[0133] In the related art, a water softener utilizes cation exchange resins to remove calcium and magnesium ions from water, reducing the hardness of the raw water and thereby softening hard water. Water softeners are currently widely used in industrial and energy systems and possess a strong device nature. In household use, the soft water produced by water softeners typically reduces scale buildup in water heating equipment such as water heaters, wall-mounted boilers, and electric water heaters, as well as in bathrooms. It also prevents pipe blockages, reduces the loss of heat exchange efficiency in heating equipment, reduces detergent usage, and is more skin-friendly, resulting in softer, more vibrantly colored clothes.

[0134] The applicant discovered that in related art water softening equipment, the water distributor assembly is located within a tank assembly, which contains resin. Under the influence of gravity, the resin stacks up, resulting in low water production and recycling efficiency. Furthermore, the water distributor assembly in water softening equipment typically has a small disk diameter, limiting the water distribution area to the disk radius and failing to cover the entire cross-section of the tank assembly. This results in low resin utilization for water production and recycling, preventing the resin from fully realizing its performance.

[0135] As shown in Figures 1 to 8, the present application provides a water distributor assembly 100, comprising a disc 110 and a bracket 120. It should be noted that the water distributor assembly 100 is applied to the tank assembly of the water softening equipment, and the tank assembly is filled with resin. The water distributor assembly 100 can evenly distribute the incoming water flow in the tank assembly to ensure that the water flow can evenly flow through the resin layer, thereby improving the efficiency and uniformity of the exchange between ions in the water and the resin layer. At the same time, the water distributor assembly 100 also prevents the resin particles from flowing out of the tank with the water, that is, ensures that the resin particles remain in the tank while allowing the water flow to pass through. In addition, the water distributor assembly 100 can also serve as a supporting layer to prevent the resin particles from moving due to the impact of the water flow, thereby maintaining the stability and effective working volume of the resin layer.

[0136] Specifically, as shown in Figures 1 to 3, the periphery of the disc body 110 is adapted to abut the inner wall of the tank assembly. The disc body 110 includes a plurality of vertical ribs 111 and a plurality of circular ribs 112. The plurality of circular ribs 112 are arranged concentrically, with the vertical ribs 111 connecting any two adjacent circular ribs 112. A bracket 120 is disposed on one side of the disc body 110 and is used to support the disc body 110. The bracket 120 includes a plurality of connecting ribs 121, each of which is connected to the same circular rib 112 at one end. The plurality of connecting ribs 121 are spaced apart circumferentially around the circular rib 112, and each connecting rib 121 extends along the axis of the circular rib 112. A hollow portion is formed between any two adjacent connecting ribs 121. When water flows from the water distributor assembly 100 into the resin layer, the hollow portion guides the water flow radially outward, thereby evenly distributing the water flow across the cross-section of the tank body. The filter screen covers the disc body 110 to prevent the resin particles from leaking out of the disc body 110 , and the filter screen can also provide additional filtering effect to ensure the purity of the output water.

[0137] In addition, in some examples, the distance between any two adjacent connecting ribs 121 is equal, further guiding the water flow evenly.

[0138] According to the water distributor assembly 100 of the embodiments of the present application, by providing a bracket 120 on the disk body 110 and providing connecting ribs 121 on the bracket 120, a hollow portion is formed between any two adjacent connecting ribs 121. When water flows from the water distributor assembly 100 into the resin layer, the hollow portion guides the water flow, guiding the water flow to flow radially outward. And the distance between any two adjacent connecting ribs 121 is equal, so that the water flow can be evenly distributed over the cross-section of the tank body, improving the efficiency and uniformity of the exchange between the ions in the water flow and the resin layer.

