[0002] With the advancement of technology, people have developed diverse needs for domestic water. Water purification equipment can filter the input water and then output the filtered water, providing users with water that meets their needs and greatly facilitating their lives. Water purification equipment generally consists of interconnected filter cartridges and a main body.

In actual use, the water input to the filter cartridges from the main body typically has a certain water pressure, which tests the robustness of the pipes connecting the filter cartridges to the main body. Water pressure can easily cause pipe vibration. If the reliability of the pipes cannot be effectively guaranteed, the filter cartridges are prone to leakage, pipe damage, or even filter cartridge detachment during use due to pipe vibration, significantly affecting the stability of the water purification equipment.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] With the advancement of technology, people have developed diverse needs for domestic water. Water purification equipment can filter the input water and then output the filtered water, providing users with water that meets their needs and greatly facilitating their lives. Water purification equipment 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 cartridges gradually decreases. To maintain stable water quality in the output water, the filter cartridges are usually configured as removable consumables. In actual use, the water input to the filter cartridges from the main body typically has a certain water pressure, which tests the robustness of the pipes connecting the filter cartridges to the main body. Water pressure can easily cause pipe vibration. If the reliability of the pipes cannot be effectively guaranteed, the filter cartridges are prone to leakage, pipe damage, or even filter cartridge detachment during use due to pipe vibration, significantly affecting the stability of the water purification equipment.

[0024] 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.

[0025] See Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 1 This is a schematic diagram of the assembly structure of an embodiment of the water purification equipment of this application. Figure 2 This is a schematic diagram of the assembly structure of an embodiment of the filter element assembly of this application. Figure 5 This is a schematic diagram of the assembly structure of another embodiment of the water purification equipment of this application. Figure 6 This is a schematic diagram of the assembly structure of another embodiment of the filter element assembly of this application. A specific embodiment of this application provides a filter element connector 1, including a base 2, a tube 3, and a support frame 4. The base 2 is used to connect to the filter element body 6. The first end of the tube 3 is connected to the base 2, and the second end of the tube 3 is provided with a connector interface 31 that can be inserted into the device interface 71 on the device body 7. The second end of the tube 3 is arranged radially parallel to the base 2. The support frame 4 connects the second end of the tube 3 and the base 2.

[0026] In the structure provided in this specific embodiment, by providing a support frame 4 for the pipe body 3, the support frame 4 connects the second end of the pipe body 3 to the base 2 in a triangular or cantilever integrated structure, which can provide support for the pipe body 3. Under water pressure impact, the support frame 4 can alleviate the vibration phenomenon of the pipe body 3. Furthermore, when the filter element connector 1 is inserted into or removed from the equipment body 7, the pulling / pushing force during the insertion and removal of the filter element can be transmitted to the base 2 through the support frame 4, distributing the load on the pipe body 3, reducing the risk of bending or even fatigue cracking of the first end of the pipe body 3, and effectively improving the stability of the water purification equipment.

[0027] like Figure 6 As shown, the pipe body 3 may include a water inlet pipe and a purified water outlet pipe, the device interface 71 may include a water inlet interface and a purified water outlet interface, and the filter media in the filter element body 6 may have a water inlet end and a purified water outlet end. The first end of the water inlet pipe is connected to the base 2, and the second end of the water inlet pipe is used to connect to the water inlet interface of the device body 7. A water inlet channel is formed inside the water inlet pipe to connect the water inlet end and the water inlet interface of the filter element body 6. The first end of the purified water outlet pipe is connected to the base 2, and the second end of the purified water outlet pipe is used to connect to the purified water outlet interface of the device body 7. A purified water outlet channel is formed inside the purified water outlet pipe to connect the purified water outlet end and the purified water outlet interface of the filter element body 6.

[0028] Further, see Figure 2 The pipe body 3 may also include a concentrate outlet pipe, and the equipment interface 71 may also include a concentrate outlet interface. The filter material in the filter element body 6 may also have a concentrate outlet end. The first end of the concentrate outlet pipe is connected to the base 2, and the second end of the concentrate outlet pipe is used to connect to the concentrate outlet interface of the equipment body 7. A concentrate outlet channel is formed inside the concentrate outlet pipe to connect the concentrate outlet end of the filter element body 6 and the concentrate outlet interface.

