Water softeners are equipped with control valves to allow them to operate in multiple different modes. However, the water circuit design of the valve body in existing technologies is relatively complex, with the brine intake and backwash water circuits being quite dispersed. This increases the size of the water softener valve, raises production costs, and reduces economic efficiency. Summary of the Invention

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0069] The following is combined with Figures 1-18 The valve body, soft water valve, and soft water machine of the present invention will be described in accordance with embodiments of the present invention.

[0070] Reference Figure 11 According to an embodiment of the present invention, a water softener includes a water softener valve, a resin assembly 710, and a brine suction and waste discharge device 720. The resin assembly 710 is provided with a water passage component 711 for water flow. One side of the brine suction and waste discharge device 720 is connected to the water passage component 711, and the other side of the brine suction and waste discharge device 720 is connected to the water softener valve.

[0071] Through the above design, the water passage component 711 on the resin component 710 allows water to flow through the resin component 710 during the softening process, removing hardness ions from the water. The brine suction and sewage discharge device 720 is connected to the water passage component 711 on one side, and its function is to flush and discharge the resin component 710 with brine after it becomes saturated, so as to restore the softening capacity of the resin component 710. The brine suction and sewage discharge device 720 is connected to the softening water valve on the other side, which is responsible for controlling the entry and exit of softened water and brine, thereby realizing the normal operation of the water softener. The above design can effectively soften water quality, reduce hardness components in water, and improve water quality.

[0072] It should be noted that, in some embodiments of the present invention, the water softener also includes a brine tank A, and the operation of the water softener valve enables the water softener to have a service state, a brine intake state, a bypass state, a backwash state, a water replenishment state, a slow wash state, and a mixed water state.

[0073] It is understandable that, referring to reference Figure 1 , Figure 3 as well as Figures 8 to 10 According to an embodiment of the present invention, a soft water valve includes a valve body, a fixed plate 300, a movable plate 400, and a drive mechanism.

[0074] Specifically, refer to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 According to an embodiment of the present invention, a valve body for a soft water valve includes a valve seat 100 and a support body 200. The valve seat 100 is provided with a chamber 110, an inlet channel 120, an outlet channel 130, a brine suction channel 140, and a backwash channel 150. The inlet channel 120 is connected to the chamber 110. The support body 200 is disposed in the chamber 110 and connected to the valve seat 100. The support body 200 is uniformly provided with a plurality of regions along its circumferential direction. One of the regions is provided with a brine suction chamber 210 and a backwash chamber 220. The brine suction chamber 210 and the backwash chamber 220 are distributed at intervals within the region. The brine suction chamber 210 is connected to the brine suction channel 140, and the backwash chamber 220 is connected to the backwash channel 150.

[0075] According to an embodiment of the present invention, the valve body for a soft water valve has the following advantages: First, the brine suction chamber 210 and the backwash chamber 220 are spaced apart in the same area, which helps to reduce the number of other chambers, making the structure more compact and the valve body smaller in radial dimension, thereby reducing the volume of the soft water valve, reducing production costs, and improving economic efficiency. Second, since multiple chambers are concentrated on the support body 200, the overall structure is more compact, and the evenly distributed area can increase the stability and balance of the entire support body 200.

[0076] Specifically, refer to Figure 1 and Figure 2 In this embodiment of the invention, the volume of the brine suction chamber 210 is smaller than the volume of the backwash chamber 220. This arrangement is designed to accommodate both the brine suction flow rate and the backwash flow rate, resulting in a relatively reasonable structure.

[0077] It should be noted that, in this embodiment of the invention, the brine suction chamber 210 is used to treat the salt water during the brine suction state. Because the salt concentration in the salt water is high, both the brine suction chamber 210 and the corresponding fixed brine suction orifice 310 typically have small volumes to allow for a more thorough brine suction process and improve the water softener's treatment efficiency. The backwash chamber 220 and the fixed backwash orifice 320 are used to clean the water softener. Their main function is to flush the softening resin assembly 710 with water flow, removing impurities and contaminants to maintain the water softener's cleanliness and high efficiency. Since the backwash process requires a large water flow and pressure, its volume is typically large to allow for faster removal of contaminants and impurities. Therefore, by setting different volumes for the brine suction chamber 210 and the backwash chamber 220, the water softener can achieve a more efficient water treatment and cleaning process, improving its performance and lifespan.

