Description

TECHNICAL FIELD

[0002] The soft water purifier is a device for removing calcium ions, magnesium ions and other ions in water by using cation exchange resin to reduce the hardness of raw water, thereby achieving the effect of softening hard water. The resin tank is currently made of glass steel material wrapped in plastic. Due to the winding forming process, the upper and lower ends need to be designed with a necking method to ensure the strength requirement. At the same time, due to the strength reason, a circular cross section is uniformly adopted. However, the soft water purifier usually adopts a single resin tank design, and the cross section is circular. The cabinet of the soft water purifier is usually square in design, so there is a large space waste in the four corners of the cabinet, which seriously limits the horizontal size of the soft water purifier due to the size of the resin tank.

[0053] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0054] In related technologies, distributing the resin core of the resin tank into multiple resin chambers can, to some extent, solve the problem of the large size of the water purifier caused by the resin tank. However, this also increases the difficulty of designing the flow path for the multiple resin chambers. For example, when fluids share the same channel to enter and exit multiple resin chambers, placing the channel in the central area of ​​the multiple resin chambers can make the flow path lengths of the fluids entering and exiting the multiple resin chambers similar, thus achieving a stable flow rate. However, placing the channel in the central area of ​​the multiple resin chambers will occupy space, making it difficult to use the space at the end of the resin tank for installing other components of the water purifier. On the other hand, if the channel is placed away from the central area of ​​the multiple resin chambers, although it can meet the space utilization requirements and allow the space at the end of the resin tank to be used for installing other components of the water purifier, it can easily lead to different flow paths for the fluids entering and exiting the multiple resin chambers, making it difficult to control the flow rate stability of the fluids entering and exiting the multiple resin chambers. Based on the above problems, this application provides a water purifier that improves the structure of the resin tank.

[0055] like Figure 1 As shown, this is an embodiment of a water purifier / softener 001 provided in this application. The water purifier / softener 001 includes a housing assembly and a water softening system disposed within the internal space of the housing assembly, such as... Figure 2 and Figure 3 As shown, the soft water system 002 includes a resin tank 010, which includes a tank body 0120. The tank body 0120 includes an outer cylinder 012 and two plugs 013, which are respectively installed on the outer cylinder 012. Figure 4 As shown, one of the plugs 013 and the outer cylinder 012 enclose a first resin chamber 012h, and the other plug 013 and the outer cylinder 012 enclose a second resin chamber 012k. The resin tank 010 also includes two resin cores, one of which is located in the first resin chamber 012h, and the other is located in the second resin chamber 012k. The resin cores can remove calcium, magnesium, and other ions from hard water, converting the raw water into soft water.

[0056] In this embodiment, the first resin cavity 012h and the second resin cavity 012k of the tank body 0120 are arranged side by side along the first direction X. In this way, the two resin cores are placed in two different cavities. While satisfying the same resin volume, the size of the resin tank 010 in the second direction Y can be reduced. The second direction Y is perpendicular to the first direction X, so that space is reserved in the second direction Y for installing other structures of the water purifier 001, thereby reducing the size of the water purifier 001 in the second direction Y.

[0057] like Figure 2As shown, the water purifier / softener 001 also includes a water purification system 003. The water softening system 002 and the water purification system 003 are arranged side-by-side in the second direction Y. The water purification system 003 is connected to the water softening system 002 to receive the soft water supplied by the water softening system 002 and purify the soft water to generate pure water. By arranging the first resin chamber 012h and the second resin chamber 012k of the tank body 0120 side-by-side in the first direction X, the water softening system 002 has a rectangular outer contour with a larger dimension in the first direction X and a smaller dimension in the second direction Y. This makes the arrangement of the water purification system 003 and the water softening system 002 in the second direction Y more compact, reducing the size of the water purifier / softener 001 in the second direction Y.

