Electronic cigarette and mouthpiece part thereof

Abstract

The present invention relates to an electronic cigarette and mouthpiece part thereof. The mouthpiece part includes within an inhaling shell: an aerosol passage, a reservoir, an atomizing device, and a guiding device for sealing the reservoir and guiding tobacco substance from the reservoir to the atomizing device for vaporization without fluid leakage. The guiding device includes a guiding plate and an absorption piece laminating each other. Tobacco substance penetrates the guiding plate and is absorbed and stored in the absorption piece for vaporization. The electronic cigarette includes the mouthpiece part and a power source part connecting each other. The electronic cigarette and mouthpiece part thereof facilitate assembling, improve guiding tobacco substance, and prevent fluid-leakage.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation-in-part of U.S. application Ser. No. 13 / 502,124, filed Apr. 13, 2012, which is a national phase of PCT Application No. PCT / CN2012 / 073664 filed on Apr. 9, 2012, which claims benefit of Chinese Patent Application No. 201220141170.8, filed on Apr. 1, 2012, the disclosure of which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a kind of electronic cigarette and a mouthpiece part thereof.[0004]2. Description of Related Art[0005]A mouthpiece part of the existing electronic cigarette comprises in an opaque inhaling shell: a reservoir, an atomizing device with an electric heat wire and an atomizing cup, a long guiding tube for guiding tobacco substance from the reservoir to the atomizing device, and a mouthpiece cap at an end of the inhaling shell. Both ends of the electric heat wire are respectively associated with positive electrode and ...

AI Technical Summary

Benefits of technology

[0008]A main object of the present invention is to provide a mouthpiece part and an electronic cigarette, which facilitates assembly and manufacturing, and improves guiding tobacco substance, and prevents fluid-leakage.

[0010]To obtain the above object, a mouthpiece part of an electronic cigarette comprises an inhaling shell; within the inhaling shell, an aerosol passage, a reservoir for storing tobacco substance, an atomizing device which comprising an atomizing cup and an atomizer mounted in the atomizing cup, a guiding device set between the reservoir and atomizing device for sealing the reservoir and guiding tobacco substance from the reservoir to the atomizing cup for vaporization without fluid leakage. The guiding device comprises a guiding plate and an absorption piece laminating each other in such way that the guiding plate covers an open end of the reservoir and the absorption piece facing the atomizer in the atomizing cup. Thereby tobacco substance penetrates the guiding plate and is absorbed and stored in the absorption piece for vaporization.

Problems solved by technology

However, such mouthpiece part of the existing electronic cigarette with the guiding tube extending into the reservoir, has problems such as complicated and inconvenient assembly, fluid leaking, and uncontrollability of guiding tobacco substance.

Furthermore, the electric heat wire is pre-soldered or pre-fixed with conductive wires, and then is soldered to two electrodes of atomizing device, which results a miscellaneous and uneasy assembly process.

Moreover, the atomizing cup consists of many parts, which adds to the difficulties of assembling electric heat wire.

Finally, the inhaling shell is opaque, remaining tobacco substance in the reservoir is unobservable, which results unpleasant-flavor gas usually generated from burning electric heat wire after tobacco substance is exhausted.
