TEMPERATURE CONTROL CIRCUIT AND METHOD FOR CIRCUIT BOARD OF ELECTRIC HAIR DRYER

WIPO Patent Application WO/2021/129162

A1

The present application relates to a temperature control circuit and method for a circuit board of an electric hair dryer. The temperature control circuit comprises: a control module, configured to control the turning on or turning off of an electric hair dryer; and a temperature measurement module, connected to the control module. The temperature control method comprises: presetting a safe voltage threshold in the control module; the temperature measurement module outputting a real-time voltage value and sending the real-time voltage value to the control module; the control module receiving the real-time voltage value and comparing the real-time voltage value with the safe voltage threshold, and if the real-time voltage value is not within the safe voltage threshold, the control module controlling an electric hair dryer to be turned off. The present invention can measure the temperature of a circuit board in real time and stop the operation of an electric hair dryer according to the measured temperature so as to protect same.
