Abstract
An intelligent-identification quick-charge electric blanket includes an electric blanket body, a manual operation button module and a connecting cable for a quick charge power source. The connecting cable includes an input module, a cable body, and an output port. The input module includes an output control circuit, a main control circuit, a power supply circuit, and a USB interface. The electric blanket simplifies the structure of the electric blanket body. It is convenient for subsequent replacement of the quick charge identification function or the electric blanket body, thereby reducing the maintenance cost.
