[0034] See also Figure 1-Figure 12 , is a schematic diagram of the structure of a high temperature resistant manual reset thermostat provided in an embodiment of the present application, comprising: a housing 1, a moving contact mounting frame 2, a moving contact 3, a fixed contact 4, a temperature sensing cover 5, a guide frame 7, a disc 8, an action rod 9, a fixed contact mounting frame 10, a first conductive member 11, a second conductive member 14, a first terminal 12 and a second terminal 13. Among them, the housing 1, the guide frame 6 and the action rod 9 are insulating members, which can be made of insulating materials; the moving contact mounting frame 2, the moving contact 3, the fixed contact 4, the fixed contact mounting frame 10, the first conductive member 11, the second conductive member 14, the first terminal 12 and the second terminal 13 are all conductive members, which can be made of metal materials due to the transmission or output of electrical signals. The thermostat also includes a reset handle 17, one end of which is arranged outside the housing 1, and the other end extends into the interior of the housing 1, and the reset handle 17 is used to realize the manual reset of the temperature control switch.

[0035] The housing 1 is an insulating support member of the temperature controller and can be made of an insulating 95 porcelain material. An upwardly open accommodation space 101 is formed inside the housing 1. A first mounting plane 102 for mounting the moving contact mounting frame 2 and a second mounting plane 104 for mounting the fixed contact mounting frame 10 are arranged in the accommodation space 101. The second mounting plane 104 is higher than the first mounting plane 102, so that the fixed contact 4 is arranged directly above the moving contact 3 in the accommodation space 101. A first mounting hole 103 that runs through the inside and outside of the housing 1 is arranged on the first mounting plane 102. The first mounting hole 103 is used to arrange the first conductive member 11. The first conductive member 11 extends out of the housing 1 through the first mounting hole 103 to connect to the first terminal 12. A second mounting hole 105 that runs through the inside and outside of the housing 1 is arranged on the second mounting plane 104. The second mounting hole 105 is used to arrange the second conductive member 14. The second conductive member 14 extends out of the housing 1 through the second mounting hole 105 to connect to the second terminal 13. A guide groove 106 penetrating the inside and outside of the shell 1 is also provided at the bottom center of the shell 1 for installing the reset handle 17 . The cross section of the guide groove 106 is cross-shaped and is designed to match the reset handle 17 .

[0036] The moving contact mounting frame 2 is used to mount the moving contact 3 and the first conductive member 11, and realize the electrical connection between the moving contact 3 and the first conductive member 11. Specifically, the moving contact mounting frame 2 includes a first mounting frame 201 and a second mounting frame 202. The first mounting frame 201 is provided with a moving contact mounting hole 203, and the moving contact 3 can be fixed in the moving contact mounting hole 203 by riveting; the second mounting frame 202 is provided with a first conductive member mounting hole 204, and the first conductive member 11 sequentially passes through the first conductive member mounting hole 204 and the first mounting hole 103 and extends out of the housing 1. The second mounting frame 202 is fixedly arranged on the first mounting plane 102 of the housing 1, and the first mounting frame 201 is arranged above the second mounting frame 202 and below the second mounting plane 104 of the housing 1, so that the moving contact 3 is located just below the fixed contact 4. The first mounting frame 201 is a thin plate, one end of which is connected to the second mounting frame 202 and is a fixed end, and the other end is a movable end. The movable end of the first mounting frame 201 can realize elastic deformation relative to its fixed end. The moving contact 3 is arranged on the movable end of the first mounting frame 201. Under the elastic force of the first mounting frame 201, the moving contact 3 can move up and down to realize contact or separation with the fixed contact 4, thereby realizing the closing and disconnection of the temperature control switch. Preferably, a pressure block 15 can also be arranged between the second mounting frame 202 and the first conductive member 11. The pressure block 15 is made of conductive material, such as H65T. The pressure block 15 is used to increase the force-bearing area of ​​the second mounting frame 202 to prevent the first conductive member 11 from having poor contact with the second mounting frame 202 during repeated deformation of the first mounting frame 201, thereby affecting the output of electrical signals. Please refer to Figure 8 , the first mounting frame 201 is a thin sheet. Under normal conditions, the first mounting frame 201 forms an upwardly inclined angle relative to the second mounting frame, and the moving contact mounting frame 2 is installed in the housing 1. When the thermostat is in a closed state, the first mounting frame 201 is in a pre-tightened state of downward compression, so that the moving contact 3 is more closely abutted against the fixed contact 4 under the elastic pre-tightening force of the first mounting frame 201. In order to facilitate the installation and positioning of the moving contact mounting frame 2, the first side surface 207 of the second mounting frame 202 that cooperates with the inner surface of the housing 1 is designed to be accompanied by the inner surface of the housing 1. In this embodiment, the housing 1 is cylindrical, and the first side surface 207 of the second mounting frame 202 close to the inner wall of the housing 1 is correspondingly designed as an arc surface, so as to facilitate the positioning and installation of the moving contact mounting frame 2. In this embodiment, the moving contact mounting frame 2 is made of copper-nickel-tin alloy, so that the moving contact mounting frame 2 has good electrical conductivity and high temperature resistance, so that the thermostat of this application can have better durability and service life in high temperature (250°C) application scenarios.