[0058] The outer cylinder 012 also has a first channel 012x, which has a connecting port 012c for fluid to enter and exit the first channel 012x. The connecting port 012c is set corresponding to the first resin cavity 012h. The first channel 012x includes a first section 012a and a second section 012b respectively disposed on opposite sides of the connecting port 012c in the first direction X. The first section 012a is connected to the first resin cavity 012h, and the second section 012b is connected to the second resin cavity 012k. The fluid in the first resin cavity 012h and the second resin cavity 012k can flow out of the first channel 012x after converging at the connecting port 012c through the first channel 012x. The fluid can also be diverted at the connecting port 012c to the first section 012a and the second section 012b and then enter the first resin cavity 012h and the second resin cavity 012k respectively.

[0059] When the interface 012c is set to correspond to the first resin chamber 012h, the space on the same side (away from the plug 013) of the first resin chamber 012h and the second resin chamber 012k is larger than that of the second resin chamber 012k. Therefore, other structural components of the water purifier 001 can be installed using the space on one side of the second resin chamber 012k. For example, the water softening system 002 also includes a water softening valve 020, so the space on one side of the second resin chamber 012k can be used to install the water softening valve 020.

[0060] In this embodiment, the flow area of ​​the first segment 012a is larger than that of the second segment 012b. This allows for a further reduction in the volume of the portion of the outer cylinder 012 containing the second segment 012b, reserving space for installing other structural components of the water purifier 001, thereby further reducing the overall volume of the water purifier 001. In this embodiment, all "flow area" refers to the cross-sectional area of ​​the corresponding channel along the direction of fluid flow.

[0061] like Figure 3 and Figure 4As shown, the tank body 0120 includes multiple main pipes 0121. Each main pipe 0121 has a first channel 012x inside. The interface 012c of the first channel 012x is set corresponding to the first resin cavity 012h. The outer surface of the portion of the main pipe 0121 corresponding to the second resin cavity 012k includes a support plane 012f, which is used to support the soft water valve 020. By arranging the first resin cavity 012h and the second resin cavity 012k side by side along the first direction X, and setting the interface 012c corresponding to the first resin cavity 012h, the space on the same side of the first resin cavity 012h and the second resin cavity 012k can be used to install the soft water valve 020, and the soft water valve 020 can have a larger bearing area in the first direction X. This not only reduces the size of the soft water system 002 in the first direction X, but also improves the installation stability of the soft water valve 020, making the overall structure of the soft water system 002 compact, the appearance neat, and the installation of the soft water system 002 convenient.

[0062] Each main pipe 0121 extends along the first direction X, and multiple main pipes 0121 are arranged side by side along a second direction Y perpendicular to the first direction X. The support planes 012f of the multiple main pipes 0121 are used to support the soft water valve 020. By providing support for the soft water valve 020 in multiple spaced areas through multiple main pipes 0121, the support stability of the resin tank 010 for the soft water valve 020 is further improved. Based on the installation requirements of the soft water valve 020, the multiple support planes 012f can be located on the same plane, or the multiple support planes 012f can be located on multiple parallel and non-coplanar planes, so as to flexibly design the position and shape of the support planes 012f according to the structure of the soft water valve 020.

[0063] The outer surface of the portion of the main pipe 0121 with the second segment 012b includes a supporting plane 012f, which facilitates the design of the structure of the portion of the main pipe 0121 with the second segment 012b, so that the main pipe 0121 has a supporting plane 012f, and at the same time can meet the design requirement that the flow area of ​​the first segment 012a is greater than the flow area of ​​the second segment 012b, and facilitates the molding of the main pipe 0121.

[0064] It is understandable that the flow area of ​​the first segment 012a is set to be larger than that of the second segment 012b. Although the size of the portion of the outer cylinder 012 corresponding to the first segment 012a is larger, the larger flow area of ​​the first segment 012a facilitates demolding of the mold at the first segment 012a, thus facilitating the processing of the outer cylinder 012, since there is no need for space reduction at the first segment 012a. However, since the flow areas of the first segment 012a and the second segment 012b are different, it is easy for the flow rate of the fluid entering the first segment 012a to be different from that entering the second segment 012b. Therefore, in this embodiment, the resin tank 010 also includes a first plug 015, which adjusts the flow area of ​​the fluid in the first segment 012a.

