[0061] Combine the following Figure 1-Figure 18 The valve seat of the water softening valve, the water softening valve and the water softener according to the embodiment of the utility model are described.

[0062] Reference Fig.11 According to a water softener of an embodiment of the utility model, the water softener includes a water softening valve, a resin component 710 and a salt absorption and drainage device 720. The resin component 710 is provided with a water channel component 711 for water circulation. One side of the salt absorption and drainage device 720 is connected to the water channel component 711, and the other side of the salt absorption and drainage device 720 is connected to the water softening valve.

[0063] Through the above design, the water path component 711 on the resin component 710 can allow water to flow through the resin component 710 during the softening process to remove the hardness ions in the water, and one side of the salt absorption and sewage discharge device 720 is connected to the water path component 711, and its function is to perform brine flushing and sewage discharge after the resin component 710 is saturated to restore the softening ability of the resin component 710. The other side of the salt absorption and sewage discharge device 720 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, so as to achieve the normal operation of the water softener. The above design can effectively soften the water quality, reduce the hardness components in the water, and improve the quality of the water.

[0064] It should be noted that in some embodiments of the present invention, the water softener also includes a salt tank A; through the operation of the soft water valve, the water softener has a service state, a salt absorption state, a bypass state, a backwash state, a water replenishment state, a slow wash state and a mixed water state.

[0065] It can be understood that, according to the soft water valve of the embodiment of the utility model, the soft water valve includes a valve seat, a fixed plate 300, a movable plate 400 and a driving mechanism.

[0066] Reference Figures 1 to 3According to the valve seat of the soft water valve of the embodiment of the utility model, the valve seat includes a seat body 100 and a supporting structure 200, the seat body 100 is provided with a chamber 110; the supporting structure 200 is connected to the seat body 100, and the supporting structure 200 is arranged in the chamber 110; wherein, the supporting structure 200 is provided with a blocking portion 210, a water inlet chamber 220 and a bypass chamber 260, and the blocking portion 210 is located between the water inlet chamber 220 and the bypass chamber 260.

[0067] According to the valve seat of the soft water valve in the embodiment of the utility model, by providing a blocking portion 210, when the soft water valve of the water softener is in the service state of making soft water and the resin of the water softener is regenerated, it can prevent water from easily leaking between different water channels of the valve seat of the soft water valve, ensure that the water channel switching only occurs between predetermined cavity positions, thereby avoiding water leaking, increasing the reliability and stability of the valve seat, ensuring the accuracy of water channel switching, and facilitating the normal use of the soft water valve.

[0068] It should be noted that, in this embodiment, the bypass chamber 260 can be understood as: water flows directly through the soft water valve without being softened, and is directly supplied to the equipment or area requiring water through the bypass chamber 260 .

[0069] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the blocking portion 210 is a blocking wall arranged along the thickness direction of the support structure 200. With the above structure, the blocking wall, as a part of the support structure 200, increases the strength and rigidity of the structure in the thickness direction. The design of the blocking portion 210 can make the support structure 200 easier to process and manufacture without the need for additional components or complicated installation processes.

[0070] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the radial cross-section of the blocking portion 210 is fan-shaped. The fan-shaped design can provide better structural support, increase the rigidity and strength of the blocking portion 210, and is conducive to regulating the speed and flow direction of the liquid, optimizing the fluid dynamics performance, and reducing energy loss.

[0071] It is understandable that, referring to Figure 5 , Figure 6 , Fig. 9 and Fig.10In this practical embodiment, the moving disc 400 is disposed in the chamber 110, and the moving disc 400 is rotatable relative to the supporting structure 200 to switch the waterway state; wherein the blocking portion 210 cooperates with a partial structure of the moving disc 400 to limit the connection between the water inlet chamber 220 and the bypass chamber 260 in at least one waterway state. Through the cooperation between the moving disc 400 and the valve seat, it can be adjusted and controlled as needed, and by switching the waterway, different functions and uses can be achieved 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. Specifically, the moving disc 400 is rotatable relative to the supporting structure 200, so that the valve seat and the moving disc 400 at least define a service waterway, a salt water absorption waterway, a bypass waterway, a backwash waterway, and a water replenishment waterway.

[0072] Specifically, refer to Figure 4 , Fig. 9 and Fig.10 In the embodiment of the utility model, the fixed plate 300 is arranged in the chamber 110, the fixed plate 300 is fixed relative to the supporting structure 200, the radial shape of the fixed plate 300 is adapted to the supporting structure 200 of the supporting column, the moving plate 400 cooperates with the supporting structure 200 and the fixed plate 300, the moving plate 400 is rotatable relative to the supporting structure 200, and can be adjusted and controlled as needed. By switching the water path, different functions and uses can be achieved 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; secondly, through the cooperation between the moving plate 400 and the fixed plate 300, the support structure 200 can be prevented from being worn, and the sealing and stability under different water path conditions can be improved.

