Abstract

The present disclosure discloses an electronic cigarette. The electronic cigarette includes a cigarette pipe having a cavity, an atomizer device received in the cavity and a cartridge detachably mounted to the atomizer device. The atomizer device is provided with a heating element. The cartridge includes a main body inserted in the cavity, a channel extending through the main body, an e-liquid storage member detachably installed in the main body, and an e-liquid carrier. The channel is in communication with the outside. The e-liquid carrier is received in the channel. The e-liquid carrier is capable of absorbing e-liquid in the e-liquid storage member. The heating element includes a heating end extending into the e-liquid carrier.
