[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] With the advancement of technology, people have developed diverse needs for domestic water. Water purifiers can filter the water entering the system and then output the filtered water, providing users with water that meets their needs and greatly facilitating their lives. A water purifier generally consists of interconnected filter cartridges and a main body. The main body receives unfiltered water from the filter cartridges and then supplies the filtered water to the user. After a period of filtration, the filtration efficiency of the filter components gradually decreases. To maintain stable water quality in the purifier's output, the filter cartridges are usually configured as removable consumables. In actual use, the water entering the filter cartridges from the main body typically has a certain water pressure, which tests the secure connection between the filter cartridges and the main body.

[0035] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 7 , Figure 1 This is a schematic diagram of the assembly structure of an embodiment of the water treatment equipment of this application. Figure 2 yes Figure 1 A magnified structural diagram of region A in the middle. Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section CC. Figure 4 yes Figure 3 A magnified structural diagram of region B in the middle. Figure 7 This is a schematic diagram of the assembly structure of another embodiment of the water treatment equipment of this application.

[0037] This application provides a filter cartridge device 1, including a filter assembly 2 and a sleeve 3. The filter assembly 2 has a filter interface 21 on its side that can be plugged into the device interface 511 of a water treatment device 5. The sleeve 3 is fixedly connected to the filter assembly 2 and can be sleeved by the sleeve cover 52 of the water treatment device 5 to prevent the filter interface 21 from becoming loose from the device interface 511.

[0038] In the structure provided in this specific embodiment, the sleeve 3 and the sleeve cover 52 of the water treatment equipment 5 are fitted together to form a fixed structure independent of the filter interface 21 and the equipment interface 511. When the water treatment equipment 5 operates and generates vibration or water pressure, the sleeve 3, under the mechanical limiting action of the sleeve cover 52, can significantly reduce the relative shaking between the filter interface 21 and the equipment interface 511, avoiding problems such as easy loosening and leakage caused by relying solely on the insertion and fixing of the filter interface 21 and the equipment interface 511. The fitting relationship between the sleeve 3 and the sleeve cover 52 can effectively disperse the stress at the filter interface 21 and the equipment interface 511, reducing the pressure borne by the filter interface 21 and the equipment interface 511, thereby reducing the probability of damage to the filter interface 21 and the equipment interface 511 under stress, and improving the stability and reliability of the connection between the filter element device 1 and the water treatment equipment 5.

[0039] like Figure 3 , Figure 5 , Figure 6 As shown, Figure 5 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section DD. Figure 6 yes Figure 1 The diagram shows a cross-sectional view of section EE. The filter interface 21 may include a water inlet 211 and a purified water outlet 212, and the device interface 511 may include a water inlet 511a and a purified water outlet 511b. The filter media 22 within the filter assembly 2 may have a water inlet end 221 and a purified water outlet end 222. The filter assembly 2 forms a filter element water inlet passage 23 and a filter element purified water outlet passage 24. The water inlet end 221 is connected to the water inlet interface 211 via the filter element water inlet passage 23, and the purified water outlet end 222 is connected to the purified water outlet interface 212 via the filter element purified water outlet passage 24.

[0040] Further, see Figure 8 , Figure 9 , Figure 10 , Figure 8 yes Figure 7 A schematic diagram of the cross-sectional structure shown in section FF. Figure 9 yes Figure 8 A schematic diagram of the cross-sectional structure shown in the figure. Figure 10 yes Figure 8 The cross-sectional view shown in section HH is a schematic diagram. The filter interface 21 may also include a concentrate outlet interface 213, and the device interface 511 may also include a concentrate outlet 511c. The filter media 22 in the filter assembly 2 may have a concentrate outlet end 223. A concentrate outlet path 25 is also formed in the filter assembly 2. The concentrate outlet interface 213 and the concentrate outlet end 223 are connected through the concentrate outlet path 25.

[0041] In one specific embodiment of this application, such as Figure 2 , Figure 3 As shown, the socket 3 may be provided with a first slot 31, which is used to engage with the first protrusion 521 on the socket cover 52.

