DETAILED DESCRIPTION

[0285] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them.

[0290] Hard water can have a variety of impacts on daily life and household appliances. For example, it can reduce washing efficiency, accumulate in pipes, reducing water flow, impairing equipment performance and lifespan, and causing skin problems. Therefore, people often use water softeners to treat their tap water. Using water softeners can effectively remove minerals from hard water, improving water quality and enhancing the quality of life. Water softeners typically work by removing calcium and magnesium ions from water through an ion exchange process, thereby converting hard water into soft water.

[0291] Resin treatment is a common method. Resin is a polymer with a unique structure that carries a positive surface charge. When hard water passes through the resin particles, the calcium and magnesium ions in the resin attract the positive charges on the resin surface, replacing the sodium ions already on the resin. Over time, the resin particles gradually become saturated, requiring cleaning by aspirating salt water to regenerate the resin particles by replacing the adsorbed ions.

[0292] In the prior art, control valves are used to switch the water circuits to achieve the various functions of the water softener. Wastewater after cleaning the resin particles is discharged through a separate drainage channel. In other words, the switching of the water circuits and the opening of the drainage channel are controlled separately in the prior art. This increases the complexity of the control system, the number of parts required, and the manufacturing cost. Furthermore, the complex control system reduces the reliability of the entire device.

[0293] In the related art, in order to achieve the softening effect, the water softener is usually connected to a resin tank or resin barrel. Since the water softener needs to be cleaned and regenerated, the overall structure is often complicated, which makes the overall components unfavorable for layout, making the overall structure complicated and occupying a large space.

[0294] In view of the problems in the related art, referring to Figures 1-3, the present application provides a water softener, which includes a water softener valve 100, an adapter assembly 200, a water channel assembly 300 and a resin tank 400. The water softener 100 includes a valve body 110, a valve core assembly 140, a driving part 142 and a transmission mechanism 141. The valve core assembly 140 and the driving part 142 are both arranged in the valve body 110. The driving part 142 is connected to the valve core through the transmission mechanism 141, so that the valve core assembly 140 is controlled by the driving part 142. Waterway switching; the adapter assembly 200 is connected to the softening valve 100 and is located on one side of the softening valve 100. The adapter assembly 200 has a sewage discharge channel 2107. The adapter assembly 200 cooperates with the transmission mechanism 141, and the drive unit 142 is suitable for driving the transmission mechanism 141 to control the opening of the sewage discharge channel 2107. The waterway assembly 300 is connected to the adapter assembly 200 and is used to guide the flow of the waterway. The resin tank 400 is fixedly connected to the waterway assembly 300 and is used to soften the water flowing through it. When the water softener is in operation, the waterway flowing through the resin tank 400 has different flow directions depending on the function required. The waterway is specified to flow from the resin filling area at the top of the resin tank 400, then rises through the central pipe 410, and then is output as a forward circulation waterway. The waterway is specified to flow from the central pipe 410, then rises through the resin particle filling area, and then is output as a reverse circulation waterway. In a water softener, the reverse circulation waterway is typically output through sewage discharge channel 2107, which is normally closed and opened when sewage discharge is required. In this embodiment, the drive unit 142 cooperates with the transmission mechanism 141 to control the switching of the various waterways. Furthermore, while controlling the switching of the various waterways, the drive unit 142 also cooperates with the adapter assembly 200 to open sewage discharge channel 2107. This allows the opening of each waterway in the water softener and the realization of various functions of the water softener, simplifying the water softener's control system and improving its stability.

