Description

Technical Field

[0001] This invention relates to the field of filtration equipment technology, and more specifically, to a high-efficiency filtration device for a water purifier. Background Technology

[0002] With the increasing awareness of drinking water safety among residents, water purifiers have become essential equipment in homes, businesses, and public spaces. Among them, filter filtration is the core pretreatment step for intercepting particulate impurities (hair, dander, sediment, etc.), which directly affects the service life of subsequent filter cartridges and the quality of the output water.

[0003] Existing filter cleaning methods include manual and automatic cleaning: manual cleaning requires disassembling the filter, which is cumbersome and time-consuming. Disassembly can easily introduce external contaminants, causing secondary pollution. Furthermore, manual cleaning requires stopping the machine, leading to water supply interruptions. Even some devices attempt online cleaning, but due to structural design flaws (such as the lack of a continuously connected filter chamber), a continuous water supply cannot be guaranteed during cleaning, limiting the device's application in scenarios with continuous water demand. Existing automatic cleaning devices mostly only rinse the filter surface with water, which is ineffective at removing stubborn fibrous impurities such as hair and dander. Moreover, the cleaning brushes easily retain impurities; if not cleaned promptly, this can cause brush blockage and back-contaminate the filter. Therefore, we propose a high-efficiency filtration device for water purifiers. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency filtration device for water purifiers, which solves at least one of the above-mentioned technical problems.

[0005] This invention provides a high-efficiency filtration device for a water purifier, including an isolation box and a cleaning component. A support cylinder is installed inside the isolation box, and a cleaning hole is provided at the bottom of the support cylinder. A water tank is installed on the support cylinder, and the interior of the water tank is divided into an inlet area and an outlet area by a partition plate.

[0006] The filter assembly includes a support shaft rotatably mounted on an isolation box. The support shaft is connected to the output end of a geared motor. Several isolation plates are mounted on the support shaft. The isolation plates rotate inside the support cylinder and divide the support cylinder into several filter chambers. Filter screens are mounted on the isolation plates and divide the filter chambers into filter compartments and outlet compartments. The filter compartments are connected to the inlet area, and the outlet compartments are connected to the outlet area.

[0007] When the filter screen rotates into the cleaning hole, its axis is collinear with the rotation axis of the cleaning component. When the cleaning component rotates, it can clean the surface of the filter screen.

[0008] As a further description of the above technical solution, two sealing plates are fixedly installed at both ends of the support shaft. The sealing plates rotate inside the support cylinder, and the end face of the sealing plate is in contact with the inner end face of the support cylinder.

[0009] As a further description of the above technical solution, the support cylinder is provided with a first water inlet hole and two sets of second water inlets communicating with the water inlet area, and the support cylinder is provided with a first water outlet hole and two sets of second water outlet holes communicating with the water outlet area. Both the first water inlet hole and the first water outlet hole are arc-shaped.

[0010] As a further description of the above technical solution, the bottom of the water tank is at the same height as the bottom of the second water inlet.

[0011] As a further description of the above technical solution, the filter chamber is provided with liquid inlet holes. The two liquid inlet holes on the upper side are connected to the water inlet area of ​​the water tank through the first water inlet hole, and the two liquid inlet holes on the lower side are connected to the water inlet area of ​​the water tank through the second water inlet hole. The water outlet chamber is provided with liquid outlet holes. The two liquid outlet holes on the upper side are connected to the water outlet area of ​​the water tank through the first water outlet hole, and the two liquid outlet holes on the lower side are connected to the water outlet area of ​​the water tank through the second water outlet hole.

[0012] As a further description of the above technical solution, the cleaning component includes a support tube rotatably mounted on the isolation box, the support tube being connected to the output end of a corresponding geared motor, a support frame being mounted on the support tube, and a brush being fixedly mounted on the support frame.

[0013] As a further description of the above technical solution, the support frame is provided with a liquid inlet groove, and the liquid inlet groove is provided with a number of water spray holes distributed in the gaps of the brushes. The inside of the support tube is connected to the liquid inlet groove through a connecting pipe, and the liquid supply device is connected to the water inlet end of the support tube through a water sliding ring.

[0014] As a further description of the above technical solution, the arc length of the filter screen is less than half the arc length of the entire circle.

[0015] As a further description of the above technical solution, a sealing ring is installed on the sealing plate.

