[0040] A water softener is a device that uses cation exchange resin to remove calcium and magnesium ions from 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 a water softener 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.

[0041] In the relevant technical field, soft water resin tanks usually adopt a threaded connection reduction design, but the water distributor is a post-installation component, and the tank body cannot be inserted into the tank before or during production. Therefore, the upper and lower water distributors can only be smaller than the upper connection port, which is not conducive to improving the water distribution effect and reduces the resin regeneration rate and water production.

[0042] The utility model provides a resin tank component and a water softening device.

[0043] In the embodiment of the present utility model, Figures 1 to 4 As shown, the first tank body 100 is arranged in a cylindrical shape, and a first installation opening 120 is provided at one end of the first tank body 100, and a first connecting portion 130 is provided on the peripheral side of the first installation opening 120; the second tank body 200 has a first end 210 and a second end 220 arranged opposite to each other, and the first end 210 is connected to the first installation opening 120 to form a accommodating cavity 110 between the first tank body 100 and the second tank body 200, and the accommodating cavity 110 is communicated with the first installation opening 120, and the outer peripheral wall of the first end 210 is provided with a second connecting portion 211 corresponding to the first connecting portion 130, and a constriction 221 is provided on the end surface of the second end 220, and the constriction 221 is used to connect the accommodating cavity 110 with the water channel component 20; the water distribution mechanism 300 is installed in the accommodating cavity 110.

[0044] The resin tank assembly 10 includes a first tank body 100, a second tank body 200 and a water distribution mechanism 300. The first tank body 100 has a accommodating cavity 110 for accommodating resin and a first installation opening 120 connected to the accommodating cavity 110, and a first connecting portion 130 is provided on the peripheral side of the first installation opening 120; the second tank body 200 has a first end 210 and a second end 220 that are relatively arranged, the first end 210 is covered at the first installation opening 120, and the outer peripheral wall of the first end 210 is provided with a second connecting portion 211 corresponding to the first connecting portion 130, and a constriction 221 is provided on the end surface of the second end 220, and the constriction 221 is used to connect the accommodating cavity 110 with the water channel component 20; at least part of the water distribution mechanism 300 is installed in the accommodating cavity 110 through the first installation opening 120.

[0045] The resin tank assembly 10 includes a first tank body 100 and a second tank body 200. It is understood that the accommodating chamber 110 can be separately provided on the first tank body 100, or the accommodating chamber 110 is composed of the inner cavity of the first tank body 100 and the inner cavity of the second tank body 200, which is not specifically limited here. The accommodating chamber 110 is the main part of the resin tank assembly 10 and is used to store resin. According to application requirements, the design of the accommodating chamber 110 can have different shapes and sizes to adapt to different resin volumes and performance requirements, which is not specifically limited here.

[0046] This application is explained by taking the accommodation cavity 110 being arranged in the first tank body 100 as an example. Other embodiments can be implemented with reference to this embodiment. The first tank body 100 is roughly arranged in a cylindrical shape with one end open. The opening is the first installation opening 120. The first installation opening 120 can be used for docking and communicating with the second tank body 200. At the same time, it can be convenient to install the first tank body 100 and the second tank body 200, and pre-install the water distribution mechanism 300 in the installation cavity from the first installation. A first connecting portion 130 is arranged on the peripheral side around the first installation opening 120. The function of the first connecting portion 130 is to achieve a sealed connection between the first tank body 100 and the second tank body 200.

[0047] The second tank body 200 has a first end 210 and a second end 220 that are arranged opposite to each other. Specifically, the first end 210 is provided with a second installation opening that is connected to the first installation opening 120, and the constriction 221 is provided on the end face of the second tank body 200 away from the end of the first tank body 100. The constriction 221 is used to allow and control the fluid to flow into and out of the accommodating cavity 110. The size and shape of the constriction 221 can be adjusted according to actual needs to optimize the flow properties of the resin. A second connecting portion 211 corresponding to the first connecting portion 130 is also provided on the outer peripheral wall of the first end 210. The function of the first connecting portion 130 is to achieve a sealed connection between the second tank body 200 and the tank body. Among them, the first connecting portion 130 and the second connecting portion 211 can be assembled and connected by welding, clamping or threaded connection, etc., and no special limitation is made here.

[0048] The water distribution mechanism 300 is used to distribute the raw water evenly to the resin bed when the water flows into the resin tank, so that the raw water can flow evenly through the resin bed, so that the resin bed can fully contact and remove the hardness ions in the water. The size of the water distribution area of ​​the water distribution mechanism 300 in the accommodating chamber 110 will affect the water distribution effect, and further affect the regeneration rate and water production of the resin.

