Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and more particularly to a water treatment machine capable of purifying and softening water. Furthermore, the water treatment machine of this invention includes both a purification device (purification filter element) and a softening device (softening tank), both configured to purify and soften raw water (or water to be treated) via a single control valve, thereby allowing the user to simultaneously obtain purified and softened water. Background Technology

[0002] With increasing emphasis on health and concerns about water pollution, water treatment machines or systems have become common household appliances. Water treatment machines, especially household ones such as central water purifiers and water softeners, are often installed in kitchens to treat water and obtain cleaner water.

[0003] Depending on the treatment method used for raw water or water to be treated, water treatment machines can generally be divided into water purifiers and water softeners. Common water purifiers, such as activated carbon filter water purifiers, ultrafiltration water purifiers, and RO membrane water purifiers, are mainly designed to remove impurities from the water as much as possible, such as harmful substances and odors. Water softeners, on the other hand, primarily remove ions such as calcium ions from the water. Water purifiers like ultrafiltration and RO membrane water purifiers produce relatively cleaner and more drinkable water, while water softeners produce soft water that contains fewer calcium ions, making it more suitable for bathing and washing clothes. Some people also believe that soft water is better for beauty treatments. However, most existing water treatment machines with multi-functional water treatment are simply water purification systems, such as activated carbon-ultrafiltration composite water purification systems, ultrafiltration-RO membrane composite water purification systems, and PP cotton-activated carbon composite water purification systems. Composite water purification and softening systems are extremely rare. The main reason is that water purification and water softening differ significantly in their mechanisms. When purifying incoming water, users need to replace the filter cartridges regularly to prevent them from losing their purification function after prolonged use. For example, although rinsing can extend the lifespan of the filter cartridges, activated carbon and ultrafiltration cartridges still require replacement after extended use. After using a water softener for a period of time, the softener needs to be regularly replenished with brine (usually NaCl solution) and cleaned to prevent the softening resin from losing its activity and to remove impurities. In addition to replenishing the brine in the softening tank, the water softener also needs to replenish water in its brine (solution) tank to prevent the brine in the brine tank from running out and to ensure a continuous supply of brine to the softening tank. However, all water treatment machines involve water flow control. Due to the complexity of the structure and function of water softeners, combined purification and softening water treatment systems require intricate water circuits and proper control. To simultaneously control both the purified and softened water circuits, most existing combined purification and softening water treatment systems have more than two control valves, resulting in a bulky, cumbersome structure and a poor user experience. Furthermore, water treatment systems, especially household ones, are typically installed under kitchen countertops, such as under the sink. The large size of existing combined purification and softening water treatment systems occupies excessive space, causing significant inconvenience for users during installation. Not to mention the difficulties in maintenance and filter replacement when the system malfunctions. Moreover, existing combined purification and softening water treatment systems rarely provide purified water simultaneously during the softening process. Some even only provide softened water, forcing users to obtain purified water through additional purification systems.Finally, for safety reasons, water treatment equipment, especially water treatment machines with combined water treatment functions, needs to continuously supply water (or raw water) even when not in water treatment operation. However, most existing purification-softening combined water treatment machines can only supply purified water and / or softened water in the purification and / or softening function positions, and cannot continuously supply water in other operating states, such as the cleaning state of the purification filter cartridge of the purification device.

