Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to a water softener. Background Technology

[0002] 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 strong 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.

[0003] In related technologies, the resin tank of household water softeners is usually large, which severely limits the lateral dimensions of the water softener due to the size of the tank, resulting in a large volume of water softener. Summary of the Invention

[0107] Hard water can have various impacts on daily life and household appliances. For example, it can reduce washing effectiveness, accumulate in water pipes causing reduced water flow, impair the performance and lifespan of appliances, and even cause skin problems. Therefore, people use water softeners to treat tap water in their daily lives. Water softeners effectively remove minerals from hard water, improving water quality and enhancing the quality of life. Typically, water softeners work by using ion exchange to remove calcium and magnesium ions from the water, thus transforming hard water into soft water.

[0108] One common method is using resin for treatment. This resin is a polymer with a special structure and a positively charged surface. When hard water passes through the resin particles, the calcium and magnesium ions in the resin adsorb onto the positively charged surface, replacing the original sodium ions. After a period of time, the resin particles gradually become saturated. At this point, brine is drawn in to clean the resin particles, regenerating them by replacing the adsorbed ions.

[0109] In related technologies, household water softening equipment is limited by the size of the resin tank, which is usually quite large. Common resin tanks on the market are made of fiberglass wrapped with plastic. Due to the winding molding process, the top and bottom ends need to be designed with a tapered design to ensure strength requirements. At the same time, for strength reasons, they are uniformly designed with a circular cross-section. However, household water softeners usually use a single resin tank design with a circular cross-section, while the casing is usually designed with a square shape. Therefore, there is usually a lot of wasted space in the four corners of the casing, which makes the lateral dimensions of the water softener severely limited by the size of the tank.

[0110] Embodiments of the present invention, with reference to Figures 1-45 As shown, a water softener is provided.

[0111] According to one embodiment of the present invention, please refer to... Figure 16 , Figure 18 , Figure 43 and Figure 44According to an embodiment of the present invention, a water softener includes a housing 10, a plurality of resin tanks 400 and a water circuit component 300. The housing 10 forms an accommodating space. The plurality of resin tanks 400 are arranged side by side in the accommodating space along the length direction of the housing 10. The water circuit component 300 is disposed in the accommodating space. A plurality of mounting ports 302 are provided on one side of the water circuit component 300. The mounting ports 302 are connected to the resin tanks 400 one by one.

[0112] In this embodiment, the shell 10 can be a cuboid, and includes a front panel 11, a rear cover 12, an upper top plate 16, a lower bottom plate, and side plates 21 on both sides. These plates enclose a space for accommodating the resin tank 400 and the water circuit component 300. The resin tank 400 can be filled with ion exchange resin to remove hard ions such as calcium and magnesium from the water, thus softening the water. The water circuit component 300 is connected to the resin tank 400 and is used for the inlet and outlet of the resin tank 400.

[0113] It is understood that in this embodiment, by arranging multiple resin tanks 400 side by side along the length of the shell 10, the size of the resin tanks 400 in the width direction is reduced under the condition of filling the same volume of resin. The overall arrangement is rectangular, which makes it convenient to make the whole machine into a thinner cuboid shape, improves the space utilization of the water softener, realizes the miniaturization design of the water softener, and makes it easy to install the water softener in narrow spaces with size restrictions such as cabinets, balconies, and bathroom cabinets, thereby improving the applicability of the water softener.

[0114] According to one embodiment of the present invention, referring to Figure 44 and Figure 45 The water softener also includes a brine tank 500, which is disposed in the housing space. The brine tank 500 is connected to the resin tank 400 to supply brine solution to the resin tank 400 during backwashing. The brine tank 500 is arranged side by side with the resin tank 400 along the length of the housing 10.

[0115] Understandably, the brine tank 500 of the water softener can store salt. When using the water softener, after the resin tank 400 has adsorbed enough hardness ions, a backwashing operation is required. At this time, the salt stored in the brine tank 500 will be dissolved into brine and flow into the resin tank 400 through the backwash valve to regenerate the resin tank 400.

[0116] In one alternative implementation, refer to Figures 43-45As shown, the water softener includes two resin tanks 400 arranged side by side, each resin tank 400 having a filtration space for filtering water. A salt tank 500 has a salt storage space inside, which communicates with the resin tanks 400 and provides salt to the resin tanks 400 to achieve regeneration. In this embodiment, the salt tank 500 and the two resin tanks 400 are arranged side by side along the length of the housing 10, and the salt tank 500 is also snap-fitted to one of the resin tanks 400.

[0117] In this embodiment, two parallel resin tanks 400 are arranged inside the housing 10. This allows the two parallel resin tanks 400 to operate simultaneously, improving water treatment efficiency to some extent. In certain situations, while one resin tank 400 is undergoing regeneration, the other resin tank 400 can continue to provide softened water, achieving continuous water supply and reducing downtime. Furthermore, the parallel arrangement allows the two resin tanks 400 to operate independently; that is, if one resin tank 400 requires maintenance or replacement, the other resin tank 400 can still continue operating, ensuring continuous water supply and system reliability. Most importantly, the parallel arrangement makes more efficient use of space, especially in space-constrained environments. This layout makes the overall size of the water softener more compact and thinner, facilitating installation and integration into existing water treatment systems, and allowing for use in confined spaces.

[0118] In this embodiment, the salt tank 500 and resin tank 400 are placed inside the housing 10 of the water softener and arranged along the length of the housing 10. This makes full use of the water softener's storage space and avoids occupying too much space in the width direction, thereby improving space utilization and enhancing the applicability of the water softener. The salt tank 500 can supply brine through reasonable pipe connections to ensure the normal operation of the water softener.

[0119] According to an embodiment of the present invention, reference Figures 43-45 As shown, the housing 10 includes a front panel 11 and a rear cover 12. The front panel 11 has a salt inlet window 102. The salt tank 500 is disposed on the side of the resin tank 400 facing the front panel 11. The salt tank 500 includes a tank body 510 and a tank cover 520. The tank body 510 is arranged side by side with the resin tank 400. The tank body 510 forms a receiving cavity that communicates with the salt inlet window 102. The tank cover 520 is rotatably disposed on the tank body 510 to open or close the salt inlet window 102.

[0120] It is understood that in this embodiment, the front panel 11 is the side of the water softener facing the user during use, and the rear cover 12 is opposite to the front panel 11, representing the side of the water softener facing away from the user during use. By providing a salt inlet window 102 on the front panel 11, and allowing the tank cover 520 to rotate to open or close the salt inlet window 102, the space occupied by the water softener in the height direction can be reduced, thus decreasing the overall size of the water softener. By making the tank cover 520 rotatable to open or close the salt inlet window 102, when the tank cover 520 is in the closed position, the salt inlet window 102 can be effectively covered, preventing the salt particles in the salt tank 500 from becoming damp, contaminated, or overflowing. When the lid 520 is in the open position, the side of the lid 520 facing the salt inlet window 102 guides the salt particles into the salt tank 500 body. This buffers the salt particles, preventing them from falling directly into the salt tank 500 body and impacting its inner wall. Simultaneously, the guide function ensures the salt particles fall evenly into the salt tank 500, improving the uniformity of the brine in the salt tank 500. Furthermore, the lid 520 can be rotated to open and close, reducing the space occupied by the water softener when closed.

[0121] According to an embodiment of the present invention, reference Figure 44 and Figure 45 At least one side of the salt tank 500 is provided with a second snap-fit ​​structure 540 that snaps into the resin tank 400 to snap-fit ​​connect the salt tank 500 and the resin tank 400.

[0122] In an optional implementation, a second snap-fit ​​structure 540 is used to connect the salt tank 500 and the resin tank 400. This snap-fit ​​installation simplifies the installation and replacement process of the resin tank 400. This quick-connect mechanism allows maintenance personnel to more easily disassemble and replace the resin tank 400, reducing maintenance time and labor intensity. Furthermore, the snap-fit ​​installation provides a robust connection, helping to ensure the stability of the resin tank 400 during operation and reducing potential problems caused by loose connections.

[0123] The second snap-fit ​​structure 540 can be in the form of a hook, pin, magnetic, wedge lock, buckle, slot 15, or elastic fastener. This embodiment does not specifically limit this.

[0124] The number of second snap-fit ​​structures 540 can be one or more. When multiple second snap-fit ​​structures 540 are used, the safety and stability of the connection between the salt tank 500 and the resin tank 400 can be further improved. In an optional embodiment, second snap-fit ​​structures 540 are provided on both sides of the salt tank 500, and the number of second snap-fit ​​structures 540 is multiple. The multiple second snap-fit ​​structures 540 are arranged along the height direction of the housing 10, which further improves the firmness and stability of the connection between the salt tank 500 and the resin tank 400.

[0125] Furthermore, the snap-fit ​​design provides a secure connection between the resin tank 400 and the brine tank 500, ensuring that they will not accidentally separate during water softener operation, thus guaranteeing system stability and safety. This snap-fit ​​design also makes the water softener's components highly modular, allowing for easy addition, removal, or replacement of components as needed, improving system flexibility and scalability. Moreover, the well-designed snap-fit ​​mechanism helps prevent leakage of brine or softened water at the connection points, ensuring efficient system operation. For users, this snap-fit ​​design also simplifies the operation process, allowing even non-professionals to easily perform maintenance and component replacement, reducing the difficulty of use.

[0126] Furthermore, the above design allows the system to be expanded or reduced as needed. If increased processing capacity is required, more resin tanks 400 can be simply added without requiring major modifications to the entire system. Moreover, the side-by-side arrangement and snap-fit ​​mounting design likely reduces manufacturing and maintenance costs. The simplified installation process reduces the time and materials required for installation and maintenance, thereby lowering overall costs.

[0127] According to an embodiment of the present invention, reference Figures 43-45 At least one of the height and width of the salt tank 500 and the resin tank 400 is equal.

[0128] In one alternative embodiment, the brine tank 500 and the resin tank 400 are of equal height. In another alternative embodiment, the brine tank 500 and the resin tank 400 are of equal width. In yet another alternative embodiment, the brine tank 500 and the resin tank 400 are of equal height and equal width. This design allows the two components to better cooperate with each other, forming a compact structure and minimizing the overall size of the water softener.

[0129] By making the height and width of the brine tank 500 and the resin tank 400 equal, they can be arranged more compactly inside the water softener's housing 10 during installation. This compact arrangement makes full use of the water softener's storage space, avoids wasting space, and improves the water softener's space utilization rate.

[0130] According to one embodiment of the present invention, the housing 10 includes a plurality of detachably mounted housing plates 13, the plurality of housing plates 13 being arranged to form an accommodating space, and at least one housing plate 13 being detachably connected to at least one of the resin tank 400 and the salt tank 500.

[0131] It is understood that the housing 10 includes multiple housing plates 13, which are detachably connected. These housing plates 13 can be further subdivided into a front panel 11, a rear cover 12, an upper top plate 16, a lower bottom plate, and side panels 21, collectively forming an accommodating space. The detachable connection between the housing plates 13 facilitates the maintenance and replacement of the water softener. When maintenance or replacement of water softener components is required, the user only needs to disassemble the corresponding housing plate 13. This also makes the water softener more flexible and adaptable to different installation environments and usage needs.

[0132] In one optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400. For example, the bottom plate and the side plates 21 on both sides are detachably connected to the resin tank 400. This facilitates user maintenance and replacement of the resin tank 400 and ensures that the shell 10 and the resin tank 400 will not accidentally separate during the operation of the water softener, thereby guaranteeing the stability and safety of the system. In another optional embodiment, at least one shell plate 13 is detachably connected to the brine tank 500. For example, the bottom plate and the front cover plate are detachably connected to the brine tank 500. This facilitates user maintenance and replacement of the brine tank 500 and ensures that the shell 10 and the brine tank 500 will not accidentally separate during the operation of the water softener, thereby guaranteeing the stability and safety of the system. In yet another optional embodiment, the detachable connection of at least one shell plate 13 to the resin tank 400 and the detachable connection of at least one shell plate 13 to the brine tank 500 can be designed according to actual application requirements, and this embodiment does not impose specific limitations on this.

[0133] According to an embodiment of the present invention, reference Figures 43-45 At least one of the salt tank 500 and resin tank 400 has a first snap-fit ​​structure 530 on its outer side, and at least one shell plate 13 is snap-fitted to the first snap-fit ​​structure 530 so that the shell plate 13 fits against the outer side of the salt tank 500 or resin tank 400.

[0134] It is understood that in this embodiment, a first snap-fit ​​structure 530 is provided on the brine tank 500 or resin tank 400. When assembling the water softener, the brine tank 500 and resin tank 400 can be snapped together first through the second snap-fit ​​structure 540. Then, the shell plate 13 is installed on the outside of the brine tank 500 or resin tank 400. The shell plate 13 can be directly installed on the outside of the brine tank 500 or resin tank 400 through the first snap-fit ​​structure 530, so that the shell plate 13 is directly attached to the outside of the brine tank 500 or resin tank 400, making the connection between the shell plate 13 and the brine tank 500 or resin tank 400 tighter, thereby increasing the stability and robustness of the water softener. Moreover, since the shell plate 13 is directly attached to the outside of the brine tank 500 or resin tank 400, the water softener can be made thinner and lighter, thereby saving space and facilitating installation.

[0135] The number of first snap-fit ​​structures 530 can be one or more. When multiple first snap-fit ​​structures 530 are used, the safety and stability of the connection between the shell plate 13 and the salt tank 500 or the resin tank 400 can be further improved. In an optional embodiment, first snap-fit ​​structures 530 are provided on both sides of the salt tank 500 or the resin tank 400, and the number of first snap-fit ​​structures 530 is multiple. The multiple first snap-fit ​​structures 530 are arranged along the height direction or length direction of the shell 10, which further improves the firmness and stability of the connection between the salt tank 500 and the resin tank 400.

[0136] According to an embodiment of the present invention, reference Figures 43-45 At least one of the two adjacent shell plates 13 is provided with a buckle 14, and the other shell plate 13 is provided with a slot 15 that matches the buckle 14.

[0137] It is understandable that in this embodiment, two adjacent shell plates 13 can be connected by buckles 14 and slots 15. The design of buckles 14 and slots 15 can facilitate the installation and disassembly of the water softener shell plates 13, while ensuring the stability and tightness of the connection, and also making it easier for users to perform maintenance and cleaning.

[0138] It is understandable that there can be multiple clips 14 and slots 15, and the clips 14 and slots 15 are set one-to-one to ensure that the connection between the shell plates 13 is tighter and more stable, thus ensuring the stability and robustness of the water softener.

[0139] According to an embodiment of the present invention, reference Figure 16 and Figure 18 The water channel component 300 is positioned above the resin tank 400.

[0140] In related technologies, the water circuit component 300 has a complex structure and is positioned relative to the resin tank 400 in the width direction of the housing 10, resulting in a large volume of the water softener. To address this issue, in this embodiment, the water circuit component 300 is positioned above the resin tank 400. Alternatively, the water circuit component 300 can be arranged along the length direction of the housing 10, i.e., the water circuit component 300 and the resin tank 400 are stacked vertically along the length direction. This ensures smooth water flow inside the water softener, facilitates maintenance and operation, reduces the space occupied by the water softener in the width direction, makes the structure more compact, and thus reduces the volume of the water softener.

[0141] According to an embodiment of the present invention, reference Figures 16-18 The water channel component 300 defines multiple flow channels 303 arranged in parallel, each flow channel 303 corresponding to a resin tank 400, so that multiple resin tanks 400 are connected in parallel.

[0142] Understandably, in this embodiment, each resin tank 400 has its own independent flow channel 303. After water enters the water circuit component 300, it can enter each resin tank 400 through different flow channels 303. After being treated within the resin tank 400, the water flows out of the water softener for user use. This parallel arrangement allows multiple resin tanks 400 to work simultaneously without interfering with each other. Each resin tank 400 is equivalent to an independent processing unit, capable of performing softening treatment separately, thus improving the overall processing efficiency and capacity of the water softener.

[0143] By arranging multiple resin tanks 400 in parallel and defining corresponding flow channels 303, the water softener can more flexibly meet different water treatment needs. At the same time, maintaining the independent operation of the resin tanks 400 can also prevent the failure of one resin tank 400 from affecting the normal operation of the entire system.

