[0039] 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.

[0040] In the related technical field, the waterway plate is connected between the resin tank and the water softener to realize the waterway integration of the water softener; the central tube is connected between the resin tank and the waterway plate to realize the output of the soft water softened by the resin tank. The existing connection structure between the waterway plate and the central tube is complicated and easily forms a flow limit on the central tube, affecting the soft water output efficiency of the water softener.

[0041] The invention provides a resin tank assembly and a water softening device.

[0042] In the embodiment of the present invention, Figures 1 to 4 As shown, the resin tank assembly includes a tank body, a waterway plate, a center tube and an adapter, wherein the tank body has a accommodating cavity and a tank mouth connected to the accommodating cavity; the waterway plate is installed at one end of the tank body close to the tank mouth, and the waterway plate has a soft water channel and an adapter seat connected to the soft water channel; the center tube is arranged in the accommodating cavity, and the first end of the center tube passes through the tank mouth; the adapter is connected between the first end of the center tube and the adapter seat, and a water guide chamber connecting the soft water channel and the center tube is enclosed between the adapter and the adapter seat.

[0043] The tank body 100 is generally in the shape of a hollow cylinder, and a receiving cavity 110 is formed inside the tank body 100, wherein the receiving cavity 110 is the main part of the tank body 100 and is used to store the resin. The receiving cavity 110 can be designed in different shapes and sizes according to application requirements to adapt to different resin volumes and performance requirements, which are not particularly limited here.

[0044] A tank opening 120 is provided on an end surface of one end of the tank body 100, and the tank opening 120 is used to allow and control the fluid to flow into and out of the accommodating cavity 110. The size and shape of the tank opening 120 can be adjusted according to actual needs to optimize the flow properties of the resin.

[0045] The waterway component 200 is installed at one end of the tank body 100 near the tank opening 120 and has a soft water channel 210. The soft water channel 210 can guide the direction of the water flow, so that the soft water softened by the resin can be exported from the tank body 100 for users to use. Among them, a transfer seat 220 is provided at the docking position between the waterway component 200 and the tank opening 120. One end of the transfer seat 220 facing the tank opening 120 is designed as a communication port 221 for docking with the central pipe 300.

[0046] The central pipe 300 is located in the accommodation cavity 110. The first end of the central pipe 300 passes through the tank opening 120. The second end of the central pipe 300 is arranged at the bottom of the accommodation cavity 110 of the tank body 100. The central pipe 300 is mainly used as a channel for soft water diversion in the tank body 100.

[0047] The adapter 400 is connected to the first end of the central pipe 300 and covers the communication port 221 of the transfer seat 220 to form a water guiding chamber 410. The water guiding chamber 410 connects the central pipe 300 and the soft water channel 210 to ensure the smooth flow of water. It simplifies the connection between the waterway component 200 and the central pipe 300, makes the alignment more convenient, and improves the installation efficiency. In addition, it can also reduce the resistance of the water flow and improve the filtration efficiency.

[0048] In this application, a transfer seat 220 is provided at the connection between the waterway plate and the central pipe 300, and the adapter 400 is provided at the first end of the central pipe 300. A water guiding chamber 410 is formed between the transfer seat 220 and the adapter 400. The water guiding chamber 410 communicates with the central pipe 300 and the soft water flow path. In this way, by setting the water guiding chamber 410, the maximum flow rate at the connection between the central pipe 300 and the soft water flow path is increased, and the flow restriction caused by the inconsistent connection structure and flow path at the connection between the central pipe 300 and the soft water flow channel is reduced, effectively improving the soft water output efficiency of the soft water device.

