Problems solved by technology

[0004] Heat-not-burn cigarettes have a faster temperature rise in the heating stage, and generally heat up to the working temperature within 5 seconds. If the thermocouple temperature control method is used, the disadvantage of temperature control hysteresis makes it prone to burnt smell when smoking
Similarly, if the resistance temperature coefficient temperature control method is used, the disadvantage of low temperature control accuracy will reduce the overall pumping experience

Abstract

The invention belongs to the technical field of heating, and in particular relates to a temperature control system and a control method of an aerosol generating device. The temperature control system includes: a heating element, a characteristic temperature control element of the temperature coefficient of resistance, and a thermocouple temperature control element; the temperature control element with the characteristic temperature coefficient of resistance and the thermocouple temperature control element can independently measure the temperature of the heating element. The present invention adopts the resistance temperature coefficient temperature control method in the first stage including the preheating stage, because the heating element heats up in this stage, and the heating power needs to be adjusted at any time according to the temperature of the heating element, and the resistance temperature coefficient temperature control method responds in time and can be controlled in time Temperature changes, there will be no hysteresis caused by thermocouple temperature control; thermocouple temperature control is used in the second stage including the temperature constant, this stage can accurately control the temperature value, and can maintain the consistency of the atomization temperature of the tobacco substance. The overall pumping experience is consistent.

Description

technical field [0001] The invention belongs to the technical field of heating, and in particular relates to a temperature control system and a control method of an aerosol generating device. Background technique [0002] Heat-not-burn cigarette appliances are usually heated by electric heating, and the temperature control methods usually include two forms of resistance temperature coefficient control and thermocouple temperature control. The temperature control method of the temperature coefficient of resistance has the advantage of fast response speed, but because the temperature coefficient of resistance represents the overall temperature distribution of the heating sheet, its temperature accuracy is low. Thermocouple temperature control has the advantage of high temperature accuracy, but because it takes a certain amount of time for the heat to conduct from the heating element to the temperature control thermocouple, there is a certain hysteresis in the thermocouple temp...
