Abstract

The invention discloses an electric heating smoking device which heats tobacco from the outside, which comprises a mouthpiece section, a tobacco heating section and a power supply section. The tobacco heating section is composed of a columnar heat source, a tobacco filling cavity and a shell. They are respectively connected to the mouthpiece section and the circuit. The tobacco filling cavity is located inside the columnar heat source and passes through the columnar heat source in the axial direction. At least one side of the tobacco filling cavity is connected to the shell, and the shell is connected to the tobacco filling cavity. The parts are provided with ventilation holes. The invention increases the contact area between the heat source and the tobacco product, so that the tobacco product is heated more evenly, has higher heating efficiency and faster smoke generation, and can be smoked within 0.5 minutes after the circuit is energized, and the smoke is rich and fragrant. Stable, low irritation, less miscellaneous gas.

Description

technical field [0001] The invention relates to an electric heating smoking device. Background technique [0002] Since the "Framework Convention on Tobacco Control" came into effect, the global tobacco industry has faced pressure from various parties. The development of new low-harm tobacco products is the focus of research and development by major tobacco companies around the world. At present, new heating tobacco products mainly include carbon heating and electric heating. Philip Morris focuses on electric heating cigarettes, and has developed The relevant electric heating cigarette products have been developed. The maximum heating temperature of this product is about 500°C, which is lower than the 950°C of traditional cigarettes, which significantly reduces the release of harmful components of cigarettes and environmental smoke. At present, electric heating cigarettes are mainly in the form of inner needle insertion and peripheral heating of tobacco products. The inner ...