[0049] According to an embodiment of the present invention, the flow rate of the communication gap 211 is greater than or equal to the flow rate of the water guiding chamber 410. In this embodiment, the flow rate of the communication gap 211 is set to be greater than or equal to the flow rate of the water guiding chamber 410 because the water guiding chamber 410 is the main water flow channel for softened water in the resin tank assembly 10. The softened water chamber is connected to the softened water channel 210 and the central pipe 300, and is responsible for introducing or discharging water flow into or out of the resin layer. If the flow rate of the communication gap 211 is less than the flow rate of the water guiding chamber 410, it will cause poor water flow and even accumulation. This will not only affect the softening effect, but may also lead to insufficient impact force of the water flow on the resin layer, affecting the adsorption effect of the resin layer. In order to make the flow rate of the communication gap 211 greater than or equal to the flow rate of the water guiding chamber 410, precise design and calculation of the communication gap 211 are required. This requires considering multiple factors, such as the speed, flow rate, pressure of the water flow, as well as the thickness and adsorption performance of the resin layer, etc. Through precise calculation and design, it can be ensured that the size and shape of the communication gap 211 can meet the requirements of the water guiding chamber 410, thus achieving the best water flow effect. The flow rate of the communication gap 211 being greater than or equal to the flow rate of the water guiding chamber 410 enables the communication gap 211 to meet the water flow requirements of the water guiding chamber 410. If the flow rate of the communication gap 211 is too small, it may cause water accumulation in the water guiding chamber 410, thus affecting the filtration effect. By ensuring that the flow rate of the communication gap 211 is greater than or equal to the flow rate of the water guiding chamber 410, this accumulation phenomenon can be avoided, improving the filtration efficiency. At the same time, since the flow rate of the communication gap 211 is optimized, the water flow can be more uniform and stable when output from the resin tank. The filtration effect can be improved, and the quality and output of the softened water can be ensured. At the same time, due to better control of the water flow, the energy consumption can be reduced, and the overall performance of the resin tank assembly 10 can be improved.

[0050] Refer to Figure 4, according to an embodiment of the present invention, the water guiding chamber 410 extends in the circumferential direction of the tank body 100 from the tank opening 120. The outer wall of the adapter base 220 extends from one side of the water path member 200 towards the tank body 100 and encloses a water guiding groove 223. It can be understood that the water guiding chamber 410 is used to connect the central tube 300 extending from the tank opening 120 and the soft water passage 210 provided in the water path member 200. Among them, the central axis of the water guiding chamber 410 and the central axis of the soft water passage 210 can be arranged at an angle to each other. In this way, it can be set according to specific needs, such as being perpendicular to each other, forming an acute angle or an obtuse angle with each other. The outer wall of the adapter base 220 extends from one side of the water path member 200 towards the tank body 100 to form a water guiding groove 223. One end surface of the export groove facing the resin tank is the communication port 221. The adapter 400 is covered on the communication port 221 to form a water guiding chamber 410 between the adapter base 220 and the adapter 400. In this way, the installation process is simplified and the installation efficiency is improved. At the same time, the design of the water guiding chamber 410 can reduce the restriction of the docking structure on the water flow, ensure that the water flows smoothly through the soft water passage 210 entering the water path member 200, and improve the soft water output rate.

[0051] Referring to Figure 4 , according to an embodiment of the present invention, one end of the adapter base 220 facing the circumferential direction intersects with a part of the soft water passage 210. A communication notch 211 is provided on one side of the soft water passage 210 corresponding to the adapter base 220. The communication notch 211 is used to connect the soft water passage 210 and the water guiding chamber 410. It can be understood that by setting the connection notch, the flow rate at the communication port between the soft water passage 210 and the adapter base 220 can be increased, preventing water from accumulating in the water guiding chamber 410 and improving the soft water output efficiency.

[0052] In one embodiment, the cross-sectional area of the water guiding chamber 410 for flowing through is greater than or equal to the cross-sectional area of the central tube 300. It can be understood that the cross-sectional area of the water guiding chamber 410 for flowing through being greater than or equal to the cross-sectional area of the central tube 300 can ensure that there will be no problems of flow limiting or excessive resistance when the water flows through the water guiding chamber 410. It can effectively guarantee the soft water output efficiency. In addition, it can also reduce the resistance of the water flow, reduce energy consumption, and improve the overall performance of the resin tank assembly 10. By optimizing the design of the water guiding chamber 410 and the central tube 300, the water flow can be better controlled, making it flow more evenly and stably through the resin layer, thereby obtaining a better filtering effect.

