Heat-not-burn cigarette based on semiconductor refrigerating and heating functions

Abstract

The invention relates to a heat-not-burn cigarette based on semiconductor refrigerating and heating functions, which comprises a shell, an atomization module and an electrical module, the atomizationmodule and the electrical module are respectively arranged in the shell, and the atomization module comprises a plurality of semiconductor thermoelectric elements (6) and an atomization unit which arerespectively and electrically connected with the electrical module, the plurality of semiconductor thermoelectric elements (6) surround in the circumferential direction to form a heating cavity (17),the atomization unit is arranged in the heating cavity (17), a thermal insulation material (10) is arranged on the inner wall of the shell, and a secondary air channel (7) is formed between the thermal insulation material (10) and the semiconductor thermoelectric elements (6). And a primary air inlet (3) communicated with the heating cavity (17) and a secondary air inlet (4) communicated with thesecondary air channel (7) are respectively formed in the shell. Compared with the prior art, the cigarette has the advantages that the temperature of the cigarette rod cannot scald hands, the smoke temperature can be reduced, and the smoke effect is good.

Description

technical field [0001] The invention belongs to the technical field of heat-not-burn cigarettes, in particular to a heat-not-burn cigarette based on semiconductor cooling and heating functions. Background technique [0002] Heat-not-burn cigarettes are a new type of tobacco product, and the market share of related products in the global tobacco industry is gradually increasing. Compared with traditional cigarettes, heat-not-burn cigarette products do not burn during the smoking process of users, and the smoke produced does not contain carcinogenic chemicals such as tar and solid particles produced by high-temperature combustion, that is, in aerosol smoke The harmful chemical components in the smoke have been greatly reduced, which has slowed down the damage to the health of smokers, and thus has attracted more and more attention. [0003] At present, related products of heat-not-burn cigarettes have technical defects such as the temperature of the tobacco rod is too high to...

AI Technical Summary

Problems solved by technology

Compared with the present invention, this patent is mainly based on the thermoelectric power generation element using the temperature difference between the inner and outer walls of the smoke rod to generate electricity. The heat insulation effect of the smoke rod is poor, and the temperature of the flue gas cannot be reduced.
