[0051] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0052] Reference below Figure 1-Figure 16 The waterway plate assembly 100 according to an embodiment of the present invention is described. The waterway plate assembly 100 can be applied to a water purification device S, and can be formed with a waterway, which can be used to connect a filter element so that the filter element filters tap water to obtain pure water.

[0053] like Fig.10 As shown, the waterway plate assembly 100 includes: a main waterway plate 10, a transfer waterway plate 20 and an extended waterway plate 30, that is, the waterway plate assembly 100 can be mainly composed of the main waterway plate 10, the transfer waterway plate 20 and the extended waterway plate 30, wherein the main waterway plate 10 is the main waterway plate of the waterway plate assembly 100, or in other words, it is the basic waterway plate of the waterway plate assembly 100, and the transfer waterway plate 20 mainly plays a role of transfer, so that when the user replaces the required filter element as needed, the transfer waterway plate 20 can ensure that the replaced required filter element can be connected to the corresponding waterway, and the extended waterway plate 30 mainly plays a role of expansion, so that the number of filter elements that can be connected to the waterway plate assembly 100 can be increased. For example, the extended waterway plate 30 can add at least one filter element. By adding at least one filter element, tap water can be filtered through at least one more layer, which can further improve the quality of pure water, and can improve the taste of pure water, and can also meet the user's demand for water purification equipment S. The extended waterway plate 30 is different from the main waterway plate 10 , so the extended waterway plate 30 can be set according to actual needs to increase the corresponding filter element.

[0054] The main waterway plate 10 , the transfer waterway plate 20 and the extended waterway plate 30 are all provided with waterways correspondingly, and the waterways of the three are interconnected, thus forming an integral waterway of the waterway plate assembly 100 .

[0055] Specifically, the main waterway plate 10 is formed with a main waterway and a first filter element interface group 12, wherein the main waterway may correspond to a plurality of water ports, and the plurality of water ports may be located on the same side of the main waterway plate 10, for example, Figure 3 , Figure 4 , Figure 8 and Fig.12 As shown, the main waterway may correspond to the first water inlet 141, the first water outlet 142, the second water outlet 143 and the third water outlet 144. The first water inlet 141 may be a tap water inlet, that is, the first water inlet 141 of the main waterway may be connected to a faucet or a water pipe, so that tap water may be obtained. The first water outlet 142 may be a domestic water inlet, which is mainly used to meet the water needs of life. The second water outlet 143 may be compressed water, that is, waste water, which is mainly used to discharge water containing harmful substances during filtration. The third water outlet 144 is a pure water inlet, which is mainly used to meet the daily drinking needs of users.

[0056] The main water circuits are all connected to the above-mentioned water outlets, and the main water circuits are also connected to the corresponding first filter element interface group 12, and the first filter element interface group 12 at least includes a combination of a water inlet interface and a water outlet interface of the corresponding filter element. Here, it should be noted that the number of interfaces of the first filter element interface group 12 is not limited to two, and can also be three, and when the main water circuit plate 10 is formed with multiple first filter element interface groups 12, the multiple first filter element interface groups 12 can be different, for example, one first filter element interface group 12 can have a water inlet interface and a water outlet interface, that is, a first filter element interface group 12 on the left, and another first filter element interface group 12 can have a water inlet interface and two water outlet interfaces, that is, a first filter element interface group 12 on the right, and the water output of the two water outlet interfaces is different, for example, one water outlet interface can output compressed water, that is, the water outlet interface can be connected to the second water outlet 143, and one water outlet interface can output pure water or water that is close to pure after multiple filtrations, and the water outlet interface can be connected to the third water outlet 144. In this regard, the main waterway plate 10 can reasonably set the number of the first filter element interface groups 12 and the type of the first filter element interface groups 12 according to actual conditions, so as to meet the filter element requirements.

[0057] The first filter element interface group 12 is used to install the filter element, and the first filter element 41 or the second filter element 42. Here, it should be noted that the number of interfaces of the first filter element interface group 12 is at least the same as the number of interfaces of the connected filter element. When the number of interfaces of the two is the same, for example, both are two, the water inlet interface of the first filter element interface group 12 is connected to the water inlet interface of the filter element, and the water outlet interface of the first filter element interface group 12 is connected to the water outlet interface of the filter element. When the number of interfaces of the first filter element interface group 12 is greater than the number of interfaces of the connected filter element, the extra interfaces of the first filter element interface group 12 can be provided with corresponding plugs, and the interfaces with the right number can be connected.