[0295] In view of the problems existing in the related art, as shown in Figures 1-3, the present application also provides a water softener, which includes a soft water valve 100, an adapter assembly 200, a water channel assembly 300 and a resin tank 400. The soft water valve 100 includes a valve body 110, a valve core assembly 140, a driving part 142 and a transmission mechanism 141. The valve core assembly 140 and the driving part 142 are both arranged in the valve body 110. The driving part 142 is connected to the valve core assembly 140 through the transmission mechanism 141, so that the valve core assembly 140 is in the driving state. The waterway switching is controlled by the driving part 142; the adapter assembly 200 is connected to the soft water and is located on one side of the soft water valve 100; the waterway assembly 300 is connected to the adapter assembly 200 and is used to guide the flow of the waterway; the resin tank 400 is fixedly connected to the waterway assembly 300 and is used to soften the water flowing therethrough; wherein, the waterway assembly 300 has a first side and a second side arranged relative to each other, the soft water valve 100 and the adapter assembly 200 are arranged on the first side, and the resin tank 400 is arranged on the second side. Generally, because a water softener needs to have multiple flow channels for waterway switching control, it requires a relatively complex waterway structure and requires more components for waterway control. A larger space is required to designate the waterway structure, which is not conducive to the layout of the various components. This results in a larger overall space occupied by the water softener, especially in the thickness direction A of the water softener. In this example, the softening valve 100 and the adapter assembly 200 are connected to one side of the water channel assembly 300, and the resin tank 400 is arranged on the other side of the water channel assembly 300, so that the water softener as a whole is designed to be stacked in the vertical direction B, which significantly reduces the space occupied by the water softener, especially reduces the thickness of the water softener, and facilitates transportation and installation.

[0296] As can be understood, the adapter assembly 200 connects the water softener 100 and the waterway assembly 300, positioning them on a first side of the waterway assembly 300 and connecting the resin tank 400 to a second side of the waterway assembly 300. This creates a stacked arrangement along the vertical direction B, with the thickness direction A being only the width of the waterway plate, significantly reducing the space occupied by the water softener in the thickness direction A, as shown in FIG1 . Furthermore, the connection arrangement of the adapter assembly 200 reduces the space occupied by each component (the water softener 100 and the waterway assembly 300), facilitating the layout of the water softener and making the overall structure more compact, thereby reducing the overall space occupied by the water softener.

[0297] According to one embodiment of the present application, a connection port for fluid input or output is provided on the first side of the waterway assembly 300. The adapter assembly 200 is connected to the waterway assembly 300 via the connection port. The connection port is offset from one end of the first side, so that an installation space is formed between the connection port and the other end of the first side. The installation space is suitable for installing the soft water valve 100 and the adapter assembly 200. When installing the soft water valve 100 and the adapter assembly 200, space is required. In this embodiment, the position of the connection port is adjusted so that the connection port is located on one side, thereby creating an escape space on the first side of the waterway assembly 300. This escape space is used to install the soft water valve 100 and the adapter assembly 200, making the overall structure compact and reducing space usage.

[0298] In a specific configuration, as shown in FIG5 , the transmission mechanism 141 is in transmission connection with the drive unit 142. The drive unit 142 is capable of driving the transmission mechanism 141 to rotate. The rotation of the transmission mechanism 141 drives the valve core assembly 140 to rotate. When the valve core assembly 140 rotates to different positions, it can switch between different water paths, thereby achieving different functions of the water softener. For example, the transmission mechanism 141 has corresponding mating components. When the transmission mechanism 141 rotates or moves to a set position, the mating components engage with corresponding components on the adapter assembly 200 to open the sewage flow path 2107. While different functions of the water softener are being realized, the transmission mechanism 141 can cooperate with the adapter assembly 200 to open the sewage flow path 2107, thereby achieving the realization of different functional positions of the water softener by a single drive unit 142.

[0299] It is understandable that in order to realize the control of the sewage water path 2107 in the related art, it is often necessary to set up a separate control component and a corresponding control module for control, so as to realize the opening of the sewage water path 2107. The number of control components is large and the entire control system is complex. In this example, the action of the valve core assembly 140 can be controlled by the transmission component first, thereby realizing the switching of each water path, and in the switching process of each water path, the transmission mechanism 141 can cooperate with the adapter assembly 200, and the opening of the sewage water path 2107 can be realized by cooperating with the adapter assembly 200. That is, the water path switching and the control of the sewage water path 2107 are realized by the cooperation of a driving part 142 and a transmission mechanism 141, which reduces the control components, simplifies the control system and control logic, and improves the stability of the control system.

