[0038] A water softener is a device that uses cation exchange resin to remove calcium and magnesium ions from water, reduce the hardness of raw water, and thus soften hard water. Water softeners are currently widely used in industrial and energy systems and have strong equipment attributes. In household use, the soft water produced by a water softener usually has the effects of reducing scale in water heating equipment such as water heaters, wall-mounted boilers, electric water heaters, and bathrooms, avoiding pipe blockage, reducing the attenuation of heat exchange efficiency of heating equipment, reducing the use of detergents, being more friendly to human skin, and making clothes softer and brighter in color after washing.

[0042] The water softening device in the present application includes an adapter assembly 200, a water softening valve 20, a water channel component 100, a salt box and a resin tank 30, etc., wherein 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 contain resin to soften the raw water to be softened, and the resin tank 30 is provided with a central pipe and a water distribution mechanism, the water distribution mechanism is used to evenly distribute the salt water or raw water to contact the resin, and the central pipe is used to lead the softened soft water out of the resin tank 30 or introduce the salt water 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 each flow path to realize different working modes of the water softening device, wherein the working mode includes service mode, salt absorption mode, slow washing mode, bypass mode, backwash mode, water replenishment mode and water mixing mode. The salt box is used to provide salt water for resin backwashing, and the salt box is connected to the salt absorption flow path of the adapter assembly 200 through a pipeline, and then communicated with the water channel component 100 or the resin tank 30. The water channel member 100 is used to connect to a plurality of resin tanks 30 to realize parallel connection of the plurality of resin tanks 30 .

[0043] The present application is described by taking the adapter assembly 200 and the water channel component 100 as a separate configuration as an example.

[0044] The water channel component 100 is the core part of the water channel control assembly 10, and defines a plurality of water channels 110 therein. The water channels 110 are elongated channels in the water channel component 100, which are used to transport and guide water flow. They are the main water flow paths in the water softening device, ensuring that the water flows in a preset direction and process.

[0045] The first interface 120 is disposed on the outer wall of the water channel member 100, corresponding to the water channel 110. The first interface 120 is used as a connection point for docking with the adapter assembly 200, thereby achieving the transfer and connection of water flow.

[0046] The adapter assembly 200 is a component that is detachably connected to the water channel component 100 and is used to achieve the transfer between different water channels. The transfer channel 210 is a channel in the adapter assembly 200, corresponding to the water channel 110. The transfer channel 210 is used to receive the water flow from the water channel 110 and transfer it as needed to achieve flexible control of the water flow.

[0047] The second interface 220 is provided on the outer wall of the adapter assembly 200, corresponding to the first interface 120. The second interface 220 is used as a docking point. When the adapter assembly 200 is connected to the water channel component 100, the water channel 110 is docked and connected with the adapter channel 210, thereby realizing the connection and connection of water flow.

[0048] When the adapter assembly 200 is connected to the water channel component 100, the first interface 120 and the second interface 220 are docked to form a tight connection. After the docking is completed, a smooth connection is formed between the water channel 110 and the adapter channel 210, so that the water can flow as needed. In this way, the flexibility and adaptability of the device are improved, and the assembly, maintenance, replacement and inspection of the components are facilitated through the detachable connection method.

[0049] 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 arranged 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.

[0050] 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 via a second adapter interface correspondingly provided on the outer surface of the adapter assembly 200, and the other end is connected to the central tube 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 export the soft water in the resin tank 30 out of the resin tank 30 to provide soft water to the user.

[0051] 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.

[0052] The adapter assembly 200 is provided with a salt absorption channel connected to the salt box, and the salt absorption channel is communicated with the salt mixing channel. When raw water is introduced into the salt mixing channel, salt water can be mixed through the salt absorption channel to provide salt water for resin regeneration.

[0053] A backwash flow channel is provided in the adapter assembly 200, one end of the backwash flow channel 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 reversely flush the resin to regenerate it.

[0054] 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, so as to integrate the water inlet and outlet of the resin tank 30 or the water path component 100, and reduce the setting of different openings and separate docking.

[0055] The present application arranges the water path component 100 and the adapter assembly 200 to be detachably connected, so that when the water path component 100 and the adapter assembly 200 are tested, the adapter assembly 200 and the water path 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 path control assembly 10.

[0056] The present application arranges the water path component 100 and the adapter assembly 200 to be detachably connected, so that when the water path component 100 and the adapter assembly 200 are tested, the adapter assembly 200 and the water path 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 path control assembly 10.

[0057] Reference Figure 1 and Figure 2 According to an embodiment of the utility model, 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 function of the connecting pipe 130 is mainly to connect and transfer 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, which can achieve fast and accurate installation and disassembly. The plug-in matching method simplifies the installation process, improves the assembly efficiency of the device, and also ensures the continuity and stability of the water flow.

