Then, it flows through the second regeneration channel 10032 into the third opening 1103 and into the second fluid inlet 521 of the second water treatment device 52, regenerating the fluid in the second water treatment device 52 in a downstream manner. Water treatment materials or components, such as softening resin, flow out from the second fluid outlet 522 of the second water treatment device 52, then flow through the fourth opening 1104 of the valve body 11 into the third regeneration channel 10033, and then discharge from the drain opening 1112; when the water treatment system is in the second regeneration working state, the first raw water flows in from the first inlet opening 1105 of the valve body 11, then flows through the fourth regeneration channel 10034 into the first jet opening 1131, and then into the jet outlet 321 of the ejector 31, and is jetted through the ejector 31, mixing with the brine inlet 32. The brine from the brine tank 32 of the 3rd generation flows into the second jet opening 1132 of the valve body 11 through the injection inlet 322 of the ejector 31, then flows into the second opening 1102 through the fifth regeneration channel 10035, enters the first fluid outlet 512 of the first water treatment device 51, and regenerates the water treatment materials or mechanisms in the first water treatment device 51, such as softening resin, through countercurrent regeneration. Then it flows out from the first fluid inlet 511 of the first water treatment device 51, then flows through the first opening 1101 of the valve body 11 into the sixth regeneration channel 10036, and then is discharged from the drain opening 1112.When the water treatment system is in the water replenishment working state, the first raw water flows sequentially through the first water inlet 1105, the first water replenishment channel 10041 and the first opening 1101 of the valve body 11, and flows into the first water treatment device 51 through the first fluid inlet 511.

After being jetted by the jet ejector 31, the first raw water mixes with the brine from the brine inlet 323 and then flows into the second jet opening 1131B of the valve body 11B through the jet inlet 322 of the jet ejector 31. 132B, then flows through the fifth regeneration channel 10035B to the first opening 1101B and from the first fluid inlet 511 to the first water treatment device 51, regenerating the water treatment materials or components in the first water treatment device 51, such as water softening resin, and then flows out from the first fluid outlet 512 of the first water treatment device 51. It then flows through the second opening 1102B of the valve body 11B into the sixth regeneration channel 10036B, and then flows out from the drain opening 1112B.

When the planar valve 10B of the water treatment system is in the water replenishment working position, the fifth channel 105B of the planar valve 10B is connected to the second jet channel 1032B, thereby forming the first water replenishment channel 10041B, which is connected to the first water inlet 1105B and the second jet opening 1132B of the valve body 11B respectively. This allows the first raw water to flow sequentially through the first water inlet 1105B, the first water replenishment channel 10041B, the second jet opening 1132B, the jet inlet 322 and the brine suction port 323 of the jet injector 31 into the brine tank 32 and replenish the brine tank 32.

[0287] As shown in the attached image. Figures 34A to 41F As shown, further, when the plane valve 10B of the water treatment system is in the water treatment working position, the first jet channel 1031B and the second jet channel 1032B are respectively blocked by the second fluid control surface 1220B of the moving valve plate 122B (or, in other words, one end of the first fluid control surface 1210B of the first jet channel 1031B and the second jet channel 1032B located on the fixed valve plate 121B is respectively closed by the moving valve plate 122B); when the plane valve 10B of the water treatment system is in the first backwash working position, the first jet channel 1031B and the second jet channel 1032B are respectively blocked by the second fluid control surface 1220B of the moving valve plate 122B.

[0288] As shown in the attached image. Figures 34B to 34F , Figures 36A to 40B and Figures 41B to 41FAs shown, when the planar valve 10B is in the first backwash working position, the second backwash working position, the first regeneration working position, the second regeneration working position, and the water replenishment working position, the sixth channel 106B of the planar valve 10B is connected to the first water inlet opening 1105B through the valve cavity 110B of the valve body 11B, thereby forming the first raw water supply channel 10001B, which is connected to the first water inlet opening 1105B and the first water outlet opening 1106B of the valve body 11B respectively. This allows the first raw water to flow in from the first water inlet opening 1105B and from the first raw water supply channel 10001B. The first and second raw water flows from channel 10001B to the first outlet opening 1106B of the valve body 11B for supply; the seventh channel 107B and the eighth channel 108B of the plane valve 10B are connected through the conducting channel 1015B, thereby forming a second raw water supply channel 10002B that is respectively connected to the second inlet opening 1107B and the second outlet opening 1108B of the valve body 11B, so that the second raw water can flow in from the second inlet opening 1107B and from the second raw water supply channel 10002B to the second outlet opening 1108B of the valve body 11B for supply. In other words, when the first and second raw water are at the first backwash position, the second backwash position, the first regeneration position, the second regeneration position, and the water replenishment position of the plane valve 10B, they are directly supplied without being treated by the first water treatment device 51 and the second water treatment device 52. In practical use, the water treatment system requires a certain amount of time (approximately 1 hour) to complete the entire flushing, regeneration, and water replenishment process (first backwash station, second backwash station, first regeneration station, second regeneration station, and water replenishment station). Therefore, throughout the entire flushing, regeneration, and water replenishment process, the water treatment system can continue to supply first and second raw water through the first raw water supply channel 10001B and the second raw water supply channel 10002B to prevent users from experiencing water shortages or interruptions.

The first and second raw water flows from channel 10001B to the first outlet opening 1106B of the valve body 11C for supply; the seventh channel 107B and the eighth channel 108B of the plane valve 10C are connected through the conductive channel 1015B, thereby forming a second raw water supply channel 10002B that is respectively connected to the second inlet opening 1107B and the second outlet opening 1108B of the valve body 11C, so that the second raw water can flow in from the second inlet opening 1107B and from the second raw water supply channel 10002B to the second outlet opening 1108B of the valve body 11C for supply. In other words, the first and second raw water are directly supplied without being treated by the first water treatment device 51 and the second water treatment device 52 when the plane valve 10C is in the first backwash position, the second backwash position, the first regeneration position, the second regeneration position, and the water replenishment position.