[0300] In specific applications, raw water is introduced through the softening valve 100 and then enters the resin tank 400 through the adapter assembly 200. The resin tank 400 is filled with resin pellets and a central tube 410. After being processed by the resin pellets in the resin tank 400, the raw water passes through the adapter assembly 200 and is output from the softening valve 100. The flow direction of the water channel in the resin tank 400 is controlled by the adapter assembly 200. In other words, the flow direction of the water channel in the resin tank 400 is controlled by the transmission mechanism 141 in conjunction with the adapter assembly 200, thereby controlling the forward and reverse circulation water channels in the resin tank 400.

[0301] As shown in Figures 6 and 7, according to one embodiment of the present application, a water softener 100 includes a valve body 110 with a valve chamber 111 disposed therein. Furthermore, the valve body 110 includes a water inlet pipe 112, a water outlet pipe 113, a tank inlet pipe 114, and a tank outlet pipe 115, all of which are connected to the valve chamber 111. A valve seat 116 is disposed within the valve chamber 111. A valve core assembly 140 is disposed on the valve seat 116 and positioned within the valve chamber 111. The valve core assembly 140 switches relative to the valve seat 116 between a service position, a salt absorption position, a bypass position, a backwash position, and a water replenishment position, thereby defining a service waterway, a salt absorption position, a bypass position, a backwash position, and a water replenishment position. In this embodiment, the water softener operates in the service position, the salt absorption position, the bypass position, the backwash position, and the water replenishment position, each of which corresponds to a waterway. The control of each waterway enables the softener to achieve different functions.

[0302] In a specific configuration, the water softener valve 100 is used to control the flow of water (including raw water, softened water, sewage, etc.) within the water softener to achieve the corresponding function. As shown in Figure 29, the water softener also includes a salt tank 500. As described above, the resin tank 400 is filled with resin particles, which are used to absorb metal ions such as calcium and magnesium in the raw water to reduce the hardness of the raw water. The resin tank 400 is connected to the water softener valve 100. The salt tank 500 contains salt water and is connected to the water softener valve 100. The salt tank 500 is suitable for providing salt water to the resin tank 400 to clean the reduced resin, allowing the resin to continue to absorb calcium and magnesium ions. The water softener valve 100 is used to control the flow of water. For example, the water softener valve 100 can control the flow of raw water into the resin tank 400 for filtration to reduce the water hardness and form soft water.

[0303] As can be understood, as shown in Figures 4-12, the water inlet pipe 112 is adapted to connect to a water source to provide raw water; the water outlet pipe 113 is adapted to connect to a user end to provide water for consumption; the tank inlet pipe 114 is adapted to connect to the inlet of the resin tank 400, and the tank outlet pipe 115 is adapted to connect to the outlet of the resin tank 400. In this embodiment, the water softener switches to a connected state at corresponding positions to deliver water to the corresponding locations. Thus, by rotating the valve core assembly 140 to the desired position, the corresponding water channel switches to a connected state, thereby controlling the flow direction of water within the water softener and simplifying the control logic. Furthermore, controlling the water flow within the water softener through the water softener valve 100 improves the integration of the water softener's control structure. In some embodiments, the valve chamber 111 has a circular cross-section, and the valve seat 116 is cylindrical and located at the center of the valve chamber 111.

[0304] In the service position, as shown in Figures 19-22, at least the service waterway is in a connected state, and the soft water valve 100 can transport raw water to the resin tank 400, so that the resin particles can absorb the calcium and magnesium ions in the raw water to produce soft water. In the salt absorption position, as shown in Figures 25-29, at least the salt water absorption waterway is in a connected state, and the soft water valve 100 can transport the salt water in the salt tank 500 to the resin tank 400. The salt water is used to displace the calcium and magnesium ions adsorbed on the resin to reduce the resin so that the resin can continue to adsorb calcium and magnesium ions. In the bypass position, as shown in Figures 23 and 24, at least the bypass waterway is in a connected state, and the soft water valve 100 can transport raw water directly to the user end. It is understandable that users have many water needs, and the demand for water hardness is different in different scenarios.