[0065] like Figure 5 As shown, the first plug 015 includes a sealing part 0151 and an adjusting part 0152. The sealing part 0151 seals the end of the first segment 012a away from the second segment 012b, preventing the fluid in the first segment 012a from flowing out. It is understandable that, due to the configuration of the interface 012c corresponding to the first resin cavity 012h, the flow rate between the interface 012c and the first resin cavity 012h is likely to be less than the flow rate between the interface 012c and the second resin cavity 012k. When the flow area of ​​the first segment 012a is relatively large, the flow rate of the fluid in the first segment 012a is likely to be large. Furthermore, the lower the flow rate of the fluid at the interface 012c, the greater the difference in flow rate between the first segment 012a and the second segment 012b. Based on this, the first plug 015 in this embodiment of the application also includes an adjustment part 0152. The adjustment part 0152 is disposed in the first section 012a so that the flow area of ​​the flow channel enclosed by the surface of the adjustment part 0152 and the wall of the first section 012a is less than or equal to the flow area of ​​the second section 012b, so as to reduce the flow rate difference of the fluid in the first section 012a and the second section 012b.

[0066] like Figure 5 As shown, the first resin cavity 012h has a first central axis S1, and the second resin cavity 012k has a second central axis S2. The first central axis S1 and the second central axis S2 are parallel. The perpendicular line connecting the first central axis S1 and the second central axis S2 has a preset midpoint. Along the first direction X, the interface 012c is located between the preset midpoint and the first central axis S1, offsetting the interface 012c relative to the first resin cavity 012h and the second resin cavity 012k. At the same time, it is also convenient to adjust the first flow between the interface 012c and the first resin cavity 012h, and the second flow between the interface 012c and the second resin cavity 012k to be close to or equal.

[0067] In this embodiment, the first resin cavity 012h and the corresponding resin core are coaxially arranged, and the second resin cavity 012k and the corresponding resin core are coaxially arranged. That is, the first central axis S1 is collinear with the central axis of the resin core in the first resin cavity 012h, and the second central axis S2 is collinear with the central axis of the resin core in the second resin cavity 012k. The resin core rests against the plug 013. The first resin cavity 012h has a first top wall surface away from the corresponding plug 013, and the second resin cavity 012k has a second top wall surface away from the corresponding plug 013. In the direction parallel to the first central axis S1, the outer contour of the cross-section of the resin core is circular. Correspondingly, the outer contour of the cross-section of the first resin cavity 012h is circular, and the outer contour of the cross-section of the second resin cavity 012k is circular.

[0068] Considering the processing requirements, the edge areas of the first top wall and the edge areas of the second top wall are arc-shaped. Usually, the area where the first resin cavity 012h and the first segment 012a are connected is located in the central area of ​​the first top wall, and the area where the second resin cavity 012k and the second segment 012b are connected is located in the central area of ​​the second top wall. However, since the interface 012c is located between the preset midpoint and the first central axis S1, and it is also necessary to consider that the first flow between the interface 012c and the first resin cavity 012h and the second flow between the interface 012c and the second resin cavity 012k are close to or equal, it is also necessary to design the areas where the first resin cavity 012h and the first segment 012a are connected and the areas where the second resin cavity 012k and the second segment 012b are connected separately.

[0069] In some embodiments, such as Figure 5 As shown, the first segment 012a has a first opening 012d communicating with the first resin cavity 012h. The first opening 012d has a first opening centerline S3. In the first direction X, the first opening centerline S3 is located on the side of the first central axis S1 away from the second resin cavity 012k, so that by stretching the flow between the interface 012c and the first resin cavity 012h, the first flow between the interface 012c and the first resin cavity 012h and the second flow between the interface 012c and the second resin cavity 012k are close to or equal.

