[0002] During the operation of the engine, metal debris, dust, carbon deposits oxidized at high temperatures, colloidal sediments, water, etc. are constantly mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids, keep the lubricating oil clean, and extend its service life. The oil filter is divided into full-flow type and split-flow type. The full-flow filter is connected in series between the oil pump and the main oil channel, so it can filter all the lubricating oil entering the main oil channel. The split-flow filter is connected in parallel with the main oil channel and only filters part of the lubricating oil sent by the oil pump.

[0003] Existing oil filters have insufficient filtering effects, resulting in the inability to effectively remove iron impurities in the oil, especially those iron filings that are tiny and difficult to remove through traditional filtering methods. These iron impurities will circulate in the oil, constantly causing wear and damage to the precision components inside the engine, thereby causing problems such as reduced engine performance and increased failure rates. In the long run, this will shorten the service life of the engine, increase the frequency of repairs and replacement of parts, increase maintenance costs, and may pollute the environment.

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] As attached Figure 1 To Attachment Figure 5 As shown: This embodiment provides an oil filter with a built-in magnetic attraction structure, including: a housing 1, and also including:

[0025] A magnetic attraction mechanism 2, which is arranged on the inner wall of the housing 1;

[0026] A filter mechanism 3, which is disposed in the inner cavity of the housing 1;

[0027] A pressure relief valve 4, which is arranged at the end of the filter mechanism 3;

[0028] The backflow suppression valve 5 is arranged at the connection between the housing 1 and the filter mechanism 3 .

[0029] Specifically, the magnetic attraction mechanism 2 includes a mounting ring 201 fixedly installed on the inner wall of the outer shell 1, a fixing groove 202 is opened on one side of the mounting ring 201, a fixing block 203 is inserted into the inner side of the fixing groove 202, a first fixing ring 204 is fixedly connected to one side of the fixing block 203, a magnetic strip 205 is fixedly installed on one side of the first fixing ring 204, one end of the magnetic strip 205 is fixedly connected to the second fixing ring 206, the number of magnetic strips 205 is several, and they are arranged in a circular array between the first fixing ring 204 and the second fixing ring 206.

[0030] In this embodiment: the outer shell 1 serves as the main structure of the filter, protects the internal components, and is connected to the engine and other components. Through the precise cooperation between the fixing groove 202 and the fixing block 203, the magnetic strip 205 can be firmly installed in a predetermined fixed position, thereby greatly enhancing the overall stability and reliability of the magnetic attraction mechanism 2. The magnetic attraction function of the magnetic strip 205 can effectively remove iron impurities such as iron filings in the engine oil, reduce the wear of these impurities on engine parts, thereby protecting the engine and extending its service life. The circular array layout of the magnetic strip 205 makes the magnetic field evenly distributed, which can more comprehensively absorb impurities in the engine oil.

[0031] Specifically, a threaded interface 101 is provided in the middle portion of one end of the outer shell 1, and the threaded interface 101 is connected to the clean oil outlet. A plurality of oil inlets 102 and mounting grooves 103 are provided on one side of the outer shell 1. The mounting grooves 103 are located on the outside of the oil inlets 102, and a rubber sealing ring 104 is sleeved inside the mounting grooves 103. A positioning spring 105 is provided at the end of the inner cavity of the outer shell 1. The backflow suppression valve 5 is made of an elastic rubber ring and is close to the end of the oil inlet 102.

[0032] In this embodiment: the threaded interface 101 is connected to the clean oil outlet to realize the outflow of the engine oil, the engine oil enters the filter through the oil inlet 102, and the filtering process begins. The installation groove 103 provides an installation position for the rubber sealing ring 104. The rubber sealing ring 104 ensures the sealing between the filter and the connecting parts. The positioning spring 105 provides support and positioning for the filtering mechanism 3 to ensure its stable operation. The backflow suppression valve 5 ensures that the engine oil flows in the correct direction, thereby improving the filtering efficiency of the filter. When the engine oil tries to flow in the opposite direction, the rubber ring is compressed and fits tightly to the oil inlet 102 to prevent the engine oil from flowing back.

[0033] Specifically, the filtering mechanism 3 includes a central tube 301 connected to the threaded interface 101, and filter element through holes are evenly distributed on the surface of the central tube 301. The outer side of the central tube 301 is sleeved with filter paper 302, and the filter paper 302 is fixed by metal clamps at both ends of the central tube 301. The central tube 301 is sleeved on the outer side of the positioning spring 105 through a slot at the end.

[0034] In this embodiment: there is a filter through hole on the surface of the central tube 301, allowing the engine oil to pass through. The filter paper 302 is fixed by the metal clamps at both ends of the central tube 301 and wrapped around the outside of the central tube 301. When the engine oil passes through the filter paper 302, the solid particles and impurities therein are intercepted, thereby ensuring the purity of the engine oil.

[0035] Specifically, the pressure relief valve 4 includes a mounting column 401 fixedly mounted on the inner end of the central tube 301. The mounting column 401 is a hollow structure, and a side hole 402 is provided on the side of the mounting column 401. A buffer spring 403 is fixedly mounted on the inner cavity of the mounting column 401, and a valve 404 is fixedly connected to the end of the buffer spring 403.

[0036] In this embodiment: when the internal pressure of the filter is too high, the pressure relief valve 4 automatically opens to release the pressure to prevent the filter from being damaged. The mounting column 401 is a hollow structure for mounting and supporting other components. The side hole 402 is a channel for the oil to flow out. The buffer spring 403 is used to control the opening and closing of the valve 404.

[0037] The working principle and use process of this utility model:

[0038] The engine oil enters the filter through the oil inlet 102, and the iron impurities in the engine oil are adsorbed by the magnetic strip 205 in the magnetic attraction mechanism 2. Then, the engine oil passes through the filter paper 302, and the solid particles and impurities therein are intercepted. The filtered engine oil flows out through the filter element through holes and the threaded interface 101 on the surface of the central tube 301 and enters the engine or other systems. When the internal pressure of the filter is too high, the valve 404 is pushed open, the buffer spring 403 is compressed, and the engine oil flows out through the side hole 402. The backflow suppression valve 5 is made of an elastic rubber ring to ensure that the engine oil flows in the correct direction and prevent backflow. When the engine oil tries to flow in the opposite direction, the rubber ring is compressed and fits tightly to the oil inlet 102 to prevent the engine oil from flowing back.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
