Specifically, the main waterway plate 10 is formed with a main waterway and a first cartridge interface group 12, wherein the main waterway may correspond to a plurality of water ports, the plurality of water ports may be located on the same side of the main waterway plate 10, for example, as shown in fig. 3, 4, 8 and 12, the main waterway may correspond to a first water inlet 141, a first water outlet 142, a second water outlet 143 and a third water outlet 144, and the first water inlet 141 may be a tap water inlet, that is, the first water inlet 141 of the main waterway may be communicated with a tap or a tap water pipe, so as to obtain tap water. The first water outlet 142 may be a domestic water outlet mainly for satisfying water required for life, the second water outlet 143 may be compressed water, i.e., wastewater, mainly for discharging water containing harmful substances upon filtering, and the third water outlet 144 may be a purified water outlet mainly for satisfying daily reference of users.

The main water path is communicated with the water gap, the main water path is connected with a corresponding first filter element interface group 12, and the first filter element interface group 12 at least comprises a combination of a water inlet interface and a water outlet interface corresponding to the filter elements. Here, it should be noted that the number of the first filter element interface set 12 is not limited to two, but may also be three, and when the main waterway plate 10 is formed with a plurality of first filter element interface sets 12, the plurality of first filter element interface sets 12 may be different, for example, one first filter element interface set 12 may have one water inlet interface and one water outlet interface, that is, one first filter element interface set 12 on the left side, and another first filter element interface set 12 may have one water inlet interface and two water outlet interfaces, that is, one first filter element interface set 12 on the right side, and the two water outlet interfaces have different water outlets, for example, one water outlet interface may have a compressed water outlet, that is, the water outlet interface may be communicated with the second water outlet 143, one water outlet interface may be purified water or water that is nearly purified by filtering for multiple times, and the water outlet interface may be communicated with the third water outlet 144. To this end, the main waterway plate 10 can reasonably set the number of the first filter element interface groups 12 and the types of the first filter element interface groups 12 according to actual situations, thereby satisfying the filter element requirements.

First cartridge interface group 12 is configured to receive a cartridge, either first cartridge 41 or second cartridge 42. Here, it should be noted that the number of the joints of the first filter element joint set 12 is at least the same as the number of the connected filter element joints, and when the number of the joints of the first filter element joint set 12 is the same as that of the connected filter element joints, for example, both of the first filter element joint set and the connected filter element joints are two, the water inlet joint of the first filter element joint set 12 is communicated with the water inlet joint of the filter element, and the water outlet joint of the first filter element joint set 12 is communicated with the. When the number of the interfaces of the first filter element interface group 12 is greater than the number of the connected filter element interfaces, the extra interfaces of the first filter element interface group 12 can be correspondingly provided with plugs, and the interfaces with the rigid number can be butted.

As shown in fig. 11 and 13, the adapting waterway plate 20 is formed with an adapting waterway and a second cartridge interface set 22, and the adapting waterway is communicated with the second cartridge interface set 22 to adapt to a required cartridge, i.e., a fourth cartridge 44. Wherein, water purification unit S is in the manufacturing process, water route board subassembly 100 can rationally match the filter core of different models according to user' S user demand, switching water route board 20 mainly plays the effect of switching, when required filter core can not dock the intercommunication with the first filter core interface group 12 that corresponds like this, switching water route board 20 can play the switching effect between the interface group of first filter core interface group 12 and required filter core through the switching water route, can dock the intercommunication through the interface group of second filter core interface group 22 with the required filter core like this.

It should be noted that, the first filter cartridge interface group 12 and the second filter cartridge interface group 22 both function to connect the filter cartridge interface groups, but the first filter cartridge interface group 12 and the second filter cartridge interface group 22 are different, so that the problem of mismatch between the main waterway plate 10 and the required filter cartridge can be solved. Moreover, through the combination of the main waterway plate 10 and the transit waterway plate 20, the main waterway plate 10 can be standardized and modularly produced, so that the development of waterway plates and production molds can be reduced, the production cost of the waterway plate assembly 100 can be reduced, and the cost of the water purifying apparatus S can be reduced. In addition, the waterway plate assembly 100 can perform corresponding waterway switching, thereby satisfying different requirements of users.