[0029] like Figure 2 , Figure 6 As shown in a specific embodiment of this application, the base 2 includes a connector body 21 and a socket 22. One end of the socket 22 is used to connect to the filter element body 6, and the other end of the socket 22 is connected to the bottom surface of the connector body 21. The tube 3 is connected to the side of the connector body 21. The support frame 4 is arranged along the axial direction of the filter element body 6 and connects the second end of the tube 3 and the socket 22.

[0030] In the structure provided in this specific embodiment, the support frame 4 is arranged along the axial direction of the filter element. The axial force generated by the water pressure when inserting or removing the filter element connector 1 or the input pipe 3 can be transmitted almost linearly to the socket 22 through the support frame 4, resulting in a stable and reliable shock absorption effect. At the same time, the pull-out force is jointly borne by the support frame 4 and the socket 22, and the wall thickness of the pipe 3 can be further reduced, so that the filter element connector 1 can maintain good strength while being material-saving and lightweight.

[0031] See Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 4 yes Figure 2 A schematic diagram of the cross-sectional structure shown in section DD. Figure 8 yes Figure 6The cross-sectional view shown in Figure BB is a schematic diagram. In a specific embodiment of this application, the outer peripheral surface of the socket 22 is arc-shaped, and the support frame 4 is disposed at the edge of the socket 22 and extends parallel to the outer peripheral surface of the socket 22 to connect to the pipe body 3. The arc of the side of the support frame 4 connecting to the outer peripheral surface of the socket 22 is 20°~50°, and the surface of the support frame 4 facing the connector body 21 is flat.

[0032] In the structure provided in this specific embodiment, the arc-shaped socket 22 cooperates with the support frame 4 with an arc of 20°~50°, giving the support frame 4 a certain degree of resistance to bending and torsion, thereby providing continuous support to the pipe body 3 from multiple directions and significantly reducing the torsional deformation of the support frame 4 under insertion, removal or water pressure impact. The surface of the support frame 4 facing the connector body 21 is flat, giving the support frame 4 a certain thickness, further improving the bending resistance of the support frame 4.

[0033] Optionally, the filter element connector 1 includes a second reinforcing rib, which is disposed on the support frame 4 and can provide support for the support frame 4, further improving the bending and torsional strength of the support frame 4. Specifically, the second reinforcing rib can be disposed on the side surface of the support frame 4 facing the connector body 21 to reduce the mutual influence between the external environment and the second reinforcing rib.

[0034] like Figure 2 , Figure 6 As shown in a specific embodiment of this application, the number of tubes 3 can be multiple, and the multiple tubes 3 are arranged in parallel. The width of the support frame 4 is the distance between the central axes of the two outermost tubes 3.

[0035] In the structure provided in this specific embodiment, the width of the support frame 4 is directly based on the "distance between the center axes of the two outermost tubes". This ensures that all tubes 3 are connected precisely without creating redundancy in the width direction that would affect the width of the filter element connector 1. This saves material and installation space while also providing effective support for the tubes 3. Furthermore, the support frame 4 can connect multiple tubes 3, forming an "outer frame" with the outermost tube 3. Each tube 3 is constrained by this "outer frame", which further enhances the structural strength of the support frame 4 and the tubes 3.

[0036] like Figure 3 As shown, Figure 3 yes Figure 2 The cross-sectional view shown in Figure CC is a schematic diagram. In a specific embodiment of this application, multiple tubes 3 are disposed on the same side of the connector body 21, and the filter element connector 1 also includes tube body reinforcing ribs 5. The tube body reinforcing ribs 5 are disposed on the support frame 4 and connect the side of any tube 3 facing other tubes 3.

[0037] In the structure provided in this specific embodiment, the pipe body reinforcing rib 5 increases the connection between the side of the pipe body 3 and the support frame 4, further helping to distribute the torque generated by insertion / removal or water pressure on the first end of the pipe body 3, significantly reducing the stress at the first end of the pipe body 3 and effectively improving the deformation resistance of the pipe body 3. Furthermore, the pipe body reinforcing rib 5 is only arranged on adjacent sides of the pipe body 3, utilizing the "dead corner" space between the pipe bodies 3, without additionally increasing the outer contour dimensions of the connector body 21, thus reducing the required installation space and making it suitable for miniaturized water purification equipment applications.

[0038] like Figure 2 , Figure 6 As shown in a specific embodiment of this application, the base 2 further includes a connecting flange 23, which is connected to the side of the connector body 21 and extends to the second end of the tube body 3. The connecting flange 23 is connected to the tube body 3.

