Heating cigarette supporting section, heating cigarette composite filter tip and heating cigarette

Abstract

The invention discloses a heating cigarette supporting section, a heating cigarette composite filter tip and a heating cigarette, the heating cigarette supporting section comprises a sleeve and an isolation column, and the sleeve is provided with a through groove penetrating in the axial direction of the sleeve; the through groove comprises a first cavity, a mounting cavity and a second cavity which are connected in sequence; the isolation column is mounted in the mounting cavity, and a plurality of through holes penetrating in the axial direction of the isolation column are formed in the isolation column; the sum of the radial cross-sectional areas of the through holes is smaller than the radial cross-sectional area of the first cavity, and the sum of the radial cross-sectional areas of the through holes is smaller than the radial cross-sectional area of the second cavity. In the application, in the process that high-temperature smoke enters the second cavity from the first cavity through the through hole, a low-pressure area full of vortexes can be generated near the necking, smoke aerosol collides and condenses to release heat, release energy and generate energy loss, the high-temperature smoke can be cooled, and water vapor can be condensed, so that the smoke can be cooled, and the smoke can be cooled. The temperature of smog smoked by a user can be ensured to be appropriate, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of cigarettes, and in particular, to a heated cigarette support section, a heated cigarette composite filter tip, and a heated cigarette. Background technique [0002] With the development of society and the improvement of people's health awareness, traditional cigarettes are subject to extensive restrictions due to the burning and cracking of a large number of harmful substances, which are unfavorable to human health, and the number of people who smoke traditional cigarettes is also decreasing. As a new type of tobacco product that is closest to traditional cigarettes, heated cigarettes have become the main research direction of the tobacco industry because the tobacco materials are not burned, which can reduce the harmful chemical components and biological toxicity of smoke. [0003] At present, heated cigarettes usually have a four-section structure, including a tobacco section, a hollow section...

AI Technical Summary

Problems solved by technology

There are still disadvantages such as high flue gas temperature, high moisture content, collapse of the hollow section of the acetate fiber near the tobacco section, and generation of peculiar smell during smoking.
