In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0098] The control valve and its movable disc of an embodiment of the present application are described below in conjunction with Figures 1 to 7. It is understood that the water softener adsorbs metal cations such as calcium and magnesium in the water through the resin inside it, thereby achieving the purpose of softening the water. After the resin reaches saturation, it is necessary to displace the calcium and magnesium ions on the resin with softened brine to regenerate the resin and restore its adsorption capacity. The water flowing in the water softener includes raw water, soft water, brine, sewage, etc., and the water path is complex. The control valve is used to control the flow direction of the water in the water softener.

[0099] According to an embodiment of the present application, the water softener includes a resin tank, a salt tank and a control valve 100. The resin tank is used to store resin, and the resin can adsorb metal ions such as calcium and magnesium in water to reduce the hardness of the water. The salt tank is used to store brine, and the salt tank is connected to the resin tank to provide brine to the resin tank. The brine is used to clean the resin to displace the calcium and magnesium ions adsorbed on the resin, so that the resin is reduced to continue to adsorb calcium and magnesium ions in the water. It can be understood that salt is stored in the salt tank, and "salt is seen but water is not seen" in the salt tank so that the salt in the salt tank is always kept in a saturated state, avoiding the low reduction effect on the resin caused by unsaturated brine. The control valve 100 is connected to both the resin tank and the salt tank. The control valve 100 is used to control the flow direction and flow rate of water so that water flows to the corresponding position to achieve the corresponding function. For example, the control valve 100 can control water to flow in from the inlet of the resin tank to filter the water and provide soft water; or, the control valve 100 can control water to flow in from the outlet of the resin tank to flush the resin, remove broken resin, and increase the gaps between resin particles; when the brine in the salt tank is insufficient, the control valve 100 can add water to the salt tank to dissolve the salt in the salt tank and form brine.

[0100] 1 and 2 , a control valve 100 according to an embodiment of the present application includes a valve body 110 and a movable disc 120 .

[0101] Specifically, the valve body 110 is provided with a water inlet pipe, a valve chamber 111, and at least one water channel. The valve chamber 111 is connected to the water inlet pipe, which is adapted to connect to a water source. The water channel is connected to the valve chamber 111 and is used to transport water to the resin tank or brine tank. A movable disc 120 is disposed at the junction of the valve chamber 111 and the water channel. The movable disc 120 is provided with at least one water hole 121, which connects the water channel and the valve chamber 111. Water flows into the valve chamber 111 through the water inlet pipe. Water in the valve chamber 111 then flows into the water channel through the water hole 121 for transport to the resin tank or brine tank. The movable disc 120 is rotatable relative to the valve body 110 to switch the water channel.

[0102] For example, the multiple water channels include a tank inlet channel and a water replenishment channel. The tank inlet channel is connected to the tank inlet of the resin tank, and the water replenishment channel is connected to the salt tank. When the water hole 121 is connected to the tank inlet channel, the water inlet pipe, valve cavity 111, water hole 121, and tank inlet channel collectively define a tank inlet water path. Water is transported through the tank inlet water path to the resin tank for filtration to form soft water, which is then provided to the user. When the water hole 121 is connected to the water replenishment channel, the water inlet pipe, valve cavity 111, water hole 121, and water replenishment channel collectively define a water replenishment path to replenish water to the salt tank.

[0103] Referring to Figures 3 and 4 , according to the movable disc 120 of the control valve according to an embodiment of the present application, at least one water hole 121 is provided on the movable disc 120. The water hole 121 is used to connect the valve cavity 111 and the water channel to transport the water in the valve cavity 111 to the corresponding water channel. For example, the water hole 121 penetrates the movable disc 120 in the thickness direction of the movable disc 120. The water hole 121 is used to connect the valve cavity 111 and the water channel. There can be multiple water holes 121, and the multiple water holes 121 are distributed at intervals along the circumference of the movable disc 120. By rotating the movable disc 120 to switch the water channel, the water hole 121 is connected to the corresponding water channel, so that water is transported to the corresponding position of the water softener through the water channel to achieve the corresponding function.

