[0049] The following will be described in conjunction with Figures 1 to 7 The control valve and its moving disc of the embodiments of the present application are described. It can be understood that the water softener absorbs metal cations such as calcium and magnesium in water through the resin inside it, so as to achieve the purpose of softening water. After the resin reaches saturation, the calcium and magnesium ions on the resin need to be replaced by salt water to regenerate the resin and restore the adsorption capacity. The water flowing in the water softener includes raw water, soft water, salt water, sewage, etc., and the waterway is complex. The control valve is used to control the water flow direction in the water softener.

[0050] According to the softener of the embodiment of the present application, the resin tank is used for containing resin, the resin can adsorb metal ions such as calcium and magnesium in water to reduce the hardness of water. The salt tank is used for containing brine, the salt tank is communicated with the resin tank to provide brine to the resin tank. The brine is used for cleaning the resin to replace the calcium and magnesium ions adsorbed on the resin, so that the resin is reduced to continue to adsorb calcium and magnesium ions in water. The control valve 100 is communicated with the resin tank and the salt tank, and the control valve 100 is used for controlling the flow direction and flow of water to flow to the corresponding position to realize the corresponding function. For example, the control valve 100 can control water to flow from the inlet of the resin tank to filter water to provide soft water; or the control valve 100 can control water to flow from the outlet of the resin tank to flush the resin to remove broken resin and increase the gap between resin particles; when the brine in the salt tank is insufficient, the control valve 100 can supplement water to the salt tank to dissolve the salt in the salt tank to form brine.

[0051] Referring to Figure 1 and Figure 2 As shown in the figure, the control valve 100 of the embodiment of the present application comprises a valve body 110 and a moving disc 120.

[0052] Specifically, the valve body 110 is provided with a water inlet pipe, a valve cavity 111 and at least one water channel, the valve cavity 111 is communicated with the water inlet pipe, the water inlet pipe is suitable for being communicated with a water source, the water channel is communicated with the valve cavity 111, and the water channel is used for conveying water into the resin tank or the salt tank. The moving disc 120 is attached to the valve cavity 111 at the communicated position of the valve cavity 111 and the water channel, the moving disc 120 is provided with at least one water passing hole 121, the water passing hole 121 is used for communicating the water channel and the valve cavity 111, water flows into the valve cavity 111 through the water inlet pipe, and the water in the valve cavity 111 can flow into the water channel through the water passing hole 121 to be conveyed into the resin tank or the salt tank. The moving disc 120 is rotatable relative to the valve body 110 to switch the water channel.

[0053] For example, the plurality of water channels comprises a tank inlet water channel and a water supplement water channel, the tank inlet water channel is communicated with the tank inlet of the resin tank, and the water supplement water channel is communicated with the salt tank. When the water passing hole 121 is communicated with the tank inlet water channel, the water inlet pipe, the valve cavity 111, the water passing hole 121 and the tank inlet water channel jointly define a tank inlet water path, and water is conveyed into the resin tank through the tank inlet water path to be filtered to form soft water to be provided to the user; when the water passing hole 121 is communicated with the water supplement water channel, the water inlet pipe, the valve cavity 111, the water passing hole 121 and the water supplement water channel jointly define a water supplement water path to supplement water to the salt tank.

[0054] Referring to Figure 3 and Figure 4As shown, the moving disc 120 of the control valve according to the embodiment of the present application is provided with at least one water passage hole 121 penetrating the moving disc 120 in the thickness direction of the moving disc 120, and the water passage hole 121 is used to connect the valve cavity 111 and the water channel, so as to deliver the water in the valve cavity 111 to the corresponding water channel. The water passage hole 121 can be multiple, and the multiple water passage holes 121 are distributed along the circumference of the moving disc 120. By rotating the moving disc 120 to switch the water channel, the water passage hole 121 is connected with the corresponding water channel, so as to deliver the water to the corresponding position of the water softener through the water channel, and the corresponding function is realized.

