[0030] In one embodiment of the present utility model, as Figure 1 , Figure 2 and Figure 3 shown, a new oil filter is provided, which includes a housing 1. A fixing frame 2 is fixedly connected to the outer wall of the housing 1. A connecting rod is rotatably connected inside the fixing frame 2. A filter housing 4 is fixedly connected to the inner wall of the housing 1. A filter element cylinder 5 is slidably connected inside the filter housing 4. A sealing ring 6 is fixedly connected to the outer wall of the filter element cylinder 5. A pin 7 is slidably connected inside the sealing ring 6. A long rod 8 is slidably connected inside the pin 7. The pin 7 is slidably connected inside the filter housing 4. A ball 11 is slidably connected inside the pin 7. The ball 11 is slidably connected inside the filter housing 4. A buckle assembly is arranged on the outer wall of the long rod 8. The buckle assembly includes a clamping plate 9. The clamping plate 9 is fixedly connected to the outer wall of the long rod 8. A first spring 10 is sleeved on the outer wall of the long rod 8. The upper end of the first spring 10 is fixedly connected to the lower surface of the clamping plate 9. The lower end of the first spring 10 is fixedly connected to the inside of the pin 7;

[0031] Specifically, first, the sealing ring 6 and the filter element cylinder 5 are fixed. The sealing ring 6 and the filter element cylinder 5 are placed inside the filter housing 4. The sealing ring 6 is attached to the inner wall of the filter housing 4. Then the pin 7 is inserted between the two. By pressing the long rod 8, the long rod 8 slides inside the pin 7. While sliding, it drives the clamping plate 9 to slide. There is also a first spring 10 between the clamping plate 9 and the pin 7. When the clamping plate 9 slides, it compresses the first spring 10. When the long rod 8 slides downward, it squeezes the two balls 11 to both sides, so as to clamp the two balls 11 inside the filter housing 4, achieving the effect of facilitating installation and fixation.

[0032] In another embodiment of the present utility model, as Figure 1 , Figure 2 and Figure 4, a threaded groove 12 is provided inside the filter element cylinder 5 of the new oil filter, an oil inlet hole 13 is provided inside the filter element cylinder 5, a filter hole 14 is provided inside the filter element cylinder 5, a filter cotton 15 is fixedly connected to the outer wall of the filter element cylinder 5, a conical block 16 is fixedly connected inside the filter housing 4, a sleeve 17 is fixedly connected inside the filter element cylinder 5, a fixing block 18 is fixedly connected inside the sleeve 17, a second spring 19 is provided inside the fixing block 18, and the outer wall of the second spring 19 is fixedly connected inside the fixing block 18. A connecting plate 20 is slidably connected inside the sleeve 17. The lower end of the second spring 19 is fixedly connected to the upper surface of the connecting plate 20. A hose 21 is fixedly connected inside the cover 1;

[0033] Specifically, first align the threaded groove 12 inside the filter element cylinder 5 with the position to be fixed, then lift the two connecting rods 3, and then rotate the two connecting rods 3, which also drives the cover 1 and the filter housing 4 to rotate together, and further drives the filter element cylinder 5 to rotate, so as to fix it at the required fixed position. The oil enters through the oil inlet hole 13 on the filter element cylinder 5 and is filtered by the filter cotton 15. After filtration, it returns to the machine through the filter hole 14 inside the filter element cylinder 5. If the filter cotton 15 is fully saturated with impurities and can no longer be used, the oil entering the filter element cylinder 5 at this time will bypass the filter cotton 15 and enter from the connecting plate 20 at the bottom of the filter element cylinder 5. The oil will lift the connecting plate 20 and enter the inside of the sleeve 17, so that it directly returns to the machine without passing through the filter, which will cause damage to the machine. At this time, the filter needs to be replaced. Similarly, rotate the two connecting rods 3 to disassemble it, but oil will leak out during the disassembly process. Therefore, a cover 1 is fixed to the outer walls of the two connecting rods 3. The spilled oil will be collected by the cover 1 and discharged through the hose 21 at the bottom of the cover 1, achieving the effect of convenient replacement.

[0034] Working principle: When the filter needs to be used, first align the threaded groove 12 inside the filter cartridge 5 with the position where it needs to be installed, then lift the two connecting rods 3 upward, and then rotate the two connecting rods 3 left and right. By rotating the connecting rods 3, the entire filter is driven to rotate and install on the machine. After the installation is completed, during the operation of the machine, the engine oil enters the inside of the filter cartridge 5 through the oil inlet hole 13 inside the filter cartridge 5, is filtered by the filter cotton 15, and the filtered engine oil returns to the inside of the machine through the filter holes 14, forming a cycle and filtering out impurities. When the filter cotton 15 fully absorbs impurities, it will affect the use effect. At this time, when the engine oil enters the inside of the filter cartridge 5 again, it will directly bypass the filter cotton 15 and enter from the bottom of the filter cartridge 5. The engine oil pushes up the connecting plate 20, enters the inside of the filter cartridge 5 through the sleeve 17 and then directly returns to the machine, which will affect the use of the machine. At this time, disassembly and replacement are required. Similarly, rotate the two connecting rods 3. To prevent the engine oil from soiling the hands, there is a cover 1 on the outer wall of the connecting rod 3. The engine oil generated during disassembly will be collected through the cover 1 and discharged through the hose 21. When the disassembly is completed, press the long rod 8 on the sealing ring 6. After the long rod 8 is pressed, it will slide inside the pin 7, and also drive the clamping plate 9 to compress the first spring 10. When the long rod 8 slides to the bottom position of the pin 7, the two marbles 11 will be stuck inside the filter housing 4 to form a fixation. Then press the long rod 8 to make it rebound and slide upward, and the two marbles 11 will return to the inside of the pin 7. Therefore, the sealing ring 6 and the filter cartridge 5 can be disassembled, and then a new sealing ring 6 and filter cartridge 5 can be replaced. Then install them in the same way, so as to achieve the effects of being convenient for disassembly, installation and fixation, and convenient for replacement.

[0035] The rest of this embodiment is the same as that of Embodiment 1. For the features not explained in this embodiment, the explanations of Embodiment 1 are adopted and will not be elaborated here.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