[0104] A water groove 122 and a water inlet 123 are provided on one side of the movable disc 120. For example, the water groove 122 and the water inlet 123 are provided on the side of the movable disc 120 facing away from the mounting surface, where the mounting surface is the surface on the control valve that contacts the movable disc 120. For example, if the movable disc 120 is located at the connection point between the valve cavity 111 and the waterway, the mounting surface is the inner wall of the valve cavity 111 where the movable disc 120 contacts the movable disc 120. As shown in Figures 2 and 3, the water groove 122 and the water inlet 123 are provided on one side of the movable disc 120 and are located within the valve cavity 111. The water inlet 123 penetrates the circumferential wall of the movable disc 120 in the radial direction of the movable disc 120 to connect with the valve cavity 111. The water groove 122 connects the water inlet 123 and the water hole 121, and water in the valve cavity 111 can flow to the water hole 121 through the water inlet 123 and the water groove 122. In this way, when water flows in the water inlet 123 and the water channel 122, it generates downward pressure (as shown in Figure 1) on the movable disc 120 to resist the upward pressure exerted on the movable disc 120 by the water in the water distribution channel 113, so that the movable disc 120 fits against the bottom wall of the valve cavity 111, thereby simplifying the connection and fixing structure of the movable disc 120, thereby simplifying the internal structure of the control valve 100, reducing the volume of the control valve 100, and reducing the cost.

[0105] A transition groove 128 is provided on the other side of the movable disc 120. The transition groove 128 is spaced apart from the water hole 121 and communicates with the transition groove 128 via the mounting surface. For example, a groove body is provided on the mounting surface, and the transition groove 128 communicates with the groove body. The movable disc 120 can be rotated to connect the water hole 121 with the groove body, thereby connecting the transition groove 128 and the water hole 121. In this way, the waterway on the other side of the movable disc 120 can be indirectly connected to the water hole 121 via the transition groove 128. The water inlet 123, the water groove 122, the water hole 121, the mounting surface, and the transition groove 128 collectively define a waterway connecting the two sides of the movable disc 120, thereby transporting water to the corresponding waterway, reducing the number of water holes 121 provided and simplifying the structure of the movable disc 120. It is understandable that when the number of water holes is too large, unexpected communication between the water holes and the water channels may easily occur during the water channel switching process, thereby requiring the addition of corresponding structures to prevent communication, and the control process of switching the water channels becomes complicated.

[0106] According to the movable disc 120 of the control valve of the embodiment of the present application, a water groove 122 and a water inlet 123 are provided on one side of the movable disc 120 to connect the valve cavity 111 with the water hole 121. Water in the valve cavity 111 can flow to the water hole 121 through the water inlet 123 and the water groove 122. In this way, when water flows in the water inlet 123 and the water groove 122, pressure is generated on the movable disc 120, causing the movable disc 120 to fit against the bottom wall of the valve cavity 111, thereby simplifying the connection and fixing structure of the movable disc 120, thereby simplifying the internal structure of the control valve 100, reducing the volume of the control valve 100, and reducing the cost. In addition, by providing a transition groove 128 on the other side of the movable disc 120, a water path connecting the two sides of the movable disc 120 is formed on the movable disc 120, simplifying the structure of the movable disc 120.

[0107] As shown in FIG3 , according to some embodiments of the present application, there are multiple water inlets 123, and the multiple water inlets 123 are evenly distributed along the circumference of the movable disc 120, so that water can be evenly directed into the corresponding waterway. It can be understood that there can be multiple water holes 121, and during operation, multiple water holes 121 can be connected to the same waterway or to different waterways; one water hole 121 can be connected to one waterway or to multiple waterways. The multiple water inlets 123 are evenly distributed along the circumference of the movable disc 120 so that water can flow evenly into the corresponding waterway. In the example of FIG3 , four water inlets 123 are provided on the movable disc 120, and the four water inlets 123 are evenly distributed along the circumference of the movable disc 120 so that water can flow evenly from multiple directions to the water holes 121 and then to the corresponding waterway. The two water inlets 123 are connected to the water through hole 121 through the water through groove 122 , and the two water inlets 123 are directly connected to the water through hole 121 .

[0108] 1 and 3 , according to some embodiments of the present application, the control valve 100 further includes a drive shaft 130 and a drive motor 140. The drive shaft 130 is in transmission connection with the drive motor 140, and the drive shaft 130 and the drive motor 140 may be connected via a transmission assembly. One end of the drive shaft 130 is connected to the movable disc 120. The drive shaft 130 is adapted to rotate the movable disc 120 to switch the water channel. The rotation angle of the movable disc 120 can be controlled to control the area of ​​the overlap between the water hole 121 and the corresponding water channel, thereby controlling the opening of the water channel.

