Wireless charger, wireless charging system and wireless charging method

Abstract

The invention provides a wireless charger, a wireless charging system and a wireless charging method. The wireless charger comprises a housing, a circuit board, a soft magnetic plate and a transmitting coil; the circuit board, the soft magnetic plate and the transmitting coil are disposed in the housing; two opposite sides of the housing are respectively provided with a through hole; the wireless charger further comprises a temperature detection module, a controller and an air flow guiding module which are disposed in the housing; the temperature detection module detects temperature in the housing, and sends the detected temperature to the controller; the controller controls the air flow guiding module to be opened according to the temperature sent by the temperature detection module, and controls charging power of the wireless charger; and, when the air flow guiding module is opened, an air flow is guided to enter via the through hole in one side of the housing, bypass the circuit board, the soft magnetic plate and the transmitting coil and be discharged via the through hole in the other side. According to the wireless charger provided by the invention, in the charging process, the air flow guiding module enables the air flow to be formed in the wireless charger, and cooling for the inside of the wireless charger is achieved.
