The present invention relates to the technical field of cigarette processing and manufacturing, and in particular to a heated non-combustion cigarette filter and a heated non-combustion cigarette.

As governments in various countries continue to strengthen their tobacco control efforts and people pay more and more attention to health, the space for the tobacco industry to rely on traditional paper cigarettes for profit growth is also shrinking. Therefore, it is actively developing a new type of tobacco product that reduces the release of harmful components of tobacco. A necessary choice.

Heating non-burning cigarettes uses special heat sources to heat the shredded tobacco (about 300 ° C). The shredded tobacco only heats and does not burn. The shredded tobacco temperature is far lower than that of traditional cigarettes. The harmful chemical components and biological toxicity of the smoke are greatly reduced, which can reduce the tobacco high-temperature combustion cracking. At the same time, unlike the shame of traditional cigarettes, the shredded tobacco is in a non-heated state during the smoking interval, so the sidestream smoke and environmental smoke are also greatly reduced.

In view of the unique advantages of heating non-burning cigarettes, Philip Morris Manufacturing, British American Tobacco, Reynolds Tobacco, etc. Systematic research has been conducted on the related technologies of heating non-combustion cigarettes, especially the layout of intellectual property rights for heating non-combustion cigarettes. In recent years, domestic tobacco companies have carried out a lot of research on heating non-burning cigarettes. For example, CN103584288 A, CN103859597 A, CN203735475 U and other patents focus more on the design of heating devices and the coordination of cigarettes and heating devices. Less research.