[0109] 1 and 2 , in some embodiments, the transmission assembly includes a transmission gear 141 and a drive gear 142, wherein the transmission gear 141 and the drive gear 142 are meshed with each other. The transmission gear 141 is connected to the output shaft of the drive motor 140, and the drive gear 142 is connected to the other end of the drive shaft 130. The drive gear 142 and the drive shaft 130 can be connected via a connecting column 134, which can be a threaded column.

The transmission ratio of the transmission gear 141 to the drive gear 142 is greater than 1. The transmission gear 141 and the drive gear 142 can amplify the torque of the drive motor 140 to provide sufficient power to drive the movable plate 120 to rotate.

[0110] As shown in FIG3 , according to some embodiments of the present application, a disc-shaped connecting plate 131 is provided at one end of a drive shaft 130 and is used to connect to a movable disk 120. The diameter of the connecting plate 131 can be approximately equal to the diameter of the movable disk 120. One side of the connecting plate 131 is connected to the movable disk 120, thereby providing sufficient torque to drive the movable disk 120 to rotate. A first limiting portion is provided on the connecting plate 131, and a second limiting portion is provided on the movable disk 120. The first limiting portion and the second limiting portion are connected to circumferentially limit the movable disk 120, thereby driving the movable disk 120 to rotate by rotating the drive shaft 130.

[0111] As shown in FIG3 , according to some embodiments of the present application, the first limiting portion is a limiting protrusion 132, and the limiting portion is a limiting groove 124. The limiting protrusion 132 is embedded in the limiting groove 124 to circumferentially limit the connecting plate 131 of the movable disk 120. At least one limiting groove 124 is provided on one side of the movable disk 120, and the limiting groove 124 is used to circumferentially limit the movable disk 120. The limiting groove 124, the water inlet 123, and the water channel 122 are all located on the side of the movable disk 120 facing the connecting plate 131. There can be multiple limiting grooves 124, and the multiple limiting grooves 124 are distributed at intervals along the circumference of the movable disk 120 to ensure uniform force between the movable disk 120 and the connecting plate 131, thereby reducing the pressure on the limiting protrusion 132. In some embodiments, the limiting grooves 124 are provided at the edge of the movable disk 120 , and the plurality of limiting grooves 124 and the plurality of water inlets 123 are alternately distributed, so that the torque on the movable disk 120 can be increased to facilitate adjustment of the rotation angle of the movable disk 120 .

[0112] As shown in FIG3 , in some embodiments, the water channel 122 extends along an arc, and the end of the water channel 122 is connected to the water hole 121 to guide water to the water hole 121. A protrusion 126 is provided on the inner circle of the water channel 122, and the protrusion 126 abuts against the connecting plate 131 to provide support. As shown in FIG3 , after the movable disc 120 is connected to the drive shaft 130, the water inlet 123 and the water channel 122 define a water flow path between the rotating shaft and the movable disc 120. The water in the valve chamber 111 flows evenly to the water hole 121 through the multiple water inlets 123.

[0113] As shown in FIG3 , according to some embodiments of the present application, a positioning notch 133 is further provided on the connecting plate 131 , and a positioning block 125 is provided on one side of the movable disc 120 , with a positioning hole located on the side of the movable disc 120 facing the connecting plate 131 . The positioning block 125 mates with the positioning notch 133 , and together they position the movable disc 120 and the drive shaft 130 , preventing misalignment of the movable disc 120 and the drive shaft 130 during assembly, thereby facilitating adjustment of the relative position of the movable disc 120 and the waterway during assembly. Both the positioning notch 133 and the positioning block 125 can be one, so that the relative position of the movable disc 120 and the connecting plate 131 in the circumferential direction is uniquely determined when the movable disc 120 and the connecting plate 131 are connected. It should be noted that the number of positioning notches 133 and positioning blocks 125 is not limited herein; as long as the relative position of the movable disc 120 and the connecting plate 131 in the circumferential direction is uniquely determined when the movable disc 120 and the connecting plate 131 are connected, it suffices.

