[0094] Hard water can have a variety of impacts on daily life and household appliances. For example, it can reduce washing efficiency, accumulate in pipes, reducing water flow, impairing equipment performance and lifespan, and causing skin problems. Therefore, people often use water softeners to treat their tap water. Using water softeners can effectively remove minerals from hard water, improving water quality and enhancing the quality of life. Water softeners typically work by removing calcium and magnesium ions from water through an ion exchange process, thereby converting hard water into soft water.

[0095] Resin treatment is a common method. Resin is a polymer with a unique structure that carries a positive surface charge. When hard water passes through the resin particles, the calcium and magnesium ions in the resin attract the positive charges on the resin surface, replacing the sodium ions already on the resin. Over time, the resin particles gradually become saturated, requiring cleaning by aspirating salt water to regenerate the resin particles by replacing the adsorbed ions.

[0096] In the related art, household water softening equipment is limited by the size of the resin tank, which is usually large in size. The general resin tanks on the market are made of fiberglass wrapped with plastic. Due to the winding molding process, the upper and lower ends need to be designed with a tapered design to ensure strength requirements. At the same time, for strength reasons, a circular cross-section is uniformly adopted. Usually, household water softeners adopt a single resin tank design, which has a circular cross-section, and the chassis usually adopts a square design. Therefore, there is usually a large amount of wasted space in the four corners of the chassis, which makes the lateral size of the water softener seriously limited by the size of the tank.

[0097] The embodiments of the present invention refer to Figure 1-Figure 45 As shown, a water softener is provided.

[0098] According to an embodiment of the present invention, please refer to Figure 16 、 Figure 18 、 Figure 43 and Figure 44 A water softener according to an embodiment of the present invention includes a housing 10, a plurality of resin tanks 400, and a water channel member 300. The housing 10 is formed with 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 channel member 300 is arranged in the accommodating space. A plurality of mounting ports 302 are provided on one side of the water channel member 300. The mounting ports 302 are connected to the resin tanks 400 in a one-to-one correspondence.

[0099] In this embodiment, the housing 10 is a rectangular parallelepiped and includes a front panel 11, a rear cover 12, an upper top panel 16, a lower bottom panel, and left and right side panels 21. These panels enclose a space for accommodating a resin tank 400 and a water channel member 300. The resin tank 400 can be filled with ion exchange resin to remove hard ions such as calcium and magnesium from the water, thereby softening the water. The water channel member 300 is connected to the resin tank 400 to provide water inlet and outlet to the resin tank 400.

[0100] It can be understood that in this embodiment, by arranging multiple resin tanks 400 side by side along the length direction of the shell 10, the size of the resin tank 400 in the width direction is reduced when the same volume of resin is filled, and the overall arrangement is rectangular, which facilitates the design of the entire machine into a thinner rectangular shape, improves the space utilization of the water softening device, realizes the miniaturized design of the water softening device, and facilitates the installation of the water softening device in narrow spaces with size restrictions such as cabinets, balconies, and bathroom cabinets, thereby improving the applicability of the water softener.

[0101] According to one embodiment of the present invention, referring to Figure 44 and Figure 45 The water softener further includes a salt tank 500 , which is disposed in the accommodating space and connected to the resin tank 400 to supply salt solution to the resin tank 400 during backwashing. The salt tank 500 is disposed side by side with the resin tank 400 along the length direction of the housing 10 .

[0102] It is understandable that salt can be stored in the salt tank 500 of the water softener. When the water softener is in use, after the resin tank 400 has adsorbed enough hardness ions, a backwash operation is required for cleaning. At this time, the salt stored in the salt tank 500 will be dissolved into brine and flow into the resin tank 400 through the backwash valve to regenerate the resin tank 400.

[0103] In an alternative embodiment, reference Figure 43-45 As shown, the water softener includes two resin tanks 400 arranged side by side, each of which has a filtration space for filtering water. A salt tank 500 is formed with a salt storage space inside. The salt storage space is connected to 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.

[0104] In this embodiment, on the one hand, two parallel resin tanks 400 are arranged inside the shell 10, so that the two side-by-side resin tanks 400 can work at the same time, which can improve the efficiency of water treatment to a certain extent. In some cases, when one resin tank 400 is undergoing the regeneration process, the other resin tank 400 can continue to provide softened water, thereby achieving continuous water supply and reducing downtime. In addition, the side-by-side arrangement allows the two resin tanks 400 to work independently, that is, if one resin tank 400 needs maintenance or replacement, the other resin tank 400 can still continue to work, ensuring the continuity of water supply and the reliability of the system. Most importantly, the side-by-side arrangement can make more efficient use of space, especially in an environment with limited space. The above layout makes the overall size of the water softener more compact and thinner, making it easy to install and integrate into existing water treatment systems, and can also be used in narrow gap spaces.

[0105] In this embodiment, the salt tank 500 and the resin tank 400 are placed inside the shell 10 of the water softener and arranged along the length direction of the shell 10. This can fully utilize the storage space of the water softener, avoid occupying too much space in the width direction, improve space utilization, and thus improve the applicability of the water softener. The salt tank 500 can be connected to the water softener through reasonable pipes to achieve brine supply, ensuring the normal operation of the water softener.

[0106] According to one embodiment of the present invention, referring to Figure 43-45 As shown, the shell 10 includes a front panel 11 and a rear cover 12. A salt injection window 102 is provided on the front panel 11. The salt box 500 is arranged on the side of the resin tank 400 facing the front panel 11. The salt box 500 includes a box body 510 and a box cover 520. The box body 510 and the resin tank 400 are arranged side by side. The box body 510 forms a accommodating cavity connected to the salt injection window 102. The box cover 520 can be rotatably arranged on the box body 510 to open or close the salt injection window 102.

[0107] It will be appreciated that in this embodiment, the front panel 11 is the side of the water softener that faces the user during use, and the rear cover 12 is opposite the front panel 11 and is the side of the water softener that faces away from the user during use. By providing a salt injection window 102 on the front panel 11, the lid 520 can be rotated to open or close the salt injection window 102, thereby reducing the height footprint of the water softener and its overall size. By configuring the lid 520 to be rotatable to open or close the salt injection window 102, when the lid 520 is in the closed position, the salt injection window 102 is effectively shielded, preventing the salt particles within the salt tank 500 from becoming damp, contaminated, or spilling. When the lid 520 is in the open position, the side of the lid 520 facing the salt injection window 102 can guide salt particles into the salt tank 500 body, thereby buffering the salt particles and preventing them from directly falling into the salt tank 500 body and impacting the inner wall of the salt tank 500 body. Furthermore, the salt particles can be evenly distributed in the salt tank 500 by guiding the salt particles, thereby improving the uniformity of the salt water in the salt tank 500. Furthermore, the lid 520 can be rotated to open and close, and when closed, the space occupied by the water softener can be reduced.

[0108] According to one embodiment of the present invention, referring to Figure 44 and Figure 45 At least one side surface of the salt box 500 is provided with a second clamping structure 540 for clamping with the resin tank 400 to clamp and connect the salt box 500 and the resin tank 400.

[0109] In an optional embodiment, a second snap-fit ​​structure 540 is used to connect the salt tank 500 to the resin tank 400. This snap-fit ​​installation simplifies the installation and replacement process of the resin tank 400. This quick connection mechanism makes it easier for maintenance personnel to remove and replace the resin tank 400, reducing maintenance time and labor. Furthermore, the snap-fit ​​installation provides a secure connection, helping to ensure the stability of the resin tank 400 during operation and reducing potential problems caused by loose connections.

[0110] The second clamping structure 540 may be in the form of a hook type, a latch type, a magnetic type, a wedge lock type, a buckle type, a slot type or an elastic fastener, which is not specifically limited in this embodiment.

[0111] The number of second clamping structures 540 can be one or more. When multiple second clamping 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, a second clamping structure 540 is provided on both sides of the salt tank 500, and there are multiple second clamping structures 540. The multiple second clamping structures 540 are arranged along the height direction of the housing 10, further improving the firmness and stability of the connection between the salt tank 500 and the resin tank 400.

[0112] In addition, the snap-on design provides a secure connection between the resin tank 400 and the brine tank 500, ensuring that the two tanks will not accidentally separate during operation, thereby ensuring the stability and safety of the system. Furthermore, this snap-on design makes the water softener's components highly modular, allowing for easy addition, removal, or replacement of components as needed, enhancing the system's flexibility and scalability. Furthermore, a good snap-on design helps prevent brine or softened water from leaking at the connection, ensuring efficient operation of the system. For users, this snap-on design also simplifies the operating process, making maintenance and component replacement easy even for non-professionals, reducing the difficulty of use.

[0113] Furthermore, the above design allows the system to be expanded or reduced as needed. If processing capacity needs to be increased, additional resin tanks 400 can simply be added without requiring major modifications to the entire system. Furthermore, the side-by-side arrangement and snap-on mounting design potentially reduce manufacturing and maintenance costs. The simplified installation process reduces the time and materials required for installation and maintenance, thereby lowering overall costs.

[0114] According to one embodiment of the present invention, referring to Figure 43-45 , at least one of the height and width of the salt box 500 and the resin tank 400 is equal.

[0115] In one optional embodiment, the salt box 500 and the resin tank 400 are of equal height. In another optional embodiment, the salt box 500 and the resin tank 400 are of equal width. In another optional embodiment, the salt box 500 and the resin tank 400 are of equal height and equal width. Such a design can make the two components better cooperate with each other to form a compact structure, thereby minimizing the overall size of the water softener.

[0116] By making the height and width of the salt box 500 and the resin tank 400 equal, they can be arranged more compactly inside the water softener housing 10 during installation. This compact arrangement can fully utilize the storage space of the water softener, avoid wasting space, and improve the space utilization rate of the water softener.

[0117] According to one embodiment of the present invention, the housing 10 includes a plurality of detachably mounted shell plates 13 , which enclose an accommodating space. At least one shell plate 13 is detachably connected to at least one of the resin tank 400 and the salt box 500 .

[0118] As will be appreciated, the housing 10 includes multiple panels 13 that are detachably connected to each other. The panels 13 are further subdivided into a front panel 11, a rear cover 12, an upper top panel 16, a lower bottom panel, and side panels 21, which together enclose a housing space. The detachable connection between the panels 13 facilitates maintenance and replacement of the water softener. To maintain or replace a component, the user simply removes the corresponding panel 13. This also makes the water softener more flexible and adaptable to different installation environments and usage requirements.

[0119] In one optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400, for example, the lower base 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 housing 10 and the resin tank 400 do not accidentally separate during operation of the water softener, thereby ensuring system stability and safety. In another optional embodiment, at least one shell plate 13 is detachably connected to the salt tank 500, for example, the lower base plate and the front cover are detachably connected to the salt tank 500. This facilitates user maintenance and replacement of the salt tank 500 and ensures that the housing 10 and the salt tank 500 do not accidentally separate during operation of the water softener, thereby ensuring system stability and safety. In another optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400, and at least one shell plate 13 is detachably connected to the salt tank 500. The design can be based on actual application requirements and is not specifically limited in this embodiment.

[0120] According to one embodiment of the present invention, referring to Figure 43-45 A first clamping structure 530 is provided on the outside of at least one of the salt box 500 and the resin tank 400 , and at least one shell plate 13 is clamped and installed on the first clamping structure 530 so that the shell plate 13 fits the outside of the salt box 500 or the resin tank 400 .

[0121] It can be understood that in this embodiment, a first clamping structure 530 is provided on the salt box 500 or the resin tank 400. When assembling the water softener, the salt box 500 and the resin tank 400 can be first clamped together by the second clamping structure 540, and then the shell plate 13 can be installed on the outside of the salt box 500 or the resin tank 400. The shell plate 13 can be directly installed on the outside of the salt box 500 or the resin tank 400 through the first clamping structure 530, so that the shell plate 13 is directly attached to the outside of the salt box 500 or the resin tank 400, making the connection between the shell plate 13 and the salt box 500 or the resin tank 400 tighter, thereby increasing the stability and firmness of the water softener. In addition, since the shell plate 13 is directly attached to the outside of the salt box 500 or the resin tank 400, the volume of the water softener can be made thinner, thereby saving space and facilitating installation.

[0122] The number of first clamping structures 530 can be one or more. When multiple first clamping 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, the first clamping structures 530 are provided on both sides of the salt tank 500 or the resin tank 400, and the number of first clamping structures 530 is multiple. The multiple first clamping structures 530 are arranged along the height direction or the length direction of the shell 10, further improving the firmness and stability of the connection between the salt tank 500 and the resin tank 400.

[0123] According to one embodiment of the present invention, referring to Figure 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 matching the buckle 14 .

[0124] It can be understood that in this embodiment, the two adjacent shell plates 13 can be connected by the clips 14 and the slots 15. The design of the clips 14 and the 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.

[0125] It is understandable that there can be multiple buckles 14 and slots 15, and the buckles 14 and slots 15 are arranged in a one-to-one correspondence to ensure that the connection between the shell plates 13 is tighter and firmer, ensuring the stability and firmness of the water softener.

[0126] According to one embodiment of the present invention, referring to Figure 16 and Figure 18 The water channel member 300 is disposed above the resin tank 400 .

[0127] In the related art, the water channel member 300 has a complex structure and is arranged in the width direction of the housing 10 relative to the resin tank 400, resulting in a larger water softener. To address this issue, the present embodiment places the water channel member 300 above the resin tank 400. Alternatively, the water channel member 300 can be arranged along the length of the housing 10, that is, the water channel member 300 and the resin tank 400 are stacked one above the other in the length direction. This ensures smooth water flow within the water softener, facilitates maintenance and operation, and reduces the width of the water softener, making the structure more compact and thus reducing the size of the water softener.

[0128] According to one embodiment of the present invention, referring to Figure 16-Figure 18 A plurality of flow channels 303 arranged in parallel are defined in the water channel component 300 , and each flow channel 303 is connected to a corresponding resin tank 400 , so that the plurality of resin tanks 400 are connected in parallel.

[0129] It will be appreciated that in this embodiment, each resin tank 400 has its own independent flow channel 303. After entering the water channel member 300, water flows through different flow channels 303 into each resin tank 400. After being processed within the resin tank 400, it flows out of the water softener for use by the user. This parallel arrangement allows multiple resin tanks 400 to operate simultaneously without interfering with each other. Each resin tank 400 acts as an independent processing unit, capable of performing its own softening treatment, thereby improving the overall processing efficiency and capacity of the water softener.

[0130] By arranging multiple resin tanks 400 in parallel and defining corresponding flow channels 303, the water softener can more flexibly respond to different water treatment requirements. At the same time, maintaining the independent operation of the resin tanks 400 can also prevent the normal operation of the entire system from being affected when a resin tank 400 fails.

[0131] According to one embodiment of the present invention, referring to Figure 18 , along the height direction of the resin tank 400 , the cross-sectional area of ​​the resin tank 400 is equal.

[0132] In an optional embodiment, the cross-section of the resin tank 400 is circular, and the diameter of the cross-section of the resin tank 400 is constant along the height direction of the resin tank 400. It is understood that by arranging the resin tank 400 with equal diameters along the axis, this embodiment can increase the proportion of the resin tank 400 to the surrounding area of ​​the storage space, thereby improving the arrangement ratio of the resin tank 400 in the storage space. At the same time, under the same resin capacity, the axial height of the resin tank 400 can be reduced, which is conducive to the miniaturization of the water softener design.