[0144] According to an embodiment of the present invention, reference Figure 18 Along the height direction of resin tank 400, the cross-sectional area of ​​resin tank 400 is equal.

[0145] In one optional embodiment, the resin tank 400 has a circular cross-section, and the diameter of the cross-section of the resin tank 400 is equal along the height direction. It is understood that by making the resin tank 400 have a uniform diameter along its axis, this embodiment increases the proportion of the resin tank 400 within the accommodating space, thereby increasing the proportion of the resin tank 400 in the accommodating space. Simultaneously, with the same resin capacity, the axial height of the resin tank 400 can be reduced, which is beneficial for achieving a miniaturized design of the water softening device.

[0146] According to an embodiment of the present invention, reference Figures 16-18 The resin tank 400 is detachably connected to the mounting port 302; or, the water channel component 300 is integrally formed with the resin tank 400.

[0147] Understandably, in one alternative embodiment, the resin tank 400 has external threads, and the mounting port 302 has internal threads. The water system component 300 can be securely connected to the resin tank 400 via a detachable connection between the resin tank 400 and the mounting port 302. This connection method provides better stability and reliability, ensuring that the water system component 300 will not loosen or fall off during use.

[0148] In another alternative embodiment, the water channel component 300 and the resin tank 400 are integrally formed. It is understood that integrally forming a portion of the water channel component 300 onto the resin tank 400 reduces the need for assembly structures between the water channel component 300 and the resin tank 400, reduces the space occupied by the assembly structures, further improves the utilization rate of the space, and facilitates the miniaturization design of the resin tank 400. Simultaneously, the integral forming of the water channel component 300 and the resin tank 400 simplifies the assembly process, improves assembly efficiency, and also enhances the sealing performance of the water channel component 300.

[0149] According to an embodiment of the present invention, reference Figures 43-45 The resin tank 400 has side plates 21 extending from both sides. The side plates 21 are adapted to be connected to the shell 10. The side plates 21 define the mounting cavity. The water channel component 300 is disposed in the mounting cavity.

[0150] It is understood that in this embodiment, side plates 21 are provided on both sides of the resin tank 400 extending in the height direction of the housing 10. Through the connection between the side plates 21 and the housing 10, the resin tank 400 can be firmly fixed inside the water softener, ensuring its positional stability. At the same time, the mounting cavity defined by the side plates 21 can provide a dedicated space for the water circuit components 300, allowing them to be arranged and installed in an orderly manner.

[0151] The installation cavity houses the water circuit component 300, making the water system of the water softener more centralized and compact, facilitating maintenance and operation. The cavity design also effectively isolates the water circuit component 300 from other parts, preventing mutual interference. Therefore, the side plate 21 and the defined installation cavity provide better connectivity and support, and offer an orderly space for the installation of the water circuit component 300. This design optimizes the structural layout of the water softener, improving its stability and ease of use.

[0152] According to an embodiment of the present invention, reference Figures 43-45 The water softener also includes a valve assembly 100 and an adapter assembly 200. The valve assembly 100 is disposed in the accommodating space, and the adapter assembly 200 connects the valve assembly 100 and the water circuit component 300 to control the flow direction of water within the resin tank 400. The adapter assembly 200 and the water circuit component 300 are detachably connected. The valve assembly 100 can control the inflow and outflow of water by switching it on and off, thereby controlling the water circuit within the resin tank 400. The adapter assembly 200 connects the valve assembly 100 and the water circuit component 300. It can be detached from the water circuit component 300 via threads, quick couplings, or other connection methods. This design makes maintenance of the water softener more convenient; when the water circuit component 300 needs to be replaced or cleaned, it can be easily disassembled from the adapter assembly 200.

[0153] Through the design of valve assembly 100 and adapter assembly 200, the water softener can control the flow direction of water in resin tank 400 and facilitate the replacement and maintenance of water circuit components 300. This design improves the functionality and maintainability of the water softener, making it more suitable for different water treatment needs.

[0154] In related technologies, the water channel component 300 typically integrates various channels for communicating with the resin tank 400, as well as devices and passages for controlling salt absorption. In order to facilitate the arrangement of various passages and devices, the overall structure is relatively large, especially with a large dimensional extension in the width direction of the entire water channel component 300. This makes the entire water channel component 300 structurally complex, difficult to manufacture, and space-consuming. In particular, the water channel component 300 requires more space in the width direction to achieve its own layout.

[0155] According to an embodiment of the present invention, reference Figures 43-45 The water softener includes a housing 10, a resin tank 400, a water circuit component 300, a valve assembly 100, and a connecting assembly 200. The housing 10 forms a receiving space, the resin tank 400 is disposed in the receiving space, the water circuit component 300 is disposed in the receiving space and located above the resin tank 400, the water circuit component 300 is connected to the resin tank 400, and the valve assembly 100 is connected to the water circuit component 300 through the connecting assembly 200 to control the flow direction of water in the resin tank 400.

[0156] It is understood that in this embodiment, by independently setting the valve assembly 100, the adapter assembly 200, and the water circuit component 300, the overall structure of the water circuit is simplified, the manufacturing difficulty of the water circuit component 300 is reduced, and the water circuit component 300 is set above the resin tank 400. The resin tank 400 can be stacked vertically, reducing the bottom area occupied by the water softener. Furthermore, the individual connection of each component facilitates the overall layout, thereby simplifying the overall structure, improving the space utilization of the water softener, and realizing the miniaturization design of the water softener. This makes it easier to install the water softener in narrow spaces with size limitations, such as cabinets, balconies, and bathroom vanities, thus improving the applicability of the water softener.

[0157] During the switching process of various water channels, there are two main states: one is the soft water channel state for softening water quality, and the other is the regeneration water channel state for regenerating resin particles. In the soft water channel state, the water enters from the resin filling area at the top of the resin tank 400, then rises through the central pipe 410 and exits. In the regeneration water channel state, the water enters from the central pipe 410, then rises through the resin particle filling area and exits. That is, the flow direction of the regeneration water channel and the soft water channel need to be opposite. In this embodiment, the water channel component 300 is used to connect with the resin tank 400, and the flow direction of the water channel is controlled by the connecting component 200 connected to it. This achieves the formation of the two main water channels. Furthermore, by setting the connecting component 200 and the water channel component 300 separately, the overall layout is facilitated, and the overall preparation difficulty and manufacturing cost are reduced.

[0158] In this embodiment, the valve assembly 100 can be a conventional multi-way control valve body. A multi-way control valve body typically has five functional positions: water supply, backwash, regeneration, water replenishment, and forward wash. The water supply, water replenishment, and forward wash functional water paths flow in the forward direction, meaning the water flow direction in the resin tank 400 is the same as the soft water path in this example. The backwash and regeneration functional water paths flow in the reverse direction, meaning the water flow direction in the resin tank 400 is the same as the regeneration water path in this embodiment. The multi-way valve body switches between the various water paths through its valve core 140. In this embodiment, the multi-way control valve body is connected to the adapter assembly 200 so that the adapter assembly 200 can control the water flow direction accordingly.

[0159] Understandably, reference Figure 18 As shown, the resin tank 400 in each embodiment of this application can adopt a conventional resin tank structure, that is, a barrel structure for filling resin particles, and an independent central tube 410 inside the barrel. The resin filling part 420 is located on the periphery of the central tube 410, and the water passage achieves softening and other functions by contacting the resin particles inside the resin tank 400.

[0160] According to an embodiment of the present invention, reference Figures 43-45 The adapter 200 and the valve assembly 100 are arranged side by side above the water passage component 300 along the length of the housing 10. The valve assembly 100 is connected to the external water passage through the rear cover plate 12 of the housing 10.

[0161] Understandably, in this embodiment, arranging the adapter assembly 200 and valve assembly 100 side-by-side along the length of the housing 10 above the water circuit component 300 reduces the space occupied in the width direction, making the water softener's structure more compact and effectively reducing its size. This design allows the various components of the water softener to be arranged more closely together, saving space and making the water softener more suitable for installation in environments with limited space, such as homes or offices.

[0162] In this embodiment, the valve assembly 100 is connected to the external water system via the rear cover plate 12 of the housing 10. That is, the water softener's inlet and outlet are located at the rear cover plate 12 of the housing 10, minimizing the space occupied by the water softener. This is especially important for installation in environments with limited space, such as kitchens and bathrooms. By placing the inlet and outlet at the back, space is effectively saved, making it easier to integrate the water softener into existing layouts without requiring long pipes for water system connections.

[0163] According to an embodiment of the present invention, reference Figures 43-45 The water softener also includes a control box 30, which is connected to the valve assembly 100. The control box 30, the adapter assembly 200 and the valve assembly 100 are arranged side by side above the water circuit component 300 along the length of the housing 10.

[0164] It is understood that in this embodiment, the water softener typically also includes a control box 30, which is used to control the operation of the water softener. The control box 30 is typically connected to the valve assembly 100, and controls the opening and closing of the valve assembly 100 through control signals, thereby adjusting the working state of the water softener. To make the overall structure of the water softener more compact, the control box 30, the adapter assembly 200, and the valve assembly 100 are arranged side by side along the length of the housing 10 above the water circuit component 300. This design can maximize the use of the space in the housing 10, tightly combine the various components, reduce the space occupied in the width direction, and further reduce the size of the water softener.

[0165] This layout allows the key components of the water softener to work together seamlessly within a limited space, improving the overall performance and reliability of the water softener. At the same time, this design also facilitates maintenance and repair, making operation and upkeep easier for users.

[0166] According to an embodiment of the present invention, reference Figures 43-45 The housing 10 includes a removable top plate 16 that covers the control box 30, the adapter assembly 200, and the valve assembly 100.

[0167] Understandably, in this embodiment, the housing 10 includes a removable top plate 16, which is mounted above the control box 30, the adapter assembly 200, and the valve assembly 100, serving to protect these critical components. The design of the top plate 16 effectively prevents dust, debris, and other external substances from entering the water softener during normal operation, maintaining the cleanliness and normal operation of the equipment. Simultaneously, the removable design of the top plate 16 facilitates the maintenance and repair of the water softener. When maintenance, replacement, or adjustment of the control box 30, adapter assembly 200, or valve assembly 100 is required, the user can easily access the internal components of the water softener by simply opening the top plate 16, making the maintenance process more efficient and convenient.

[0168] Furthermore, placing the top plate 16 directly over the control box 30, the adapter assembly 200, and the valve assembly 100 helps reduce the space occupied by the water softener. The compact design of the top plate 16 makes the overall structure of the water softener more compact, occupies less space, and makes it easier to integrate the water softener into different environments.

[0169] According to an embodiment of the present invention, reference Figures 43-45 The water softener also includes a brine tank 500, which is located on the side of the housing 10 near the front panel 11. The brine tank 500 is connected to the adapter 200 through a brine suction pipe 550. The brine tank 500 is injected with water and sucked up with brine by the control of the valve assembly 100. The adapter 200 is located on the side of the valve assembly 100 near the brine tank 500.

[0170] Understandably, in this embodiment, for ease of use and maintenance, the salt tank 500 is typically positioned on the side of the accommodating space near the front panel 11 of the housing 10. This placement allows users to more easily add or replace salt, and also facilitates cleaning and maintenance of the salt tank 500. The salt tank 500 is connected to the adapter assembly 200 via a salt suction pipe 550. The function of the salt suction pipe 550 is to transport salt from the salt tank 500 to the adapter assembly 200 for the water softener to prepare and regenerate the brine solution. The adapter assembly 200 is typically positioned on the side of the valve assembly 100 near the salt tank 500, which reduces the length of the salt suction pipe 550 and makes the water softener more compact. This design reduces the resistance and pressure loss of the salt suction pipe 550, improves the efficiency of brine delivery, and also reduces the size of the water softener.

[0171] According to an embodiment of the present invention, reference Figures 43-45 The water softener also includes an overflow pipe 40. The rear cover plate 12 of the housing 10 is provided with a through-plate connector 103. The overflow pipe 40 is installed on the outer wall of the resin tank 400. One end of the overflow pipe 40 is connected to the salt tank 500, and the other end is adapted to communicate with the outside through the through-plate connector 103.

[0172] It is understood that in this embodiment, an overflow port can be added to the back side of the salt tank 500. The overflow port is connected to the outside through the overflow pipe 40. When the water level in the salt tank 500 is too high, the excess water can be discharged through this overflow pipe 40 to prevent water from overflowing directly from the top of the salt tank 500 and causing dampness and pollution inside the equipment or the surrounding environment.

[0173] The overflow pipe 40 can be installed on the outer wall of the resin tank 400, that is, by installing the overflow pipe 40 along the length of the shell 10. The first end of the overflow pipe 40 is connected to the overflow port of the brine tank 500. This design can guide the water that may overflow through the pipe to a safe drainage position, ensuring the stability of the liquid level in the brine tank 500. By setting a through-plate connector 103 on the rear cover plate 12 of the water softener, which is connected to the second end of the overflow pipe 40, the overflow water is guided to the sewer or other suitable location for discharge, ensuring the sealing and effectiveness of the entire anti-overflow structure. In addition, by arranging the overflow pipe 40 laterally from front to back, the thickness of the water softener can be reduced, which is more conducive to miniaturization design and can adapt to various narrow installation spaces, improving the user's installation flexibility and user experience.

[0174] According to an embodiment of the present invention, reference Figures 43-45 The housing 10 is provided with a support member 17, which connects the resin tank 400 and the salt tank 500, and is located above the salt tank 500.

[0175] It is understood that in this embodiment, a support member 17 is provided inside the housing 10. The support member 17 is mainly used to fix and support the resin tank 400 and brine tank 500 inside the water softener. This ensures that the water softener will not shake or shift during operation, thereby guaranteeing the normal operation and service life of the water softener.

[0176] Support component 17 connects the resin tank 400 and the brine tank 500, and is positioned above the brine tank 500. This design allows for a more reasonable distance between the various components and pipes inside the water softener, avoiding mutual interference and friction. Simultaneously, the position of support component 17 also makes the water softener more compact and stable, thereby reducing noise and vibration during operation.

[0177] In addition, the support member 17 may be provided with a snap-fit ​​structure for snapping with the shell plate 13, so that the water softener forms an integral structure, thereby enhancing the overall performance and stability of the water softener. The support member 17 may also be provided with a mounting part for installing and fixing the control box 30, preventing the control box 30 from loosening and shaking.

[0178] According to an embodiment of the present invention, reference Figures 43-45The housing 10 includes multiple detachable shell plates 13, which are arranged to form an accommodating space. At least one shell plate 13 is detachably connected to at least one of the resin tank 400, water circuit component 300, valve assembly 100, and adapter assembly 200.

[0179] It is understood that in this embodiment, the housing 10 includes multiple housing plates 13, which are detachably connected. These housing plates 13 can be further subdivided into a front panel 11, a rear cover 12, an upper top plate 16, a lower bottom plate, and side panels on both sides, collectively forming an accommodating space. The detachable connection between the multiple housing plates 13 facilitates the maintenance and replacement of the water softener. When maintenance or replacement of water softener components is required, the user only needs to disassemble the corresponding housing plate 13. This also makes the water softener more flexible and adaptable to different installation environments and usage needs.

[0180] In one optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400, such as the bottom plate and the side plates 21 on both sides, facilitating user maintenance and replacement of the resin tank 400. This also ensures that the shell 10 and the resin tank 400 will not accidentally separate during the operation of the water softener, thereby guaranteeing the stability and safety of the system. In another optional embodiment, at least one shell plate 13 is detachably connected to the valve assembly 100, facilitating the installation and fixation of the valve assembly 100, as well as its disassembly and maintenance.

[0181] In other embodiments, at least one shell plate 13 is detachably connected to the brine tank 500, such as the bottom plate and the front cover plate, which facilitates the user to maintain and replace the brine tank 500 and ensures that the shell 10 and the brine tank 500 will not accidentally separate during the operation of the water softener, thereby ensuring the stability and safety of the system.

[0182] According to an embodiment of the present invention, reference Figures 43-45 Side plates 21 are provided on both sides of the resin tank 400 or water circuit component 300. The side plates 21 are adapted to be connected to the housing 10. The side plates 21 define the mounting cavity. The valve assembly 100 and the adapter assembly 200 are both provided in the mounting cavity.

