AI Technical Summary
The metal heating wire in traditional electronic cigarettes will cause the heated air to have a metallic odor when heating the air, affecting the taste of the smoke.
An air heating device is designed to use the gas conducting tank of the thermally conductive body to heat the gas. The gas only comes into contact with the thermally conductive body to avoid contact with the metal heating element, so as not to produce harmful substances or odors. The thermally conductive main materials are non-metallic materials such as ceramics, silicon dioxide, alumina, silicon nitride, zirconium oxide, silicon carbide, etc., and the gas conduction groove extends along the outer wall to achieve gas heating.
It effectively avoids odor in the heating air, and due to the poor oil absorption of the thermal conductor, it will not combine with e-liquid to produce odor, which enhances the taste of the electronic cigarette.