[0016] As a further description of the above technical solution, angle sensors are provided on both the support shaft and the support tube.

[0017] By adopting the above technical solution, during filtration, the empty filter chamber is at the bottom. When the control valve is opened, the water flows into the water inlet area of ​​the water tank through the inlet pipe, and then enters the filter chamber through the first and second inlet holes and the liquid inlet hole. After being filtered by the filter screen, it enters the outlet chamber, and then enters the outlet area of ​​the water tank through the liquid outlet hole, the first outlet hole and the second outlet hole. Finally, it is transported to the subsequent treatment equipment through the outlet pipe at the bottom.

[0018] When cleaning the filter screen of the filter device regularly, the output end of the lower geared motor drives the support tube to rotate, and the support tube drives the support frame and brush to rotate, so that the head of the brush faces down. The output end of the upper geared motor drives the support shaft, isolation plate, sealing plate and filter screen to rotate, so that the filter screen rotates to the cleaning hole position. At this time, the axis of the filter screen in the cleaning hole is collinear with the axis of the support tube.

[0019] During the rotation of the sealing plate, the two liquid inlets on the lower side quickly separate from the second water inlet, and the two liquid outlets on the lower side quickly separate from the second water outlet. The second water inlet and the second water outlet are blocked by the sealing plate and cannot supply or discharge liquid. At least one liquid inlet on the upper side can remain connected to the first water inlet during the rotation, and the corresponding liquid outlet can also remain connected to the first water outlet during the rotation, thus ensuring uninterrupted filtration. After the filter screen completes one position switch, the liquid inlet and liquid outlet in the cleaning hole are blocked by the support cylinder, while the other liquid inlet and liquid outlet are connected to the water inlet and water outlet areas of the water tank, improving the filtration efficiency after switching and reducing the impact of cleaning on the filtration volume.

[0020] During cleaning, the liquid supply equipment provides pressurized water to the support pipe through the water sliding ring. The pressurized water enters the liquid inlet tank through the connecting pipe and is quickly sprayed out from the spray hole. The output end of the geared motor drives the support pipe, support frame and brush to rotate. When the brush rotates, its end can contact the surface of the filter screen and, together with the water spray, impact the filter screen, thereby achieving efficient cleaning of the filter screen. When the brush detaches from the filter screen, the sprayed water flow can wash away the fiber impurities on the brush, achieving simultaneous cleaning of impurities on the brush. The cleaned impurities fall into the bottom of the isolation box and are discharged from the drain port opened at the bottom of the isolation box.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] 1. This invention, through the design of an arc-shaped first water inlet / outlet hole, combined with a multi-filter chamber rotation mechanism, ensures that at least one set of filter chambers is always in working condition during rotation, and at least three sets of filter chambers are always in working condition during cleaning, completely avoiding the problem of traditional filter cleaning requiring machine shutdown, and ensuring continuous water supply needs in commercial / public scenarios.

[0023] 2. When the brush of this invention rotates, it contacts the inner wall of the filter screen to scrape away impurities. At the same time, the high-pressure water sprayed from the water spray hole not only impacts the filter screen to enhance the cleaning power, but also washes away the fibers and other impurities remaining on the surface of the filter screen when the brush leaves the filter screen. Through the dual design of cleaning the filter screen and self-cleaning brush, not only is the cleanliness of the filter screen improved, but the service life of the brush is also extended and the frequency of brush replacement is reduced.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 9 This embodiment discloses a high-efficiency filtration device for a water purifier, including an isolation box 1. A support cylinder 2 is fixedly installed inside the isolation box 1. A cleaning hole 21 is opened at the bottom of the support cylinder 2. A water tank 22 is fixedly installed at the end of the support cylinder 2. A partition plate 23 is fixedly installed inside the water tank 22, dividing the water tank 22 into an inlet area and an outlet area. A first inlet hole 24 communicating with the inlet area and two sets of second inlet holes 25 are opened on the support cylinder 2. The first inlet hole 24 is arc-shaped, and its maximum water inflow is greater than that of the second inlet holes 25. The first inlet hole 24 is located at the second inlet hole 25. On the upper side, the support cylinder 2 has a first water outlet 26 communicating with the water outlet area and two sets of second water outlets 27. The first water outlet 26 is arc-shaped, and its maximum water output is greater than that of the second water outlets 27. The first water outlet 26 is located above the second water outlets 27. A water inlet pipe 28 communicating with the water inlet area is installed on the water tank 22. A control valve 29 is installed on the water inlet pipe 28 to control the entry of external water to be filtered into the water tank 22. A water outlet pipe 210 communicating with the water outlet area is installed at the bottom of the water tank 22 to transport the filtered water to the next stage, such as into the sterilization system. Both the water inlet pipe 28 and the water outlet pipe 210 extend out of the isolation box 1. The bottom of the water tank 22 is at the same height as the bottom of the second water inlet 25 to prevent water accumulation in the water tank 22 and reduce the risk of contamination.

