[0110] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0111] 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.

[0112] Typically, water softeners utilize resin replacement. This resin is a polymer with a unique structure and a positive surface charge. When hard water passes through an ion exchange resin column, the calcium and magnesium ions in the resin absorb and react with the positive charges on the resin surface, replacing the sodium ions already present. Water softening equipment requires multiple water paths for softening the water and regenerating the resin particles. Furthermore, it also requires the introduction of brine and water distribution during regeneration.

[0113] In the prior art, multiple water channel functions of a water softener are typically achieved by connecting a water channel component to a resin barrel. Specifically, the water channel component is integrally formed, such as by injection molding, with multiple flow channels constructed within the integrally formed water channel component. This requires complex mold design, increasing production costs and time.

[0114] In the related art, in order to realize the switching of the water flow direction in the resin barrel of the water softener, that is, the forward circulation and reverse circulation of the water in the resin barrel, the passages and some functional components are often integrated into the water channel components, which further makes the flow channels in the water channel components complicated, makes the mold extremely complicated, increases the difficulty of preparation, and increases the manufacturing cost.

[0115] In response to the problems in the related art, referring to Figures 1 to 3, the present application provides a flow channel assembly for cooperating with a resin barrel 600, comprising a first flow channel tube 100, a first connecting tube 300, a second flow channel tube 200, and a second connecting tube 400 to form a flow passage. The first flow channel tube 100 is provided with a first connecting port 120 for communicating with the resin filling portion of the resin barrel 600; the first connecting tube 300 is fixedly connected to the first flow channel tube 100, and the two are connected to each other, wherein the first connecting tube 300 is used for fluid input or fluid output; the second flow channel tube 200 is provided with a second connecting port 220 for communicating with the central tube 700 of the resin barrel 600; the second connecting tube 400 is fixedly connected to the second flow channel tube 200, and the two are connected to each other, wherein the second connecting tube 400 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 wash in the water softener. Therefore, the water channel component usually integrates multiple flow channels to form an integrated structure, which undoubtedly requires complex molding molds to construct multiple flow channels. In this embodiment, two flow channel pipes, namely the first flow channel pipe 100 and the second flow channel pipe 200, are used. Connecting ports are respectively opened on the two flow channel pipes, namely the first connecting port 120 and the second connecting port 220. The two connecting ports can realize the connection between the two flow channel pipes and the resin barrel 600, thereby realizing the switching of the flow direction in the resin barrel 600.

[0116] It is understood that in this embodiment, the waterway is guided by the first flow channel tube 100 and the second flow channel tube 200, and by connecting the first connecting tube 300 to the first flow channel tube 100 and the second flow channel tube 200 to the second flow channel tube 200, the fluid enters the resin barrel 600 by selecting the first connecting tube 300 or the second connecting tube 400 to switch the flow direction of the waterway, thereby satisfying the switching of the five functional waterways of water supply, backwash, regeneration, water replenishment, and forward wash in the water softener. It can be seen that in this embodiment, the construction of multiple flow channels can be achieved by connecting the pipes to the resin barrel 600, avoiding the complex structural design of the mold. The entire circuit is composed of a small number of pipes, which simplifies the structure of the flow channel and reduces the difficulty and manufacturing cost of preparation.

[0117] It can be understood that the flow direction in which water enters from the top of the resin filling part and flows through the resin particles and then is discharged from the central tube 700 is usually defined as the forward flow direction. The flow direction in which water enters from the top of the central tube 700 and enters the bottom through the central tube 700 and then is discharged from the bottom of the resin filling part after rising through the resin particles is defined as the reverse flow direction. Among the five functions of the water softener, the water supply and water replenishment are forward flows, and the remaining functional channels are reverse flows.

[0118] In a specific configuration, during water supply (forward flow), raw water enters the first flow tube 100 through the first connecting tube 300 and is softened by the resin particles in the resin barrel 600. The treated water then rises through the central tube 700 and is output from the second connecting tube 400 through the second flow tube 200. In this case, the first connecting tube 300 is used for fluid input, while the second connecting tube 400 is used for fluid output. During regeneration (reverse flow), brine enters the second flow tube 200 through the second connecting tube 400 and enters the bottom of the resin barrel 600 through the central tube 700. The brine at the bottom rises along the outer portion of the resin tube to clean the resin particles, then enters the first flow tube 100 and is output from the first connecting tube 300 within the first flow tube 100. In this case, the first connecting tube 300 is used for fluid output, while the second connecting tube 400 is used for fluid input. It can be understood that the switching of the flow direction in the resin barrel 600 is achieved through the access selection of the two connecting pipes, and the entire flow channel is constructed through two flow channel pipes, which simplifies the overall structure and reduces the preparation difficulty and manufacturing cost.

[0119] In specific applications, the first flow channel tube 100, the second flow channel tube 200, the first connecting tube 300, and the second connecting tube 400 can be prepared separately, and connecting ports are respectively opened on the first flow channel tube 100 and the second flow channel tube 200 to respectively achieve communication with the resin filling part of the resin barrel 600 and the center tube 700. Specifically, the first connecting tube 300 can be connected to the first flow channel tube 100 by welding or the like to form a first tube group, and the second connecting tube 400 can be connected to the second flow channel tube 200 to form a second tube group. The two tube groups are arranged and respectively connected to multiple through bodies. It can be understood that the solution of this embodiment can realize the assembly of products through modular operations during production, and can realize the production and assembly of multiple modules at the same time, and finally form an integral product, which can improve manufacturing and production efficiency, shorten the design and development cycle of the product, and facilitate resource utilization and recycling.

[0120] It can be understood that the resin barrel 600 in each embodiment described in this application can adopt a conventional resin barrel 600 structure, that is, it has a barrel body structure for filling resin particles, and also has an independent central tube 700 in the barrel body. The resin filling part is located in the outer part of the central tube 700, and the water channel realizes softening and other functions by contacting the resin particles in the resin barrel 600.

