Problems solved by technology
Due to the design of its internal control circuit, this kind of controller has a relatively large volume. When using the electric blanket, it is very inconvenient to connect the controller like dragging a burden, and it also affects the function of the entire blanket body. Beautiful, greatly reducing people's experience

Embodiment Construction
[0027] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] Figures 1 to 11 It is a circuit diagram of the present invention.
[0029]In the prior art, heating products such as electric heating blankets and heating pads will drag a cumbersome controller, which makes the use of such heating products very inconvenient. In order to make the heating products more convenient to use, and the blanket body lighter and more beautiful, it is necessary The traditional controller is redesigned, and the design of the controller is mainly its control circuit. For this reason, the present invention proposes a control method that uses the interaction between the main control and the auxiliary control to control the electric heating products that work normally. A blanket control circuit, the control circuit includes a main control circuit and a sub-control circuit, that is, a main control and a sub-control, and...

The invention discloses an electric blanket control circuit. The electric blanket control circuit comprises a main control circuit composed of a relative low-voltage power supply conversion circuit, aheating main loop circuit, an MCU main control circuit, an active and passive protection circuit and a main power supply carrier serial port circuit, and comprises an auxiliary control circuit; and the auxiliary control circuit is composed of an auxiliary power supply carrier serial port circuit, an auxiliary control power supply extraction circuit, an MCU auxiliary control circuit, a function key input circuit and a display circuit. The main control circuit and the auxiliary control circuit carry out mutual exchange of heating state information and control information through the main powersupply carrier serial port circuit and the auxiliary power supply carrier serial port circuit so as to realize heating control of an electric blanket in a mutual cooperation control mode. The controlmethod of the control circuit is simple, and the use experience of product operation can be better improved.
Description
technical field [0001] The invention relates to a temperature control technology of an electric heating body, in particular to a control circuit of an electric heating blanket. Background technique [0002] At present, traditional electric heating products such as heating pads and electric blankets at home and abroad are connected to a controller through a line, and the controller is connected to a power plug with a line. Due to the design of its internal control circuit, this kind of controller has a relatively large volume. When using the electric blanket, it is very inconvenient to connect the controller like dragging a burden, and it also affects the function of the entire blanket body. It is beautiful and greatly reduces people's experience in use. In order to make the operation and use of the electric heating blanket more convenient, it is necessary to redesign the control circuit of the electric heating blanket. Contents of the invention [0003] The technical pro...
