[0088] The soft water control valve 100 of the present application is described below in conjunction with Figures 1 to 9. It is understood that the water softener absorbs metal cations such as calcium and magnesium in the raw water through the resin inside it, thereby achieving the purpose of softening the water. When the resin adsorbs calcium and magnesium ions to saturation, the resin needs to be regenerated. 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, and slow washing. Its internal water path is complex and requires a special soft water control valve to control it.

[0089] According to an embodiment of the present application, a water softener includes a resin tank, a salt tank, and a soft water control valve 100. The resin tank is filled with resin, which can adsorb metal ions such as calcium and magnesium in raw water to reduce the hardness of the water. The salt tank is filled with brine, which is connected to the resin tank to provide brine to the resin tank, thereby cleaning the resin so that the resin can continue to adsorb metal ions in the raw water. The soft water control valve 100 is connected to both the resin tank and the salt tank, and the soft water control valve 100 is used to control the flow direction of water. For example, the soft water control valve 100 can control the raw water to enter the resin tank for filtration to provide soft water or flush the resin; or control the raw water to enter the salt tank to dissolve the salt in the salt tank to form brine.

[0090] 1 and 9 , a soft water control valve 100 according to an embodiment of the present application includes a valve body 110 , a movable disc assembly 120 , a drive motor 130 , a first gear 131 , and a second gear 140 .

[0091] Specifically, at least one water channel 114 is provided in the valve body 110, and the water channel 114 transports water to different positions corresponding to the water softener to achieve functions such as water supply, backwash or slow wash. The movable disc assembly 120 is inserted into the valve body 110, with the first end of the movable disc assembly 120 located inside the valve body 110 and the second end of the movable disc assembly 120 located outside the valve body 110. The movable disc assembly 120 cooperates with the corresponding water channel 114 to define a service water channel, a brine absorption channel, a bypass water channel, a backwash water channel and a water replenishment water channel. The service water channel can transport raw water to the resin tank for filtration to obtain soft water, thereby providing the raw water to the user. The brine absorption channel can provide water to mix with the brine in the brine tank and transport it to the resin tank to clean the resin to replace the adsorbed 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 broken resin, and increase the gaps between the resin particles, so that the resin and the raw water are fully in contact when softening the raw water, thereby improving 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 tank to dissolve the salt in the salt tank. The bypass waterway can provide raw water. For example, when cleaning the resin, raw water can be provided to the user through the bypass waterway to maintain a continuous water supply. Alternatively, the user can flexibly use soft water or raw water according to demand when using it. For example, when flushing the toilet, raw water can be provided through the bypass waterway to reduce the loss of resin.

[0092] The movable disc assembly 120 rotates relative to the valve body 110 to control the switching of the service waterway, brine absorption waterway, bypass waterway, backwash waterway, and water supply waterway. Depending on the desired function, the movable disc assembly 120 is rotated to switch to the corresponding waterway 114 to allow water to flow within the corresponding waterway 114. Alternatively, the movable disc assembly 120 is rotated to adjust the opening of the corresponding waterway 114 to control the flow rate of water within the corresponding waterway.

[0093] The drive motor 130 is connected to the valve body 110 and is used to drive the movable disc assembly 120 to rotate. A first gear 131 is connected to the drive motor 130, and a second gear 140 meshes with the first gear 131. The second gear 140 is fixedly connected to the movable disc assembly 120 and fixedly connected to the second end of the movable disc assembly 120 to drive the movable disc assembly 120 to rotate relative to the valve body 110. The drive motor 130 drives the first gear 131 to rotate, which in turn drives the second gear 140 to rotate, thereby driving the movable disc assembly 120 to rotate and control the water channel 114 within the valve body 110. This simplifies the transmission structure, and by adjusting the speed or angle of rotation of the drive motor 130, the water channel 114 within the valve body 110 can be adjusted to achieve functions such as water supply, backwash, and slow wash, simplifying the control process. The transmission ratio between first gear 131 and second gear 140 is greater than 1. Specifically, the number of teeth on first gear 131 is smaller than that on second gear 140. This amplifies the torque of the motor, providing sufficient torque to resist the water pressure within waterway 114 and allowing for smoother rotation of movable disc assembly 120. Furthermore, the rotational speed of first gear 131 is greater than that of second gear 140, improving the precision of controlling the rotational angle of movable disc assembly 120 and, consequently, the control accuracy of soft water control valve 100.

[0094] According to the soft water control valve 100 of the embodiment of the present application, the first gear 131 and the second gear 140 are driven by the drive motor 130 to rotate, thereby driving the movable disc assembly 120 to rotate and adjust the water channel 114 within the valve body 110 to achieve functions such as water supply, backwash, and slow wash, thereby simplifying the transmission structure and the control process. The transmission ratio of the first gear 131 and the second gear 140 is greater than 1. The torque of the motor is amplified by the first gear 131 and the second gear 140 to provide sufficient torque to resist the pressure of the water in the water channel 114 and improve the smoothness of the movement of the movable disc assembly 120. In addition, the rotation speed of the first gear 131 is greater than the rotation speed of the second gear 140, which can improve the control accuracy of the rotation angle of the movable disc assembly 120, thereby improving the control accuracy of the soft water control valve 100.

[0095] As shown in FIG1 , according to some embodiments of the present application, the soft water control valve 100 further includes a positioning plate 150 , which is fixedly connected to the valve body 110 . For example, the positioning plate 150 can be fixed to the valve body 110 via screws. The positioning plate 150 is disposed at the second gear 140 , located on one side of the second gear 140 . A Hall effect sensor 151 is provided on the positioning plate 150 , and a magnetic member 141 is provided on the second gear 140 . When the second gear 140 rotates, the magnetic member 141 rotates with the second gear 140 and moves away from or closer to the Hall effect sensor 151 . The Hall effect sensor 151 is used to detect the position of the magnetic member 141 , thereby controlling the drive motor 130 based on the position of the magnetic member 141 to adjust the opening of the water channel 114 . As shown in FIG3 , a mounting post 145 is provided on one end surface of the second gear 140 . The mounting post 145 extends toward the positioning plate 150 , and the magnetic member 141 is embedded in the mounting post 145 .