[0139] As shown in FIG. 1, in some embodiments of the present application, in the radially outward direction of the circular rib 112, the distance between any two adjacent circular ribs 112 gradually increases. In one embodiment of the present application, as shown in FIG. 1, there are eight vertical ribs 111, and the eight vertical ribs 111 are evenly arranged in the circumferential direction, and each vertical rib 111 extends in the radial direction of the circular rib 112. There are 4 circular ribs 112, and the four circular ribs 112 are concentrically distributed. And a fan-shaped hole is formed between the circular rib 112 and the vertical rib 111. In the radially outward direction of the disk body 110, the radial widths of the fan-shaped holes are L0, L1, and L2 in sequence, where L0 < L1 < L2. The water flow can be split through the fan-shaped holes on the water distributor assembly 100. Among them, in the radially outward direction of the disk body 110, the water flow rate that can pass through the fan-shaped holes becomes larger and larger, allowing more water flow to pass through the outer peripheral portion of the disk body 110, and relatively reducing the water flow rate passing through the central portion of the disk body 110.

[0140] In this way, when the water flow passes through the fan-shaped holes formed by the vertical ribs 1, the water flow is guided and dispersed to various regions inside the tank body, and the water flow can be evenly distributed over the cross-section of the tank body. This not only ensures that the water flow can fully contact the resin layer in the tank body, thereby maximizing the ion exchange efficiency of the resin, but also makes the flow rate distribution of the water flow more uniform when passing through the resin layer, reducing the problems of uneven resin utilization or channel flow caused by uneven water flow.

[0141] As shown in FIG. 3, in some embodiments of the present application, the bracket 120 further includes a support rib 122, the support rib 122 is adapted to contact the bottom of the tank body assembly, and the other end of each connecting rib 121 is connected to the support rib 122. The support rib 122 can increase the structural stability of the entire bracket 120. When water flows through the water distributor assembly 100, a certain pressure may be exerted on the bracket 120. The presence of the support rib 122 can prevent the bracket 120 from unnecessary deformation or bending, ensuring that the bracket 120 maintains its original shape and stability.

[0142] As shown in FIG3 , in some embodiments of the present application, the support ribs 122 are annular ribs that can form a continuous annular support structure at the bottom of the tank assembly, ensuring that the support ribs 122 are evenly distributed throughout the bottom area of ​​the tank assembly, thereby providing uniform support for the tray 110 and helping to maintain the stability of the entire water distributor assembly 100. Compared to a single central support point, the annular ribs can evenly distribute their weight throughout the bottom area of ​​the tank assembly, which helps avoid single-point pressure in the bottom area of ​​the tank assembly and reduces the risk of damage to the bottom area of ​​the tank.

[0143] In one embodiment of the present application, at least one connecting rib 121 is provided with a chamfer. The process chamfer can increase the water diversion effect of the connecting rib 121, thereby improving and guiding the path of the water flow to achieve a more efficient and uniform distribution of the water flow. The chamfer is formed on the water flow contact surface of the connecting rib 121, and its angle and shape enable the water flow to produce a smooth turning effect when contacting the connecting rib 121. The chamfer not only reduces the direct impact of the water flow on the connecting rib 121, thereby reducing the wear on the connecting rib 121, but also helps to reduce the turbulence and uneven flow velocity distribution that may be generated when the water flow passes through the resin layer. Of course, the setting method of the chamfer is not limited to this. In other embodiments of the present application, the chamfer can also be set on the supporting rib 122, or, in other embodiments, a chamfer is also set on at least one vertical rib 111, or, the chamfer can also be set on at least one circular rib 112.

[0144] As shown in Figures 4 and 5 , in one embodiment of the present application, the connecting ribs 121 can also be multiple support columns 123. The number of support columns 123 can be 4-8. For example, as shown in Figure 4 , the number of support columns can be 4. Thus, by designing multiple support columns, the bracket 120 can adapt to tank assemblies of different sizes and shapes, improving the adaptability of the bracket 120. Furthermore, the multiple support columns 123 help evenly distribute the pressure of the water flow on the bracket 120, avoiding single-point pressure and stress concentration at the bottom of the tank body 200, and improving the durability of the tank bottom.

[0145] In some embodiments of the present application, the mesh size of the filter is 80-400 mesh. For example, the mesh size of the filter can be 100 mesh, so that the filter can block resin particles while maintaining the smoothness of water flow, avoiding water flow blockage or pressure loss caused by too small filter pores.