[0058] Reference Figures 2 to 4 According to an embodiment of the utility model, a slot 231 is provided on the outer peripheral wall of the plug-in column 230, a bayonet 131 is provided on the outer peripheral wall of the connecting pipe 130, and the waterway control assembly 10 further includes a plug-in component 300, and the plug-in component 300 passes through the bayonet 131 and is plugged into the slot 231. It can be understood that the opening of the slot 231 is located on the outer annular surface of the side wall, which is convenient for the insertion and fixation of the plug-in component 300. The bayonet 131 matches the slot 231, ensuring the alignment and fixation between the plug-in column 230 and the connecting pipe 130. In addition, the waterway control assembly 10 further includes a plug-in component 300, which passes through the bayonet 131 and is plugged into the slot 231. The plug-in component 300 plays a role of further reinforcement and stabilization, preventing the plug-in column 230 and the connecting pipe 130 from loosening or shifting under external force or long-term use.

[0059] Reference Figure 4 According to an embodiment of the utility model, the plug-in connector 300 has a plurality of mutually symmetrical plug-in arms 310, the slot 231 is annular, and a plurality of bayonet holes 131 corresponding to the plug-in arms 310 are arranged on the outside of the connecting tube 130, and each plug-in arm 310 passes through each corresponding bayonet hole 131 and is connected to the corresponding slot 231. It can be understood that the number of plug-in 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-in column 230, and the axial limit is realized by the cooperation between the plug-in connector 300 and the plug-in column 230, thereby increasing the limit capacity and fixing effect between the plug-in column 230 and the connecting tube 130. At the same time, the annular slot 231 can also adapt to different sizes and shapes of the plug-in connector 300, and has better versatility and adaptability. The outer side 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 to the plug-in arms 310 one by one, ensuring that the plug-in component 300 can be accurately and firmly inserted into the card slot 231. The provision of a plurality of bayonet holes 131 enables the plug-in component 300 to disperse the plug-in force more evenly and improves the stability of the overall structure. Each plug-in arm 310 passes through each corresponding bayonet hole 131 and is snapped into the corresponding card slot 231. The snap-in method is simple and fast, and the installation of the plug-in component 300 can be completed quickly. At the same time, due to the close fit between the plug-in component 300, the card slot 231 and the bayonet hole 131, the connection between the plug-in column 230 and the connecting tube 130 is more firm and reliable.

[0060] Reference Figure 2 According to one embodiment of the utility model, a sealing groove 232 is provided on the outer wall of the plug-in column 230, and the 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 can be understood that the design of the sealing groove 232 can ensure that the position of the sealing member is fixed, and when the sealing member 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 selection of the sealing member should have good elasticity and pressure resistance, and be able to adapt to the pressure changes and temperature fluctuations between the plug-in column 230 and the connecting pipe 130. Through close abutment and appropriate compression, the sealing member can form a reliable seal, ensure the one-way flow of water, and reduce unnecessary leakage and pressure loss.

[0061] Reference Figure 2According to an embodiment of the present invention, the outer peripheral wall of the connecting pipe 130 is further provided with a reinforcing portion 132 extending along the axial direction of the connecting pipe 130. It is understandable that the reinforcing portion 132 extends along the axial direction of the connecting pipe 130, and can provide sufficient support and resistance, so that the connecting pipe 130 is not easy to bend or deform when subjected to external forces. This design helps to maintain the straightness and stability of the connecting pipe 130, and ensures the smooth flow of water in the connecting pipe 130.

[0062] Reference Figure 2 and Figure 3 According to an embodiment of the utility model, 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 and intersected with the first flow channel 111 and the second flow channel 112 to form a first interface 120. It can be understood 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 and intersected 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, achieving 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.

[0063] According to one embodiment of the utility model, the flow rate of the first interface 120 is greater than or equal to the flow rate 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 flow rate 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 flow rate of the first interface 120 should match or be greater than the flow rate of the central tube. A larger flow rate can ensure that sufficient water flows into the adapter assembly 200 through the first interface 120, 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 flow rate 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.

[0064] Reference Figure 1According to an embodiment of the utility model, a water channel component 100 is provided with a soft water valve installation position 140 and an adapter assembly installation position 150 arranged side by side, the adapter assembly 200 is arranged at the adapter assembly installation position 150, the soft water valve 20 is arranged at the soft water valve installation position 140, and the first interface 120 is arranged at the adapter assembly installation position 150. It can be understood that this embodiment not only simplifies the installation steps and improves the assembly efficiency, but also saves the occupied space of the device 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. At the same time, the first interface 120 is arranged at the adapter assembly installation position 150, which ensures the smooth connection of the water flow channel and further improves the overall performance and stability of the device. It also helps to reduce unnecessary space waste and optimize the structural layout of the soft water device.

[0065] The utility model also proposes a water softening device, which includes the above-mentioned water circuit control component 10. The specific structure of the water circuit control component 10 refers to the above-mentioned embodiment. Since the water softening device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0066] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
