[0049] A water softener utilizes cation exchange resins to remove calcium and magnesium ions from water, reducing the hardness of the raw water and thereby softening it. Water softeners are currently widely used in industrial and energy systems and possess a strong mechanical nature. In homes, the soft water produced by a water softener typically reduces scale buildup in water heating equipment such as water heaters, wall-mounted boilers, and electric water heaters, as well as in bathrooms. It also prevents pipe blockages, reduces heat exchange efficiency degradation in heating equipment, reduces detergent usage, and is more skin-friendly, resulting in softer, more vibrantly colored clothes.

[0050] In the relevant technical field, water channel components need to be inspected and calibrated before use. However, since existing inspection equipment is limited by the size of the inspection space and the water channel components are too large, it is impossible to effectively inspect the water channel components.

[0051] The present application provides a resin tank and a water softening device.

[0052] In an embodiment of the present application, as shown in Figures 1 to 3, the water channel control component 10 includes a water channel component 100 and an adapter component 200. A plurality of water channels 110 are defined in the water channel component 100, and a plurality of first interfaces 120 are provided on the outer wall surface of the water channel component 100 corresponding to the plurality of water channels 110; the adapter component 200 is detachably connected to the water channel component 100, and a plurality of adapter channels 210 are defined in the adapter component 200. A second interface 220 is provided at a position corresponding to the first interface 120 on the outer wall surface of the adapter component 200, and the water channels 110 and the adapter channels 210 are connected to each other through the docking between the first interface 120 and the second interface 220.

[0053] The water softening device in this application includes an adapter assembly 200, a water softening valve 20, a water channel component 100, a brine tank, and a resin tank 30. The adapter assembly 200 is connected between the water softening valve 20 and the water channel component 100. The resin tank 30 is used to hold resin to soften the raw water to be softened. The resin tank 30 is provided with a central pipe and a water distribution mechanism. The water distribution mechanism is used to evenly distribute brine or raw water to contact the resin. The central pipe is used to lead the softened soft water out of the resin tank 30 or to introduce brine into the resin tank 30. The water softening valve 20 is used to control the water inlet and outlet of the water softening device and the switching of various flow paths to achieve different operating modes of the water softening device. The operating modes include service mode, brine absorption mode, slow wash mode, bypass mode, backwash mode, water replenishment mode, and water mixing mode. The brine tank is used to provide brine for resin backwashing. The brine tank is connected to the brine absorption flow path of the adapter assembly 200 through a pipe and then connected to the water channel component 100 or the resin tank 30. The water channel member 100 is used to connect to the plurality of resin tanks 30 to realize parallel connection of the plurality of resin tanks 30 .

[0054] The present application is described by taking the example of a separate configuration of the adapter assembly 200 and the water channel component 100 .

[0055] The water channel member 100 is the core of the water control assembly 10, defining a plurality of water channels 110 within it. These channels 110 are elongated passages within the water channel member 100 that transport and direct water flow. They serve as the primary flow paths within the water softener, ensuring that water flows in a predetermined direction and pattern.

[0056] The first interface 120 is provided on the outer wall of the water channel member 100, corresponding to the water channel 110. The first interface 120 serves as a connection point for docking with the adapter assembly 200, thereby achieving water flow transfer and communication.

[0057] Adapter assembly 200 is a removable component connected to waterway member 100, used to facilitate the transition between different waterways. Adapter channel 210 is a channel within adapter assembly 200 that corresponds to waterway channel 110. Adapter channel 210 receives water from waterway channel 110 and transfers it as needed, enabling flexible control of the water flow.

[0058] The second interface 220 is provided on the outer wall of the adapter assembly 200 and corresponds to the first interface 120. The second interface 220 serves as a docking point. When the adapter assembly 200 is connected to the water channel member 100, the water channel 110 and the adapter channel 210 are docked and connected, thereby achieving water flow transfer and connection.

[0059] When the adapter assembly 200 is connected to the water channel member 100, the first interface 120 and the second interface 220 mate, forming a tight connection. Once connected, a smooth connection is established between the water channel 110 and the adapter channel 210, allowing water to flow as desired. This enhances the device's flexibility and adaptability, and the detachable connection facilitates assembly, maintenance, replacement, and inspection of the components.

[0060] Specifically, a first flow path is provided in the adapter assembly 200, and the first flow path is connected to the soft water valve 20 and the first interface 120 of the water path component 100 through a second adapter interface correspondingly provided on the outer surface of the adapter assembly 200, so that raw water can be introduced from one side of the soft water valve 20 to the resin end of the resin tank 30.

[0061] A second flow path is provided in the adapter assembly 200. One end of the second flow path is connected to the soft water valve 20 through a second adapter interface correspondingly provided on the outer surface of the adapter assembly 200, and the other end is connected to the central pipe of the water path component 100 or the resin tank 30 through the adapter cavity, or the other end is directly connected to the first interface 120 of the water path component 100. The second flow path is used to guide the soft water in the resin tank 30 out of the resin tank 30 to provide soft water to the user.