[0078] Specifically, refer to Figures 1 to 3 In this embodiment of the invention, the brine suction chamber 210 and the backwash chamber 220 are distributed at intervals along the radial direction of the support 200, making reasonable use of space and resulting in a compact structure that effectively enhances the structural stability of the soft water valve. The uniform layout of the brine chamber and the backwash chamber 220 helps to balance the internal pressure and center of gravity of the soft water valve.

[0079] Specifically, refer to Figures 1 to 3 In this embodiment of the invention, the brine suction chamber 210 is closer to the center line H of the support body 200 than the backwash chamber 220. This can be understood as the brine suction chamber 210 being located closer to the inside of the support body 200, and the backwash chamber 220 being located closer to the outside of the support body 200. With this arrangement, the brine suction flow rate is relatively small compared to the backwash flow rate, which is beneficial for manufacturing and processing, and facilitates the operation of the soft water valve.

[0080] Specifically, refer to Figures 1 to 3In this embodiment of the invention, the cross-section of the brine suction chamber 210 is fan-shaped, and the cross-section of the backwash chamber 220 is arc-shaped. The central angle of the fan-shaped brine suction chamber 210 and the arc angle of the backwash chamber 220 are equal, which helps to reduce the number of other chambers, making the structure more compact and the valve body smaller in radial dimension, thereby helping to reduce the volume of the soft water valve.

[0081] It should be noted that the central angle of the sector of the brine suction chamber 210 can be understood as the angle corresponding to the arc length of the area occupied by the brine suction chamber 210 on the radial section of the support body 200, which is the first radian θ1; the arc angle of the backwash chamber 220 can be understood as the angle corresponding to the arc length of the area occupied by the backwash chamber 220 on the radial section of the support body 200, which is the second radian θ2, and the first radian θ1 and the second radian θ2 are equal.

[0082] Understandably, referring to Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 In this embodiment, the valve seat 100 is further provided with an inlet channel 160 and an outlet channel 170, both of which are connected to the resin assembly 710.

[0083] Understandably, referring to Figures 1 to 3 In this embodiment of the invention, the remaining areas are respectively provided with an inlet chamber 230, an outlet chamber 240, a bypass chamber 250, and a diversion chamber 260. A portion of the structure of the inlet chamber 230 is located in one area, and another portion of the structure of the inlet chamber 230 is located in another adjacent area. A portion of the structure of the diversion chamber 260 is located at the center of the support 200, and another portion of the structure of the diversion chamber 260 is located in one of the areas. The diversion chamber 260 and the inlet chamber 230 are located in two different areas. The above design can provide a larger inlet flow rate and realizes water diversion, improves water inlet efficiency, and optimizes space utilization.

[0084] It should be noted that, referring to Figures 1 to 3 In this embodiment of the invention, the diversion chamber 260 and the brine suction chamber 210 are both located on the peripheral wall away from the support body 200, while the water inlet chamber 230, the water outlet chamber 240, the backwash chamber 220 and the bypass chamber 250 are all located on the peripheral wall close to the support body 200.

[0085] It should be noted that, in this embodiment of the invention, the bypass cavity 250 is connected to the outlet channel 130; wherein, the bypass cavity 250 and the outlet channel 130 are arranged adjacent to each other. By arranging the bypass cavity 250 and the outlet channel 130 adjacently, it means a shorter connection distance, which allows for a shorter path when water flows from the bypass cavity 250 to the outlet channel 130, further resulting in a narrower valve seat 100, thereby reducing the volume of the valve body, reducing resistance loss, and making more efficient use of space; secondly, the aforementioned functional chambers 110 of the inlet cavity 230, outlet cavity 240, brine suction cavity 210, backwash cavity 220, diversion cavity 260, and bypass cavity 250 are integrated into the support body 200, which avoids the use of independent components, thereby further reducing the overall volume.

[0086] It is understood that, in this embodiment of the invention, a connecting hole is provided between one side wall of the bypass cavity 250 and one side wall of the water outlet channel 130. Since the connecting hole between the bypass cavity 250 and the water outlet channel 130 can directly connect the two, the use of additional pipe connections is avoided, which can reduce the risk of leakage and failure at the pipe connection and improve the compactness of the entire soft water valve structure.