[0042] In the structure provided in this specific embodiment, the first protrusion 521 engages with the first slot 31, forming a fastening between the sleeve 3 and the sleeve cover 52. The sleeve cover 52 provides limiting force in the radial and circumferential directions of the sleeve 3, effectively restricting the circumferential rotation and axial displacement freedom of the sleeve 3, thereby improving the shock resistance and water pressure impact resistance of the connection between the filter interface 21 and the equipment interface 511. At the same time, the first slot 31 also serves as a foolproof mechanism.

[0043] Specifically, the first slot 31 may be provided with a limiting groove 311 and a guide slope 312 provided on the side wall of the limiting groove 311. The guide slope 312 can guide the first protrusion 521 to be inserted into the first slot 31, which can improve the assembly efficiency of the socket 3 and the socket cover 52.

[0044] In a specific embodiment of this application, see [reference]. Figure 5 , Figure 6 , Figure 10 The filter element device 1 may include a tube body 4, one end of which is connected to the side of the filter assembly 2, and the other end is provided with a filter interface 21. At least a portion of the filter element water inlet passage 23, at least a portion of the filter element purified water outlet passage 24, and at least a portion of the concentrated water outlet passage 25 may be formed inside the tube body 4. The tube body 4 and the first slot 31 are both arranged radially along the sleeve joint 3, and the extension direction of the tube body 4 intersects the extension direction of the first slot 31.

[0045] In the structure provided in this specific embodiment, the extension direction of the tube body 4 intersects with the extension direction of the first slot 31, so that when the tube body 4 is subjected to water pressure impact along the axial direction of the tube body 4, the first slot 31 can effectively cooperate with the first protrusion 521 to resist the impact, further improving the shock resistance and water pressure impact resistance of the filter interface 21 and the equipment interface 511, and improving the stability and reliability of the connection between the filter element device 1 and the water treatment equipment 5.

[0046] In one specific embodiment of this application, such as Figure 3 , Figure 4 , Figure 5 As shown, the socket 3 includes a shielding part 32 and an exposed part 33. The shielding part 32 is used to fit inside the socket cover 52, and the first slot 31 is disposed between the shielding part 32 and the exposed part 33.

[0047] In the structure provided in this specific embodiment, the sleeve cover 52, in conjunction with the first protrusion 521, effectively limits the connection of the sleeve connector 3. The entire shielding portion 32 of the sleeve connector 3 is surrounded by the sleeve cover 52, which perfectly matches the size, thus improving the anti-counterfeiting and anti-counterfeiting capabilities of the filter element. The exposed portion 33, which is outside the sleeve cover 52, can be used to display parameter information such as the model and service life of the filter element device 1. After the filter element device 1 is assembled with the water treatment equipment 5, only the exposed portion 33 of the sleeve connector 3 is visible, making the overall appearance more concise.

[0048] Optionally, the upper end of the socket 3 can also be completely fitted inside the socket cover 52.

[0049] In a specific embodiment of this application, see [reference]. Figure 3 , Figure 4 The socket 3 may also be provided with a locking component 34, which is connected to the socket 3 and is used to lock the socket cover 52 to the filter element device 1.

[0050] In the structure provided in this specific embodiment, in addition to the insertion and limiting relationship between the device interface 511 and the filter interface 21, and the sleeve limiting relationship between the sleeve connector 3 and the sleeve cover 52, a locking component 34 is also provided to lock the sleeve cover 52, forming a third locking relationship between the filter element device 1 and the water treatment equipment 5, which can further improve the stability and reliability of the connection between the filter element device 1 and the water treatment equipment 5.

[0051] In one specific embodiment of this application, such as Figure 4 As shown, the locking component 34 may include a movable or rotatable locking member 341 and an elastic member 342 for resetting the locking member 341. One end of the elastic member 342 is connected to the locking member 341, and the other end of the elastic member 342 abuts against the sleeve connector 3. The locking member 341 is used to engage with the sleeve cover 52, thereby locking the sleeve cover 52 to the filter element device 1.

