[0065] Combine the following Figure 1-Figure 17 The fixed plate, the softening valve for a water softener and the water softener according to the embodiments of the utility model are described.

[0066] It is understandable that, referring to Figure 1 and Figure 8 According to an embodiment of the utility model, a fixed plate for a soft water valve includes a fixed plate body 100, and the fixed plate body 100 is provided with at least one hole, wherein the outer peripheral wall of the fixed plate body 100 is provided with at least a positioning structure, and the positioning structure extends radially.

[0067] According to the fixed plate of the embodiment of the utility model, the positioning structure is radially extended and arranged on the outer peripheral wall of the fixed plate body 100, which can achieve precise positioning, improve stability and increase structural strength, and has good assembly stability and high reliability.

[0068] Reference Figure 1 , Figure 5 , Figure 6 , Figure 8 and Fig.10 According to a soft water valve of an embodiment of the utility model, the soft water valve includes a fixed plate and a valve assembly, the valve assembly includes a valve body 200, the valve body 200 is provided with a valve cavity 210, the fixed plate is arranged in the valve cavity 210, and the fixed plate is fixed relative to the valve cavity 210.

[0069] It is understandable that reference Figure 1 , Figure 5 and Figure 6 In an embodiment of the utility model, the valve body 200 of the valve assembly is provided with a fixed structure, and the fixed structure is located in the valve cavity 210; wherein the positioning structure corresponds to the fixed structure to limit the rotation of the fixed disk relative to the valve assembly.

[0070] Through the above design, since a fixing structure and a positioning structure are provided between the fixed plate and the valve body 200 of the valve assembly, the rotation of the fixed plate can be effectively restricted, thereby maintaining the stability and reliability of the soft water valve, preventing the soft water valve from unnecessary rotation or displacement during operation, and ensuring the normal operation of the soft water valve.

[0071] Specifically, refer to Figure 1 In the embodiment of the utility model, the positioning structure includes a first positioning portion 111, a second positioning portion 112 and a third positioning portion 113, and the first positioning portion 111, the second positioning portion 112 and the third positioning portion 113 are arranged at intervals on the outer peripheral wall of the fixed plate body 100. Since the first positioning portion 111, the second positioning portion 112 and the third positioning portion 113 are respectively located at different positions of the fixed plate body 100, multi-directional limiting and stable control of the fixed plate can be achieved. The above design can avoid unnecessary rotation or displacement of the fixed plate during operation, and ensure the stability and reliability of the soft water valve.

[0072] Accordingly, refer to Figure 5 and Figure 6In the embodiment of the utility model, the fixing structure of the valve body 200 includes a first fixing portion 211, a second fixing portion 212 and a third fixing portion 213. The first positioning portion 111 and the first fixing portion 211 are snap-fitted together, the second positioning portion 112 and the second fixing portion 212 are snap-fitted together, and the third positioning portion 113 and the third fixing portion 213 are snap-fitted together. The structure is simple and convenient for disassembly, assembly and maintenance.

[0073] Specifically, refer to Figure 1 , Figure 5 and Figure 6 In the embodiment of the utility model, the first positioning portion 111, the second positioning portion 112 and the third positioning portion 113 are all configured as positioning grooves, and the first fixing portion 211, the second fixing portion 212 and the third fixing portion 213 are all configured as fixing protrusions. The fixing protrusions are snap-fitted with the positioning grooves, and the structure is simple and easy to disassemble. Of course, the first positioning portion 111, the second positioning portion 112 and the third positioning portion 113 are all configured as positioning protrusions, and the first fixing portion 211, the second fixing portion 212 and the third fixing portion 213 are all configured as fixing grooves; the fixing protrusions are snap-fitted with the positioning grooves, and the structure is simple and easy to disassemble, which plays a fool-proof role; or the first fixing portion 211, the second fixing portion 212 and the third fixing portion 213 are partially configured as positioning grooves, and the other part is configured as positioning protrusions.

[0074] Reference Figure 1 , Figure 5 and Figure 6 In the embodiment of the utility model, the circumferential dimensions of the first positioning portion 111, the second positioning portion 112 and the third positioning portion 113 are inconsistent with each other, and the circumferential dimensions of the first fixing portion 211, the second fixing portion 212 and the third fixing portion 213 are inconsistent with each other, which further avoids the mis-installation and reverse installation, and improves the fool-proofing effect. Specifically, the widths of the positioning grooves of the first positioning portion 111, the second positioning portion 112 and the third positioning portion 113 are inconsistent.

