Background
Heated cigarettes are a new type of tobacco product that uses a means of heating without burning to produce an inhalable aerosol containing nicotine. The main stream products of the heating cigarettes in the current market are matched with electric heating devices. The heating mode and the highest heating temperature are different according to the diameter of the cigarette. For heated cigarettes with the diameter of less than 7mm, a peripheral heating mode is generally adopted, and the highest heating temperature is generally lower than 300 ℃; for heated cigarettes with a diameter of more than 7mm, a central heating mode is generally adopted, and the highest heating temperature is generally higher than 300 ℃.
The tobacco containing the aerosol in the heated cigarette produces a superheated aerosol material after heating, and the superheated aerosol material cools as it flows or mixes with air, wherein the compounds condense to form an inhalable aerosol.