[0049] In the present application, by separating the resin tank into a first tank body 100 and a second tank body 200, a part of the water distributor mechanism 300 can be placed into the accommodating cavity 110 through the first installation opening 120 before the first tank body 100 and the second tank body 200 are assembled, so that the size of the water distribution mechanism 300 is not limited by the size of the constriction 221, and the water distribution area of ​​the water distribution mechanism 300 can cover the entire cross-sectional area of ​​the accommodating cavity 110, so that the water distribution effect during the regeneration process of the resin tank assembly 10 is significantly improved, thereby increasing the resin regeneration rate and water production.

[0050] Reference Figure 2 and Figure 4According to one embodiment of the utility model, the water distribution mechanism 300 includes an upper water distributor 310 and a lower water distributor 320, the upper water distributor 310 is arranged at the constriction 221, and the lower water distributor 320 is installed at the bottom of the first tank body 100 through the first installation opening 120. It can be understood that the design of the water distribution mechanism 300 can achieve uniform distribution and discharge of water. The upper water distributor 310 is located at the constriction 221, and when the water flow enters the water softener, the water is evenly distributed to the resin bed through the upper water distributor 310. In this way, the water can flow evenly in the resin bed, thereby achieving more effective softening treatment. The lower water distributor 320 is located at the bottom of the first tank body 100, and it is connected to the first tank body 100 through the first installation opening 120. The function of the lower water distributor 320 is to filter the treated water. After being treated by the resin bed, the water will be collected at the bottom of the first tank body 100, and then discharged from the resin tank assembly 10 through other components. In this embodiment, uniform distribution is achieved through the upper water distributor 310, and drainage is achieved through the lower water distributor 320, so that the water softener can continuously provide high-quality softened water. It should be noted that the lower water distributor 320 can be installed in the accommodating cavity 110 through the first installation opening 120, and the upper water distributor 310 can also be installed by opening a second installation opening on the first end 210, so that the upper water distributor 310 is not affected by the size of the shrinkage 221, so that the upper water distributor 310 can be adjusted in size as needed to improve the water distribution effect.

[0051] Reference Figure 2 and Figure 4 According to one embodiment of the utility model, the water distribution mechanism 300 also includes a central tube 330, one end of which extends from the constriction 221 into the accommodating chamber 110 along the axial direction of the resin tank, and the central tube 330 is connected to the upper water distributor 310 and the second water distributor through a through-hole. It can be understood that in this embodiment, the function of the central tube 330 is to guide the soft water after softening and filtration in the lower water distributor 320 out of the resin tank assembly 10, or to add salt water through the central tube 330 to flush the resin material located between the upper water distributor 310 and the lower water distributor 320, so that the resin material can be recycled and reused to increase the water production. The central tube 330 is arranged through the axial arrangement of the upper water distributor 310 and the lower water distributor 320, so as to simplify the soft water flow path and improve the soft water efficiency.

[0052] Reference Figures 2 to 6According to an embodiment of the utility model, the upper water distributor 310 includes a water distributor 311 and an impeller 312. The water distributor 311 is clamped with the constriction 221. The water distributor 311 has a diversion chamber and a water inlet 311a connected to the diversion chamber. The water inlet 311a is opposite to the constriction 221. The diversion chamber extends toward one side of the accommodating chamber 110. The central tube 330 passes through the water distributor 311 and is connected to the waterway component 20. The impeller 312 is arranged in the diversion chamber, and the impeller 312 is rotatably sleeved on the outer side of the central tube 330. It can be understood that the water distributor 311 is the main part of the upper water distributor 310. It is clamped with the constriction 221 to ensure that water can enter the water distributor 311. The water distributor 311 has a diversion chamber, which is used to guide water from the water inlet 311a into the water distributor 311 and evenly distribute it to the resin bed. The diversion cavity is extended toward one side of the accommodating cavity 110, so that water can flow along the circumference of the diversion cavity. The central tube 330 passes through the water distribution cylinder 311 and is connected to the water channel component 20, and the central tube 330 is axially abutted against the water distribution cylinder 311, which can play a certain role in supporting and fixing the water distribution cylinder 311. The impeller 312 is located in the diversion cavity, and the impeller 312 rotates by the impact of the water flow, and the raw water in the diversion cavity is dispersed by the rotation, thereby further improving the uniform distribution of the raw water.

[0053] Reference Figure 4 and Figure 5 According to an embodiment of the present invention, the impeller 312 includes an axial sleeve 312a and a plurality of blades 312b. The axial sleeve 312a is sleeved with the central tube 330, and the blades 312b have a hollow portion 312c. The plurality of blades 312b are evenly arranged around the axial sleeve 312a. It can be understood that the axial sleeve 312a is the main supporting part of the impeller 312, and is sleeved with the central tube 330 to ensure that the impeller 312 can rotate. The blades 312b are fixed on the axial sleeve 312a, and a plurality of blades 312b are evenly arranged around the axial sleeve 312a, and the intervals are equal, so that water can be evenly pushed and distributed when passing through the blades 312b. The blades 312b have a hollow portion 312c, which can reduce the weight of the blades 312b, making it easier for the impeller 312 to rotate, and also facilitate the flow and distribution of water when passing through the impeller 312.