[0183] In an optional embodiment, side plates 21 extend from both sides of the resin tank 400 along the height direction of the housing 10. The connection between the side plates 21 and the housing 10 securely fixes the resin tank 400 inside the water softener, ensuring its positional stability. At the same time, the mounting cavity defined by the side plates 21 provides a dedicated space for the water circuit components 300, valve assembly 100, and adapter assembly 200, allowing them to be arranged and installed in an orderly manner.

[0184] In an optional embodiment, side plates 21 extend from both sides of the water circuit component 300 along the height direction of the housing 10. The connection between the side plates 21 and the housing 10 securely fixes the water circuit component 300 and the resin tank 400 inside the water softener, ensuring their positional stability. Simultaneously, the mounting cavity defined by the side plates 21 provides a dedicated space for the valve assembly 100 and the adapter assembly 200, allowing for their orderly arrangement and installation.

[0185] The installation cavity houses the water circuit component 300, making the water system of the water softener more centralized and compact, facilitating maintenance and operation. The cavity design also effectively isolates the water circuit component 300 from other parts, preventing mutual interference. Therefore, the side plate 21 and the defined installation cavity provide better connectivity and support, and offer an orderly space for the installation of the water circuit component 300. This design optimizes the structural layout of the water softener, improving its stability and ease of use.

[0186] According to an embodiment of the present invention, reference Figure 16 , Figure 18 and Figure 43 The water softener includes multiple resin tanks 400 arranged side by side, and multiple installation ports 302. The multiple resin tanks 400 are arranged side by side in the accommodating space along the length of the housing 10.

[0187] Understandably, in this embodiment, the resin tank 400, as one of the core components of the water softener, is placed inside the water softener. The resin tank 400 comprises multiple resin tanks 400, which are arranged side-by-side along the length of the water softener on the back side of the brine tank 500. This side-by-side layout fully utilizes the internal space of the water softener, avoiding an increase in overall thickness due to component stacking. By arranging the resin tanks 400 and brine tank 500 side-by-side, rather than stacking them vertically or crosswise, the entire water softener maintains functional integrity while effectively reducing the thickness of the equipment, meeting the requirements of ultra-thin design, and is particularly suitable for environments with limited installation space. Furthermore, the compact side-by-side arrangement of the resin tanks 400 and brine tank 500 reduces the complexity and length of internal piping connections, which not only improves water exchange efficiency but also reduces equipment manufacturing costs and potential failure rates, further enhancing the user experience and durability of the product.

[0188] Specifically, if multiple resin tanks 400 operating in parallel are used, when one resin tank 400 reaches saturation, the other unsaturated resin tanks 400 can continue ion exchange, thus ensuring a continuous supply of softened water and improving system stability and reliability. Furthermore, the water flow rate and softening effect can be flexibly adjusted by changing the operating sequence of the resin tanks 400 or configuring resin tanks 400 of different capacities, according to actual needs, achieving precise control of the water softening process.

[0189] Therefore, this embodiment, through the rational design of the number and layout of the 400 resin tanks, not only achieves the ultra-thin transformation of the water softener, but also improves its functionality, ease of use and work efficiency, significantly improving the user experience.

[0190] In one optional embodiment, there are multiple mounting ports 302, which are spaced apart along the length of the water channel component 300. Typically, to avoid complex flow channel 303 construction, they are connected as individual resin tanks 400. However, when a single resin tank 400 contains the same number of resin particles, it often requires a larger diameter. An excessively large diameter will affect the contact effect between the raw water and the resin, and also results in a larger overall footprint in the width direction. In this embodiment, the separate arrangement of the water channel component 300 and the adapter component 200 simplifies the construction of the water channel component 300. An installation port 302 is constructed on the water channel component 300, which can connect to the resin tank 400. This allows multiple installation ports 302 to be arranged along the length of the water channel component 300 for installing the resin tank 400. The installation of multiple resin tanks 400 enables the same number of resin particles to be achieved through the distributed multiple resin tanks 400, resulting in a smaller volume of a single resin tank 400 and consequently, a smaller overall space occupied by the water channel component 300 in the width direction.

[0191] In a specific configuration, the water channel component 300 has a first water channel and a second water channel. The first water channel is connected to the resin filling section 420 of each resin tank 400, and the second water channel is connected to the central tube 410 of each resin tank 400. This allows the working medium to enter the resin filling section 420 of each resin tank 400 through the first water channel, and similarly, the working medium can also enter the central tube 410 of each resin tank 400 through the second water channel.

[0192] In specific applications, in some embodiments, the water channel component 300 has two mounting ports 302, which are spaced apart along the extension direction of the water channel component 300. Of course, in other embodiments, the number of water channel components 300 can be three, four, etc. The embodiments and accompanying drawings of this application illustrate examples with two mounting ports 302.

[0193] According to an embodiment of the present invention, reference Figures 16-18 The water system component 300 is constructed with a first connection end 330 and a second connection end 340 communicating with the mounting port 302. The adapter component 200 is connected to the water system component 300 through the first connection end 330 and the second connection end 340, and the first connection end 330 and the second connection end 340 are located on the same one of the plurality of mounting ports 302.

[0194] The water system component 300 includes a first connecting end 330 and a second connecting end 340 communicating with the mounting port 302. The adapter component 200 is connected to the water system component 300 through the first connecting end 330 and the second connecting end 340. The first connecting end 330 enables the input and output of the working fluid, and the second connecting end 340 also enables the input and output of the working fluid. The adapter component 200 controls whether the input working fluid enters through the first connecting end 330 or the second connecting end 340 to switch the water flow direction. Furthermore, the connection between the adapter component 200 and the water system component 300 through the connecting ports facilitates installation, subsequent maintenance, and replacement, reducing user operating costs.

[0195] Understandably, integrating some components and channels into the hydraulic plate makes the maintenance of the water channel component 300 complex and the replacement cost high. In this embodiment, the adapter component 200 is connected to the water channel component 300 through a connection port. The adapter component 200 controls the water flow direction, and the water channel component 300 enables communication with the resin tank 400. This allows for timely repair if either component malfunctions, reducing the difficulty of maintenance and the cost of replacement.

[0196] In the specific configuration, both the first connecting end 330 and the second connecting end 340 are protruding, and are connected and positioned to the adapter component 200 through the protruding ports. It can be understood that the water channel component 300 is a plate-like structure, and the adapter component 200 is mounted on the water channel component 300. During assembly, it needs to be aligned with the position of the connecting ports. In this embodiment, the first connecting end 330 and the second connecting end 340 are protruding, which makes it easier to find the assembly position during assembly, facilitating the assembly and disassembly of the adapter component 200.

[0197] In practical applications, the first connecting end 330 and the second connecting end 340 are arranged side by side along the width direction of the water channel component 300. This arrangement is beneficial for the layout of the adapter component 200 and for the assembly and connection between the adapter component 200 and the water channel component 300.

[0198] According to one embodiment of the present invention, the first connecting end 330 and the second connecting end 340 are located on the same of a plurality of mounting ports 302. The plurality of mounting ports 302 are used to mount resin tanks 400, and each resin tank 400 can communicate with the first connecting end 330 and the second connecting end 340 to realize the input or output of the working fluid. In this embodiment, the first connecting end 330 and the second connecting end 340 are both located on the same mounting port 302, which provides sufficient space on the remaining mounting ports 302 to accommodate the assembly of other components, thereby improving the flexibility of the layout of each component.

[0199] In a specific configuration, the water channel component 300 has two mounting ports 302, which are arranged at intervals along the length of the flow channel 303 component. Both mounting ports 302 are located on one of the mounting ports 302, which creates a clearance space on the other mounting port 302. The main body 301 of the valve assembly 100 and the adapter assembly 200 can be located within this clearance space, making the valve system structure in this embodiment compact, reducing the width, and facilitating miniaturization design.

[0200] In practical applications, the first connection end 330 and the second connection end 340 are located on the side of one mounting port 302 closer to the other mounting port 302. This reduces the distance difference between the respective port positions and the centers of the two mounting ports 302, minimizing the path difference for the water to reach the centers of the two mounting ports 302. It is understood that the longer the path of water flow in the pipeline, the greater the loss in output performance. This method achieves a compact overall component layout and reduces the difference in water delivery capacity caused by the path difference between the two sides, thus achieving a compact overall structural layout and a balance between performance.

[0201] In some embodiments, the number of mounting ports 302 is greater than two. In this case, the multiple mounting ports 302 are distributed at intervals along a straight line, and the mounting ports 302 with the first connecting end 330 and the second connecting end 340 are located at the end positions. When the valve system is installed, it is usually located inside the entire equipment housing 10 to achieve control of the entire water circuit. The limited internal space makes installation and subsequent maintenance difficult. In this embodiment, the first connecting end 330 and the second connecting end 340 are set on the mounting port 302 at one end. This is beneficial for layout, as it can well expose the connection position and realize installation and disassembly. Moreover, since the connection port is offset on the mounting port 302 at the end, the clearance space on the remaining mounting ports 302 is increased, which is beneficial for the layout of component connections and improves the flexibility of its layout.

[0202] In a specific configuration, the water channel component 300 includes a first water channel and a second water channel. A first connecting end 330 is connected to the first water channel, and a second connecting end 340 is connected to the second water channel. The first water channel connects the first connecting end 330 to the resin filling part 420 of the resin tank 400, and the second water channel connects the second connecting end 340 to the central tube 410 of the resin tank 400. In this embodiment, the two constructed water channels achieve communication with each resin tank 400, simplifying the structure of the water channel connection channel 303 and reducing the fabrication difficulty and manufacturing cost of the water channel component 300.

[0203] According to an embodiment of the present invention, a valve assembly 100 has a water inlet end, a water outlet end, and a water connection end. The water inlet end and the water outlet end are located on one side of the valve assembly 100, and the water connection end is located on the other side of the valve assembly 100. A transition assembly 200 is connected to the water connection end so that the transition assembly 200 communicates with each water passage within the valve assembly 100. The valve assembly 100 is typically used for water access and the output of treated water. The water inlet end is typically connected to the inlet pipe 112, and the water outlet end is connected to water-using equipment or water-using terminals. However, in typical household settings, installation space is limited, and ease of daily maintenance is required. In this embodiment, the water inlet end and the water outlet end are on the same side of the valve assembly 100, which facilitates the connection of the inlet and outlet water passages and allows for installation and disassembly within a limited space. Furthermore, placing the connection end on the other side spatially separates the inlet and outlet water passages from the connection end, which facilitates the connection layout of the valve assembly 100.

[0204] In a specific configuration, one side of the valve assembly 100 and the other side of the valve assembly 100 are positioned opposite each other. This allows one side of the valve assembly 100 to connect to the inlet pipe 112 and the outlet pipe 113, while the side opposite to the inlet pipe 112 and the outlet pipe 113 is connected to the adapter assembly 200. The water path through the valve assembly 100 is generally a straight line, which reduces the flow path of the water path and thus reduces the energy loss of the water path during the flow process.

[0205] According to an embodiment of the present invention, reference Figures 43-45 The valve assembly 100 is connected to an inlet pipe 112 and an outlet pipe 113. The inlet pipe 112 and the outlet pipe 113 extend along the length of the housing 10, and one end of the inlet pipe 112 and the outlet pipe 113 extends out of the rear cover plate 12 of the housing 10.

[0206] Understandably, in this embodiment, the valve assembly 100 is connected to the external water system via the inlet pipe 112 and the outlet pipe 113. That is, the inlet and outlet of the water softener are located at the rear cover plate 12 of the housing 10. Simultaneously, the valve assembly 100 can also be located near the rear cover plate 12 to reduce the length of the inlet pipe 112 and the outlet pipe 113, facilitating their arrangement and minimizing the space occupied by the water softener. This is particularly important for installation in environments with limited space, such as kitchens and bathrooms. By placing the inlet and outlet at the rear, space can be effectively saved, making it easier to integrate the water softener into existing layouts without requiring long pipes for water system connections.

[0207] In related technologies, the control of the valve assembly 100 of the water softener and the path control of the transfer assembly 200 require separate electrical control devices, which results in a complex and large-sized control system, increases the failure rate, and increases the difficulty and cost of maintenance.

[0208] According to an embodiment of the present invention, reference Figures 1-5 As shown, the valve assembly 100 includes a valve body 110, a valve core 140, a transmission mechanism 141, and a drive unit 142. The valve core 140 is connected to the drive unit 142 through the transmission mechanism 141. The transition assembly 200 is provided with a sewage discharge passage 2107 and a pressure rod. The drive unit 142 is adapted to drive the valve core 140 to rotate relative to the valve body 110 through the transmission mechanism 141 to realize the switching of different water passages. The transmission mechanism 141 is adapted to drive the pressure rod to switch between a sewage discharge position and a non-sewage discharge position. In the non-sewage discharge position, the pressure rod blocks the sewage discharge passage 2107. In the sewage discharge position, the pressure rod moves away to open the sewage discharge passage 2107.

[0209] It is understood that in this embodiment, the valve body 110 forms a valve cavity 111, an inlet channel 163, an outlet channel, a brine suction channel, and a backwash channel. The valve core 140 is rotatably disposed in the valve cavity 111. The drive unit 142 is connected to the valve core 140 through a rotation mechanism. When the drive unit 142 rotates, it drives the valve core 140 to rotate, so as to connect the valve cavity 111 with different water channels and realize the switching of different working states of the water softener. At the same time, the transmission mechanism 141 can also drive the pressure rod to switch between the sewage discharge position and the non-sewage discharge position during the movement, so as to realize the opening or closing of the sewage discharge channel 2107. That is, with only one drive unit 142, the switching of different water channels of the valve assembly 100 and the control of the opening and closing of the sewage discharge channel 2107 can be realized simultaneously. This simplifies the control logic, improves the control efficiency, reduces the number of control devices, reduces the size and space occupied by the water softener, and also reduces the failure rate of the water control components.

[0210] According to an embodiment of the present invention, reference Figures 1-5 As shown, the transmission mechanism 141 includes: a drive gear 1432, located at the output end of the drive unit 142; a driven gear 1431, meshing with the drive gear 1432, the driven gear 1431 having at least one drive block 1433, during the rotation of the transmission mechanism 141, the drive block 1433 being adapted to abut against and push the pressure rod to switch between the sewage discharge position and the non-sewage discharge position; and a rotating shaft 150 connected to the driven gear 1431; wherein the rotating shaft 150 is connected to the valve core 140 to drive the valve core 140 to control the water circuit switching.

[0211] like Figure 14 , Figure 22As shown, according to some embodiments of the present invention, the adapter assembly 200 includes a sewage control assembly 250, which is disposed in the sewage discharge passage 2107. The sewage control assembly 250 is used to control the opening and closing of the sewage discharge passage 2107. The transmission mechanism 141 includes a drive gear 1432, a driven gear 1431, and a rotating shaft 150. The drive gear 1432 is disposed at the output end of the drive unit 142. The driven gear 1431 meshes with the drive gear 1432. The driven gear 1431 has at least one drive block 1433, which is used to cooperate with the sewage control assembly 250 to open the sewage discharge passage 2107. The rotating shaft 150 is connected to the driven gear 1431. The rotating shaft 150 is connected to the valve core 140 to drive the valve core 140 to control the water circuit switching. The sewage control component 250 opens the sewage discharge path 2107 via a drive block 1433 on the driven gear 1431. Specifically, when the sewage discharge path 2107 needs to be opened, the rotation of the driven gear 1431 causes the drive block 1433 to press the sewage control component 250, thereby opening the sewage discharge path 2107. For example, at the brine suction position, the brine suction path is open, and the valve assembly 100 can transport the brine in the brine tank 500 to the resin tank 400. The brine is used to displace the calcium and magnesium ions adsorbed on the resin to reduce the resin, allowing it to continue adsorbing calcium and magnesium ions. The reduced wastewater enters the sewage discharge path 2107 through the transfer assembly 200. At this time, the drive block 1433 presses the sewage control component 250 to open the sewage discharge path 2107, enabling direct discharge of sewage. This achieves control of water path switching and sewage discharge path 2107 opening with a single drive unit 142, simplifying the control logic.