[0073] It can be understood that in the embodiment of the utility model, the moving disk 400 and the fixed disk 300 are both ceramic parts. The use of ceramic parts has excellent corrosion resistance, 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, it is relatively not easy to be contaminated during the working process, which can reduce the cleaning frequency, 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 ceramic parts can work stably in the soft water valve and are not easy to deform or break. Of course, in some embodiments, the moving disk 400 and the fixed disk 300 can also be made of other materials, such as plastic parts.

[0074] It is understandable that, referring to Figure 7 , Fig. 9 and Fig.10In the embodiment of the utility model, a sealing structure 500 is provided between the fixed plate 300 and the supporting structure 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 supporting structure 200, thereby improving the sealing performance of the two.

[0075] Specifically, the sealing structure 500 is a sealing gasket, which can provide a certain friction force between the supporting structure 200 and the fixed plate 300, which is helpful to prevent the fixed plate 300 from rotating relative to the supporting structure 200 and improve the working stability.

[0076] It should be noted that, refer to Figure 1 , Figure 2 , Figures 8 to 10 In this embodiment, a water inlet channel 120, a water outlet channel 130, a tank inlet channel 160, a tank outlet channel 170, a salt absorption channel 140 and a backwash channel 150 are provided on the seat body 100, and a water outlet chamber 230, a salt absorption chamber 240 and a diversion chamber 270 are also provided on the supporting column. The water inlet chamber 220 is connected to the water inlet channel 120, the salt absorption chamber 240 is connected to the salt absorption channel 140, the backwash chamber 250 is connected to the backwash channel 150, and the bypass chamber 260 and the tank outlet channel 170 are both connected to the water outlet channel 130.

[0077] Specifically, in this embodiment, refer to Figure 4 The fixed plate 300 is provided with a fixed salt absorption 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 7The sealing structure 500 has corresponding sealed water inlet holes 530, sealed water outlet holes 540, sealed salt absorption holes 510, sealed backwash holes 520, sealed bypass holes 550, sealed diverter holes 560, sealed first process holes 570 and sealed second process holes 580. The water inlet chamber 220, the fixed water inlet hole 330 and the sealed water inlet hole 530 correspond to each other, the water outlet chamber 230, the fixed water outlet hole 340 and the sealed water outlet hole 540 correspond to each other, the salt absorption chamber 240, the fixed salt absorption hole 310 and the sealed salt absorption hole 510 correspond to each other, the backwash chamber 250, the fixed backwash hole 320 and the sealed backwash hole 520 correspond to each other, the bypass chamber 260, the fixed bypass hole 350 and the sealed bypass hole 550 correspond to each other, the diverter chamber 270, the fixed diverter hole 360 ​​and the sealed diverter hole 560 correspond to each other, and the first The process cavity 280, the first process hole 370 and the sealing process hole 570 correspond to each other, and the second process cavity 290, the second process hole 380 and the sealing process hole 580 correspond to each other, wherein sealing ribs are provided between the holes on the sealing structure 500 to limit the connection between adjacent holes; the moving disk 400 is provided with a moving diversion groove 410, a first opening 420, a second opening 430 and a third opening 440, and the moving disk 400 is provided with an annular groove 450 and a plurality of water inlet grooves 460, the annular groove 450 is arranged around the center of the moving disk 400, and the plurality of water inlet grooves 460 are spaced apart and arranged around the annular groove 450, the water inlet groove 460 is connected with the annular groove 450, and the first opening 420, the second opening 430 and the third opening 440 are all connected to the annular groove 450. Through the above structure, when the moving disk 400 rotates relative to the supporting structure 200, the moving diverter groove 410, the first port 420, the second port 430 and the third port 440 correspond to the cavities in different areas of the supporting structure 200, so that the water softener can have service state, salt absorption state, bypass state, backwash state, water replenishment state, slow wash state and mixed water state. The structure is reasonable and the water inlet effect is good.

[0078] It should be noted that, in the embodiment of the utility model, the salt absorption channel 140, the backwash channel 150 and the tank outlet channel 170 can all be connected to the central tube 713, and the water outlet chamber 230 is connected to the space where the resin body 714 is located outside the central tube 713 through the tank inlet channel 160; a check valve 180 and a flow meter 190 are provided on the seat body 100, and the water outlet channel 130 and the tank outlet channel 170 are connected through the check valve 180, so that the tank outlet channel 170 is unidirectionally connected to the water outlet channel 130, and the liquid is prevented from flowing to the tank outlet channel 170 through the bypass chamber 260; the orthographic projections of the salt absorption channel 140 and the backwash chamber 250 overlap, so as to realize the control of multiple waterways, make the support column design more reasonable, and help to reduce the volume of the soft water valve; one end of the ejector assembly 721 is connected to the salt absorption channel 140, and one end of the check ball assembly 722 is connected to the other end of the ejector assembly 721.