[0087] Specifically, refer to Figure 1 and Figure 3 In this embodiment, the support body 200 has a circular cross-section, with multiple regions distributed in a fan shape. The circular cross-section provides more uniform support force, increasing the strength and rigidity of the support body 200. Simultaneously, the circular geometry avoids excessive local pressure, reducing the risk of deformation and damage to the support body 200. Furthermore, the fan-shaped distribution allows for a more rational arrangement of multiple cavities, enabling the moving plate 400 to achieve the relevant water circuit state with a single rotation relative to the support body 200. This results in a more compact structure, more convenient operation, and a reduction in the size of the soft water valve. It should be noted that the centerline H of the support body 200 coincides with its circular center.

[0088] specifically refer to Figure 1 and Figure 3In this embodiment, the volumes of the brine suction chamber 210 and the backwash chamber 220 are both smaller than the volume of the bypass chamber 250. By controlling the volumes of the brine suction chamber 210 and the backwash chamber 220 to be smaller relative to the bypass chamber 250, fluid balance can be achieved. This ensures that the flow ratio of fluid between the brine suction chamber 210 and the backwash chamber 220 is appropriate during brine suction and backwashing, avoiding the impact on system performance and effectiveness due to uneven flow. The larger volume of the bypass chamber 250 provides a larger flow channel, reducing fluid resistance and allowing for faster flow rates. Conversely, the smaller volumes of the brine suction chamber 210 and the backwash chamber 220 limit the fluid flow rate, which is beneficial for the operation and effectiveness of brine suction and backwashing. Furthermore, by setting different volumes, different functions can be concentrated in their respective chambers 110. The brine suction and backwashing operations are carried out in the relatively small chamber 110, while the bypass water outlet is achieved through the larger bypass chamber 250. This can improve the flexibility and efficiency of operation, while avoiding interference and crossover between functions, making reasonable use of space, and helping to reduce the size of the valve body.

[0089] It is understandable that the support body 200 and the valve seat 100 are an integral structure. This integrated design and manufacturing process provides higher structural strength and stability, reduces connection points between components, and thus lowers the risk of loosening or wear. Alternatively, the support body 200 and valve seat 100 can be separate structures, and can be fixedly connected by snap-fit, bolting, welding, or other methods.

[0090] Understandably, referring to Figure 1 and Figure 3 In this embodiment, a blocking part 270 is provided on one region of the support body 200. The blocking part 270 and a part of the structure of the water inlet chamber 230 are located in the same region. The blocking part 270 is located between the bypass chamber 250 and the water inlet chamber 230. The blocking part 270 can isolate the chambers and prevent water flow from passing between different chambers. It avoids water leakage when the bypass chamber 250 is not needed. For example, when producing soft water in service mode, the blocking part 270 helps to extend the distance between the bypass chamber 250 and the water inlet chamber 230.

[0091] Specifically, refer to Figure 1 and Figure 3 In this embodiment of the invention, the blocking part 270 is provided with a first process cavity 280, which is beneficial for uniform wall thickness, convenient for mold opening, and avoids shrinkage of the support body 200.

[0092] Specifically, refer to Figure 1 and Figure 3A second process cavity 270 is provided in one area of ​​the support body 200. The second process cavity 270 and a part of the structure of the flow distribution cavity 260 are located in the same area. This makes rational use of the spatial structure of the support body 200, which is conducive to uniform wall thickness, convenient mold opening, and avoids shrinkage of the support body 200.

[0093] Understandably, referring to Figure 1 and Figure 3 In this embodiment of the invention, both the first process cavity 280 and the second process cavity 270 extend along the thickness direction of the support body 200. The portion of the support body 200 located outside its center is divided into six equal parts along the circumferential direction. A portion of the diversion cavity 260 is a central groove, and another portion is a fan-shaped groove. The central groove is located at the center of the support body 200. A portion of the structure of the water inlet cavity 230 occupies one equal part, and the other portion of the structure of the water inlet cavity 230 shares one equal part with the first process cavity 280. The backwash chamber 220 and the brine suction chamber 210 share an equal portion, the bypass chamber 250 shares an equal portion, the fan-shaped trough and the second process chamber 270 share an equal portion, and the water outlet chamber 240 shares an equal portion. Through the above structure, the support body 200 is evenly divided, which can achieve load balance of the support body 200. This helps to ensure that each part is subjected to the same pressure, reduces the load on individual parts, thereby reducing the possibility of deformation and stress concentration, improving the stability and safety of the structure, and making the wall thickness of the support body 200 relatively uniform.