Figures 1 to 30G As shown, the control valve 10 of the water treatment machine according to a preferred embodiment of the present invention is a planar valve, wherein the planar valve 10 further includes a movable valve plate 13 and a fixed valve plate 12, wherein the fixed valve plate 12 has a first fluid control surface 120, and the movable valve plate 13 has a second fluid control surface 130, wherein the movable valve plate 13 and the fixed valve plate 12 are both disposed in the inner cavity 110, wherein the second fluid control surface 130 of the movable valve plate 13 is disposed on the first fluid control surface 120 of the fixed valve plate 12, and the movable valve plate 13 is configured to rotate relative to the fixed valve plate 12, wherein the purification device 20 has a first communicating opening 201 and a second communicating opening 202. The softening device 30 includes a softening box 31 with two connecting openings 202. The softening box 31 has a first connecting opening 301 and a second connecting opening 302. The inner cavity 110 of the valve body 11 communicates with the first opening 1101. The first connecting opening 201 of the purification device 20 communicates with the fifth opening 1105 of the valve body 11. The second connecting opening 202 of the purification device 20 and the first connecting opening 301 of the softening box 31 are both connected to the sixth opening 1106 of the valve body 11. The second connecting opening 302 of the softening box 31 communicates with the seventh opening 1107 of the valve body 11. Therefore, when the fluid valve 10 is a planar valve, the valve core 1 of the fluid valve 10 includes a moving valve plate 13 and a fixed valve plate 12. Furthermore, it can be understood that, since the inner cavity 110 of the valve body 11 of the planar valve 10 is connected to the first opening 1101, the water to be treated is supplied through the first opening 1101 and the inner cavity 110.

[0152] As shown in the attached image. Figures 1 to 30GAs shown, the softening device 30 of the water treatment machine according to a preferred embodiment of the present invention further includes an ejector 32 and a brine tank 33, wherein the ejector 32 has an ejector outlet 321 adapted to communicate with the third opening 1103 of the valve body 11 and an ejector inlet 322 adapted to communicate with the fourth opening 1104 of the valve body 11, wherein the brine tank 33 is adapted to communicate with the ejector 32, so that the brine from the brine tank 33 can flow through the ejector 32 and the fourth opening 1104, and through the planar valve 10 to the softening tank 31 of the softening device 30, thereby regenerating the softening resin in the softening tank 31. Accordingly, when the water treatment machine of the present invention is in a brine regeneration working state of a softening filter (or softening tank), the raw water or water to be treated flows from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, then flows into the third opening 1103 through an eighth connecting channel 1008, and then flows into the ejection outlet 321 of the ejector 32. After being ejected by the ejector 32, the liquid from the brine tank 33 is mixed and then flows into the brine tank 33 through the injection inlet 322 of the ejector 32. The brine flows through the fourth opening 1104 of the valve body 11, then through a ninth connecting channel 1009 into the seventh opening 1107, and into the second conducting opening 302 of the softening tank 31. After regenerating the water treatment material or mechanism, such as softening resin, in the softening tank 31, it flows out from the first conducting opening 301, then through the sixth opening 1106 of the valve body 11 into a tenth connecting channel 10010, and then out from a ninth opening 1109 of the plane valve 10. It is understood that although the present invention only exemplarily describes the method of providing brine to the softening tank 31 via the ejector 32, the brine can also be provided to the softening tank 31 through the fourth opening 1104 of the plane valve 10 via other methods or mechanisms. Therefore, the method of providing brine to the softening tank 31 via the ejector 32 should not be considered a limitation of the present invention.

[0153] Those skilled in the art will understand that the planar valve 10 of the water treatment machine of the present invention may further have a connection mechanism provided on the valve body 11, such as a connecting thread, a snap-fit ​​connector, etc., so that the planar valve 10 can be connected to other structural components of the water treatment machine, such as a purification device, a softening device, etc., so as to guide the water flow to the softening tank of the purification device, the softening device and the various connecting channels formed by the planar valve 10 respectively.

[0154] As shown in the attached image. Figures 1 to 30GAs shown, the water treatment machine according to a preferred embodiment of the present invention has a first working state, a second working state, and a third working state. When the water treatment machine is in the first working state, the moving valve plate 13 and the fixed valve plate 12 of the planar valve 10 form a first communicating channel 1001 connected to the first opening 1101 and the fifth opening 1105 of the valve body 11, a second communicating channel 1002 connected to the second opening 1102 and the seventh opening 1107 of the valve body 11, and a third communicating channel 1003 connected to the sixth opening 1106 and the eighth opening 1108 of the valve body 11.

