Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0024] Reference Figures 1-5 A filter for easy cleaning of the filter element includes a filter element 4 placed in the center of a collection box 7. The top of the collection box 7 has multiple equidistantly distributed insertion holes 13, each containing a support post 3. A housing 2 is welded to the top of the support post 3. A geared motor 1, model NB060-L1-5-S2-P2, is bolted to the top of the housing 2. One end of the output shaft of the geared motor 1 passes through the housing 2 and is bolted to a connecting frame 5. A fixing ring is welded to the outside of the connecting frame 5. The bottom of the fixing ring... Multiple equally spaced slots are provided, and connecting posts 9 are inserted into the slots. A roller brush 6 for cleaning the surface of the filter element 4 is fixed to the outside of the connecting posts 9 by bolts. The bristles of the roller brush 6 are made of nylon. When cleaning is required, the reduction motor 1 is started, which drives the connecting frame 5 to rotate. The connecting frame 5 drives the fixing ring to rotate, which drives the connecting post 9 to rotate. The connecting post 9 drives the roller brush 6 to rotate, so that the roller brush 6 cleans the outer circumference of the filter element 4, thereby facilitating the cleaning and unblocking of the filter element 4, saving time and effort.
[0025] Multiple limiting shells 14 corresponding to connecting posts 9 are fixed to the outer side of the fixing ring by bolts. A sliding hole is opened on one side of the limiting shell 14, and a sliding post 18 is slidably connected in the sliding hole. A pressing block 17 is provided on the outer wall of one side of the limiting shell 14, and the pressing block 17 fits against the limiting shell 14. A through groove with open upper and lower sides is opened on one side of the pressing block 17. One end of the sliding post 18 extends into the through groove and is rotatably connected to the pressing block 17 through the connecting shaft 16. An insert 15 is welded to the other end of the sliding post 18. A groove is opened on one side of the connecting post 9, and the insert 15 passes through the fixing ring and is inserted into the groove.
[0026] The pressing block 17 flips up and down through the connecting shaft 16. With the through groove, the sliding column 18 will not block the pressing block 17 during the up and down rotation of the pressing block 17 through the connecting shaft 16, which makes it easy for the insert block 15 to disengage from the connecting column 9 and facilitates disassembly.
[0027] The bottom of the collection box 7 is provided with connecting screws to fix the support column 3. When the roller brush 6 needs to be disassembled, the connecting screws at the bottom of the collection box 7 are removed. At this time, the support column 3 can be taken out from the insertion hole 13. Then, the pressing block 17 is rotated through the connecting shaft 16. Since the pressing block 17 is attached to the limiting shell 14, the pressing block 17 will pull the sliding column 18 to move out of the limiting shell 14 during the rotation. The sliding column 18 will drive the insertion block 15 to move, so that the insertion block 15 is disengaged from the groove on the connecting column 9. At this time, the connecting column 9 can be removed from the fixing ring, thereby disassembling and replacing the roller brush 6, which facilitates the disassembly and cleaning of the roller brush 6 and improves the convenience of disassembling the roller brush 6.
[0028] In this utility model, a spring is sleeved on the outer side of the sliding column 18, and the two ends of the spring are fixed to the limiting shell 14 and the insert block 15 respectively. With the setting of the spring, when the pressing block 17 is in contact with the limiting shell 14, the pressing block 17 will be tightly in contact with the limiting shell 14 under the action of the spring, so that the pressing block 17 will not easily rotate without the action of human force. The connecting column 9 is inserted into the slot at the bottom of the fixing ring so that the connecting column 9 will not move horizontally. The insert block 15 is inserted into the outer wall of the connecting column 9 to limit the connecting column 9 in the vertical direction.
[0029] In particular, an annular plate 10 supporting the connecting column 9 is fixed to the top of the collection box 7 by bolts, and the filter element 4 passes through the annular plate 10. An annular groove 19 is opened at the top of the annular plate 10, and an installation groove is opened at the bottom of the connecting column 9. A ball bearing 8 is rolled in the installation groove and rolls along the groove direction of the annular groove 19. During the rotation of the connecting column 9, the ball bearing 8 will drive the ball bearing 8 to roll along the annular groove 19. Under the action of the ball bearing 8, the connecting column 9 can be supported and the friction force of the connecting column 9 driving the roller brush 6 to rotate is reduced.
[0030] It should be noted that the collection box 7 is equipped with a guide ring 12. Multiple support rods 11 are welded to the bottom of the guide ring 12, and the support rods 11 are fixed to the collection box 7. The guide ring 12 is inverted funnel-shaped. The filter element 4 passes through the inner ring of the guide ring 12 and is in contact with the guide ring 12. When the roller brush 6 cleans the surface of the filter element 4, the impurities that are cleaned off will enter the collection box 7 through the guide ring 12, realizing the function of guiding the impurities, so that the collection box 7 can collect the cleaned impurities uniformly.
[0031] Working principle: When cleaning is required, the reduction motor 1 is started, which drives the connecting frame 5 to rotate. The connecting frame 5 drives the fixed ring to rotate, which in turn drives the connecting column 9 to rotate. The connecting column 9 then drives the roller brush 6 to rotate, allowing the roller brush 6 to clean the outer circumference of the filter element 4, thus facilitating cleaning and unclogging the filter element 4, saving time and effort. During the rotation of the connecting column 9, the ball bearings 8 roll along the annular groove 19. The ball bearings 8 provide support for the connecting column 9 and reduce the friction that drives the roller brush 6 to rotate. When it is necessary to disassemble the roller brush 6, the collection box is removed. 7. Remove the connecting screws at the bottom. Then, the support column 3 can be removed from the insertion hole 13. Then, pull the pressing block 17 outward and rotate it around the connecting shaft 16. Finally, the pressing block 17 fits into the limiting shell 14. Therefore, during the rotation, the pressing block 17 will pull the sliding column 18 to move outward from the limiting shell 14. The sliding column 18 will drive the insertion block 15 to move, so that the insertion block 15 is disengaged from the groove on the connecting column 9. At this time, the connecting column 9 can be removed from the fixing ring, thereby disassembling and replacing the roller brush 6. This makes it easier to disassemble and clean the roller brush 6 and improves the convenience of disassembling the roller brush 6.
[0032] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
