[0049] In the related art, a water softener is a device that uses cation exchange resin to remove calcium and magnesium ions in water, reduce the hardness of raw water, and thus soften hard water. Water softeners are currently widely used in industrial and energy systems and have strong equipment attributes. In household use, the soft water produced by water softeners usually has the effects of reducing scale in water heating equipment such as water heaters, wall-mounted boilers, electric water heaters, and bathrooms, avoiding pipe blockage, reducing the attenuation of heat exchange efficiency of heating equipment, reducing the use of detergents, being more friendly to human skin, and making clothes softer and brighter in color after washing.

[0050] like Figures 1 to 5 As shown, the utility model proposes a tank assembly. It should be noted that the tank assembly provided by the utility model is used in a water softening device. The tank assembly is filled with resin. The water distributor 200 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 ion exchange in the water. At the same time, the water distributor 200 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 200 can also serve as a supporting layer to prevent the resin particles from moving due to the impact of the water flow and maintain the stability and effective working volume of the resin layer.

[0051] Specifically, Figures 1 to 3As shown, the tank assembly includes a barrel 100, a water distributor 200 and a central tube 300. A limiting tube 110 is provided in the barrel 100, and the limiting tube 110 is connected to the waterway component. The water distributor 200 is arranged in the barrel 100, and the peripheral wall of the water distributor 200 abuts against the inner wall of the barrel 100 to radially limit the water distributor 200, so as to prevent the water distributor 200 from moving in the radial direction when the tank assembly is in use, thereby affecting the water distribution effect. A first limiting portion is provided on the water distributor 200, the central tube 300 is penetrated in the water distributor 200, and the end of the central tube 300 is plugged with the limiting tube 110, and the outer peripheral wall of the central tube 300 is provided with a second limiting portion, and the first limiting portion is limited and matched with the second limiting portion, so as to limit the axial displacement of the water distributor 200, so as to prevent the water distributor 200 from moving in the axial direction when the tank assembly is in use, thereby affecting the water distribution effect.

[0052] In this way, the setting of the limit part simplifies the assembly process of the tank assembly, reduces the complexity of the assembly and maintenance of the tank assembly, and reduces the production and operation and maintenance costs. In addition, the radial and axial limit design of the water distributor 200 enhances the mechanical strength and durability of the tank assembly, and improves the reliability and service life of the tank assembly. Since the position of the water distributor 200 is stable, the mechanical impact and water flow scouring of the resin layer can be reduced, the service life of the resin can be extended, and the ion exchange performance can be improved.

[0053] According to the tank assembly of the embodiment of the utility model, by arranging the limiting tube 110 in the tank body, the central tube 300 can be plugged and matched with the limiting tube 110. By arranging the first limiting part on the water distributor 200 and the second limiting part on the outer peripheral wall of the central tube 300, the first limiting part and the second limiting part cooperate to axially limit the water distributor 200, so as to prevent the water distributor 200 from moving in the axial direction when the tank assembly is in use, thereby affecting the water distribution effect.

[0054] like Figure 3 As shown, in one embodiment of the present invention, a matching portion is provided on the peripheral wall of the water distributor 200, and the matching portion is interference-fitted with the inner wall of the barrel body 100. In this way, the positioning accuracy of the water distributor 200 on the barrel body 100 can be improved, and the vibration resistance of the water distributor 200 can be improved. This ensures that the water distributor 200 can remain in a fixed position during the operation of the soft water device, and will not shift even under the influence of water flow pressure or mechanical vibration.

[0055] In addition, since the matching part and the inner wall of the barrel body 100 can be directly interference-fitted, additional fixings such as screws or adhesives can be reduced when installing the water distributor 200, thereby simplifying the assembly process of the water distributor 200 and improving the assembly efficiency. Moreover, the interference fit between the matching part and the barrel body 100 can form a tight interface between the water distributor 200 and the barrel body 100, which can effectively prevent water leakage, thereby ensuring that water only flows through a predetermined path, optimizing water flow distribution, and improving soft water treatment efficiency. Due to the stability of the position of the water distributor 200, it can be ensured that the water flows evenly through the water distributor 200 and effectively contacts the resin layer, which can ensure the uniformity and effectiveness of ion exchange during the water treatment process.

