Description

Technical Field

[0001] The present invention relates to the field of filtering devices, and more particularly, to a self-cleaning and recyclable filter element. Background Art

[0002] A filter element is a professional term for the function of filtration and purification, which is a simple device for purifying the original fluid resources and facilitating the separation of resources. At present, filter elements are mainly used in filtration industries such as oil filtration, air filtration, and water filtration.

[0003] At present, the existing filter element technologies at home and abroad mainly focus on two categories: disposable filter elements and washable filter elements; after the disposable filter elements are used, they need to be completely replaced, resulting in waste of resources and increased processing costs; although the washable filter elements can be reused, the cleaning process is complex and cumbersome, requiring manual disassembly, cleaning, drying, etc., and the cleaning efficiency is low, which is easy to cause secondary pollution and affect the service life of the filter element.

[0004] In view of the above problems, some solutions have also been given in the prior art. For example, the Chinese utility model patent with the publication number CN221267373U discloses a filter element with a self-cleaning function. By setting a motor to drive the rotation of a rotating shaft, two groups of cleaning brushes rotate to clean the filter element. At the same time, when the small gear rotates, it drives the telescopic rod and the spring to expand and contract, and makes the embedding rod embed into the bristles of the cleaning brush to move downward, so that the stains in the gaps of the filter element are cleaned while the cleaning brush cleans the filter element, thereby improving the self-cleaning effect of the cleaning brush on the surface of the filter element; although the prior art can clean the filter element without removing it, in the actual use process, the stains separated from the filter element will attach to the surface of the filter element again with the water flow, seriously affecting the cleaning effect, and as the stains accumulate, there is still a risk of blockage of the filter element, so the user still needs to replace it, or disassemble the filter element to clean the stains, which seriously affects the cleaning efficiency of the filter element.

[0011] Further, a collection groove is formed on the scraping plate. A striking plate cooperating with the collection groove is fixedly installed on the side wall of the installation groove.

[0012] Further, an installation frame is fixedly installed in the filter. An elastic pad fixedly connected to the filter element body is fixedly installed on the top wall of the installation frame. A pushing block is fixedly installed on the bottom wall of the filter element body, and the side wall of the side away from the filter element body of the pushing block is an inclined surface.

[0016] Further, a baffle is fixedly mounted on the side wall of the filter element body close to the elastic pad, and the baffle can block the collection port.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this solution, by setting up a stain box, during the process of water flow passing through the filter, the impeller and the rotating rod drive the scraper to rotate, and the stains on the filter element body are cleaned. Then, under the action of centrifugal force, the stains enter the stain box through the collection port.

Since the first bevel gear meshes with the second bevel gear, then during the rotation of the second bevel gear, the first bevel gear drives the second bevel gear to rotate. Then, during the rotation of the second bevel gear, the cleaning rod drives the brush to rotate. Then, during the rotation of the brush, the residual fine particle impurities on the filter element body can be cleaned twice. And during the rotation of the brush, it will impact the striking plate. Then, under the action of inertia, the stains adhered to the brush are separated from the brush and enter the collection tank along the striking plate, so as to prevent the stains on the brush from adhering to the surface of the filter element body again, further improving the cleaning effect of the filter element body; (3) In this solution, through the setting of the elastic pad, during the rotation of the rotating rod, the filter element body can be driven to reciprocate through the push rod, the push block and the elastic pad, which can make the stains on the surface of the filter element body become loose, so as to facilitate the scraper and the brush to clean the stains. And during the compression of the elastic pad, the water flow in the cavity is squeezed and flows through the drain valve and the first water pipe into the linkage cavity, and then flows through the second water pipe on the linkage cavity into the collection tank, and then drives the stains in the collection tank to quickly move to the edge of the filter element, so as to facilitate the stains to flow into the stain box through the collection port, preventing the stains from adhering to the surface of the brush again and affecting the cleaning effect of the filter element body, and further improving the cleaning effect of the filter element body.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 9 , a self-cleaning and recyclable filter element, including a filter 1, a filter element body 2 is arranged inside the filter 1, a water inlet pipe 4 and a drain pipe 3 are respectively communicated on both sides of the filter 1, and a cleaning component 5 is arranged on the filter element body 2; The cleaning component 5 includes a mounting plate 501 fixedly installed on the filter 1, a rotating rod 502 is rotatably installed on the mounting plate 501, an impeller 503 matched with the drain pipe 3 is fixedly installed on the bottom wall of the rotating rod 502, an annular groove is formed and installed on the filter element body 2, a scraping plate 504 is rotatably installed in the annular groove, a sliding groove 505 is formed on the rotating rod 502, and a sliding block 506 slidably matched with the sliding groove 505 is fixedly installed on the scraping plate 504. A stain box 507 is fixedly installed on the filter 1, a stain opening is formed on the filter 1, a collection opening is formed on the stain box 507, a horizontal rod 508 is rotatably installed on the collection opening, a blocking plate 509 for blocking the collection opening is fixedly installed on the horizontal rod 508, a first magnet 510 is embedded on the blocking plate 509, a second magnet 511 is embedded on the scraping plate 504, and the first magnet 510 and the second magnet 511 repel each other. A torsion spring 512 is jointly installed between the horizontal rod 508 and the stain box 507, and a sewage discharge component 6 is arranged on the stain box 507.

