Abstract:
1. A mouthpiece device of an electronic cigarette comprising an inhaling shell, an atomizing device within the inhaling shell for vaporizing tobacco liquid into aerosol, a liquid-guiding tube, a stopper, a cap, and a connection element; wherein both ends of the inhaling shell are open, one of the open end of the inhaling shell is used as a connecting end for connection with a power supply part of the electronic cigarette, the other open end is used as an inhaling end for user's suction and is covered with the cap; the inhaling shell longitudinally forms a liquid reservoir and an aerosol passage side by side within the inhaling shell, first ends as inner ends of both the liquid reservoir and the aerosol passage are open and facing the atomizing device, and second ends of both the liquid reservoir and the aerosol passage are facing the inhaling end of the inhaling shell; tobacco liquid is sealed in the liquid reservoir; the stopper seals the inner end of the reservoir; the liquid-guiding tube is inserted through the stopper and guides tobacco liquid from the reservoir into the atomizing device; the cap defines a suction hole therethrough for passing aerosol from the second end of the aerosol passage to outside of the inhaling end for user's suction, and the cap is inserted at the inhaling end of the inhaling shell and removably seals the second end of the reservoir; the connection element as an electrode of the atomizing device is inserted in the connecting end of the inhaling shell and defines a cylindrical chamber therein for receiving the atomizing device; the atomizing device comprising an atomizing cup and an atomizer; the atomizing cup is an integrated and inseparable cup body made from silica gel in one mould, has a cylindrical shape in a diameter larger than that of the cylindrical chamber of connection element, and is tightly fitted in the connection element; the atomizing cup defines an atomizing chamber therein facing and communicating with the inner ends of both the liquid reservoir and the aerosol passage, and comprises a mounting seat integrally and inseparably extending away from a bottom of the atomizing chamber for a preset distance to engage with the atomizer in the atomizing chamber; wherein said cap defines an air slot for depositing tobacco particles on surface thereof, the air slot is communicated with the aerosol passage, and the suction hole is also communicated with the aerosol passage and is used for air communicating between inside and outside of the inhaling shell, wherein said air slot is stepped and shaped as letter Z, and the stepped air slot is communicated with the suction hole, the aerosol passage is communicated with the suction hole through the stepped air slot.