[0075] Of course, in some embodiments, the circumferential dimensions of the first positioning portion 111 and the second positioning portion 112 are inconsistent with each other; or, the circumferential dimensions of the first positioning portion 111 and the third positioning portion 113 are inconsistent with each other; or, the circumferential dimensions of the second positioning portion 112 and the third positioning portion 113 are inconsistent with each other.

[0076] Specifically, in the embodiment of the utility model, the thickness of the positioning structure is consistent with the thickness of the fixed disk body 100, that is, the thickness of the first positioning portion 111, the second positioning portion 112 and the third positioning portion 113 are all equal to the thickness of the fixed disk body 100, which can be more conveniently designed and manufactured during the processing, can reduce the adjustment and adaptation during the processing, simplify the production process, improve the processing efficiency, make the overall structure of the soft water valve more balanced and consistent, further enhance the stability and reliability of the soft water valve, prevent uneven stress and deformation caused by thickness differences, and increase the service life and pressure resistance of the soft water valve.

[0077] It can be understood that in the embodiment of the utility model, the positioning structure and the fixed plate body 100 are integrally injection molded. 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. The above design can reduce production costs and reduce the risk of failure of the soft water valve during use.

[0078] It is understandable that, referring to Figure 1 , Figure 5 , Figure 6 , Figure 8 and Fig.10 In the embodiment of the utility model, the valve body 200 is provided with a water inlet channel 220, a water outlet channel 230, a tank inlet channel 240, a tank outlet channel 250, a salt absorption channel 260 and a backwash channel 270. Specifically, in the embodiment of the utility model, the soft water valve further includes a moving disc 300, which is located in the valve cavity 210, and the moving disc 300 is abutted and matched with the fixed disc, and the moving disc 300 is rotatable relative to the fixed disc. When the moving disc 300 rotates relative to the fixed disc, the valve body 200 and the moving disc 300 define a service waterway, a salt absorption waterway, a bypass waterway, a backwash waterway and a water replenishment waterway. Through the water inlet channel 220, the water outlet channel 230, the tank inlet channel 240, the tank outlet channel 250, the salt absorption channel 260 and the backwash channel 270, the soft water valve realizes the control of multiple water channels, and different water channels can be selected according to needs, such as a service water channel, a salt absorption water channel, a bypass water channel, a backwash water channel and a water replenishment water channel, etc.; through the cooperation of the moving disk 300 and the fixed disk, the moving disk 300 is rotatable relative to the fixed disk, and can be adjusted and controlled as needed. By switching the water channels, different functions and uses can be realized to meet different needs, so that the soft water valve has flexibility and can adapt to the needs of different water qualities and usage environments.

[0079] It is understandable that, referring to Fig. 9 and Fig.10 In this embodiment, the soft water valve further comprises a valve cover 500, which is detachably connected to the valve body 200 and covers the valve cavity 210, has a simple structure and good protection performance.

[0080] It is understandable that, referring to Figure 5 , Figure 6 , Figure 8 and Fig.10 In an embodiment of the utility model, the valve body 200 is provided with a supporting structure 410, the supporting structure 410 is located in the valve cavity 210, the fixed plate is arranged on one side of the supporting structure 410, the moving plate 300 is arranged on the other side of the fixed plate, and the radial plane of the supporting structure 410 is provided with a plurality of cavities, and the plurality of cavities are used for switching of waterways; wherein the shapes of the supporting structure 410 and the fixed plate are adapted to each other, and the fixed plate is fixed relative to the supporting structure 410. Through the above-mentioned arrangement, since multiple cavities are concentrated on the support structure 410, the overall structure is more compact. The state of the water path can be switched by simply rotating the moving disk 300 relative to the support structure 410, which is convenient and quick. Secondly, concentrating multiple cavities on the support structure 410 can help reduce the manufacture of additional components. Concentrating the cavities can reduce the number of components, simplify the manufacturing process, and reduce assembly costs, which is beneficial to reducing the volume of the soft water valve. At the same time, the existence of the support structure 410 can also improve the overall strength and stability of the soft water valve to ensure its normal operation and use. In addition, by providing a fixed disk between the moving disk 300 and the support structure 410, the moving disk 300 cooperates with the fixed disk to prevent the support structure 410 from being worn, thereby improving the sealing and stability under different water path states.

[0081] Specifically, refer to Figure 5 , Figure 6 and Figure 8 In the embodiment of the utility model, the support structure 410 is evenly provided with a plurality of regions along its circumferential direction, and the plurality of cavities include a water inlet chamber 411, a water outlet chamber 412, a salt absorption chamber 413, a backwash chamber 414, a bypass chamber 415 and a diversion chamber 416, and a salt absorption chamber 413 and a backwash chamber 414 are provided in one of the regions. With the above structure, the salt absorption chamber 413 and the backwash chamber 414 are arranged in the same region, and the number of other cavities is reduced, so that the structure is more compact, which is conducive to making the support structure 410 smaller in radial dimension, and then is conducive to reducing the volume of the valve body 200, and then reducing the volume of the valve body 200, thereby reducing the overall volume of the soft water valve.