[0022] The sewage discharge component 6 includes a sewage discharge port 601 formed on the bottom wall of the stain box 507, a sealing plate 602 is slidably installed on the bottom wall of the stain box 507, a connecting rod 603 fixedly connected with the sealing plate 602 is inserted on the side wall of the stain box 507, an elastic air bag 604 is jointly installed between the connecting rod 603 and the stain box 507, an installation cavity 605 is formed on the stain box 507, and a fixing rod 606 is slidably installed in the installation cavity 605.

[0023] A fixing groove 607 matched with the fixing rod 606 is formed on the horizontal rod 508, a communicating pipe 608 communicating with the installation cavity 605 is inserted on the elastic air bag 604, and a protective ring 9 is fixedly installed on the scraping plate 504.

[0024] During use, water flows into the filter 1 through the water inlet pipe 4 and flows out through the drain pipe 3. Then, during the process of the water flowing through the filter 1, the filter element body 2 can filter the stains in the water flow. At the same time, during the process of the water flow passing through the filter 1 and entering the drain pipe 3, the water flow will impact the impeller 503 and drive the impeller 503 to rotate. Then, during the rotation of the impeller 503, the rotating rod 502 can be driven to rotate. During the rotation of the rotating rod 502, the scraper 504 is driven to rotate. During the rotation of the scraper 504, the stains on the surface of the filter element body 2 can be driven to rotate. Then, under the action of centrifugal force, the stains gradually move away from the rotating rod 502. Then, during the process of the stains moving away from the rotating rod 502, they gradually enter the stain box 507 through the stain port and the collection port, thereby preventing the stains from adhering to the surface of the filter element body 2 again and causing the filter element body 2 to be blocked, realizing the function that the filter element body 2 can be automatically cleaned and recycled.

[0025] During the rotation of the scraper 504, the second magnet 511 is driven to rotate. Then, during the rotation of the second magnet 511, it gradually approaches the first magnet 510. Then, under the action of the repulsive force, the first magnet 510 drives the blocking plate 509 to rotate around the horizontal rod 508. At this time, the torsion spring 512 is deformed and has a tendency to recover. And in the actual production and application process, those skilled in the art can select appropriate materials according to the specific application situation, so that the magnetic force between the first magnet 510 and the second magnet 511 can drive the scraper blocking plate 509 to rotate. During the rotation of the blocking plate 509 around the horizontal rod 508, it gradually disengages from the collection port. At this time, the stains can normally enter the stain box 507 through the collection port. Then, when the scraper 504 is far away from the collection port, the scraper 504 drives the second magnet 511 to move away from the first magnet 510. At this time, the torsion spring 512 drives the blocking plate 509 to reset through the horizontal rod 508 and blocks the collection port, which can prevent the stains in the stain box 507 from adhering to the surface of the filter element body 2 again through the collection port when the scraper 504 is far away from the collection port, playing a role in improving the cleaning effect of the filter element body 2.

[0026] When there is too much dirt in the dirt box 507, the user can slowly pull the connecting rod 603. At this time, the elastic airbag 604 is stretched, and then the elastic airbag 604 inhales air from the installation cavity 605 through the connecting pipe 608. Then, the pressure in the installation cavity 605 decreases, and under the action of the pressure in the installation cavity 605, the fixing rod 606 has a tendency to move into the fixing groove 607. And during the rotation of the horizontal rod 508, the fixing groove 607 is driven to rotate. When the fixing groove 607 contacts the fixing rod 606, the air flow will drive the fixing rod 606 to insert into the fixing groove 607 and fix the horizontal rod 508. That is, at this time, the blocking plate 509 is fixed to always block the collection port, and the dirt box 507 is no longer connected to the filter 1. Then, as the connecting rod 603 moves, the connecting rod 603 drives the sealing plate 602 to move and separate from the sewage outlet 601. At this time, under the action of gravity, the dirt in the dirt box 507 flows to the outside through the sewage outlet 601, thus preventing too much dirt in the dirt box 507 from affecting the normal flow of dirt in the filter 1 into the dirt box 507, further improving the cleaning effect, and eliminating the need for the user to close the filter 1 to clean the dirt box 507, improving the cleaning efficiency of the filter element body 2.