[0305] For example, when flushing a toilet, the influence of water hardness can be ignored, and the user can use raw water for flushing. In this case, the valve core assembly 140 is switched to the bypass position to provide raw water for flushing the toilet, which can reduce the resin filtration process and thus reduce resin consumption. In the backwash position, as shown in Figures 31-34, at least the backwash water path is in a connected state. At this time, the soft water valve 100 delivers water to the resin tank 400 to flush the resin, remove broken resin, and increase the gaps between resin particles. After switching to the service position, the resin is fully contacted with the raw water to adsorb calcium and magnesium ions, improving the filtration effect. In the water replenishment position, at least the water replenishment water path is in a connected relationship. The soft water valve 100 is suitable for delivering water to the salt tank 500 to replenish the salt water.

[0306] It can be understood that in this embodiment, the valve core assembly 140 is driven to rotate by the driving part 142 to switch between the service position, the salt absorption position, the bypass position, the backwash position and the water replenishment position. The valve core assembly 140 and the valve seat 116 define corresponding water paths to control the flow direction of water in the water softener, simplifying the control logic and reducing operating costs.

[0307] As shown in Figures 6 and 7, according to some embodiments provided herein, the outer peripheral wall of the valve seat 116 and the inner peripheral wall of the valve cavity 111 define a first water inlet cavity 130. The valve seat 116 includes a tank inlet cavity 131 and a second water inlet cavity 132, which are separated from each other. The tank inlet cavity 131 is in communication with the tank inlet pipe 114, and the water inlet pipe 112 is in communication with both the first water inlet cavity 130 and the second water inlet cavity 132. A bypass cavity 133 is provided in the valve seat 116, which is in communication with the water outlet pipe 113 and is separated from the second water inlet cavity 132. The tank inlet cavity 131 is in communication with the first water inlet cavity 130 or the second water inlet cavity 132 via the valve core assembly 140. The first water inlet cavity 130, the second water inlet cavity 132, the valve core assembly 140, and the tank inlet cavity 131 collectively define a service waterway. The raw water is delivered to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112 , flows to the tank inlet chamber 131 through the valve core assembly 140 , and is delivered to the inlet of the resin tank 400 through the tank inlet pipe 114 .

[0308] The bypass chamber 133 communicates with either the first water inlet chamber 130 or the second water inlet chamber 132 via the valve core assembly 140. The first water inlet chamber 130, the second water inlet chamber 132, the valve core assembly 140, and the bypass chamber 133 collectively define a bypass waterway. Raw water is delivered to the first and second water inlet chambers 130, 132 via the water inlet pipe 112, flows through the valve core assembly 140 into the bypass chamber 133, and finally flows out through the water outlet pipe 113 to be provided to the user. This allows the water softener to deliver raw water to the resin tank 400 for filtration and softening via the service waterway, while also providing raw water to the user via the bypass waterway, enhancing its flexibility.

[0309] 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 5 and 23, the soft water valve 100 also 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 400 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 includes the soft water produced in the resin tank 400 and 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 400. 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 toward the outlet pipe 115. As shown in Figures 5 and 23, in some embodiments, the soft water valve 100 further includes a flow meter 183. The flow meter 183 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 183 is used to detect the flow rate of water output from the outlet pipe 113. As shown in Figure 23, the flow meter 183 is inserted into the outlet pipe 113 and is fixedly connected to the outlet pipe 113 via a plug-in connection.