[0054] Reference Figure 2According to an embodiment of the utility model, the first connecting portion 130 is provided with an external thread, the second connecting portion 211 is provided with an internal thread, and the first tank body 100 and the second tank body 200 are screwed together by the internal thread and the external thread. It can be understood that the external thread refers to a thread structure located on the outer surface of the first connecting portion 130, and its shape and size enable it to match the internal thread. The internal thread refers to a thread structure located inside the second connecting portion 211, and its shape and size correspond to the external thread. Through the screw connection, that is, the external thread on the first connecting portion 130 and the internal thread on the second connecting portion 211 are rotated and tightened, so that the connection between the first tank body 100 and the second tank body 200 can be ensured to be tight and stable. In this way, the screw connection method through the internal thread and the external thread has the characteristics of simplicity and reliability, can effectively connect the first tank body 100 and the second tank body 200, and is easy to disassemble and repair.

[0055] According to an embodiment of the utility model, the first connection part 130 and the second connection part 211 are welded to seal the first tank body 100 and the second tank body 200. In this embodiment, the first connection part 130 and the second connection part 211 are welded to firmly connect the first tank body 100 and the second tank body 200. Welding can achieve a sealed connection and effectively prevent the leakage of liquid, gas or other substances. When the welding is completed, the weld forms a continuous, seamless connection, ensuring the integrity and sealing of the connection part.

[0056] Reference Figure 4 According to an embodiment of the utility model, a plug-in column 140 is extended from the outer periphery of the first mounting opening 120 toward the second tank body 200, and a second mounting port 212 is provided on the end of the first end 210, and the plug-in column 140 and the second mounting port 212 are movably plugged in. In this embodiment, the connectivity between the first tank body 100 and the second tank body 200 is enhanced through the cooperation of the plug-in column 140 and the plug interface. At the same time, it is also convenient for the pre-assembly between the first tank body 100 and the second tank body 200, and for the alignment of the clamping or welding, thereby improving the installation efficiency. In addition, the matching design of the plug-in column 140 and the plug interface makes the connection part more stable, reduces the risk of loosening or falling off that may occur during use, and improves the stability of the overall structure. At the same time, the movably plug-in setting of the plug-in column 140 and the plug interface makes the assembly and disassembly process simple and quick.

[0057] Reference Figure 4According to an embodiment of the utility model, an annular sealing groove 141 is provided on the peripheral wall of the plug-in column 140, and the sealing member is sleeved in the annular sealing groove 141, and the sealing member abuts between the groove wall of the annular sealing groove 141 and the inner wall of the second mounting port 212. This embodiment greatly enhances the sealing performance of the connection part by providing the annular sealing groove 141 on the peripheral wall of the plug-in column 140 and using the sealing member for interference fit. The leakage of the fluid at the connection part is effectively avoided, and the normal use of the resin tank assembly 10 is ensured. The sealing member is installed in a sleeve-type manner, which facilitates the user's maintenance and replacement of the sealing member. When the sealing member is worn or damaged, the user can easily remove it and replace it with a new sealing member, thereby extending the service life of the resin tank assembly 10. The interference fit design ensures a tight fit between the sealing member and the plug-in column 140 and the plug-in port, reducing the loosening or displacement that may occur during use. By providing the annular sealing groove 141 and the sealing member on the plug-in column 140 , the use of the traditional fixing method and the connecting member is avoided, thus simplifying the overall structure and design.

[0058] In one embodiment, the resin tank assembly 10 further includes a water channel member 20, and a communication port is provided on the water channel member 20, so that the water flow can be conducted and distributed through the water channel member 20. In the present application, the communication port is used to connect with the constriction 221 of the second tank body 200. The shape and size of the communication port should match the constriction 221 to ensure a tight connection between the two. The second tank body 200 is provided with a first clamping portion on the peripheral side of the constriction 221, and a second clamping portion corresponding to the first clamping portion is provided on the peripheral side of the communication port, and the second clamping portion matches the first clamping portion on the second tank body 200. Through the rotary clamping connection between the first clamping portion and the second clamping portion, the water channel member 20 can be firmly connected to the second tank body 200. This connection method can provide better stability and reliability, ensuring that the water channel member 20 will not loosen or fall off during use. The present application is connected by a rotary clamping connection between the first clamping portion and the second clamping portion, which can be put in place by rotating at a small angle, which is simple and fast, and can effectively reduce installation time and workload. At the same time, the twist-on connection can also provide better stability, ensuring that the connection between the water channel component 20 and the second tank body 200 is firm and reliable.
