They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted, connected, and connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0026] Reference Figure 1 and Figure 2, an embodiment of the present application provides a temperature controller, including: a base 100, provided with a wiring terminal 110, the wiring terminal 110 is made of a first composite conductive material; a spring assembly, arranged on the base 100, the spring assembly includes a moving contact piece 210 and a static contact piece 220, the moving contact piece 210 and the static contact piece 220 are made of a second composite conductive material, the moving contact piece 210 and the static contact piece 220 are respectively connected to the wiring terminal 110, and the moving contact piece 210 can contact or move away from the static contact piece 220; a temperature sensing component, arranged above the base 100, the temperature sensing component is used to drive the moving contact piece 210 and the static contact piece 220 to contact or move away.

[0027] By making the connecting terminal 110 of a first composite conductive material and making the moving contact piece 210 and the static contact piece 220 of a second composite conductive material, the manufacturing cost of the temperature controller can be reduced. At the same time, it can also ensure that the connecting terminal 110 and the moving contact piece 210 and the static contact piece 220 have good conductive properties and meet the production process requirements.

[0028] The first composite conductive material comprises an iron layer and a first copper layer, with the first copper layer wrapped around the iron layer. The second composite conductive material comprises a steel layer and a second copper layer, with the steel layer wrapped around the second copper layer. This structure reduces copper usage and manufacturing costs while also ensuring the thermostat's electrical conductivity, meeting production process requirements.

[0029] It should be noted that the first composite conductive material and the second composite conductive material may also be a composite material of aluminum and copper or other composite materials, and those skilled in the art may make reasonable choices based on actual conditions, and this application does not impose any restrictions on this.

[0030] Reference Figure 1 and Figure 2In this embodiment, the temperature sensing assembly includes a push rod 310, a bimetallic strip 320, and a cover 330. The bottom end of the push rod 310 is connected to the movable contact 210, the bimetallic strip 320 is located at the top end of the push rod 310, and the cover 330 is located above the bimetallic strip 320. The cover 330 is connected to the base 100. During operation, the movable contact 210 and the stationary contact 220 come into contact, the circuit is connected, and heating begins. When the temperature reaches the set temperature of the bimetallic strip 320, the bimetallic strip 320 deforms and bulges toward the push rod 310, causing the push rod 310 to descend and press against the movable contact 210. The movable contact 210 and the stationary contact 220 separate, the circuit is disconnected, and heating stops. As the temperature decreases, the bimetallic strip 320 gradually returns to its original shape, causing the push rod 310 to rise, and the movable contact 210 and the stationary contact 220 re-contact, the circuit is connected, and heating resumes. The movable contact piece 210 is provided with a movable contact point, and the stationary contact piece 220 is provided with a stationary contact point. The movable contact point can contact or separate with the stationary contact point, thereby improving the stability and reliability of the connection between the movable contact piece 210 and the stationary contact piece 220.

[0031] It can be imagined that the base 100 is provided with a socket 120, which is used to set a pin. At this time, the pin can be inserted into the base 100 from the socket 120 to press the moving contact piece 210, so that the moving contact piece 210 contacts the static contact piece 220 to achieve circuit conduction, thereby achieving manual reset, with a simple structure and easy operation.

[0032] Reference Figure 1 and Figure 2 Furthermore, the base 100 is provided with a guide frame 130, and the temperature sensing component is provided on the guide frame 130. The guide frame 130 is provided with a guide hole 140, and the top rod 310 is passed through the guide hole 140. By providing the guide frame 130, the movement of the top rod 310 can be guided, preventing the top rod 310 from deflecting, improving stability, and improving safety performance. It is easy to understand that the guide frame 130 is provided with a groove, which can ensure that the bimetallic strip 320 has sufficient operating space, ensuring the stability and reliability of the bimetallic strip 320.

[0033] As can be imagined, the cover 330 is connected to the base 100 by rolling the edges around, which has a simple structure and is easy to operate. Specifically, the outer wall of the base 100 is provided with a clamping block to enhance the stability of the connection between the cover 330 and the base 100. Furthermore, the cover 330 is provided with a through hole 340, through which the bimetallic strip 320 extends, facilitating contact between the bimetallic strip 320 and the temperature-measured portion, improving heat transfer efficiency, and enhancing the stability and reliability of the bimetallic strip 320.

[0034] It should be noted that the cover 330 may not be provided with the through hole 340. In this case, in order to ensure that the bimetallic strip 320 can respond to the temperature in a timely manner, the cover 330 can be made of copper or aluminum. Furthermore, the cover 330 is set to be made of copper. By setting the cover 330 to be made of copper, the cover 330 made of copper has a higher thermal conductivity than the cover 330 made of aluminum, which can allow heat to be transferred to the bimetallic strip 320 faster through the cover 330, so that the bimetallic strip 320 can sense the temperature change faster, and has higher detection accuracy for temperature detection during extreme heating, so that the bimetallic strip 320 can respond to temperature changes in a timely manner.

[0035] Reference Figure 1 and Figure 2 As will be readily understood, cover 330 is provided with mounting lugs 350, each of which is provided with mounting holes 360. The provision of mounting holes 360 facilitates connection between the thermostat and external components, resulting in a simple structure and easy operation. Furthermore, mounting holes 360 are configured as adjustment holes, eliminating the need for precise positioning, reducing manufacturing complexity and improving efficiency.

[0036] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

[0037] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