[0096] As shown in FIG. 2 , according to some embodiments of the present application, multiple Hall sensors 151 are provided, spaced apart along the circumference of the second gear 140 . Any Hall sensor 151 and the orthographic projection of the magnetic member 141's motion trajectory on the positioning plate 150 coincide with each other, thereby improving the accuracy of the position of the magnetic member 141 . As the magnetic member 141 rotates with the second gear 140 , it can be aligned with the Hall sensor 151 at corresponding points, meaning that the orthographic projection of the magnetic member 141 on the positioning plate 150 can coincide with the Hall sensor 151 . Each Hall sensor 151 can represent a function of the water softener. When the movable disc assembly 120 rotates to switch to a corresponding water path, the magnetic member 141 moves to a position relative to the corresponding Hall sensor 151 . In this way, the drive motor 130 can be adjusted based on the position of the magnetic member 141 detected by the corresponding Hall sensor 151 , and the second gear 140 drives the movable disc assembly 120 to rotate, allowing the movable disc assembly 120 to accurately switch water paths.

[0097] For example, the resin tank has a first connecting port and a second connecting port, and one of the multiple Hall sensors 151 corresponds to the water supply function. When the magnetic part 141 moves to a position opposite to the Hall sensor 151, the corresponding water channel 114 is in an open state. At this time, the soft water control valve 100 transports raw water to the first connecting port, and the raw water enters the resin tank from the first connecting port for filtration, and the soft water flows out from the second connecting port. The soft water can be transported to the user through the soft water control valve 100 for use; or, one of the multiple Hall sensors 151 corresponds to the salt absorption function. When the magnetic part 141 moves to a position corresponding to the Hall sensor 151, the corresponding water channel 114 is in an open state, and the brine in the salt tank is transported to the second connecting port through the soft water control valve 100, and the brine enters the resin tank from the second connecting port. The brine flows through the resin to displace metal ions such as calcium and magnesium in the resin, so that the resin can continue to adsorb metal ions such as calcium and magnesium in the raw water.

[0098] As shown in FIG9 , according to some embodiments of the present application, a positioning plate 150 is stacked with the second gear 140. The positioning plate 150 is located between the second gear 140 and the valve body 110. The positioning plate 150 is provided with an escape hole 152. The movable disc assembly 120 is inserted through the escape hole 152. A plurality of Hall sensors 151 are spaced apart along the circumference of the escape hole 152. As shown in FIG1 and FIG2 , one side of the positioning plate 150 faces an end face of the second gear 140. The Hall sensor 151 is located on the side of the positioning plate 150 facing the second gear 140. The magnetic member 141 is located on the side of the second gear 140 facing the positioning plate 150. When the second gear 140 rotates, the magnetic member 141 moves in a circular motion. The plurality of Hall sensors 151 are connected in series to form a circle. The orthographic projection of the magnetic member 141 on the positioning plate 150 falls on the circular motion path formed by the plurality of Hall sensors 151 connected in series.

[0099] As shown in FIG1 , according to some embodiments of the present application, the movable disc assembly 120 includes a movable plate 121 and a rotating shaft 125. The movable plate 121 is located within the valve body 110 and at the water channel 114. A flow hole 124 is provided on the movable plate 121, and the flow hole 124 is adapted to communicate with the water channel 114. By rotating the movable plate 121 so that the flow hole 124 is aligned with the corresponding water channel 114, the corresponding water channel 114 is switched to an open state, or by adjusting the overlapping area between the flow hole 124 and the corresponding water channel 114, the opening of the corresponding water channel 114 can be adjusted. The first end of the rotating shaft 125 is connected to the movable plate 121, and the second end of the rotating shaft 125 is connected to the second gear 140. The first gear 131 drives the second gear 140 to rotate, and the second gear 140 drives the rotating shaft 125 to rotate, thereby driving the movable plate 121 to rotate to adjust the opening of the water channel 114.

[0100] According to some embodiments of the present application, the soft water control valve 100 further includes a push rod assembly connected to the valve body 110. The valve body 110 is provided with a drain port for discharging wastewater generated during the operation of the water softener. The push rod assembly is located at the drain port and is used to control the opening of the drain port. As shown in FIG3 , a push block 144 is provided on the second gear 140. The second gear 140 can drive the push block 144 to move. When the second gear 140 moves to a preset position, the push block 144 is adapted to push the push rod assembly to adjust the opening of the drain port. For example, when salt absorption is required to clean the resin in the resin tank, the drive motor 130 drives the second gear 140 to rotate to a preset position. The second gear 140 drives the movable disc assembly 120 to rotate and switch to the salt water absorption path. The push block 144 moves with the second gear 140 to a corresponding position, pushing the push rod assembly to open the drain port for wastewater discharge.

[0101] As shown in Figure 3, in some embodiments, there are two push blocks 144, and the two push blocks 144 are distributed at intervals along the circumference of the second gear 140. Therefore, the second gear 140 has two preset positions during the rotation process. At any preset position, the corresponding push block 144 pushes the push rod assembly to move to open the sewage outlet for drainage.

[0102] For example, when the movable disc assembly 120 switches the brine absorption line open, the water softener enters the brine absorption state. Brine in the brine tank is pumped into the resin tank. Raw water is then supplied through the brine absorption line, mixing with the brine to clean the resin in the tank. At this point, the second gear 140 moves to one of the preset positions, and one of the push blocks 144 pushes the push rod assembly, opening the drain port and discharging the wastewater generated during the resin cleaning process.

[0103] When the movable disc assembly 120 switches the backwash water circuit open, the water softener is in the backwash state. The backwash water circuit transports raw water to the resin tank, where the raw water cleans the resin in the resin tank, flushing away broken resin and increasing the spacing between the resins. This allows the raw water and resin to fully contact when filtering the raw water, thereby improving the adsorption capacity of calcium and magnesium ions. At this time, the second gear 140 moves to another preset position, and another push block 144 on the second gear 140 pushes the push rod assembly to move, opening the sewage outlet, allowing the sewage generated during the cleaning process to be discharged. As shown in Figure 3, in some embodiments, the angle between the two push blocks 144 and the central axis of the second gear 140 is 120 degrees, that is, the positions of the two push blocks 144 are 120 degrees apart. Correspondingly, the angle through which the movable disc assembly 120 switches from the salt water absorption circuit to the backwash water circuit can be 120 degrees.

