Description

Technical Field

[0001] This utility model relates to the field of water purification and filtration technology, and in particular to a water purification and filtration structure. Background Technology

[0002] The concept of water filtration is defined based on the primary and secondary roles of water. When water is the primary element, water filtration is a medium used to filter and treat other impurities; it's a filtration method that effectively separates solids and gases through water dissolution. When water is the secondary element, water filtration is a method specifically designed to treat water; it uses a filter medium to remove suspended solids from the water, thereby obtaining clean water. Filters are indispensable devices in pipelines transporting media, typically installed at the inlet end of pressure reducing valves, pressure relief valves, level control valves, and other equipment. A filter consists of a cylinder, stainless steel filter screen, a drain section, a transmission device, and an electrical control system. After the water to be treated passes through the filter cylinder, impurities are blocked. When cleaning is required, simply remove the detachable filter cylinder, clean it, and reinstall it; therefore, use and maintenance are extremely convenient.

[0003] For example, patent (CN 222274164 U) discloses a water purification filter structure. A limiting plate is fixedly connected to the outer surface of the water purification shell. Telescopic columns are fixedly connected to both ends of the outer surface of the limiting plate. Limiting rings are fixedly connected to the outer surfaces of the telescopic columns. Support plates are fixedly connected to both ends of the limiting rings. A connecting plate is fixedly connected to one end of the support plate, and a rotating shaft is fixedly connected to one end of the connecting plate. A rotating ring is rotatably connected to the outer surface of the rotating shaft. This utility model, through the arrangement of the water purification shell, the slots, and the filter shell, allows for easy use. During use, tweezers are used to grip the slots fixed at both ends of the filter shell, pushing the filter shell through the inner surface of the water purification shell and pressing it to the designated position for fixation. After use, the filter shell can be removed for cleaning using tweezers gripping the slots fixed at both ends of the filter shell. This achieves the effect of assembling and cleaning the filter layer according to needs.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: the shell structure design of traditional water purifiers is inconvenient to disassemble, making it difficult for users to quickly clean and replace the internal filter plates. During long-term use, the filter plates continuously trap suspended particles, colloids, and other impurities in the water. These contaminants gradually accumulate on the surface of the filter plates, eventually forming a dense layer of dirt. As the filtration time increases, this clogging will intensify, significantly reducing water purification efficiency and water flow rate, and causing premature filter plate failure, seriously affecting the normal performance of the water purifier. Furthermore, filter plate clogging may also lead to secondary pollution risks, as accumulated contaminants may become a breeding ground for microorganisms, further affecting the quality of the output water. Therefore, we designed a water purification filtration structure to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A water purification filtration structure includes a lower outer shell, an upper outer shell rotatably connected to one side of the top tube of the lower outer shell, PP cotton, activated carbon, an RO membrane and post-carbon filter fixed between the upper and lower outer shells, a sealing plate fixed to one side of the top of the lower outer shell, a sealing groove formed on one side of the bottom of the upper outer shell, the outer side of the sealing plate slidably connected to the sealing groove, a sealing block fixed to the other side of the top of the lower outer shell, and a sealing gasket fixed to the other side of the bottom of the upper outer shell, the inner side of the sealing gasket slidably connected to the sealing block.

[0007] In a preferred embodiment of the water purification and filtration structure provided by this utility model, a support plate is fixed to the bottom of the lower outer shell, and the four ends of the support plate are threadedly connected to the wall by bolts.

[0008] As a preferred embodiment of the water purification filtration structure provided by this utility model, a disassembly mechanism for quickly replacing and cleaning the PP cotton, activated carbon, RO membrane and post-carbon filter is provided on the other side of the upper and lower outer shells. The disassembly mechanism includes a handwheel, a linkage chain and a locking block. Locking blocks are fixed at both ends of the other side of the upper outer shell, and a handwheel is rotatably connected to both ends of the other side of the lower outer shell. A linkage chain is rotatably connected to the outer side of the handwheel, and the end of the linkage chain away from the handwheel is engaged with the locking block.

[0009] In a preferred embodiment of the water purification and filtration structure provided by this utility model, the connection between the handwheel and the linkage chain is offset from the center of the handwheel.

[0010] In a preferred embodiment of the water purification and filtration structure provided by this utility model, limit rods are fixed at both ends on the other side of the lower outer shell. A limit block is rotatably connected to the end of the limit rod away from the upper outer shell. A rectangular groove is provided inside the handwheel. One end of the limit block is rotatably connected to the handwheel through the rectangular groove.

[0011] As a preferred embodiment of the water purification filtration structure provided by this utility model, a plurality of retaining rings are fixed on the inner sides of both the upper and lower outer shells, and the plurality of retaining rings are respectively engaged with the RO membrane, activated carbon, PP cotton and post-carbon filter.