[0121] In some specific applications, as shown in FIG2 , at least one of the partial body of the first flow tube 100 and the partial body of the second flow tube 200 is located in the resin barrel 600. The outer portion of the resin barrel 600 is filled with resin particles. The center of the resin barrel 600 has a central tube 700. The central tube 700 at the center position can make the fluid output by the central tube 700 evenly contact the resin particles around it. The outer portion of the resin barrel 600 needs to be connected to one of the flow tubes, and the central portion of the resin barrel 600, that is, the central tube 700, also needs to be connected to a flow tube. In this embodiment, the tube body portion of at least one flow tube is set in the resin barrel 600. This allows the connecting port connected to the outer portion to be directly opened on the tube body, reducing the difficulty of preparing the connecting port.

[0122] In a specific configuration, as shown in FIG2 , a portion of the first flow conduit 100 and a portion of the second flow conduit 200 are both located within the resin barrel 600. A first communication port 120 is defined on the wall of the first flow conduit 100, communicating with the outer portion of the resin barrel 600. It will be appreciated that placing both flow conduits within the resin barrel 600 can further shorten the waterway flow path, thereby reducing energy loss during the flow process and improving water delivery performance.

[0123] In specific applications, as shown in Figure 2, the first connecting port 120 is opened along the extension direction of the first flow channel tube 100, and the maximum dimension of the first connecting port 120 in the extension direction of the first flow channel tube 100 is less than or equal to the dimension of the first flow channel tube 100 in the extension direction located in the resin barrel 600. The diameter of the first connecting port 120 will affect the sufficiency and uniformity of the contact with the resin, because the first connecting port 120 is directly connected to the resin filling part. If the diameter of the first connecting port 120 is too small, then the size of the water outlet will be affected. An excessively small water outlet will limit the water distribution effect, making it difficult to achieve uniform contact with the resin, resulting in insufficient contact. In this embodiment, the first connecting port 120 can be opened along the extension direction of the tube body, and since a portion of the tube body is located in the resin barrel 600, it can be flexibly opened as needed, so that even if the diameter of the tube body is small, the first connecting port 120 can have a larger diameter, thereby improving the water distribution effect.

[0124] In some specific examples, the cross-sectional area of ​​the first connecting port 120 is greater than or equal to the caliber area of ​​the longitudinal cross-section of the first flow channel tube 100. By limiting the size of the first connecting port 120, it is possible to improve the sufficiency of the water body and the resin particles, thereby improving the water delivery performance in the pipeline system. It is understandable that a smaller caliber of the connecting port will have a certain impact on the water delivery performance, including changes in flow rate, increased pressure loss, diversion effect, and possible increase in noise and vibration. In this embodiment, since the first connecting port 120 can be opened along the extension direction of the first flow channel tube 100, and the caliber of the first connecting port 120 is larger than the inner diameter of the first flow channel tube 100, the above-mentioned problems are avoided, and by opening along the extension direction of the flow channel tube, its distribution range in the outer part of the resin barrel 600 can be improved, so that the water body and the resin particles are in full contact.

[0125] It is understood that in this embodiment, since part of the pipe body is located within the resin barrel 600, it can be opened along the extension direction of the flow channel tube. This opening method does not affect the water supply of the entire pipeline system. This opening method can achieve a larger water outlet diameter, allowing for contact with a large area of ​​resin particles, thereby improving the uniformity and adequacy of contact between water and resin particles.

[0126] In specific applications, the edges of the first communication opening 120 and / or the second communication opening 220 can be configured as an overall rounded structure. This rounded design can reduce pressure loss when fluid passes through the opening. Compared to sharp or right-angled edges, rounded edges can reduce resistance and friction between the fluid and the edge, thereby reducing pressure loss. Rounded edges can also better guide fluid flow, reduce fluid separation and turbulence, improve fluid stability and delivery efficiency, and avoid fluid separation or turbulence.

[0127] According to one embodiment provided herein, the axis of the first connecting pipe 300 is perpendicular to the axis of the first flow channel pipe 100, and the axis of the second connecting pipe 400 is perpendicular to the axis of the second flow channel pipe 200. The first connecting pipe 300 and the second connecting pipe 400 are used to connect to the valve body portion, and the valve body portion is used to switch the water path and selectively input the water path through the first connecting pipe 300 or the second connecting pipe 400. In this embodiment, the vertical arrangement of the first connecting pipe 300 and the first flow channel pipe 100 shortens the water path entering the first flow channel pipe 100, thereby avoiding loss of water transmission performance during the water transmission process. The vertical arrangement can further reduce the difficulty of manufacturing because, compared to an inclined arrangement, the vertical arrangement is easier to position, can achieve fluid introduction with less material, and can better achieve connection with the valve body portion. Similarly, the vertical arrangement of the second connecting pipe 400 and the second flow channel pipe 200 can also reduce its difficulty in manufacturing.

[0128] In a specific embodiment, as shown in FIG1 , the first connecting tube 300 and the second connecting tube 300 protrude from the highest plane formed between the first flow channel tube 100 and the second flow channel tube 200, which can facilitate the access of the valve body. In addition, quick-plug holes are provided on the tube body of the first connecting tube 300 and the tube body of the second connecting tube 400. Through the provision of the quick-plug holes, they can be quickly connected with the valve body, which is beneficial to the connection of functional components such as the valve body. In a further example, a protruding structure is also provided on the tube body of the first connecting tube 300 and the tube body of the second connecting tube 400. The protruding structure is provided along the extension direction of the tube body. On the one hand, the protruding structure can improve the strength of the tube body, and on the other hand, it can cooperate with the valve body and other functional components for guidance and insertion.