[0146] As shown in Figure 9, in one embodiment of the present application, the disc 110 further includes a perforated plate 117, which is connected to both the circular ribs 111 and the vertical ribs 112. The perforated plate 117 is provided with a plurality of small holes 1171. The small holes 1171 are arranged radially outward from the disc 110, with at least one such small hole 1171 located within the area enclosed by any two adjacent vertical ribs 112 and any two adjacent partial circular ribs 111. The small holes 1171 on the perforated plate 117 further disperse the water flow, making it more evenly distributed within the tank 210. This increases the contact area between the water flow and the resin, thereby improving the efficiency of ion exchange. Furthermore, the provision of the small holes 1171 prevents the resin particles from being displaced by the impact of the water flow, thereby maintaining the stability and effective working volume of the resin layer. Furthermore, the provision of the perforated plate 117 enhances the structural stability of the disc 110, improves its load-bearing capacity, and prevents deformation of the disc 110 under the impact of the water flow.

[0147] As shown in Figure 9, in one embodiment of the present application, multiple small holes 1171 are arranged in concentric circles around the center of the disc 110, further enabling the disc 110 to evenly distribute the water. Furthermore, by adjusting the number and size of small holes 1171, the water distribution can be adjusted, making the water flow more uniform across the entire cross-section, further improving the water distribution effect during regeneration and increasing water production.

[0148] As shown in Figures 6 and 7, in some embodiments of the present application, the water distributor assembly 100 further includes a central tube 130. The water flow softened by the replacement reaction with the resin can flow out of the tank assembly through the central tube 130, or, when the resin is regenerated, the regeneration liquid can flow from the central tube 130 into the tank assembly and enter the resin layer. The center of the disk 110 has a plug hole 113, the hole wall of the plug hole 113 is connected to the innermost circular rib 112, and the central tube 130 is inserted into the plug hole 113. The size and shape of the plug hole 113 match the center tube 130, so that the center tube 130 can be stably inserted into the plug hole 113, reducing the problem of loosening or wear between the center tube 130 and the disk 110 caused by water flow impact and mechanical vibration.

[0149] As shown in Figures 3 and 7, in some embodiments of the present application, the wall of the insertion hole 113 has a stepped surface 114, and the center tube 130 abuts against the stepped surface 114, so that the center tube 130 can limit the position of the disk 110 and prevent the disk 110 from moving in the axial direction due to the action of water pressure. In addition, by providing the stepped surface 114, the installer can determine the correct insertion depth of the center tube 130, avoiding over-insertion or under-insertion of the center tube 130 into the insertion hole 113, making the installation process more efficient and accurate. When the center tube 130 abuts against the stepped surface 114, the position of the water distributor assembly 100 in the tank can be determined, helping to ensure the correct installation position of the water distributor assembly 100, thereby ensuring the performance of the water distributor assembly 100. In addition, the stepped surface 114 can serve as a sealing surface, increasing the contact area between the center tube 130 and the insertion hole 113, facilitating the installation of the sealing ring 116 or other sealing components, thereby improving the overall sealing performance of the water distributor assembly 100.

[0150] As shown in FIG3 , in some embodiments of the present application, the hole depth of the plug hole 113 is greater than the thickness of the circular rib 112. In this way, when the central tube 130 is inserted into the plug hole 113, it can ensure that the central tube 130 has a deeper insertion length, thereby providing better support and positioning for the central tube 130. In addition, the hole depth being greater than the thickness of the circular rib 112 can also reduce the possibility of stress concentration on the edge of the circular rib 112 due to plugging, thereby preventing damage or deformation of the circular rib 112 and improving the durability and reliability of the entire water distributor assembly 100 structure. The deeper plug hole 113 can also provide more operating space for installing and removing the central tube 130.

