Abstract
Embodiments of the present disclosure disclose a high-comfort electronic cigarette mouthpiece. A center of the mouthpiece is provided with a vent penetrating through the mouthpiece. Two ends of the mouthpiece are respectively an air inlet end and an air outlet end, and the cross-section of the mouthpiece gradually decreases from the air inlet end to the air outlet end in a streamlined manner, which is of a date-pit shape, an eye shape, or an oval shape that is pointed at two side portions and bulging in a middle portion. In the embodiments of the present disclosure, the high-comfort electronic cigarette mouthpiece is designed to be of a streamlined shape that is pointed at two side portions and bulging in the middle portion, so that the mouthpiece perfectly matches a gap between closed upper and lower lips, thereby avoiding air leakage as a result of the gap between the upper and lower lips. Moreover, a protruding structure is disposed to further seal a gap between a side around the mouthpiece and the upper and lower lips, thereby improving air tightness between the mouthpiece and the lips.