When the water treatment machine is in the third working state, the movable valve plate 13 and the fixed valve plate 12 of the plane valve 10 form a sixth communication channel 1006 that is connected to the first opening 1101 and the sixth opening 1106 of the valve body 11, and a seventh communication channel 1007 that is connected to the fifth opening 1105 of the valve body 11 and the ninth opening 1109 of the plane valve 10, respectively.

The purification device 20 purifies the raw water, and the purified water flows out from the second connecting opening 202 of the purification device 20. Then the purified water is divided into two paths. One path of purified water flows into the softening tank 31 through the first conducting opening 301 and is softened to obtain softened water. The softened water flows out from the second conducting opening 302 of the softening tank 31, and then through the seventh opening 1107 of the valve body 11 and the second connecting channel 1002 of the plane valve 10. Finally, it flows out through the second opening 1102 of the valve body 11 and is supplied to the user. The other path of purified water flows through the sixth opening 1106 of the valve body 11 and the third connecting channel 1003 of the plane valve 10. Finally, it flows out through the eighth opening 1108 of the valve body 11 and is supplied to the user. Therefore, when the water treatment machine is in the first operating state, the water treatment machine of the present invention can simultaneously provide users with purified water and softened water. Accordingly, the first operating state of the water treatment machine corresponds to the purification-softening operating state of the water treatment machine.

Meanwhile, the sixth opening 1106 of the valve body 11, the third connecting channel 1003 of the plane valve 10 and the eighth opening 1108 of the valve body 11 form a clean water supply branch (waterway) to provide clean water to the user.

After backwashing the softening material (or water treatment material), such as softening resin, in the softening tank 31, the resulting sewage or wastewater flows out from the first guiding opening 301 of the softening tank 31, then flows through the sixth opening 1106 of the valve body 11 into the fifth connecting channel 1005 of the plane valve 10, and then flows out from the ninth opening 1109 of the plane valve 10. In other words, when the water treatment machine is in the second working state, the water treatment machine of the present invention can control the backwashing of the softening filter element, such as the softening tank 31. Accordingly, the second working state of the water treatment machine corresponds to the backwashing working state of the softening filter element of the water treatment machine.

The third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106, the seventh channel 107, the eighth channel 108, and the twelfth channel 1012 are respectively formed in the channel openings of the first fluid control surface 120 of the fixed valve plate 12, and the ninth channel 109, the tenth channel 1010, the eleventh channel 1011, and the thirteenth channel 1013 are respectively formed in the channel openings of the second fluid control surface 130 of the movable valve plate 13. They can have any shape that enables the interconnection relationship described herein. For example, the channel opening of the eighth channel 108 in the first fluid control surface 120 of the fixed valve plate 12 can be configured to have a regular shape or an irregular shape. Therefore, the extension paths (or directions) and the shapes of the openings of the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106, the seventh channel 107, the eighth channel 108, the ninth channel 109, the tenth channel 1010, the eleventh channel 1011, the twelfth channel 1012, and the thirteenth channel 1013 of the planar valve 10 should not be considered as limitations on the present invention.

[0180] As shown in the attached image. Figures 17A to 18GAs shown, preferably, the channel being closed in this document means that the channel openings formed on the first fluid control surface 120 of the fixed valve plate 12 and the second fluid control surface 130 of the moving valve plate 13 of the planar valve 10 are covered by the solid parts of the moving valve plate 13 and the fixed valve plate 12 at the specific working position of the planar valve 10 (or the working state of the water treatment machine), thereby preventing the corresponding channels from being connected through the channel openings. For example, when the planar valve 10 is in the first working position, the solid portion of the moving valve plate 13 is directly facing the opening of the sixth channel 106 and the seventh channel 107 of the planar valve 10 in the channel opening of the first fluid control surface 120 of the fixed valve plate 12, thereby closing (or blocking) the sixth channel 106 and the seventh channel 107 of the planar valve 10 by the moving valve plate 13, and the solid portion of the fixed valve plate 12 is directly facing the opening of the eleventh channel 1011 of the planar valve 10 in the channel opening of the second fluid control surface 130 of the moving valve plate 13, thereby closing the eleventh channel 1011 of the planar valve 10 by the fixed valve plate 12. Accordingly, the connection between the channel of the moving valve plate 13 and the channel of the fixed valve plate 12 in this article refers to the selective partial or complete alignment of the channel of the moving valve plate 13 forming the channel opening of the second fluid control surface 130 of the moving valve plate 13 and the channel of the fixed valve plate 12 forming the channel opening of the first fluid control surface 120 of the fixed valve plate 12 in the specific working position of the planar valve 10 (or the working state of the water treatment machine), forming a water flow path that allows water to flow through. For example, when the planar valve 10 is in the first working position, the ninth channel 109 of the planar valve 10 is aligned with the first channel 101, thereby connecting the two and forming the first connecting channel 1001. The tenth channel 1010 is aligned with the third channel 103 and the fifth channel 105, respectively, thereby connecting the two and forming the second connecting channel 1002. The thirteenth channel 1013 is aligned with the eighth channel 108 and the twelfth channel 1012, respectively, thereby connecting the two and forming the third connecting channel 1003.

