     The battery assembly further comprises a rotatable fixed seat, an insulation tube, an LED tube, a bolt, a decorative board, a battery, a control panel, a rubber ring, a support, and a battery case. The electrode pair is disposed on the support to supply power to the atomization assembly. The rubber ring is disposed on the support to insulate the electrode pair. The insulation tube is disposed on the top end of the rotating shaft. The rotatable fixed seat is disposed on the insulation tube to fix the rotating shaft. The switching PCB is disposed on the rotatable fixed seat and is connected to the rotating shaft. The LED tube is disposed on the bottom end of the rotating shaft. The rotating shaft is disposed in the support. The battery is soldered on the control panel and the control panel is fixed on the support. The support is disposed in the battery case. The bottom casing is disposed on the bottom end of the battery case, in contact with the LED tube to connect to and control the rotating shaft. The bolt is in threaded connection to the bottom end of the bottom casing. The LED tube is fixed in the bottom casing. The decorative board is attached to a bottom surface of the bottom casing; and the magnet is disposed on the top end of the support. 
     The atomization assembly comprises an atomizer and an e-liquid tank. The atomizer comprises two or more heating elements. The e-liquid tank comprises a plurality of compartments corresponding to the heating elements in number; and the two or more heating elements are disposed in the plurality of compartments, respectively. The plurality of compartments is filled with different e-liquid materials. The users can switch the working mode of the atomizer to vaporize different e-liquid materials.

     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. 
     In the disclosure, smoke materials refer to smoke oil, tobacco, tobacco and other materials used to produce smoke. 
     As shown in  FIGS. 1-5 , an electronic cigarette comprises two heating elements and an e-liquid tank  3  comprising two compartments. Specifically, the electronic cigarette comprises an atomization assembly A and a battery assembly B. The atomization assembly A a mouthpiece  1 , a seal plug  2 , an e-liquid tank  3 , an atomizer  4 , a rubber gasket  5 , a bottom cover  6 , a joint  7 , and a magnet  8 . The atomizer  4  is disposed on the rubber gasket  5 . The rubber gasket  5  is disposed on the bottom cover  6 . The joint  7  is disposed on the bottom end of the bottom cover  6  to fix the atomizer  4 . The bottom cover  6  is disposed on a bottom part of the e-liquid tank  3  to seal the e-liquid tank. The seal plug  2  is disposed on the top part of the e-liquid tank  3  to seal an e-liquid injection hole of the e-liquid tank; and the mouthpiece  1  is disposed on the top end of the e-liquid tank  3 .