[0058] like Fig.11 and Fig.13 As shown, the transfer waterway plate 20 is formed with a transfer waterway and a second filter element interface group 22, and the transfer waterway is connected to the second filter element interface group 22 to transfer the required filter element, that is, the fourth filter element 44. In the production process of the water purification equipment S, the waterway plate assembly 100 can reasonably match filter elements of different models according to the user's use requirements, and the transfer waterway plate 20 mainly plays a role of transfer. In this way, when the required filter element cannot be docked and connected with the corresponding first filter element interface group 12, the transfer waterway plate 20 can play a role of transfer between the first filter element interface group 12 and the interface group of the required filter element through the transfer waterway, so that it can be docked and connected with the interface group of the required filter element through the second filter element interface group 22.

[0059] It should be noted that both the first filter element interface group 12 and the second filter element interface group 22 play the role of connecting the filter element interface group, but the first filter element interface group 12 and the second filter element interface group 22 are different, which can solve the problem of mismatch between the main waterway plate 10 and the required filter element. Moreover, through the combination of the main waterway plate 10 and the transfer waterway plate 20, the main waterway plate 10 can be standardized and modularized, which can reduce the research and development of waterway plates and production molds, reduce the production cost of the waterway plate assembly 100, and reduce the cost of the water purification equipment S. In addition, this waterway plate assembly 100 can perform corresponding waterway switching, so as to meet the different needs of users.

[0060] like Figure 10-12As shown, the extended waterway plate 30 is arranged on one side of the main waterway plate 10. For example, the extended waterway plate 30 can be arranged on one side of the length direction of the main waterway plate 10, and the length direction is the left and right direction. It can be understood that the projection of the main waterway plate 10 on the horizontal plane can be a rectangle, and the extended waterway plate 30 can be arranged on one side of its length direction, so that a plurality of water inlets, namely a water inlet and a plurality of water outlets, can be provided on the other side of the length direction of the main waterway plate 10. The extended waterway plate 30 and the main waterway plate 10 arranged in this way can be generally a long strip structure, so that the waterway plate assembly 100 can be arranged in the outer casing of the water purification equipment S more conveniently, and the arrangement of multiple filter elements in sequence can also be facilitated, thereby reducing the thickness of the outer casing, flattening the water purification equipment S, and facilitating the water purification equipment S to be fixed at a corresponding position in the room, such as hanging it on a wall in the room.

[0061] Of course, the waterway plate assembly 100 of the embodiment of the present invention is not limited to this. The extended waterway plate 30 can also be set on one side of the width direction of the main waterway plate 10, and the width direction is the front-to-back direction. This can reduce the overall length of the waterway plate assembly 100 and increase the overall width of the waterway plate assembly 100.

[0062] In addition, the number of the above-mentioned extended waterway plates 30 can be at least one, that is, the above-mentioned extended waterway plates 30 are not limited to one. For example, an extended waterway plate 30 can be further provided on the side of the extended waterway plate 30 away from the main waterway plate 10, so that the waterway plate assembly 100 can be distributed sequentially in the length direction, and the two extended waterway plates 30 are in a connected state.

[0063] like Fig.11 As shown, the expansion waterway plate 30 is formed with an expansion waterway and a third filter element interface group 32, and the expansion waterway is respectively connected with the third filter element interface group 32 and the main waterway, that is, the expansion waterway in the expansion waterway plate 30 can be connected with the main waterway, and the connection method can be direct connection or indirect connection. Direct connection means that the water passing through the main waterway will directly enter the expansion waterway, and indirect connection means that the water passing through the main waterway first passes through other components and then passes through the expansion waterway. The other components can be a pump body 200, and the pump body 200 can be a booster pump.

[0064] It can be understood that the expansion waterway plate 30 can play the role of expanding the waterway. In this way, on the basis of the fixed structure of the main waterway plate 10, the filtering function can be expanded by adding the expansion waterway plate 30, so that the waterway plate assembly 100 can have the function of adding the required functional filter element, which can improve the filtering performance of the filter element, further meet user needs, and improve water quality and taste.

[0065] In addition, the extended waterway plate 30 configured in this way can further facilitate the standardized and modular production of the main waterway plate 10 and the extended waterway plate 30, which can reduce the research and development of waterway plates and production molds, reduce the production cost of the waterway plate assembly 100, and reduce the cost of the water purification equipment S.

[0066] In addition, the adapter waterway plate 20 can not only be set on the main waterway plate 10, but also can be set on the extended waterway plate 30, so that the adapter waterway can be connected to the third filter element interface group 32. For example, when the extended waterway plate 30 can match the required filter element, the adapter waterway plate 20 can be added to the extended waterway plate 30, so that the required filter element can be effectively matched with the extended waterway plate 30 to meet the needs of users.

[0067] Therefore, according to the waterway plate assembly 100 of the embodiment of the present invention, by setting the main waterway plate 10, the transfer waterway plate 20 and the expansion waterway plate 30, it can be beneficial to the standardized and modular production of the waterway plates, which can reduce the research and development of waterway plates and production molds, can reduce the production cost of the waterway plate assembly 100, and can reduce the cost of the water purification equipment S, and the waterway plate assembly 100 arranged in this way can effectively meet the different needs of users, and through different splicing and combination methods, it can match filter elements with different functions, thereby meeting the needs of users and improving the quality and taste of pure water.