[0185] Preferably, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the sixth channel 106, the seventh channel 107, and the eighth channel 108 of the planar valve 10 are respectively disposed on the first extension 122 of the first fluid control surface 120 of the fixed valve plate 12; the fifth channel 105 is disposed on the first edge 123 of the first fluid control surface 120 and extends inward from the first edge 123; and the twelfth channel 1012 is disposed on the first edge 123 of the first fluid control surface 120. More preferably, the fifth channel 105 is disposed on the first edge 123 of the first fluid control surface 120 and extends inward from the first edge 123 to the first extension 122 of the first fluid control surface 120.

[0186] Preferably, the ninth channel 109 and the eleventh channel 1011 of the planar valve 10 are respectively disposed on the second extension 132 of the second fluid control surface 130 of the moving valve plate 13, and the tenth channel 1010 and the thirteenth channel 1013 are respectively disposed on the second edge 133 of the second fluid control surface 130 of the moving valve plate 13 and extend inward from the second edge 133 to the second extension 132.

[0187] Preferably, the first channel 101 of the planar valve 10 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12; the second channel 102 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12; the third channel 103 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12; the fourth channel 104 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12; and the fifth channel 105 extends downward and outward from the fixed valve plate 12. The first fluid control surface 120 of the fixed valve plate 12 extends downward and outward; the sixth channel 106 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12; the seventh channel 107 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12; the eighth channel 108 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12; and the twelfth channel 1012 extends downward and outward from the first fluid control surface 120 of the fixed valve plate 12.

[0188] As shown in the attached image. Figures 1 to 7 As shown, in a preferred embodiment of the water treatment machine according to the present invention, the valve body 11 of the planar valve 10 has an inner wall 111, wherein the fixed valve plate 12 is adapted to be disposed in the inner cavity 110 with the first fluid control surface 120 facing upward, and the movable valve plate 13 is adapted to be disposed in the inner cavity 110 with the second fluid control surface 130 facing downward, wherein the inner cavity 110 is always connected to the ninth channel 109. It is worth noting that the fixed valve plate 12 of the planar valve 10 can be detachably disposed in the inner wall 111 of the valve body 11, or it can be integrally formed with the inner wall 111 of the valve body 11 of the planar valve 10. Those skilled in the art will understand that when the fixed valve plate 12 is detachably disposed in the valve body 11, the fixed valve plate 12 and the valve body 11 are kept synchronized by a fixing mechanism. For example, as shown in the figures... Figures 1 to 7As shown, the fixed valve plate 12 has a braking element 123 protruding outward from its edge, and the inner wall 111 of the valve body 11 has a braking groove 1110. The braking element 123 of the fixed valve plate 12 is configured to engage with the braking groove 1110 of the inner wall 111 of the valve body 11 to ensure synchronization (or prevent relative rotation) between the fixed valve plate 12 and the valve body 11, and to ensure that the various channels of the fixed valve plate 12 communicate with the corresponding openings of the valve body 11. It can be understood that when the fixed valve plate 12 is detachably disposed within the valve body 11, it can be manufactured separately. In other words, the fixed valve plate 12 can be made of a wear-resistant material, thereby improving the service life of the fixed valve plate 12 (or the entire planar valve). Preferably, the first fluid control surface 120 of the fixed valve plate 12 is smoothed to reduce its roughness.

