Description

[0002] In recent years, as countries have strengthened their tobacco control efforts, scientific researchers have devoted themselves to the research and development of low-harm tobacco products. Existing new tobacco products are based on the three combustion elements of combustibles, ignition points, and combustion aids to construct several mainstream new tobacco products. Electronic cigarette products are based on removing combustibles, replacing tobacco raw materials with electronic cigarette oils configured with glycerin, nicotine, etc., in order to achieve the purpose of reducing the harm of tobacco products. Unlike traditional cigarettes, heated cigarette products reduce the heating temperature, usually below 500°C, to achieve low-temperature heating rather than combustion, thereby greatly reducing the types and contents of harmful components in the smoke. Existing studies have shown that the types and contents of the escaped gas components of tobacco raw materials in atmospheres with different oxygen contents are also different, which provides a new idea for the construction of new tobacco products.