[0129] According to an embodiment provided in the present application, the runner assembly also includes an adapter 500 having at least one opening 530 for cooperating with a resin barrel 600, each opening 530 having a first connecting port 120 and a second connecting port 220, so that the first connecting tube 300 is connected to the resin filling part through the first runner tube 100, and the second connecting tube 400 is connected to the center tube 700 through the second runner tube 200. It is understandable that the resin barrel 600 needs to be used for water treatment, and the resin barrel 600 has a resin filling portion filled with resin particles, which makes the resin barrel 600 have a certain mass, which requires the resin barrel 600 to have a relatively stable connection structure. In this embodiment, an adapter 500 is provided on the lower end surface of the channel portion, so that the adapter 500 is located at the lower end of the channel portion as a whole, and an opening 530 is provided on the adapter 500. The connection of the resin barrel 600 is achieved through the opening 530, which can improve the stability of the connection of the resin barrel 600. The top of the resin barrel 600 has a barrel mouth, and the first connecting port 120 and the second connecting port 220 are both located in the barrel mouth, so that when the resin barrel 600 is connected to the opening 530, the water entering the opening 530 can enter the resin barrel 600.

[0130] In a specific configuration, a portion of the first flow tube 100 and a portion of the second flow tube 200 are both located within the opening 530. The opening 530 is used to connect to the resin barrel 600, specifically to the barrel opening of the resin barrel 600. In this embodiment, the tubes of the two flow tubes are located within the opening 530, and the portions of the tubes are exposed to the resin barrel 600 through the opening 530. This facilitates the configuration of the opening 530 and can shorten the waterway.

[0131] In a specific application, the adapter 500 includes a main plate 510, one surface of which has a raised edge portion 520 defining an opening 530. The other surface of the main plate 510 is connected to the first flow conduit 100 and the second flow conduit 200. The adapter 500 is used to connect to the resin barrel 600 and maintain the stability of the connection. In this embodiment, the edge portion 520 on one surface of the main plate 510 is formed to form an opening 530, through which the resin barrel 600 is connected, thereby improving the structural stability of the entire flow conduit assembly.

[0132] In some specific embodiments, as shown in FIG. 1 and FIG. 3 , the edge portion 520 forms a circular opening 530 , and threads may be machined on the inner wall surface of the edge portion 520 to achieve connection between the resin barrel 600 and the opening 530 .

[0133] In a specific example, referring to Figures 1 and 2 , the adapter 500 has two openings 530, which are arranged side by side. The two openings 530 can be connected to the resin barrel 600. Specifically, the first flow tube 100 has two first communication ports 120, which correspond one-to-one with the resin barrel 600. The second flow tube 200 has two second communication ports 220, which correspond one-to-one with the resin barrel 600. The first connecting tube 300 is located between the two first communication ports 120, and the second communication port 220 is also located between the two communication ports. It can be understood that by arranging the first connecting tube 300 between two adjacent first communication ports 120, the fluid entering the first flow tube 100 from the first connecting tube 300 can be diverted through the two first communication ports 120, thereby achieving a more even delivery of the fluid to the two resin barrels 600. Similarly, the provision of the second connecting pipe 400 can also achieve relatively uniform delivery of the fluid to the central pipes 700 of the two resin barrels 600, which enables the input fluid, such as raw water, to fully contact with the resin particles, thereby improving the quality of water softening treatment.

[0134] According to one embodiment provided herein, the body of the second flow conduit 200 includes a main body and a protrusion 230. The sidewalls of the main body extend parallel to the main body's axis. The sidewalls of the protrusion 230 protrude from the main body and communicate with the main body. The protrusion 230 also communicates with the center tube 700. The center tube 700 is typically located at the center of the resin barrel 600. In this embodiment, the protrusion 230 allows the fluid within the second flow conduit 200 to be introduced into the center tube 700.

[0135] It can be understood that by having a protrusion 230 on the second flow channel tube 200, a certain distance is provided between the first flow channel tube 100 and the second flow channel tube 200, and this distance forms an installation space for functional components such as the valve body, thereby enabling a compact layout of the product.

[0136] In a specific configuration, the protrusion 230 is integrally formed with the second flow channel tube 200, thereby reducing the number of parts and improving the stability of the piping system. Furthermore, in application, the first flow channel tube 100 and the second flow channel tube 200 can be made of materials such as hard plastic, or, in other specific applications, the first flow channel tube 100 and the second flow channel tube 200 can also be made of metal. In some examples, the first flow channel tube 100 and the second flow channel tube 200 can be made of the same material. Of course, in other examples, the first flow channel tube 100 and the second flow channel tube 200 can also be made of different materials.

[0137] The protrusion 230 can be a tubular structure. Alternatively, it can be a non-tubular structure. As shown in Figures 2 and 5 , the protrusion 230 is an annular wall structure. When the protrusion 230 is a tubular structure, the second communication port 220 is located at the bottom of the protrusion 230, allowing the end of the central tube 700 to be inserted into the second communication port 220 for communication. When the protrusion 230 is an annular wall structure, the annular sidewall structure forms the second communication port 220. In this case, the second communication port 220 is connected to the second flow tube, and the end of the central tube 700 is connected to the second communication port 220 to form a circulating waterway.

[0138] In the specific setting, the diameter of the second connecting port 220 is greater than or equal to the inner diameter of the central tube 700. The upper end of the central tube 700 is connected to the second connecting port 220, and the lower end of the central tube 700 is connected to the barrel body of the resin barrel 600, so that the fluid can be input from the central tube 700 to the bottom of the resin barrel 600, or the fluid rises from the bottom of the resin barrel 600 along the central tube 700, that is, the second connecting port 220 serves as a connecting hole between the central tube 700 and the second flow channel tube 200. In this embodiment, the water supply performance of the pipeline system can be improved by limiting the diameter of the second connecting port 220 to be greater than or equal to the diameter of the central tube 700. The specific principle is consistent with the first connecting port 120. If the diameter of the first connecting port 120 is smaller than the central tube 700, it will affect the water supply performance of the pipeline system.