[0133] According to one embodiment of the present invention, referring to Figure 16-Figure 18 The resin tank 400 can be detachably connected to the mounting port 302 ; or, the water channel component 300 and the resin tank 400 are integrally formed.

[0134] It is understood that in an optional embodiment, the resin tank 400 is provided with external threads and the mounting opening 302 is provided with internal threads, and the water channel member 300 can be securely connected to the resin tank 400 through a detachable connection between the resin tank 400 and the mounting opening 302. This connection method can provide better stability and reliability, ensuring that the water channel member 300 will not loosen or fall off during use.

[0135] In another optional embodiment, the water channel member 300 is integrally formed with the resin tank 400. It is understood that integrally forming a portion of the water channel member 300 with the resin tank 400 can reduce the number of assembly structures between the water channel member 300 and the resin tank 400, thereby reducing the space occupied by the assembly structure, further improving the utilization of the space, and facilitating a miniaturized design of the resin tank 400. Furthermore, the integral molding of the water channel member 300 and the resin tank 400 can simplify the assembly process, improve assembly efficiency, and enhance the sealing performance of the water channel member 300.

[0136] According to one embodiment of the present invention, referring to Figure 43-45 Side plates 21 are extended on both sides of the resin tank 400. The side plates 21 are suitable for connecting with the housing 10. The side plates 21 define an installation cavity, and the water channel component 300 is arranged in the installation cavity.

[0137] As will be appreciated, in this embodiment, side panels 21 extend along the height of the housing 10 on either side of the resin tank 400. The connection between the side panels 21 and the housing 10 securely holds the resin tank 400 within the water softener, ensuring its stability. Furthermore, the mounting cavity defined by the side panels 21 provides a dedicated space for the water channel components 300, allowing for their orderly arrangement and installation.

[0138] Placing the water channel member 300 within the installation cavity makes the water softener's water system more centralized and compact, facilitating maintenance and operation. The design of the installation cavity also effectively isolates the water channel member 300 from other components, preventing interference. Therefore, the placement of the side panels 21 and the confinement of the installation cavity provide improved connectivity and support, creating an organized space for the installation of the water channel member 300. This design optimizes the water softener's structural layout, enhancing its stability and ease of use.

[0139] According to one embodiment of the present invention, referring to Figure 43-45 The water softener also includes a valve assembly 100 and an adapter assembly 200. The valve assembly 100 is arranged in the accommodating space. The adapter assembly 200 connects the valve assembly 100 and the water channel component 300 to control the flow direction of the water channel in the resin tank 400, wherein the adapter assembly 200 and the water channel component 300 are detachably connected. The valve assembly 100 can control the inflow and outflow of water through a switch, thereby achieving control of the water channel in the resin tank 400. The function of the adapter assembly 200 is to connect the valve assembly 100 and the water channel component 300. It can be detachably connected to the water channel component 300 through threads, quick connectors or other connection methods. This design makes the maintenance of the water softener more convenient. When the water channel component 300 needs to be replaced or cleaned, it can be easily disassembled from the adapter assembly 200.

[0140] Through the design of the valve assembly 100 and the adapter assembly 200, the water softener can control the flow direction of the water channel in the resin tank 400 and facilitate the replacement and maintenance of the water channel component 300. This design improves the functionality and maintainability of the water softener, making it more suitable for different water treatment needs.

[0141] In the related art, a conventional water channel component 300 is integrated with various channels for communicating with the resin tank 400, and is also integrated with 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 in the width direction of the entire water channel component 300. It has a large dimensional extension, which makes the entire water channel component 300 complex in structure, difficult to manufacture, and occupies a large space. In particular, the water channel component 300 requires more space in the width direction to realize its own layout.

[0142] According to one embodiment of the present invention, referring to Figure 43-45 The water softener includes a housing 10, a resin tank 400, a water channel component 300, a valve assembly 100 and an adapter assembly 200. The housing 10 forms an accommodating space, the resin tank 400 is arranged in the accommodating space, the water channel component 300 is arranged in the accommodating space and is located above the resin tank 400, the water channel component 300 is connected to the resin tank 400, and the valve assembly 100 is connected to the water channel component 300 through the adapter assembly 200 to control the flow direction of the water in the resin tank 400.

[0143] It can be understood that in this embodiment, by independently arranging the valve assembly 100, the adapter assembly 200 and the water channel component 300, the overall structure of the water channel part is simplified, and the difficulty of preparing the water channel component 300 is reduced. The water channel component 300 is arranged above the resin tank 400, and the resin tank 400 can be stacked and arranged in the vertical direction, reducing the area occupied by the bottom of the water softener. The separate connection of each component is beneficial to the overall layout, thereby simplifying the overall structure, improving the space utilization of the water softening device, and realizing the miniaturized design of the water softening device, which is convenient for the water softening device to be installed in narrow spaces with size restrictions such as cabinets, balconies, and bathroom cabinets, thereby improving the applicability of the water softening device.

[0144] During the switching process of each water channel, 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 channel is input from the resin filling area at the top of the resin tank 400, then rises through the central tube 410 and is output. In the regeneration water channel state, the water channel is input from the central tube 410, then rises through the resin particle filling area and is output. In other words, the flow direction of the regeneration water channel and the flow direction of the soft water water channel need to be opposite. In this embodiment, the connection with the resin tank 400 is achieved through the water channel component 300, and the flow direction of the water channel is controlled by the adapter assembly 200 connected thereto, thereby realizing the formation of the two main water channels. By separately arranging the adapter assembly 200 and the water channel component 300, the overall layout is facilitated, and the overall preparation difficulty and manufacturing cost are reduced.

[0145] In this embodiment, the valve assembly 100 can be a conventional multi-way control valve body, which generally has five functional positions: water supply, backwash, regeneration, water replenishment, and forward wash. The three functional waterways for water supply, water replenishment, and forward wash have forward flow, i.e., the flow direction of the waterways in the resin tank 400 is the same as the soft water waterway in this embodiment. The two functional waterways for backwash and regeneration have reverse flow, i.e., the flow direction of the waterways in the resin tank 400 is the same as the regeneration waterway in this embodiment. The multi-way valve body switches between the various waterways via the valve core 140 therein. 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 flow direction of the waterways.

[0146] Understandably, the reference Figure 18 As shown, the resin tank 400 in each embodiment of the present application can adopt a conventional resin tank structure, that is, it has a barrel structure for filling resin particles, and also has an independent central tube 410 in the barrel body. The resin filling part 420 is located at the outer part of the central tube 410, and the water channel realizes softening and other functions by contacting the resin particles in the resin tank 400.

[0147] According to one embodiment of the present invention, referring to Figure 43-45 The adapter assembly 200 and the valve assembly 100 are arranged side by side above the water channel component 300 along the length direction of the housing 10, and the valve assembly 100 is connected to the external water channel through the rear cover plate 12 of the housing 10.

[0148] It will be appreciated that in this embodiment, arranging the adapter assembly 200 and the valve assembly 100 side by side along the length of the housing 10 above the water channel member 300 can reduce the space occupied in the width direction, making the water softener more compact and effectively reducing the size of the water softener. This design allows the various components of the water softener to be arranged more closely together, thus saving space and making the water softener more suitable for installation in space-constrained environments such as homes and offices.

[0149] In this embodiment, the valve assembly 100 is connected to the external water circuit via the rear cover 12 of the housing 10. This means that the water softener's water inlet and outlet are located on the rear cover 12 of the housing 10, minimizing the space occupied by the water softener. This is particularly important for installations in limited spaces, such as kitchens and bathrooms. By placing the water inlet and outlet on the rear, space is effectively saved, making it easier to integrate the water softener into existing layouts without requiring long pipes for water connections.

[0150] According to one embodiment of the present invention, referring to Figure 43-45 The water softener further includes a control box 30 , which is connected to the valve assembly 100 , and the control box 30 , the adapter assembly 200 and the valve assembly 100 are arranged side by side above the water channel component 300 along the length direction of the housing 10 .

[0151] It will be appreciated that in this embodiment, the water softener typically also includes a control box 30, which is used to control the operation and operation of the water softener. The control box 30 is typically connected to the valve assembly 100, controlling the opening and closing of the valve assembly 100 via control signals, thereby adjusting the operating state of the water softener. To achieve a more compact overall structure of the water softener, the control box 30, adapter assembly 200, and valve assembly 100 are arranged side by side along the length of the housing 10, above the water channel member 300. This design maximizes the space within the housing 10, tightly integrating the various components, reducing the widthwise occupied space, and further reducing the size of the water softener.

[0152] Through this layout, the key components of the water softener can be closely matched in a limited space, improving the overall performance and reliability of the water softener. At the same time, this design also facilitates the maintenance and repair of the water softener, making it easier for users to operate and maintain it.

[0153] According to one embodiment of the present invention, referring to Figure 43-45 The housing 10 includes a detachable top plate 16 , which is disposed above the control box 30 , the adapter assembly 200 and the valve assembly 100 .

[0154] It is understood that in this embodiment, the housing 10 includes a detachable top plate 16, which is installed above the control box 30, the adapter assembly 200, and the valve assembly 100 to protect these key components. The design of the top plate 16 effectively prevents dust, debris, and other foreign matter from entering the interior of the water softener during normal operation, keeping the equipment clean and operating normally. At the same time, the detachable design of the top plate 16 also facilitates the repair and maintenance of the water softener. When the control box 30, the adapter assembly 200, or the valve assembly 100 needs to be repaired, replaced, or adjusted, the user only needs to simply open the top plate 16 to easily operate the interior of the water softener. This design makes the repair process more efficient and convenient.

[0155] Furthermore, placing the top plate 16 directly over the control box 30, adapter assembly 200, and valve assembly 100 also 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 various environments.

[0156] According to one embodiment of the present invention, referring to Figure 43-45 The water softener also includes a salt tank 500, which is arranged on a side of the accommodating space close to the front panel 11 of the shell 10. The salt tank 500 is connected to the adapter assembly 200 through a salt absorption pipe 550. The salt tank 500 is filled with water and absorbs salt through the regulation of the valve assembly 100, and the adapter assembly 200 is arranged on a side of the valve assembly 100 close to the salt tank 500.

[0157] It will be appreciated that in this embodiment, for ease of use and maintenance, the salt tank 500 is typically positioned on the side of the housing 10 near the front panel 11. This placement of the salt tank 500 allows for easier addition or replacement of salt, while also facilitating cleaning and maintenance. The salt tank 500 is connected to the adapter assembly 200 via a salt intake tube 550. The salt intake tube 550 transports salt from the salt tank 500 to the adapter assembly 200 for use in the water softener's salt solution preparation and regeneration process. The adapter assembly 200 is typically positioned on the side of the valve assembly 100 near the salt tank 500, reducing the length of the salt intake tube 550 and making the water softener more compact. This design reduces resistance and pressure loss in the salt intake tube 550, improving salt solution delivery efficiency while also reducing the size of the water softener.

[0158] According to one embodiment of the present invention, referring to Figure 43-45 The water softener also includes an overflow pipe 40. The rear cover plate 12 of the shell 10 is provided with a through-plate joint 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 box 500, and the other end is suitable for communicating with the outside through the through-plate joint 103.

[0159] It is understandable that, in this embodiment, an overflow port can be provided on the back side of the salt box 500, and the overflow port is connected to the outside through the overflow pipe 40. When the water level in the salt box 500 is too high, the excess water can be discharged through the overflow pipe 40, thereby preventing water from overflowing directly from the top of the salt box 500 and causing moisture and pollution inside the equipment or the surrounding environment.

[0160] 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 direction of the shell 10, the first end of the overflow pipe 40 is connected to the overflow port of the salt box 500. Such a design can guide the water that may overflow to a safe drainage position through the pipe, thereby ensuring the stability of the liquid level in the salt box 500; by providing a through-plate joint 103 on the rear cover plate 12 of the water softener, it is connected to the second end of the overflow pipe 40, which is used to guide the overflow water to the sewer or other suitable location for discharge, thereby ensuring the sealing and effectiveness of the entire anti-overflow structure; in addition, by arranging the overflow pipe 40 horizontally from front to back, the thickness of the water softener is reduced, which is more conducive to miniaturized design and can adapt to various narrow installation spaces, thereby improving the user's installation flexibility and usage experience.

[0161] According to one embodiment of the present invention, referring to Figure 43-45 A support member 17 is provided in the housing 10 , and the support member 17 connects the resin tank 400 and the salt box 500 , and the support member 17 is provided above the salt box 500 .

[0162] It will be appreciated that in this embodiment, a support member 17 is provided within the housing 10. The support member 17 is primarily used to secure and support the resin tank 400 and the salt tank 500 within the water softener. This prevents the water softener from shaking or shifting during operation, thereby ensuring the normal operation and service life of the water softener.

[0163] Support member 17 connects the resin tank 400 and the brine tank 500 and is positioned above the brine tank 500. This design optimizes the spacing between the various components and pipes within the water softener, preventing interference and friction. Furthermore, the position of support member 17 makes the water softener more compact and stable, reducing noise and vibration during operation.

[0164] Furthermore, the support member 17 may be provided with a snap-fit ​​structure for snapping onto the shell plate 13, thereby forming a unitary structure of the water softener and enhancing its overall performance and stability. The support member 17 may also be provided with a mounting portion for mounting and securing the control box 30 to prevent it from loosening or shaking.

[0165] According to one embodiment of the present invention, referring to Figure 43-45The shell 10 includes a plurality of detachably mounted 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 , the water channel component 300 , the valve assembly 100 and the adapter assembly 200 .

[0166] It will be appreciated that, in this embodiment, the housing 10 includes multiple shell panels 13, which are detachably connected to each other. The multiple shell panels 13 can be further subdivided into a front panel 11, a rear cover 12, an upper top panel 16, a lower bottom panel, and side panels, which together enclose a storage space. The detachable connection between the multiple shell panels 13 facilitates maintenance and replacement of the water softener. When maintenance or replacement of water softener components is required, the user only needs to remove the corresponding shell panel 13. This also makes the water softener more flexible and adaptable to different installation environments and usage requirements.

[0167] In one optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400. For example, the lower base plate and the side plates 21 on either side are detachably connected to the resin tank 400. This facilitates user maintenance and replacement of the resin tank 400 and prevents accidental separation of the housing 10 and the resin tank 400 during operation of the water softener, thereby ensuring system stability and safety. In another optional embodiment, at least one shell plate 13 is detachably connected to the valve assembly 100, facilitating installation and securing of the valve assembly 100, as well as ease of disassembly and maintenance.

[0168] In other embodiments, at least one shell plate 13 is detachably connected to the salt box 500, for example, the lower base plate and the front cover plate are detachably connected to the salt box 500, so as to facilitate the user to maintain and replace the salt box 500, and ensure that the shell 10 and the salt box 500 will not be accidentally separated during the operation of the water softener, thereby ensuring the stability and safety of the system.

[0169] According to one embodiment of the present invention, referring to Figure 43-45 Side plates 21 are extended on both sides of the resin tank 400 or the water channel component 300. The side plates 21 are suitable for connecting with the housing 10. The side plates 21 define an installation cavity, and the valve assembly 100 and the adapter assembly 200 are both arranged in the installation cavity.

