[0056] The present invention provides a soft water valve.

[0057] Reference Figures 1 to 7 In one embodiment of the present invention, the soft water valve comprises:

[0058] The valve body 1 is provided with a valve chamber 11, a water mixing channel 17, a water inlet channel 101, and a water outlet channel 105. The valve chamber 11 includes a water inlet chamber 112 communicating with the water inlet channel 101, and a water outlet chamber 116 communicating with the water outlet channel 105. The first end of the water mixing channel 17 communicates with the water inlet channel 101, and the second end communicates with the water outlet chamber 116.

[0059] The water mixing valve 81 is provided in the water mixing channel 17 .

[0060] However, the present design is not limited to this. In other embodiments, the first end of the mixed water channel 17 may also be connected to the water inlet chamber 112. It can be understood that since the water inlet chamber 112 is connected to the water inlet channel 101, the first end of the mixed water channel 17 is connected to the water inlet chamber 112, and the effect of its connection with the water inlet channel 101 is the same, and both can draw out raw water from the water inlet position of the valve body 1; of course, the first end of the mixed water channel 17 can also be connected to the water inlet chamber 112 and the water inlet channel 101 at the same time. Without loss of generality, the second end of the mixed water channel 17 can also be connected to the water outlet channel 105. It can be understood that since the water outlet channel 105 is connected to the water outlet chamber 116, the second end of the mixed water channel 17 is connected to the water outlet channel 105, and the effect of its connection with the water outlet chamber 116 is the same, and both can transport the drawn raw water to the water outlet position of the valve body 1; of course, the second end of the mixed water channel 17 can also be connected to the water outlet chamber 116 and the water outlet channel 105 at the same time.

[0061] In the technical solution of the present invention, when the water softener equipped with the softening valve is in the water production mode, when the mixing valve is opened, a portion of the raw water can flow from the water inlet channel 101 and / or the water inlet chamber 112 directly through the mixing channel into the water outlet chamber 116 and / or the water outlet channel 105, thereby mixing with the softened soft water (sodium ions will increase during the softening process), and then transported to the external water outlet pipe to reduce the phenomenon of excessive sodium ions, thereby meeting the low concentration requirements of sodium ions in certain regions (such as Europe).

[0062] Optionally, a first communication hole 91 is provided on the wall of the water inlet channel 101, and the mixed water channel 17 communicates with the water inlet channel 101 through the first communication hole 91. However, the present design is not limited thereto. In other embodiments, a communication hole for communicating with the mixed water channel 17 may also be provided on the wall of the water inlet chamber 112; and in still other implementations, communication holes for communicating with the mixed water channel 17 may also be provided on both the wall of the water inlet channel 101 and the wall of the water inlet chamber 112.

[0063] Optionally, a second communication hole 92 is provided on the wall of the water outlet chamber 116, and the mixed water channel 17 communicates with the water outlet chamber 116 through the second communication hole 92. However, the present design is not limited thereto. In other embodiments, a communication hole for communicating with the mixed water channel 17 may be provided on the wall of the water outlet channel 105. In still other implementations, communication holes for communicating with the mixed water channel 17 may be provided on both the wall of the water outlet channel 105 and the wall of the water outlet chamber 116.

[0064] In one embodiment, the mixing valve 81 includes a valve stem 811, which is positioned corresponding to the second communicating hole 92 and is used to open or close the second communicating hole 92. It will be appreciated that in this embodiment, the valve stem 811 of the mixing valve 81 is parallel to the water outlet channel 105, facilitating installation of the valve stem 811. However, if the valve stem 811 were perpendicular to the water outlet channel 105, the valve stem 811 might be affected by other channels, such as the water inlet channel 101 or the sewage channel 103, during installation, thereby limiting the space available for installation.

[0065] Optionally, in the axial direction of the valve chamber 11, the mixing channel 17 includes a first channel section 171, a second channel section 172, and a third channel section 173, which are connected in sequence. The first connecting hole 91 is connected to the first channel section 171, and the second connecting hole 92 is connected to the third channel section 173. In the radial direction of the valve chamber 11, the width of the first channel section 171 is greater than the width of the second channel section 172. It can be understood that the first connecting hole 91 is connected to the first channel section 171. Increasing the width of the first channel section 171 can facilitate the opening of the first connecting hole 91 and, if necessary, allow the first connecting hole 91 to be larger. Furthermore, in the radial direction of the valve chamber 11, the width of the third channel section 173 is greater than the width of the second channel section 172, thereby providing more space for the installation of the mixing valve 81.

