[0075] A water softener utilizes cation exchange resins to remove calcium and magnesium ions from water, reducing the hardness of the raw water and thereby softening it. Water softeners are currently widely used in industrial and energy systems and possess a strong mechanical nature. In homes, the soft water produced by a water softener typically reduces scale buildup in water heating equipment such as water heaters, wall-mounted boilers, and electric water heaters, as well as in bathrooms. It also prevents pipe blockages, reduces heat exchange efficiency degradation in heating equipment, reduces detergent usage, and is more skin-friendly, resulting in softer, more vibrantly colored clothes.

[0076] In the related art, a waterway plate is connected between the resin tank and the water softener valve to integrate the waterway of the water softener. A central pipe is connected between the resin tank and the waterway plate to discharge the softened water from the resin tank. The existing connection structure between the waterway plate and the central pipe is complex and easily restricts the flow of the central pipe, affecting the water softener's output efficiency.

[0077] In the relevant technical field, the connection structure between the existing water channel components and the central pipe is complex, difficult to assemble and align, and easily mis-installed. Reinstallation requires repeated disassembly and assembly of the tank body, which is not conducive to production.

[0078] The present application provides a resin tank assembly and a water softening device.

[0079] In an embodiment of the present application, as shown in Figures 1 to 4, 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 to connect with the adapter seat of 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 formed between the adapter and the adapter seat.

[0080] The tank body 100 is generally hollow and cylindrical, with a housing 110 formed within it. The housing 110 is the primary portion of the tank body 100 and is used to store resin. The housing 110 can be designed in various shapes and sizes to accommodate varying resin volumes and performance requirements, and is not specifically limited herein.

[0081] 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 flow of fluid 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.

[0082] The water channel member 200 is mounted on the end of the tank body 100 near the tank opening 120 and includes a soft water channel 210. This channel 210 directs the flow of water, allowing the softened water, softened by the resin, to exit the tank body 100 for consumption. An adapter 220 is installed where the water channel member 200 interfaces with the tank opening 120. The end of the adapter 220 facing the tank opening 120 is open 221 to facilitate docking with the central tube 300.

[0083] The central tube 300 is located in the accommodating cavity 110, with a first end of the central tube 300 passing through the tank opening 120. The second end of the central tube 300 is located at the bottom of the accommodating cavity 110 of the tank body 100. The central tube 300 is mainly used as a channel for guiding soft water in the tank body 100.

[0084] The adapter 400 is connected to the first end of the central tube 300 and covers the opening 221 of the adapter seat 220, forming a water-conducting chamber 410. The water-conducting chamber 410 connects the central tube 300 and the soft water channel 210, ensuring smooth water flow. This simplifies the connection between the waterway component 200 and the central tube 300, facilitating alignment and improving installation efficiency. Furthermore, it reduces water flow resistance and enhances filtration efficiency.

[0085] The present application provides an adapter seat 220 at the connection between the waterway plate and the central tube 300, and provides the adapter 400 at the first end of the central tube 300. A water guide chamber 410 is formed between the adapter seat 220 and the adapter 400. The water guide chamber 410 connects the central tube 300 and the soft water flow path. In this way, by providing the water guide chamber 410, the maximum flow rate at the connection between the central tube 300 and the soft water flow path is increased, and the flow restriction caused by the inconsistency of the connection structure and the flow path at the connection between the central tube 300 and the soft water flow path is reduced, thereby effectively improving the soft water output efficiency of the soft water device.