[0039] In the structure provided in this specific embodiment, without increasing the radial dimension of the connector body 21 itself, a continuous structure is formed between the connector body 21 and the pipe body 3 by setting a connecting flange 23. The torque generated by insertion / removal or water pressure is transmitted to other parts of the connector body 21 through the structural body, which can significantly reduce stress concentration at the root of the pipe body 3, reduce the risk of damage to the pipe body 3 and the support frame 4, and improve the stability of the water purification equipment. The connecting flange 23 is equivalent to adding a "lateral support arm" to the pipe body 3, making the coaxiality of the pipe body 3 and the connector body 21 higher, which can reduce the shaking or deflection of the pipe body 3, and further improve the reliability of the docking between the connector interface 31 and the equipment interface 71.

[0040] like Figure 3 As shown in a specific embodiment of this application, there can be multiple pipe bodies 3. A groove 24 is provided between the connecting flange 23 and the connector body 21. A connecting part 25 is provided at the bottom of the groove 24. The connecting part 25 connects multiple pipe bodies 3.

[0041] In the structure provided in this specific embodiment, the trough 24 connects the connecting flange 23, the joint body 21, the connecting part 25, and multiple pipes 3 to form a continuous closed section on the same connecting part 25, achieving an effect similar to a box beam, which can effectively improve the overall bending and torsional stiffness. The trough 24 and connecting part 25 can save materials while connecting multiple pipes 3, allowing them to share the torque, thus improving the overall bending and torsional stiffness of the multiple pipes 3.

[0042] like Figure 3 As shown in a specific embodiment of this application, the connector body 21 may further include a first reinforcing rib 26, which is disposed on the side of the connector body 21 connected to the pipe body 3. One end of the first reinforcing rib 26 is connected to the connecting part 25, and the other end of the first reinforcing rib 26 is connected to the socket 22.

[0043] In the structure provided in this specific embodiment, the first reinforcing rib 26 is supported between the connecting part 25 and the sleeve seat 22, forming a load-bearing structure along the axial direction of the base 2, which can alleviate the bending moment and stress concentration at the first end of the pipe body 3 and the connector body 21. Moreover, the first reinforcing rib 26 and the side of the connector body 21 form a "T"-shaped cross section, which simultaneously improves the axial and radial stiffness of the filter element connector 1 as a whole.

[0044] Optionally, such as Figure 3 , Figure 4 As shown, the first reinforcing rib 26 has a certain angle in the radial direction of the connector body 21 and is connected to the water channel reinforcing rib 27 inside the connector body 21, which is used to provide support for the filter water channel 61, making the entire filter element assembly more integrated and further dispersing the torque on the tube body 3.

[0045] In one embodiment of this application, see Figure 11 , Figure 11 yes Figure 6 A magnified structural diagram of region Y. R1 is the distance between the central axes of the two pipe bodies 3, which serve as the water inlet pipe and the purified water outlet pipe. 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 water inlet interface and the purified water outlet interface in the main body 7 of the equipment is equal to R1.

[0046] See Figure 12 , Figure 12 This is a schematic diagram of a filter element connector according to an embodiment of this application. The outer contour dimensions of the two pipe bodies 3, serving as the water inlet pipe and the purified water outlet pipe, are equal. R2 is the outer diameter of the sealing protrusion on the two pipe bodies 3, which 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 pipe bodies 3, which 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 pipe bodies 3, which is greater than or equal to 7.5 mm and less than or equal to 15.5 mm.

[0047] When the second end of the tube 3 is inserted into the equipment interface 71 of the equipment body 7, the portions of the tube 3 with radial dimensions R2 and R3 are inserted into the equipment body 7, while the portion with radial dimension R4 can be exposed. The sealing protrusion on the tube 3 is used to cooperate with the sealing structure inside the equipment body 7 to seal the connection between the equipment interface 71 and the connector interface 31.

[0048] See Figure 10 , Figure 10 yes Figure 5The cross-sectional view shown in section EE is a schematic diagram. d1 represents the diameter of the filter element body 6, which is greater than or equal to 50 mm and less than or equal to 130 mm.

[0049] R5 is the inner diameter of the device interface 71, 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 pipe bodies 3 that serve as the water inlet pipe and the purified water outlet pipe, which is greater than or equal to 2 mm and less than or equal to 8 mm.

[0050] 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.

