Background

The heating cigarette is a novel tobacco product different from the traditional cigarette, and mainly heats tobacco in a low-temperature range without initiating combustion in a controllable mode. Heating cigarettes by evaporation or distillation produces an aerosol consisting primarily of water, glycerin and nicotine, which is considered an acceptable alternative to smoking because it is close in consumption, taste, smell and nicotine intake to traditional cigarettes. Compared with the traditional cigarette, the smoking heating type tobacco products can smoke the tobacco, including cut tobacco, tobacco fragments, tobacco particles, tobacco powder and the like. When a consumer smokes and heats the cigarette, the flow measuring smoke is hardly generated, and the smoke almost entering the environment is little, so that the environmental pollution is greatly reduced. Heated cigarettes are gaining popularity with a segment of tobacco consumers due to their extremely low tar content and environmental friendliness, and are becoming accepted by cigarette consumers in most countries.

In the process of heating cigarette development, the heating temperature is lower than that of the traditional cigarette, and the generated smoke contains higher moisture, so that the cigarette has higher sensing temperature than the smoke of the traditional cigarette; in addition, the cigarette is shorter, so that the burning phenomenon exists in the inlet smoke temperature, and the great difference exists between the smoking experience, the smoking feeling and the like and the traditional cigarette. Therefore, the final smoke temperature of the heated cigarette can be effectively controlled by accurately measuring the temperature of the heated cigarette, and the use experience of consumers can be improved.

The thermocouple is used as a temperature measuring device, is suitable for measuring the accurate temperature of the position to be measured of the heated cigarette, is beneficial to effectively evaluating the internal structure and the temperatures of different parts of the heated cigarette, and can provide technical support for product development.
