Description

Technical Field

[0001] This utility model relates to a stainless steel connector for an automotive engine oil level sensor. Background Technology

[0002] An engine oil level sensor is a device used to detect the oil level in a car engine. By monitoring changes in the oil level, it tracks oil consumption in real time and provides precise guidance for vehicle maintenance.

[0003] The connector is an important component of the fuel level sensor. It is not only an important part of the fuel system, but also connects the fuel gauge and fuel line to transmit fuel flow information.

[0004] Prolonged use can easily cause oil and gas to accumulate at the joint, leading to blockage and affecting the normal operation of the oil level sensor. Utility Model Content

[0005] The purpose of this utility model is to provide a technical solution for stainless steel connectors for automotive engine oil level sensors to address the shortcomings of existing technologies. This solution not only ensures smooth flow of engine oil within the connector but also reduces the risk of blockage caused by oil and gas accumulation, ensuring the normal operation of the oil level sensor and extending its service life.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] Stainless steel connector for automotive engine oil level sensor, including

[0008] The first and second connecting sections are integrally machined.

[0009] Its features are:

[0010] The first connecting section has an inlet hole and a through hole that are interconnected, and the second connecting section has a connecting hole and an outlet hole that are interconnected. The through hole is connected to the connecting hole. The inlet hole, the through hole, and the connecting hole are rotatably connected to an anti-clogging mechanism to remove impurities from the through hole. Through the design of the above structure, not only can the smooth flow of oil in the connector be guaranteed, but the risk of blockage caused by oil and gas accumulation can also be reduced, ensuring the normal operation of the oil level sensor and extending its service life.

[0011] Furthermore, the cleaning mechanism includes a first rotating part, a second rotating part, and helical blades. The first rotating part is connected to the second rotating part via a transmission rod, and the helical blades are distributed along the outer side of the transmission rod and located inside the guide hole. The first and second rotating parts are rotated by the engine oil, which in turn drives the helical blades to rotate synchronously via the transmission rod, thereby cleaning the guide hole, ensuring smooth flow of engine oil, and reducing the risk of blockage.

[0012] Furthermore, the first rotating part includes a first rotating ring, a first fixed disk, and a first fan blade. One end of the transmission rod is fixed to the center of the first fixed disk. The first rotating ring is connected to the first fixed disk through the uniformly distributed first fan blades. The inner wall of the liquid inlet is provided with a first annular groove. The first rotating ring rotates along the first annular groove. The first fan blade not only improves the connection strength and stability between the first rotating ring and the first fixed disk, but also increases the contact area with the engine oil. The flowing engine oil drives the first fan blade and the first fixed disk to rotate, which in turn drives the transmission rod and the helical blade to rotate synchronously. The first rotating ring improves the stability and reliability of the first rotating part when it rotates.

[0013] Furthermore, the second rotating part includes a second rotating ring, a second fixed disk, and a second fan blade. The other end of the transmission rod is fixed to the center of the second fixed disk. The second rotating ring is connected to the second fixed disk through the uniformly distributed second fan blades. The inner wall of the connecting hole is provided with a second annular groove. The second rotating ring rotates along the second annular groove. The second fan blade not only improves the connection strength and stability between the second rotating ring and the second fixed disk, but also increases the contact area with the engine oil. The flowing engine oil drives the second fan blade and the second fixed disk to rotate, which in turn drives the transmission rod and the helical blade to rotate synchronously. The second rotating ring improves the stability and reliability of the second rotating part when it rotates.

[0014] Furthermore, filter screens are provided between two adjacent first blades and the first rotating ring, and between two adjacent second blades and the second rotating ring. Through the design of the filter screens, not only can particulate impurities in the engine oil be filtered, but the risk of blockage of the guide hole can also be reduced.

[0015] Furthermore, the inner diameter of the inlet hole is larger than the inner diameter of the through hole, and the inlet hole transitions to the through hole through a tapered surface.

[0016] Furthermore, the inner diameter of the connecting hole is larger than the inner diameter of the through hole, and the connecting hole transitions to the through hole through a tapered surface.

[0017] Furthermore, the vertical cross-section of the liquid outlet gradually increases from the end near the connecting hole towards the outlet end.

[0018] Furthermore, a flange is provided on the side of the first connecting section near the second connecting section.

