[0025] Please refer to Figure 4 and Figure 5 The filter element assembly 20 provided in this embodiment includes a shell assembly 21, a separator 23, and a filter element 22. The shell assembly 21 has a shell opening 2112 and an internal receiving cavity 2113. At least a portion of the separator 23 is disposed within the receiving cavity 2113, dividing the shell opening 2112 into an inlet 2a and an outlet 2b. Unfiltered water enters through the inlet 2a, is filtered by the filter element 22, and is discharged from the outlet 2b.

[0026] The filter element assembly 20 is generally configured as a component of a purification or filtration device, used to purify or filter liquids to be cleaned. These liquids may include water or other liquids. The technical solution of this application is described below using water as the liquid to be cleaned. The housing assembly 21 of the filter element assembly 20 has an internal accommodating cavity 2113. The accommodating cavity 2113 is mainly used to accommodate the filter element 22 with filtration function and to define the flow direction of water, ensuring that the water is fully filtered within the filter element 22. To facilitate water flow into the accommodating cavity 2113, the housing assembly 21 has a housing opening 2112, and a separator 23 divides the housing opening 2112 into an inlet 2a and an outlet 2b. In some embodiments, the separator 23 can be disposed in the middle of the shell opening 2112, dividing the shell opening 2112 into an inlet 2a and an outlet 2b on the left and right sides. When installing the filter element assembly 20, the user only needs to install the shell opening 2112 so that the inlet 2a corresponds to the external inlet pipe and the outlet 2b corresponds to the external outlet pipe. For example, the external pipe includes an "8"-shaped pipe structure with two pipes. By connecting the inlet 2a to one pipe of this pipe structure and the outlet 2b to the other pipe of the pipe structure, the filtration function of the filter element assembly 20 can be realized. The pipe connection here can be achieved by one or more combinations of snap-fit, magnetic attraction, sleeve, etc., as long as it is convenient for the two to be connected and fixed.

[0027] In some embodiments, the filter element 22 is a ceramic membrane. Ceramic membrane filtration is a physical sieving process that utilizes a porous ceramic material as a barrier to allow water molecules to pass through while completely trapping suspended solids, bacteria, algae, and other impurities in the water, thereby achieving high-precision purification far exceeding traditional filtration methods. Multiple filter elements 22 can be arranged evenly within the receiving cavity 2113. In some embodiments, the filter elements 22 are elongated. To facilitate water flow within the filter elements 22 and achieve filtration, the inlet side of the filter element 22 can be positioned corresponding to the inlet 2a. In some embodiments, at least a portion of the cavity wall or other structures (e.g., partitions or a combination of partitions and cavity walls) of the receiving cavity 2113 can surround a portion of the filter element, increasing the flow length of water within the filter element 22 and resulting in superior filtration performance.

[0028] As an example, both the inlet 2a and the outlet 2b are located in the same direction of the filter element assembly 20. For instance, if the shell assembly 21 is elongated, then the inlet 2a and the outlet 2b are located on the same side of the axial direction of the shell assembly 21. Furthermore, the inlet 2a and the outlet 2b are located at one end of the axial direction of the shell assembly 21. This arrangement improves the integration of the inlet 2a and the outlet 2b, simplifying the structure of the filter element assembly 20. In some embodiments, the number of inlet 2a and outlet 2b is set to one. Compared to the traditional filter element assembly 20 with at least two inlets 2a and two outlets 2b, the filter element assembly 20 with multiple interfaces is not only more complex in assembly but also has a more complex flow path structure, increasing the difficulty of controlling the flow rate at the interfaces. The filter element assembly 20 in this embodiment only requires the installation of the shell opening 2112, controlling fewer interfaces. This arrangement not only simplifies the assembly process and the flow path structure of the filter element assembly 20 but also improves the accuracy of flow rate control and enhances the user experience.

