In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0043] Hard water has a variety of effects on daily life and household equipment. First, the washing effect will be reduced because the calcium and magnesium ions in hard water react with detergents to form soap scum, causing clothes to become yellow, dusty, and feel bad after washing. Secondly, hard water causes scale to accumulate on water pipes, water heaters and other equipment, resulting in reduced water flow, reduced pressure, and damage to equipment performance and life. In addition, the minerals in hard water are irritating to the skin and hair, which may cause dryness, itching and hair quality problems. At the same time, scale forms a heat conduction barrier on the surface of heating equipment, reducing energy efficiency and increasing energy consumption and costs. Finally, the high mineral content in hard water may be unfavorable to the health of some people, and there is a potential risk of excessive metal ions. Therefore, people use water softeners to treat water quality in daily life. Using water softeners can effectively remove minerals in hard water, improve water quality, and improve the quality of life. Usually, water softeners remove calcium and magnesium ions in water through the process of ion exchange, thereby converting hard water into soft water.

[0044] Among them, water softeners usually use resin for treatment. This resin is a polymer substance with a special structure and a positive charge on its surface. When hard water passes through the ion exchange resin column, the calcium and magnesium ions in it will adsorb to the positive charge on the surface of the resin, replacing the original sodium ions on the resin. During the exchange process, the contact effect between the raw water and the resin will directly affect the softening effect. How to improve the raw water distribution effect will directly affect the final softening efficiency and quality.

[0045] In the related art, the waterway plate is used to connect with the resin barrel, and the waterway plate and the resin barrel are usually set separately, and then the resin barrel and the flow channel part are connected and sealed by assembly. This method requires the resin barrel and the flow channel part to be assembled independently, and assembly errors will inevitably occur during the assembly process. For example, the connection between the resin barrel and the waterway plate is achieved by threading. This method requires the resin barrels to be assembled one by one, and the assembly process is cumbersome. It is usually arranged in a single resin barrel. In order to have better softening performance, a single resin barrel needs a larger volume of resin barrel to load more resin particles. The larger volume of the resin barrel makes the overall space occupied large, and then the overall structural space occupies a large space, which is not conducive to the installation of the overall structure.

[0046] For problems in related technologies, see Figure 1-Figure 3 As shown, the utility model provides a flow channel connection assembly, including a flow channel portion 100 and a resin barrel 200, the flow channel portion 100 has a first flow channel 110 and a second flow channel 120, the first flow channel 110 has a first connection port 1101 for fluid input or fluid output, and the second flow channel 120 has a second connection port 1201 for fluid input or fluid output; the resin barrel 200 has a barrel body 210 and a central tube, the central tube (not shown in the figure) is located in the barrel body 210, and the barrel body 210 is used to fill resin particles; wherein the barrel body 210 and the flow channel portion 100 are integrally formed, the first connection port 1101 is connected to the outer portion of the barrel body 210 through the first flow channel 110, and the second connection port 1201 is connected to the central tube through the second flow channel 120. In this embodiment, the flow channel portion 100 and the resin barrel 200 are integrally formed, and the resin barrel 200 and the flow channel portion 100 can be assembled in an integral manner, thereby reducing the processing and assembly procedures of parts and components, and reducing production costs. It also avoids the risk of assembly errors caused by the connection between the various parts, and improves the reliability of the equipment.

[0047] In this embodiment, the first flow channel 110 and the second flow channel 120 are respectively used for the input or output of liquid fluid, and the input or output is determined by the control valve part connected thereto for control selection. It is understandable that the control valve part needs to meet the softening water path in the softening process, and also needs to meet the regeneration path for the resin particle treatment in the resin barrel 200. For example, when softening, the raw water enters the first flow channel 110 through the first connection port 1101, and is softened by the resin particles in the resin barrel 200. The treated water rises through the central tube and is output from the second connection port 1201 through the second flow channel 120. At this time, the first connection port 1101 is used for the input of fluid, and the second connection port 1201 is used for the output of fluid. During regeneration, brine enters the second flow channel 120 through the second connection port 1201, and enters the bottom of the resin barrel 200 through the central tube. The brine entering the bottom can rise along the outer part of the resin tube to clean the resin particles, and then enters the first flow channel 110 and is output from the first connection port 1101 in the first flow channel 110. At this time, the first connection port 1101 is used for fluid output, and the second connection port 1201 is used for fluid input.

[0048] It can be understood that the present invention realizes the switching of the soft water circuit and the regeneration water circuit through two flow channels, simplifies the structure of the number of flow channels, makes the overall structure simple, and reduces the difficulty of preparation.