[0086] In some embodiments, the flow rate of the connecting gap 211 is greater than or equal to the flow rate of the water-conducting chamber 410. In this embodiment, the flow rate of the connecting gap 211 is set to be greater than or equal to the flow rate of the water-conducting chamber 410 because the water-conducting chamber 410 is the main water flow channel for soft water in the resin tank assembly 10. The soft water chamber connects the soft water channel 210 and the central tube 300 and is responsible for introducing or extracting water flow into or out of the resin layer. If the flow rate of the connecting gap 211 is less than the flow rate of the water-conducting chamber 410, it will cause the water flow to be poor or even accumulate. This will not only affect the softening effect, but may also cause the impact force of the water flow on the resin layer to be insufficient, affecting the adsorption effect of the resin layer. In order to achieve a flow rate of the connecting gap 211 that is greater than or equal to the flow rate of the water-conducting chamber 410, the connecting gap 211 needs to be accurately designed and calculated. 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. Through precise calculation and design, the size and shape of the connecting gap 211 can be ensured to meet the requirements of the water-conducting chamber 410, thereby achieving optimal water flow. The flow rate of the connecting gap 211 is greater than or equal to the flow rate of the water-conducting chamber 410, allowing the connecting gap 211 to meet the water flow requirements of the water-conducting chamber 410. If the flow rate of the connecting gap 211 is too small, water may accumulate within the water-conducting chamber 410, thereby affecting the filtration effect. By ensuring that the flow rate of the connecting gap 211 is greater than or equal to the flow rate of the water-conducting chamber 410, this accumulation can be avoided and filtration efficiency can be improved. Furthermore, since the flow rate of the connecting gap 211 is optimized, water can be discharged from the resin tank more evenly and stably. This can improve the filtration effect and ensure the quality and output of soft water. Furthermore, since the water flow is better controlled, energy consumption can be reduced, improving the overall performance of the resin tank assembly 10.

[0087] 4 , in some embodiments, a water-conducting chamber 410 extends from the tank opening 120 toward the circumference of the tank body 100. The outer wall of the adapter 220 extends from one side of the waterway member 200 toward the tank body 100 and encloses a water-conducting groove 223. It will be understood that the water-conducting chamber 410 is used to connect the central tube 300 extending from the tank opening 120 with the soft water channel 210 disposed in the waterway member 200. The central axis of the water-conducting chamber 410 and the central axis of the soft water channel 210 may be arranged at an angle to each other, and can be arranged in such a manner as to be perpendicular, acute, or obtuse to each other, as needed. The outer wall of the adapter seat 220 extends from one side of the water channel member 200 toward the tank body 100 to form a water guide groove 223. The end of the guide groove facing the resin tank is an opening 221. The adapter 400 covers this opening 221 to form a water guide chamber 410 between the adapter seat 220 and the adapter 400. This simplifies the installation process and improves installation efficiency. The design of the water guide chamber 410 also reduces the restrictions on water flow caused by the docking structure, ensuring that water flows smoothly through the soft water channel 210 entering the water channel member 200, thereby improving the soft water output rate.

[0088] 4 , in some embodiments, one end of the adapter 220 facing in the circumferential direction is arranged to intersect with a portion of the soft water channel 210, and a connecting notch 211 is provided on a side of the soft water channel 210 corresponding to the adapter 220. The connecting notch 211 is used to connect the soft water channel 210 and the water guide chamber 410. It is understood that the provision of the connecting notch can increase the flow rate at the connecting opening between the soft water channel 210 and the adapter 220, prevent water from accumulating in the water guide chamber 410, and improve the soft water output efficiency.

[0089] In one embodiment, the flow cross-sectional area of ​​the water-conducting chamber 410 is greater than or equal to the flow cross-sectional area of ​​the central tube 300. It will be appreciated that the flow cross-sectional area of ​​the water-conducting chamber 410 being greater than or equal to the flow cross-sectional area of ​​the central tube 300 ensures that water flow through the water-conducting chamber 410 will not encounter flow restriction or excessive resistance. This effectively ensures the efficiency of soft water output. Furthermore, it can reduce water flow resistance, lower energy consumption, and improve the overall performance of the resin tank assembly 10. By optimizing the design of the water-conducting chamber 410 and the central tube 300, the water flow can be better controlled, flowing more evenly and stably through the resin layer, thereby achieving a better filtration effect.

