[0050] In the related technical field, the design of the waterway switching control mechanism of the existing waterway plate is relatively complex, which is not conducive to assembly control, has high cost, and has poor switching accuracy.

[0051] The utility model provides a water circuit control system and a water softening device.

[0053] The water softening device in the present application includes a waterway control system 10, a waterway component 20, a salt box and a resin tank 30, etc., wherein the waterway control system 10 includes a switching component 100, a control component 200 and a driving component 600, etc.

[0054] The adapter assembly 100 is connected between the soft water valve and the water channel component 20. The resin tank 30 is used to contain 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 the brine or raw water in contact with 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.

[0055] The soft water valve is used to control the water inlet and outlet of the soft water device and the switching of each flow path to realize different working modes of the soft water device. The working modes include service mode, salt absorption mode, slow wash mode, bypass mode, backwash mode, water replenishment mode and water mixing mode.

[0056] The salt box is used to provide salt water for resin backwashing. The salt box is connected to the salt absorption flow path of the adapter assembly 100 through a pipeline, and then communicated with the water channel component 20 or the resin tank 30. The water channel component 20 is used to connect with multiple resin tanks 30 to achieve parallel connection of multiple resin tanks 30.

[0057] The adapter assembly 100 is provided with a sewage discharge channel, one end of which is connected to the resin end of the resin tank 30 to lead the sewage after backwashing out of the resin tank 30, and the other end is connected to the accommodating cavity 111 of the outer valve body 110 through the second valve port 113. The first valve port 112 is a sewage discharge port, which is connected to the first valve port 112 through the accommodating cavity 111 to discharge the pollution to a designated location.

[0058] The adapter assembly 100 includes an outer valve body 110 and an inner valve body 120 . The outer valve body 110 and the inner valve body 120 are detachably connected. The outer valve body 110 is used to provide a connection direction of the accommodating cavity 111 and the first valve port 112 and the second valve port 113 . Part of the inner valve body 120 is arranged in the accommodating cavity 111 and is located between the first valve port 112 and the second valve port 113. The inner valve body 120 has an inner valve cavity 121 that penetrates along the axial direction. The outer peripheral wall of the inner valve cavity 121 is provided with an inner valve port 123a that is connected to the inner valve cavity 121. The inner end of the inner valve body 120 is provided with a valve opening and closing port 123b, which is used to connect the second valve port 113 and the inner valve cavity 121. The control component 200 is movably arranged in the inner valve cavity 121, and one end is abutted against the valve opening and closing port 123b. In this way, the inner valve body 120 cooperates with the control component 200 to control the on-off between the first valve port 112 and the second valve port 113.

[0059] The driving component 600 can be a soft water valve or a separate driving component. This embodiment is described using the driving component 600 as a soft water valve. Other embodiments can be implemented with reference to this embodiment. Using a soft water valve as the driving component 600 can reduce the volume occupied by a separate driving component; at the same time, the synchronization between the control component 200 and the soft water valve can be improved.

[0060] The driving assembly 600 includes a cam mechanism 610 and a matching piece 620. The cam mechanism 610 is arranged on the rotating gear of the soft water valve. Through the arrangement of the cam mechanism 610, the matching piece 620 can be intermittently driven by rotation, so that the control assembly 200 is operated as required to control the opening and closing between the first valve port 112 and the second valve port 113. The matching piece 620 connects the cam mechanism 610 and the control assembly 200 to transmit motion and power. The matching piece 620 is provided with a first matching surface 623 and a second matching surface 624 opposite to each other. The first matching surface 623 is movably abutted against the cam mechanism 610 to ensure that the matching piece 620 can move along with the movement of the cam mechanism 610. The second matching surface 624 is movably abutted against the control assembly 200 to transmit motion and power to the control assembly 200 to realize the opening and closing of the first valve port 112 and the second valve port 113.

[0061] The present application sets a mating piece 620 between the control component 200 and the cam mechanism 610, and sets two opposite first mating surfaces 623 and second mating surfaces 624 on the mating piece 620 to respectively cooperate with the control component 200 and the cam mechanism 610. In this way, the abutment area between the control component 200 and the cam mechanism 610 is increased through the contact between the surfaces, thereby improving the accuracy and stability of the driving component 600 and the control component 200 in controlling the on-off between the sewage outlet and the transfer interface.

