DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
According to the prior art as shown in FIG. 1-3, an outside of a connection base 900 needs to be sleeved with a flexible glue seal ring 800 to achieve a good sealing effect. However, it is prone to appear a problem that a sealing effect is bad and an assembly is difficult in the aforementioned method during the assembly process. Therefore, the present invention aims at the connection base 900 of an electronic cigarette to improve the connection base 900.
FIGS. 4-6 illustrate a first embodiment of the present invention. Wherein, a connection base 900 comprises a top cover 903, a side wall 902 is formed around an edge of the top cover 903; the side wall 902 defines a filling groove around an outer surface of the side wall 902; and the filling groove 901 is filled with seal filler, for example, adhesive, such as different kinds of suitable glue. After filled with glue, the connection base 900 is embedded from the bottom of an atomization outer sleeve 200, and the outside of the side wall 902 of the connection base 900 is in tight contact with the atomization outer sleeve 200. In order to make the connection base 900 be in tight contact with the atomization outer sleeve 200, diameters of the connection base 900 and the atomization outer sleeve 200 should match with each other, and a complete electronic cigarette atomization device is formed in the way of interference fit or engagement. Additionally, the connection base 900 is chamfered, so that the connection base 900 is more easily embedded into the atomization outer sleeve 200. A through-hole 904 is defined in the top cover 903. An electrode of the atomization device extends through the through-hole 904, and connects with a corresponding electrode of the battery rod device. An inside of the side wall 902 of the connection base 900 forms a thread, so that the atomization device 1 is connected with the battery rod device 2 in the way of screwed connection.
In the first embodiment of the present invention, the filling groove 901 is formed to be an annular groove around the outside of the side wall of the connection base 900. There may be one annular groove or a plurality of annular grooves; and the annular grooves are all parallel to each other. When the glue filled in the annular grooves is dried, the gap formed between the connection base 900 and the atomization outer sleeve 200 is completely stuffed and achieves the sealing for the smoke oil.
The atomization device, with the connection base 900 of the present invention mounted thereon, further includes a nozzle 100, an oil storage cotton 300, a fiberglass tube 400, a heating wire element 500, an upper electrode 600, and an insulating ring 700, which are disposed in the atomization outer sleeve 200, and are successively arranged from the top to the bottom of the atomization outer sleeve 200. The upper electrode 600 runs through the insulating ring 700, and the insulating ring 700 is secured in the through-hole 904 defined in the top cover of the connection base 900, so that the connection base 900 is electrically isolated with the upper electrode 600. The fiberglass tube 400 is hollow, and is positioned inside of the atomization outer sleeve 200 and separated from the inner wall of the atomization outer sleeve 200 with a gap. The oil storage cotton 300 is positioned in the gap. The heating wire element 500 heats and atomizes the tobacco juice stored in the oil storage cotton 300. The atomized smoke oil flows along the hollow fiberglass tube 400, and flows out via the nozzle 100.
In the present invention, the filling groove 901 of the connection base 900 may be in other shapes. For example, in a second embodiment of the present invention as shown in FIG. 7, the filling groove 901 includes straight line grooves which are perpendicular to the top cover (i.e., positioned along an axial direction of the periphery surface of the side wall of the connection base). Every two adjacent ones of these straight line grooves are parallel to each other and are separated with a certain distance. When the filling groove 901 is filled with glue and replaces the connection base 900 shown in FIG. 4 and FIG. 6, the sealing for the oil storage cotton 300 can also be achieve.
Two kinds of the filling grooves mentioned above have different advantages: in the first embodiment, the annular filling groove is corresponding to the inner wall of the whole atomization outer sleeve 200, therefore, the sealing effect is better; in the second embodiment, the longitudinal straight line filling groove can enhance the pivoting friction generated when the connection base 900 is rotating with respect to the atomization outer sleeve 200, therefore, the battery rod device 2 can be more firmly screwed connected with the atomization device 1.
Based on the two kinds of the filling grooves above, there can be more changes. For example, the longitudinal straight line grooves may be formed into oblique straight line grooves, that is, there may be a certain angle between the straight line grooves and the plane of the top cover of the connection base, wave-shaped grooves or arc-shaped grooves. Another example is that both the annular grooves of the first embodiment and the longitudinal straight line grooves of the second embodiment are formed in the connection base 900, so that the connection base 900 can combine the advantages of both two kinds of the filling grooves.
In order to prevent the connection base 900 from loosening when the connection base 900 is embedded into the atomization outer sleeve 200, usually the outer diameter of the connection base 900 is configured to be equal to the inner diameter of the atomization outer sleeve 200, so that the connection base 900 can engage with the atomization outer sleeve 200. The inner diameter of the atomization outer sleeve can also be slightly smaller than the outer diameter of the connection base 900, so that the connection base 900 can be interference fitted with the atomization outer sleeve 200. Since the outside of the side wall of the connection base 900 is not sleeved with the seal ring 800, the connection base 900 will not be resisted by the friction of seal ring 800 when the connection base 900 is sleeved into the atomization outer sleeve 20, which makes the assembly process easier.
A third embodiment of the present invention is shown as FIGS. 8-10. In the third embodiment, the filling groove is defined to mesh grooves, and includes two groups of the angularity twill grooves crossing each other and forming the latticed grooves as shown in FIG. 8 and FIG. 9. The advantage for using this kind of filling groove is that, the crossing grooves communicate with each other, and when the filling groove is filled with glue or adhesive in one place, the glue or adhesive can flow along the communicating grooves to the whole filling groove 901. Therefore, the method to fill the glue is simpler, and the glue is more distributed. Additionally, the filling groove is distributed on the whole outer wall of the electronic cigarette connection base 900, the connection base 900 is better fitted with the atomization outer sleeve 200, and the electronic cigarette connection base 900 is more secured.
Those mentioned above are the detailed descriptions of the embodiments, and do not imply a limitation to the protection scope of the present invention. In the inspiration of the present invention, those ordinary skills in the art can also make many modifications without breaking away from the subject of the present invention and the protection scope of the claims. All these modifications belong to the protection of the present invention.
