Quaternary composite electric heating incombustible cigarette

Abstract

The invention discloses quaternary composite electric heating incombustible cigarette, and belongs to the technical field of heating incombustible cigarette. The quaternary composite electric heating incombustible cigarette consists of a heating segment, a guide segment, a cooling segment and a filtering segment, wherein the heating segment is a layered smoking stick made of regenerated tobacco, bamboo fiber paper or coating molding paper; the guide segment comprises a first hollow filter stick and is connected with the heating segment; the cooling segment comprises a second hollow filter stick and is connected with the guide segment; the airflow retention area of the second hollow filter stick is larger than that of the first hollow filter stick; the filtering segment is connected with the cooling segment. The quaternary composite electric heating incombustible cigarette is applicable to heating devices of different heating modes of central heating, peripheral heating and the like, and is also applicable to heating incombustible cigarette devices of different device specifications; on the premise that the smoke quantity of cigarette is ensured, the temperature of fume entering mouths is lowered, and certain harmful substances are adsorbed; mental and physiological needs of customers can be relatively well met.

Description

technical field [0001] The invention relates to an electric heating non-burning cigarette, in particular to a special electric heating non-burning cigarette with a quaternary composite structure, which belongs to the technical field of heating non-burning cigarettes. Background technique [0002] Heat-not-burn cigarettes provide consumers with nicotine and tobacco flavor substances by heating tobacco instead of burning it. Compared with traditional cigarettes, heat-not-burn cigarettes reduce the high-temperature combustion and cracking process, and the harmful components in the smoke are greatly reduced. [0003] Foreign tobacco companies have carried out decades of research in the field of heat-not-burn cigarettes, forming three main technical directions: electric heating, fuel heating and chemical heating. Among them, the more influential ones are Accord, Heatbar, iQOS and other products successively developed by Philip Morris in the field of electric heating new cigarett...

AI Technical Summary

Problems solved by technology

[0004] The smoking material for non-burning cigarettes in the prior art includes crushing tobacco raw materials into powder, expanding and granulating through microwaves, and then fully mixing with spice plant granules, tobacco essence, starch adhesive, propylene glycol and tobacco starch humectant Finally, the semi-finished product of the smoking material is obtained, which is finally obtained by pressing and forming through a mold. However, it cannot control the amount of smoke, and cannot reduce the temperature of the smoke of the cigarette, and the smoking effect is not good.

There are also heat-not-burn cigarettes made of reconstituted tobacco leaves, including a chimney, cigarette paper wrapped outside the chimney, and a composite filter rod connected to one end of the chimney. Cigarette smoke is easy to generate and release quickly and in large quantities. However, the composite filter of this cigarette The rod only includes a hollow section and a solid section. During the smoking process of the cigarette, it is difficult to effectively reduce the smoke temperature of the cigarette while ensuring a certain amount of smoke