[0056] like Figure 3 As shown, in one embodiment of the utility model, the peripheral wall of the water distributor 200 is provided with a first sealing groove 210, and the matching part is a first sealing ring 211 provided in the first sealing groove 210, and the first sealing ring 211 abuts against the inner wall of the barrel body 100. In this way, the sealing between the water distributor 200 and the barrel body 100 can be increased, and the resin can be prevented from leaking to the outside of the water distributor 200, thereby improving the accuracy and efficiency of water treatment. In addition, the provision of the sealing ring can also prevent sediments, particles or other impurities that may be brought in with the water flow from entering the interior of the tank assembly, thereby providing additional protection for the water distributor 200 and the resin layer. Among them, the first sealing ring 211 can be made of silicone or other rubber sealing materials through double-material injection molding and integrated with the water distributor 200 to achieve sealing and prevent resin leakage.

[0057] like Figure 3 As shown, in one embodiment of the present invention, the matching portion is a matching boss 220 provided on the peripheral wall of the water distributor 200, and the matching boss 220 is interference fit with the inner wall of the barrel body 100, thereby improving the positioning accuracy of the water distributor 200 on the barrel body 100. In addition, when the water distributor 200 is installed on the barrel body 100, a stable interference fit can be achieved by simply pressing or tapping, which simplifies the installation process.

[0058] like Figure 3 As shown, in one embodiment of the present invention, a step 120 is provided on the inner wall of the barrel body 100, and the matching portion can abut against the step 120. In this way, the water distributor 200 can be accurately positioned inside the barrel body 100, thereby ensuring the consistency of the water distribution effect. The step 120 forms a fixed support surface on the inner wall of the barrel body 100, which can effectively support the water distributor 200 and reduce the displacement of the water distributor 200 caused by vibration or external force.

[0059] like Figure 5As shown, in one embodiment of the utility model, the matching part is an elastic rib 230, one end of the elastic rib 230 is connected to the water distributor 200, and the other end extends toward and abuts against the inner wall of the barrel body 100, so that the elastic rib 230 and the inner wall of the barrel body 100 have an interference fit. When the water distributor 200 is pushed upward from the bottom to the top of the central tube 300, the elastic rib 230 will be deformed due to the interference fit with the inner wall of the barrel body 100. At this time, since the elastic rib 230 has a certain elasticity, it will be subjected to the pressure of the inner wall of the barrel body 100, thereby generating an inward elastic deformation.

[0060] Since there is a certain amount of interference between the elastic rib 230 and the inner wall of the barrel body 100, the elastic rib 230 will exert a reaction force in the opposite direction on the inner wall of the barrel body 100 when it is deformed. In this way, a state of mutual compression is formed between the elastic rib 230 and the inner wall of the barrel body 100, so that the water distributor 200 is more firmly positioned inside the barrel body 100.

[0061] When the water distributor 200 reaches the predetermined position, due to the elastic restoring force generated by the deformation of the elastic rib 230, it will continue to exert an outward force, so that a stable static friction force is formed between the water distributor 200 and the inner wall of the barrel body 100, thereby maintaining the axial and radial positions of the water distributor 200 during use, and avoiding displacement due to water flow or other external factors. In this way, even under conditions such as pressure changes, temperature fluctuations or mechanical vibrations, the position of the water distributor 200 can remain stable, ensuring the normal operation of the water softening equipment and effective water treatment performance.

[0062] like Figure 2 As shown, in one embodiment of the present invention, the second limiting portion is a limiting boss 310 provided on the outer peripheral wall of the central tube 300, the free end of the first limiting portion abuts against the limiting boss 310, and the free end of the limiting tube 110 is inserted between the first limiting portion and the outer wall of the central tube 300. In this way, the axial position stability of the water distributor 200 on the central tube 300 is ensured, and the water distributor 200 is prevented from being displaced in the axial direction under the impact of water flow or equipment vibration.

[0063] In addition, the matching design between the limiting boss 310 and the first limiting portion in the utility model can also improve the assembly efficiency of the water distributor 200 and the center pipe 300. Due to the mutual cooperation between the limiting boss 310 and the first limiting portion, the installer can easily identify whether the center pipe 300 has been installed in place, and when maintenance or replacement of the center pipe 300 is required, it can also be quickly and accurately disassembled and reinstalled.

