[0145] The water softener 100 and the water softener according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0146] As shown in FIG13 , the water softener provided by the present application includes a water softener valve 100, which is used to control the flow of water within the water softener. For example, the water softener valve 100 can control the flow of raw water, softened water, sewage, etc., to achieve corresponding functions. The water softener also includes a resin tank 190 and a salt tank 187. The resin tank 190 contains resin, which is used to adsorb metal ions such as calcium and magnesium in the raw water to reduce the hardness of the water and produce soft water. The resin tank 190 is connected to the water softener valve 100. The resin tank 190 has a central port and a resin port. A central tube 192 is provided within the resin tank 190, and the resin port is filled with resin surrounding the central tube 192. The central port is connected to the central tube 192, and the resin port is connected to the interior of the resin tank 190. The resin port can transport water into the resin tank 190 for contact with the resin. The inlet pipe 114 of the softening valve 100 is connected to the central zone port, while the resin zone port of the softening valve 100 is connected to the outlet pipe 115. During the resin adsorption of calcium and magnesium ions to produce soft water, raw water is transported from the resin zone port into the resin tank 190 to come into contact with the resin. The resin displaces the calcium and magnesium ions in the raw water, producing soft water, which is then discharged through the central zone port and central tube 192. Due to the direction of water flow within the resin tank 190 during this process, for ease of description, the resin zone port will be referred to as "resin tank inlet," and the central zone port will be referred to as "resin tank outlet."

[0147] Salt water is stored in the salt tank 187 and is connected to the softening valve 100. The salt tank 187 is also connected to the resin tank 190 via the softening valve 100. The salt tank 187 is adapted to provide salt water to the resin tank 190 to clean the reduced resin, allowing it to continue adsorbing calcium and magnesium ions. The softening valve 100 is used to control the flow of water. For example, the softening valve 100 can control the flow of raw water into the resin tank 190 for filtration to reduce the water hardness and create soft water.

[0148] 1 and 2 , a soft water valve 100 according to an embodiment of the present application includes a valve body 110 and a valve core assembly 140 .

[0149] Specifically, as shown in Figure 3, valve body 110 defines a valve chamber 111, which is equipped with a water inlet pipe 112, a water outlet pipe 113, a tank inlet pipe 114, and a tank outlet pipe 115. Valve chamber 111 defines a valve seat 116. Water inlet pipe 112 is adapted to communicate with a water source to provide raw water; water outlet pipe 113 is used to output water for user use; tank inlet pipe 114 is adapted to communicate with the inlet of resin tank 190, and tank outlet pipe 115 is adapted to communicate with the outlet of resin tank 190.

[0150] The valve core assembly 140 is mounted on the valve seat 116 and positioned within the valve chamber 111. The valve core assembly 140 is rotatable relative to the valve seat 116 to switch between a service position, a salt absorption position, a bypass position, a backwash position, and a water replenishment position. Thus, the valve core assembly 140 and the valve seat 116 define a service waterway, a salt absorption waterway, a bypass waterway, a backwash waterway, and a water replenishment waterway. Thus, by rotating the valve core assembly 140 to the desired position, the corresponding waterway is switched into a connected state, thereby controlling the flow of water within the water softener and simplifying the control logic. Furthermore, controlling the waterway within the water softener through the water softener valve 100 improves the integration of the water softener's control structure. In some embodiments, the cross-section of the valve chamber 111 is circular, and the valve seat 116 is cylindrical. In the example shown in FIG. 3 , the valve seat 116 is cylindrical. The valve seat 116 is located at the center of the valve chamber 111. In this way, on the one hand, it is easy to manufacture, and on the other hand, it is prevented that the valve body 110 interferes with the rotation of the valve core assembly 140.

[0151] In the service position, at least the service waterway is connected, allowing the softening valve 100 to deliver raw water to the resin tank 190, where the resin can absorb calcium and magnesium ions in the raw water to produce soft water. In the salt absorption position, at least the salt absorption waterway is connected, allowing the softening valve 100 to deliver salt water from the salt tank 187 to the resin tank 190. The salt water displaces the calcium and magnesium ions adsorbed on the resin, reducing the resin and allowing it to continue adsorbing calcium and magnesium ions. In the bypass position, at least the bypass waterway is connected, allowing the softening valve 100 to deliver raw water directly to the user. It is understood that users have diverse water needs, and the water hardness requirements vary in different scenarios. For example, when flushing a toilet, the impact of water hardness can be ignored, and the user can use raw water. In this case, switching the valve core assembly 140 to the bypass position to provide raw water for flushing the toilet reduces the resin filtration process and thus reduces resin consumption.

[0152] In the backwash position, at least the backwash waterway is connected. The water softener 100 delivers water to the resin tank 190 to flush the resin, loosen it, remove broken resin, and increase the spacing between resin particles. Consequently, after switching to the service position, the resin is fully exposed to the raw water, adsorbing calcium and magnesium ions and improving filtration efficiency. In the water replenishment position, at least the water replenishment waterway is connected. The water softener 100 delivers water to the brine tank 187 to replenish the brine.

[0153] According to the soft water valve 100 of the embodiment of the present application, by rotating the valve core assembly 140 to switch between the service position, salt absorption position, bypass position, backwash position and water replenishment position, the valve core assembly 140 and the valve seat 116 define the service water path, salt absorption path, bypass water path, backwash water path and water replenishment water path to control the flow direction of water in the water softener, realize the corresponding function, simplify the control logic and reduce the operating cost.

[0154] As shown in FIG3 , according to some embodiments of the present application, the outer circumferential wall of valve seat 116 and the inner circumferential wall of valve cavity 111 define a first water inlet cavity 130. Valve seat 116 defines a tank inlet cavity 131 and a second water inlet cavity 132, which are separated from each other. Tank inlet cavity 131 communicates with tank inlet pipe 114, and water inlet pipe 112 communicates with both first and second water inlet cavities 130, 132. Tank inlet cavity 131 communicates with either the first or second water inlet cavity 130, 132 via valve core assembly 140. The first and second water inlet cavities 130, 132, valve core assembly 140, and tank inlet cavity 131 collectively define a service waterway. Raw water is delivered to the first and second water inlet cavities 130, 132 via water inlet pipe 112, flows through valve core assembly 140 to tank inlet cavity 131, and is then delivered to the inlet of resin tank 190 via tank inlet pipe 114.

[0155] A bypass chamber 133 is defined within valve seat 116. This bypass chamber 133 communicates with outlet pipe 113 and is separated from second water inlet chamber 132. Bypass chamber 133 communicates with either first water inlet chamber 130 or second water inlet chamber 132 via valve core assembly 140. Together, the first and second water inlet chambers 130, 132, valve core assembly 140, and bypass chamber 133 define a bypass waterway. Raw water is delivered to the first and second water inlet chambers 130, 132 via inlet pipe 112, flows through valve core assembly 140 into bypass chamber 133, and finally exits through outlet pipe 113 to be provided to the user. This allows raw water to be delivered to resin tank 190 for filtration and softening via the service waterway, or to be provided to the user via the bypass waterway, enhancing the water softener's water supply flexibility and meeting user needs.

[0156] According to some embodiments of the present application, the water outlet pipe 113 and the tank outlet pipe 115 are connected via a bypass check valve 137, allowing one-way flow from the tank outlet pipe 115 to the water outlet pipe 113. As shown in Figures 2 and 15, the soft water valve 100 further includes a bypass check valve 137. The water outlet pipe 113 is connected to the tank outlet pipe 115, and the soft water produced by the resin tank 190 flows through the tank outlet pipe 115 to the water outlet pipe 113, and is then delivered to the user end. In this way, the water flowing in the water outlet pipe 113 can be the soft water produced in the resin tank 190 or the raw water flowing out through the bypass chamber 133. The bypass check valve 137 can be located in the water outlet pipe 113 or in the tank outlet pipe 115. The bypass check valve 137 can be one-way, allowing water to flow from the tank outlet pipe 115 to the water outlet pipe 113 in one direction, preventing water in the water outlet pipe 113 from flowing back into the resin tank 190. The connection between the bypass chamber 133 and the outlet pipe 113 is located between the bypass check valve 137 and the outlet of the outlet pipe 113 to prevent raw water in the bypass chamber 133 from flowing into the outlet pipe 115. As shown in Figures 2 and 15, in some embodiments, the soft water valve 100 also includes a flow meter 188. The flow meter 188 is disposed within the outlet pipe 113, closer to the outlet of the outlet pipe 113 than the connection between the bypass chamber 133 and the outlet pipe 113. The flow meter 188 is used to detect the water flow output from the outlet pipe 113. As shown in Figure 15, the flow meter 188 is inserted into the outlet pipe 113 and fixedly connected to the outlet pipe 113 via an insert 189.

