[0032] Please refer to Figures 1 to 3 FIG. 1 shows a part of a structure of a thermostat provided by an embodiment of the present application. As shown in the figure, the thermostat assembly includes a valve body 10 and a temperature sensing element 20.

[0033] The valve body 10 includes a valve seat 11, a valve core 12, and an elastic element 13. The valve seat 11 is connected to the valve core 12. The valve core 12 is internally provided with a first channel 121 and a second channel 122 that are connected in communication. The temperature sensing element 20 is connected to the valve core 12 by passing through the first channel 121.

[0034] The elastic member 13 is located in the second channel 122, and a first end of the elastic member 13 is connected with the valve seat 11, and a second end of the elastic member 13 is sleeved on the temperature sensing member 20 and abuts against the valve core 12.

[0035] The first channel 121 and the second channel 122 are coaxial, and the aperture of the second channel 122 is larger than the aperture of the first channel 121.

[0036] It should be understood that the elastic member 13 can be a spring structure, one end of the spring structure is connected with the valve seat 11, and the other end of the elastic member 13 is sleeved on the temperature sensing member 20 through the second channel 122 arranged at the first end of the valve core 12 and abuts against the valve core 12. In this way, when the spring is in a compressed state, the distance between the valve core 12 and the valve seat 11 is the smallest, and when the spring is in an extended state, the distance between the valve core 12 and the valve seat 11 is the largest.

[0037] It should be understood that one end of the temperature sensing member 20 abuts against the valve core 12 through the first channel 121 arranged at the valve core 12, and the other end of the temperature sensing member 20 is located outside the valve core 12. The temperature sensing member 20 can be a commonly used paraffin temperature sensing bag. In this way, when the temperature sensing member 20 detects that the temperature of the cooling liquid is greater than a specified value, the paraffin temperature sensing bag begins to melt and gradually becomes a liquid, the volume increases and presses the valve core 12, and the valve core 12 is pushed to move towards the bottom of the valve seat 11 to open the valve; and when the temperature sensing member 20 detects that the temperature of the cooling liquid is less than the specified value, the liquid paraffin temperature sensing bag gradually solidifies into a solid, the volume decreases, the compressed elastic member 13 acts on the valve core 12 with an upward thrust force, and the valve core 12 is pushed to move away from the valve seat 11 to close the valve.

[0038] In the embodiment of the application, the thermostat assembly includes a valve body 10 and a temperature sensing member 20; the valve body 10 includes a valve seat 11, a valve core 12 and an elastic member 13, the valve seat 11 is connected with the valve core 12, the valve core 12 is internally provided with a first channel 121 and a second channel 122 in communication, the temperature sensing member 20 passes through the first channel 121 and is connected with the valve core 12; the elastic member 13 is located in the second channel 122, and a first end of the elastic member 13 is connected with the valve seat 11, and a second end of the elastic member 13 is sleeved on the temperature sensing member 20 and abuts against the valve core 12; the first channel 121 and the second channel 122 are coaxial, and the aperture of the second channel 122 is larger than the aperture of the first channel 121. In this way, the channels with different apertures are arranged in the valve core 12, so that the temperature sensing member 20 is directly connected with the valve core 12, and the sealing performance of the thermostat can be improved.

[0039] Optionally, the valve core 12 further includes a third channel 123, which is connected to the first channel 121. The center line of the third channel 123 coincides with that of the first channel 121, and the diameter of the third channel 123 is larger than that of the first channel 121.

[0040] The temperature sensing element 20 passes through the third channel 123, the first channel 121 and the second channel 122 in sequence and is connected to the valve core 12.

[0041] It should be understood that the second channel 122, the first channel 121, and the third channel are sequentially arranged on the valve core 12 extending along the length of the valve core 12 from the direction toward the bottom of the valve seat 11, and the apertures of the second channel 122 and the third channel 123 are both larger than the aperture of the first channel 121. Specifically, the second channel 122 contains an elastic element 13, and the third channel 123 contains a portion of a temperature-sensing element 20 structure that is larger than the aperture of the first channel 121.

[0042] Thus, when the temperature sensing element 20 detects that the coolant temperature is higher than the specified value, the temperature sensing element 20 begins to increase in volume and presses against the valve core 12, thereby exerting an upward thrust on the valve core 12 and pushing it toward the bottom of the valve seat 11. At this time, the elastic element 13 is compressed. When the temperature sensing element 20 detects that the coolant temperature is lower than the specified value, the volume of the temperature sensing element 20 decreases accordingly. The compressed elastic element 13 exerts a downward counter-thrust on the valve core 12, thereby pushing the valve core 12 away from the valve seat 11.

[0043] Optionally, such as Figure 4 As shown, the thermostat assembly also includes a housing 30, which includes a receiving cavity with an opening at one end. A first snap-fit ​​member 111 is provided on the valve seat 11, and the valve seat 11 is disposed in the receiving cavity through the first snap-fit ​​member 111.