[0104] 5 and 6 , according to some embodiments of the present application, the rotating shaft 125 includes a shaft body 129 and a connecting disc 126. The connecting disc 126 is connected to the first end of the shaft body 129, and the second end of the shaft body 129 is connected to the second gear 140. The connecting disc 126 is used to connect and fix the movable plate 121. One side of the connecting disc 126 is connected to the movable plate 121. The connecting disc 126 is provided with a first positioning portion, and the movable plate 121 is provided with a second positioning portion. The first positioning portion and the second positioning portion are connected to position the fixed plate. For example, one of the first positioning portion and the second positioning portion can be a protrusion, and the other can be a groove. The protrusion and the groove are engaged so that when the rotating shaft 125 rotates, the movable plate 121 can be driven to rotate; alternatively, one of the first positioning portion and the second positioning portion can be a through hole, and the other can be a threaded hole. The first positioning portion and the second positioning portion are connected by screws.

[0105] As shown in Figures 5 and 6 , according to some embodiments of the present application, the first positioning portion may include a positioning notch 127 and a positioning protrusion 128, and the second positioning portion may include a mating protrusion 122 and a mating groove 123. The positioning notch 127 is located at the edge of the connecting plate 126, and the positioning protrusion 128 is provided on one side of the connecting plate 126. As shown in Figures 1 and 4 , the side of the movable plate 121 facing the connecting plate 126 is provided with a mating protrusion 122 and a mating groove 123. The mating protrusion 122 is adapted to be inserted into the positioning notch 127, and the positioning protrusion 128 is adapted to be inserted into the mating groove 123, thereby circumferentially limiting the movable plate 121. The rotating shaft 125 drives the movable plate 121 to rotate, thereby adjusting the opening of the water channel 114. Both the positioning protrusion 128 and the positioning notch 127 can be multiple, with the number of mating protrusions 122 equal to the number of positioning grooves, and the number of mating grooves 123 equal to the number of positioning protrusions 128. In some embodiments, a water groove is further provided at the edge of the moving piece 121, and the water groove is connected to the circulation hole 124. After the moving piece 121 is connected to the connecting plate 126, the water on the periphery of the moving piece 121 can flow into the circulation hole 124 through the water groove. In other words, the raw water can flow from the circumference of the moving piece 121 to the circulation hole 124 and then flow into the corresponding water channel 114, thereby increasing the flow rate of the raw water.

[0106] According to some embodiments of the present application, the positioning protrusions 128 and the positioning notches 127 are irregularly distributed, so that the positioning protrusions 128 correspond one-to-one with the mating grooves 123, and the positioning notches 127 correspond one-to-one with the mating protrusions 122, so as to circumferentially position the movable plate 121 and the connecting plate 126, thereby preventing the movable plate 121 and the rotating shaft 125 from being misaligned during installation. For example, in the example of FIG4 , the flow hole 124 on the movable plate 121 is fan-shaped, and three mating grooves 123 and one mating protrusion 122 are provided at the edge of the movable plate 121. The three mating grooves 123 and one mating protrusion 122 are spaced apart along the circumference of the movable plate 121. As shown in Figure 6, three positioning protrusions 128 and one positioning notch 127 are provided on the edge of the connecting disk 126, so that during assembly, the mating protrusions 122 and the positioning notches 127 are correspondingly plugged in, and each positioning protrusion 128 and each mating groove 123 are plugged in one by one, which limits the mating position of the moving plate 121 and the connecting disk 126 in the circumferential direction.

[0107] According to some embodiments of the present application, a retaining hole 1292 is provided at the second end of the rotating shaft 125, and a retaining post 142 is provided on one side of the second gear 140. The retaining post 142 is inserted into the retaining hole 1292 and mates with the retaining post 142 to position the second gear 140, allowing the second gear 140 to drive the rotating shaft 125 to rotate. In some embodiments, the retaining hole 1292 on the rotating shaft 125 is irregular, and the cross-section of the retaining post 142 is an irregular polygonal structure. For example, in the example of FIG. 3 , the cross-section of the retaining post 142 is an irregular polygonal structure formed by a combination of a hexagon and a quadrilateral. The retaining hole 1292 on the rotating shaft 125 mates with the retaining post 142. Thus, during assembly, the retaining post 142 and the retaining hole 1292 cooperate to define the circumferential mating position of the second gear 140 and the rotating shaft 125, preventing assembly misalignment.

[0108] In this way, the circumferential mating position of the movable plate 121 and the connecting plate 126 is limited by the positioning protrusion 128, the positioning notch 127, the mating protrusion 122 and the mating groove 123; the circumferential mating position of the second gear 140 and the rotating shaft 125 is limited by the limiting column 142, thereby limiting the circumferential relative position of the magnetic component 141 and the flow hole 124. When the magnetic component 141 corresponds to the Hall sensor 151 with the corresponding function on the positioning plate 150, the flow hole 124 is opposite to the corresponding water channel 114. During the assembly process of the soft water control valve 100, there is no need to specially debug the circumferential position of the second gear 140, the rotating shaft 125 and the movable plate 121, thereby simplifying the assembly process.

[0109] According to some embodiments of the present application, a retaining rib 143 is further provided on one side of the second gear 140. The retaining rib 143 surrounds the retaining post 142, and a fixing groove is defined between the retaining rib 143 and the retaining post 142. The rotating shaft 125 is inserted into the positioning groove to improve the stability of the connection between the rotating shaft 125 and the second gear 140. As shown in Figure 3, the retaining rib 143 is annular, and the retaining post 142 is located inside the inner ring of the retaining rib 143. The inner wall of the retaining rib 143 is spaced apart from the retaining post 142. The retaining post 142 is inserted into the rotating shaft 125, and the end of the rotating shaft 125 is embedded between the retaining post 142 and the retaining rib 143, thereby firmly connecting the rotating shaft 125 to the second gear 140.

