     BACKGROUND 
     The disclosure relates to an electronic cigarette. 
     Electronic cigarettes atomize nicotine-containing e-liquid. A conventional cartomizer of the electronic cigarettes cannot be refilled with e-liquid. The atomizer is integrated with the cartomizer and cannot be replaced with a new one. 
     SUMMARY 
     The disclosure provides an electronic cigarette comprising an atomization assembly and a battery assembly. The atomization assembly is disposed on the battery assembly. The atomization assembly comprises a rotatable ring disposed on one end of the atomization assembly; the rotatable ring is configured to adjust a volume of air and vapor of the electronic cigarette; the atomization assembly further comprises a refillable cartomizer, an atomizer, and a silicone base disposed on one end of the refillable cartomizer; and the atomizer is in pluggable connection to the silicone base. 
     The atomization assembly further comprises a second silicone seal, a second support base, a third seal ring, and a base; the second silicone seal is disposed on the second support base; the third seal ring is disposed on the second support base to seal the rotatable ring; the rotatable ring is disposed on the second support base; the base is fixed on the second support base to fix the rotatable ring; the rotatable ring comprises a side wall provided with an air hole corresponding to an air vent of the second support base; when in use, the volume of air and vapor of the electronic cigarette is adjustable upon the rotation of the rotatable ring. 
     The refillable cartomizer comprises a seal plug, an e-liquid storage tank, a silicone base, a first silicone seal, and a steel casing; the seal plug is disposed on a top end of the e-liquid storage tank; the silicone base is disposed on a bottom end of the e-liquid storage tank; the first silicone seal is disposed on a top end of the atomizer; the silicone base is disposed around the atomizer; the atomizer is disposed in the e-liquid storage tank; and the steel casing is disposed on the bottom end of the e-liquid storage tank. 
     The rotatable ring is disposed on one end of the atomization assembly to adjust the volume of air and vapor of the electronic cigarette. The cartomizer of the atomization assembly can be refilled with e-liquid and thus can be used repeatedly. The atomizer can be directly pulled out from the silicone base at the bottom of the cartomizer, so that the atomizer is easily replaced when the atomizer breaks down.

     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 comprises a mouthpiece  1 , a first seal ring  2 , a first support base  3 , a second seal ring  4 , a seal plug  5 , an e-liquid storage tank  6 , a silicone base  7 , a first silicone seal  8 , a steel casing  9 , an atomizer  10 , an observation tube  11 , a second silicone seal  12 , a second support base  13 , a third seal ring  14 , a rotatable ring  15 , a base  16 , an insulation ring  17 , and a joint  18 . The first seal ring  2  is disposed on the mouthpiece  1 , and the mouthpiece  1  is disposed on the first support base  3 . The second seal ring  4  is wrapped around the first support base  3 . The first support base  3  is disposed on the top of the observation tube  11 . The seal plug  5  is disposed on the e-liquid storage tank  6 . The silicone base  7  and the steel casing  9  are disposed on the bottom part of the e-liquid storage tank  6 . The first silicone seal  8  is disposed in the atomizer  10 , and the atomizer  10  is disposed on the silicone base  7 . The e-liquid storage tank  6  is disposed in the observation tube  11 . The insulation ring  17  and the joint  18  are consecutively disposed on the base  16 . The base  16  is connected to the second support base  13 . The second silicone seal  12  and the third seal ring  14  are disposed on the top and the side of the second support base  13 , respectively. The rotatable ring  15  is wrapped around the second support base  13  and disposed on the bottom part of the observation tube  11 . Specifically, the seal plug  5  is disposed on the e-liquid storage tank  6 ; the silicone base  7  and the steel casing  9  are disposed on the bottom part of the e-liquid storage tank  6 ; the first silicone seal  8  is disposed in the atomizer  10 , and the atomizer  10  is disposed on the silicone base  7 , whereby a cartomizer is formed. The rotatable ring  15  is disposed on one end of the atomization assembly to adjust the volume of air and vapor of the electronic cigarette. The cartomizer of the atomization assembly can be refilled with e-liquid and thus can be used repeatedly. The seal plug  5  of the cartomizer is a long strip, and the neck of the seal plug is easy to be pulled off thus simplifying the installation thereof. Thus, the seal plug is easily installed on the cartomizer to block the e-liquid inlet. The atomizer  10  can be directly pulled out from the silicone base  7  at the bottom of the cartomizer, so that the atomizer is easily replaced when the atomizer breaks down. 
     The battery assembly B comprises an electrode  19 , an electrode insulator  20 , a fourth seal ring  21 , a threaded ring  22 , a fastener  23 , a button  24 , a support  25 , a control panel  26 , a silicone button  27 , a first ethyl vinyl acetate (EVA) pad  28 , a battery cell  29 , a cartridge  30 , a second EVA pad  31 , and a bottom cover  32 . The control panel  26  is disposed on the fastener  23 , and the fastener  23  is disposed on the support  25 . The silicone button  27  is disposed on the button  24  and the button  24  is disposed on the support  25 . The battery cell  29  is disposed on the control panel  26 . The first ethyl vinyl acetate (EVA) pad  28  and the second EVA pad  31  are disposed on two ends of the electrodes of the battery cell  29 . The battery cell  29  is disposed on the cartridge  30 . The bottom cover  32  is disposed on one end of the cartridge  30 . The electrode insulator  20  and the electrode  19  are consecutively disposed in the threaded ring  22 . The fourth seal ring  21  is disposed around the threaded ring  22 . The threaded ring  22  is disposed on the top of the cartridge  30 . The atomization assembly A is disposed on the battery assembly B. The base  16  of the atomization assembly A is in threaded connection to the threaded ring  22  of the battery assembly B. 
     The following advantages are associated with the electronic cigarette of the disclosure. The rotatable ring is disposed on one end of the atomization assembly to adjust the volume of air and vapor of the electronic cigarette. The cartomizer of the atomization assembly can be refilled with e-liquid and thus can be used repeatedly. The seal plug of the cartomizer is a long strip, and the neck of the seal plug is easy to be pulled off thus simplifying the installation thereof. Thus, the seal plug is easily installed on the cartomizer to block the e-liquid inlet. The atomizer can be directly pulled out from the silicone base at the bottom of the cartomizer, so that the atomizer is easily replaced when the atomizer breaks down. 
     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.