[0082] Specifically, refer to Figure 5 and Figure 6 In the embodiment of the utility model, the salt absorption chamber 413 is arranged close to the center line H of the support structure 410, and the backwash chamber 414 is arranged away from the center line H of the support structure 410. It can be understood that the salt absorption chamber 413 is located at the inner position of the support structure 410, and the backwash chamber 414 is located at the outer position of the support structure 410. Through the above arrangement, according to the flow demand, the salt absorption flow rate is smaller than the backwash flow rate, which is beneficial to manufacturing and processing, and convenient for the operation of the soft water valve.

[0083] Specifically, refer to Figure 5 and Figure 6 In the embodiment of the utility model, the opening area of ​​the salt absorption chamber 413 is smaller than the opening area of ​​the backwash chamber 414. Through the above arrangement, the requirements of both the salt absorption flow rate and the backwash flow rate are adapted, and the structure is more reasonable.

[0084] It is understandable that, referring to Figure 5 and Figure 6 In the embodiment of the utility model, the support structure 410 and the valve body 200 are integrally injection molded, and the whole formed by design and processing during the manufacturing process can provide higher structural strength and stability, reduce the connection points between parts, and thus reduce the risk of looseness or wear. Of course, the above-mentioned support structure 410 can also be a split structure with the valve body 200, and the support structure 410 and the valve body 200 can be fixedly connected by means of clamping, bolting, welding, etc.

[0085] Specifically, refer to Figure 5 and Figure 6 In the embodiment of the utility model, the support structure 410 is a support column protruding from the valve cavity 210. Through the above arrangement, the fixed plate is prevented from directly contacting the bottom wall of the valve cavity 210, and the structural strength of the support structure 410 is further improved, and it is convenient to assemble the fixed plate in the valve cavity 210, or to detach the fixed plate from the valve cavity 210, and the operation is more convenient.

[0086] It is understandable that, referring to Figure 5 and Figure 6 In the embodiment of the utility model, the cross section of the support column is circular, and multiple regions are distributed in a fan shape. The circular cross section can provide a more uniform support force, increase the strength and rigidity of the support column, and at the same time, the geometric shape of the circular cross section can avoid excessive local pressure and reduce the risk of deformation and damage to the support column; in addition, the fan-shaped distribution of the regions can make the arrangement of multiple cavities more reasonable, so that the dynamic disk 300 can achieve the relevant waterway state by rotating one circle relative to the support structure 410, the structure is more compact, the operation is more convenient, and it is conducive to reducing the volume of the soft water valve. It should be noted that the center line H of the above-mentioned support structure 410 coincides with its center.

[0087] Specifically, refer to Figure 5 and Figure 6 In the embodiment of the utility model, the central angles of the salt absorption chamber 413 and the backwash chamber 414 are equal, which further makes the support structure 410 more compact and helps to reduce the volume of the soft water valve.

[0088] Specifically, refer to Figure 5 and Figure 6In the embodiment of the utility model, the remaining areas are respectively provided with a water inlet chamber 411, a water outlet chamber 412, a bypass chamber 415 and a diversion chamber 416; a part of the structure of the water inlet chamber 411 is located in one area, and another part of the structure of the water inlet chamber 411 is located in another adjacent area, a part of the structure of the diversion chamber 416 is located at the center of the supporting structure 410, and another part of the structure of the diversion chamber 416 is located in one of the areas; wherein the diversion chamber 416 and the water inlet chamber 411 are respectively located in two different areas. The above design can provide a larger water inlet flow rate, realize water flow diversion, improve water inlet efficiency and optimize space utilization.

[0089] It should be noted that, refer to Figure 5 and Figure 6 In the embodiment of the utility model, the diversion chamber 416 and the salt absorption chamber 413 are both located away from the peripheral wall of the supporting column, and the water inlet chamber 411, the water outlet chamber 412, the backwash chamber 414 and the bypass chamber 415 are all located close to the peripheral wall of the supporting column.

[0090] It is understandable that, referring to Figure 5 and Figure 6 In this embodiment, the bypass chamber 415 and the water outlet channel 230 are arranged adjacent to each other, which can shorten the path of water from the bypass chamber 415 to the water outlet channel 230, and further make the valve body 200 narrower in width, so that the volume of the entire soft water valve is smaller.