[0110] 1 and 7 , according to some embodiments of the present application, the soft water control valve 100 further includes a gland 160. The gland 160 is disposed on and connected to the valve body 110. The gland 160 and the valve body 110 may be connected by screws. The movable disc assembly 120 is disposed through the gland 160, and the second gear 140 is located on the side of the gland 160 facing away from the valve body 110. A pressure block 161 is provided on the side of the gland 160 facing the valve body 110. The pressure block 161 is adapted to be embedded in the valve body 110 and abut against the movable disc assembly 120. Specifically, the pressure block 161 abuts against the connecting disc 126 to limit the movable disc assembly 120 so that the movable disc assembly 120 is tightly connected to the waterway 114. As shown in FIG. 1 , the positioning plate 150 is located between the second gear 140 and the pressure cover 160 . A plurality of support columns are provided on the side of the pressure cover 160 facing away from the valve body 110 . The support columns are connected to the positioning plate 150 to fix the positioning plate 150 .

[0111] 7 and 8 , the valve body 110 is provided with a connecting groove 111, the opening of the water channel 114 is located on the bottom wall of the connecting groove 111 and is connected to the connecting groove 111, the movable plate 121 of the movable disc assembly 120 is located in the connecting groove 111 and is located at the connection point between the water channel 114 and the connecting groove 111. By rotating the movable plate 121, the flow hole 124 is connected to the corresponding water channel 114, so that water flows along the corresponding water channel 114 to achieve different functions. The pressure cover 160 is disposed at the opening of the connecting groove 111. The rotating shaft 125 is disposed through the pressure cover 160 and is rotatable relative to the pressure cover 160. One side of the connecting disk 126 is connected to the pressure cover 160. The pressure block 161 abuts against the other side of the connecting disk 126, thereby limiting the position of the movable plate 121 and the rotating shaft 125. The pressure block 161 can press the movable plate 121 so that the movable plate 121 fits tightly against the bottom wall of the connecting groove 111, thereby preventing water from flowing between the multiple water channels 114. As shown in Figure 1, the movable disk assembly 120 also includes a pad 1261, which is sleeved on the shaft body 129. The pad 1261 is clamped between the connecting disk 126 and the pressure block 161. The pad 1261 can rotate relative to the rotating shaft. The surface friction coefficient of the pad 1261 is smaller than the surface friction coefficient of the connecting disk 126 and the pressure block 161, so as to reduce the friction force on the connecting disk 126 during rotation.

[0112] 1 and 7 , in some embodiments, the soft water control valve 100 further includes a fixed plate 112 and a gasket 113. Both the gasket 113 and the fixed plate 112 are sandwiched between the movable plate 121 and the bottom wall of the connecting groove 111. The fixed plate 112 is in contact with the movable plate 121, and the movable plate 121 is rotatable relative to the fixed plate 112. This prevents the movable plate 121 from directly contacting and rubbing against the bottom wall of the connecting groove 111, reducing wear on the valve body 110. Furthermore, the movable plate 121 is replaceable, facilitating subsequent maintenance. The fixed plate 112 is provided with a plurality of water holes, the shape and position of which correspond to the openings of the water channel 114. Water in the water channel 114 flows sequentially through the water holes and the flow holes 124 on the movable plate 121 to the connecting groove 111. The gasket 113 is in contact with the bottom wall of the connecting groove 111 and may be an elastic member such as a silicone member. In this way, when the pressure cover 160 presses the movable plate 121 and the fixed plate 112, the gasket 113 can produce a certain deformation to play a sealing role, thereby preventing a gap between the fixed plate 112 and the bottom wall of the communicating groove 111 from causing water leakage.

[0113] As shown in FIG8 , in some embodiments, the valve body 110 is provided with a receiving groove 115, the drive motor 130 is disposed in the driving groove, the gland 160 is disposed on the receiving groove 115, and the gland 160 is provided with a connecting plate 165. The connecting plate 165 is adapted to abut against the first end of the drive motor 130, and the connecting plate 165 and the drive motor 130 can be fixedly connected by screws. The connecting plate 165 is provided with a through hole, the output shaft of the drive motor 130 is passed through the through hole, and the first gear 131 is connected to the output shaft of the drive motor 130. As shown in FIG1 , the connecting plate 165 can be located on the side of the gland 160 facing away from the valve body 110, and can extend from one side of the gland 160 to be higher than the surface of the gland 160 to accommodate the height of the drive motor 130.

[0114] As shown in Figures 5 and 7, a first sealing ring 163 is sleeved on the pressure block 161 to seal the connection between the pressure block 161 and the connecting groove 111. The rotating shaft 125 is inserted into the pressure cover 160, and the connecting plate 126 is located in the connecting groove 111. The second end of the rotating shaft 125 is located outside the valve body 110 to connect with the second gear 140. A plurality of second sealing rings 164 are sleeved on the outer peripheral wall of the shaft body 129 of the rotating shaft 125 to seal the connection between the rotating shaft 125 and the pressure cover 160. As shown in Figure 5, the shaft body 129 of the rotating shaft 125 is provided with a plurality of annular grooves 1291. The annular grooves 1291 are used to accommodate the second sealing rings 164. The depth of the annular grooves 1291 is less than the diameter of the cross section of the sealing ring. After the second sealing ring 164 is accommodated in the annular grooves 1291, the sealing ring portion protrudes out of the annular grooves 1291 to contact the pressure cover 160. In some embodiments, the soft water control valve 100 further includes a cover body 170, which is disposed on the valve body 110 and connected to the valve body 110. The first gear 131, the second gear 140 and the positioning plate 150 are all located between the valve body 110 and the cover body 170. The cover body 170 can play a role of sealing and protection.

[0115] According to some embodiments of the present application, the side of the pressure block 161 that abuts the movable disc assembly 120 is provided with multiple functional grooves that can receive water to facilitate contact between the surface of the pressure block 161 and the connecting disc 126. In some embodiments, the side of the gland 160 facing away from the valve body 110 is provided with multiple process holes corresponding to the locations of the pressure block 161. The provision of the process holes can reduce the weight of the gland 160.