[0066] In this embodiment, in the radial direction of the valve cavity 11, the width of the first flow channel section 171 and the width of the third flow channel section 173 are both greater than the width of the second flow channel section 172. However, the present design is not limited to this. In other embodiments, in the radial direction of the valve cavity 11, only the width of the first flow channel section 171 may be set to be greater than the width of the second flow channel section 172, or only the width of the third flow channel section 173 may be set to be greater than the width of the second flow channel section 172.

[0067] Optionally, the drain channel 103 of the valve body 1 is arranged corresponding to the second flow channel section 172; it can be understood that since the second flow channel section 172 is narrowest in the radial direction of the valve cavity 11, the drain channel 103 is arranged at a position corresponding to the second flow channel section 172, so that more operating space can be provided to facilitate the disassembly and assembly of the drain joint and the drain channel 103.

[0068] In one embodiment, the opening of the second communicating hole 92 away from the water outlet chamber 116 is flared, and the end of the valve stem 811 proximal to the second communicating hole 92 is gradually tapered in the direction toward the second communicating hole 92. This increases the mating area between the valve stem 811 and the second communicating hole 92, improving the reliability of the valve stem 811 in closing the second communicating hole 92. Optionally, the corresponding opening of the second communicating hole 92 is conical, and the outer peripheral surface of the closing end of the valve stem 811 is also conical, with the slopes of the two conical surfaces being consistent or approaching consistency, so that the two conical surfaces can fit face to face when closed, thereby improving the sealing performance when closed.

[0069] In one embodiment, the opening of the valve stem 811 relative to the second connecting hole 92 is adjustable. It will be appreciated that the greater the opening, the greater the proportion of raw water that can be mixed into the softener's outlet water, and the lower the sodium ion concentration of the outlet water; the smaller the opening, the smaller the proportion of raw water that can be mixed into the softener's outlet water, and the higher the sodium ion concentration of the outlet water. By making the opening of the valve stem 811 relative to the second connecting hole 92 adjustable, this embodiment enables adjustable sodium ion concentration in the softener's outlet water, thereby meeting the varying upper limits on sodium ion concentration required in different regions.

[0070] Optionally, the mixing valve 81 further includes a mounting nut 812. A mounting hole 170 is provided on the channel wall of the mixing channel 17 away from the valve chamber 11. The mounting nut 812 is threadedly connected to the mounting hole 170. The valve stem 811 is threadedly connected to the mounting nut 812, so that the opening of the valve stem 811 relative to the second connecting hole 92 is adjustable. Thus, the opening of the valve stem 811 relative to the second connecting hole 92 can be adjusted by rotating the valve stem 811. The rotational operation is convenient, and the rotational adjustment allows for infinitely variable adjustment of the opening, enabling more precise adjustment of the sodium ion concentration. Further optionally, a first spiral rib is provided on the outer circumference of the valve stem 811, and a second spiral rib is provided on the inner circumference of the mounting nut 812 corresponding to the first spiral rib, with the first spiral rib and the second spiral rib cooperating.

[0071] However, the present design is not limited thereto. In other embodiments, the opening adjustment method of the valve stem 811 relative to the second connecting hole 92 may also be step-by-step, for example, by gradually plugging and unplugging to achieve step-by-step adjustment of the opening.

[0072] To facilitate rotation of the valve stem 811, a rotating handle 813 is optionally provided at the end of the valve stem 811 away from the second connecting hole 92. Without loss of generality, the outer circumference of the rotating handle 813 may be provided with multiple flats or anti-slip grooves to increase grip friction. The end surface of the rotating handle 813 may also be provided with a slot or a cross slot to facilitate rotation of the valve stem 811 with a screwdriver, thereby adjusting the opening of the valve stem 811 relative to the second connecting hole 92. To ensure effective transmission between the rotating handle 813 and the valve stem 811, the rotating handle 813 and the valve stem 811 may optionally be connected via a spline structure.

[0073] Optionally, the valve body 1 is configured as an injection-molded part. To improve the installation stability between the mounting nut 812 and the channel wall of the water mixing channel 17, the channel wall of the water mixing channel 17 needs to be relatively thick. However, if the thickness is relatively large, the corresponding channel wall is prone to collapse and form a depression after injection molding, resulting in an increased product scrap rate. To reduce the probability of collapse and depression, further optionally, an anti-collapse cavity is provided in the channel wall of the water mixing channel 17 away from the valve cavity 11. The mounting hole 170 is provided through the anti-collapse cavity. When the valve body 1 is formed by injection molding, the anti-collapse cavity reduces the probability of collapse and depression in the corresponding channel wall, thereby improving the product yield rate.

