In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0053] Combine the following Figures 1 to 10The soft water control valve 10 of the utility model is described. It can be understood that the water softener absorbs metal cations such as calcium and magnesium in the raw water through the resin inside it, so as to achieve the purpose of softening water. When the resin adsorbs calcium and magnesium ions to a saturated state, the resin needs to be regenerated. The regeneration is to replace the calcium and magnesium ions in the resin with softening salt, so that the resin can adsorb calcium and magnesium ions again. The water softener needs to realize functions such as water supply, backwashing, salt absorption, slow washing, etc. Its internal waterway is complex, and a special soft water control valve 10 needs to be set for control.

[0054] The water softener according to the embodiment of the utility model includes a resin tank, a salt box and a soft water control valve 10. The resin tank is filled with resin, and the resin can absorb metal ions such as calcium and magnesium in the raw water to reduce the hardness of the water. The salt box is filled with brine, and the salt box is connected to the resin tank to provide brine to the resin tank, so as to clean the resin so that the resin can continue to absorb the metal ions in the raw water. The soft water control valve 10 is connected to both the resin tank and the salt box, and the soft water control valve 10 is used to control the flow direction of water. For example, the soft water control valve 10 can control the raw water to enter the resin tank for filtration to provide soft water or rinse the resin; or control the raw water to enter the salt box to dissolve the salt in the salt box to form brine.

[0055] In the utility model embodiment, refer to Figures 1 to 6 A soft water control valve 10 is proposed, which includes a valve body 100, a movable disc assembly 300, a driving assembly 400 and a position detection assembly 500. The valve body 100 is provided with at least one waterway; the movable disc assembly 300 is inserted into the valve body 100, and the movable disc assembly 300 cooperates with the corresponding waterway to define a service waterway, a salt water absorption path, a bypass waterway, a backwash waterway and a water replenishment waterway. The movable disc assembly 300 can rotate relative to the valve body 100 to control the service waterway, the salt water absorption path, the backwash waterway and the water replenishment path. , switching of the bypass waterway, the backwash waterway and the water replenishment waterway; the driving assembly 400 is connected to the moving disk assembly 300 to drive the moving disk assembly 300 to rotate; the position detection assembly 500 includes a detection switch 510 and a trigger 520, the detection switch 510 is communicatively connected to the driving assembly 400, one of the detection switch 510 and the trigger 520 is connected to the output end of the driving assembly 400, and the other is arranged on the rotation path of the detection switch 510 or the trigger 520.

[0056] At least one water channel is provided in the valve body 100, and the water channel transports water to different positions corresponding to the water softener to realize functions such as water supply, backwashing or slow washing. The moving disc assembly 300 is inserted into the valve body 100, and one end of the moving disc assembly 300 is located in the valve body 100, and the other end is located outside the valve body 100. The moving disc assembly 300 cooperates with the corresponding water channel to define a service waterway, a salt water absorption channel, a bypass waterway, a backwash waterway and a water replenishment waterway. The service waterway can transport raw water to the resin tank for filtration to obtain soft water, thereby providing raw water to users. The salt water absorption channel can provide water to mix with the salt water in the salt tank and transport it to the resin tank to clean the resin to replace the adsorbed and calcium and magnesium ions on the resin. The backwash waterway can transport raw water to the corresponding position in the resin tank to rinse the resin, remove the broken resin, and increase the gap between the resin particles, so that the resin is fully in contact with the raw water when softening the raw water, and improve the adsorption effect of calcium and magnesium ions. The water replenishment waterway can transport water (which can be raw water or softened water) to the salt box to dissolve the salt in the salt box. The bypass waterway can provide raw water. For example, when cleaning the resin, the bypass waterway can provide raw water for users to use to maintain a continuous water supply. Alternatively, users can flexibly use soft water or raw water according to their needs. For example, when flushing the toilet, the bypass waterway can provide raw water for flushing to reduce the loss of resin.