[0012] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0013] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0014] This utility model provides a water purification filtration structure that uses a linkage chain to engage with a locking block. By rotating a handwheel, the linkage chain is pulled, causing the upper outer shell to drive the sealing gasket to seal the sealing block and the lower outer shell. The sealing plate is then sealed to the sealing groove, thereby effectively improving the sealing effect between the upper and lower outer shells. This also allows for the quick replacement and assembly of PP cotton, activated carbon, RO membrane, and post-carbon filter, ensuring the filtration effect of the device.

[0015] When the handwheel is turned to drive the linkage chain and the upper and lower outer shells to form a sealed connection, the limiting rod and the limiting block pass through the handwheel, and the rotation of the limiting block effectively limits the handwheel, thereby effectively improving the stability of the seal between the upper and lower outer shells.

[0026] Example 1

[0027] Please refer to Figures 1-4 A water purification filtration structure includes a lower outer shell 2, an upper outer shell 1 rotatably connected to one side of the top tube of the lower outer shell 2, a support plate 3 fixed to the bottom of the lower outer shell 2, and four ends of the support plate 3 threadedly connected to the wall by bolts. PP cotton 4, activated carbon 5, RO membrane 6 and post-carbon filter 7 are fixed between the upper outer shell 1 and the lower outer shell 2. A sealing plate 13 is fixed to one side of the top of the lower outer shell 2, and a sealing groove 14 is opened on one side of the bottom of the upper outer shell 1. The outer side of the sealing plate 13 is slidably connected to the sealing groove 14. A sealing block 15 is fixed to the other side of the top of the lower outer shell 2, and a sealing gasket 16 is fixed to the other side of the bottom of the upper outer shell 1. The inner side of the sealing gasket 16 is slidably connected to the sealing block 15.

[0028] When in use, the upper outer shell 1 and the lower outer shell 2 are connected to an external water source, thereby filtering the external water source through PP cotton 4, activated carbon 5, RO membrane 6 and post-carbon filter 7, thus effectively performing deep filtration of the external water source. However, prolonged filtration will cause a large amount of particles and dust to accumulate on the surface of PP cotton 4, activated carbon 5, RO membrane 6 and post-carbon filter 7, which may lead to the risk of secondary pollution, as the accumulated pollutants may become a breeding ground for microorganisms. Therefore, the upper outer shell 1 and the lower outer shell 2 need to be disassembled regularly to effectively replace and clean PP cotton 4, activated carbon 5, RO membrane 6 and post-carbon filter 7 regularly, thereby maintaining the filtration effect of the device.

[0029] On the other side of the upper outer shell 1 and the lower outer shell 2, a disassembly mechanism is provided for quick replacement and cleaning of PP cotton 4, activated carbon 5, RO membrane 6 and post-carbon 7. The disassembly mechanism includes a handwheel 8, a linkage chain 9 and a locking block 17. The locking blocks 17 are fixed at both ends of the other side of the upper outer shell 1, and the handwheel 8 is rotatably connected to both ends of the other side of the lower outer shell 2. The linkage chain 9 is rotatably connected to the outer side of the handwheel 8. The end of the linkage chain 9 away from the handwheel 8 is engaged with the locking block 17. The connection between the handwheel 8 and the linkage chain 9 is off-center from the center of the handwheel 8.

[0030] Specifically, the linkage chain 9 is engaged with the locking block 17, and the handwheel 8 is rotated to pull the linkage chain 9 so that the upper outer shell 1 drives the sealing gasket 16 to seal the sealing block 15 and the lower outer shell 2. The sealing plate 13 is sealed to the sealing groove 14, thereby effectively improving the sealing effect between the upper outer shell 1 and the lower outer shell 2 and preventing water leakage between the upper outer shell 1 and the lower outer shell 2.

[0031] Limiting rods 11 are fixed at both ends on the other side of the lower outer shell 2. The end of the limiting rod 11 away from the upper outer shell 1 is rotatably connected to a limiting block 12. A rectangular groove 10 is provided inside the handwheel 8. One end of the limiting block 12 passes through the rectangular groove 10 and is rotatably connected to the handwheel 8.

[0032] Furthermore, when the handwheel 8 is rotated to drive the linkage chain 9 and the upper outer shell 1 to form a sealed connection with the lower outer shell 2, the limiting rod 11 and the limiting block 12 pass through the handwheel 8, and the rotation of the limiting block 12 effectively limits the handwheel 8, thereby effectively improving the stability of the seal between the upper outer shell 1 and the lower outer shell 2.

[0033] The inner sides of both the upper outer shell 1 and the lower outer shell 2 are fixed with several retaining rings. These retaining rings are respectively engaged with the RO membrane 6, activated carbon 5, PP cotton 4 and post-carbon 7, thereby effectively positioning the PP cotton 4, activated carbon 5, RO membrane 6 and post-carbon 7.

[0034] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
