Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, and in particular to a thermostat. Background Technology

[0002] The thermostat is a crucial automatic temperature regulating device in a car engine's cooling system. It automatically controls the coolant circulation path based on the engine's water temperature, ensuring the engine operates within a suitable temperature range, preventing both overcooling and overheating. Although small, the thermostat is the core of the engine's "temperature control system." By precisely regulating coolant circulation, it ensures the engine operates efficiently at its optimal temperature, reducing wear during cold starts and preventing damage from overheating. During routine maintenance, if abnormal water temperature is detected, the thermostat's condition should be checked promptly to avoid minor issues escalating into major problems.

[0003] Chinese Patent Publication No. CN218882342U discloses a thermostat, including a housing and a thermostat core. The housing has a first inlet, a first outlet, a second outlet, a first connecting channel, and a second connecting channel. The thermostat core has a first receiving cavity, a second receiving cavity, and a switching component. At least a portion of the switching component is movably disposed to connect or disconnect the first receiving cavity from the second receiving cavity. A first adjusting element is disposed in the first receiving cavity, and a second adjusting element is disposed in the second receiving cavity. When the first receiving cavity is disconnected from the second receiving cavity, at least a portion of the thermostat core switches between a first working position and a second working position under the thermal expansion and contraction of the first adjusting element. When the first receiving cavity is connected to the second receiving cavity, at least a portion of the thermostat core switches between the first working position and the second working position under the combined thermal expansion and contraction of the first and second adjusting elements. This invention solves the problem of high production costs of thermostats in the prior art.

[0004] For existing thermostats, in actual use, traditional thermostats are prone to leakage, which leads to failure to control cooling properly. In addition, the internal support structure of the thermostat is large, occupies a lot of space, and is heavy, which affects its use. Utility Model Content

[0005] The purpose of this invention is to provide a thermostat that solves the problem that existing thermostats are prone to leakage and cannot properly control cooling during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A thermostat includes a housing and a temperature sensor fixedly connected to the bottom of the housing. A hydraulic cylinder is fixedly connected to the top of the temperature sensor. A sealing groove is provided inside the housing, and a sealing disc is slidably connected inside the sealing groove. An anti-disengagement ring is provided on the top of the housing through an installation mechanism. A compression spring is elastically connected between the bottom of the anti-disengagement ring and the top of the sealing disc.

[0008] Preferably, a stabilizing cylinder is fixedly connected to the top of the sealing disc, and a compression spring is sleeved on the surface of the stabilizing cylinder.

[0009] Preferably, the top of the sealing disc and the bottom of the anti-detachment ring are both fixedly connected with several support feet, and one end of each support foot is fixedly connected with a U-shaped stabilizing block, which is in contact with the surface of the stabilizing cylinder.

[0010] Preferably, the center of the sealing disc is connected to the extrusion sleeve, and the output shaft of the hydraulic cylinder is located inside the extrusion sleeve.

[0011] Preferably, a protruding ring is fixedly connected to the bottom of the sealing groove, a receiving groove is opened at the bottom of the sealing disc, and a sealing gasket is fixedly connected to the bottom of the sealing disc.

[0012] Preferably, the mounting mechanism includes two locking blocks fixedly connected to the top of the housing, with an L-shaped locking buckle fixedly connected to the top of the locking blocks, an anti-disengagement ring located between the two locking buckles, and mounting blocks fixedly connected to the surface of the housing.

[0013] This utility model has the following beneficial effects:

