Abstract

The present disclosure relates to a disposable electronic cigarette. The disposable electronic cigarette includes a housing, a battery assembly and an atomization device. The housing is hollow, and defines openings at two opposite ends. The battery assembly and the atomization device are connected, and disposed inside the housing. The atomization device includes a liquid absorption member, a glass fiber tube, an electrical heating component and a liquid stopper. The electrical heating component further includes a heating wire and a liquid-conducting core. The battery assembly includes a cell core, a controller and an LED lamp. A lampshade is provided on a first end of the housing, and a mouthpiece cover is arranged at a second end of the housing. The beneficial effects are that the battery assembly and atomization device are provided inside the housing to form one piece, avoiding assembling before smoking.
