[0046] 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.

[0047] like Figures 1 to 5 As shown, the utility model proposes a tank assembly 100, including a tank body 110, a water distributor 120 and a filter. It should be noted that the tank assembly 100 provided by the utility model is applied to a water softening device, and the tank assembly 100 is equipped with resin and a water distributor 120. The water distributor 120 can evenly distribute the incoming water flow in the tank assembly 100 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 120 also prevents the resin particles from flowing out of the tank body with the water, that is, ensures that the resin particles are retained in the tank while allowing the water flow to pass through. In addition, the water distributor 120 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.

[0048] Specifically, Figure 2 , Figure 3 and Figure 5 As shown, the tank body 110 includes a main body section 111 and an opening section 112 which are interconnected, wherein the main body section 111 is used to place a resin layer, and the resin layer is used to soften water. The opening section 112 includes a necking section 113 and a straight section 114, wherein one end of the necking section 113 is connected to the main body section 111, and one end of the straight section 114 is connected to the other end of the necking section 113, and the other end forms an opening 115.

[0049] The water distributor 120 is engaged with the straight section 114, the depth of the straight section 114 is less than the height of the water distributor 120, and the water distributor 120 includes a chassis 121 and a panel 122, the panel 122 is arranged around the outer periphery of the chassis 121, and the panel 122 and the chassis 121 both have a hollow portion 123. The filter screen is arranged on the water distributor 120, so that by adjusting the mesh difference between the filter screen of the chassis 121 and the filter screen of the panel 122, the resistance distribution of the water on the chassis 121 and the panel 122 can be adjusted, so that the water flow from the panel 122 and the chassis 121 and the water output can be adjusted. In addition, since the hollow portion 123 of the enclosure 122 can guide water to flow radially outward from the water distributor 120, by adjusting the resistance distribution, more water can flow into the tank body from the side and fill the outer circle area of ​​the tank body, so that the water flow can be evenly distributed on the cross-section of the tank body, allowing the water flow to fully contact the resin and increase the amount of soft water.

[0050] The filter can also prevent the resin particles from penetrating the filter while allowing the broken and finer resin residues to be discharged. In this way, the resin particles can be protected from being carried out of the tank assembly 100 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.

[0051] According to the tank assembly 100 of the embodiment of the utility model, hollow holes are set on the enclosure 122 and the chassis 121, and the filter screen is covered on the enclosure 122 and the chassis 121. In this way, by adjusting the difference in the mesh number of the filter screen of the chassis 121 and the enclosure 122, the resistance distribution of water on the chassis 121 and the enclosure 122 can be adjusted, so that the water flow from the enclosure 122 and the chassis 121 and the water output can be adjusted. In addition, since the hollow portion 123 of the enclosure 122 can guide the water to flow radially outward from the water distributor 120, by adjusting the resistance distribution, more water can flow into the tank from the side and fill the outer ring area of ​​the tank, so that the water flow can be evenly distributed on the cross section of the tank, so that the water flow can fully contact with the resin and increase the amount of soft water.

[0052] like Figure 3 As shown, in one embodiment of the present invention, the ratio of the diameter of the wide mouth of the constricted section 113 to the diameter of the water distributor 120 is 2:1. In this way, the larger wide mouth can better guide the fluid to be evenly distributed on the water distributor 120, thereby improving the uniformity of fluid distribution. In addition, the larger wide mouth diameter can also prevent larger particles or debris from blocking the constricted section 113, ensuring smooth water flow.

[0053] like Figure 1As shown, in one embodiment of the utility model, the tank assembly 100 also includes an impeller assembly 130, which is connected to the water distributor 120 and is rotatable relative to the water distributor 120. In this way, the impeller assembly 130 can optimize the resistance distribution of the water flow, thereby achieving fine-tuning of the water flow dynamics. The rotation of the impeller assembly 130 can effectively guide the water to the outer area of ​​the water distributor 120, enhance the inertia of the water flow, thereby promoting the tendency of the water flow to diffuse outward, and then adjust the water flow distribution in the tank to ensure sufficient contact between the water flow and the resin. The filter screen covers the water distributor 120.

[0054] like Figure 2 and Figure 3 As shown, in one embodiment of the utility model, the chassis 121 and the enclosure 122 define a receiving chamber 124, and the impeller assembly 130 is rotatably disposed in the receiving chamber 124. In this way, an appropriate gap is ensured between the impeller assembly 130 and the water distributor 120 to promote the circulation of water flow, and the probability of friction or collision between the impeller assembly 130 and the water distributor 120 during rotation is reduced, thereby improving the operating efficiency and durability of the entire water distributor 120. The rotation of the impeller assembly 130 in the receiving chamber 124 can affect the water flow passing through the water distributor 120. By adjusting the rotation speed and direction of the impeller assembly 130, the speed and direction of the water flow can be accurately controlled to achieve the desired water distribution effect.

[0055] like Figure 2 As shown, in one embodiment of the present invention, the chassis 121 includes an annular rib 1211 and a plurality of connecting ribs 1212. The annular rib 1211 is connected to the enclosure 122, providing structural support and defining the peripheral edge of the accommodating cavity 124. The plurality of connecting ribs 1212 are arranged along the radial direction of the annular rib 1211, and the hollow portion 123 is formed between any two adjacent connecting ribs 1212, and the impeller assembly 130 is connected to the connecting rib 1212.

