Thermostat has a wide range of applications. Different types of thermostats are used in many products such as home appliances, motors, refrigeration or heating.

[0003] One end of the temperature sensing tube of the existing probe type thermostat is fixedly installed inside the shell, which means that the shell needs to be disassembled when replacing the temperature sensing tube, which is inconvenient. The patent document with the prior art publication number CN216671495U provides a fast-sensing probe type thermostat. When the temperature sensing tube needs to be replaced, the device only needs to rotate the temperature sensing tube so that the plug on the temperature sensing tube is away from the slot of the mounting block, so that the temperature sensing tube can be directly pulled out, which is convenient for disassembly and replacement of different types of temperature sensing tubes.

[0004] The device ensures the sealing between the temperature sensing tube and the shell by a sealing ring, resulting in a protruding plug at the end of the temperature sensing tube that restricts the movement of the temperature sensing tube. The shell still needs to be disassembled, which has low practicality. Therefore, a fast temperature sensing thermostat is urgently needed to solve the above problem. Utility Model Content

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a fast temperature-sensing thermostat, which includes a shell 1 and a temperature-sensing element installed inside. A temperature-sensing tube 2 is connected to the shell 1, and a plurality of arc-shaped clamping plates 3 are elastically connected to one end of the shell 1. The arc-shaped clamping plates 3 are in abutment with the temperature-sensing tube 2, and a temperature-conducting plate 6 connected to the temperature-sensing element is installed in the shell 1. One end of the arc-shaped clamping plate 3 is connected to the temperature-conducting plate 6. A driving mechanism 5 is connected to the shell 1, and the driving mechanism 5 is used to drive the arc-shaped clamping plate 3 to move.

[0028] In the above technical scheme, the arc clamping plate 3 and the temperature conduction plate 6 are both made of heat-conducting metal materials. The driving mechanism 5 can drive the arc clamping plates 3 to move synchronously. Each arc clamping plate 3 clamps the temperature sensing tube 2 and is connected to the temperature conduction plate 6 at the same time, so that the temperature sensing tube 2 transfers the heat of the detected object to the temperature conduction plate 6 through the arc clamping plate 3, and judges the temperature of the detected object through the temperature sensing element.

[0029] The driving mechanism 5 includes a driving ring 501 threadedly matched with the shell 1, and a plurality of wedge blocks 505 are slidably connected to the driving ring 501. One side of the wedge block 1 505 is slidably contacted with a wedge block 2 506, and the wedge block 2 506 is fixedly connected to the arc clamping plate 3. When the driving ring 501 rotates on the shell 1, it can drive the wedge block 1 505 to move vertically. When the wedge block 1 505 and the wedge block 2 506 are abutted and matched, the arc clamping plate 3 can abut against the temperature sensing tube 2. When the wedge block 1 505 is not abutted against the wedge block 2 506, the arc clamping plate 3 cancels the abutment against the temperature sensing tube 2.

[0030] Both ends of the arc-shaped clamping plate 3 are elastically connected to the inner wall of the shell 1 through springs 4. Multiple arc-shaped clamping plates 3 are arranged in a ring with equal intervals. When not subject to external force, the spring 4 drives the arc-shaped clamping plate 3 to approach the inner wall of the shell 1. At this time, the diameter of the multiple arc-shaped clamping plates 3 is larger than the diameter of the temperature sensing tube 2, so that the temperature sensing tube 2 can be inserted into the interior through one end of the shell 1.

[0031] An arc-shaped strip 301 is fixedly provided on the side of the arc-shaped clamping plate 3 facing the temperature sensing tube 2, and an annular groove 201 matching with the arc-shaped strip 301 is opened on the temperature sensing tube 2. After the temperature sensing tube 2 is inserted into the shell 1 and the arc-shaped clamping plate 3 contacts the temperature sensing tube 2, the arc-shaped strip 301 is clamped with the annular groove 201, which can limit the displacement of the temperature sensing tube 2 and improve the connection stability.

[0032] Both ends of the inner side of the driving ring 501 are provided with a thread groove 1 502 , and the housing 1 is provided with a thread groove 2 101 matched with the thread groove 1 502 . The cooperation between the thread groove 1 502 and the thread groove 2 101 allows the driving ring 501 to rotate and move on the housing 1 .

[0033] A second annular groove 503 is provided on the driving ring 501, and a plurality of sliders 504 are slidably connected in the second annular groove 503. The sliders 504 are slidably matched with the through holes provided on the shell 1, and one end of the slider 504 passes through the shell 1 and is connected and fixed to the wedge block 1 505. When the driving ring 501 is displaced, the second annular groove 503 drives the slider 504 to move, so that the slider 504 drives the wedge block 1 505 to slide and abut with the wedge block 2 506.

[0034] A thermal conductive sheet 601 is fixedly connected to the thermal conductive plate 6, and a thermal conductive sheet 302 is fixedly connected to one end of the arc-shaped clamping plate 3. The thermal conductive sheet 302 is in sliding contact with the thermal conductive plate 6 and the thermal conductive sheet 601. At the same time, the end of the temperature sensing tube 2 is in contact with the thermal conductive sheet 601, thereby achieving rapid heat conduction and shortening the temperature sensing judgment time.

[0035] During use, when the driving ring 501 rotates and moves toward the upper side of the shell 1, the annular groove 2 503 and the slider 504 cooperate to drive the wedge block 1 505 to move upward, and the wedge block 1 505 cancels the contact with the wedge block 2 506. The spring 4 drives the arc clamping plate 3 to approach the inner wall of the shell 1. Then the temperature sensing tube 2 can be inserted into the shell 1, and then the driving ring 501 is rotated in the opposite direction. The wedge block 1 505 descends and abuts against the wedge block 2 506, so that the arc clamping plate 3 is clamped and contacted with the temperature sensing tube 2, completing the quick installation.

[0036] Example 2

[0037] Reference Figure 4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a limiting ring 7 is slidably connected to the shell 1, and a plurality of limiting blocks 701 are fixedly connected to the limiting ring 7 in a ring shape with equal intervals, and a limiting groove 507 adapted to the limiting block 701 is opened on the driving ring 501.

[0038] In the above technical solution, after the driving ring 501 drives the arc-shaped clamping plate 3 to clamp the temperature sensing tube 2, the sliding limit ring 7 drives the limit block 701 to plug into the limit groove 507, which can limit the rotation of the driving ring 501, thereby improving the connection stability between the arc-shaped clamping plate 3 and the temperature sensing tube 2.

[0039] It can be understood that a sliding damping is provided between the limiting ring 7 and the housing 1 , so that the limiting ring 7 can stably hover when sliding to any position on the housing 1 .

[0040] The remaining structures are the same as those of Example 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