[0094] Specifically, refer to Figure 1 and Figure 3 In this embodiment, the central angles of the bypass cavity 250, the water outlet cavity 240, the brine suction cavity 210, the arc angle of the backwash cavity 220, the central angles of the first process cavity 280, the second process cavity 270, the central angle of the fan-shaped groove of the diversion cavity 260, and a portion of the central angles of the water inlet cavity 230 are all equal. This further facilitates the relatively uniform wall thickness of the support body 200, making it easier to manufacture and process, and convenient for demolding.

[0095] Understandably, referring to 9 and Figure 10In this embodiment of the invention, a fixed plate 300 is disposed within a chamber 110 and is fixed relative to a support 200; a movable plate 400 is disposed within a chamber 110 and is rotatable relative to a support 200; a drive mechanism is disposed on a valve seat 100 and is connected to the movable plate 400 in a transmission manner; when the movable plate 400 rotates relative to the support 200, it switches between multiple water circuit working states; wherein, the fixed plate 300 is disposed between the support 200 and the movable plate 400, and the fixed plate 300 and the movable plate 400 abut against each other. Different water circuits can be selected as needed, such as service water circuit, brine intake water circuit, bypass water circuit, backwash water circuit, and makeup water circuit. The moving plate 400 is driven by the drive mechanism. The moving plate 400 cooperates with the support body 200 and the fixed plate 300. The moving plate 400 can rotate relative to the support body 200, and can be adjusted and controlled as needed. By switching water circuits, different functions and uses can be achieved to meet different needs, making the soft water valve flexible and adaptable to different water qualities and usage environments. Secondly, the cooperation between the moving plate 400 and the fixed plate 300 can prevent the support body 200 from being worn, and improve the sealing performance and stability under different water circuit conditions.

[0096] It should be noted that the radial shape of the fixing plate 300 is adapted to the radial shape of the support 200.

[0097] Understandably, referring to Figure 7 , 9 and Figure 10 In this embodiment of the invention, a sealing structure 500 is provided between the fixed plate 300 and the support body 200. One side of the sealing structure 500 abuts against the fixed plate 300, and the other side of the sealing structure 500 abuts against the support body 200, thereby improving the sealing performance of the two.

[0098] Specifically, the sealing structure 500 is a sealing gasket, which can provide a certain friction between the support 200 and the fixed plate 300, which helps to prevent the fixed plate 300 from rotating relative to the support 200 and improves working stability.

[0099] It is understood that in this embodiment of the invention, both the moving plate 400 and the fixed plate 300 are made of ceramic. The use of ceramic components provides excellent corrosion resistance, allowing for long-term stable use in various acidic and alkaline environments. This effectively resists corrosion and extends service life. Furthermore, because the surface of ceramic materials is smooth and does not easily adhere to substances, they are relatively less susceptible to contamination during operation, reducing cleaning frequency, lowering maintenance costs, and ensuring the continuous and efficient operation of the water softener. Additionally, ceramic materials have high hardness and strength, allowing them to withstand significant pressure and impact, enabling the ceramic components to operate stably in the water softener valve and preventing deformation or breakage. Of course, in some embodiments, the moving plate 400 and the fixed plate 300 can also be made of other materials, such as plastic.

[0100] Understandably, referring to Figure 1 , Figure 3 and Figure 4 In this embodiment of the invention, the outer peripheral wall of the fixed plate 300 is provided with a positioning structure, which is arranged radially. The inner wall of the chamber 110 of the valve seat 100 is provided with a fixing structure. The positioning structure and the fixing structure are engaged to restrict the circumferential rotation of the fixed plate 300 relative to the support body 200, thereby improving the reliability and stability of the soft water valve operation.

[0101] Specifically, refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, the positioning structure includes a first positioning part 811, a second positioning part 812, and a third positioning part 813. The first positioning part 811, the second positioning part 812, and the third positioning part 813 are spaced apart on the outer peripheral wall of the main body of the positioning plate 300. The fixing structure includes a first fixing part 821, a second fixing part 822, and a third fixing part 823. The first positioning part 811 and the first fixing part 821 are engaged, the second positioning part 812 and the second fixing part 822 are engaged, and the third positioning part 813 and the third fixing part 823 are engaged. The second positioning part 812 and the third positioning part 813 are all configured as positioning grooves, and the first fixing part 821, the second fixing part 822, and the third fixing part 823 are all configured as fixing protrusions. The fixing protrusions are engaged with the positioning grooves. The structure is simple, easy to disassemble, and plays a role in preventing mistakes.