[0068] The arrangement of the transfer waterway plate 20 is described in detail below with reference to the accompanying drawings.

[0069] According to an optional embodiment of the present invention, Fig.13 and Fig.14 As shown, the projection position of the first filter element interface group 12 on the horizontal plane is different from the projection position of the corresponding second filter element interface group 22 on the horizontal plane. In other words, the first filter element interface group 12 and the second filter element interface group 22 can be arranged differently, so that when the number of interfaces of the first filter element interface group 12 and the number of interfaces of the required filter element are the same, the second filter element interface group 22 with a different position can be used to match the interface group of the filter element with the interface group of the required filter element according to user needs, thereby completing the installation of the filter element. The number of interfaces of the first filter element interface group 12 and the number of interfaces of the second filter element interface group 22 can both be two, or they can both be three.

[0070] Specifically, the first filter element interface group 12 has three first interfaces 16, the three first interfaces 16 are one water inlet interface and two water outlet interfaces, and the two water outlet interfaces are respectively a water outlet interface for compressed water and a water outlet interface for pure water. The second filter element interface group 22 has three second interfaces 25, the three second interfaces 25 are one water inlet interface and two water outlet interfaces, and the two water outlet interfaces are respectively a water outlet interface for compressed water and a water outlet interface for pure water. Thus, the three first interfaces 16 and the three second interfaces 25 can be connected one by one through the three transfer channels 21 of the transfer waterway.

[0071] like Figure 2 and Fig.11 As shown, the centers of the three first interfaces 16 are connected in sequence to form a first triangle, and the centers of the three second interfaces 25 are connected in sequence to form a second triangle. When the first filter element interface group 12 can be used to install a small-diameter filter element, but a large-diameter filter element needs to be installed at the first filter element interface group 12 according to user needs, the projection of the first triangle on the horizontal plane surrounds the inner side of the projection of the second triangle on the horizontal plane. When the first filter element interface group 12 can be used to install a large-diameter filter element, but a small-diameter filter element needs to be installed at the first filter element interface group 12 according to user needs, the projection of the second triangle on the horizontal plane surrounds the inner side of the projection of the first triangle on the horizontal plane. In this way, the modular design of the waterway plate assembly 100 can be achieved, and different filter elements can be replaced according to different user needs, so that users have multiple choices, and the use function of the waterway plate assembly 100 is improved to better meet user needs.

[0072] It should be noted that when the adapter waterway plate 20 has been installed on the main waterway plate 10, if the adapter waterway plate 20 cannot be installed, the first filter element interface group 12 of the main waterway plate 10 can be connected to the interface group of the required filter element by disassembling the adapter waterway plate 20.

[0073] Among them, the first triangle and the second triangle have the same shape, that is, the various angles of the first triangle and the various angles of the second triangle are the same, the first triangle and the second triangle can be equilateral triangles, that is, the angle between two adjacent interfaces of the three interfaces of the first filter element interface group 12 is 120°, and the angle between two adjacent interfaces of the three interfaces of the second filter element interface group 22 is 120°. The first filter element interface group 12 and the second filter element interface group 22 set in this way can avoid mutual interference between adjacent interfaces, and can also ensure the structural reliability of the main water circuit plate 10 and the adapter water circuit plate 20.

[0074] When there are two interfaces in the first filter element interface group 12, the two interfaces are respectively a water inlet interface and a water outlet interface, and the angle between the water inlet interface and the water outlet interface is 120° on one side and 240° on the other side.

[0075] Therefore, by setting three reasonable first interfaces 16 and three second interfaces 25, the interface group position of the waterway plate assembly 100 can be reasonably changed so that it can match the required filter element and meet the connection requirements of the currently required filter element.

[0076] Alternatively, if Fig.14 As shown, the transfer waterway includes: a plurality of transfer channels 21, the transfer channel 21 includes: a first vertical section 211, a transfer section 212 and a second vertical section 213, the transfer section 212 is connected between the first vertical section 211 and the second vertical section 213 and has an angle with the first vertical section 211, the lower end of the first vertical section 211 is connected to the interface of the first filter element interface group 12, and the upper end of the second vertical section 213 is connected to the interface of the second filter element interface group 22. By setting the transfer section 212, the position of the second vertical section 213 relative to the first vertical section 211 can be changed, so that the interface of the first filter element interface group 12 and the interface of the second filter element interface group 22 can be connected, and the interface position of the second filter element interface group 22 relative to the interface of the first filter element interface group 12 can be changed, so that the required filter element can be effectively connected, which can meet the needs of users.