[0057] The movable disc assembly 300 is rotatable relative to the valve body 100 to control the switching of the service waterway, the salt water absorption waterway, the bypass waterway, the backwash waterway and the water replenishment waterway. According to the function to be realized, the movable disc assembly 300 is rotated to switch to the corresponding waterway so that water flows in the corresponding waterway, or the movable disc assembly 300 is rotated to adjust the opening of the corresponding waterway to control the flow rate of water in the corresponding waterway.

[0058] The drive assembly 400 is the power source of the moving disk assembly 300. The drive assembly 400 may include components such as a motor, a reducer, and a gear set, and can receive electrical signals from the control system and convert them into mechanical energy to drive the moving disk assembly 300 to rotate. The precise control capability of the drive assembly 400 enables the moving disk assembly 300 to rotate at a predetermined angle and speed, thereby achieving precise switching of the waterway. In addition, the automation characteristics of the drive assembly 400 also make the operation of the soft water control valve 10 easier and more efficient.

[0059] The position detection component 500 is a feedback system in the soft water control valve 10. It monitors the rotation position of the moving disk assembly 300 in real time through the cooperation of the detection switch 510 and the trigger 520, and feeds back the position information to the control system. The detection switch 510 is usually installed in a fixed position, while the trigger 520 is installed on the drive assembly 400 and moves with the rotation of the drive assembly 400. When the trigger 520 moves into the detection range of the detection switch 510, the detection switch 510 will generate an electrical signal, indicating that the moving disk assembly 300 has reached the predetermined position. This electrical signal is then transmitted to the control system, and the control system determines the current waterway status based on the received signal and issues the next control instruction accordingly. The presence of the position detection component 500 ensures that the soft water control valve 10 can accurately and reliably realize the switching and control of the waterway.

[0060] It should be noted that the embodiment of the present application is described by taking the trigger member 520 as an example in which the trigger member 520 can rotate with the driving assembly 400 and the detection switch 510 is fixedly arranged on the rotation path of the trigger member 520. In other embodiments, the detection switch 510 can be arranged on the driving assembly 400, and the trigger member 520 can be arranged on the rotation path of the detection switch 510. Among them, the detection switch 510 can be a micro switch or an induction switch, etc., which is not specifically limited here; the trigger member 520 can be a paddle or a spring, etc., which is not specifically limited here.

[0061] The present application sets a position detection assembly 500 between the driving assembly 400 and the moving disk assembly 300, wherein the position detection assembly 500 includes a detection switch 510 and a trigger 520, the detection switch 510 is connected to the driving assembly 400 for communication, one of the detection switch 510 and the trigger 520 is connected to the output end of the driving assembly 400, and the other is set on the rotation path of the detection switch 510 or the trigger 520. The driving assembly 400 can drive one of them to rotate. When the driving assembly 400 rotates to the point where the detection switch 510 is triggered by the trigger 520, the detection switch 510 will generate an electrical signal to transmit to the motor, and the position is recorded as the zero position or the initial position. When the soft water control valve 10 needs to switch to a different waterway, the driving assembly 400 will count from this position, and then rotate the corresponding angle to control the moving disk assembly 300 to switch to the waterway of the corresponding working condition. In this way, by cooperating with the driving component 400 and the position detection component 500, the control process of the driving disk component 300 is simplified and accurate position control is performed. At the same time, the design of the position detection component 500 makes the structure of the entire soft water valve more compact, which is beneficial to reducing the overall volume of the soft water valve and facilitating the flexible installation of the soft water valve.

[0062] Reference Figures 4 to 10According to one embodiment of the utility model, the driving component 400 includes an encoder 410 and a driving motor 420. The encoder 410 is communicatively connected to the detection switch 510 for receiving position information of the detection switch 510. The encoder 410 is communicatively connected to the driving motor 420 for controlling the rotation angle of the driving motor 420.

[0063] It is understood that the encoder 410 is a device that can convert rotational motion into a measurable electrical signal. In this embodiment, the encoder 410 is not only used to measure or sense a certain motion (such as the rotation of the drive motor 420), but more importantly, it can also convert these position information or rotation angle data into electrical signals for subsequent processing or control.

[0064] The driving motor 420 is used as a power source, and is responsible for generating a rotational force to drive the movement of the mechanical parts. In the soft water control valve 10 , the rotation of the driving motor 420 is controlled by the encoder 410 .

