The high-frequency alternating current generates high-frequency alternating magnetic field in the coil. A large number of annular eddy currents are generated inside, and the eddy current thermal effect of small resistance and large current releases a large amount of heat to make the metal material heat up at a high speed, and then heat other substances. Induction cookers and electromagnetic rice cookers made using the principle of electromagnetic induction heating have been widely used in people's daily life. Compared with traditional heating methods, electromagnetic heating technology has the advantages of fast heating speed, high thermal efficiency, easy control of heating temperature, energy saving and environmental protection, and easy heating. Process automation and other features.

The new type of cigarette is characterized in that it only heats tobacco or tobacco extract instead of burning tobacco, releases less harmful components and provides consumers with a certain tobacco characteristic experience. New cigarettes (also called heat-not-burn cigarettes) mainly include electric heating, carbon heating, physical and chemical reaction heating, and other heat source types. Since the 1980s, international tobacco companies have started research and development of new cigarettes. In recent years, the research and development of products has been continuously intensified. my country's tobacco industry started late in the research of new cigarettes and is still in its infancy.

In terms of electric heating cigarettes, "Accord" developed by Philip Morris USA and "Heatbar" developed by Philip Morris International (PMI) are representatives of electric heating tobacco products. Both are composed of special cigarettes and electric heaters. Philip Morris (PM) focuses its research and development on reducing the burning temperature of cigarettes, hoping to make tobacco release flavor through heating instead of burning, so as to win the favor of consumers. The first and second generation Electrically Heated Cigarette Smoking System (EHCSS, Electrically Heated Cigarette Smoking System) such as Accord, Heatbar and other brands have been developed successively. The maximum temperature of tobacco in Accord products is about 500°C, which is lower than the 950°C of traditional cigarettes, which significantly reduces the harmful components of cigarettes and the release of environmental smoke. Patent US6615840 discloses an electric smoking system and its method, including a special cigarette and a heater, the heater includes multiple heating blades and a heating electromagnetic control system, the temperature in the heating area is controlled not to exceed 450°C, and the shredded tobacco is heated to about 200-350°C. Patent US6994096 discloses a heater bracket used in an electric heating smoking system. Effective contact is established between heater blades and cigarettes, and air flows are introduced in multiple directions at positions adjacent to the cigarettes in effective contact with the heating blades.

Patents (US20110155151, US20050172976, US20040129280, US7690385) introduce an improved electrically heated cigarette with an aroma release control system, which contains additives capable of releasing aroma. The electric smoking system includes a special electrically heated cigarette and a reusable lighter, and a control circuit can selectively control one or more heating elements during each puff. In the electric smoking system disclosed in the patent US2007102013, a special cigarette is placed in a heating system, and the tobacco is heated by contact conduction and hot air convection, so that the temperature of the tobacco reaches about 150-220°C, so that the tobacco releases volatile aroma components.