[0077] Among them, the transfer section 212 is a horizontal section, and the transfer section 212 extends radially along the second filter element interface group 22. That is to say, the transfer section 212 is vertically arranged relative to the first vertical section 211 and the second vertical section 213, but its connection with the first vertical section 211 and its connection with the second vertical section 213 can be set to an arc structure, which can facilitate the flow of water. Moreover, by setting the transfer section 212 as a horizontal section, it can be convenient for the second filter element interface group 22 to be synchronously expanded or reduced in the radial direction relative to the first filter element interface group 12, so as to match the interface group of the required filter element. For example, when the transfer section 212 extends radially inward from the first vertical section 211, the transfer waterway plate 20 can be used to connect and connect small-diameter filter elements, and when the transfer section 212 extends radially outward from the first vertical section 211, the transfer waterway plate 20 can be used to connect and connect large-diameter filter elements. The transfer section 212 configured in this way can be beneficial to the formation of the transfer channel 21, and can be beneficial to the effective transfer of the transfer channel 21, and can ensure the normal flow of water.

[0078] According to another embodiment of the present invention, the number of interfaces of the first filter element interface group 12 is different from the number of interfaces of the second filter element interface group 22. It can be understood that when the number of interfaces of the first filter element interface group 12 is different from the number of interfaces of the interface group of the required filter element, it can be connected to the interface group of the required filter element by setting a transfer water circuit plate 20 on the main water circuit plate 10. In this way, the required filter element can be effectively connected, the water purification effect of the water purification equipment S can be improved, and the quality and taste of the pure water can be improved.

[0079] Optionally, the number of interfaces of the first filter element interface group 12 is greater than the number of interfaces of the second filter element interface group 22, and at least one interface of the first filter element interface group 12 is provided with a plug. For example, the number of first interfaces 16 of the first filter element interface group 12 on the main waterway plate 10 is three, and when the required filter element has only two interfaces, the transfer waterway plate 20 may have two second interfaces 25, one of the three transfer channels 21 is closed, and one of the first interfaces 16 is blocked by a plug, and the other two transfer channels 21 are connected between the first interface 16 and the second interface 25.

[0080] The first filter element interface group 12 and the second filter element interface group 22 configured in this way can effectively connect the required filter elements, and can avoid water leakage problems in the waterway, and can further ensure the structural reliability of the waterway plate assembly 100 and the reliability of the water purification equipment S.

[0081] Alternatively, the number of interfaces of the first filter element interface group 12 is less than the number of interfaces of the second filter element interface group 22, and the transfer channel 21 of the transfer waterway is provided with at least two branch waterways, and at least two branch waterways are connected to the interface of the same first filter element interface group 12. In other words, the two branch waterways can use a common interface, so that the interface of the required filter element can be matched.

[0082] For example, the number of first interfaces 16 of the first filter element interface group 12 is two. When the required filter element has three interfaces, the adapter waterway plate 20 can have three second interfaces 25, and one of the adapter channels 21 can form two branch channels to connect the two second interfaces 25, so as to effectively connect the required filter element.

[0083] Therefore, when installing the adapter waterway plate 20, the adapter channels 21 of the adapter waterway can be increased or decreased, so as to adapt to different filter elements, effectively connect and connect the required filter elements, and meet the needs of users.

[0084] According to another embodiment of the present invention, the main water circuit board 10 is provided with a first filter element installation groove 15 at a position corresponding to the first filter element interface group 12, and the transfer water circuit board 20 is provided with a second filter element installation groove 27 at a position corresponding to the second filter element interface group 22. The first filter element installation groove 15 and the second filter element installation groove 27 have different sizes, or the first filter element installation groove 15 and the second filter element installation groove 27 have different shapes, so as to transfer the required filter element. It can be understood that the filter element includes a filter cartridge and a filter head, and the filter head is installed at the end of the filter cartridge. The filter head size or shape of some filter elements is different, which will cause the first filter element installation groove 15 to be unable to directly install the filter element. The transfer water circuit board 20 can play a transfer role, so that it can be effectively transferred to the main water circuit board 10, which can meet the user's water demand.

[0085] In some examples of the present invention, Fig.16 As shown, the water purification device S also includes: a skeleton 45 and a support frame 46. The diameter of the first filter element installation groove 15 is larger than the diameter of the second filter element installation groove 27. The skeleton 45 is arranged on one side of the main waterway plate 10. The support frame 46 is supported inside the skeleton 45 and defines a filter element installation space. The filter element is accommodated in the filter element installation space. The support frame 46 arranged in this way can play a supporting role. In this way, when a small-diameter filter element is installed on the transfer waterway plate 20, it can be supported on the outside of the small-diameter filter element, which can avoid the problem of misalignment of the small-diameter filter element installation and ensure the installation reliability of the small-diameter filter element.