[0114] As shown in FIG2 , according to some embodiments of the present application, the control valve 100 further includes a control plate 160 , which is disposed at the drive gear 142 and can be fixedly connected to the valve body 110 . A position sensor 161 is provided on the control plate 160 , and a position marker is provided on the drive gear 142 . The position sensor 161 is used to detect the position of the position marker, thereby determining the circumferential position of the drive gear 142 based on the position of the position marker. Based on the position of the position marker, the rotation angle of the drive motor 140 is controlled to adjust the position of the movable plate 120 so that the water hole 121 is connected to the corresponding water channel. The position sensor 161 can be a Hall effect sensor, and the position marker can be a magnetic element. The control plate 160 and the drive gear 142 can be stacked, with the position sensor 161 disposed on the side of the control plate 160 facing the drive gear 142, and the position marker disposed on the side of the drive gear 142 facing the control plate 160 , to improve the detection accuracy of the position sensor 161 . During assembly, the movable disc 120 and the drive shaft 130 are circumferentially positioned by the positioning notch 133 and the positioning block 125 to avoid misalignment of the movable disc 120 and the drive shaft 130 during assembly; the driving gear 142 and the valve body 110 are circumferentially positioned by the position sensor 161 and the marking piece to position the movable disc 120 to avoid the water hole 121 from failing to communicate correctly with the corresponding water channel during operation, thereby saving the step of debugging the positions of the drive shaft 130, the movable disc 120 and the water channel.

[0115] As shown in FIG2 , in some embodiments, multiple position sensors 161 are provided, spaced apart along the circumference of the drive shaft 130 . Any position sensor 161 and the orthographic projection of the position marker's motion trajectory on the control board 160 coincide. When the position marker moves to a position opposite a position sensor 161 , the water hole 121 connects with the corresponding water channel to achieve the corresponding function. For example, if one of the multiple position sensors 161 is located at the water level, when the marker moves to a position opposite the position sensor 161 , the water hole 121 connects with the tank water channel. Water is then transported through the tank water channel to the resin tank for filtration to form soft water, which is then provided to the user.

[0116] As shown in Figures 1 and 2, according to some embodiments of the present application, the control valve 100 further includes a cover plate 150. The cover plate 150 covers the valve cavity 111 to seal the valve cavity 111, and the cover plate 150 is connected to the valve body 110. The drive shaft 130 is disposed through the cover plate 150 and is rotatable relative to the cover plate 150. A second sealing ring 154 is sleeved on the cover drive shaft 130 to seal the connection between the drive shaft 130 and the plate. As shown in Figure 1, in some embodiments, a pressure block 151 is provided on the side of the cover plate 150 facing the valve body 110. The pressure block 151 is located in the valve cavity 111. A first sealing ring 153 is sleeved on the outer circumference of the pressure block 151. The first sealing ring 153 is used to seal the connection between the pressure block 151 and the inner wall of the valve cavity 111. The pressure block 151 abuts against the connecting plate 131 to limit the drive shaft 130 in the axial direction. The drive shaft 130 may be sleeved with a partition 135 , which is sandwiched between the connecting plate 131 and the pressure block 151 to separate the connecting plate 131 and the pressure block 151 . The surface friction coefficient of the partition 135 is low to reduce the friction force on the connecting plate 131 during rotation.

[0117] As shown in FIG6 , the valve body 110 is provided with a mounting groove 116, and the drive motor 140 is received in the mounting groove 116. As shown in FIG2 , the cover plate 150 is provided with a fixing plate 152, which covers the mounting groove 116. The fixing plate 152 abuts against and is connected to one end of the drive motor 140 to fix the drive motor 140. The fixing plate 152 is provided with a through hole, and the output shaft of the drive motor 140 is passed through the through hole to be connected to the transmission gear 141. The control valve 100 may further include a cover 170, which is provided over the valve body 110. A storage space is formed between the cover 170 and the valve body 110, and the drive motor 140, the transmission gear 141, the drive gear 142, the drive shaft 130, and the control panel 160 are all located in the storage space.

[0118] As shown in Figures 1 and 6 , according to some embodiments of the present application, at least one water diversion groove 113 is provided on the bottom wall of the valve cavity 111. The water diversion groove 113 connects the waterway and the valve cavity 111, and a movable disc 120 is provided on the bottom wall of the valve cavity 111. Rotating the movable disc 120 connects the water holes 121 with the corresponding water diversion grooves 113, thereby allowing water in the valve cavity 111 to flow into the corresponding waterway through the water holes 121 and the water diversion grooves 113. There may be multiple water diversion grooves 113, and the multiple water diversion grooves 113 may be distributed at intervals along the circumference of the valve cavity 111.