[0029] Please refer to Figure 3 and Figure 12 This application embodiment also provides a mounting base 1 for installing a filter element assembly 20. The mounting base 1 includes a base body 10, which has at least one mounting structure 13, at least one first channel 11, and at least one second channel 12. At least one end opening of the first channel 11 and at least one end opening of the second channel 12 are both located in the mounting structure 13. The filter element assembly 20 is detachably connected to the mounting structure 13, such that the inlet 2a communicates with the first channel 11, and the outlet 2b communicates with the second channel 12. Unfiltered water is filtered by the filter element assembly 20 through the first channel 11 and flows out through the second channel 12.

[0030] By setting a first channel 11 and a second channel 12 (one of which is used for water inlet and the other for water outlet) in the mounting base, and integrating the end openings of the first channel 11 and the second channel 12 into the mounting structure 13 of the mounting base 1, when the filter element assembly 20 is installed in the mounting base 1, the water inlet 2a and the water outlet 2b of the filter element assembly 20 can be fixed by a mounting structure 13, so that the first channel 11 is connected to the water inlet 2a and the second channel 12 is connected to the water outlet 2b. Unfiltered water enters through the first channel 11, enters the filter element assembly 20 through the water inlet 2a, is filtered, flows into the second channel 12 through the water outlet 2b, and is discharged from the mounting base 1.

[0031] In this embodiment, the filter element assembly 20 is installed by snapping it into the mounting structure 13 of the mounting base 1. Specifically, the filter element assembly 20 can be installed simply by aligning it with the mounting structure 13 and rotating it. Similarly, disassembly of the filter element assembly 20 is also achieved by simply rotating it, making the operation convenient. Furthermore, the flow path structure within the mounting base 1 is simple, improving filtration efficiency. In some embodiments, after aligning the filter element assembly 20 with the mounting structure 13, the filter element assembly 20 can be installed on the mounting base using an auxiliary mounting structure adjacent to the mounting structure. This auxiliary mounting structure can be a component independent of the mounting structure and may include, for example, a snap-fit ​​structure, a keyway fixing structure, or a sleeve fixing structure. Moreover, the internal structure design of the filter element assembly 20 and the mounting base 1 in this embodiment is compact, significantly reducing the space occupied by the mounting base 1 and the filter element assembly 20, thereby improving the applicability of the filtration device 100.

[0032] Please refer to Figures 1 to 3 This application embodiment also provides a filtration device 100, which may include the aforementioned mounting base 1 and at least one aforementioned filter element assembly 20. The filter element assembly 20 is detachably connected to the mounting base 1 and can distribute the flow water in the mounting base 1 to each filter element assembly 20 for filtration. Of course, the clean water filtered in each filter element assembly 20 is collected back into the mounting base 1, which not only reduces the volume of each individual filter element assembly 20, but also improves the convenience of replacing each filter element assembly 20.

[0033] In an optional embodiment, the filter device 100 further includes a housing 50, which has limiting through holes 52 corresponding to the number of filter element assemblies 20. The filter element assemblies 20 are adapted to the shape of the limiting through holes 52 and are installed within the limiting through holes 52 to limit their position within the housing 50. Further, the housing 50 has a plurality of retaining posts 51, and the mounting base 1 has a plurality of insertion holes 14 adapted to the retaining posts 51. The retaining posts 51 are inserted into the insertion holes 14 to limit the relative position between the housing 50 and the mounting base 1, and further improve the connection stability between the filter element assemblies 20 and the mounting base 1.

[0034] In one alternative embodiment, please refer to Figure 2 and Figure 3The filter device 100 also includes a connecting structure 40, through which the filter element assembly 20 is connected to or detached from the mounting base 1. The first connector 2111 and the second connector 133 are mutually detachable and adaptable structures achieved by magnetic attraction, threaded connection, or sleeve fixing. For example, one of the first connector 2111 and the second connector 133 may be configured as a magnet, bolt, or socket hole, while the other may be configured as iron, nut, or sleeve.

[0035] Specifically, the filter element assembly 20 is provided with a first connector 2111 at one end near the mounting base 1. The mounting base 1 is provided with a mounting structure 13, which is a mounting hole 131. The inner wall of the mounting hole 131 is provided with a second connector 133 that is adapted to the first connector 2111. The connection structure 40 may include the first connector 2111 and the second connector 133.

