Description

Technical Field

[0001] This utility model relates to the field of electronic water pump technology, and in particular, to an electronic water pump with an integrated thermostat. Background Technology

[0002] In automotive cooling systems and many industrial fluid circulation systems, water pumps and thermostats are two key components. Water pumps are responsible for circulating coolant or working fluid to dissipate heat from the engine or other equipment; thermostats regulate the flow path and flow rate of the fluid based on its temperature to maintain the system operating within a suitable temperature range.

[0003] However, traditional thermostats and water pumps are usually designed and installed separately. This separate structure has several drawbacks. On the one hand, the integration between the two is low, requiring complex piping connections to transfer the liquid between the water pump and the thermostat. This not only increases the difficulty and cost of system installation but may also lead to pressure loss and leakage risks during liquid transfer. On the other hand, the temperature sensing element of traditional thermostats often cannot directly sense the liquid temperature inside the casing. The temperature sensing element is usually located inside the thermostat's outer shell, with a certain spatial separation between it and the liquid. The liquid temperature needs to be transferred to the temperature sensing element through heat conduction, which results in a certain lag in temperature sensing. When the liquid temperature changes, the temperature sensing element cannot detect the temperature change in a timely and accurate manner, causing the thermostat to fail to adjust promptly. This affects the system's temperature control accuracy and response speed, and may consequently affect the performance and lifespan of the engine or related equipment. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an electronic water pump with an integrated thermostat.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An electronic water pump with an integrated thermostat includes: a pump casing with a rotating shaft installed inside, an impeller at the upper end of the rotating shaft; a volute fixedly installed on the upper end of the pump casing and forming a water passage cavity, the volute having an inlet, a first outlet, and a second outlet, all of which communicate with the water passage cavity; the flow area of ​​the first outlet being smaller than that of the second outlet; a first drain pipe connected to the first outlet; and a thermostat including a housing and a temperature sensing element, the housing having a drain cavity, a valve installed at one end of the drain cavity corresponding to the second outlet. The valve seat has a second drain pipe at one end and the flow area of ​​the first drain pipe is smaller than that of the second drain pipe. The temperature sensing element passes through the valve seat and is at least partially embedded in the water passage cavity. One end of the temperature sensing element has a push rod, and a valve plate is sleeved on the temperature sensing element. The temperature sensing element contains a temperature sensing medium. When the temperature of the temperature sensing medium exceeds a preset value, the temperature sensing medium will gradually expand as the temperature rises and push the push rod to extend outward, thereby causing the valve plate on the temperature sensing element to move away from the valve seat. A stop structure is fixed in the drain cavity and is used to abut against the outer end of the push rod.

[0007] Furthermore, the cover is connected to a spring frame, the spring frame is partially located inside the water passage cavity, and a compression spring is installed on the spring frame. One end of the compression spring abuts against the spring frame, and the other end abuts against the valve plate. The compression spring is used to apply a force toward the valve seat to the valve plate.

[0008] Furthermore, the spring frame includes an annular frame and a connecting plate. The annular frame is fixedly connected to the valve seat via the connecting plate. The annular frame is provided with a limiting groove, and one end of the compression spring is embedded in the limiting groove.

[0009] Furthermore, the temperature sensing element includes a housing, the housing includes a sleeve section, and the annular frame has a guide hole at its center for the sleeve section to pass through.

[0010] Furthermore, the outer shell also includes a pressing section, the cross-sectional profile of the sleeve section is smaller than that of the pressing section, the pressing section is connected to the sleeve section, and the pressing section has a pressing surface on the side facing the sleeve section. The valve plate is provided with a first annular cylinder and a second annular cylinder at its center. The diameter of the first annular cylinder is larger than that of the second annular cylinder. The first annular cylinder and the second annular cylinder are connected by an annular plate. The first annular cylinder surrounds the outer periphery of the pressing section, and the second annular cylinder is sleeved on the sleeve section. The pressing surface is in contact with the annular plate to transmit axial force.

[0011] Furthermore, the valve plate is provided with a positioning groove for the end of the compression spring to be embedded.

[0012] Furthermore, the pump housing is provided with a docking seat on its outer periphery, the docking seat is provided with a docking port, the docking port is provided with an opening for the plug to be inserted, and the docking port is provided with a pin.

