Compared with traditional cigarettes, heat-not-burn cigarettes only heat the tobacco materials or tobacco extracts instead of burning. The heating temperature of heat-not-burn cigarettes is generally about 300 °C, and the harmful substances released by the smoke of its tobacco products are greatly reduced. In order to achieve accurate temperature control and energy consumption optimization management, the temperature distribution of the whole cigarette set under different operating conditions was analyzed, and the change law of the temperature field of the electric heating non-combustion cigarette heater was obtained. Through theoretical simulation and actual experiment, the research results of heating comparison and analysis of the temperature field distribution law of the micro heaters of different structure sizes and materials during the no-load natural heat transfer process, can be optimized and designed for subsequent electric heating non-combustion cigarette heaters. Theoretical and experimental guidance and support are provided for in-depth analysis of heat transfer mechanisms, precise temperature control, and optimized management of energy consumption for subsequent products, and further promote the development and application of domestic heat-not-burn cigarette products.