[0074] In one embodiment, reference is made to Figures 8 to 12 , the valve body 1 is also provided with a side wall channel 102, a central channel 104, a sewage discharge channel 103 and a salt absorption and water injection channel;

[0075] The soft water valve further includes a grille assembly 2 provided in the valve chamber 11 and a piston 3 provided in the grille assembly 2. The grille assembly 2 divides the valve chamber 11 into a plurality of water passage chambers 111 in sequence along its axial direction. The plurality of water passage chambers 111 include a water inlet chamber 112, a side wall chamber 113 communicating with the side wall channel 102, a sewage discharge chamber 114 communicating with the sewage discharge channel 103, a central chamber 115 communicating with the central channel 104, a water outlet chamber 116, and a water injection and salt absorption chamber 117 communicating with the salt absorption and water injection channel. The water inlet chamber 112, the side wall chamber 113, the sewage discharge chamber 114, the central chamber 115, the water outlet chamber 116, and the water injection and salt absorption chamber 117 are sequentially arranged along the axial direction of the valve chamber 11.

[0076] The soft water valve has multiple water path modes, and the piston 3 moves along the axial direction of the valve cavity 11 to switch the soft water valve between the multiple water path modes.

[0077] Without loss of generality, the valve body is provided with a soft tank interface 161 (see Figure 19 ), the sidewall channel 102 and the central channel 104 are disposed within the soft tank interface 161. The soft tank interface 161 is configured to connect to the soft water tank 200 of the water softener. The soft water tank 200 contains a softening medium for softening raw water entering the soft water tank 200 to reduce the hardness of the water used by users. The salt absorption and injection channel is configured to connect to the salt tank 300, which contains regeneration salt for regenerating the softening medium in the soft water tank 200.

[0078] Optionally, the grid assembly 2 includes a plurality of support retaining rings 24 arranged at intervals, the outer peripheries of the plurality of support retaining rings 24 abut against the inner periphery of the valve cavity 11 , the inner peripheries of the support retaining rings 24 abut against the piston 3 , and a water passage cavity 111 is formed between two adjacent support retaining rings 24 .

[0079] This piston-type water softener has a larger flow rate and higher water softening efficiency, making it easier to achieve the design goals of small size, large flux, high water production, and high salt efficiency. Furthermore, this piston-type water softener has a long service life. The piston 3 is inserted into the inner periphery of the grille assembly 2, and the outer periphery of the piston 3 is in sealing contact with the inner periphery of the grille assembly 2, that is, the outer periphery of the piston 3 is in sealing contact with the inner periphery of the support ring 24, thereby cutting off the communication between two adjacent water passage chambers 111. The piston 3 is generally provided with multiple water passage positions. When the piston 3 moves to a certain position, at least one of the multiple support rings 24 is positioned relative to the water passage position of the piston 3, thereby forming a water passage gap between the inner periphery of the support ring 24 and the water passage position of the piston 3, thereby achieving communication between the water passage chambers 111 on both sides of the support ring 24. Thus, through the movement of the piston 3, communication is established between the different water passage chambers 111, thereby controlling the direction of water flow and forming corresponding waterways.

[0080] The water inlet chamber 112 can be connected to the water inlet channel 101, which is used to connect to the external water inlet pipe to supply raw water to the soft water valve; the side wall chamber 113 is connected to the soft water tank 200 through the side wall channel 102; the sewage chamber 114 is connected to the external sewage pipe through the sewage channel 103, so as to discharge the waste water in the water softener; the central chamber 115 is connected to the soft water tank 200 through the central channel 104; the water outlet chamber 116 is connected to the external water outlet pipe through the water outlet channel 105, and can discharge the produced soft water; the water injection and salt absorption chamber 117 is connected to the salt box 300 through the water injection and salt absorption channel 106, so as to realize water injection into the salt box 300 and pass the salt water in the salt box 300 into the soft water tank 200, so as to realize the regeneration of the soft water medium in the soft water tank 200.