[0052] In the structure provided in this specific embodiment, an elastic reset structure is introduced in the locking component 34 to cooperate with the locking member 341. The elastic member 342 can automatically push the locking member 341 and the sleeve cover 52 to lock. Even if there is an external impact, the elastic member 342 can still continuously provide locking force. Its structure is simple and reliable, and the manufacturing and assembly costs are low. It can effectively ensure the stability of the connection between the filter element device 1 and the water treatment equipment 5.

[0053] See Figure 4The socket 3 has a mounting groove 36 and a telescopic hole 37 communicating with the mounting groove 36. The filter assembly 2 also includes a cover 35. A locking member 341 and an elastic member 342 are installed in the mounting groove 36, and the locking member 341 can extend out of the mounting groove 36 through the telescopic hole 37, thereby locking the socket cover 52 to the equipment body 51. The elastic member 342 and the locking member 341 are all built into the mounting groove 36 and the telescopic hole 37. Only one end of the locking member 341 is exposed through the telescopic hole 37 to cooperate with the socket cover 52, so that the overall size of the locking member 34 is small, which is suitable for water treatment equipment 5 with limited installation space.

[0054] Optionally, the locking member 341 may specifically include a pressing post 341a and a snap-fit ​​post 341b fixedly connected to the pressing post 341a. The snap-fit ​​post 341b is used to snap onto the mating sleeve 3, thereby locking the sleeve cover 52 and the filter element device 1. The pressing post 341a is pressed to compress or stretch the elastic member 342, causing the snap-fit ​​post 341b to retract, thereby unlocking the sleeve cover 52 and the filter element device 1. In the structure provided in this specific embodiment, the locking member 341 is divided into two parts: the pressing post 341a and the snap-fit ​​post 341b. Only the exposed pressing post 341a needs to be pressed to retract the snap-fit ​​post 341b into the mounting groove 36, making the operation simple and convenient.

[0055] In one embodiment of this application, see Figure 6 R1 is the distance between the central axes of the two pipes 4 that form the filter element water inlet 23 and the filter element purified water outlet 24. R1 is greater than or equal to 11 mm and less than or equal to 19 mm. Correspondingly, the distance between the central axes of the two pipes 4 that form the water inlet 511a and the purified water outlet 511b is equal to R1.

[0056] See Figure 11 , Figure 11 This is a schematic diagram of an embodiment of the socket connector of this application. The outer contour dimensions of the two pipes 4 forming the filter element water inlet passage 23 and the filter element purified water outlet passage 24 are all equal. R2 is the outer diameter of the sealing protrusion on the two pipes 4 forming the filter element water inlet passage 23 and the filter element purified water outlet passage 24, and R2 is greater than or equal to 6.5 mm and less than or equal to 14.5 mm. R3 is the minimum outer diameter of the two pipes 4 forming the filter element water inlet passage 23 and the filter element purified water outlet passage 24, and R3 is greater than or equal to 4.5 mm and less than or equal to 12.5 mm. R4 is the maximum outer diameter of the two pipes 4 forming the filter element water inlet passage 23 and the filter element purified water outlet passage 24, and R4 is greater than or equal to 7.5 mm and less than or equal to 15.5 mm.

[0057] When the tube body 4 is inserted into the equipment interface 511 of the equipment body 51, the portions of the tube body 4 with radial dimensions R2 and R3 are inserted into the equipment body 51, while the portion with radial dimension R4 can be exposed. The sealing protrusion on the tube body 4 is used to cooperate with the sealing structure inside the equipment body 51 to seal the connection between the equipment interface 511 and the filter interface 21.

[0058] See Figure 5 d1 represents the diameter of filter component 2, which is greater than or equal to 50 mm and less than or equal to 130 mm. R5 is the inner diameter of the inlet 511a and the purified water outlet 511b, which is greater than or equal to 7.5 mm and less than or equal to 15.5 mm. R6 is the inner diameter of the two pipes 4 that form the filter element inlet channel 23 and the filter element purified water outlet channel 24, which is greater than or equal to 2 mm and less than or equal to 8 mm.

