Currently, some household appliances, such as water heaters, warm air blowers, etc., are provided with circuit breakers. The circuit breaker is connected to the main circuit for cutting off power supply when abnormal conditions occur, so as to protect safety of household appliances and users.

In the related art, a temperature control circuit breaker is often arranged on a household appliance, for example, a temperature control circuit breaker is often arranged on an inner container of an electric water heater, and the temperature control circuit breaker is generally connected with a main circuit and cuts off power supply of a heating tube when the temperature is too high. The traditional temperature control circuit breaker mainly comprises a liquid expansion type temperature controller and a kick type temperature controller, wherein the liquid expands when the liquid is heated, and the diaphragm deforms under the internal pressure to push the power supply conducting end to move so as to cut off the connection between the main power supply and the load; the latter is that after heat is transferred to the memory metal, the metal sheet is deformed to push the power conducting end to move so as to cut off the connection between the main power source and the load.

However, the temperature control circuit breaker has a single function, and can only passively disconnect the circuit under the condition of abnormal temperature, and other circuit breakers are required to be additionally arranged for power-off protection aiming at other abnormal conditions.

For example, the temperature sensing structure 511 includes a temperature sensing terminal and a temperature sensing cavity, the temperature sensing cavity is filled with a solution, the movement structure 513 includes a membrane disposed at one side of the temperature sensing cavity, the temperature sensing terminal is used for conducting heat, and the solution absorbs heat and expands, so that the membrane at one side of the temperature sensing cavity moves; the moving structure 513 may also be a memory metal, which deforms after absorbing heat, and the deformed portion is formed as the movable end. The electric signal triggering assembly 53 includes a signal receiving structure for receiving a triggering signal, and an electromagnetic structure including a housing 531 and a magnetic member 533, the housing 531 being provided with a receiving cavity having one side opened, the magnetic member 533 being movably disposed in the receiving cavity.

The electric signal trigger component 53 and the temperature control circuit component are arranged to perform circuit breaking operation, on the one hand, the electric signal trigger component 53 can also drive the conducting end 311 to move to break the circuit when receiving a temperature abnormality signal, so that the scheme of driving a single temperature control circuit breaker 100 further realizes a safety function, and potential safety hazards caused by the fact that the temperature control trigger component 51 fails and the circuit cannot be broken in time are avoided; on the other hand, the electrical signal triggering component 53 can also break the circuit when receiving the triggering signal, and the diversified triggering signal can realize the circuit breaking protection under various conditions, so that the functionality and convenience of the circuit breaker 100 are improved.

In the embodiment, the temperature control trigger assembly 51 and the electric signal trigger assembly 53 are adopted to drive the same motion assembly to move so as to drive the conducting end 311, reduce the design and processing difficulty and ensure better motion consistency.
