigarette holder on the atomizer assembly, be provided with the cigarette bullet in this cigarette holder.Described tobacco rod assembly comprises housing, be located at the light-emitting device of housing front end, be located at that electric core, an end in the housing is plugged on this housing rear end in and the other end stretch out housing cored screw, be located at the interior jettron that is used to open described atomizer assembly power supply of this cored screw.The utility model has compared with prior art dwindled the outward appearance volume of product greatly, and battery and tobacco rod integrated design, charging, easy to carry.Adopt jettron, action accurately.The anti-leakage design of distinctive cigarette bullet structure and atomizer, the leakage when having solved smoking and placement well is puzzled.According to this design, this kind design has been made bigger improvement aspect control technology, and the control accuracy of sucking process is improved greatly; Secondly aspect package assembly, the electronics cigarette is divided into cigarette bullet assembly (containing suction nozzle), atomizer assembly and the power-supply control unit of independent assembling separately, makes links such as manufacturing, assembling, use very convenient.But, described atomizer still adopts traditional metal foam as the liquid adsorption annex, and atomization gas curved way, the smoker still needs bigger suction suction, require great effort very much when promptly sucking, and because atomizer adopts foam metal and corresponding pottery atomizing skeleton, manufacturing cost inevitably can be than higher.
Summary of the invention
At electronic atomized series products, at present under the relatively mature and stable situation of electron controls technology, invent simple in structure, assembling easily, easy to use and safe atomizer for electric product, the structure of further improving atomizer is an important link.The smoker is easily sucked, thereby can make atomizer structure more simply make assembling, storage and safety easy to use again, be that the design seeks for one of subject matter of solution.For this reason, on the prior art basis, following design is proposed:
A kind of suction nozzle of electronic atomizer, described suction nozzle comprises tubular shell body, the front end nozzle portion of described shell body is provided with suction nozzle screw thread electrode, rear end nozzle portion is provided with the shutoff wall, holds having heaters and can store the reservoir that is atomized liquid in described shell body, suction nozzle screw thread electrode and the formed container cavity of shutoff wall; Described heater is electrically connected with described suction nozzle screw thread electrode, and described suction nozzle screw thread electrode has inside and outside electrode and described suction nozzle screw thread electrode is provided with air admission hole, and described shutoff wall is provided with venthole; It is characterized in that the central part of described reservoir has axial central passage, described central passage is communicated with described air admission hole and described venthole, and described heater is arranged in the described central passage.
Described atomizer for electric, thus the liquid in it can be atomized to suck the utensil of atomization gas for the consumer, including suction nozzle parts and control power supply unit at least, wherein said control power supply unit provides electric energy for described suction nozzle parts.Described suction nozzle is the parts that include reservoir and heater, because described shell body, suction nozzle screw thread electrode and shutoff wall are combined to form container cavity, and described reservoir and heater be contained in the described container cavity, and described for this reason suction nozzle can be used as independently a parts manufacturing and an assembling.In use, can also be with described suction nozzle as disposable accessory, after promptly the liquid in described suction nozzle is finished using,, thereby make described suction nozzle replacing convenient, safe in utilization with regard to the described suction nozzle of whole replacing.
Described reservoir be can storage of liquids parts, can be material manufacturings such as filament, felt or the nontoxic sponge of heatproof, the liquid that is atomized can be stored in the described reservoir in can.Secondly, described reservoir is distributed in the described container cavity, its central part forms axial central passage, this axial direction also is the axial direction of described shell body, this central passage is communicated with described air admission hole and described venthole, and then is convenient to pass apace and discharge from described venthole from the air that described air admission hole enters.This central passage can be positioned at the center of described reservoir, also can be the cross section from described suction nozzle, and described reservoir splits on the both sides of the inner chamber of described shell body, and described central passage is two clearance channel between the described reservoir.
Described suction nozzle screw thread electrode is the conductive electrode that includes internal and external electrode, is separated by insulating materials such as insulation silica gel between the internal and external electrode.Secondly thereby described suction nozzle screw thread electrode is provided with connecting thread and is convenient to and controls the power unit mechanical connection and be electrically connected.The air guiding that described suction nozzle is outer of air admission hole on the described in addition suction nozzle screw thread electrode enters in the central passage of described suction nozzle.