[0036] The specific structures of the first connector 2111 and the second connector 133 are not limited in the embodiments of this application. For example, the first connector 2111 and the second connector 133 can be mutually adaptable protruding structures. In some examples, when installing the filter element assembly 20 onto the mounting base 1, the first connector 2111 and the second connector 133 are aligned and the filter element assembly 20 is rotated so that the first connector and the second connector engage or lock with each other, thereby installing the filter element assembly 20 onto the mounting base 1. When it is necessary to remove the filter element assembly 20 from the mounting base 1, the filter element assembly 20 is rotated in the opposite direction so that the first connector and the second connector disengage or release from each other, thereby removing the filter element assembly 20.

[0037] The embodiments of this application utilize the connection structure 40 to quickly and easily install and disassemble the filter element assembly 20, improving the maintenance convenience of the filter element assembly 20 and enabling it to adapt to filtration systems for swimming pools of different sizes.

[0038] The following embodiments provide a detailed description of the filter element assembly 20. Please refer to [link / reference]. Figures 1 to 11 .

[0039] In an optional embodiment, the separator 23 is provided with a mounting position 232 for mounting the filter element 22. Please refer to... Figure 5 One end of the filter element 22 is connected to the separator 23, thereby allowing the separator 23 to limit the position of the filter element 22 within the receiving cavity 2113 and ensure filtration stability.

[0040] The filter element assembly 20 consists of multiple independent filter elements 22. Each filter element 22 has multiple filter holes extending along its axis, which is also the axis of the housing assembly 21. This means that the axes of the filter elements 22, the separator 23, and the housing assembly 21 are all parallel to each other, allowing unfiltered water to enter through the end openings of the filter holes in the filter elements 22, thus ensuring filtration efficiency and effectiveness.

[0041] In one alternative embodiment, please refer to Figure 5 and Figure 6 The separator 23 includes a first limiting seat 24 adapted to multiple independent filter elements 22. The first limiting seat 24 can be connected to the separator 23 in different ways, or it can be integrally formed with the separator 23. In this embodiment, the connection method between the first limiting seat 24 and the separator 23 is not limited. The first limiting seat 24 is provided with multiple first through holes 241, which are adapted to the independent filter elements 22. The filter elements 22 are inserted into the first through holes 241. The first limiting seat 24 not only restricts the position of the filter elements 22 in the receiving cavity 2113, but also allows a certain space to be formed between adjacent filter elements 22 so that the filtered water can be discharged.

[0042] In an optional embodiment, the separator 23 includes a cylindrical separator 233 and a mounting portion 234 connected to the cylindrical separator 233. A mounting position 232 is provided on the mounting portion 234. The cylindrical separator 233 divides the shell opening 2112 into an inlet 2a and an outlet 2b. One of the inlet 2a and the outlet 2b is arranged around the other.

[0043] Figure 5 The arrows in the figure indicate the direction of water flow. As shown, the outlet 2b surrounds the inlet 2a. Unfiltered water enters through the inlet 2a, flows through multiple filter elements 22, and is discharged from the outlet 2b. It can be understood that when the inlet 2a and outlet 2b are arranged in a way that surrounds each other, the corresponding water flow system can also be arranged in this manner. For example, the mounting base 1 for installing the filter element assembly 20 includes a base body 10. The base body 10 is provided with at least one mounting structure 13, at least one first channel 11, and at least one second channel 12. At least one end opening of the first channel 11 and at least one end opening of the second channel 12 are both located on the mounting structure 13. One of the two end openings is arranged around the other, thereby facilitating the installation of the filter element assembly 20 and the flow of water.

[0044] When backflushing the flow channel, the water or chemical solution used for flushing flows from... Figure 5The water flows through multiple filter elements 22 and then exits through the inlet 2a at the outlet 2b shown in the figure, so as to wash away the dirt and impurities attached to the surface of the multiple filter elements 22.

[0045] In one alternative embodiment, please refer to Figure 3 and Figure 5 The cylindrical partition 233 extends out of the shell opening 2112 at the end away from the mounting part 234.