[0157] As shown in FIG3 , according to some embodiments of the present application, the water outlet pipe 113 and the tank outlet pipe 115 extend along the same straight line to reduce the flow resistance of water, facilitate the output of water, and reduce the water retained in the water outlet pipe 113 and the tank outlet pipe 115. The diameter of the water outlet pipe 113 and the diameter of the tank outlet pipe 115 can be the same to further reduce the flow resistance of water. As shown in FIG3 , the water outlet pipe 113 and the tank outlet pipe 115 extend along the length of the valve body 110, with the port of the water outlet pipe 113 located on one side of the valve body 110 and the port of the tank outlet pipe 115 located on the other side of the valve body 110. This can improve the utilization rate of the outer surface of the valve body 110, facilitate the connection between the soft water valve 100 and the external pipeline, and simplify the pipeline layout within the water softener. In some embodiments, the water outlet pipe 113 and the tank outlet pipe 115 can both be located at the bottom of the valve chamber 111, and the connection between the bypass chamber 133 and the water outlet pipe 113 can be located at the bottom of the bypass chamber 133. This can reduce the resistance of water flowing to the outlet of the water outlet pipe 113, which is conducive to the outflow of all water in the bypass chamber 133.

[0158] According to some embodiments of the present application, the water outlet pipe 113 and the tank outlet pipe 115 are formed from a single pipe, which defines a communication channel therein. A bypass check valve 137 is embedded in the communication channel. The outer peripheral wall of the bypass check valve 137 is sealedly connected to the inner peripheral wall of the communication channel. The bypass check valve 137 divides the communication channel into the water outlet pipe 113 and the tank outlet pipe 115. For example, a sealing layer may be provided between the outer peripheral wall of the bypass check valve 137 and the inner peripheral wall of the communication channel; alternatively, a bypass sealing ring 1371 may be provided between the outer peripheral wall of the bypass check valve 137 and the inner peripheral wall of the communication channel to seal the connection between the bypass check valve 137 and the communication channel. A mounting groove is provided on at least one of the outer circumferential wall of bypass check valve 137 and the inner circumferential wall of the communication channel. A bypass sealing ring 1371 is positioned within the mounting groove. The depth of the mounting groove is less than the maximum cross-sectional width of bypass sealing ring 1371. When inserted within the mounting groove, bypass sealing ring 1371 at least partially protrudes from the groove. A limiting groove is also provided on the inner circumferential wall of the communication channel. The limiting groove is annular and extends along the circumference of the communication channel. Bypass check valve 137 is positioned within the limiting groove to axially limit the bypass check valve 137.

[0159] As shown in Figure 1, a mounting tube 1891 is connected to the peripheral wall of the outlet pipe 113, facing away from the valve body 110. Mounting tube 1891 communicates with the outlet pipe 113. A flowmeter 188 is inserted axially into mounting tube 1891, with the detection end of flowmeter 188 located within the outlet pipe 113. An insert 189 has a forked end and is inserted radially into mounting tube 1891. The forked end engages flowmeter 188 to secure it. Inserting and removing insert 189 allows for quick and easy installation.

[0160] As shown in FIG3 , in some embodiments, the valve seat 116 is cylindrical, and the bypass cavity 133, the tank inlet cavity 131, and the second water inlet cavity 132 are evenly distributed along the circumference of the valve seat 116. This improves the utilization of the valve seat 116. The valve body 110 can be integrally formed. By evenly distributing the bypass cavity 133, the tank inlet cavity 131, and the second water inlet cavity 132 along the circumference of the valve seat 116, the probability of deformation of the valve seat 116 due to uneven force during the molding process can be reduced, thereby improving the yield rate.

[0161] As shown in FIG. 2 , according to some embodiments of the present application, the valve core assembly 140 includes a drive assembly 141, a rotating shaft 150, and a rotor 160. The rotor 160 is disposed on the valve seat 116 and cooperates with the valve seat 116 to define a service waterway, a brine absorption waterway, a bypass waterway, a backwash waterway, and a water supply waterway. The drive assembly 141 is connected to the valve body 110, the rotating shaft 150 is rotatably connected to the valve body 110, the rotating shaft 150 is in transmission connection with the drive assembly 141, and the rotor 160 is fixedly connected to the rotating shaft 150, which drives the rotor 160 to rotate. The rotor 160 is adapted to be attached to the top of the valve seat 116. The drive assembly 141 drives the rotating shaft 150 to rotate, which in turn drives the rotor 160 to rotate, causing the rotor 160 to engage with the valve seat 116, thereby defining a service waterway, a brine absorption waterway, a bypass waterway, a backwash waterway, or a water replenishment waterway. For example, rotating the rotor 160 causes it to engage with the tank inlet chamber 131. Thus, the first water inlet chamber 130, the second water inlet chamber 132, the rotor 160, and the tank inlet chamber 131 collectively define a service waterway.

[0162] As shown in FIG2 , according to some embodiments of the present application, the drive assembly 141 includes a drive motor 142 and a gear assembly 143. The drive motor 142 is fixedly connected to the valve body 110, and the drive motor 142 may be fixedly connected to the valve body 110 via screws. The gear assembly 143 is drivingly connected between the drive motor 142 and the rotating shaft 150. As shown in FIG15 , in some embodiments, the gear assembly 143 includes a large gear 1431 and a small gear 1432. The rotor 160 is fixedly connected to one end of the rotating shaft 150, the large gear 1431 is fixedly connected to the other end of the rotating shaft 150, and the small gear 1432 is connected to the output shaft of the drive motor 142. The large gear 1431 and the small gear 1432 mesh with each other. The drive motor 142 drives the small gear 1432 to rotate, which in turn drives the large gear 1431 to rotate the rotating shaft 150, which in turn drives the rotor 160 to rotate. The transmission ratio between the small gear 1432 and the large gear 1431 is greater than 1, that is, the number of teeth of the large gear 1431 is greater than that of the small gear 1432, so as to amplify the driving torque and provide sufficient power to drive the rotating shaft 150 and the moving plate 160 to rotate.

[0163] As shown in FIG2 , according to some embodiments of the present application, the valve body 110 includes a valve body portion 117 and a valve plug cover 118 . The valve cavity 111 is disposed within the valve body portion 117 , and one side of the valve cavity 111 is open. The rotating shaft 150 is disposed through the valve cavity 111 , with one end of the rotating shaft 150 located within the valve cavity 111 and the other end of the rotating shaft 150 located outside the valve cavity 111 . The gear assembly 143 and the drive motor 142 are both located outside the valve cavity 111 . The valve plug cover 118 is disposed on the open end of the valve cavity 111 to seal the valve cavity 111 . The rotating shaft 150 is disposed through the valve plug cover 118 , and the gear assembly 143 is located outside the valve cavity 111 . As shown in FIG3 , a receiving groove 1171 is provided on the valve body portion 117 , and the drive motor 142 is adapted to be received in the receiving groove 1171 . The valve plug cover 118 is suitable for covering the receiving groove 1171 , and the output shaft of the driving motor 142 passes through the valve plug cover 118 . One end of the driving motor 142 abuts against and is fixedly connected to the valve plug cover 118 .

[0164] As shown in FIG2 , according to some embodiments of the present application, the rotating shaft 150 includes a vertical shaft 151 and a connecting disc 152. One end of the vertical shaft 151 is connected to the drive assembly 141. Specifically, the vertical shaft 151 is inserted into the valve cavity 111, and one end of the vertical shaft 151 is fixedly connected to the large gear 1431. The connecting disc 152 is provided at the other end of the vertical shaft 151. The connecting disc 152 is stacked and fixedly connected to the movable plate 160. The connecting disc 152 is disc-shaped to match the movable plate 160. The diameter of the connecting disc 152 can be less than or equal to the diameter of the movable plate 160. In some embodiments, a pressure block is provided on the side facing the valve plug cover 118. The pressure block is located in the valve cavity 111 and abuts against the connecting disc 152 to limit the rotating shaft 150 in the axial direction.

[0165] As shown in Figures 2 and 8, according to some embodiments of the present application, a first locking portion 153 is provided on the connecting disk 152, and a second locking portion 167 that cooperates with the first locking portion 153 is provided on the movable plate 160. One of the first locking portion 153 and the second locking portion 167 is a groove body, and the other is a protrusion. The first locking portion and the second locking portion cooperate to circumferentially limit the movable plate 160, so that the rotating shaft 150 can drive the movable plate 160 to rotate.

