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, thereby solving the problem that the motor of the ventilating fan is at high temperature for a long time

Abstract

The invention discloses a triode voltage stabilized type energy-saving control circuit for a ventilator. The triode voltage stabilized type energy-saving control circuit is mainly composed of a diode rectifier U, an amplifier P, a field-effect transistor MOS, a unidirectional thyristor VS, a thermistor RT, a switch SW, a triode VT1, a triode VT2, a triode VT3, a triode VT4, a resistor R9, a polar capacitor C5, a resistor R12 with one end connected with the anode of the unidirectional thyristor VS and the other end grounded, and the like. The thermistor RT is a polymer PTC thermistor which has the characteristic of a resettable fuse, and current applied to the thermistor RT can be adjusted, so that the thermistor RT is combined with peripheral current, intermittent power supplying to the ventilator can be well achieved, and the problem that a motor of the ventilator is at a high temperature for a long time is effectively solved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a triode voltage stabilizing energy-saving control circuit for a ventilating 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...