[0090] Referring to Figure 3, in some embodiments, the inner wall of the opening 221 is provided with an annular abutment step 222. An abutment flange 420 extends from the outer periphery of the adapter 400 toward the side of the adapter seat 220, and the abutment step and the abutment flange 420 abut against each other. It is understood that the annular abutment step 222 on the inner wall of the opening 221 mates with the abutment flange 420 extending from the outer periphery of the adapter 400 toward the side of the adapter seat 220. This ensures a tight connection between the adapter 400 and the adapter seat 220, preventing water leakage from the connection, thereby improving filtration efficiency and user safety. The design of the annular abutment step 222 increases the contact area between the adapter 400 and the inner wall of the opening 221, enhancing the stability of the connection. Furthermore, the abutment between the abutment flange 420 and the abutment step forms a closed water-conducting chamber 410, ensuring that water can flow smoothly through the resin layer. Moreover, since the connection between the adapter 400 and the opening 221 is achieved through the abutment between the abutment step and the abutment flange 420, no additional fixing or fastening measures are required, which further improves the alignment accuracy of the adapter 400 and the adapter seat 220 and facilitates alignment installation.

[0091] 3 , in some embodiments, a sealing groove 430 is provided on the outer circumferential wall of the adapter 400. The resin tank assembly 10 further includes a sealing member, which is sleeved within the sealing groove 430 and abuts between the groove wall of the sealing groove 430 and the inner wall of the opening 221. It is understood that the sealing groove 430 is provided on the outer circumferential wall of the adapter 400. The sealing groove 430 is used to accommodate the sealing member to achieve a sealed connection between the adapter 400 and the opening 221. The design of the sealing groove 430 ensures that the sealing member can be securely confined within the sealing groove 430. The sealing member abuts between the groove wall of the sealing groove 430 and the inner wall of the opening 221. This ensures that the sealing member forms an effective sealing layer between the adapter 400 and the opening 221, preventing water or other liquids from leaking. This improves the sealing performance between the adapter 400 and the adapter seat 220.

[0092] Referring to Figure 1 , in some embodiments, the adapter 400 is integrally formed with the center tube 300. It will be appreciated that this integral molding of the center tube 300 and adapter 400 can reduce the need for a docking structure between the two components, thereby reducing the impact of the docking structure on flow. It can also reduce potential leaks or looseness, thereby improving overall sealing performance. Furthermore, the integrated design can simplify the production process and reduce production costs. By molding the adapter 400 and center tube 300 in one piece, processing and assembly steps can be reduced, thereby improving production efficiency.

[0093] 1 , in some embodiments, a cover portion 230 extends from the water channel member 200 toward one side of the tank body 100, and the cover portion 230 covers one end of the tank body 100 provided with the tank mouth 120, and the adapter 220 is provided in the inner cavity of the cover portion 230. It can be understood that by combining the cover portion 230, the adapter 220 and 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 mouth 120 and prevent external impurities or contaminants from entering the interior of the resin tank assembly 10, thereby maintaining the internal cleanliness and filtering effect. The adapter 220 is provided in the inner cavity of the cover portion 230, which simplifies the installation process and improves the stability of the overall structure. The adapter 220 is connected to the tank body 100 through the cover portion 230, forming a complete water guide path, so that water can flow out of the resin tank or flow into the resin tank more smoothly.

[0098] 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 flow of fluid 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.

[0099] The water channel member 200 is mounted on the end of the tank body 100 near the tank opening 120 and includes a soft water channel 210. This channel 210 directs the flow of water, allowing the softened water, softened by the resin, to exit the tank body 100 for consumption. An adapter 220 is installed where the water channel member 200 interfaces with the tank opening 120. The end of the adapter 220 facing the tank opening 120 is open 221 to facilitate docking with the central tube 300.

[0100] The central tube 300 is located in the accommodating cavity 110, with the first end of the central tube 300 passing through the tank opening 120. The second end of the central tube 300 extends into the bottom of the accommodating cavity 110 of the tank body 100. The central tube 300 is mainly used as a channel for guiding the flow of soft water in the tank body 100.

[0101] The adapter 400 is connected to the first end of the central tube 300 and covers the opening 221 of the adapter seat 220, forming a water-conducting chamber 410. The water-conducting chamber 410 connects the central tube 300 and the soft water channel 210, ensuring smooth water flow. This simplifies the connection between the waterway component 200 and the central tube 300, facilitating alignment and improving installation efficiency. Furthermore, it reduces water flow resistance and enhances filtration efficiency.