[0062] Reference Figures 4 to 7According to an embodiment of the utility model, the matching piece 620 is provided with a first limiting groove 623a, the first limiting groove 623a extends along the moving direction of the control component 200 relative to the matching piece 620, the opening of the first limiting groove 623a faces the control component 200, and the bottom surface of the first limiting groove 623a forms a second matching surface 624. It can be understood that the design of the first limiting groove 623a enables the control component 200 to move along a specific path, thereby increasing the accuracy and stability of the movement. At the same time, the second matching surface 624, as a connection point, is arranged to be in active contact with the control component 200, thereby ensuring the effective transmission of force and the stable operation of the control component 200. The bottom surface of the first limiting groove 623a forms the second matching surface 624, and the bottom surface of the first limiting groove 623a, as the second matching surface 624, contacts the control component 200, and transmits the movement and power of the cam mechanism 610 to the control component 200. The process of motion transmission is simplified, and the efficiency and accuracy of motion transmission are improved. By adjusting the size and shape of the first limiting groove 623a, the connection between the control component 200 and the matching component 620 can be customized and adjusted according to actual needs, thereby improving the versatility and flexibility of the system.

[0063] Reference Figure 6 According to an embodiment of the utility model, the second mating surface 624 is provided with a first inclined portion 623b, a straight portion 623c and a second inclined portion 623d in sequence along the moving direction of the control assembly 200 relative to the mating piece 620, and the first inclined portion 623b and the second inclined portion 623d are arranged in opposite directions. It can be understood that the inclination of the first inclined portion 623b and the second inclined portion 623d in different directions helps to guide the precise movement of the control assembly 200, so that the control assembly 200 can move more stably in a specific direction. Among them, the first inclined portion 623b is used to cooperate with the rotation of the cam mechanism 610 to guide and press the control mechanism so that the control mechanism is in a state of gradually connecting the first valve port 112 and the second valve port 113, and the straight portion 623c is set to keep the first valve port 112 and the second valve port 113 in a connected state, and the second inclined portion 623d is used to cooperate with the control mechanism to smoothly transition and cut off the connection between the first valve port 112 and the second valve port 113. This ensures that the control component 200 will not deviate laterally during movement, thereby improving the accuracy of the switch.

[0064] Reference Figure 6According to one embodiment of the utility model, the first mating surface 623 includes an abutting raised surface, and the cam mechanism 610 abuts against the abutting raised surface. The provision of the abutting raised surface enables the mating member 620 to contact the cam mechanism 610 more stably, reducing vibration and deviation during movement. The accuracy and efficiency of motion transmission can be ensured by the close contact between the abutting raised surface and the cam mechanism 610. The shape and size of the abutting raised surface can be customized according to actual needs to adapt to cam mechanisms 610 of different types and specifications. This flexibility enables the utility model to be applicable to various different waterway control systems 10 to meet different application needs.

[0065] Reference Figure 5 According to one embodiment of the utility model, the matching piece 620 includes a rotating part 621 and a swing arm part 622, and the rotating part 621 is connected to one end of the swing arm part 622. By combining the rotating part 621 and the swing arm part 622, the matching piece 620 can adapt to different motion trajectories and directions more flexibly. The rotating part 621 provides the ability of rotational motion, while the swing arm part 622 provides the ability of swinging motion, so that the matching piece 620 can better adapt to the motion characteristics of the cam mechanism 610. At the same time, the connection design of the rotating part 621 and the swing arm part 622 simplifies the structure of the matching piece 620, reduces the manufacturing cost, and facilitates installation and maintenance. This structural design is also conducive to reducing the size and weight of the entire waterway control system 10, making it more compact and lightweight.