[0046] The portion of the cylindrical partition 233 extending out of the shell opening 2112 is used to connect to one of the first channel 11 and the second channel 12 provided on the mounting base 1. Specifically, the connection method can be that the portion of the cylindrical partition 233 extending out of the shell opening 2112 is sleeved on the first channel 11 or the second channel 22, or sleeved on the partition structure between the two. For example, the first channel 11 and the second channel 12 are isolated by a partition plate, so that the inlet 2a or outlet 2b formed between the shell opening 2112 of the shell assembly 21 and the cylindrical partition 233 is used to connect to the other of the first channel 11 and the second channel 12 provided on the mounting base 1. This enables both unfiltered water and filtered water to enter and exit from the same end of the filter element assembly 20, thereby improving the structural compactness of the filter element assembly.

[0047] In one alternative embodiment, please refer to Figure 3 , Figure 5 and Figure 6 The shell assembly 21 includes a shell body 211 and an end cap 212, the end cap 212 being sealed and detachably connected to the end of the shell body 211 away from the shell opening 2112.

[0048] The end cap 212 has external threads on its outer surface, and the inner wall of the shell body 211 has internal threads that are compatible with the external threads. The end cap 212 and the shell body 211 are detachably connected through the external and internal threads. Of course, the connection method between the end cap 212 and the shell body is not limited to this.

[0049] The filter element assembly 20 also includes a fourth sealing element 29, which is a sealing ring. The fourth sealing element 29 is connected between the end cap 212 and the housing body to achieve a sealed connection between the end cap 212 and the housing body, preventing the circulating water in the accommodating cavity 2113 from overflowing and ensuring the filtration effect of the filter element assembly 20. The number of fourth sealing elements 29 can be set according to the volume of the housing body 211, and this application embodiment does not make a specific limitation.

[0050] In an alternative embodiment, the separator 23 and the housing assembly 21 together form a mounting position 232 for mounting the filter element 22.

[0051] This can be understood as follows: one end of the filter element 22 is connected to the separator 23, and the other end is connected to the housing assembly 21; or, one degree of freedom of the filter element 22 is limited by the separator 23, and the other degree of freedom is limited by the housing assembly 21. The housing assembly 21 also includes a second limiting seat 25, which has the same structure as the first limiting seat 24. The second limiting seat 25 can be connected to the end cap 212 of the housing assembly 21 through different connection methods and can be integrally formed with the end cap 212. The second limiting seat 25 is provided with multiple second through holes 251, which are adapted to the filter element 22. One end of the filter element 22 is inserted into the first through hole 241, and the other end is inserted into the second through hole 251. By distributing and fixing the two ends of the filter element 22 with the first limiting seat 24 and the second limiting seat 25 respectively, the impact of water flow on the filter element 22 can be resisted, further ensuring the connection stability of the filter element 22 during the filtration process and ensuring the filtration effect.

[0052] Furthermore, the filter element assembly 20 also includes a first sealing element 26, which is a sealing ring. The first sealing element 26 is connected between the second limiting seat 25 and the end cap 212 to achieve the sealing of the filter hole of the filter element 22 and the receiving cavity 2113, so as to prevent unfiltered water in the filter element 22 from flowing directly into the receiving cavity 2113 and ensure the filtration effect.

[0053] In an alternative embodiment, the mounting portion 234 includes a first direction (i.e., Figure 5 The mounting cylinder 2341 extends in the direction of arrow s1 shown in the figure. The mounting cylinder 2341 and the inner wall of the shell body form a water outlet channel 2c. The clean water obtained after being filtered by multiple filter elements 22 flows from the water outlet channel 2c to the water outlet 2b. The first direction is the axial direction of the shell body.

[0054] The mounting cylinder 2341 extends from the cylindrical partition 233 in the first direction toward the end cap 212. The mounting cylinder 2341 and the filter element 22, as well as the mounting cylinder 2341 and the inner wall of the shell body 211, form a water outlet channel 2c. The water outlet channel 2c can guide the filtered clean water, which can greatly reduce the turbulence of the filtered clean water and improve the stability and filtration efficiency of the clean water discharge.