[0151] As shown in Figure 6, the present application also provides a tank assembly, including the above-mentioned water distributor assembly 100 and a tank body 200. The water distributor assembly 100 is arranged in the tank body 200, and the tank body 200 is also provided with a resin layer. It should be noted that resin is provided in the tank body 200, and disks 110 are provided at both ends of the central tube 130. The water distributor assembly 100 can perform forward washing and backwashing on the resin layer in the tank body 200. During forward washing, the water to be softened is diverted from the disk 110 at one end of the central tube 130 to the resin layer in the tank body 200. After the softened water undergoes ion exchange with the resin layer, it becomes soft water and finally flows out of the tank body 200 from the central tube 130. During backwashing, the regeneration liquid enters the tank body 200 from the central tube 130, and then is diverted to the resin layer in the tank body 200 through the disk 110 to regenerate the resin layer.

[0152] The tank assembly provided in the present application includes the above-mentioned water distributor assembly 100, and therefore also has the beneficial effects of the above-mentioned water distributor assembly 100, which will not be described in detail here.

[0153] As shown in Figure 4 , in some embodiments of the present application, the periphery of the disc 110 is provided with a mating portion that forms an interference fit with the inner wall of the tank body 200. This prevents resin leakage from the gap between the disc 110 and the tank body 200, improves the positioning accuracy of the disc 110 on the tank body 200, and enhances the vibration resistance of the water distributor. This ensures that the disc 110 remains fixed in place during operation of the water softener, reducing the possibility of displacement due to water pressure or mechanical vibration.

[0154] In addition, since the mating portion can directly interfere with the inner wall of the tank body 200, the need for additional fixings, such as screws or adhesives, when installing the water distributor can be reduced, thereby simplifying the assembly process of the water distributor assembly 100 and improving assembly efficiency. Furthermore, the interference fit between the mating portion and the tank body 200 can form a tight interface between the water distributor and the tank body 210, thereby preventing leakage of resin particles. Due to the stability of the water distributor position, it can be ensured that water flows evenly through the water distributor and effectively contacts the resin layer, thereby ensuring the uniformity and effectiveness of ion exchange during the water treatment process.

[0155] As shown in Figure 8, in some embodiments of the invention, the peripheral wall of the disc body 110 is provided with a sealing groove, and the mating portion is a sealing ring 116 provided in the sealing groove, and the sealing ring 116 abuts against the inner wall of the tank body 200. In this way, the sealing between the disc body 110 and the tank body 200 can be increased, preventing the resin from leaking to the outside of the water distributor assembly 100, thereby improving the accuracy and efficiency of water treatment. In addition, the provision of the sealing ring 116 can also prevent sediment, particles or other impurities that may be brought in by the water flow from entering the interior of the tank body assembly, thereby providing additional protection for the water distributor assembly 100 and the resin layer. Among them, the sealing ring 116 can be made of silicone or other rubber sealing materials through double-material injection molding and integrated with the disc body 110 to achieve sealing and prevent resin leakage.

[0156] As shown in FIG4 , in some embodiments of the present application, the mating portion is a mating boss provided on the peripheral wall of the disc body 110. The mating boss forms an interference fit with the inner wall of the tank body 200, thereby improving the positioning accuracy of the water distributor on the tank body 200. In addition, when the disc body 110 is installed in the tank body 200, a stable interference fit can be achieved by simply pressing or tapping, simplifying the installation process.

[0157] As shown in FIG6 , in some embodiments of the present application, the tank body 200 includes a tank body 210 and a cover 220, the disc 110 abuts against the inner wall of the tank body 210, the cover 220 is provided with an insertion portion 221, and the insertion portion 221 abuts against the tank body 210, so that the cover 220 and the tank body 210 are detachably connected. In this way, a good sealing effect can be provided between the cover 220 and the tank body 210, preventing leakage of water or resin, and ensuring that the water quality during the water treatment process is not polluted. The bracket 120 abuts against the inner wall of the cover 220, and the bracket 120 abuts against the inner wall of the cover 220, which can provide additional support for the disc 110, so that the water distributor assembly 100 remains stable under the pressure of the water flow, and prevents deformation or displacement caused by gravity or fluid dynamics.

[0158] As shown in Figure 8, in some embodiments of the present application, the free end of the insertion portion 221 abuts against the periphery of the disk body 110, so that the insertion portion 221 can provide additional mechanical support for the water distributor assembly 100, ensure that the disk body 110 is correctly positioned in the tank body 200, ensure the stability of the disk body 110 in the tank body 200, and prevent the disk body 110 from shifting, thereby maintaining the uniformity of water flow through the resin layer.

