[0096] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0097] Reference Figures 1-3As shown, the multifunctional water treatment valve of this embodiment includes a valve body 1 and a valve disc assembly disposed within the valve body 1. The valve body 1 is provided with an inlet 2, an outlet 3, a drain outlet 4, an ejector 5, an upper interface 6, and a lower interface 7. The upper interface 6 and the lower interface 7 are connected to a resin tank. The valve disc assembly includes a fixed valve plate 8 and a movable valve plate 9. The fixed valve plate 8 is provided with a first through hole 81, a second through hole 82, a fourth through hole 84, a fifth through hole 85, a sixth through hole 86, a seventh through hole 87, and an eighth through hole 88. The first through hole 81 and the second through hole 82... All are connected to the upper interface 6; the fourth through hole 84 is connected to the outlet 3; the fifth through hole 85 is connected to the lower interface 7; the sixth through hole 86 is connected to the outlet of the ejector 5; the seventh through hole 87 is connected to the inlet of the ejector 5; and the eighth through hole 88 is connected to the drain outlet 4. The fourth through hole 84 and the fifth through hole 85 occupy the same and maximum area. The moving valve plate 9 is provided with a first water inlet channel 91, a connecting channel 94, and a drain channel 95. The first water inlet channel 91 is connected to the inlet 2 for water intake, and the drain channel 95 is connected to the eighth through hole 88. By setting the fourth through hole 84 and the fifth through hole 85 to be the same and maximum area, the flow area of ​​water from the resin tank to the lower interface and then to the outlet is maximized, reducing the number of equal flow channels and increasing the flow area. This solves the problem of multiple equal flow channel divisions and small flow area in the background technology, and improves water treatment efficiency.

[0098] Furthermore, the area occupied by the sixth through hole 86 and / or the first through hole 81 is smaller than that occupied by the fourth through hole 84 and the fifth through hole 85. By adjusting the proportion of the through holes, the water flow distribution is made more reasonable, maximizing the flow area from the resin tank to the lower interface and then to the outlet, while reducing the flow area through the ejector. This improves the flow adaptability under different functional modes and enhances the working efficiency of the valve assembly.

[0099] Furthermore, the outermost edge of the fixed valve plate 8 has a protrusion, and the seventh through hole 87 is located within the protrusion, without occupying the equal space. This design, by placing the seventh through hole 87 within the protrusion, avoids occupying the main equal space, further optimizes the space utilization of the fixed valve plate 8, and provides more space for the layout of other through holes.
