Abstract
The present disclosure discloses an electronic cigarette including a main body and an atomizer. The atomizer is adapted for being detachably mounted to a cartridge. The cartridge includes a containing cavity for storing e-liquid and a sealing film for sealing the containing cavity. The atomizer is provided with a first guide tube, a second guide tube and a heating tube connecting the first guide tube and the second guide tube. The atomizer includes a first end portion and a second end portion at a front end of the atomizer in order to pierce the sealing film. With this configuration, when the cartridge is used up, only a new cartridge needs to be replaced and the atomizer does not need to be scrapped together for saving cost.