[0070] In some embodiments, the second segment 012b has a second opening 012e communicating with the second resin cavity 012k. The second opening 012e has a second opening centerline S4. In the first direction X, the second opening centerline S4 is located on the side of the second central axis S2 facing the first resin cavity 012h, so as to shorten the flow between the interface 012c and the second resin cavity 012k separately, so that the first flow between the interface 012c and the first resin cavity 012h and the second flow between the interface 012c and the second resin cavity 012k are close to or equal.

[0071] In some embodiments, in the first direction X, the first opening centerline S3 is located on the side of the first central axis S1 away from the second resin cavity 012k, and the second opening centerline S4 is located on the side of the second central axis S2 toward the first resin cavity 012h. By offsetting the interface 012c, the first opening 012d, and the second opening 012e toward the same side, the first flow between the interface 012c and the first resin cavity 012h and the second flow between the interface 012c and the second resin cavity 012k are made to be close to or equal.

[0072] Of course, to meet the processing requirements of the outer cylinder 012, the distances of the first opening 012d from the first central axis S1 and the distances of the second opening 012e from the second central axis S2 should not be too large. In some embodiments, the first opening 012d and the second opening 012e are both circular openings, with the radius of the first opening 012d being R1 and the radius of the second opening 012e being R2. Along the first direction X, the distance between the center line S3 of the first opening and the first central axis S1 is m1, and the distance between the center line S4 of the second opening and the second central axis S2 is m2, where 0 < m1 / R1 ≤ 0.25 and 0 < m2 / R2 ≤ 0.25. Within the above distance range, both the processing requirements of the outer cylinder 012 and the process requirements from the first resin cavity 012h and the second resin cavity 012k to the interface 012c can be met.

[0073] like Figure 5 and Figure 6 As shown, the adjustment part 0152 is disposed in the first section 012a. The adjustment part 0152 includes a first surface 015a facing away from the first resin cavity 012h. The first surface 015a is in contact with the wall of the can body 0120 that defines the first section 012a. The adjustment part 0152 also includes a second surface 015b facing the first resin cavity 012h. The second surface 015b is spaced apart from the wall of the can body 0120 that defines the first section 012a. The fluid entering the first section 012a flows in the channel enclosed by the second surface 015b and the wall of the first section 012a. The flow area of ​​the channel enclosed by the second surface 015b and the wall of the first section 012a can be adjusted by adjusting the shape of the second surface 015b, thereby satisfying the requirement that the flow area of ​​the flow channel enclosed by the surface of the adjustment part 0152 and the wall of the first section 012a is less than or equal to the flow area of ​​the second section 012b.

[0074] The first resin cavity 012h is axially arranged along the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In some embodiments, when the axial direction of the first resin cavity 012h is parallel to the axial direction of the second resin cavity 012k, the distance between the second surface 015b and the first resin cavity 012h along the axial direction of the first resin cavity 012h is L1, and the size of the second segment 012b is L2, where L1≤L2. This can also satisfy the requirement that the flow area of ​​the flow channel enclosed by the surface of the adjustment part 0152 and the wall of the first segment 012a is less than or equal to the flow area of ​​the second segment 012b.

[0075] In some embodiments, the cross-section of the flow channel enclosed by the second surface 015b and the wall of the first segment 012a is similar in shape to the cross-section of the second segment 012b, which helps to reduce the flow resistance of the fluid in the first segment 012a and the second segment 012b, thereby helping to improve the equal flow rates of the fluid in the first segment 012a and the second segment 012b.

[0076] In some embodiments, the second surface 015b is a plane perpendicular to the axial direction of the first resin cavity 012h. The outer cylinder 012 defines the wall surface of the second segment 012b, which includes a preset plane 012e. The preset plane 012e is spaced apart from the second resin cavity 012k along its axial direction, and the preset plane 012e is a plane perpendicular to the axial direction of the second resin cavity 012k. When the axial direction of the first resin cavity 012h is parallel to the axial direction of the second resin cavity 012k, and the outer contour of the cross-section of the first segment 012a along its internal fluid flow direction is circular, the control part is disposed in the first segment 012a, and the second surface 015b is parallel to the preset plane 012e, thereby making the cross-section of the flow channel enclosed by the second surface 015b and the wall surface of the first segment 012a similar in shape to the cross-section of the second segment 012b. At this time, L1 is the distance between the second surface 015b and the first resin cavity 012h in the axial direction, and L2 is the distance between the preset plane 012e and the second resin cavity 012k in the axial direction of the first resin cavity 012h.