[0116] 10 and 18 , the soft water control valve 100 according to an embodiment of the present application includes a valve seat 110A, a valve core assembly 120A, a driving gear 140A, and a control plate 150A.

[0117] Specifically, at least one water distribution channel 114A is provided within the valve seat 110A. The water distribution channel 114A delivers water to corresponding locations within the water softener to implement functions such as water supply, backwashing, or slow washing. A valve core assembly 120A is inserted into the valve seat 110A, with the first end of the valve core assembly 120A located within the valve seat 110A and the second end of the valve core assembly 120A located outside the valve seat 110A. The valve core assembly 120A cooperates with the corresponding water distribution channel 114A to define a service waterway, a brine absorption channel, a bypass waterway, a backwash waterway, and a water replenishment waterway. The service waterway can deliver raw water to the resin tank for filtration to obtain soft water, thereby providing the raw water to the user. The brine absorption channel can provide water that is mixed with the brine in the brine tank and delivered to the resin tank to clean the resin, thereby displacing the calcium and magnesium ions adsorbed on the resin. The backwash waterway can transport raw water to the corresponding position in the resin tank to rinse the resin, remove broken resin, and increase the gaps between the resin particles, so that the resin and the raw water are fully in contact when softening the raw water, thereby improving 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 tank to dissolve the salt in the salt tank. The bypass waterway can provide raw water. For example, when cleaning the resin, raw water can be provided to the user through the bypass waterway to maintain a continuous water supply. Alternatively, the user can flexibly use soft water or raw water according to demand when using it. For example, when flushing the toilet, raw water can be provided through the bypass waterway to reduce the loss of resin.

[0118] Valve core assembly 120A rotates relative to valve seat 110A to switch between water channels 114A, thereby controlling the switching of the service waterway, brine absorption waterway, bypass waterway, backwash waterway, and make-up waterway. Depending on the desired function, valve core assembly 120A is rotated to switch to the corresponding water channel 114A, opening the corresponding water channel 114A to allow water to flow therein. Alternatively, valve core assembly 120A is rotated to adjust the opening of the corresponding water channel 114A to control the flow of water within the corresponding waterway.

[0119] As shown in Figure 10, the control board 150A is fixedly connected to the valve seat 110A. For example, the control board 150A can be fixed to the valve seat 110A by screws. The control board 150A is located at the drive gear 140A and is located on one side of the drive gear 140A. The control board 150A is provided with a Hall sensor 151, and the drive gear 140A is provided with a magnetic member 141. When the drive gear 140A rotates, the magnetic member 141 rotates with the drive gear 140A and moves away from or closer to the Hall sensor 151. The Hall sensor 151 is used to detect the position of the magnetic member 141, thereby controlling the drive motor 130 based on the position of the magnetic member 141 to adjust the opening of the water diversion tank 114A. Thus, when switching between water diversion channels 114A, the position of magnetic element 141 is detected by Hall effect sensor 151 to determine the rotational angle of drive gear 140A, thereby controlling the rotational angle of drive gear 140A. This prevents the valve core assembly 120A from rotating improperly when switching between water diversion channels 114A, which could cause water to flow between diversion channels 114A. This improves control accuracy. Furthermore, this arrangement simplifies the structure, minimizing the space occupied by positioning piece 150 and magnetic element 141, and thus reducing the size of soft water control valve 100.

[0120] According to the soft water control valve of the embodiment of the present application, the Hall sensor 151 and the magnetic member 141 detect the angular position of the drive gear 140A to control the rotation angle of the drive gear 140A, thereby adjusting the rotation position of the valve core assembly 120A. This prevents the valve core assembly 120A from rotating improperly when switching the water diversion tanks 114A, which could cause water to flow between the diversion tanks 114A, thereby improving control accuracy. Furthermore, this arrangement simplifies the structure, and the positioning plate 150 and the magnetic member 141 occupy a small space, which helps reduce the volume of the soft water control valve 100.

[0121] As shown in Figure 12, according to some embodiments of the present application, a fixed column 145A is provided on one side end face of the driving gear 140A, and the fixed column 145A extends in the direction of the control board 150A. The magnetic part 141 is embedded in the fixed column 145A to make the magnetic part 141 close to the Hall sensor 151, thereby improving the accuracy of the Hall sensor 151 in detecting the position of the magnetic part 141.

[0122] As shown in FIG. 11 , according to some embodiments of the present application, multiple Hall sensors 151 are provided. These Hall sensors 151 are spaced apart along the circumference of the drive gear 140A. Any Hall sensor 151 coincides with the orthographic projection of the magnetic member 141's motion trajectory on the control board 150A, thereby improving the accuracy of the position of the magnetic member 141. As the magnetic member 141 rotates with the drive gear 140A, it may correspond to the Hall sensor 151 at corresponding points, meaning that the orthographic projection of the magnetic member 141 on the control board 150A may coincide with the Hall sensor 151. Each Hall sensor 151 may represent a function of the water softener. When the valve core assembly 120A rotates to switch to a corresponding water path, the magnetic member 141 moves to a position opposite the corresponding Hall sensor 151. In this way, the drive motor 130 can be adjusted based on the position of the magnetic member 141 detected by the corresponding Hall sensor 151, and the drive gear 140A drives the valve core assembly 120A to rotate, accurately switching the water path.

[0123] For example, the resin tank has a first connecting port and a second connecting port, and one of the multiple Hall sensors 151 corresponds to the water supply function. When the magnetic part 141 moves to a position opposite to the Hall sensor 151, the corresponding water diversion tank 114A is in an open state. At this time, the soft water control valve 100 transports the raw water to the first connecting port, and the raw water enters the resin tank from the first connecting port for filtration, and the soft water flows out from the second connecting port. The soft water can be transported to the user through the soft water control valve 100 for use; or, one of the multiple Hall sensors 151 corresponds to the salt absorption function. When the magnetic part 141 moves to a position corresponding to the Hall sensor 151, the corresponding water diversion tank 114A is in an open state, and the brine in the salt tank is transported to the second connecting port through the soft water control valve 100, and the brine enters the resin tank from the second connecting port. The brine flows through the resin to displace metal ions such as calcium and magnesium in the resin, so that the resin can continue to adsorb metal ions such as calcium and magnesium in the raw water.

