The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, fig. 2 and fig. 3, an electronic cigarette according to an embodiment of the present invention includes a power supply device (not shown) and an atomizing device 100 coupled to an end of the power supply device. The power supply device is used for supplying power to the atomization device 100. The atomization device 100 is used for storing atomized liquid and heating the atomized liquid under the electric drive of the power supply device, so that the atomized liquid is atomized to form smoke for a user to suck. It should be noted that the specific structure of the power supply device is substantially the same as that of the power supply device in the prior art, and therefore, the detailed description thereof is omitted here.

The atomization device 100 includes a liquid storage case 10, an atomization core 30 accommodated in the liquid storage case 10, and a vent pipe 40 accommodated in the liquid storage case 10. The liquid storage shell 10 is provided with a liquid storage cavity 16 for storing atomized liquid, the atomizing core 30 is electrically connected with a power supply device, the atomizing core 30 is used for sucking the atomized liquid in the liquid storage cavity 16 and atomizing the atomized liquid, and the generated smoke flows into the ventilation pipe 40 and is finally inhaled by a user.

Specifically, reservoir housing 10 further includes a fluid injection passage 1222 (see fig. 3) that communicates reservoir chamber 16 with the external environment. The atomising device 100 also comprises a sealing plug 20. A sealing plug 20 is inserted into the filling channel 1222 to open or close the reservoir 16. In this manner, when the liquid filling passage 1222 is not installed with the sealing plug 20, the atomized liquid can be filled into the liquid storage chamber 16 through the liquid filling passage 1222. After the sealing plug 20 is inserted into the liquid filling channel 1222 to close the liquid storage cavity 16, the atomized liquid cannot flow out of the liquid storage cavity 16 through the liquid filling channel 1222.

In some embodiments, the sealing plug 20 includes a sealing plug body 22 and an elastomeric sealing sleeve 24 that fits over the sealing plug body 22. The elastic sealing sleeve 24 seals the liquid storage cavity 16, and the sealing plug body 22 is exposed outside the liquid storage shell 10 and can generate magnetic attraction reaction with the magnetic element to attract each other. Specifically, in the embodiment, a magnetic element is disposed at one end of the power supply device, which is connected to the atomizing device 100, and the magnetic element can be connected to the sealing plug body 22 of the atomizing device 100 under the magnetic attraction effect, so that the atomizing device 100 is connected to the power supply device.

The plug body 22 is made of a magnetic material that magnetically reacts with the magnet, for example, a magnet, iron, steel, or the like. The magnetic element may be a magnet or an electromagnet. In other embodiments, plug body 22 and the magnetic element may be made of other materials and magnets, as long as plug body 22 and the magnetic element can be attracted to each other, and the embodiments are not limited herein.

Thus, the atomizing device 100 is connected with the power supply device through the magnetic attraction effect through the sealing plug body 22, so as to replace a buckle structure which is easy to wear and lose efficacy in the prior art, and the atomizing device 100 and the power supply device can be conveniently, quickly and stably connected for a long time. Moreover, since the sealing plug body 22 is used for sealing the liquid injection channel 1222 and is also used for connecting a power supply device, a structure for connecting the power supply device is not required to be separately arranged in the atomization device 100, so that the structure of the atomization device 100 is simplified, and the size miniaturization of the atomization device 100 and the electronic cigarette is facilitated.

It should be noted that there is a risk of the plug body 22 loosening due to the mutual attraction of the plug body 22 and the magnetic element of the power supply device. In the specific embodiment, the sealing plug body 22 is riveted in the liquid injection channel 1222, and the elastic sealing sleeve 24 is in interference fit with the inner wall of the liquid injection channel 1222, so that the sealing plug body 22 and the elastic sealing sleeve 24 both play a role in sealing the liquid injection channel 1222, a double sealing effect is achieved, even if the sealing plug body 22 is loosened, the sealing effect of the elastic sealing sleeve 24 cannot be affected, and the risk of oil leakage is effectively reduced.

