Description
Technical Field
[0001] The present invention relates to the technical field of filters, and particularly relates to an anti-clogging engine filter. Background Art
[0002] A filter refers to a fitting that filters impurities or gases through a filter paper. Generally, it refers to an automotive filter, which is a fitting of an engine. It is divided into different types according to different filtering functions: oil filter, fuel filter (gasoline filter, diesel filter, oil-water separator, hydraulic filter), air filter, air-conditioning filter, etc. An engine has three filters for air, oil, and fuel, generally called the "three filters", plus the air-conditioning filter, commonly known as the "four filters". They are respectively responsible for filtering in the lubrication system, the medium in the combustion system, the engine intake system, and the vehicle compartment air circulation system.
[0003] Currently, when an engine filter is in use, it mainly filters harmful impurities in the engine oil through a filter element inside the housing. However, during long-term use, due to the frequent filtration of the oil, the filter holes on the filter element are extremely prone to clogging. Its cleaning is rather inconvenient, and frequent disassembly and replacement not only take time and effort but also cost a lot, greatly affecting the service life of the filter. Therefore, it is necessary to design an anti-clogging engine filter to solve the above problems. Summary of the Invention
[0004] The purpose of the present invention is to provide an anti-clogging engine filter. By setting structures such as a filter hopper above the filter element, when the filter hopper filters the oil, the impurities intercepted on the filter hopper can slowly flow towards the annular storage cavity under the action of centrifugal force and their own gravity. And under the magnetic action of the magnetic ring, iron material impurities can be further adsorbed and constrained. At the same time, when the connecting rod drives the filter hopper to rotate, the connecting rod can also drive the scraper to scrape along the inner wall of the inner filter screen through a support member, so as to further scrape off the impurities filtered on the inner filter screen. The scraped impurities can accumulate in the groove and further constrain iron material impurities in cooperation with the magnetic block. Under the action of this structure, it can effectively avoid a large amount of impurities accumulating and clogging inside the filter in a short time, without the need for frequent disassembly and replacement, greatly improving the service life of the filter, so as to solve the above deficiencies in the technology.
[0005] To achieve the above purpose, the present invention provides the following technical solution: An anti-clogging engine filter, comprising:
[0006] A housing, the top of the housing is provided with an upper cover plate, and the bottom of the housing is provided with a lower cover plate. A plurality of oil inlet pipes are annularly and arrayedly arranged on the top side of the upper cover plate, and one end of the bottom side of the lower cover plate is provided with an oil outlet pipe;
[0007] The fixed seat is provided at the inner top end of the housing, and a connecting seat is connected to the bottom side of the fixed seat, and a filter element is provided between the connecting seat and the bottom side.

A scraper is connected between one ends of the multiple support members relative to the connecting rod, and the scraper abuts against the inner side of the inner filter screen.
[0012] Preferably, a groove is provided on the top side of the lower cover plate and inside the inner filter screen, and a magnetic block is provided on the inner bottom side of the groove.
[0013] Preferably, the support member includes a support cylinder fixedly connected to the side wall of the connecting rod. A spring is fixed at one end inside the support cylinder. One end of the spring is connected with a limit block, and a support rod is fixed at one end of the limit block relative to the spring. One end of the support rod extends outside the support cylinder and is fixedly connected with the scraper.
[0014] Preferably, an annular splash-proof plate is provided on the inner bottom side of the upper cover plate, and the bottom end of the oil inlet pipe is located inside the annular splash-proof plate.

[0018] In the above technical solution, the technical effects and advantages provided by the present invention:
[0019] By setting up structures such as a fixed seat, an annular storage cavity, a magnetic ring, a connecting rod, and a filter hopper above the filter element, the connecting rod can drive the filter hopper to rotate slowly. While the filter hopper filters the engine oil, the impurities intercepted on the filter hopper can slowly flow into the annular storage cavity under the action of centrifugal force and their own gravity.

[0020] By setting up a support member and a scraper inside the filter element, while the connecting rod drives the filter hopper to rotate, the connecting rod can also drive the scraper to scrape along the inner wall of the inner filter screen through the support member. Thus, the impurities filtered on the inner filter screen can be further scraped off. The scraped impurities can accumulate in the groove, and cooperate with the magnetic block to further constrain iron material impurities. Under the action of this structure, it can effectively avoid a large amount of impurities accumulating and blocking inside the filter in a short time, without the need for frequent disassembly and replacement, greatly improving the service life of the filter.
[0021] By setting up a support member composed of a support rod, a support cylinder, a spring and a limit block, the scraper can firmly press against the inner wall of the inner filter screen, so that the impurities on the inner wall of the inner filter screen can be better scraped off, greatly improving the use effect of the device.

