Cigarette support for heating non-burning cigarettes

Abstract

The invention discloses a cigarette support for heating non-burning cigarettes. The cigarette support comprises a cigarette core section (1), a cooling section (2) and a filter tip section (3) in sequence; the cooling section (2) is a hollow pipe with a pipe wall (21) and a pipe cavity (22), and the inner wall of the pipe wall (21) is a polymer material non-woven fabric layer (23); the cooling section (2) and the filter tip section (3) are wrapped in forming paper (4) to form a binary composite filter tip rod; the tobacco core section (1) is wrapped in cigarette paper (5) to form a tobacco section, and the binary composite filter tip rod and the tobacco section are spliced with each other through splicing paper (6). According to the cigarette support, the cooling section of the cigarette support ensures the cooling effect; at the same time, the interception of smoke is reduced, and the passing flow of the smoke is increased. Meanwhile, the cigarette filter tip rod is the binary composite filter tip rod, so that the cigarette filter tip rod is simpler to produce and low in cost.

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. The cigarette filter rod has a complex structure and high production cost; 4. The incense loading 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