[0077] like Figure 7 As shown, along the axial direction of the first resin cavity 012h, the size of the adjusting part 0152 is A, where A satisfies: 3mm ≤ A ≤ 6mm. Within this size range, the adjusting part 0152 can regulate the flow rate of the fluid in the first section 012a. The size A of the adjusting part 0152 is also the size of the outer cylinder 012 in the axial direction of the second resin cavity 012k, which can be reduced by adjusting the shape of the cross-section of the second section 012b. This allows space to be reserved for installing other structural components on the outside of the second resin cavity 012k, thereby helping to reduce the size of the water purifier / softener 001.

[0078] In some embodiments, along the first direction X, the distance between the adjusting part 0152 and the docking interface 012c is B, where B satisfies: 0mm≤B≤1mm. Within this distance range, the fluid can flow smoothly at the connection between the first segment 012a and the docking interface 012c, preventing the excessive distance between the adjusting part 0152 and the docking interface 012c in the first direction X from interfering with the stability of the fluid flow.

[0079] In some embodiments, the dimension of the adjusting part 0152 along the first direction X is C, where C satisfies: 10mm ≤ C ≤ 60mm. Within this dimension range, the length of the adjusting part 0152 is suitable, facilitating the provision of adequate space within the first segment 012a for fluid flow. Furthermore, in addition to facilitating the demolding and molding of the first segment 012a, it also facilitates the adjustment of the length ratio between the sealing part 0151 and the adjusting part 0152 in the first direction X, ensuring that the sealing part 0151 is inserted to a suitable depth into the first segment 012a. The sealing part 0151 effectively seals the end of the first segment 012a furthest from the second segment 012b, and exhibits good installation stability, preventing loosening under the squeezing force of the fluid within the first segment 012a.

[0080] In this embodiment, when processing the outer cylinder 012, the mold is demolded along the direction from the second segment 012b toward the first segment 012a to form the first segment 012a. It is understood that when the cross-sectional shape of the channel is circular, the mold is easier to demold. In this embodiment, there is no need for installation of other structural components in the space outside the first segment 012a. Therefore, the cross-sectional shape of the first segment 012a is set to be circular along the first direction X to facilitate demolding. A portion of the sealing part 0151 is inserted into the first segment 012a and seals the end of the first segment 012a away from the second segment 012b. The outer contour of the sealing part 0151 is also circular and coaxial with the first segment 012a to ensure good sealing stability. The outer surface of the sealing part 0151 smoothly transitions to the first surface 015a of the adjusting part 0152, that is, the first surface 015a is an arc surface and fits against the wall surface of the outer cylinder 012 that defines the first segment 012a.

[0081] In some embodiments, the can body 0120 defines the wall surface of the second segment 012b as including a preset plane 012e, which is parallel to the first direction X and perpendicular to the axial direction of the second resin cavity 012k (perpendicular to the second central axis S2). Thus, along the flow direction of the fluid within the second segment 012b, the outer contour of the cross-section of the second segment 012b is non-circular (i.e., a shape formed by connecting a straight line and an arc with a central angle greater than 180°), which increases the difficulty of demolding the second segment 012b from the mold. Figure 7As shown, the end of the second segment 012b furthest from the first segment 012a is open, so that during demolding, the mold can move along the direction from the first segment 012a toward the second segment 012b, thereby forming the second segment 012b and reducing the demolding difficulty at the second segment 012b. At this time, the resin tank 010 also includes a second plug 016, which seals the end of the second segment 012b furthest from the first segment 012a. The second plug 016 is inserted into the second segment 012b, and the outer surface of the portion of the second plug 016 inserted into the second segment 012b is in contact with the wall of the second segment 012b to improve the sealing stability of the second plug 016.