[0049] In the specific setting, the flow channel part 100 and the resin barrel 200 are both made of plastic material. Plastic material is easy to shape and is conducive to the construction of the flow channel and the structure 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.

[0050] In one embodiment of the utility model, the flow channel portion 100 and the barrel body portion 210 are integrally formed by an injection molding process. The flow channel in the utility model needs to be constructed and also needs to cooperate with the valve body, which requires it to have good stability and high molding accuracy. Therefore, the injection molding process is used for integral molding, which can achieve high-speed continuous production, high degree of automation, and is conducive to large-scale production. It can also be shaped by a mold, which can make the finished product size more accurate, and can also construct each flow channel more efficiently. In the process of injection molding, the plastic material is melted and formed under high temperature and high pressure, which can ensure that the product has good density, no pores, and no defects, and improve the stability of the product. Moreover, in the process of injection molding, the raw materials can be accurately controlled to reduce waste and waste generation.

[0051] In one embodiment of the utility model, considering that the molded flow channel connection assembly has a flow channel portion 100 and a resin body portion, the two portions need to be in contact with water for a long time, so they need to have good corrosion resistance. Therefore, in this example, the material of the flow channel portion 100 and the barrel body portion 210 is a plastic material with good corrosion resistance, and a preferred embodiment includes glass fiber reinforced polyphenylene ether material. It can be understood that the material for injection molding can also be polypropylene, polyvinyl chloride, polytetrafluoroethylene, etc.

[0052] In this embodiment, considering that in addition to corrosion resistance, it is also necessary to have engineering stability and other factors, glass fiber reinforced polyphenylene ether material is used for injection molding, wherein the glass fiber content in the glass fiber reinforced polyphenylene ether material is between 20% and 60%, and the glass fiber content is configured in a conventional proportion. The glass fiber reinforced polyphenylene ether material itself has high strength and rigidity, which can withstand high pressure during production and use, thereby making the overall stability good, and because the glass fiber reinforced polyphenylene ether material contains glass fiber, the addition of glass fiber can improve the thermal expansion coefficient of polyphenylene ether, so that the composite material has better dimensional stability. Therefore, in this embodiment, by limiting the glass fiber reinforced polyphenylene ether material, the overall structural stability is better, which is conducive to long-term use and improves the service life of the product.

[0053] In one embodiment of the utility model, there are multiple resin barrels 200, and the multiple resin barrels 200 are arranged in parallel and spaced apart along the extension direction of the first flow channel 110 or the extension direction of the second flow channel 120. The resin barrel 200 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, it is usually set as one resin barrel 200, and a resin barrel 200 needs to have a larger volume if it wants to load more resin particles, 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, since the flow channel part 100 and the resin barrel 200 are integrally formed, it can have multiple resin barrels 200. The method of multiple resin barrels 200 can make it narrower in the width direction while having the same volume, which can facilitate the assembly of components.

[0054] When setting up the specific Figure 1 , Figure 2As shown, in this embodiment, there are two resin barrels 200, and the two resin barrels 200 are arranged in parallel. When determining the number of resin barrels 200, the water treatment capacity requirements of the entire waterway plate and the design of the overall structural space occupancy are usually taken into consideration. Therefore, three, four or more resin barrels 200 can be selected in some specific designs. It is understandable that when the resin barrel 200 is added, the flow channel will be arranged in the length direction to achieve the connection between the resin barrel 200 and the flow channel to form a waterway. The drawings in the specification of the embodiments of this application only specifically illustrate the example of two resin barrels 200.

[0055] Reference Figure 6 , Figure 7 As shown, the first flow channel 110 and the second flow channel 120 both extend in a straight horizontal direction, and correspondingly, the resin barrels 200 are arranged in parallel in a horizontal direction. The fluids in the first flow channel 110 and the second flow channel 120 can enter the resin barrel 200 for processing, and then be output or input through the first connection and the second connection port 1201 to realize soft water circuit circulation or regeneration water circuit circulation.

[0056] According to one embodiment of the present invention, see Figure 6 , Figure 7 As shown, there is a spacing space 300 between adjacent barrel parts 210. This facilitates the preparation of the barrel part 210 during integral molding, and during the manufacturing and assembly process of the mold, factors such as the processing accuracy, assembly accuracy, and thermal expansion coefficient of the mold parts need to be considered. The appropriate design of the spacing space 300 can help meet these requirements and ensure the normal operation and life of the mold.

