Low temperature tobacco smoking set heated by hot air

Abstract

A low temperature tobacco smoking set heated by hot air comprises a base (1), an insulating seat (2), a tubular heating element (4), a strip top plate and a shell (5), wherein the base (1) is provided with a first outer ring bearing platform (12) and a first upper part center groove (11); the insulating seat (2) is mounted in a first round center groove; a second upper part round center groove (21) is arranged at the upper part of the insulating seat (2); the tubular heating element (4) is mounted in the second upper part round center groove (21); the strip top plate is located on the first outer ring bearing platform (12); a round bearing platform (53) is formed in the center of the top of the shell (5); a suction nozzle (6) provided with a gas guide channel (62) in the center is mounted on the round bearing platform in an insertion manner; an insertion hole, into which a cylindrical tobacco material (7) can be inserted, is formed in the center of the bottom of the suction nozzle; and a positive electrode (41) and a negative electrode (42) of the heating element respectively penetrate through the insulating seat and are connected with a power supply device. The smoking set has the advantages that the heating uniformity of the tobacco material can be improved, aroma components are promoted to be uniformly and fully released, the suction experience feeling is improved, and charring of the tobacco material is avoided, so as to reduce the generation of harmful substances.

Description

technical field [0001] The invention relates to the technical field of smoking set structure for smoking non-burning low-temperature tobacco. Background technique [0002] Relevant studies have shown that the burning temperature of conventional cigarettes is above 800 degrees Celsius, and more than 5,000 chemical substances are produced during the burning process of cigarettes, including more than 80 carcinogenic chemicals. The smoke produced is quite harmful to non-smoking people. With the launch of a series of low-temperature non-burning heaters, a new tobacco heating method that can effectively reduce the production of harmful substances has emerged. The harmful substances produced by this low-temperature heating method are much less than those produced by burning cigarettes. While meeting the needs of consumers, it can reduce the harm to the body. [0003] At present, the mainstream low-temperature heating and non-burning heating appliances directly heat the contacted t...

Problems solved by technology

[0003] At present, the mainstream low-temperature heating and non-burning heating appliances directly heat the contacted tobacco product materials through electric heating elements. The heating elements are in the shape of blades, rods, cups, etc. During the heating process, the part close to the heat source is prone to scorching due to excessive heating, while the tobacco product material far away from the heat source is insufficiently heated, resulting in insufficient release of aroma and active ingredients

This uneven heating heating structure, on the one hand, causes the tobacco material to be unable to be fully utilized, resulting in insufficient aroma and low smoke volume, which reduces the user's puffing experience; Excessive heating may lead to more harmful substances in the flue gas