[0091] It is understandable that, referring to Figure 5 and Figure 6In the embodiment of the utility model, a first process cavity 417 and a second process cavity 418 are provided on the support column, and the first process cavity 417 and the second process cavity 418 both extend in the thickness direction of the support column, and the first process cavity 417 and a part of the structure of the water inlet cavity 411 are located in the same area, and the first process cavity 417 is located between the bypass cavity 415 and the water inlet cavity 411, and the second process cavity 418 and a part of the structure of the diversion cavity 416 are located in the same area, and the part of the support structure 410 outside the center of the support structure 410 is divided into six equal parts along the circumferential direction, a part of the diversion cavity 416 is a center groove, and another part of the diversion cavity 416 is a fan-shaped groove, and the center groove Located at the center of the support structure 410, a part of the water inlet chamber 411 occupies one equal part, another part of the water inlet chamber 411 and the first process chamber 417 occupies one equal part, the backwash chamber 414 and the salt absorption chamber 413 occupies one equal part, the bypass chamber 415 occupies one equal part, the fan-shaped groove and the second process chamber 418 occupies one equal part, and the water outlet chamber 412 occupies one equal part. Through the above structure, by dividing the support column equally, the load of the support column can be balanced, which is conducive to ensuring that each part is subjected to the same pressure, reducing the load of a single part, thereby reducing the possibility of deformation and stress concentration, improving the stability and safety of the structure, and facilitating the relatively uniform wall thickness of the support column.

[0092] Specifically, in this embodiment, the central angle of the bypass chamber 415, the central angle of the water outlet chamber 412, the central angle of the salt absorption chamber 413, the central angle of the backwash chamber 414, the central angle of the first process chamber 417, the central angle of the second process chamber 418, the central angle of the fan-shaped groove of the diversion chamber 416 and the central angle of a part of the water inlet chamber 411 are all equal, which is further beneficial to the relatively uniform wall thickness of the support column, facilitates manufacturing and processing, and facilitates demolding.

[0093] Specifically, refer to Figure 1 In the embodiment of the utility model, the fixed plate body 100 includes an annular body 121, a central rib 122, a plurality of first ribs 123 and a plurality of second ribs 124. The central rib 122 is located at the center of the annular body 121. The plurality of first ribs 123 are spaced and evenly arranged around the central rib 122. One end of the first rib 123 is connected to the central rib 122, and the other end is connected to the peripheral wall of the annular body 121. At least two adjacent first ribs 123 are connected by the second rib 124, which helps to realize the water path switching of the soft water valve and also helps to enhance the stability and durability of the fixed plate. By connecting the first rib 123 and the second rib 124 to the central rib 122, a solid support structure 410 can be formed, thereby enhancing the overall strength and stability of the fixed plate.

[0094] Specifically, refer to Figure 1In the embodiment of the utility model, there are multiple holes, and the multiple holes are arranged around the center line M of the fixed plate body 100. Through the hole design, at least part of the holes are around the center line M of the fixed plate body 100, which can improve the structural strength of the fixed plate body 100, change the stress distribution of the material, thereby increasing the compression resistance and rigidity of the entire structure, and facilitating manufacturing and processing. Of course, in some embodiments, the arrangement of the holes can also be that at least part of the holes are arranged around the center line M of the fixed plate body 100.

[0095] It should be noted that regarding the center line M of the fixed plate body 100 , it can be understood that in this embodiment, the outer contour of the fixed plate body 100 is circular, and the center line M of the fixed plate body 100 coincides with the center of the circular fixed plate body 100 .

[0096] Specifically, refer to Figure 1 In this embodiment, two adjacent first ribs 123 and the central rib 122 cooperate to form a portion of holes, and adjacent first ribs 123, second ribs 124 and central rib 122 cooperate to form another portion of holes. The structure is simple, the layout is reasonable, and it is easy to manufacture and process.

[0097] It is understandable that, referring to Figure 1 In an embodiment of the utility model, the plurality of hole positions include a fixed water inlet hole 131, a fixed water outlet hole 132, a fixed salt absorption hole 133, a fixed backwash hole 134 and a fixed bypass hole 135; a first through hole is provided on the central rib 122, and a second through hole is formed between part of the adjacent first ribs 123 and part of the central rib 122, and the first through hole and the second through hole are connected to form a fixed diversion hole 136; wherein the fixed diversion hole 136 and the fixed salt absorption hole 133 are both located at a peripheral wall position away from the annular body 121, and the fixed water inlet hole 131, the fixed water outlet hole 132, the fixed backwash hole 134 and the fixed bypass hole 135 are all located at a peripheral wall position close to the annular body 121. Through the above structure, it is easy to adapt to the support structure 410, and better water path switching can be achieved. The design helps to achieve the functions of salt absorption, diversion, inlet and outlet, and bypass of the water flow inside the fixed plate through holes of different positions and types, which can improve the efficiency and performance of the soft water valve and meet different water treatment needs.