[0139] According to one embodiment provided herein, at least a portion of the first flow conduit 100 and at least a portion of the second flow conduit 200 are located within an adapter 500. The two flow conduits need to flow through a large volume of water during normal operation, requiring them to have a stable structure. In this embodiment, when the flow conduits are connected to the adapter 500, at least a portion of the conduits is located within the adapter 500. This increases the surface area of ​​the connection between the adapter 500 and the two conduits, thereby improving the stability of the connection.

[0140] It is understandable that, in a specific setting, the entire tube bodies of the two flow channel tubes can be immersed in the adapter 500 for connection. This connection method can make the structure of the flow channel tubes more stable. The entire immersion method requires the adapter 500 to have a sufficient thickness, which will increase the material used for the adapter 500, and the immersion method is inconvenient to operate during processing. Referring to Figures 1 and 3, in this embodiment, part of the tube body of the first flow channel tube 100 and the second flow channel tube 200 protrudes from the plane of the main plate 510 of the adapter 500, and the remaining part of the tube body is located in the adapter 500. This method can not only maintain the connection strength between the flow channel tube and the adapter 500, but also facilitate connection processing.

[0141] In a specific configuration, the upper surface of the first flow tube 100 protruding from the adapter 500 includes a first flat surface 110, and the upper surface of the second flow tube 200 protruding from the adapter 500 includes a second flat surface 210. The first flat surface 110 and the second flat surface 210 are coplanar. The flow assembly, which guides the flow of water, is connected to the resin barrel 600. A valve body is often connected to the flow assembly, which is used to actively control and switch the waterway. In this embodiment, the first and second flow tubes 100, 200 are provided with the first and second flat surfaces 110, 210, which facilitate the assembly of the valve bodies.

[0142] It is understood that the wall surface of the tube body is typically curved, and this curved surface is higher than the plane of the main plate 510, which hinders the assembly of the valve body. Furthermore, the provision of two planes increases the contact surface between the valve body and the planes after the valve body is connected, improving the load-bearing capacity of the valve body and thereby enhancing the stability of the overall connection structure. Furthermore, the provision of two planes facilitates direct connection of the valve body, making the overall structure more compact and reducing the product's volume.

[0143] In a specific application, the first flat surface 110 is located on the first flow conduit 100 on both sides of the first connecting tube 300, and the second flat surface 210 is located on the second flow conduit 200 on both sides of the second connecting tube 400. The provision of the flat surface reduces the wall thickness of the flow conduit. In this embodiment, the first connecting tube 300 and the second connecting tube 400 do not have flat surfaces, which increases the strength of the connecting tubes and further improves the overall stability.

[0144] It can be understood that the first connecting pipe 300 and the second connecting pipe 400 are used to directly communicate with the valve body part. The water channel impact force at this position is relatively large. In this embodiment, the thickness of the pipe body is provided at this position, thereby increasing the overall structural strength and making the structure more stable.

[0145] According to an embodiment provided by the present application, the first flow channel tube 100 and the second flow channel tube 200 are arranged in parallel. The parallel arrangement facilitates connection on the one hand. When connecting, one of the flow channel tubes can be aligned with the reference for connection, and the remaining one can be processed based on the positioned flow channel tube as the reference, which reduces the difficulty of preparation. On the other hand, it facilitates the overall layout. The parallel arrangement enables it to have a better load-bearing capacity in the space between the two tube bodies. For example, in the above embodiment, by setting a plane on the two tube bodies, this makes the connection surface with the valve body part roughly equal, which can improve the stability after installation.

[0146] In specific applications, the first connecting pipe 300 and the second connecting pipe 400 are offset on the same resin barrel 600, and the two parallel flow pipes are located on both sides of the resin barrel 600. In this way, an avoidance space is formed above the remaining resin barrel 600, and the valve body part can be installed in the avoidance space, further making the overall structure compact.

[0147] In a specific configuration, the first runner tube 100 and the second runner tube 200 are symmetrically arranged in a longitudinal section at the center of the opening 530. It is understood that since portions of the two runner tubes are located within the resin barrel 600, the first runner tube 100 and the second runner tube 200 do not exceed the outer diameter of the resin barrel 600. In other words, the entire first runner tube 100 and the entire second runner tube 200 are both located within the barrel body, which further makes the overall structure more compact.

[0148] In response to the problems in the related art, referring to Figures 2 and 3, the present application provides a flow channel assembly for cooperating with multiple resin barrels 600, including a first flow channel tube 100, a second flow channel tube 200, a first connecting tube 300 and a second connecting tube 400 to form a flow passage. Specifically, the first flow channel tube 100 has a plurality of first connecting ports 120, and the plurality of first connecting ports 120 correspond one-to-one to the plurality of resin barrels 600, and the first connecting ports 120 are used to communicate with the resin filling part of the resin barrel 600; the second flow channel tube 200 has a plurality of second connecting ports 220, and the plurality of second connecting ports 220 correspond one-to-one to the plurality of resin barrels 600, and the second connecting ports 220 are used to communicate with the central tube 700 of the resin barrel 600; the first connecting tube 300 is arranged on the first flow channel tube 100, And it is located between two adjacent first connecting ports 120, the first connecting tube 300 is connected to the resin filling part of the resin barrel 600 through the first flow channel tube 100, and the first connecting tube 300 is used for fluid input or fluid output; the second connecting tube 400 is arranged on the second flow channel tube 200 and is located between two adjacent second connecting ports 220, the second connecting tube 400 is connected to the central tube 700 of the resin barrel 600 through the second flow channel tube 200, and the second connecting tube 400 is used for fluid output or fluid input.

