[0035] Embodiment 1

[0036] See also Figure 1 and Figure 2 The utility model discloses a waterway plate assembly, which includes a waterway plate 1 and a water pipe 2. Specifically, the waterway plate 1 has a first end 16 and a second end 17 that are separated from each other, and the water pipe 2 is arranged at the second end 17. The water pipe 2 is provided with a first flow channel 21 and a second flow channel 22, and the first flow channel 21 and the second flow channel 22 are spaced apart along the axial direction of the water pipe 2. Figure 2 and Figure 3 At least two water guide holes are provided on the waterway plate 1, and the water guide holes extend from the first end 16 to the second end 17, wherein the first flow channel 21 is connected to one of the water guide holes, and the second flow channel 22 is connected to the other water guide hole.

[0037] On the basis of this structure, when using the waterway plate assembly of the utility model, the waterway plate assembly can be first connected to the pipe on the body 4 of the water purification device 3 through the water guide pipe 2. Specifically, the body 4 of the water purification device 3 is provided with multiple pipes, some of which are connected to the raw water faucet to introduce raw water for filtration by the filter element 5; other pipes are used to export the purified water filtered by the filter element 5 for users. When connecting the waterway plate assembly to the pipe on the body 4, the first flow channel 21 and the second flow channel 22 of the water guide pipe 2 can be connected to at least two pipes of the body 4 respectively to achieve waterway communication between the waterway plate assembly and the body 4.

[0038] See also Figure 5 , and then the filter element 5 is arranged on the first end 16 of the waterway plate 1, and the filter element 5 is connected to the water guide hole on the waterway plate 1 by plugging, so as to realize the waterway communication between the filter element 5 and the machine body 4. Since the first flow channel 21 and the second flow channel 22 of the water guide pipe 2 are respectively connected to the two water guide holes, the filter element 5 can be connected to the waterway of the machine body 4 after the filter element 5 is plugged into the water guide hole.

[0039] When the water purification device 3 is working, the body 4 can introduce the pressurized raw water into the filter element 5 through the first flow channel 21 in the water pipe 2 and the water guide hole connected to the flow channel. The clean water produced by the filter element 5 after filtration enters the second flow channel 22 in the water pipe 2 through another water guide hole, and flows out through the pipe of the body 4 for users to use.

[0040] Among them, the first flow channel 21 and the second flow channel 22 are spaced apart and distributed along the axial direction of the water pipe 2, and the two flow channels are isolated from each other and conduct water separately; and the two ends of the water pipe 2 that are far away from each other form flow channel ports, and the first flow channel 21 and the second flow channel 22 can be connected to the pipe of the body 4 through pipe joints at the two flow channel ports. Therefore, raw water can enter the first flow channel 21 from one flow channel port and then be introduced into the filter element 5, and the clean water produced by the filter element 5 enters the second flow channel 22 and then is discharged from another flow channel port. A one-way waterway is formed between the waterway plate 1 and the filter element 5, and the inlet and outlet of the one-way waterway are located at the axial ends of the water pipe 2.

[0041] It should be noted that the conventional waterway plate assembly needs to set up at least three pipes corresponding to the raw waterway, the clean waterway and the wastewater waterway, and at least three pipe joints are set up corresponding to the three pipes to connect with the water purification device 3; the large number of pipes makes the pipeline setting more complicated, and the pipes occupy more space.

[0042] The present application integrates at least two water channels of the waterway plate 1 into the same water pipe 2, and the raw water and the purified water are respectively introduced into and discharged from the filter element 5 via the two flow channels of the water pipe 2 and the two water guide holes on the waterway plate 1, thereby reducing the number of pipes in the waterway plate assembly, simplifying the pipeline setting, and facilitating the connection between the waterway plate 1 and the water purification device 3.

[0043] In addition, the water purification device 3 takes in raw water from one end of the water pipe 2 and discharges purified water from the other end of the water pipe 2. The pipeline is simple and clear, which is convenient for maintenance. In addition, the water guide hole runs from the first end 16 of the waterway plate 1 to the second end 17, the filter element 5 is arranged at the first end 16, the water pipe 2 is arranged at the second end 17, and the waterway plate 1 is connected to the body 4 through the two ends of the water pipe 2, so that the connection between the components is compact and the replacement of the filter element 5 is convenient.

[0044] Further, three water guide holes are provided on the waterway plate 1, and the three water guide holes are respectively a first water guide hole 11, a second water guide hole 12 and a third water guide hole 13. In addition, the second flow channel 22 includes an inner flow channel 25 and an outer flow channel 26, and the outer flow channel 26 is arranged on the outer periphery of the inner flow channel 25. Among them, the first flow channel 21 is connected to the first water guide hole 11, the inner flow channel 25 is connected to the second water guide hole 12, and the outer flow channel 26 is connected to the third water guide hole 13.

