Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heated cigarettes, and particularly relates to a heated cigarette based on homologous products. BACKGROUND

[0002] As a new type of tobacco product, heated tobacco products (HTP for short) have rapidly become an important innovation direction of the global tobacco industry in recent years, and their sales in overseas markets have maintained a high growth momentum for several consecutive years. Common heated tobacco products are similar in core structure to traditional cigarettes and both have two key components, namely a tobacco segment and a filter segment. The tobacco segment is usually made of cut tobacco or reconstituted tobacco and releases aerosol containing nicotine and aroma components when heated. The filter segment is usually made of multiple materials and serves to extract smoke, reduce aerosol temperature, and provide support, etc. Heated tobacco products need to be heated by a matching smoking set to generate aerosol during smoking. The smoking set heats the tobacco segment through electromagnetic, infrared, microwave, etc. According to the position of the heat source and the tobacco segment, heated tobacco products can be roughly divided into internal core products with the heat source inside the tobacco segment and circumferential products with the heat source outside the tobacco segment.

[0003] Heated tobacco products need to be continuously heated by a smoking set during smoking, which causes some materials to be continuously heated beyond expectations, such as paper materials wrapping the tobacco segment or filter segment materials connected to the tobacco segment, which makes the above-mentioned non-tobacco materials produce off-flavors when heated, thereby affecting the aroma quality and sensory experience of the cigarette.

[0004] Therefore, how to design a heated cigarette based on homologous products to reduce the generation of off-flavors and improve the aroma quality and sensory experience of the cigarette has become a technical problem that technicians in the field urgently need to solve. SUMMARY