[0159] As shown in FIG8 , in some embodiments of the present application, the free end of the insert 221 has a groove 222 , and the periphery of the disc 110 extends axially with a protrusion 115 , which cooperates with the groove 222 to allow the cover 220 to limit the position of the disc 110 , thereby further restricting the movement of the disc 110 within the tank body, improving the stability of the entire water distributor assembly 100 , and effectively preventing the disc 110 from moving under fluctuations in water flow and pressure, thereby affecting water distribution. Using the groove 222 and the protrusion 115 to limit the position of the disc 110 can reduce component wear or damage caused by improper installation or long-term use.

[0160] As shown in Figures 6 and 7, in some embodiments of the present application, the inner wall of the cover body 220 is a spherical surface, and the bracket 120 abuts the spherical surface. In this way, the spherical surface can provide a good water flow guiding effect, so that the water body can flow smoothly along the spherical surface, reduce the flow resistance and the generation of vortices, and improve the stability and uniformity of the water flow. The design of the spherical surface can reduce the dead corners of the water flow better than the right-angle or sharp-angle design, which helps to avoid the formation of local circulation of water flow on the inner wall of the cover body 220, reduces the formation of stagnation areas, and thus improves the water treatment effect. The spherical surface is easier to clean than a flat surface or other shapes. The spherical surface has no sharp corners, which reduces the chance of dirt and biofilm adhesion, and maintains the long-term cleanliness and efficient operation of the water distribution system. Since the spherical surface is a continuous curved surface, it has better structural strength and stability when under pressure, which helps to improve the durability of the equipment.

[0161] The present application also provides a water softening device (not shown in the figure), which includes the above-mentioned tank assembly (not shown in the figure), waterway component (not shown in the figure), and control valve (not shown in the figure). The waterway component is connected to the tank body 200 of the tank assembly, and the control valve is connected to the waterway component. The control valve is used to control the switching of the waterway in the waterway component.

[0162] The water softening device provided by the present application includes the above-mentioned tank assembly, so it has the beneficial effects of the above-mentioned tank assembly, which will not be elaborated here.

[0163] As shown in FIGS. 10 to 15, the present application also provides a water distributor assembly 100. It should be noted that the water distributor assembly 100 is applied to the tank assembly 10 of the water softening device. The tank assembly 10 is filled with resin. The water distributor assembly 100 can evenly distribute the incoming water flow in the tank assembly 10, ensuring that the water flow can evenly flow through the resin layer, thereby improving the efficiency and uniformity of ion exchange in water. At the same time, the water distributor assembly 10 also plays a role in preventing resin particles from flowing out of the tank body 210 with the water, that is, ensuring that the resin particles remain in the tank while allowing the water flow to pass through. In addition, the water distributor assembly 10 can also serve as a support layer to prevent the resin particles from moving due to the impact of the water flow, maintaining the stability and effective working volume of the resin layer.

[0164] Specifically, as shown in FIGS. 10 and 11, the water distributor assembly 100 includes a disk body 110 and a filter screen. The periphery of the disk body 110 abuts against the inner wall of the tank assembly 10. In this way, the inner wall of the tank assembly 10 can radially limit the disk body 110, preventing the radial movement of the disk body 110 in the tank assembly 10. Among them, the disk body 110 includes a plurality of vertical ribs 111 and a plurality of circular ribs 112. The plurality of circular ribs 112 are concentrically distributed. A vertical rib 111 is connected between any two adjacent circular ribs 112. In the radially outward direction of the circular rib 112, the radius of the outer circular rib 112 is greater than the radius of the inner circular rib 112.

[0165] [[ID=

[0166] In this way, when the water flow enters the tank body assembly 10, after passing through the fan-shaped holes 116-1 formed by the vertical ribs 111 and the circular ribs 112, the water flow is guided and dispersed to various areas inside the tank body 210, so that the water flow can be evenly distributed on the cross-section of the tank body 210. This not only ensures that the water flow can fully contact the resin layer in the tank body 210, thereby maximizing the ion exchange efficiency of the resin, but also makes the flow velocity distribution of the water flow more uniform when passing through the resin layer, reducing the problems of uneven resin utilization or channel flow that may be caused by uneven water flow.

