Electronic cigarette

Abstract

Disclosed is an electronic cigarette (100), comprising a cylinder housing (1), and a liquid storage component (37) and an atomizer (21) provided in the housing (1), wherein an end of the housing (1) is provided with a suction nozzle cover assembly (4, 4′, 4″) for suction by a smoker, the suction nozzle cover assembly (4, 4′, 4″) comprises a suction nozzle primary cover (41, 41″) and a suction nozzle secondary cover (42, 42′, 42″) cooperating with the suction nozzle primary cover (41, 41″), the suction nozzle primary cover (41, 41″) is inserted into the housing (1) and fixed to an inner wall of the housing (1), the suction nozzle secondary cover (42, 42′) is inserted into and fixed to the suction nozzle primary cover (41) and alternatively, the suction nozzle secondary cover (42″) is inserted and fixed to the inner wall of the housing (1), a cooling cavity is formed between the suction nozzle primary cover (41, 41″) and the suction nozzle secondary cover (42, 42′, 42″), and both the suction nozzle primary cover (41, 41″) and the suction nozzle secondary cover (42, 42′, 42″) are provided with a ventilation hole (412, 421, 421′, 412″, 412″) in communication with the cooling cavity. This electronic cigarette can reduce or avoid the possibility of a smoker inhaling cigarette liquid, and improve the safety of use.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of electronic cigarette.BACKGROUND OF THE INVENTION[0002]Existing electronic cigarette typically includes a cylindrical shaped casing, inside of the casing is equipped with a tobacco-liquid cup for holding tobacco-liquid, an atomizer for atomizing the tobacco-liquid to smoke, and a storage power source for supplying power for the atomizer. A part of the casing is provided with a mouthpiece cover for sucking by smokers, the number of the mouthpiece cover is only one and the thickness of the inner-wall thereof is relatively thin. Since smoke flows out of the electronic cigarette via the mouthpiece cover from the inner of the electronic cigarette, some fine particles of the tobacco-liquid included in the smoke will be sucked into the mouths of the smokers directly, thus a phenomenon that the smokers suck in tobacco-liquid occurs. Moreover, due to the relatively thin wall thickness or the single-wall design of the in...

AI Technical Summary

Benefits of technology

[0003]The object of the present invention is to provide an electronic cigarette, which can reduce or avoid the inhaling of the tobacco-liquid by smokers, and improve safety in utilization.

[0012]Wherein the mouthpiece main cover and the mouthpiece vice cover are both made from plastic material with good heat insulation effect.

[0018]By adopting the above embodiments, the present invention has the following advantages: first, the formation of a cooling cavity between the mouthpiece main cover and the mouthpiece vice cover of the mouthpiece component allows for the fine tobacco-liquid particles contained in the smoke naturally cooling and condensing on the inner wall of the cooling cavity, which can reduce or avoid inhaling of the tobacco-liquid by smokers. Secondly, while smoke flowing through the mouthpiece component, the heat exchanged between the smoke and the mouthpiece component is absorbed by the mouthpiece main cover and the mouthpiece vice cover as a share, such that the temperatures of the mouthpiece main cover and the mouthpiece vice cover are relatively low, which can avoid burning or scalding the mouth of the smoker and improve the utilization safety of the electronic cigarette. In addition, a closed space for storing the tobacco-liquid is formed by the mouthpiece cover, the liquid isolating member and a part of the casing together, replacing the conventional tobacco-liquid cup. The liquid-storage member is accommodated within the closed space and the inner structure is simple, which makes the assembly and disassembly of the electronic cigarette convenient and quick.

Problems solved by technology

Moreover, due to the relatively thin wall thickness or the single-wall design of the inner wall of the mouthpiece cover, hot smoke will transfer heat with the mouthpiece cover when flowing through the mouthpiece cover, which leads to a continuous increasing of the mouthpiece temperature, exhibits a potential safety hazard of the mouths of smokers being burnt.

In addition, because the tobacco-liquid cup is provided with components such as a cup seat, an atomizer seat etc. inside, this complex inner structure results in time-consuming and inconvenient during assembly and disassembly.