[0212] Hard water can have various impacts on daily life and household appliances. For example, it can reduce washing effectiveness, accumulate in water pipes causing reduced water flow, impair the performance and lifespan of appliances, and even cause skin problems. Therefore, people use water softeners to treat tap water in their daily lives. Water softeners effectively remove minerals from hard water, improving water quality and enhancing the quality of life. Typically, water softeners work by using ion exchange to remove calcium and magnesium ions from the water, thus transforming hard water into soft water.

[0213] One common method is using resin for treatment. This resin is a polymer with a special structure and a positively charged surface. When hard water passes through the resin particles, the calcium and magnesium ions in the resin adsorb onto the positively charged surface, replacing the original sodium ions. After a period of time, the resin particles gradually become saturated. At this point, brine is drawn in to clean the resin particles, regenerating them by replacing the adsorbed ions.

[0214] In related technologies, water circuit switching is achieved through control valves to realize the various functions of the water softener, while wastewater from resin particle cleaning is discharged through a separate sewage channel. In other words, the water circuit switching and sewage channel opening are controlled separately in these technologies. This increases the complexity of the control system, the number of components, and the manufacturing cost. Furthermore, the complex control system reduces the overall reliability of the equipment.

[0215] For issues related to the technology, see [link / reference]. Figure 1-5 As shown, the present invention provides a water softener, which includes a valve assembly 100, a transition assembly 200, a water circuit component 300, and a resin tank 400. The valve assembly 100 includes a valve body 110, a valve core 140, a drive unit 142, and a transmission mechanism 141. The valve core 140 and the drive unit 142 are both disposed within the valve body 110. The drive unit 142 is connected to the valve core via the transmission mechanism 141, so that the valve core 140 controls the water circuit switching under the drive of the drive unit 142. The transition assembly 200 and... A valve assembly 100 is connected and located on one side of the valve assembly 100. A transition assembly 200 has a wastewater discharge passage 2107 and cooperates with a transmission mechanism 141. A drive unit 142 is adapted to drive the transmission mechanism 141 to control the opening of the wastewater discharge passage 2107. A water circuit component 300 is connected to the transition assembly 200 and is used to guide the water flow. A resin tank 400 is fixedly connected to the water circuit component 300 and is used to soften the flowing water. When the water softener is in operation, the water flow direction in the resin tank 400 is different when different functions are required. The water flow direction is forward circulation if the water is input from the resin filling area at the top of the resin tank 400, rises through the central pipe 410, and is output. The water flow direction is reverse circulation if the water is input from the central pipe 410, rises through the resin particle filling area, and is output. In a water softener, the reverse circulation water path is typically output through the wastewater discharge path 2107. The wastewater discharge path 2107 is normally closed and opens when wastewater needs to be discharged. In this embodiment, through the cooperation of the drive unit 142 and the transmission mechanism 141, the switching of each water path can be controlled. Simultaneously, while controlling the switching of each water path, it can cooperate with the adapter component 200 to open the wastewater discharge path 2107. This enables the opening of each water path in the water softener and realizes all the functions of the water softener, simplifying the control system and improving its stability.

[0216] In specific settings, such as Figure 5As shown, the transmission mechanism 141 is connected to the drive unit 142. The drive unit 142 can drive the transmission mechanism 141 to rotate, and the rotation of the transmission mechanism 141 can drive the valve core 140 to rotate. When the valve core 140 rotates to different positions, it can switch between different water paths, thereby realizing different functions of the water softener. For example, the transmission mechanism 141 has corresponding mating parts. When the transmission mechanism 141 rotates or moves to a set position, the mating parts cooperate with the corresponding parts on the adapter assembly 200, thereby opening the sewage discharge path 2107. While the water softener realizes different functions, the transmission mechanism 141 can cooperate with the adapter assembly 200 to open the sewage discharge path 2107, thus realizing the realization of one drive unit 142 controlling different functional positions of the water softener.

[0217] Understandably, in related technologies, controlling the sewage discharge path 2107 often requires a separate control component and corresponding control module to open it, resulting in a large number of control components and a complex control system. In this example, the transmission component first controls the movement of the valve core 140, thereby switching between different water paths. During the switching process, the transmission mechanism 141 cooperates with the adapter component 200 to open the sewage discharge path 2107. In other words, the water path switching and control of the sewage discharge path 2107 are achieved through the cooperation of a drive unit 142 and the transmission mechanism 141, reducing the number of control components, simplifying the control system and control logic, and improving the stability of the control system.

[0218] In practical applications, raw water enters through valve assembly 100 and then flows into resin tank 400 through adapter assembly 200. Resin tank 400 is filled with resin particles and a central pipe 410. After being treated by the resin particles in resin tank 400, the raw water is output from valve assembly 100 after passing through adapter assembly 200. The flow direction of the water in resin tank 400 is controlled by adapter assembly 200. That is, the flow direction of the water in resin tank 400 is controlled by the transmission mechanism 141 in cooperation with adapter assembly 200, thereby controlling the forward and reverse circulation of water in resin tank 400.

[0219] like Figure 6 , Figure 7As shown, according to an embodiment of the present invention, the valve body 110 of the valve assembly 100 is provided with a valve cavity 111. The valve body 110 is also provided with an inlet pipe 112, an outlet pipe 113, an inlet tank pipe 114, and an outlet tank pipe 115, all of which are connected to the valve cavity 111. The valve cavity 111 has a valve seat 116. The valve core 140 is disposed on the valve seat 116 and located in the valve cavity 111. The valve core 140 switches between a service position, a brine suction position, a bypass position, a backwash position, and a water replenishment position relative to the valve seat 116, so that the valve core 140 and the valve seat 116 define a service water path, a brine suction water path, a bypass water path, a backwash water path, and a water replenishment water path. In this embodiment, when the water softener is operating, it mainly has a service position, a brine suction position, a bypass position, a backwash position, and a water replenishment position, and each position corresponds to a different water path. Different functions of the water softener are realized by controlling each water path.

[0220] In specific settings, the valve assembly 100 is used to control the flow direction of water (including raw water, softened water, wastewater, etc.) within the water softener to achieve the corresponding functions. For example... Figure 29 As shown, the water softener also includes a brine tank 500. As mentioned above, the resin tank 400 is filled with resin particles. These resin particles adsorb metal ions such as calcium and magnesium in the raw water to reduce its hardness. The resin tank 400 is connected to the valve assembly 100. The brine tank 500 contains brine and is also connected to the valve assembly 100. The brine tank 500 and the resin tank 400 are connected via the valve assembly 100. The brine tank 500 is adapted to supply brine to the resin tank 400 to clean and reduce the resin, allowing it to continue adsorbing calcium and magnesium ions. The valve assembly 100 is used to control the water flow. For example, the valve assembly 100 can control the flow of raw water into the resin tank 400 for filtration to reduce water hardness and form soft water.

[0221] It is understandable that, such as Figures 4-12 As shown, the inlet pipe 112 is adapted to connect to a water source to provide raw water; the outlet pipe 113 is adapted to connect to the user's end to provide water for the user; the tank inlet pipe 114 is adapted to connect to the inlet of the resin tank 400, and the tank outlet pipe 115 is adapted to connect to the outlet of the resin tank 400. In this embodiment of the water softener, at corresponding positions, the corresponding water path is switched to the connected state to deliver water to the corresponding position. Thus, by rotating the valve core 140 to the desired position, the corresponding water path is switched to the connected state, realizing the control of the water flow direction in the water softener, simplifying the control logic. Furthermore, the control of the water path in the water softener is realized through the valve assembly 100, improving the integration of the control structure of the water softener. In some embodiments, the cross-section of the valve cavity 111 is circular, the valve seat 116 is cylindrical, and the valve seat 116 is located at the center of the valve cavity 111.

[0222] At the service location, such as Figures 19-22As shown, at least the service water path is connected, and valve assembly 100 can deliver raw water to resin tank 400, whereby resin particles can adsorb calcium and magnesium ions from the raw water to produce soft water. At the brine suction point, as... Figures 25-29 As shown, at least the brine absorption path is in a connected state, and the valve assembly 100 can transport the brine in the brine tank 500 to the resin tank 400. The brine is used to displace the calcium and magnesium ions adsorbed on the resin, thereby reducing the resin and allowing it to continue adsorbing calcium and magnesium ions. At the bypass position, as... Figure 23 , Figure 24 As shown, at least the bypass water path is connected, and valve assembly 100 can directly deliver raw water to the user end. It is understandable that users have diverse water needs, and the required water hardness varies depending on the scenario.

[0223] For example, when flushing the toilet, the effect of water hardness can be ignored, and the user can use raw water for flushing. In this case, the valve core 140 is switched to the bypass position to provide raw water for flushing the toilet. This reduces the resin filtration process, thereby reducing resin consumption. In the backwash position, such as... Figures 31-34 As shown, at least the backwash water path is in a connected state. At this time, the valve assembly 100 delivers water to the resin tank 400 to flush the resin, remove broken resin, and increase the gaps between resin particles. This allows the resin to fully contact the raw water after switching to the service position, adsorbing calcium and magnesium ions and improving the filtration effect. At the water replenishment position, at least the water replenishment path is in a connected state, and the valve assembly 100 is adapted to deliver water to the brine tank 500 to replenish the brine.

[0224] It is understood that in this embodiment, the valve core 140 is driven to rotate by the drive unit 142 to switch between the service position, the brine suction position, the bypass position, the backwash position and the water replenishment position. The valve core 140 and the valve seat 116 define the corresponding water path to control the flow direction of water in the water softener, which simplifies the control logic and reduces operating costs.

[0225] like Figure 6 , Figure 7As shown, according to some embodiments provided by the present invention, the outer peripheral wall of the valve seat 116 and the inner peripheral wall of the valve cavity 111 define a first water inlet cavity 130. The valve seat 116 has a spaced-apart tank inlet cavity 131 and a second water inlet cavity 132. The tank inlet cavity 131 is connected to the tank inlet pipe 114. The water inlet pipe 112 is connected to both the first water inlet cavity 130 and the second water inlet cavity 132. The valve seat 116 is provided with a bypass cavity 133, which is connected to the water outlet pipe 113 and is spaced apart from the second water inlet cavity 132. The tank inlet cavity 131 is connected to either the first water inlet cavity 130 or the second water inlet cavity 132 through the valve core 140. The first water inlet cavity 130, the second water inlet cavity 132, the valve core 140, and the tank inlet cavity 131 together define a service water path. Raw water is transported through inlet pipe 112 to the first inlet chamber 130 and the second inlet chamber 132, flows through valve core 140 to tank inlet chamber 131, and is transported through inlet pipe 114 to the inlet of resin tank 400.

[0226] The bypass chamber 133 is connected to either the first inlet chamber 130 or the second inlet chamber 132 via the valve core 140. The first inlet chamber 130, the second inlet chamber 132, the valve core 140, and the bypass chamber 133 together define the bypass water path. Raw water is delivered to the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112, flows to the bypass chamber 133 through the valve core 140, and finally flows out through the outlet pipe 113 to be provided to the user. In this way, raw water can be delivered to the resin tank 400 for filtration to provide soft water through the service water path, or raw water can be provided to the user through the bypass water path, which improves the flexibility of the water softener.

[0227] According to some embodiments of the present invention, the water outlet pipe 113 and the tank outlet pipe 115 are connected by a bypass check valve 137 to allow unidirectional flow from the tank outlet pipe 115 to the water outlet pipe 113. Figure 5 and Figure 23 As shown, the valve assembly 100 also includes a bypass check valve 137. The outlet pipe 113 is connected to the tank outlet pipe 115. Soft water produced by the resin tank 400 flows through the tank outlet pipe 115 to the outlet pipe 113, and is then delivered to the user. Thus, the water flowing in the outlet pipe 113 includes the soft water produced in the resin tank 400 and the raw water flowing out through the bypass cavity 133. The bypass check valve 137 can be located in the outlet pipe 113 or the tank outlet pipe 115. The bypass check valve 137 is unidirectional, allowing water to flow unidirectionally from the tank outlet pipe 115 to the outlet pipe 113, preventing backflow of water from the outlet pipe 113 into the resin tank 400. The bypass cavity 133 is connected to the outlet pipe 113 at a point between the bypass check valve 137 and the outlet of the outlet pipe 113, to prevent the raw water in the bypass cavity 133 from flowing to the tank outlet pipe 115. Figure 5 and Figure 23As shown, in some embodiments, the valve assembly 100 further includes a flow meter 183, which is disposed within the outlet pipe 113 and closer to the outlet of the outlet pipe 113 than the location where the bypass cavity 133 communicates with the outlet pipe 113. The flow meter 183 is used to detect the water flow rate output from the outlet pipe 113. Figure 23 As shown, the flow meter 183 is inserted into the outlet pipe 113 and is fixedly connected to the outlet pipe 113 by insertion.

[0228] like Figure 14 , Figure 22 As shown, according to some embodiments of the present invention, the adapter assembly 200 includes a sewage control assembly 250, which is disposed in the sewage discharge passage 2107. The sewage control assembly 250 is used to control the opening and closing of the sewage discharge passage 2107. The transmission mechanism 141 includes a drive gear 1432, a driven gear 1431, and a rotating shaft 150. The drive gear 1432 is disposed at the output end of the drive unit 142. The driven gear 1431 meshes with the drive gear 1432. The driven gear 1431 has at least one drive block 1433, which is used to cooperate with the sewage control assembly 250 to open the sewage discharge passage 2107. The rotating shaft 150 is connected to the driven gear 1431. The rotating shaft 150 is connected to the valve core 140 to drive the valve core 140 to control the water circuit switching. The sewage control component 250 opens the sewage discharge path 2107 via a drive block 1433 on the driven gear 1431. Specifically, when the sewage discharge path 2107 needs to be opened, the rotation of the driven gear 1431 causes the drive block 1433 to press the sewage control component 250, thereby opening the sewage discharge path 2107. For example, at the brine suction position, the brine suction path is open, and the valve assembly 100 can transport the brine in the brine tank 500 to the resin tank 400. The brine is used to displace the calcium and magnesium ions adsorbed on the resin to reduce the resin, allowing it to continue adsorbing calcium and magnesium ions. The reduced wastewater enters the sewage discharge path 2107 through the transfer assembly 200. At this time, the drive block 1433 presses the sewage control component 250 to open the sewage discharge path 2107, enabling direct discharge of sewage. This achieves control of water path switching and sewage discharge path 2107 opening with a single drive unit 142, simplifying the control logic.

[0229] In specific settings, such as Figure 5As shown, the drive unit 142 is a drive motor, which is fixedly connected to the valve body 110. The drive motor can be fixedly connected to the valve body 110 by screws. The driven gear 1431 is larger than the drive gear 1432. The two gears mesh, and the drive motor drives the drive gear 1432 to rotate. The drive gear 1432 drives the driven gear 1431 to rotate, and the driven gear 1431 drives the rotating shaft 150 to rotate, which in turn drives the moving plate 160 inside the valve core 140 to rotate. The transmission ratio between the drive gear 1432 and the transmission gear is greater than 1, that is, the number of teeth of the drive gear 1432 is greater than the number of teeth of the transmission gear, so as to amplify the driving torque and provide sufficient power to drive the rotating shaft 150 and the moving plate 160 to rotate.

[0230] like Figure 5 , Figure 11 and Figure 12 As shown, according to some embodiments of the present invention, the valve core 140 includes a movable piece 160, which is fixedly connected to a rotating shaft 150. The rotating shaft 150 drives the movable piece 160 to rotate. The movable piece 160 is disposed on a valve seat 116, and the movable piece 160 cooperates with the valve seat 116 to define a service water path, a brine intake path, a bypass water path, a backwash water path, and a makeup water path. The drive unit 142 is connected to the valve body 110, and the rotating shaft 150 is rotatably connected to the valve body 110. The rotating shaft 150 is drively connected to the drive unit 142, and the movable piece 160 is fixedly connected to the rotating shaft 150. The rotating shaft 150 drives the movable piece 160 to rotate. The movable piece 160 is adapted to be attached to the top of the valve seat 116. The rotating shaft 150 is driven to rotate by the drive assembly, and the rotating shaft 150 drives the movable piece 160 to rotate, so that the movable piece 160 cooperates with the valve seat 116 to define the corresponding water path. For example, rotating the movable plate 160 causes it to engage with the inlet chamber 131. Thus, the first inlet chamber 130, the second inlet chamber 132, the movable plate 160, and the inlet chamber 131 together define the service water path.

