[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8This utility model provides a technical solution for an automatic reset thermostat structure: an automatic reset thermostat structure includes a base assembly 1 and a cover assembly 3 that are encapsulated together. The base assembly 1 includes a bottom sealing seat 11. The inner wall of the support of the bottom sealing seat 11 is provided with a guide groove 13 in a U-shaped groove structure. By setting the guide groove 13 as a U-shaped groove structure, it has a cyclic guiding characteristic, which can guide the locking handle 33 to slide in and slide out, realizing the locking handle 33 in the sliding-in locking and sliding-out unlocking states.

[0030] Each guide chute 13 has a locking slot 14 in the middle of its track groove. The cover assembly 3 includes a top cover 31. The edges of the top cover 31 are provided with opposing locking handles 33. The locking handles 33 are slidably connected to the guide chute 13, and the locking handles 33 and locking slots 14 are locked together. The locking handles 33 include a support 331 and a buckle 332 installed at the bottom of the support arm of the support 331. The buckle 332 and locking slots 14 are locked together. The sliding surface of 332 has an arc-shaped structure, and the buckle 332 and the locking groove 14 are interlocked. Through the buckle 332 in the locking handle 33, it slides along one side of the guide groove 13 while being interlocked into the locking groove 14, thus achieving the locking state between the base assembly 1 and the cover assembly 3. Furthermore, when subsequent disassembly or reassembly is required, by continuously pressing down on the cover assembly 3, the buckle 332 is pushed out of the locking groove 14 and slides along the bottom of the guide groove 13 (see the attached instruction manual). Figure 5 (As shown), then turn the knob cover assembly 3 so that the buckle 332 slides into the other side of the guide groove 13 (refer to the instruction manual). Figure 6 (As shown), and then simply lift the cap assembly 3 to detach the cap assembly 3 from the base assembly 1.

[0031] The bottom seal seat 11 has positioning feet 12 arranged on both sides of the support. The positioning feet 12, in conjunction with the positioning bolts, fix the bottom seal seat 11 to the corresponding equipment.

[0032] A knob 32 is provided on the top of the cover plate of the top cover 31. The knob 32 makes it easy for staff to press and turn the cover assembly 3.

[0033] The base assembly 1 and the cover assembly 3 are interlocked, and a sealing gasket 2 is provided between the base assembly 1 and the cover assembly 3. The sealing gasket 2 has a C-shaped structure and is made of natural rubber. By making the sealing gasket 2 a natural rubber material, it has good elastic deformation ability, so that when the cover assembly 3 and the base assembly 1 are locked together, the sealing gasket 2 is squeezed and deformed, and the interface between the cover assembly 3 and the base assembly 1 is tightly sealed to achieve its waterproof and moisture-proof functions. Furthermore, by making the sealing gasket 2 a C-shaped structure, during subsequent disassembly and assembly, only the sealing gasket 2 needs to be removed, providing continuous downward pressure space for the cover assembly 3, so that the cover assembly 3 can be pressed down and removed by turning the knob.

[0034] The thermostat body 4 is installed inside the support of the base assembly 1. The thermostat body 4 includes an upper and lower encapsulated outer shell 41 and a base plate 42. The bottom of the base plate 42 is provided with insulating paper 43. The inner shell of the outer shell 41 is connected to a bimetallic strip 45, and the outer shell 41 is fixedly connected to the bimetallic strip 45 by fixing nails 44. The bottom end of the spring of the bimetallic strip 45 is provided with a moving contact 46, and the upper part of the base plate 42 is provided with a stationary contact 47 opposite to the moving contact 46. When the thermostat structure is installed and used, when the ambient temperature reaches its set operating temperature, the bimetallic strip 45 jumps, and the moving contact 46 on the bimetallic strip 45 disengages from the stationary contact 47 on the base plate 42, thereby disconnecting the circuit and playing the role of over-temperature protection.

[0035] The working principle of this utility model is as follows: When assembling the thermostat in a modular manner, after the thermostat body 4 is placed inside the base assembly 1, the cover assembly 3 is pressed down and pushed into the base assembly 1 to match the base assembly 1. At the same time as the cover assembly 3 is pressed and sealed, the locking handle 33 on the cover assembly 3 deforms and slides along the guide groove 13 of the base assembly 1. Then, while pressing down the cover assembly 3, the buckle 332 of the locking handle 33 is pressed into the locking groove 14, realizing the locking state of the base assembly 1 and the cover assembly 3. While the base assembly 1 and the cover assembly 3 are encapsulated as a whole, the sealing gasket 2 is squeezed and deformed to tightly seal the interface between the cover assembly 3 and the base assembly 1, so as to realize its waterproof and moisture-proof functions and complete its modular assembly work.

[0036] Furthermore, during the subsequent installation and use of the temperature controller, the temperature controller body 4 is used to detect the temperature of the equipment. When the ambient temperature of the equipment reaches its set operating temperature, the bimetallic strip 45 jumps, and the moving contact 46 on the bimetallic strip 45 disengages from the stationary contact 47 on the base plate 42, thereby disconnecting the circuit and playing the role of over-temperature protection.

[0037] Furthermore, when subsequent disassembly and maintenance are required, by removing the sealing gasket 2, continuous downward pressure is provided for the cover assembly 3. Then, by continuously pressing down on the cover assembly 3, the buckle 332 is pushed out of the locking groove 14 and slides along the bottom of the guide slide 13. After sliding into the bottom of the groove, the cover assembly 3 is turned so that the buckle 332 slides into the other side of the guide slide 13. At this time, it is only necessary to lift the cover assembly 3 to disassemble and assemble the cover assembly 3 and the base assembly 1, and to perform maintenance on the internal thermostat body 4. The operation is simpler and more convenient.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
