Cigarette heating device

Abstract

The invention discloses a cigarette heating device, and belongs to the technical field of cigarette smoking sets. A smoke cooling segment of a hollow structure is arranged at an opening end of a cigarette insertion hole, and a refrigeration device is arranged at the outer side of the smoke cooling segment; by designing heat dissipation parts of the refrigeration device to make the heat dissipationspeeds of the heat dissipation parts in the axial direction of the cigarette heating device different, heat dissipation is conducted to different degrees at different positions of the smoke cooling segment; specifically, the heat dissipation speeds of the heat dissipation parts close to a cigarette tobacco segment is greater than those of the heat dissipation parts close to a cigarette filter tipsegment, and therefore the purposes are achieved that high-temperature smoke entering the smoke cooling segment is cooled rapidly, and smoke about to enter the cigarette filter tip segment is cooledslowly; the problem is solved that when a smoker uses the cigarette heating device to smoke, the temperature of smoke entering the mouth cannot be effectively controlled; the high-temperature smoke which just enters the smoke cooling segment is cooled rapidly, and the service life of the refrigeration device is prolonged to a certain degree.

Description

technical field [0001] The invention relates to a cigarette heater and belongs to the technical field of cigarette smoking sets. Background technique [0002] Traditional cigarettes are ignited and smoked. When the tobacco burns, the temperature can reach 800°C. During the combustion of tobacco, nicotine, carbon monoxide, tar, etc. will be produced. Get satisfied. Studies have shown that most of the harmful substances produced by smoking come from the tar produced during the combustion of tobacco. Tar is usually produced above 400°C, while nicotine and tobacco aroma that satisfy smokers are usually produced at around 300°C. In order to minimize the harm to the human body under the premise of satisfying the smoker's smoking purpose, a product called a heat-not-burn cigarette has appeared on the market. [0003] Heat-not-burn cigarettes use cigarette heaters to heat cigarettes to about 300°C without burning them, thereby reducing the production of harmful substances and avoi...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the existing problem that the smoke temperature at the entrance cannot be effectively controlled when smokers use the cigarette heater to smoke cigarettes, the present invention provides a cigarette heater, which includes a smoke cooling section , the flue gas cooling section is arranged at the opening end of the cigarette insertion hole, and is a section of hollow structure, which is used for gradient cooling of the flue gas circulating from the shredded tobacco section of the cigarette to the filter section of the cigarette. device
