[0029] A base body 1 is connected to a mounting bracket 2, a touch assembly is provided on the base body 1, and the touch assembly includes a static contact piece 3 fixedly connected to the base body 1, and a contact end of the static contact piece 3 abuts against a dynamic contact piece 5, and a mounting hole is opened on the mounting bracket 2;

[0030] The temperature control component is fixedly arranged in the mounting hole.

[0031] It can be seen from this embodiment that the base 1 is the basic structure of the thermostat. A touch component is provided on the base 1 for realizing on-off control of the circuit. The touch component includes a static contact piece 3 and a dynamic contact piece 5 directly fixed to the base 1. The static contact piece 3 and the dynamic contact piece 5 are directly fixed to the base 1 to prevent poor contact of equipment such as tea makers and electric kettles after long-term use. A mounting bracket 2 is connected to the base 1 for supporting and fixing other components. A mounting hole is provided on the mounting bracket 2 for installing the temperature control component. The temperature control component is used to control the movement of the dynamic contact piece 5 in the touch component.

[0038] The push rod 9 has one end that abuts against the moving contact piece 5 , and the other end that passes through the guide frame 7 and abuts against one end of the temperature control spring 8 .

[0039] The guide frame 7 is tightly fitted in the temperature sensing cap 6 and is used to guide the movement of the push rod 9 and ensure the position of the temperature control spring 8. The temperature control spring 8 is arranged between the guide frame 7 and the temperature sensing cap 6. The temperature control spring 8 will deform as the temperature rises, thereby pushing the push rod 9 to move. One end of the push rod 9 is against the moving contact piece 5, and the other end passes through the guide frame 7 and is against one end of the temperature control spring 8, which is used to convert the deformation of the temperature control spring 8 into the movement of the moving contact piece 5, so that the moving contact piece 5 is separated from the static contact piece 3, the circuit is powered off, and the temperature control spring 8 will shrink back to its original shape after the temperature drops. The circuit is closed again for heating. The on and off of the circuit is controlled by the deformation of the temperature control spring 8, so that the water temperature of equipment such as tea makers and electric kettles can be controlled. The temperature control spring 8 can be made of materials with different thermal expansion coefficients according to different temperature requirements.
