[0002] The main function of the electronic thermostat assembly is to automatically adjust the amount of water entering the radiator according to the cooling water temperature to ensure that the engine operates within the appropriate temperature range, thereby saving energy and protecting the engine.
[0003] The existing electronic thermostat assembly works passively, that is, when the engine temperature rises, the temperature-sensitive paraffin expands, compresses the hose, and then pushes the push rod to move. Driven by the push rod, the valve gradually opens, starting the large circulation, allowing the engine's large circulation loop cooling water to flow to the radiator, and the engine begins to dissipate heat. The amount of water flowing through the radiator can be automatically adjusted according to the change in water temperature.

A first inclined surface 12 is provided at the entrance of the infusion port 11. The outer wall of the guide sleeve 3 is provided with a liftable valve 5. The valve 5 is provided with a first inclined surface 12 corresponding to the second inclined surface 51. A first spring 6 is provided between the bracket 2 and the valve 5 and applies downward pressure to the valve 5 so that the first inclined surface 1 2 is pressed against the second inclined surface 51. The valve 5 is provided with a protective sleeve 52 and is sleeved on the outer wall of the guide sleeve 3. The end of the protective sleeve 52 is extended with a fitting portion 53 and shrinks inward to abut the body 1. The inner wall of the protective sleeve 52 is provided with an elastic contact portion 54 and abuts the guide sleeve 3. An O-ring 7 is provided between the valve 5 and the guide sleeve 3, and between the contact portion 54 and the guide sleeve 3. The first inclined surface 12 and the second inclined surface 51 are wide at the top and narrow at the bottom. As time goes by, the second inclined surface 51 of the valve 5 will have The first spring 6 applies a downward force to the valve 5, causing the valve 5 to gradually shrink toward the axial direction along the inclination direction of the second inclined surface 51, so that the first inclined surface 12 and the second inclined surface 51 are tightly against each other and fill the gap between the two, effectively improving the sealing performance, which is the first sealing measure; the fitting portion 53 is tightly fitted to the outer wall of the body 1 to prevent liquid from entering between the protective sleeve 52 and the guide sleeve 3, which is the second sealing measure; the contact portion 54 is tightly fitted to the outer wall of the guide sleeve 3, and cooperates with the O-ring 7 to further strengthen the sealing between the protective sleeve 52 and the guide sleeve 3, preventing water from leaking into between the valve 5 and the guide sleeve 3, which is the third sealing measure; an O-ring 7 is set between the valve 5 and the guide sleeve 3, which is the fourth sealing measure. Through the design of multiple sealing measures, the sealing performance is greatly improved to prevent water leakage. If one of the sealing measures fails due to aging, there are still multiple sealing measures to provide it with protection, thereby increasing the service life of the product.
[0027] It is worth mentioning that a safety cover 41 is provided at the end of the push rod 4. A second spring 42 is provided on the end surface of the safety cover 41 and the guide sleeve 3, and applies upward pressure to the safety cover 41. When the paraffin in the push rod 4 expands due to heat, the elastic force released by the second spring 42 exerts a greater pressure on the safety cover 41 and the liquid delivered to the infusion port 11 than the force exerted on the valve 5 by the first spring 6. At this time, the push rod 4 and the guide sleeve 3 make an upward movement, so that the valve 5 moves away from the infusion port 11, realizing a large circulation;
[0028] It is worth mentioning that a raised portion 13 is provided on both sides of the infusion port 11. The raised portion 13 is provided with a through groove 14 for accommodating the bracket 2.

One end of the supporting portion 15 is provided with a recessed groove 16 for supporting the guide sleeve 3 and the push rod 4. An O-ring 7 is provided between the recessed groove 16 and the guide sleeve 3. The outer wall of the supporting portion 15 is provided with an outwardly extending expansion portion 17, which abuts against the fitting portion 53. Here, the O-ring 7 strengthens the sealing between the guide sleeve 3 and prevents liquid from entering between the guide sleeve 3 and the push rod 4, thereby causing leakage. The expansion portion 17 causes the fitting portion 53 to expand outward, thereby causing the fitting portion 53 and the expansion portion 17 to abut against each other tightly, thereby playing the role of a first seal.
[0030] It is worth mentioning that the resistance portion 54 includes a support arm 541, the support arm 541 is extended with a curved portion 542, the curved portion 542 is extended with an action portion 543, and abuts against the outer wall of the guide sleeve 3, and the O-ring 7 is provided on the action portion 543. The force in the axial direction is applied to the action portion 543 through the curved portion 542, so that the action portion 543 is tightly fitted to the outer wall of the guide sleeve 3, and cooperates with the O-ring 7 to further enhance the sealing effect.
[0031] The above design scheme can make the product have the advantages of preventing water leakage, good sealing effect and prolonged service life.
[0032] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