[0055] The side of the moving disc 120 away from the mounting surface is provided with a water passage groove 122 and a water inlet 123, wherein the mounting surface is the surface of the control valve which is attached to the moving disc 120, for example, the moving disc 120 is attached to the inner wall of the valve cavity 111 at the position where the valve cavity 111 is connected with the water channel, and the mounting surface is the inner wall of the valve cavity 111 which is attached to the moving disc 120. As shown in the figure, Figure 2 As shown in the figure, Figure 3 As shown, the water passage groove 122 and the water inlet 123 are arranged on one side of the moving disc 120 and located in the valve cavity 111, and the water inlet 123 penetrates the peripheral wall of the moving disc 120 in the radial direction of the moving disc 120, so as to be connected with the valve cavity 111. The water passage groove 122 connects the water inlet 123 and the water passage hole 121, and the water in the valve cavity 111 can flow to the water passage hole 121 through the water inlet 123 and the water passage groove 122. In this way, when the water flows in the water inlet 123 and the water passage groove 122, the pressure of the water in the direction downward (as shown in the figure) is generated on the moving disc 120, so as to resist the upward pressure of the water in the water distribution groove 113 on the moving disc 120, and the moving disc 120 is attached to the bottom wall of the valve cavity 111, thereby simplifying the connection and fixing structure of the moving disc 120, simplifying the internal structure of the control valve 100, reducing the volume of the control valve 100, and reducing the cost. Figure 1 The other side of the moving disc 120 is provided with a transition groove 128, and the transition groove 128 is spaced apart from the water passage hole 121 and connected with the water passage hole 121 through the mounting surface. For example, the mounting surface is provided with a groove body, and the transition groove 128 is connected with the groove body, and the moving disc 120 can be rotated to make the water passage hole 121 connected with the groove body, so as to be connected with the transition groove 128 and the water passage hole 121. In this way, the water channel and the water passage hole 121 can be indirectly connected through the transition groove 128 on the other side of the moving disc 120, and the water inlet 123, the water passage groove 122, the water passage hole 121, the mounting surface and the transition groove 128 jointly define a water path connecting the two sides of the moving disc 120, so as to deliver the water to the corresponding water channel, reduce the number of water passage holes 121, and simplify the structure of the moving disc 120. It can be understood that when the number of water passage holes is too large, the unintended connection between the water passage hole and the water channel is prone to occur during the switching of the water channel, and accordingly, the structure for preventing the connection needs to be increased, and the control process of switching the water channel is complicated.

[0056] ​

[0057] According to an embodiment of the present invention, the movable disc 120 of the control valve is provided with a water channel 122 and a water inlet 123 on one side of the movable disc 120 to connect the valve chamber 111 and the water passage 121. Water in the valve chamber 111 can flow to the water passage 121 through the water inlet 123 and the water channel 122. Thus, when water flows in the water inlet 123 and the water channel 122, it exerts pressure on the movable disc 120, causing the movable disc 120 to adhere to the bottom wall of the valve chamber 111. This simplifies 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 lowering the cost. Furthermore, by providing a transition groove 128 on the other side of the movable disc 120, a water passage connecting its two sides is formed on the movable disc 120, further simplifying the structure of the movable disc 120.

[0058] See Figure 3 As shown, according to some embodiments of the present invention, there are multiple water inlets 123, which are evenly distributed along the circumference of the moving plate 120, thus guiding water evenly into the corresponding water channels. It is understood that there can be multiple water passages 121. During operation, multiple water passages 121 can communicate with the same water channel or with different water channels; one water passage 121 can communicate with one water channel or with multiple water channels. The multiple water inlets 123 are evenly distributed along the circumference of the moving plate 120 to ensure that water flows evenly into the corresponding water channels. Figure 3 In the example, the moving plate 120 is provided with four water inlets 123, which are evenly distributed along the circumference of the moving plate 120 so that water flows evenly from multiple directions to the water passage 121 and then into the corresponding water channel. Two of the water inlets 123 are connected to the water passage 121 through the water passage groove 122, and the other two water inlets 123 are directly connected to the water passage 121.

