    Description


    [0001] The disclosure relates to an electronic cigarette.

    [0002] Electronic cigarettes atomize nicotine-containing e-liquid.

    [0003] Conventionally, the atomizing unit and the battery are disposed in one cavity. This leads to the risk of the e-liquid coming into direct contact with the battery. CN 109 330 029 A shows an example of electronic cigarette with an alternative arrangement of the atomizing unit and the battery.

    [0004] The present invention provides an electronic cigarette according to claim 1.

    [0005] The electronic cigarette comprises a mouthpiece cover; a housing; a battery; a silicone seal; a limit cover; a heating wire; a seat fixing the heating wire; a drain tube; an e-liquid filling pipe; a silicone sleeve; a plate comprising a pneumatic switch; and an end cover.

    [0006] The mouthpiece cover is disposed on the housing; the heating wire is fixed on the seat; the heating wire comprises a pin which extends into the drain tube; the silicone seal sleeves the limit cover; the limit cover comprises a groove and the heating wire is embedded in the groove; the limit cover is disposed on the seat; the drain tube and the e-liquid filling pipe are disposed in the seat; the pin of the heating wire is fixed on the plate; the plate comprises a cathode and an anode which are connected to the battery; the silicone sleeve sleeves the plate; the silicone sleeve and the plate are disposed in the end cover; the end cover comprises a groove, and one end of the drain tube extends into the groove.

    [0007] In nonuse of the electronic cigarette, the condensed e-liquid can flow along the drain tube into the groove of the end cover, thus preventing the e-liquid from penetrating to the battery and the pneumatic switch of the plate, and avoiding the occurrence of the short circuit.

    FIG. 1 is an exploded view of an electronic cigarette according to one embodiment of the disclosure;

    FIG. 2 is a schematic diagram of an electronic cigarette according to one embodiment of the disclosure; and

    FIG. 3 is a sectional view of an electronic cigarette according to one embodiment of the disclosure.



    [0008] To further illustrate, embodiments detailing an electronic cigarette are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

    [0009] An electronic cigarette comprises a mouthpiece cover 1; a housing 2; a battery 3; a silicone seal 4; a limit cover 5; a heating wire 6; a seat 7 fixing the heating wire; a drain tube 8; an e-liquid filling pipe 9; a silicone sleeve 10; a plate 11 comprising a pneumatic switch; and an end cover 12.

    [0010] The mouthpiece cover 1 is disposed on the housing 2; the heating wire 6 is fixed on the seat 7; the heating wire 6 comprises a pin which extends into the drain tube 8; the silicone seal 4 sleeves the limit cover 5; the limit cover 5 comprises a groove and the heating wire 6 is embedded in the groove; the limit cover 5 is disposed on the seat 7; the drain tube 8 and the e-liquid filling pipe 9 are disposed in the seat 7; the pin of the heating wire 6 is fixed on the plate 11; the plate 11 comprises a cathode and an anode which are connected to the battery 3; the silicone sleeve 10 sleeves the plate 11; the silicone sleeve 10 and the plate 11 are disposed in the end cover 12; the end cover 12 comprises a groove, and one end of the drain tube extends into the groove.

    [0011] In nonuse of the electronic cigarette, the condensed e-liquid can flow along the drain tube into the groove of the end cover, thus preventing the e-liquid from penetrating to the battery and the pneumatic switch of the plate, and avoiding the occurrence of the short circuit.
