According to an alternative embodiment of the present disclosure, as shown in fig. 13 and 14, the projected position of the first filter cartridge interface group 12 on the horizontal plane is different from the projected position of the corresponding second filter cartridge interface group 22 on 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.

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.

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 the utility model discloses a further embodiment, the interface quantity of first filter core interface group 12 is different with the interface quantity of second filter core interface group 22, it can be understood that, when the interface quantity of first filter core interface group 12 is different with the interface quantity of the interface group of required filter core, it can dock the interface group of the required filter core of intercommunication through the mode that sets up at main water route board 10 and change water route board 20, so can effectively dock the required filter core of intercommunication, can promote the water purification effect of water purification unit S, can promote the quality and the taste of pure water.

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.

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.

According to the utility model discloses a still another embodiment, main water route board 10 is provided with first filter core mounting groove 15 in the position that corresponds first filter core interface group 12, and switching water route board 20 is provided with second filter core mounting groove 27 in the position that corresponds second filter core interface group 22, and first filter core mounting groove 15 is different with the size of second filter core mounting groove 27, or the shape of first filter core mounting groove 15 and second filter core mounting groove 27 is different to the required filter core of switching. 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.

In some examples of the present invention, as shown in fig. 16, the water purifying apparatus S further includes: skeleton 45 and support frame 46, the diameter of first filter core mounting groove 15 is greater than the diameter of second filter core mounting groove 27, and skeleton 45 sets up in one side of main water route board 10, and support frame 46 supports in the inside of skeleton 45 and inject the filter core installation space, and the filter core holding is in the filter core installation space. The support frame 46 arranged in this way can play a supporting role, so that when the small-diameter filter element is installed on the switching waterway plate 20, the filter element can be supported outside the small-diameter filter element, the problem of installation dislocation of the small-diameter filter element can be avoided, and the installation reliability of the small-diameter filter element can be ensured.