[0166] Both the first and second clips can be multiple, with the multiple first clips spaced apart along the circumference of the connecting disk 152, and the multiple second clips spaced apart along the circumference of the movable plate 160. The multiple first clips include a first positioning portion, and the multiple second clips include a second positioning portion. The first positioning portion mates with the second positioning portion to circumferentially position the movable plate 160 and the connecting disk 152 relative to each other, preventing misalignment during assembly of the rotating shaft 150 and the movable plate 160. For example, as shown in FIG8 , there are four second clips, three of which are grooves, and one is a protrusion. There are also four first clips, three of which are protrusions, and one is a groove. The first clip, which is a groove, mates with the second clip, which is a protrusion, to circumferentially position the movable plate 160 and the connecting disk 152, uniquely defining their relative circumferential positions for ease of assembly.

[0167] As shown in FIG2 , according to some embodiments of the present application, the valve body 110 further includes a control plate 119 , which is fixed relative to the valve seat 116 and can be fixedly connected to the valve plug cover 118 . The control plate 119 is sleeved on the rotating shaft 150 and is located between the valve plug cover 118 and the gear assembly 143 . A Hall sensor 1191 is provided on the control plate 119 , and a magnetic member is provided on the gear assembly 143 . The Hall sensor 1191 is used to sense the position of the magnetic member. Thus, the drive motor 142 can be controlled based on the position of the magnetic member detected by the Hall sensor 1191 , thereby controlling the rotation angle of the movable plate 160 to rotate the movable plate 160 to the corresponding position.

[0168] As shown in FIG2 , in some embodiments, multiple Hall sensors 1191 may be provided, spaced apart along the circumference of the rotating shaft 150. The locations of the Hall sensors 1191 correspond to the service position, salt absorption position, bypass position, backwash position, and water replenishment position, respectively. When the magnetic member moves closest to one of the Hall sensors 1191, the valve core assembly 140 switches to the position corresponding to that Hall sensor 1191. For example, one of the Hall sensors 1191 may correspond to the service position. When the magnetic member moves closest to that Hall sensor 1191, the valve core assembly 140 switches to the service position. The orthographic projections of the motion trajectories of each Hall sensor 1191 and the magnetic member on the control board 119 may overlap, thereby improving the detection accuracy of the Hall sensors 1191. When the valve core assembly 140 switches to the service position, the magnetic member faces the corresponding Hall sensor 1191. As shown in Figure 2, the water softener valve 100 also includes a cover 101, which covers and is fixedly connected to the valve body 110, providing sealing and protection. A mounting space is defined between the cover 101 and the valve body 110. The open end of the valve seat 116 is located within the mounting space, and the drive assembly 141 and control panel 119 are housed within the mounting space.

[0169] As shown in FIG2 , according to some embodiments of the present application, the valve core assembly 140 further includes a stator 170 , which is attached to the valve seat 116 and sandwiched between the movable plate 160 and the valve seat 116 . The stator 170 is fixed relative to the valve seat 116 , while the movable plate 160 is rotatable relative to the stator 170 . The stator 170 can separate the movable plate 160 from the valve seat 116 , preventing wear on the valve seat 116 during rotation of the stator 170 and extending the service life of the valve body 110 . Furthermore, the stator 170 is easily replaceable, facilitating subsequent maintenance. As shown in FIG5 , the stator 170 is provided with a fixed bypass hole 171 corresponding to and communicating with the bypass chamber 133 . The movable plate 160 cooperates with the stator 170 and the valve seat 116 to define a service waterway, a brine absorption waterway, a bypass waterway, a backwash waterway, and a water supply waterway. Specifically, the first water inlet chamber 130, the second water inlet chamber 132, the dynamic bypass hole 162, the fixed bypass hole 171, and the bypass chamber 133 collectively define a bypass water path. The stator 170 is further provided with a fixed water inlet hole 173 and a fixed tank inlet hole 174. The fixed water inlet hole 173 communicates with the second water inlet chamber 132, and the fixed tank inlet hole 174 communicates with the tank inlet chamber 131.

[0170] 2 and 7 , in some embodiments, a sealing gasket 180 is provided between the stator 170 and the valve seat 116. The shape of the sealing gasket 180 is the same as that of the stator 170, or the shape of the sealing gasket 180 is the same as the cross-sectional shape of the valve seat 116. This seals the stator 170 and the valve seat 116 to prevent water seepage, and also increases friction to fix the stator 170 relative to the valve seat 116, preventing the stator 170 from sliding with the movable plate 160. The sealing gasket 180 may be a rubber member that can deform to a certain extent to fit tightly against the valve seat 116 and the stator 170 to prevent water seepage.

[0171] 3 and 6 , according to some embodiments of the present application, a first fixing portion 1111 is provided on the inner wall of the valve chamber 111, and a second fixing portion 172 is provided on the periphery of the stator 170. The second fixing portion 172 engages with the first fixing portion 1111 to circumferentially position the stator 170 and prevent the stator 170 from rotating relative to the valve seat 116. One of the second fixing portion 172 and the first fixing portion 1111 is a groove, and the other is a protrusion. In the examples of FIG. 3 and FIG. 6 , the first fixing portion 1111 is a protrusion, and the second fixing portion 172 is a groove.

[0172] In some embodiments, there are multiple first fixing portions 1111 and multiple second fixing portions 172. The multiple first fixing portions 1111 are spaced apart along the circumferential direction of the valve cavity 111, and the second fixing portions 172 are spaced apart along the circumferential direction of the stator 170. Among the multiple first fixing portions 1111, the width of one first fixing portion 1111 is different from the widths of the other first fixing portions 1111. Among the multiple second fixing portions 172, the width of one second fixing portion 172 is different from the widths of the other second fixing portions 172. The first fixing portions 1111 and the second fixing portions 172 cooperate to position the relative positions of the stator 170 and the valve seat 116 in the circumferential direction, thereby preventing the stator 170 from being misaligned with the valve seat 116 during installation, which could result in sealing failure.

[0173] For example, as shown in FIG3 , there are three first fixing portions 1111 , all of which are protrusions. As shown in FIG6 , there are three second fixing portions 172 , all of which are protrusions. The circumferential width of one first fixing portion 1111 is greater than the circumferential widths of the other two first fixing portions 1111 , and the circumferential width of one second fixing portion 172 is greater than the circumferential widths of the other two second fixing portions 172 . The first fixing portion 1111 and the second fixing portion 172 cooperate to position the relative positions of the stator 170 and the valve seat 116 in the circumferential direction. This facilitates the installation of the stator 170, avoids misalignment of the stator 170 and resulting in poor sealing, and prevents water from leaking into the valve seat 116.

[0174] As shown in Figures 8 and 9 , according to some embodiments of the present application, the rotor 160 is provided with spaced-apart dynamic water inlet holes 161 and dynamic bypass holes 162. In the service position, the first and second water inlet chambers 130, 132 communicate with the tank inlet chamber 131 via the dynamic water inlet holes 161. The first and second water inlet chambers 130, 132, the dynamic water inlet holes 161, and the tank inlet chamber 131 define a service waterway. At this point, raw water is delivered to the first and second water inlet chambers 130, 132 via the water inlet pipe 112. The raw water in the first and second water inlet chambers 130, 132 flows into the tank inlet chamber 131 through the dynamic water inlet holes 161. The raw water in the tank inlet chamber 131 is then delivered to the inlet of the resin tank 190 via the tank inlet pipe 114. The raw water contacts the resin to reduce the concentration of calcium and magnesium ions, forming soft water. The soft water flows from the outlet of the resin tank 190 into the tank outlet pipe 115 , and flows unidirectionally to the water outlet pipe 113 through the tank outlet pipe 115 , and is finally transported to the user end through the pipeline.

[0175] In the bypass position, the first and second water inlet chambers 130, 132 communicate with the bypass chamber 133 via the dynamic bypass hole 162. These three chambers, along with the dynamic bypass hole 162 and the bypass chamber 133, define a bypass waterway. Raw water is delivered to the first and second water inlet chambers 130, 132 via the water inlet pipe 112. The raw water in the first and second water inlet chambers 130, 132 flows through the dynamic bypass hole 162 into the bypass chamber 133. The raw water in the bypass chamber 133 then flows out through the water outlet pipe 113 and is delivered to the user through a pipeline. As shown in Figure 3, the tank inlet chamber 131 and the bypass chamber 133 are spaced apart along the circumferential direction of the valve seat 116, and the dynamic water inlet hole 161 and the dynamic bypass hole 162 are spaced apart in the circumferential direction of the movable plate 160. By rotating the movable plate 160, the dynamic water inlet hole 161 can be switched to be connected or disconnected with the tank inlet chamber 131, and the dynamic bypass hole 162 can be switched to be connected or disconnected with the bypass chamber 133.

