     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 - 6   , an electronic cigarette comprises an atomization assembly A and a battery assembly B. The atomization assembly is disposed on the battery assembly. The atomization assembly A comprises an e-liquid storage tank  2  and a limit cover  4  disposed in the e-liquid storage tank  2 , and the limit cover comprises an air intake and an air passage. The e-liquid storage tank  2  comprises a side wall, a vertical air passage disposed along the side wall, and a bottom air passage communicating with the vertical air passage and the air intake of the limit cover; and the side wall comprises an air inlet communicating with the vertical air passage. When in use, air enters the atomization assembly via the air inlet, sinks along the vertical air passage and enters the bottom air passage of the atomization assembly, passes through the air intake of the limit cover  4 , flows upwards in the air passage of the limit cover  4 , and discharges from the top part of the atomization assembly. 
     In this way, the vertical air passage is disposed on one side of the atomizer assembly. The airflow enters the vertical air passage from one side of the atomizer assembly, sinks to the bottom of the atomizer assembly, flows upwards in the air passage of the limit cover  4 , and discharges from the top part of the atomization assembly. The entire air passage is a U-shaped structure, and can prevent the leakage of the e-liquid. 
     The atomization assembly further comprises a memory foam  5 , a heating wire  6 , and a fixed seat  7 ; the memory foam  5  is wrapped around the heating wire  6  and disposed in the fixed seat  7 . Preferably, the heating wire  6  is horizontally disposed in the memory foam  5 . More preferably, the atomization assembly further comprises a gasket seal  8 ; and the fixed seat  7  is disposed on the gasket seal  8 . 
     The memory foam of the atomization assembly can absorb the condensate at the upper end and the e-liquid deposited on the lower end of the atomization assembly, and the absorbed condensed e-liquid can be reused for the heating wire. 
     As an improvement, the battery assembly comprises a control panel  21  and a silicone pad  17 ; the control panel  21  is provided with a pneumatic switch disposed in the silicone pad  17 ; the silicone pad  17  comprises a curve air passage connected to the pneumatic switch; when in use, the air flows through the curve air passage to drive the pneumatic switch to work. 
     Specifically, the electronic cigarette comprises a plug  1 , an e-liquid storage tank  2 , a seal ring  3 , a limit cover  4 , a memory foam  5 , a heating wire  6 , a fixed seat  7 , a gasket seal  8 , a basal seat  9 , an insulation ring  10 , a first magnet  11 , a joint  12 , and a seal plug  13 . 
     The plug  1  is disposed on the top part of the e-liquid storage tank  2 . The heating wire  6  is horizontally disposed in the memory foam  5 , and the memory foam  5  is wrapped around the heating wire  6 . The memory foam  5  is disposed in the fixed seat  7 . The fixed seat  7  is disposed on the gasket seal  8 . The gasket seal  8  is disposed on the basal seat  9 . The insulation ring  10  is disposed in the basal seat  9 . The joint  12  is disposed in the insulation ring  10 . The seal ring  3  is wrapped around the limit cover  4 . The limit cover  4  is disposed on the top part of the fixed seat to fix the memory foam  5 . The basal seat  9  is disposed on one end of the e-liquid storage tank  2 . The first magnet  11  and the seal plug  13  are disposed in the basal seat  9 . 
     The vertical air passage is disposed on one side of the e-liquid storage tank  2 . The airflow enters the vertical air passage from one side of the e-liquid storage tank  2 , sinks to the bottom of the atomizer assembly, flows upwards in the air passage of the limit cover  4 , and discharges from the top part of the atomization assembly. The entire air passage is a U-shaped structure, and the condensate e-liquid cannot flow out of the e-liquid storage tank  2 , thus preventing the leakage of the e-liquid. 
     The battery assembly B comprises a second magnet  14 , a spring pin  15 , a light guide column  16 , a silicone ring  17 , a battery cell  18 , a support  19 , a baffle  20 , a control panel  21 , and a shell  22 . The second magnet  14 , the spring pin  15 , and the silicone ring  17  are disposed on the top part of the support  19 . The positive and negative electrodes of the control panel  21  are welded to the spring pin  15 , and the input end positive and negative electrodes are welded to the battery cell  18 . The battery cell  18  is disposed in the support  19  and fixed by the baffle  20 . The support  19  is disposed in the shell  22 . The atomization assembly is connected to the battery assembly through the magnetic attraction of the first magnet and the second magnet. 
     The following advantages are associated with the electronic cigarette of the disclosure: 
     1. the vertical air passage is disposed on one side of the atomizer assembly. The airflow enters the vertical air passage from one side of the atomizer assembly, sinks to the bottom of the atomizer assembly, flows upwards in the air passage of the limit cover, and discharges from the top part of the atomization assembly. The entire air passage is a U-shaped structure, and can prevent the leakage of the e-liquid. 
     2. The memory foam of the atomization assembly can absorb the condensate at the upper end and the e-liquid deposited on the lower end of the atomization assembly, and the absorbed condensed e-liquid can be reused for the heating wire. 
     3. The silicone pad comprises a curve air passage connected to the pneumatic switch; when in use, the air flows through the curve air passage to drive the pneumatic switch to work. 
     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.
