[0020] Figure 5 This is a perspective view of a rotating component according to an embodiment of the present invention. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings: As shown in the figures, a temperature controller includes a base 1 and a support plate 2. A temperature sensing element 3 is provided on the support plate. An energy storage rod 11 and a rotatably mounted transmission rod 12 are provided on the base. The transmission rod includes a first position that is limited and cooperates with the energy storage rod and a second position that is separated from the energy storage rod. When the temperature sensing element is heated beyond a threshold, it deforms and drives the transmission rod to the second position. The controller also includes a mounting base 4, which is provided on the base; and an elastic rod 5, one end of which is connected to the mounting base and the other end of which presses against the transmission rod to drive the transmission rod to the first position.

[0022] For details on how the energy storage rod and the transmission rod work together, please refer to Chinese Patent No. CN113712429B. This application is characterized by replacing the existing energy storage rod that uses a spring for pre-tensioning with an elastic rod for pre-tensioning. This solves the problem of springs easily twisting. The temperature sensing element can be a bimetallic strip, etc. The use of an elastic rod will not cause twisting, resulting in smooth operation and good performance.

[0023] In this embodiment, as shown in the figure, the mounting base is provided with a mounting groove 41. The elastic rod includes an integrally formed mounting part 51 and a pressing part 52. The mounting part is connected to the mounting groove, and the pressing part presses against the transmission rod. The mounting part can be installed to the inner wall of the mounting groove by means of snap-fit ​​or other methods. After installation, the pressing part presses against the transmission rod by elastic force, so that it is in a pre-tightened and limited position. However, under the action of the temperature sensing element, the transmission rod will still rotate to separate from the energy storage device. Preferably, a rotating shaft 120 is provided at the middle end of the transmission rod, and the force of the temperature sensing element and the elastic rod is on both sides of the rotating shaft.

[0024] In this embodiment, as shown in the figure, the side wall of the transmission rod is provided with a fixing groove 121, and part of the pressing part is provided in the fixing groove.

[0025] In this embodiment, as shown in the figure, the mounting part has a U-shaped structure. The mounting groove includes a communicating opening groove 411 and a positioning groove 412. The mounting part is disposed in the positioning groove and engages with the inner wall of the positioning groove. The opening groove is used for the mounting part to extend into, and the positioning groove is used for fixing the mounting part. The mounting part has an overall U-shaped structure, and its two outer walls contact the two inner walls of the positioning groove to achieve fixation.

[0026] In this embodiment, as shown in the figure, the opening slot is provided on the side wall of the mounting base for easy installation.

[0027] In this embodiment, as shown in the figure, the transmission rod includes a rod body, and a boss 122 is provided on the side wall of the rod body. The fixing groove is provided on the boss. The fixing groove is located on the upper end face of the boss, and the structure is stable after the pressing part is installed, making it difficult to fall out.

[0028] In this embodiment, as shown in the figure, the transmission rod is provided with a clearance groove 123, and at least part of the mounting seat is disposed in the clearance groove. The overall structure is compact and does not affect the operation of the transmission rod.