[0176] As shown in FIG8 , according to some embodiments of the present application, a water inlet channel 163 is provided on the surface of the movable plate 160 facing away from the valve seat 116. The water inlet channel 163 connects the movable water inlet hole 161 with the first water inlet chamber 130 to guide water in the first water inlet chamber 130 into the movable water inlet hole 161. As shown in FIG8 , the water inlet channel 163 can extend along an arc, that is, the water inlet channel 163 is arc-shaped, with one end of the arc-shaped water inlet channel 163 communicating with the movable water inlet hole 161 and the other end communicating with the movable bypass hole 162.

[0177] In some embodiments, a surface of the rotor 160 facing away from the valve seat 116 further includes a communication port 164, which is used to connect the water inlet channel 163 with the first water inlet chamber 130. Communication port 164 is located at the edge of the rotor 160 and extends radially along the rotor 160. Multiple communication ports 164 connect the water inlet channel 163 with the first water inlet chamber 130. These communication ports 164 are spaced apart along the circumference of the rotor 160, with some communicating with the dynamic water inlet hole 161 or the dynamic bypass hole 162. Water within the first water inlet chamber 130 can flow from multiple directions toward the dynamic water inlet hole 161 and the dynamic bypass hole 162. The multiple communication ports 164 can be evenly distributed along the circumference of the rotor 160 to uniformly direct water into the dynamic water inlet hole 161 and the dynamic bypass hole 162. Thus, when the connecting plate 152 and the movable plate 160 are connected, the water in the first water inlet chamber 130 can flow through the water inlet channel 163 and the connecting port 164 to the movable water inlet hole 161 and the movable bypass hole 162, and then flow into the tank inlet chamber 131 and the bypass chamber 133. When the water flows in the water inlet channel 163 and the connecting port 164, the water exerts pressure on the movable plate 160, causing the movable plate 160 to fit tightly against the valve seat 116, which helps to simplify the fixing structure of the movable plate 160.

[0178] As shown in Figures 10-13, Figure 10 is a schematic diagram of the structure of the water softener 100 when the valve core assembly 140 is in the service position. Figure 11 is a schematic diagram of the relative positions of the movable plate 160 and the stator 170 when the valve core assembly 140 is in the service position. Figure 12 is a schematic diagram of the relative positions of the movable plate 160 and the stator 170 when the valve core assembly 140 is in the service position from another perspective. Figure 13 is a cross-sectional view of the water softener when the valve core assembly 140 is in the service position, with arrows in the figure indicating the direction of water flow.

[0179] As shown in Figures 10 and 11, when the valve core assembly 140 is in the service position, the first water inlet chamber 130, the second water inlet chamber 132, the connecting port 164, the water inlet passage 163, the dynamic water inlet hole 161, the fixed tank inlet hole 174, and the tank inlet chamber 131 collectively define a service water path. The dynamic water inlet hole 161 communicates with the tank inlet chamber 131 via the fixed tank inlet hole 174. The dynamic water inlet hole 161 communicates with the first water inlet chamber 130 via the water inlet passage 163 and the connecting port 164. The dynamic bypass hole 162 communicates with the second water inlet chamber 132 via the fixed water inlet hole 173. Thus, raw water is transported to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 can flow into the water inlet channel 163 through the connecting port 164 (the flow direction indicated by arrow 1 in Figures 10 and 11), and then flow into the dynamic water inlet hole 161 (the flow direction indicated by arrow 2 in Figures 10 and 11). The raw water in the second water inlet chamber 132 can flow into the water inlet channel 163 through the fixed water inlet hole 173 and the dynamic bypass hole 162, and then flow into the dynamic water inlet hole 161. After the raw water flows into the dynamic water inlet hole 161, it flows into the tank inlet chamber 131 through the fixed tank inlet hole 174. The raw water in the tank inlet chamber 131 is then transported to the inlet of the resin tank 190 through the tank inlet pipe 114.

[0180] As shown in Figure 13, the inlet and outlet of the resin tank 190 are both located at one end of the resin tank 190. A central tube 192 is provided within the resin tank 190. One end of the central tube 192 is connected to the outlet of the resin tank 190, and the other end of the central tube 192 is connected to the resin tank 190. The resin is housed within the resin tank 190 and located outside the central tube 192. Raw water enters the resin tank 190 from the inlet (in the direction of flow indicated by arrow 2 in Figure 13) and comes into contact with the resin. The resin absorbs the calcium and magnesium ions in the raw water, forming soft water. The soft water reaches the other end of the resin tank 190, flows from the central tube 192 to the outlet of the resin tank 190, and flows through the outlet pipe 115 and the bypass check valve 137 to the water outlet pipe 113. The soft water output by the water outlet pipe 113 is transported to the user end through a pipeline.

[0181] As shown in Figures 14 and 15, Figure 14 is a cross-sectional view of the water softener with the valve core assembly 140 in the bypass position. The arrows in the figures indicate the direction of water flow. In the bypass position, the first water inlet chamber 130, the second water inlet chamber 132, the connecting port 164, the water inlet passage 163, the dynamic bypass hole 162, the fixed bypass hole 171, and the bypass chamber 133 collectively define a bypass waterway. The dynamic bypass hole 162 communicates with the bypass chamber 133 via the fixed bypass hole 171. The dynamic bypass hole 162 communicates with the first water inlet chamber 130 via the water inlet passage 163 and the connecting port 164. The dynamic water inlet hole 161 communicates with the second water inlet chamber 132 via the fixed water inlet hole 173. Raw water is delivered to the first and second water inlet chambers 130 and 132 through the water inlet pipe 112 (in the direction of flow indicated by arrow 1 in FIG14 ). The raw water in the first water inlet chamber 130 flows into the dynamic bypass hole 162 through the connecting port 164 and the water inlet channel 163. The raw water in the second water inlet chamber 132 flows into the dynamic bypass hole 162 through the fixed water inlet hole 173, the dynamic water inlet hole 161, and the water inlet channel 163. The raw water flowing into the dynamic bypass hole 162 flows into the bypass chamber 133 through the fixed bypass hole 171. The raw water in the bypass chamber 133 flows out of the water outlet pipe 113 (in the direction of flow indicated by arrow 2 in FIG14 ) and is delivered to the user end through a pipeline. As shown in FIG14 , during this process, the raw water does not pass through the resin tank 190. This allows for flexible water supply according to user needs during use and reduces resin consumption.

[0182] As shown in FIG3 , according to some embodiments of the present application, the valve seat 116 is provided with a salt absorption chamber 134 and a salt absorption communication chamber 135, which are separated from each other. The salt absorption chamber 134 is adapted to communicate with the salt tank 187. As shown in FIG9 , the rotor 160 is provided with a dynamic salt absorption water diversion hole 165, which can be a blind hole and is located on the surface of the rotor 160 facing the valve seat 116. The salt absorption communication chamber 135 is adapted to communicate with the dynamic salt absorption water diversion hole 165. The dynamic water inlet hole 161 and the dynamic bypass hole 162 both penetrate the rotor 160 along the thickness direction of the rotor 160, and the dynamic salt absorption water diversion hole 165 is separated from the dynamic water inlet hole 161. In the salt absorption position, the dynamic water inlet hole 161 is connected to the dynamic salt absorption water diversion hole 165 through the salt absorption connecting chamber 135. The dynamic salt absorption water diversion hole 165 is connected to the salt absorption chamber 134 and the bypass chamber 133 respectively. The dynamic water inlet hole 161, the salt absorption connecting chamber 135, the dynamic salt absorption water diversion hole 165 and the salt absorption chamber 134 define a salt absorption path, and the dynamic water inlet hole 161, the salt absorption connecting chamber 135, the dynamic salt absorption water diversion hole 165 and the bypass chamber 133 define a bypass water path. In this way, in the salt absorption position, raw water can be provided to users through the bypass water path.

[0183] As shown in Figures 3 and 9, the salt absorption communication cavity 135 extends radially along the valve seat 116, with one end of the salt absorption communication cavity 135 located at the center of the valve seat 116. The dynamic salt absorption water diversion hole 165 extends radially along the rotor 160, with one end of the dynamic salt absorption water diversion hole 165 located at the center of the rotor 160. Thus, during the rotation of the rotor 160, one end of the salt absorption communication cavity 135 remains in communication with one end of the dynamic salt absorption water diversion hole 165. The salt absorption communication cavity 135 and the dynamic salt absorption water diversion hole 165 can function to connect the through hole in the rotor 160 with the chamber in the valve seat 116.

