Abstract

The invention relates to a heat-not-burn cigarette based on semiconductor refrigeration and heating functions, which includes a housing, an atomization module and an electrical module respectively arranged in the housing, and the atomization module includes a plurality of semiconductors electrically connected to the electrical modules The thermoelectric element (6) and the atomizing unit, a plurality of semiconductor thermoelectric elements (6) surround the heating cavity (17) in the circumferential direction, the atomizing unit is arranged in the heating cavity (17), and the inner wall of the housing A heat insulating material (10) is provided, and a secondary air channel (7) is formed between the heat insulating material (10) and the semiconductor thermoelectric element (6), and the housing is respectively provided with a heating cavity (17) The primary air inlet (3) and the secondary air inlet (4) connected with the secondary air channel (7). Compared with the prior art, the invention has the advantages that the temperature of the tobacco rod is not hot, the temperature of the flue gas can be reduced, and the effect of the smoke 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...