[0059] Preferably, R1 can be 15mm. R2 can be 10.5mm. R3 can be 8.5mm. R4 can be 11.5mm. R5 can be 11.5mm. R6 can be 5mm.

[0060] Furthermore, in the case where the filter assembly 2 has a concentrated water outlet 25 and the device interface 511 includes a concentrated water outlet 511c, the pipe body 4 forming the concentrated water outlet 25 may also have the same outer contour dimensions as the two pipe bodies 4 forming the filter element inlet water outlet 23 and the filter element purified water outlet 24. The distance between the central axes of the pipe body 4 forming the concentrated water outlet 511c and the pipe body forming the purified water outlet 511b is equal to R1. R5 can also represent the inner diameter of the pipe body 4 forming the concentrated water outlet 511c.

[0061] In one embodiment, the three pipes 4 forming the filter element inlet water passage 23, the filter element purified water outlet water passage 24, and the concentrated water outlet water passage 25 have the same inner diameter. The inner diameter of the three pipes 4 forming the filter element inlet water passage 23, the filter element purified water outlet water passage 24, and the concentrated water outlet water passage 25 is greater than or equal to 2 mm and less than or equal to 8 mm, and / or, the distance between the central axis of the pipe 4 forming the filter element inlet water passage 23 and the central axis of the pipe 4 forming the filter element purified water outlet water passage 24 is greater than or equal to 11 mm and less than or equal to 19 mm.

[0062] For specific applications, please refer to Figure 10The inner diameter of the three pipes 4 forming the filter element inlet water path 23, the filter element purified water outlet water path 24, and the concentrated water outlet water path 25 is denoted as d2. The distance between the central axis of the pipe 4 forming the filter element inlet water path 23 and the central axis of the pipe 4 forming the filter element purified water outlet water path 24, and the distance between the central axis of the pipe 4 forming the concentrated water outlet water path 25 and the central axis of the pipe 4 forming the filter element purified water outlet water path 24, are equal and are denoted as l2. By setting the inner diameter of each pipe 4 to be greater than or equal to 2mm and less than or equal to 8mm, the smooth flow of water within the pipe 4 can be ensured without making the pipe 4 too large and occupying too much space.

[0063] In a specific embodiment of this application, see [reference]. Figure 11 W1 is the height dimension of socket 3, and W1 is greater than or equal to 10mm. Optionally, W2 is the width dimension of socket 3, and W2 can be greater than or equal to 66mm.

[0064] Optionally, W3 is the distance between the edge of the first slot 31 closest to the tube body 4 and the farthest end of the tube body 4, where W3 is greater than or equal to 15mm and less than or equal to 90mm. In specific applications, W3 can be 15mm, 30mm, 50mm, 70mm, 90mm, etc.

[0065] See Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 7 This application provides a water treatment device 5, including a device body 51 and a sleeve cover 52. The device body 51 is provided with a device interface 511, which is used to connect a water source and the filter interface 21 of the filter element device 1 as described in any of the above embodiments. The sleeve cover 52 is movably connected to the device body 51 and is used to sleeve at least a portion of the sleeve joint 3 of the filter element device 1 to prevent the filter interface 21 from becoming detached from the device interface 511.

[0066] In the structure provided in this specific embodiment, the sleeve 3 and the sleeve cover 52 of the water treatment equipment 5 are fitted together to form a fixed structure independent of the filter interface 21 and the equipment interface 511. When the water treatment equipment 5 operates and generates vibration or water pressure, the sleeve 3, under the mechanical limiting action of the sleeve cover 52, can significantly reduce the relative shaking between the filter interface 21 and the equipment interface 511, avoiding problems such as easy loosening and leakage caused by relying solely on the insertion and fixing of the filter interface 21 and the equipment interface 511. The fitting relationship between the sleeve 3 and the sleeve cover 52 can effectively disperse the stress at the filter interface 21 and the equipment interface 511, reducing the pressure borne by the filter interface 21 and the equipment interface 511, thereby reducing the probability of damage to the filter interface 21 and the equipment interface 511 under stress, and improving the stability and reliability of the connection between the filter element device 1 and the water treatment equipment 5.