[0013] Furthermore, the peripheral wall of the mating socket is provided with reinforcing ribs, and the side of the reinforcing rib corresponding to the opening of the mating socket is provided with a chamfer.

[0014] Furthermore, the abutment structure is an abutment bar, which is fixedly connected to the valve seat. The abutment bar has a groove facing the valve seat, and the push rod is embedded in the groove.

[0015] Furthermore, the edge of the second outlet is provided with a clamping mounting groove, and the edge of the valve seat is embedded in the clamping mounting groove and clamped and fixed by the volute and the cover.

[0016] This utility model has the following beneficial effects:

[0017] By organically integrating the thermostat with the volute, external connecting pipes are reduced, resulting in a more compact overall structure and lower installation difficulty and cost. This improves system reliability, reduces pressure loss and leakage risks during fluid transmission, and optimizes spatial layout. The temperature-sensing element is at least partially embedded in the water chamber, allowing direct contact with the liquid and thus direct and rapid sensing of temperature changes. When the liquid temperature exceeds a preset value, the sensing medium expands rapidly, altering the fluid flow in the drain chamber through the action of the push rod and valve plate. This direct temperature sensing and rapid adjustment mechanism effectively solves the problem of temperature sensing lag in traditional thermostats, improving the system's temperature control accuracy and response speed. This, in turn, better maintains the engine or related equipment within the appropriate temperature range, extending its service life and improving operational efficiency.

[0039] Please refer to Figures 1 to 7 An electronic water pump with an integrated thermostat in a preferred embodiment of the present invention includes a pump housing 100, a volute housing 200, and a thermostat 300.

[0040] A rotating shaft 110 is installed inside the pump casing 100, and an impeller 120 is provided at the upper end of the rotating shaft 110. A rotor is usually connected to the rotating shaft 110, and a stator surrounds the outer circumference of the rotor. The stator is energized to drive the rotor and the rotating shaft 110 to rotate through electromagnetic force. The rotation of the impeller 120 is used to drive the liquid to flow upward and be discharged from the outlet on the volute 200.

[0041] The volute 200 is fixedly installed on the upper end of the pump housing 100 and forms a water passage cavity 210. The volute 200 is provided with an inlet 211, a first outlet 212, and a second outlet 213, all of which are connected to the water passage cavity 210. The flow area of ​​the first outlet 212 is smaller than that of the second outlet 213. A first drain pipe 220 is connected to the first outlet 212. The upper end of the pump housing 100 is provided with a pump chamber, which is connected to the water passage cavity 210, thereby pumping the liquid in the water passage cavity 210 to be discharged from the first outlet 212 and / or the second outlet 213.

[0042] The thermostat 300 includes a housing 310 and a temperature sensing element 320. Specifically, the volute 200 and the housing 310 are connected and fixed by fasteners through corresponding holes. The housing 310 contains a drain chamber 311. A valve seat 312 is installed at one end of the drain chamber 311 corresponding to the second outlet 213, and a second drain pipe 350 is provided at the other end. The flow area of ​​the first drain pipe 220 is smaller than that of the second drain pipe 350. It can be understood that the valve seat 312 has a central hole for liquid to pass through, and the flow area of ​​the central hole is larger than that of the first outlet 212 and the first drain pipe 220. When the temperature is high and rapid liquid flow is required for heat dissipation, the liquid flows through the second outlet 213, valve seat 312, and second drain pipe 350, which have a larger flow area, to achieve high-flow-rate circulating cooling and improve the cooling effect. A temperature-sensing element 320 passes through the valve seat 312 and is at least partially embedded in the water passage cavity 210. One end of the temperature-sensing element 320 has a push rod 321, and a valve plate 340 is fitted onto the temperature-sensing element 320. The temperature-sensing element 320 contains a temperature-sensing medium. When the temperature of the temperature-sensing medium exceeds a preset value, the medium gradually expands as the temperature rises, pushing the push rod 321 outwards, thereby causing the valve plate 340 on the temperature-sensing element 320 to move away from the valve seat 312. A stop structure is fixed inside the drain cavity 311 and abuts against the outer end of the push rod 321, so that when the push rod 321 extends outwards, it pushes the temperature-sensing element 320 to move, thereby causing the valve plate to move. The temperature-sensing medium is typically paraffin wax, and the preset value is typically 70°C. When the temperature exceeds 70°C, the temperature-sensing medium gradually expands as the temperature rises, pushing the valve plate 340 open and gradually away from the valve seat 312, allowing the valve plate 340 to adjust its opening degree adaptively according to the temperature. The higher the temperature, the greater the expansion of the temperature-sensing medium, which will push the valve plate 340 to a greater distance from the valve seat 312, thereby regulating the flow rate of liquid entering the drain chamber 311 through the second outlet 213, so that more liquid can be discharged from the drain chamber 311 and the second drain pipe 350, improving the liquid circulation cooling efficiency. Of course, the temperature sensor will also feed back the high liquid temperature to the control system to control the rotation speed of the rotating shaft 110, thereby increasing the drainage volume.