[0167] The filter screen covers the disc body 110, preventing the resin particles from penetrating the filter screen while allowing the broken and finer resin residues to pass through and be discharged. In this way, the resin particles can be protected from being carried out of the tank body 210 by the water flow, and it helps to maintain the structural stability of the resin layer, so that the resin particles can be firmly maintained in the preset position, thereby extending the effective use period of the resin.

[0168] According to the water distributor assembly 100 of the embodiment of the present application, a plurality of vertical ribs 111 and a plurality of circular ribs 112 are provided, and the plurality of circular ribs 112 are distributed in concentric circles. A vertical rib 111 is connected between any two adjacent circular ribs 112, and the distance between any two adjacent circular ribs 112 gradually increases in the radially outward direction of the circular ribs 112. In this way, the water flow through the disc body 110 in the radially outward direction of the disc body 110 increases, thereby ensuring sufficient contact between the water flow and the resin, thereby improving the resin utilization rate.

[0169] As shown in Figure 16, in one embodiment of the present application, the disc body 110 also includes a blocking rib 119, which is distributed in concentric circles with the circular rib 112, and a blocking rib 119 is connected between any two adjacent vertical ribs 111. In this way, the blocking rib 119 can curb a portion of the water flow and prevent the water flow from directly passing through the disc body 110 and entering the interior of the resin layer. As a result, the water flow is guided to diffuse along the circumferential direction of the disc body 110, which not only improves the uniformity of the water flow, but also enhances the water separation capacity of the disc body 110. This improvement ensures that the water flow can have more sufficient contact with the resin, thereby improving the utilization efficiency of the resin and the overall water production. In some embodiments of the present application, the blocking rib 119 is arranged between the two outermost circular ribs 112 of the disc body 110, which can further enhance the water separation capacity of the disc body 110.

[0170] As shown in Figure 13, in one embodiment of the present application, the disc 110 further includes a perforated plate 117, which is connected to both the circular ribs 112 and the vertical ribs 111. The perforated plate 117 is provided with a plurality of small holes 1171. The small holes 1171 are arranged radially outward from the disc 110, with at least one small hole 1171 within the area enclosed by any two adjacent vertical ribs 111 and any two adjacent partial circular ribs 112. The small holes 1171 on the perforated plate 117 further disperse the water flow, making it more evenly distributed within the tank 210, increasing the contact area between the water flow and the resin, and thus improving the efficiency of ion exchange. Furthermore, the provision of the small holes 1171 also prevents the resin particles from being displaced by the impact of the water flow, maintaining the stability and effective working volume of the resin layer. Furthermore, the provision of the perforated plate 117 also enhances the structural stability of the disc 110, improves its load-bearing capacity, and prevents deformation of the disc 110 under the impact of the water flow.

[0171] As shown in Figure 13, in one embodiment of the present application, multiple small holes 1171 are arranged concentrically around the center of the disc 110, further enabling the disc 110 to evenly distribute the water. Furthermore, by adjusting the number and size of small holes 1171, the water distribution can be adjusted to achieve a more uniform flow across the entire cross-section, further improving the water distribution during regeneration and increasing water production.

[0172] As shown in Figures 17, 18, and 19, in one embodiment of the present application, the peripheral surface of the disc 110 is spherical 118. A portion of the inner wall of the tank assembly 10 is configured as an arcuate surface that aligns with the spherical surface 118. The spherical surface 118 abuts the inner wall of the tank assembly 10, limiting the axial position of the disc 110 and preventing axial movement of the disc 110, which could affect water distribution performance. This also seals the mating area between the disc 110 and the tank assembly 10, preventing resin from leaking from the mating area. In one embodiment of the present application, at least one vertical rib 111 is provided with a process chamfer. This process chamfer enhances the water diversion effect of the vertical rib 111, thereby improving and directing the water flow path for more efficient and uniform water distribution. The process chamfer is formed on the water contact surface of the vertical rib 111. Its angle and shape ensure smooth diversion of the water flow upon contact with the vertical rib 111. This chamfer not only reduces the direct impact of water flow on the vertical ribs 111, thereby reducing mechanical wear on the vertical ribs 111, but also helps reduce turbulence and uneven flow velocity distribution that may occur when the water flows through the resin layer. Of course, the setting method of the process chamfer is not limited to this. In other embodiments of the present application, at least one circular rib 112 is provided with a process chamfer.