[0067] See Figure 2 In one specific embodiment of this application, the sleeve cover 52 includes a movable rod 522 and a cover body 523. The device body 51 may be provided with a rotating shaft 512. One end of the movable rod 522 is rotatably connected to the rotating shaft 512, and the other end of the movable rod 522 is connected to the cover body 523. When the movable rod 522 rotates to the position parallel to the tube 4 of the filter element device 1 and is opposite to the exposed portion 33 of the sleeve 3, the cover body 523 is fitted onto the shielding portion 32 of the sleeve 3, and the sleeve cover 52 is locked to the filter element device 1.

[0068] In the structure provided in this specific embodiment, the movable rod 522 rotates downward 90° around the rotating shaft 512, and the cover body 523 is axially advanced and completely covers the shielding part 32. When disassembling, the movable rod 522 can be lifted in the opposite direction to separate the socket 3 from the socket cover 52, which can take into account reliability, service life, installation space and assembly convenience.

[0069] Optionally, in addition to rotatably connecting the movable rod 522 and the equipment body 51, the equipment body 51 may also be provided with a sliding shaft 513. One end of the movable rod 522 is slidably connected to the sliding shaft 513, and the other end of the movable rod 522 is connected to the cover body 523. When the movable rod 522 slides to be opposite to the exposed part 33 of the sleeve joint 3, the cover body 523 is fitted onto the shielding part 32 of the sleeve joint 3, and the sleeve cover 52 is locked with the filter element device 1.

[0070] In the structure provided in this specific embodiment, the sliding shaft 513 transforms the sleeve cover 52 into a sliding cover mechanism. While effectively compressing the overall size of the water treatment equipment 5, it uses pure axial thrust to complete the highly reliable docking of the sleeve cover 52 and the sleeve connector 3, thereby achieving an effective and stable quick-release solution for the filter element device 1.

[0071] like Figure 4 As shown, in a specific embodiment of this application, the sleeve cover 52 further includes a first protrusion 521. The cover body 523 is used to be sleeved on at least part of the sleeve 3. The first protrusion 521 is disposed on the side surface of the cover body 523 facing the sleeve 3. The first protrusion 521 is used to engage with the first slot 31 on the sleeve 3.

[0072] In the structure provided in this specific embodiment, the first protrusion 521 engages with the first slot 31, forming a fastening between the sleeve 3 and the sleeve cover 52. The sleeve cover 52 provides limiting force in the radial and circumferential directions of the sleeve 3, effectively restricting the circumferential rotation and axial displacement freedom of the sleeve 3, thereby improving the shock resistance and water pressure impact resistance of the connection between the filter interface 21 and the equipment interface 511. At the same time, the first slot 31 also serves as a foolproof mechanism.

[0073] See Figure 4In one specific embodiment of this application, the cover body 523 may be provided with a locking groove 524, which is used to engage with the locking member 341 of the sleeve connector 3 to lock the sleeve cover 52 and the filter element device 1.

[0074] In the structure provided in this specific embodiment, the locking member 341 and the locking groove 524 form a "pin-hole" type fit. After the locking member 341 is inserted into the locking groove 524, the top and bottom end faces of the locking groove 524 abut against the locking member 341, which can limit the upper limit of the sleeve cover 52 in the axial direction of the sleeve 3. The side wall of the locking groove 524 clamps the locking member 341, which can eliminate the relative shaking between the sleeve cover 52 and the sleeve 3 and restrain the displacement of the sleeve 3 in the circumferential direction. It can simultaneously lock the freedom of the sleeve 3 in the axial, radial and circumferential directions, and improve the stability and reliability of the connection between the filter element device 1 and the water treatment equipment 5.
