Electronic cigarette and mouthpiece cover thereof

Abstract

An electronic cigarette and a mouthpiece cover. The electronic cigarette includes an e-liquid cup and an atomizer all disposed in an inhalation rod sleeve. The e-liquid cup includes a liquid-storage member, an e-liquid guiding tube, and an air-guiding tube in the liquid-guiding tube, and a mouthpiece cover. The mouthpiece cover is a solid body with at least one ventilation groove on a peripheral sidewall. Two ends of the ventilation groove are open, and respectively locate at two end surfaces. The ventilation groove is communicated with the air-guiding tube. The electronic cigarette provides an entirely new way of ventilation for the mouthpiece cover. The atomized e-liquid enters into human mouth through the ventilation groove at the periphery of the mouthpiece cover, may avoid the atomized e-liquid straight entering into the human mouth.