[0027] As Figure 3 , Figure 6 , Figure 7 shown, an installation groove is formed in the scraping plate 504, a cleaning rod 701 is rotatably installed in the installation groove, bristles 702 are uniformly fixedly installed on the cleaning rod 701, a first bevel gear 703 is fixedly installed on the filter element body 2, and a second bevel gear 704 meshing with the first bevel gear 703 is fixedly installed on the cleaning rod 701.

[0028] A collection groove 705 is formed in the scraping plate 504, and a striking plate 706 cooperating with the collection groove 705 is fixedly installed on the side wall of the installation groove.

[0029] By adopting the above technical solution, during the rotation of the scraping plate 504, the second bevel gear 704 is driven to make a circular motion around the first bevel gear 703. Since the first bevel gear 703 meshes with the second bevel gear 704, during the rotation of the second bevel gear 704, the first bevel gear 703 drives the second bevel gear 704 to rotate. Then, during the rotation of the second bevel gear 704, the bristles 702 are driven to rotate through the cleaning rod 701. Then, during the rotation of the bristles 702, the residual fine particle impurities on the filter element body 2 can be cleaned for the second time. And during the rotation of the bristles 702, they will collide with the striking plate 706. Then, under the action of inertia, the dirt adhered to the bristles 702 is separated from the bristles 702 and enters the collection groove 705 along the striking plate 706, thus preventing the dirt on the bristles 702 from soiling the surface of the filter element body 2 again, further improving the cleaning effect of the filter element body 2.

[0030] During the rotation of the scraper 504, the protective ring 9 is driven to rotate. Then, during the rotation of the protective ring 9, the stains in the chute 505, the first bevel gear 703, the second bevel gear 704 and the filter 1 can be separated, so as to prevent the stains from adhering to the chute 505, the first bevel gear 703, the second bevel gear 704 and affecting the normal operation of the device.

[0031] As Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 As shown in

[0032] An installation frame 801 is fixedly installed in the filter 1. An elastic pad 802 fixedly connected to the filter element body 2 is fixedly installed on the top wall of the installation frame 801. A push block 803 is fixedly installed on the bottom wall of the filter element body 2, and the side wall of the push block 803 away from the filter element body 2 is an inclined surface. A push rod 804 cooperating with the push block 803 is fixedly installed on the rotating rod 502.

[0033] A cavity 805 is formed in the elastic pad 802. A water inlet valve 806 is inserted into the cavity 805, and a drain valve 807 is inserted into the cavity 805. A first water pipe 808 is inserted into the output end of the drain valve 807. The rotating rod 502 is fixedly installed with a first linkage ring 809.

[0034] By adopting the above technical solution, during the rotation of the rotating rod 502, the push rod 804 is driven to rotate. Then, during the rotation of the push rod 804, it gradually contacts the push block 803 and applies an upward thrust to the push block 803. Then, under the action of the thrust, the push block 803 drives the filter element body 2 to move upward. During the upward movement of the filter element, the slider 506 is driven by the scraper 504 to move upward along the chute 505. At the same time, during the upward movement of the filter element body 2, the elastic pad 802 will be stretched. Then, after the push rod 804 is separated from the push block 803, the elastic pad 802 contracts and drives the filter element body 2 to move downward. That is, during the rotation of the rotating rod 502, the filter element body 2 can be driven to swing back and forth by the push rod 804 and the push block 803. During the back-and-forth swing of the filter element body 2, the stains on the surface of the filter element body 2 can be loosened, so as to facilitate the cleaning of the stains by the scraper 504 and the brush bristles 702, and further improve the cleaning effect of the filter element body 2.

[0035] During the stretching process of the elastic pad 802, the cavity 805 sucks in the filtered water flow through the water inlet valve 806. Then, during the compression process of the elastic pad 802, the water flow in the cavity 805 is squeezed and flows through the drain valve 807 and the first water pipe 808 into the linkage cavity 811, and then flows through the second water pipe 812 on the linkage cavity 811 into the collection tank 705. Then, it drives the stains in the collection tank 705 to quickly move towards the edge of the filter element, facilitating the stains to flow through the collection port into the stain box 507, avoiding the stains from adhering to the surface of the brush bristles 702 again and affecting the cleaning effect of the filter element body 2, thus playing a role in improving the cleaning effect of the filter element body 2.

[0036] As Figure 2 , Figure 6 shown, two sets of the push block 803 and the push rod 804 are provided, and the surface of the slider 506 is a smooth mirror surface.

[0037] By adopting the above technical solution, during the process of the push rod 804 driving the filter element body 2 to reciprocate through the push block 803, by setting two sets of the push block 803 and the push rod 804, it is possible to avoid uneven force during the process of pushing the filter element body 2 to move and cause the filter element body 2 to shift and get stuck, thus playing a role in ensuring the normal movement of the filter element body 2; and during the process of the filter element body 2 driving the slider 506 to move along the chute 505 through the scraper 504, since at this time the rotating rod 502 drives the slider 506 to rotate through the chute 505, there is a force acting between the slider 506 and the chute 505. By making the surface of the slider 506 a smooth mirror surface, the friction between the slider 506 and the chute 505 can be reduced, thereby ensuring that the slider 506 can move normally along the chute 505.