[0102] It should be noted that, referring to Figure 1 , Figure 3 and Figure 4 The circumferential dimensions of the first positioning part 811, the second positioning part 812, and the third positioning part 813 are inconsistent, as are the circumferential dimensions of the first fixing part 821, the second fixing part 822, and the third fixing part 823. This further prevents incorrect or reverse installation and improves the error-proofing effect. Specifically, the groove widths of the positioning grooves of the first positioning part 811, the second positioning part 812, and the third positioning part 813 are inconsistent.

[0103] It is understood that in this embodiment, the first positioning part 811, the second positioning part 812 and the third positioning part 813 are integrally injection molded with the fixed plate 300. The integral injection molding design can reduce the number of parts of the soft water valve and simplify the structure of the entire soft water valve, thereby reducing production costs and reducing the risk of malfunction during use.

[0104] It is understood that, in the embodiments of the present invention, reference is made to... Figure 9 , Figure 10 and Figure 11The drive mechanism includes a drive motor 610, a drive gear 620, a driven gear 630, and a transmission shaft 640. The drive motor 610 is mounted on the valve seat 100. The drive gear 620 is fixedly connected to the output shaft of the drive motor 610. The driven gear 630 meshes with the drive gear 620 for transmission. One end of the driven gear 630 is fixedly connected to the transmission shaft 640, and the moving disc 400 is connected to the other end of the transmission shaft 640 for transmission. The drive motor 610 is fixedly connected to the drive gear 620 through its output shaft, transmitting the rotational torque of the drive motor 610 to the drive gear 620. The meshing of the driven gear 630 with the drive gear 620 effectively converts the energy input from the drive motor 610 into the kinetic energy of the transmission shaft 640, thereby driving the moving disc 400 to rotate. The meshing transmission between the drive gear 620 and the driven gear 630 provides a stable transmission ratio and transmission efficiency, ensuring stability and reliability during transmission.

[0105] Specifically, in this embodiment, referring to Figure 9 , Figure 10 and Figure 11 The aforementioned drive mechanism also includes a plug 650 and a control plate 660. The moving plate 400 and the transmission shaft 640 are engaged, and the plug 650 is sleeved on the transmission shaft 640. The plug 650 abuts against the upper side of the transmission shaft 640 to restrict the movement of the transmission shaft 640 away from the moving plate 400. The control plate 660 is provided with multiple sensing positions, and the driven gear 630 is provided with a sensing element that senses and engages with the sensing positions. By rotating the driven gear 630 relative to the control plate 660, the sensing positions and sensing elements sense and engage, thereby switching the water circuit state.

[0106] Understandably, referring to Figure 11 In this embodiment of the invention, the resin assembly 710 includes two resin tanks arranged side by side, both of which are connected to the water passage component 711 to realize the entry and exit of liquid from the resin tanks; referring to Figures 1-2, the resin tank includes a tank body 712, a central tube 713 disposed in the tank body 712, and a resin body 714 surrounding the central tube 713.

The water outlet chamber 240 is connected to the space where the resin body 714 is located outside the central tube 713 through the tank inlet channel 160.

[0107] It is understood that in this embodiment, the soft water valve also includes a valve cover 900, which is detachably connected to the valve seat 100 and covers the valve cavity. The valve cover 900 has a simple structure and good protection performance.

[0108] It should be noted that, referring to Figure 8 and Figure 10In this embodiment of the invention, the valve seat 100 is provided with a check valve 180 and a flow meter 190. The water outlet channel 130 and the tank outlet channel 170 are connected by the check valve 180, so that the water outlet channel 170 and the water outlet channel 130 are unidirectionally connected, and the liquid is prevented from flowing to the tank outlet channel 170 through the bypass cavity 250. The orthogonal projections of the brine suction channel 140 and the backwashing cavity 220 overlap, so as to realize the control of multiple water paths, making the design of the support body 200 more reasonable and helping to reduce the size of the soft water valve.

[0109] Understandably, referring to Figures 11 to 18 In this embodiment, the brine suction and wastewater discharge device 720 includes an ejector assembly 721, a check ball assembly 722, and a wastewater discharge assembly 723. The ejector assembly 721 is connected to the brine tank A for absorbing saturated brine. One end of the ejector assembly 721 is connected to the brine suction channel 140. One end of the check ball assembly 722 is connected to the other end of the ejector assembly 721. The other end of the check ball assembly 722 is connected to the central tube 713 of the resin assembly 710 for on / off connection. The wastewater discharge assembly 723 is connected to the upper part of the resin tank for discharging wastewater.

