[0064] As Figure 5 shown is one implementation mode of the temperature acquisition circuit, the resistance value of the second thermistor Rt1 changes with the change of temperature. In this case, the second thermistor Rt1 is also a negative temperature coefficient thermistor, and the second resistor R2 is a fixed resistor, which is used to constitute part of the voltage dividing circuit with the second thermistor Rt1, the resistance value of the second resistor R2 determines the proportion of the voltage dividing circuit, and an appropriate resistance value is usually selected to produce measurable voltage changes at different temperatures, and the second capacitor C2 is used to filter high-frequency noise in the voltage signal, thereby improving the stability of the output voltage; specifically, when the temperature changes, the resistance value of the second thermistor Rt1 also changes, resulting in a corresponding change in the voltage at the voltage dividing point, and then converting the temperature information into a voltage signal.