Further, the circumferential surface of the elastic sealing sleeve 24 is convexly provided with at least one annular rib 240. That is, each annular bead 240 is disposed about the central axis of the elastomeric sealing boot 24. In this way, the provision of the annular rib 240 further improves the sealing effect of the elastic sealing sleeve 24. It will be appreciated that when two or more annular ribs 240 are provided, the ribs 240 are spaced apart along the central axis of the elastomeric sealing boot 24.

Alternatively, the elastomeric sealing boot 24 may be a silicone sealing boot. Silica gel is good in chemical stability, non-toxic, odorless and not easy to burn, so that the silica gel sealing sleeve cannot react with the atomized liquid to pollute the atomized liquid or generate substances harmful to the body of a user.

In one embodiment, elastomeric sealing boot 24 includes a boot bottom wall 242 and a boot sidewall 244 extending from an edge of boot bottom wall 242 in the same direction. A sealing boot sidewall 244 surrounds the sealing boot bottom wall 242 and together with the sealing boot bottom wall 242 forms an open-ended receiving cavity. The end of the sealing plug body 22 adjacent to the reservoir 16 is sleeved in the accommodating cavity by the open end of the elastic sealing sleeve 24. In this manner, seal cartridge bottom wall 242 and seal cartridge side wall 244 of elastomeric seal cartridge 24 completely encapsulate the end of sealing plug body 22 adjacent to reservoir 16, preventing sealing plug body 22 from contacting the atomized liquid and causing chemical reaction.

Note that the gland sidewall 244 has an interference fit with the plug body 22. The seal cartridge sidewall 244 is an interference fit with the inner wall of the injection passage 1222. Further, the plug body 22 is provided with an annular groove. The inside of the sealing sleeve side wall 244 is provided with an annular projection which mates with the annular recess to prevent separation of the resilient sealing sleeve 24 from the plug body 22.

The embodiment of the utility model provides an in, stock solution casing 10 includes liquid storage cylinder 12 and

suction nozzle lid

14, and 12 one end of liquid storage cylinder are located to the 14 detachably cover of suction nozzle lid, and the one end that the suction nozzle lid 14 was kept away from to liquid storage cylinder 12 is inserted and is located in power supply unit.

In some embodiments, the cartridge 12 includes a reservoir bottom wall 122 and a reservoir side wall 124. The liquid storage side wall 124 is formed to extend from the edge of the liquid storage bottom wall 122 toward the same direction. The liquid storage side wall 124 surrounds the liquid storage bottom wall 122 and forms a liquid storage cavity 16 with one end open together with the liquid storage bottom wall 122. Liquid injection channel 1222 communicating liquid storage cavity 16 with the external environment is opened through liquid storage bottom wall 122.

In the embodiment, two filling channels 1222 are spaced apart from the bottom wall 122, and each filling channel 1222 is inserted with a sealing plug 20. In this way, the atomization device 100 injects the atomized liquid in a bottom injection manner. When the atomized liquid is injected into the liquid storage cavity 16, the atomizing device 100 is in an inverted state, the two liquid injection channels 1222 can be opened simultaneously, and the user injects the atomized liquid into the liquid storage cavity 16 through any one of the liquid injection channels 1222. During filling, gas in reservoir chamber 16 is vented through another fill channel 1222. Therefore, the injected atomized liquid can fill the entire liquid storage chamber 16, thereby preventing the gas in the liquid storage chamber 16 from being discharged and generating negative pressure with the external gas, and finally preventing the atomized liquid from flowing out of the liquid storage chamber 16 under the action of the negative pressure. It is understood that the number of the liquid filling channels 1222 is not limited thereto, and in other embodiments, the liquid storage bottom wall 122 may be spaced apart by a plurality of liquid filling channels 1222 to improve the liquid filling and gas discharging effects.