[0086] Furthermore, if Fig.16 As shown, the support frame 46 includes: a sleeve 461, a base 462, a middle support sheet 463 and an upper support sheet 464. The base 462, the middle support sheet 463 and the upper support sheet 464 are all arranged on the sleeve 461 and arranged in sequence. The base 462 is arranged on the transfer waterway plate, the middle support sheet 463 and the upper support sheet 464 are supported on the inner side of the skeleton 45, and the sleeve 461 defines the filter element installation space. The base 462 can ensure the installation stability of the support frame 46, and the middle support sheet 463 and the upper support sheet 464 can play the role of layered support, which can further improve the installation reliability of the small diameter filter element.

[0087] According to another embodiment of the present invention, the interface structure of the first filter element interface group 12 is different from the interface structure of the second filter element interface group 22. It is understandable that the interface structures at some filter heads are also different to a certain extent, and interfaces with different structures cannot be directly connected. By setting the transfer waterway plate 20, the transfer can be effectively completed, and the reliability between the two can be guaranteed.

[0088] Optionally, the interface of the first filter element interface group 12 is one of a threaded interface and a plug-in interface, and the interface of the second filter element interface group 22 is one of a threaded interface and a plug-in interface. For example, when the first filter element interface group 12 is a threaded interface and the interface of the filter element is a plug-in interface, the bottom of the adapter waterway plate 20 can be threadedly connected to the threaded interface, and the plug-in interface of the second filter element interface group 22 can be plug-connected to the plug-in interface of the filter element, which can solve the problem that the first filter element interface group 12 cannot be connected to the filter element.

[0089] In addition, the interface of the first filter element interface group 12 and the interface of the second filter element interface group 22 can be of the same type, but the sizes of the sockets are different. For example, when the first filter element interface group 12 is a threaded interface and the interface of the filter element is also a threaded interface, but the thread sizes of the threaded interfaces are different, the bottom of the adapter waterway plate 20 can be threadedly connected to the threaded interface, and the threaded interface of the second filter element interface group 22 can be threadedly connected to the threaded interface of the filter element, so that the first filter element interface group 12 can also be connected to the filter element.

[0090] The arrangement of the extended waterway plate 30 is described in detail below.

[0091] like Fig.13 and Fig.15 As shown, the expansion waterway plate 30 is detachably arranged on one side of the main waterway plate 10, that is, the installation method of the expansion waterway plate 30 is a detachable installation method, which can facilitate the installation and removal of the expansion waterway plate 30. In this way, when the expansion waterway plate 30 needs to be installed, the expansion waterway plate 30 can be installed on one side of the main waterway plate 10, and when the expansion waterway plate 30 is not needed, the expansion waterway plate 30 can be removed from one side of the main waterway plate 10. The expansion waterway plate 30 arranged in this way can be conducive to the standardized and modular production and manufacturing of the waterway plate assembly 100, and can be conducive to docking and connecting the required filter element.

[0092] Optionally, the expansion waterway plate 30 is clamped to one side of the main waterway plate 10 through a clamping structure. The clamping method is simple and convenient, and can ensure the reliability of the installation of the expansion waterway plate 30 on the side of the main waterway plate 10, and it can also facilitate the disassembly of the expansion waterway plate 30 and avoid its disassembly affecting the main waterway plate 10.

[0093] Among them, Fig.13 and Fig.15 As shown, a first clamping portion 13 is provided on one side edge of the main waterway plate 10, and a second clamping portion 33 is provided on one side edge of the extended waterway plate 30. The first clamping portion 13 and the second clamping portion 33 are clamped together, and the combination of the first clamping portion 13 and the second clamping portion 33 constitutes a clamping structure. By providing the first clamping portion 13 on the main waterway plate 10 and the second clamping portion 33 on the extended waterway plate 30, the clamping cooperation of the first clamping portion 13 and the second clamping portion 33 can realize the fixed connection between the extended waterway plate 30 and the main waterway plate 10, so that the modular design of the waterway plate assembly 100 can be further realized.

[0094] Among them, the first clamping part 13 is one of the slot and the buckle, and the second clamping part 33 is the other of the slot and the buckle. With such a configuration, the expansion waterway plate 30 and the main waterway plate 10 can be connected through the cooperation of the hook and the slot, and the buckle and the slot are detachably connected, which is convenient for subsequent replacement or maintenance.

[0095] Furthermore, if Fig.13 and Fig.15As shown, a first guide portion 132 is provided on one side edge of the main waterway plate 10, and a second guide portion 34 is provided on one side edge of the expansion waterway plate 30, and the first guide portion 132 and the second guide portion 34 are guided and matched. By providing the first guide portion 132 on one side of the main waterway plate 10 and the second guide portion 34 on one side edge of the expansion waterway plate 30, when the first guide portion 132 and the second guide portion 34 are guided and matched, it can play a role of installation guide, which can facilitate the assembly between the expansion waterway plate 30 and the main waterway plate 10, and can also further improve the installation reliability between the two.

