Electromagnetic induction type heating smoking set for heating non-combustible tobacco products

Abstract

The invention discloses an electromagnetic induction type heating smoking set for heating non-combustible tobacco products. The electromagnetic induction type heating smoking set comprises a heating cup (2), one side of the heating cup (2) is provided with an opening used for containing the tobacco product (4), and a heating element (1) inserted into the tobacco product for heating is arranged in the heating cup (2); a sleeve (6) is included and is coaxially arranged with the heating cup, and the heating cup is located in the sleeve (6); an induction coil (5) is included and arranged on the outer wall of the heating cup; and a power supply (8) is included and is used for providing a high-frequency alternating current for the induction coil so that the induction coil generates an alternating magnetic field of which the direction is continuously changed, a vortex current appears on the wall surface of the heating element in the alternating magnetic field, the heating element is heated by the joule heating effect of the vortex current, and the tobacco product is heated. A wireless energy transfer heating mode is adopted, the heating efficiency is effectively improved, and the heating time is effectively shortened.

Description

technical field [0001] The invention relates to a heat-not-burn tobacco heating device adopting an electromagnetic induction heating method. Background technique [0002] Heat-not-burn tobacco products are much safer than traditional cigarettes. Different from the working principle of e-cigarettes, heat-not-burn tobacco products are characterized by using an external heat source to heat tobacco instead of igniting it, which is the most essential difference between it and traditional tobacco. The smoking temperature of heat-not-burn cigarettes is generally below 300°C, and only distillation and relatively simple pyrolysis reactions occur, which can effectively reduce the production of many potentially harmful substances due to high-temperature combustion, pyrolysis and thermal synthesis. Reduce the harm of tobacco products to the human body. In terms of emissions, heat-not-burn tobacco products are 5% of traditional cigarettes. From the perspective of cytotoxicity, heat-no...

AI Technical Summary

Problems solved by technology

[0003] Traditional carbon-heated and fuel-heated heat-not-burn tobacco appliances have high suction resistance, peculiar smell, exhaust gas, and slow heating speed, which have certain safety hazards and are not conducive to subsequent branding and marketing of products

In addition, the temperature control of heat-not-burn tobacco smoking appliances is generally realized by temperature sensor feedback control. This control method will complicate the circuit board design and is not conducive to the miniaturization of smoking appliances