[0170] In an optional embodiment, side panels 21 extend along the height of the housing 10 on either side of the resin tank 400. The connection between the side panels 21 and the housing 10 secures the resin tank 400 within the water softener, ensuring its stability. Furthermore, the mounting cavity defined by the side panels 21 provides a dedicated space for the waterway component 300, valve assembly 100, and adapter assembly 200, allowing for their orderly arrangement and installation.

[0171] In an alternative embodiment, side panels 21 extend along the height of the housing 10 on either side of the water channel member 300. The connection between the side panels 21 and the housing 10 securely holds the water channel member 300 and the resin tank 400 within the water softener, ensuring their stability. Furthermore, the mounting cavity defined by the side panels 21 provides a dedicated space for the valve assembly 100 and adapter assembly 200, allowing for their orderly arrangement and installation.

[0172] Placing the water channel member 300 within the installation cavity makes the water softener's water system more centralized and compact, facilitating maintenance and operation. The design of the installation cavity also effectively isolates the water channel member 300 from other components, preventing interference. Therefore, the placement of the side panels 21 and the confinement of the installation cavity provide improved connectivity and support, creating an organized space for the installation of the water channel member 300. This design optimizes the water softener's structural layout, enhancing its stability and ease of use.

[0173] According to one embodiment of the present invention, referring to Figure 16 、 Figure 18 and Figure 43 The water softener includes a plurality of resin tanks 400 arranged side by side. The number of the mounting openings 302 is plural, and the plurality of resin tanks 400 are arranged side by side in the accommodating space along the length direction of the housing 10 .

[0174] It is understandable that 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 includes a plurality of resin tanks 400, and the plurality of resin tanks 400 are arranged side by side on the back side of the salt tank 500 along the length of the water softener. This parallel layout can make full use of the internal space of the water softener and avoid the increase in overall thickness caused by the stacking of components. By arranging the resin tank 400 and the salt tank 500 side by side, rather than vertically or cross-stacked, the thickness of the entire water softener is effectively reduced while maintaining functional integrity, meeting the requirements of ultra-thin design, and is particularly suitable for environments with limited installation space. In addition, the resin tank 400 and the salt tank 500 are compactly arranged side by side, reducing the complexity and length of the internal pipe connection, which not only helps to improve the water exchange efficiency, but also reduces the equipment manufacturing cost and potential failure rate, further improving the product's user experience and durability.

[0175] In particular, if multiple resin tanks 400 are used in parallel, when one resin tank 400 reaches saturation, the remaining unsaturated resin tanks 400 can continue ion exchange, ensuring the softener can continuously provide softened water and improving system stability and reliability. Furthermore, by adjusting the operating order of the resin tanks 400 or configuring resin tanks 400 of different capacities, the water flow rate and softening effect can be flexibly adjusted according to actual needs, achieving precise control of the water softening process.

[0176] Therefore, this embodiment, through the reasonable design of the number and layout of the resin tanks 400, not only achieves the ultra-thin transformation of the water softener, but also improves its functionality, ease of use and work efficiency, and significantly improves the user experience.

[0177] In an optional embodiment, there are multiple installation openings 302, which are spaced apart along the length of the water channel member 300. To avoid complicating the flow channel 303 structure, the flow channel 303 is typically connected as a single resin tank 400. When each resin tank 400 holds the same number of resin particles, it often requires a larger opening. However, a larger opening will affect the contact between the raw water and the resin, and also cause the entire system to occupy a larger space in the width direction. In this embodiment, due to the separate arrangement of the water channel component 300 and the adapter assembly 200, the structure of the water channel component 300 is simple, and an installation port 302 is constructed on the water channel component 300, and the installation port 302 can be connected to the resin tank 400, so that multiple installation ports 302 can be arranged in the length direction of the water channel component 300 for installing the resin tank 400. The installation of multiple resin tanks 400 makes it possible to achieve the same number of resin particles when required through the distribution of multiple resin tanks 400, which makes the volume of a single resin tank 400 smaller, and thus makes the overall space occupied by the water channel component 300 in the width direction small.

[0178] Specifically, the water channel member 300 has a first water channel and a second water channel. The first water channel is connected to the resin filling portion 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 fluid to enter the resin filling portion 420 of each resin tank 400 through the first water channel. Similarly, the working fluid can also enter the central tube 410 of each resin tank 400 through the second water channel.

[0179] In specific applications, in some embodiments, the number of mounting openings 302 on the water channel member 300 is two, and the two mounting openings 302 are spaced apart along the extension direction of the water channel member 300. Of course, in other embodiments, the number of water channel members 300 can also be three, four, etc. The embodiments of this application and the accompanying drawings are described using an example in which there are two mounting openings 302.

[0180] According to one embodiment of the present invention, referring to Figure 16-Figure 18 The water channel component 300 is constructed with a first connection end 330 and a second connection end 340 that are connected to the installation port 302. The adapter assembly 200 is connected to the water channel 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 multiple installation ports 302.

[0181] The water channel member 300 includes a first connection end 330 and a second connection end 340 that communicate with the installation port 302. The adapter assembly 200 is connected to the water channel member 300 via the first connection end 330 and the second connection end 340. The first connection end 330 can realize the input and output of the working fluid, and the second connection end 340 can also realize the input and output of the working fluid. The adapter assembly 200 switches the water channel flow direction by controlling whether the input working fluid enters through the first connection end 330 or the second connection end 340. The connection between the connection port and the water channel member 300 facilitates installation and subsequent maintenance and replacement, thereby reducing user costs.

[0182] Understandably, the integration of several components and channels into the water conservancy board complicates maintenance and increases the cost of replacing the water channel member 300. In this embodiment, the adapter assembly 200 connects to the water channel member 300 via a connection port, enabling flow control of the water channel through the adapter assembly 200 and communication with the resin tank 400 through the water channel member 300. This allows for prompt repairs if problems arise with either component, reducing both the difficulty of repair and the cost of replacement.

[0183] In the specific configuration, the first connection end 330 and the second connection end 340 are both protruding, and are connected to the adapter assembly 200 through the protruding ports to achieve connection and positioning. It can be understood that the water channel member 300 is an overall plate-like structure, and the adapter assembly 200 is arranged on the water channel member 300. During assembly, it is necessary to align the positions of the connection ports to achieve assembly. In this embodiment, the first connection end 330 and the second connection end 340 are protruding, which makes it easier to find the assembly position during assembly and facilitates the assembly and disassembly of the adapter assembly 200.

[0184] In specific applications, the first connection end 330 and the second connection end 340 are arranged side by side along the width direction of the water channel component 300. This approach is beneficial to the layout of the adapter assembly 200 and the assembly connection between the adapter assembly 200 and the water channel component 300.

[0185] According to an embodiment provided by the present invention, the first connection end 330 and the second connection end 340 are located on the same one of the multiple installation ports 302. The multiple installation ports 302 are used to install resin tanks 400. Each resin tank 400 can be connected to the first connection end 330 and the second connection end 340 to realize the input or output of the working fluid. In this embodiment, the first connection end 330 and the second connection end 340 are both set on the same installation port 302, which allows sufficient space on the remaining installation ports 302 to accommodate the assembly of other components, thereby improving the flexibility of the layout of each component.

[0186] In the specific setting, the water channel component 300 has two installation openings 302, and the two installation openings 302 are arranged at intervals along the length direction of the flow channel 303 component. The two installation openings 302 are both set on one of the installation openings 302, which forms an avoidance space on the other installation opening 302, and the main body 301 of the valve assembly 100 and the adapter assembly 200 can be set in the avoidance space, so that the valve system in this embodiment has a compact structure, shortens the width, and is conducive to miniaturization design.

[0187] In specific applications, the first connection end 330 and the second connection end 340 are located on the side of one mounting port 302 close to the other mounting port 302. This can reduce the distance difference between the respective port positions and the center of the mounting ports 302 on both sides, thereby minimizing the path difference of the water channel to the center position of the mounting ports 302 on both sides. It is understandable that the longer the path of water flowing through the pipeline, the greater the loss in output performance. This method can achieve a compact layout of the entire component and reduce the difference in water delivery capacity caused by the path difference on both sides, thereby achieving a compact overall structural layout and taking into account performance.

[0188] In some embodiments, the number of mounting ports 302 is greater than two. In this case, the multiple mounting ports 302 are spaced apart along a straight line, and the mounting port 302 with the first connection end 330 and the second connection end 340 is located at an end position. When the valve system is installed, it is usually located inside the entire device housing 10 to achieve control of the entire waterway. The internal space is limited, which makes installation and subsequent maintenance difficult. In this embodiment, the first connection end 330 and the second connection end 340 are located on the mounting port 302 at one of the ends. This facilitates layout and can well expose the connection position to facilitate installation and removal. In addition, because the connection port is offset to the mounting port 302 at the end, the remaining mounting ports 302 have more space to avoid, which facilitates the layout of component connections and improves its layout flexibility.

[0189] Specifically, the water channel member 300 is constructed with a first water channel and a second water channel. The first connecting end 330 is connected to the first water channel, and the 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 portion 420 of the resin tank 400, while 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 water channels provide connectivity with each resin tank 400, simplifying the structure of the water channel connection flow channel 303 and reducing the difficulty and cost of manufacturing the water channel member 300.

[0190] According to an embodiment provided by the present invention, a valve assembly 100 has a water channel input end, a water channel output end, and a water channel connection end. The water channel input end and the water channel output end are located on one side of the valve assembly 100, and the water channel connection end is located on the other side of the valve assembly 100. The adapter assembly 200 is connected to the water channel connection end to connect the adapter assembly 200 with the various water channels within the valve assembly 100. The valve assembly 100 is generally used for the access of water channels and the output of treated water channels. The water channel input end is generally connected to the water inlet pipe 112, and the water channel output end is connected to a water-using device or a water terminal. However, in household scenarios, the installation space is generally limited and daily maintenance needs to be facilitated. In this embodiment, the water channel input end and the water channel output end are on the same side of the valve assembly 100, which facilitates the connection of the inlet and outlet water channels and facilitates installation and removal in a limited space. In addition, the connection end is arranged on the other side, spatially separating the input and output water channels from the connection end, which can facilitate the connection layout of the valve assembly 100.

[0191] In the specific setting, one side of the valve assembly 100 and the other side of the valve assembly 100 are arranged relative to each other, so that one side of the valve assembly 100 is connected to the water inlet pipe 112 and the water outlet pipe 113, and the side opposite to the water inlet pipe 112 and the water outlet pipe 113 is connected to the adapter assembly 200. The water path passing through the valve assembly 100 flows in a roughly straight line as a whole, which can reduce the flow path of the water path and thereby reduce the energy loss of the water path during the flow process.

[0192] According to one embodiment of the present invention, referring to Figure 43-45 The valve assembly 100 is connected to a water inlet pipe 112 and a water outlet pipe 113 , which extend along the length direction of the shell 10 , and one end of the water inlet pipe 112 and the water outlet pipe 113 extends out of the rear cover plate 12 of the shell 10 .

[0193] It is understood that in this embodiment, the valve assembly 100 is connected to the external water circuit via the water inlet pipe 112 and the water outlet pipe 113. That is, the water inlet and water outlet of the water softener are arranged on the rear cover plate 12 of the housing 10. At the same time, the valve assembly 100 can also be arranged on the side close to the rear cover plate 12 to reduce the length of the water inlet pipe 112 and the water outlet pipe 113, facilitate the arrangement of the water inlet pipe 112 and the water outlet pipe 113, and minimize the space occupied by the water softener. This is particularly important for installation in environments with limited space, such as kitchens and bathrooms. By arranging the water inlet and water outlet on the back, space can be effectively saved, making it easier for the water softener to be embedded in the existing layout, without having to set up long pipes to achieve water connection.

[0194] In the related art, the control of the water softener valve assembly 100 and the passage control of the adapter assembly 200 require separate electrical control components for control, resulting in a complex structure and large size of the entire control system, which also increases the failure rate, maintenance difficulty and repair cost.

[0195] According to one embodiment of the present invention, referring to Figure 1-Figure 5 As shown, the valve assembly 100 includes a valve body 110, a valve core 140, a transmission mechanism 141 and a driving part 142. The valve core 140 is connected to the driving part 142 through the transmission mechanism 141. The adapter assembly 200 is provided with a sewage path 2107 and a pressure rod. The driving part 142 is suitable for driving the valve core 140 to rotate relative to the valve body 110 through the transmission mechanism 141 to realize the switching of different water paths, and the transmission mechanism 141 is suitable for driving the pressure rod to switch between the sewage position and the non-sewage position. In the non-sewage position, the pressure rod blocks the sewage path 2107. In the sewage position, the pressure rod is moved away to open the sewage path 2107.

[0196] It can be understood that in this embodiment, the valve body 110 is formed with a valve cavity 111, a water inlet channel 163, a water outlet channel, a salt absorption channel and a backwash channel. The valve core 140 is rotatably arranged in the valve cavity 111, and the driving part 142 is connected to the valve core 140 through a rotating mechanism. When the driving part 142 rotates, it drives the valve core 140 to rotate, so as to realize the connection between the valve cavity 111 and 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 and closing of the sewage discharge channel 2107. That is, when only one driving part 142 is provided, 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 at the same time, which simplifies the control logic, improves the control efficiency, reduces the number of control components, reduces the volume and occupied space of the water softener, and also reduces the failure rate of the water control component.

[0197] According to one embodiment of the present invention, referring to Figure 1-Figure 5 As shown, the transmission mechanism 141 includes: a driving gear 1432, which is arranged at the output end of the driving part 142; a driven gear 1431, which is engaged with the driving gear 1432, and the driven gear 1431 has at least one driving block 1433. During the rotation of the transmission mechanism 141, the driving block 1433 is suitable for abutting and pushing the pressure rod to switch between the sewage discharge position and the non-sewage discharge position; a rotating shaft 150, which is 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 path switching.

[0198] like Figure 14 、 Figure 22As shown, according to some embodiments of the present invention, the adapter assembly 200 has a sewage control assembly 250, which is arranged in the sewage water path 2107. The sewage control assembly 250 is used to control the on and off of the sewage water path 2107. The transmission mechanism 141 includes a driving gear 1432, a driven gear 1431 and a rotating shaft 150. The driving gear 1432 is arranged at the output end of the driving part 142; the driven gear 1431 is engaged with the driving gear 1432, and the driven gear 1431 has at least one driving block 1433. The driving block 1433 is used to cooperate with the sewage control assembly 250 to realize the opening of the sewage water path 2107, and the rotating shaft 150 is 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 path switching. The sewage control assembly 250 opens the sewage discharge path 2107 by interacting with the driver block 1433 on the driven gear 1431. Specifically, when sewage discharge path 2107 needs to be opened, the rotation of the driven gear 1431 causes the driver block 1433 to squeeze the sewage control assembly 250, thereby opening sewage discharge path 2107. For example, in the salt absorption position, the salt absorption path is connected, and the valve assembly 100 can transfer salt water from the salt tank 500 to the resin tank 400. The salt water displaces the calcium and magnesium ions adsorbed on the resin, reducing the resin so that it can continue to adsorb calcium and magnesium ions. The reduced wastewater enters the sewage discharge path 2107 through the adapter assembly 200. At this time, the driver block 1433 squeezes the sewage control assembly 250, opening sewage discharge path 2107 and enabling direct discharge of sewage. This enables a single driver 142 to control both water path switching and the opening of sewage discharge path 2107, simplifying the control logic.