[0189] As shown in the attached image. Figures 1 to 7 As shown, the planar valve 10 of the water treatment machine according to a preferred embodiment of the present invention further includes a flow guiding element 15, wherein the flow guiding element 15 forms the sewage discharge channel 150, wherein the flow guiding element 15 is arranged to extend upward from the movable valve plate 13 and the sewage discharge channel 150 of the flow guiding element 15 is respectively connected to the ninth opening 1109 and the eleventh channel 1011 of the planar valve (the ninth opening 1109 is arranged in the valve body 11 of the planar valve 10), or the sewage discharge channel 150 is directly connected to the ninth opening 1109 (the ninth opening 1109 is arranged in the movable valve plate 13 of the planar valve 10 and is connected to the eleventh channel 1011), so that sewage or wastewater can flow out from it.

[0190] As shown in the attached image. Figures 1 to 7 As shown, the planar valve 10 of the water treatment machine according to a preferred embodiment of the present invention further includes a drive element 18 extending upward from the movable valve plate 13, wherein the drive element 18 is configured to drive the movable valve plate 13 of the planar valve 10 to rotate relative to the fixed valve plate 12. Preferably, the drive element 18 and the flow guiding element 15 are integrally formed. Optionally, the drive element 18 and the flow guiding element 15 are two independent mechanisms.

[0191] As shown in the attached image. Figures 1 to 7As shown, the planar valve 10 of the water treatment machine according to a preferred embodiment of the present invention further includes a sealing element 17, wherein the sealing element 17 is disposed facing the drive element 18, wherein the sealing element 17 forms a first sealing surface 170, and the drive element 18 forms a second sealing surface 180, wherein the first sealing surface 170 of the sealing element 17 is disposed on the second sealing surface 180 of the drive element 18, thereby sealing and preventing water leakage between the drive element 18 and the sealing element 17 when the drive element 18 rotates relative to the sealing element 17 to drive the movable valve plate 13 to rotate relative to the fixed valve plate 12. Furthermore, the sealing element 17 is configured to maintain the drive element 18 in an appropriate position, thereby maintaining the movable valve plate 13 in a preset position.

[0192] As shown in the attached image. Figures 1 to 7 As shown, in a preferred embodiment of the water treatment machine, the diameter of the moving valve plate 13 of the planar valve 10 is set to be slightly smaller than the diameter of the inner cavity 110 of the valve body 11, so that the ninth channel 109 of the planar valve 10 can be kept in communication with the inner cavity 110 of the valve body 11 through the inlet 1091.