[0081] The water inlet chamber 112 and the water outlet chamber 116 are both connected to the external pipeline, but are not connected to the soft water tank 200, while the side wall chamber 113 and the central chamber 115 are both connected to the soft water tank 200. Therefore, the water inlet chamber 112 and the water outlet chamber 116 can be connected to the soft water tank 200 with the help of the side wall chamber 113 and the central chamber 115. Therefore, the side wall chamber 113 is adjacent to the water inlet chamber 112, so that the water inlet chamber 112 is connected to the soft water tank 200 through the side wall chamber 113, and the two are adjacent to each other, thereby narrowing the flow path of raw water flowing into the soft water tank 200, thereby simplifying the water path in the soft water valve; the central chamber 115 is adjacent to the water outlet chamber 116, so that the water outlet chamber 116 is connected to the soft water tank 200 through the central chamber 115, and the two are adjacent to each other, thereby narrowing the flow path of softened soft water flowing out of the soft water tank 200, thereby simplifying the water path in the soft water valve.

[0082] When the softened soft water in the soft water tank 200 flows out of the soft water valve, part of the soft water can flow into the water absorption and salt injection chamber 117, thereby injecting water into the salt tank 300. Therefore, the water injection and salt absorption chamber 117 is adjacent to the side of the water outlet chamber 116 away from the central chamber 115, so that when the soft water flows through the water outlet chamber 116, part of the soft water can flow directly from the water outlet chamber 116 to the water injection and salt absorption chamber 117. Compared with the water injection and salt absorption chamber 117 and the water outlet chamber 116 being separated and connected by a special flow channel, this solution can effectively shorten the flow path of the soft water flowing into the salt tank 300, thereby further optimizing the water path of the soft water valve, and no additional special flow channel is required, which helps to reduce the volume of the soft water valve.

[0083] In one embodiment, the water inlet channel 101, the water outlet channel 105, the sewage discharge channel 103 and the salt absorption and injection channel 106 are all arranged in a horizontal direction, so as to reduce the longitudinal height of the valve body 1 on the one hand, thereby optimizing the overall height design of the water softener, making it more suitable for installation in areas with limited space, such as under a kitchen cabinet (commonly known as "under-cabinet installation"), avoiding cutting the floor or adjusting the direction of the pipeline; on the other hand, the risk of shrinkage and deformation of the cross-section of the transverse channel is low, which is conducive to supporting high instantaneous flow, so as to meet the large flow demand of the water softener; on the other hand, there is no water accumulation in the vertical section of the transverse channel when the machine is shut down, reducing the retention of scale or particulate matter, thereby avoiding the deposition of impurities.

[0084] Optionally, the water inlet channel 101 is provided with a water inlet connector 71 (see Figure 1 ), the water inlet connector 71 is bent and extended downward. In this way, on the one hand, the external water inlet pipe can be prevented from occupying the space above the side of the valve body 1, and the overall height design of the water softener can be optimized, making it more suitable for installation in areas with limited space, such as under a kitchen cabinet (commonly known as "under-cabinet installation"); on the other hand, compared with directly adopting a transversely extended water inlet connector 71, it can also avoid the external water inlet pipe significantly increasing the transverse width required for the product, which will also be detrimental to the installation of the water softener in a narrow space.

[0085] Optionally, the outlet of the water outlet channel 105 is provided with a water outlet connector 72 (see Figure 1 ), the water outlet connector 72 is bent and extended downward. In this way, on the one hand, the external water outlet pipe can be prevented from occupying the space above the side of the valve body 1, and the overall height design of the water softener can be optimized, making it more suitable for installation in areas with limited space, such as under a kitchen cabinet (commonly known as "under-cabinet installation"); on the other hand, compared with directly adopting a transversely extended water outlet connector 72, it can also avoid the external water outlet pipe significantly increasing the transverse width required for the product, which will also be detrimental to the installation of the water softener in a narrow space.

[0086] Optionally, the brine injection channel 106 is provided with a salt box connector 73 (see Figure 1 ), the salt tank joint 73 is bent and extended downward. In this way, on the one hand, the salt tank 300 can be prevented from occupying the space above the soft water valve side in the water softener, and the overall height design of the water softener can be optimized, making it more suitable for installation in areas with limited space, such as under a kitchen cabinet (commonly known as "under-cabinet installation"). The salt tank 300 can provide a stable foundation below, reducing the risk of vibration or displacement, thereby extending the life of the equipment. On the other hand, compared with directly adopting a laterally extended salt tank joint 73, it can also avoid significantly increasing the lateral width required for the product, which will also be detrimental to the installation of the water softener in a narrow space.

[0087] In this embodiment, the water inlet joint 71, the water outlet joint 72 and the salt box joint 73 are all bent and extended downward; however, the present design is not limited to this. In some other embodiments, the water inlet joint 71, the water outlet joint 72 and the salt box joint 73 may also be only partially bent and extended downward.