[0199] Hard water can have a variety of impacts on daily life and household appliances. For example, it can reduce washing efficiency, accumulate in pipes, reducing water flow, impairing equipment performance and lifespan, and causing skin problems. Therefore, people often use water softeners to treat their tap water. Using water softeners can effectively remove minerals from hard water, improving water quality and enhancing the quality of life. Water softeners typically work by removing calcium and magnesium ions from water through an ion exchange process, thereby converting hard water into soft water.

[0200] Resin treatment is a common method. Resin is a polymer with a unique structure that carries a positive surface charge. When hard water passes through the resin particles, the calcium and magnesium ions in the resin attract the positive charges on the resin surface, replacing the sodium ions already on the resin. Over time, the resin particles gradually become saturated, requiring cleaning by aspirating salt water to regenerate the resin particles by replacing the adsorbed ions.

[0201] In the prior art, control valves are used to switch the water circuits to achieve the various functions of the water softener. Wastewater after cleaning the resin particles is discharged through a separate drainage channel. In other words, the switching of the water circuits and the opening of the drainage channel are controlled separately in the prior art. This increases the complexity of the control system, the number of parts required, and the manufacturing cost. Furthermore, the complex control system reduces the reliability of the entire device.

[0202] For related technical issues, see Figure 1-5 As shown, the present invention provides a water softener, which includes a valve assembly 100, an adapter assembly 200, a water channel component 300 and a resin tank 400. The valve assembly 100 includes a valve body 110, a valve core 140, a driving portion 142 and a transmission mechanism 141. The valve core 140 and the driving portion 142 are both arranged in the valve body 110. The driving portion 142 is connected to the valve core through the transmission mechanism 141, so that the valve core 140 controls the water channel switching under the drive of the driving portion 142; the adapter assembly 200 and the resin tank 400 are connected. The valve assembly 100 is connected to and located on one side of the valve assembly 100. The adapter assembly 200 has a sewage discharge passage 2107. The adapter assembly 200 cooperates with the transmission mechanism 141. The driving unit 142 is suitable for driving the transmission mechanism 141 to control the opening of the sewage discharge passage 2107. The water channel component 300 is connected to the adapter assembly 200 and is used to guide the flow of the water channel. The resin tank 400 is fixedly connected to the water channel component 300 and is used to soften the water flowing through the resin tank 400. When the water softener is in operation, the water channel flowing through the resin tank 400 has different flow directions depending on the different functions required. The water channel is specified to flow from the resin filling area at the top of the resin tank 400, then rises through the central pipe 410, and then is output as a forward circulation water channel. The water channel is specified to flow from the central pipe 410, then rises through the resin particle filling area, and then is output as a reverse circulation water channel. In a water softener, the reverse circulation waterway is typically output through sewage discharge channel 2107, which is normally closed and opened when sewage discharge is required. In this embodiment, the drive unit 142 cooperates with the transmission mechanism 141 to control the switching of the various waterways. Furthermore, while controlling the switching of the various waterways, the drive unit 142 also cooperates with the adapter assembly 200 to open sewage discharge channel 2107. This allows the opening of each waterway in the water softener and the realization of various functions of the water softener, simplifying the water softener's control system and improving its stability.

[0203] When setting specific Figure 5As shown, the transmission mechanism 141 is in transmission connection with 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 components. When the transmission mechanism 141 rotates or moves to a set position, the mating components cooperate with corresponding components on the adapter assembly 200 to open the sewage flow path 2107. When different functions of the water softener are realized, the transmission mechanism 141 can cooperate with the adapter assembly 200 to open the sewage flow path 2107, thereby realizing that a single drive unit 142 can control the realization of different functional positions of the water softener.

[0204] It is understandable that in order to realize the control of the sewage water path 2107 in the related art, it is often necessary to set up a separate control component and a corresponding control module for control, so as to realize the opening of the sewage water path 2107. The number of control components is large and the entire control system is complex. In this example, the action of the valve core 140 can be controlled by the transmission component first, thereby realizing the switching of each water path, and in the switching process of each water path, the transmission mechanism 141 can cooperate with the adapter component 200, and the opening of the sewage water path 2107 can be realized by cooperating with the adapter component 200. That is, the water path switching and the control of the sewage water path 2107 are realized by the cooperation of a drive part 142 and a transmission mechanism 141, which reduces the control components, simplifies the control system and control logic, and improves the stability of the control system.

[0205] In specific applications, raw water is introduced through the valve assembly 100 and then enters the resin tank 400 through the adapter assembly 200. The resin tank 400 is filled with resin pellets and a central tube 410. After being processed by the resin pellets in the resin tank 400, the raw water is output from the valve assembly 100 through the adapter assembly 200. The flow direction of the water channel in the resin tank 400 is controlled by the adapter assembly 200. In other words, the flow direction of the water channel in the resin tank 400 is controlled by the transmission mechanism 141 in conjunction with the adapter assembly 200, thereby controlling the forward and reverse circulation water channels in the resin tank 400.

[0206] like Figure 6 、 Figure 7As shown, according to one embodiment of the present invention, a valve assembly 100 includes a valve body 110 with a valve cavity 111 therein. The valve body 110 also includes a water inlet pipe 112, a water outlet pipe 113, a tank inlet pipe 114, and a tank outlet pipe 115, all of which are connected to the valve cavity 111. A valve seat 116 is located within the valve cavity 111. A valve core 140 is disposed on the valve seat 116 and positioned within the valve cavity 111. The valve core 140 switches relative to the valve seat 116 between a service position, a salt absorption position, a bypass position, a backwash position, and a water replenishment position, thereby defining a service waterway, a salt absorption position, a bypass position, a backwash position, and a water replenishment position. In this embodiment, when the water softener is in operation, it primarily has a service position, a salt absorption position, a bypass position, a backwash position, and a water replenishment position. Each position corresponds to a waterway, and the different functions of the water softener are achieved by controlling each waterway.

[0207] In specific settings, the valve assembly 100 is used to control the flow direction of water (including raw water, soft water, sewage, etc.) in the water softener to achieve corresponding functions. Figure 29 As shown, the water softener also includes a salt tank 500. As described above, the resin tank 400 is filled with resin particles. The resin particles are used to adsorb metal ions such as calcium and magnesium in the raw water to reduce the hardness of the raw water. The resin tank 400 is connected to the valve assembly 100. The salt tank 500 contains salt water, and the salt tank 500 is connected to the valve assembly 100. The salt tank 500 and the resin tank 400 are connected through the valve assembly 100. The salt tank 500 is suitable for providing salt water to the resin tank 400 to clean the reduced resin so that the resin can continue to adsorb calcium and magnesium ions. The valve assembly 100 is used to control the flow direction of water. For example, the valve assembly 100 can control the flow of raw water into the resin tank 400 for filtration to reduce the hardness of the water and form soft water.

[0208] It is understandable that if Figure 4-Figure 12 As shown, the water inlet pipe 112 is adapted to connect to a water source to provide raw water; the water outlet pipe 113 is adapted to connect to a user end, thereby providing water to 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, the water softener switches to a connected state at corresponding positions to deliver water to the corresponding locations. Thus, by rotating the valve core 140 to the desired position, the corresponding water channel switches to a connected state, thereby controlling the flow direction of water within the water softener and simplifying the control logic. Furthermore, controlling the water channels within the water softener through the valve assembly 100 improves the integration of the water softener's control structure. In some embodiments, the valve chamber 111 has a circular cross-section, and the valve seat 116 is cylindrical and located at the center of the valve chamber 111.

[0209] At the service location, such as Figures 19-22As shown, at least the service waterway is in a connected state, and the valve assembly 100 can deliver raw water to the resin tank 400, so that the resin particles can absorb the calcium and magnesium ions in the raw water to produce soft water. Figure 25-29 As shown, at least the brine absorption line 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 replace the calcium and magnesium ions adsorbed on the resin to restore the resin so that the resin can continue to adsorb calcium and magnesium ions. Figure 23 、 Figure 24 As shown, at least the bypass waterway is in a connected state, and the valve assembly 100 can directly deliver raw water to the user end. It is understandable that users have various water needs and different water hardness requirements in different scenarios.

[0210] For example, when flushing a toilet, the influence of water hardness can be ignored and the user can use raw water for flushing. At this time, the valve core 140 is switched to the bypass position to provide raw water for flushing the toilet, which can reduce the resin filtration process and thus reduce the consumption of resin. Figures 31-34 As shown, at least the backwash waterway is in a connected state. At this time, valve assembly 100 delivers water to resin tank 400 to flush the resin, remove broken resin, and increase the spacing between resin particles. After switching to the service position, the resin is fully exposed to raw water to adsorb calcium and magnesium ions, improving filtration efficiency. In the replenishment position, at least the replenishment waterway is in a connected state. Valve assembly 100 is suitable for delivering water to brine tank 500 to replenish brine.

[0211] It can be understood that in this embodiment, the valve core 140 is driven to rotate by the driving unit 142 to switch between the service position, the salt absorption position, the bypass position, the backwash position and the water replenishment position. The valve core 140 and the valve seat 116 define corresponding water paths to control the flow direction of water in the water softener, simplifying the control logic and reducing operating costs.

[0212] 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 in communication with the tank inlet pipe 114, and the water inlet pipe 112 is in communication with both the first water inlet cavity 130 and the second water inlet cavity 132. The valve seat 116 has a bypass cavity 133 in communication with the water outlet pipe 113 and is spaced apart from the second water inlet cavity 132. The tank inlet cavity 131 is in communication with the first water inlet cavity 130 or the second water inlet cavity 132 via 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 collectively define a service waterway. The raw water is delivered to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112 , flows to the tank inlet chamber 131 through the valve core 140 , and is delivered to the inlet of the resin tank 400 through the tank inlet pipe 114 .

[0213] The bypass chamber 133 communicates with either the first water inlet chamber 130 or the second water inlet chamber 132 via the valve core 140. The first and second water inlet chambers 130, 132, valve core 140, and bypass chamber 133 collectively define a bypass waterway. Raw water is delivered to the first and second water inlet chambers 130, 132 via the water inlet pipe 112, flows through the valve core 140 into the bypass chamber 133, and finally flows out through the water outlet pipe 113 to be provided to the user. This allows the water softener to deliver raw water to the resin tank 400 for filtration and softening via the service waterway, while also providing raw water to the user via the bypass waterway, enhancing its flexibility.

[0214] According to some embodiments of the present invention, the water outlet pipe 113 and the tank outlet pipe 115 are connected through a bypass check valve 137 to allow one-way conduction 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, and the water outlet pipe 113 is connected to the tank outlet pipe 115. The soft water produced by the resin tank 400 flows to the water outlet pipe 113 through the tank outlet pipe 115, and is then transported to the user end. In this way, the water flowing in the water outlet pipe 113 includes the soft water produced in the resin tank 400 and the raw water flowing out through the bypass chamber 133. The bypass check valve 137 can be arranged in the water outlet pipe 113 or in the tank outlet pipe 115. The bypass check valve 137 can be unidirectional, so that water flows in a unidirectional direction from the tank outlet pipe 115 to the water outlet pipe 113, so as to prevent the water in the water outlet pipe 113 from flowing back into the resin tank 400. The position where the bypass chamber 133 is connected to the water outlet pipe 113 is between the outlet of the bypass check valve 137 and the outlet of the water outlet pipe 113, so as to prevent the raw water in the bypass chamber 133 from flowing to the tank outlet pipe 115. As Figure 5 and Figure 23As shown, in some embodiments, the valve assembly 100 further includes a flow meter 183, which is disposed in the outlet pipe 113 and closer to the outlet of the outlet pipe 113 relative to the position where the bypass chamber 133 communicates with the outlet pipe 113. The flow meter 183 is used to detect the water flow output by the outlet pipe 113. Figure 23 As shown, the flow meter 183 is inserted into the water outlet pipe 113 and is fixedly connected to the water outlet pipe 113 by plugging.

[0215] like Figure 14 、 Figure 22 As shown, according to some embodiments of the present invention, the adapter assembly 200 has a sewage control assembly 250, which is arranged in the sewage water path 2107. The sewage control assembly 250 is used to control the on and off of the sewage water path 2107. The transmission mechanism 141 includes a driving gear 1432, a driven gear 1431 and a rotating shaft 150. The driving gear 1432 is arranged at the output end of the driving part 142; the driven gear 1431 is engaged with the driving gear 1432, and the driven gear 1431 has at least one driving block 1433. The driving block 1433 is used to cooperate with the sewage control assembly 250 to realize the opening of the sewage water path 2107, and the rotating shaft 150 is 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 path switching. The sewage control assembly 250 opens the sewage discharge path 2107 by interacting with the driver block 1433 on the driven gear 1431. Specifically, when sewage discharge path 2107 needs to be opened, the rotation of the driven gear 1431 causes the driver block 1433 to squeeze the sewage control assembly 250, thereby opening sewage discharge path 2107. For example, in the salt absorption position, the salt absorption path is connected, and the valve assembly 100 can transfer salt water from the salt tank 500 to the resin tank 400. The salt water displaces the calcium and magnesium ions adsorbed on the resin, reducing the resin so that it can continue to adsorb calcium and magnesium ions. The reduced wastewater enters the sewage discharge path 2107 through the adapter assembly 200. At this time, the driver block 1433 squeezes the sewage control assembly 250, opening sewage discharge path 2107 and enabling direct discharge of sewage. This enables a single driver 142 to control both water path switching and the opening of sewage discharge path 2107, simplifying the control logic.

[0216] When setting specific Figure 5As shown, the drive unit 142 is a drive motor, which is fixedly connected to the valve body 110 and can be fixed to the valve body 110 via screws. The driven gear 1431 is larger than the driving gear 1432. The two gears are meshed, and the drive motor drives the driving gear 1432 to rotate. The driving 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 in the valve core 140 to rotate. The transmission ratio between the driving gear 1432 and the transmission gear is greater than 1, that is, the number of teeth on the driving gear 1432 is greater than that on the transmission gear, thereby amplifying the driving torque and providing sufficient power to drive the rotating shaft 150 and the moving plate 160 to rotate.

[0217] like Figure 5 、 Figure 11 and Figure 12 As shown, according to some embodiments of the present invention, valve core 140 includes a rotor 160, which is fixedly connected to a rotating shaft 150. Rotating shaft 150 drives rotor 160 to rotate. Rotating blade 160 is disposed on valve seat 116 and cooperates with valve seat 116 to define a service waterway, a brine absorption waterway, a bypass waterway, a backwash waterway, and a replenishment waterway. A drive unit 142 is connected to valve body 110, and rotating shaft 150 is rotatably connected to valve body 110. Rotating shaft 150 is in transmission connection with drive unit 142. Rotating blade 160 is fixedly connected to rotating shaft 150, and rotating shaft 150 drives rotor 160 to rotate. Rotating blade 160 is adapted to be attached to the top of valve seat 116. Rotating shaft 150 is driven by a drive assembly to rotate, which drives rotor 160 to rotate, causing rotor 160 to cooperate with valve seat 116 to define corresponding waterways. For example, the movable plate 160 is rotated so that the movable plate 160 is matched with the tank inlet cavity 131. Thus, the first water inlet cavity 130, the second water inlet cavity 132, the movable plate 160 and the tank inlet cavity 131 jointly define a service waterway.