[0051] Furthermore, in the case where the pipe body 3 includes a concentrated water outlet pipe, a concentrated water outlet channel is formed inside the concentrated water outlet pipe, and the second end of the concentrated water outlet pipe is used to connect to the concentrated water outlet interface of the main body 7, the pipe body 3 serving as the concentrated water outlet pipe may also have the same outer contour dimensions as the two pipe bodies 3 serving as the inlet pipe and the purified water outlet pipe. The distance between the central axes of the pipe body 3 serving as the concentrated water outlet pipe and the pipe body 3 serving as the purified water outlet pipe is equal to R1. R5 can also represent the inner diameter of the pipe body 3 serving as the concentrated water outlet pipe.

[0052] In one embodiment, the three pipes 3 serving as the water inlet pipe, the purified water outlet pipe, and the concentrated water outlet pipe have the same inner diameter. The inner diameter of the three pipes 3 serving as the water inlet pipe, the purified water outlet pipe, and the concentrated water outlet pipe is greater than or equal to 2 mm and less than or equal to 8 mm. Optionally, the distance between the central axis of the pipe 3 serving as the water inlet pipe and the central axis of the pipe 3 serving as the purified water outlet pipe is greater than or equal to 11 mm and less than or equal to 19 mm.

[0053] For specific applications, please refer to Figure 9 , Figure 9 yes Figure 2 A magnified structural diagram of region X. The inner diameter of the three pipes 3—the inlet pipe, the purified water outlet pipe, and the concentrated water outlet pipe—is denoted as d2. The distance between the central axis of the inlet pipe 3 and the central axis of the purified water outlet pipe 3, and the distance between the central axis of the concentrated water outlet pipe 3 and the central axis of the purified water outlet pipe 3, are equal and denoted as l2. By setting the inner diameter of each pipe 3 to be greater than or equal to 2mm and less than or equal to 8mm, smooth water flow within the pipe 3 is ensured without making the pipe 3 too large and thus occupying excessive space.

[0054] In a specific embodiment of this application, see [reference]. Figure 1 and Figure 12The connector body 21 has a first side surface 211 at the end away from the socket 22, and the socket 22 connects to the end of the connector body 21 to form a second side surface 221. W1 is the height difference between the first side surface 211 and the second side surface 221, and W1 is greater than or equal to 10mm.

[0055] Optionally, W2 is the width dimension of the connector body 21, and W2 can be greater than or equal to 66mm.

[0056] Optionally, the main body 7 of the device may include a locking structure that cooperates with the connector body 21 to lock the filter element connector 1 to the main body 7 of the device.

[0057] Optionally, the first side 211 of the connector body 21 may be provided with a transverse groove 8 for engaging the equipment body 7. The locking structure may include an insert rod, in which case the first side 211 of the connector body 21 may have a transverse groove 8 corresponding to the insert rod, and the insert rod is inserted into the transverse groove 8 to lock the connector body 21 to the equipment body 7. W3 is the distance from the edge of the transverse groove 8 on the connector body 21 to the second end of the tube body 3, and 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.

[0058] like Figure 2 , Figure 6 As shown in the figure, this application provides a filter element assembly, including a filter element body 6 and a filter element connector 1 as described in any of the above embodiments. The filter element body 6 is provided with a water filtration channel 61, and the connector interface 31 of the filter element connector 1 is used to connect the water filtration channel 61 and the device interface 71 of the device body 7.

[0059] In the structure provided in this specific embodiment, by providing a support frame 4 for the pipe body 3, the support frame 4 connects the second end of the pipe body 3 to the base 2 in a triangular or cantilever integrated structure, which can provide support for the pipe body 3. Under water pressure impact, the support frame 4 can alleviate the vibration phenomenon of the pipe body 3. Furthermore, when the filter element connector 1 is inserted into or removed from the equipment body 7, the pulling / pushing force during the insertion and removal of the filter element can be transmitted to the base 2 through the support frame 4, distributing the load on the pipe body 3, reducing the risk of bending or even fatigue cracking of the first end of the pipe body 3, and effectively improving the stability of the water purification equipment.

[0061] In the structure provided in this specific embodiment, by providing a support frame 4 for the pipe body 3, the support frame 4 connects the second end of the pipe body 3 to the base 2 in a triangular or cantilever integrated structure, which can provide support for the pipe body 3. Under water pressure impact, the support frame 4 can alleviate the vibration phenomenon of the pipe body 3. Furthermore, when the filter element connector 1 is inserted into or removed from the equipment body 7, the pulling / pushing force during the insertion and removal of the filter element can be transmitted to the base 2 through the support frame 4, distributing the load on the pipe body 3, reducing the risk of bending or even fatigue cracking at the first end of the pipe body 3, and effectively improving the stability of the water purification equipment.