[0057] When setting up the specific Figure 1 , Figure 6-Figure 7 As shown, the top of the barrel body 210 is integrally formed with the flow channel 100, and the bottom of the barrel body 210 has the same end surface integrally formed, that is, the bottom ends of the two barrel bodies 210 are the same end surface. It can be understood that the resin barrel 200 needs to be sealed during use, and the barrel body 210 is easy to shape and seal through the same end surface at the bottom. Figure 2 As shown, a plurality of bolt connection holes are provided on the bottom end surface of the barrel body 210, and a sealing bottom plate is connected to the bottom end surface of the barrel body by bolts. The sealing bottom plate can cooperate with the barrel body 210 to achieve sealing of the whole body, and the connection of the central tube can also be achieved through the bottom end surface of the barrel body 210. That is, when the central tube needs to be connected, the central tube is assembled before the sealing bottom plate is assembled, and the sealing bottom plate is assembled after the central tube is assembled, so that the barrel body 210 is an overall closed space.

[0058] In the specific configuration, at least one connecting rib plate 400 is provided in the partition space 300, and the two ends of the connecting rib plate 400 are respectively connected to the outer wall surfaces of the barrel body 210 on both sides of the partition space 300. The partition space 300 between the barrel body 210 can reduce the overall weight, and in this embodiment, by providing the connecting rib plate 400, a larger connection area can be provided between adjacent barrel body 210, thereby improving the bearing capacity and rigidity of the parts, and enhancing the durability and anti-deformation performance of the parts.

[0059] It can be understood that the connecting ribs 400 are arranged at intervals along the vertical direction of the partition space 300, so that a plurality of connecting ribs 400 can be arranged in the partition space 300. Figure 3 As shown, four connecting ribs 400 are arranged between the two barrel parts 210 in the vertical direction, and the four ribs are arranged equidistantly. Of course, the number of connecting ribs 400 is related to the overall design parameters, and it can be more than four or less than four. The drawings in the specification of the embodiment of this application only specifically illustrate the example of four connecting ribs 400.

[0060] In some specific examples, the connecting rib plate 400 extends from the center of the spacing space 300 to the barrel body portions 210 on both sides, and the two ends of the connecting rib plate 400 are roughly located at the axial center line of the barrel body portion 210. This design can further increase the connection area between the connecting rib plate 400 and the barrel body portions 210 on both sides, and further increase the structural strength of the two barrel body portions 210, thereby improving the load-bearing capacity and rigidity of the parts, and enhancing the durability and anti-deformation performance of the parts.

[0061] In specific applications, the connecting rib plate 400 is integrally formed with the barrel body 210 on both sides, so that the two ends of the connecting rib plate 400 are respectively connected to the barrel body 210 on one side, and the connecting rib plate 400 is made of the same material as the barrel body 210. This makes the connecting rib plate 400 and the barrel body 210 have good consistency, strong connection strength, good overall rigidity and strength, can withstand higher pressure, and the service life of the components is longer.

[0062] According to one embodiment of the utility model, referring to Figure 4 , Figure 7As shown, each first flow channel 110 has a first communication port 1102 corresponding to the barrel body 210, and the first communication port 1102 is used to connect the first flow channel 110 with the resin particle part of the barrel body 210. The barrel body 210 is generally a cylindrical barrel structure, and has a receiving cavity in the barrel body 210, and the receiving cavity is used to fill the resin particles. The first communication port 1102 is clamped on the first flow channel 110, so that the fluid in the first flow channel 110 can enter the barrel body 210 from the first flow channel 110, and the raw water entering the barrel body 210 is in contact with the resin particles, thereby realizing the treatment of ions in the water quality.

[0063] In the specific setting, the first connecting port 1102 is opened along the extension direction of the first flow channel 110, and the first connecting port 1102 is located as a whole in the barrel body 210. The opening along the extension direction of the first flow channel 110 can increase the opening size of the first connecting port 1102, and can make the diameter of the first connecting port 1102 larger than the inner diameter of the first flow channel 110, so that the first connecting port 1102 has a better water distribution capacity. The better water distribution capacity can make the raw water fully contact with the resin particles during the softening process, thereby improving the quality of water treatment.

[0064] In a specific application, the size of the first communication port 1102 along the first flow channel 110 should be between 20 mm and 50 mm, and the corresponding diameter cross-sectional area of ​​the first communication port 1102 is larger than the longitudinal cross-sectional area of ​​the first flow channel 110. In a specific example, the size of the first communication port 1102 on the first flow channel 110 is 41.05 mm.

