Description

Technical Field

[0001] This utility model relates to the field of oil filters, and more specifically, it relates to a long-life spin-on oil filter. Background Technology

[0002] Mechanical equipment is very common in people's work, life, and industrial production. Friction often occurs between the moving parts of mechanical equipment. To reduce frictional resistance and reduce wear on parts, engine oil needs to be continuously delivered to the friction surfaces of each moving part to form a lubricating film for lubrication. Since engine oil itself contains a certain amount of colloids, impurities, water, and additives, and during engine operation, the introduction of metal shavings, the entry of airborne debris, and the generation of engine oil oxides gradually increase the amount of impurities in the engine oil. Therefore, an oil filter is needed to remove impurities from the engine oil. Existing oil filters often use rolled filter paper to absorb impurities in the engine oil and clean it. However, after long-term use, a large amount of impurities will adhere to the surface of the filter paper, thus hindering the flow of engine oil and causing the oil filter to reach the end of its service life and need to be replaced. Therefore, the service life of existing oil filters is limited and cannot be extended. At the same time, existing oil filters only use a single-layer filter paper structure, which has limited filtration effect on impurities, making it inconvenient to thoroughly clean the engine oil.

[0012] The present invention is further configured such that a locking block is fixedly provided at the lower end of the filling block, the locking block cooperates with the inner wall of the limiting block, and the locking block and the limiting block are engaged and connected, thereby facilitating the connection between the filling block and the mounting cover.

[0013] Compared with the prior art, this utility model provides a long-life spin-on filter with the following advantages:

[0014] This utility model features an installation cover on which both the first and second filter elements are mounted, with a gap between them. When the entire oil filter is in normal use, engine oil enters the oil filter through the inlet on the top cover, pushing the check valve and flowing into the housing. The oil first passes through the first filter element, which adsorbs most of the impurities in the oil. The oil that has passed through the first filter element enters the space between the first and second filter elements and comes into contact with the surface of the second filter element, where it adsorbs the remaining impurities in the oil again. This facilitates the thorough removal of impurities from the oil.

[0015] This invention features a support base inside the bottom cover, on which a rotating frame is rotatably mounted. When the first and second filter elements accumulate a large amount of metal debris, the machine stops operating, preventing oil from entering the filter. The bottom cover is then removed, and the rotating frame is rotated. The rotating frame, along with a fixed column and a protruding block on the fixed column, contacts the first and second filter elements, causing them to be shaken and dislodged. This facilitates the removal of some metal debris and impurities, making the entire filter reusable.

[0016] This invention, by setting a passage groove and a filling block at the upper end of the mounting cover, allows for emergency use of the oil filter when the first filter element becomes unusable after a certain period of use. The oil filter is removed from the machine, the top cover of the entire oil filter is opened, and the filling block on the mounting cover is removed from the passage groove. The oil filter is then reassembled and installed on the machine. When oil enters the oil filter, the inclined structure of the guide ring at the upper end of the mounting cover guides the oil to the passage groove. The oil then enters between the first and second filter elements through the passage groove, where it is filtered by the second filter element. This extends the lifespan of the entire oil filter and facilitates emergency use. Attached Figure Description

[0029] More specifically, the engine oil is filtered through the combination of the first filter element 4 and the second filter element 5.

[0030] Please see Figures 1-5As an implementation method for emergency use of the entire filter: a guide ring 21 is fixedly installed on the mounting cover 6. The guide ring 21 is sloping.

[0031] Specifically, when the first filter element 4 becomes unusable after a certain period of use, but an oil filter is needed for emergency use, the oil filter is removed from the machine, the top cover 2 of the entire oil filter is opened, the filler block 23 on the mounting cover 6 is removed from the passage groove 22, the oil filter is reassembled, and the oil filter is installed on the machine. When oil enters the oil filter, the oil is guided to the passage groove 22 through the ramp structure of the guide ring 21 at the upper end of the mounting cover 6. The oil enters between the first filter element 4 and the second filter element 5 through the passage groove 22, thereby filtering the oil through the second filter element 5.

[0032] Please refer to Figure 1-5 As an implementation method to extend the service life of the filter: A bottom shell 12 is detachably mounted on the bottom cover 3, and a support base 13 is provided inside the bottom cover 3. A limit ring is provided on the bottom shell 12, and the limit ring cooperates with the support base 13. Support rings 14 are fixedly mounted on both the support base 13 and the bottom cover 3, and the support rings 14 cooperate with the first filter element 4 and the second filter element 5. A connecting ring 15 is fixedly mounted on the lower end of the bottom cover 3, and threads are provided on the inner wall of the connecting ring 15 and the outer wall of the bottom shell 12.

[0033] Specifically, when a large amount of metal debris is adsorbed in the first filter element 4 and the second filter element 5, the machine is stopped, and the oil no longer enters the oil filter. The bottom shell 12 is removed from the bottom cover 3, and the rotating frame 17 is rotated. The fixed column 18 and the protruding block 19 on the fixed column 18 contact the first filter element 4 and the second filter element 5, and the surfaces of the first filter element 4 and the second filter element 5 are moved to shake off the metal debris and other impurities, thus facilitating the removal of some metal debris or impurities.

[0034] In summary, when using it as a whole:

[0035] When the entire oil filter is in normal use, the oil enters the oil filter through the oil inlet 10 on the top cover 2, pushes the check valve 8, and flows into the housing 1. The oil first passes through the first filter element 4, which adsorbs most of the impurities in the oil. The oil that has passed through the first filter element 4 enters the space between the first filter element 4 and the second filter element 5, and comes into contact with the surface of the second filter element 5. The remaining impurities in the oil are then adsorbed again by the surface of the second filter element 5.

[0036] When a large amount of metal debris is adsorbed in the first filter element 4 and the second filter element 5, the machine is stopped, and the oil no longer enters the oil filter. The bottom shell 12 is removed from the bottom cover 3, and the rotating frame 17 is rotated. The fixed column 18 and the protruding block 19 on the fixed column 18 contact the first filter element 4 and the second filter element 5, and the surfaces of the first filter element 4 and the second filter element 5 are shaken off, thereby facilitating the removal of some metal debris or impurities.

[0037] When the first filter element 4 becomes unusable after a certain period of use, but an oil filter is needed for emergency use, the oil filter is removed from the machine, the top cover 2 of the entire oil filter is opened, the filler block 23 on the mounting cover 6 is removed from the passage groove 22, the oil filter is reassembled, and the oil filter is installed on the machine. When oil enters the oil filter, the oil is guided to the passage groove 22 through the ramp structure of the guide ring 21 at the upper end of the mounting cover 6. The oil enters between the first filter element 4 and the second filter element 5 through the passage groove 22, thereby filtering the oil through the second filter element 5.