[0096] Specifically, Fig.13 and Fig.15 As shown, there are two first guides 132 and two second guides 34, and the first guides 132 and the second guides 34 correspond to each other. The two first guides 132 are located on both sides of the first clamping portion 13, and the two second guides 34 are located on both sides of the second clamping portion 33. In this way, the first guides 132 are arranged on both sides of the first connecting portion, and the second guides 34 are arranged on both sides of the second connecting portion, which can facilitate the connection between the extended waterway plate 30 and the main waterway plate 10, and the force is uniform after the extended waterway plate 30 and the main waterway plate 10 are connected, which can better ensure the connection reliability between the extended waterway plate 30 and the main waterway plate 10.

[0097] Further, the first guide portion 132 is one of the guide rail and the guide block, and the second guide portion 34 is the other of the guide rail and the guide block. The use of the guide rail and the guide block can not only facilitate the connection between the expansion waterway plate 30 and the main waterway plate 10, but also further improve the connection strength between the expansion waterway plate 30 and the main waterway plate 10.

[0098] Alternatively, the expansion waterway plate 30 is fixed to one side of the main waterway plate 10 by fasteners. In this way, the expansion waterway plate 30 can be easily connected and disassembled from the main waterway plate 10, and the expansion waterway plate 30 is installed on one side of the main waterway plate 10 to reasonably utilize the lateral space of the main waterway plate 10.

[0099] The arrangement of the transfer waterway plate 20 is described in detail below.

[0100] like Fig.13 and Fig.14As shown, the transfer waterway plate 20 is detachably mounted on the main waterway plate 10. That is, the installation method of the transfer waterway plate 20 is a detachable installation method, which can facilitate the installation and removal of the transfer waterway plate 20. In this way, when the transfer waterway plate 20 is required, the transfer waterway plate 20 can be installed on the main waterway plate 10, and when the transfer waterway plate 20 is not required, the transfer waterway plate 20 can be removed from the main waterway plate 10. The transfer waterway plate 20 arranged in this way can be conducive to the standardized and modular production and manufacturing of the waterway plate assembly 100, and can be conducive to docking and connecting the required filter element.

[0101] Optionally, the transfer waterway plate 20 is connected to the main waterway plate 10 via a clamping structure. By providing the clamping structure, the transfer waterway plate 20 can be effectively connected to the main waterway plate 10, which can help ensure the installation reliability between the transfer waterway plate 20 and the main waterway plate 10, and can also facilitate the docking and communication between the first filter element interface group 12 and the transfer waterway.

[0102] The snap-fit ​​structure may include a snap buckle and a snap slot, one of the snap buckle and the snap slot is disposed on the transfer waterway plate 20 and the other is disposed on the main waterway plate 10 .

[0103] Alternatively, the transfer waterway plate 20 is fixed to the main waterway plate 10 by fasteners. This arrangement can facilitate the connection and disassembly of the transfer waterway plate 20 and the main waterway plate 10, and can ensure the installation reliability of the transfer waterway plate 20 on the main waterway plate 10.

[0104] Furthermore, if Fig.11 and Fig.13 As shown, the transfer waterway plate 20 is provided with an outer mounting hole 23 and an inner mounting hole 24. The inner mounting hole 24 is adjacent to the center of the transfer waterway plate 20. For example, it can be directly set at the center. There are multiple outer mounting holes 23, and the multiple outer mounting holes 23 surround the outer periphery of the transfer waterway plate 20. The main waterway plate 10 is provided with mounting holes or mounting columns corresponding to the outer mounting holes 23 and the inner mounting holes 24. There are multiple fasteners, and the multiple fasteners correspond to the outer mounting holes 23 and the inner mounting holes 24. The multiple outer mounting holes 23 can play a role in external mounting and fixing, and the inner mounting holes 24 can play a role in aligning the centers of the first filter element interface group 12 and the second filter element interface group 22, which can further ensure the docking and communication between the first filter element interface group 12 and the transfer waterway, and can ensure the docking and communication between the second filter element interface group 22 and the interface group of the required filter element. The outer mounting holes 23 and the inner mounting holes 24 arranged in this way can better ensure the installation accuracy of the adapter waterway plate 20 on the main waterway plate 10, and can ensure its docking and communication with the filter element.

[0105] Specifically, Fig.10 and Fig.11As shown, there are two groups of first filter element interface groups 12, that is, the main waterway plate 10 can be used to install two filter elements, the first water inlet 141 is connected to the main waterway, the first water outlet 142 is selectively connected to the water outlet interface of a group of first filter element interface groups 12, and the group of first filter element interface groups 12 can be used to dock and connect the first filter element 41, and the second water outlet 143 is selectively connected to the water outlet interface of another group of first filter element interface groups 12, and the other group of first filter element interface groups 12 can be used to dock and connect the first filter element 41. The second filter element 42, the third water outlet 144 is connected to the water outlet interface of the third filter element interface group 32, the third filter element interface group 32 can be used to connect the third filter element 43, the transfer waterway corresponds to any group of first filter element interface groups 12, the transfer waterway plate 20 can be used to connect the fourth filter element 44, when the transfer waterway plate 20 is installed in one group of first filter element interface groups 12, it replaces the first filter element 41, when the transfer waterway plate 20 is installed in another group of first filter element interface groups 12, it replaces the second filter element 42. The waterway plate assembly 100 set in this way can select a reasonable setting position of the transfer waterway plate 20 as needed, so that the required filter element can be installed, which can meet the needs of users.

