In the embodiment of the present invention, the bottom surface connecting frame of the base 100 is provided with a first through hole 110 for limiting the moving track of the first pushing rod 720 at the middle position of the connecting frame. The sheet metal base 701 is attached (e.g., bolted, welded, or glued) to the bottom surface of the base. The metal sheet 710 is circular, and the center of the metal sheet 710 is connected with the bottom of the first push rod 720. The first protrusion 731 is located below the first movable contact 260, the second protrusion 732 is located below the second movable contact 270, one upward side (a surface connected to the bottom of the first push rod 720) of the metal piece 710 is a concave arc surface, and the other downward side of the metal piece 710 is a convex arc surface. The metal materials of the upward side and the downward side of the metal sheet 710 are different, the metal sheet 710 is used for sensing whether the ambient temperature exceeds a preset maximum temperature, when the ambient temperature exceeds the preset maximum temperature, the metal sheet 710 can generate overheating deformation, for example, when the metal sheet 710 which can generate deformation at the ambient temperature of 85 ℃ is selected, the upward side of the metal sheet 710 is deformed into a convex arc surface at the moment, and the downward side of the metal sheet 710 is deformed into a concave arc surface; thus, an upward pushing force is generated by the reverse deformation of the metal sheet 710, so that the first pushing rod 720 moves upward, the second pushing rod 730 connected with the first pushing rod 720 moves accordingly, the first protrusion 731 and the second protrusion 732 at the two ends of the second pushing rod 730 correspondingly abut against the first movable contact 260 and the second movable contact 270, the first active contact 271 at the other end of the second movable contact 270 is separated from the first passive contact 231 at the other end of the switch elastic sheet 230, and the first electric contact sheet 240 and the second electric contact sheet 250 are powered off, thereby realizing the overheat protection of the electric heating element.

When the first electrical plug 240 and the second electrical plug 250 need to be reconnected, the metal piece 710 can be restored by pushing the first push rod 720 to move downwards, and then the first protrusion 731 and the second protrusion 732 are separated from the first movable contact 260 and the second movable contact 270, so that the first active contact 271 on the other end of the second movable contact 270 and the first passive contact 231 on the other end of the switch elastic piece 230 are contacted again, and the first electrical plug 240 and the second electrical plug 250 are powered.

Specifically, the connecting portion 320 is provided with a moving groove 321 adapted to the shape of the first pushing rod 720; the first push rod 720 passes through the moving slot 321 and is located on the supporting portion 310. When the first push rod 720 is pushed upwards by the metal sheet 710, the top of the first push rod 720 penetrates through the moving groove 321, and the moving groove 321 fixes the moving track of the first push rod 720.

As a further alternative, referring to fig. 10, the thermostat further includes a face shell 800 connected to the base 100 and a nut cover 900 connected to the adjusting nut 410 through the face shell 800; the periphery of the base 100 is provided with a plurality of buckles 120, and the face shell 800 is provided with a hanging lug 810 connected with the buckles 120.

Specifically, a scale area 820 is disposed on the face shell 800, the scale area 820 is used for identifying a numerical value, and when the adjustment nut 410 is adjusted by the nut cover 900, the tightness of the adjustment nut 410 and one end of the temperature sensing rod 420 is adjusted by adjusting to different numerical values. The on-off of the conductive assembly 200 in different temperature ranges can be realized by different tightness degrees between the adjusting nut 410 and one end of the temperature sensing rod 420. For example, if the value of counterclockwise rotation in the scale area 820 is 1 to 5, it is indicated that the value 1 corresponds to the state that one end of the adjusting nut 410 and one end of the temperature sensing rod 420 are screwed to the tightest (at this time, the right-handed rotation is the default screwing), the distance between the corresponding connecting portion 320 and the adjusting nut 410 is also the smallest, the adjusting nut 410 and the connecting portion 320 are in close contact (because one end of the alloy lead screw 430 is in the abutting state with the bottom surface of the base 100 at this time), at this time, when the alloy lead screw 430 senses the increase of the ambient temperature, the alloy lead screw 430 expands slightly, the alloy lead screw 430 drives the temperature sensing rod 420, the connecting portion 320 and the adjusting nut 410 to move downward, and the connecting portion 320 drives the power contact 330 to be pressed with the second passive contact 233, so as to separate the first active contact 271 and the first passive. Similarly, when the adjusting nut 410 rotates to a value of 5, the distance between the connecting portion 320 and the adjusting nut 410 is the largest, a certain gap is formed between the adjusting nut 410 and the connecting portion 320, when the alloy lead screw 430 senses that the ambient temperature is increased, the alloy lead screw 430 needs to expand greatly, the alloy lead screw 430 drives the temperature sensing rod 420, the connecting portion 320 and the adjusting nut 410 to move downwards, and the connecting portion 320 drives the power contact 330 to be pressed with the second passive contact 233, so as to separate the first active contact 271 from the first passive contact 231. Therefore, by adjusting the tightness degree between the adjusting nut 410 and the end of the temperature sensing rod 420, the temperature sensing element 400 can cut off the current of the conductive element 200 at different environmental temperatures.

More specifically, the face housing 800 is provided with a reset hole 830 corresponding to the position of the first push rod 720. When the overheating protection assembly 700 is activated due to an excessive ambient temperature, an external tool (such as tweezers) extending into the inner reset hole 830 can push the first push rod 720 to move downwards, so that the metal sheet 710 is restored to the original state, and the first electrical plug 240 and the second electrical plug 250 are powered again.

On the other hand, when the external environment rises, the alloy screw 430 expands, and one end of the alloy screw 430 cannot move due to abutting against the bottom surface of the base 100, at this time, the other end of the alloy screw 430 is not constrained, and then drives the other end of the temperature sensing rod 420 to move downward, and one end of the temperature sensing rod 420 drives the adjusting nut 410 to move downward due to being pulled, and then the connecting portion 320 simultaneously moves downward, so that the power contact 330 moves downward and is in press fit with the second passive contact 233, and further the first passive contact 231 and the first active contact 271 are separated, and the first electrical plug 240 and the second electrical plug 250 are powered off.

On the other hand, when the ambient temperature exceeds the preset maximum temperature, the metal sheet 710 may generate overheating deformation; the upward side of the metal sheet 710 is deformed into a convex arc surface, and the downward side of the metal sheet 710 is deformed into a concave arc surface; and then, an upward pushing force is generated by the reverse deformation of the metal sheet 710, so that the first pushing rod 720 moves upwards, the second pushing rod 730 connected with the first pushing rod 720 moves along with the first pushing rod, and the first protrusion 731 and the second protrusion 732 at the two ends of the second pushing rod 730 correspondingly abut against the first movable contact 260 and the second movable contact 270, so that the first active contact 271 at the other end of the second movable contact 270 is separated from the first passive contact 231 at the other end of the switch elastic sheet 230, so that the first electric plug sheet 240 and the second electric plug sheet 250 are powered off, and the overheating protection of the electric heating body is realized.
