[0035] Embodiment 1

[0036] See also Figure 1 and Figure 2 The utility model discloses a waterway plate assembly with inner and outer flow channels, 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 an inner flow channel 21 and an outer flow channel 22, and the outer flow channel 22 penetrates the water pipe 2 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 inner flow channel 21 is connected to one of the water guide holes, and the outer 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 pipeline on the water purifier 3 through the water guide pipe 2. Specifically, a plurality of pipelines are provided on the body 4 of the water purifier 3, some of which are connected to the raw water faucet to introduce raw water for filtration by the filter element 5; other pipelines are used to export purified water for users. When connecting the waterway plate assembly to the pipeline on the body 4, the inner flow channel 21 and the outer flow channel 22 of the water guide pipe 2 can be connected to at least two pipelines on the body 4 respectively, so as to realize the waterway communication between the waterway plate assembly and the water purifier 3.

[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 waterway plate 1. Since the inner flow channel 21 and the outer 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 pipeline of the water purifier 3 after the filter element 5 is plugged into the water guide hole.

[0039] When the water purifier 3 is working, the body 4 can allow the pressurized raw water to flow into the filter element 5 through a flow channel in the water pipe 2 and a water guide hole connected to the flow channel. The clean water produced by the filter element 5 after filtration enters another flow channel 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] It should be noted that the conventional waterway plate assembly needs to set up at least three pipes corresponding to the raw waterway, the purified waterway and the wastewater waterway, and set up at least three pipe interfaces correspondingly to connect with the water purifier 3; the large number of pipes makes the pipeline setting more complicated, and the pipes take up more space.

[0041] The present application integrates two of the flow channels of the waterway plate 1 into the same water pipe 2, and the raw water and 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 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 purifier 3.

[0042] The outer flow channel 22 penetrates the water conduit 2 along the axial direction of the water conduit 2, so that both ends of the outer flow channel 22 can form flow channel ports, and the inner flow channel 21 can be provided with a pipe joint at the flow channel port at at least one end to connect with the pipe on the body 4. In addition, the water guide hole penetrates 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 conduit 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 conduit 2, so that the connection between the components is compact, which is convenient for replacing the filter element 5.

[0043] In some embodiments, 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. Correspondingly, two inner flow channels 21 and an outer flow channel 22 are provided in the water pipe 2, and the two inner flow channels 21 are respectively a first inner flow channel and a second inner flow channel, and the first inner flow channel and the second inner flow channel both penetrate the water pipe 2 along the axial direction of the water pipe 2, and the second inner flow channel, the first inner flow channel, and the outer flow channel 22 are coaxially arranged in sequence from inside to outside along the radial direction of the water pipe 2. Among them, the outer flow channel 22 is connected to the first water guide hole 11, the first inner flow channel is connected to the second water guide hole 12, and the second inner flow channel is connected to the third water guide hole 13.

[0044] Based on this structure, the outer flow channel 22 is the raw water channel, and the first inner flow channel and the second inner flow channel are the waste water channel and the purified water channel, respectively. When the water purifier 3 is in use, raw water is introduced into the filter element 5 through the outer flow channel 22 and the first water guide hole 11, and the purified 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 first inner flow channel, and the third water guide hole 13 and the second inner flow channel.

[0045] Among them, the water outlets of the first inner flow channel and the second inner flow channel can be set at the same end of the water pipe 2, and the water inlet of the outer flow channel 22 is set at the other end of the water pipe 2; thus, the axial ends of the water pipe 2 form a water path with water inlet at one end and water outlet at both ends.

[0046] Therefore, this embodiment integrates three flow channels into the same water pipe 2, reduces the number of pipes in the water circuit plate assembly, and makes the connection between the water circuit plate 1 and the body 4 of the water purifier 3 more convenient; and, since the water enters one end of the water circuit 2 and exits the other end of the water circuit 2, when the water circuit plate assembly leaks, it is convenient to detect and repair from the interfaces at both ends of the water pipe 2.

[0047] In this embodiment, 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; an inner flow channel 21 and an outer flow channel 22 are provided in the water guide pipe 2, wherein the inner flow channel 21 includes a first inner flow channel section 23 and a second inner flow channel section 24, and the first inner flow channel section 23 and the second inner flow channel section 24 are arranged along the axial direction of the water guide pipe 2. Correspondingly, the outer flow channel 22 is connected to the first water guide hole 11, the first inner flow channel section 23 is connected to the second water guide hole 12, and the second inner flow channel section 24 is connected to the third water guide hole 13.

[0048] Based on this structure, the outer flow channel 22 is the raw water channel, and the first inner flow channel section 23 and the second inner flow channel section 24 are the waste water channel and the clean water channel, respectively. When the water purifier 3 is in use, raw water is introduced into the filter element 5 through the outer flow channel 22 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 first inner flow channel section 23, and the third water guide hole 13 and the second inner flow channel section 24.

[0049] Among them, the first inner flow channel section 23 and the second inner flow channel section 24 are arranged along the axial direction of the water pipe 2, the outer flow channel 22 is arranged on the outer periphery of the first inner flow channel section 23 and the second inner flow channel section 24, and the outer flow channel 22 runs through the water pipe 2, so that two pipe interfaces are formed at both ends of the water pipe 2, and one of the pipe interfaces is connected to the outer flow channel 22 and one of the inner flow channel 21 sections, and the other pipe interface is connected to the other inner flow channel 21 section.

[0050] Therefore, this embodiment integrates three flow channels into the same water pipe 2, which not only reduces the number of pipes in the waterway plate assembly, but also reduces the number of pipe interfaces, making the connection between the waterway plate 1 and the body 4 of the water purifier 3 more convenient.