[0106] Specifically, Figure 3 , Figure 8 and Fig.12 As shown, a first control valve 121 is also connected to the water outlet interface of a group of first filter cartridge interface groups 12, and a second control valve 122 is also connected to the water outlet interface of another group of first filter cartridge interface groups 12. Both the first control valve 121 and the second control valve 122 can be solenoid valves. The water outlet of a group of first filter cartridge interface groups 12 can be controlled by the first control valve 121. For example, the water outlet interface of a group of first filter cartridge interface groups 12 can be connected to the first water outlet 142, or can be connected to the water inlet interface of another group of first filter cartridge interface groups 12. The connection between the two can be through a pipeline connection. The water outlet of another group of first filter cartridge interface groups 12 can be controlled by the second control valve 122. For example, the water outlet interface of another group of first filter cartridge interface groups 12 can be connected to the second water outlet 143, so that compressed water can be discharged reasonably. Such a setting can realize the connection of multiple waterways inside the waterway plate assembly 100, thereby improving the selectivity of users when using water. The docking interface between the extended waterway plate 30 and the main waterway plate 10 can be connected by a pipeline.

[0107] like Figure 2 and Figure 7As shown, the main water circuit plate 10 is provided with a first filter element mounting groove 15, for example, one, for example, two, and for example, more than two. That is to say, the main water circuit plate 10 can be provided with a reasonable number of first filter element mounting grooves 15. The transfer water circuit plate 20 is installed at at least one first filter element mounting groove 15, wherein at least a portion of the transfer water circuit plate 20 is accommodated in the first filter element mounting groove 15. By providing a plurality of first filter element mounting grooves 15 on the main water circuit plate 10, the transfer water circuit plate 20 can be installed at the position of the first filter element mounting groove 15, and the corresponding filter element can be installed at the first filter element mounting groove 15, thereby improving the connection stability between the transfer water circuit plate 20 and the main water circuit plate 10 and the installation reliability of the filter element, avoiding the unstable connection of the transfer water circuit plate 20, causing the filter element to fall off, and further ensuring the reliability of the water purification equipment S.

[0108] On this basis, the transfer water circuit plate 20 also includes: a mounting plate 26 and a second filter element mounting groove 27, the second filter element mounting groove 27 surrounds the outer side of the second filter element interface group 22, the mounting plate 26 is arranged on the outer side of the second filter element mounting groove 27, and the mounting plate 26 is fixed to the surface of the main water circuit plate 10. In other words, the transfer water circuit plate 20 is also provided with a second filter element mounting groove 27, and the second filter element mounting groove 27 is surrounded on the outer side of the second filter element interface group 22, which can facilitate its docking and connection with the fourth filter element 44. The setting of the mounting plate 26 can make it close to the surface of the main water circuit plate 10, which can ensure the reliability of its installation on the main water circuit plate 10. Among them, the mounting plate 26 is detachable relative to the main water circuit plate 10, so that the transfer water circuit plate 20 can be detachable relative to the main water circuit plate 10. Moreover, the above-mentioned external mounting holes 23 are distributed on the outer periphery of the mounting plate 26.

[0109] In addition, a sealing ring 28 is provided between the first filter element interface group 12 and the transfer channel 21 of the transfer waterway. The sealing ring 28 can play a sealing role, can avoid the problem of water leakage in the waterway here, can further ensure the sealing reliability of the waterway plate assembly 100.

[0110] Optionally, the main waterway plate 10, the expansion waterway plate 30 and the transfer waterway plate 20 can all be an integrally formed structure, that is, the above three waterway plates can be manufactured separately and are an integrally formed structure. The waterway plate structure arranged in this way is simple and reliable, and the manufacturing cost is low.

[0111] The water purification device S according to the embodiment of the present invention comprises the waterway plate assembly 100 and the filter element of the above embodiment, and the filter element is installed at the corresponding filter element interface group. The water purification device S configured in this way can realize the standardized and modular production and manufacturing of the waterway plate assembly 100, which can improve the water purification effect of the water purification device S and enable the water purification device S to better meet the needs of users. Figure 4As shown, the water purification device S further includes a frame 45 , which is disposed on the main waterway plate 10 , and the first filter element 41 and the second filter element 42 are respectively installed in the frame 45 .