[0149] In a specific example, as shown in Figures 2 and 4, the second communication port 220 is a strip-shaped through-hole structure, and the top of the central tube 700 is connected to the second communication port 220, so that the fluid in the second flow channel tube 200 can be input into the central tube 700. It will be understood that in this embodiment, the second communication port 220 is provided by forming a strip-shaped hole. This method avoids the need to connect a physical pipeline to the second flow channel tube 200. It should be noted that when connecting a physical pipeline, an opening on the second flow channel tube 200 is required for connection, which increases the processing steps of the second flow channel tube 200 and increases the complexity of the mold.

[0150] In this embodiment, a strip-shaped through hole is formed by setting an annular wall structure below the position of the second connecting port 220, and the strip-shaped through hole is connected to the second connecting port 220 on the central tube 700, so that the fluid of the second flow channel tube 200 enters the central tube 700, which simplifies the preparation process and reduces the complexity of the molding mold.

[0151] It is understood that the protrusion 230 may also be a tubular structure. In this case, the protrusion 230 and the second flow conduit 200 form an integrated tubular structure, and the diameter of the connecting interface between the protrusion 230 and the second flow conduit 200 is larger than the inner diameter of the central tube 700. When the protrusion 230 is configured as a tubular structure, the protrusion 230 and the second flow conduit 200 intersect at an interface. If this interface is smaller than the diameter of the central tube 700, it will still affect the water conveyance performance of the pipeline.

[0152] In the specific configuration, as shown in FIG1 , the adapter 500 includes a main plate 510 having a raised edge portion 520 on one side thereof, the edge portion 520 defining an opening; the other side of the main plate 510 is connected to the first flow conduit 100 and the second flow conduit 200. The adapter 500 is used to connect to the resin barrel 600 and maintain the stability of the connection. In this embodiment, by having the edge portion 520 on one side of the main plate 510, the edge portion 520 can enclose an opening through which the resin barrel 600 is connected, thereby improving the structural stability of the overall flow conduit assembly.

[0153] It is understandable that the first main plate 510 and the edge portion 520 may be integrally formed, or may be connected by welding or other methods.

[0154] In a specific application, as shown in FIG. 2 , the edge portion 520 forms a circular opening, and threads may be processed on the inner wall surface of the edge portion 520 to achieve connection between the resin barrel 600 and the opening.

[0155] In the specific setting, referring to Figures 6 and 7, the resin barrel 600 and the adapter 500 can also be set as an integrally formed structure. Specifically, the first flow channel tube 100, the second flow channel tube 200, the adapter 500 and the resin barrel 600 are integrally formed. In this way, the overall structure can be made more stable, and the stability and reliability of the flow channel assembly are improved. The present application also provides a water softener, comprising a resin barrel 600 and a flow channel assembly as provided in any of the above embodiments, wherein the flow channel assembly is located on one side of the resin barrel 600 in the axial direction, and the flow channel assembly is fixedly connected to the resin barrel 600.

[0156] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment realizes the construction of the flow channel through two flow channel pipes, and forms a water channel by arranging connecting pipes on respective flow channels. When softening is required, raw water is input through the first connecting pipe 300 and output through the second connecting pipe 400. When the resin needs to be regenerated, brine is input through the second connecting pipe 400 and output through the first connecting pipe 300. Thus, the requirements for multiple water channel circulation of the water softener are achieved by connecting a small number of pipes, which simplifies the overall structure, makes it easy to prepare, and has low manufacturing cost.

[0157] In response to the problems in the related art, referring to Figures 8-10, the present application provides a sewage discharge system for cooperating with the sewage discharge passage in the first valve body 300A, including a rotating part 110A and a pressure rod assembly 200A; the pressure rod assembly 200A is arranged on one side of the rotating part 110A, and a protrusion 130 is provided on the rotating part 110A, and the protrusion 130 can squeeze the pressure rod assembly 200A to open the sewage discharge passage 310. In the normal state, the sewage discharge channel 310 is closed. Only when sewage discharge is required, the sewage discharge channel 310 will be opened for sewage discharge operation. In this embodiment, in the normal state, the protrusion 130 and the pressure rod assembly 200A are not in contact. When sewage discharge is required, the rotating part 110A is rotated, and the protrusion 130 is abutted against the sewage discharge pressure rod. When abutting, it can generate thrust on the pressure rod assembly 200A, so that the pressure rod assembly 200A moves. After the pressure rod assembly 200A moves, the sewage discharge channel 310 can be 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.

[0158] It is understood that the sewage discharge pressure rod is disposed in the sewage discharge channel 310. Under normal circumstances, the pressure rod assembly 200A can close the sewage discharge channel 310. Only when the sewage discharge channel 310 needs to be opened will the protrusion 130 be opened to open the sewage discharge channel 310. In addition, in this embodiment, the pressure rod assembly 200A can be a conventional sewage discharge pressure rod. The conventional sewage discharge pressure rod includes a rod body, and the first end of the rod body has a sealing head. When it does not need to be opened, the sealing head can block the sewage discharge channel 310. When it needs to be opened, the sewage discharge channel 310 is opened through the action of an external force. As for the specific sewage discharge pressure rod, those skilled in the art should be aware of its specific structure, so it will not be further described.

[0159] In a specific configuration, the sewage system of this embodiment is used in a water softener to open the sewage channel 310 in the water softener. For example, in a specific application, the position of the protrusion 130 on the rotating component 110A is configured as a salt absorption position and controlled by a control system. That is, when the control system issues a signal indicating the need for salt absorption, the rotating component 110A rotates, and the protrusion 130 abuts against the pressure rod assembly 200A, thereby opening the sewage channel 310. When the sewage channel 310 is no longer required to be opened, the rotating component 110A is controlled to rotate so that the protrusion 130 and the pressure rod assembly 200A are misaligned, and the pressure rod assembly 200A can then reclose the sewage channel 310.

