Electronic cigarette

1. An electronic cigarette comprising a cigarette body, an atomizing assembly, a switching controlling module and a battery assembly; the atomizing assembly, the switching controlling module and the battery assembly being housed in the cigarette body; and

wherein a switching key is defined on a surface of the cigarette body; emitting material being indicated the position of the switching key is configured on the cigarette body;

wherein the emitting material is a noctilucent material, which is configured around the switching key;

wherein the switching controlling module comprises a PCB board and a switching base; the switching key is pressed to contact or connect the switching base; the switching base is configured for transmitting a press signal from the switching key to the PCB board, thus the PCB board controls electric connection between the atomizing assembly and the battery assembly;

wherein a suction mouth lid is mounted at an end of the cigarette body, and the suction mouth lid contains a suction part and a fixing part; the fixing part is close to the cigarette body, emitting material is configured on the fixing part, and a light transmission layer is added on the emitting material of the fixing part;

wherein a light cap is made of emitting material and is mounted at the other end which is away from the suction mouth lid of the cigarette body;

wherein emitting material in granular shape is embedded into an outer surface of the light cap; an emitting layer is formed by the emitting material in granular shape;

wherein a grain of the emitting material in granular shape has a volume of 1.5 mm 3 to 150 mm 3 , and distance between adjacent grains is 0.5 mm to 3 mm; and

wherein a transparent layer used for light transmission is mounted on the emitting layer and the transparent layer is resin.