[0119] As shown in FIG6 , according to some embodiments of the present application, a valve seat 119 is provided on the bottom wall of the valve cavity 111, a water diversion groove 113 is provided on the valve seat 119, and a movable disc 120 is provided on the top surface of the valve seat 119, with the top surface of the valve seat 119 serving as the mounting surface. Multiple water diversion grooves 113 are spaced apart along the circumference of the valve seat 119. By rotating the movable disc 120, the water holes 121 are connected to the corresponding water diversion grooves 113, thereby connecting the valve cavity 111 and the waterway. The cross-section of the water diversion groove 113 can be fan-shaped to improve the utilization rate of the surface area of ​​the valve seat 119, maximize the cross-sectional area of ​​the water diversion groove 113, and increase the water inlet speed of the waterway. In some embodiments, the diameter of the valve seat 119 is smaller than the diameter of the valve cavity 111. The circumferential wall of the valve seat 119 and the inner wall of the valve cavity 111 jointly define the water inlet groove 112, which connects the water inlet pipe and the valve cavity 111. It is understandable that the diameter of the movable disc 120 is smaller than the diameter of the valve cavity 111 so that the water inlet groove 112 remains in communication with the valve cavity 111 .

[0120] As shown in FIG7 , according to some embodiments of the present application, the end face of the valve seat 119 is divided into six sector-shaped areas along the circumferential direction, and each sector-shaped area has an inner area and an outer area along the radial direction. The inner area is closer to the middle of the valve seat 119 relative to the outer area. Both the inner area and the outer area are provided with sub-grooves, that is, the sub-grooves are distributed along the circumference and radial direction of the valve seat 119, and some of the sub-grooves are connected to define the water diversion groove 113. This can improve the utilization rate of the valve seat 119, maximize the volume of the water diversion groove 113, and increase the flow rate of water. As shown in FIG4 , in some embodiments, the water holes 121 are all sector-shaped, and the central angle of the sector-shaped water holes 121 is 60 degrees to match the water diversion groove 113.

[0121] As shown in FIG7 , in some embodiments, in a counterclockwise direction, the six sector-shaped areas are, in order, the first sector I, the second sector II, the third sector III, the fourth sector IV, the fifth sector V, and the sixth sector VI. The sub-grooves in the inner area of ​​the first sector I and the sub-grooves in the outer area, as well as the sub-grooves in the outer area of ​​the second sector II, are connected to define a balancing groove 118. The balancing groove 118 is connected to the water inlet groove 112, and water in the water inlet groove 112 can flow into the balancing groove 118. A water hole can be provided on the side wall of the valve seat 119 corresponding to the first sector I or the second sector II to connect the balancing groove 118 and the water inlet groove 112. In addition, the balancing groove 118 is connected to the valve cavity 111 through the movable disk 120. By rotating the movable disk 120, the water hole 121 is aligned with the balancing groove 118 to connect the balancing groove 118 and the valve cavity 111. In this way, the water in the valve chamber 111 has a downward pressure on the movable disc 120 (in the direction shown in Figure 1), so that the movable disc 120 remains in contact with the valve seat 119; the water in the balancing groove 118 has an upward pressure on the movable disc 120 (in the direction shown in Figure 1) to balance part of the downward pressure and reduce the friction force exerted on the movable disc 120 during the rotation process, so as to facilitate the adjustment of the rotation angle of the movable disc 120.

[0122] In the example of Figure 5, the sub-troughs in the inner area of ​​the fifth sector V are connected to the sub-troughs in the outer area to define the tank inlet and outlet troughs, which are connected to the tank inlet of the resin tank through the inlet water channel; the sub-troughs in the inner area of ​​the fourth sector IV define the water replenishment trough, which is connected to the salt box through the water replenishment water channel; the sub-troughs in the inner area of ​​the third sector III are connected to the sub-troughs in the outer area to define the bypass water distribution trough 113, and a water outlet pipe is provided on the valve seat 119, and the bypass water distribution trough 113 is connected to the water outlet pipe.

[0123] In this way, when it is necessary to soften the water, the movable disk 120 is rotated so that one of the water holes 121 is connected to the tank inlet trough, and the other water hole 121 is connected to the balancing tank 118. Water flows from the water inlet pipe to the water inlet trough 112. Part of the water in the water inlet trough 112 flows to the valve cavity 111, and flows to the tank inlet trough through the water hole 121 connected to the tank inlet trough, and then flows to the tank inlet port of the resin tank; another part of the water in the water inlet trough 112 flows to the balancing tank 118, and flows into the valve cavity 111 through the water hole 121 connected to the balancing tank 118, and then flows into the tank inlet trough through the water hole 121 connected to the tank inlet trough, and finally flows to the tank inlet port of the resin tank. When the user needs to use water, for example, when flushing the toilet, the movable disc 120 is rotated so that the water hole 121 is connected to the bypass water distribution tank 113 and the balancing tank 118. Part of the water in the water inlet tank 112 flows to the bypass water distribution tank 113 through the valve cavity 111 and the water hole 121, and another part of the water in the water inlet tank 112 flows to the bypass water distribution tank 113 through the balancing tank 118 and the water hole 121, and finally flows out through the outlet pipe to be provided to the user.

