[0038] A water softener is a device that uses cation exchange resin to remove calcium and magnesium ions from water, reducing the hardness of the raw water and thus softening it. Water softeners are currently widely used in industrial and energy systems, exhibiting significant equipment-related characteristics. In household use, the soft water produced by a water softener typically reduces limescale buildup in water heating equipment such as water heaters, wall-mounted boilers, and electric water heaters, as well as in bathrooms; prevents pipe blockages; reduces the attenuation of heat exchange efficiency in heating equipment; reduces detergent usage; is gentler on the skin; and leaves clothes softer and more vibrant after washing.

[0039] In related technical fields, water softening devices mainly consist of four parts: control valves, resin tanks, brine extractors, and brine containers. The core filter material of a water softening device is softening resin, which is housed in the resin tank, highlighting its importance. When the water softening device is operating, the tank is subjected to significant water pressure. Furthermore, when the tank is installed onto the water system components, the mounting structure between the tank and the components bears considerable pressure, and existing installation structures struggle to guarantee connection strength.

[0040] This invention proposes a resin tank assembly and a water softening device.

[0041] In embodiments of the present invention, such as Figures 1 to 6 As shown, the resin tank assembly 10 includes a resin tank body 100 and a water channel component 200. The resin tank body 100 has a receiving cavity 110 for containing resin and a constriction 131 communicating with the receiving cavity 110. The constriction 131 is located at one end of the resin tank body 100. The end of the resin tank body 100 is provided with a tapered portion 132, which is tapered towards the constriction 131. The tapered portion 132 is provided with a first snap-fit ​​portion 133 along the circumference of the constriction 131. The water channel component 200 has a water channel constructed inside. The water channel component 200 is provided with a connecting port, and the water channel communicates with the constriction through the connecting port. A second snap-fit ​​portion 211 corresponding to the first snap-fit ​​portion 133 is provided on the outer periphery of the connecting port. The second snap-fit ​​portion 211 is connected to the first snap-fit ​​portion 133 by screwing, so as to connect and fix the water channel component 200 and the resin tank body 100, so that the connecting port and the constriction 131 are connected and conductive.

[0042] The resin tank body 100 is generally hollow cylindrical in shape, and a receiving cavity 110 is formed inside the resin tank body 100. The receiving cavity 110 is the main part of the resin tank and is used to store resin. The design of the receiving cavity 110 can have different shapes and sizes according to application requirements to adapt to different resin volumes and performance requirements, and no special limitations are made here.

[0043] A constriction 131 is provided on one end face of the resin tank body 100. The constriction 131 is used to allow and control the flow of fluid into and out of the receiving cavity 110. The size and shape of the constriction 131 can be adjusted according to actual needs to optimize the flow performance of the resin. At the same time, the design of the constriction 131 can reduce the flow area of ​​fluid between the water channel component 200 and the resin tank body 100, thereby reducing the reduction of the force-bearing surface between the resin tank body 100 and the water channel component 200, and thus reducing the spreading force.

[0044] The outer side of the constriction 131 is provided with a tapered section 132 for transition, which can further optimize the contact area between the resin tank and the water channel component 200. Through the gradually narrowed section, it can better adapt to the shape and size of the water channel component 200, guide the fluid, and facilitate the fluid to adapt to the changes in the receiving cavity 110, so as to improve the connection stability and tightness between the two in conjunction with the constriction 131.

[0045] The tapered portion 132 has a first engaging portion 133 along the periphery of the constriction 131. The first engaging portion 133 is used to engage with the second engaging portion 211 on the water channel component 200. The design of the first engaging portion 133 and the second engaging portion 211 allows for a simple and quick connection between the water channel component 200 and the resin tank body 100. Furthermore, the first engaging portion 133's location on the tapered portion 132 ensures the stability and reliability of the connection and effectively reduces the radial area of ​​the resin tank assembly 10. The screw-on connection method also reduces the workload and difficulty during connection, improving the overall practicality and convenience of the assembly.

[0046] The water passage component 200 has a connecting port, allowing water flow to be guided and distributed. In this application, the connecting port is used to connect with the constriction 131 of the resin tank body 100. The shape and size of the connecting port should match the constriction 131 to ensure a tight connection. A second snap-fit ​​portion 211, corresponding to the first snap-fit ​​portion 133, is provided around the connecting port, and the second snap-fit ​​portion 211 matches the first snap-fit ​​portion 133 on the resin tank body 100. Through the screw-lock connection of the first and second snap-fit ​​portions 211, the water passage component 200 and the resin tank body 100 can be securely connected. This connection method provides better stability and reliability, ensuring that the water passage component 200 will not loosen or fall off during use. The screw-lock connection between the first snap-fit ​​portion 133 and the second snap-fit ​​portion 211 in this application requires only a small angle of rotation to reach the desired position, which is simple and quick, effectively reducing installation time and workload. Meanwhile, the snap-fit ​​connection also provides better stability, ensuring a firm and reliable connection between the water system component 200 and the resin tank body 100.