As shown in fig. 10-12, the expanded water channel plate 30 is disposed on one side of the main water channel plate 10, for example, the expanded water channel plate 30 may be disposed on one side of the main water channel plate 10 in the length direction, which is the left-right direction, it can be understood that the projection of the main water channel plate 10 on the horizontal plane may be rectangular, the expanded water channel plate 30 may be disposed on one side of the main water channel plate in the length direction, so that the other side of the main water channel plate 10 in the length direction may be provided with a plurality of water outlets, i.e., a water inlet and a plurality of water outlets, the expanded water channel plate 30 and the main water channel plate 10 thus disposed may be substantially in a strip structure, so that the water channel plate assembly 100 may be conveniently disposed in the housing of the water purifying apparatus S, and a plurality of filter elements may be conveniently arranged in sequence, thereby the thickness of the housing may be reduced, the water purifying, for example, on a wall in a room.

Of course, the waterway plate assembly 100 of the embodiment of the present invention is not limited thereto, and the expanded waterway plate 30 may be disposed at one side of the main waterway plate 10 in the width direction, i.e., in the front-rear direction, so that the overall length of the waterway plate assembly 100 may be reduced, and the overall width of the waterway plate assembly 100 may be increased.

Also, the number of the extended water passage plates 30 may be at least one, that is, the extended water passage plates 30 are not limited to one, for example, one extended water passage plate 30 may be further provided on a side of the extended water passage plate 30 away from the main water passage plate 10, so that the water passage plate assemblies 100 may be sequentially distributed in the length direction, and the two extended water passage plates 30 are in a communication state.

As shown in fig. 11, the extended waterway plate 30 is formed with an extended waterway and a third filter element interface group 32, the extended waterway is respectively communicated with the third filter element interface group 32 and the main waterway, that is, the extended waterway in the extended waterway plate 30 can be communicated with the main waterway, the communication mode can be direct communication or indirect communication, the direct communication means that water passing through the main waterway directly enters the extended waterway, the indirect communication means that water passing through the main waterway passes through other components and then passes through the extended waterway, the other components can be the pump body 200, and the pump body 200 can be a booster pump.

It can be understood that, expanding the water route board 30 can play the role of expanding the water route, so can be on the basis that main water route board 10 structure is fixed, carry out the extension of filtering capability through increasing the mode of expanding water route board 30 to can make water route board subassembly 100 have the effect of increasing the required function filter core, can promote the filtering quality of filter core, can further satisfy user's demand, can promote quality of water and taste moreover.

In addition, the extended waterway plate 30 thus configured may further facilitate the standardized and modular production of the main waterway plate 10 and the extended waterway plate 30, so as to reduce the development of waterway plates and production molds, reduce the production cost of the waterway plate assembly 100, and reduce the cost of the water purifying apparatus S.

In addition, the diversion waterway plate 20 can be disposed on the main waterway plate 10, and can also be disposed on the extended waterway plate 30, so that the diversion waterway plate can be communicated with the third filter element interface set 32, for example, when the extended waterway plate 30 can be matched with a desired filter element, the diversion waterway plate 20 can be added on the extended waterway plate 30, so that the desired filter element can be effectively matched with the extended waterway plate 30, and the requirements of users can be met.

Therefore, according to the waterway plate assembly 100 of the embodiment of the present invention, the main waterway plate 10, the switching waterway plate 20 and the expanded waterway plate 30 are arranged, so that the waterway plate can be conveniently standardized and modularly produced, the research and development of the waterway plate and a production mold can be reduced, the production cost of the waterway plate assembly 100 can be reduced, and the cost of the water purifying equipment S can be reduced, and the waterway plate assembly 100 arranged in this way can effectively meet different requirements of users, and filter elements with different functions can be matched through different splicing combination modes, so that the requirements of users can be met, and the quality and taste of purified water can be improved.

The arrangement of a lower water diversion plate 20 is described in detail below with reference to the accompanying drawings.

