Heating cigarette smoking set with variable airway pressure and using method thereof

Abstract

The invention belongs to the technical field of heating cigarette smoking sets, and particularly relates to a heating cigarette smoking set with variable airway pressure and a using method thereof. The smoking set comprises a suction nozzle (1), a heating cavity (3), a first one-way control valve (5), a piston (6) and a main airflow channel (9). The suction nozzle (1) is arranged above the heating cavity (3) and is in airflow communication with the main airflow channel (9); and the main airflow channel (9) is provided with a channel section variable section (9-1), and a movable piston (6) is arranged on one side of the channel section variable section (9-1). According to the invention, the section of the specific position of the smoke channel of the smoking set is changed, the gas flow rate is changed, the Venturi effect is generated, the air pressure change is controlled, and the one-way control valve is matched for the first time, so that the tobacco section in the heating cavity is sealed and smoke is extracted.

Description

technical field [0001] The invention belongs to the technical field of heated cigarette smoking utensils, in particular to a heating cigarette smoking utensil with variable airway pressure and a use method thereof. Background technique [0002] Traditional cigarettes release nicotine and aroma components in tobacco by burning them to meet the needs of consumers. Heated cigarettes use an external heat source to heat tobacco products to the atomization temperature to achieve the effect of producing smoke. And the heating temperature is lower than the combustion temperature of tobacco, which can significantly reduce a large amount of harmful substances produced by cigarette combustion, and reduce the harm of second-hand smoke to non-smokers. Because the heating temperature of heated cigarettes is lower than the combustion temperature, compared with traditional cigarettes, the tobacco aroma components of heated cigarettes are difficult to fully release, and the amount of smoke ...

AI Technical Summary

Problems solved by technology

However, sealing the bottom of the cigarette during cigarette preparation will greatly change the existing cigarette production process, and the equipment cost is too high

[0003] At the same time, the existing sealing method only seals the bottom of the cigarette. When the cigarette is heated for a long time, part of the smoke will diffuse into the air with the heating time, affecting the taste of smoking.