[0082] It is understandable that, since the interface 012c is located between the preset midpoint and the first central axis S1, the flow between the interface 012c and the second resin cavity 012k is likely to be relatively long. In this embodiment, the depth of the second plug 016 inserted into the second segment 012b is further designed. The second segment 012b has a second opening 012e that communicates with the second resin cavity 012k. Along the first direction X, the distance between the second opening 012e and the second plug 016 is D, where D satisfies: 0mm≤D≤3mm. Within this distance range, the depth of the second plug 016 inserted into the second segment 012b is prevented from being too long or too short, so that the flow of fluid in the second segment 012b is appropriate, so as to regulate the flow rate of fluid in the first segment 012a and the second segment 012b to be close.

[0083] like Figure 7 As shown, the tank body 0120 also has a second channel 012g, which is connected to the first channel 012x at the interface 012c. The second channel 012g extends along the axial direction of the first resin cavity 012h (the direction where the first central axis S1 is located) to guide fluid to enter and exit the first channel 012x along the axial direction of the first resin cavity 012h. When the outer cylinder 012 has multiple first channels 012x, it is convenient to set multiple second channels 012g that are connected to the multiple first channels 012x one by one on the same side of the multiple first channels 012x, so that the second channel 012g can be connected to other structural components of the water purifier 001.

[0084] In some embodiments, the tank body 0120 has two first channels 012x, each extending along a first direction X, and the two first channels 012x are arranged side by side along a second direction Y perpendicular to the first direction X. In the second direction Y, the two first channels 012x are located on opposite sides of the first central axis S1. When the resin tank 010 is used to treat raw water and convert it into soft water, one of the two first channels 012x is an input channel, which is connected to a hard water source and used to input hard water into the first resin chamber 012h. The other of the two first channels 012x is an output channel, which is connected to other flow paths of the water purifier / softener 001 and used to output the soft water generated after treatment by the resin core to other flow paths.

[0085] Furthermore, after long-term adsorption of calcium and magnesium ions, the resin core's ability to adsorb these ions decreases. Therefore, the resin tank 010 is also connected to the brine tank 030 of the water purifier / softener 001 to transport the resin regenerator in the brine tank 030 to the first resin chamber 012h and the second resin chamber 012k for resin core regeneration. Specifically, one of the two first channels 012x is connected to the brine tank 030 of the water purifier / softener 001 to receive the resin regenerator transported from the brine tank 030 and to transport it to the first resin chamber 012h and the second resin chamber 012k. The ions in the resin regenerator exchange with the calcium and magnesium ions adsorbed on the resin core, generating resin regeneration waste liquid. The other first channel 012x is connected to the outside of the resin tank 010 to transport the waste resin regeneration waste liquid to the outside of the resin tank 010. In this process, after the ions in the resin regenerator exchange with the calcium and magnesium ions adsorbed on the resin core, some of the ions in the resin regenerator will be adsorbed on the resin core. Water needs to be introduced into the first resin chamber 012h and the second resin chamber 012k through one of the first channels 012x to rinse the resin core, remove the residual resin regenerator on the resin core, and realize the regeneration of the resin core (that is, to achieve the state in which the resin core can re-adsorb calcium and magnesium ions).

[0086] In this embodiment, during the process of converting hard water into soft water in the resin tank 010, the flow rate of the fluid entering and exiting the first channel 012x is relatively large. During the resin regeneration process, the flow rates of the resin regenerator, resin regeneration waste liquid, and water used to rinse the resin regenerator are relatively low in the first resin chamber 012h and the second resin chamber 012k. The flow rate of the fluid in the first section 012a and the second section 012b is easily affected by the flow path and flow area of ​​the first section 012a and the second section 012b. Therefore, in this embodiment, by setting a first plug 015 in the first channel 012x and setting the positions of the first opening 012d and the second opening 012e, the flow rate stability of the low-velocity fluid during the resin regeneration process is well regulated.

