Abstract
A fast charging circuit for adult toys includes a charging control unit, where the charging control unit is configured to perform charging control of a rechargeable battery with a charging rate of not less than 1 C, and the charging control unit employs a battery fast-charging management chip. A constant current parameter setting loop is disposed at a current control terminal of the battery fast-charging management chip and configured to switch and/or set current parameters for a constant current charging process. An enable control loop is disposed at an enable terminal of the battery fast-charging management chip. In this way, the present disclosure achieves precise control of charging current, and greatly shortens the charging duration, such that the user does not need to wait for completion of an entire charging process or a long charging duration, but may charge the adult toy in fragmented time.