[0044] It should be understood that the first snap-fit ​​member 111 is disposed on the valve seat 11 at the end away from the valve core 12. Both the valve core 12 and the valve seat 11 are disposed in the receiving cavity and are connected to the housing 30 through the first snap-fit ​​member 111 on the valve seat 11.

[0045] Optionally, such as Figure 5 As shown, the first snap-fit ​​member 111 is a protruding structure surrounding the valve seat 11, and the opening of the accommodating cavity is provided with a boss structure that matches the protruding structure.

[0046] When the protruding structure coincides with the boss structure, the valve seat 11 is connected to the housing 30.

[0047] It should be understood that the first clamping member 111 is a protruding structure arranged around the valve seat 11 away from the valve core 12, when the valve seat 11 and the valve core 12 are located in the accommodating cavity, the valve seat 11 is rotated until the protruding structure on the valve seat 11 coincides with the boss structure at the opening of the accommodating cavity, at this time, the valve seat 11 is connected with the shell 30, and the thermostat assembly is assembled.

[0048] The protruding structure can include at least two small protrusions arranged around the valve seat 11, and the connection stability of the valve seat 11 and the shell 30 can be improved by rotating the valve seat 11 to increase the coinciding area of the small protrusions and the boss structure at the opening of the accommodating cavity.

[0049] Optionally, as shown in Figure 6 The bottom end of the temperature sensing member 20 is provided with a sliding rod 21, the shell 30 is provided with a first through hole 31, and the valve core 12 is slidably connected with the first through hole 31 through the sliding rod 21.

[0050] In the embodiment, the sliding rod 21 is slidably connected with the shell 30 by being arranged at the bottom end of the temperature sensing member 20, so that the valve core 12 abutting against the temperature sensing member 20 can also move along the length extension direction of the sliding rod 21 towards or away from the shell 30.

[0051] In specific implementation, when the temperature sensing member 20 detects that the temperature of the cooling liquid is greater than a specified value, the temperature sensing member 20 starts to increase in volume and press the valve core 12, and the valve core 12 is pushed to move towards the bottom of the valve seat 11 to open the valve, at this time, the elastic member 13 is compressed; when the temperature sensing member 20 detects that the temperature of the cooling liquid is less than a specified value, the temperature sensing member 20 decreases in volume, and the elastic member 13 which is compressed exerts a downward counterforce on the valve core 12 to push the valve core 12 to move away from the valve seat 11 to close the valve.

[0052] Optionally, as shown in Figure 7 The valve core 12 is connected with the valve seat 11 through the second clamping member 124.

[0053] It should be understood that the second clamping member 124 is arranged at the end of the valve core 12 facing the valve seat 11, and correspondingly, a connecting structure matched with the second clamping member 124 is arranged at the end of the valve seat 11 facing the valve core 12, and the valve core 12 is connected with the connecting structure through the second clamping member 124.

[0054] Optionally, the valve core 12 is slidably connected with the valve seat 11.

[0055] In the implementation, when the temperature of the coolant detected by the temperature sensing element 20 is greater than a predetermined value, the temperature sensing element 20 starts to increase in volume and press the valve core 12, and an upward thrust is applied to the valve core 12 to drive the valve core 12 to move towards the bottom of the valve seat 11, at this time, the elastic element 13 is compressed; when the temperature of the coolant detected by the temperature sensing element 20 is less than a predetermined value, the temperature sensing element 20 decreases in volume, and the elastic element 13, which is compressed, applies a downward counter-thrust to the valve core 12 to drive the valve core 12 to move away from the valve seat 11.

[0056] In an optional embodiment, the second clamping element 124 is an annular boss arranged around the valve core 12.

[0057] It should be understood that, in the case that the second clamping element 124 is an annular boss arranged around the valve core 12, an end of the valve seat 11 towards the valve core 12 is provided with a hook structure matched therewith, specifically, the valve seat 11 has a receiving structure, and the hook structure is arranged at the opening of the receiving structure, so that the annular boss can move along the receiving structure towards the bottom of the valve seat 11.

[0058] Optionally, the thermostat assembly further comprises a sealing element 40 arranged on the valve core 12.

[0059] The sealing element 40 is used to abut against the housing 30 when the valve is in a closed state.

[0060] In this embodiment, the sealing element 40 is arranged on the valve core 12 to improve the sealing performance of the thermostat assembly.

[0061] Optionally, the sealing element 40 comprises an annular sealing strip, and the annular sealing strip surrounds the third passage 123.

[0062] It should be understood that, by arranging the annular sealing strip around the third passage 123 on the valve core 12, the sealing performance of the valve core 12 and the housing 30 can be improved when the valve is in a closed state.

[0063] Optionally, the valve and the valve seat 11 are both made of injection molding material.