[0014] When using the thermostat, the inside of the outer casing can be easily sealed by the contact between the sealing disc and the bottom of the sealing groove. During the sealing process, the pressure of the compression spring causes the sealing disc to apply pressure to the sealing groove. The sealing gasket increases the sealing performance, ensuring the airtightness of the inside of the outer casing. Cooling can be stopped by sealing when cooling is not required. When stabilizing the stabilizing cylinder is required, the supporting feet and the stabilizing fastener can support the stabilizing cylinder, thus ensuring the stable use of the sealing disc. While ensuring airtightness, it can save space and weight. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A thermostat includes a housing 1 and a temperature sensor 2 fixedly connected to the bottom of the housing 1. The housing 1 is a one-piece molded resin housing, which facilitates the protection and sealing of the internal structure. The temperature sensor 2 can detect the temperature of the automotive cooling system. A hydraulic cylinder 3 is fixedly connected to the top of the temperature sensor 2. The hydraulic cylinder 3 is existing technology. After activation, it can move the output shaft to squeeze the sealing disc 5, and it can also reset the sealing disc 5. A sealing groove 4 is opened inside the housing 1. The sealing disc 5 is slidably connected inside the sealing groove 4. During use, if cooling is not required, the sealing disc 5 can be lowered to fit against the bottom of the sealing groove 4, thereby sealing the interior of the housing 1. When cooling is required, the sealing disc 5 can be pushed open, allowing the interior of the housing 1 to be opened for cooling. The unit is equipped with an anti-detachment ring 7 via the mounting mechanism 6. The anti-detachment ring 7 can be fixed to the top of the housing 1 via the mounting mechanism 6. A compression spring 8 is elastically connected between the bottom of the anti-detachment ring 7 and the top of the sealing disc 5. When cooling is not required, the sealing disc 5 is in contact with the bottom of the sealing groove 4. At this time, the elastic force of the compression spring 8 will compress the sealing disc 5, so that the sealing disc 5 can better contact and seal with the sealing groove 4, preventing the interior of the housing 1 from being blocked for cooling. When the temperature is low, the temperature sensor 2 does not need to activate the hydraulic cylinder 3. When the temperature is high, the hydraulic cylinder 3 is activated to start cooling to reduce the problem. This facilitates the use of the car cooling system, ensures that the temperature is not too high, saves energy, and when not in use, the interior of the housing 1 can be sealed by the sealing disc 5, thereby ensuring the normal use of the cooling system.

[0024] Furthermore, a stabilizing cylinder 9 is fixedly connected to the top of the sealing disc 5, and a compression spring 8 is sleeved on the surface of the stabilizing cylinder 9. During the lifting and lowering process, the sealing disc 5 can be assisted by the stabilizing cylinder 9, and the compression spring 8 can be sleeved on the surface of the stabilizing cylinder 9, so that the compression spring 8 will not be misaligned, thus allowing the compression spring 8 to stably compress the sealing disc 5, ensuring the sealing performance, and facilitating the stability of the compression spring 8 when the sealing disc 5 moves repeatedly. After being compressed, the stabilizing cylinder 9 can move through the inside of the anti-detachment ring 7, preventing the anti-detachment ring 7 from affecting the movement of the stabilizing cylinder 9, so that the stabilizing cylinder 9 can be easily moved without obstruction.

[0025] Furthermore, several support feet 10 are fixedly connected to the top of the sealing disc 5 and the bottom of the anti-detachment ring 7. One end of each support foot 10 is fixedly connected to a U-shaped stabilizing block 11. The stabilizing block 11 is in contact with the surface of the stabilizing cylinder 9. During use, the support feet 10 can apply force to the stabilizing block 11, which can compress the stabilizing cylinder 9, thereby making the stabilizing cylinder 9 stable when moving. The support feet 10 and the stabilizing block 11 can reduce weight and installation space, making it convenient to use.

[0026] Furthermore, the center of the sealing disc 5 is connected to the extrusion sleeve 12, and the output shaft of the hydraulic cylinder 3 is located inside the extrusion sleeve 12. When the hydraulic cylinder 3 starts to extrude the sealing disc 5, the output shaft of the hydraulic cylinder 3 causes the sealing disc 5 to move by extruding the extrusion sleeve 12. This ensures that the hydraulic cylinder 3 will not be misaligned during the extrusion and movement of the sealing disc 5, ensuring that the sealing disc 5 can move vertically so that the stabilizing cylinder 9 can also move vertically, and preventing the extrusion spring 8 from tilting or becoming misaligned. This allows the sealing disc 5 to rise and fall vertically stably when it is extruded, ensuring its stability after use.