[0088] In one embodiment, referring to Figures 2 to 4 The valve body 1 includes a valve body 15 and a valve base 16 that are spliced together. The valve base 16 is provided with the soft tank interface 161. The splicing surface of the valve body 15 and the valve base 16 passes through the mixed water flow channel 17 to facilitate the formation of the mixed water flow channel 17.

[0089] Optionally, the joint surface between the valve body 15 and the valve base 16 is configured as a plane. It is understandable that the flatness of a plane is easy to be higher, and the higher the flatness, the easier it is to achieve high sealing. In this embodiment, by configuring the joint surface between the valve body 15 and the valve base 16 as a plane, it is beneficial to achieve a high-sealing joint between the valve body 15 and the valve base 16, thereby reducing the risk of leakage of the valve body 1. In addition, configuring the joint surface as a plane is also beneficial to the alignment connection between the valve body 15 and the valve base 16, and is conducive to achieving accurate alignment, so as to reduce the risk of leakage caused by misalignment between the valve body 15 and the valve base 16.

[0090] Optionally, the valve body 15 and the valve seat 16 are welded. This welding provides a stable structure, which helps improve the structural strength and stability of the valve body 1. Furthermore, flat welding allows for a large-area connection to be completed at one time, achieving a reliable seal and improving the sealing performance of the valve body 1. Furthermore, the valve body 15 and the valve seat 16 are optionally connected using hot plate welding; however, the present design is not limited thereto. In other embodiments, the valve body 15 and the valve seat 16 may also be connected using ultrasonic welding, laser welding, or other methods.

[0091] Optionally, refer to Figures 2 to 4 、 Figure 18 、 Figure 19 The valve body 15 is provided with a first dividing rib 151 on one side close to the valve base 16, which cooperates with the grille assembly 2 to separate a plurality of water passage chambers 111. The valve base 16 is provided with a second dividing rib 162 corresponding to each first dividing rib 151. The first dividing rib 151 has a first rib surface 1511 and a second rib surface 1512 opposite to each other in the radial direction of the valve cavity 11. The grille assembly 2 is sealed and abutted against the first rib surface 1511, and the second dividing rib 162 is fixedly connected to the second rib surface 1512.

[0092] In the technical solution of this embodiment, the valve body 15 is provided with a first dividing rib 151 on a side adjacent to the valve base 16 for separating the plurality of water passage chambers 111. The first rib surface 1511 of the dividing rib abuts the grille assembly 2. That is, each first dividing rib 151 abuts a corresponding support ring 24 of the grille assembly 2. As a result, the outer periphery of the grille assembly 2 abuts only against the valve body 15. This eliminates the effect of the abutment between the outer periphery of the grille assembly 2 and the inner periphery of the valve chamber 11 on the connection between the valve body 15 and the valve base 16, thereby reducing the probability of cracking at the connection between the valve body 15 and the valve base 16. In other words, it can reduce the probability of the valve body 1 bursting, thereby increasing the service life of the soft water valve. In addition, the fixed connection between the second dividing rib 162 and the second rib surface 1512 also increases the connection area between the valve body 15 and the valve base 16, thereby increasing the connection strength between the valve body 15 and the valve base 16, further reducing the probability of the valve body 1 bursting, and increasing the service life of the soft water valve.

[0093] Optionally, the splicing surface is parallel to the axis of the valve cavity 11. Parallel in the present invention generally refers to parallel or nearly parallel, with nearly parallel generally referring to a slight inclination between the two directions, for example, an inclination of less than or equal to 20°. By aligning the splicing surface with the axis of the valve cavity 11, this embodiment can achieve a uniform shape among the multiple first dividing ribs 151, ensuring that each first dividing rib 151 has sufficient structural and support strength, thereby promoting uniformity in the product's structural strength.

[0094] Optionally, the piston 3 includes a first piston body 31 and a second piston body 32 connected to each other, the diameter of the first piston body 31 is larger than the diameter of the second piston body 32, the first piston body 31 is provided with a water passage 311 that passes through both ends, and the water level on the outer periphery of the piston 3 includes a first water ring groove 312 provided on the outer periphery of the first piston body 31 and a second water ring groove 321 provided on the outer periphery of the second piston body 32.