[0098] Specifically, in this embodiment, the fixed salt absorption hole 133 and the fixed backwash hole 134 are located between two adjacent first ribs 123, which reduces the number of other hole positions, makes the structure more compact, and is conducive to a smaller radial size of the fixed plate.

[0099] Specifically, in this embodiment, the opening area of ​​the fixed salt absorption hole 133 is smaller than the opening area of ​​the fixed backwash hole 134. Through the above arrangement, the requirements of both the salt absorption flow rate and the backwash flow rate are adapted, and the structure is relatively reasonable.

[0100] It should be noted that in the embodiment of the utility model, the salt absorption chamber 413 is used to process the salt water-containing part in the salt absorption state. Since the salt concentration in the salt water is high, the opening areas of the salt absorption chamber 413 and the corresponding fixed salt absorption hole 133 are usually small, so as to more fully carry out the salt absorption process and improve the processing efficiency of the water softener; the backwash chamber 414 and the fixed backwash hole 134 are used to clean the water softener. Its main function is to flush the softening resin component 600 with water flow, discharge impurities and pollutants therein, and maintain the cleanliness and high efficiency of the water softener. Since the backwash process requires a large water flow and pressure, its opening area is usually large, so as to discharge pollutants and impurities more quickly. Therefore, by setting the opening areas of the salt absorption chamber 413 (fixed salt absorption hole 133) and the backwash chamber 414 (fixed backwash hole 134) to be different in size, the water softener can achieve a more efficient water treatment and cleaning process, and improve the performance and service life of the water softener.

[0101] Specifically, refer to Figure 1 In the embodiment of the utility model, two partially adjacent first ribs 123, one of the second ribs 124 and the central rib 122 cooperate to form a first process hole 137, and the first process hole 137 and a part of the structure of the fixed water inlet hole 131 are located between the two adjacent first ribs 123; the other two partially adjacent first ribs 123, the other second rib 124 and the peripheral wall of the annular body 121 cooperate to form a second process hole 138, and the first process hole 137 and the second through hole are located between the two adjacent first ribs 123, which makes full use of the fixed plate area, can make the fixed plate structure more compact, save materials and reduce weight, and improve the structural strength and stability of the fixed plate.

The material of the fixed plate is a ceramic component, which has excellent corrosion resistance and can be used stably for a long time in various acid and alkali environments, can effectively resist corrosion and extend the service life. Secondly, since the surface of the ceramic material is smooth and not easy to adhere to substances, the fixed plate is relatively not easy to be contaminated during the operation process, which can reduce the cleaning frequency of the fixed plate, reduce maintenance costs, and ensure the continuous and efficient operation of the water softener. In addition, the ceramic material has high hardness and strength, can withstand greater pressure and impact, so that the fixed plate made of ceramic components can work stably in the soft water valve and is not easy to deform or break. Of course, in some embodiments, the fixed plate can also be made of other materials, such as plastic components.

Secondly, since the surface of the ceramic material is smooth and not easy to adhere to substances, the fixed disc is relatively not easy to be contaminated during the operation process, which can reduce the cleaning frequency of the moving disc 300, reduce maintenance costs, and ensure the continuous and efficient operation of the water softener. In addition, the ceramic material has high hardness and strength, and can withstand greater pressure and impact, so that the moving disc 300 made of ceramic can work stably in the soft water valve and is not easy to deform or break.

The driven gear 930 meshes with the driving gear 920 for transmission, so that the input energy of the driving motor 910 can be effectively converted into the motion energy of the transmission shaft 940, thereby driving the moving plate 300 to rotate; the meshing transmission between the driving gear 920 and the driven gear 930 can provide a stable transmission ratio and transmission efficiency, thereby ensuring the stability and reliability of the transmission process.

A plurality of sensing positions are provided on the control board 960, and a sensing element that senses and cooperates with the sensing position is provided on the driven gear 930. When the driven gear 930 rotates relative to the control board 960, the sensing position and the sensing element sense and cooperate, and then the water channel state is switched.

One side of the salt absorption and drainage device 800 is connected to the water channel component 700, and the other side of the salt absorption and drainage device 800 is connected to the softening valve.

