[0028] The specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and examples, so as to better understand the solution of this utility model and its advantages in various aspects. However, the specific embodiments and examples described below are for illustrative purposes only and are not intended to limit this utility model.

[0029] Figure 1 A resin tank 100 according to an embodiment of the present invention is shown. For example... Figure 1 As shown, the resin tank 100 includes a tank body 110, a tank cover 120, a central tube 130, and a water distributor 140.

[0030] Tank 110 includes an opening and an inner cavity bottom wall, such as Figure 2As shown, the inner cavity bottom wall of the tank 110 is provided with a flow guiding surface 111 and a flow diversion structure 112. In this embodiment, the flow guiding surface 111 is located at the center of the inner cavity bottom wall. The flow diversion structure 112 includes a flow diversion cone 112a located at the center of the flow guiding surface 111. The flow diversion cone 112a corresponds to the position of the central pipe 130 and is used to divert water flowing into or out of the central pipe 130. The flow diversion structure 112 also includes a first flow diversion plate 112b located around the flow diversion cone 112a. Figure 2 In the illustrated embodiment, there are four first flow dividers 112b, which are evenly arranged around the flow divider cone 112a. The flow divider structure 112 also includes a second flow divider 112c arranged around the flow guide surface 111. Figure 2 In the illustrated embodiment, the second diversion plate 112c has a stepped structure. The height of the portion of the second diversion plate 112c near the guide surface 111 is lower than the height of the portion away from the guide surface 111, and the height of the inner portion of the second diversion plate 112c is lower than the height of the outer portion. The arrangement of the guide surface 111 and the diversion structure 112 facilitates a more uniform distribution of water flow within the tank, preventing the existence of stagnant water zones.

[0031] The tank cover 120 is placed over the opening of the tank 110 and includes an inlet 121 and an outlet 122.

[0032] A central pipe 130 is disposed inside the tank 110 and connected to the outlet 122. In this embodiment, the central pipe 130 is disposed at the center of the tank 110. In other embodiments of this application, the central pipe 130 may be disposed anywhere within the tank 110.

[0033] The water distributor 140 includes an upper water distributor 141 and a lower water distributor 142. For example... Figure 3 As shown, the upper water distributor 141 and the lower water distributor 142 are respectively connected to both ends of the central tube 130. Among them, the upper water distributor 141 and the tank cover 120 form the upper water distribution cavity A, and the lower water distributor 142 and the inner bottom wall of the tank 110 form the lower water distribution cavity B.

[0034] The resin tank of this application has a flow guiding surface and a flow distribution structure on the bottom wall of its inner cavity, and a water distributor is also installed inside the resin tank, which can improve the uniformity of water distribution and thus improve the water treatment effect. Therefore, the height of the resin tank can be reduced while maintaining or even improving water production and water regeneration performance. Compared with the prior art, the height of the resin tank of this application can be reduced by 20%-30%, and the water distribution uniformity of the entire cross-section of the resin tank is greatly improved.

[0035] Optionally, the distance H1 between the lower water distributor 141 and the guide surface 111 is 3-6 mm. The channel between the lower water distributor 141 and the guide surface 111 acts as an acceleration channel in the water regeneration state, ensuring that the regenerated brine fully covers the entire cross-section of the resin tank. In the water production state, this channel acts as a deceleration channel, ensuring that the water fully contacts the resin in the resin tank. Therefore, to ensure more uniform water distribution, H1 should not be too large, but it also should not be too small.

[0036] Optionally, the height H2 of the upper water distribution chamber is 5-20mm. The height H2 is the distance from the tank cover 120 to the upper water distributor 141. The height space within the above range is conducive to the uniform distribution of water across the entire cross-section of the resin tank.

[0037] Optionally, the height H3 of the lower water distribution chamber is 5-15mm. The height H3 is the distance between the lower water distributor 142 and the bottom wall of the inner cavity of the tank 110. The outer side of the bottom wall of the inner cavity of the tank 110 is more concave than the middle area, which can serve as a release area and buffer area for regenerated brine and tap water.

[0038] Figure 3 In the illustrated embodiment, the upper water distributor 141 includes a first part 141a that mates with the central pipe 130 and a second part 141b that mates with the inner cavity of the tank 110. The lower water distributor 142 includes a third part 142a that mates with the central pipe 130 and a fourth part 142b that mates with the inner cavity of the tank 110. The second part 141b and the fourth part 142b each include an outer frame and a rib support, and a filter screen is provided on the plane formed by the outer frame and the rib support.

[0039] like Figure 3 As shown, the lower water distributor 142 is also provided with a flow guide baffle 142c. The flow guide baffle 142c works together with the flow guide surface 111 and the flow distribution structure 112 on the bottom wall of the inner cavity of the tank 110 to better facilitate the uniform distribution of water.

[0040] Optionally, the upper water distributor 141 and the lower water distributor 142 are flat water distributors.

[0041] like Figure 3 As shown, in this embodiment, the resin tank 100 also includes a water distributor 150, which is fitted onto the upper water distributor 141 at a position corresponding to the central pipe 130. The water distributor 150 allows water entering from the inlet 121 to flow as far as possible towards the edge of the upper water distributor 141, ensuring that the water fully contacts as much resin as possible, preventing stagnant water zones, and improving the water treatment effect.

[0042] The resin tank provided in this application has a resin filling rate of over 85%, meaning that the resin occupies over 85% of the internal volume of the entire tank, and the resin filling rate can reach over 92% in the space formed by the upper and lower water distributors and the tank.

[0043] Figure 4 This is a water circuit diagram for water production using the resin tank provided in this application. Figure 5 A water circuit diagram for water regeneration using the resin tank provided in this application.

[0044] like Figure 4 As shown, during water production, tap water enters the upper water distribution chamber A through the inlet 121, then passes through the water distribution plate and enters the inner cavity of the tank 110 through the upper water distributor 141 to contact the resin. Then, it enters the lower water distribution chamber B through the lower water distributor 142, then enters the central pipe 130, and finally flows out of the resin tank 100 through the outlet 122.

[0045] The water circuit during regeneration is the reverse of the water circuit during water production, such as... Figure 5 As shown, brine enters the central pipe 130 from the outlet 122, then enters the lower water distribution chamber B, and then is distributed by the guide surface 111 and the diversion structure 112 on the bottom wall of the inner cavity of the tank 110. After that, it enters the inner cavity of the tank 110 through the lower water distributor 142 and comes into contact with the resin. Then it enters the upper water distribution chamber A through the upper water distributor 141, and finally flows out of the resin tank 100 from the inlet 121.

[0046] This application further provides a water softening device, including any of the resin tanks described above. The water softening effect of the water softening device provided by this application is excellent.

[0047] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