[0037] The moving contact 3 and the fixed contact 4 are electrical components used to realize the closing / opening of the thermostat switch, and can be made of AgNi 10Made of composite material with Cu to enhance the conductive properties.

[0038] The guide frame 7 is fixedly mounted on the upper end of the housing 1, and is used to mount the disc 8 and the actuating rod 9. Specifically, a guide hole 701 is provided through the center of the guide frame 7, and the actuating rod 9 is movably mounted in the guide hole 701, and can reciprocate up and down along the guide hole 701. A disc groove 702 is provided above the guide hole 701, and the disc 8 is arranged in the disc groove 702. A deformation space for the disc 8 is formed between the disc groove 702 and the temperature-sensitive cover 5; after the guide frame 7 is mounted on the upper end of the housing 1, the disc 8 and the first mounting frame 201 of the moving contact mounting frame 2 are respectively arranged at both ends of the actuating rod 9, and the disc 8 is an upwardly convex arc surface (such as Figure 1 or Figure 2 As shown in FIG. 1 ), the moving contact 3 contacts the fixed contact 4 under the elastic preload force of the first mounting frame 201, so that the temperature control switch is closed; when the disc 8 is heated to the customized temperature, it quickly moves downward and turns into a concave arc surface (such as Figure 3 As shown in the figure, the disc 8 pushes the action rod 9 to slide downward along the guide hole 701, and the lower end of the action rod 9 pushes it downward by abutting against the first mounting frame 201, so that the moving contact 3 is separated from the fixed contact 4, and the temperature control switch is disconnected. When the temperature drops again, the disc 8 cannot be reset automatically. At this time, by pushing the reset handle 17 at the bottom of the thermostat upward, the reset handle 17 drives the first mounting frame 201 and the action rod 9 to move upward in turn, so that the disc 8 is reset. Preferably, a contact portion 206 is convexly provided on the first mounting frame 201, which is used to form a match with the lower end of the action rod 9. The side of the contact portion 206 facing away from the action rod 9 forms a concave surface, which is used to form a match with the top of the reset handle 17. The second mounting frame 202 is provided with a through hole 205 for the reset handle 17 to pass through. The reset handle 17 passes through the above-mentioned through hole 205 and abuts against the back of the contact portion 206, thereby driving the action rod 9 to slide. The reset handle 17 does not contact the second mounting frame 202 during the operation.

[0039] The fixed contact mounting frame 10 is fixedly arranged on the second mounting plane 104, and is used to mount the fixed contact 4 and the second conductive member 14, and realize the electrical connection between the fixed contact 4 and the second conductive member 14. The fixed contact mounting frame 10 can be a thin plate, and the second side surface 1003 of the fixed contact mounting frame 10 that matches the inner surface of the housing 1 is designed as an arc surface that matches the inner surface of the housing 1, and is just clamped on the inner wall of the housing 1, so as to facilitate the positioning and installation of the fixed contact mounting frame 10. The fixed contact mounting frame 10 is provided with a second conductive member mounting hole 1002 and a fixed contact mounting hole 1001, and the fixed contact 4 can be fixed in the above-mentioned fixed contact mounting hole 1001 by riveting, and the second conductive member 14 passes through the above-mentioned second conductive member mounting hole 1002 and the second mounting hole 105 of the housing 1 in sequence to extend out of the housing 1 to connect the second wiring terminal 13.