[0310] As shown in Figures 14 and 22, according to some embodiments of the present application, the adapter assembly 200 has a sewage control assembly 250, which is arranged in the sewage water path 2107. The sewage control assembly 250 is used to control the on and off of the sewage water path 2107. The transmission mechanism 141 includes a driving gear 1432, a driven gear 1431 and a rotating shaft 150. The driving gear 1432 is arranged at the output end of the driving part 142; the driven gear 1431 is engaged with the driving gear 1432, and the driven gear 1431 has at least one driving block 1433. The driving block 1433 is used to cooperate with the sewage control assembly 250 to realize the opening of the sewage water path 2107, and the rotating shaft 150 is connected to the driven gear 1431; wherein, the rotating shaft 150 is connected to the valve core assembly 140 to drive the valve core assembly 140 to control the water path switching. The sewage control assembly 250 opens the sewage discharge path 2107 by interacting with the driver block 1433 on the driven gear 1431. Specifically, when sewage discharge path 2107 needs to be opened, the rotation of the driven gear 1431 causes the driver block 1433 to squeeze the sewage control assembly 250, thereby opening sewage discharge path 2107. For example, in the salt absorption position, the salt absorption path is connected, and the soft water valve 100 can transfer salt water from the salt tank 500 to the resin tank 400. The salt water displaces the calcium and magnesium ions adsorbed on the resin, reducing the resin so that it can continue to adsorb calcium and magnesium ions. The reduced wastewater enters the sewage discharge path 2107 through the adapter assembly 200. At this time, the driver block 1433 squeezes the sewage control assembly 250, opening sewage discharge path 2107 and enabling direct discharge of sewage. This enables a single driver 142 to control both water path switching and the opening of sewage discharge path 2107, simplifying the control logic.

[0311] In a specific configuration, as shown in FIG5 , the drive unit 142 is a drive motor, which is fixedly connected to the valve body 110 and can be fixedly connected to the valve body 110 via screws. The driven gear 1431 is larger than the drive gear 1432. The two gears are meshed, and the drive motor drives the drive gear 1432 to rotate. The drive gear 1432 drives the driven gear 1431 to rotate, and the driven gear 1431 drives the rotating shaft 150 to rotate, which in turn drives the movable plate 160 within the valve core assembly 140 to rotate. The transmission ratio between the drive gear 1432 and the transmission gear is greater than 1, that is, the number of teeth on the drive gear 1432 is greater than that on the transmission gear, thereby amplifying the driving torque and providing sufficient power to drive the rotating shaft 150 and the movable plate 160 to rotate.

[0312] As shown in Figures 5, 11, and 12, according to some embodiments of the present application, the valve core assembly 140 includes a rotor 160. The rotor 160 is fixedly connected to the rotating shaft 150, which drives the rotor 160 to rotate. The rotor 160 is disposed on the valve seat 116 and cooperates with the valve seat 116 to define a service waterway, a brine suction waterway, a bypass waterway, a backwash waterway, and a replenishment waterway. The drive unit 142 is connected to the valve body 110, and the rotating shaft 150 is rotatably connected to the valve body 110. The rotating shaft 150 is in transmission connection with the drive unit 142. 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 drives the rotating shaft 150 to rotate, which drives the rotor 160 to rotate, causing the rotor 160 to cooperate with the valve seat 116 to define corresponding waterways. For example, the movable plate 160 is rotated so that the movable plate 160 is matched with the tank inlet cavity 131. Thus, the first water inlet cavity 130, the second water inlet cavity 132, the movable plate 160 and the tank inlet cavity 131 jointly define a service waterway.

[0313] As shown in FIG5 , according to some embodiments of the present application, the valve body 110 includes a valve body portion and a valve plug cover 118 . The valve cavity 111 is provided in the valve body portion, and one side of the valve cavity 111 is open. The rotating shaft 150 is provided through the valve cavity 111, one end of the rotating shaft 150 is located inside the valve cavity 111, and the other end of the rotating shaft 150 is located outside the valve cavity 111. The gear assembly 143 and the drive motor are both located outside the valve cavity 111. The gear assembly 143 is formed by meshing the drive gear 1432 with the transmission gear, and the drive motor is the drive portion 142. The valve plug cover 118 is provided on the open end of the valve cavity 111 to seal the valve cavity 111. The rotating shaft 150 is provided on the valve plug cover 118, and the gear assembly 143 is located outside the valve cavity 111. As shown in FIG6 , a receiving groove 117 is provided on the valve body portion, and the drive motor is suitable for being received in the receiving groove 117. The valve plug cover 118 is suitable for covering the receiving groove 117 , and the output shaft of the driving motor passes through the valve plug cover 118 , and one end of the driving motor abuts against and is fixedly connected to the valve plug cover 118 .