[0036] Reference Figure 2 , Figures 4 to 7A filter assembly 3 is installed inside the support cylinder 2. The filter assembly 3 includes a support shaft 31 rotatably mounted on the isolation box 1. Several isolation plates 32 are fixedly mounted on the support shaft 31, dividing the support cylinder 2 into several filter chambers. The outer diameter of the isolation plates 32 is adapted to the inner diameter of the support cylinder 2, thereby achieving a close fit between the outer surface of the isolation plates 32 and the inner diameter of the support cylinder 2, reducing the risk of leakage. The isolation plates 32 rotate inside the support cylinder 2. Two sealing plates 33 are fixedly mounted at both ends of the support shaft 31. The sealing plates 33 rotate inside the support cylinder 2, with the end face of the sealing plate 33 at the liquid inlet end fitting against the inner surface of the end of the support cylinder 2. The filter chambers formed by the isolation plates 32 are fixedly installed with... A filter screen 34 is provided. It should be noted that one of the filter chambers does not have a filter screen 34. The filter screen 34 divides the filter chamber into a filter compartment 35 and a water outlet compartment 36. The filter compartment 35 has liquid inlet holes 37. The two liquid inlet holes 37 on the upper side are connected to the water inlet area of ​​the water tank 22 through the first water inlet hole 24, and the two liquid inlet holes 37 on the lower side are connected to the water inlet area of ​​the water tank 22 through the second water inlet hole 25. The water outlet compartment 36 has liquid outlet holes 38. The two liquid outlet holes 38 on the upper side are connected to the water outlet area of ​​the water tank 22 through the first water outlet hole 26, and the two liquid outlet holes 38 on the lower side are connected to the water outlet area of ​​the water tank 22 through the second water outlet hole 27. When the support shaft 31 drives the filter screen 34 to switch positions, because the first water inlet hole 24 and the first water outlet hole 26 adopt an arc-shaped opening design, at least one set of filter chambers 35 and water outlet chambers 36 can be in the filtering working state during the switching process. After a single position switch is completed, at least three sets of filter chambers 35 and water outlet chambers 36 are in the filtering working state, ensuring that the filter screen 34 can be cleaned without interrupting the filtering process, thereby improving the filtering and cleaning efficiency. A sealing groove is provided on the sealing plate 33, and a sealing ring 39 is installed in the sealing groove. The sealing ring 39 is used to maintain the sealing between the sealing plate 33 and the inner wall of the support cylinder 2, further reducing the risk of leakage.

[0037] Reference Figure 2 , Figures 7 to 9 The filtration device also includes a cleaning component 4, which includes a support pipe 41 rotatably connected to the isolation box 1. The support pipe 41 is rotatably connected to the support cylinder 2 and passes through the end of the support cylinder 2. A support frame 42 is fixedly installed on the support pipe 41. A brush 43 is fixedly installed on the support frame 42. An inlet groove 44 is opened on the support frame 42. Several water spray holes 45 are opened on the inlet groove 44. The water spray holes 45 are evenly distributed in the gaps between the brushes 43. A connecting pipe 46 is fixedly installed on the support pipe 41. The inside of the support pipe 41 is connected to the inlet groove 44 through the connecting pipe 46. A water sliding ring 47 is fixedly installed on the isolation box 1. The water inlet end of the support pipe 41 is connected to the water outlet end of the water sliding ring 47. The water inlet end of the water sliding ring 47 is connected to the liquid supply equipment.