[0184] As shown in FIG3 , according to some embodiments of the present application, the cross-sectional profile of the salt absorption connecting chamber 135 includes a circular segment 1351 and a sector segment 1352, which are interconnected end-to-end to form a closed curve. The salt absorption connecting chamber 135 extends radially relative to the valve seat 116, with the circular segment 1351 located in the middle of the valve seat 116 and the sector segment 1352 located radially outward of the circular segment 1351. In the circumferential direction of the valve seat 116, the sector segment 1352 is located between the tank inlet chamber 131 and the second water inlet chamber 132. As shown in FIG9 , the cross-sectional profile of the dynamic salt absorption water diversion hole 165 is circular at one end and sector-shaped at the other. The dynamic salt absorption water diversion hole 165 extends radially relative to the rotor 160, with the circular end located in the middle of the rotor 160 to maintain communication with the circular segment 1351 of the salt absorption connecting chamber 135, and the sector-shaped end located radially outward of the circular end. The other fan-shaped end of the dynamic salt absorption and water distribution hole 165 is communicated with the salt absorption chamber 134 or the bypass chamber 133 by rotating the moving piece 160 .

[0185] Referring to Figures 16 to 20 , the valve core assembly 140 is in the salt absorption position. Figure 16 is a schematic structural diagram of the water softener 100, with arrows indicating the direction of water flow. Figure 17 is a schematic internal structural diagram of the valve chamber 111, not showing the rotor 160 and stator 170. Arrows indicate the direction of water flow. Figure 18 is a schematic diagram of the relative positions of the rotor 160 and stator 170. Figure 19 is a schematic diagram of the relative positions of the rotor 160 and stator 170 from another perspective. Arrows indicate the direction of water flow. Figure 20 is a cross-sectional view of the water softener, with arrows indicating the direction of water flow.

[0186] At the salt absorption position, the dynamic water inlet hole 161 communicates with the salt absorption communication chamber 135 through the fixed salt absorption communication hole 176 on the stator 170. The salt absorption communication chamber 135 communicates with the dynamic salt absorption water diversion hole 165 through the fixed salt absorption communication hole 176. The dynamic salt absorption water diversion hole 165 communicates with the bypass chamber 133 through the fixed bypass hole 171. The dynamic salt absorption water diversion hole 165 communicates with the salt absorption chamber 134 through the fixed salt absorption hole 175. The dynamic bypass hole 162 communicates with the second water inlet chamber 132 through the dynamic and fixed water inlet hole 173.

[0187] Raw water is introduced into the first and second water inlet chambers 130 and 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 flows through the connecting port 164 and the water inlet channel 163 to the dynamic water inlet hole 161. The raw water in the second water inlet chamber 132 flows through the fixed water inlet hole 173, the dynamic bypass hole 162, and the water inlet channel 163 to the dynamic water inlet hole 161. The raw water in the dynamic water inlet hole 161 flows into the salt absorption connecting chamber 135 through the fixed salt absorption connecting hole 176 (the flow direction is indicated by arrow 1 in Figures 18 and 19). The raw water in the salt absorption connecting chamber 135 flows into the dynamic salt absorption water diversion hole 165. In the dynamic salt absorption water distribution hole 165, a part of the raw water flows into the salt absorption chamber 134 through the fixed salt absorption hole 175 (the flow direction shown by arrow 2 in Figure 19); the other part of the raw water flows into the bypass chamber 133 through the fixed bypass hole 171 (the flow direction shown by arrow 3 in Figure 19), and the raw water in the bypass chamber 133 is output through the water outlet pipe 113 to be provided to the user.

[0188] According to some embodiments of the present application, the salt absorption chamber 134 can be selectively connected to the salt tank 187. When in the salt absorption position: the salt absorption chamber 134 is connected to the salt tank 187, the soft water valve 100 is in the salt absorption mode, and the salt water in the salt tank 187 and the raw water in the salt absorption chamber 134 are transported to the resin tank 190 to clean and restore the resin to restore its adsorption capacity; the salt absorption chamber 134 is disconnected from the salt tank 187, and the soft water valve 100 is in the slow wash mode. At this time, the salt tank 187 stops providing salt water, and the raw water in the salt absorption chamber 134 is transported to the resin tank 190 to flush the resin tank 190 to flush the salt in the resin. As shown in Figures 20 and 21, a salt valve 1871 can be provided in the salt tank 187 to control the connection between the salt tank 187 and the jet tube 181. In Figure 20, the soft water valve 100 is in the salt absorption mode, the salt valve 1871 is in the connected state, and the salt water is transported to the jet tube 181 through the salt valve 1871; in Figure 21, the soft water valve 100 is in the slow wash mode, the salt valve 1871 is in the closed state, and the salt tank 187 does not provide salt water.

[0189] As shown in FIG4 , in some embodiments, the soft water valve 100 further includes a jet tube 181 having an ejector 183 disposed therein. The jet tube 181 is connected to the valve body 110 and is in communication with the salt absorption chamber 134. The jet tube 181 is in communication with both the salt tank 187 and the resin tank 190. When the salt absorption chamber 134 is in communication with the salt tank 187, the ejector 183 can mix the water in the salt absorption chamber 134 with the salt water in the salt tank 187 and transport the mixture to the resin tank 190. When the salt absorption chamber 134 is disconnected from the salt tank 187, the jet tube 181 can transport the water in the salt absorption chamber 134 to the resin tank 190 to flush the resin.

[0190] As shown in FIG. 20 , according to some embodiments of the present application, the soft water valve 100 further includes a wastewater discharge line F, which is selectively connected to the tank inlet pipe 114. The tank inlet pipe 114 is connected to the inlet of the resin tank 190, thereby connecting the wastewater discharge line F to the resin tank 190 via the tank inlet pipe 114. In some embodiments, the wastewater discharge line F can also be directly connected to the resin tank 190. In the salt absorption position, the wastewater discharge line F is connected to the tank inlet pipe 114. Wastewater generated by cleaning the resin in the salt absorption mode and slow wash mode can be discharged through the wastewater discharge line F. In some embodiments, the soft water valve 100 further includes a pressure rod 191, which is used to control the connection between the wastewater discharge line F and the tank inlet pipe 114. As shown in FIG. 20 , the pressure rod 191 is located at the connection between the wastewater discharge line F and the tank inlet pipe 114, and a push block 1433 is provided on one side of the large gear 1431. When the valve core assembly 140 is located at the salt absorption position, the push block 1433 pushes the pressure rod 191 to move, so that the sewage discharge path F is connected to the tank inlet pipe 114.

[0191] As shown in Figure 20, the jet tube 181 is connected to the central tube 192 of the resin tank 190. When the soft water valve 100 is in salt absorption mode, the pressure rod 191 is in the open position, and the sewage discharge line F is connected to the tank inlet pipe 114. A portion of the raw water entering the soft water valve 100 is transported to the jet tube 181 through the salt absorption line (the flow direction indicated by arrow 2 in Figure 20). The jet tube 181 mixes the salt water with the raw water and transports it to the outlet of the resin tank 190. The mixed salt water flows through the central tube 192 to the other end of the resin tank 190 and comes into contact with the resin, thereby displacing the calcium and magnesium ions adsorbed on the resin and restoring the resin's adsorption capacity. After cleaning the resin, the mixed salt water flows out of the inlet of the resin tank 190 and is discharged through the sewage discharge line F. The remaining raw water entering the soft water valve 100 is transported to the outlet pipe 113 through the bypass waterway (the flow direction indicated by arrow 3 in Figure 20) for supply to the user. As shown in Figure 21, in slow-wash mode, the raw water flows in the same direction as in the brine absorption mode described above, except that brine is not supplied by brine tank 187. This is not further described here. In the brine absorption position, the softening valve 100 supplies water via the brine absorption line and the bypass water line. This allows water to be supplied to the user simultaneously with the resin cleaning and reduction process, ensuring uninterrupted water supply and preventing any disruption to user water usage.