[0218] 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 cover 118. The valve cavity 111 is provided in the valve body portion, and one side of the valve cavity 111 is open. The rotating shaft 150 is provided in the valve cavity 111, one end of the rotating shaft 150 is located in the valve cavity 111, and the other end of the rotating shaft 150 is located outside the valve cavity 111. The gear assembly 143 and the drive motor are both located outside the valve cavity 111. The gear assembly 143 is formed by the drive gear 1432 meshing with the transmission gear, and the drive motor is the drive portion 142. The valve plug cover 118 is provided on the open end of the valve cavity 111 to seal the valve cavity 111. The rotating shaft 150 is provided on the valve plug cover 118, and the gear assembly 143 is located outside the valve cavity 111. As shown Figure 6As shown, a receiving groove 117 is provided on the valve body, and the drive motor is suitable for being received in the receiving groove 117. A valve plug cover 118 is suitable for covering the receiving groove 117, and the output shaft of the drive motor is passed through the valve plug cover 118, and one end of the drive motor is abutted against and fixedly connected to the valve plug cover 118.

[0219] 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 the drive assembly, and the vertical shaft 151 is disposed in 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 movable plate 160. The connecting disc 152 is disc-shaped to match the movable plate 160. The diameter of the connecting disc 152 can be less than or equal to the diameter of the movable plate 160. In some embodiments, a pressure block is provided on the side facing the valve plug cover 118. The pressure block is located in the valve cavity 111 and abuts against the connecting disc 152 to limit the rotating shaft 150 in the axial direction.

[0220] like Figure 5 and Figure 11 As shown, according to some embodiments of the present invention, a first locking portion 153 is provided on the connecting disk 152, and a second locking portion 167 cooperating with the first locking portion 153 is provided on the movable plate 160. One of the first locking portion 153 and the second locking portion 167 is a groove body, and the other is a protrusion. The first locking portion and the second locking portion cooperate to circumferentially limit the movable plate 160, so that the rotating shaft 150 can drive the movable plate 160 to rotate.

[0221] There can be multiple first and second clips, and multiple first clips are spaced apart along the circumferential direction of the connecting disk 152, and multiple second clips are spaced apart along the circumferential direction of the moving piece 160. The multiple first clips include a first positioning portion, and the multiple second clips include a second positioning portion. The first positioning portion is adapted to the second positioning portion to position the relative position of the moving piece 160 and the connecting disk 152 in the circumferential direction, so as to avoid misalignment of the rotating shaft 150 and the moving piece 160 during the assembly process. For example, Figure 11 As shown, there are four second latches, three of which are grooves and one is a protrusion. There are also four first latches, three of which are protrusions and one is a groove. The first latches, which are grooves, mate with the second latches, which are protrusions, to circumferentially position the movable plate 160 and the connecting plate 152, uniquely determining their relative positions in the circumferential direction for ease of assembly.

[0222] See also 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 cover 118. The control plate 119 is sleeved on the rotating shaft 150 and is located between the valve plug cover 118 and the gear assembly 143. The control plate 119 is provided with a Hall sensor 1191, and the gear assembly 143 is provided with a magnetic member. The Hall sensor 1191 is used to sense the position of the magnetic member. Therefore, the drive motor can be controlled based on the position of the magnetic member detected by the Hall sensor 1191, thereby controlling the rotation angle of the movable plate 160 to rotate the movable plate 160 to the corresponding position.

[0223] like Figure 5 As shown, in some embodiments, there can be multiple Hall sensors 1191, and the multiple Hall sensors 1191 are spaced apart along the circumferential direction of the rotating shaft 150. The positions of the multiple Hall sensors 1191 correspond to the service position, the salt absorption position, the bypass position, the backwash position and the water replenishment position, respectively. When the magnetic part moves to the position closest to one of the Hall sensors 1191, the valve core 140 switches to the corresponding position. For example, the position of one of the multiple Hall sensors 1191 corresponds to the service position. When the magnetic part moves to the position closest to the Hall sensor 1191, the valve core 140 switches to the service position. The positive projection of the movement trajectory of each Hall sensor 1191 and the magnetic part on the control board 119 can coincide with each other to improve the detection accuracy of the Hall sensor 1191. When the valve core 140 switches to the service position, the magnetic part is opposite to the corresponding Hall sensor 1191. See. Figure 5 As shown, the valve assembly 100 further includes a cover 101, which is mounted on and fixedly connected to the valve body 110, providing sealing and protection. A mounting space is defined between the cover 101 and the valve body 110, within which the open end of the valve seat 116 is located. The drive assembly and control board 119 are housed.

[0224] 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 stator 170, which is attached to the valve seat 116 and sandwiched between the movable plate 160 and the valve seat 116. The stator 170 is fixed relative to the valve seat 116, and the movable plate 160 is rotatable relative to the stator 170. The stator 170 can separate the movable plate 160 from the valve seat 116 to prevent the stator 170 from causing wear to the valve seat 116 during rotation, thereby extending the service life of the valve body 110. In addition, the stator 170 is easily replaceable, which is convenient for later maintenance. Figure 8As shown, the stator 170 is provided with a fixed bypass hole 171 corresponding to and communicating with the bypass chamber 133. The movable plate 160 cooperates with the stator 170 and the valve seat 116 to define a service waterway, a brine absorption channel, a bypass waterway, a backwash waterway, and a water replenishment channel. Specifically, the first water inlet chamber 130, the second water inlet chamber 132, the movable bypass hole 162, the fixed bypass hole 171, and the bypass chamber 133 collectively define the bypass waterway. The stator 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 chamber 132, and the fixed tank inlet hole 174 communicates with the tank inlet chamber 131.

[0225] like Figure 5 and Figure 10 As shown, in some embodiments, a sealing gasket 180 is provided between the stator 170 and the valve seat 116. The shape of the sealing gasket 180 is the same as that of the stator 170, or the shape of the sealing gasket 180 is the same as that of the top surface of the valve seat 116. This allows the stator 170 and the valve seat 116 to be sealed to prevent water seepage, and also allows the stator 170 to be fixed relative to the valve seat 116 to prevent the stator 170 from sliding along the movable plate 160. The sealing gasket 180 may be a rubber member that can deform to a certain extent to fit tightly against the valve seat 116 and the stator 170 to prevent water seepage.

[0226] like Figure 6 and Figure 9 As shown, according to some embodiments of the present invention, a first fixing portion 1111 is provided on the inner wall of the valve cavity 111, and a second fixing portion 172 is provided on the periphery of the stator 170. The second fixing portion 172 is engaged with the first fixing portion 1111 to position the stator 170 in the circumferential direction and prevent the stator 170 from rotating relative to the valve seat 116. One of the second fixing portion 172 and the first fixing portion 1111 is a groove, and the other is a protrusion. Figure 6 and Figure 9 In the example, the first fixing portion 1111 is a protrusion, and the second fixing portion 172 is a groove.

[0227] 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 second fixing portions 172 are spaced apart along the circumferential direction of the stator 170. Among the multiple first fixing portions 1111, the width of one first fixing portion 1111 is different from the widths of the other first fixing portions 1111. Among the multiple second fixing portions 172, the width of one second fixing portion 172 is different from the widths of the other second fixing portions 172. The first fixing portions 1111 and the second fixing portions 172 cooperate to position the relative positions of the stator 170 and the valve seat 116 in the circumferential direction, thereby preventing the stator 170 from being misaligned with the valve seat 116 during installation, which could result in sealing failure.

[0228] For example, Figure 6 As shown, there are three first fixing parts 1111, and they are all protrusions, such as Figure 9 As shown, there are three second fixing portions 172, all of which are raised. The circumferential width of one first fixing portion 1111 is greater than the circumferential widths of the other two first fixing portions 1111, and the circumferential width of one second fixing portion 172 is greater than the circumferential widths of the other two second fixing portions 172. The first fixing portion 1111 and the second fixing portion 172 cooperate to circumferentially position the stator 170 and the valve seat 116. This facilitates installation of the stator 170, avoids misalignment of the stator 170 resulting in a poor seal, and prevents water from leaking into the valve seat 116.

[0229] See also Figure 11 and Figure 12 As shown, according to some embodiments of the present invention, the movable plate 160 is provided with spaced-apart dynamic water inlet holes 161 and dynamic bypass holes 162. In the service position, the first and second water inlet chambers 130, 132 communicate with the tank inlet chamber 131 via the dynamic water inlet holes 161. The first and second water inlet chambers 130, 132, the dynamic water inlet holes 161, and the tank inlet chamber 131 define a service water path. At this point, raw water is delivered to the first and second water inlet chambers 130, 132 via the water inlet pipe 112. The raw water in the first and second water inlet chambers 130, 132 flows into the tank inlet chamber 131 through the dynamic water inlet holes 161. The raw water in the tank inlet chamber 131 is then delivered to the inlet of the resin tank 400 via the tank inlet pipe 114. The raw water contacts the resin, reducing the concentration of calcium and magnesium ions, forming soft water. The soft water flows from the outlet of the resin tank 400 into the tank outlet pipe 115 , and flows unidirectionally to the water outlet pipe 113 through the tank outlet pipe 115 , and is finally transported to the user end through the pipeline.

[0230] In the bypass position, the first water inlet chamber 130 and the second water inlet chamber 132 are connected to the bypass chamber 133 through the dynamic bypass hole 162. The first water inlet chamber 130, the second water inlet chamber 132, the dynamic bypass hole 162 and the bypass chamber 133 define a bypass waterway. Raw water is transported to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 and the second water inlet chamber 132 flows into the bypass chamber 133 through the dynamic bypass hole 162. The raw water in the bypass chamber 133 flows out through the water outlet pipe 113 and is transported to the user end through the pipeline. Figure 6 As shown, the tank inlet cavity 131 and the bypass cavity 133 are spaced apart along the circumferential direction of the valve seat 116, and the dynamic water inlet hole 161 and the dynamic bypass hole 162 are spaced apart in the circumferential direction of the movable plate 160. By rotating the movable plate 160, the dynamic water inlet hole 161 can be switched to be connected or disconnected with the tank inlet cavity 131, and the dynamic bypass hole 162 can be switched to be connected or disconnected with the bypass cavity 133.

[0231] See also Figure 11 As shown, according to some embodiments of the present invention, a water inlet channel 163 is provided on the surface of the rotor 160 facing away from the valve seat 116. The water inlet channel 163 connects the dynamic water inlet hole 161 with the first water inlet chamber 130, thereby directing water within the first water inlet chamber 130 into the dynamic water inlet hole 161. In some embodiments, a communication port 164 is further provided on the surface of the rotor 160 facing away from the valve seat 116. The communication port 164 connects the water inlet channel 163 with the first water inlet chamber 130. The communication port 164 is provided at the edge of the rotor 160 and extends radially along the rotor 160. Multiple communication ports 164 connect the water inlet channel 163 with the first water inlet chamber 130. The multiple communication ports 164 are spaced apart along the circumference of the rotor 160. Some of the communication ports 164 connect to the dynamic water inlet hole 161 or the dynamic bypass hole 162, allowing water within the first water inlet chamber 130 to flow into the dynamic water inlet hole 161 and the dynamic bypass hole 162 from multiple directions. The plurality of communication ports 164 can be evenly distributed along the circumferential direction of the movable plate 160 to evenly guide water into the dynamic water inlet hole 161 and the dynamic bypass hole 162. In this way, when the connecting plate 152 and the movable plate 160 are connected, the water in the first water inlet chamber 130 can flow to the dynamic water inlet hole 161 and the dynamic bypass hole 162 through the water inlet channel 163 and the communication port 164, and then flow to the tank inlet chamber 131 and the bypass chamber 133. When the water flows in the water inlet channel 163 and the communication port 164, the water exerts pressure on the movable plate 160, so that the movable plate 160 fits tightly against the valve seat 116, which is conducive to simplifying the fixing structure of the movable plate 160. Figure 11 As shown, the water inlet channel 163 can extend along an arc, that is, the water inlet channel 163 is arc-shaped, one end of the arc-shaped water inlet channel 163 is connected to the dynamic water inlet hole 161, and the other end is connected to the dynamic bypass hole 162.

[0232] like Figures 19-22 As shown, Figure 19 FIG. 1 is a structural diagram of the valve assembly 100 when the valve core 140 is located in the service position. Figure 20 Schematic diagram of the relative positions of the moving plate 160 and the stator 170 when the valve core 140 is located in the service position. Figure 21 FIG. 1 is a schematic diagram showing the relative positions of the moving plate 160 and the stator 170 from another perspective when the valve core 140 is located at the service position. Figure 22 This is a cross-sectional view of the water softener when the valve core 140 is located in the service position, and the arrows in the figure indicate the direction of water flow.

[0233] When the valve core 140 is in the service position, the first water inlet chamber 130, the second water inlet chamber 132, the connecting port 164, the water inlet channel 163, the dynamic water inlet hole 161, the fixed tank inlet hole 174 and the tank inlet chamber 131 jointly define a service water path. The dynamic water inlet hole 161 is connected to the tank inlet chamber 131 through the fixed tank inlet hole 174, the dynamic water inlet hole 161 is connected to the first water inlet chamber 130 through the water inlet channel 163 and the connecting port 164, and the dynamic bypass hole 162 is connected to the second water inlet chamber 132 through the fixed water inlet hole 173. Thus, the raw water is transported to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112, and the raw water in the first water inlet chamber 130 can flow into the water inlet channel 163 through the connecting port 164 (such as Figure 19 and Figure 20 The flow direction shown by the arrow 1) and then flows into the dynamic water inlet hole 161 (as shown in FIG. Figure 19 and Figure 20 The raw water in the second water inlet chamber 132 can flow into the water inlet channel 163 through the fixed water inlet hole 173 and the dynamic bypass hole 162, and then into the dynamic water inlet hole 161. After flowing into the dynamic water inlet hole 161, the raw water flows into the tank inlet chamber 131 through the fixed tank inlet hole 174. The raw water in the tank inlet chamber 131 is then transported to the inlet of the resin tank 400 through the tank inlet pipe 114.

[0234] 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 tube 410 is provided in the resin tank 400. One end of the central tube 410 is connected to the outlet of the resin tank 400, and the other end of the central tube 410 is connected to the resin tank 400. The resin is stored in the resin tank 400 and is located outside the central tube 410. Raw water enters the resin tank 400 from the inlet (as shown in FIG. Figure 22 The water flows in the direction indicated by arrow 2 and comes into contact with the resin. The resin absorbs 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 then flows through the tank outlet pipe 115 and the bypass check valve 137 to the water outlet pipe 113. The soft water output from the water outlet pipe 113 is delivered to the user through a pipeline.

[0235] like Figure 23 and Figure 24 As shown, Figure 24This is a cross-sectional view of the water softener with valve core 140 in the bypass position. The arrows in the figure indicate the direction of water flow. In the bypass position, the first water inlet chamber 130, the second water inlet chamber 132, the connecting port 164, the water inlet passage 163, the dynamic bypass hole 162, the fixed bypass hole 171, and the bypass chamber 133 collectively define a bypass waterway. The dynamic bypass hole 162 communicates with the bypass chamber 133 via the fixed bypass hole 171. The dynamic bypass hole 162 communicates with the first water inlet chamber 130 via the water inlet passage 163 and the connecting port 164. The dynamic water inlet hole 161 communicates with the second water inlet chamber 132 via the fixed water inlet hole 173. The raw water is transported to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 flows into the dynamic bypass hole 162 through the connecting port 164 and the water inlet channel 163. The raw water in the second water inlet chamber 132 flows into the dynamic bypass hole 162 through the fixed water inlet hole 173, the dynamic water inlet hole 161 and the water inlet channel 163. The raw water flowing into the dynamic bypass hole 162 flows into the bypass chamber 133 through the fixed bypass hole 171. The raw water in the bypass chamber 133 flows out from the water outlet pipe 113 and is transported to the user end through the pipeline. Figure 24 As shown, in this process, the raw water does not pass through the resin tank 400. In this way, water can be flexibly supplied according to user needs during use, and the consumption of resin is reduced.