[0059] See Figure 1 and Figure 3 As shown, according to some embodiments of the present invention, the control valve 100 further includes a drive shaft 130 and a drive motor 140. The drive shaft 130 and the drive motor 140 are connected in a transmission manner, and the drive shaft 130 and the drive motor 140 can be connected by a transmission assembly. One end of the drive shaft 130 is connected to a movable disc 120. The drive shaft 130 is adapted to drive the movable disc 120 to rotate, thereby switching water channels. The rotation angle of the movable disc 120 can be controlled to control the area of ​​the overlapping portion of the water passage 121 and the corresponding water channel, thereby controlling the opening degree of the water channel.

[0060] See Figure 1 and Figure 2As shown, in some embodiments, the transmission assembly comprises a transmission gear 141 and a driving gear 142, wherein the transmission gear 141 and the driving gear 142 are engaged, the transmission gear 141 is connected with the output shaft of the driving motor 140, and the driving gear 142 is connected with the other end of the driving shaft 130. The driving gear 142 and the driving shaft 130 can be connected through a connecting column 134, which can be a threaded column. The driving gear 142 is driven to rotate by the transmission gear 141, and in turn drives the driving shaft 130 and the dynamic disc 120 to rotate. The transmission ratio of the driving gear 142 of the transmission gear 141 is greater than 1, and the transmission gear 141 and the driving gear 142 can amplify the torque of the driving motor 140 to provide sufficient power to drive the dynamic disc 120 to rotate.

[0061] Referring to Figure 3 As shown, according to some embodiments of the present application, one end of the driving shaft 130 is provided with a connecting plate 131, which is disc-shaped, and the connecting plate 131 is used to connect the dynamic disc 120. The diameter of the connecting plate 131 can be approximately equal to the diameter of the dynamic disc 120, and one side of the connecting plate 131 is connected with the dynamic disc 120, which can provide sufficient torque to drive the dynamic disc 120 to rotate. The connecting plate 131 is provided with a first limiting portion, and the dynamic disc 120 is provided with a second limiting portion. The first limiting portion is connected with the second limiting portion to limit the dynamic disc 120 in the circumferential direction, so that the dynamic disc 120 can be driven to rotate by rotating the driving shaft 130.

[0062] As Figure 3 As shown, 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 limit the connecting plate 131 of the dynamic disc 120 in the circumferential direction. One side of the dynamic disc 120 is provided with at least one limiting groove 124, which is used to limit the dynamic disc 120 in the circumferential direction. The limiting groove 124, the water inlet 123 and the water passage groove 122 are all located on the side of the dynamic disc 120 facing the connecting plate 131. The limiting groove 124 can be multiple, and the multiple limiting grooves 124 are distributed along the circumferential direction of the dynamic disc 120 to make the force between the dynamic disc 120 and the connecting plate 131 uniform and reduce the pressure on the limiting protrusion 132. In some embodiments, the limiting groove 124 is arranged at the edge of the dynamic disc 120, and the multiple limiting grooves 124 and the multiple water inlets 123 are alternately distributed, which can increase the torque on the dynamic disc 120 to facilitate the adjustment of the rotation angle of the dynamic disc 120.

[0063] As Figure 3 As shown, in some embodiments, the water passage groove 122 extends along an arc, and the end of the water passage groove 122 communicates with the water passage hole 121 to guide water to the water passage hole 121. The inner ring of the water passage groove 122 is provided with a lug 126, which abuts against the connecting plate 131 to serve as a support. Figure 3As shown, after the moving disc 120 is connected to the drive shaft 130, the water inlet 123 and the water channel 122 define the water flow path between the rotating shaft and the moving disc 120. The water in the valve chamber 111 flows evenly to the water passage 121 through multiple water inlets 123.

[0064] like Figure 3 As shown, according to some embodiments of the present invention, the connecting plate 131 is further provided with a positioning notch 133, and a positioning block 125 is provided on one side of the moving plate 120. The positioning hole is located on the side of the moving plate 120 facing the connecting plate 131. The positioning block 125 is adapted to the positioning notch 133, and the positioning block 125 and the positioning notch 133 together position the moving plate 120 and the drive shaft 130 to avoid misalignment of the moving plate 120 and the drive shaft 130 during the assembly process, thereby facilitating the adjustment of the relative position of the moving plate 120 and the waterway during assembly. There can be only one positioning notch 133 and one positioning block 125, so that the relative position of the moving plate 120 and the connecting plate 131 in the circumferential direction is uniquely determined when they are connected. It should be noted that the number of positioning notches 133 and positioning blocks 125 is not limited here, as long as the relative position of the moving plate 120 and the connecting plate 131 in the circumferential direction is uniquely determined when they are connected.