[0051] Furthermore, the second water guide hole 12 and the third water guide hole 13 are arranged at intervals along the axial direction of the water guide pipe 2 .

[0052] Specifically, the second water guide hole 12 and the third water guide hole 13 have a connecting joint at the second end 17 of the waterway plate 1, the connecting joint extends along the axial direction of the water guide hole, and the connecting joint passes through one side of the water guide pipe 2 along the radial direction of the water guide pipe 2 and is connected to the inner flow channel 21 or the outer flow channel 22.

[0053] Since the first inner flow channel section 23 and the second inner flow channel section 24 are arranged along the axial direction of the water pipe 2, the second water guide hole 12 and the third water guide hole 13 are arranged at intervals along the axial direction of the water pipe 2 to facilitate the second water guide hole 12 and the third water guide hole 13 to be connected to the first inner flow channel section 23 and the second inner flow channel section 24 respectively, and the extension length of the connecting joint on the water guide hole can be shortened.

[0054] In addition, see Figure 2 The first water guide hole 11 and the second water guide hole 12 or the third water guide hole 13 are staggered in the radial direction of the water guide pipe 2 so that the connecting joint on the first water guide hole 11 can be connected to the outer flow channel 22 located radially outside the water guide pipe 2.

[0055] Further, see Figure 2 The water conduit 2 includes an outer pipe 25 and an inner pipe 26, and the outer pipe 25 is sleeved on the outer periphery of the inner pipe 26. The inner flow channel 21 is located inside the inner pipe 26, and the outer flow channel 22 is located between the outer pipe 25 and the inner pipe 26.

[0056] More specifically, the inner pipe 26 includes a first inner pipe section and a second inner pipe section which are arranged axially along the water pipe 2, and the first inner pipe section and the second inner pipe section are isolated from each other.

[0057] On the basis of this structure, the connecting joint on the first water guide hole 11 passes through one side of the outer pipe 25, so that the first water guide hole 11 is connected with the outer flow channel 22; the connecting joints on the second water guide hole 12 and the third water guide hole 13 first pass through one side of the outer pipe 25, and then pass through one side of the first inner pipe section and the second inner pipe section respectively, so that the second water guide hole 12 and the third water guide hole 13 are connected with the first inner flow channel section 23 and the second inner flow channel section 24 respectively.

[0058] Thus, the clean water and waste water produced by the filter element 5 can be introduced into the first inner pipe section and the second inner pipe section through the second water guide hole 12 and the third water guide hole 13 respectively, and then flow to the two ends of the water guide pipe 2 respectively, and flow into the pipe of the body 4 through the pipe interface.

[0059] A partition may be provided in the middle of the inner pipe 26 to separate the inner pipe 26 so that the inner pipe 26 extends from both sides of the partition toward the two ends of the water guide pipe 2 to form a first inner flow channel section 23 and a second inner flow channel section 24 respectively.

[0060] For further information, see Figure 5 The two ends of the water conduit 2 are respectively provided with a first connecting piece 27 and a second connecting piece 28, wherein one end of the first connecting piece 27 is connected to the first inner flow channel or the first inner flow channel section 23, and the other end of the first connecting piece 27 is provided with a water pipe interface 29. In addition, one end of the second connecting piece 28 is connected to the second inner flow channel or the second inner flow channel section 24 and the outer flow channel 22, and the other end of the second connecting piece 28 is provided with two water pipe interfaces 29.

[0061] On the basis of this structure, a flow channel is provided inside the first connecting piece 27, and two flow channels are provided inside the second connecting piece 28, and the flow channels are connected to the flow channel in the water pipe 2 and the water pipe interface 29 respectively. Among them, the water pipe interface 29 is plugged and connected with the pipeline on the body 4. When in use, the raw water is pressurized by the pump body and is introduced into the filter element 5 in sequence from the water inlet pipeline of the body 4-a water pipe interface 29 of the second connecting piece 28-a flow channel in the second connecting piece 28-the outer flow channel 22 of the water pipe 2-the first water guide hole 11, and the clean water produced by the filter element 5 is discharged in sequence from the second water guide hole 12-the first inner flow channel section 23 of the water pipe 2-the flow channel in the first connecting piece 27-the water pipe interface 29 of the first connecting piece 27-the water outlet pipeline of the body 4.

[0062] The first connecting piece 27 and the second connecting piece 28 are both elbow pipe sections, which can connect the water pipe 2 with the pipeline on the body 4 and can change the direction of the pipeline.

[0063] Thus, three water paths are integrated into one water pipe 2, simplifying the pipeline setting of the waterway plate assembly; the three water paths are introduced or exported into the pipeline of the machine body 4 via two connecting pieces at both ends of the water pipe 2, simplifying the connection between the waterway plate assembly and the machine body 4, and preventing the problem of loose interfaces from occurring.

[0064] Further, see Figure 3 A 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 purifier 3, see Figure 6 and Figure 7 The water purifier 3 specifically includes a body 4, a filter element 5, and a waterway plate assembly with internal and external flow channels in the first embodiment. The waterway plate assembly is rotatably connected to the body 4 through the water guide pipe 2. Figure 4The 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 inner flow channel 21 and the outer 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 purifier 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 through the water pipe 2. Specifically, a plurality of pipes are provided on the body 4 of the water purifier 3, and the inner flow channel 21 and the outer flow channel 22 of the water pipe 2 can be respectively connected to at least two pipes of the body 4 through connecting pieces at both ends to realize waterway connection between the waterway plate assembly and the body 4.

[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 inner flow channel 21 and the outer 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 after the filter element 5 is inserted into the water guide hole.

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

[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 automatically 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 machine 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. Therefore, the water purifier 3 can complete the replacement of the filter element 5 through a simple structure and operation.

[0081] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
