Description

low temperature smoking device

technical field

The utility model relates to a low-temperature smoking set.

Background technique

At present, electronic cigarettes on the market mainly include two types, such as electronic cigarettes that form smokeable smoke by evaporating e-liquid, and low-temperature smokes that form smokeable smoke by heating/distilling tobacco materials at low temperatures (150-300 degrees), which are different from traditional cigarettes. Compared with combustion-type cigarettes, electronic cigarettes and low-temperature cigarettes have a lower working temperature, and the harmful components in the smoke produced by the e-liquid or low-temperature cigarettes used are far less than those of traditional combustion-type cigarettes. Therefore, using electronic cigarettes or Low-temperature smoke can greatly avoid the adverse effects of cigarettes on the human body.

Whether it is an electronic cigarette or a low-temperature cigarette, they all use the method of heating the smoke oil or the low-temperature cigarette with the smoking device, so that the smoke-generating medium produces an aerosol for the user to smoke. Due to a series of relatively complex structures, the smoking set itself often has a certain volume. In order to facilitate the user to carry and improve the convenience of use, the structure of the smoking set tends to become smaller and smaller. However, it is difficult to increase the working power of the battery, heating element and smoking set. When the range changes, the smaller the volume of the smoke body, the more difficult it is to solve the heat dissipation problem. Usually, the surface of the smoking set will inevitably have a high temperature when it is used. If it is not used properly, it will seriously even burn the user.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art and provide a sliding door that can be opened automatically by switching on and off, and the door can be closed to isolate external dust and misplaced entry into the smoking set, which has good heat insulation effect, prevents the external temperature of the smoking set from being too high, and replaces the battery at the same time. Convenient low-temperature smoking set.
