  2. The electronic cigarette of claim 1, wherein the atomization assembly further comprises a second silicone seal (12), a second support base (13), a third seal ring (14), and a base (16); the second silicone seal (12) is disposed on the second support base (13); the third seal ring (14) is disposed on the second support base (13) to seal the rotatable ring (15); the rotatable ring (15) is disposed on the second support base (13); the base (16) is fixed on the second support base (13) to fix the rotatable ring (15); the rotatable ring (15) comprises a side wall provided with an air hole corresponding to an air vent of the second support base (13); when in use, the volume of air and vapor of the electronic cigarette is adjustable upon the rotation of the rotatable ring (15).

Description

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. In some conventional electronic cigarettes, a thin seal ring is employed to seal the gap between the base and the oil storage tank. For example, CN 108634385 A recites an electronic cigarette containing a glass tube for storing oil, a base pressing member, and a sealing ring. The base pressing member is fixed to the glass tube only via the sealing ring. A silicone ring is attached between the bottom end of a heating wire limit cover and the base pressing member. An electronic cigarette according to the present invention is defined in claim 1. 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, a steel casing, and an atomizer; 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.
