Claim:
1. An adjusting circuit comprising a voltage supplying module, a temperature sensing module and an adjustment outputting module, wherein, the voltage supplying module is connected with the temperature sensing module and the adjustment outputting module, and is configured to provide input voltages to the temperature sensing module and the adjustment outputting module; the temperature sensing module is connected with the adjustment outputting module, and is configured to convert a temperature sensed into an electric signal and transmit the same to the adjustment outputting module; and the adjustment outputting module is configured to adjust an output voltage (V wherein the temperature sensing module comprises a first thermistor unit and a second thermistor unit connected in series, wherein at least one of the first thermistor unit and the second thermistor unit comprises a plurality of thermistors connected in parallel so that the temperature sensing module has a hybrid connection of thermistors; wherein the adjustment outputting module comprises a first comparator, a second comparator and a digital-analog convertor; two inputting terminals of the first comparator are connected with two terminals of the first thermistor unit respectively, and an outputting terminal of the first comparator is connected with a first inputting terminal of the digital-analog convertor; two inputting terminals of the second comparator are connected with two terminals of the second thermistor unit respectively, and an outputting terminal of the second comparator is connected with a second inputting terminal of the digital-analog convertor; a threshold value of the first comparator and a threshold value of the second comparator are determined by the temperature sensing module having the hybrid connection of thermistors as well as the input voltages; wherein the temperature sensing module further comprises a third thermistor unit connected with the first thermistor unit and the second thermistor unit in series, and third thermistor unit comprises at least one thermistor, the adjustment outputting module further comprises a third comparator; the digital-analog convertor further comprises a third inputting terminal; two inputting terminals of the third comparator are connected with two terminals of the third thermistor unit respectively, and an outputting terminal of the third comparator is connected with the third inputting terminal of the digital-analog convertor.