[0231] like Figure 5 As shown, according to some embodiments of the present invention, the valve body 110 includes a valve body portion and a valve plug 118. A valve cavity 111 is disposed within the valve body portion, and one side of the valve cavity 111 is open. A rotating shaft 150 passes through the valve cavity 111, with one end of the rotating shaft 150 located inside the valve cavity 111 and the other end located outside the valve cavity 111. A gear assembly 143 and a drive motor are both located outside the valve cavity 111. The gear assembly 143 is formed by the meshing of a drive gear 1432 and a transmission gear, and the drive motor is a drive unit 142. The valve plug 118 covers the open end of the valve cavity 111 to seal the valve cavity 111. The rotating shaft 150 passes through the valve plug 118, and the gear assembly 143 is located outside the valve cavity 111. Figure 6As shown, the valve body is provided with a receiving groove 117, and the drive motor is adapted to be received in the receiving groove 117. The valve plug 118 is adapted to cover the receiving groove 117, and the output shaft of the drive motor passes through the valve plug 118. One end of the drive motor abuts against and is fixedly connected to the valve plug 118.

[0232] like Figure 5 As shown, according to some embodiments of the present invention, the rotating shaft 150 includes a vertical shaft 151 and a connecting disc 152. One end of the vertical shaft 151 is connected to a drive assembly, and the vertical shaft 151 passes through the valve cavity 111. One end of the vertical shaft 151 is fixedly connected to the driven gear 1431. The connecting disc 152 is disposed at the other end of the vertical shaft 151. The connecting disc 152 is stacked and fixedly connected to the moving plate 160. The connecting disc 152 is disc-shaped to adapt to the moving plate 160, and the diameter of the connecting disc 152 can be less than or equal to the diameter of the moving plate 160. In some embodiments, a pressure block is provided on the side facing the valve plug 118. The pressure block is located inside the valve cavity 111 and abuts against the connecting disc 152 to limit the rotation shaft 150 in the axial direction.

[0233] like Figure 5 and Figure 11 As shown, according to some embodiments of the present invention, the connecting disc 152 is provided with a first engaging portion 153, and the movable piece 160 is provided with a second engaging portion 167 that cooperates with the first engaging portion 153. One of the first engaging portion 153 and the second engaging portion 167 is a groove, and the other is a protrusion. The first engaging portion and the second engaging portion cooperate to circumferentially limit the movable piece 160, so that the rotating shaft 150 can drive the movable piece 160 to rotate.

[0234] There can be multiple first and second clips / parts. Multiple first clips / parts are spaced apart along the circumferential direction of the connecting disc 152, and multiple second clips / parts are spaced apart along the circumferential direction of the movable piece 160. Each of the multiple first clips / parts includes a first positioning part, and each of the multiple second clips / parts includes a second positioning part. The first positioning part and the second positioning part are adapted to position the relative positions of the movable piece 160 and the connecting disc 152 in the circumferential direction, preventing misalignment of the rotating shaft 150 and the movable piece 160 during assembly. For example, as... Figure 11 As shown, there are four second clips / parts, three of which are grooves and one is a protrusion. There are also four first clips / parts, three of which are protrusions and one is a groove. The grooved first clips / parts and the protruding second clips / parts are fitted together to circumferentially position the moving piece 160 and the connecting plate 152, ensuring that their relative positions in the circumferential direction are uniquely determined for assembly.

[0235] See Figure 5As shown, according to some embodiments of the present invention, the valve body 110 further includes a control plate 119, which is fixed relative to the valve seat 116 and can be fixedly connected to the valve plug 118. The control plate 119 is sleeved on the rotating shaft 150 and is located between the valve plug 118 and the gear assembly 143. A Hall sensor 1191 is provided on the control plate 119, and a magnetic element is provided on the gear assembly 143. The Hall sensor 1191 is used to sense the position of the magnetic element. Thus, the drive motor can be controlled according to the position of the magnetic element detected by the Hall sensor 1191, thereby controlling the rotation angle of the moving plate 160 so that the moving plate 160 rotates to the corresponding position.

[0236] like Figure 5 As shown, in some embodiments, there can be multiple Hall sensors 1191, which are spaced apart along the circumferential direction of the rotation axis 150. The positions of the multiple Hall sensors 1191 correspond to the service position, brine suction position, bypass position, backwash position, and water replenishment position, respectively. When the magnetic component moves to the position closest to one of the Hall sensors 1191, the valve core 140 switches to the corresponding position. For example, one of the multiple Hall sensors 1191 may correspond to the service position; when the magnetic component moves to the position closest to that Hall sensor 1191, the valve core 140 switches to the service position. The orthographic projection of the movement trajectory of each Hall sensor 1191 and the magnetic component on the control board 119 can coincide to improve the detection accuracy of the Hall sensors 1191. When the valve core 140 switches to the service position, the magnetic component is opposite the corresponding Hall sensor 1191. See also... Figure 5 As shown, the valve assembly 100 also includes a top cover 101, which covers the valve body 110 and is fixedly connected to it. The top cover 101 serves to seal and protect the valve body 110. An installation space is defined between the top cover 101 and the valve body 110. The open end of the valve seat 116 is located within the installation space, and the drive assembly and control board 119 are both housed within the installation space.

[0237] like Figure 5 , Figure 8 and Figure 9 As shown, according to some embodiments of the present invention, the valve core 140 further includes a fixed plate 170, which is attached to the valve seat 116 and sandwiched between the movable plate 160 and the valve seat 116. The fixed plate 170 is fixed relative to the valve seat 116, while the movable plate 160 is rotatable relative to the fixed plate 170. The fixed plate 170 can space the movable plate 160 from the valve seat 116, preventing wear on the valve seat 116 during rotation and extending the service life of the valve body 110. Furthermore, the fixed plate 170 is easily replaceable, facilitating later maintenance. Figure 8As shown, the fixed plate 170 is provided with a fixed bypass hole 171 corresponding to and communicating with the bypass cavity 133. The movable plate 160 cooperates with the fixed plate 170 and the valve seat 116 to define the service water path, the brine intake path, the bypass water path, the backwash water path, and the makeup water path. Specifically, the first water inlet cavity 130, the second water inlet cavity 132, the movable bypass hole 162, the fixed bypass hole 171, and the bypass cavity 133 together define the bypass water path. The fixed plate 170 is also provided with a fixed water inlet hole 173 and a fixed tank inlet hole 174. The fixed water inlet hole 173 communicates with the second water inlet cavity 132, and the fixed tank inlet hole 174 communicates with the tank inlet cavity 131.

[0238] like Figure 5 and Figure 10 As shown, in some embodiments, a sealing gasket 180 is provided between the fixed plate 170 and the valve seat 116. The shape of the sealing gasket 180 is the same as that of the fixed plate 170, or the shape of the sealing gasket 180 is the same as that of the top surface of the valve seat 116, so that the fixed plate 170 and the valve seat 116 can be sealed to prevent water leakage, and can also be fixed relative to the valve seat 116 to prevent the fixed plate 170 from sliding with the moving plate 160. The sealing gasket 180 can be a rubber part, and the sealing gasket 180 can undergo a certain deformation to fit tightly with the valve seat 116 and the fixed plate 170 to avoid water leakage.

[0239] like Figure 6 and Figure 9 As shown, according to some embodiments of the present invention, the inner wall of the valve cavity 111 is provided with a first fixing part 1111, and the periphery of the fixing piece 170 is provided with a second fixing part 172. The second fixing part 172 engages with the first fixing part 1111 to position the fixing piece 170 circumferentially and prevent the fixing piece 170 from rotating relative to the valve seat 116. One of the second fixing part 172 and the first fixing part 1111 is a groove, and the other is a protrusion. Figure 6 and Figure 9 In the example, the first fixing part 1111 is a protrusion, and the second fixing part 172 is a groove.

[0240] In some embodiments, there are multiple first fixing portions 1111 and multiple second fixing portions 172. The multiple first fixing portions 1111 are spaced apart along the circumferential direction of the valve cavity 111, and the multiple second fixing portions 172 are spaced apart along the circumferential direction of the fixing plate 170. Among the multiple first fixing portions 1111, there is one first fixing portion 1111 with a width different from the other first fixing portions 1111. Among the multiple second fixing portions 172, there is one second fixing portion 172 with a width different from the other second fixing portions 172. The first fixing portion 1111 and the second fixing portion 172 cooperate to position the relative position of the fixing plate 170 and the valve seat 116 in the circumferential direction, thereby preventing the fixing plate 170 from being misaligned with the valve seat 116 during installation, which would result in a failure to seal.

[0241] For example, such as Figure 6 As shown, there are three first fixing parts 1111, all of which are protrusions, as... Figure 9 As shown, there are three second fixing parts 172, all of which are protrusions. One of the first fixing parts 1111 has a wider circumferential width than the other two, and one of the second fixing parts 172 has a wider circumferential width than the other two. The first fixing part 1111 and the second fixing part 172 cooperate to position the relative positions of the fixing plate 170 and the valve seat 116 in the circumferential direction. This facilitates the installation of the fixing plate 170, prevents misalignment of the fixing plate 170 leading to poor sealing, and prevents water leakage from the valve seat 116.

[0242] See Figure 11 and Figure 12 As shown, according to some embodiments of the present invention, the movable plate 160 is provided with spaced-apart movable inlet holes 161 and movable bypass holes 162. In the service position, the first inlet chamber 130 and the second inlet chamber 132 are connected to the inlet tank chamber 131 through the movable inlet holes 161, and the first inlet chamber 130, the second inlet chamber 132, the movable inlet holes 161, and the inlet tank chamber 131 define a service water path. At this time, raw water is transported to the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112, and the raw water in the first inlet chamber 130 and the second inlet chamber 132 flows to the inlet tank chamber 131 through the movable inlet holes 161. The raw water in the inlet tank chamber 131 is transported to the inlet of the resin tank 400 through the inlet pipe 114. The raw water contacts the resin to reduce the concentration of calcium and magnesium ions, forming soft water. Soft water flows from the outlet of resin tank 400 into outlet pipe 115, and then flows unidirectionally through outlet pipe 115 to outlet pipe 113, and finally is delivered to the user end through the pipeline.

[0243] In the bypass position, the first inlet chamber 130 and the second inlet chamber 132 are connected to the bypass chamber 133 through the movable bypass hole 162. The first inlet chamber 130, the second inlet chamber 132, the movable bypass hole 162, and the bypass chamber 133 define a bypass water path. Raw water is transported to the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112. The raw water in the first inlet chamber 130 and the second inlet chamber 132 flows into the bypass chamber 133 through the movable bypass hole 162. The raw water in the bypass chamber 133 flows out through the outlet pipe 113 and is transported to the user end through a pipeline. Figure 6 As shown, the inlet chamber 131 and the bypass chamber 133 are spaced apart along the circumferential direction of the valve seat 116, and the moving water inlet hole 161 and the moving bypass hole 162 are spaced apart along the circumferential direction of the moving plate 160. By rotating the moving plate 160, the moving water inlet hole 161 can be switched to be connected to or not connected to the inlet chamber 131, and the moving bypass hole 162 can be switched to be connected to or not connected to the bypass chamber 133.

[0244] See Figure 11 As shown, according to some embodiments of the present invention, the surface of the movable piece 160 facing away from the valve seat 116 is provided with a water inlet channel 163. The water inlet channel 163 connects the movable water inlet hole 161 and the first water inlet chamber 130 to guide water in the first water inlet chamber 130 into the movable water inlet hole 161. In some embodiments, the surface of the movable piece 160 facing away from the valve seat 116 is also provided with a connecting port 164, which connects the water inlet channel 163 and the first water inlet chamber 130. The connecting port 164 is located at the edge of the movable piece 160 and extends radially along the movable piece 160. There are multiple connecting ports 164 connecting the water inlet channel 163 and the first water inlet chamber 130, and the multiple connecting ports 164 are distributed at intervals along the circumferential direction of the movable piece 160. Some of the connecting ports 164 are connected to the movable water inlet hole 161 or the movable bypass hole 162, and water in the first water inlet chamber 130 can flow to the movable water inlet hole 161 and the movable bypass hole 162 from multiple directions. Multiple connecting ports 164 can be evenly distributed along the circumferential direction of the moving plate 160 to uniformly guide water into the moving inlet port 161 and the moving bypass port 162. Thus, when the connecting plate 152 and the moving plate 160 are connected, water in the first inlet chamber 130 can flow through the inlet channel 163 and connecting ports 164 to the moving inlet port 161 and the moving bypass port 162, and then to the inlet chamber 131 and the bypass chamber 133. When water flows within the inlet channel 163 and connecting ports 164, the water exerts pressure on the moving plate 160, causing the moving plate 160 to fit tightly against the valve seat 116, which simplifies the fixing structure of the moving plate 160. Figure 11 As shown, the water inlet channel 163 can extend in an arc shape, that is, the water inlet channel 163 is arc-shaped. One end of the arc-shaped water inlet channel 163 is connected to the moving water inlet hole 161, and the other end is connected to the moving bypass hole 162.

[0245] like Figures 19-22 As shown, where Figure 19 This is a schematic diagram of the valve assembly 100 when the valve core 140 is in the service position. Figure 20 This is a schematic diagram showing the relative positions of the moving plate 160 and the fixed plate 170 when the valve core 140 is in the service position. Figure 21 This is another schematic diagram showing the relative positions of the moving plate 160 and the stationary plate 170 when the valve core 140 is in the service position. Figure 22 This is a cross-sectional view of the water softener when valve core 140 is in the service position. The arrows in the figure indicate the direction of water flow.

[0246] When the valve core 140 is in the service position, the first inlet chamber 130, the second inlet chamber 132, the connecting port 164, the inlet channel 163, the movable inlet hole 161, the fixed inlet port 174, and the inlet chamber 131 together define the service water path. The movable inlet hole 161 communicates with the inlet chamber 131 through the fixed inlet port 174, and with the first inlet chamber 130 through the inlet channel 163 and the connecting port 164. The movable bypass hole 162 communicates with the second inlet chamber 132 through the fixed inlet hole 173. Thus, raw water is transported to the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112. Raw water in the first inlet chamber 130 can flow into the inlet channel 163 through the connecting port 164 (e.g., ...). Figure 19 and Figure 20 The flow direction indicated by the middle arrow 1) then flows into the moving water inlet 161 (as shown by the middle arrow 1). Figure 19 and Figure 20 (Flow direction indicated by arrow 2). Raw water in the second inlet chamber 132 can flow into the inlet channel 163 through the fixed inlet hole 173 and the moving bypass hole 162, and then into the moving inlet hole 161. After flowing into the moving inlet hole 161, the raw water flows into the inlet chamber 131 through the fixed inlet hole 174. The raw water in the inlet chamber 131 is then transported to the inlet of the resin tank 400 through the inlet pipe 114.

[0247] like Figure 22 As shown, the inlet and outlet of the resin tank 400 are both located at one end of the resin tank 400. A central pipe 410 is installed inside the resin tank 400. One end of the central pipe 410 is connected to the outlet of the resin tank 400, and the other end is connected to the resin tank 400. Resin is contained within the resin tank 400 and located outside the central pipe 410. Raw water enters the resin tank 400 from the inlet (e.g.,...). Figure 22 (Flow direction indicated by arrow 2) and comes into contact with the resin. The resin adsorbs calcium and magnesium ions in the raw water, forming soft water. The soft water reaches the other end of the resin tank 400, flows from the central pipe 410 to the outlet of the resin tank 400, and flows through the outlet pipe 115 and the bypass check valve 137 to the outlet pipe 113. The soft water output from the outlet pipe 113 is transported to the user end through pipelines.