[0110] Specifically, in this embodiment, referring to Figure 4 The fixed plate 300 is provided with a fixed brine suction hole 310, a fixed backwash hole 320, a fixed water inlet hole 330, a fixed water outlet hole 340, a fixed bypass hole 350, a fixed diversion hole 360, a first process hole 370, and a second process hole 380; (Refer to...) Figure 7 The sealing structure 500 has corresponding sealed water inlet 530, sealed water outlet 540, sealed brine suction hole 510, sealed backwash hole 520, sealed bypass hole 550, sealed diversion hole 560, sealed first process hole 570, and sealed second process hole 580. The water inlet chamber 230, fixed water inlet 330, and sealed water inlet 530 correspond to each other; the water outlet chamber 240, fixed water outlet 340, and sealed water outlet 540 correspond to each other; the brine suction chamber 210, fixed brine suction hole 310, and sealed brine suction hole 510 correspond to each other; and the backwash chamber 2... 20. The fixed backwash hole 320 and the sealed backwash hole 520 correspond to each other; the bypass cavity 250, the fixed bypass hole 350 and the sealed bypass hole 550 correspond to each other; the diversion cavity 260, the fixed diversion hole 360 ​​and the sealed diversion hole 560 correspond to each other; the first process cavity 280, the first process hole 370 and the first sealed process hole 570 correspond to each other; the second process cavity 270, the second process hole 380 and the second sealed process hole 580 correspond to each other. Among them, the sealing structure 500 has sealing ribs between each hole to restrict the communication between adjacent holes.

[0111] Understandably, referring to Figure 5 and Figure 6In this embodiment of the invention, the movable disk 400 is provided with a movable diversion groove 410, a first inlet 420, a second inlet 440, and a third inlet 440. The movable disk 400 is also provided with an annular groove 450 and multiple water inlet grooves 460. The annular groove 450 is arranged around the center of the movable disk 400, and the multiple water inlet grooves 460 are spaced apart and arranged around the annular groove 450. The water inlet grooves 460 are connected to the annular groove 450. The first inlet 420, the second inlet 440, and the third inlet 440 are all connected to the annular groove 450. With the above structure, when the movable disk 400 rotates relative to the support body 200, the movable diversion groove 410, the first inlet 420, the second inlet 440, and the third inlet 440 correspond to different areas on the support body 200, thereby enabling the water softener to have service mode, brine suction mode, bypass mode, backwash mode, and water replenishment mode. The structure is reasonable and the water intake effect is good.

[0112] It should be noted that, referring to Figure 5 and Figure 6 In this embodiment of the invention, the moving disk 400 is further provided with a plurality of blind holes. The plurality of blind holes, the first through-hole 420, the second through-hole 440 and the third through-hole 440 are arranged around the center line N of the moving disk 400 to improve the structural strength of the moving disk 400. The layout is reasonable, easy to manufacture, and helps to reduce the weight and material of the moving disk 400.

[0113] It should be noted that the center line N of the moving disk 400 can be understood as follows: in this embodiment, the outer contour of the moving disk 400 is circular, and the center line N of the moving disk 400 coincides with the center of the circular moving disk 400.

[0114] Specifically, in this embodiment, the outer wall of the support 200 and the inner wall of the chamber 110 of the valve seat 100 are spaced apart to form a water inlet gap. The water inlet gap is arranged around the support 200 and is connected to the water inlet cavity 230 of the support 200. The water inlet gap is also connected to the water inlet groove 460 of the moving plate 400. Raw water reaches the water inlet gap through the water inlet channel 120, passes through the multiple water inlet grooves 460 of the moving plate 400 to reach the annular groove 450, and enters the water inlet cavity 230 through the annular groove 450. This not only disperses the water inlet pressure, but also allows the moving plate 400 and the fixed plate 300 to be pressed together by water pressure.

