Description

Aerosol generates module and heats incombustible cigarette utensil

Technical Field

The utility model relates to an electron cigarette technical field particularly, relates to an aerosol produces module and heating smoking set that does not burn.

Background

The smoke generated by burning the cigarette contains harmful substances such as tar, and the harmful substances can cause great harm to the human body after being inhaled for a long time. In order to overcome the harmful substances generated by the burning of the cigarettes, cigarette substitutes such as a heating non-burning device and the like are provided. The tobacco product is placed in a heat non-combustion device, and nicotine and other compounds in the tobacco product are released under the condition of heat non-combustion to form smoke for smoking.