[0065] See Figure 2 As shown, according to some embodiments of the present invention, 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 positioning element is provided on the drive gear 142. The position sensor 161 is used to detect the position of the positioning element to determine the circumferential position of the drive gear 142, and to control the rotation angle of the drive motor 140 based on the position of the positioning element, thereby adjusting the position of the moving disc 120 so that the water passage 121 communicates with the corresponding water channel. The position sensor 161 can be a Hall sensor, and the positioning element 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 positioning element 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 moving plate 120 and the drive shaft 130 are circumferentially positioned by the positioning notch 133 and the positioning block 125 to avoid misalignment of the moving plate 120 and the drive shaft 130 during assembly; the drive gear 142 and the valve body 110 are circumferentially positioned by the position sensor 161 and the positioning component to position the moving plate 120, so as to avoid the water passage 121 not being properly connected to the corresponding water channel during operation, thus saving the step of adjusting the position of the drive shaft 130, the moving plate 120 and the water channel.

[0066] like Figure 2As shown, in some embodiments, the position sensor 161 is multiple, and the multiple position sensors 161 are spaced along the circumference of the drive shaft 130, and any one position sensor 161 is coincident with the orthographic projection of the movement trajectory of the marker on the control board 160, when the marker moves to the position opposite to the position sensor 161, the water hole 121 is communicated with the corresponding water channel to realize the corresponding function. For example, one of the multiple position sensors 161 is located at the water making position, when the marker moves to the position opposite to the position sensor 161, the water hole 121 is communicated with the tank filling water channel, the tank filling water channel is communicated, and water is transported to the resin tank through the tank filling water channel for filtration to form soft water, thereby providing for the user.

[0067] As shown, Figure 1 With Figure 2 As shown, according to some embodiments of the application, the control valve 100 further comprises 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 with the valve body 110. The drive shaft 130 penetrates the cover plate 150 and is rotatable relative to the cover plate 150, and a second sealing ring 154 is sleeved on the drive shaft 130 to seal the connection between the drive shaft 130 and the plate. As shown, Figure 1 As shown, in some embodiments, the side of the cover plate 150 facing the valve body 110 is provided with a pressing block 151, the pressing block 151 is located in the valve cavity 111, and a first sealing ring 153 is sleeved on the outer circumferential surface of the pressing block 151, the first sealing ring 153 is used to seal the connection between the pressing block 151 and the inner wall of the valve cavity 111. The pressing block 151 abuts against the connecting plate 131 to limit the drive shaft 130 in the axial direction. The drive shaft 130 can be sleeved with a partition plate 135, the partition plate 135 is clamped between the connecting plate 131 and the pressing block 151 to space apart the connecting plate 131 and the pressing block 151, and the surface of the partition plate 135 has a low friction coefficient to reduce the friction force suffered by the connecting plate 131 during rotation.

[0068] As shown, Figure 6 As shown, 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, Figure 2 As shown, the cover plate 150 is provided with a fixing plate 152, the fixing plate 152 covers the mounting groove 116, and the fixing plate 152 abuts against and is connected with 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 penetrates the through hole to be connected with the transmission gear 141. The control valve 100 can further comprise a cover body 170, the cover body 170 covers the valve body 110, and a receiving space is formed between the cover body 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 board 160 are all located in the receiving space.

[0069] As shown, Figure 1and Figure 6 As shown, according to some embodiments of the present invention, at least one water distribution groove 113 is provided on the bottom wall of the valve cavity 111. The water distribution groove 113 connects the water channel and the valve cavity 111, and the movable disk 120 is attached to the bottom wall of the valve cavity 111. By rotating the movable disk 120, the water passage hole 121 is connected to the corresponding water distribution groove 113, so that water in the valve cavity 111 flows into the corresponding water channel through the water passage hole 121 and the water distribution groove 113. There can be multiple water distribution grooves 113, and the multiple water distribution grooves 113 can be distributed at intervals along the circumferential direction of the valve cavity 111.