[0124] As shown in FIG18 , according to some embodiments of the present application, a control board 150A is stacked with a drive gear 140A, with the control board 150A positioned between the drive gear 140A and the valve seat 110A. The control board 150A is provided with an axial hole 152, through which the valve core assembly 120A passes. A plurality of Hall sensors 151 are spaced apart along the circumference of the axial hole 152. As shown in FIG10 and FIG11 , one side of the control board 150A faces an end face of the drive gear 140A. The Hall sensor 151 is positioned on the side of the control board 150A facing the drive gear 140A, and the magnetic member 141 is positioned on the side of the drive gear 140A facing the control board 150A. When the drive gear 140A rotates, the magnetic member 141 moves in a circular motion. The plurality of Hall sensors 151 are connected in series to form a circular path, and the orthographic projection of the magnetic member 141 on the control board 150A falls on the circular path formed by the connection of the plurality of Hall sensors 151.

[0125] As shown in FIG10 , according to some embodiments of the present application, the soft water control valve further includes a drive motor 130 and a transmission gear 131A. The drive motor 130 is connected to the valve seat 110A and is configured to drive the valve core assembly 120A to rotate. The transmission gear 131A is connected to the drive motor 130, and the drive gear 140A meshes with the transmission gear 131A. The drive gear 140A is fixedly connected to the second end of the valve core assembly 120A to drive the valve core assembly 120A to rotate relative to the valve seat 110A. The drive motor 130 drives the transmission gear 131A to rotate, which in turn drives the drive gear 140A to rotate the valve core assembly 120A, thereby controlling the water distribution channel 114A within the valve seat 110A. This simplifies the transmission structure, and the water distribution channel 114A within the valve seat 110A can be adjusted by adjusting the speed or rotation angle of the drive motor 130 to achieve functions such as water supply, backwash, and slow wash, thereby simplifying the control process. The transmission ratio between transmission gear 131A and drive gear 140A is greater than 1. Specifically, the number of teeth on transmission gear 131A is smaller than that on drive gear 140A. This amplifies the torque of the motor, providing sufficient torque to resist the water pressure within water diversion tank 114A and allowing valve core assembly 120A to rotate more smoothly. Furthermore, the rotational speed of transmission gear 131A is greater than that of drive gear 140A, improving the precision of controlling the rotational angle of valve core assembly 120A and, consequently, the control accuracy of soft water control valve 100.

[0126] Referring to FIG. 10 , according to some embodiments of the present application, a valve core assembly 120A includes a movable plate 121 and a drive shaft 125A. The movable plate 121 is positioned within the valve seat 110A, at the water diversion groove 114A. A connecting hole 124A is defined in the movable plate 121, adapted to communicate with the corresponding water diversion groove 114A. By rotating the movable plate 121 so that the connecting hole 124A faces the corresponding water diversion groove 114A, the corresponding water diversion groove 114A is switched to an open state. Alternatively, by adjusting the overlapping area between the connecting hole 124A and the corresponding water diversion groove 114A, the opening degree of the corresponding water diversion groove 114A can be adjusted. The first end of the drive shaft 125A is connected to the movable plate 121, and the second end of the drive shaft 125A is connected to the drive gear 140A. The transmission gear 131A drives the drive gear 140A to rotate, and the drive gear 140A drives the drive shaft 125A to rotate, thereby driving the movable plate 121 to rotate to adjust the opening of the water diversion trough 114A.

[0127] According to some embodiments of the present application, the soft water control valve 100 further includes a push rod assembly connected to the valve seat 110A. The valve seat 110A is provided with a drain port for discharging wastewater generated during the operation of the water softener. The push rod assembly is located at the drain port and is used to control the opening of the drain port. As shown in FIG12 , a push plate 144A is provided on the drive gear 140A. The drive gear 140A can drive the push plate 144A to move. When the drive gear 140A moves to a predetermined position, the push plate 144A is adapted to push the push rod assembly to adjust the opening of the drain port. For example, when salt absorption is required to clean the resin in the resin tank, the drive motor 130 drives the drive gear 140A to a predetermined position. The drive gear 140A then drives the valve core assembly 120A to rotate and switch to the salt water absorption path. The push plate 144A moves in conjunction with the drive gear 140A to a corresponding position, pushing the push rod assembly to open the drain port for wastewater discharge.

[0128] As shown in Figure 12, in some embodiments, there are two push pieces 144A, and the two push pieces 144A are distributed at intervals along the circumference of the driving gear 140A. Therefore, the driving gear 140A has two preset positions during the rotation process. At any preset position, the corresponding push piece 144A pushes the push rod assembly to move to open the sewage outlet for drainage.

[0129] For example, when valve core assembly 120A switches the brine absorption line open, the water softener enters the brine absorption state. Brine in the brine tank is pumped into the resin tank. Raw water is then supplied through the brine absorption line, mixing with the brine to clean the resin in the tank. At this point, drive gear 140A moves to one of the preset positions, and one of the push pieces 144A pushes the push rod assembly, opening the drain port and discharging the wastewater generated during the resin cleaning process.

[0130] When the valve core assembly 120A switches the backwash water circuit open, the water softener is in the backwash state. The backwash water circuit is open to deliver raw water to the resin tank. The raw water cleans the resin in the resin tank, flushing away broken resin and increasing the spacing between the resins. This allows the raw water and resin to fully contact when filtering the raw water, thereby improving the adsorption capacity of calcium and magnesium ions. At this time, the drive gear 140A moves to another preset position. Another push piece 144A on the drive gear 140A pushes the push rod assembly to open the sewage outlet, allowing the sewage generated during the cleaning process to be discharged. As shown in Figure 12, in some embodiments, the angle between the two push pieces 144A and the central axis of the drive gear 140A is 120 degrees, that is, the positions of the two push pieces 144A are 120 degrees apart. Correspondingly, the angle through which the valve core assembly 120A switches from the salt water absorption circuit to the backwash water circuit can be 120 degrees.

