[0044] Hard water has a variety of impacts on daily life and household appliances. First, washing performance is reduced because the calcium and magnesium ions in hard water react with detergents to form soap scum, which causes clothes to yellow, pick up dust, and feel unpleasant after washing. Second, hard water can cause scale to accumulate on pipes, water heaters, and other equipment, reducing water flow and pressure, and damaging equipment performance and lifespan. Furthermore, the minerals in hard water are irritating to the skin and hair, potentially causing dryness, itching, and hair problems. Furthermore, scale forms a barrier to heat conduction on heating equipment, reducing energy efficiency and increasing energy consumption and costs. Finally, the high mineral content in hard water can be detrimental to the health of some people and poses a potential risk of excessive metal ion levels. Therefore, people use water softeners to treat their water. Using a water softener can effectively remove minerals from hard water, improve water quality, and enhance their quality of life. Water softeners typically use an ion exchange process to remove calcium and magnesium ions from water, converting hard water into soft water.

[0045] Water softeners typically use resin, 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 water react with the positive charges on the resin surface, replacing the sodium ions already present. The contact between the raw water and the resin during this exchange process directly affects the softening effect. Improving raw water distribution directly impacts the ultimate softening efficiency and quality.

[0046] 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. The resin barrel and the flow channel part are then connected and sealed by assembly. This method requires the resin barrel and the flow channel part to be assembled independently, and assembly errors are inevitable 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. A single resin barrel is usually arranged. In order to have better softening performance, a single resin barrel needs to have a larger volume to hold more resin particles. The larger volume of the resin barrel makes the overall space occupied larger, and thus the overall structural space occupied larger, which is not conducive to the installation of the overall structure.

[0047] For related technical issues, see Figure 1-Figure 3 As shown, the present invention 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 part 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 runner section 100 and the resin barrel 200 are integrally formed. This integral molding eliminates the need for assembly of the resin barrel 200 and the runner section 100, reduces component processing and assembly steps, and lowers production costs. It also avoids the risk of assembly errors caused by the connections between components, improving device reliability.

[0048] In this embodiment, the first flow channel 110 and the second flow channel 120 are respectively used for the input or output of liquid fluids, and the input or output is determined by the control valve portion connected thereto. It is understandable that the control valve portion needs to meet the requirements of the softening water path during the softening process and the regeneration path for the resin particles in the resin barrel 200. For example, during softening, 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 fluid input, and the second connection port 1201 is used for fluid output. During regeneration, brine enters the second flow channel 120 through the second connecting 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 connecting port 1101 in the first flow channel 110. At this time, the first connecting port 1101 is used for fluid output, and the second connecting port 1201 is used for fluid input.

[0049] It can be understood that the present invention realizes the switching between the soft water channel and the regeneration water channel through two flow channels, simplifies the structure of the number of flow channels, makes the overall structure simple, and reduces the difficulty of preparation.

[0050] 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 mold 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.

[0051] In one embodiment of the present invention, the flow channel portion 100 and the barrel portion 210 are integrally formed through an injection molding process. The flow channel in the present invention 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, a high degree of automation, and is conducive to large-scale production. It can also be shaped using molds, which can make the finished product size more accurate and can also construct each flow channel more efficiently. In the injection molding process itself, the plastic material is melted and molded under high temperature and high pressure, which can ensure that the product has good density, no pores, and no defects, thereby improving the stability of the product. Furthermore, in the injection molding process, the raw materials can be precisely controlled to reduce waste and waste generation.

[0052] In one embodiment of the present invention, the molded flow channel connection assembly comprises a flow channel portion 100 and a resin body portion, both of which are in contact with water for a long time and therefore require good corrosion resistance. Therefore, in this embodiment, the flow channel portion 100 and the barrel portion 210 are made of a plastic material with good corrosion resistance. In a preferred embodiment, a glass fiber reinforced polyphenylene ether material is included. It is understood that the injection molding material may also be polypropylene, polyvinyl chloride, polytetrafluoroethylene, etc.

[0053] In this embodiment, considering that in addition to corrosion resistance, engineering stability and other factors are also required, 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 both in production and during 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.

[0054] In one embodiment of the present invention, 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 fill resin, and the amount of resin filled 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 barrel 200, and a resin barrel 200 needs to have a larger volume if it wants to fill 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 is possible to have multiple resin barrels 200. The multiple resin barrels 200 can make it narrower in the width direction while having the same volume, which can facilitate the assembly of components.

[0055] 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 barrels 200 are added, the flow channel will be arranged in the length direction to achieve the connection between the resin barrels 200 and the flow channel to form a water channel. The drawings in the embodiment specification of this application only specifically illustrate the example of two resin barrels 200.

[0056] 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. Correspondingly, the resin barrels 200 are arranged side by side in a horizontal straight 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 circulation or regeneration water circulation.

[0057] According to one embodiment of the present invention, see Figure 6 、 Figure 7 As shown, there is a spacing space 300 between adjacent barrel bodies 210. This facilitates the preparation of the barrel body 210 during integral molding. During the manufacturing and assembly of the mold, factors such as the processing accuracy of the mold parts, assembly accuracy, and thermal expansion coefficient of the material 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.