[0062] A salt mixing flow channel is provided in the adapter assembly 200, one end of which is connected to the soft water valve 20 for introducing raw water or salt water, and the other end is connected to the central tube of the water channel component 100 or the resin tank 30 through the adapter cavity, or the other end is directly connected to the central tube of the water channel component 100 or the resin barrel. The salt mixing flow channel is used to provide salt water for resin regeneration.

[0063] The adapter assembly 200 is provided with a salt absorption flow channel connected to the salt box. The salt absorption flow channel is communicated with the salt mixing flow channel. When raw water is introduced into the salt mixing flow channel, salt water can be mixed through the salt absorption flow channel to provide salt water for resin regeneration.

[0064] A backwash flow channel is provided in the adapter assembly 200, one end of which is connected to the soft water valve 20 for introducing raw water, and the other end is connected to the central tube of the water channel component 100 or the resin tank 30 through the adapter cavity, or the other end is directly connected to the central tube of the water channel component 100 or the resin tank 30. The backwash flow channel is used to inject raw water into the middle and lower pipes to backwash the resin to regenerate it.

[0065] A transfer chamber is provided in the transfer assembly 200, which is used to connect one end of the second flow path, the salt mixing flow path and the backwash flow path with the central pipe of the water path component 100 or the resin tank 30, thereby integrating the water inlet and outlet of the resin tank 30 or the water path component 100, reducing the setting of different openings and separate docking.

[0066] The present application arranges the water channel component 100 and the adapter assembly 200 to be detachably connected, so that when the water channel component 100 and the adapter assembly 200 are tested, the adapter assembly 200 and the water channel component 100 can be disassembled and tested separately, thereby reducing the volume of a single component during testing, making it easier to use existing testing equipment to test the water channel control assembly 10.

[0067] The present application arranges the water channel component 100 and the adapter assembly 200 to be detachably connected, so that when the water channel component 100 and the adapter assembly 200 are tested, the adapter assembly 200 and the water channel component 100 can be disassembled and tested separately, thereby reducing the volume of a single component during testing, making it easier to use existing testing equipment to test the water channel control assembly 10.

[0068] 1 and 2 , in some embodiments, a connecting pipe 130 is provided at a position of the waterway component 100 corresponding to the first interface 120, and a plug-in column 230 is provided at a position of the adapter assembly 200 corresponding to the second interface 220, and the plug-in column 230 and the connecting pipe 130 are plugged in. It can be understood that the main function of the connecting pipe 130 is to connect and divert water flow, extending from the inside of the waterway component 100 to the outside, providing a reliable access point for the adapter assembly 200. Through the connecting pipe 130, the water channel 110 is expanded, providing sufficient space and stability for the insertion of the plug-in column 230. The design of the plug-in column 230 enables the adapter assembly 200 to fit closely with the connecting pipe 130 to form a reliable connection. The size and shape of the plug-in column 230 match the connecting pipe 130, enabling quick and accurate installation and disassembly. The plug-in fitting method simplifies the installation process, improves the assembly efficiency of the device, and also ensures the continuity and stability of the water flow.

[0069] Referring to Figures 2 to 4 , in some embodiments, a slot 231 is provided on the outer circumferential wall of the plug post 230, and a socket 131 is provided on the outer circumferential wall of the connecting tube 130. The waterway control assembly 10 also includes a connector 300, which passes through the socket 131 and is inserted into the slot 231. It will be appreciated that the opening of the socket 231 is located on the outer annular surface of the side wall, facilitating the insertion and securement of the connector 300. The socket 131 mates with the slot 231, ensuring alignment and securement between the plug post 230 and the connecting tube 130. Furthermore, the waterway control assembly 10 also includes a connector 300, which passes through the socket 131 and is inserted into the slot 231. The connector 300 further reinforces and stabilizes the plug post 230 and the connecting tube 130, preventing them from loosening or shifting due to external forces or prolonged use.

[0070] 4 , in some embodiments, the connector 300 has a plurality of mutually symmetrical plug arms 310, the slot 231 is annular, and the outer side of the connecting tube 130 is provided with a plurality of bayonet holes 131 corresponding to each of the plug arms 310, and each plug arm 310 passes through each corresponding bayonet hole 131 and is connected to the corresponding slot 231. It is understandable that the number of plug arms 310 can be selected according to actual needs to provide sufficient support and fixing effect. The slot 231 is annularly arranged on the outer peripheral wall of the plug post 230, and the axial limitation is achieved by the cooperation between the connector 300 and the plug post 230, thereby increasing the limiting capacity and fixing effect between the plug post 230 and the connecting tube 130. At the same time, the annular slot 231 can also adapt to different sizes and shapes of the connector 300, and has better versatility and adaptability. The outside of the connecting tube 130 is provided with a plurality of bayonet holes 131 corresponding to each plug-in arm 310. The bayonet holes 131 correspond one-to-one with the plug-in arms 310, ensuring that the connector 300 can be accurately and securely inserted into the slot 231. The provision of multiple bayonet holes 131 enables the connector 300 to more evenly distribute the plugging force, improving the stability of the overall structure. Each plug-in arm 310 passes through a corresponding bayonet hole 131 and snaps into the corresponding slot 231. The snap-in method is simple and quick, and the installation of the connector 300 can be completed quickly. At the same time, due to the close fit between the connector 300, the slot 231, and the bayonet hole 131, the connection between the plug post 230 and the connecting tube 130 is more secure and reliable.