[0131] Referring to Figures 14 and 15, according to some embodiments of the present application, the drive shaft 125A includes a main body 129A and a connecting disc 126, wherein the connecting disc 126 is connected to a first end of the main body 129A, and a second end of the main body 129A is connected to the driving gear 140A. The connecting disc 126 is used to connect and fix the movable plate 121. One side of the connecting disc 126 is connected to the movable plate 121, and a first positioning portion is provided on the connecting disc 126, and a second positioning portion is provided on the movable plate 121. The first positioning portion and the second positioning portion are connected to position the fixed plate. For example, one of the first positioning portion and the second positioning portion can be a protrusion, and the other can be a groove. The protrusion and the groove are engaged so that when the drive shaft 125A rotates, the movable plate 121 can be driven to rotate; or one of the first positioning portion and the second positioning portion can be a through hole, and the other can be a threaded hole, and the first positioning portion and the second positioning portion are connected by screws.

[0132] 14 and 15 , according to some embodiments of the present application, the first positioning portion may include a positioning notch 127 and a limiting block 128A, and the second positioning portion may include a matching block 122A and a limiting groove 123A. The positioning notch 127 is located at the edge of the connecting disk 126, and the limiting block 128A is provided on one side of the connecting disk 126. As shown in FIG10 and FIG13 , a matching block 122A and a limiting groove 123A are provided on the side of the movable plate 121 facing the connecting disk 126. The matching block 122A is adapted to be inserted into the positioning notch 127, and the limiting block 128A is adapted to be inserted into the limiting groove 123A, thereby circumferentially limiting the movable plate 121, so that the movable plate 121 can be driven to rotate by rotating the driving shaft 125A, thereby adjusting the opening of the water diversion channel 114A. There can be multiple stoppers 128A and positioning notches 127. The number of mating blocks 122A is equal to the number of positioning slots, and the number of stoppers 123A is equal to the number of stoppers 128A. In some embodiments, a water channel is further provided at the edge of the rotor 121. The water channel is connected to the communication hole 124A. After the rotor 121 is connected to the connecting plate 126, water around the rotor 121 can flow through the water channel into the communication hole 124A. In other words, raw water can flow from the circumference of the rotor 121 to the communication hole 124A and then into the corresponding water diversion groove 114A, increasing the flow rate of raw water.

[0133] According to some embodiments of the present application, the limiting blocks 128A and the positioning notches 127 are irregularly distributed, so that the limiting blocks 128A are connected to the limiting grooves 123A in a one-to-one correspondence, and the positioning notches 127 are connected to the matching blocks 122A in a one-to-one correspondence, so as to circumferentially position the movable plate 121 and the connecting disk 126, thereby preventing the movable plate 121 and the drive shaft 125A from being misaligned during installation. For example, in the example of FIG13 , the connecting hole 124A on the movable plate 121 is fan-shaped, and three limiting grooves 123A and a matching block 122A are provided at the edge of the movable plate 121. The three limiting grooves 123A and the matching block 122A are spaced apart along the circumference of the movable plate 121. As shown in Figure 15, three limit blocks 128A and a positioning notch 127 are provided at the edge of the connecting disk 126, so that during assembly, the matching block 122A and the positioning notch 127 are correspondingly plugged in, and each limit block 128A and each limit groove 123A are plugged in one by one, which limits the circumferential matching position of the movable plate 121 and the connecting disk 126.

[0134] According to some embodiments of the present application, a limiting hole 1292 is provided at the second end of the drive shaft 125A, and a connecting post 142A is provided on one side of the drive gear 140A. The connecting post 142A is inserted into the limiting hole 1292, and the connecting post 142A is adapted to the limiting hole 1292 to position the drive gear 140A so that the drive gear 140A can drive the drive shaft 125A to rotate. In some embodiments, the limiting hole 1292 on the drive shaft 125A is an irregular limiting hole 1292, and the cross-section of the connecting post 142A is an irregular polygonal structure. For example, in the example of FIG. 12 , the cross-section of the connecting post 142A can be an irregular polygonal structure formed by a combination of a hexagon and a quadrilateral, and the limiting hole 1292 on the drive shaft 125A is adapted to the connecting post 142A. Therefore, during assembly, the connection column 142A and the limiting hole 1292 can define the circumferential matching position of the drive gear 140A and the drive shaft 125A, thereby avoiding assembly misalignment.

[0135] In this way, the circumferential matching position of the movable plate 121 and the connecting disk 126 is limited by the limit block 128A, the positioning notch 127, the matching block 122A and the limiting groove 123A; the circumferential matching position of the driving gear 140A and the driving shaft 125A is limited by the connecting column 142A, thereby limiting the circumferential relative position of the magnetic component 141 and the connecting hole 124A. When the magnetic component 141 corresponds to the Hall sensor 151 with the corresponding function on the control board 150A, the connecting hole 124A is opposite to the corresponding water distribution groove 114A. During the assembly process of the soft water control valve 100, there is no need to specially debug the circumferential position of the driving gear 140A, the driving shaft 125A and the movable plate 121, thereby simplifying the assembly process.

[0136] According to some embodiments of the present application, a retaining rib 143 is further provided on one side of the drive gear 140A. The retaining rib 143 surrounds the connecting post 142A, and a fixing groove is defined between the retaining rib 143 and the connecting post 142A. The drive shaft 125A is inserted into the positioning groove to improve the stability of the connection between the drive shaft 125A and the drive gear 140A. As shown in Figure 12, the retaining rib 143 is annular, and the connecting post 142A is located inside the inner ring of the retaining rib 143. The inner wall of the retaining rib 143 is spaced apart from the connecting post 142A. The connecting post 142A is inserted into the drive shaft 125A, and the end of the drive shaft 125A is embedded between the connecting post 142A and the retaining rib 143, thereby firmly connecting the drive shaft 125A to the drive gear 140A.