According to technique scheme, choose similar mediums materials such as the reasonable nontoxic sponge of storaging liquid performance, fiber felt silk, and make described reservoir in be formed centrally described central passage, described heater is arranged in the described central passage, notes not allowing described heater stop up the described central passage of described reservoir; Two ends with described heater again are electrically connected by electric wire with the internal and external electrode of described suction nozzle screw thread electrode, more described reservoir is filled in the described shell body, and described suction nozzle screw thread electrode is connected in described shell body front end nozzle portion, in the process of assembling, note allowing described central passage keep unimpeded.Then by special equipment from the nozzle position, rear end of described shell body an amount of atomized liquid of filling to described reservoir quantitatively, at last by special equipment as ultrasonic welding machine or adopt cohere method etc. with as described in the shutoff wall be fixed on as described in the nozzle position, rear end of shell body; So independently described suction nozzle assembling is finished.Wherein said reservoir elastic top is reliably pressed on the madial wall be positioned at described shell body and can not be slided, and described central passage also can be kept unimpeded naturally.
When aspirating the back nozzle position of described suction nozzle with mouth, air enters described central passage from described air admission hole also to be passed through fast.Because air velocity height in the described central passage, its air pressure must be lower than the air pressure in the filament on every side, and the liquid in the described for this reason reservoir can be penetrated on the fiber hair of madial wall of described central passage or in the mesopore and then be diffused in the air-flow and with the air current flow in the described central passage naturally.When these air communication that include liquid were crossed heater, described heater can be heated up them again and further atomizing.The gas liquid mixture that is atomized flows out from described venthole after described central passage flows out again.
According to the said structure and the course of work, contrast with prior art Chinese patent ZL200710054948.5, because the setting of central passage, make described central passage have quick diversion function, not only the suction of user's needs is little, and during air current flow, to infiltration or also further refinement and the atomizing of liquid itself that diffuse out.Secondly when similar materials such as described reservoir use filament, the adsorption capacity of such material itself is far longer than the atomization chamber such as pottery used in the conventional art adsorption capacity to liquid, the area of gas-liquid contact increases, thereby can avoid oarse-grained liquid to be carried out though the direct stream of air-flow carries with adsorptive liquid by described central passage.Further after these mists are heated, again further by refinement or atomizing.In addition, because the setting of central passage, avoided the no Zhang Liudong and cause the big defective of flow resistance of atomization gas in the fibre gap in suction nozzle of air-flow in the prior art, and the defective of having avoided atomization gas not only may be absorbed once more fast by fiber, the fiber temperature height of also having avoided high-temperature gas of the prior art between filament, to flow and having caused, thereby need the power ratio of heater bigger, filametntary heat resistance must very high defective.
Further technical scheme can also be, is being positioned at the stay pipe that is fixed with hollow on the described central passage of at least a portion on described heater top, and the cavity of described stay pipe forms the part of described central passage.Wherein said heater top is meant one section described central passage of the process that also needs after air flow stream is by described heater to continue to circulate; Described stay pipe is a kind of and the adaptive tubular body of the inner chamber of described central passage, preferably similar materials such as the temperature resistant fiber pipe of thin-walled or heatproof plastic tube relatively.According to technique scheme, because the supporting role of described stay pipe, the hollow channel of described stay pipe can allow atomization gas pass through, described stay pipe can prevent that again described reservoir from subsiding in described central passage in assembling or in using and block the outlet passageway of described central passage, can also stop not flowed out with atomization gas of described stay pipe side, force the liquid of described stay pipe side near heater, permeate by the liquid of heater heating atomization.Secondly can also regulate atomized liquid to described central passage infiltration quantity by the described stay pipe design that different length is set.
Can be when reel making described reservoir reel simultaneously and fix described stay pipe, also can after described reservoir completes, assemble described stay pipe again with described heater.Because described stay pipe or described reservoir itself have certain elasticity and can naturally described stay pipe be held tightly in described central passage.Only need described stay pipe is placed in the upper channel of described heater for this reason and get final product, need not adhoc approach and fix.
