Cigarette used for heating non-combustion cigarette

Abstract

The invention discloses a cigarette used for a heating non-combustion cigarette. The cigarette sequentially comprises a cigarette core section (1), a support section (2), a cooling section (3) and a filter tip section (4), wherein the support section (2) is provided with an axial cavity (21); the cooling section (3) is a hollow pipe with a pipe wall (31) and a pipe cavity (32), and the inner wallof the pipe wall (31) is a non-woven fabric layer adopting a high polymer material; and the support section (2), the cooling section (3) and the filter tip section (4) are wrapped by forming paper (5)to form a ternary compound tip rod, the cigarette core section (1) is wrapped by cigarette paper (6) to form a tobacco section, and the ternary compound tip rod and the tobacco section are connectedand mounted through tipping paper (7). For the cooling section of the cigarette, while the cooling effect is guaranteed, the interception for smoke is reduced, then the passing amount of the smoke isincreased, meanwhile, the cooling section seldom collapses, and therefore, the support performance of the cooling section for the cigarette is improved.

Description

technical field [0001] The invention relates to the field of heat-not-burn cigarettes, in particular to a cigarette used for heat-not-burn cigarettes. Background technique [0002] Heat-not-burn cigarettes use an external heat source to heat the tobacco sheet, and the tobacco can release smoke and nicotine only by heating and not burning. The harmful chemical components and toxicity of the gas are greatly reduced; at the same time, the sidestream smoke is greatly reduced, reducing the harm of second-hand smoke to non-smokers. [0003] Heat-not-burn cigarettes generally control the heating temperature of tobacco below 400°C, and reach the atomization temperature at 250°C to 350°C. The temperature of high-temperature atomized smoke entering the mouth through the filter section will be higher than that of traditional cigarettes. air temperature. The development of a cigarette structure with suitable smoke temperature and sufficient smoke release is the key to electric heating...

AI Technical Summary

Problems solved by technology

[0004] At present, heat-not-burn cigarettes in the prior art all use multi-stage filter rods to process the smoke generated by the core section. The filter rods include a support section, a cooling section, and a filter section. The purpose of the cooling section is To reduce the temperature of the flue gas produced by the smoke core section, making it easier to enter, the polylactic acid material gathered in the prior art is used as the cooling section, which still has the following problems: 1. When cooling the smoke produced by the smoke core section At the same time, it has a large adsorption of smoke, and also retains part of the smoke, resulting in low smoke throughput; 2. The polylactic acid material is thermoplastic, and it is easy to deform when heated, causing the cooling section to collapse, thus affecting the cooling section's effect on the cigarette. Support performance; 3. Carrying incense in the cooling section needs to be carried out separately after the cigarette cooling section is prepared, the process is complicated and the cost is high
