The invention is applicable to the field of electronic cigarettes, and provides an
electronic cigarette capable of discharging
tar by means of suction of consumers, which comprises a
tar cup component, tobacco
tar, a heating wire component, a tar separating sheet, tar storage cotton, a tar cup bottom cover, a tar filling cover, a pneumatic switch sleeve, a pneumatic switch, a PCB (
printed circuit board) support, a PCB, a
lithium battery and a base. During smoking, the pneumatic switch is turned on through
suction force, a circuit is connected, heating is performed to generate atomization, the
suction force of a
consumer can open a thin film formed by the oil inlet hole and the oil outlet hole of the
oil separation piece, and tobacco tar in the oil bin of the oil cup
assembly flows into the empty bin of the
oil separation piece through the oil inlet hole of the
oil separation piece, flows into the
oil storage cotton through the oil outlet hole of the oil separation piece and then is heated and atomized; when the cigarette is not smoked, the power is
cut off, the cigarette oil is not absorbed, the oil inlet hole and the oil outlet hole of the oil separation piece are closed, the cigarette oil in the oil bin of the oil cup
assembly is separated from the cigarette oil in the
oil storage cotton, and the cigarette oil cannot be absorbed when the cigarette is smoked again. According to the
electronic cigarette, the oil cup can be made of the transparent material, so that a user does not need to worry about
dry mouth caused by no oil during smoking.