[0087] When the resin tank 010 has two first channels 012x, correspondingly, the resin tank 010 has two first plugs 015, the sealing part 0151 of each first plug 015 seals the first segment 012a of one of the first channels 012x, and the resin tank 010 has two second plugs 016, each second plug 016 seals the end of the second segment 012b of one of the first channels 012x away from the first segment 012a.

[0088] In some embodiments, when the resin tank 010 has two first channels 012x, in the second direction Y, the mating interfaces 012c of the two first channels 012x are collinear, the first openings 012d of the two first channels 012x are collinear, and the second openings 012e of the two first channels 012x are collinear. Optionally, in the second direction Y, the preset planes 012e of the two first channels 012x overlap.

[0089] Please refer to the diagram again. Figure 3 The tank body 0120 includes a first cylindrical body 0123 and a second cylindrical body 0124. The resin tank 010 also includes two plugs 013. One plug 013 and the first cylindrical body 0123 enclose a first resin cavity 012h, and the other plug 013 and the second cylindrical body 0124 enclose a second resin cavity 012k. A main pipe 0121 is integrally formed with the first cylindrical body 0123 and the second cylindrical body 0124, with one portion of the main pipe 0121 protruding from the surface of the first cylindrical body 0123 away from the plug 013, and the other portion of the main pipe 0121 protruding from the surface of the second cylindrical body 0124 away from the plug 013. This design prevents the main pipe 0121 from obstructing the installation of other structural components when it is located inside the first cylindrical body 0123 and the second cylindrical body 0124. It also allows for flexible design of the length of the first channel 012x, ensuring that the length of the first channel 012x is not limited by the dimensions of the first cylindrical body 0123 and the second cylindrical body 0124.

[0090] In some embodiments, the first cylinder 0123 has a first convex top wall 0123m, which protrudes away from the corresponding plug 013. The outer surface of the first convex top wall 0123m is a convex arc-shaped surface. The outer surface of the first convex top wall 0123m has a first vertex that is furthest from the plug 013. The first vertex is located on the first central axis S1. The second cylinder 0124 has a second convex top wall 0123n, which protrudes away from the corresponding plug 013. The outer surface of the second convex top wall 0123n is a convex arc-shaped surface. The outer surface of the second convex top wall 0123n has a second vertex that is furthest from the plug 013. The second vertex is located on the second central axis S2. In this configuration, each main pipe 0121 is located on the same side of the first and second vertices in the second direction Y. Utilizing the shape characteristics of the first and second convex top walls 0123m and 0123n, the main pipe 0121 is positioned at the edge regions of the first and second convex top walls 0123m and 0123n, making full use of space and further reducing the axial dimension of the resin tank 010. Optionally, the supporting plane 012f of the main pipe 0121 may be on the same plane as the first and second vertices.

[0091] In some embodiments, please refer to Figure 3 The tank body 0120 also includes multiple first docking parts 0125 along the first direction X, wherein a portion of the first docking parts 0125 are located between the first cylinder 0123 and the second cylinder 0124, and another portion of the first docking parts 0125 are located outside the first cylinder 0123 and the second cylinder 0124. The water purification system 003 includes a water purification mounting shell, which includes multiple second docking parts. The multiple second docking parts are inserted and engaged with the multiple first docking parts in a one-to-one manner to facilitate the assembly of the water purification system 003 and the water softening system 002, thereby limiting the relative positions of the water purification system 003 and the water softening system 002, improving installation stability, and increasing assembly efficiency. Optionally, the tank body 0120 also includes three first docking parts 0125, one of which is located between the first cylinder 0123 and the second cylinder 0124, another of which is located on the side of the first cylinder 0123 away from the second cylinder 0124, and the third of which is located on the side of the second cylinder 0124 away from the first cylinder 0123. Correspondingly, the water purification system 003 has three second docking parts, and the three second docking parts are inserted and engaged with the three first docking parts one by one.