[0043] This invention provides an electronic water pump with an integrated thermostat. By organically integrating the thermostat 300 with the volute 200, it reduces external connecting pipes, making the entire device more compact and lowering installation difficulty and cost. It improves system reliability, reduces pressure loss and leakage risk during liquid transmission, and optimizes space layout. The temperature sensing element 320 is at least partially embedded in the water cavity 210, allowing direct contact with the liquid and thus direct and rapid sensing of liquid temperature changes. When the liquid temperature exceeds a preset value, the temperature-sensing medium expands rapidly, and through the action of the push rod 321 and the valve plate 340, it promptly changes the flow of liquid in the drain cavity 311. This direct temperature sensing and rapid adjustment mechanism effectively solves the problem of lag in temperature sensing in traditional thermostats, improves the system's temperature control accuracy and response speed, and thus better maintains the engine or related equipment within a suitable temperature range, extending its service life and improving work efficiency. This invention's electronic water pump with an integrated thermostat significantly improves the timeliness and accuracy of temperature control while increasing integration, reducing installation costs, and optimizing space layout.

[0044] Reference Figure 2 and Figure 7 In some embodiments of this utility model, the cover 310 is connected to a spring frame, which is located within the water passage cavity 210. A compression spring 330 is mounted on the spring frame, with one end of the spring 330 abutting against the spring frame and the other end abutting against the valve plate 340. The compression spring 330 applies a force to the valve plate 340 toward the valve seat 312. In low-temperature operation, the elastic force of the compression spring 330 can stably press the valve plate 340 against the valve seat 312, ensuring the seal between the valve plate 340 and the valve seat 312, preventing liquid leakage from the drain cavity 311 before reaching the preset temperature, and improving the reliability of the system. When the temperature-sensing medium expands and pushes the push rod 321, the valve plate 340 can overcome the elastic force of the compression spring 330 and move, achieving precise regulation of the liquid flow.

[0045] Reference Figure 2 , Figure 7 and Figure 10In some embodiments of this utility model, the spring frame includes an annular frame 331 and a connecting plate 332. The annular frame 331 is fixedly connected to the valve seat 312 via the connecting plate 332. The annular frame 331 is provided with a limiting groove 333, and one end of the compression spring 330 is embedded in the limiting groove 333. The limiting groove 333 provides a stable installation position and limiting function for the compression spring 330, ensuring that the compression spring 330 can maintain a stable position and posture during operation, and avoiding inaccurate movement of the valve plate 340 due to the offset or shaking of the compression spring 330. Furthermore, the annular frame 331 is fixedly connected to the valve seat 312 via the connecting plate 332, allowing the compression spring 330 to transmit its force to the valve seat 312 through the annular frame 331 and the connecting plate 332. This results in a tighter fit between the valve seat 312 and the valve plate 340. In other words, the force at one end of the compression spring 330 acts on the valve plate 340, while the force at the other end is ultimately transmitted to the valve seat 312. Both forces push the valve seat 312 and the valve plate 340 closer together, thereby further ensuring the sealing performance when the valve seat 312 and the valve plate 340 are in contact.

[0046] Reference Figure 2 , Figure 7 and Figure 10 In a further embodiment of this utility model, the temperature sensing element 320 includes a housing 322, the housing 322 includes a sleeve section 323, and the annular frame 331 has a guide hole 334 at its center for the sleeve section 323 to pass through. The guide hole 334 provides precise guidance for the sleeve section 323, ensuring that the temperature sensing element 320 can move stably along a predetermined axial direction during movement, avoiding skewness or jamming, thereby ensuring the normal working performance and adjustment accuracy of the thermostat. By passing the sleeve section 323 through the guide hole 334, the connection between the temperature sensing element 320 and the spring frame is made tighter, further optimizing the internal structural layout of the thermostat, improving space utilization, making the overall structure of the thermostat more compact, which is beneficial to reducing the size and weight of the thermostat, and facilitating installation and use in limited spaces. It is understood that the housing 322 has a receiving space to receive the temperature sensing medium. The receiving space has a movable hole for the push rod 321 to move. The push rod 321 and the movable hole are sealed by a sealing structure (such as a sealing ring). Of course, in some embodiments, in order to avoid direct contact between the push rod 321 and the paraffin wax, the push rod 321 and the paraffin wax can be separated by rubber.