[0137] 10 and 16 , according to some embodiments of the present application, the soft water control valve 100 further includes a cover 160A. The cover 160A covers and is connected to the valve seat 110A. The cover 160A and the valve seat 110A can be connected by screws. The valve core assembly 120A is inserted through the cover 160A, and the drive gear 140A is located on the side of the cover 160A facing away from the valve seat 110A. A pressure block 161 is provided on the side of the cover 160A facing the valve seat 110A. The pressure block 161 is adapted to be embedded in the valve seat 110A and abut against the valve core assembly 120A. Specifically, the pressure block 161 abuts against the connecting plate 126 to limit the position of the valve core assembly 120A, thereby tightly connecting the valve core assembly 120A to the water diversion channel 114A. As shown in FIG10 , the control board 150A is located between the driving gear 140A and the cover 160A. A plurality of support columns are provided on the side of the cover 160A facing away from the valve seat 110A. The support columns are connected to the control board 150A to fix the control board 150A.

[0138] As shown in Figures 16 and 17, the valve seat 110A is provided with a transition groove 111A, the opening of the water dividing groove 114A is located on the bottom wall of the transition groove 111A and is connected to the transition groove 111A, the movable plate 121 of the valve core assembly 120A is located in the transition groove 111A, and is located at the connection point between the water dividing groove 114A and the transition groove 111A. By rotating the movable plate 121, the connecting hole 124A is connected to the corresponding water dividing groove 114A, so that water flows along the corresponding water dividing groove 114A to achieve different functions. The cover 160A covers the opening of the transition groove 111A. The drive shaft 125A passes through the cover 160A and is rotatable relative to the cover 160A. One side of the connecting disc 126 is connected to the cover 160A. The pressure block 161 abuts against the other side of the connecting disc 126, thereby limiting the position of the movable plate 121 and the drive shaft 125A. The pressure block 161 can press the movable plate 121 tightly, so that the movable plate 121 is tightly fitted with the bottom wall of the transition groove 111A, thereby preventing water from flowing between the multiple water diversion channels 114A. As shown in Figure 10, the valve core assembly 120A also includes a partition 1261A. The partition 1261A is mounted on the main body 129A and is sandwiched between the connecting disc 126 and the pressure block 161 to separate the connecting disc 126 and the pressure block 161. The partition 1261A can rotate relative to the driving shaft 125A. The surface friction coefficient of the partition 1261A is smaller than the surface friction coefficient of the connecting disk 126 and the pressure block 161, so as to reduce the friction force on the connecting disk 126 during the rotation process.

[0139] As shown in Figures 10 and 16, in some embodiments, the soft water control valve 100 further includes a stator 112A and a gasket 113. Both the gasket 113 and the stator 112A are sandwiched between the rotor 121 and the bottom wall of the transition groove 111A. The stator 112A is in contact with the rotor 121, and the rotor 121 is rotatable relative to the stator 112A. This prevents direct contact and friction between the rotor 121 and the bottom wall of the transition groove 111A, reducing wear on the valve seat 110A. The rotor 121 is also replaceable, facilitating subsequent maintenance. The stator 112A is provided with multiple water holes, the shape and position of which correspond to the openings of the water diversion groove 114A. Water in the water diversion groove 114A flows sequentially through the water holes and the connecting holes 124A in the rotor 121 to the transition groove 111A. The gasket 113 is in contact with the bottom wall of the transition groove 111A and may be an elastic member such as a silicone rubber member. In this way, when the cover 160A presses the moving plate 121 and the stator 112A, the gasket 113 can produce a certain deformation to play a sealing role, thereby preventing a gap between the stator 112A and the bottom wall of the transition groove 111A from causing water leakage.

[0140] As shown in FIG17 , in some embodiments, a mounting groove 115A is defined on the valve seat 110A, the drive motor 130 is disposed within the drive groove, and a cover 160A is disposed over the mounting groove 115A. A fixing plate 165A is provided on the cover 160A. The fixing plate 165A is adapted to abut against a first end of the drive motor 130, and the fixing plate 165A and the drive motor 130 can be fixedly connected by screws. A through hole is defined on the fixing plate 165A, the output shaft of the drive motor 130 being passed through the through hole, and the transmission gear 131A is connected to the output shaft of the drive motor 130. As shown in FIG10 , the fixing plate 165A can be located on a side of the cover 160A facing away from the valve seat 110A, and can extend from one side of the cover 160A above the surface of the cover 160A to accommodate the height of the drive motor 130.

[0141] As shown in Figures 14 and 16, a first sealing ring 163 is sleeved on the pressure block 161 to seal the connection between the pressure block 161 and the transition groove 111A. The drive shaft 125A passes through the cover 160A, and the connecting plate 126 is located within the transition groove 111A. The second end of the drive shaft 125A is located outside the valve seat 110A to connect with the drive gear 140A. Multiple second sealing rings 164 are sleeved on the outer circumferential wall of the main body 129A of the drive shaft 125A to seal the connection between the drive shaft 125A and the cover 160A. As shown in Figure 14, the main body 129A of the drive shaft 125A is provided with multiple annular grooves 1291. The annular grooves 1291 are designed to accommodate the second sealing rings 164. The depth of the annular grooves 1291 is less than the diameter of the sealing ring's cross section. After the second sealing ring 164 is received in the annular grooves 1291, the sealing ring protrudes from the annular grooves 1291 to contact the cover 160A. In some embodiments, the soft water control valve 100 further includes a cover body 170, which covers the valve seat 110A and is connected to the valve seat 110A. The transmission gear 131A, the drive gear 140A and the control panel 150A are all located between the valve seat 110A and the cover body 170. The cover body 170 can play a role of sealing and protection.

[0142] According to some embodiments of the present application, the side of the pressure block 161 that abuts the valve core assembly 120A is provided with multiple functional grooves. The functional grooves can receive water to facilitate contact between the surface of the pressure block 161 and the connection plate 126. In some embodiments, the side of the cover 160A facing away from the valve seat 110A is provided with multiple process holes. The process holes correspond to the positions of the pressure block 161. The provision of the process holes can reduce the weight of the cover 160A.

[0143] 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.
