Abstract

The invention provides an electronic cigarette vaporizer, comprising a housing, a mouthpiece connected with an end of the housing and provided with a vapor channel, and a threaded connecting end sleeve-connected with another end of the housing, wherein the mouthpiece is dismountably connected with an end of the housing, an outer sleeve is closely sleeved in the housing, an inner sleeve is arranged within the outer sleeve, a closed liquid storage chamber for storing cigarette liquid is formed between the outer sleeve, the inner sleeve, the mouthpiece, and the threaded connecting end. The invention has advantages that, when the cigarette liquid is used up and the mouthpiece is dismounted, the chamber body of the liquid storage chamber can be opened to facilitate the replenishment of cigarette liquid and the reuse of the electronic cigarette vaporizer by the user.

Claims