[0047] Reference Figure 2 , Figure 7 and Figure 10In a further embodiment of the present invention, the outer shell 322 further includes a pressing section 324. The cross-sectional profile of the sleeve section 323 is smaller than that of the pressing section 324. The pressing section 324 is connected to the sleeve section 323, and the pressing section 324 has a pressing surface 325 on the side facing the sleeve section 323. The valve plate 340 is provided with a first annular cylinder 341 and a second annular cylinder 342 at its center. The diameter of the first annular cylinder 341 is larger than that of the second annular cylinder 342. The first annular cylinder 341 and the second annular cylinder 342 are connected by an annular plate 343. The first annular cylinder 341 surrounds the outer periphery of the pressing section 324, and the second annular cylinder 342 is sleeved on the sleeve section 323. The pressing surface 325 is in contact with the annular plate 343 to transmit axial force. The contact between the pressing surface 325 and the annular plate 343 allows the temperature sensing element 320 to efficiently transmit axial force to the valve plate 340 during expansion, ensuring that the valve plate 340 can respond quickly and accurately to the action of the temperature sensing element 320. This enables rapid regulation of liquid flow and improves the regulation efficiency and response speed of the thermostat. The structure of the first annular cylinder 341, the second annular cylinder 342, and the annular plate 343 increases the contact area between the valve plate 340 and the temperature sensing element 320, further enhancing the sealing performance.

[0048] Reference Figure 2 , Figure 7 and Figure 10 In a further embodiment of this utility model, the valve plate 340 is provided with a positioning groove 344 for the end of the compression spring 330 to be inserted. The positioning groove 344 provides a precise installation position for the end of the compression spring 330, ensuring that the compression spring 330 can accurately abut against the valve plate 340, avoiding problems such as uneven force on the valve plate 340 or unsmooth movement caused by inaccurate positioning of the end of the compression spring 330. It also simplifies the assembly process between the compression spring 330 and the valve plate 340 and reduces the assembly difficulty.

[0049] Reference Figure 8 and Figure 9 In some embodiments of this utility model, a docking seat 130 is provided on the outer periphery of the pump housing 100. The docking seat 130 is provided with a docking socket 131, which has an opening for inserting a plug. A pin 132 is provided inside the docking socket 131. By inserting an external power plug into the docking socket 131, the electric water pump can be quickly connected to an external power supply or control system.

[0050] In a further embodiment of this utility model, a reinforcing rib 140 is provided on the peripheral wall of the mating socket 131, and the reinforcing rib 140 has a chamfer on the side corresponding to the opening of the mating socket 131. The provision of the reinforcing rib 140 can effectively enhance the structural strength of the side wall of the mating socket 131, enabling it to withstand greater external forces, avoiding damage to the mating socket 131 during plug insertion and removal, and extending the service life of the mating socket 130.

[0051] In a further embodiment of this utility model, the abutting structure is an abutting strip 400, which is fixedly connected to the valve seat 312. The abutting strip 400 is provided with a groove 410 facing the valve seat 312. The push rod 321 is embedded in the groove 410, thereby improving the stability of the cooperation between the push rod 321 and the abutting strip 400 and avoiding deviation during the pushing process of the push rod 321.

[0052] Reference Figure 2 and Figure 6 In a further embodiment of this utility model, the edge of the second outlet 213 is provided with a clamping mounting groove 214. The edge of the valve seat 312 is embedded in the clamping mounting groove 214 and clamped and fixed by the volute 200 and the cover 310. Thus, it is not necessary to use additional fasteners to fix the valve seat 312. The valve seat is installed and fixed by the connection and fixation of the volute 200 and the cover 310. The clamping mounting groove 214 also plays the role of positioning and installing the valve seat 312, ensuring the installation accuracy of the valve seat 312.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
