Sealed fuming device with air exhaust function and using method of the sealed fuming device

Abstract

The invention belongs to the technical field of heating cigarette smoking sets, and particularly relates to a sealed fuming device with an air exhaust function and a using method of the sealed fuming device. The fuming device comprises a heating cavity (2), the upper end of the heating cavity (2) is provided with a cigarette sealing assembly, a heating cavity sensing device (2a) or a barometer is arranged in the heating cavity (2), and the heating cavity sensing device (2a) can sense whether air exists in the heating cavity (2) or not or sense the air pressure in the heating cavity (2) and output a signal; and an air extractor is included and is in airflow communication with the heating cavity (2) through a connecting port (4) and exhausts the air through an exhaust port (8), and the exhaust port (8) can be closed automatically or manually. The heating cavity with the air exhaust bottom sealed is designed for the first time, the heating cavity is provided with the cigarette sealing assembly and the air extractor for exhausting air in the heating cavity, air in the sealed heating cavity can be exhausted after the cigarette is inserted, and the cigarette can be heated under the oxygen-free condition. Even if the heating temperature is increased, the combustion phenomenon does not occur, and harmful substances generated by aerobic combustion can be reduced.

Description

technical field [0001] The invention belongs to the technical field of heating cigarette smoking sets, and in particular relates to a sealed smoking device with an air extraction function and a use method thereof. Background technique [0002] Heated cigarette products are accepted and liked by more and more consumers due to their low hazard and technological elements contained in such products. The principle of heating cigarettes is to use the form of baking to make tobacco substances volatilize unique chemical substances such as nicotine in a low-temperature environment, so as to avoid harmful substances from high-temperature combustion. However, in the smoking set, there is still unavoidable oxygen, so that some tobacco substances are oxidized and burned, and certain harmful substances such as tar are volatilized. Therefore, if the cigarette heating chamber can be made into a sealed anaerobic environment, the aerobic combustion of the tobacco substance can be avoided, an...