[0236] See also Figure 6 As shown, according to some embodiments of the present invention, the valve seat 116 is provided with a salt absorption chamber 134 and a salt absorption communication chamber 135 separated from each other, and the salt absorption chamber 134 is suitable for communicating with the salt box 500. Figure 12 As shown, the rotor 160 is provided with a dynamic salt absorption water diversion hole 165, which is a blind hole 168 and is located on the surface of the rotor 160 facing the valve seat 116. The salt absorption communication cavity 135 is adapted to communicate with the dynamic salt absorption water diversion hole 165. The dynamic water inlet hole 161 extends through the rotor 160 along the thickness direction of the rotor 160, and the dynamic salt absorption water diversion hole 165 is separated from the dynamic water inlet hole 161. In the salt absorption position, the dynamic water inlet hole 161 is connected to the dynamic salt absorption water diversion hole 165 through the salt absorption connecting chamber 135. The dynamic salt absorption water diversion hole 165 is connected to the salt absorption chamber 134 and the bypass chamber 133 respectively. The dynamic water inlet hole 161, the salt absorption connecting chamber 135, the dynamic salt absorption water diversion hole 165 and the salt absorption chamber 134 define a salt absorption path, and the dynamic water inlet hole 161, the salt absorption connecting chamber 135, the dynamic salt absorption water diversion hole 165 and the bypass chamber 133 define a bypass water path. In this way, in the salt absorption position, raw water can be provided to users through the bypass water path.

[0237] like Figure 6 and Figure 12As shown, the salt absorption communication cavity 135 extends in the radial direction of the valve seat 116, with one end of the salt absorption communication cavity 135 located at the center of the valve seat 116; the dynamic salt absorption water diversion hole 165 extends in the radial direction of the rotor 160, with one end of the dynamic salt absorption water diversion hole 165 located at the center of the rotor 160. In this way, during the rotation of the rotor 160, one end of the salt absorption communication cavity 135 remains in communication with one end of the dynamic salt absorption water diversion hole 165. The salt absorption communication cavity 135 and the dynamic salt absorption water diversion hole 165 can function to connect the through hole in the rotor 160 with the chamber in the valve seat 116.

The arrows in the figure indicate the direction of water flow.

[0239] At the salt absorption position, the dynamic water inlet hole 161 communicates with the salt absorption communication chamber 135 through the fixed salt absorption communication hole 176 on the stator 170. The salt absorption communication chamber 135 communicates with the dynamic salt absorption water diversion hole 165 through the fixed salt absorption communication hole 176. The dynamic salt absorption water diversion hole 165 communicates with the bypass chamber 133 through the fixed bypass hole 171. The dynamic salt absorption water diversion hole 165 communicates with the salt absorption chamber 134 through the fixed salt absorption hole 175. The dynamic bypass hole 162 communicates with the second water inlet chamber 132 through the dynamic and fixed water inlet hole 173.

[0240] Raw water is fed into the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 flows to the dynamic water inlet hole 161 through the connecting port 164 and the water inlet channel 163. The raw water in the second water inlet chamber 132 flows into the dynamic water inlet hole 161 through the fixed water inlet hole 173, the dynamic bypass hole 162 and the water inlet channel 163. The raw water in the dynamic water inlet hole 161 flows into the salt absorption connecting chamber 135 (such as the fixed salt absorption connecting hole 176) through the fixed salt absorption connecting hole 176. Figure 27 and Figure 28 The raw water in the salt absorption connecting cavity 135 flows into the dynamic salt absorption water diversion hole 165. In the dynamic salt absorption water diversion hole 165, a portion of the raw water flows into the salt absorption cavity 134 through the fixed salt absorption hole 175 (as shown in FIG. Figure 28another part of the raw water flows into the bypass chamber 133 through the fixed bypass hole 171, and the raw water in the bypass chamber 133 is output through the water outlet pipe 113 to be provided to the user.

[0241] According to some embodiments of the present invention, the salt absorption chamber 134 is selectively connected to the salt box 500. When in the salt absorption position: the salt absorption chamber 134 is connected to the salt box 500, the valve assembly 100 is in the salt absorption mode, and the salt water in the salt box 500 and the raw water in the salt absorption chamber 134 are transported to the resin tank 400 to clean and restore the resin so that the resin recovers its adsorption capacity; the salt absorption chamber 134 is disconnected from the salt box 500, and the valve assembly 100 is in the slow washing mode. At this time, the salt box 500 stops providing salt water, and the raw water in the salt absorption chamber 134 is transported to the resin tank 400 to flush the resin tank 400 to flush the salt in the resin. Figure 7 As shown, in some embodiments, the valve assembly 100 further includes a jet tube 181, in which an ejector 240 is disposed. The jet tube 181 is connected to the valve body 110 and is in communication with the salt absorption chamber 134. The jet tube 181 is in communication with both the salt tank 500 and the resin tank 400. When the salt absorption chamber 134 is in communication with the salt tank 500, the ejector 240 can transport water in the salt absorption chamber 134 and brine in the salt tank 500 to the resin tank 400. When the salt absorption chamber 134 is disconnected from the salt tank 500, the jet tube 181 can transport water in the salt absorption chamber 134 to the resin tank 400 to flush the resin.

[0242] See also Figure 29 As shown, according to some embodiments of the present invention, the valve assembly 100 further includes a sewage drain line 2107, and the sewage drain line 2107 is selectively connected to the tank inlet pipe 114, and the tank inlet pipe 114 is connected to the inlet of the resin tank 400, so that the sewage drain line 2107 is connected to the resin tank 400 through the tank inlet pipe 114. When in the salt absorption position, the sewage drain line 2107 is connected to the tank inlet pipe 114. The sewage generated by cleaning the resin in the salt absorption mode and the slow washing mode can be discharged through the sewage drain line 2107. In some embodiments, the adapter assembly 200 has a sewage control assembly 250, and the sewage control assembly 250 is used to control the on-off of the sewage drain line 2107 and the tank inlet pipe 114. In a specific example, as Figure 29 As shown, the sewage control assembly 250 is located at the connection point between the sewage discharge path 2107 and the tank inlet pipe 114, and a driving block 1433 is provided on the bottom surface of the driven gear 1431. When the valve core 140 is in the salt absorption position, the driving block 1433 pushes the pressure rod to move, so that the sewage discharge path 2107 is connected to the tank inlet pipe 114.

[0243] 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 salt absorption mode, the pressure rod is in the open state. A portion of the raw water input to the valve assembly 100 is transported to the jet pipe 181 (as shown in FIG. Figure 29 The jet tube 181 mixes the salt water and the raw water and delivers them to the outlet of the resin tank 400. The mixed salt water flows through the central tube 410 to the other end of the resin tank 400 and contacts the resin, thereby replacing the calcium and magnesium ions adsorbed on the resin and restoring the adsorption capacity of the resin. The mixed salt water after cleaning the resin flows out from the inlet of the resin tank 400 and is discharged from the sewage channel 2107. The other part of the raw water input to the valve assembly 100 is delivered to the outlet pipe 113 (as shown in FIG. 1 ) through the bypass water channel. Figure 29 The flow direction shown by arrow 3 in the figure is provided to the user. Figure 30 As shown, in slow-wash mode, the raw water flows in the same direction as in the aforementioned brine absorption mode, except that brine is not provided by brine tank 500, which will not be further described here. In the brine absorption position, valve assembly 100 provides water through the brine absorption line and the bypass water line. This allows water to be provided to the user simultaneously while the resin is being cleaned and reduced, ensuring uninterrupted water supply and preventing any disruption to user water use.

[0244] like Figure 6 and Figure 12 As shown, according to some embodiments of the present invention, the movable plate 160 is provided with a dynamic backwash hole 166 that passes through along its thickness direction, the seat body is provided with a backwash chamber 136, and the valve body 110 is provided with a backwash pipe 182, which is connected to the backwash chamber 136 and the backwash pipe 182 is connected to the central pipe 410 of the resin tank 400. Figure 6 In the example, the backwash chamber 136 and the salt absorption chamber 134 are spaced apart in the radial direction of the valve seat 116. Figure 12 In the example, the dynamic water inlet hole 161 , the dynamic backwash hole 166 and the dynamic bypass hole 162 are sequentially spaced apart in the circumferential direction of the dynamic plate 160 .

[0245] In the backwash position, backwash chamber 136 communicates with dynamic bypass hole 162 to define a backwash water path; dynamic backwash hole 166 communicates with bypass chamber 133 to define a bypass water path. In the backwash position, a portion of the raw water entering valve assembly 100 is transported through the backwash water path and backwash pipe 182 to the resin tank 400 to backwash the resin, flush out broken resin, and increase the spacing between resin particles. This ensures that the resin particles are fully exposed to the raw water in the service position, enhancing the adsorption of calcium and magnesium ions in the raw water. The remaining portion of the raw water entering valve assembly 100 is discharged through the bypass water path and outlet pipe 113 to be provided to the user, ensuring uninterrupted water supply. When valve core 140 is in the backwash position, wastewater discharge path 2107 communicates with the resin tank 400 to discharge wastewater generated during the backwash process.

[0246] like Figures 31 to 34 As shown, the valve core 140 is in the backwash position at this time, and the arrows in the figure indicate the direction of water flow. Figure 31 Schematic diagram of the structure of the valve assembly 100; Figure 32 is a schematic diagram of the relative positions of the moving plate 160 and the stator 170; Figure 33 Schematic diagram of the relative positions of the moving plate 160 and the stator 170 from another perspective; Figure 34 A cross-sectional view of a water softener.

[0247] In the backwash position, the valve core 140 and the valve seat 116 define a backwash water path and a bypass water path. The dynamic bypass hole 162 is connected to the backwash chamber 136 through the fixed backwash hole 177, the dynamic backwash hole 166 is connected to the bypass chamber 133 through the fixed bypass hole 171, and the dynamic water inlet hole 161 is connected to the second water inlet chamber 132 through the fixed water inlet hole 173. Raw water is transported to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112 (as shown in FIG. Figure 34 The raw water in the first water inlet chamber 130 flows into the dynamic bypass hole 162 and the dynamic backwash hole 166 through the communication port 164 and the water inlet channel 163. The raw water in the second water inlet chamber 132 flows into the dynamic bypass hole 162 and the dynamic backwash hole 166 through the fixed water inlet hole 173, the dynamic water inlet hole 161, and the water inlet channel 163.

[0248] The raw water flowing to the dynamic bypass hole 162 flows into the backwash chamber 136 through the fixed backwash hole 177 (as shown in FIG. Figure 34The raw water flows in the direction of the flow indicated by the arrow 2 in the middle), thereby flowing into the central tube 410 of the resin tank 400 through the backwash pipe 182. The raw water is transported to the other end of the resin tank 400 through the central tube 410 to flush the resin. At the backwash position, the sewage discharge path 2107 is connected to the resin tank inlet pipe 114 of the resin tank 400. The sewage generated after the raw water flushes the resin flows out through the inlet of the resin tank 400 and is discharged from the sewage discharge path 2107. In some embodiments, a plurality of push blocks are provided on the driven gear 1431. When the valve core 140 moves to the backwash position, one of the push blocks pushes the pressure rod, so that the sewage discharge path 2107 is connected to the tank inlet pipe 114. The raw water flowing to the dynamic backwash hole 166 flows into the bypass chamber 133 through the fixed bypass hole 171 (as shown in FIG. Figure 34 The water is then output from the outlet pipe 113 to provide to the user. Thus, during the backwash process, the water softener can supply water uninterruptedly.

[0249] According to some embodiments of the present invention, a water supply chamber separated from the salt absorption chamber 134 is provided on the valve seat 116. The valve assembly 100 further includes a water supply pipe connected to the valve body 110, and the water supply chamber is connected to the water supply pipe. A salt absorption check valve 260 is provided between the water supply pipe and the jet pipe 181. The salt absorption check valve 260 is unidirectional based on the pressure difference between the water supply pipe and the jet pipe 181 to control the connection and disconnection of the jet pipe 181 and the resin tank 400. For example, Figure 29 In the example, when the valve core 140 is in the salt absorption position, the raw water flows into the jet tube 181 through the salt water absorption line, and no water flows through the water supply pipe. At this time, the pressure in the jet tube 181 is greater than the pressure in the water supply pipe, and the jet tube 181 is connected to the resin tank 400, and the raw water can flow from the jet tube 181 to the resin tank 400.

[0250] In the water replenishment position, the dynamic water inlet 161 is connected to both the water replenishment chamber and the salt absorption chamber 134. The pressure differential between the water replenishment pipe and the jet pipe 181 is zero. The salt absorption 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 salt tank 500. The salt absorption chamber 134 replenishes water into the salt tank 500 through the jet pipe 181. The dynamic water inlet 161, the water replenishment chamber, the salt absorption chamber 134, and the jet pipe 181 define a water replenishment waterway. It is understood that the salt tank 500 typically contains salt, and it is necessary to maintain a "salt-only" state within the salt tank 500 to prevent the salt tank 500 from failing to provide salt water during use, resulting in resin reduction failure. In the water replenishment position, water is replenished to the salt tank 500 through the water replenishment waterway to dissolve the salt within the salt tank 500 and replenish the salt water.

[0251] 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 working process of the valve assembly 100 in the water supply position are described below using the example that 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.

[0252] like Figures 35-38 As shown, at this time, the valve core 140 is located in the water replenishment position, and the arrows in the figure indicate the direction of water flow. Figure 35 Schematic diagram of the structure of the valve assembly 100; Figure 36 is a schematic diagram of the relative positions of the moving plate 160 and the stator 170; Figure 37 This is another perspective diagram showing the relative positions of the moving plate 160 and the fixed plate 170. In the water replenishment position, the dynamic water inlet 161 communicates with the salt absorption chamber 134 via the fixed salt absorption hole 175. Furthermore, the dynamic water inlet 161 communicates with the backwash chamber 136 via the fixed backwash hole 177. The dynamic backwash hole 166 communicates with the tank inlet chamber 131 via the fixed tank inlet hole 174. The first water inlet chamber 130, the dynamic water inlet 161, the water replenishment chamber, the salt absorption chamber 134, and the jet tube 181 define a water replenishment waterway. The first water inlet chamber 130, the dynamic backwash hole 166, and the tank inlet chamber 131 collectively define a service waterway.