[0314] As shown in FIG5 , 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, and the vertical shaft 151 is disposed in the valve cavity 111. One end of the vertical shaft 151 is fixedly connected to the driven gear 1431. The connecting disc 152 is disposed 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 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.

[0315] As shown in Figures 5 and 11, 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.

[0316] Both the first and second clips can be multiple, with the multiple first clips spaced apart along the circumferential direction of the connecting disk 152, and the multiple second clips spaced apart along the circumferential direction 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 and the second positioning portion are adapted to locate the relative positions of the movable plate 160 and the connecting disk 152 in the circumferential direction, thereby preventing misalignment of the rotating shaft 150 and the movable plate 160 during assembly. For example, as shown in Figure 11, 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 locate the movable plate 160 and the connecting disk 152, so that their relative positions in the circumferential direction are uniquely determined, facilitating assembly.

[0317] As shown in FIG5 , 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 . The control plate 119 is provided with a Hall sensor 1191 , and the gear assembly 143 is provided with a magnetic member. The Hall sensor 1191 is used to sense the position of the magnetic member. Thus, the drive motor 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.

[0318] As shown in FIG5 , in some embodiments, there may be multiple Hall sensors 1191, spaced apart along the circumference of the rotating shaft 150. The locations of the multiple 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 to a position closest to one of the Hall sensors 1191, the valve core assembly 140 switches to the corresponding position. For example, the location of one of the multiple Hall sensors 1191 corresponds to the service position. When the magnetic member moves to a position closest to the 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 can overlap to improve 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 5 , the water softener 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 and control board 119 are housed within the mounting space.

[0319] As shown in Figures 5, 8, and 9, 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 the rotation of the stator 170, thereby extending the service life of the valve body 110. The stator 170 is also easily replaceable, facilitating subsequent maintenance. As shown in Figure 8, the stator 170 is provided with a fixed bypass hole 171 corresponding to 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. Stator 170 is also provided with a fixed water inlet hole 173 and a fixed tank inlet hole 174. Fixed water inlet hole 173 communicates with the second water inlet chamber 132, while fixed tank inlet hole 174 communicates with the tank inlet chamber 131.

[0320] As shown in Figures 5 and 10, 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 that of the top surface of the valve seat 116. This allows the stator 170 and the valve seat 116 to be sealed to prevent water seepage, and also allows the stator 170 to be fixed relative to the valve seat 116 to prevent the stator 170 from sliding along 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.

[0321] As shown in Figures 6 and 9 , 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 Figures 6 and 9 , the first fixing portion 1111 is a protrusion, and the second fixing portion 172 is a groove.

[0322] 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.

[0323] For example, as shown in FIG6 , there are three first fixing portions 1111 , all of which are protrusions. As shown in FIG9 , 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.

[0324] As shown in Figures 11 and 12 , 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 400 via the tank inlet pipe 114. The raw water contacts the resin, reducing the concentration of calcium and magnesium ions, forming soft water. The soft water flows from the outlet of the resin tank 400 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.

[0325] 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 6, 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.

[0326] As shown in FIG11 , according to some embodiments of the present application, a water inlet channel 163 is provided on the surface of the rotor 160 facing away from the valve seat 116. The water inlet channel 163 connects the dynamic water inlet hole 161 with the first water inlet chamber 130 to guide water in the first water inlet chamber 130 into the dynamic water inlet hole 161. In some embodiments, a communication port 164 is further provided on the surface of the rotor 160 facing away from the valve seat 116. The communication port 164 is used to connect the water inlet channel 163 with the first water inlet chamber 130. The communication port 164 is provided at the edge of the rotor 160 and extends in the radial direction of the rotor 160. The water inlet channel 163 has multiple communication openings 164 communicating with the first water inlet chamber 130. These multiple communication openings 164 are spaced apart along the circumference of the rotor 160. Some of these communication openings 164 communicate 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 openings 164 can be evenly distributed along the circumference of the rotor 160 to evenly 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. As shown in Figure 11, 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.