[0065] According to an embodiment of the present invention, each second flow channel 120 has a second communication port 1202 corresponding to the resin barrel 200, and the second communication port 1202 is used to communicate with the central tube. It can be understood that the outer portion of the central tube has resin particles. When performing soft water operation, the raw water needs to be processed by the resin particles and then output through the central tube, that is, each second communication port 1202 is connected to the corresponding central tube, which allows the treated water in each resin barrel 200 to enter the second flow channel 120 at the same time, thereby improving the efficiency of water treatment.

[0066] When setting up the specific Figure 4 , Figure 6 As shown, the central tube is arranged at the central position of the barrel portion, and therefore, the second connecting port 1202 is opened at the central position of the barrel body 210. In order to open the second connecting port 1202, an outward convex structure is provided on the second flow channel 120. The outward convex structure extends from the outer wall of the second flow channel 120 to the center of the barrel body 210, and the second connecting port 1202 is processed at the bottom of the extended end of the outward convex structure, and the connection with the central tube is achieved through the second connecting port 1202.

[0067] In some specific embodiments, there is a certain angle between the outer convex structure and the second flow channel 120, and when there are two barrels, refer to Figure 4 As shown, the convex structures in the two barrel bodies 210 are arranged in parallel and extend to the center of the barrel body 210, so that holes can be opened at the bottom of the convex structures to achieve mutual communication between the second connecting port 1202 and the central tube and the second flow channel 120.

[0068] In specific applications, such as Figure 5-Figure 7 As shown, the first connection port 1101 is located between the two first connection ports 1102, and the second connection port 1201 is located between the two second connection ports 1202. The first connection port 1101 and the second connection port 1201 can realize the input of fluid or the output of fluid. For example, when soft water treatment is performed, raw water is input through the first connection port 1101, and the input raw water enters the first connection ports 1102 on both sides through diversion and contacts with the corresponding resin filling parts for treatment. The diversion method can facilitate the full contact between the water body and the resin particles to improve the quality of water treatment. When the resin particles are regenerated, since the first connection port 1102 is connected in parallel with the first flow channel 110, and the second connection port 1202 is connected in parallel with the second flow channel 120, this can slow down the salt absorption flow rate, and the low flow rate salt water can fully contact with the resin particles, which is conducive to the regeneration of the resin and improves the efficiency of the resin regeneration.

[0069] In the specific setting, the first flow channel 110 and the second flow channel 120 are arranged side by side in parallel, and the first flow channel 110 and the second flow channel 120 are respectively located on both sides of the longitudinal section where the center of the barrel body 210 is located. By arranging the two flow channels side by side, more uniform plastic filling and solidification can be achieved. The two flow channels arranged side by side can simultaneously inject molten plastic into the mold cavity, so that the plastic is more evenly distributed in the mold cavity, reducing the problem of insufficient filling or uneven filling, thereby improving the overall quality of the flow channel part 100. And by arranging the first flow channel 110 and the second flow channel 120 on both sides of the barrel body 210 respectively, the overall component layout can be made more compact, and the space occupied by the flow channel part 100 in the width direction can be effectively shortened.

[0070] According to one embodiment of the utility model, the maximum distance between the first flow channel 110 and the second flow channel 120 is less than or equal to the diameter of the outer portion of the barrel body 210. The outer diameter of the barrel body 210 is the diameter of the outer edge of the barrel body 210, and the distance between the first flow channel 110 and the second flow channel 120 is less than the diameter of the outer edge of the barrel body 210. Since part of the flow channel wall of at least one of the first flow channel 110 and the second flow channel 120 is located inside the barrel body 210, the first flow channel 110 opens the first communication port 1102 in the part located inside the barrel body 210, and the second flow channel 120 opens the second communication port 1202 through the outer convex structure.

[0071] In the specific arrangement, in order to further make the layout more compact and reduce the overall space occupied in the width direction, the first connection port 1101 and the second connection port 1201 are symmetrically arranged in the longitudinal section where the center of the barrel body 210 is located. This ensures that the first flow channel 110 and the second flow channel 120 will not exceed the outer edge diameter of the barrel body 210, that is, the first flow channel 110 and the second flow channel 120 are both located inside the barrel body 210.

[0072] In specific applications, such as Figure 5 As shown, there are two resin barrels 200, which are located below the flow channel portion 100. The two resin barrels 200 can make this embodiment narrower in the width direction with the same resin particle capacity.