[0056] The provision of the annular ribs 1211 and the connecting ribs 1212 enhances the anti-deformation capability and bearing capacity of the chassis 121, and can also reduce the overall weight of the chassis 121. In addition, the hollow portions 123 formed by the connecting ribs 1212 serve as multiple water flow guide channels, which can better control the direction of the water flow and optimize the distribution of the water flow under the chassis 121. In addition, the hollow portions 123 make the chassis 121 easier to clean and maintain, and maintain the operating efficiency of the water distributor 120.

[0057] like Figure 2As shown, in one embodiment of the present invention, the angles formed between any two adjacent connecting ribs 1212 are equal. In this way, the water flow can be more evenly distributed when passing through the hollow portion 123, thereby forming a stable and consistent water flow pattern in the action area of ​​the water distributor 120. In addition, the evenly distributed connecting ribs 1212 can provide a balanced support force, thereby enhancing the structural stability and durability of the entire chassis 121 and reducing deformation and damage caused by uneven load.

[0058] like Figure 2 As shown, in one embodiment of the utility model, the enclosure 122 includes an annular ring 1221, a plurality of support ribs 1222 are arranged at intervals on the annular ring 1221, the hollow portion 123 is formed between any two adjacent support ribs 1222, and at least one support rib 1222 is connected to the chassis 121, so that the structural strength between the enclosure 122 and the chassis 121 is enhanced, and the water flow can be further guided. In addition, the support ribs 1222 can also reduce the weight of the enclosure 122.

[0059] like Figure 2 As shown, in one embodiment of the utility model, the distance between any two adjacent support ribs 1222 is equal. Since the distance between the support ribs 1222 is equal, the size of the hollow portion 123 is also equal, which helps to achieve uniform distribution of water flow and ensure that the water flow can evenly cover the required coverage area when leaving the water distributor 120. In this way, the water flow can be more evenly distributed when passing through the hollow portion 123, thereby forming a smooth and consistent water flow pattern in the action area of ​​the water distributor 120. In addition, the support ribs 1222 with equal distances can provide balanced force distribution on the enclosure 122, avoiding structural deformation or stress concentration due to uneven force, enhancing the overall structural stability of the water distributor 120, and reducing deformation and damage caused by uneven load.

[0060] like Figure 3 As shown, the tank assembly 100 also includes a central tube 140, and the central tube 140 is inserted into the water distributor 120. The water distributor 120 is arranged at both ends of the central tube 140, and the central tube 140 is inserted into the impeller assembly 130, so that the impeller assembly 130 can rotate around the central tube 140. In this way, the central tube 140 can provide a fixed rotation center for the impeller assembly 130, ensure the stability of the impeller assembly 130 during the rotation process, thereby improving the operating efficiency and reliability of the impeller assembly 130. In addition, the central tube 140 provides support inside the impeller assembly 130, which can reduce the deformation and damage of the impeller assembly 130 caused by water flow impact or external forces.

[0061] like Figure 4 and Figure 5As shown, in one embodiment of the utility model, the tube wall of the central tube 140 is provided with a protrusion 141, and the protrusion 141 abuts against the water distributor 120 body, so that the water distributor 120 body can be axially limited to prevent the water distributor 120 body from moving in the axial direction.

[0062] Below through Figures 1 to 5 The working process of the tank assembly 100 provided by the utility model is described. It should be noted that the tank assembly 100 can be forward washed and backwashed. When the tank assembly 100 needs to be forward washed, that is, the tap water needs to be softened, the tap water enters the tank body 110 from the water distributor 120 and contacts the resin layer in the tank body 110. At this time, the hardness ions (such as calcium, magnesium, etc.) in the water undergo a replacement reaction with the sodium ions on the resin, thereby "softening" the water quality, that is, reducing the content of hardness ions in the water. The resin layer acts as an ion exchange medium, and through this process, it captures hardness ions and releases sodium ions, thereby achieving the purpose of softening the water quality. The water treated by the resin layer is then guided out of the tank from the central tube 140 and supplied to the user.

[0063] Backwashing refers to the process of regenerating and cleaning the resin layer by changing the direction of water flow. When the tank assembly 100 needs to be backwashed, the water flows from the central tube 140 to the bottom of the tank body 110, is distributed to the resin layer by the water distributor 120, and finally discharged from the tank body 110. During the backwashing process, high-concentration salt water, i.e., regeneration agent, is usually used to flow through the tank body 110. This process can replace the hardness ions accumulated in the resin layer, and the sodium ions in the regeneration agent reoccupy the exchange sites of the resin layer. At the same time, the backwash water flow can also take away solid particles and other sediments in the resin layer, clean the resin layer and restore its function of softening water quality.

[0064] In one embodiment of the utility model, the mesh number of the filter is 80-400 mesh. For example, the mesh number of the filter can be 300 mesh, so that the filter can block the resin particles while maintaining the smoothness of the water flow, avoiding water flow blockage or pressure loss caused by too small pores of the filter. During the operation of the water distributor 120, 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 of 80 to 400 mesh not only meets the requirements of operating efficiency, but also ensures the relatively low maintenance cost of the equipment.

[0065] The utility model also provides a water softening device, comprising the above tank assembly 100, a water channel component and a control valve. The water channel component is connected to the tank body 110 of the tank assembly 100, and the control valve is connected to the water channel component. The control valve is used to control the switching of the water channel in the water channel component.

[0066] The water softening device provided by the utility model includes the above-mentioned tank assembly 100, and thus also has the beneficial effects of the above-mentioned tank assembly 100, which will not be described in detail here.

[0067] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