[0045] Based on this structure, the first flow channel 21 is a raw water channel, the inner flow channel 25 and the outer flow channel 26 are waste water channels and clean water channels, respectively. When the water purifier 3 is in use, raw water is introduced into the filter element 5 through the first flow channel 21 and the first water guide hole 11, and the clean water and waste water produced by the filter element 5 after filtering the raw water are respectively discharged through the second water guide hole 12 and the inner flow channel 25, and the third water guide hole 13 and the outer flow channel 26.

[0046] Therefore, this embodiment integrates three flow channels into the same water conduit 2, which not only reduces the number of pipes in the waterway plate assembly, but also simplifies the direction of the waterway, making the connection between the waterway plate 1 and the body 4 more convenient.

[0047] In some embodiments, the water pipe 2 includes a first water pipe section and a second water pipe section, and the first water pipe section and the second water pipe section are connected along the axial direction of the water pipe 2. The first flow channel 21 is located in the first water pipe section, the second flow channel 22 is located in the second water pipe section, and the first flow channel 21 and the second flow channel 22 are isolated from each other.

[0048] That is, the water pipe 2 is an integrally formed structure, and a partition plate may be integrally formed in the middle of the water pipe 2 to separate the inside of the water pipe 2 into a first flow channel 21 and a second flow channel 22, so that the first flow channel 21 and the second flow channel 22 conduct water separately. By integrally forming the first water pipe section and the second water pipe section in the water pipe 2, the number of parts of the waterway plate assembly can be reduced, and the overall structure of the waterway plate assembly can be made more compact.

[0049] In this embodiment, the water pipe 2 includes a first water pipe 23 and a second water pipe 24 , and the first water pipe 23 and the second water pipe 24 are spaced apart along the axial direction of the water pipe 2 ; wherein the first flow channel 21 is located in the first water pipe 23 , and the second flow channel 22 is located in the second water pipe 24 .

[0050] That is, the water pipe 2 includes two pipes, and the two pipes are arranged in parallel along the axial direction of the water pipe 2; at the same time, at least one of the pipes has multiple water channels integrated therein.

[0051] See also Figure 1 and Figure 2 The three water guide holes are arranged in the axial interval between the first water guide pipe 23 and the second water guide pipe 24 .

[0052] Since the first water pipe 23 and the second water pipe 24 are arranged at intervals along the axial direction of the water pipe 2, a gap is formed between the first water pipe 23 and the second water pipe 24. By arranging the three water holes in the gap, the space of the waterway plate 1 can be fully utilized and the distance between the water holes and the flow channel in the water pipe 2 can be shortened.

[0053] The first water guide hole 11 and the third water guide hole 13 are spaced apart along the axial direction of the water guide pipe 2, and the second water guide hole 12 and the third water guide hole 13 are spaced apart along the radial direction of the water guide pipe 2. The specific communication mode between the water guide hole and the flow channel is as follows: the water guide hole is provided with a connecting joint on the second end 17 of the waterway plate 1, and the connecting joint passes through a side wall of the water guide pipe 2.

[0054] Thus, the waterway plate assembly can have water inlet and outlet from both ends of the water conduit 2 , and conduct water through the first end 16 and the second end 17 of the waterway plate 1 , thereby reducing water loss and preventing water leakage.

[0055] Furthermore, the second water conduit 24 includes an inner pipe section 27 and an outer pipe section 28 , and the outer pipe section 28 is sleeved on the outer circumference of the inner pipe section 27 ; wherein the inner flow channel 25 is located in the inner pipe section 27 , and the outer flow channel 26 is located between the inner pipe section 27 and the outer pipe section 28 .

[0056] Based on this structure, when the water purification device 3 is working, the clean water and waste water generated after the filter element 5 filters the raw water enter the inner pipe section 27 and the outer pipe section 28 through the second water guide hole 12 and the third water guide hole 13 on the water channel plate 1 respectively, and are then discharged from the same end of the water pipe 2 respectively.

[0057] That is, the present application introduces or exports water through the water guide hole in the middle of the waterway plate 1, and simultaneously introduces water through one end of the water guide pipe 2 and two ends of the water guide pipe 2, so as to realize the waterway circulation between the machine body 4 and the filter element 5. Since the waterway enters at one end of the water guide pipe 2 and exits at the other end of the water guide pipe 2, when the waterway plate assembly leaks, it is convenient to detect and repair from the interfaces at both ends of the water guide pipe 2.