[0065] Specifically, in this embodiment, the encoder 410 can control the number of rotations of the drive motor 420. The moving disk assembly 300 needs to rotate one position corresponding to one working state. The rotation angle between each position is determined, and the number of rotations required by the motor of the drive motor 420 can be calculated. Then, through the counting control of the encoder 410, the drive motor 420 can be controlled to accurately rotate to the required position. However, the encoder 410 can only know how many degrees it rotates each time, and the starting position of each time is unknown, including when the soft water control valve 10 is just assembled, the initial position of the drive motor 420 is also uncertain. In this application, when the drive motor 420 drives the trigger member 520 to rotate to a specific position, the trigger member 520 will touch the detection switch 510, and the detection switch 510 will give the drive motor 420 a position signal. Therefore, the installation position of the detection switch 510 can be regarded as the zero position of the drive motor 420, that is, the drive motor 420 has a starting point for rotation, and then the encoder 410 gives the drive motor 420 how many pulse steps, and the drive motor 420 can go from this position to the position we need. The driving assembly 400 in this embodiment realizes high-precision position control and rotation angle adjustment of the moving disk assembly 300 through the coordinated work of the encoder 410 , the driving motor 420 and the detection switch 510 .

[0066] Reference Figures 4 to 10 According to an embodiment of the present invention, the driving assembly 400 further includes a gear box 430 , and the gear box 430 is connected between the output end of the driving motor 420 and the moving disk assembly 300 .

[0067] It is understandable that the drive motor 420 usually has a high speed but a relatively small torque, while the moving disc assembly 300 requires a low speed and a large torque to accurately control its position, so the gear box 430 reduces the speed and increases the torque through the internal gear transmission system to meet the driving requirements of the moving disc assembly 300. By selecting an appropriate gear ratio, the gear box 430 can ensure that the power output by the drive motor 420 is transmitted to the moving disc assembly 300 in a precise manner. It also helps to achieve precise control of the moving disc assembly 300 during rotation and ensure accurate switching of the waterway.

[0068] Reference Figures 4 to 10 According to one embodiment of the utility model, the gear box 430 includes a multi-stage gear set 431, which is meshed and connected between the drive motor 420 and the moving disk assembly 300, and the detection switch 510 or the trigger member 520 is connected to the output shaft 340 of the multi-stage gear set 431.

[0069] It is understandable that the multi-stage gear set 431 is generally composed of a plurality of gears meshing with each other, each gear having a specific number of teeth and diameter to achieve different reduction ratios. The present application uses the meshing of the multi-stage gears to realize that the high-speed and low-torque output of the drive motor 420 can be converted into the low-speed and high-torque output required by the moving disc assembly 300. The gear box 430 in the present application not only improves the efficiency of the transmission, but also makes the rotation of the moving disc assembly 300 smoother and more precise. At the same time, since the multi-stage gear set 431 can achieve a finer reduction ratio adjustment, it is easier to control the rotation angle and position of the moving disc assembly 300.

[0070] Reference Figure 1 and Figure 2 According to one embodiment of the utility model, the valve body 100 includes a first valve cavity 110 and a second valve cavity 120, both of which are connected to the waterway, and the first valve cavity 110 defines at least one of a service waterway, a brine absorption waterway, a bypass waterway, a backwash waterway and a water replenishment waterway, and the second valve cavity 120 defines the rest.

[0071] In this embodiment, the entire valve body 100 is divided into two chambers, including a first valve chamber 110 and a second valve chamber 120. The internal space and structural composition of the first valve chamber 110 and the second valve chamber 120 are basically the same, and the difference between the two chambers is that the hole structure at the bottom is different. The two chamber structures are circular structures, arranged horizontally left and right, and can also be arranged in the up and down direction, and the chamber axis 340 is horizontal. This implementation distributes the control of multiple waterways to two relatively independent chambers through the design control of the two chambers. In this way, the complexity of setting up multiple waterways in a single chamber can be reduced, the control process of waterway switching can be simplified, and the control accuracy of the moving disk assembly 300 for waterway switching can be improved.

