COTTON-FREE ELECTRONIC CIGARETTE, HEAT-INSULATING AND HEAT-DISSIPATING COMPONENT OF VAPORIZER DEVICE, AND METHOD FOR HEAT INSULATION AND HEAT DISSIPATION
Disclosed is a cotton-free electronic cigarette, a heat-insulating and heat-dissipating component of a vaporizer device of the cotton-free electronic cigarette, and a method for heat insulation and heat dissipation. The heat-insulating and heat-dissipating component consists of a heat insulation sleeve and a vapor flow passage. The heat insulation sleeve is provided inside an outer pipe and outside a vaporizer unit. The heat insulation sleeve, the outer pipe and the vaporizer unit have a same central longitudinal axis. A method for heat insulation and heat dissipation of the cotton-free electronic cigarette comprises: dissipating heat generated from the vaporizer unit along the vapor flow passage formed between an exterior longitudinal flat surface of a liquid storage cup and the heat insulation sleeve, and discharging the heat outside the cotton-free electronic cigarette through thermal conductivity of the heat insulation sleeve.