[0108] Through the above design, the water path component 700 on the resin component 600 can allow water to flow through the resin component 600 during the softening process to remove the hardness ions in the water, and one side of the salt absorption and sewage discharge device 800 is connected to the water path component 700, and its function is to perform brine flushing and sewage discharge after the resin component 600 is saturated to restore the softening ability of the resin component 600. The other side of the salt absorption and sewage discharge device 800 is connected to the soft water valve, and the soft water valve is responsible for controlling the inlet and outlet of liquids such as softened water and brine, thereby realizing the normal operation of the water softener. The above design can effectively soften water quality, reduce the hardness components in water, and improve water quality.

[0111] It is understandable that, referring to Figure 3 and Figure 4In the embodiment of the utility model, the moving disc 300 is provided with a moving diverter groove 310, a first opening 320, a second opening 330 and a third opening 340, and the moving disc 300 is provided with an annular groove 350 and a plurality of water inlet grooves 360, the annular groove 350 is arranged around the center of the moving disc 300, and the plurality of water inlet grooves 360 are arranged at intervals and around the annular groove 350, the water inlet groove 360 ​​is connected with the annular groove 350, and the first opening 320, the second opening 330 and the third opening 340 are all connected with the annular groove 350. Through the above structure, when the moving disc 300 rotates relative to the supporting structure 410, the moving diverter groove 310, the first opening 320, the second opening 330 and the third opening 340 correspond to different areas on the supporting structure 410, so that the water softener has a service state, a salt absorption state, a bypass state, a backwash state and a water replenishment state, the structure is reasonable, and the water inlet effect is good.

[0112] Specifically, refer to Figure 3 and Figure 4 In this embodiment, the outer wall of the support structure 410 and the inner wall of the valve cavity 210 of the valve body 200 have a spacing to form a water inlet gap, and the gap is arranged around the support structure 410, the water inlet gap is connected with the water inlet cavity 411 of the support structure 410, and the water inlet gap is connected with the water inlet groove 360 ​​of the moving disk 300. The raw water reaches the water inlet gap through the water inlet channel 220, reaches the annular groove 350 through the multiple water inlet grooves 360 of the moving disk 300, and enters the water inlet cavity 411 through the annular groove 350, which can not only disperse the water inlet pressure, but also the moving disk 300 and the fixed disk are pressed tightly by water pressure.

[0113] Reference Figure 3 and Figure 4 In the embodiment of the utility model, the moving disk 300 is further provided with a plurality of blind holes. The plurality of blind holes, the first opening 320, the second opening 330 and the third opening 340 are arranged around the center line N of the moving disk 300 to improve the structural strength of the moving disk 300. The layout is reasonable and the manufacturing is convenient, which is beneficial to reducing the weight and material of the moving disk 300.

[0114] It should be noted that, regarding the center line N of the moving disk 300 , it can be understood that, in this embodiment, the outer contour of the moving disk 300 is circular, and the center line N of the moving disk 300 coincides with the center of the circular moving disk 300 .

[0115] It is understandable that, referring to Figure 5 and Figure 6In this embodiment, a blocking portion 419 is provided on the support structure 410, and the blocking portion 419 is located between the bypass chamber 415 and the water inlet chamber 411. The first process chamber 417 is provided on the blocking portion 419. The blocking portion 419 can be used to isolate the chamber positions and prevent water from being transmitted between different chamber positions, thereby avoiding water leakage when the bypass chamber 415 is not required to discharge water. For example, when softening water in the service state, the blocking portion 419 is provided, which is conducive to extending the distance between the bypass chamber 415 and the water inlet chamber 411. Since the blocking portion 419, the fixed plate and the moving plate 300 are abutted and matched in sequence, the raw water cannot directly pass through the water inlet gap, the water inlet chamber 411 and the moving diverter groove 310 to enter the bypass chamber 415, thereby ensuring the normal operation of the water softener.

[0116] Of course, in some embodiments, two adjacent cavities of the other parts may also be provided with a blocking portion 419 .

[0118] It is understandable that, referring to Figures 11 to 17 In this embodiment, the salt absorption and sewage discharge device 800 includes an ejector assembly 810, a check ball assembly 820 and a sewage discharge assembly 830.