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.
[0040] The present invention provides an anti-clogging engine filter as shown in Figures 1 - 10 and includes:
[0041] A housing 1, an upper cover plate 3 is provided at the top end of the housing 1, and a lower cover plate 5 is provided at the bottom end of the housing 1. A plurality of oil inlet pipes 7 are annularly arranged on the top side of the upper cover plate 3, and an oil outlet pipe 8 is provided at one end of the bottom side of the lower cover plate 5;
[0042] Both ends of the outer side of the housing 1 are symmetrically fixed with fixed disks 2. The bottom end of the upper cover plate 3 is fixed with a first connection disk 4, and the top end of the lower cover plate 5 is fixed with a second connection disk 6. The first connection disk 4 and the second connection disk 6 are both fixedly connected to the fixed disk 2 by bolts. Based on this, by providing the first connection disk 4, the second connection disk 6 and the fixed disk 2, it is convenient to disassemble and assemble the upper cover plate 3 and the lower cover plate 5 at both ends of the housing 1.
[0043] The fixed seat 9 is provided at the inner top end of the housing 1, and a connecting seat 19 is connected to the bottom side of the fixed seat 9. A filter element 18 is provided at the bottom side of the connecting seat 19.
[0044] The filter element 18 includes a filter paper layer 181. An outer filter screen 180 is provided on the outer side of the filter paper layer 181, and an inner filter screen 182 is provided on the inner side of the filter paper layer 181.
[0045] A driving motor 14 is fixedly connected to the top end of the housing 1. The output end of the driving motor 14 extends into the housing 1 and is provided with a connecting rod 12. A filter hopper 13 is fixedly provided above the connecting rod 12 near the top end. A retaining ring 15 is connected to the bottom side of the filter hopper 13. A sliding assembly is provided between the retaining ring 15 and the fixed seat 9.
[0046] An annular storage cavity 10 is formed on the top side edge of the fixed seat 9, and a magnetic ring 11 is provided on the inner bottom side of the annular storage cavity 10.
[0047] Engine oil can be introduced into the housing 1 through the oil inlet pipe 7, so that the oil can fall on the filter hopper 13. The oil can be filtered through the filter hopper 13, so that the clean oil passes through the fixed seat 9 and falls into the filter element 18, while the impurities are intercepted outside the filter hopper 13. By starting the driving motor 14, the driving motor 14 can drive the connecting rod 12 to rotate slowly, and then the connecting rod 12 drives the filter hopper 13 to rotate. Thus, under the action of centrifugal force and its own gravity, the impurities on the filter hopper 13 can slowly flow into the annular storage cavity 10, and under the magnetic action of the magnetic ring 11, the iron material impurities can be further adsorbed and restrained, so as to effectively prevent a large amount of impurities from entering the filter element 18 and causing blockage.
[0048] An annular splash-proof plate 22 is provided on the inner bottom side of the upper cover plate 3, and the bottom end of the oil inlet pipe 7 is located inside the annular splash-proof plate 22. By providing the annular splash-proof plate 22, it can prevent the oil flowing out of the oil inlet pipe 7 from directly splashing into the annular storage cavity 10.
[0049] The sliding assembly includes a plurality of sliding columns 16 provided on the bottom side of the retaining ring 15. A sliding groove 17 matching the sliding columns 16 is formed on the top side of the fixed seat 9. By driving the sliding columns 16 to slide in the sliding groove 17 by the retaining ring 15, the stability of the filter hopper 13 rotating on the fixed seat 9 can be greatly enhanced.
[0050] A protective cover 23 is provided outside the driving motor 14. Based on this, the driving motor 14 can be protected by the protective cover 23.
[0051] The bottom end of the connecting rod 12 extends into the filter element 18 and is symmetrically provided with multiple groups of support members 24. A scraping plate 27 is connected between one ends of the multiple support members 24 relative to the connecting rod 12. The scraping plate 27 abuts against the inner side of the inner filter screen 182.
[0052] On the top side of the lower cover plate 5 and inside the inner filter screen 182, there is a groove 20, and a magnetic block 21 is arranged on the inner bottom side of the groove 20.
[0053] When the engine oil enters the filter element 18 from the filter hopper 13, the engine oil can successively pass through the inner filter screen 182, the filter paper layer 181 and the outer filter screen 180, so as to filter the engine oil layer by layer again. Finally, the clean engine oil is discharged from the oil outlet pipe 8.
[0054] Moreover, when the connecting rod 12 drives the filter hopper 13 to rotate, the connecting rod 12 can also drive the support member 24 to rotate. Then, the support member 24 can drive the scraper 27 to rotate, so that the scraper 27 can scrape along the inner wall of the inner filter screen 182. Thus, the impurities filtered on the inner filter screen 182 can be further scraped off. The scraped impurities can accumulate in the groove 20, and the magnetic block 21 is used to further restrain the iron impurities. Under the action of this structure, it can effectively avoid the accumulation and blockage of a large amount of impurities inside the filter in a short time, and there is no need to disassemble and replace frequently, which greatly improves the service life of the filter.
[0055] The support member 24 includes a support cylinder 240 fixedly connected to the side wall of the connecting rod 12. One end inside the support cylinder 240 is fixed with a spring 25. One end of the spring 25 is connected with a limit block 26. The limit block 26 is fixedly provided with a support rod 241 relative to one end of the spring 25. One end of the support rod 241 extends outside the support cylinder 240 and is fixedly connected with the scraper 27.
[0056] The support rod 241 and the support cylinder 240 can form a support framework to be connected between the scraper 27 and the support rod 241. And with the cooperation of the spring 25 and the limit block 26, the scraper 27 can firmly press against the inner wall of the inner filter screen 182, so that the impurities on the inner wall of the inner filter screen 182 can be better scraped off, which greatly improves the use effect of the device.
[0057] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
