The present disclosure relates to a disposable electronic cigarette. The disposable electronic cigarette includes a housing (1), a battery assembly (2) and an atomization device (3). The housing (1) is hollow, and defines openings at two opposite ends. The battery assembly (2) and the atomization device (3) are connected, and disposed inside the housing (1). The atomization device (3) includes a liquid absorption member (31), a glass fiber tube (32), an electrical heating component (33) and a liquid stopper (34). The electrical heating component (3) further includes a heating wire (331) and a liquid-conducting core (332). The battery assembly (2) includes a cell core (21), a controller (22) and an LED lamp (23). A lampshade (5) is provided on a first end of the housing (1), and a mouthpiece cover (4) is arranged at a second end of the housing (1). The beneficial effects are that the battery assembly and atomization device are provided inside the housing to form one piece, avoiding assembling before smoking. Wire holes fixe the electrical heating component. The electrical heating component heats the tobacco liquid inside the atomization device. A hollow protruding rod facilitates the flow of the air, making the smoking smoother. The controller controls the electrical communication of the circuit of the battery assembly, the operation of the electronic heating element, and the LED lamps emission of light simulating smoking flames.