[0119] The working process of the water softener of the utility model embodiment is described below:

[0120] When the water softener is in service, refer to Fig.11The first opening 320 and the fixed water outlet hole 132 are correspondingly connected to the water outlet cavity 412, the second opening 330, the second process hole 138 and the second process cavity 418 are correspondingly connected, the third opening 340 is correspondingly connected to a part of the structure of the water inlet cavity 411, and the other part of the structure of the water inlet cavity 411 corresponds to a part of the blind hole of the movable disk 300, wherein the remaining cavity positions and hole positions are closed, the blocking part 419, the fixed disk and the movable disk 300 are closely matched in sequence, so that the raw water passes through the water inlet channel 220 It reaches the water inlet gap and the water inlet groove 360, reaches the first port 320 through the multiple water inlet grooves 360 of the moving disk 300, reaches the tank inlet channel 240 through the fixed water outlet hole 132 and the water outlet cavity 412, and then reaches the lower part of the resin tank in the space where the resin body 630 is located outside the central tube 620 through the water channel component 700, the upper part of the resin tank and the resin body 630, and after softening, reaches the tank outlet channel 250 through the central tube 620, and reaches the water outlet channel 230 through the check valve 280.

[0121] When the water softener is in the state of absorbing salt, refer to Fig.12 , a part of the structure of the first opening 320 is correspondingly connected to the fan-shaped groove of the fixed diverter hole 136 and the diverter cavity 416, another part of the structure of the first opening 320 is correspondingly connected to the second process hole 138 and the second process cavity 418, the second opening 330 and the third opening 340 are correspondingly connected to the corresponding fixed water inlet hole 131 and the water inlet cavity 411, a part of the structure of the dynamic diverter groove 310 is correspondingly connected to the fixed salt absorption hole 133 and the salt absorption cavity 413, another part of the structure of the dynamic diverter groove 310 is correspondingly connected to the fixed bypass hole 135 and the bypass cavity 415, the raw water enters the valve cavity 210 of the valve body 200 through the water inlet channel 220, and fills the water inlet cavity 411 and the diverter cavity 416 through the water inlet gap and the water inlet groove 360. When the branch After the diversion chamber 416 of the support structure 410 is filled with raw water, the raw water is divided into two water paths through the dynamic diversion groove 310, one of which reaches the salt absorption chamber 413, and the other reaches the bypass chamber 415. The ejector assembly 810 generates negative pressure to absorb the salt water and mix the salt water and the raw water into a mixed salt solution through the ejector assembly 810. At this time, the check ball assembly 820 is opened, and the salt water reaches the central pipe 620 through the ejector assembly 810 and the check ball assembly 820, and regenerates through the central pipe 620 and the lower part of the resin tank outside the central pipe 620. Finally, the waste water is discharged through the upper part of the resin tank and the sewage discharge assembly 830, and the raw water in the other bypass chamber 415 is discharged through the water outlet channel 230 to realize water supply during regeneration.

[0122] When the water softener is in bypass mode, refer to Fig.13The first opening 320 and the second opening 330 are connected to the fixed water inlet hole 131 and the water inlet chamber 411 respectively, the third opening 340 is connected to the fixed bypass hole 135 and the bypass chamber 415 respectively, and the other cavity positions and hole positions are closed. The raw water enters the valve chamber 210 of the valve body 200, fills the water inlet chamber 411 and the water inlet gap, and reaches the bypass chamber 415 through multiple water inlet grooves 360 and the third opening 340, and is transported to the water outlet channel 230 through the bypass chamber 415 to realize water supply.

[0123] When the water softener is in backwash state, refer to Fig.14 The first opening 320 is connected to the fixed water inlet hole 131 and the water inlet chamber 411, the second opening 330 is connected to the bypass chamber 415, the third opening 340 is connected to the fixed backwash hole 134 and the backwash chamber 414, and the other chambers and holes are closed. The raw water enters the water inlet channel 220 and enters the valve chamber 210 of the valve body 200. It is divided into two raw water paths through the water inlet gap and multiple water inlet grooves 360. One path of raw water enters the backwash chamber 414, enters the central tube 620 of the resin assembly 600 through the backwash channel 270, and contacts the bottom of the resin body 630 through the lower part of the resin tank outside the central tube 620 for backwashing. The other path of raw water reaches the bypass chamber 415 and flows out through the water outlet channel 230 to realize backwash water supply.

[0124] When the water softener is in the water replenishment state, refer to Fig.15 , a part of the structure of the first port 320 and the salt absorption hole are correspondingly connected with the salt absorption chamber 413, the first port 320 and another part of the structure are correspondingly connected with the backwash chamber 414, the second port 330 is correspondingly connected with the water outlet chamber 412, and the third port 340 is correspondingly connected with the second process chamber 418. The raw water enters the water inlet gap in the valve chamber 210 of the valve body 200 through the water inlet channel 220, reaches the first port 320 and the salt absorption chamber 413 through the water inlet groove 360 ​​of the moving disk 300, and reaches the salt tank A through the ejector assembly 810 for water replenishment; the raw water reaching the water outlet chamber 412 can reach the upper part of the resin tank through the tank inlet channel 240, and after being softened by the resin body 630, it reaches the central pipe 620 through the lower part of the resin tank, and reaches the water outlet channel 230 through the tank outlet channel 250 and the check valve 280, so as to realize uninterrupted water supply, and the other cavity positions and hole positions are all closed. It should be noted that, in the water replenishment state, the check ball assembly 820 has a large water pressure on its upper part, so the ball of the check ball assembly 820 is in a position to close the check ball assembly 820. Therefore, the water passing through the ejector assembly 810 will not reach the central tube 620 of the resin assembly 600, and the water passing through the salt absorption chamber 413 can only reach the salt box A.

