Thus, the fixed assembly between the first mounting surface 120 and the second mounting surface 220 is realized. At the same time, the addition of the fastener 300 can further improve the connection stability between the soft water valve 100 and the adapter assembly 200, and prevent them from being loosened or separated during use. At the same time, the addition of the fastener 300 can also improve the reliability and durability of the entire waterway control system 10, ensuring its long-term stable operation. In addition, this design is also conducive to improving the convenience of assembly. During the assembly process, the fastening member 300 can be quickly engaged to greatly simplify the assembly steps and improve the assembly efficiency.

[0053] Of course, in other embodiments, the first card slot 131 and the second card slot 231 can be set to a special shape, or a friction structure can be added to the bottom of the first card slot 131 and the second card slot 231 to increase the friction between the fastener 300 and the first card slot 131 and the second card slot 231, thereby increasing the connection strength between the fastener 300 and the soft water valve 100 and the adapter assembly 200.

Through the fixing effect of the fastener 400, the connection strength between the fastener 300 and the first clamping portion 130 or the second clamping portion 230 can be further enhanced, ensuring the stable connection between the soft water valve 100 and the adapter assembly 200. At the same time, the addition of the fastener 400 can prevent loosening or falling off during use, thereby improving the stability and reliability of the entire waterway control system 10. At the same time, since the fastener 300 and the fastener 400 are both common standard parts, they can be easily purchased and replaced, reducing maintenance costs and difficulties.

[0055] Reference Figure 3 According to an embodiment of the utility model, the fastener 300 includes a buckle body 310 and buckle feet 320 provided at both ends of the buckle body 310 and protruding in the same direction, the buckle feet 320 are correspondingly engaged with the first card slot 131 and the second slot, and the connecting through hole 311 is provided on the buckle body 310. It can be understood that the fastener 300 can be designed to include a buckle body 310 and buckle feet 320 provided at both ends of the buckle body 310 and protruding in the same direction. The buckle feet 320 can be engaged with the first card slot 131 and the second card slot 231, and the connecting through hole 311 can be provided on the buckle body 310 to facilitate the installation and fixation of the fastener 400. In this way, the fastener 300 and the first clamping part are realized.

[0056] 130 and the second clamping portion 230 are tightly connected, while maintaining a relatively simple structure, so as to be applicable to soft water valves 100 and adapter assemblies 200 of various specifications and shapes, thereby improving their versatility and adaptability.

[0057] Reference Figure 1 and Figure 2According to an embodiment of the utility model, the first mounting surface 120 is provided with a plurality of plug-in barrels 121 protruding toward the second mounting surface 220, and the plurality of plug-in barrels 121 are correspondingly connected to the plurality of water channels 110, and the second mounting surface 220 is provided with a plurality of plug-in ports 221, and the plurality of plug-in ports 221 are correspondingly connected to the plurality of transfer channels 210, and the plug-in barrels 121 are plugged into the plug-in ports 221. It can be understood that by providing the plug-in barrels 121 and the plug-in ports 221, the rapid alignment of each water channel 110 with the transfer channel 210 can be achieved. At the same time, by providing the plug-in barrels 121 and the plug-in ports 221 on the first mounting surface 120 and the second mounting surface 220, respectively, the connection strength and stability between the soft water valve 100 and the transfer assembly 200 can be further enhanced, and the reliability and durability of the entire waterway control system 10 can be improved.

[0058] Reference Figure 2 According to one embodiment of the utility model, a sealing groove 121a is provided on the outer peripheral wall of the plug-in cylinder 121, and the sealing member is sleeved in the sealing groove 121a, and the sealing member abuts between the outer wall of the plug-in cylinder 121 and the inner wall member of the plug-in port 221. It is understandable that a sealing groove 121a may be provided on the outer peripheral wall of the plug-in cylinder 121 for placing the sealing member. The design of the sealing groove 121a can effectively fix the sealing member and keep it in the correct position to provide a good sealing effect. The sealing member can be sleeved in the sealing groove 121a and abut between the outer wall of the plug-in cylinder 121 and the inner wall of the plug-in port 221 to ensure that the water flow does not leak when passing through the plug-in cylinder 121 and the plug-in port 221. The material and shape of the sealing member can be selected according to actual needs to meet different sealing requirements and use conditions. Among them, the sealing member can be a sealing ring or a sealing pad, etc., without special limitation.

[0059] Of course, in other embodiments, a sealing step may be provided at the plug-in port 221 , and the sealing member may be directly sleeved onto the outer side of the plug-in tube 121 . The sealing member may be limited in position by alignment and plugged in so that the sealing member abuts between the plug-in port 221 and the plug-in tube 121 .

[0060] Reference Figure 2 According to an embodiment of the utility model, the inner wall of the plug port 221 is provided with an inner ring step 221a, and the outer wall of the plug barrel 121 is provided with an outer ring step 121b, and the inner ring step 221a abuts against the outer ring step 121b.

The abutment between the inner ring step 221a and the outer ring step 121b can prevent the connection from loosening or displacement, and ensure the smoothness and stability of the water flow when passing through.

[0061] Reference Figure 2 According to an embodiment of the utility model, a plurality of plug ports 221 are arranged side by side in pairs along different directions. It is understandable that a plurality of plug ports 221 can be arranged side by side in pairs along different directions, so that the compactness of the arrangement of the plug ports 221 can be improved, and a plurality of plug ports 221 can be arranged as many as possible in a smaller space, the number of plug ports 221 can be increased, and the connection flexibility between the soft water valve 100 and the adapter assembly 200 can be improved to meet the requirements of different installation angles and positions, making the connection more convenient and reliable. At the same time, the plug ports 221 of relative diameters can also be arranged symmetrically in pairs to improve the symmetry of the flow channel, thereby improving the stability of the operation of the soft water device.

[0062] Reference Figure 1 According to an embodiment of the utility model, the outer periphery of the first mounting surface 120 or the second mounting surface 220 is rounded or chamfered. In this embodiment, the outer periphery of the first mounting surface 120 or the second mounting surface 220 is rounded or chamfered to reduce the interference between the first mounting surface 120 and the second mounting surface 220, so that the contact between the first mounting surface 120 and the second mounting surface 220 is smoother, the matching accuracy between the first mounting surface 120 and the second mounting surface 220 is improved, the risk of damage caused by interference is reduced, and the reliability and stability of the entire waterway control system 10 are improved. During the installation process, due to the existence of the rounded corners or chamfers, the alignment and fixation between the first mounting surface 120 and the second mounting surface 220 become easier, which reduces the installation time and difficulty and improves the production efficiency.