[0160] It is understood that in this embodiment, the opening of the drain channel 310 is achieved by providing the protrusion 130 on the rotating component 110A. The overall structure is simple and efficient, and can quickly respond to achieve rapid opening of the drain channel 310. In addition, the opening of the drain channel 310 is achieved by mechanical transmission, which has higher reliability and anti-interference capabilities.

[0161] According to one embodiment provided herein, there are multiple protrusions 130, which are arranged at intervals. In an overall product, sewage discharge is often required in multiple states. In this embodiment, multiple protrusions 130 are provided on the rotating component 110A to enable sewage discharge in different states, thereby improving the applicability of the sewage discharge system in this example.

[0162] In the specific configuration, as shown in FIG10 , two protrusions 130 are provided on the rotating component 110A. The two protrusions 130 are located at different positions. By distributing the protrusions 130 at different positions, the two protrusions 130 can respectively control the opening of the sewage discharge channel 310 in at least two states. Of course, the number of protrusions 130 can also be three or four, and the protrusions 130 are generally distributed in different positions to correspond to different states. The drawings in the specification of this application only illustrate the configuration of two protrusions 130.

[0163] In specific applications, the two raised portions 130 have the same structure and the same material. Of course, the two raised portions 130 can also have different structures, as shown in Figure 10. In some examples, the minimum distances between the abutting ends of the plurality of raised portions 130 and the pressure rod assembly 200A are roughly the same. In theory, the minimum distances between the plurality of raised portions 130 and the pressure rod assembly 200A are equal, but due to relationships such as processing and assembly, there is often a certain error, so the minimum distances are roughly the same. It is understandable that this minimum distance can reflect the depth of the action of the pressure rod assembly 200A. Generally speaking, the pressure rod assembly 200A has a fixed action depth to achieve complete sealing for the drain channel 310. By limiting the equal minimum distances, the drain channel 310 can be stably opened when opened, and can ensure that it is opened to a fully open state, thereby improving the stability of its opening.

[0164] According to an embodiment provided by the present application, as shown in FIG8 , a second valve body 100A is further included. The second valve body 100A is located on one side of the first valve body 300A and is interconnected. A rotating component 110A is provided on the second valve body 100A, and a driving device 120A is provided on the second valve body 100A. The driving device 120A is in transmission connection with the rotating component 110A. The second valve body 100A is used to control the switching of the waterway. Specifically, the second valve body 100A controls the switching of the waterway through the driving device 120A. When the waterway is switched, the rotating component 110A is driven to rotate. The rotation of the rotating component 110A can cause the protrusion 130 to rotate accordingly, thereby achieving the opening of the corresponding sewage discharge channel 310 while switching the waterway, simplifying the control system and improving the reliability of the control.

[0165] In a specific application, the two protrusions 130 on the rotating component 110A can realize the opening of the sewage discharge channel 310 in the salt absorption position and the backwash position of the soft water valve.

[0166] Referring to Figure 15 , the arrows in the figure represent the flow direction of the waterway. Specifically, the second valve body 100A is connected to the first valve body 300A. The second valve body 100A contains a valve core, which is connected to the drive device 120A via a rotating component 110A. The valve core has multiple waterway channels, which can switch between multiple waterways when the drive device 120A is actuated. The first valve body 300A is equipped with a pressure rod assembly 200A and an ejector 330. The ejector 330 is connected to the salt tank 700A via a pipeline. The lower portion of the first valve body 300A is connected to the resin tank 600A via a waterway component 500A. Furthermore, the second valve body 100A is constructed with components that are connected to the first valve body 100A, the waterway component 500A, and the salt tank 700A. When the valve core in the second valve body 100A is in the salt absorption position, a protrusion on the rotating part 110A cooperates with the pressure rod assembly 200A to open the drain channel 310 and cause the ejector 330 to generate negative pressure to continuously absorb salt. The specific water flow process is as follows: the input raw water passes through the valve core of the second valve body 100A and is input into the channel with the ejector 330 in the first valve body 300A. The ejector 330 generates negative pressure, causing the saturated salt water in the salt tank 700A to be sucked into the channel with the ejector 330. The salt water sucked into the channel is mixed with the raw water and then passes through the water channel component 500A to reach the central pipe 610 in the resin tank 600A. The salt water rises along the resin filling part through the bottom of the central pipe 610 and the rising mixed liquid enters the first valve body 300A. At this time, the drain channel 310 in the first valve body 300A has been opened, and the mixed liquid is discharged through the drain channel 310. It can be seen that the entire control process can realize the opening of the sewage channel 310 by the second valve body 100A when controlling the water channel switching. The opening of the sewage channel 310 does not require an independent control system to control, which simplifies the construction of the control system and reduces the difficulty of preparation.

[0167] Referring to Figure 16 , the arrows in the figure represent the flow direction of the waterway. When the valve core in the second valve body 100A is in the backwash position, another protrusion on the rotating component 110A engages with the pressure rod assembly 200A, opening the drain channel 310. The specific waterway flow process is as follows: raw water is input through the valve core of the second valve body 100A and input into another channel in the first valve body 300A. This channel directly connects to the central tube 610 in the resin tank 600A. After passing through the central tube 610, the raw water enters the bottom of the resin tank 600A and rises from the bottom through the resin filling portion. In this state, the drain channel 310 is open, and the rising mixed liquid can be directly discharged through the drain channel 310.

[0168] It can be understood that in this embodiment, the protrusions 130 in different positions can correspond to multiple functional states that require the sewage channel 310 to be opened. When the valve core in the second valve body 100A is in the corresponding water channel state, the protrusion 130 can cooperate with the pressure rod assembly 200A to realize the opening of the sewage channel 310. The entire process does not require an additional control path, simplifies the control system, and improves the overall reliability through mechanical transmission opening.