[0192] As shown in Figures 3 and 9 , according to some embodiments of the present application, the rotor 160 is provided with a dynamic backwash hole 166 extending through its thickness, the seat body is provided with a backwash chamber 136, and the valve body 110 is provided with a backwash pipe 182, which is connected to the backwash chamber 136 and further connected to the center pipe 192 of the resin tank 190. In the example of Figure 3 , the backwash chamber 136 and the salt absorption chamber 134 are spaced apart in the radial direction of the valve seat 116. In the example of Figure 9 , the dynamic water inlet hole 161, the dynamic backwash hole 166, and the dynamic bypass hole 162 are spaced apart in the circumferential direction of the rotor 160.

[0193] In the backwash position, backwash chamber 136 communicates with dynamic bypass hole 162 to define a backwash water path; dynamic backwash hole 166 communicates with bypass chamber 133 to define a bypass water path. In the backwash position, a portion of the raw water entering the soft water valve 100 is transported through the backwash water path and backwash pipe 182 to the resin tank 190 to rinse the resin, remove broken resin, and increase the spacing between the resin particles. This ensures that when switched to the service position, the resin particles are fully exposed to the raw water, enhancing the adsorption of calcium and magnesium ions in the raw water. The remaining portion of the raw water entering the soft water valve 100 is discharged through the bypass water path and outlet pipe 113 to be provided to the user, ensuring uninterrupted water supply. When the valve core assembly 140 is in the backwash position, the wastewater discharge path F communicates with the resin tank 190 to discharge wastewater generated during the backwash process.

[0194] As shown in Figures 22 to 25, the valve core assembly 140 is in the backwash position, and the arrows in the figures indicate the direction of water flow. Figure 22 is a schematic diagram of the structure of the water softener 100; Figure 23 is a schematic diagram of the relative positions of the rotor 160 and stator 170; Figure 24 is a schematic diagram of the relative positions of the rotor 160 and stator 170 from another perspective; and Figure 25 is a cross-sectional view of the water softener.

[0195] In the backwash position, the valve core assembly 140 and the valve seat 116 define a backwash waterway and a bypass waterway. The dynamic bypass hole 162 communicates with the backwash chamber 136 via the fixed backwash hole 177. The dynamic backwash hole 166 communicates with the bypass chamber 133 via the fixed bypass hole 171. The dynamic water inlet hole 161 communicates with the second water inlet chamber 132 via the fixed water inlet hole 173. Raw water is transported through the water inlet pipe 112 to the first water inlet chamber 130 and the second water inlet chamber 132 (the flow direction is indicated by arrow 1 in Figure 25). The raw water in the first water inlet chamber 130 flows into the dynamic bypass hole 162 and the dynamic backwash hole 166 through the connecting port 164 and the water inlet channel 163. The raw water in the second water inlet chamber 132 flows into the dynamic bypass hole 162 and the dynamic backwash hole 166 through the fixed water inlet hole 173, the dynamic water inlet hole 161, and the water inlet channel 163.

[0196] The raw water flowing to the dynamic bypass hole 162 flows into the backwash chamber 136 through the fixed backwash hole 177 (the flow direction shown by arrow 2 in Figures 23 to 25), and then flows into the central tube 192 of the resin tank 190 through the backwash pipe 182. The raw water is transported to the other end of the resin tank 190 through the central tube 192 to flush the resin. At the backwash position, the sewage discharge path F is connected to the tank inlet pipe 114 of the resin tank 190. The sewage generated after the raw water flushes the resin flows out through the inlet of the resin tank 190 and is discharged from the sewage discharge path F. In some embodiments, a plurality of push blocks 1433 are provided on the large gear 1431. When the valve core assembly 140 moves to the backwash position, one of the push blocks 1433 pushes the pressure rod 191, so that the sewage discharge path F is connected to the tank inlet pipe 114. Raw water flowing into the dynamic backwash hole 166 flows through the fixed bypass hole 171 into the bypass chamber 133 (as indicated by arrow 3 in Figures 23 to 25 ), and is then discharged from the water outlet pipe 113 to the user. This ensures uninterrupted water supply to the water softener during the backwash process. As shown in Figures 13 and 25 , the water flow within the resin tank 190 is opposite in the service and backwash positions.

[0197] As shown in FIG3 , according to some embodiments of the present application, backwash pipe 182 extends in the same direction as tank inlet pipe 114 and tank outlet pipe 115. This facilitates connection to resin tank 190, facilitates piping routing, and simplifies the structure of the water softener. In the example of FIG3 , backwash pipe 182, tank inlet pipe 114, and tank outlet pipe 115 are located on the same side of valve body 110, with backwash pipe 182 located between tank inlet pipe 114 and tank outlet pipe 115. Tank inlet chamber 131 and backwash chamber 136 are both located on the side of valve seat 116 near tank inlet pipe 114 and jet pipe 181, simplifying the internal structure of valve seat 116.

[0198] According to some embodiments of the present application, the valve seat 116 is provided with a water supply chamber separated from the salt absorption chamber 134. The soft water valve 100 also includes a water supply pipe connected to the valve body 110, and the water supply chamber is connected to the water supply pipe. A water supply check valve 138 is provided between the water supply pipe and the jet pipe 181. The water supply check valve 138 is unidirectional based on the pressure difference between the water supply pipe and the jet pipe 181 to control the connection and disconnection between the jet pipe 181 and the resin tank 190. For example, in the example of FIG20 , when the valve core assembly 140 is in the salt absorption position, raw water flows into the jet pipe 181 through the salt absorption path, and no water flows through the water supply pipe. At this time, the pressure in the jet pipe 181 is greater than that in the water supply pipe, and the jet pipe 181 is connected to the resin tank 190, allowing raw water to flow from the jet pipe 181 to the resin tank 190.

[0199] In the water replenishment position, the dynamic water inlet 161 is connected to the water replenishment chamber and the salt absorption chamber 134. The pressure difference between the water replenishment pipe and the jet pipe 181 is zero. The water replenishment check valve 138 blocks the connection between the jet pipe 181 and the resin tank 190, while the jet pipe 181 remains connected to the salt tank 187. The salt absorption chamber 134 replenishes water into the salt tank 187 through the jet pipe 181. The dynamic water inlet 161, the water replenishment chamber, the salt absorption chamber 134, and the jet pipe 181 define a water replenishment waterway. It is understood that the salt tank 187 typically contains salt, and it is necessary to maintain a "salt-invisible" state in the salt tank 187 to avoid a failure in the salt tank 187 to provide salt water during use, resulting in resin reduction failure. In the water replenishment position, water is replenished to the salt tank 187 through the water replenishment waterway to dissolve the salt in the salt tank 187 and replenish the salt water.

[0200] As shown in Figures 13 and 37 , according to some embodiments of the present application, an ejector 183 is provided on an ejector tube 181. The ejector 183 includes a water inlet 184, a water outlet 185, and an intermediate connecting end 186. The water inlet 184 communicates with the salt absorption chamber 134, and the intermediate connecting end 186 communicates with the salt tank 187 to replenish the salt tank 187. Alternatively, salt water in the salt tank 187 is discharged through the intermediate connecting end 186 to mix with raw water input from the water inlet 184, thereby providing mixed salt water to the resin tank 190. The water outlet 185 communicates with the resin tank 190 to provide salt water to the resin tank 190. In the salt absorption position, the water inlet 184 of the ejector tube 181 provides raw water, the intermediate connecting end 186 provides salt water, and the water output from the water outlet 185 is a mixed salt water obtained by mixing the raw water and salt water. The mixed salt water is then transported to the resin tank 190 to clean the reducing resin. The water outlet 185 is connected to one side of the water replenishment check valve 138, and the backwash pipe 182 is connected to the other side of the water replenishment check valve 138. In the water replenishment position, the dynamic water inlet 161 is connected to both the backwash chamber 136 and the salt absorption chamber 134. The water pressure on both sides of the water replenishment check valve 138 is the same. The water replenishment check valve 138 is closed, and the direction from the jet pipe 181 to the resin tank 190 is blocked. Raw water is input through the water inlet 184 and output through the intermediate connecting port 186 to replenish the salt tank 187.

[0201] As shown in FIG3 , according to some embodiments of the present application, the jet tube 181 extends in the same direction as the tank inlet tube 114 and the tank outlet tube 115. This facilitates connection to the resin tank 190, facilitates piping routing, and simplifies the structure of the water softener. In the example of FIG3 , the jet tube 181, the tank inlet tube 114, and the tank outlet tube 115 are located on the same side of the valve body 110, with the jet tube 181 located between the tank inlet tube 114 and the tank outlet tube 115. The tank inlet chamber 131 and the salt absorption chamber 134 are both located on the side of the valve seat 116 close to the tank inlet tube 114 and the jet tube 181.

