Multi-stage electromagnetic induction heating system used for low temperature tobacco

Abstract

The invention relates to a multi-stage electromagnetic induction heating system used for a low temperature tobacco. The inner wall of the multi-stage electromagnetic induction heating system used forthe low temperature tobacco is wrapped around the low temperature tobacco, external shielding sleeves the external portion of the inner wall, several electromagnetic induction heat sources are uniformly distributed between the inner wall and the external shielding, and annular shielding is arranged between the adjacent electromagnetic induction heat sources. Each electromagnetic induction heat source is formed by an excitation coil and an electromagnetic pole sheet, and the electromagnetic pole sheet sleeves the inner wall. The excitation coil is winded around the electromagnetic pole sheet, and two ends are connected to an electromagnetic induction power supply. The electromagnetic induction power supply is connected to an external circuit control system. Electromagnetic intensity is adjusted through the input voltage of the electromagnetic induction power supply. By using the multi-stage electromagnetic induction heating system, a consumer can open the electromagnetic induction heatsources according to the number of suction, which greatly increases the consumption experience of the consumer, the temperature distribution of electromagnetic induction heating on the low temperaturetobacco can be effectively controlled, and a uniform heating effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of novel tobacco products, and in particular relates to a multi-stage electromagnetic induction heating system for low-temperature tobacco. Background technique [0002] Combustion of traditional cigarettes generally needs to reach about 900°C, and nearly 6,000 chemical substances will be released during the combustion and cracking process, of which only about 1 / 3 come from the tobacco itself, and 2 / 3 of the chemical substances are new after combustion. Produced, including some harmful substances such as polycyclic aromatic hydrocarbons, carbon monoxide, nitrogen oxides, and olefins. These harmful components will endanger the health of smokers after being absorbed by the human body through the smoke, and will also be released into the environment to cause the problem of second-hand smoke. Studies have shown that nicotine and most tobacco flavor components can be transferred to smoke at lower temperatures (3...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the deficiencies in the above-mentioned prior art, and proposes a multi-stage electromagnetic induction heating system for low-temperature tobacco, which not only completely solves the phenomenon of uneven heating of low-temperature tobacco by electromagnetic induction in terms of principle and structure, but also consumers can according to The demand for the number of self-puffs, independent switching of a single electromagnetic induction heat source, greatly increases the consumption experience of consumers, and at the same time, the supporting low-temperature tobacco has a simple structure, lowers the requirements for the appearance of low-temperature tobacco, and reduces the preparation of electromagnetic induction low-temperature tobacco difficulty
