Aerosol generating device and temperature control method therefor

A temperature control method for an aerosol generating device, comprising:

• providing a heating element and a housing, the heating element and a housing wall of the housing being at least partially spaced apart, the heating element being powered on to generate infrared light, the housing wall of the housing being configured to allow the infrared light to pass through;
• obtaining a housing wall temperature of the housing wall;
• obtaining a preset temperature;
• obtaining the heating element temperature of the heating element;
• outputting a target control temperature based on the preset temperature and the housing wall temperature;
• processing the heating element temperature and the target control temperature using a preset algorithm;
• and
• adjusting power supplying of the heating element.

A method for controlling a temperature of an aerosol generating device, the method comprising:

• providing the aerosol generating device, the aerosol generating device comprising:
• a heating element configured to generate infrared light;
• a housing having a housing wall configured to allow the infrared light to pass through, the heating element and the housing wall being at least partially spaced apart;
• a first temperature obtaining unit configured to obtain the housing wall temperature of the housing wall;
• a second temperature obtaining unit configured to obtain the heating element temperature of the heating element;
• and
• a control unit;
• outputting, with the control unit, a first target temperature when the housing wall temperature is less than the preset temperature, and outputting a second target temperature when the housing wall temperature is not less than the preset temperature, the first target temperature being greater than the second target temperature,
• processing, with the control unit, the heating element temperature and the target control temperature using a proportion-integration-differentiation (PID) control algorithm;
• and
• adjusting, with the control unit, a power supplying of the heating element,
• wherein the target control temperature comprises the first target temperature and the second target temperature.