[0058] In order to realize multi-way water inlet and outlet of the water conduit 2, a first connecting piece 29 and a second connecting piece 30 are respectively provided at both ends of the water conduit 2, wherein one end of the first connecting piece 29 is connected to the first flow channel 21, and the other end of the first connecting piece 29 is provided with a water pipe interface 31, and the water pipe interface 31 is connected to the first flow channel 21;

[0059] In addition, one end of the second connecting piece 30 is connected to the second flow channel 22 , and the other end of the second connecting piece 30 is provided with two water pipe interfaces 31 , and the two water pipe interfaces 31 are respectively connected to the inner flow channel 25 and the outer flow channel 26 in the second flow channel 22 .

[0060] Specifically, the first connecting piece 29 and the second connecting piece 30 are respectively connected to the flow channel ports of the first flow channel 21 and the second flow channel 22. The first connecting piece 29 and the second connecting piece 30 are elbow pipe sections, which can connect the water pipe 2 and the pipeline on the body 4 and can change the direction of the pipeline.

[0061] Based on this structure, a flow channel is provided inside the first connecting piece 29, and two flow channels are provided inside the second connecting piece 30. The two flow channels in the second connecting piece 30 are respectively connected to the inner flow channel 25 and the outer flow channel 26. The water pipe interface 31 on the connecting piece can be plugged and connected to the pipe on the body 4.

[0062] During use, the raw water is pressurized by the pump body and then introduced into the filter element 5 in sequence from the water inlet pipe of the body 4 - the water pipe interface 31 of the first connecting piece 29 - the flow channel in the first connecting piece 29 - the first flow channel 21 of the water pipe 2 - the first water guide hole 11, and the clean water / waste water produced by the filter element 5 is discharged in sequence from the second water guide hole 12 / the third water guide hole 13-the inner flow channel 25 / the outer flow channel 26 of the water pipe 2 - a flow channel / another flow channel in the second connecting piece 30 - a water pipe interface 31 of the second connecting piece 30 / another water pipe interface 31 - a water outlet pipe / another water outlet pipe of the body 4.

[0063] Thus, the three water channels are introduced or exported into the pipeline of the machine body 4 via two connecting pieces at both ends of the water pipe 2, which facilitates the connection between the water channel plate assembly and the machine body 4 and is less likely to cause the problem of loose interfaces.

[0064] Further, see Figure 3A water channel joint 14 is provided on the water channel plate 1, and the water channel joint 14 is connected to the water guide hole.

[0065] Thus, the water channel plate 1 can also be connected to the water channel interface 51 on the filter element 5 through the water channel connector 14, so as to achieve the connection between the filter element 5 and the water conduit 2. The water channel connector 14 can be plugged into the water channel interface 51 on the filter element 5, making the replacement of the filter element 5 more convenient.

[0066] Further, see Figure 3 A locking piece 15 is provided on the waterway plate 1 , and the locking piece 15 is used to be locked and connected with the connecting piece 52 on the filter element 5 .

[0067] Based on this structure, the locking member 15 includes a moving plate and a clamping groove 151 provided on the moving plate, and the connecting member 52 on the filter element 5 can be a clamping rib or a clamping hook. When the filter element 5 is connected to the waterway connector 14 on the waterway plate 1 through the waterway interface 51, the clamping rib or the clamping hook on the filter element 5 is inserted into the clamping groove 151 on the moving plate. Then, the moving plate moves under the action of an external force, so that the clamping rib or the clamping is locked in the clamping groove 151.

[0068] When the water purifier 3 is working, the water in the waterway of the waterway plate 1 will have a certain water pressure; when the filter element 5 is directly inserted into the waterway plate 1, the filter element 5 may be ejected under the action of the water pressure, causing the filter element 5 to separate from the waterway plate 1. However, the waterway plate 1 of the present application is connected and locked with the filter element 5 through the locking member 15. After the waterway plate 1 and the filter element 5 are locked and connected, during the operation of the water purifier 3, the water pressure in the waterway of the waterway plate 1 will not drive the filter element 5 away from the waterway plate 1, thereby ensuring the conduction of the waterway between the waterway plate 1 and the filter element 5.

[0069] Embodiment 2

[0070] Different from the first embodiment, this embodiment discloses a water purification device 3, see Figure 6 and Figure 7 The water purification device 3 specifically includes a body 4, a filter element 5 and the waterway plate assembly in the first embodiment. The waterway plate assembly is rotatably connected to the body 4 through the water guide pipe 2. Figure 4 The bottom end of the filter element 5 is provided with a water channel interface 51, and the water channel interface 51 is connected to the water guide hole. The first flow channel 21 and the second flow channel 22 in the water guide pipe 2 are used to guide water to enter or flow out of the water channel interface 51.