[0058] 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 portion 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 is understandable that the resin barrel 200 needs to be sealed during use, and the barrel body 210 is convenient for molding and sealing connection through the same end surface at the bottom. For example, referring to 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 a full body seal, and can also achieve connection of the central tube through the bottom end surface of the barrel body 210. That is, when it is necessary to connect the central tube, 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 entirely enclosed space.

[0059] In a specific configuration, at least one connecting rib 400 is provided within the partition 300, with both ends of the connecting rib 400 connected to the outer wall surfaces of the barrel body 210 on either side of the partition 300. The partition 300 between the barrel body 210 can reduce the overall weight. In this embodiment, the provision of the connecting rib 400 allows for a larger connection area between adjacent barrel body 210, thereby improving the load-bearing capacity and rigidity of the component, and enhancing the durability and deformation resistance of the component.

[0060] It can be understood that the connecting ribs 400 are spaced apart in 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 provided vertically between the two barrel portions 210, and the four ribs are equidistantly spaced. Of course, the number of connecting ribs 400 is related to the overall design parameters, and it can be more or less than four. The drawings in the present embodiment of the present application only illustrate an example of four connecting ribs 400.

[0061] In some specific examples, the connecting ribs 400 extend from the center of the separation space 300 to the barrel body portions 210 on both sides, and the two ends of the connecting ribs 400 are roughly located at the axial centerline of the barrel body portion 210. This design can further increase the connection area between the connecting ribs 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.

[0062] In practical applications, the connecting ribs 400 are integrally formed with the barrel body 210 on both sides, so that both ends of the connecting ribs 400 are connected to the barrel body 210 on one side, and the connecting ribs 400 are made of the same material as the barrel body 210. This ensures good consistency between the connecting ribs 400 and the barrel body 210, and can provide strong connection strength, good overall rigidity and strength, can withstand higher pressure, and extend the service life of the components.

[0063] According to one embodiment of the present invention, referring to Figure 4 、 Figure 7As shown, each first flow channel 110 has a first communication port 1102 corresponding to the barrel body 210. The first communication port 1102 is used to connect the first flow channel 110 with the resin particle portion of the barrel body 210. The barrel body 210 is generally a cylindrical barrel structure, with a receiving cavity inside the barrel body 210, which is used to fill the resin particles. The first communication port 1102 is fixed on the first flow channel 110, so that the fluid in the first flow channel 110 can enter the barrel body 210 through the first flow channel 110. The raw water entering the barrel body 210 comes into contact with the resin particles, thereby achieving ion treatment in the water.

[0064] In the specific setting, the first connecting port 1102 is opened along the extension direction of the first flow channel 110, and the entire first connecting port 1102 is located inside 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 better water distribution capacity. Through the better water distribution capacity, the raw water can fully contact with the resin particles during the softening process, thereby improving the quality of water treatment.

[0065] In a specific application, the size of the first communication opening 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 opening 1102 should be larger than the longitudinal cross-sectional area of ​​the first flow channel 110. In a specific example, the size of the first communication opening 1102 along the first flow channel 110 is selected to be 41.05 mm.

[0066] According to one embodiment of the present invention, each second flow channel 120 has a second communication port 1202 corresponding one-to-one with a resin barrel 200. The second communication port 1202 is used to communicate with the central tube. It is understood that the peripheral portion of the central tube contains resin particles. During water softening operations, raw water is processed by the resin particles before being output through the central tube. In other words, each second communication port 1202 is connected to the corresponding central tube. This allows the treated water in each resin barrel 200 to enter the second flow channel 120 simultaneously, improving water treatment efficiency.

[0067] When setting up the specific Figure 4 、 Figure 6 As shown, the central tube is arranged at the center of the barrel portion, and therefore, the second connecting port 1202 is opened at the center 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.

[0068] 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.

[0069] 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 or output of fluid. For example, when performing soft water treatment, raw water is input through the first connection port 1101. The input raw water enters the first connection ports 1102 on both sides through diversion and contacts the corresponding resin filling parts for treatment. The diversion method can facilitate sufficient contact between the water and the resin particles, thereby improving the quality of water treatment. When regenerating resin particles, 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 salt water can fully contact the resin particles, which is beneficial to the regeneration of the resin and improves the efficiency of resin regeneration.

[0070] In the specific setting, the first runner 110 and the second runner 120 are arranged side by side in parallel, and the first runner 110 and the second runner 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 runners side by side, more uniform plastic filling and solidification can be achieved. The two runners 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 runner part 100. And by arranging the first runner 110 and the second runner 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 runner part 100 in the width direction can be effectively shortened.

[0071] According to one embodiment of the present invention, 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. 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 is provided with a first communication port 1102 in the portion located inside the barrel body 210, and the second flow channel 120 is provided with a second communication port 1202 through an external protruding structure.

[0072] 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 of the center of the barrel body 210. This ensures that the first flow channel 110 and the second flow channel 120 do 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.

[0073] In specific applications, such as Figure 5 As shown, two resin barrels 200 are provided, located below the runner portion 100. These two resin barrels 200 enable this embodiment to be narrower in the width direction while maintaining the same resin particle capacity. Furthermore, by arranging the first runner 110 and the second runner 120 within the two resin barrels 200, with portions of the first runner 110 and the second runner 120 spanning the two resin barrels 200, the overall width space occupied by the component is further reduced.