[0079] Specifically, in this embodiment, the outer wall of the support structure 200 and the inner wall of the chamber 110 of the seat body 100 have a spacing to form a water inlet gap. The water inlet gap is arranged around the support structure 200, and the water inlet gap is connected to the water inlet cavity 220 of the support structure 200, and the water inlet gap is connected to the water inlet groove 460 of the moving plate 400. The raw water reaches the water inlet gap through the water inlet channel 120, reaches the annular groove 450 through the multiple water inlet grooves 460 of the moving plate 400, and enters the water inlet cavity 220 through the annular groove 450, which can not only disperse the water inlet pressure, but also the moving plate 400 and the fixed plate 300 are pressed by water pressure.

[0080] It is understandable that, referring to Figure 2 and Figure 3 In the embodiment of the utility model, the blocking part 210 is located between the bypass chamber 260 and the water inlet chamber 220. The above structure is adopted to avoid water leakage when the bypass chamber 260 is not needed to discharge water. For example, when softening water in the service state, the blocking part 210 is provided, which is conducive to extending the distance between the bypass chamber 260 and the water inlet chamber 220. Since the blocking part 210, the fixed plate 300 and the moving plate 400 are abutted and matched in sequence, the raw water cannot directly pass through the water inlet gap, the water inlet chamber 220 and the moving diverter groove 410 to enter the bypass chamber 260, thereby ensuring the normal operation of the water softener. During the resin regeneration, that is, the salt absorption state and the slow washing state, since the blocking part 210, the fixed plate 300 and the moving plate 400 are abutted and matched in sequence, the raw water cannot directly pass through the water inlet chamber 220 to enter the bypass chamber 260, thereby ensuring the normal operation of the water softener.

[0081] It is understandable that, referring to Figure 2 and Figure 3 In the embodiment of the utility model, the blocking part 210 is provided with a first process cavity 280, and the depth of the first process cavity 280 is set along the thickness direction of the support structure 200. This is beneficial to the uniform wall thickness of the support structure 200, facilitates mold opening, avoids shrinkage of the support structure 200, and facilitates manufacturing and processing.

[0082] Specifically, refer to Figure 2 and Figure 3 In the present embodiment, the depth of the first process chamber 280 is consistent with the thickness of the support structure 200. The consistency of the thickness of the first process chamber 280 and the support structure 200 can provide better structural stability.

[0083] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the radial cross section of the first process chamber 280 is fan-shaped. The radial cross section of the first process chamber 280 is fan-shaped, and the shapes of the first process chamber 280 and the blocking portion 210 are matched, thereby improving the structural strength and stability of the blocking portion 210, and facilitating manufacturing and processing.

[0084] Specifically, refer to Figures 1 to 3 In an embodiment of the utility model, the radial cross-section of the support structure 200 is circular. The circular cross-section can provide a more uniform supporting force, increase the strength and rigidity of the support structure 200, 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 of the support structure 200.

[0085] Specifically, refer to Figure 1 , Figure 2 and Fig. 9 In the embodiment of the utility model, the support structure 200 is integrally injection molded with the seat body 100.

The ejector assembly 721 generates negative pressure to suck in the salt water and mix the salt water and the raw water into a mixed salt solution through the ejector assembly 721. At this time, the check ball assembly 722 is opened, and the salt water reaches the central pipe 713 through the ejector assembly 721 and the check ball assembly 722, and contacts with the resin through the central pipe 713 and the lower part of the resin tank outside the central pipe 713 for regeneration. Finally, the waste water is discharged through the upper part of the resin tank and the sewage discharge assembly 723, and the raw water in the other bypass chamber 260 is discharged through the water outlet channel 130 to realize water supply during regeneration.

[0096] When the water softener is in bypass mode, refer to Fig.14 The first opening 420 and the second opening 430 are connected to the fixed water inlet hole 330 and the water inlet chamber 220 respectively, the third opening 440 is connected to the fixed bypass hole 350 and the bypass chamber 260 respectively, and the other cavity positions and hole positions are closed.

[0097] When the water softener is in backwash state, refer to Fig.15 The first opening 420 is connected to the fixed water inlet hole 330 and the water inlet chamber 220, the second opening 430 is connected to the bypass chamber 260, the third opening 440 is connected to the fixed backwash hole 320 and the backwash chamber 250, and the other chambers and holes are closed. The raw water enters the water inlet channel 120 and enters the chamber 110 of the valve seat. It is divided into two paths of raw water through the water inlet gap and multiple water inlet grooves 460. One path of raw water enters the backwash chamber 250, enters the central tube 713 of the resin assembly 710 through the backwash channel 150, and contacts the bottom of the resin body 714 through the lower part of the resin tank outside the central tube 713 for backwashing. The other path of raw water reaches the bypass chamber 260 and flows out through the water outlet channel 130 to realize backwash water supply.