[0248] like Figure 23 and Figure 24 As shown, where, Figure 24This is a cross-sectional view of the water softener when the valve core 140 is in the bypass position. The arrows in the figure indicate the direction of water flow. In the bypass position, the first inlet chamber 130, the second inlet chamber 132, the connecting port 164, the inlet channel 163, the movable bypass hole 162, the fixed bypass hole 171, and the bypass chamber 133 together define the bypass water path. The movable bypass hole 162 communicates with the bypass chamber 133 through the fixed bypass hole 171. The movable bypass hole 162 communicates with the first inlet chamber 130 through the inlet channel 163 and the connecting port 164. The movable inlet hole 161 communicates with the second inlet chamber 132 through the fixed inlet hole 173. Raw water is transported through inlet pipe 112 to the first inlet chamber 130 and the second inlet chamber 132. Raw water in the first inlet chamber 130 flows into the moving bypass hole 162 through the connecting port 164 and the inlet channel 163. Raw water in the second inlet chamber 132 flows into the moving bypass hole 162 through the fixed inlet hole 173, the moving inlet hole 161, and the inlet channel 163. Raw water flowing into the moving bypass hole 162 flows into the bypass chamber 133 through the fixed bypass hole 171. Raw water in the bypass chamber 133 flows out from the outlet pipe 113 and is transported to the user's end through a pipeline. Figure 24 As shown, the raw water does not pass through the resin tank 400 during this process. This allows for flexible water supply based on user needs during use and reduces resin consumption.

[0249] See Figure 6 As shown, according to some embodiments of the present invention, the valve seat 116 is provided with a spaced-apart salt suction chamber 134 and a salt suction connecting chamber 135, the salt suction chamber 134 being adapted to communicate with the salt tank 500. For example... Figure 12 As shown, the movable plate 160 is provided with a movable brine suction and water distribution hole 165, which is a blind hole 168, and is located on the surface of the movable plate 160 facing the valve seat 116. The brine suction communication cavity 135 is adapted to communicate with the movable brine suction and water distribution hole 165. The movable water inlet hole 161 extends through the movable plate 160 along its thickness direction, and the movable brine suction and water distribution hole 165 is spaced apart from the movable water inlet hole 161. At the brine suction position, the movable inlet 161 is connected to the movable brine suction distribution port 165 via the brine suction connecting chamber 135. The movable brine suction distribution port 165 is connected to the brine suction chamber 134 and the bypass chamber 133 respectively. The movable inlet 161, the brine suction connecting chamber 135, the movable brine suction distribution port 165, and the brine suction chamber 134 define the brine suction path, and the movable inlet 161, the brine suction connecting chamber 135, the movable brine suction distribution port 165, and the bypass chamber 133 define the bypass water path. In this way, at the brine suction position, raw water can be supplied to the user through the bypass water path.

[0250] like Figure 6 and Figure 12As shown, the brine suction connecting cavity 135 extends radially along the valve seat 116, with one end of the brine suction connecting cavity 135 located at the center of the valve seat 116; the movable brine suction water distribution hole 165 extends radially along the movable plate 160, with one end of the movable brine suction water distribution hole 165 located at the center of the movable plate 160. Thus, during the rotation of the movable plate 160, one end of the brine suction connecting cavity 135 remains in communication with one end of the movable brine suction water distribution hole 165. The brine suction connecting cavity 135 and the movable brine suction water distribution hole 165 can function to connect the through hole on the movable plate 160 with the chamber on the valve seat 116.

[0251] See Figures 25 to 29 As shown in the figure, valve cores 140 are all located at the salt suction position. Among them, Figure 25 This is a structural schematic diagram of valve assembly 100; Figure 26 This is a schematic diagram of the internal structure of valve chamber 111, where the moving plate 160 and the fixed plate 170 are not shown. The arrows in the figure indicate the direction of water flow. Figure 27 This is a schematic diagram showing the relative positions of the moving plate 160 and the fixed plate 170; Figure 28 This is another perspective view of the relative positions of the moving plate 160 and the fixed plate 170. The arrows in the figure indicate the direction of water flow. Figure 29 This is a cross-sectional view of a water softener. The arrows in the diagram indicate the direction of water flow.

[0252] At the brine suction position, the moving water inlet 161 is connected to the brine suction connecting cavity 135 through the fixed brine suction connecting hole 176 on the fixed plate 170. The brine suction connecting cavity 135 is connected to the moving brine suction water distribution hole 165 through the fixed brine suction connecting hole 176. The moving brine suction water distribution hole 165 is connected to the bypass cavity 133 through the fixed bypass hole 171. The moving brine suction water distribution hole 165 is connected to the brine suction cavity 134 through the fixed brine suction hole 175. The moving bypass hole 162 is connected to the second water inlet cavity 132 through the moving fixed water inlet hole 173.

[0253] Raw water is introduced into the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112. Raw water in the first inlet chamber 130 flows to the moving inlet hole 161 through the connecting port 164 and the inlet channel 163. Raw water in the second inlet chamber 132 flows to the moving inlet hole 161 through the fixed inlet hole 173, the moving bypass hole 162, and the inlet channel 163. Raw water in the moving inlet hole 161 flows into the brine suction connecting chamber 135 (e.g., through the fixed brine suction connecting hole 176) through the fixed brine suction connecting hole 176. Figure 27 and Figure 28 (Flow direction indicated by arrow 1). The raw water in the brine suction connecting chamber 135 flows into the moving brine suction and water distribution hole 165. In the moving brine suction and water distribution hole 165, a portion of the raw water flows into the brine suction chamber 134 through the fixed brine suction hole 175 (e.g., ...). Figure 28(Flow direction indicated by arrow 2); another part of the raw water flows into the bypass cavity 133 through the fixed bypass hole 171, and the raw water in the bypass cavity 133 is output through the outlet pipe 113 to be provided to the user.

[0254] According to some embodiments of the present invention, the salt suction chamber 134 is selectively connected to the salt tank 500. In the salt suction position: the salt suction chamber 134 is connected to the salt tank 500, the valve assembly 100 is in the salt suction mode, and the brine in the salt tank 500 and the raw water in the salt suction chamber 134 are transported to the resin tank 400 to clean and restore the resin, thereby restoring its adsorption capacity; when the salt suction chamber 134 is disconnected from the salt tank 500, the valve assembly 100 is in the slow wash mode, at which time the salt tank 500 stops supplying brine, and the raw water in the salt suction chamber 134 is transported to the resin tank 400 to rinse the resin tank 400, thereby washing away the salt in the resin. Figure 7 As shown, in some embodiments, the valve assembly 100 further includes a jet pipe 181, which contains an ejector 240. The jet pipe 181 is connected to the valve body 110 and communicates with the brine suction chamber 134. The jet pipe 181 is connected to both the brine tank 500 and the resin tank 400. When the brine suction chamber 134 is connected to the brine tank 500, the ejector 240 can transport the water in the brine suction chamber 134 and the brine in the brine tank 500 to the resin tank 400. When the brine suction chamber 134 is disconnected from the brine tank 500, the jet pipe 181 can transport the water in the brine suction chamber 134 to the resin tank 400 to rinse the resin.

[0255] See Figure 29 As shown, according to some embodiments of the present invention, the valve assembly 100 further includes a wastewater discharge passage 2107, which is selectively connected to the inlet pipe 114, which is connected to the inlet of the resin tank 400, thereby connecting the wastewater discharge passage 2107 to the resin tank 400 via the inlet pipe 114. In the brine suction position, the wastewater discharge passage 2107 is connected to the inlet pipe 114. Wastewater generated during resin cleaning in the brine suction mode and slow wash mode can be discharged through the wastewater discharge passage 2107. In some embodiments, the adapter assembly 200 includes a wastewater control assembly 250, which controls the connection and disconnection of the wastewater discharge passage 2107 and the inlet pipe 114. In specific examples, such as... Figure 29 As shown, the sewage control component 250 is located at the connection between the sewage discharge passage 2107 and the tank inlet pipe 114, and a drive block 1433 is provided on the bottom surface of the driven gear 1431. When the valve core 140 is in the salt suction position, the drive block 1433 pushes the pressure rod to move, so that the sewage discharge passage 2107 is connected to the tank inlet pipe 114.

[0256] like Figure 29As shown, the jet pipe 181 is connected to the central pipe 410 of the resin tank 400. When the valve assembly 100 is in the brine suction mode, the lever is in the open state. A portion of the raw water entering the valve assembly 100 is delivered to the jet pipe 181 through the brine suction circuit (e.g., Figure 29 (As indicated by arrow 2), the jet pipe 181 mixes the brine and raw water and delivers them to the outlet of the resin tank 400. The mixed brine flows through the central pipe 410 to the other end of the resin tank 400 and contacts the resin, thereby displacing the calcium and magnesium ions adsorbed on the resin and restoring its adsorption capacity. The mixed brine after cleaning the resin flows out from the inlet of the resin tank 400 and is discharged from the wastewater drain 2107. Another portion of the raw water from the input valve assembly 100 is delivered to the outlet pipe 113 (e.g., ...) through the bypass water path. Figure 29 (The flow direction indicated by arrow 3) is provided to the user. Figure 30 As shown, in slow wash mode, the flow direction of the raw water is the same as that in the brine absorption mode described above, except that the brine tank 500 does not provide brine, which will not be described further here. At the brine absorption position, the valve assembly 100 provides water through the brine absorption path and the bypass water path. In this way, water can be provided to the user simultaneously while the resin is being cleaned and restored, achieving uninterrupted water supply and avoiding affecting the user's water usage.

[0257] like Figure 6 and Figure 12 As shown, according to some embodiments of the present invention, the moving plate 160 is provided with a moving backwash hole 166 extending along its thickness direction, the seat body is provided with a backwash chamber 136, the valve body 110 is provided with a backwash pipe 182, the backwash pipe 182 communicates with the backwash chamber 136, and the backwash pipe 182 communicates with the central pipe 410 of the resin tank 400. Figure 6 In the example, the backwash chamber 136 and the brine suction chamber 134 are spaced apart in the radial direction of the valve seat 116. Figure 12 In the example, the moving water inlet 161, the moving backwash hole 166, and the moving bypass hole 162 are distributed sequentially at intervals in the circumferential direction of the moving plate 160.

[0258] In the backwash position, the backwash chamber 136 is connected to the movable bypass hole 162 to define the backwash water path; the movable backwash hole 166 is connected to the bypass chamber 133 to define the bypass water path. In the backwash position, a portion of the raw water from the input valve assembly 100 is transported to the resin tank 400 through the backwash water path and backwash pipe 182 to backwash the resin, flushing away broken resin and increasing the gaps between resin particles. This ensures that the resin particles are in full contact with the raw water in the service position, improving the adsorption effect on calcium and magnesium ions in the raw water. The other portion of the raw water from the input valve assembly 100 is output through the bypass water path and outlet pipe 113 to provide water to the user, achieving uninterrupted water supply. When the valve core 140 is in the backwash position, the wastewater discharge path 2107 is connected to the resin tank 400 to discharge the wastewater generated during the backwash process.

[0259] like Figures 31 to 34 As shown, valve cores 140 are all in the backwash position at this time, and the arrows in the figure indicate the direction of water flow. Figure 31 This is a structural schematic diagram of valve assembly 100; Figure 32 This is a schematic diagram showing the relative positions of the moving plate 160 and the fixed plate 170; Figure 33 Another perspective diagram showing the relative positions of the moving plate 160 and the fixed plate 170; Figure 34 This is a cross-sectional view of a water softener.

[0260] In the backwash position, valve core 140 and valve seat 116 define the backwash water path and the bypass water path. The movable bypass port 162 communicates with the backwash chamber 136 through the fixed backwash port 177, the movable backwash port 166 communicates with the bypass chamber 133 through the fixed bypass port 171, and the movable inlet port 161 communicates with the second inlet chamber 132 through the fixed inlet port 173. Raw water is transported to the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112 (e.g., ...). Figure 34 (Flow direction indicated by arrow 1). Raw water in the first inlet chamber 130 flows through the connecting port 164 and the inlet channel 163 to the moving bypass hole 162 and the moving backwash hole 166. Raw water in the second inlet chamber 132 flows through the fixed inlet hole 173, the moving inlet hole 161 and the inlet channel 163 to the moving bypass hole 162 and the moving backwash hole 166.

[0261] Raw water flowing to the bypass hole 162 flows into the backwash chamber 136 through the fixed backwash hole 177 (e.g.) Figure 34(Flow direction indicated by arrow 2) thus flows through backwash pipe 182 into the central pipe 410 of resin tank 400. Raw water is delivered through central pipe 410 to the other end of resin tank 400 to rinse the resin. At the backwash position, wastewater discharge path 2107 is connected to inlet pipe 114 of resin tank 400. Wastewater generated after rinsing the resin with raw water flows out through the inlet of resin tank 400 and is discharged from wastewater discharge path 2107. In some embodiments, driven gear 1431 is provided with multiple push blocks. When valve core 140 moves to the backwash position, one of the push blocks pushes the pressure rod, so that wastewater discharge path 2107 is connected to inlet pipe 114. Raw water flowing to moving backwash hole 166 flows into bypass cavity 133 through fixed bypass hole 171 (e.g. Figure 34 (Flow direction indicated by arrow 3) and then output from outlet pipe 113 to provide water to the user. Thus, the water softener can supply water continuously during backwashing.

[0262] According to some embodiments of the present invention, the valve seat 116 is provided with a water supply chamber spaced apart from the brine suction chamber 134. The valve assembly 100 also includes a water supply pipe connected to the valve body 110, and the water supply chamber communicates with the water supply pipe. A brine suction check valve 260 is provided between the water supply pipe and the jet pipe 181, and the brine suction check valve 260 is unidirectionally open based on the pressure difference between the water supply pipe and the jet pipe 181 to control the opening and closing of the jet pipe 181 and the resin tank 400. For example, in Figure 29 In the example, when the valve core 140 is in the brine suction position, the raw water flows into the jet pipe 181 through the brine suction path, and no water flows through the water supply pipe. At this time, the pressure in the jet pipe 181 is greater than the pressure in the water supply pipe. The jet pipe 181 is connected to the resin tank 400, and the raw water can flow from the jet pipe 181 to the resin tank 400.

[0263] At the water replenishment position, the movable inlet 161 is connected to both the water replenishment chamber and the brine suction chamber 134. The pressure difference between the water replenishment pipe and the jet pipe 181 is zero. The brine suction check valve 260 blocks the connection between the jet pipe 181 and the resin tank 400, while the jet pipe 181 remains connected to the brine tank 500. The brine suction chamber 134 replenishes water to the brine tank 500 through the jet pipe 181. The movable inlet 161, the water replenishment chamber, the brine suction chamber 134, and the jet pipe 181 define the water replenishment path. It is understood that the brine tank 500 typically contains salt, and it needs to maintain a "salt-only" state to prevent the brine tank 500 from failing to provide brine during use, which could lead to resin reduction failure. At the water replenishment position, water is replenished to the brine tank 500 through the water replenishment path to dissolve the salt and replenish the brine.

[0264] In some embodiments, the water supply chamber and the backwash chamber 136 are the same chamber, and the water supply pipe and the backwash pipe 182 are the same pipe; that is, the backwash chamber 136 is the water supply chamber, and the backwash pipe 182 is the water supply pipe. For ease of understanding, the structure and operation of the valve assembly 100 in the water supply position will be described below with the example of the water supply chamber and the backwash chamber 136 being the same chamber and the water supply pipe and the backwash pipe 182 being the same pipe.

[0265] like Figures 35-38 As shown, valve cores 140 are all in the water supply position at this time, and the arrows in the figure indicate the direction of water flow. Figure 35 This is a structural schematic diagram of valve assembly 100; Figure 36 This is a schematic diagram showing the relative positions of the moving plate 160 and the fixed plate 170; Figure 37 This is a schematic diagram from another perspective showing the relative positions of the moving plate 160 and the fixed plate 170. At the water replenishment position, the moving water inlet 161 is connected to the brine suction chamber 134 through the fixed brine suction port 175, and the moving water inlet 161 is connected to the backwash chamber 136 through the fixed backwash port 177. The moving backwash port 166 is connected to the tank inlet chamber 131 through the fixed tank inlet port 174. The first water inlet chamber 130, the moving water inlet 161, the water replenishment chamber, the brine suction chamber 134, and the jet pipe 181 define the water replenishment path. The first water inlet chamber 130, the moving backwash port 166, and the tank inlet chamber 131 together define the service water path.