[0055] In one alternative embodiment, please refer to Figure 5 The end of the mounting cylinder 2341 is spaced apart from the end cap 212.

[0056] It can be understood that the mounting cylinder 2341 extends from the cylindrical partition 233 along the first direction toward the end cover 212 to a certain distance from the end cover 212. The size of this distance can be set according to specific circumstances, and this application embodiment does not make specific limitations.

[0057] like Figure 5 As shown, the clean water discharged after filtration by the filter element 22 corresponding to the mounting cylinder 2341 and the end cap 212 flows directly to the water outlet channel 2c formed between the mounting cylinder 2341 and the inner wall of the shell body 211. Meanwhile, the clean water discharged after filtration by the filter element 22 at the corresponding position of the mounting cylinder 2341 first exits through the water outlet channel 2c formed between the mounting cylinder 2341 and the filter element 22, and then exits through the water outlet channel 2c formed between the mounting cylinder 2341 and the inner wall of the shell body 211.

[0058] Since the mounting cylinder 2341 is close to the outlet 2b, the water flow channel 2c between the mounting cylinder 2341 and the filter element 22 can buffer the filtered clean water, which can prevent a large amount of filtered clean water from accumulating at the outlet 2b and forming turbulence, thereby improving the stability and uniformity of the clean water discharge and further improving the filtration efficiency and filtration effect of the filter element assembly 20.

[0059] In one alternative embodiment, please refer to Figure 7 The cylinder wall of the mounting cylinder 2341 is provided with multiple water-permeable holes 2342. Figure 7 The diagram shows that clean water filtered by filter element 22 can flow into water outlet channel 2c through multiple water permeable holes 2342, and clean water filtered by filter element 22 located between mounting cylinder 2341 and end cap 212 can flow directly to water outlet channel 2c.

[0060] This can be understood as follows: the clean water discharged after being filtered by the filter element 22 at the corresponding position of the mounting cylinder 2341 can flow through the water permeable hole 2342 to the water outlet channel 2c between the mounting cylinder 2341 and the shell body 211. The multiple water permeable holes 2342 can also buffer the discharged clean water.

[0061] In this embodiment, the mounting cylinder 2341 may be at a certain distance from the end cap 212, or the mounting cylinder 2341 may extend to the end cap 212. The number, size, and distribution of the water-permeable holes 2342 on the mounting cylinder 2341 are not specifically limited in this embodiment, and can be set according to specific circumstances, with the principle that the filtered clean water can be discharged smoothly and evenly from the outlet 2b.

[0062] In one alternative embodiment, please refer to Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11 Multiple diversion plates 231 are provided on the outside of the separator 23. The multiple diversion plates 231 are distributed circumferentially around the axis of the separator 23. The multiple diversion plates 231 divide the water outlet channel 2c into multiple water outlet sub-channels 2c1.

[0063] like Figure 9As shown, the end of the diversion plate 231 is in contact with the inner wall of the shell body 211. The clean water filtered by the filter element is diverted by multiple diversion plates 231 and discharged from the outlet 2b. Under the action of multiple diversion plates 231, the filtered clean water can greatly reduce the local aggregation phenomenon, thereby improving the uniformity and stability of the discharged clean water.

[0064] In one alternative embodiment, the separator 23 is detachably connected to the housing body 211. The separator 23 can be connected to the housing body 211 by the ends of multiple diverter plates 231 abutting against the inner wall of the housing body 211, but this is not the only possible connection. The detachable connection between the separator 23 and the housing body 211 improves the convenience of assembling and maintaining the filter element 22.

[0065] In an alternative embodiment, the shell assembly 21 is provided with a first connecting portion 213, which is configured to enable the shell body to have a detachable connection function.

[0066] In this embodiment, the first connecting portion 213 extends from the end of the shell body 211 away from the end cap 212 and is used for detachable connection with the mounting base 1. One or more first connecting members 2111 are provided on the outer wall of the first connecting portion 213. These first connecting members 2111 are circumferentially distributed around the axis of the shell body 211. Each first connecting member 2111 is a protrusion protruding from the outer wall of the first connecting portion 213, and the second connecting member 133 is a protrusion adapted to the first connecting member 2111, but is not limited to these. The first connecting member 2111 and the second connecting member 133 are engaged or disengaged by rotating the filter element assembly 20.

