Of course, the seal 700 can also be integrally injection molded with the second waterway plate body 120. Alternatively, in some embodiments, the seal 700 can also be detachably arranged on the first plug-in portion 112.

[0111] It should be noted that if Figure 6 and Figure 7 As shown, in some embodiments of the utility model, the sealing member 700 is an annular sealing ring, which is located on the outer peripheral wall of the first plug-in portion 112, i.e., the plug-in protrusion. The number of the sealing member 700, i.e., the annular sealing ring, is two. The two annular sealing rings are stacked along the length direction of the first plug-in portion 112 to further improve the sealing of the first waterway plate body 110 and the second waterway plate body 120 when the first plug-in portion 112 and the second plug-in portion 122 are plugged in and matched. The use of two annular sealing rings and stacking them can improve the sealing performance; at the connection, the effects of the two annular sealing rings can be superimposed on each other to form a more stable sealing effect, thereby more effectively preventing liquid leakage; the stacked annular sealing ring structure can enhance the seismic resistance of the connection; after the two sealing rings are stacked, the influence of external vibration and impact on the connection can be better alleviated, and the stability of the connection can be ensured; the reliability of the connection can be improved. If one sealing ring is worn or aged, the other sealing ring can still play a sealing role to ensure the safe operation of the connection. Of course, the number of the sealing members 700 is not limited here, and the sealing members 700 are not limited to the two mentioned above, and the sealing members 700 may also be one, three, etc. Of course, the sealing members 700 mentioned above may also be rubber gaskets, etc.

[0112] Specifically, Figure 6 and Figure 7 As shown, in some embodiments of the present invention, the connection between the first waterway module 210 and the second waterway module 220 passes through the first plug-in portion 112 and the second plug-in portion 122, so as to realize the circulation of liquid and simplify the structure of the waterway plate component, so that when the first plug-in portion 112 and the second plug-in portion 122 are plugged in, the first waterway module 210 of the first waterway plate body 110 and the second waterway module 220 of the second waterway plate body 120 are connected, so as to improve the sealing performance of the waterway plate component, and the structure is compact and the assembly and processing are relatively convenient. Of course, the first plug-in portion 112 and the second plug-in portion 122 can also be arranged at a position far away from the connection between the first waterway module 210 and the second waterway module 220.

[0113] It should be noted that, according to some embodiments of the utility model, the above-mentioned first plug-in portion 112 and the second plug-in portion 122 are both set to four groups. Specifically, it can be understood that the first waterway plate body 110 is provided with a first plug-in portion 112 at the end corresponding to the first waterway 211, the end corresponding to the second waterway 212, the end corresponding to the third waterway 213 and the end corresponding to the fourth waterway 214, and the second waterway plate body 120 is provided with a second plug-in portion 122 at the end corresponding to the fifth waterway 221, the end corresponding to the sixth waterway 222, the end corresponding to the seventh waterway 223 and the end corresponding to the eighth waterway 224.

[0114] Reference Fig. 9 According to an embodiment of the utility model, the first water circuit board body 110 is provided with a tap water inlet 410, a first pure water outlet 420, a first waste water outlet 430 and a first water pump outlet interface 440, and the second water circuit board body 120 is provided with a first water pump inlet interface 450. The working process of the water purifier embodiment is described below:

[0115] The tap water passes through the first mechanical water leakage protection valve and the first water inlet valve 842 and enters the first filter element 810 for coarse filtration. The treated water passes through the booster pump 830 and enters the second filter element 820 for further filtration. The pure water produced after being treated by the second filter element 820 flows through the first one-way valve 843 and the first water pressure switch 844 into the pure water end of the single water outlet device 910 (single water faucet) matched with the water purifier for use by the user. The waste water treated by the second filter element 820 is discharged to the outside as concentrated water through the waste water plug 920.

[0116] Among them, when the pressure of the first one-way valve 843 rises to a predetermined value (for example, 0.26MPa), the first water pressure switch 844 is disconnected; since the booster pump 830 and the first water inlet valve 842 are both connected in series with the first water pressure switch 844, when the first water pressure switch 844 is disconnected, the booster pump 830 stops working, the first water inlet valve 842 closes the entry of tap water, and water production stops; the booster pump 830 stops working, the first water inlet valve 842 closes the entry of tap water, and water production stops; when the pressure of the first one-way valve 843 drops to a predetermined value (for example, 0.09MPa), the first water pressure switch 844 is closed, the first water inlet valve 842 is opened, the booster pump 830 starts working, and water production starts.

[0117] Reference Fig.18 According to an embodiment of the utility model, when the first water channel plate body 110 is provided with a domestic water outlet 510, a second pure water outlet 520, a second waste water outlet 530, a second water pump inlet interface 540 and a second water pump outlet interface 550, the first water channel 211, the working process of the water purifier embodiment is described below:

[0118] The tap water passes through the second mechanical water leakage protection valve 851 and enters the first filter element 810 for coarse filtration. A portion of the treated water flows into the living water end of the double water outlet device 930 (double water faucet) matched with the water purifier as living water for users to use. The other portion of the treated water passes through the second water inlet valve 852 and the booster pump 830 and enters the second filter element 820 for further filtration. The pure water generated after being treated by the second filter element 820 flows into the pure water end of the double water outlet device 930 (double water faucet) matched with the water purifier through the second one-way valve 853 and the second water pressure switch 854 for users to use. The waste water treated by the second filter element 820 is discharged to the outside as concentrated water through the waste water plug 920.

[0119] Among them, when the pressure of the second one-way valve 853 rises to a predetermined value (for example, 0.26MPa), the second water pressure switch 854 is disconnected, and the control board of the water purifier receives the disconnection signal of the second water pressure switch 854, and controls the booster pump 830 to stop working through the program, closes the second water inlet valve 852, and stops water production; when the pressure of the second one-way valve 853 drops to a predetermined value (for example, 0.09MPa), the second water pressure switch 854 is closed, and the control board receives the closing signal of the second water pressure switch 854, controls the second water inlet valve 852 to open through the program, and the booster pump 830 starts working to start water production.