[0072] The soft water control valve 10 may also include a bypass valve 700, a venturi 800, a water inlet pipe 130 and a water outlet pipe 140. The water inlet pipe 130 is connected to external tap water, which flows into the valve body 100 through the water inlet pipe 130. The soft water flowing out of the valve body 100 flows out through the water outlet pipe 140 for use by the user. The bypass valve 700 is used to mix with the soft water in a certain proportion to adjust the hardness of the outlet water to meet the demand for adjustable hardness of the water softener.

[0073] The soft water valve head mainly consists of four ports, namely, the water inlet 131, the water outlet 141, the sewage outlet 150 and the salt intake port 160. The salt intake port 160 is on the side of the water outlet pipe 140, and the sewage outlet 150 is on the side of the water inlet pipe 130. The soft water control valve 10 is designed with a flow meter 900, which is responsible for monitoring the amount of soft water. The flow meter 900 is installed at the position of the water outlet pipe 140 and at the front end of the bypass valve 700. The Venturi 800 module on the left side of the valve body 100 adopts a quick-insert structure design, which facilitates the rapid replacement and maintenance of the Venturi 800.

[0074] The Venturi 800 on the left side of the valve body 100 and the first valve chamber 110 and the second valve chamber 120 motor are arranged. Two channels are opened on the side of the left valve head. The bottom channel is equipped with a filter screen to filter impurities and prevent the Venturi 800 from being blocked. The upper tube is equipped with the Venturi 800, which is used to absorb salt water. The upper side of the Venturi 800 tube is equipped with a salt absorption port 160 that is vertical and upward to the tube. The salt absorption port 160 is equipped with a three-pipe adapter elbow, and the elbow outlet is facing the direction of the motor and horizontal in the working state. The salt absorption port 160 is connected to the salt box through a hose, and salt is absorbed during regeneration, and the water injection state also passes through the pipeline.

[0075] Reference Figure 3 According to an embodiment of the present invention, the number of the moving disc assemblies 300 is two, and the two moving disc assemblies 300 are correspondingly arranged in the first valve cavity 110 and the second valve cavity 120 .

[0076] It can be understood that in this embodiment, two moving disc assemblies 300 are respectively arranged in the first valve cavity 110 and the second valve cavity 120, so that the first valve cavity 110 and the second valve cavity 120 can be controlled independently without interfering with each other. This enables the system to manage multiple water flow paths at the same time, thereby improving the parallel processing capability and efficiency of the system. For complex systems that need to control multiple water flow paths at the same time, the two moving disc assemblies 300 can provide a more flexible waterway management solution. Each moving disc assembly 300 can focus on controlling the waterway in the valve cavity where it is located, thereby simplifying the design and implementation of the control system.

[0077] Specifically, the moving disc assembly 300 includes a bottom sealing ring 310, a static ceramic plate 320, a moving ceramic plate 330, a shaft 340, a shaft gasket 350, a sleeve 360, a sleeve sealing ring 370, and seals inside the shaft. The two valve chambers drive the shaft 340 to rotate through a motor, and cooperate with the ceramic plates to form water channel structures in different states to achieve different functions.

[0078] Reference Figure 2 and Figure 4 According to an embodiment of the present invention, the number of the driving components 400 and the number of the position detection components 500 are both two, and one driving component 400 corresponds to one position detection component 500 .

[0079] It can be understood that in the present embodiment, each moving disk assembly 300 is driven by an independent driving assembly 400 and monitored by a corresponding position detection assembly 500. This independent control method enables the system to respond to different work requirements more flexibly and improves the adaptability and response speed of the system. And because each moving disk assembly 300 is monitored by an independent position detection assembly 500, precise control of the position of the moving disk assembly 300 can be achieved. It helps to reduce errors and deviations and improve the control accuracy and stability of the system. At the same time, if one of the driving assemblies 400 or the position detection assembly 500 fails, the system can quickly detect and isolate the fault. Since they are configured one by one, it is easier to determine the source of the fault and repair or replace it, thereby reducing the maintenance cost of the system.