[0064] like Figure 2As shown, in one embodiment of the utility model, the limiting boss 310 is an annular boss provided on the outer peripheral wall of the central tube 300. In this way, when the central tube 300 is inserted into the water distributor 200, the annular boss can cover the connection gap between the central tube 300 and the water distributor 200, and prevent the resin from leaking from the connection gap between the central tube 300 and the water distributor 200. Of course, the setting method of the limiting boss 310 is not limited to a single annular boss. In some other embodiments of the utility model, the limiting boss 310 can be multiple, and the multiple limiting bosses 310 are spaced apart along the peripheral direction of the central tube 300. This multi-point abutment structure enhances the stability of the central tube 300 when inserted into the water distributor 200, and provides sealing points at different positions, thereby further improving the sealing performance and durability of the component.

[0065] In addition, in some other embodiments of the present invention, the first limiting portion may also be an annular boss.

[0066] like Figure 2 As shown, in one embodiment of the present invention, the free end of the limiting tube 110 abuts against the limiting boss 310. Figure 2 As shown, the free end of the limit tube 110 is clamped between the gap between the central tube 300 and the water distributor 200, and abuts against the limit boss 310, so that the limit tube 110, the water distributor 200 and the central tube 300 can form a stable plug-in structure, and fix the water distributor 200 and the central tube 300 at the same time. Through this stable plug-in structure, the limit tube 110, the water distributor 200 and the central tube 300 can support each other, reducing the relative movement and friction between the water distributor 200 and the central tube 300 when the water flow impacts or the equipment vibrates, and improving the overall stability of the equipment. In addition, the abutment relationship between the limit tube 110 and the limit boss 310, as well as the clamping position of the limit tube 110, ensure the correct alignment of the water distributor 200 and the central tube 300 during the assembly process, thereby ensuring accurate assembly accuracy.

[0067] like Figure 4 and Figure 6As shown, in one embodiment of the utility model, the second limiting portion is a limiting groove 320 provided on the outer peripheral wall of the central tube 300, and the free end of the first limiting portion is clamped in the limiting groove 320. In this way, the water distributor 200 is fixed at a specific axial position of the central tube 300 to prevent the water distributor 200 from sliding or shifting along the axial direction of the central tube 300 when the water softening device is running. Due to the clamping design, when the water distributor 200 is maintained or replaced, the staff can quickly release the clamping between the first limiting portion and the limiting groove 320, which is convenient for disassembling and replacing the water distributor 200 or the related components of the central tube 300. In addition, the clamping structure can provide additional stability under mechanical vibration or water flow impact, prevent the water distributor 200 from shifting due to vibration, and ensure the normal operation of the water softening device. The use of the clamping design can reduce the need for additional fixing components, such as screws or welding points, reduce production costs, and reduce possible failure points.

[0068] like Figure 4 and Figure 6 As shown, in one embodiment of the utility model, the first limiting portion is an elastic claw 240. When the water distributor 200 is pushed from bottom to top to the top of the central tube 300, the elastic claw 240 is inserted into the limiting groove 320 to achieve axial limiting of the water distributor 200 on the central tube 300.

[0069] Among them, the elastic claw 240 abuts against the limiting groove 320 through elastic deformation. When the water distributor 200 is pushed toward the top of the central tube 300, the elastic claw 240 first contacts the opening part of the limiting groove 320, and the elastic claw 240 can adapt to the position and shape of the limiting groove 320. As the water distributor 200 continues to be pushed up, the elastic claw 240 further aligns with the limiting groove 320 and begins to enter the limiting groove 320. The elasticity of the claw allows it to be compressed or slightly deformed when it contacts the edge of the limiting groove 320. When the elastic claw 240 completely enters the limiting groove 320, it will expand or restore its original shape in the limiting groove 320, and the elastic claw 240 will generate outward tension inside the limiting groove 320 to form a stable locking state. The expansion of the elastic claw 240 in the limiting groove 320 fixes the water distributor 200 at the accurate position on the top of the central pipe 300, preventing the water distributor 200 from axial movement under the action of water pressure or mechanical vibration.