[0193] As shown in the attached image. Figures 8A to 14 and Figures 16A to 16GAs shown, according to a preferred embodiment of the water treatment machine, the control device 16 of the planar valve 10 is configured to drive the drive element 18 to rotate via a transmission mechanism 14, such as a transmission gear, according to a purification-softening control command. This drives the moving valve plate 13 of the planar valve 10 to rotate relative to the fixed valve plate 12, thereby forming a first communication channel 1001 that communicates with the inner cavity 110 and the fifth opening 1105 of the valve body 11 of the planar valve 10, a second communication channel 1002 that communicates with the second opening 1102 and the seventh opening 1107 of the valve body 11, and a third communication channel 1003 that communicates with the sixth opening 1106 and the eighth opening 1108 of the valve body 11. This allows raw water to flow from the inner cavity 110 of the valve body 11, through the first communication channel 1001 formed by the planar valve 10, and through the valve body 11's... The fifth opening 1105 and the first connecting opening 201 of the purification device 20 flow into the purification device 20. After the raw water is purified by the purification device 20, the purified water flows out from the second connecting opening 202 of the purification device 20. Then the purified water is divided into two paths. One path of purified water flows into the softening tank 31 through the first conducting opening 301 and is softened to obtain softened water. The softened water flows out from the second conducting opening 302 of the softening tank 31, and then through the seventh opening 1107 of the valve body 11 and the second connecting channel 1002 of the plane valve 10. Finally, it flows out through the second opening 1102 of the valve body 11 and is supplied to the user with softened water. The other path of purified water flows through the sixth opening 1106 of the valve body 11 and the third connecting channel 1003 of the plane valve 10. Finally, it flows out through the eighth opening 1108 of the valve body 11 and is supplied to the user with purified water.According to a backwash control command for a softened filter element, the drive element 18 is driven to rotate via the transmission mechanism 14, such as a transmission gear, to drive the moving valve plate 13 of the planar valve 10 to rotate relative to the fixed valve plate 12, thereby forming a fourth communication channel 1004 that communicates with the inner cavity 110 and the seventh opening 1107 of the valve body 11 of the planar valve 10, and a second communication channel 1004 that communicates with the sixth opening 1106 of the valve body 11 and the ninth opening 1109 of the planar valve 10. The five-way connecting channel 1005 allows raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, then through the fourth connecting channel 1004 formed by the planar valve 10 into the seventh opening 1107, and then through the second conducting opening 302 of the softening tank 31 into the softening tank 31. After backwashing the softening material (or water treatment material), such as softening resin, in the softening tank 31, the resulting sewage or wastewater flows from the first opening 1005 of the softening tank 31 into the inner cavity 110 of the valve body 11. The water flows out through the opening 301, then through the sixth opening 1106 of the valve body 11 into the fifth connecting channel 1005 of the planar valve 10, and then out through the ninth opening 1109 of the planar valve 10. Simultaneously, a sixteenth connecting channel 10016 is formed, connecting to the second opening 1102 of the valve body 11 and the inner cavity 110, respectively, to allow raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, and then through the sixth opening 1109 of the planar valve 10. The sixteenth connecting channel 10016 flows into the second opening 1102 of the valve body 11 to provide raw water to the user. It also forms a seventeenth connecting channel 10017 that is connected to the eighth opening 1108 of the valve body 11 and the inner cavity 110, respectively, so as to allow raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, and then flow into the eighth opening 1108 of the valve body 11 through the seventeenth connecting channel 10017 to provide raw water to the user.According to a backwash control command from a purification device, the drive element 18 is driven to rotate via the transmission mechanism 14, such as a transmission gear, to drive the moving valve plate 13 of the planar valve 10 to rotate relative to the fixed valve plate 12. This forms a sixth communication channel 1006 that communicates with the inner cavity 110 of the valve body 11 and the sixth opening 1106, and a seventh communication channel 1007 that communicates with the fifth opening 1105 of the valve body 11 and the ninth opening 1109 of the planar valve 10. This allows raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, then through the sixth communication channel 1006 into the sixth opening 1106, and then into the second communication opening 202 of the purification device 20. After backwashing the water treatment materials or mechanisms in the purification device 20, the water flows out from the first communication opening 201 of the purification device 20 and then flows through the valve body. Water flows into the seventh connecting channel 1007 through the fifth opening 1105 of the valve body 11, and then flows out through the ninth opening 1109 of the planar valve 10. Simultaneously, a sixteenth connecting channel 10016 is formed, communicating with both the second opening 1102 and the inner cavity 110 of the valve body 11. This allows raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, and then flow through the sixteenth connecting channel 10016. The valve body 11's second opening 1102 provides raw water to the user. It also forms a seventeenth connecting channel 10017, which communicates with both the eighth opening 1108 and the inner cavity 110 of the valve body 11. This allows raw water to flow from the first opening 1101 into the inner cavity 110 of the valve body 11, and then through the seventeenth connecting channel 10017 into the eighth opening 1108, providing raw water to the user.