[0027] Furthermore, a protruding ring 13 is fixedly connected to the bottom of the sealing groove 4, and a receiving groove 14 is opened at the bottom of the sealing disc 5. A sealing gasket 15 is fixedly connected to the bottom of the sealing disc 5. When the sealing disc 5 is in contact with the bottom of the sealing groove 4 for sealing, the protruding ring 13 and the receiving groove 14 can be used to seal more easily, thereby improving the sealing effect. When the sealing disc 5 is subjected to the pressure of the compression spring 8, the sealing gasket 15 can be used to seal between the sealing disc 5 and the sealing groove 4, thereby better ensuring the sealing performance and enabling the sealing disc 5 to play its role better.

[0028] Furthermore, the mounting mechanism 6 includes two locking blocks 601 fixedly connected to the top of the housing 1. The top of the locking block 601 is fixedly connected to an L-shaped locking buckle 602. The anti-detachment ring 7 is located between the two locking buckles 602. The surface of the housing 1 is fixedly connected to a mounting block 603. When using the anti-detachment ring 7, the position of the anti-detachment ring 7 can be fixed by the locking buckles 602 on the two locking blocks 601, thereby facilitating the normal use of the anti-detachment ring 7. The mounting block 603 can easily move the housing 1, thereby making the housing 1 easy to take out and use and easy to fix the housing 1 inside the cooling equipment.

[0029] In summary:

[0030] When the car's cooling system is needed, a thermostat is required to control its operation. The thermostat prevents cooling when the temperature is within acceptable limits and allows cooling to occur when the temperature is high. The housing 1 is fixed inside the cooling system by the mounting block 603. During operation, a temperature sensor 2 detects a problem. When the temperature is high, the temperature sensor 2 activates the hydraulic cylinder 3, causing the output shaft of the hydraulic cylinder 3 to press against the compression sleeve 12 on the sealing disc 5, thereby moving the sealing disc 5. This movement of the sealing disc 5 allows the protruding ring 13 to leave the receiving groove. 14. The sealing gasket 15 leaves the bottom of the sealing groove 4, thus opening the interior of the outer shell 1 to facilitate cooling. During the movement of the sealing disc 5, the stabilizing cylinder 9 passes through the anti-detachment ring 7 to easily control the movement trajectory of the sealing disc 5, preventing misalignment during movement within the sealing groove 4 and ensuring the stability of the sealing disc 5. During the lifting and lowering of the sealing disc 5, the support feet 10 and stabilizing block 11 further enhance stability, ensuring the stability of the sealing disc 5's lifting and lowering while saving space. This prevents the sealing disc 5 from tilting and becoming unusable. The anti-detachment ring 7 is used during... The locking buckle 602 on the locking block 601 can be fixed to the top of the outer shell 1, thus ensuring the stability of the anti-detachment ring 7. This ensures high stability of the anti-detachment ring 7 during use and prevents it from detaching and affecting the sealing disc 5. After the sealing disc 5 is squeezed and moved away from the bottom of the sealing groove 4, the cooling device can cool normally. After the temperature drops and cooling is no longer needed, the temperature sensor 2 can close the hydraulic cylinder 3, and the output shaft on the hydraulic cylinder 3 can reset. After the hydraulic cylinder 3 resets, the compression spring 8 can apply pressure to the sealing disc 5, causing the sealing disc 5 to drop, allowing the protruding ring 13 to re-enter the container. Inside the groove 14, the sealing gasket 15 re-contacts the bottom surface of the sealing groove 4 to seal the inside of the outer casing 1, preventing further cooling until the temperature rises again. With the above structure, when using automotive cooling equipment, cooling can be stopped when the temperature is insufficient and started when the temperature is high. When cooling needs to be stopped, the sealing performance can be guaranteed, the inside of the outer casing 1 can be tightly sealed and leakage minimized, maintaining performance and stability. It can also improve the restriction and stability of the stabilizer 9 by the support foot 10 and the stabilizer block 11, and restrict and stabilize the stabilizer 9 while reducing weight and installation space.