[0019] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0020] 1. This utility model can not only ensure the smooth flow of oil in the connector, but also reduce the risk of blockage caused by oil and gas accumulation, ensure the normal operation of the oil level sensor, and extend its service life.

[0021] 2. The first and second rotating parts are driven to rotate by the engine oil, which in turn drives the spiral blades to rotate synchronously through the transmission rod, thereby cleaning the guide hole, ensuring smooth flow of engine oil and reducing the risk of blockage.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0031] like Figures 1 to 4 As shown, the stainless steel connector for the automotive engine oil level sensor of this utility model includes a first connecting section 1 and a second connecting section 2 integrally formed; a flange 3 is provided on the side of the first connecting section 1 near the second connecting section 2 to facilitate assembly with pipelines.

[0032] The first connecting section 1 is provided with an inlet hole 4 and a through hole 5 that are interconnected. The inner diameter of the inlet hole 4 is larger than the inner diameter of the through hole 5. The inlet hole 4 transitions to the through hole 5 through a conical surface.

[0033] The second connecting section 2 is provided with a connecting hole 6 and a liquid outlet hole 7 that are interconnected. The through hole 5 is connected to the connecting hole 6. The inner diameter of the connecting hole 6 is larger than the inner diameter of the through hole 5. The connecting hole 6 transitions to the through hole 5 through a tapered surface.

[0034] The vertical cross-section of the liquid outlet 7 gradually increases from the end near the connecting hole 6 towards the outlet end.

[0035] An anti-clogging mechanism 8 is rotatably connected between the inlet hole 4, the through hole 5, and the connecting hole 6 to remove impurities from the through hole 5. The cleaning mechanism includes a first rotating part, a second rotating part, and a spiral blade 12. The first rotating part is connected to the second rotating part via a transmission rod 11. The spiral blade 12 is distributed along the outer side of the transmission rod 11 and is located inside the through hole 5. The first and second rotating parts are rotated by the engine oil, which in turn drives the spiral blade 12 to rotate synchronously via the transmission rod 11, thereby cleaning the through hole 5, ensuring smooth flow of engine oil, and reducing the risk of clogging.

[0036] The first rotating part includes a first rotating ring 13, a first fixed disk 14, and a first fan blade 15. One end of the transmission rod 11 is fixed to the center of the first fixed disk 14. The first rotating ring 13 is connected to the first fixed disk 14 through the uniformly distributed first fan blades 15. The inner wall of the liquid inlet 4 is provided with a first annular groove 9. The first rotating ring 13 rotates along the first annular groove 9. The first fan blade 15 not only improves the connection strength and stability between the first rotating ring 13 and the first fixed disk 14, but also increases the contact area with the engine oil. The flowing engine oil drives the first fan blade 15 and the first fixed disk 14 to rotate, which in turn drives the transmission rod 11 and the spiral blade 12 to rotate synchronously. The first rotating ring 13 improves the stability and reliability of the first rotating part when it rotates.

[0037] The second rotating part includes a second rotating ring 16, a second fixed disk 17, and a second fan blade 18. The other end of the transmission rod 11 is fixed to the center of the second fixed disk 17. The second rotating ring 16 is connected to the second fixed disk 17 through the annularly distributed second fan blades 18. The inner wall of the connecting hole 6 is provided with a second annular groove 10. The second rotating ring 16 rotates along the second annular groove 10. The second fan blade 18 not only improves the connection strength and stability between the second rotating ring 16 and the second fixed disk 17, but also increases the contact area with the engine oil. The flowing engine oil drives the second fan blade 18 and the second fixed disk 17 to rotate, which in turn drives the transmission rod 11 and the spiral blade 12 to rotate synchronously. The second rotating ring 16 improves the stability and reliability of the second rotating part during rotation.

[0038] The above structural design not only ensures smooth flow of oil within the connector, but also reduces the risk of blockage caused by oil and gas accumulation, ensuring the normal operation of the oil level sensor and extending its service life.

[0039] A filter screen is provided between two adjacent first blades 15 and the first rotating ring 13, and between two adjacent second blades 18 and the second rotating ring 16. Through the design of the filter screen, not only can particulate impurities in the oil be filtered, but the risk of blockage of the guide hole 5 can also be reduced.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to achieve essentially the same technical effect are all covered within the protection scope of this utility model.