[0070] like Figure 2As shown, in one embodiment of the present invention, the end of the central tube 300 is inserted into the limiting tube 110, and a second sealing ring 331 is provided between the inner wall of the limiting tube 110 and the outer wall of the central tube 300. The second sealing ring 331 is located at the contact interface between the limiting tube 110 and the central tube 300, which can prevent water flow, impurities or resin and other substances from leaking or penetrating through the joint between the limiting tube 110 and the central tube 300, thereby improving the sealing between the limiting tube 110 and the central tube 300. Among them, the second sealing ring 331 can be made of silicone or other rubber sealing materials through double injection molding and integrated with the central tube 300 to achieve sealing and prevent resin leakage.

[0071] like Figure 2 As shown, in one embodiment of the present invention, a second sealing groove 330 is provided on at least one of the inner wall of the limiting tube 110 and the outer wall of the central tube 300, and a second sealing ring 331 is provided in the second sealing groove 330. The second sealing groove 330 can make the second sealing ring 331 better withstand compression and deformation, thereby extending the service life of the second sealing ring 331.

[0072] like Figure 6 As shown, in one embodiment of the utility model, the peripheral surface of the water distributor 200 is a spherical surface 201, and part of the inner wall of the barrel body 100 is set to an arc surface with the spherical surface 201, and the spherical surface 201 abuts against the arc surface of the barrel body 100, so as to limit the axial direction of the water distributor 200 and prevent the water distributor 200 from moving in the axial direction, thereby affecting the water distribution performance. At the same time, the fitting position of the water distributor 200 and the barrel body 100 can also be sealed to prevent the resin from leaking from the fitting position of the water distributor 200 and the barrel body 100.

[0073] like Figure 7 As shown, in one embodiment of the utility model, the water distributor 200 includes a disc 10 and a filter (not shown in the figure). The disc 250 includes a plurality of vertical ribs 251 and a plurality of circular ribs 252, the plurality of circular ribs 252 are distributed in concentric circles, and a fan-shaped hole 255 is formed between the circular ribs 252 and the vertical ribs 251. In this way, when the water flows into the tank assembly, after passing through the fan-shaped holes 255 formed by the vertical ribs 251 and the circular ribs 252, the water flow is guided and dispersed to various areas inside the barrel 100, so that the water flow can be evenly distributed on the cross section of the barrel 100, which not only ensures that the water flow can fully contact the resin layer in the barrel 100, thereby maximizing the ion exchange efficiency of the resin, but also makes the flow velocity distribution of the water flow when passing through the resin layer more uniform, reducing the problem of uneven resin utilization or channel flow that may be caused by uneven water flow.

[0074] like Figure 8As shown, in one embodiment of the utility model, the disc 250 also includes a perforated plate 253, which is connected to both the circular ribs 252 and the vertical ribs 251. The perforated plate 253 is provided with a plurality of small holes 254. In the radially outward direction of the disc 250, the small holes 254 are arranged radially, and there is at least one small hole 254 in the area enclosed by any two adjacent vertical ribs 251 and two adjacent partial circular ribs 252. The small holes 254 on the perforated plate 253 can further disperse the water flow, so that the water flow is more evenly distributed inside the barrel 100, and the contact area between the water flow and the resin is increased, thereby improving the efficiency of ion exchange. At the same time, the setting of the small holes 254 can also prevent the resin particles from being moved by the impact of the water flow, and maintain the stability and effective working volume of the resin layer. In addition, the setting of the perforated plate 253 can also enhance the structural stability of the disc 250, improve the bearing capacity of the disc 250 itself, and prevent the disc 250 from being deformed under the impact of the water flow.

[0075] like Figure 8 As shown, in one embodiment of the present invention, a plurality of small holes 254 are arranged in concentric circles around the center of the disc body 250, so that the disc body 250 can further distribute water evenly. In addition, by adjusting the number and size of the small holes 254, the distribution of water can be adjusted, so that the water flow is more uniform over the entire cross section, further improving the water distribution effect in the regeneration state and increasing the water production.

[0076] The utility model also provides a water softening device, comprising the above tank assembly, a water channel component and a control valve. The water channel component is connected to the limit pipe 110 in the tank assembly, 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.