[0067] In one alternative embodiment, please refer to Figure 3 When the filter element assembly 20 is installed on the mounting base 1, the portion of the mounting part 234 extending out of the shell opening 2112 is sealed to the mounting base 1 via a third sealing member 28. Similarly, the end of the shell body 211 is sealed to the mounting base 1 via a second sealing member 27. The number of second sealing members 27 and third sealing members 28 can be set according to requirements, and this embodiment does not limit the number of sealing members. The first sealing member 26 and the second sealing member 27 are sealing rings, but are not limited to this.

[0068] The following embodiment provides a detailed description of the mounting base 1.

[0069] In one optional embodiment, there are multiple mounting structures 13, and multiple first channels 11 and second channels 12. Each mounting structure 13 is connected to the end opening of a first channel 11 and a second channel 12.

[0070] The number of mounting structures 13 can be set according to the size of the mounting base 1, for example: two, three, four, five. This application embodiment does not impose a specific limitation.

[0071] In one alternative embodiment, please refer to Figure 3 , Figure 12 , Figure 13 and Figure 14 The seat body 10 also includes a third channel 15 and a fourth channel 16. The third channel 15 is connected to the end of the first channel 11 away from the mounting structure 13, and the fourth channel 16 is connected to the end of the second channel 12 away from the mounting structure 13. The third channel 15 is provided with at least one first water flow opening in the axial and / or radial direction, and the fourth channel 16 is provided with at least one second water flow opening in the axial and / or radial direction. The first water flow opening and the second water flow opening are used for water flow.

[0072] This can be understood as follows: one end of the first channel 11 is connected to the inlet 2a, and the other end is connected to the third channel 15. One end of the second channel 12 is connected to the outlet 2b, and the other end is connected to the fourth channel 16. Multiple first channels 11 are all connected to the third channel 15, and multiple second channels 12 are all connected to the fourth channel 16. Both the third channel 15 and the fourth channel 16 extend along an axis perpendicular to the first channel 11.

[0073] In this embodiment, unfiltered water entering from the third channel 15 is dispersed into multiple first channels 11 as it flows through the third channel 15. The clean water filtered by the filter element assembly 20 is then collected into the fourth channel 16 by multiple second channels 12. By using multiple mounting structures 13, first channels 11, and second channels 12 provided in the mounting base 1 to divert the water to be filtered and filter it separately using multiple filter element assemblies 20, the filtration efficiency can be greatly improved, and the stability and filtration quality of the filtration device 100 can be guaranteed.

[0074] In an optional embodiment, there are multiple first water flow openings and multiple second water flow openings, and the mounting base 1 also includes at least one valve (not shown in the figure) for opening or closing the first water flow opening and the second water flow opening.

[0075] Specifically, the first water flow opening and the second water flow opening are respectively the water inlet opening 31 and the water outlet opening 32, and the water inlet opening 31 and the water outlet opening 32 are respectively connected to the third channel 15 and the fourth channel 16.

[0076] Please refer to Figure 15 , Figure 15The diagram shows unfiltered water entering the third channel 15 through the inlet opening 31. The unfiltered water in the third channel 15 flows into multiple filter cartridges 20. The clean water filtered by the filter cartridges 20 converges into the fourth channel 16 and is discharged through the outlet opening 32.

[0077] In one specific embodiment, please refer to Figure 1 , Figure 2 and Figure 16 The first water flow opening and the second water flow opening are respectively the first cleaning opening 33 and the second cleaning opening 34. The first cleaning opening 33 and the second cleaning opening 34 are respectively connected to the third channel 15 and the fourth channel 16. The first cleaning opening 33 is configured to input cleaning fluid into the fourth channel 16. The first cleaning opening 33, the fourth channel 16, the filter element assembly 20, the third channel 15 and the second cleaning opening 34 form a closed loop.