According to an alternative embodiment of the present disclosure, as shown in fig. 13 and 14, the projected position of the first cartridge interface set 12 in the horizontal plane is different from the projected position of the corresponding second cartridge interface set 22 in the horizontal plane. That is, the first filter cartridge interface group 12 and the second filter cartridge interface group 22 may be arranged at different positions, so that when the number of interfaces of the first filter cartridge interface group 12 is the same as the number of interfaces of the required filter cartridge, the second filter cartridge interface group 22 at different positions and the interface group of the filter cartridge are matched with the interface group of the required filter cartridge according to the user requirement, thereby completing the installation of the filter cartridge. The number of ports of the first cartridge port set 12 and the number of ports of the second cartridge port set 22 may be two or three.

Specifically, the first filter element interface group 12 has three first interfaces 16, the three first interfaces 16 are a water inlet interface and two water outlet interfaces, and the two water outlet interfaces are a water outlet interface for compressed water and a water outlet interface for purified water, respectively. The second filter element interface group 22 has three second interfaces 25, the three second interfaces 25 are a 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 purified water. Thus, the three first ports 16 and the three second ports 25 can communicate with each other in a one-to-one correspondence via the three transfer passages 21 of the transfer waterway.

As shown in fig. 2 and 11, the centers of the three first ports 16 are sequentially connected to form a first triangle, and the centers of the three second ports 25 are sequentially connected to form a second triangle. When the first filter cartridge interface group 12 can be installed with a filter cartridge with a small diameter, but a filter cartridge with a large diameter is installed at the first filter cartridge interface group 12 according to the requirement of a user, 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 a filter element with a large caliber can be installed on the first filter element interface group 12, but a filter element with a small caliber is installed at the first filter element interface group 12 according to the requirement of a user, 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. Therefore, the modular design of the waterway plate assembly 100 can be realized, and different filter elements can be replaced according to different use requirements of users, so that the users have multiple choices, the use function of the waterway plate assembly 100 is improved, and the requirements of the users can be better met.

It should be noted that, when the diversion waterway plate 20 is already installed on the main waterway plate 10, if the diversion waterway plate 20 has a problem that it cannot be installed, the first filter cartridge interface group 12 of the main waterway plate 10 and the interface group of the required filter cartridge can be in butt communication by detaching the diversion waterway plate 20.

The shapes of the first triangle and the second triangle are the same, namely, each included angle of the first triangle is the same as each included angle of the second triangle, the first triangle and the second triangle can be equilateral triangles, namely, two adjacent included angles between three interfaces of the first filter element interface group 12 are 120 degrees, two adjacent included angles between three interfaces of the second filter element interface group 22 are 120 degrees, the first filter element interface group 12 and the second filter element interface group 22 which are arranged in the way can avoid mutual interference between the adjacent interfaces, and the structural reliability of the main waterway plate 10 and the switching waterway plate 20 can also be ensured.

When the number of the first filter element connector group 12 is two, the two connectors are a water inlet connector and a water outlet connector respectively, and an included angle between one side of the water inlet connector and the other side of the water outlet connector is 120 degrees and an included angle between the other side of the water inlet connector and the other side of the water outlet connector is 240 degrees.

Therefore, by arranging the reasonable three first connectors 16 and the reasonable three second connectors 25, the positions of the connector groups of the waterway plate assembly 100 can be reasonably changed, so that the waterway plate assembly can be matched with a required filter element, and the connection requirement of the current required filter element can be met.

Optionally, as shown in fig. 14, the transfer waterway includes: a plurality of transit passages 21, the transit passages 21 comprising: first vertical section 211, transfer section 212 and second vertical section 213, transfer section 212 connects between first vertical section 211 and second vertical section 213 and has the contained angle with first vertical section 211, and the lower extreme of first vertical section 211 is connected with the interface of first filter core interface group 12, and the upper end of second vertical section 213 is connected with the interface of second filter core interface group 22. Through setting up the transfer section 212, can change the position of second vertical section 213 relative first vertical section 211 to can be connected between the interface of first filter core interface group 12 and the interface of second filter core interface group 22, and can change the interface position of the interface of second filter core interface group 22 relative first filter core interface group 12, thereby can effectively connect required filter core, can satisfy user's demand.