[0038] As Figure 3 shown, a baffle 10 is fixedly installed on the side wall of the filter element body 2 close to the elastic pad 802, and the baffle 10 can block the collection port.

[0039] By adopting the above technical solution, during the movement of the filter element body 2, the baffle 10 is driven to move. At this time, the baffle 10 can block the collection port on the side of the filter plate close to the elastic pad 802, thereby preventing stains from entering the gap between the elastic pad 802 and the filter 1 and affecting the normal movement of the filter element body 2, thus playing a role in ensuring the normal movement of the filter element body 2.

[0040] Usage method: When in use, water flows into the filter 1 through the water inlet pipe 4 and flows out through the drain pipe 3. Then, during the process of the water flowing through the filter 1, the filter element body 2 can filter the stains in the water flow. At the same time, during the process of the water flowing through the filter 1 and into the drain pipe 3, the water flow will impact the impeller 503 and drive the impeller 503 to rotate. Then, during the rotation of the impeller 503, the rotating rod 502 can be driven to rotate. During the rotation of the rotating rod 502, the scraping plate 504 is driven to rotate. During the rotation of the scraping plate 504, the stains on the surface of the filter element body 2 can be driven to rotate. Then, under the action of centrifugal force, the stains gradually move away from the rotating rod 502, and then gradually enter the stain box 507 through the stain port and the collection port during the process of the stains moving away from the rotating rod 502; during the rotation of the scraping plate 504, the second magnet 511 is driven to rotate. Then, during the rotation of the second magnet 511, it gradually approaches the first magnet 510. Then, under the action of the repulsive force, the first magnet 510 drives the blocking plate 509 to rotate around the horizontal rod 508. At this time, the torsion spring 512 starts to store energy and has a tendency to recover. During the rotation of the blocking plate 509 around the horizontal rod 508, it gradually disengages from the collection port. At this time, the stains can normally enter the stain box 507 through the collection port. Then, when the scraping plate 504 moves away from the collection port, the scraping plate 504 drives the second magnet 511 to move away from the first magnet 510. At this time, the torsion spring 512 drives the blocking plate 509 to reset through the horizontal rod 508 and blocks the collection port; when there is too much stain in the stain box 507, the user can slowly pull the connecting rod 603. At this time, the elastic airbag 604 is stretched, and then the elastic airbag 604 inhales air from the installation cavity 605 through the connecting pipe 608. Then, under the action of the air flow, the fixed rod 606 has a tendency to move into the fixed groove 607, and the fixed groove 607 is driven to rotate during the rotation of the horizontal rod 508. When the fixed groove 607 contacts the fixed rod 606, the air flow will drive the fixed rod 606 to insert into the fixed groove 607 and fix the horizontal rod 508, that is, at this time, the blocking plate 509 is fixed to always block the collection port and make the stain box 507 no longer communicate with the filter 1. Then, as the connecting rod 603 moves, the connecting rod 603 drives the sealing plate 602 to move and disengage from the sewage discharge port 601. At this time, under the action of gravity, the stains in the stain box 507 flow to the outside through the sewage discharge port 601;During the rotation of the squeegee 504, the second bevel gear 704 is driven to rotate. Since the first bevel gear 703 meshes with the second bevel gear 704, then during the rotation of the second bevel gear 704, the first bevel gear 703 drives the second bevel gear 704 to rotate. Then during the rotation of the second bevel gear 704, the cleaning rod 701 drives the bristles 702 to rotate. Then during the rotation of the bristles 702, the residual fine particle impurities on the filter element body 2 can be cleaned twice. And during the rotation of the bristles 702, they will collide with the striking plate 706. Then under the action of inertia, the stains adhered to the bristles 702 are separated from the bristles 702 and enter the collection tank 705 along the striking plate 706; During the process of the elastic pad 802 being stretched, the cavity 805 sucks in the filtered water flow through the water inlet valve 806. Then during the process of the elastic pad 802 being compressed, the water flow in the cavity 805 is squeezed and flows through the drain valve 807 and the first water pipe 808 into the linkage cavity 811, and flows through the second water pipe 812 on the linkage cavity 811 into the collection tank 705. Then it drives the stains in the collection tank 705 to quickly move towards the edge of the filter element, so as to facilitate the stains to flow into the stain box 507 through the collection port, and avoid the stains from adhering to the surface of the bristles 702 again, affecting the cleaning effect of the filter element body 2.;

[0041] The above is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
