Closed heating type cigarette with smoke channel

Abstract

The invention belongs to the field of heat-not-burn cigarettes, and particularly relates to a closed heating type cigarette with a smoke channel. The cigarette comprises a plug (5), a tobacco section(1), a low-suction-resistance section (2) and a functional filter tip section (3) which coaxially abut against one another in sequence from upstream to downstream, and the cigarette is wrapped with anouter wrapping piece (4). The low-suction-resistance section (2) is a pipe body provided with an axial center cavity (2-1) and at least one circumferential side wall through hole (2-2), and an axialfirst smoke channel (1-1) is formed in the axis of the tobacco section (1). According to the cigarette, a plurality of axial channels are designed in the tobacco section for the first time, and diffusion of smoke in the tobacco section is facilitated.

Description

technical field [0001] The invention belongs to the field of heat-not-burn cigarettes, in particular to a closed heating cigarette with a smoke channel. Background technique [0002] Traditional tobacco has a history of hundreds of years and has been integrated into the lives of most smokers. In recent years, with the improvement of people's living standards, people have paid more and more attention to issues such as smoking and health, and the hazards of second-hand smoke, and the harmfulness of traditional tobacco products has become increasingly prominent. At the same time, with the implementation of the WHO Framework Convention on Tobacco Control, especially the gradual expansion of the scope of smoking bans in public places around the world, the development environment of tobacco products has undergone major and profound changes, and the structure of tobacco products is moving towards diversification. And the development direction of smoke-free to accelerate the adjust...

AI Technical Summary

Problems solved by technology

[0003] At present, the vast majority of heat-not-burn cigarettes use air as the carrier of smoke. In order to ensure that the tobacco does not burn, the heating temperature applied is usually lower, generally not exceeding 300°C. Compared with traditional cigarettes, the new heat-not-burn The tobacco aroma components of cigarettes are difficult to fully release, and the smoke volume is insufficient, so this kind of cigarettes are difficult to be accepted by traditional smokers

In addition, in order to ensure air circulation, the tobacco end of most heat-not-burn cigarettes is an open structure, that is, the shredded tobacco or reconstituted tobacco sheet is directly exposed outside, or is connected to the outside atmosphere through a certain airflow channel. During the process of ejecting pods, tobacco residues will fall, which is easy to pollute the smoking equipment. Therefore, after using this type of tobacco for a period of time, it takes time to clean the smoking equipment.

The above-mentioned problems can be effectively solved by adopting a closed heating cigarette structure, but it is difficult to diffuse the smoke generated by the tobacco section in the closed cigarette structure
