Beschreibung
Zusammenfassung:	The utility model discloses a fan control circuit, and in particular relates to a fan temperature-control speed-regulation circuit which comprises a voltage stabilizing circuit consisting of a current-limiting resistor R4, a capacitor C3 and a voltage stabilizing diode VS, a multivibrator consisting of a resistor R1, a resistor R2, a resistor R3, a capacitor C1, a capacitor C2 and a thermistor RT, and a control execution circuit consisting of a resistor R5, a thyristor VT and a fan motor M. The fan control circuit has the advantages that due to the voltage stabilizing circuit consisting of the current-limiting resistor R4, the capacitor C3 and the voltage stabilizing diode VS, the multivibrator consisting of the resistor R1, theresistor R2, the resistor R3, the capacitor C1, the capacitor C2 and the thermistor RT, and the control execution circuit consisting of the resistor R5, the thyristor VT and the fan motor M, the rotation speed of a fan can be automatically regulated according to indoor temperature so a