[0102] In the present application, the adapter seat 220 on the water channel component 200 is set to an open form 221, and the central tube 300 is connected to the adapter seat 220 through the adapter 400. The adapter 400 can be pre-installed with one end of the central tube 300 before docking. When the central tube 300 is connected to the water channel component 200, since the adapter seat 220 is docked with the adapter 400 through the opening 221, the alignment between the two can be facilitated, the connection between the water channel component 200 and the central tube 300 can be simplified, and the installation efficiency can be improved.

[0103] 4 , in some embodiments, a water-conducting chamber 410 extends from the tank opening 120 toward the circumference of the tank body 100. The outer wall of the adapter 220 extends from one side of the waterway member 200 toward the tank body 100 and encloses a water-conducting groove 223. It will be understood that the water-conducting chamber 410 is used to connect the central tube 300 extending from the tank opening 120 with the soft water channel 210 disposed in the waterway member 200. The central axis of the water-conducting chamber 410 and the central axis of the soft water channel 210 may be arranged at an angle to each other, and can be arranged in such a manner as to be perpendicular, acute, or obtuse to each other, as needed. The outer wall of the adapter seat 220 extends from one side of the water channel member 200 toward the tank body 100 to form a water guide groove 223. The end of the guide groove facing the resin tank is an opening 221. The adapter 400 covers this opening 221 to form a water guide chamber 410 between the adapter seat 220 and the adapter 400. This simplifies the installation process and improves installation efficiency. The design of the water guide chamber 410 also reduces the restrictions on water flow caused by the docking structure, ensuring that water flows smoothly through the soft water channel 210 entering the water channel member 200, thereby improving the soft water output rate.

[0104] 4 , in some embodiments, one end of the adapter 220 facing in the circumferential direction is arranged to intersect with a portion of the soft water channel 210, and a connecting notch 211 is provided on a side of the soft water channel 210 corresponding to the adapter 220. The connecting notch 211 is used to connect the soft water channel 210 and the water guide chamber 410. It is understood that the provision of the connecting notch can increase the flow rate at the connecting opening between the soft water channel 210 and the adapter 220, prevent water from accumulating in the water guide chamber 410, and improve the soft water output efficiency.

[0105] Furthermore, the flow rate of the connecting gap 211 is greater than or equal to the flow rate of the water-conducting chamber 410. This embodiment sets the flow rate of the connecting gap 211 to be greater than or equal to the flow rate of the water-conducting chamber 410 because the water-conducting chamber 410 is the main water flow channel for soft water in the resin tank assembly 10. The soft water chamber connects the soft water channel 210 and the central tube 300 and is responsible for introducing or extracting water flow into or out of the resin layer. If the flow rate of the connecting gap 211 is less than the flow rate of the water-conducting chamber 410, it will cause the water flow to be poor or even accumulate. This will not only affect the softening effect, but may also cause the impact force of the water flow on the resin layer to be insufficient, affecting the adsorption effect of the resin layer. In order to achieve a flow rate of the connecting gap 211 greater than or equal to the flow rate of the water-conducting chamber 410, the connecting gap 211 needs to be accurately designed and calculated. 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. Through precise calculation and design, the size and shape of the connecting gap 211 can be ensured to meet the requirements of the water-conducting chamber 410, thereby achieving the best water flow effect. The flow rate of the connecting gap 211 is greater than or equal to the flow rate of the water-conducting chamber 410, so that the connecting gap 211 can meet the water flow requirements of the water-conducting chamber 410. If the flow rate of the connecting gap 211 is too small, it may cause water to accumulate in the water-conducting chamber 410, thereby affecting the filtration effect. By ensuring that the flow rate of the connecting gap 211 is greater than or equal to the flow rate of the water-conducting chamber 410, this accumulation phenomenon can be avoided and the filtration efficiency can be improved. At the same time, because the flow rate of the connecting gap 211 is optimized, the water flow can be discharged from the resin tank more evenly and stably. This can improve the filtration effect and ensure the quality and output of soft water. At the same time, because the water flow is better controlled, energy consumption can be reduced and the overall performance of the resin tank assembly 10 can be improved.