[0095] See also Figure 9 、 Figure 11 and Figure 12In an embodiment of the present invention, the multiple water channel modes include a water production mode. In the water production mode, the water inlet chamber 112 is connected to the side wall chamber 113 through the first water ring groove 312, and the central chamber 115 is connected to the water outlet chamber 116 through the connection between the first piston body 31 and the second piston body 32. The outer periphery of the first piston body 31 blocks the sewage discharge chamber 114, and the outer periphery of the second piston body 32 blocks the water injection and salt absorption chamber 117; raw water flows into the water inlet chamber 112 through the water inlet channel 101, and flows into the soft water tank 200 through the side wall chamber 113 and the side wall channel 102 in turn to be softened; the softened soft water flows out of the soft water valve through the central channel 104, the central chamber 115, the water outlet chamber 116 and the water outlet channel 105 in turn.

The outer periphery of the first piston body 31 blocks the sewage discharge chamber 114; raw water flows into the water inlet chamber 112 through the water inlet channel 101, and sequentially passes through the side wall chamber 113. The softened water flows through the central channel 104 and the central cavity 115 into the water outlet cavity 116, and then a portion of the softened water flows out of the softening valve through the water outlet channel 105, and the other portion of the softened water flows into the water injection and salt absorption cavity 117, and then is injected into the salt tank 300 through the water injection and salt absorption channel 106. In this way, on the one hand, the preparation of soft water can be continuously realized when injecting water into the salt tank 300, and on the other hand, the water entering the salt tank 300 is softened soft water, which can reduce the consumption of salt in the salt tank 300.

The direction indicated by the arrow in the figure is the water flow direction of the water softener in water injection mode.

[0097] See also Figure 9 、 Figure 11 and Figure 14In an embodiment of the present invention, the multiple water channel modes include a forward wash mode. In the forward wash mode, the water inlet chamber 112 communicates with the side wall chamber 113 and the water outlet channel 105 via the water flow channel 311. The central chamber 115 communicates with the sewage discharge chamber 114 via the first water flow annular groove 312. The outer periphery of the second piston body 32 blocks the water injection and salt absorption chamber 117. Raw water flows into the water inlet chamber 112 through the water inlet channel 101. A portion of the raw water flows into the water outlet chamber 116 via the water flow channel 311 and is discharged from the soft water valve via the water flow channel 105. The other portion flows into the side wall chamber 113 and flows into the soft water tank 200 via the side wall channel 102 to clean the soft water tank 200. The cleaned sewage is discharged from the soft water valve via the central channel 104, the central chamber 115, the sewage discharge chamber 114, and the sewage discharge channel 103 in sequence. Figure 14 This is a simplified structural diagram of the water softener in forward wash mode. The direction indicated by the arrow in the figure is the water flow direction of the water softener in forward wash mode.

[0098] See also Figure 9 、 Figure 11 and Figure 15 In an embodiment of the present invention, the plurality of water channel modes include a backwash mode. In the backwash mode, the water inlet chamber 112 is connected to the water outlet channel 105 through the water passage 311, the side wall chamber 113 is connected to the sewage discharge chamber 114 through the first water ring groove 312, and the central chamber 115 is connected to the water outlet chamber 116 through the connection between the first piston body 31 and the second piston body 32.

The other portion flows into the central chamber 115 and flows into the soft water tank 200 through the central channel 104 to clean the soft water tank 200. The cleaned wastewater flows out of the soft water valve in sequence through the side wall channel 102, the side wall chamber 113, the sewage chamber 114 and the sewage channel 103. Figure 15 , Figure 15 This is a simplified structural diagram of the water softener in backwash mode. The direction indicated by the arrow in the figure is the water flow direction of the water softener in backwash mode.

[0099] In one embodiment, reference is made to Figures 1 to 7The valve body 1 is further provided with a jet channel 107 and a bypass channel 14. The jet channel 107 is provided between the water inlet chamber 112 and the side wall chamber 113, and / or between the central chamber 115 and the water outlet chamber 116; one end of the bypass channel 14 is connected to the water injection and salt absorption chamber 117, and the other end is connected to the jet channel 107; the soft water valve also includes an ejector 4 provided in the jet channel 107.

[0100] Optionally, the joint surface between the valve body 15 and the valve base 16 passes through the bypass channel 14 to facilitate the formation of the bypass channel 14 .

[0101] Optionally, the jet channel 107 includes a first jet channel 107a and a second jet channel 107b, the first jet channel 107a is arranged between the water inlet chamber 112 and the side wall chamber 113, and the second jet channel 107b is arranged between the central chamber 115 and the water outlet chamber 116, the soft water valve also includes a plug, one of the ejector 4 and the plug is arranged in the first jet channel 107a, and the other is arranged in the second jet channel 107b, one end of the bypass channel 14 is connected to the water injection and salt absorption chamber 117, and the other end is connected to both the first jet channel 107a and the second jet channel 107b.