[0124] According to some embodiments of the present application, at least one water barrier 127 is provided on the other side of the movable disc 120. This barrier rib 127 can isolate the water diversion channels 113 and prevent water from flowing between the diversion channels 113. As shown in FIG4 , the side of the movable disc 120 facing the valve seat 119 is provided with multiple water barrier ribs 127. The water barrier ribs 127 conform to the surface of the valve seat 119 to prevent water from flowing between the diversion channels 113. As shown in FIG4 or 7 , the water barrier ribs 127 define a transition groove 128. For example, the transition groove 128 extends radially along the movable disc 120. One end of the transition groove 128 is circular and located at the center of the movable disc 120, while the other end of the transition groove 128 is fan-shaped. As shown in FIG5 , a central groove is provided at the center of the valve seat 119. The central groove communicates with the inner sub-grooves of the sixth sector VI to define a water flow channel 1191. During rotation of the movable disc 120, one end of the transition groove 128 remains connected to the central groove. In this way, rotating the movable disc 120 to a certain angle allows the water channel 1191 to communicate with the water hole 121. Furthermore, for example, the transition groove 128 communicates with the water hole 121 through the water channel 1191. The other end of the transition groove 128 communicates with the corresponding water diversion groove 113. The transition groove 128 and the water channel 1191 can transfer water to the corresponding water diversion groove 113, thereby reducing the number of water diversion holes 121 and simplifying the control process.

[0125] For example, in the example of FIG5 , the sub-troughs in the inner area of ​​the fourth sector IV define a water replenishment trough, which is connected to the brine tank to replenish water. The sub-troughs in the outer area of ​​the fourth sector IV define a backwash water distribution trough 113, which is connected to the outlet of the resin tank. Backwash water distribution trough 113 can be used to backwash the resin in the resin tank to flush out broken resin and increase the gaps between the resin tanks. By rotating the movable disk 120, one of the water holes 121 is connected to the portion of the water channel 1191 located in the sixth sector VI, and the other end of the transition channel 128 is connected to the water replenishment trough. As a result, water in the valve chamber 111 can flow through the water hole 121 into the water channel 1191, then through the transition channel 128 into the water replenishment trough, and finally into the brine tank to replenish water. Through the cooperation of the transition groove 128 and the water hole 121, the water in the valve cavity 111 is transported to the corresponding water distribution groove 113, and then transported to the corresponding position on the water softener through the corresponding water channel to achieve multiple functions.

[0126] 1 and 2 , according to some embodiments of the present application, the control valve 100 further includes a fixed disk 114, which is sandwiched between the movable disk 120 and the bottom wall of the valve chamber 111. The fixed disk 114 is provided with at least one communication hole, which is connected to the corresponding water diversion groove 113. The number of communication holes is the same as the number of water diversion grooves 113, and each communication hole is connected to each water diversion groove 113 on a one-to-one basis. The fixed disk 114 can separate the movable disk 120 from the valve seat 119, thereby preventing wear caused by contact and friction between the valve seat 119 and the movable disk 120, thereby extending the service life of the valve body 110. The fixed disk 114 is also easily replaceable, and the subsequent maintenance cost is low. In some embodiments, the control valve 100 further includes a gasket 115, which is sandwiched between the fixed disc 114 and the bottom wall of the valve cavity 111, that is, between the fixed disc 114 and the valve seat 119. The gasket 115 is a deformable component. During assembly, the movable disc 120 compresses the gasket 115, causing it to deform and seal the connection between the movable disc and the water diversion groove 113, thereby preventing water from leaking between the water diversion grooves 113. As shown in FIG6 , a receiving groove 117 is provided on the bottom wall of the valve cavity 111. The end surface of the valve seat 119 is provided with at least one rib, which is arranged around the opening of the water diversion groove 113. The end surface of the valve seat 119 and the multiple ribs together define the receiving groove 117. The gasket 115 is adapted to be received within the receiving groove 117.
