[0004] The waterway panel of an under-sink water purifier is typically equipped with front and rear filter cartridges, a reverse osmosis filter, a water inlet solenoid valve, a high-pressure switch, a check valve, a return solenoid valve, and more. Due to the complex waterway structure of a water purifier, the system is typically split into two halves, each injection-molded separately. These halves are then welded together using specialized hot-melt welding equipment to create a complete waterway panel.

[0005] During the welding process of the waterway plate, professional equipment is required for welding and forming, the process is complicated, the production cost is high, and the welding consistency is difficult to guarantee. This can easily cause problems such as water leakage in the waterway of the waterway plate or welding slag blocking the waterway.

[0006] In the prior art, due to the complexity of the water channel of the water purifier, it is usually necessary to divide the water channel into two or more parts, which are injection-molded separately and then sealed and connected to form a complete water channel plate.

[0007] Sealing rings are often required at the connection points between the two parts of the waterway plate. When multiple connection points are assembled, multiple sealing rings need to be manually installed, which is time-consuming and labor-intensive, and has low assembly efficiency.

[0008] In the prior art, due to the water channel arrangement of the water channel plate in the water purifier, there is resistance when the liquid flows in the water channel plate, and the liquid flow is relatively unsmooth, affecting the water purification time of the water purifier and further affecting the water purification efficiency.

[0009] In the prior art, the water channel arrangement of the water purifier makes the injection molding process of the water channel plate complicated, making it inconvenient to remove the film and easy to get stuck on the mold. The demolding efficiency of the water channel plate is low, which leads to low production efficiency and high cost of the water purifier.

The working process of this water purifier embodiment is described below:

[0302] Tap water passes through the first mechanical water leakage protection valve and the first water inlet valve 842C and enters the first filter element 810C for coarse filtration. The treated water then passes through the booster pump 830C and enters the second filter element 820C for further filtration. After being treated by the second filter element 820C, the pure water produced flows through the first one-way valve 843C and the first water pressure switch 844C into the pure water end of the single water outlet device 910C (single water faucet) that is compatible with the water purifier for consumption by the user. Wastewater treated by the second filter element 820C passes through the wastewater plug 920C and is discharged as concentrated water to the outside.

[0303] Among them, when the pressure of the first one-way valve 843C rises to a predetermined value (for example, 0.26MPa), the first water pressure switch 844C is disconnected; since the booster pump 830C and the first water inlet valve 842C are both connected in series with the first water pressure switch 844C, when the first water pressure switch 844C is disconnected, the booster pump 830C stops working, the first water inlet valve 842C closes the entry of tap water, and water production stops; the booster pump 830C stops working, the first water inlet valve 842C closes the entry of tap water, and water production stops; when the pressure of the first one-way valve 843C drops to a predetermined value (for example, 0.09MPa), the first water pressure switch 844C closes, the first water inlet valve 842C opens, the booster pump 830C starts working, and water production starts.

[0304] 28 , in some embodiments, when the first water channel plate 110C is provided with a domestic water outlet 510C, a second pure water outlet 520C, a second waste water outlet 530C, a second water pump inlet interface 540C, and a second water pump outlet interface 550C, the first water channel 211C, the working process of the water purifier embodiment is described below:

[0305] Tap water passes through the second mechanical water leakage protection valve 851C and enters the first filter element 810C for coarse filtration. A portion of the treated water flows as domestic water to the domestic water end of the dual water outlet device 930C (dual water faucet) coordinated with the water purifier for user use. The other portion of the treated water passes through the second water inlet valve 852C and the booster pump 830C and enters the second filter element 820C for further filtration. After being treated by the second filter element 820C, the pure water produced flows through the second one-way valve 853C and the second water pressure switch 854C to the pure water end of the dual water outlet device 930C (dual water faucet) coordinated with the water purifier for user use. The waste water treated by the second filter element 820C is discharged to the outside as concentrated water through the wastewater plug 920C.

[0306] Among them, when the pressure of the second one-way valve 853C rises to a predetermined value (for example, 0.26MPa), the second water pressure switch 854C is disconnected, and the control panel of the water purifier receives the disconnection signal of the second water pressure switch 854C, and controls the booster pump 830C to stop working through the program, closes the second water inlet valve 852C, and stops water production; when the pressure of the second one-way valve 853C drops to a predetermined value (for example, 0.09MPa), the second water pressure switch 854C is closed, the control panel receives the closing signal of the second water pressure switch 854C, controls the second water inlet valve 852C to open through the program, and the booster pump 830C starts working to start water production.

With this structure, the sealing structure 270 can provide a physical barrier, ensuring the sealing of the connection gap between the first waterway plate body 210 and the second waterway plate body 220 through the first plug-in structure 230 and the second plug-in structure 240, preventing liquid leakage and helping to prevent dust, particulate matter, or other impurities from the external street environment from entering the waterway plate assembly 200, thereby protecting the functionality and reliability of the waterway plate assembly 200.

[0333] It is understood that in the embodiment of the present invention, the first waterway plate body 210 and the sealing structure 270 are integrally injection molded. This means that during the injection molding process of the first waterway plate body 210, the first waterway plate body 210, the first plug-in structure 230, and the sealing structure 270 are directly injection molded into the mold. After molding, the first waterway plate body 210 removed from the mold is a structure with the sealing structure 270. This eliminates the need to manually install the sealing structures 270 one by one, greatly improving the assembly efficiency of the waterway plate assembly 200 and saving time and effort. Of course, the sealing structure 270 can also be integrally injection molded with the second waterway plate body 220. Alternatively, in some embodiments, the sealing structure 270 can also be detachably attached to the first plug-in structure 230.

[0334] It should be noted that, with reference to FIG44 , in this embodiment, the sealing structure 270 is an annular sealing ring located on the outer peripheral wall of the first plug-in structure 230 , i.e., the plug-in protrusion. The number of the sealing structures 270 , i.e., the annular sealing rings, is two, and the two annular sealing rings are stacked along the length direction of the first plug-in structure 230 to further improve the sealing performance of the first waterway plate body 210 and the second waterway plate body 220 when the first plug-in structure 230 and the second plug-in structure 240 are plugged in. The use of two annular sealing rings and their stacking can improve the sealing performance. At the connection, the effects of the two sealing rings can be superimposed on each other to form a more stable sealing effect, thereby more effectively preventing liquid leakage. The stacked sealing ring structure can enhance the seismic resistance of the connection. After the two sealing rings are stacked, they can better mitigate the effects of external vibration and impact on the connection, ensuring the stability of the connection, and thus improving the reliability of the connection. If one sealing ring is worn or aged, the other sealing ring can still function as a seal, ensuring the safe operation of the connection. Of course, the number of the sealing structures 270 is not limited here, and the sealing structures 270 are not limited to the two mentioned above, and the sealing structures 270 can also be one, three, etc. Of course, the sealing structure 270 can also be a rubber gasket, etc.