[0266] Raw water is transported to the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112. The raw water in the first inlet chamber 130 flows through the connecting port 164 and the inlet channel 163 to the moving inlet port 161 and the moving backwash port 166. A portion of the raw water in the moving inlet port 161 flows into the backwash chamber 136 through the fixed backwash port 177, and then into the backwash pipe 182; another portion of the raw water in the moving inlet port 161 flows into the brine suction chamber 134 through the fixed brine suction port 175, and then into the jet pipe 181. In this way, the pressure of the water in the backwash pipe 182 on the brine suction check valve 260 is balanced with the pressure of the water in the jet pipe 181 on the brine suction check valve 260. The brine suction check valve 260 blocks the connection between the jet pipe 181 and the resin tank 400, while the jet pipe 181 remains connected to the brine tank 500. Thus, the water in the brine chamber 134 is transported to the brine tank 500 through the jet pipe 181 to replenish the brine. The raw water in the dynamic backwash hole 166 flows into the tank chamber 131 through the fixed inlet hole 174, and is then transported to the user end through the outlet pipe 113.

[0267] According to some embodiments of the present invention, a mixing zone is provided between the service position and the brine suction position. When the valve core 140 rotates to the mixing zone, the valve core 140 and the valve seat 116 together define the service water path and the bypass water path. Figure 6As shown, the inlet chamber 131, the brine suction chamber 134, and the bypass chamber 133 are arranged sequentially in the circumferential direction of the valve seat 116, with the service position and the brine suction position adjacent to each other. Figure 20 and Figure 27 As shown, the valve core 140 can be switched to the brine suction position by rotating a certain angle counterclockwise from the service position. Figure 40 As shown, within the mixing zone, the moving inlet 161 is connected to the inlet chamber 131, and the moving inlet 161 is connected to the moving brine suction and distribution port 165 via the brine suction connecting chamber 135. The moving brine suction and distribution port 165 is connected to the bypass chamber 133. The moving inlet 161 and the inlet chamber 131 together define the service water path, and the moving inlet 161, the brine suction connecting chamber 135, the moving brine suction and distribution port 165, and the bypass chamber 133 together define the bypass water path. A portion of the raw water from the input valve assembly 100 is transported to the resin tank 400 through the service water path to displace calcium and magnesium ions in the raw water, producing soft water. The soft water is transported to the outlet pipe 113 through the outlet pipe 115; the other portion of the raw water is transported to the outlet pipe 113 through the bypass water path. Thus, within the mixing zone, the water output from the outlet pipe 113 is a mixture of soft water and raw water. Within the mixing zone, the opening of the service water circuit and the bypass water circuit is adjusted by regulating the valve core 140, thereby adjusting the amount of soft water and raw water in the outlet pipe 113 to achieve the purpose of adjusting the water hardness.

[0268] like Figures 39 to 42 As shown, valve cores 140 are all located within the mixing zone. Among them, Figure 39 This is a structural schematic diagram of valve assembly 100, where the arrows indicate the direction of water flow. Figure 40 This is a schematic diagram showing the relative positions of the moving plate 160 and the fixed plate 170. The arrows in the diagram indicate the direction of water flow. Figure 41 Another perspective diagram showing the relative positions of the moving plate 160 and the fixed plate 170; Figure 42 This is a cross-sectional view of a water softener.

[0269] In the mixing zone, the moving inlet 161 is connected to the inlet chamber 131 via the fixed inlet 174, and is also connected to the brine suction chamber 135 via the fixed brine suction connecting hole 176. The brine suction chamber 135 is connected to the moving brine suction water distribution hole 165, which is connected to the bypass chamber 133 via the fixed bypass hole 171. The moving bypass hole 162 is connected to the second inlet chamber 132 via the fixed inlet 173. At this time, raw water is input into the first inlet chamber 130 and the second inlet chamber 132 through the inlet pipe 112. The raw water in the first inlet chamber 130 flows to the moving inlet 161 through the connecting port 164 and the inlet channel 163, and the raw water in the second inlet chamber 132 flows to the moving inlet 161 through the fixed inlet 173, the moving bypass 162, and the inlet channel 163.

[0270] A portion of the raw water in the inlet hole flows into the inlet chamber 131 through the fixed inlet tank hole 174 (e.g.) Figure 40 and Figure 41 (Flow direction indicated by arrow 1) The raw water in the inlet chamber 131 is transported to the inlet of the resin tank 400 through the inlet pipe 114 (as shown by arrow 1). Figure 42 (As indicated by the middle arrow 1), raw water enters the resin tank 400 and comes into contact with the resin to displace calcium and magnesium ions, forming soft water. The soft water is output through the central pipe 410 and the outlet of the resin tank 400, and is then transported to the outlet pipe 113 via the outlet pipe 115 (e.g., ...). Figure 42 (Flow direction indicated by middle arrow 1').

[0271] Another portion of the raw water in the inlet flows into the moving brine distribution hole 165 through the fixed brine connection hole 176 and the brine connection chamber 135, and then flows into the bypass chamber 133 (e.g., Figure 40 and Figure 41 (Flow direction indicated by arrow 2). The raw water in the bypass cavity 133 flows into the outlet pipe 113 (e.g., Figure 42 (As indicated by arrow 2 in the middle), the water in the outlet pipe 113 is a mixture of soft water and raw water. Figure 41 As shown. The adjustment can be made by adjusting the rotation angle of the valve core 140.

[0272] like Figure 9 As shown, the angle between the fixed brine suction hole 175 and the fixed bypass cavity 133 is the mixing angle. Figure 9 In the example, the mixing angle is 35 degrees; of course, the mixing angle can also be other angles. For example... Figure 20 As shown, during the process of the valve core 140 rotating from the service position to the brine suction position in the direction of the arrow, when the rotation angle is less than the mixing angle, the dynamic brine suction water distribution hole 165 is connected to the bypass cavity 133, and the dynamic brine suction water distribution hole 165 is not connected to the brine suction cavity 134.

[0273] like Figures 13-15As shown, according to some embodiments of the present invention, the adapter assembly 200 further includes an adapter integration base 210. The adapter integration base 210 has a first flow path 2101, a second flow path 2102, a mixed salt flow path 2103, a backwash flow path 2104, and an adapter cavity 2105 internally configured. Each flow path has an adapter interface on its outer periphery. One end of the first flow path 2101 is connected to the inlet pipe 114 via a corresponding adapter interface, and the other end of the first flow path 2101 is connected to the corresponding inlet pipe 114 via a corresponding adapter interface. The adapter is connected to the resin filling part 420 of the resin tank 400; one end of the second flow path 2102 is connected to the outlet pipe 115 through the corresponding adapter, one end of the mixed salt flow path 2103 is connected to the jet pipe 181, one end of the backwash flow path 2104 is connected to the backwash pipe 182, and the other ends of the second flow path 2102, the mixed salt flow path 2103 and the backwash flow path 2104 are all connected to the central pipe 410 of the resin tank 400 through the adapter cavity 2105. The second flow path 2102, the mixed salt flow path 2103, and the backwash flow path 2104 are all connected to the transfer chamber 2105. The bottom of the transfer chamber 2105 has a connection port, which is used to connect to the central tube 410 of the resin tube, so that the water can enter the central tube 410 through the transfer chamber 2105 when the salt is absorbed (slow wash), backwash, or water is replenished, forming a reverse circulation water path in the resin tank 400.

[0274] like Figure 1 and Figure 16 As shown, in a specific configuration, the adapter component 200 and the resin tank 400 are connected via a water passage component 300, meaning that water is guided into the resin tank 400 through the water passage component 300. In this embodiment, the first flow path 2101, the second flow path 2102, the mixed salt flow path 2103, and the backwash flow path 2104 are all flow channel structures constructed within the adapter integrated base 210. Each flow path has its own port formed on the outer peripheral end face of the adapter integrated base 210, and each port has a connector, which enables communication with the valve assembly 100 and the water passage component 300. Specifically, the two ends of the first flow path 2101 are connected to the inlet pipe 114 and the water passage component 300 respectively through corresponding connectors provided on the outer side of the adapter integrated base 210, thereby allowing raw water to be introduced from the inlet pipe 112 of the valve assembly 100 into the resin tank 400 filling section.

[0275] like Figure 13 , Figure 15As shown, the transfer chamber 2105 is a chamber constructed inside the transfer integration base 210. The transfer chamber 2105 is connected to the second flow path 2102, the mixed salt flow path 2103 and the backwash flow path 2104. There is a port at the bottom of the transfer chamber 2105. This port is connected to the water path component 300 or directly connected to the central pipe 410 of the resin tank 400, so that the water path can be directly connected from the transfer chamber 2105 to the central pipe 410 in the resin tank 400 to realize the flow of the reverse circulation water path. In specific configuration, one end of the second flow path 2102, one end of the mixed salt flow path 2103, and one end of the backwash flow path 2104 are all connected to the corresponding interfaces on the valve assembly 100 through corresponding adapters, so as to realize the connection between different water paths on the valve assembly 100 and the adapter assembly 200. The other end of the second flow path 2102, the other end of the mixed salt flow path 2103, and the other end of the backwash flow path 2104 are all connected to the adapter cavity 2105. The adapter cavity 2105 can realize the connection between multiple water paths and the central pipe 410 of the resin tank 400, so that the water path can flow out from the second flow path 2102 when in service position, and finally achieve soft water supply through the outlet pipe 113.

[0276] One end of the mixed salt flow path 2103 is connected to the valve chamber 111 of the valve assembly 100 through the jet pipe 181. The moving plate 160 and the fixed plate 170 in the valve chamber 111 can switch the water path, so that the raw water can enter the mixed salt flow path 2103 and mix with the brine in the mixed salt flow path 2103 and enter the central pipe 410 of the resin tank 400. The brine entering the central pipe 410 can clean the resin particles and regenerate the resin particles.

[0277] One end of the backwash flow path 2104 is connected to the valve chamber 111 of the valve assembly 100 through the backwash pipe 182. The moving plate 160 and the fixed plate 170 in the valve chamber 111 can switch the water path, so that the raw water can enter the backwash flow path 2104. The backwash flow path 2104 is connected to the central pipe 410 of the resin tank 400 through the transition chamber 2105, so that the raw water can enter through the central pipe 410 to backwash the resin particles and regenerate the resin particles.

[0278] Understandably, the construction of the adapter cavity 2105 enables multiple flow paths to be connected to the central tube 410 of the resin tank 400 through one port of the adapter cavity 2105, reducing the number of ports connecting each flow path to the central tube 410 of the resin tank 400, realizing the integration of multiple water paths, and reducing the overall space occupied by the water softener.

[0279] In specific settings, such as Figure 13As shown, one end of the first flow path 2101, the second flow path 2102, the mixed salt flow path 2103, and the backwash flow path 2104 extends in the same direction. The first flow path 2101 and the second flow path 2102 are arranged side-by-side, as are the mixed salt flow path 2103 and the backwash flow path 2104. It can be understood that the fact that one end of the first flow path 2101, the second flow path 2102, the mixed salt flow path 2103, and the backwash flow path 2104 extends in the same direction allows the valve assembly 100 and the adapter assembly 200 to achieve alignment and connection of multiple flow paths with a single alignment, simplifying the connection of the flow paths with the valve assembly 100 and facilitating disassembly and assembly. Simultaneously, the first flow path 2101 and the second flow path 2102 are arranged side-by-side, as are the mixed salt flow path 2103 and the backwash flow path 2104. By grouping and arranging flow paths with roughly the same flow rate side by side, the symmetry of the flow paths in the adapter component 200 is improved, thereby enhancing the operational stability of the adapter component 200.

[0280] like Figure 13 and Figure 29 As shown, according to some embodiments of the present invention, the adapter integration base 210 further includes a salt absorption flow path 2106. One end of the salt absorption flow path 2106 is connected to the salt tank 500, and the other end of the salt absorption flow path 2106 is connected to the mixed salt flow path 2103. The salt absorption flow path 2106 and the mixed salt flow path 2103 are connected at the front end of the adapter cavity 2105. It can be understood that the salt absorption flow path 2106 provides a certain concentration of brine to the mixed salt flow path 2103, and then mixes with the raw water in the mixed salt flow path 2103 to provide the required brine concentration for resin regeneration. When brine is needed for resin regeneration, the salt absorption flow path 2106 can effectively introduce the brine into the mixed salt flow path 2103, ensuring sufficient mixing and uniform distribution of the brine. By connecting the salt absorption flow path 2106 to the mixed salt flow path 2103, the brine supply path is simplified, improving operational convenience and device efficiency.

[0281] like Figure 14 As shown, according to some embodiments of the present invention, the adapter assembly 200 further includes an ejector 240, which is disposed at the junction of the brine suction path 2106 and the brine mixing path 2103, so that the ejector 240 can draw brine into the brine mixing path 2103. It is understood that by disposing of the ejector 240 in the brine flow path and the brine mixing path 2103, brine suction power is provided to the brine suction path 2106 when raw water passes through the brine mixing path 2103, thereby reducing the brine suction power required separately for the brine suction path 2106 and simplifying the overall structure of the water softener. Furthermore, the ejector 240 can mix the brine and raw water in the brine suction path 2106 and the brine mixing path 2103, improving the uniformity and efficiency of brine mixing, thereby ensuring sufficient resin regeneration and improving the overall treatment effect.

[0282] According to some embodiments of the present invention, the wastewater discharge path 2107 is disposed within the adapter integrated base 210, and the wastewater discharge path 2107 is connected to the resin filling part 420 of the resin tank 400 through the first flow path 2101. It is understood that the wastewater discharge path 2107 is connected to the first flow path 2101 to the resin filling part 420 of the resin tank 400. Since the resin particles are treated in a backwashing mode, that is, by using a reverse circulation water path, when the resin is cleaned and replaced, the wastewater after the resin cleaning or resin particle replacement will be discharged from the end of the resin tank 400 where the raw water enters the resin during normal soft water operation. By connecting the wastewater discharge path 2107 to the first flow path 310, the need for a separate wastewater outlet in the resin tank 400 can be reduced, simplifying the overall structure and flow path of the soft water device, and facilitating the assembly between the valve assembly 100 and the resin tank 400 or the water path component 300.

[0283] In specific settings, such as Figure 3 and Figure 14 As shown, the sewage control assembly 250 includes a sewage pressure rod 251. The sewage pressure rod 251 has an axially arranged pressing end 2511 and a mating sealing end 2512. The pressing end 2511 is located inside the driven gear 1431 and can be pressed in conjunction with the drive block 1433. The mating sealing end 2512 is located inside the sewage passage 2107. The pressing end 2511 is adapted to cause the mating sealing end 2512 to open the sewage passage 2107 after being pressed. Under normal conditions, the sewage discharge path 2107 is closed. It is only opened when sewage discharge is required. In this embodiment, under normal conditions, the drive block 1433 does not contact the pressing end 2511. When sewage discharge is required, the driven gear 1431 rotates, causing the drive block 1433 to abut against the pressing end 2511 of the sewage discharge pressure rod 251. During abutment, it can generate a thrust on its own central rod, causing the central rod to move. After the central rod moves, the sealing end 2512 can disengage from the sewage discharge path 2107, thus opening the sewage discharge path 2107. The entire process is mechanically controlled and is not affected by electromagnetic interference or other factors, thus improving the reliability of the device.

[0284] It is understood that the drain pressure lever 251 is installed in the sewage discharge passage 2107. Under normal conditions, the drain pressure lever 251 can close the sewage discharge passage. When the sewage discharge passage 2107 needs to be opened, it will be opened by the drive block 1433. In this embodiment, the drain pressure lever 251 can be a conventional drain pressure lever 251. A conventional drain pressure lever 251 includes a rod body, one end of which has a sealing head, namely the aforementioned mating sealing end 2512. When it is not necessary to open, the sealing head can block the sewage discharge passage 2107. When it is necessary to open, the sewage discharge passage 2107 is opened by external force. For the specific drain pressure lever 251, those skilled in the art should know its specific structure, so it will not be described in detail here.

[0285] For example, in a practical application, the position with the drive block 1433 on the driven gear 1431 is configured as the salt suction position, and controlled by a control system. That is, when the control system sends a signal that salt suction is needed, the driven gear 1431 rotates, and the drive block 1433 abuts against the squeezing end 2511 of the sewage discharge lever 251, thereby opening the sewage discharge passage 2107. When the sewage discharge passage 2107 is not needed, the driven gear 1431 is rotated to displace the drive block 1433 from the squeezing end 2511 of the sewage discharge lever 251, so that the sewage discharge lever 251 can close the sewage discharge passage 2107 again.

