Cotton-free electronic cigarette, heat-insulating and heat-dissipating component of vaporizer device, and method for heat insulation and heat dissipation

A heat-insulating and heat-dissipating component of a vaporizer device of a cotton-free electronic cigarette, characterized in that:

• a 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 liquid storage cup has an exterior longitudinal flat surface, a vapor flow passage is formed between the exterior longitudinal flat surface and the heat insulation sleeve;
• and
• the heat insulation sleeve is arranged inside the outer pipe and outside the liquid storage cup, a circumferential protrusion of a supporting frame and a power connecting assembly that are received in the outer pipe;
• the heat insulation sleeve starts from a position of a liquid percolation piece of the vaporizer device and terminates at a position of the power connecting assembly;
• the heat insulation sleeve, the outer pipe, the liquid storage cup, the circumferential protrusion of the supporting frame, the power connecting assembly, and the liquid percolation piece of the vaporizer device have the same central longitudinal axis.
