Description

Technical Field

[0001] The utility model belongs to the technical field of engines, and particularly relates to a thermostat with an exhaust structure. Background Art

[0002] A thermostat is an automatic temperature control device. The main function of the thermostat is to control the circulation path of the engine coolant to ensure that the engine operates at an appropriate temperature. Specifically, the thermostat changes the circulation range of the coolant by adjusting the amount of water entering the radiator, thereby adjusting the heat dissipation capacity of the cooling system. When the engine is cold-started, the thermostat closes, and the coolant circulates in a small loop inside the engine, which helps the engine warm up quickly; when the engine reaches the normal operating temperature, the thermostat opens, and the coolant begins to flow through the radiator for a large loop to effectively dissipate heat and prevent the engine from overheating. Since there may be gas in the pipeline coolant, the gas will affect the flow of the coolant, thereby affecting the efficiency of the thermostat in cooling the engine and causing the engine to overheat. Therefore, an exhaust structure is provided on the thermostat.

[0003] However, when installing the existing exhaust structure, additional parts need to be added, resulting in troublesome installation and insufficient stability. After being used for a long time, it is prone to position deviation, causing the thermostat to leak water and affecting the cooling effect of the thermostat on the engine.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further described in subsequent drawings.

[0041] Next, the present utility model will be further described in detail with specific embodiments in conjunction with the accompanying drawings. See Figures 1-6 :

[0042] Embodiment 1.

[0043] This embodiment provides a thermostat with an exhaust structure, including:

[0044] Upper frame 1;

[0045] Lower frame 2, the upper frame 1 is connected to the lower frame 2;

[0046] Exhaust mechanism 3, the exhaust mechanism 3 includes a first air pipe 31, a second air pipe 32 and a float 33. The first air pipe 31 is arranged at the bottom of the upper frame 1. An exhaust hole 34 is provided at the top of the upper frame 1, and the exhaust hole 34 is communicated with the first air pipe 31. The second air pipe 32 is arranged above the lower frame 2. The first air pipe 31 is sleeved outside the second air pipe 32. The float 33 is arranged in the first air pipe 31;

[0047] Control mechanism 4, arranged between the upper frame 1 and the lower frame 2;

[0048] Fixing mechanism, arranged on the upper frame 1, and the fixing mechanism is used to fix the lower frame 2 and the control mechanism 4;

[0049] Wherein, the inner diameter of the exhaust hole 34 is smaller than the diameter of the float 33. Rubber gaskets 37 are provided at the top of the second air pipe 32 and the bottom of the exhaust hole 34. The control mechanism 4 is used to control the flow direction of the liquid in the thermostat.

[0050] As Figures 1-6 shown, the first air pipe 31 and the upper frame 1 are integrally designed, the second air pipe 32 and the lower frame 2 are integrally designed. The first air pipe 31 is sleeved outside the second air pipe 32. The inner wall of the first air pipe 31 contacts the outer wall of the second air pipe 32. A float 33 is arranged in the first air pipe 31. The float 33 can move freely in the first air pipe 31. When the coolant flows in the thermostat, the gas in the coolant can enter the first air pipe 31 through the bottom of the second air pipe 32 and finally be discharged through the exhaust hole 34. When the gas in the coolant is discharged, the coolant will enter and fill the first air pipe 31 and the second air pipe 32. At this time, the float 33 floats under the buoyancy force and blocks the exhaust hole 34, preventing the coolant from flowing out through the exhaust hole 34. It can exhaust smoothly and prevent coolant leakage, thereby improving the cooling efficiency of the thermostat. The first air pipe 31 and the second air pipe 32 are sleeved, and the coolant in the thermostat can be effectively exhausted without adding extra parts. At the same time, the installation is simple and the maintenance efficiency is improved.

[0051] The first exhaust pipe is arranged on the upper frame 1, the second exhaust pipe is arranged on the lower frame 2. The first exhaust pipe and the second exhaust pipe are sleeved and fixed, which improves the stability of the exhaust structure. At the same time, the fixing mechanism can fix the lower frame 2 to prevent the lower frame 2 from shaking during operation and affecting the stability of the exhaust mechanism 3.

[0052] When installing the thermostat, it is only necessary to install the control mechanism 4 between the upper frame 1 and the lower frame 2, then align and connect the first air pipe 31 and the second air pipe 32, and finally fix the second frame and the control mechanism 4 with the fixing mechanism. Without adding any additional parts, the coolant flowing through the thermostat can be exhausted, and it is convenient for installation and disassembly, which can effectively improve the efficiency of disassembly and maintenance.