[0092] The tank body 0120 also includes multiple branch pipes 0122. Each branch pipe 0122 has a second channel 012g inside. Each branch pipe 0122 is located on one of the main pipes 0121, and the second channel 012g of each branch pipe 0122 is connected to the corresponding first channel 012x at the interface 012c. Each branch pipe 0122 is integrally set with the corresponding main pipe 0121.

[0093] like Figure 8 As shown, the soft water valve 020 includes two first connecting pipes 0220, one of which is a first tank connector 0222 and the other is a second tank connector 0223. The first tank connector 0222 is assembled with one of the branch pipes 0122 so that fluid in the second channel 012g of the branch pipe 0122 can enter and exit the internal channel of the first tank connector 0222. The second tank connector 0223 is assembled with the other branch pipe 0122 so that fluid in the second channel 012g of the branch pipe 0122 can enter and exit the internal channel of the second tank connector 0223. During soft water treatment, the first tank connector 0222 is used to supply raw water to the resin tank 010, and the second tank connector 0223 is used to receive the soft water output from the resin tank 010. During resin regeneration treatment, the second tank connector 0223 is used to receive the resin regenerant input from the brine tank 030, and the first tank connector 0222 receives the resin regeneration waste liquid output from the resin tank 010. In this embodiment, each branch pipe 0122 extends axially along the first resin cavity 012h to one of the first docking pipes 0220. The main pipe 0121 is provided with a supporting plane 012f to support the soft water valve 020, so that the soft water valve 020 is located near the docking port 012c. This facilitates the branch pipes 0122 extending toward the side where the soft water valve 020 is located to be aligned and connected with the first docking pipe 0220 of the soft water valve 020. This simplifies the pipeline design between the soft water valve 020 and the resin tank 010 and also facilitates the integrated design of the soft water system 002.

[0094] The soft water valve 020 also includes two second connecting pipes 021. One of the two second connecting pipes 021 is a raw water inlet pipe 0211 and the other is a first soft water inlet pipe 0212. The first soft water inlet pipe 0212 is connected to the water purification system 003. The raw water inlet pipe 0211 is used to connect to the raw water source to receive the raw water supplied by the raw water source. The raw water that enters the soft water valve 020 through the raw water inlet pipe 0211 enters the first resin chamber 012h and the second resin chamber 012k through the first tank pipe 0222. After being treated by the resin core to form soft water, it enters the soft water valve 020 through the second tank pipe 0223 and is transported to the water purification system 003 through the first soft water inlet pipe 0212.

[0095] The soft water valve 020 also includes a main valve body, which is located on the support plane 012f. Since there is suitable space on both sides of the main valve body in the first direction X, the first connecting pipe 0220 and the second connecting pipe 021 are provided on both sides of the main valve body along the first direction X to prevent the first connecting pipe 0220 and the second connecting pipe 021 from occupying space in the second direction Y due to improper installation.

[0096] The soft water system 002 also includes a salt tank 030. Along the first direction X, the salt tank 030 is arranged side by side with the resin tank 010, and the salt tank 030 is located on the side of the first resin chamber 012h away from the second resin chamber 012k. The salt tank 030 has a salt storage chamber that communicates with the first channel 012x, and the salt storage chamber stores resin regenerator. The soft water valve 020 also includes a brine tank connector 0224. The internal channel of the brine tank connector 0224 connects to the brine storage chamber of the brine tank 030, and also connects to the internal channel of the second tank connector 0223. During resin regeneration, the soft water valve 020 switches the brine storage chamber of the brine tank 030 to connect to the first resin chamber 012h and the second resin chamber 012k respectively through the internal channel of the second tank connector 0223. This allows the resin regenerant to directly enter the first resin chamber 012h and the second resin chamber 012k via the second tank connector 0223, without needing to pass through the main valve body of the soft water valve 020. Along the first direction X, the first connecting connector 0220 and the brine tank connector 0224 are located on the same side of the main valve body to allow for the design of a pipeline structure that connects the brine tank connector 0224 to the brine storage chamber of the brine tank 030.
