Resistance wire heating device for non-burning cigarettes

Abstract

The invention relates to a resistance wire heating device for non-burning cigarettes. The device comprises an outer shell, an insulation jacket and a heater, a cigarette inlet allowing tobacco products to be inserted in is formed at the front end of the outer shell, the rear end of the outer shell is connected with an air inlet, the heater is arranged in the outer shell, and the insulation jacket is arranged between the heater and the outer shell. A resistance wire heating element is adopted as the heater and comprises a resistance wire and a ceramic heat-conducting sleeve, the resistance wire is arranged on the outer surface of the ceramic heat-conducting sleeve, a heating chamber for accommodating the tobacco products is arranged in the middle of the ceramic heat-conducting sleeve, the front end of the heating chamber is communicated with the cigarette inlet, and the rear end of the same is communicated with the air inlet. The resistance wire heating device has the advantages of high heat efficiency, constant-temperature heating, high temperature control precision, good stability and long service life.

Description

technical field [0001] The invention relates to the technical field of new cigarettes, in particular to a resistance wire heating device for non-combustible smoke. Background technique [0002] As the mainstream product form of tobacco consumption, traditional cigarettes have a history of more than 100 years. With the change of people's lifestyle and consumption concept, the rapid progress of science and technology and the continuous acceleration of commodity upgrading, the needs and concerns of tobacco consumers are constantly changing. At the same time, affected by factors such as tobacco control and public opinion, traditional cigarettes The development of cigarettes is restricted, and the emergence of new cigarettes has become inevitable. [0003] Studies have shown that cigarette smoke produced by burning cigarettes is extremely harmful to non-smoking people, and fires caused by smoking are difficult to eliminate. Nicotine and most tobacco aroma components can be tran...

AI Technical Summary

Problems solved by technology

Compared with conventional cigarettes, the amount of smoke released is uncontrollable, and the sensory differences between different puff numbers are relatively large, and the sensory characteristics tend to weaken in the later period of smoking

In addition, heating the unheated part of the cigarette too early will cause part of the smoke or cause the part of the cigarette to be thermally degraded by heat, which will change its quality; reheating the previously heated part will cause unpleasant odor or harmful components