[0053] There is a small circulation port at the bottom of the lower frame 2 and a large circulation port at the top of the upper frame 1. The control mechanism 4 is used to control the flow direction of the coolant passing through the thermostat. At low temperatures, the control mechanism 4 is closed, and the coolant flows out from the small circulation port at the bottom of the lower frame 2. At this time, the cooling efficiency of the coolant is low, which is convenient for the engine to warm up and start. When the engine is started, the temperature rises. At this time, the control mechanism 4 is opened, and the coolant can flow out from the top of the upper frame 1 into the large circulation port. At this time, the cooling capacity of the coolant increases, and the cooling efficiency of the thermostat on the engine is improved, which can effectively cool the engine.

[0054] Rubber gaskets 37 are provided at the top of the second air pipe 32 and the bottom of the exhaust hole 34. The rubber gasket 37 can contact the surface of the float 33 when the float 33 descends and rises, thereby improving the sealing performance of the float 33 and preventing leakage of coolant during the exhaust process. At the same time, the rubber gasket 37 can also protect the float 33 and the first air pipe 31, reducing the wear between the float 33 and the inner wall of the pipe during the rising and falling process, thereby extending the service life of the exhaust structure.

[0055] The upper frame 1 and the lower frame 2 are both made of stainless steel. Stainless steel has high strength and strong corrosion resistance, which can ensure the strength and stability of the thermostat and exhaust structure, and at the same time has a long service life.

[0056] Float 33 can be made of materials such as copper, but stainless steel is preferred in this invention. Stainless steel has strong resistance to high temperatures and corrosion, and can maintain stability and reliability in various harsh environments. Stainless steel also gives float 33 a high opening and closing force, thereby providing high exhaust capacity and effectively improving the exhaust effect of the exhaust structure.

[0057] Example 2:

[0058] This embodiment provides a thermostat with an exhaust structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] A fixing column 36 is provided below the second air pipe 32 . One end of the fixing column 36 is connected to the lower frame 2 , and the other end is connected to the bottom of the second air pipe 32 . An air inlet 35 is provided at the bottom of the second air pipe 32 .

[0060] like Figures 1-3As shown in FIGS. 6, the fixed column 36 and the second air pipe 32 are integrally designed. An air inlet hole 35 is provided at the bottom of the second air pipe 32 and the fixed column 36. The fixed column 36 is connected to the lower frame 2. The fixed column 36 can fix the first air pipe 31 and the second air pipe 32, improving the stability of the exhaust mechanism 3. The air inlet hole 35 is located above the lower frame 2. The coolant enters the thermostat between the upper frame 1 and the lower frame 2 and flows out of the thermostat above the upper frame 1 or below the lower frame 2. The fixed column 36 can guide the coolant, increasing the probability of the gas in the coolant entering the air inlet hole 35, thereby improving the exhaust efficiency of the exhaust mechanism 3.

[0061] A contact groove 38 is provided at the top of the second air pipe 32. The surface of the floating ball 33 contacts the inner wall of the contact groove 38.

[0062] As Figures 2-3 shown, the contact groove 38 is semi-circular. The contact groove 38 can keep the floating ball 33 in a relatively stable position inside the first air pipe 31 when there is no exhaust. Especially when the exhaust structure is opened, it can prevent the floating ball 33 from shaking excessively or deviating from the normal position due to the fluctuations of water flow or air flow.

[0063] At the same time, it can also reduce the wear between the floating ball 33 and the top of the second air pipe 32 after the floating ball 33 drops, effectively extending the service life of the exhaust structure.

[0064] A rubber gasket 37 provided at the top of the second air pipe 32 fits the inner wall of the contact groove 38.

[0065] The control mechanism 4 includes:

[0066] An upper valve 41, which is arranged inside the upper frame 1 and abuts against the bottom of the upper frame 1;

[0067] A blocking arm 42, which is arranged at the top of the upper frame 1;

[0068] A temperature-sensing push rod 43, one end of the temperature-sensing push rod 43 penetrates the upper valve 41 and is connected to the blocking arm 42;

[0069] A first spring 44, which is arranged between the upper valve 41 and the lower frame 2. One end of the first spring 44 abuts against the upper valve 41, and the other end abuts against the lower frame 2.