[0040] The temperature sensing cover 5 is arranged above the disc 8 and covers the upper end of the housing 1, which plays a role in heat conduction on the one hand and is used to achieve the packaging of the accommodating space 101 on the other hand. When the thermostat is installed on the heating element, the temperature sensing cover 5 senses the temperature, causing the disc 8 to deform due to heat.

[0041] To achieve the connection between the temperature sensing cover 5 and the housing 1, a flange structure 107 may be provided at the upper end of the housing 1, and the temperature sensing cover 5 may be installed by buckling and clamping the temperature sensing cover 5 onto the flange structure 107. In this embodiment, the temperature sensing cover 5 may be made of LF2-M aluminum-magnesium alloy material.

[0042] Preferably, a gasket 6 is provided between the temperature-sensing cover 5 and the guide frame 7. The gasket 6 is annular and serves as a support member after the disc 8 is deformed. The inner diameter of the gasket 6 is slightly smaller than the diameter of the disc 8. After the disc 8 is deformed, its edge just abuts against the gasket 6 to form a support.

[0043] In order to realize the installation of the thermostat, the thermostat also includes an external bracket 16, which is fixed on the temperature sensing cover 5. The external bracket 16 is used to fix the thermostat on the heating element. The external bracket 16 includes a third mounting plane 1601. The third mounting plane 1601 can be arranged parallel to the temperature sensing plane 501 of the temperature sensing cover 5. In this way, after the thermostat is installed through the external bracket 16, it can be made not affected by the installation angle, and the temperature sensing plane 501 can realize good temperature sensing.

[0044] The reset handle 17 for manually resetting the disc 8 includes a handle portion 1701 and a reset portion 1702. The handle portion 1701 cooperates with the guide groove 106 on the shell 1, and its cross-section is designed to be a cross shape; the reset portion 1702 is a columnar rod, and its top cooperates with the upper concave surface at the bottom of the contact portion 206 on the moving contact mounting frame 2, and can be designed as a smoothly transitioned arc surface.

[0045] In this embodiment, in order to improve the high temperature resistance of the temperature controller, the moving contact mounting frame 2, the first conductive member 11 and the second mounting frame 14 are all made of copper-nickel-tin alloy. The temperature controller of the present invention can continue to work reliably after working continuously for 500 hours in an environment of 250°C.

[0046] The specific implementation methods of this application are as follows:

[0047] First, the moving contact 3, the pressing block 15, and the first conductive member 11 are mounted on the moving contact mounting frame 2, and the fixed contact 4 and the second conductive member 14 are mounted on the fixed contact mounting frame 10. Then, the moving contact mounting frame 2, the fixed contact mounting frame 10, the guide frame 7, the actuating rod 9, the disc 8 and other components are sequentially mounted in the housing 1 to form the main structure of the thermostat. Next, the gasket 6 and the temperature-sensing cover 5 are mounted above the disc 8, and then the thermostat is mounted on the heating element through the external bracket 16.

[0048] The working principle of this thermostat is as follows: the temperature sensing cover 5 senses the temperature, and the disc 8 suddenly moves after absorbing heat to the customized temperature, pushing the action rod 9 to move, so that the action rod 9 moves down along the guide hole 701, pushing the first mounting frame 201 of the moving contact mounting frame 2 to deform downward, so that the moving contact 3 is separated from the fixed contact 4, and the temperature control switch disconnects the circuit. After the circuit where the thermostat is located is disconnected, the heating element no longer works, the temperature of the heating element drops, and the disc 8 still does not reset after the temperature drops. It is necessary to manually press the reset handle 17, and the reset handle 17 slides upward, passes through the through hole 205 and abuts against the first mounting frame 201, so that the first mounting frame 201 is deformed upward, and then pushes the action rod 9 to slide upward, so that the disc 8 flips upward and resets; at the same time, the moving contact 3 re-contacts the fixed contact 4 under the elastic force of the first mounting frame 201, so that the thermostat is reset and connected, and the heating element starts to heat again.
