Wireless power supply device

The invention relates to a wireless power supply device, which belongs to the field of wireless power supply and includes a transmitting device and a receiving device. The transmitting device is provided with a power supply module, a first rectification module, an oscillation source module, a control circuit module and a high frequency output The circuit module is electrically connected in turn, one side of the transmitting device is connected to the transmitting coil, the control circuit module is provided with a control key module, an encoding module, a modulation module and a power amplification module from top to bottom, and the receiving device is connected to the A demodulation module, a second rectification module and a receiver are provided from left to right, and are electrically connected in sequence. A receiving coil is provided on one side of the receiving device, and a detection module is connected to one side of the high-frequency output module. The detection module The outer wall is provided with an LED display screen, and the other side of the detection module is electrically connected to the control circuit module. The present invention automatically detects whether the receiving part is working through the detection module, and only when it is detected that the receiver is working will it continuously radiate wireless energy, which is practical Strong.