[0173] By introducing process guide angles, the water flow through the vertical ribs 111 and circular ribs 112 is enhanced, resulting in a more balanced water flow distribution across the cross-section of the tank body 210. This ensures that the water distributor assembly 100 provides more stable and consistent water flow guidance during operation of the water softening system, further improving the contact efficiency of the resin layer and the uniformity of ion exchange.

[0174] In one embodiment of the present application, the mesh size of the filter is 80-400 mesh. For example, the mesh size of the filter can be 300 mesh. In this way, the filter can block the resin particles while maintaining the smoothness of the water flow, avoiding water flow blockage or pressure loss caused by the filter pores being too small. During the operation of the water distributor assembly 100, the filter needs to be able to resist the impact of the water flow, maintain structural integrity, and avoid frequent cleaning or replacement due to blockage. Therefore, the filter screen with a mesh size of 80 to 400 not only meets the requirements of operating efficiency, but also ensures that the maintenance cost of the equipment is relatively low.

[0175] As shown in FIG12 , in one embodiment of the present application, the water distributor assembly 100 further includes a central tube 130, which produces a replacement reaction with the resin so that the softened water can flow out of the tank assembly 10 through the central tube 130. The innermost circular ribs 112 of the disk 110 enclose a plug hole 113, the size and shape of which match those of the central tube 130, so that the central tube 130 can be stably inserted into the plug hole 113, thereby reducing the problem of loosening or wear of the water distributor assembly 100 caused by water flow impact and mechanical vibration. In addition, the sealing performance of the water distributor assembly 100 is improved, reducing the risk of leakage caused by mixing of unsoftened water and softened water in the tank assembly 10.

[0176] As shown in FIG12 , in one embodiment of the present application, a stopper 114-1 is provided on the inner wall of the insertion hole 113 in the radially inward direction of the disk body 110. An abutment portion 121-1 is provided on the periphery of the center tube 130, and the abutment portion 121-1 abuts against the stopper 114-1. In this way, the abutment portion 121-1 can limit the disk body 110 and prevent the disk body 110 from moving in the axial direction due to the impact of water flow or mechanical vibration.

[0177] In addition, the coordinated design of the limiting portion 114-1 and the abutting portion 121-1 in the present application can also improve the assembly efficiency of the water distributor assembly 100. Due to the mutual coordination between the limiting portion 114-1 and the abutting portion 121-1, the installer can easily identify whether the central tube 130 has been installed in place, and when maintenance or replacement of the central tube 130 is required, it can also be quickly and accurately disassembled and reinstalled.

[0178] As shown in FIG12 , in one embodiment of the present application, the abutment portion 121-1 is an annular boss provided on the outer peripheral wall of the central tube 130. Thus, when the central tube 130 is inserted into the disk body 110, the annular boss can block the connection gap between the central tube 130 and the disk body 110, preventing resin from leaking from the connection gap between the central tube 130 and the disk body 110. Of course, the configuration of the abutment portion 121-1 is not limited to a single annular boss. In other embodiments of the present application, there can be multiple abutment portions 121-1, and the multiple abutment portions 121-1 are spaced apart along the outer circumference of the central tube 130. This multi-point abutment structure enhances the stability of the central tube 130 in the insertion hole 113 and provides sealing points at different locations, thereby further improving the sealing performance and durability of the assembly.

