ELECTRONIC CIGARETTE
An electronic cigarette is provided, comprising: a suction nozzle cover, wherein, a surface of the suction nozzle cover corresponding to a mouth cavity of a user of the electronic cigarette is concave. In the electronic cigarette of the present invention, because the suction nozzle cover includes a buffering function of concave, when the two sides of the suction nozzle cover are pressed and/or squeezed by the radial force, and the suction nozzle cover generates a tendency of motion to inside body, thereby the suction nozzle cover is prevented from falling off from the electronic cigarette; furthermore, the user will feel more flexible when using the electronic cigarette with that structure, and user's experience is improved; moreover, it can avoid sucking the tobacco oil when a little tobacco oil flows from the suction inlet.
1 . An electronic cigarette, comprising a suction nozzle cover, wherein, a surface of the suction nozzle cover corresponding to a mouth cavity of a user of the electronic cigarette is concave.
2 . The electronic cigarette according to claim 1 , wherein, a section of the concave is any one of an arc-shaped groove, a rectangular groove, a V-groove, a W-groove, and a trapezoid groove.
3 . The electronic cigarette according to claim 1 , wherein, the suction nozzle cover includes a hollow body, a first end and a second end, the second end recesses inward to form the concave, and the second end defines at least one suction inlet therein; when the suction nozzle cover is pressed or squeezed by a radial external force, an inward force along the axis of the second end is greater than an outward force along the axis of the second end.
4 . The electronic cigarette according to claim 3 , wherein, the electronic cigarette further comprises an outer sleeve, the body is sleeved inside the outer sleeve, and the first end is mounted on the outer sleeve.
5 . The electronic cigarette according to claim 2 , wherein, the trapezoid groove is an isosceles trapezoid groove.
6 . The electronic cigarette according to claim 5 , wherein, an angle formed by a side edge of the isosceles trapezoid groove and a center axis of the outer sleeve is 10°˜40°.
