BACKGROUND

The disclosure relates to an electronic cigarette.

A conventional electronic cigarette includes an atomization assembly and a battery assembly. The atomization assembly comprises an air inlet and an air passage, and has no double leak-proof functions.

SUMMARY

The disclosure provides a leak-proof device, comprising a first seal ring, an upper cover, a base, a second seal ring, and an insulation ring; the first seal ring is disposed on the top end of the upper cover to seal an e-liquid tank thereby isolating the e-liquid in the e-liquid tank; the base comprises a first recess; the second seal ring is disposed on the base; the base is disposed on the bottom end of the e-liquid tank to seal the bottom end of the e-liquid tank; the insulation ring comprises a second recess and is disposed on the bottom of the base to collect the e-liquid condensate. Thus, the leak-proof device has a double leak-proof effect.

The leak-proof device further comprises a heating wire, a strip of cotton, and a seal pad; the heating wire is nested in the strip of cotton to atomize absorbed e-liquid on the strip of cotton; the upper cover is disposed on the strip of cotton; the strip of cotton is disposed in the first recess of the base to absorb deposited e-liquid in the recess; the seal pad is disposed on the top part of the base to seal the e-liquid.

The disclosure also provides an electronic cigarette, comprising an atomization assembly and a battery assembly; the atomization assembly comprises the aforesaid leak-proof device.

The electronic cigarette further comprises an air guide module; the air guide module comprises a joint comprising an air inlet; when in use, the air enters the electronic cigarette via the air inlet, passes through an air passage, and is discharged from the top part of the atomization assembly.

The air guide module further comprises the insulation ring; the joint is disposed in the insulation ring for electric conduction and air conduction; the insulation ring is disposed in the base as a carrier of the joint.

The atomization assembly is disposed on one end of the battery assembly. The atomization assembly is connected to the battery assembly through the magnetic attraction between the magnet and the iron shell. The leak-proof device of the atomization assembly can absorb deposited e-liquid and collect e-liquid condensate, thereby prevent the deposited e-liquid or e-liquid condensate from flowing into the battery assembly, thus avoiding short circuit. The atomization assembly further comprises an air guide module. The air guide module comprises a joint comprising an air inlet. When in use, the air enters the electronic cigarette via the air inlet, passes through the air passage, and is discharged from the top part of the atomization assembly.

DETAILED DESCRIPTION

To further illustrate, embodiments detailing an electronic cigarette are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

As shown inFIGS.1-5, an electronic cigarette comprises an atomization assembly A and a battery assembly B. The atomization assembly is disposed on one end of the battery assembly B. The battery assembly comprises a magnet16and the atomization assembly comprises an iron shell12. The atomization assembly is connected to the battery assembly through the magnetic attraction between the magnet16and the iron shell12. Specifically, the atomization assembly A comprises an e-liquid tank1, a first seal ring2, an upper cover3, a heating wire4, a strip of cotton5, and a seal pad6, a base7, a second seal ring8, and an insulation ring9, a seal plug10, a joint11, and an iron shell12. The heating wire4is horizontally inserted in the strip of cotton5to atomize the absorbed e-liquid on the strip of cotton. The upper cover3is disposed on the strip of cotton5to isolate the e-liquid in the e-liquid tank1. The first seal ring2is disposed on the top end of the upper cover3to seal the internal air passage of the e-liquid tank1. The base7comprises a first recess. The strip of cotton5is disposed in the first recess of the base7to absorb deposited e-liquid in the recess. The seal pad6is disposed on the top part of the base7to seal the e-liquid. The second seal ring8is disposed on the base7; the base7is disposed on the bottom end of the e-liquid tank1to seal the bottom end of the e-liquid tank1. The insulation ring9comprises a second recess and is disposed on the bottom of the base7to collect e-liquid condensate. The joint11comprises an air inlet and is disposed in the insulation ring9for electric conduction and air conduction. As a carrier of the joint11, the insulation ring9is installed in the base7and communicates with the internal airway of the atomization assembly. The seal plug10is disposed on the bottom of the base7to seal the e-liquid injection hole of the base7. The iron shell12is disposed on the bottom of the e-liquid tank1.

The battery assembly B comprises a third seal ring13, an air column14, a spring contact15, a magnet16, a main support17, a silicone light guide18, a pneumatic switch19, a silicone gasket20, a battery21, a USB panel22, and a housing23. The third seal ring13is disposed on the main support17to prevent air leakage. The spring contact15is disposed on the top of the main support17for air conduction. The air column14runs through the top part of the main support17to support the internal air passage of the joint11of the atomization assembly. The silicone gasket20is disposed in the main support17. The upper part of the silicone gasket20is connected to the lower part of the air column14so as to drive the pneumatic switch19to work upon inhaling. The pneumatic switch19is disposed in the silicone gasket20and is fixed on the main support17. The silicone light guide18is disposed on the pneumatic switch19. The USB panel22is soldered to the pneumatic switch19and the pneumatic switch19is soldered to the battery so as to charge the battery21. The main support17is disposed in the housing23.

The atomization assembly is disposed on one end of the battery assembly. The atomization assembly is connected to the battery assembly through the magnetic attraction between the magnet and the iron shell. The leak-proof device of the atomization assembly can absorb deposited e-liquid and collect e-liquid condensate, thereby prevent the deposited e-liquid or e-liquid condensate from flowing into the battery assembly, thus avoiding short circuit. The atomization assembly further comprises an air guide module. The air guide module comprises the joint comprising an air inlet. When in use, the air enters the electronic cigarette via the air inlet, passes through the air passage, and is discharged from the top part of the atomization assembly.
