Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the ventilating fan in the prior art uses a continuous power supply type control circuit to supply power to the ventilating fan, which can only continuously supply power to the ventilating fan, so that the ventilating fan does not stop working, causing the motor of the ventilating fan to be in a high temperature state for a long time, and The defect of poor output voltage stability provides an energy-saving control circuit for ventilating fans that intermittently supplies power to the ventilating fan, which can improve the stability of the output voltage, thereby solving the problem that the motor of the ventilating fan is at high temperature for a long time and has poor speed stability.

Abstract

The invention discloses a voltage regulation type energy-saving control circuit for a ventilation fan. The voltage regulation type energy-saving control circuit for the ventilation fan mainly comprisesa diode rectifier U, an amplifier P, a field-effect transistor MOS1, a field-effect transistor MOS2, a unidirectional thyristor VS, a thermistor RT, a switch SW, a triode VT1, a triode VT2, a triode VT3, a resistor R9, a polar capacitor C5 and a resistor R12, wherein one end of the resistor R12 is connected with an anode of the unidirectional thyristor VS, and the other end of the resistor R12 is grounded. According to the voltage regulation type energy-saving control circuit for the ventilation fan disclosed by the invention, the thermistor RT is a high-polymer ptc thermistor which has the characteristics of a self-recovery fuse, the current applied to the thermistor RT can be regulated in such a manner that the thermistor RT is combined with the peripheral current, the discontinuous power supply to the ventilation fan can be realized in a better manner, and therefore the problem that an electric motor of the ventilation fan is at a high temperature for a long term is solved effectively.

Description

technical field [0001] The invention relates to the field of electronics, specifically, a voltage-adjustable energy-saving control circuit for a ventilation fan. Background technique [0002] The number of deaths due to carbon monoxide poisoning is increasing every year around the world, and poor air circulation is an important factor leading to carbon monoxide poisoning. In order to prevent the occurrence of carbon monoxide poisoning due to lack of air circulation, people have installed ventilation fans in places with small spaces such as toilets, corridors, and kitchens to ensure that the air in the room and the outside world circulate and reduce the carbon monoxide gas in the room. However, at present, people often use a continuous power supply control circuit as the control circuit of the ventilation fan. This continuous power supply control circuit will always supply power to the ventilation fan after it is turned on, so that the ventilation fan will continue to work, c...