[0253] Raw water is delivered to the first and second water inlet chambers 130 and 132 via the water inlet pipe 112. The raw water in the first water inlet chamber 130 flows through the connecting port 164 and the water inlet channel 163 to the dynamic water inlet hole 161 and the dynamic backwash hole 166. A portion of the raw water in the dynamic water inlet hole 161 flows into the backwash chamber 136 through the fixed backwash hole 177 and then into the backwash pipe 182. Another portion of the raw water in the dynamic water inlet hole 161 flows into the salt absorption chamber 134 through the fixed salt absorption hole 175 and then into the jet pipe 181. This balances the pressure exerted by the water in the backwash pipe 182 on the salt absorption check valve 260 with the pressure exerted by the water in the jet pipe 181 on the salt absorption check valve 260. The salt absorption check valve 260 blocks the connection between the jet pipe 181 and the resin tank 400, while maintaining communication between the jet pipe 181 and the salt tank 500. Thus, the water in the salt absorption chamber 134 is transported to the salt tank 500 through the jet pipe 181 to replenish the salt water. The raw water in the dynamic backwash hole 166 flows into the tank chamber 131 through the fixed tank hole 174 and is then transported to the user end through the water outlet pipe 113.

[0254] According to some embodiments of the present invention, a mixed water zone is provided between the service position and the salt absorption position. When the valve core 140 rotates to the mixed water zone, the valve core 140 and the valve seat 116 jointly define a service waterway and a bypass waterway. Figure 6As shown, the tank inlet chamber 131, the salt absorption chamber 134 and the bypass chamber 133 are arranged in sequence in the circumferential direction of the valve seat 116, and the service position and the salt absorption position are adjacent, as shown in FIG. Figure 20 and Figure 27 As shown, the valve core 140 can be switched to the salt absorption position by rotating a certain angle in the counterclockwise direction from the service position. Figure 40 As shown, within the mixed water range, dynamic water inlet hole 161 communicates with tank inlet chamber 131, and further communicates with dynamic salt absorption water diversion hole 165 via salt absorption connecting chamber 135. Dynamic salt absorption water diversion hole 165 communicates with bypass chamber 133. Dynamic water inlet hole 161 and tank inlet chamber 131 collectively define a service waterway, while dynamic water inlet hole 161, salt absorption connecting chamber 135, dynamic salt absorption water diversion hole 165, and bypass chamber 133 collectively define a bypass waterway. A portion of raw water entering valve assembly 100 is delivered to resin tank 400 via the service waterway to displace calcium and magnesium ions in the raw water, producing soft water. The soft water is then delivered to outlet pipe 113 via outlet pipe 115. Another portion of raw water is delivered to outlet pipe 113 via the bypass waterway. Thus, within the mixed water range, the water output from outlet pipe 113 is a mixture of soft water and raw water. In the mixed water zone, the valve core 140 is adjusted to adjust the opening of the service water channel and the bypass water channel to adjust the amount of soft water and the amount of raw water in the outlet pipe 113, thereby achieving the purpose of adjusting the hardness of the water.

[0255] like Figures 39 to 42 As shown, the valve core 140 is located in the mixed water zone. Figure 39 Schematic diagram of the structure of the valve assembly 100, where the arrows in the figure indicate the direction of water flow; Figure 40 Schematic diagram of the relative positions of the moving plate 160 and the stator 170, wherein the arrows in the figure indicate the direction of water flow; Figure 41 Schematic diagram of the relative positions of the moving plate 160 and the stator 170 from another perspective; Figure 42 A cross-sectional view of a water softener.

[0256] In the mixed water zone, the dynamic water inlet hole 161 communicates with the tank inlet chamber 131 via the fixed tank inlet hole 174. Furthermore, the dynamic water inlet hole 161 communicates with the salt absorption connecting chamber 135 via the fixed salt absorption connecting hole 176. The salt absorption connecting chamber 135 communicates with the dynamic salt absorption water diversion hole 165, which in turn communicates with the bypass chamber 133 via the fixed bypass hole 171. The dynamic bypass hole 162 communicates with the second water inlet chamber 132 via the fixed water inlet hole 173. At this time, raw water is input into the first and second water inlet chambers 130, 132, through the water inlet pipe 112. Raw water in the first water inlet chamber 130 flows to the dynamic water inlet hole 161 through the connecting port 164 and the water inlet channel 163. Raw water in the second water inlet chamber 132 flows to the dynamic water inlet hole 161 through the fixed water inlet hole 173, the dynamic bypass hole 162, and the water inlet channel 163.

[0257] A portion of the raw water in the water inlet hole flows into the tank cavity 131 through the fixed tank hole 174 (such as Figure 40 and Figure 41 The raw water in the tank inlet cavity 131 is transported to the inlet of the resin tank 400 through the tank inlet pipe 114 (as shown in the flow direction of the arrow 1). Figure 42 The raw water enters the resin tank 400 and contacts the resin to displace the calcium and magnesium ions in the raw water, forming soft water. The soft water is output through the central pipe 410 and the outlet of the resin tank 400, and is transported to the water outlet pipe 113 (as shown in the flow direction of the arrow 1). Figure 42 The flow direction is shown by the arrow 1'.

[0258] Another part of the raw water in the water inlet hole flows into the dynamic salt absorption water hole 165 through the fixed salt absorption connecting hole 176 and the salt absorption connecting cavity 135, and then flows into the bypass cavity 133 (such as Figure 40 and Figure 41 The raw water in the bypass chamber 133 flows into the outlet pipe 113 (as shown by the arrow 2). Figure 42 The flow direction shown by the arrow 2 in the middle) is such that the water in the outlet pipe 113 is a mixture of soft water and raw water. Figure 41 As shown. The rotation angle of the valve core 140 can be adjusted to adjust

[0259] like Figure 9 As shown, the angle between the fixed salt absorption hole 175 and the fixed bypass cavity 133 is the water mixing angle. Figure 9 In the example shown, the mixing angle is 35 degrees. Of course, the mixing angle can also be other angles. Figure 20 As shown, when the valve core 140 rotates from the service position to the salt absorption position in the direction of the arrow, when the rotation angle is less than the water mixing angle, the dynamic salt absorption water diversion hole 165 is connected to the bypass chamber 133, and the dynamic salt absorption water diversion hole 165 is not connected to the salt absorption chamber 134.

[0260] like Figure 13-15As shown, according to some embodiments of the present invention, the adapter assembly 200 further includes an adapter integrated seat 210, the internal structure of the adapter integrated seat 210 is composed of a first flow path 2101, a second flow path 2102, a mixed salt flow path 2103, a backwash flow path 2104 and a transfer chamber 2105, and the outer peripheral side of the adapter integrated seat 210 corresponding to each flow path is provided with an adapter interface; one end of the first flow path 2101 is connected to the tank inlet pipe 114 through the corresponding adapter interface, and the other end of the first flow path 2101 is connected to the tank inlet pipe 114 through the 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 tank outlet pipe 115 through the corresponding adapter, one end of the mixed salt flow path 2103 is connected to the jet tube 181, and one end of the backwash flow path 2104 is connected to the backwash pipe 182, and 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 center tube 410 of the resin tank 400 through the adapter cavity 2105. The second flow path 2102, the salt mixing 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 with the central tube 410 of the resin tube, so that the water path enters the central tube 410 through the transfer chamber 2105 when in the salt absorption position (slow washing position), backwash position and water replenishment position, forming a reverse circulation water path in the resin tank 400.

[0261] like Figure 1 and Figure 16 As shown, in the specific configuration, the adapter assembly 200 and the resin tank 400 are connected through the water channel component 300, that is, the water channel is guided into the resin tank 400 by the water channel component 300. In this embodiment, the first flow path 2101, the second flow path 2102, the salt mixing flow path 2103, and the backwash flow path 2104 are all flow channel structures constructed in the adapter integrated seat 210. Their respective flow paths are formed with respective ports on the outer peripheral end surface of the adapter integrated seat 210, and each port has a transfer interface, which is used to achieve communication with the valve assembly 100 and the water channel component 300. Among them, the two ends of the first flow path 2101 are connected to the tank inlet pipe 114 and the water channel component 300 respectively through the corresponding transfer interfaces provided on the outer surface of the adapter integrated seat 210, so that raw water can be introduced from the water inlet pipe 112 of the valve assembly 100 into the resin tank 400 filling part of the resin tank 400.

[0262] like Figure 13 、 Figure 15As shown, the transfer chamber 2105 is a chamber constructed inside the transfer integrated seat 210, and 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, which 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 to the central pipe 410 in the resin tank 400 through the transfer chamber 2105, realizing the flow of the reverse circulation water path. During the specific setting, 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 adapter interfaces, 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 chamber 2105. The adapter chamber 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 the service position, and finally realize soft water supply through the outlet pipe 113.

[0263] Among them, one end of the mixed salt flow path 2103 is connected to the valve cavity 111 of the valve assembly 100 through the jet tube 181. The movable plate 160 and the fixed plate 170 in the valve cavity 111 can realize water path switching, so that the raw water can enter the mixed salt flow path 2103, and can be mixed with the brine in the mixed salt flow path 2103 and enter the central tube 410 of the resin tank 400. The brine entering the central tube 410 can clean the resin particles and realize the regeneration of the resin particles.

[0264] One end of the backwash flow path 2104 is connected to the valve cavity 111 of the valve assembly 100 through the backwash pipe 182. The movable plate 160 and the fixed plate 170 in the valve cavity 111 can realize water path switching, so that raw water can enter the backwash flow path 2104. The backwash flow path 2104 is connected to the central tube 410 of the resin tank 400 through the adapter chamber 2105, so that raw water can enter from the central tube 410 to backwash the resin particles and realize the regeneration of the resin particles.

[0265] It can be understood that the construction of the adapter chamber 2105 enables multiple flow paths to be connected to the central tube 410 of the resin tank 400 through one port of the adapter chamber 2105, reducing the number of ports for 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.

[0266] When setting specific settings, such as Figure 13As shown, one end of the first flow path 2101, the second flow path 2102, the salt mixing flow path 2103, and the backwash flow path 2104 extend in the same direction, wherein the first flow path 2101 and the second flow path 2102 are arranged side by side, and the salt mixing flow path 2103 and the backwash flow path 2104 are arranged side by side. It will be understood that the one ends of the first flow path 2101, the second flow path 2102, the salt mixing flow path 2103, and the backwash flow path 2104 extend in the same direction, so that the valve assembly 100 and the adapter assembly 200 can achieve multiple flow paths through a single alignment, simplifying the flow path connection with the valve assembly 100 and facilitating assembly and disassembly. Furthermore, the first flow path 2101 and the second flow path 2102 are arranged side by side, and the salt mixing flow path 2103 and the backwash flow path 2104 are arranged side by side. By grouping and arranging flow paths with approximately the same flow rate side by side, the symmetry of the flow paths of the adapter assembly 200 is improved, thereby improving the operational stability of the adapter assembly 200.

[0267] like Figure 13 and Figure 29 As shown, according to some embodiments of the present invention, the adapter assembly 210 further includes a brine flow path 2106. One end of the brine flow path 2106 is connected to the brine tank 500, and the other end of the brine flow path 2106 is connected to the brine mixing flow path 2103. The brine flow path 2106 and the brine mixing flow path 2103 are connected at the front end of the adapter chamber 2105. It can be understood that the brine flow path 2106 is used to provide brine of a certain concentration to the brine mixing flow path 2103, which is then mixed with the raw water in the brine mixing flow path 2103 to provide the required brine concentration for resin regeneration. When brine is needed for resin regeneration, the brine flow path 2106 can effectively introduce the brine into the brine mixing flow path 2103, ensuring sufficient mixing and uniform distribution of the brine. By connecting the brine flow path 2106 and the brine mixing flow path 2103, the brine supply path is simplified, improving operational convenience and device efficiency.

[0268] like Figure 14 As shown, according to some embodiments of the present invention, adapter assembly 200 further includes an ejector 240, which is positioned at the junction of salt absorption flow path 2106 and salt mixing flow path 2103, so that ejector 240 can draw salt water into salt mixing flow path 2103. It will be appreciated that by positioning ejector 240 in both the salt absorption flow path and salt mixing flow path 2103, as raw water passes through salt mixing flow path 2103, it provides salt absorption power to salt absorption flow path 2106, thereby reducing the need for separate salt absorption power for salt absorption flow path 2106 and simplifying the overall structure of the water softening device. Furthermore, ejector 240 can mix the salt water in salt absorption flow path 2106 and salt mixing flow path 2103 with the raw water, thereby improving the uniformity and efficiency of salt water mixing, thereby ensuring sufficient resin regeneration and enhancing the overall treatment effect.

[0269] According to some embodiments of the present invention, a wastewater discharge path 2107 is disposed within the adapter assembly 210 and communicates with the resin filling portion 420 of the resin tank 400 via the first flow path 2101. It is understood that the wastewater discharge path 2107 communicates with the first flow path 2101 to flow to the resin filling portion 420 of the resin tank 400. Since the resin particles in this embodiment are treated in a backwash mode, i.e., a reverse circulation waterway is used to process the resin particles, when cleaning or replacing the resin, the wastewater after the resin cleaning or replacement is discharged from the end of the resin tank 400 where the raw water enters the resin during normal softening. By connecting the wastewater discharge path 2107 to the first flow channel 310, the need for a separate wastewater outlet on the resin tank 400 is reduced, simplifying the overall structure and flow path arrangement of the softening device and facilitating assembly between the valve assembly 100 and the resin tank 400 or the waterway component 300 is eliminated.

[0270] When setting specific settings, such as Figure 3 and Figure 14 As shown, the sewage control assembly 250 includes a sewage pressure rod 251, which has an axially arranged extrusion end 2511 and a mating sealing end 2512. The extrusion end 2511 is located in the driven gear 1431 and can cooperate with the drive block 1433 to be pressurized. The mating sealing end 2512 is located in the sewage water path 2107. The extrusion end 2511 is suitable for causing the mating sealing end 2512 to move to open the sewage water path 2107 after being squeezed. In the normal state, the sewage discharge channel 2107 is in a closed state. Only when sewage discharge is required, the sewage discharge channel 2107 will be opened for sewage discharge operation. In this embodiment, in the normal state, the driving block 1433 is not in contact with the extrusion end 2511. When sewage discharge is required, the driven gear 1431 rotates, and the driving block 1433 is abutted against the extrusion end 2511 of the sewage pressure rod 251. When abutting, it can generate thrust on its own center rod body, so that the center rod body moves. After the center rod body moves, the sealing end 2512 can be separated from the sewage discharge channel 2107, so that the sewage discharge channel 2107 is opened. The whole process is controlled by mechanical transmission, which will not be affected by factors such as electromagnetic interference, thereby improving the reliability of the device.

[0271] It is understandable that the sewage pressure rod 251 is disposed in the sewage discharge channel 2107. Under normal circumstances, the sewage pressure rod 251 can close the sewage discharge channel. Only when the sewage discharge channel 2107 needs to be opened will the driving block 1433 be opened to realize the opening of the sewage discharge channel 2107. In this embodiment, the sewage pressure rod 251 can be a conventional sewage pressure rod 251. The conventional sewage pressure rod 251 includes a rod body, and one end of the rod body has a sealing head, that is, the above-mentioned matching sealing end 2512. When it is not necessary to open, the sealing head can achieve the blocking of the sewage discharge channel 2107. When it is necessary to open, the sewage discharge channel 2107 is opened through the action of an external force. As for the specific sewage pressure rod 251, those skilled in the art should be aware of its specific structure, so it will not be further described.

