Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology, specifically to an easy-to-clean automotive filter. Background Technology
[0002] Automotive filters are filters that filter impurities or gases. Common automotive filters include air filters, cabin air filters, oil filters, and fuel filters. Each type of filter filters different types of impurities, but they all basically filter impurities from air or liquids.
[0003] Current fuel filters are single, non-removable units. When the filter element reaches the end of its service life, disassembly is inconvenient. Even when the filter element has not yet fully reached the replacement standard and only needs cleaning to restore its filtration performance, because the filter element cannot be disassembled, repair personnel can only try to flush the entire filter. However, this method is difficult to thoroughly and effectively clean the inside of the filter element. Therefore, we have proposed an easy-to-clean automotive filter to solve the above problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides an easy-to-clean automotive filter, solving the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0008] An easy-to-clean automotive filter includes a filter housing with a retaining ring welded to it. A circular groove is formed on the inner bottom wall of the filter housing. A filter element is fitted inside the filter housing, engaging with the circular groove. A housing cover is movably contacted at the top of the filter housing. Four connecting blocks are welded to the bottom of the housing cover, and a locking groove is formed on one side of each connecting block. Multiple cavities are formed on the retaining ring, and rectangular blocks are welded to the inner top wall of each cavity. Rotatable connections are made to the rectangular blocks. The device includes a lead screw with a threaded locking block that engages with a locking groove. A first gear is welded to the end of the lead screw. A transmission rod is rotatably connected to the bottom inner wall of the cavity. A second gear is fixedly connected to the top of the transmission rod, meshing with the corresponding first gear. A rotating cover is rotatably connected to the top of the fixed ring. The bottom end of the transmission rod extends into the rotating cover and is welded with a third gear. An internal gear ring is fixedly connected to the inner wall of the rotating cover, meshing with the third gear.
[0009] Furthermore, the rotating cover is fitted onto the filter cylinder, and the rectangular block is provided with two limiting rods, the ends of which are fixedly connected to one side of the corresponding locking block.
[0010] Furthermore, the top of the cylinder cover is connected to and fixed with an outlet pipe, and the bottom of the filter cylinder is connected to and fixed with an inlet pipe.
[0011] Furthermore, the bottom of the fixing ring is provided with multiple fixing grooves, and a square is welded to one side of the rotating cover.
[0012] Furthermore, the block is provided with a T-shaped pin, which engages with one of the multiple fixing slots.
[0013] Furthermore, a limiting ring is welded onto the T-shaped pin, and a spring is fixedly connected between one side of the limiting ring and one side of the block, with the spring movably sleeved on the T-shaped pin.
[0014] Furthermore, a limiting hole is formed on the top inner wall of the cavity, and the inner wall of the limiting hole is in movable contact with the outer side of the corresponding connecting block.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides an easy-to-clean automotive filter, which has the following advantages:
[0017] This invention utilizes a rotating cover to rotate a third gear, which in turn rotates a transmission rod. As the transmission rod rotates, the second gear, fixedly connected to its top, rotates as well. Since the second gear meshes with the first gear, its rotation drives the first gear, which in turn rotates the lead screw. As the lead screw rotates, the locking blocks move away from the locking groove along the lead screw, gradually disengaging from the locking groove on one side of the connecting block. Once all the locking blocks have disengaged from the locking groove, the cover is no longer fixed. The cover can then be removed from the top of the filter cylinder for cleaning. After cleaning, the filter element is inserted into the circular groove on the inner wall of the bottom of the filter cylinder. The cover is then placed on top of the filter cylinder, at which point the connecting block enters the cavity. Next, the rotating cover is rotated in the opposite direction, following the reverse transmission sequence of the disassembly process, to insert the locking blocks into the locking groove on one side of the connecting block, firmly fixing the cover to the top of the filter cylinder. This facilitates convenient disassembly and installation of the filter element, making it easy to remove and clean the filter element. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example
[0028] like Figure 1-7As shown in the figure, an easy-to-clean car filter according to one embodiment of the present invention includes a filter cylinder 1, a fixing ring 2 welded to the filter cylinder 1, a circular groove 3 formed on the bottom inner wall of the filter cylinder 1, a filter element 4 fitted inside the filter cylinder 1, the filter element 4 being fitted into the circular groove 3, a cylinder cover 5 movably contacting the top of the filter cylinder 1, four connecting blocks 6 welded to the bottom of the cylinder cover 5, a locking groove 7 formed on one side of the connecting blocks 6, multiple cavities 8 formed on the fixing ring 2, a rectangular block 9 welded to the top inner wall of the cavity 8, and a wire rotatably connected to the rectangular block 9. A locking block 11 is threaded onto the rod 10 and engages with the locking groove 7. A first gear 12 is welded to the end of the rod 10. A transmission rod 13 is rotatably connected to the bottom inner wall of the cavity 8. A second gear 14 is fixedly connected to the top of the transmission rod 13 and meshes with the corresponding first gear 12. A rotating cover 16 is rotatably connected to the top of the fixing ring 2. The bottom end of the transmission rod 13 extends into the rotating cover 16 and is welded with a third gear 15. An internal gear ring 17 is fixedly connected to the inner wall of the rotating cover 16 and meshes with the third gear 15.