[0125] When the water softener is in slow wash mode, refer to Fig.16A portion of the structure of the first opening 320 is connected to the fan-shaped groove of the fixed diverter hole 136 and the diverter cavity 416, another portion of the structure of the first opening 320 is connected to the second process hole 138 and the second process cavity 418, the second opening 330 and the third opening 340 are connected to the corresponding fixed water inlet hole 131 and the water inlet cavity 411, a portion of the structure of the dynamic diverter groove 310 is connected to the fixed salt absorption hole 133 and the salt absorption cavity 413, another portion of the structure of the dynamic diverter groove 310 is connected to the fixed bypass hole 135 and the bypass cavity 415, and the remaining cavity positions and hole positions are closed. The raw water enters the valve cavity 210 of the valve body 200 through the water inlet channel 220, and fills the water inlet cavity 411 and the diverter cavity 416 through the water inlet gap and the water inlet groove 360. When the diverter cavity 416 of the support structure 410 is filled with raw water, the raw water is divided into two water paths through the dynamic diverter groove 310. Since the ejector assembly 810 has absorbed all the salt water at this time and is disconnected from the salt tank A, one of the raw water paths reaches the salt absorption cavity 413, and the check ball assembly 820 is opened. The raw water reaches the central pipe 620 through the ejector assembly 810 and the check ball assembly 820, and contacts with the resin body 630 through the central pipe 620 and the lower part of the resin tank outside the central pipe 620 for slow washing. Finally, the waste water is discharged through the upper part of the resin tank and the sewage discharge assembly 830, and the raw water in the bypass cavity 415 is discharged through the water outlet channel 230 to achieve uninterrupted water supply.

[0126] When the water softener is in a mixed water state, refer to Fig.17 During the water mixing process, the first opening 320 of the moving disk 300 and the fixed water outlet hole 132 and the water outlet cavity 412 of the fixed disk are staggered at a preset angle to mix the water, and a part of the fixed diversion hole 136 and the diversion cavity 416 is connected to the first opening 320, a part of the first opening 320 is correspondingly connected to a part of the fixed water outlet hole 132 and the water outlet cavity 412 of the fixed disk, another part of the first opening 320 is correspondingly connected to another part of the second process hole 138 and the second process cavity 418 of the fixed disk, and a part of the second opening 330 is correspondingly connected to another part of the second process hole 138 and the second process cavity 418 of the fixed disk. The other part of the structure of the second opening 330 is connected with the fixed water inlet hole 131 and the part of the structure of the water inlet chamber 411. The third opening 340 is connected with the fixed water inlet hole 131 and the part of the structure of the water inlet chamber 411. After a part of the raw water reaches the valve chamber 210 of the valve body 200 through the water inlet channel 220, it reaches the water outlet chamber 412 through the water inlet gap and the water inlet groove 360, and reaches the area where the resin body 630 of the resin assembly 600 is located through the water outlet chamber 412 and the tank inlet channel 240, and reaches the check valve 280 after being softened. The other part of the raw water reaches the backwash chamber 414, and reaches the water outlet through the backwash channel 270, and the two parts of water are mixed.

[0127] It can be understood that in the embodiment of the utility model, in the slow washing state, the channel between the salt box A and the ejector assembly 810 is closed, so that the resin body 630 is slowly flushed with the original mixed salt solution and the newly introduced raw water; in the mixed water state, the hardness adjustment of the soft water is achieved.

[0128] It should be noted that in the embodiment of the utility model, since the supporting structure 410 is divided into six equal parts, when the water softener is in a water mixing state, during the water mixing process, the first opening 320 of the movable disk 300 and the fixed water outlet hole 132 and the water outlet cavity 412 of the fixed disk are staggered at a preset angle for water mixing, wherein the angle value range of the preset angle is greater than 0 degrees and less than 60 degrees. For example, the movable disk 300 can be rotated to 35 degrees or to 30 degrees to achieve a water mixing state.