[0202] As shown in Figures 34 and 35 , according to some embodiments of the present application, the water replenishment check valve 138 includes a first base 1381, a second base 1383, and a check ball 1385. The first base 1381 defines a first channel 1382, which communicates with the backwash pipe 182. The second base 1383 and the first base 1381 define a movable space. The second base 1383 defines a second channel 1384, which communicates with the jet pipe 181. The first channel 1382 communicates with the backwash pipe 182, and both the first channel 1382 and the second channel 1384 communicate with the movable space. As shown in Figure 36 , in some embodiments, the first base 1381 is a frame structure, and the second base 1383 is cylindrical. The first base 1381 fits within the second base 1383 and is interlocked with the second base 1383. Check ball 1385 is movably disposed within the active space. The pressure differential between backwash pipe 182 and ejector pipe 181 causes check ball 1385 to block or open the connection between second channel 1384 and the active space. As shown in Figure 35 , when the pressure within backwash pipe 182 is greater than or equal to the pressure within ejector pipe 181, check ball 1385 blocks the top of second channel 1384, shutting off the connection between ejector pipe 181 and resin tank 190. Water within ejector pipe 181 is then transported to brine tank 187 via middle connecting end 186 of ejector 183. When the pressure within ejector pipe 181 is greater than the pressure within backwash pipe 182, such as in the brine absorption position, check ball 1385 moves toward first channel 1382, opening second channel 1384. Water output from outlet end 185 of ejector 183 flows through water replenishment check valve 138 to resin tank 190.

[0203] As shown in FIG. 34 , according to some embodiments of the present application, the water supply check valve 138 further includes an inner check ring 1386, which is positioned at the connection point between the second channel 1384 and the movable space. The check ball 1385 is adapted to be sealed with the inner check ring 1386. The inner check ring 1386 is embedded in the second base 1383 and may be a rubber seal. In some embodiments, the water supply check valve 138 further includes an outer check ring 1387, which is fitted over the outer circumferential wall of the first base 1381, or alternatively, the outer check ring 1387 may be fitted over the outer circumferential wall of the second base 1383. In some embodiments, there may be multiple outer check rings 1387, with at least one of the multiple outer check rings 1387 fitting over the outer circumferential wall of the first base 1381 and at least one of the multiple outer check rings 1387 fitting over the outer circumferential wall of the second base 1383, to improve sealing performance.

[0204] In some embodiments, the water supply chamber and the backwash chamber 136 are the same chamber, and the water supply pipe and the backwash pipe 182 are the same pipe. That is, the backwash chamber 136 is the water supply chamber, and the backwash pipe 182 is the water supply pipe. For ease of understanding, the structure and operation of the soft water valve 100 in the water supply position are described below using the example of the water supply chamber and the backwash chamber 136 being the same chamber and the water supply pipe and the backwash pipe 182 being the same pipe.

[0205] As shown in Figures 26-29, the valve core assembly 140 is now in the water replenishment position, with the arrows in the figures indicating the direction of water flow. Figure 26 is a schematic structural diagram of the soft water valve 100; Figure 27 is a schematic diagram of the relative positions of the movable plate 160 and the fixed plate 170; and Figure 28 is a schematic diagram of the relative positions of the movable plate 160 and the fixed plate 170 from another perspective. In the water replenishment position, the dynamic water inlet hole 161 communicates with the salt absorption chamber 134 via the fixed salt absorption hole 175. The dynamic water inlet hole 161 communicates with the backwash chamber 136 via the fixed backwash hole 177, and the dynamic backwash hole 166 communicates with the tank inlet chamber 131 via the fixed tank inlet hole 174. The first water inlet chamber 130, the dynamic water inlet hole 161, the water replenishment chamber, the salt absorption chamber 134, and the jet tube 181 define a water replenishment waterway. The first water inlet chamber 130, the dynamic backwash hole 166, and the tank inlet chamber 131 collectively define a service waterway.

[0206] Raw water is delivered to the first and second water inlet chambers 130 and 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 flows through the connecting port 164 and the water inlet channel 163 to the dynamic water inlet hole 161 and the dynamic backwash hole 166. A portion of the raw water in the dynamic water inlet hole 161 flows into the backwash chamber 136 through the fixed backwash hole 177 and then into the backwash pipe 182. Another portion of the raw water in the dynamic water inlet hole 161 flows into the brine chamber 134 through the fixed brine inlet hole 175 and then into the jet pipe 181. This balances the pressure exerted by the water in the backwash pipe 182 on the water supply check valve 138 with the pressure exerted by the water in the jet pipe 181 on the water supply check valve 138. The water supply check valve 138 blocks the connection between the jet pipe 181 and the resin tank 190, while maintaining communication between the jet pipe 181 and the brine tank 187. Thus, the water in the salt absorption chamber 134 is transported to the salt tank 187 through the jet pipe 181 to replenish the salt water. The raw water in the dynamic backwash hole 166 flows into the tank chamber 131 through the fixed tank hole 174 and is then transported to the user end through the water outlet pipe 113.

[0207] As shown in Figure 3, in some embodiments, the valve seat 116 is further provided with multiple process chambers 1301. Fixed process holes 178 are provided on the stator 170, and the fixed process holes 178 are connected to the process chambers 1301. One process chamber 1301 is spaced apart from the salt absorption communication chamber 135 along the radial direction of the valve seat 116, and the process chamber 1301 is located radially outward of the salt absorption communication chamber 135. At the water replenishment position, the dynamic bypass hole 162 is connected to the process chamber 1301 through the fixed process hole 178. The provision of the process chambers 1301 prevents water from flowing between chambers within the valve seat 116.

[0208] As shown in FIG3 , according to some embodiments of the present application, the valve seat 116 is cylindrical, with the salt absorption chamber 134, tank inlet chamber 131, and second water inlet chamber 132 evenly distributed along the circumference of the valve seat 116. This improves the utilization of the valve seat 116. The valve body 110 can be integrally formed. By evenly distributing the bypass chamber 133, tank inlet chamber 131, and second water inlet chamber 132 along the circumference of the valve seat 116, the probability of deformation of the valve seat 116 due to uneven force during the molding process can be reduced, thereby improving the yield rate. The backwash chamber 136 and the salt absorption chamber 134 are spaced apart radially from each other along the valve seat 116, with the salt absorption chamber 134 located outside the backwash chamber 136 in the radial direction of the valve seat 116. As shown in FIG9 , the dynamic water inlet hole 161 is fan-shaped, so that when in the water replenishment position, the dynamic water inlet hole 161 is connected to both the salt absorption chamber 134 and the backwash chamber 136.

[0209] In some embodiments, the backwash pipe 182 extends in the same direction as the jet pipe 181, the tank inlet pipe 114, and the tank outlet pipe 115. This facilitates connection with the resin tank 190, facilitates pipe routing, and simplifies the structure of the water softener. As shown in Figure 3, the backwash pipe 182, the jet pipe 181, the tank inlet pipe 114 and the tank outlet pipe 115 are located on the same side of the valve body 110, and the backwash pipe 182 and the jet pipe 181 are located between the tank inlet pipe 114 and the tank outlet pipe 115. The tank inlet cavity 131, the backwash cavity 136 and the salt absorption cavity 134 are all located on the side of the valve seat 116 close to the tank inlet pipe 114 and the jet pipe 181, and the backwash cavity 136 and the salt absorption cavity 134 are adjacent to the tank inlet cavity 131, so as to facilitate the connection between the tank inlet pipe 114 and the tank inlet cavity 131, the backwash pipe 182 and the backwash cavity 136, and the jet pipe 181 and the salt absorption cavity 134, thereby simplifying the internal structure of the valve seat 116.

