based on the above, when the rectifier bridge circuit and the NTC thermistor 22 are cooled by the cooling fan 23, cold air is sucked from the heat dissipation holes 211 to cool the rectifier bridge circuit and the NTC thermistor 22, the dust removal filter screen 212 is driven to slide downwards, and then when the generator stops working, the dust removal filter screen 212 is driven to slide upwards by the expansion spring 213, and the dust removal filter screen 212 is cleaned by lapping the dust removal ring 214 with the limiting sliding groove formed in the protection bracket 21 to bounce dust in the dust removal filter screen 212, so that the effect of conveniently cleaning the dust removal filter screen 212 is achieved;
based on the above-mentioned further, NTC thermistor 22 and rectifier diode 11 series connection, just NTC thermistor 22 and radiator fan 23 parallel connection, NTC thermistor 22 is the thermistor that the temperature risees the resistance reduction, when NTC thermistor 22 resistance descends, can make radiator fan 23 and NTC thermistor 22's parallel circuit total resistance reduce, thereby improve radiator fan 23's power, accelerate the cooling operation to NTC thermistor 22, reduce the temperature of NTC thermistor 22 and rectifier bridge circuit, make NTC thermistor 22 resistance rise, thereby rise the voltage at NTC thermistor 22 both ends, slow down the voltage that rectifier diode 11 both ends received in the rectifier bridge circuit and lead to being broken down owing to undulant, influence automobile generator's normal electricity generation.