[0115] The working process of the water softener according to an embodiment of the present invention is described below:

[0116] When the water softener is in service and producing water, refer to... Figure 12The first inlet 420, the fixed outlet 340, and the outlet cavity 240 are connected to each other. The second inlet 440, the second process hole 380, and the second process cavity 270 are connected to each other. The third inlet 440 is connected to a portion of the structure of the inlet cavity 230. Another portion of the structure of the inlet cavity 230 corresponds to a portion of the blind hole of the moving plate 400. The remaining cavities and water holes are closed. The blocking part 270, the fixed plate 300, and the moving plate 400 are in close contact with each other. Therefore, the raw water flows through the inlet channel 12. The resin flows from the inlet gap and inlet groove 460 to the first outlet 420 via the multiple inlet grooves 460 of the moving plate 400, through the fixed outlet hole 340 and outlet cavity 240 to the tank inlet channel 160, and then through the water circuit component 711, the upper part of the resin tank and the resin body 714 to the lower part of the resin tank in the space where the resin body 714 is located outside the central tube 713. After softening, it flows through the central tube 713 to the tank outlet channel 170, and through the check valve 180 to the outlet channel 130.

[0117] When the water softener is in brine extraction mode, refer to Figure 13 A portion of the structure of the first port 420 is connected to the fan-shaped groove of the fixed diversion hole 360 ​​and the diversion cavity 260. Another portion of the structure of the first port 420 is connected to the second process hole 380 and the second process cavity 270. The second port 440 and the third port 440 are both connected to the corresponding fixed inlet hole 330 and inlet cavity 230. A portion of the structure of the moving diversion channel 410 is connected to the fixed brine suction hole 310 and brine suction cavity 210. Another portion of the structure of the moving diversion channel 410 is connected to the fixed bypass hole 350 and bypass cavity 250. Raw water enters the chamber 110 of the valve seat 100 through the inlet channel 120 and fills the inlet cavity 230 and the diversion cavity 260 through the inlet gap and the inlet groove 460. After the diversion chamber 260 of the support body 200 is filled with raw water, the raw water is divided into two streams through the dynamic diversion channel 410. One stream of raw water reaches the brine suction chamber 210, and the other stream of raw water reaches the bypass chamber 250. The ejector assembly 721 generates negative pressure to draw in the brine and mixes the brine and raw water into a mixed brine solution. At this time, the check ball assembly 722 opens, and the brine reaches the central pipe 713 through the ejector assembly 721 and the check ball assembly 722. The brine is then regenerated by contacting the resin body 714 through the central pipe 713 and the lower part of the resin tank outside the central pipe 713. Finally, the wastewater is discharged through the upper part of the resin tank and the drain assembly 723. The raw water in the other bypass chamber 250 is discharged through the water outlet channel 130, thus achieving water supply during regeneration.

[0118] When the water softener is in bypass mode, refer to Figure 14The first port 420 and the second port 440 are connected to the fixed inlet port 330 and the inlet chamber 230 respectively. The third port 440 is connected to the fixed bypass port 350 and the bypass chamber 250 respectively. The other chambers and water inlets are closed. Raw water enters the chamber 110 of the valve seat 100, fills the inlet chamber 230 and the inlet gap, and reaches the bypass chamber 250 through multiple inlet grooves 460 and the third port 440. After passing through the bypass chamber 250, it is transported to the outlet channel 130 to realize water supply.

[0119] When the water softener is in backwash mode, refer to Figure 15 The first port 420 is connected to the fixed water inlet 330 and the water inlet chamber 230, the second port 440 is connected to the bypass chamber 250, and the third port 440 is connected to the fixed backwash port 320 and the backwash chamber 220. The other chambers and water inlets are closed. Raw water enters the water inlet channel 120 and enters the chamber 110 of the valve seat 100. It is divided into two streams of raw water through the water inlet gap and multiple water inlet grooves 460. One stream of raw water enters the backwash chamber 220 and enters the central tube 713 of the resin assembly 710 through the backwash channel 150. It then contacts the bottom of the resin body 714 outside the resin tank on the outside of the central tube 713 for backwashing. The other stream of raw water reaches the bypass chamber 250 and flows out through the water outlet channel 130, thus realizing backwash water supply.

[0120] When the water softener is in the water replenishment state, refer to Figure 16 A portion of the structure of the first port 420, the brine suction hole, and the brine suction chamber 210 are connected. The first port 420 and another portion of the structure are connected to the backwash chamber 220. The second port 440 is connected to the outlet chamber 240. The third port 440 is connected to the second process chamber 270. Raw water enters the inlet gap in the chamber 110 of the valve seat 100 through the inlet channel 120, reaches the first port 420 and the brine suction chamber 210 through the inlet groove 460 of the moving plate 400, and reaches the brine tank A for water replenishment through the ejector assembly 721. The raw water reaching the outlet chamber 240 can reach the upper part of the resin tank through the inlet channel 160, be softened by the resin body 714, and reach the central pipe 713 through the lower part of the resin tank. It then reaches the outlet channel 130 through the outlet channel 170 and the check valve 180 to achieve uninterrupted water supply. All other chambers and holes are closed. It should be noted that during the water replenishment state, the ball of the check ball assembly 722 is in the closed position due to the large water pressure at its upper part. Therefore, the water passing through the ejector assembly 721 will not reach the central pipe 713 of the resin assembly 710, and the water passing through the brine suction chamber 210 can only reach the brine tank A.

