Non-combustion-cigarette graphite heating device

Abstract

The invention relates to a non-combustion-cigarette graphite heating device which comprises an outer shell, a thermal insulation sleeve and a heater. A cigarette inlet for allowing a tobacco product to be inserted is formed in 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, the thermal insulation sleeve is arranged between the heater and the outer shell, a graphite heating element is adopted in the heater, a heating cavity for containing the tobacco product is formed in the middle of the graphite heating element, the front end of the heating cavity is communicated with the cigarette inlet, and the rear end of the heating cavity is communicated with the air inlet. The non-combustion-cigarette graphite heating device has the advantages of being high in heat availability, capable of heating at constant temperature, high in temperature control precision, good in stability and long in service life, aroma components in cigarettes can be distilled in a dry mode through the graphite heating mode, the cigarette is not directly combusted, the harm of the cigarette to the human body is reduced, and it is ensured that a consumer can obtain the characteristic feeling of the tobacco.

Description

technical field [0001] The invention relates to the technical field of novel cigarettes, in particular to a graphite heating device for non-combustion cigarettes. Background technique [0002] Traditional cigarettes have been the mainstream product form of tobacco consumption for more than 100 years. With the change of people's lifestyle and consumption concept, the rapid progress of science and technology and the accelerating speed of commodity upgrading, the needs and concerns of tobacco consumers are constantly changing. 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-smokers, and fires caused by smoking are difficult to eradicate. Nicotine and most tobacco aroma components can be transferred into the smoke at 200-500 degrees Celsius. The combustion temperature of conventional cigarettes is above 800 degrees ...

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