[0272] For example, in a specific application, the position of the driven gear 1431 with the driving block 1433 is configured as a salt absorption position and controlled by a control system. That is, when the control system sends a signal that salt absorption is required, the driven gear 1431 can be rotated, and the driving block 1433 is abutted against the extrusion end 2511 of the sewage pressure rod 251 by rotation, thereby opening the sewage discharge path 2107. When the sewage discharge path 2107 does not need to be opened, the driven gear 1431 is controlled to rotate so that the driving block 1433 is misaligned with the extrusion end 2511 of the sewage pressure rod 251, and the sewage pressure rod 251 can close the sewage discharge path 2107 again.

[0273] It is understood that in this embodiment, the opening of the sewage discharge channel 2107 is achieved by providing a driving block 1433 on the driven gear 1431. The overall structure is simple and efficient, and can quickly respond to achieve rapid opening of the sewage discharge channel 2107. In addition, the opening of the sewage discharge channel 2107 is achieved through mechanical transmission, which has higher reliability and anti-interference ability.

[0274] like Figure 3 As shown, in a specific configuration, there can be multiple drive blocks 1433, which are arranged at intervals. In an overall product, sewage discharge is often required in multiple states. In this embodiment, by providing multiple drive blocks 1433 on the driven gear 1431, sewage discharge can be performed in different states, thereby improving the applicability of the sewage discharge system in this example.

[0275] 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. By distributing the two drive blocks 1433 at different positions, the two drive blocks 1433 can respectively control the opening of the sewage discharge channel in at least two states. Of course, the number of drive blocks 1433 can also be three, four, etc., and the drive blocks 1433 are usually distributed in different positions to enable them to correspond to different states. The drawings in the specification of this application only illustrate the method of two drive blocks 1433.

[0276] In specific 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 distances between the multiple drive blocks 1433 and the extrusion end 2511 of the sewage pressure rod 251 are roughly the same. In theory, the minimum distances between the multiple drive blocks 1433 and the pressure rod assembly are equal, but due to processing and assembly, there are often certain errors, so the minimum distances can be roughly the same. It is understandable that this minimum distance can reflect the depth of the action of the sewage pressure rod 251. Generally speaking, the sewage pressure rod 251 has a fixed action depth to achieve complete sealing of the sewage discharge channel 2107. By limiting the equal minimum distance, the sewage discharge channel 2107 can be stably opened when opened, and can ensure that it is opened to a fully open state, thereby improving its opening stability.

[0277] According to an embodiment provided by the present invention, Figure 3 As shown, a lever mechanism 270 is provided between the drive block 1433 and the drain lever 251. Lever mechanism 270 is used to amplify and transmit thrust. Drive block 1433 is mounted on a driven gear 1431, which is connected to the rotating shaft 150 to transmit mechanical energy, causing the movable plate 160 to rotate and switch the waterway. In this embodiment, the provision of lever mechanism 270 increases the service life of the drain lever 251 and reduces the difficulty and cost of maintenance.

[0278] It is understandable that the driven gear 1431 meshes with the driving gear 1432 and is connected to the rotating shaft 150. The direct interaction of the driving block 1433 with the sewage pressure rod 251 makes the driving block 1433 susceptible to damage. This problem is particularly prominent in cases where the driving block 1433 is used for a long time. Once the driving block 1433 is damaged, the driven gear 1431 needs to be disassembled, which is difficult to disassemble and can easily cause damage to the valve core 140 during the disassembly and assembly process. In this embodiment, by providing a lever mechanism 270 between the driving block 1433 and the sewage pressure rod 251, the transmission is carried out through the intermediate lever mechanism 270, which greatly avoids damage to the driving block 1433 and extends the service life of the driving block 1433. Compared with the disassembly and maintenance of the driven gear 1431, the disassembly of the lever mechanism 270 is simpler, and the maintenance difficulty and cost are lower.

[0279] like Figure 14 and Figure 29 As shown, according to one embodiment provided by the present invention, the adapter assembly 200 further includes a salt absorption check valve 260, which is disposed within the adapter chamber 2105 and at the end of the mixed salt flow path 2103. It is understood that the salt absorption check valve 260 can be a one-way valve, a check valve, or a similar component. Its operating principle prevents backflow, thereby improving the reliability and stability of the water softening device and reducing the possibility of maintenance and failure. Furthermore, the use of the salt absorption check valve 260 can ensure the accuracy and continuity of the brine supply, meet the requirements of resin regeneration, and improve the overall treatment effect.

[0280] In a specific configuration, a first adapter 220 and a second adapter 230 are provided at the bottom end of the adapter integration base 210. The first adapter 220 communicates with the first flow path 2101, thereby connecting the first flow path 2101 to the resin filling portion 420 in the resin tank 400. The second adapter 230 communicates with the adapter cavity 2105, thereby connecting each flow path to the central tube 410 in the resin tank 400. It can be understood that the coordinated use of the first adapter 220 and the second adapter 230 facilitates the connection between the adapter cavity 2105 and the central tube 410, and between the first flow path 310 and the resin tank 400, thereby improving the flexibility and maintainability of the device.

[0281] like Figure 16-Figure 18As shown, according to an embodiment provided by the present invention, the water channel component 300 includes a main body 301, the main body 301 is connected to the resin tank 400, the main body 301 includes a first flow channel 310 and a second flow channel 320, and 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 transfer cavity 2105 is connected to the central tube 410 in the resin tank 400 through the two connection ends. The first flow channel 310 is provided with 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 communicated with each other, wherein the first connection end 330 is used for fluid input or fluid output; the second flow channel 320 is provided with 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 tube, and the two are communicated with each other, wherein the second connection end 340 is used for fluid input or fluid output. In the design of the water channel component, it is necessary to meet the switching of the five functional channels of water supply, backwash, regeneration, water replenishment and forward washing in the water softener. Therefore, the water channel component usually integrates multiple flow channels into an integrated structure, which undoubtedly requires a complex molding mold to construct multiple flow channels. In this embodiment, through two flow channels, namely the first flow channel 310 and the second flow channel 320, the two flow channel pipes are respectively provided with a connecting port 164, namely the first connecting port 350 and the second connecting port 360. Figure 18 The two connection ports enable two flow channels to be connected to the resin filling portion 420 and the central tube 410 in the resin tank 400, respectively. The central tube 410 in the resin tank 400 and the resin filling portion 420 surrounding the central tube 410 are separated by their respective tube walls. This allows the two connection ports to be connected to different parts of the resin tank 400, thereby enabling the flow direction in the resin tank 400 to be switched.

[0282] In this embodiment, the first flow channel 310 and the second flow channel 320 are respectively used for the input or output of liquid fluids, and the input or output is controlled and selected by the valve assembly 100 connected thereto. It is understood that the valve assembly 100 needs to meet the requirements of the softening water path during the water softening process and the regeneration path for the resin particles in the resin barrel. 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 tube 410 and is output from the second connection port 360 through the second flow channel 320. 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 connecting 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 portion of the resin tank 400 to clean the resin particles, and then enters the first flow channel 310 and is output from the first connecting port 350 in the first flow channel 310. At this time, the first connecting port 350 is used for fluid output, and the second connecting port 360 is used for fluid input.

[0283] It can be understood that in this embodiment, the switching between the soft water channel and the regeneration water channel is achieved through two flow channels, which simplifies the structure of the number of flow channels, makes the overall structure simple, and reduces the difficulty of preparation.

[0284] like Figure 16 As shown, in the specific setting, the water channel component 300 and the resin tank 400 are both made of plastic material. Plastic material is easy to mold and is conducive to the construction of flow channels and the construction of complex shapes. In addition, the one-piece molding of plastic material can combine plastics of various materials together to form a compact and seamless product.

[0285] In specific applications, such as Figure 18 As shown, the first connection port 350 is a truncation, and the cross-sectional area of ​​the opening of the first connection port 350 in the cross-sectional direction of the resin tank 400 is less than or equal to the cross-sectional overlap between the first flow channel 310 and the resin filling portion 420. The waterway, through its connection with the resin tank 400, enables the basic functions of a water softener. That is, raw water can flow through the first flow channel 310 into the resin tank 400 in a forward direction, achieving softening. Salt water can also flow back from the first flow channel 310 to the salt mixing channel and into the central tube 410 in a reverse direction, achieving other functions. In this embodiment, the first connection port 350 is opened along the extension direction of the first flow channel 310. As long as the truncation does not exceed the corresponding range of the resin tank 400, the size of the first connection port 350 is not restricted, and the distribution of raw water through the first connection port 350 is not affected by the opening size.

[0286] It is understandable. Figure 18 As shown, in this embodiment, the portion of the entity forming the first flow channel 310 spans above the resin tank 400, so that the first flow channel 310 and the resin tank 400 have intersecting planes in the horizontal direction, and the intersecting plane is the above-mentioned cross-section. In other words, the portion of the entity structure of the first flow channel 310 is located inside the resin tank 400, and the outer portion of the resin tank 400 is the resin filling portion 420 filled with resin particles. The first connection port 350 can open an opening of any size on the entity portion located inside the resin tank 400, so that it is not restricted by the inner diameter of the first flow channel 310. Even on a first flow channel 310 with a smaller inner diameter, a larger first connection port 350 size can be opened along its own extension direction, thereby achieving a high-quality water distribution effect.

[0287] Specifically, in this embodiment, since part of the wall forming the first flow channel 310 spans above the resin tank 400, and a first connecting port 350 is opened on the wall above the resin tank 400, the part of the wall facing the resin tank 400 can be a notch structure. At this time, the size of the first connecting port 350 is equal to the overlapping part of the wall and the resin filling part 420 in the resin tank 400, which increases the contact area between the first connecting 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 from the first connecting port 350, enabling the water body to fully contact with the resin, thereby improving the softening efficiency and softening quality of the water body.

[0288] According to an embodiment provided by the present invention, a plurality of resin tanks 400 are connected to the main body 301. The plurality of resin tanks 400 are arranged in parallel and spaced apart along the extension direction of the first flow channel 310 or the extension direction of the second flow channel 320. The first connection end 330 and the second connection end 340 are both located on the same one of the plurality of resin tanks 400. The resin tank 400 is used to load resin, and the amount of resin loaded will directly affect the water quality treatment effect. In the related art, due to the influence of the assembly method, etc., it is usually set as one resin tank 400. If a resin tank 400 wants to load more resin particles, it needs to have a larger volume, which makes the entire component occupy a large space in the width direction, thereby making the overall structure complex and not conducive to installation. In this embodiment, the method of multiple resin tanks 400 can make it narrower in the width direction while having the same volume, which can facilitate the assembly of components.

[0289] When setting specific settings, such as Figure 1 Figure 18As shown, in this embodiment, there are two resin tanks 400, which are arranged side by side. When determining the number of resin tanks 400, the water treatment capacity requirements of the entire waterway plate and the design of the overall structural space occupied are generally taken into consideration. Therefore, in some specific designs, three, four, or more resin tanks 400 may be selected. It is understood that when adding resin tanks 400, the flow channel will be arranged in the longitudinal direction to achieve communication between the resin tanks 400 and the flow channel to form a waterway. The drawings in the embodiment description of this application only specifically illustrate the example of two resin tanks 400.

[0290] 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 in parallel along the horizontal straight direction. The fluids in the first flow channel 310 and the second flow channel 320 can both enter the resin tank 400 for processing, and then be output or input through the first connection end 330 and the second connection end 340 to realize positive circulation water flow direction or reverse circulation water flow direction.

[0291] When setting specific Figure 1 As shown, both the first connection end 330 and the second connection end 340 are provided with quick-connect sockets, each of which is provided with a quick-connect plug. The first connection end 330 and the second connection end 340 are connected to the adapter assembly 200 via the quick-connect plug. Typically, a water softener is installed in a relatively confined space, making assembly and disassembly difficult. In this embodiment, a quick-connect connection is used to facilitate assembly and disassembly.

[0292] In specific configurations, there are various types of quick-connect connectors, such as quick connectors, quick rotary connectors, quick clamp connectors, and compression connectors commonly used in pipe connections. In this embodiment, a socket is provided on the first connection end 330, a connector is provided on the adapter assembly 200, and an annular groove is provided on the connector. The connector is inserted into the first connection end 330, and then inserted into the socket via a snap-fit ​​piece. 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 connection port. When in operation, the snap-fit ​​piece is located within the groove to achieve snap-fit ​​connection. When disassembly is required, the snap-fit ​​piece can be removed to complete disassembly, simplifying the entire assembly and disassembly process.

[0293] like Figure 16 and Figure 18As shown, according to one embodiment of the present invention, a resin tank 400 is integrally formed with a water channel member 300. The resin tank 400 comprises a tank body and a cover. The tank body has a receiving cavity and an installation opening communicating with the receiving cavity. The cover is positioned over the installation opening to connect the cover and the tank body. After the tank body 400 and the water channel member 300 are integrally formed, the upper portion of the tank body and the water channel member 300 form a single structure. The cover is provided to facilitate installation of the water distributor and loading of the resin pellets, and the cover seals the resin tank 400.

[0294] The tank body is generally hollow and cylindrical, with a holding cavity formed within it. The holding cavity is the primary component of the resin tank 400 assembly, used to store the resin. Depending on the application, the holding cavity can be designed to have various shapes and sizes to accommodate varying resin volumes and performance requirements, and is not specifically limited here.

[0295] It is understandable that the resin tank 400 assembly may include one or more tank bodies, which are arranged in parallel. For ease of installation, the installation openings of the tank bodies are aligned and arranged toward the same side. In a specific application, a tank mouth is provided on the end face of one end of the tank body, and the tank mouth end is integrally formed with the waterway component 300. The tank mouth is used to allow and control the flow of fluid into and out of the accommodating cavity. The size and shape of the tank mouth can be adjusted according to actual needs to optimize the flow properties of the resin. At the same time, a connecting port 164 connected to the tank mouth is provided on the waterway plate or the pump body, thereby realizing waterway connection between the tank body and the waterway plate or the pump body; the tank body is provided with an installation opening at the end away from the waterway component 300. On the one hand, the installation opening can facilitate the setting of the forming process of the tank body, and on the other hand, it can facilitate the assembly and setting of other components of the tank body, such as a water distributor. The tank body is provided with bolt holes on the outer periphery of the end where the installation opening is provided.

[0296] like Figure 18 As shown, the cover is positioned over the mounting opening to seal the mounting opening and ensure relative sealing of the receiving cavity. The cover is axially connected and secured to the tank body via screws and other fasteners. It is understood that during use, the resin tank 400 assembly requires a certain pressure to propel the internal softening flow path. Therefore, when the resin tank 400 assembly is in an axially positioned tank opening or an axially positioned receiving cavity, a force is exerted between the cover and the tank body during operation. In the presence of unstable water pressure and the repeated application of this force, the bolted connection ensures a stable connection between the cover and the tank body.

[0297] Through the description of the above 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 control the water path switching on the one hand, and can control the opening of the sewage path 2107 in the adapter assembly 200 through the cooperation of the transmission mechanism 141 and the adapter assembly 200 on the other hand, thereby achieving control of the entire water path, simplifying the control logic, improving the control efficiency, reducing the setting of the device, and reducing the failure rate of the water path control assembly. Furthermore, the sewage control assembly 250 is a sewage pressure rod 251. The sewage pressure rod 251 realizes the opening of the sewage path 2107 by squeezing with the drive block 1433 on the driven gear 1431. It is achieved by mechanical transmission. The structure of the entire switch is simple and has strong reliability and stability.

[0298] The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be included in the scope of protection of the present invention.