[0327] As shown in Figures 19-22, Figure 19 is a schematic diagram of the structure of the water softener 100 when the valve core assembly 140 is in the service position. Figure 20 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 21 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 22 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.

[0328] 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 channel 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 through the fixed tank inlet hole 174. The dynamic water inlet hole 161 communicates with the first water inlet chamber 130 through the water inlet channel 163 and the connecting port 164. The dynamic bypass hole 162 communicates with the second water inlet chamber 132 through the fixed water inlet hole 173. Thus, raw water is transported to the first and second water inlet chambers 130, 132, through the water inlet pipe 112. The raw water in the first water inlet chamber 130 can flow through the connecting port 164 into the water inlet channel 163 (in the direction of flow indicated by arrow 1 in Figures 19 and 20), and then into the dynamic water inlet hole 161 (in the direction of flow indicated by arrow 2 in Figures 19 and 20). Raw water in second water inlet chamber 132 flows through fixed water inlet hole 173 and dynamic bypass hole 162 into water inlet channel 163, and then into dynamic water inlet hole 161. After flowing into dynamic water inlet hole 161, the raw water flows through fixed tank inlet hole 174 into tank inlet chamber 131. The raw water in tank inlet chamber 131 is then transported to the inlet of resin tank 400 via tank inlet pipe 114.

[0329] As shown in Figure 22, the inlet and outlet of the resin tank 400 are both located at one end of the resin tank 400. A central tube 410 is provided in the resin tank 400. One end of the central tube 410 is connected to the outlet of the resin tank 400, and the other end of the central tube 410 is connected to the resin tank 400. The resin is stored in the resin tank 400 and is located outside the central tube 410. Raw water enters the resin tank 400 from the inlet (as shown by the flow direction of arrow 2 in Figure 22) and comes into contact with the resin. The resin absorbs the calcium and magnesium ions in the raw water to form soft water. The soft water reaches the other end of the resin tank 400, flows from the central tube 410 to the outlet of the resin tank 400, and flows to the water outlet pipe 113 through the tank outlet pipe 115 and the bypass check valve 137. The soft water output by the water outlet pipe 113 is transported to the user end through a pipeline.

[0330] As shown in Figures 23 and 24, Figure 24 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. 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 and is delivered to the user end through a pipeline. As shown in Figure 24, during this process, the raw water does not pass through the resin tank 400. This allows for flexible water supply according to user needs during use and reduces resin consumption.

[0331] As shown in FIG6 , 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 500. As shown in FIG12 , the rotor 160 is provided with a dynamic salt absorption water diversion hole 165. The dynamic salt absorption water diversion hole 165 is a blind hole 168 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 extends through the rotor 160 along its thickness and 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.

[0332] As shown in Figures 6 and 12 , 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.

[0333] Referring to Figures 25 to 29 , the valve core assembly 140 is in the salt absorption position. Figure 25 is a schematic diagram of the structure of the water softener 100; Figure 26 is a schematic diagram of the internal structure of the valve chamber 111, wherein the rotor 160 and stator 170 are not shown, and the arrows in the figure indicate the direction of water flow; Figure 27 is a schematic diagram of the relative position of the rotor 160 and stator 170; Figure 28 is a schematic diagram of the relative position of the rotor 160 and stator 170 from another perspective, with the arrows in the figure indicating the direction of water flow; and Figure 29 is a cross-sectional view of the water softener, with the arrows in the figure indicating the direction of water flow.

[0334] 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.

[0335] 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 27 and 28). 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 28); the other part of the raw water flows into the bypass chamber 133 through the fixed bypass hole 171, and the raw water in the bypass chamber 133 is output through the water outlet pipe 113 to be provided to the user.