[0071] 2 , in some embodiments, a sealing groove 232 is provided on the outer wall of the plug-in column 230, and a sealing member is sleeved in the sealing groove 232, and the sealing member is sealed and abutted between the outer wall of the plug-in column 230 and the inner wall of the connecting pipe 130. It is understandable that the design of the sealing groove 232 can ensure that the position of the seal is fixed, and when the seal abuts between the plug-in column 230 and the connecting pipe 130, an effective seal can be formed to prevent water from leaking from the connection. The seal should have good elasticity and pressure resistance, and be able to adapt to pressure changes and temperature fluctuations between the plug-in column 230 and the connecting pipe 130. Through close abutment and appropriate compression, the seal can form a reliable seal, ensure the one-way flow of water, and reduce unnecessary leakage and pressure loss.

[0072] Referring to Figure 2 , in some embodiments, the outer peripheral wall of the connecting tube 130 is further provided with a reinforcement portion 132 extending along the axis of the connecting tube 130. It will be appreciated that the reinforcement portion 132 extends along the axis of the connecting tube 130, providing sufficient support and resistance, preventing the connecting tube 130 from bending or deforming when subjected to external forces. This design helps maintain the straightness and stability of the connecting tube 130, ensuring smooth water flow within the connecting tube 130.

[0073] 2 and 3 , in some embodiments, the water passage 110 includes a first flow channel 111 and a second flow channel 112 arranged side by side, and the connecting pipe 130 includes a first connecting pipe 130 and a second connecting pipe 130. The connecting pipe 130 is arranged between the first flow channel 111 and the second flow channel 112, and the connecting pipe 130 is staggered with the first flow channel 111 and the second flow channel 112 to form a first interface 120. It is understandable that the connecting pipe 130 includes a first connecting pipe 130 and a second connecting pipe 130, which correspond to the first flow channel 111 and the second flow channel 112, respectively. The connecting pipe 130 is arranged between the first flow channel 111 and the second flow channel 112, and staggered with them to form the first interface 120. The staggered intersection design can ensure a tight connection between the connecting pipe 130 and the two flow channels, while avoiding direct connection between the two flow channels, realizing the diversion and regulation of the water flow, reducing the impact force and vibration of the water flow on the interface, and improving the stability and reliability of the device. The staggered intersection can also reduce the spatial arrangement volume.

[0074] In some embodiments, the circulation volume of the first interface 120 is greater than or equal to the circulation volume of the central tube. It is understandable that the central tube plays a core diversion role in the water softening device, and the size of its circulation volume directly affects the soft water output efficiency of the entire device. In order to maintain the smooth flow of water and sufficient processing capacity, the circulation volume of the first interface 120 should match or be larger than the circulation volume of the central tube. A larger circulation volume can ensure that sufficient water flows through the first interface 120 into the adapter assembly 200, maintaining the continuity and stability of the water flow. It helps to improve the overall processing capacity and efficiency of the water softening device and ensure the water quality treatment effect. In addition, the increase in circulation volume can also reduce the resistance of the water flow when passing through the first interface 120, reduce pressure loss, and further enhance the performance and stability of the water softening device.

[0075] Referring to Figure 1 , in some embodiments, a water channel component 100 is provided with a soft water valve mounting position 140 and an adapter assembly mounting position 150 arranged side by side. The adapter assembly 200 is located at the adapter assembly mounting position 150, the soft water valve 20 is located at the soft water valve mounting position 140, and the first interface 120 is located at the adapter assembly mounting position 150. It will be appreciated that by arranging the soft water valve 20 and the adapter assembly 200 side by side in the same direction of the water channel component 100, this embodiment not only simplifies the installation process and improves assembly efficiency, but also saves space in the device. Furthermore, the placement of the first interface 120 at the adapter assembly mounting position 150 ensures smooth connection of the water flow channel, further enhancing the overall performance and stability of the device. This also helps to reduce unnecessary space waste and optimize the structural layout of the water softening device.

[0076] The present application also proposes a water softening device, which includes the above-mentioned water channel control component 10. The specific structure of the water channel control component 10 refers to the above-mentioned embodiment. Since the present water softening device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0077] 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.