[0121] When the water softener is in slow wash mode, refer to Figure 17A portion of the structure of the first port 420 is connected to the fan-shaped groove of the fixed diversion hole 360 ​​and the diversion cavity 260. Another portion of the structure of the first port 420 is connected to the second process hole 380 and the second process cavity 270. The second port 440 and the third port 440 are both connected to the corresponding fixed water inlet hole 330 and the water inlet cavity 230. A portion of the structure of the moving diversion channel 410 is connected to the fixed salt suction hole 310 and the salt suction cavity 210. Another portion of the structure of the moving diversion channel 410 is connected to the fixed bypass hole 350 and the bypass cavity 250. All other cavities and holes are closed. Raw water enters the chamber 110 of valve seat 100 through inlet channel 120. It fills inlet chamber 230 and diversion chamber 260 through inlet gap and inlet groove 460. When the diversion chamber 260 of support body 200 is filled with raw water, the raw water is divided into two streams through dynamic diversion groove 410. Since the ejector assembly 721 is disconnected from the brine tank A after the brine is absorbed, one stream of raw water reaches brine suction chamber 210. The check ball assembly 722 opens and reaches central pipe 713 through ejector assembly 721 and check ball assembly 722. It then contacts resin body 714 through central pipe 713 and the lower part of resin tank outside central pipe 713 for slow washing. Finally, the wastewater is discharged through the upper part of resin tank and sewage discharge assembly 723. The other stream of raw water in bypass chamber 250 is discharged through outlet channel 130, realizing uninterrupted water supply.

[0122] When the water softener is in a mixed state, refer to Figure 18 During the water mixing process, the first port 420 of the moving plate 400 and the fixed water outlet 340 and water outlet cavity 240 of the fixed plate 300 are offset at a preset angle to mix the water. A portion of the structure of the fixed diversion hole 360 ​​and diversion cavity 260 is connected to the first port 420. A portion of the structure of the first port 420 is correspondingly connected to a portion of the fixed water outlet 340 and water outlet cavity 240 of the fixed plate 300. Another portion of the structure of the first port 420 is correspondingly connected to another portion of the second process hole 380 and second process cavity 270 of the fixed plate 300. A portion of the structure of the second port 440 is correspondingly connected to another portion of the second process hole 380 and second process cavity 270 of the fixed plate 300. The structures are connected accordingly. Another part of the structure of the second port 440 is connected to a part of the structure of the fixed water inlet 330 and the water inlet chamber 230. The third port 440 is connected to a part of the structure of the fixed water inlet 330 and the water inlet chamber 230. A part of the raw water reaches the chamber 110 of the valve seat 100 through the water inlet channel 120, and then reaches the water outlet chamber 240 through the water inlet gap and the water inlet groove 460. After passing through the water outlet chamber 240 and the tank inlet channel 160, it reaches the area where the resin body 714 of the resin component 710 is located. After being softened, it reaches the check valve 180. Another part of the raw water reaches the backwash chamber 220 and reaches the water outlet through the backwash channel 150. The two parts of water are mixed.

[0123] Understandably, referring to Figure 17 and Figure 18 In this embodiment of the invention, in the slow wash state, the channel between the salt tank A and the jet assembly 721 is closed, so that the resin body 714 is slowly rinsed with the original mixed salt solution and the newly introduced raw water; in the mixed water state, the hardness of the soft water is adjusted.

[0124] It should be noted that, in this embodiment of the invention, since the support body 200 is divided into six equal parts, when the water softener is in the mixing state, during the mixing process, the first port 420 of the moving plate 400 and the fixed water outlet 340 and water outlet cavity 240 of the fixed plate 300 are offset by a preset angle to mix the water. The preset angle range is greater than 0 degrees and less than 60 degrees. For example, the moving plate 400 can rotate to 30 degrees or to 35 degrees to achieve the mixing state.

[0125] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should all be covered within the protection scope of the present invention.