In one embodiment, the end of the plug body 22 facing away from the reservoir 16 has a magnetic attraction surface 222. The suction surface 222 is substantially flush with a surface of the bottom wall 122 remote from the storage chamber 16 to facilitate the sealing plug body 22 to be more tightly engaged with the magnetic element of the power supply device. Alternatively, the magnetically attractive surface 222 may be a flat surface.

In the embodiment, an atomizing core mounting groove communicated with the liquid storage cavity 16 is formed on one side of the liquid storage bottom wall 122 close to the liquid storage cavity 16. One end of the atomizing core 30 is inserted into the atomizing core mounting groove, and the other end of the atomizing core 30 is located in the liquid storage cavity 16.

Further, atomizing core 30 includes atomizing core casing 32 and atomizing core main part 34, is formed with the atomizing chamber in the atomizing core casing 32, and the lateral wall of atomizing core casing 32 runs through the atomizing hole of seting up intercommunication atomizing chamber and stock solution chamber 16. The atomizing core main body 34 is accommodated in the atomizing cavity of the atomizing core housing 32 and contacts the atomized liquid in the liquid storage cavity 16 through the atomizing hole. Thus, the atomizing core main body 34 accommodated in the atomizing cavity absorbs the atomized liquid in the liquid storage cavity 16 through the atomizing holes, and the atomized liquid is atomized to form smoke.

In the embodiment, two electrode mounting holes 1224 (see fig. 3) are formed through the liquid storage bottom wall 122, and both the electrode mounting holes 1224 are communicated with the mounting grooves of the atomizing core 30. As such, the electrode 60 may be received in the electrode mounting hole 1224 and thereby electrically connected to the atomizing core 30. When the power supply device is mated with the atomizing device 100, the output electrode of the power supply device is in electrical contact with the electrode 60 in the electrode mounting hole 1224, thereby enabling the power supply device to supply power to the atomizing cartridge 30.

In some embodiments, the mouthpiece cover 14 is removably mounted over the open end of the reservoir 12. The nozzle cover 14 includes a nozzle cover top wall 142 and nozzle cover side walls 144. The nozzle cover side wall 144 is formed extending from the edge of the nozzle cover top wall 142 toward the same direction. The nozzle cap side wall 144 surrounds the nozzle cap top wall 142 and forms a nozzle cavity with one end open with the nozzle cap top wall 142. The open end of the reservoir 12 is inserted into the suction nozzle cavity to close the reservoir cavity 16 with the nozzle cap 14.

The top wall 142 of the mouthpiece cover is provided with two air outlets 1422 disposed at intervals, the air outlets 1422 are communicated with the vent pipe 40, and the smoke in the vent pipe 40 is discharged through the air outlets 1422 for the user to suck. It is understood that in other embodiments, the number and size of the air outlets 1422 are not limited, and may be set as desired.

In an embodiment, the outer surface of the liquid storage sidewall 124 is provided with a snap. The side wall of the nozzle cover 14 is provided with a clamping groove. When the nozzle cover 14 covers the liquid storage cylinder 12, the fastener is clamped in the clamping groove on the side wall of the nozzle cover 14, so that the nozzle cover 14 and the liquid storage cylinder 12 are fixedly mounted.

In the embodiment, the vent tube 40 and the atomizing core housing 32 are integrally formed, so that a separate component for fixing the atomizing core 30 and the vent tube 40 is not required, the structure of the atomizing device 100 is further simplified, and the sealing performance is improved.

In particular embodiments, the atomization device 100 further includes a gasket 50. The sealing gasket 50 is mounted at the open end of the liquid storage cylinder 12 and is in interference fit with the liquid storage cylinder 12, the nozzle cover 14 applies pressure to the sealing gasket 50 towards the bottom wall 122 of the liquid storage cylinder, and one end of the vent pipe 40, which is far away from the atomizing core 30, is inserted into the sealing gasket 50. In this manner, the sealing gasket 50 and the nozzle cover 14 together close the open end of the reservoir chamber 16, thereby preventing the atomized liquid in the reservoir chamber 16 from leaking.