[0112] Among them, the filter element arranged on the main waterway plate 10 is a composite filter element, which can be a composite filter element of PP (polypropylene) and activated carbon, or a composite filter element of reverse osmosis and activated carbon. The filter element arranged on the transfer waterway plate 20 is at least one of a reverse osmosis filter element, an ultrafiltration filter element, and a nanofiltration filter element, and the filter element arranged on the expansion waterway plate 30 is a post-activated carbon filter element or a post-composite activated carbon filter element. In other words, the first filter element 41 can be a composite filter element of two filter elements, the second filter element 42 can be a composite filter element of two filter elements, the third filter element 43 can be a post-activated carbon filter element or a post-composite activated carbon filter element, and the fourth filter element 44 can be at least one of a reverse osmosis filter element, an ultrafiltration filter element, and a nanofiltration filter element. The multiple filter elements arranged in this way can effectively filter impurities in the water by combining them, improve the quality of pure water, and meet user needs.

[0113] like Figure 1 , Figure 6 and Fig.10 As shown, the water purification device S also includes: a pump body 200, which is connected to the main waterway and the transfer waterway, and the pump body 200 can provide power to ensure that water can flow smoothly in the waterway. The pump body 200 can be a booster pump.

[0114] The actual splicing and assembly method of multiple waterway plate assemblies 100 will be described in detail below with reference to the accompanying drawings.

[0115] Main waterway plate 10: Figure 1-Figure 5As shown, the waterway plate assembly 100 is only provided with the main waterway plate 10. Water enters the main waterway plate 10 from the first water inlet 141 (i.e., the tap water port), and the water enters a first filter element 41 through a first interface 16 (i.e., the water inlet interface) of one group of first filter element interface groups 12 for filtration, and the filtered water is selectively discharged from another first interface 16 (i.e., the water outlet interface) to the first water outlet 142 (i.e., the domestic water outlet). Here, it is necessary to make a selection according to the actual use of the user. When the user needs domestic water, the user can choose to directly access the water from the first water outlet 142. Alternatively, the filtered water enters the first control valve 121, then flows into the pump body 200 through the fourth interface 51 and the fifth interface 52, and after being pressurized by the pump body 200, flows into a first interface 16 (i.e., water inlet interface) of another first filter element interface group 12 through the sixth interface 53 and the seventh interface 54, and then enters the second filter element 42 for filtration, and the concentrated water after filtration flows into the second control valve 122, and then flows out from the second water outlet 143 (i.e., compressed water outlet); the filtered pure water flows out from the third water outlet 144 (i.e., pure water outlet) through the eighth interface 55 and the ninth interface 56. A pipeline may be connected between the two connected interfaces.

The filtered pure water flows out from the third water outlet 144 (i.e., the pure water outlet) through the eleventh interface 58 and the ninth interface 56.

[0118] The first filter element 41 is a composite filter element of PP and activated carbon, the second filter element 42 is a reverse osmosis filter element, and the third filter element 43 is a post-activated carbon filter element.

Alternatively, the filtered water enters the first control valve 121, and then flows into the pump body 200 through the fourth interface 51 and the fifth interface 52. After being pressurized by the pump body 200, it flows into a first interface 16 (i.e., the water inlet interface) of another first filter element interface group 12 through the sixth interface 53 and the seventh interface 54. The filtered water enters the fourth filter element 44 from a second interface 25 (i.e., the water inlet interface) on the transfer water circuit board 20 for filtration. The concentrated water after filtering again passes through another second interface 25 (i.e., the water outlet interface) and another first interface. 16 (i.e., the water outlet interface) flows into the second control valve 122, and then flows out from the second water outlet 143 (i.e., the compressed water outlet); the purified water after filtering again passes through another second interface 25 (i.e., the water outlet interface) and another first interface 16 (i.e., the water outlet interface).

Here, it is necessary to make a selection according to the actual use of the user. When the user needs domestic water, he can choose to directly access the water from the first water outlet 142. Alternatively, the filtered water enters the first control valve 121, then flows into the pump body 200 through the fourth interface 51 and the fifth interface 52, and after being pressurized by the pump body 200, flows into a first interface 16 (i.e., the water inlet interface) of another first filter element interface group 12 through the sixth interface 53 and the seventh interface 54, and the filtered water enters the fourth filter element 44 from a second interface 25 (i.e., the water inlet interface) on the adapter water circuit plate 20 for filtration, and the concentrated water after filtering again flows into the second control valve 122 through another second interface 25 (i.e., the water outlet interface) and another first interface 16 (i.e., the water outlet interface), and then flows out from the second water outlet 143 (i.e., the compressed water outlet); the pure water after filtering again passes through another second interface 25 (i.e., the water outlet interface) and another first interface 16 (i.e., the water outlet interface), and the pure water after filtering again flows out from the third water outlet 144 (i.e., the pure water outlet) through the eighth interface 55 and the ninth interface 56.