[0029] When using the filter element 4, if cleaning or replacement is required, first release the lock on the rotating cover 16, rotate the rotating cover 16. The rotation of the rotating cover 16 will drive the third gear 15 to rotate, which in turn will cause the transmission rod 13 to rotate. When the transmission rod 13 rotates, the second gear 14 fixedly connected to its top will rotate accordingly. Since the second gear 14 meshes with the first gear 12, the rotation of the second gear 14 will drive the first gear 12 to rotate, thereby causing the lead screw 10 to rotate. When the lead screw 10 rotates, the locking block 11 will move along the lead screw 10 away from the locking groove 7, gradually disengaging from the locking groove 7 on one side of the connecting block 6. When all the locking blocks are engaged, the locking block 11 will rotate away from the locking groove 7 on one side of the connecting block 6. After all blocks 11 are disengaged from the locking groove 7, the cover 5 is no longer fixed. At this time, the cover 5 can be removed from the top of the filter cylinder 1 to clean the filter element 4. After cleaning, the filter element 4 is inserted into the circular groove 3 on the inner wall of the bottom of the filter cylinder 1. The cover 5 is placed on the top of the filter cylinder 1. At this time, the connecting block 6 will enter the cavity 8. Then, the rotating cover 16 is rotated in the opposite direction. Following the transmission sequence opposite to the disassembly process, the locking block 11 is inserted into the locking groove 7 on one side of the connecting block 6, and the cover 5 is firmly fixed to the top of the filter cylinder 1. This realizes the convenient disassembly and installation of the filter element 4, making it easy to remove and clean the filter element 4. Then, the rotating cover 16 is fixed.
[0030] like Figure 7 As shown, in some embodiments, the rotating cover 16 is fitted onto the filter cylinder 1, and the rectangular block 9 is provided with two limiting rods 18, the ends of which are fixedly connected to one side of the corresponding locking block 11.
[0031] The limiting rod 18 is set to limit the movement of the locking block 11, so that the locking block 11 will not be displaced when it moves.
[0032] like Figure 1 As shown, in some embodiments, the top of the cylinder cover 5 is connected to and fixed with an outlet pipe 19, and the bottom of the filter cylinder 1 is connected to and fixed with an inlet pipe 20.
[0033] Fuel enters the filter from the inlet pipe 20 connected to the bottom of the filter housing 1. The fuel flows inside the filter housing 1 and passes through the filter element 4, which is installed inside the filter housing 1, to effectively intercept and filter impurities and particles in the fuel. The clean fuel then flows out from the outlet pipe 19, which is connected to and fixed at the top of the housing 5, and enters the subsequent stages of the vehicle's fuel system.
[0034] like Figure 6 As shown, in some embodiments, the bottom of the fixing ring 2 is provided with multiple fixing grooves 21, and a block 22 is welded to one side of the rotating cover 16. A T-shaped pin 23 is provided on the block 22. The T-shaped pin 23 is engaged with one of the fixing grooves 21. A limiting ring 24 is welded to the T-shaped pin 23. A spring 25 is fixedly connected between one side of the limiting ring 24 and one side of the block 22. The spring 25 is movably sleeved on the T-shaped pin 23.
[0035] Pull the T-pin 23 to disengage it from the current fixed groove 21. At this time, the rotating cover 16 is no longer fixed and can be rotated.
[0036] like Figure 3 As shown, in some embodiments, a limiting hole 26 is formed on the top inner wall of the cavity 8, and the inner wall of the limiting hole 26 is in movable contact with the outer side of the corresponding connecting block 6.
[0037] The limiting hole 26 is set to limit and position the connecting block 6.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
