Abstract: The present disclosure discloses an electric heating blanket. The electric heating blanket includes a rectangular electric heating blanket body with an electric heating layer laid inside. A connector which is electrically connected to the electric heating layer and a silicon key is fixed to the central position on the electric heating blanket body. The silicon key is sewn on the electric heating blanket body to facilitate operation and avoid a solution of directly operating by a controller, so that the electric heating blanket is more convenient and fast to use. The electric heating layer and the silicon key are electrically connected to the connector. The connector is connected to a plug through the controller. The controller is used for controlling heating output of the electric heating layer, and exchanging electric heating blanket state information and user control information with the silicon key through the connector.

Abstract: The present disclosure discloses a heated throw. The heated throw includes: a rectangular shawl body with an electric heating layer laid inside. A connector which is electrically connected to the electric heating layer and a silicon key is fixed to a position, relatively close to a corner, on the shawl body. The silicon key is sewn on the shawl body to facilitate an operation and avoid a solution of directly operating by a controller, so that the heated throw is more convenient and fast to use. The electric heating layer and the silicon key are electrically connected to the connector. The connector is connected to a plug through the controller. The controller is used for controlling heating output of the electric heating layer, and exchanging heated throw state information and user control information with the silicon key through the connector.

Abstract: The present disclosure relates to a control circuit for an electric blanket. The control circuit includes a main control circuit composed of a relatively low voltage power conversion circuit, a heating main loop, a micro control unit (MCU) main control circuit, an active/passive protection circuit and a main power carrier serial port circuit. The control circuit further includes a sub-control circuit. The sub-control circuit is composed of an auxiliary power carrier serial port circuit, a sub-control power extraction circuit, an MCU sub-control circuit, a function key input circuit and a display circuit. The main control circuit and the sub-control circuit exchange operating state information and user control information through the main power carrier serial port circuit and the auxiliary power carrier serial port circuit to implement heating control of the electric blanket in a mutually cooperative control mode.
