Composite filter tip for heating type non-combustion cigarette

Abstract

The invention relates to a composite filter tip for a heating type non-combustion cigarette. The composite filter tip comprises a solid filter (1), a first hollow filter or first cavity (2), a second hollow filter (3) and a third hollow filter or third cavity (4) which are connected in sequence, wherein a fourth cavity (7) is formed in the hollow portion of the first hollow filter or first cavity (2), a sixth cavity (5) is formed in the hollow portion of the third hollow filter or third cavity (4), the fourth cavity (7) and the sixth cavity (5) are in airflow communication through a fifth cavity (6) located in the hollow portion of the second hollow filter (3), and the diameter of the fifth cavity (6) is smaller than that of the fourth cavity (7) and that of the sixth cavity (5). The composite filter tip has a smoke mixing function, a smoke response time shortening function and other functions and has the advantages of being capable of increasing the smoke amount of the heating type non-combustion cigarette, reducing smoke temperature, improving the smoking sensory quality of the heating type non-combustion cigarette and the like.

Description

technical field [0001] The invention belongs to the technical field of heat-not-burn cigarette mouthpieces, and in particular relates to a novel composite mouthpiece for heat-not-burn cigarettes. Background technique [0002] For heat-not-burn cigarettes, the heating temperature is generally less than 500°C. Studies have shown that the release of harmful components in tobacco smoke is closely related to the heating and combustion temperature, and reducing the heating or combustion temperature can significantly reduce the release of harmful components in smoke. While satisfying consumers' tobacco characteristics, reducing the release of harmful components in smoke and reducing the harm to consumers is the starting point for the design and development of heat-not-burn cigarettes with the characteristics of "heating tobacco instead of burning tobacco". Based on this, compared with other types of new tobacco products such as smokeless tobacco and electronic cigarettes, heat-not...

AI Technical Summary

Problems solved by technology

Physical and chemical reaction heating tobacco products are characterized in that the heat of heating tobacco comes from physical and chemical reactions. However, this type of product has poor control over heat, and the process is relatively complicated, so it has not yet been commercialized.

[0006] However, so far, the market tests of the first two commercialized electric heating non-burning cigarette products (Accord, HeatBar) launched by Philip Morris have not been successful, which further shows that electric heating non-burning cigarette products are still in the early stages of growth and are still in the early stages of development. There are many problems, especially the core problem is that the smoking experience of electric heating non-burning cigarettes is poor, which limits its market promotion to a certain extent, which is specifically reflected in: high smoke temperature, poor smoke uniformity, response Long time, relatively insufficient amount of smoke, etc.