[0194] As shown in the attached image. Figures 8A to 14 and Figures 16A to 16GAs shown, according to a preferred embodiment of the water treatment machine, the control device 16 of the planar valve 10 is further configured to drive the drive element 18 to rotate via the transmission mechanism 14, such as a transmission gear, according to a softening filter regeneration control command, so as to drive the moving valve plate 13 of the planar valve 10 to rotate relative to the fixed valve plate 12, thereby forming an eighth communication channel 1008 that communicates with the inner cavity 110 and the third opening 1103 of the valve body 11, and a ninth communication channel 1004 that communicates with the seventh opening 1107 and the fourth opening 1104 of the valve body 11. 009 and a tenth connecting channel 10010, which is connected to the sixth opening 1106 of the valve body 11 and the ninth opening 1109 of the plane valve 10 respectively, allow raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, then flow through the eighth connecting channel 1008 into the third opening 1103, and then into the ejection outlet 321 of the ejector 32. After being ejected by the ejector 32 and mixed with the liquid from the brine tank 33, the water flows through the injection inlet 322 of the ejector 32 into the fourth opening 1104 of the valve body 11. Then, it flows through the ninth connecting channel 1009 into the seventh opening 1107, enters the second conductive opening 302 of the softening tank 31, regenerates the softening resin in the softening tank 31 by countercurrent flow, and then flows out from the first conductive opening 301. It then flows through the sixth opening 1106 of the valve body 11 into the tenth connecting channel 10010, and then flows out from the ninth opening 1109 of the planar valve 10. Simultaneously, a sixteenth connecting channel 10016 is formed, which is connected to the second opening 1102 of the valve body 11 and the inner cavity 110, respectively, to allow raw water to flow from the valve body 11... The first opening 1101 allows water to flow into the inner cavity 110 of the valve body 11, and then into the second opening 1102 of the valve body 11 through the sixteenth connecting channel 10016, providing raw water to the user. A seventeenth connecting channel 10017 is also formed, which is connected to the eighth opening 1108 of the valve body 11 and the inner cavity 110, respectively, to allow raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, and then into the eighth opening 1108 of the valve body 11 through the seventeenth connecting channel 10017, providing raw water to the user.According to a forward wash control command for a softening filter cartridge, the drive element 18 is driven to rotate via the transmission mechanism 14, such as a transmission gear, to drive the moving valve plate 13 of the planar valve 10 to rotate relative to the fixed valve plate 12. This forms an eleventh communication channel 10011 that communicates with the inner cavity 110 of the valve body 11 and the sixth opening 1106, and a twelfth communication channel 10012 that communicates with the seventh opening 1107 of the valve body 11 and the ninth opening 1109 of the planar valve 10. This allows raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, then through the eleventh communication channel 10011 into the sixth opening 1106, and then into the first conducting opening 301 of the softening tank 31. After forward rinsing the water treatment materials or mechanism in the softening tank 31, the water flows out from the second conducting opening 302 of the softening tank 31 and then flows through the valve. Water flows into the twelfth connecting channel 10012 through the seventh opening 1107 of the body 11, and then flows out through the ninth opening 1109 of the planar valve 10. Simultaneously, a sixteenth connecting channel 10016 is formed, communicating with both the second opening 1102 and the inner cavity 110 of the valve body 11, allowing raw water to flow from the first opening 1101 of the valve body 11 into the inner cavity 110 of the valve body 11, and then through the sixteenth connecting channel 10016. The second opening 1102 of the valve body 11 provides raw water to the user. It also forms an eighteenth connecting channel 10018, which communicates with both the eighth opening 1108 and the inner cavity 110 of the valve body 11. This allows raw water to flow from the first opening 1101 into the inner cavity 110 of the valve body 11, and then through the eighteenth connecting channel 10018 into the eighth opening 1108 of the valve body 11, providing raw water to the user.

After being treated by the water treatment materials or mechanisms of the purification device 20, it flows out from the second connecting opening 202 of the purification device 20. The outflowing purified water is then divided into two paths. One path of purified water flows into the first conducting opening 301 of the softening tank 31, and then flows through the softening tank 31.
