Document Type and Number:
WIPO Patent Application WO/2022/166256
Kind Code:
A1
Abstract:
Disclosed in the present invention are a battery charger cooling fan control circuit and a charger. The battery charger cooling fan control circuit comprises a charging controller, a signal distribution circuit, a charging circuit, a charging switch-on control circuit, a cooling fan and a fan switch-on control circuit, wherein the charging controller outputs a charging permission signal; after input into the signal distribution circuit, the charging permission signal is divided into two signals which are the same, one signal being connected to an input end of the charging switch-on control circuit, and the other signal being connected to an input end of the fan switch-on control circuit; an output end of the charging switch-on control circuit is connected to an input end of the charging circuit; and an output end of the fan switch-on control circuit is connected to the cooling fan. In the present invention, by means of controlling the cooling fan and a battery charger by means of the same control signal, a charging operation and a fan cooling operation are synchronously performed, thereby achieving the aims of saving power and reducing a dust suction volume.