[0078] This application embodiment is used to perform backwashing operation on multiple filter element components 20. The cleaning solution can be clean water or cleaning solution, so as to achieve thorough cleaning by penetrating the membrane pores with the cleaning solution, which can greatly reduce the impact of organic matter and colloids on membrane pores and affect filtration efficiency.

[0079] Furthermore, the mounting base 1 is also provided with a third cleaning opening 35, which is connected to the fourth channel 16 and is configured to communicate with the second cleaning opening 34.

[0080] In this embodiment, the cleaning fluid enters the fourth channel 16 through the first cleaning opening 33, flows through the filter element assembly 20, and exits through the second cleaning opening 34, which communicates with the third channel 15. The carried-out dirt is discharged through the drain port 36 provided on the mounting base 1. A connecting pipe connects the second cleaning opening 34 and the third cleaning opening 35, allowing the liquid discharged from the second cleaning opening 34 to re-enter the fourth channel 16 through the third cleaning opening 35, thus achieving a closed loop. This enables multiple cycles of cleaning the filter element assembly 20, ensuring effective cleaning of the filter element 22 within the filter element assembly 20.

[0081] Figure 16 The diagram shows that the cleaning fluid enters the fourth channel 16 through the first cleaning opening 33, then flows through multiple filter elements 20 and then flows from the second cleaning opening 34 to the third cleaning opening 35, and then flows back into the fourth channel 16. At the same time, the dirt carried out by the liquid is discharged through the drain port 36.

[0082] In an optional embodiment, the fourth channel 16 is further provided with a first drug port 37 and a second drug port 38 for inputting different types of drugs into the fourth channel 16. The specific type of drug is not specifically limited in this embodiment and can be selected according to needs.

[0083] In one alternative embodiment, please refer to Figure 3 and Figure 12 The mounting structure 13 is a mounting hole 131, which is a stepped hole 132. The small diameter section 1321 of the stepped hole 132 is connected to the first channel 11, and the large diameter section 1322 of the stepped hole 132 is connected to the second channel 12.

[0084] In this embodiment of the application, when the filter element assembly 20 is installed in the mounting hole 131 of the mounting base 1, the end of the separator 2331 is sealed to the inner wall of the small aperture section 1321, and the end of the shell body 211, that is, the first connecting part 213, is sealed to the inside of the large aperture section 1322, so that the small aperture section 1321 is connected to the inlet 2a and the large aperture section 1322 is connected to the outlet 2b.

[0085] In this embodiment, the axes of the small aperture section 1321 and the large aperture section 1322 are collinear with the axis of the shell body 211, which can greatly reduce the resistance during water flow and improve filtration efficiency.

[0086] In this embodiment, the large-aperture section 1322 surrounds the small-aperture section 1321 near the end of the filter element assembly 20, thereby improving the compactness of the mounting structure 13 and thus improving the structural compactness of the mounting base 1 and reducing the space occupied.

[0087] In one alternative embodiment, please refer to Figure 3 and Figure 12 The small pore section 1321 also includes a baffle 1323 extending toward the large pore section 1322, the baffle 1323 being used to connect to the filter element assembly 20 and to separate the first channel 11 and the second channel 12.

[0088] In this embodiment, the baffle 1323 extends from the small-diameter section 1321 to the end of the first connecting portion 213 near the shell body 211. It can be understood that there is a distance between the end of the baffle 1323 and the end of the first connecting portion 213, so that clean water discharged from the outlet 2b can flow from between the baffle 1323 and the first connecting portion 213 to the second channel 12.

[0089] Furthermore, the greater the distance between the end of the baffle 1323 and the end of the first connecting part 213, the better, so that the clean water discharged from the outlet 2b can flow more smoothly into the second channel 12. It can be understood that the baffle 1323 formed by extending from the small-diameter section 1321 only needs to be able to connect to the separator cylinder 2331.

[0090] Specifically, the first connecting part 213 of the shell body 211 is sealed to the inner wall of the large-diameter section 1322 through the second sealing element 27. The partition cylinder 2331 and the baffle 1323 are sealed to each other through the third sealing element 28.

[0091] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