[0098] When the water softener is in the water replenishment state, refer to Fig.16 , a part of the structure of the first port 420 and the salt absorption hole are correspondingly connected with the salt absorption chamber 240, the first port 420 and another part of the structure are correspondingly connected with the backwash chamber 250, the second port 430 is correspondingly connected with the water outlet chamber 230, and the third port 440 is correspondingly connected with the second process chamber 290. The raw water enters the water inlet gap in the chamber 110 of the valve seat through the water inlet channel 120, reaches the first port 420 and the salt absorption chamber 240 through the water inlet groove 460 of the moving disk 400, and reaches the salt box A through the ejector assembly 721 for water replenishment; the raw water reaching the water outlet chamber 230 can reach the upper part of the resin tank through the tank inlet channel 160, and after being softened by the resin, it reaches the central pipe 713 through the lower part of the resin tank, and reaches the water outlet channel 130 through the tank outlet channel 170 and the check valve 180, 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 722 has a large water pressure on its upper part, so the ball of the check ball assembly 722 is in the position of closing the check ball assembly 722. Therefore, the water passing through the ejector assembly 721 will not reach the central tube 713 of the resin assembly 710, and the water passing through the salt absorption chamber 240 can only reach the salt box A.

[0099] When the water softener is in slow wash mode, refer to Fig.17 A portion of the structure of the first opening 420 is connected to the fan-shaped groove of the fixed diverter hole 360 ​​and the diverter cavity 270, another portion of the structure of the first opening 420 is connected to the second process hole 380 and the second process cavity 290, the second opening 430 and the third opening 440 are connected to the corresponding fixed water inlet hole 330 and the water inlet cavity 220, a portion of the structure of the dynamic diverter groove 410 is connected to the fixed salt absorption hole 310 and the salt absorption cavity 240, another portion of the structure of the dynamic diverter groove 410 is connected to the fixed bypass hole 350 and the bypass cavity 260, and the remaining cavity positions and hole positions are closed. The raw water enters the chamber 110 of the valve seat through the water inlet channel 120, and fills the water inlet chamber 220 and the diverter chamber 270 through the water inlet gap and the water inlet groove 460. When the diverter chamber 270 of the support structure 200 is filled with raw water, the raw water is divided into two water paths through the dynamic diverter groove 410. Since the ejector assembly 721 has absorbed all the brine at this time and is disconnected from the salt tank A, one of the raw water paths reaches the salt absorption chamber 240, and the check ball assembly 722 is opened. The raw water reaches the central pipe 713 through the ejector assembly 721 and the check ball assembly 722, and contacts with the resin through the central pipe 713 and the lower part of the resin tank outside the central pipe 713 for slow washing. Finally, the waste water is discharged through the upper part of the resin tank and the sewage discharge assembly 723. The raw water in the other bypass chamber 260 is discharged through the water outlet channel 130 to achieve uninterrupted water supply.

[0100] When the water softener is in a mixed water state, refer to Fig.18During the water mixing process, the first opening 420 of the moving plate 400 and the fixed water outlet hole 340 and the water outlet cavity 230 of the fixed plate 300 are staggered at a preset angle to mix the water, and a part of the fixed diverter hole 360 ​​and the diverter cavity 270 is connected to the first opening 420, a part of the first opening 420 is correspondingly connected to a part of the fixed water outlet hole 340 and the water outlet cavity 230 of the fixed plate 300, another part of the first opening 420 is correspondingly connected to another part of the second process hole 380 and the second process cavity 290 of the fixed plate 300, and a part of the second opening 430 is correspondingly connected to another part of the second process hole 380 and the second process cavity 290 of the fixed plate 300.

After a part of the raw water reaches the chamber 110 of the valve seat through the water inlet channel 120, it reaches the water outlet chamber 230 through the water inlet gap and the water inlet groove 460, and reaches the area where the resin body 714 of the resin assembly 710 is located through the water outlet chamber 230 and the tank inlet channel 160, and reaches the check valve 180 after being softened. The other part of the raw water reaches the backwash chamber 250, reaches the water outlet through the backwash channel 150, and the two parts of water are mixed.

[0101] It should be noted that, in the slow washing state, the channel between the salt box A and the ejector assembly 721 is closed, so that the resin is slowly flushed 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; in the embodiment of the utility model, since the support structure 200 is divided into six equal parts, when the water softener is in the mixed water state, during the mixed water process, the first opening 420 of the moving disk 400 and the fixed water outlet hole 340 and the water outlet cavity 230 of the fixed disk 300 are staggered at a preset angle for mixing water, wherein the angle value range of the preset angle is greater than 0 degrees and less than 60 degrees.