[0179] As shown in Figure 14, the present application also proposes a tank assembly 10, including a water distributor assembly 100 and a tank body 200. The water distributor assembly 100 is the above-mentioned water distributor assembly 100, and the water distributor assembly 100 is arranged in the tank body 200. Resin is also provided in the tank body 200, and the tap water is diverted to the inside of the tank body 200 through the disc 110 in the water distributor assembly 100. When the tap water passes through the resin layer, the ion exchange effect in the resin will promote the hardness ions in the tap water, such as calcium ions and magnesium ions, to produce a replacement reaction. Through this exchange reaction, the hardness ions in the water are effectively removed, achieving the purpose of softening the water quality. After the softening treatment is completed, the water flow treated by the resin layer will enter the central tube 130 of the tank assembly 10, so that the water flow can flow out of the tank body 210 from the central tube 130 stably and smoothly.

[0180] According to the embodiment of the present application, the tank assembly 10 includes the above-mentioned water distributor assembly 100 and thus has the beneficial effects of the above-mentioned water distributor assembly 100 , which will not be described in detail here.

[0181] As shown in Figure 15, in one embodiment of the present application, a limiting groove 115-1 is provided on the innermost circular rib 112 located on the disc body 110, and a limiting protrusion 223 is provided in the tank body 200. During the assembly process, the limiting protrusion 223 and the limiting groove 115-1 are interlocked, thereby realizing a fixed connection between the water distributor assembly 100 and the tank body 200.

[0182] This fixed connection method not only simplifies the installation process of the water distributor assembly 100 in the tank body 200 and ensures the accuracy of assembly, but also strengthens the connection strength between the water distributor assembly 100 and the tank body 200, making the position of the water distributor assembly 100 in the tank body 210 more stable, reducing the displacement or falling off of the water distributor assembly 100 due to mechanical vibration or during transportation, and ensuring the stability of the tank body assembly 10 during operation. In addition, the coordinated use of the limiting groove 115-1 and the limiting protrusion 223 also facilitates the inspection or replacement of the water distributor assembly 100. During inspection or replacement, the water distributor assembly 100 only needs to be removed from the limiting groove 115-1.

[0183] As shown in Figure 14, in one embodiment of the present application, the tank body 200 includes a tank body 210 and a cover 220. The resin is disposed within the tank body 210, while the cover 220 is used to seal the tank body 210, ensuring a sealed environment within the tank and protecting the resin. The water distributor assembly 100 is positioned within the tank body 210 to evenly distribute the water entering the tank body 210, thereby promoting the ion exchange process between the tap water and the resin.

[0184] The cover 220 and the tank body 210 are connected by a threaded connection, which simplifies the assembly and disassembly process, while improving the sealing performance of the tank body 210 and preventing the intrusion of external pollutants.

[0185] The limiting protrusion 223 is inside the cover 220, and the water distributor assembly 100 is disposed inside the tank 210. When the cover 220 is threadedly connected to the tank 210, the limiting protrusion 223 cooperates with the corresponding limiting groove 115-1 on the water distributor assembly 100, thereby firmly positioning the water distributor assembly 100 within the tank 210. This fixing method ensures that the water distributor assembly 100 can maintain a static position under water pressure, flow, and other operating conditions, preventing displacement or disengagement due to vibration or impact, and ensuring the normal operation of the water softening equipment.

[0186] Furthermore, the design of the stop protrusion 223 simplifies the manufacturing and assembly process of the tank assembly 10, reducing the possibility of assembly errors. The cooperation between the stop protrusion 223 and the stop groove 115-1 provides an intuitive assembly indicator, allowing the operator to determine whether the assembly is correctly installed. This not only improves assembly efficiency but also reduces maintenance costs.

[0187] The present application also provides a water softening device, comprising a tank assembly 10, a water channel component, and a control valve. The tank assembly 10 is the tank assembly 10 described above, the water channel component is connected to the tank body 200 of the tank assembly 10, and the control valve is connected to the water channel component, and the control valve is used to control the switching of the water channel in the water channel component.

[0188] The water softening device provided in the present application includes the above-mentioned tank assembly 10 and thus also has the beneficial effects of the above-mentioned tank assembly 10 , which will not be described in detail here.

[0189] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the scope of the technical solutions of the present application and should be encompassed by the claims of the present application.
