Description

Technical Field

[0001] The present invention relates to the technical field of smoking articles, and in particular to an electromagnetic smoking set matched with a metal foil heating cigarette. Background Art

[0002] Traditional cigarettes need to be ignited by open flames to produce tobacco smoke. During the high-temperature combustion process, tobacco releases thousands of mixtures that are harmful to the human body. This mixture is composed of volatile substances, semi-volatile substances present in particles and dust, such as carbon monoxide, phenols, aldehydes, nicotine (nicotine), tar, etc. Low-temperature non-combustion baked tobacco can effectively reduce the production of harmful substances.

[0003] Although the e-cigarettes and low-temperature baked cigarettes currently on the market can reduce the production of harmful substances during the smoking process, the user experience still needs further improvement. Specifically, the smoking material is directly heated to release volatile chemical mixtures. The volatiles are in the heating area, the smoke temperature is generally high, and the burning and irritation are strong, which has an adverse effect on the sensory quality of the smoke.