[0210] According to some embodiments of the present application, a mixed water zone is provided between the service position and the salt absorption position. When the valve core assembly 140 rotates to the mixed water zone, the valve core assembly 140 and the valve seat 116 jointly define a service waterway and a bypass waterway. As shown in FIG3 , in the circumferential direction of the valve seat 116 , the tank inlet chamber 131 , the salt absorption chamber 134 , and the bypass chamber 133 are arranged in sequence, with the salt absorption chamber 134 located between the tank inlet chamber 131 and the bypass chamber 133 . The service position and the salt absorption position are adjacent. As shown in FIG11 and FIG18 , the valve core assembly 140 can be switched from the service position to the salt absorption position by rotating a certain angle in the direction indicated by arrow A from the service position. As shown in Figures 31 and 32 , within the mixed water zone, dynamic water inlet hole 161 communicates with tank inlet chamber 131, and further communicates with dynamic salt absorption water diversion hole 165 via salt absorption connecting chamber 135. Dynamic salt absorption water diversion hole 165 communicates with bypass chamber 133. Dynamic water inlet hole 161 and tank inlet chamber 131 collectively define a service waterway, while dynamic water inlet hole 161, salt absorption connecting chamber 135, dynamic salt absorption water diversion hole 165, and bypass chamber 133 collectively define a bypass waterway. A portion of the raw water entering softening valve 100 is delivered to resin tank 190 via the service waterway to displace calcium and magnesium ions in the raw water, producing softened water. The softened water is then delivered to outlet pipe 113 via outlet pipe 115; another portion of the raw water is delivered to outlet pipe 113 via the bypass waterway. Thus, within the mixed water zone, the water output from outlet pipe 113 is a mixture of softened and raw water. In the mixed water zone, the valve core assembly 140 is adjusted to adjust the opening of the service water channel and the bypass water channel to adjust the amount of soft water and the amount of raw water in the outlet pipe 113, thereby achieving the purpose of adjusting the hardness of the water.

[0211] As shown in Figures 30 to 33, the valve core assembly 140 is located within the mixed water zone. Figure 30 is a schematic diagram of the structure of the water softener 100, with arrows indicating the direction of water flow. Figure 31 is a schematic diagram illustrating the relative positions of the rotor 160 and stator 170, with arrows indicating the direction of water flow. Figure 32 is a schematic diagram illustrating the relative positions of the rotor 160 and stator 170 from another perspective. Figure 33 is a cross-sectional view of the water softener.

[0212] In the mixed water zone, the dynamic water inlet hole 161 communicates with the tank inlet chamber 131 via the fixed tank inlet hole 174. Furthermore, the dynamic water inlet hole 161 communicates with the salt absorption connecting chamber 135 via the fixed salt absorption connecting hole 176. The salt absorption connecting chamber 135 communicates with the dynamic salt absorption water diversion hole 165, which in turn communicates with the bypass chamber 133 via the fixed bypass hole 171. The dynamic bypass hole 162 communicates with the second water inlet chamber 132 via the fixed water inlet hole 173. At this time, raw water is input into the first and second water inlet chambers 130, 132, through the water inlet pipe 112. Raw water in the first water inlet chamber 130 flows to the dynamic water inlet hole 161 through the connecting port 164 and the water inlet channel 163. Raw water in the second water inlet chamber 132 flows to the dynamic water inlet hole 161 through the fixed water inlet hole 173, the dynamic bypass hole 162, and the water inlet channel 163.

[0213] A portion of the raw water in dynamic water inlet 161 flows through fixed inlet hole 174 into inlet chamber 131 (as indicated by arrow 1 in Figures 31 and 32). The raw water in inlet chamber 131 is then transported via inlet pipe 114 to the inlet of resin tank 190 (as indicated by arrow 1 in Figure 33). The raw water then enters resin tank 190 and comes into contact with the resin, displacing calcium and magnesium ions, forming soft water. The soft water is then discharged through central pipe 192 and the outlet of resin tank 190, and transported via outlet pipe 115 to outlet pipe 113 (as indicated by arrow 1' in Figure 33).

[0214] Another portion of the raw water in the dynamic water inlet hole 161 flows into the dynamic salt absorption water distribution hole 165 through the fixed salt absorption connecting hole 176 and the salt absorption connecting chamber 135, and then flows into the bypass chamber 133 (as shown by the flow direction of arrow 2 in Figures 31 and 32). The raw water in the bypass chamber 133 flows into the outlet pipe 113 (as shown by the flow direction of arrow 2 in Figure 33). The water in the outlet pipe 113 is a mixture of soft water and raw water. As shown in Figure 32, the opening of the fixed salt absorption connecting hole 176 and the fixed inlet tank hole 174 can be adjusted by adjusting the rotation angle of the valve core assembly 140 to adjust the amount of raw water flowing into the inlet tank chamber 131 and the bypass chamber 133, thereby adjusting the ratio of soft water to raw water in the outlet pipe 113 to achieve the purpose of adjusting the hardness of the water.

[0215] As shown in Figure 6, the fixed salt intake holes 175 and the fixed bypass chamber 133 are distributed along the circumference of the stator 170. The angle between the fixed salt intake holes 175 and the fixed bypass chamber 133 is the mixing angle. In the example shown in Figure 6, the mixing angle is 35 degrees. In some embodiments, the mixing angle can also be 20 degrees, 30 degrees, or other angles. As shown in Figure 11, when the valve core assembly 140 rotates from the service position in the direction of arrow A to the salt intake position, when the rotation angle is less than the mixing angle, the dynamic salt intake water diversion holes 165 communicate with the bypass chamber 133, and the dynamic salt intake water diversion holes 165 do not communicate with the salt intake chamber 134. As shown in Figure 9, in some embodiments, the side of the rotor facing the valve seat 116 is provided with multiple blind holes 168. The blind holes 168 are used to collect water from the valve chamber 116. Sealing ribs are formed between the multiple blind holes 168 to seal the chambers on the valve seat 116 that are not suitable for water flow during operation, preventing water from flowing between the chambers on the valve seat 116.

[0216] As shown in Figure 5, according to some embodiments of the present application, the cross-section of the valve seat 116 is circular, and the circle is equally divided into six sector-shaped areas 120. The central angle corresponding to each sector-shaped area 120 is 60 degrees. Along the circumferential direction of the valve seat 116, there are the first area, the second area 122, the second area 122, the third area 123, the fourth area 124, the fifth area 125 and the sixth area 126, respectively. The tank inlet cavity 131 is located in the first area.

[0217] The valve seat 116 is provided with a bypass chamber 133 and a salt intake communication chamber 135, each separated from the salt intake chamber 134 and the second water inlet chamber 132. The bypass chamber 133 is located in the third section 123, and the tank inlet chamber 131 and the bypass chamber 133 are spaced 60 degrees apart. The tank inlet chamber 131 has a fan-shaped cross-section, or the bypass chamber 133 has a fan-shaped cross-section. In some embodiments, both the tank inlet chamber 131 and the bypass chamber 133 may also be fan-shaped. The second water inlet chamber 132 is located in the fifth section 125 and is fan-shaped. The second water inlet chamber 132 is spaced 60 degrees apart from the tank inlet chamber 131, the second water inlet chamber 132, and the bypass chamber 133. As shown in Figure 5, in some embodiments, the second water inlet chamber 132 is distributed in the fourth zone 124 and the fifth zone 125, wherein the portion located in the fifth zone 125 is fan-shaped, and the portion located in the fourth zone 124 is arc-shaped, and a process chamber 1301 is also provided in the fourth zone 124. In the radial direction of the valve seat 116, the process chamber 1301 is located on the inner side of the second water inlet chamber 132.

[0218] The backwash chamber 136 and the salt absorption chamber 134 are both located in the second zone 122. As shown in FIG5 , the salt absorption chamber 134 is located in the second zone 122, and the stator 170 is provided with a fixed salt absorption hole 175 correspondingly connected to the salt absorption chamber 134. At least a portion of the salt absorption connecting chamber 135 is located in the sixth zone 126, and the stator 170 is provided with a fixed salt absorption connecting hole 176 correspondingly connected to the salt absorption connecting chamber 135. In the example of FIG5 , the circular section 1351 of the salt absorption connecting chamber 135 is located at the center of the valve seat 116, and the fan-shaped section 1352 of the salt absorption connecting chamber 135 is located in the sixth zone 126. The backwash chamber 136 is located in the second zone 122, and the stator 170 is provided with a fixed backwash hole 177 correspondingly connected to the backwash chamber 136. The backwash chamber 136 is separated from the salt absorption chamber 134. In the example of FIG5 , the backwash chamber 136 and the salt absorption chamber 134 are distributed along the radial direction of the valve seat 116 , and the salt absorption chamber 134 is located inside the backwash chamber 136 in the radial direction of the valve seat 116 . The salt absorption chamber 134 is fan-shaped, and the backwash chamber 136 is arc-shaped.

[0219] By evenly dividing the valve seat 116 into six sector-shaped areas 120, and arranging the tank inlet chamber 131, the bypass chamber 133, the salt absorption chamber 134, the salt absorption connecting chamber 135, the backwash chamber 136 and the second water inlet chamber 132 according to the sector-shaped areas 120, the utilization rate of the valve seat 116 can be improved. In a limited space, the cross-sectional areas of the tank inlet chamber 131, the bypass chamber 133 and the second water inlet chamber 132 can be maximized, thereby increasing the water flow rate.