[0102] See also Figure 9 、 Figure 11 and Figure 16 In an embodiment of the present invention, the plurality of water channel modes include a downstream regeneration mode. In the downstream regeneration mode, the ejector 4 is provided in the first jet channel 107a, and the second jet channel 107b is blocked by a plug, so that the central cavity 115 and the water outlet cavity 116 cannot communicate with the bypass channel 14. The water inlet cavity 112 is connected to the water outlet channel 105 through the water passage 311. The water inlet cavity 112 and the side wall cavity 113 are both connected to the first jet channel 107a.

The central cavity 115 is connected to the sewage discharge cavity 114 through the first water passage annular groove 312.

The regenerated waste water is discharged from the soft water valve in sequence through the central channel 104, the central chamber 115, the sewage chamber 114 and the sewage channel 103. Figure 16 , Figure 16 This is a simplified structural diagram of the water softener in the downstream regeneration mode. The direction indicated by the arrow in the figure is the water flow direction of the water softener in the downstream regeneration mode.

[0104] See also Figure 9 、 Figure 11 and Figure 17 In an embodiment of the present invention, the multiple water channel modes include a countercurrent regeneration mode. In the countercurrent regeneration mode, the first jet channel 107a is blocked by a plug so that the water inlet chamber 112 and the side wall chamber 113 cannot be connected to the bypass channel 14. The ejector 4 is arranged in the second jet channel 107b. The water inlet chamber 112 is connected to the water outlet channel 105 through the water passage 311. The water outlet chamber 116 and the central chamber 115 are both connected to the second jet channel 107b.

The regenerated waste water is discharged from the soft water valve in sequence through the side wall channel 102, the side wall cavity 113, the sewage chamber 114 and the sewage channel 103. Figure 17 , Figure 17This is a simplified structural diagram of the water softener in countercurrent regeneration mode. The direction indicated by the arrow in the figure is the water flow direction of the water softener in countercurrent regeneration mode.

[0106] In one embodiment, please refer to Figure 20 and Figure 21 The grille assembly 2 includes a plurality of grille units 21 sequentially spliced and arranged along the axial direction of the valve chamber 11, and an outer sealing ring groove 211 for installing the outer sealing ring 22 is spliced between two adjacent grille units 21; the grille assembly 2 has a pre-installed state, in which a widened gap 212 can be formed between two adjacent grille units 21, and the width of the widened gap 212 is smaller than the cross-sectional diameter of the outer sealing ring 22;

[0107] When the cavity opening of the valve cavity 11 is in an open state, the grille assembly 2 is installed to the valve cavity 11 in the pre-installed state, widening the gap 212 and widening the outer sealing ring groove 211 to provide a larger deformation space for the outer sealing ring 22; when the driving mounting seat 51 is used to cover the cavity opening of the valve cavity 11, the driving mounting seat 51 abuts against the grille assembly 2 to eliminate the widened gap 212, so that the outer sealing ring 22 is pressed against the cavity wall of the valve cavity 11.

[0108] Specifically, multiple grille units 21 are spliced together in sequence. To facilitate the assembly of the grille assembly 2, during actual assembly, the grille units 21 are often spliced together first, and then the grille assembly 2 is installed as a whole into the valve cavity 11. That is, the multiple grille units 21 and the outer sealing ring 22 are assembled first, and then the grille assembly 2 is installed into the valve cavity 11. Therefore, if the multiple grille units 21 are directly spliced into place, the outer sealing ring 22 is clamped by the outer sealing ring groove 211. In order to ensure the sealing strength, the outer sealing ring 22 and the valve cavity 11 usually adopt an interference fit. As a result, when the grille assembly 2 is actually installed, the friction between the outer sealing ring 22 and the cavity wall of the valve cavity 11 is relatively large, making it difficult to insert the grille assembly 2 into the valve cavity 11. It is also easy to cause the outer sealing ring 22 to shift, which increases the difficulty of installing the grille assembly 2.