[0047] This application reduces the force-bearing surface between the water channel component 200 and the resin tank body 100 by providing a constriction 131 and a tapered portion 132 around the constriction 131, thereby reducing the spreading force. At the same time, a first snap-fit ​​portion 133 is provided in the tapered portion 132 along the circumference of the constriction 131, and a corresponding second snap-fit ​​portion 211 is provided in the water channel component 200. The first snap-fit ​​portion 133 of the resin tank body 100 and the second snap-fit ​​portion 211 of the water channel component 200 are screwed together to tightly connect the water channel component 200 and the resin tank body 100 together, ensuring the stability and reliability of the connection. Furthermore, the screw-fitting action, combined with the connection between the constriction 131 and the connecting port, connects the resin tank body 100 and the water channel component 200, improving the ease of installation.

[0048] Reference Figures 3 to 6 According to one embodiment of the present invention, the first engaging portion 133 includes a plurality of engaging protrusions 133a, which are arranged circumferentially along the constriction 131. The engaging protrusions 133a and the outer wall of the tapered portion 132 form a groove 133b, and the second engaging portion 211 is slidably engaged with the groove 133b. It is understood that the engaging protrusions 133a cooperate with the outer wall of the tapered portion 132 to form a groove 133b on the side away from the constriction 131. Thus, when the second engaging portion 211 is slidably engaged with the groove 133b, the engaging protrusions 133a can provide a greater axial abutment force, cooperating with the second engaging portion 211 to resist a greater spreading force, and can be more stably fixed in place. Specifically, by slidably engaging the second engaging portion 211 of the water channel component 200 with the groove 133b of the resin tank body 100, a tight connection between the two can be ensured. Due to the design of the snap-fit ​​boss 133a and the slot 133b, the connecting part can withstand greater external forces and vibrations, improving the stability of the entire assembly. Furthermore, this design also helps reduce loosening or detachment caused by vibration or other external forces during use.

[0049] Reference Figure 5 and Figure 6According to one embodiment of the present invention, the second snap-fit ​​portion 211 includes a plurality of snap-fit ​​protrusions 211a, which are correspondingly disposed with the snap-fit ​​groove 133b and are slidably engaged with each other. This application, through the engagement of multiple snap-fit ​​protrusions 211a and the snap-fit ​​groove 133b, can effectively improve the engagement efficiency of the screw-on connection, requiring only a small angle of rotation to reach the desired position, simplifying the installation process and improving installation efficiency. Simultaneously, the arrangement of multiple snap-fit ​​protrusions 211a can also distribute the force at the connection points, improving the strength and stability of the overall structure. Thus, the multi-point connection method can better resist external forces and vibrations, reducing the possibility of loosening or detachment during use. Furthermore, due to the reinforcement of the connection points, the service life of the entire resin tank assembly 10 is also extended.

[0050] Reference Figure 3 and Figure 5 According to one embodiment of the present invention, the slot 133b has a slot inlet 133c and a stop portion 133d, which are disposed opposite to each other at both ends of the slot 133b. It is understood that the slot inlet 133c is opened circumferentially along the resin tank body 100, and communicates with one end of the slot 133b. The slot inlet 133c is used to guide the second snap-fit ​​portion 211 to be correctly inserted into the slot 133b, avoiding misalignment during installation and ensuring precise alignment of the two parts. The stop portion 133d is also disposed circumferentially along the resin tank body 100 and is located at the opposite end of the slot 133b from the slot inlet 133c. Its function is that when the second snap-fit ​​portion 211 is fully inserted into the slot 133b, the stop portion 133d acts as a stop and limit, restricting the second snap-fit ​​portion 211 from moving out of the slot 133b. This ensures the stability of the connection and prevents accidental detachment due to vibration or external force during use. The design of the card inlet 133c and the stop 133d simplifies the installation process, as the user only needs to insert the second card connector 211 into the card inlet 133c and then rotate it until the second card connector 211 abuts against the stop 133d to complete the installation. Furthermore, it simplifies the disassembly process when maintenance or replacement of parts is required.

[0051] Reference Figure 5 and Figure 6According to one embodiment of the present invention, one of the slot 133b or the snap-fit ​​protrusion 211a is provided with a protrusion 133e, and the other is provided with a corresponding recess 211b. Specifically, the second snap-fit ​​portion 211 of the water channel component 200 and the first snap-fit ​​portion 133 on the resin tank body 100 are respectively designed with small cylindrical recesses and protrusions, namely the recess 211b and the protrusion 133e. During the rotation of the water channel component 200, the recess 211b and the protrusion 133e have a certain interference fit. When the second protrusion on the water channel component 200 abuts against the stop portion 133d, the interference fit is eliminated, and the protrusion 133e is engaged with the recess 211b, thereby requiring a large torque for the water channel component 200 to rotate and loosen. In this way, by utilizing the cooperation of the protrusion 133e and the recess 211b, a mutual physical locking mechanism is used to effectively prevent the connection from loosening. The protrusion 133e and the recess 211b fit together precisely, making the connection between the second snap-fit ​​portion 211 and the first snap-fit ​​portion 133 more secure.

