     Pursuant to 35 U.S.C. § 119 and the Paris Convention Treaty, this application claims foreign priority to Chinese Patent Application No. 201922292040.9 filed Dec. 18, 2019, the contents of which, including any intervening amendments thereto, are incorporated herein by reference. Inquiries from the public to applicants or assignees concerning this document or the related applications should be directed to: Matthias Scholl P. C., Attn.: Dr. Matthias Scholl Esq., 245 First Street, 18th Floor, Cambridge, Mass. 02142. 
     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 in  FIGS.  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 magnet  16  and the atomization assembly comprises an iron shell  12 . The atomization assembly is connected to the battery assembly through the magnetic attraction between the magnet  16  and the iron shell  12 . Specifically, the atomization assembly A comprises an e-liquid tank  1 , a first seal ring  2 , an upper cover  3 , a heating wire  4 , a strip of cotton  5 , and a seal pad  6 , a base  7 , a second seal ring  8 , and an insulation ring  9 , a seal plug  10 , a joint  11 , and an iron shell  12 . The heating wire  4  is horizontally inserted in the strip of cotton  5  to atomize the absorbed e-liquid on the strip of cotton. The upper cover  3  is disposed on the strip of cotton  5  to isolate the e-liquid in the e-liquid tank  1 . The first seal ring  2  is disposed on the top end of the upper cover  3  to seal the internal air passage of the e-liquid tank  1 . The base  7  comprises a first recess. The strip of cotton  5  is disposed in the first recess of the base  7  to absorb deposited e-liquid in the recess. The seal pad  6  is disposed on the top part of the base  7  to seal the e-liquid. The second seal ring  8  is disposed on the base  7 ; the base  7  is disposed on the bottom end of the e-liquid tank  1  to seal the bottom end of the e-liquid tank  1 . The insulation ring  9  comprises a second recess and is disposed on the bottom of the base  7  to collect e-liquid condensate. The joint  11  comprises an air inlet and is disposed in the insulation ring  9  for electric conduction and air conduction. As a carrier of the joint  11 , the insulation ring  9  is installed in the base  7  and communicates with the internal airway of the atomization assembly. The seal plug  10  is disposed on the bottom of the base  7  to seal the e-liquid injection hole of the base  7 . The iron shell  12  is disposed on the bottom of the e-liquid tank  1 . 
     The battery assembly B comprises a third seal ring  13 , an air column  14 , a spring contact  15 , a magnet  16 , a main support  17 , a silicone light guide  18 , a pneumatic switch  19 , a silicone gasket  20 , a battery  21 , a USB panel  22 , and a housing  23 . The third seal ring  13  is disposed on the main support  17  to prevent air leakage. The spring contact  15  is disposed on the top of the main support  17  for air conduction. The air column  14  runs through the top part of the main support  17  to support the internal air passage of the joint  11  of the atomization assembly. The silicone gasket  20  is disposed in the main support  17 . The upper part of the silicone gasket  20  is connected to the lower part of the air column  14  so as to drive the pneumatic switch  19  to work upon inhaling. The pneumatic switch  19  is disposed in the silicone gasket  20  and is fixed on the main support  17 . The silicone light guide  18  is disposed on the pneumatic switch  19 . The USB panel  22  is soldered to the pneumatic switch  19  and the pneumatic switch  19  is soldered to the battery so as to charge the battery  21 . The main support  17  is disposed in the housing  23 . 
     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. 
     It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