[0106] Referring to Figure 3, in some embodiments, the inner wall of the opening 221 is provided with an annular abutment step 222. An abutment flange 420 extends from the outer periphery of the adapter 400 toward the side of the adapter seat 220, and the abutment step and the abutment flange 420 abut against each other. It is understood that the annular abutment step 222 on the inner wall of the opening 221 mates with the abutment flange 420 extending from the outer periphery of the adapter 400 toward the side of the adapter seat 220. This ensures a tight connection between the adapter 400 and the adapter seat 220, preventing water leakage from the connection, thereby improving filtration efficiency and user safety. The design of the annular abutment step 222 increases the contact area between the adapter 400 and the inner wall of the opening 221, enhancing the stability of the connection. Furthermore, the abutment between the abutment flange 420 and the abutment step forms a closed water-conducting chamber 410, ensuring that water can flow smoothly through the resin layer. Moreover, since the connection between the adapter 400 and the opening 221 is achieved through the abutment between the abutment step and the abutment flange 420, no additional fixing or fastening measures are required, which further improves the alignment accuracy of the adapter 400 and the adapter seat 220 and facilitates alignment installation.

[0107] 3 , in some embodiments, a sealing groove 430 is provided on the outer circumferential wall of the adapter 400. The resin tank assembly 10 further includes a sealing member, which is sleeved within the sealing groove 430 and abuts between the groove wall of the sealing groove 430 and the inner wall of the opening 221. It is understood that the sealing groove 430 is provided on the outer circumferential wall of the adapter 400. The sealing groove 430 is used to accommodate the sealing member to achieve a sealed connection between the adapter 400 and the opening 221. The design of the sealing groove 430 ensures that the sealing member can be securely confined within the sealing groove 430. The sealing member abuts between the groove wall of the sealing groove 430 and the inner wall of the opening 221. This ensures that the sealing member forms an effective sealing layer between the adapter 400 and the opening 221, preventing water or other liquids from leaking. This improves the sealing performance between the adapter 400 and the adapter seat 220.

[0108] In one embodiment, the flow cross-sectional area of ​​the water-conducting chamber 410 is greater than or equal to the flow cross-sectional area of ​​the central tube 300. It will be appreciated that the flow cross-sectional area of ​​the water-conducting chamber 410 being greater than or equal to the flow cross-sectional area of ​​the central tube 300 ensures that water flow through the water-conducting chamber 410 will not encounter flow restriction or excessive resistance. This effectively ensures the efficiency of soft water output. Furthermore, it can reduce water flow resistance, lower energy consumption, and improve the overall performance of the resin tank assembly 10. By optimizing the design of the water-conducting chamber 410 and the central tube 300, the water flow can be better controlled, flowing more evenly and stably through the resin layer, thereby achieving a better filtration effect.

[0109] Referring to Figure 1 , in some embodiments, the adapter 400 is integrally formed with the center tube 300. It will be appreciated that this integral molding of the center tube 300 and adapter 400 can reduce the need for a docking structure between the two components, thereby reducing the impact of the docking structure on flow. It can also reduce potential leaks or looseness, thereby improving overall sealing performance. Furthermore, the integrated design can simplify the production process and reduce production costs. By molding the adapter 400 and center tube 300 in one piece, processing and assembly steps can be reduced, thereby improving production efficiency.

[0110] 1 , in some embodiments, a cover portion 230 extends from the water channel member 200 toward one side of the tank body 100, and the cover portion 230 covers one end of the tank body 100 provided with the tank mouth 120, and the adapter 220 is provided in the inner cavity of the cover portion 230. It can be understood that by combining the cover portion 230, the adapter 220 and 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 mouth 120 and prevent external impurities or contaminants from entering the interior of the resin tank assembly 10, thereby maintaining the internal cleanliness and filtering effect. The adapter 220 is provided in the inner cavity of the cover portion 230, which simplifies the installation process and improves the stability of the overall structure. The adapter 220 is connected to the tank body 100 through the cover portion 230, forming a complete water guide path, so that water can flow out of the resin tank or flow into the resin tank more smoothly.