[0286] It is understood that in this embodiment, the opening of the sewage discharge passage 2107 is achieved by setting a drive block 1433 on the driven gear 1431. The overall structure is simple and efficient, and can quickly respond to achieve the rapid opening of the sewage discharge passage 2107. Moreover, the opening of the sewage discharge passage 2107 is achieved through mechanical transmission, which has higher reliability and anti-interference ability.

[0287] like Figure 3 As shown, in a specific configuration, there can be multiple drive blocks 1433, which are arranged at intervals. In the overall product, sewage discharge is often required in multiple states. In this embodiment, by setting multiple drive blocks 1433 on the driven gear 1431, sewage discharge can be achieved in different states, thus improving the applicability of the sewage discharge system in this example.

[0288] like Figure 3As shown, two drive blocks 1433 are provided on the driven gear 1431. The two drive blocks 1433 are located at different positions. Through the different distribution of positions, the two drive blocks 1433 can be controlled to open the sewage discharge channel in at least two states. Of course, there can also be three or four drive blocks 1433, etc., and the different distribution of the drive blocks 1433 is usually used to achieve the correspondence between the drive blocks 1433 and different states. The accompanying drawings of this application only illustrate the use of two drive blocks 1433.

[0289] In practical applications, the two drive blocks 1433 have the same structure and the same material. Of course, the two drive blocks 1433 can also have different structures. In some examples, the minimum distance between multiple drive blocks 1433 and the pressing end 2511 of the drain lever 251 is approximately the same. Theoretically, the minimum distance between multiple drive blocks 1433 and the lever assembly should be equal, but due to processing and assembly, there is often a certain error. Therefore, it is sufficient for the minimum distance to be approximately the same. It can be understood that this minimum distance reflects the depth of the drain lever 251's movement. Generally speaking, the drain lever 251 has a fixed depth of movement to achieve a complete seal on the drain passage 2107. By limiting the minimum distance to be equal, the drain passage 2107 can be opened stably and ensured to be fully open, thereby improving its opening stability.

[0290] According to one embodiment provided by the present invention, such as Figure 3 As shown, a lever mechanism 270 is provided between the drive block 1433 and the drain pressure rod 251. The lever mechanism 270 is used to amplify and transmit the thrust. The drive block 1433 is mounted on the driven gear 1431, which is connected to the rotating shaft 150 to transmit mechanical energy, causing the moving plate 160 to rotate and switch the water path. In this embodiment, the lever mechanism 270 improves the service life of the drain pressure rod 251 and reduces the difficulty and cost of maintenance.

[0291] It is understandable that the driven gear 1431 meshes with the drive gear 1432 and is connected to the rotating shaft 150. The direct interaction between the drive block 1433 and the drain pressure rod 251 makes the drive block 1433 susceptible to damage, especially over extended periods. Damage to the drive block 1433 necessitates the disassembly of the driven gear 1431, which is difficult and can damage the valve core 140 during disassembly. In this embodiment, a lever mechanism 270 is provided between the drive block 1433 and the drain pressure rod 251. This lever mechanism facilitates transmission, significantly reducing the risk of damage to the drive block 1433 and extending its service life. Furthermore, compared to the disassembly and maintenance of the driven gear 1431, the lever mechanism 270 is easier to disassemble and maintain, with lower difficulty and cost.

[0292] like Figure 14 and Figure 29 As shown, according to an embodiment of the present invention, the transfer assembly 200 further includes a brine backflow preventer 260, which is disposed within the transfer chamber 2105 and located at the end of the brine mixing flow path 2103. It is understood that the brine backflow preventer 260 can be a one-way valve, a check valve, or a similar component, and its working principle prevents backflow to improve the reliability and stability of the water softener, reducing the possibility of maintenance and malfunctions. Simultaneously, the application of the brine backflow preventer 260 ensures the accuracy and continuity of brine supply, meeting the needs of resin regeneration and improving the overall treatment effect.

[0293] In the specific configuration, a first adapter 220 and a second adapter 230 are provided on the bottom end of the adapter integration base 210. The first adapter 220 is connected to the first flow path 2101, enabling the first flow path 2101 to connect with the resin filling part 420 in the resin tank 400. The second adapter 230 is connected to the adapter cavity 2105, enabling each flow path to connect with the central tube 410 in the resin tank 400. It can be understood that through the cooperative use of the first adapter 220 and the second adapter 230, the connection between the adapter cavity 2105 and the central tube 410, and between the first flow channel 310 and the resin tank 400 can be easily realized, improving the flexibility and maintainability of the device.

[0294] like Figures 16-18As shown, according to an embodiment of the present invention, the water channel component 300 includes a main body 301, which is connected to a resin tank 400. The main body 301 includes a first flow channel 310 and a second flow channel 320. The resin tank 400 is located below the first flow channel 310 and the second flow channel 320. The first flow channel 310 has a first connection end 330 for fluid input or fluid output, and the second flow channel 320 has a second connection end 340 for fluid input or fluid output. The first flow path 2101 is connected to the resin filling part 420 in the resin tank 400 through the first connection end 330, and the transition cavity 2105 is connected to the central tube 410 in the resin tank 400 through the two connection ends. The first flow channel 310 has a first connection port 350 for communicating with the resin filling part 420 of the resin tank 400; the first connection end 330 is fixedly connected to the first flow channel 310 and the two are interconnected, wherein the first connection end 330 is used for fluid input or fluid output; the second flow channel 320 has a second connection port 360 for communicating with the central tube 410 of the resin tank 400; the second connection end 340 is fixedly connected to the second flow channel 320 and the two are interconnected, wherein the second connection end 340 is used for fluid input or fluid output. In the design of water circuit components, it is necessary to meet the switching of five functional channels in the water softener: water supply, backwashing, regeneration, water replenishment, and forward washing. Therefore, water circuit components usually integrate multiple flow channels into a single structure. This undoubtedly requires complex molding molds to construct multiple flow channels. In this embodiment, two flow channels, namely the first flow channel 310 and the second flow channel 320, are used. The two flow channel pipes are respectively provided with connecting ports 164, namely the first connection port 350 and the second connection port 360. Figure 18 As shown. The two connection ports enable two flow channels to be connected to the resin filling section 420 and the central tube 410 in the resin tank 400, respectively. The central tube 410 and the resin filling section 420 surrounding the central tube 410 are isolated by their own tube walls. This allows the two connection ports to be connected to different parts of the resin tank 400, thereby enabling the switching of the flow direction within the resin tank 400.

[0295] In this embodiment, the first flow channel 310 and the second flow channel 320 are used for the input or output of liquid fluid, respectively. The determination of the input or output is controlled and selected by the valve assembly 100 connected to them. It is understood that the valve assembly 100 needs to meet the softening water path in the water softening process, and also needs to meet the regeneration path for the treatment of resin particles in the resin tank. For example, during softening, raw water enters the first flow channel 310 through the first connection port 350, and is softened by the resin particles in the resin tank 400. The treated water rises through the central pipe 410 and is output through the second flow channel 320 and the second connection port 360. At this time, the first connection port 350 is used for fluid input, and the second connection port 360 is used for fluid output. During regeneration, brine enters the second flow channel 320 through the second connection port 360 and enters the bottom of the resin tank 400 through the central tube 410. The brine entering the bottom can rise along the outer periphery of the resin tank 400 to clean the resin particles. Then it enters the first flow channel 310 and is output from the first connection port 350 in the first flow channel 310. At this time, the first connection port 350 is used for fluid output and the second connection port 360 is used for fluid input.

[0296] It is understandable that in this embodiment, the switching between the soft water path and the regenerated water path is realized through two flow channels, which simplifies the construction of the number of flow channels, makes the overall structure simple, and reduces the difficulty of preparation.

[0297] like Figure 16 As shown, in the specific setup, both the water channel component 300 and the resin tank 400 are made of plastic. Plastic is easy to mold and facilitates the construction of flow channels and complex shapes. Moreover, the one-piece molding of plastic can combine multiple plastic materials together to form a compact and seamless product.

[0298] In specific applications, such as Figure 18 As shown, the first connection port 350 is a cut-off port, and the cross-sectional area of ​​the first connection port 350 in the cross-sectional direction of the resin tank 400 is less than or equal to the overlapping surface of the first flow channel 310 and the resin filling part 420 in the cross-section. The water channel, through its connection with the resin tank 400, enables the basic functions of a water softener. That is, raw water can enter the resin tank 400 through the first flow channel 310 and flow forward to achieve softening, while brine can return from the first flow channel 310 to the mixing channel and enter the central pipe 410 to achieve reverse flow. In this embodiment, the first connection port 350 is opened along the extension direction of the first flow channel 310, as long as the cut-off port does not exceed the corresponding range of the resin tank 400. This allows the size of the first connection port 350 to be unrestricted, ensuring that the water distribution effect is not affected by the opening size when raw water is distributed through the first connection port 350.

[0299] That's understandable. For example... Figure 18 As shown, in this embodiment, a portion of the first flow channel 310 extends across the resin tank 400, resulting in an intersecting plane between the first flow channel 310 and the resin tank 400 in the horizontal direction. This intersecting plane is the aforementioned cross-section. In other words, a portion of the first flow channel 310 is located within the resin tank 400. The outer portion of the resin tank 400 is a resin filling portion 420 filled with resin particles. The first connection port 350 can have an opening of any size on the portion of the first flow channel 310 located within the resin tank 400, allowing it to be open regardless of the inner diameter of the first flow channel 310. This enables a larger first connection port 350 to be opened along the extension direction even on a first flow channel 310 with a smaller inner diameter, thereby achieving a high-quality water distribution effect.

[0300] Specifically, in this embodiment, since a portion of the wall forming the first flow channel 310 spans above the resin tank 400, and a first connection port 350 is opened on the wall above the resin tank 400, the portion of the wall facing the resin tank 400 can all be a notch structure. At this time, the size of the first connection port 350 is equal to the overlapping portion of the wall and the resin filling part 420 inside the resin tank 400. This increases the contact area between the first connection port 350 and the resin filling part 420 of the resin tank 400, thereby improving the water distribution effect of the raw water entering the resin tank 400 through the first connection port 350, enabling the water to fully contact the resin, thereby improving the softening efficiency and softening quality of the water.

[0301] According to one embodiment of the present invention, a plurality of resin tanks 400 are connected to the main body 301. The plurality of resin tanks 400 are arranged side by side at intervals along the extension direction of the first flow channel 310 or the extension direction of the second flow channel 320. The first connecting end 330 and the second connecting end 340 are both located on the same part of the plurality of resin tanks 400. The resin tanks 400 are used to fill resin, and the amount of resin filled directly affects the water treatment effect. In related technologies, due to factors such as assembly method, a single resin tank 400 is usually used. However, if a single resin tank 400 is to fill more resin particles, it needs to have a larger volume, which makes the entire component occupy a large space in the width direction, thus making the overall structure complex and not conducive to installation. In this embodiment, the arrangement of multiple resin tanks 400 can make them narrower in the width direction while having the same volume, which is conducive to the assembly of the component.

[0302] In specific settings, such as Figure 1 Figure 18As shown, in this embodiment, there are two resin tanks 400, arranged side by side. When determining the number of resin tanks 400, the water treatment capacity requirements of the entire water circuit board and the overall structural space requirements are usually considered. Therefore, in some specific designs, three, four, or more resin tanks 400 can be selected. It is understood that with the addition of resin tanks 400, the flow channels will be arranged accordingly along the length direction to achieve communication between the resin tanks 400 and the flow channels, forming a water circuit. The accompanying drawings of this application's embodiments are only an example illustrating two resin tanks 400.

[0303] like Figure 17 As shown, the first flow channel 310 and the second flow channel 320 both extend in a straight horizontal direction. Correspondingly, the resin tank 400 is arranged side by side in a straight horizontal direction. The fluid in the first flow channel 310 and the second flow channel 320 can enter the resin tank 400 for processing, and then output or input is realized through the first connection end 330 and the second connection end 340 to realize the positive circulation water flow or the reverse circulation water flow.

[0304] In specific settings, such as Figure 1 As shown, both the first connecting end 330 and the second connecting end 340 are provided with quick-connect holes, and quick-connect plugs are provided in the quick-connect holes. Both the first connecting end 330 and the second connecting end 340 are connected to the adapter assembly 200 through the quick-connect plugs. Typically, water softeners are installed in a relatively confined space, which makes assembly and disassembly somewhat difficult. In this embodiment, a quick-connect connection is used to facilitate assembly and disassembly.

[0305] In specific configurations, various quick-connect fittings are available, such as quick couplings, quick rotary couplings, quick clamp couplings, and compression couplings commonly used in pipe connections. In this embodiment, a socket is provided on the first connecting end 330, a connector is provided on the adapter assembly 200, and an annular groove is formed on the connector. The connector is inserted into the first connecting end 330, and then a snap-fit ​​piece is inserted into the socket. A portion of the snap-fit ​​piece is located within the annular groove, thereby achieving a quick-connect connection between the adapter assembly 200 and the connecting port. In the working state, the snap-fit ​​piece is located within the groove to achieve snap-fit. When disassembly is required, the snap-fit ​​piece can be removed to complete the disassembly, simplifying the entire assembly and disassembly process.

[0306] like Figure 16 and Figure 18As shown, according to an embodiment of the present invention, the resin tank 400 and the water channel component 300 are integrally formed. The resin tank 400 includes a tank body and a lid. The tank body has a receiving cavity and an installation opening communicating with the receiving cavity. The lid is placed on the installation opening to connect the lid and the tank body. After the tank body of the resin tank 400 and the water channel component 300 are integrally formed, the upper part of the tank body and the water channel component 300 are in an integral structural state. In order to facilitate the installation of the water distributor and the filling of resin particles, a lid structure is provided, which can achieve the sealing of the resin tank 400.

[0307] The can body is roughly hollow and cylindrical, with an internal cavity forming a storage chamber. This storage chamber is the main part of the resin can 400 assembly and is used to store the resin. The design of the storage chamber can vary in shape and size to accommodate different resin volumes and performance requirements, and no specific limitations are imposed here.

[0308] It is understood that the resin tank 400 assembly may include one or more tank bodies arranged in parallel, with the mounting openings of the tank bodies aligned to the same side for ease of installation. In specific applications, a tank opening is provided on one end face of the tank body, and the opening end is integrally formed with the water channel component 300. The opening is used to allow and control the flow of fluid into and out of the receiving cavity. The size and shape of the opening can be adjusted according to actual needs to optimize the flow performance of the resin. Simultaneously, the water channel plate or pump body is provided with a connecting port 164 communicating with the tank opening, thereby realizing water channel communication between the tank body and the water channel plate or pump body. An installation opening is provided at the end of the tank body away from the water channel component 300. This installation opening facilitates the setting of the molding process of the tank body and the assembly and installation of other components of the tank body, such as water distributors. Bolt holes are provided on the outer periphery of the end of the tank body with the installation opening.

[0309] like Figure 18 As shown, the cover is placed over the installation opening to seal it and ensure a relative seal of the receiving cavity. The cover and the tank body are axially connected and fixed using screws and other connectors. It is understandable that during use, the resin tank 400 assembly requires a certain pressure to push the internal softening flow path. Therefore, when the tank opening or receiving cavity is axially positioned, the resin tank 400 assembly will exert a spreading force between the cover and the tank body during operation. Under unstable water pressure, coupled with the repeated action of this spreading force, the bolt connection ensures a stable connection between the cover and the tank body.

[0310] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment drives the transmission mechanism 141 through a driving device. The transmission mechanism 141 can control the valve core 140 to switch the water circuit on the one hand, and on the other hand, through the cooperation of the transmission mechanism 141 and the adapter component 200, it can control the opening of the sewage discharge circuit 2107 in the adapter component 200, thereby realizing the control of the entire water circuit, simplifying the control logic, improving the control efficiency, reducing the number of components, and reducing the failure rate of the water circuit control component. Furthermore, the sewage discharge control component 250 is a sewage discharge pressure rod 251. The sewage discharge pressure rod 251 opens the sewage discharge circuit 2107 by pressing against the drive block 1433 on the driven gear 1431. This is achieved through mechanical transmission. The entire switch has a simple structure and strong reliability and stability.

[0311] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the protection scope of the invention.
