Abstract

A suction nozzle cover and an electronic cigarette. The electronic cigarette includes a tube and a suction nozzle cover. The suction nozzle cover includes a cap and a cover body which extends along a lower surface of the cap. An annular platform is formed by the cap with respect to a periphery of the cover body. A lateral wall of the annular platform is at least provided with one first suction outlet, a lateral wall of the cover body is at least provided with one first groove, and the first groove and the suction outlet are connected to each other to form a channel for smoke extraction.

Claims

1. An electronic cigarette comprising a tube and a suction nozzle cover, wherein the suction nozzle cover comprises a cap and a cover body which extends along a lower surface of the cap;

wherein an annular platform is formed by the cap with respect to a periphery of the cover body;

a lateral wall of the annular platform is provided with four suction outlets uniformly distributed thereon, a total area of the suction outlets is between two square millimeters and six square millimeters;