[0169] In the specific configuration, as shown in Figures 8 and 9 , the rotating component 110A includes a transmission gear, and the driving device 120A has a drive gear, which meshes with the transmission gear for transmission. When the second valve body 100A switches the water path, it must overcome factors such as the resistance of the water within the valve core. Therefore, a certain torque is generally required to drive the valve core. In this embodiment, the gear meshing transmission method can flexibly achieve different torque requirements by adjusting the transmission ratio.

[0170] In a specific application, as shown in FIG8 , the ratio of the driving gear to the transmission gear is much greater than 1. This arrangement enables the transmission gear to have a larger torque in a smaller space to drive the valve core and reduce the volume of the overall product.

[0171] According to an embodiment provided by the present application, as shown in FIG10 , the raised portion 130 includes an abutting structure having an arcuate abutting surface. The abutting surface includes a mating abutting section 1301 in the middle and guide sections 1302 on both sides. The minimum distance L1 between the guide section 1302 and the end of the pressure rod assembly 200A that is mated is greater than the minimum distance L2 between the mating abutting section 1301 and the end of the pressure rod assembly 200A that is mated. In FIG10 , the arrow on the transmission gear indicates that when the guide section 1302 rotates a certain angle, i.e., the position indicated by the dotted line in the figure, the guide section 1302 is approximately perpendicular to the pressure rod assembly 200A, and the minimum distance at this time is L1 in the figure. The abutting section 1301 is in the position indicated by the solid line, and the minimum distance between the guide section 1302 and the pressure rod assembly 200A is L2 in the figure. The pressure rod assembly 200A is located on one side of the rotating part 110A, that is, the pressure rod assembly 200A is located in the radial direction of the rotating part 110A. When the rotating part 110A rotates, it cooperates with the pressure rod assembly 200A and can achieve extrusion of the pressure rod assembly 200A. In this embodiment, the abutment surface between the protrusion 130 and the pressure rod assembly 200A is set to an arc surface. The setting of the arc surface can improve the service life of the pressure rod assembly 200A and prevent the pressure rod from being gradually damaged due to extrusion during the rotation process.

[0172] It can be understood that the raised portion 130 in this embodiment has a guide section 1302 and a mating abutment section 1301, and the guide section 1302 and the mating abutment section 1301 together form an arcuate surface. When the rotating portion rotates, the pressure rod assembly 200A first contacts the guide section 1302 and gradually approaches the mating abutment section 1301 during the rotation process. After reaching the mating abutment section 1301, the pressure rod assembly 200A is completely pressed down, thereby achieving complete opening of the sewage discharge channel 310.

[0173] In specific configuration, as shown in FIG10 , the abutment structure of the protrusion 130 is connected to the rotating component 110A via a connecting rib 150. In other words, the connecting rib 150 is connected to the transmission gear and reinforces the abutment structure, thereby providing greater strength and extending the service life of the protrusion 130. In a specific application, the two protrusions 130 have different specifications, with one protrusion 130 having a longer guide section 1302.

[0174] It is understandable that the protrusion 130 needs to withstand a certain force when it is in abutment with the pressure rod assembly 200A for a long time. In this embodiment, the protrusion 130 has a stronger structural strength through the setting of the connecting rib 150, thereby making the protrusion 130 more stable.

[0175] According to one embodiment provided herein, as shown in FIG10 , a positioning portion 140 is further included. Positioning portion 140 is disposed on rotating component 110A, spaced apart from protrusion 130, and is used to sense the rotational position of rotating component 110A. The position of the valve core of second valve body 100A during waterway switching is key to controlling the waterway switching. In this embodiment, by disposing positioning portion 140 on rotating component 110A, i.e., on the transmission gear, positioning portion 140 can sense its position during rotation, thereby improving the accuracy of opening of sewage discharge channel 310.

[0176] In a specific configuration, the positioning portion 140 can be a magnet or other component. A control panel is disposed below the rotating component 110A. The control panel is equipped with multiple Hall effect sensors, each corresponding to a different waterway channel. When the rotating component 110A rotates, the positioning portion 140 rotates accordingly, thereby generating a sensing signal between the Hall effect sensors and the positioning portion 140, thereby achieving position control. For example, the control panel includes a Hall effect sensor corresponding to the salt absorption position. When the rotating component 110A rotates to the Hall effect sensor position, a protrusion 130 on the rotating component 110A precisely abuts and cooperates with the pressure rod assembly 200A, thereby accurately opening the sewage discharge channel 310 in the salt absorption position.

[0177] It can be understood that the setting of the positioning part 140 further simplifies the entire control system. During control, it is only necessary to control the position of the positioning part 140 to achieve control of the opening of each channel. Each position of the positioning part 140 can be mapped to a different waterway position, so that the overall component does not require a complex control system, reducing the difficulty of preparation.

[0178] According to an embodiment provided by the present application, referring to Figures 8 and 15, the first valve body 300A further includes a mounting portion 320, the mounting portion 320 is connected to the drain channel 310, and a mounting chamber is provided in the mounting portion 320, the first end of the mounting chamber has an opening, and the inner wall of the mounting chamber has a connecting port, and the connecting port is used to connect the mounting chamber with the drain channel 310; the pressure rod assembly 200A includes a pressure rod body 210A, a fixing sleeve 220A and a limiting sleeve 230A, one end of the pressure rod body 210A is connected to the limiting disk 240, and the other end of the pressure rod body 210A is connected to the mating head 2101; the fixing sleeve 220A is fixedly arranged in the mounting chamber with the opening End; the limiting sleeve 230A is connected to the fixed sleeve 220A, and the fixed sleeve 220A and the limiting sleeve 230A are both sleeved on the pressure rod body 210A, and a spring 250 is sleeved between the limiting plate 240 and the fixed sleeve 220A, so that the pressure rod body 210A can be reset under the action of the spring 250; wherein, the side wall inside the limiting sleeve 230A is provided with a connecting port 2301, and the connecting port 2301 is communicated with the connecting port, and the first end of the limiting sleeve 230A away from the fixed sleeve 220A has a mating port 2302, the mating port 2302 is communicated with the connecting port 2301, and the mating port 2302 can be matched and sealed with the mating head 2101. The pressure rod assembly 200A needs to cooperate with the sewage channel 310 to realize the opening of the sewage channel 310. As shown in Figure 12, in this embodiment, a mating head 2101 is provided on the first end of the pressure rod body 210A, and sealing is achieved by the contact and cooperation between the mating head 2101 and the mating port 2302. When the pressure rod body 210A is squeezed, the mating head 2101 and the mating port 2302 are no longer sealed. At this time, the sewage channel 310 can be opened for sewage discharge operations.

