Title: NON-CONTACT CHARGING DEVICE
Abstract:
A non-contact charging device, comprising: a transmitting terminal (3) and a receiving terminal (2). The receiving terminal (2) is electrically connected with a device to be charged (1). The receiving terminal (2) comprises a constant current control circuit (201). When the voltage of a battery of the device to be charged (1) is less than a preset value, the receiving terminal (2) outputs a 0.7-1.2 C constant current to the device to be charged (1). Non-contact charging is carried out by the transmitting terminal (3) and the receiving terminal (2), so that the device to be charged (1) does not need a cable port, and the waterproof and dustproof effect can be achieved; the charging process has no cable limit, thereby preventing users from directly contacting a high-voltage power supply; and the constant current control circuit (201) of the receiving terminal (2) outputs the 0.7-1.2 C constant current to the device to be charged (1), and a low-voltage high-current charging mode can improve charging speed, so that the charging time of the device to be charged (1) is reduced.
