     BACKGROUND 
     The disclosure relates to an electronic cigarette. 
     A conventional electronic cigarette includes an atomization assembly and a battery assembly. The atomization assembly includes no airflow regulator and the vapor volume of the electronic cigarette is unadjustable. 
     SUMMARY

     The atomizer further comprises an e-liquid tank equipped with an air passage, the airflow regulator is disposed in the air passage of the e-liquid tank; when in use, the air enters the atomizer from the air vent of the regulating ring, passes through the air passage of the e-liquid tank, flows into an internal air passage of the atomizer, and discharges out of the atomizer. 
     The air enters the atomizer from the air vent of the regulating ring, passes through the air passage of the e-liquid tank, flows into the internal air passage disposed on a bottom of the atomizer, thereby completing an internal circulation of the airflow, and discharges from a top opening of the e-liquid tank. 
     The atomizer further comprises an e-liquid injection hole disposed on the e-liquid tank and a seal plug disposed in the e-liquid injection hole; when in maintenance, the seal plug is pulled out from the e-liquid injection hole so as to inject the e-liquid into the e-liquid tank. 
     The airflow regulator is disposed in the air passage in an upper left of the e-liquid tank, and the e-liquid injection hole is disposed on an upper right of the e-liquid tank. 
     Also provided is an electronic cigarette, comprising an atomization assembly and a battery assembly; the atomization assembly comprises the aforesaid atomizer; the atomization assembly is disposed on the battery assembly and magnetically connected to the battery assembly through magnetic attraction of a first magnet and a second magnet. 
     With regard to the electronic cigarette, the atomization assembly is disposed on the battery assembly and magnetically connected to the battery assembly through magnetic attraction of the first magnet and the second magnet. The atomizer of the atomization assembly comprises the hollow cylinder and the airflow regulator disposed on the hollow cylinder, and the regulating ring is rotatable so as to control the vapor volume of the atomizer. The atomizer further comprises the e-liquid injection hole, and when in maintenance, the seal plug is pulled out from the e-liquid injection hole whereby the e-liquid is injected into the atomizer.

     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 , the disclosure provides an electronic cigarette comprising an atomization assembly A and a battery assembly B. The atomization assembly comprises an atomizer. 
     The atomizer comprises a hollow cylinder and an airflow regulator disposed on the hollow cylinder; the airflow regulator comprises a regulating ring  3 , a seal ring  4 , and a rod  5 ; the regulating ring  3  comprises an air vent; the regulating ring  3  is disposed on the rod  5 ; the seal ring  4  is disposed on the rod  5  and seals the regulating ring  3 ; and the regulating ring  3  is rotatable so as to control the vapor volume of the atomizer. 
     The airflow regulator is disposed on the upper left or the upper right of the atomizer. 
     The atomizer further comprises an e-liquid tank  6  equipped with an air passage, the airflow regulator is disposed in the air passage of the e-liquid tank; when in use, the air enters the atomizer from the air vent of the regulating ring  3 , passes through the air passage of the e-liquid tank  6 , flows into an internal air passage of the atomizer, and discharges out of the atomizer. 
     Specifically, the air enters the atomizer from the air vent of the regulating ring  3 , passes through the air passage of the e-liquid tank  6 , flows into the internal air passage disposed on a bottom of the atomizer, thereby completing an internal circulation of the airflow, and discharges from a top opening of the e-liquid tank  6 . 
     The atomizer further comprises an e-liquid injection hole disposed on the e-liquid tank  6  and a seal plug  2  disposed in the e-liquid injection hole; when in maintenance, the seal plug  2  is pulled out from the e-liquid injection hole so as to inject the e-liquid into the e-liquid tank  6 . 
     Specifically, the atomization assembly comprises a mouthpiece cover  1 , a seal plug  2 , a regulating ring  3 , a seal ring  4 , a rod  5 , an e-liquid tank  6 , an upper cover  7 , a first sealing gasket  8 , an atomizer  9 , a second sealing gasket  10 , a lower cover  11 , a third sealing gasket  12 , a first magnet  13 , and a joint  14 . The seal ring  4  is disposed on the rod  5  and seals the regulating ring  3 ; the regulating ring  3  is disposed on the rod  5  to form an airflow regulator. The airflow regulator is disposed in the air passage in the upper left of the e-liquid tank  6 ; the seal plug  2  is disposed in the e-liquid injection hole on the upper right of the e-liquid tank  6 .