The intermediate section 212 is a horizontal section, and the intermediate section 212 extends in a radial direction of the second cartridge interface group 22. That is, the intermediate section 212 is vertically disposed with respect to the first vertical section 211 and the second vertical section 213, but a connection portion with the first vertical section 211 and a connection portion with the second vertical section 213 may be disposed in a circular arc structure, which may facilitate the flow of water. Moreover, by providing the intermediate section 212 as a horizontal section, the second cartridge interface group 22 can be enlarged or reduced radially and synchronously with respect to the first cartridge interface group 12, so that the interface group of a desired cartridge can be matched. For example, the transitional waterway plate 20 can be configured to be in abutting communication with a small diameter filter cartridge when the transitional segment 212 extends radially inward from the first vertical segment 211, and the transitional waterway plate 20 can be configured to be in abutting communication with a large diameter filter cartridge when the transitional segment 212 extends radially outward from the first vertical segment 211. The thus-arranged transfer section 212 may facilitate formation of the transfer passage 21, and may facilitate effective transfer of the transfer passage 21, and may ensure normal flow of water.

According to another embodiment of the present invention, the number of the interfaces of the first filter element interface group 12 is different from the number of the interfaces of the second filter element interface group 22, and it can be understood that, when the number of the interfaces of the first filter element interface group 12 is different from the number of the interfaces of the required filter element, the interface group of the required filter element can be in butt joint communication by arranging the water diversion circuit board 20 on the main circuit board 10, so that the required filter element can be effectively in butt joint communication, the water purification effect of the water purification apparatus S can be improved, and the quality and taste of purified water can be improved.

Optionally, the number of ports of the first cartridge port set 12 is greater than the number of ports of the second cartridge port set 22, and at least one port of the first cartridge port set 12 is provided with a plug. For example, the number of the first ports 16 of the first cartridge port set 12 on the main waterway plate 10 is three, and when only two cartridges are needed, the adapter waterway plate 20 may have two second ports 25, one of the three adapter channels 21 is closed and one first port 16 is plugged by a plug, and the other two adapter channels 21 are connected between the first ports 16 and the second ports 25.

The first filter element interface group 12 and the second filter element interface group 22 which are arranged in this way can be effectively connected with the required filter elements in a butt joint mode, the problem of water leakage in a water channel can be avoided, the structural reliability of the water channel plate assembly 100 can be further guaranteed, and the reliability of the water purifying equipment S can be guaranteed.

Alternatively, the number of the ports of the first filter cartridge port group 12 is less than that of the ports of the second filter cartridge port group 22, and the switching channel 21 of the switching waterway is provided with at least two branch waterways connected to the ports of the same first filter cartridge port group 12. That is, two water diversion paths can share one interface, so that the interfaces of the required filter element can be matched.

For example, the number of the first ports 16 of the first cartridge port set 12 is two, and when there are three ports of the desired cartridge, the adapter waterway plate 20 may have three second ports 25, and one adapter passage 21 may form two sub-passages to connect the two second ports 25, so that the desired cartridge can be connected in an effective way.

From this, can be when the installation changes water route board 20, the switching passageway 21 in switching water route can become more or less to can adapt to different filter cores, can effectively dock the required filter core of intercommunication, can satisfy user's demand.

According to another embodiment of the present invention, the main channel plate 10 is provided with a first filter cartridge installation groove 15 at a position corresponding to the first filter cartridge interface group 12, the adapting channel plate 20 is provided with a second filter cartridge installation groove 27 at a position corresponding to the second filter cartridge interface group 22, and the first filter cartridge installation groove 15 and the second filter cartridge installation groove 27 have different sizes or the first filter cartridge installation groove 15 and the second filter cartridge installation groove 27 have different shapes so as to adapt to a desired filter cartridge. It can be understood that the filter element includes a filter cartridge and a filter head, the filter head is installed at the end of the filter cartridge, there is a difference in size or shape of the filter head of some filter elements, which will result in that the first filter element installation groove 15 cannot directly install the filter element, and the adapting waterway plate 20 can perform the adapting function, so that it can be effectively adapted to the main waterway plate 10, and the water requirement of the user can be satisfied.