[0070] like Figure 6 As shown, according to some embodiments of the present invention, the bottom wall of the valve cavity 111 is provided with a valve seat 119, a water distribution groove 113 is provided on the valve seat 119, and a movable disk 120 is attached to the top surface of the valve seat 119, the top surface of the valve seat 119 being the mounting surface. Multiple water distribution grooves 113 are spaced apart along the circumferential direction of the valve seat 119. By rotating the movable disk 120, the water passage hole 121 is connected to the corresponding water distribution groove 113, thereby connecting the valve cavity 111 and the water channel. The cross-section of the water distribution groove 113 can be fan-shaped to improve the utilization rate of the surface area of ​​the valve seat 119, maximizing the cross-sectional area of ​​the water distribution groove 113 and increasing the water inlet speed of the water channel. In some embodiments, the diameter of the valve seat 119 is smaller than the diameter of the valve cavity 111, and the peripheral wall of the valve seat 119 and the inner wall of the valve cavity 111 together define an inlet groove 112, which connects the inlet pipe and the valve cavity 111. It is understandable that the diameter of the moving plate 120 is smaller than the diameter of the valve chamber 111 so that the water inlet 112 remains in communication with the valve chamber 111.

[0071] like Figure 7 As shown, according to some embodiments of the present invention, the end face of the valve seat 119 is divided into six sector-shaped areas along the circumferential direction. Each sector-shaped area has an inner area and an outer area along the radial direction. The inner area is closer to the center of the valve seat 119 than the outer area. Both the inner and outer areas are provided with sub-grooves, that is, the sub-grooves are distributed along the circumferential and radial directions of the valve seat 119. Some of the sub-grooves are connected to define the water distribution groove 113. This can improve the utilization rate of the valve seat 119 and maximize the volume of the water distribution groove 113 to increase the water flow rate. Figure 4 As shown, in some embodiments, the water passage holes 121 are all fan-shaped, and the central angle of the fan-shaped water passage holes 121 is 60 degrees, so as to match the water distribution tank 113.

[0072] See Figure 7As shown, in some embodiments, in the counterclockwise direction, the six sectors are sequentially 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 of the inner region and the outer region of the first sector I and the sub-grooves of the outer region of the second sector II are communicated to define a balance groove 118, which is communicated with the water inlet groove 112. Water in the water inlet groove 112 can flow into the balance groove 118. A water passing 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 communicate the balance groove 118 and the water inlet groove 112. Further, the balance groove 118 is communicated with the valve cavity 111 through the driving disc 120. The water passing hole 121 is communicated with the balance groove 118 by rotating the driving disc 120 to communicate the balance groove 118 and the valve cavity 111. In this way, water in the valve cavity 111 has a downward pressure (as shown by the arrow in the figure) on the driving disc 120, so that the driving disc 120 is kept in close contact with the valve seat 119. Water in the balance groove 118 has an upward pressure (as shown by the arrow in the figure) on the driving disc 120 to balance the part of the downward pressure, so as to reduce the friction force on the driving disc 120 during rotation, thereby facilitating the adjustment of the rotation angle of the driving disc 120. Figure 1 Figure 1

[0073] In the example shown in the figure, the sub-grooves of the inner region and the outer region of the fifth sector V are communicated to define a tank inlet groove, which is communicated with the tank inlet of the resin tank through a tank inlet channel. The sub-grooves of the inner region of the fourth sector IV define a water supplement groove, which is communicated with the salt tank through a water supplement channel. The sub-grooves of the inner region and the outer region of the third sector III are communicated to define a bypass water distribution groove 113. The valve seat 119 is provided with a water outlet pipe, and the bypass water distribution groove 113 is communicated with the water outlet pipe. Figure 5 In this way, when water needs to be softened, the driving disc 120 is rotated so that one of the water passing holes 121 is communicated with the tank inlet groove, and the other water passing hole 121 is communicated with the balance groove 118. Water flows from the water inlet pipe to the water inlet groove 112. Part of the water in the water inlet groove 112 flows to the valve cavity 111, and then flows to the tank inlet groove through the water passing hole 121 communicated with the tank inlet groove, and then flows to the tank inlet of the resin tank. Another part of the water in the water inlet groove 112 flows to the balance groove 118, and then flows into the valve cavity 111 through the water passing hole 121 communicated with the balance groove 118, and then flows into the tank inlet groove through the water passing hole 121 communicated with the tank inlet groove, and finally flows to the tank inlet of the resin tank. When the user needs to use water, for example, when flushing the toilet, the driving disc 120 is rotated so that the water passing hole 121 is communicated with the bypass water distribution groove 113 and the balance groove 118. Part of the water in the water inlet groove 112 flows to the bypass water distribution groove 113 through the valve cavity 111 and the water passing hole 121. Another part of the water in the water inlet groove 112 flows to the bypass water distribution groove 113 through the balance groove 118 and the water passing hole 121, and finally flows out through the water outlet pipe to provide water to the user.