[0038] The arc length of the filter screen 34 is less than half the length of the entire circle. When the filter screen 34 rotates into the cleaning hole 21, the axis of the filter screen 34 coincides with the axis of the support tube 41. When the support tube 41 drives the brush 43 to rotate, the end of the brush 43 can contact the inner wall of the filter screen 34, thereby cleaning the particles or fiber impurities such as dander and hair that are filtered and intercepted. The water spray hole 45 continuously sprays high-pressure water, which can impact the inner wall of the filter screen 34 when the brush 43 is cleaning. When the brush 43 rotates to tilt downwards, it can wash away the fiber impurities on the brush 43, ensuring that the brush 43 is in a clean state.

[0039] The filtration device also includes two geared motors 5 mounted on the isolation box 1. The output end of one geared motor 5 is fixedly connected to the support shaft 31 via a coupling, and the output end of the other geared motor 5 is fixedly connected to the support tube 41 via a coupling, thereby providing power to the support shaft 31 and the support tube 41. It should be noted that angle sensors are installed on both the support shaft 31 and the support tube 41 to determine their rotation angle. In this embodiment, there are five filter chambers. During cleaning, the support shaft 31 rotates 72 degrees each time, meaning that every 72 degrees of rotation, the positions of two adjacent filter screens 34 are interchanged.

[0040] Working principle: During filtration, the empty filter chamber is at the bottom. When control valve 29 is opened, water flows into the inlet area of ​​water tank 22 through inlet pipe 28, then through the first inlet hole 24, the second inlet hole 25, and the liquid inlet hole 37 into filter chamber 35. After being filtered by filter screen 34, water enters outlet chamber 36, then through liquid outlet hole 38, the first outlet hole 26, and the second outlet hole 27 into the outlet area of ​​water tank 22. Finally, it is transported to subsequent treatment equipment through outlet pipe 210 at the bottom. Simultaneous filtration through multiple sets of filter screens 34 greatly improves filtration efficiency.

[0041] When the filter screen 34 is cleaned periodically, the output end of the lower geared motor 5 drives the support tube 41 to rotate, and the support tube 41 drives the support frame 42 and the brush 43 to rotate, so that the head of the brush 43 faces downward. The output end of the upper geared motor 5 drives the support shaft 31, the isolation plate 32, the sealing plate 33 and the filter screen 34 to rotate, so that the filter screen 34 rotates to the position of the cleaning hole 21. At this time, the axis of the filter screen 34 in the cleaning hole 21 is collinear with the axis of the support tube 41. During the rotation of the sealing plate 33, the two liquid inlets 37 on the lower side quickly separate from the second water inlet 25, and the two liquid outlets 38 on the lower side quickly separate from the second water outlet 27. The second water inlet 25 and the second water outlet 27 are blocked by the sealing plate 33 and cannot supply or discharge liquid. At least one liquid inlet 37 on the upper side can remain connected to the first water inlet 24 during the rotation, and the corresponding liquid outlet 38 can also remain connected to the first water outlet 26 during the rotation, thus ensuring uninterrupted filtration. After the filter screen 34 completes one position switch, the liquid inlet 37 and the liquid outlet 38 in the cleaning hole 21 are blocked by the support cylinder 2, while the other liquid inlets 37 and the liquid outlet 38 are connected to the water inlet and outlet areas of the water tank 22, improving the filtration efficiency after switching and reducing the impact of cleaning on the filtration volume.

[0042] During cleaning, the liquid supply device provides pressurized water to the support pipe 41 through the water-lubricating ring 47. The pressurized water enters the liquid inlet tank 44 through the connecting pipe 46 and is quickly sprayed out from the spray nozzle 45. The output end of the reduction motor 5 drives the support pipe 41, support frame 42, and brush 43 to rotate. When the brush 43 rotates, its end can contact the surface of the filter screen 34, and in conjunction with the water spray, it impacts the filter screen 34, thereby achieving efficient cleaning of the filter screen 34. When the brush 43 detaches from the filter screen 34, the sprayed water flow can wash away the fibrous impurities on the brush 43, achieving simultaneous cleaning of impurities on the brush 43. The cleaned impurities fall into the bottom of the isolation box 1 and are discharged from the drain port opened at the bottom of the isolation box 1. Repeating the above steps can achieve cleaning of multiple filter screens 34 one by one without the need for personnel to disassemble and manually clean them, greatly improving cleaning efficiency.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
