[0029] The waterway plate body 100 of the application can be integrally formed after metal casting, can be formed by machining a stainless steel plate by a machine tool, can be integrally formed, or can be assembled by several modules. Preferably, the stainless steel plate is machined by a machine tool, so that the sand hole caused by poor annealing in the casting process is avoided. Compared with the integrally formed injection molding in the prior art, the stainless steel waterway plate is more stable, is not easy to be deformed by temperature, greatly reduces the risk of water leakage, and has stable processability and good antibacterial property, and is not easy to breed bacteria.

[0030] Please refer to Figures 1-4The waterway plate further has a first bridging pipe 200 located outside the waterway plate body 100, one end of the first bridging pipe 200 being connected to the second water outlet 42, and the other end being in communication with the pure water outlet 3. Specifically, the waterway plate body 100 is provided with a first bridging pipe water inlet hole 201 and a first bridging pipe water outlet hole 202, the first bridging pipe water inlet hole 201 being in communication with the second water outlet 42, and the second-stage filtered pure water being guided into the first bridging pipe 200 through the second water outlet 42, the first bridging pipe water outlet hole 202 being in communication with the pure water outlet 3, and the second-stage filtered pure water being guided out, so that a new connecting flow channel is not added inside the waterway plate body 100, thereby directly crossing the internal flow channel, simplifying the structure of the waterway plate, and facilitating the processing of the waterway plate body. In this embodiment, the flow of water between the first bridging pipe water outlet hole 202 and the pure water outlet 3 can be realized by using a composite filter element structure.

The second bridge pipe 300 realizes the water flow channel between the electromagnetic valve and the booster pump, so that the flow channel for connecting the electromagnetic valve and the booster pump does not need to be arranged inside the waterway plate body 100, and the structure of the waterway plate body 100 is more compact. Specifically, the waterway plate body 100 is provided with a second bridge pipe water inlet hole 301 and a second bridge pipe water outlet hole 302.

When the electromagnetic valve is in an open state, the clean water flow is guided from the first water outlet 41 into the waterway plate body 100, and then guided into the second bridge pipe 300 through the second bridge pipe water inlet hole 301, and then guided into the booster pump through the second bridge pipe water inlet hole 301, and finally guided into the secondary filter element from the water outlet 43 of the booster pump.

[0034] In the embodiment, the first bridge pipe 200 and the second bridge pipe 300 are both pipes made of stainless steel, so that the pipes through which the water flows are all made of stainless steel, and bacteria are less likely to breed.

[0035] Please refer to Figure 2 and Figure 5 The waterway plate body 100 further comprises a second waste water outlet 62, a third waste water outlet 63, a waste water valve water outlet 45 and a waste water valve water inlet 55.

The first waste water outlet 61 is in communication with the waste water valve water outlet 45, the waste water valve water inlet 55 is in communication with the third waste water outlet 63, and the second waste water outlet 62 is in communication through a third bridge pipe (not shown in the figure), so as to guide the waste water generated by the secondary filter element into the third bridge pipe and then discharge the waste water through the second waste water outlet 62. The waste water valve can prevent the waste water from flowing back, the third bridge pipe can realize waste water discharge, and the flow channel inside the waterway plate body 100 can be avoided, and the waste water flow channel can also be avoided from crossing with other flow channels.

[0036] In the embodiment, the raw water inlet 1, the clean water outlet 2, the pure water outlet 3 and the second waste water outlet 62 are located on the same side of the waterway plate body 100, specifically, on the short side of the waterway plate body 100, which is convenient for installation and maintenance of external pipelines. In addition, the electromagnetic valve outlet 54, the electromagnetic valve inlet 44 and the booster pump inlet 53 are located on the same side of the waterway plate body 100, specifically, on the long side of the waterway plate body 100, which makes full use of the space outside the waterway plate body 100 to install the booster pump and the electromagnetic valve, so that the whole waterway plate structure is compact and convenient for maintenance without disassembling and separating the whole waterway plate and the filter assembly.