[0179] It is understood that, as shown in Figures 11 and 15, when the lever assembly 200A is in normal operation, the lever body 210A, due to the action of the spring 250, causes the mating head 2101 to contact and seal with the mating port 2302 on the limiting sleeve 230A. When the protrusion 130 abuts the lever body 210A, the lever body 210A extends, as shown in Figure 12. At this point, the mating head 2101 and the mating port 2302 no longer contact each other, allowing the drain channel 310 to be opened. The extension and retraction of the lever practice the opening and closing of the drain channel 310, which has a fast response speed and can promptly and quickly achieve the opening and closing of the drain channel 310.

[0180] According to one embodiment provided herein, as shown in Figures 9 and 10 , a lever mechanism 400A is further included. The lever mechanism 400A is disposed between the compression rod assembly 200A and the raised portion 130. The lever mechanism 400A is used to amplify and transmit thrust. The raised portion 130 is disposed on the rotating component 110A, which is connected to the valve core to transmit mechanical energy, thereby enabling the valve core to operate. In this embodiment, the provision of the lever mechanism 400A increases the service life of the valve system and reduces the difficulty and cost of maintenance.

[0181] It is understandable that the connection between the rotating component 110A and the valve core of the second valve body 100A and the direct interaction of the protrusion 130 with the pressure rod assembly 200A can easily damage the protrusion 130, a problem that becomes particularly prominent over extended periods of time. Once the protrusion 130 is damaged, the rotating component 110A must be disassembled, which is difficult and can easily damage the valve core during assembly and disassembly. In this embodiment, by providing a lever mechanism 400A between the protrusion 130 and the pressure rod assembly 200A, the lever mechanism 400A is used to transmit the force, significantly preventing damage to the protrusion 130 and extending its service life. Furthermore, compared to disassembly and maintenance of the rotating component 110A, the lever mechanism 400A is much simpler to disassemble and maintain, resulting in lower maintenance difficulty and costs.

[0182] 14 , the lever mechanism 400A includes a crank lever 410. The first end of the crank lever 410 is rotatably mounted, and the other end of the crank lever 410 is positioned between the rotating component 110A and the lever assembly 200A. The crank transmits force to the protrusion 130 through its own rotation. The rotation of the end of the crank lever 410 amplifies the transmitted force, allowing the protrusion 130 to squeeze the lever assembly 200A with relatively little force, thereby opening the drain channel 310.

[0183] In a specific application, referring to Figure 14, there is a protruding contour on the end face where the crank pressure rod 410 contacts the protrusion 130. The contour can cooperate with the protrusion 130 so that the assembly abuts against the contour during the rotation of the protrusion 130, and finally pushes the pressure rod assembly 200A to open the sewage channel 310.

[0184] It can be understood that, for the sake of compact structure and overall layout, the crank pressure rod 410 is rotatably set on the second valve body 100A, and the crank pressure rod 410 is located on one side of the rotating part 110A, and the entire crank pressure rod 410 is located below the rotating part 110A, so that a part of the crank pressure rod 410 can be located below the rotating part 110A to achieve contact with the protrusion 130.

[0185] In the specific configuration, as shown in Figures 13 and 14 , the crank lever 410 is further configured with a guide slot 4101. The second valve body 100A is provided with a guide post 160, the top of which cooperates with the guide slot 4101 for guidance. The guide post 160 has a certain length and one end is pivotally connected. In this embodiment, the provision of the guide slot 4101 and the guide post 160 enhances the stability of the crank lever 410, thereby making the opening of the entire sewage discharge passage 310 more reliable and stable.

[0186] It can be understood that when in use, the crank pressure rod 410 contacts the protrusion 130 to achieve rotation, which makes it very easy to shake when rotating around one end. In this embodiment, the guide column 160 and the guide groove 4101 are coordinated to allow the guide column 160 to guide during rotation, thereby preventing its shaking and improving the stability of the crank pressure rod 410 rotation.

[0187] In a specific application, as shown in FIG14 , the first end of the crank lever 410, which is adjacent to the lever assembly 200A, has a retaining groove 4102 for contact with the lever assembly 200A. The contacting end of the lever assembly 200A is a rod-like structure, which can wobble when in contact with a flat surface. In this embodiment, the retaining groove 4102 on the crank lever 410 prevents this wobble during contact, improving the stability of the overall structure.

[0188] The present application also provides a water softener, comprising a water channel component 500A, a salt box 700A, and a sewage system as provided in any of the above embodiments, wherein the water channel component 500A and the salt box 700A are both connected to the sewage system.

[0189] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment provides a protrusion 130 on the rotating part, and cooperates with the pressure rod assembly 200A through the protrusion 130, so that the protrusion 130 can realize the squeezing of the pressure rod assembly 200A, thereby realizing the opening of the sewage channel 310. The opening of the entire sewage channel 310 is realized by mechanical transmission. The structure of the entire switch is simple, and the reliability and stability are strong.

[0190] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be encompassed by the claims of the present application.