[0071] Based on this structure, see Figure 7 A mounting cavity 41 is provided in the machine body 4 , a mounting seat 42 is provided at the bottom of the mounting cavity 41 , a mounting groove 44 is provided in the middle of the mounting seat 42 , and rotation grooves 43 are provided on both sides of the mounting groove 44 .

[0072] When using the water purification device 3 of the utility model, during assembly, the waterway plate assembly can be first embedded in the installation groove 44, and at the same time, the two ends of the water pipe 2 can be installed in the rotating groove 43, and then the waterway plate assembly can be connected to the pipe on the body 4 of the water purification device 3 through the water pipe 2. Specifically, a plurality of pipes are provided on the body 4 of the water purification device 3, and the first flow channel 21 and the second flow channel 22 of the water pipe 2 can be respectively connected to at least two pipes of the body 4 through the connecting pieces at the two ends of the water pipe 2, so as to realize the waterway connection between the waterway plate assembly and the body 4 of the water purification device 3.

[0073] Then install the filter element 5 into the installation cavity 41, and make the multiple water channel interfaces 51 on the filter element 5 be inserted and connected with the multiple water guide holes one by one; because the first flow channel 21 and the second flow channel 22 of the water pipe 2 are respectively connected with the two water guide holes, the filter element 5 can be connected with the pipeline of the body 4 of the water purification device 3 after the filter element 5 is inserted into the water guide hole.

[0074] When the water purification device 3 is working, the raw water can enter the filter element 5 through the water channel interface 51 under the guidance of the first flow channel 21 of the water pipe 2. The clean water produced after the filter element 5 filters and purifies the raw water enters the second flow channel 22 of the water pipe 2 through other water channel interfaces 51, and is then discharged to the outside of the water purification device 3.

[0075] Therefore, the two flow channels or three flow channels of the waterway plate 1 can be integrated in the same water pipe 2, and the raw water and the purified water are respectively introduced into and exported from the filter element 5 via the two flow channels of the water pipe 2 and the two waterway interfaces 51 on the filter element 5, thereby reducing the number of pipes of the waterway plate assembly, simplifying the pipeline setting, and facilitating the connection between the waterway plate 1 and the water purification device 3.

[0076] It should be noted that a locking member 15 is also provided on the waterway plate assembly, and the locking member 15 is used to lock the filter element 5 in the installation cavity 41 when the filter element 5 is connected to the waterway plate assembly by waterway. Specifically, the locking member 15 includes a moving plate and a clamping groove 151 provided on the moving plate, and a clamping rib is provided on the filter element 5; when the filter element 5 is connected to the waterway connector 14 on the waterway plate 1 by plugging through the waterway interface 51, the clamping rib on the filter element 5 is plugged into the clamping groove 151 on the moving plate.

[0077] Since the waterway plate assembly is rotatably connected to the rotating groove 43 through the water conduit 2, the waterway plate assembly can drive the filter element 5 to rotate on the machine body 4. Among them, a protruding block 45 is provided on the machine body 4, and a pressing block 152 is provided on the side of the movable plate close to the protruding block 45. During the rotation process, the waterway plate assembly can make the pressing block 152 of the movable plate approach or move away from the protruding block 45. Therefore, when the clamping rib on the filter element 5 is inserted into the clamping groove 151 on the movable plate, the waterway plate assembly can be rotated so that the pressing block 152 of the movable plate approaches the protruding block 45 on the machine body 4 and is pressed by the protruding block 45, thereby driving the movable plate to move on the waterway plate 1, thereby causing the clamping groove 151 to be dislocated from the clamping rib, and the clamping groove 151 locks the clamping rib. At this time, the filter element 5 cannot be detached from the waterway plate 1.

[0078] Since the waterway plate 1 is locked and connected to the filter element 5 , during operation of the water purification device 3 , the water pressure in the waterway of the waterway plate 1 will not drive the filter element 5 away from the waterway plate 1 , thereby ensuring the conduction of the waterway between the waterway plate 1 and the filter element 5 .

[0079] When replacing the filter element, the waterway plate assembly can be rotated so that the pressing block 152 of the movable plate is away from the protruding block 45 on the body 4, the pressing block 152 is not pressed by the protruding block 45, and the movable plate can be reset, so that the clamping groove 151 and the clamping rib are arranged oppositely, and the clamping rib can be withdrawn from the clamping groove 151. In this way, the filter element 5 can be taken out of the installation cavity 41 for replacement.

[0080] That is, the present application integrates multiple waterways of the waterway plate 1 into the same water conduit 2, and the waterway plate assembly can be rotatably connected to the body 4 through the water conduit 2, and the filter element 5 is driven to rotate by the waterway plate assembly, thereby realizing the locking and unlocking of the filter element 5 and the waterway plate 1.
