[0001] The utility model relates to the technical field of filters, in particular to a wear-resistant automobile engine oil filter. Background Technique

[0002] During the operation of an automobile engine, engine oil plays a crucial role in lubrication, cooling, cleaning, etc. However, with the continuous operation of the engine, various impurities will be mixed into the engine oil, such as metal particles, dust, combustion residues, etc. If these impurities cannot be effectively filtered out, it will cause serious wear to the engine, reducing the performance and service life of the engine.

[0003] Traditional automobile engine oil filters have certain limitations in terms of filtration performance and wear resistance. On the one hand, their filtration accuracy may not be high enough to completely remove tiny impurity particles; on the other hand, after long-term use, the components of the filter may wear, resulting in a decline in sealing performance, a reduction in filtration effect, and even problems such as engine oil leakage.

[0004] To solve these problems, this wear-resistant automobile engine oil filter came into being. Through unique structural design and material selection, it aims to improve filtration accuracy, enhance wear resistance, ensure that the engine can always receive clean engine oil supply, thus maintaining a good operating state and extending the service life of the engine.

A filter element 7 is installed between the inlet housing 3 and the strengthening safety valve 6;

[0028] I. Housing 1

[0029] Structural features: The top is a polygonal top 2, which facilitates installation and disassembly operations. It is provided with external threads for easy connection and fixation to corresponding components of the automotive engine. The material is high-strength alloy, having good corrosion resistance and wear resistance.

[0030] Function: Provide external protection and an installation foundation for the entire filter.

[0031] II. Inlet Housing 3

[0032] Structural features: It is provided with a connection hole 5, and the surface is provided with a corrosion-resistant coating. There is an outlet inside, which communicates with the middle of the filter element 7.

[0033] Function: Guide the engine oil into the filter and transport the engine oil to the filter element 7 for filtration.

[0034] III. Sealing Ring 4

[0035] Structural features: Installed on the side of the housing 1.

[0036] Function: Ensure the sealing performance at the connection part between the housing 1 and the engine, and prevent engine oil leakage.

[0037] IV. Strengthening Safety Valve 6

[0038] Structural features: The mounting plate 61 is fixedly connected to the outer shell 1. One end of the mounting plate 61 is fixedly connected to a sleeve 62. A rod 63 is slidably sleeved inside the sleeve 62. A spring 64 is sleeved on the sleeve 62 and the rod 63. One end of the spring 64 is fixedly connected to a sealing plate 65.

[0039] Function: It plays a safety protection role when the engine oil pressure is abnormal, preventing excessive pressure from damaging the engine.

[0040] V. Filter element 7

[0041] Structural features: The shape can be grid-like or honeycomb-like.

[0042] Function: Filter impurities in the engine oil to ensure clean engine oil enters the engine.

[0043] Working principle:

[0044] When the vehicle engine is running, the engine oil enters the filter through the connection hole 5 on the feed housing 3 under the action of pressure.

[0045] Feed housing 3: Guides the engine oil into the interior of the filter and transports the engine oil to the middle of the filter element 7 through the discharge port inside it.

[0046] Filter element 7: Whether it is grid-like or honeycomb-like, its main function is to filter impurities in the engine oil. When the engine oil passes through the filter element 7, the impurities therein are intercepted, and the clean engine oil continues to flow.

[0047] During the whole process, if the engine oil pressure rises abnormally, the enhanced safety valve 6 starts to function.

[0048] Enhanced safety valve 6: When the engine oil pressure is too high, the pressure pushes the sealing plate 65, causing the rod 63 to slide inside the sleeve 62 and compress the spring 64. At this time, part of the engine oil can flow out through the safety valve, thereby reducing the pressure inside the filter and preventing excessive pressure from damaging the engine. When the pressure returns to normal, the spring 64 pushes the sealing plate 65 back to its original position to close the safety valve again.

[0049] Outer shell 1: Provides a stable external structure for the operation of the entire filter. Its high-strength alloy material ensures stability and corrosion resistance under various working conditions. At the same time, the sealing ring 4 on the side of the outer shell 1 ensures the sealing performance of the connection part between the filter and the engine, preventing engine oil leakage.

[0050] As Figure 1 shown, in some embodiments, the outer shell 1 is provided with external threads, and the sealing ring 4 is installed on the side of the outer shell 1; it is convenient for installation and disassembly: The design of the external threads enables the filter to be easily installed on the engine by rotation and can also be conveniently disassembled when the filter needs to be replaced.

[0051] Ensure a firm connection: Threaded connections can provide a strong connection force to ensure that the filter does not loosen or fall off during the operation of the engine.

[0052] As Figure 2 shown, in some embodiments, the sealing plate 65 is adapted to the middle diameter of the filter element 7; when the engine oil is filtered through the filter element 7, the tight fit between the sealing plate 65 and the filter element 7 can prevent the unfiltered engine oil from leaking from the edge of the filter element 7, ensuring that all the engine oil must pass through the filtration of the filter element 7 before continuing to flow.

[0053] As Figure 2 shown, in some embodiments, the shape of the filter element 7 is grid-shaped; the grid-shaped filter element 7 is usually composed of a series of parallel strip or sheet structures, and certain gaps and channels are formed between these structures.

[0054] The material may be filter paper, fiber material or other materials with filtering performance.

[0055] As Figure 3 shown, in some embodiments, the shape of the filter element 7 is honeycomb-shaped; the honeycomb structure provides a large number of filtering channels. When the engine oil passes through these channels, impurities are effectively intercepted inside the filter element 7. Since the unit structure of the honeycomb is relatively regular, the engine oil can pass through each channel evenly, improving the uniformity and effect of filtration.

[0056] As Figure 2 shown, in some embodiments, there is a discharge port in the feed housing 3, which is connected to the middle part of the filter element 7; by connecting the discharge port to the middle part of the filter element 7, the engine oil can enter the filter element 7 more evenly for filtration. This can avoid the engine oil concentrating on one side or a certain part of the filter element 7, improving the uniformity and efficiency of filtration.

[0057] As Figure 1 shown, in some embodiments, the material of the outer shell 1 is high-strength alloy, which has good corrosion resistance and wear resistance; during the installation, disassembly and use process, the filter outer shell 1 may rub against other components. Good wear resistance can reduce the wear of the outer shell 1, maintain its appearance and dimensional accuracy, and ensure the normal installation and sealing performance of the filter.

[0058] As Figure 2 shown, in some embodiments, the surface of the feed housing 3 is provided with a corrosion-resistant coating to improve its service life; the engine oil may contain some corrosive substances, and long-term contact will cause corrosion to the feed housing 3. The corrosion-resistant coating can effectively isolate the direct contact between the engine oil and the feed housing 3, prevent the occurrence of corrosion, and thus extend the service life of the feed housing 3.

[0059] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