[0052] Reference Figure 5 According to one embodiment of the present invention, a clearance portion 133f is formed between two adjacent engaging protrusions 133a. Two adjacent engaging slots 133b are connected in the engagement direction, with the inlet 133c of the latter slot 133b communicating with the clearance portion 133f, while the former slot 133b is separated from the clearance portion 133f by a stop portion 133d. It is understood that the clearance portion 133f is used to axially avoid the second protrusion. Specifically, by providing the clearance portion 133f, a clear channel is formed between adjacent engaging protrusions 133a, allowing the second engaging portion 211 to slide and engage more smoothly. This avoids possible collisions between the engaging protrusions 133a, improving the stability and reliability of the engagement. The two adjacent slots 133b along the engagement direction have their inlet 133c connected to the clearance part 133f, while the first slot 133b is separated from the clearance part 133f by the stop part 133d. This allows the second engaging part 211 to smoothly enter the second slot 133b during the sliding engagement process, and prevents the corresponding second engaging part 211 from sliding into the first slot 133b, avoiding possible installation misalignment and improving the effectiveness and reliability of assembly and disassembly.

[0053] Reference Figure 3 and Figure 4According to one embodiment of the present invention, the resin tank body 100 includes a first tank body 120 and a second tank body 130. A constriction 131 is provided on the second tank body 130. The first tank body 120 is a cylindrical shape with one open end, and the second tank body 130 is connected to the opening. The first tank body 120 and the second tank body 130 together enclose a receiving cavity 110. It is understood that, in this application, the resin tank body 100 can be integrally molded or composed of separate parts. This embodiment uses the resin tank body 100 including the first tank body 120 and the second tank body 130 as an example for illustration. Other embodiments can refer to this embodiment for implementation. The first tank body 120 is a cylindrical shape with one open end, and the second tank body 130 is connected to the opening, together with the first tank body 120, forming the receiving cavity 110. This design facilitates the arrangement of other components within the receiving cavity 110. The design of the first tank body 120 and the second tank body 130 makes the resin tank more flexible and adaptable to different application scenarios and needs. For example, the length or shape of the second tank 130 can be adjusted according to actual needs to adapt to specific installation conditions or usage requirements.

[0054] Reference Figures 3 to 5 According to one embodiment of the present invention, a plug-in post 134 extends from the outer periphery of the constriction 131 toward the water passage component 200. The water passage component 200 is provided with a plug-in interface. The plug-in post 134 and the plug-in interface are movably plugged into each other to connect the receiving cavity 110 and the water passage component 200. This embodiment enhances the connectivity between the receiving cavity 110 and the water passage component 200 through the cooperation of the plug-in post 134 and the plug-in interface. The design of the plug-in post 134 and the plug-in interface makes the connection more stable, reducing the risk of loosening or detachment during use, thereby improving the overall structural stability. Due to the movable plug-in connection of the plug-in post 134 and the plug-in interface, the assembly and disassembly process becomes simple and quick. The user can easily insert or remove the plug-in post 134 by rotating the first locking part 133 and the second locking part 211, thereby achieving connection or disconnection between the water passage component 200 and the receiving cavity 110.

[0055] Reference Figures 3 to 5According to one embodiment of the present invention, an annular sealing groove 134a is provided on the peripheral wall of the plug post 134. The sealing element is sleeved within the annular sealing groove 134a and is interference-fitted between the groove wall of the annular sealing groove 134a and the inner wall of the plug interface. This embodiment, by providing an annular sealing groove 134a on the peripheral wall of the plug post 134 and using an interference fit with the sealing element, greatly enhances the sealing performance of the connection. This effectively prevents fluid leakage at the connection and ensures the normal use of the resin tank assembly 10. The sealing element is installed using a sleeve method, which facilitates the user's maintenance and replacement of the sealing element. When the sealing element is worn or damaged, the user can easily remove it and replace it with a new sealing element, extending the service life of the resin tank. The interference fit design ensures a tight fit between the sealing element and the plug post 134 and the plug interface, reducing the possibility of loosening or displacement during use. By providing an annular sealing groove 134a and a sealing element on the plug post 134, the use of traditional fixing methods and connectors is avoided, simplifying the overall structure and design.

[0056] Reference Figure 1 and Figure 2 According to one embodiment of the present invention, the water channel component 200 extends a cover portion 210 towards the resin tank body 100. The cover portion 210 covers the tapered portion 132, and the second snap-fit ​​portion 211 is disposed around the inner wall of the cover portion 210. This embodiment enhances the overall stability of the resin tank body 100 through the cooperation between the cover portion 210 and the tapered portion 132. The cover portion 210 provides a layer of protection for the structural connection, reducing damage to the structural connection from external factors. Simultaneously, it facilitates the connection of the second snap-fit ​​portion 211, making it easier to align and install the resin tank body 100.