[0074] ​​​

[0075] According to some embodiments of the present application, the other side of the moving disc 120 is provided with at least one water barrier rib 127, which can waterproof the water distribution grooves 113 to avoid water leakage between the water distribution grooves 113. Referring to Figure 4 As shown, the side of the moving disc 120 facing the valve seat 119 is provided with a plurality of water barrier ribs 127, which are in close contact with the surface of the valve seat 119 to avoid water leakage between the water distribution grooves 113. As shown Figure 4 As shown, the water barrier rib 127 defines a transition groove 128, which extends along the radial direction of the moving disc 120. One end of the transition groove 128 is circular and located at the center of the moving disc 120, and the other end of the transition groove 128 is fan-shaped. As shown Figure 5 As shown, the center of the valve seat 119 is provided with a central groove, which is in communication with the sub-groove of the inner region of the sixth sector Ⅵ to define a water passing groove 1191. During the rotation of the moving disc 120, one end of the transition groove 128 is in communication with the central groove. In this way, the rotation of the moving disc 120 rotates by a certain angle to make the water passing groove 1191 communicate with the water passing hole 121, and the transition groove 128 communicates with the water passing hole 121 through the water passing groove 1191. The other end of the transition groove 128 communicates with the corresponding water distribution groove 113, and the transition groove 128 and the water passing groove 1191 can deliver water to the corresponding water distribution groove 113 to reduce the number of water passing holes 121 and simplify the control process.

[0076] For example, in the example of Figure 5 In the example of

[0077] Referring to Figure 1 and Figure 2As shown, according to some embodiments of the present application, the control valve 100 further comprises a stationary disc 114 clamped between the bottom wall of the valve cavity 111 and the movable disc 120, and the stationary disc 114 is provided with at least one communication hole corresponding to the water distribution groove 113. The number of the communication holes is the same as that of the water distribution grooves 113, and each communication hole corresponds to each water distribution groove 113. The stationary disc 114 can separate the movable disc 120 from the valve seat 119 to avoid the friction between the valve seat 119 and the movable disc 120, thereby prolonging the service life of the valve body 110. In addition, the stationary disc 114 is replaceable, and the maintenance cost is low. In some embodiments, the control valve 100 further comprises a gasket 115 clamped between the stationary disc 114 and the bottom wall of the valve cavity 111, i.e. clamped between the stationary disc 114 and the valve seat 119. The gasket 115 is a deformable member, and when the movable disc 120 is assembled, the gasket 115 is deformed to seal the communication between the water distribution grooves 113 of the movable disc 120, thereby preventing water from flowing between the water distribution grooves 113. As shown in the figure, the valve cavity 111 is provided with a receiving groove 117, and the valve seat 119 is provided with at least one protruding rib on the end face, which surrounds the opening of the water distribution groove 113. The end face of the valve seat 119 and the protruding rib together define the receiving groove 117. The gasket 115 is adapted to be received in the receiving groove 117. Figure 6 As shown, the bottom wall of the valve cavity 111 is provided with a receiving groove 117, and the valve seat 119 is provided with at least one protruding rib on the end face, which surrounds the opening of the water distribution groove 113. The end face of the valve seat 119 and the protruding rib together define the receiving groove 117. The gasket 115 is adapted to be received in the receiving groove 117.