[0053] Referring to Figure 3, according to an embodiment of the present invention, an annular abutting step 222 is provided on the inner wall of the communication port 221, and an abutting flange 420 extends from the outer peripheral edge of the adapter 400 toward the adapter seat 220, and the abutting step and the abutting flange 420 are in abutting cooperation. It can be understood that an annular abutting step 222 is provided on the inner wall of the communication port 221 to cooperate with the abutting flange 420 extending from the outer peripheral edge of the adapter 400 toward the adapter seat 220. It can ensure the tight connection between the adapter 400 and the adapter seat 220, prevent water from leaking from the connection, and thus improve the filtration effect and use safety. The design of the annular abutting step 222 can increase the contact area between the adapter 400 and the inner wall of the communication port 221 and improve the connection stability. At the same time, the abutting cooperation between the abutting flange 420 and the abutting step can form a closed water guiding chamber 410 to ensure that the water flow can smoothly flow through the resin layer. And, since the connection between the adapter 400 and the communication port 221 is realized by the abutting cooperation of the abutting step and the abutting flange 420, additional fixing or fastening measures may not be required, further improving the alignment accuracy of the adapter 400 and the adapter seat 220 and facilitating the alignment installation.

[0054] Refer to Figure 3 , according to an embodiment of the present invention, a sealing groove 430 is provided on the outer peripheral wall of the adapter 400, and the resin tank assembly 10 further includes a sealing member, the sealing member is sleeved in the sealing groove 430, and the sealing member abuts between the groove wall of the sealing groove 430 and the inner wall of the communication port 221. It can be understood that a sealing groove 430 is provided on the outer peripheral wall of the adapter 400. The sealing groove 430 is used to accommodate the sealing member to achieve the sealing connection between the adapter 400 and the communication port 221. The design of the sealing groove 430 can ensure that the sealing member can be firmly positioned in the sealing groove 430. The sealing member abuts between the groove wall of the sealing groove 430 and the inner wall of the communication port 221. It can ensure that the sealing member forms an effective sealing layer between the adapter 400 and the communication port 221 to prevent water or other liquids from leaking. Improve the sealing performance between the adapter 400 and the adapter seat 220.

[0055] Refer to Figure 1 , according to an embodiment of the present invention, the adapter 400 and the central tube 300 are integrally formed. It can be understood that the central tube 300 and the adapter 400 are integrally formed, which can reduce the docking structure between the central tube 300 and the adapter 400, reduce the influence of the docking structure on the flow rate, and can also reduce potential leakage points or loosening phenomena, improve the overall sealing performance. At the same time, the integrally formed design can also simplify the production process and reduce the production cost. By integrally forming the adapter 400 and the central tube 300 at one time, the processing and assembly steps can be reduced and the production efficiency can be improved.

[0056] Refer to Figure 1, according to an embodiment of the present invention, a cover portion 230 extends from one side of the waterway member 200 towards the tank body 100. The cover portion 230 covers one end of the tank body 100 provided with the tank opening 120, and the adapter base 220 is disposed in the inner cavity of the cover portion 230. It can be understood that by combining the cover portion 230, the adapter base 220 with the tank body 100, the installation process can be simplified and the stability of the overall structure can be improved. At the same time, the cover portion 230 can effectively protect the tank opening 120, preventing external impurities or contaminants from entering the resin tank assembly 10, thereby maintaining the internal cleanliness and filtration effect. The adapter base 220 is disposed in the inner cavity of the cover portion 230, which simplifies the installation process and improves the stability of the overall structure. The adapter base 220 is connected to the tank body 100 through the cover portion 230, forming a complete water conduction path, enabling water to flow out of or into the resin tank more smoothly.