[0066] Reference Figure 5 According to an embodiment of the utility model, one of the driving assembly 600 and the swing arm part 622 is provided with a limiting column, and the other is provided with a second limiting groove 625, the second limiting groove 625 is opened along the rotation direction, and the limiting column is used to limit and abut with the second limiting groove 625. The cooperation between the limiting column and the second limiting groove 625 enables the matching piece 620 to be accurately limited during the rotation process, thereby preventing excessive rotation or misalignment during the rotation process. The precise positional relationship between the matching piece 620 and the driving assembly 600 is ensured, thereby improving the accuracy and stability of the waterway control. The opening direction of the second limiting groove 625 is consistent with the rotation direction, which is convenient for guiding the limiting column to move along the correct path and improving the stability and accuracy of the motion transmission. At the same time, the close contact between the limiting column and the second limiting groove 625 also helps to reduce vibration and noise during the movement process.

[0067] Reference Figures 5 to 7According to an embodiment of the utility model, the fitting 620 further includes a reinforcing rib 626, and the adjacent two sides of the reinforcing rib 626 are respectively connected to the rotating part 621 and the swing arm part 622. The addition of the reinforcing rib 626 increases the structural stability of the fitting 620 and improves its ability to resist bending and twisting. It can ensure that the fitting 620 maintains its original shape and size during long-term use, thereby ensuring the stability and accuracy of waterway control. The design of the reinforcing rib 626 can also reduce stress concentration and improve the ability of the fitting 620 to resist fatigue stress. By reasonably distributing the position and number of the reinforcing ribs 626, the structure of the fitting 620 can be further optimized to make it more in line with the needs of practical applications.

[0068] Reference Figure 8 and Fig. 9 According to one embodiment of the utility model, the adapter assembly 100 includes an inner valve body 120 and an outer valve body 110, an accommodating cavity 111, a first valve port 112, a second valve port 113 and an accommodating opening in the outer valve body 110, a portion of the inner valve body 120 is fixed in the accommodating cavity 111 through an accommodating opening 114, and the inner end of the inner valve body 120 is located between the first valve port 112 and the second valve port 113, the inner valve body 120 is provided with an inner valve cavity 121, an inner valve port 123a and a valve opening and closing port 123b, the valve opening and closing port 123b is located at the inner end, and the inner valve port 123a communicates with the first valve port 112 and the inner valve cavity 121. It is understandable that the adapter assembly 100 includes an outer valve body 110 and an inner valve body 120 , and the outer valve body 110 and the inner valve body 120 are detachably connected. The outer valve body 110 is used to provide a connection direction between the accommodating chamber 111 and the first valve port 112 and the second valve port 113 . Part of the inner valve body 120 is arranged in the accommodating cavity 111 and is located between the first valve port 112 and the second valve port 113. The inner valve body 120 has an inner valve cavity 121 that penetrates along the axial direction. The outer peripheral wall of the inner valve cavity 121 is provided with an inner valve port 123a that is connected to the inner valve cavity 121. The inner end of the inner valve body 120 is provided with a valve opening and closing port 123b, which is used to connect the second valve port 113 and the inner valve cavity 121. The control component 200 is movably arranged in the inner valve cavity 121, and one end is abutted against the valve opening and closing port 123b. In this way, the inner valve body 120 cooperates with the control component 200 to control the on-off between the first valve port 112 and the second valve port 113.

[0069] Reference Figure 8 and Fig. 9According to an embodiment of the utility model, the control component 200 includes an abutment member 210, which is movably arranged in the inner valve cavity 121 and has a conducting state and a blocking state for axially moving to open and close the valve opening and closing port 123b. By adjusting the position of the abutment member 210, the opening and closing state of the valve opening and closing port 123b can be controlled, thereby realizing the conduction or blocking of the waterway. The on-off setting of the valve opening and closing port 123b is simplified, and the reliability and stability of the waterway control are improved. When the abutment member 210 moves away from the valve opening and closing port 123b, it will change the opening of the valve opening and closing port 123b, thereby realizing the conduction of the waterway. At this time, the water flow can flow into the inner valve cavity 121 from the second valve port 113, and then flow out toward the first valve port 112 through the inner valve port 123a, thereby realizing the conduction of the water flow. On the contrary, when the abutment member 210 moves toward the valve opening and closing opening 123b, it will block the valve opening and closing opening 123b, thereby achieving the blocking of the waterway. At this time, the water flow cannot flow through the valve opening and closing opening 123b, thereby achieving the closure of the waterway.