[0109] The grille assembly 2 in the present scheme is installed into the valve cavity 11 in a pre-installed state. The existence of the widened gap 212 can further increase the width of the outer sealing ring groove 211 along the axial direction of the valve cavity 11, thereby providing a larger deformation space for the outer sealing ring 22, thereby reducing the friction between the outer sealing ring 22 and the cavity wall of the valve cavity 11 during assembly, making it easier for the grille assembly 2 to be installed into the valve cavity 11, and reducing the probability of the outer sealing ring 22 falling out of the outer sealing ring groove 211; and the existence of the widened gap 212 can also further increase the radial depth of the outer sealing ring groove 211 along the valve cavity 11, thereby allowing more of the outer sealing ring 22 to be installed into the outer sealing ring groove 211, which helps to reduce the outer diameter of the grille assembly 2 at the outer sealing ring 22, thereby reducing the friction between the outer sealing ring 22 and the cavity wall of the valve cavity 11, thereby further facilitating the grille assembly 2 to be installed into the valve cavity 11. Furthermore, the width of the widened gap 212 is smaller than the cross-sectional diameter of the outer sealing ring 22 , thereby reducing the possibility of the outer sealing ring 22 being stuck in the widened gap 212 while reducing the difficulty of installing the grille assembly 2 .

[0110] When the drive mounting seat 51 covers the cavity opening of the valve cavity 11, the drive mounting seat 51 abuts against the grille assembly 2, so that under the pressing action of the drive mounting seat 51, the widened gap 212 is eliminated, and the depth and width of the outer sealing ring groove 211 are reduced, so that the two adjacent grille units 21 can clamp the sealing ring groove 516 together, and the outer sealing ring 22 can be pressed against the cavity wall of the valve cavity 11, thereby facilitating the installation of the grille assembly 2 and ensuring the sealing strength between the grille assembly 2 and the cavity wall of the valve cavity 11.

[0111] In one embodiment, please refer to Figure 16 and Figure 17 The piston 3 includes a first piston 33 and a second piston 34, both of which are provided with a first water-passing annular groove 312. The axial position of the first water-passing annular groove 312 on the first piston 33 is different from the axial position of the second piston 34. Either the first piston 33 or the second piston 34 is installed in the grille assembly 2.

[0112] The various water channel modes include a regeneration water channel mode. When the first piston 33 is installed in the grille assembly 2, in the regeneration water channel mode, the first water ring groove 312 connects the central cavity 115 and the sewage cavity 114 to achieve downstream regeneration; when the second piston 34 is installed in the grille assembly 2, in the regeneration water channel mode, the first water ring groove 312 connects the side wall cavity 113 and the sewage cavity 114 to achieve countercurrent regeneration.

[0113] That is, the soft water valve in this solution can be either a downstream regeneration valve or a reverse flow regeneration valve. From the structural perspective of the soft water valve, the downstream regeneration valve and the reverse flow regeneration valve only have different structures of the first piston 33 and the second piston 34, while the valve body 1, the grid assembly 2 and other structures are exactly the same. That is, the downstream regeneration valve and the reverse flow regeneration valve can share structures such as the valve body 1 and the grid assembly 2. Therefore, in actual production, the downstream regeneration valve and the reverse flow regeneration valve can be realized by producing the same valve body 1, thereby saving the cost of a set of molds, which helps to save the processing cost of the soft water valve. The only difference between the first piston 33 and the second piston 34 is that the axial position of the first water-passing ring groove 312 on the first piston 33 is different from the axial position on the second piston 34, that is, the partial water-passing levels on the first piston 33 and the second piston 34 are different. Therefore, during the actual production of the piston 3, only the position of the first water-passing ring groove 312 needs to be adjusted to simultaneously process the downstream regeneration valve and the reverse regeneration valve. Compared with the prior art, in which the structures of the downstream regeneration valve and the reverse regeneration valve are processed separately and then assembled separately, this solution can not only improve the processing efficiency, but also save the cost of a set of molds, thereby reducing the cost of the soft water valve.

[0114] The present invention also proposes a water softener, which includes a water softener valve. The specific structure of the water softener refers to the above embodiment. Since this water softener adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0115] In one embodiment, referring to Figure 1 The water softener also includes a display screen 400, located on one side of the water softener valve. Serving as the core interface for human-computer interaction, the display screen 400 provides real-time feedback on the device's operating status, as well as multiple functions such as intelligent management, fault warning, and user experience optimization. Compared to the technical solution of stacking the display screen on the upper side of the water softener valve, this embodiment places the display screen 400 on one side of the water softener valve, which helps optimize the overall height design of the water softener, making it more suitable for installation in space-constrained areas, such as under kitchen cabinets (commonly known as "under-cabinet installation").

[0116] The above description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