[0070] As Figures 1-4As shown in the figure, the upper valve 41 is used to block the coolant from flowing into the large circulation port. The blocking arm 42 is arranged at the top of the upper frame 1. The blocking arm 42 and the upper frame 1 are integrally designed. One end of the blocking arm 42 facing the upper frame 1 is provided with a contact groove. The upper valve 41 is sleeved on the temperature-sensing push rod 43 and fixed to the temperature-sensing push rod 43. Paraffin is provided inside the temperature-sensing push rod 43. One end of the temperature-sensing push rod 43 is inserted into the contact groove and abuts against the blocking arm 42, and the other end passes through the lower frame 2 and is slidably connected to the lower frame 2. The first spring 44 is arranged between the lower frame 2 and the upper frame 1.

[0071] When the temperature rises, the paraffin expands due to heat. The temperature-sensing push rod 43 upwardly abuts against the blocking arm 42, and the blocking arm 42 exerts a downward force on the temperature-sensing push rod 43, causing the temperature-sensing push rod 43 to drive the upper valve 41 to move downward, thereby opening the large circulation port, enabling the coolant to flow out from the large circulation port, and dissipating heat from the engine. The first spring 44 can reset the temperature-sensing push rod 43 and the upper valve 41 after the coolant temperature decreases.

[0072] A lower valve is further provided at one end of the temperature-sensing push rod 43 passing through the lower frame 2. The lower valve is sleeved on the temperature-sensing push rod 43 and fixed. A second spring is provided between the lower valve and the lower frame 2. The lower valve can control the opening and closing of the small circulation port. When the temperature reaches the maximum temperature, the temperature-sensing push rod 43 moves downward, driving the upper valve 41 and the lower valve to move downward. At this time, the lower valve blocks the small circulation port, and all the coolant flows into the large circulation port, thereby enhancing the heat dissipation effect of the thermostat on the engine and maintaining the normal operation of the engine.

[0073] Embodiment 3:

[0074] This embodiment provides a thermostat with an exhaust structure. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

The bottom of the first fixing groove 21 is in contact with the bottom of the second fixing groove 12.

[0077] Such as Figure 1 、 4As shown in FIG. -6, the fixed arm 11 and the upper frame 1 are integrally designed. Multiple fixed arms 11 are provided to fix the lower frame 2. The fixed arm 11 is clamped in the first fixing groove 21, which can prevent the horizontal shaking when the lower frame 2 is fixed to the upper frame 1. The second fixing groove 12 is provided on the fixed arm 11, and the bottom of the second fixing groove 12 contacts the bottom of the first fixing groove 21. The first fixing groove 21 and the second fixing groove 12 are engaged with each other, which can prevent the up-and-down shaking when the lower frame 2 is fixed to the upper frame 1, thereby improving the connection stability between the upper frame 1 and the lower frame 2. At the same time, it is convenient for installation and disassembly, and improves the installation efficiency.

[0078] The fixing mechanism further includes:

[0079] A plurality of fixing protrusions 22, which are radially arranged on the lower frame 2. One end of the first spring 44 abuts against the upper valve 41, and the other end abuts against the fixing protrusion 22;

[0080] A stabilizing ring 23, which is arranged on the lower frame 2. The outer periphery of the stabilizing ring 23 is connected to the fixing protrusion 22, and the outer wall of the temperature sensing push rod 43 is slidably connected to the inner wall of the stabilizing ring 23.

[0081] As Figures 1-2 shown in FIGS. 4 and 6, the fixing protrusion 22 and the lower frame 2 are integrally designed. A plurality of fixing protrusions 22 are radially arranged on the lower frame 2, which can provide a stable abutting force for the first spring 44 when the temperature sensing push rod 43 controls the descent of the upper valve 41. The stabilizing ring 23 is provided on the fixing protrusion 22, and the stabilizing ring 23 is slidably connected to the temperature sensing push rod 43. The stabilizing ring 23 can play a limiting role on the temperature sensing push rod 43 to prevent the temperature sensing push rod 43 from shifting during operation, and improve the working stability of the thermostat.

[0082] One end of the second spring abuts against the top of the lower valve, and the other end abuts against the bottom of the fixing protrusion 22.

[0084] A first sealing ring 45, which is arranged between the upper valve 41 and the upper frame 1;

[0085] A second sealing ring 46, which is arranged outside the upper frame 1.

[0086] As Figures 1-4 shown, the first sealing ring 45 is used to seal the large circulation port, preventing the coolant from flowing into the large circulation port when the upper valve 41 is closed, which can enable the engine to quickly rise to the working temperature and improve the working efficiency of the engine.

[0087] The second sealing ring 46 is used to seal the upper frame 1, preventing the coolant from flowing into the large circulation port through the gap at the edge of the upper frame 1 when the upper valve 41 is closed, which affects the working efficiency of the engine.

[0088] The above embodiments are only preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