[0336] According to some embodiments of the present application, the salt absorption chamber 134 is selectively connected to the salt tank 500. When in the salt absorption position: the salt absorption chamber 134 is connected to the salt tank 500, the soft water valve 100 is in the salt absorption mode, and the salt water in the salt tank 500 and the raw water in the salt absorption chamber 134 are transported to the resin tank 400 to clean and restore the resin, so that the resin recovers its adsorption capacity; the salt absorption chamber 134 is disconnected from the salt tank 500, and the soft water valve 100 is in the slow wash mode. At this time, the salt tank 500 stops providing salt water, and the raw water in the salt absorption chamber 134 is transported to the resin tank 400 to flush the resin tank 400 to flush the salt in the resin. As shown in Figure 7, in some embodiments, the soft water valve 100 further includes a jet pipe 181, in which an ejector 240 is provided. The jet pipe 181 is connected to the valve body 110 and is connected to the salt absorption chamber 134. The jet tube 181 is connected to both the salt tank 500 and the resin tank 400. When the salt absorption chamber 134 is connected to the salt tank 500, the ejector 240 can transport the water in the salt absorption chamber 134 and the brine in the salt tank 500 to the resin tank 400; when the salt absorption chamber 134 is disconnected from the salt tank 500, the jet tube 181 can transport the water in the salt absorption chamber 134 to the resin tank 400 to flush the resin.

[0337] As shown in FIG29 , according to some embodiments of the present application, the water softener valve 100 further includes a wastewater discharge line 2107. The wastewater discharge line 2107 selectively connects to the tank inlet pipe 114, which in turn connects to the inlet of the resin tank 400. Thus, the wastewater discharge line 2107 communicates with the resin tank 400 via the tank inlet pipe 114. In the salt absorption position, the wastewater discharge line 2107 connects to the tank inlet pipe 114. Wastewater generated during resin cleaning in the salt absorption and slow wash modes can be discharged through the wastewater discharge line 2107. In some embodiments, the adapter assembly 200 includes a wastewater discharge control assembly 250 for controlling the connection between the wastewater discharge line 2107 and the tank inlet pipe 114. Specifically, as shown in FIG29 , the wastewater discharge control assembly 250 is located at the connection between the wastewater discharge line 2107 and the tank inlet pipe 114. A drive block 1433 is provided on the bottom surface of the driven gear 1431. When the valve core assembly 140 is located at the salt absorption position, the driving block 1433 pushes the pressure rod to move, so that the sewage discharge path 2107 is connected to the tank inlet pipe 114.

[0338] As shown in Figure 29, the jet tube 181 is connected to the central tube 410 of the resin tank 400. When the soft water valve 100 is in salt absorption mode, the pressure rod is in the open state. A portion of the raw water input to the soft water valve 100 is transported to the jet tube 181 via the salt absorption line (flow direction indicated by arrow 2 in Figure 29). The jet tube 181 mixes the salt water and raw water and transports it to the outlet of the resin tank 400. The mixed salt water flows through the central tube 410 to the other end of the resin tank 400 and contacts 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 400 and is discharged through the sewage discharge line 2107. The remaining raw water input to the soft water valve 100 is transported to the outlet pipe 113 via the bypass waterway (flow direction indicated by arrow 3 in Figure 29) to be provided to the user. As shown in Figure 30 , 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 provided by brine tank 500. This is not detailed here. In the brine absorption position, the softening valve 100 provides water through the brine absorption line and the bypass water line. This allows water to be provided to the user simultaneously while the resin is being cleaned and reduced, ensuring uninterrupted water supply and preventing any disruption to user water usage.

[0339] As shown in Figures 6 and 12 , 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 410 of the resin tank 400. In the example of Figure 6 , the backwash chamber 136 and the brine absorption chamber 134 are spaced apart in the radial direction of the valve seat 116. In the example of Figure 12 , 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.

[0340] In the backwash position, the backwash chamber 136 communicates with the dynamic bypass hole 162 to define a backwash water path; the dynamic backwash hole 166 communicates with the 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 400 to backwash the resin, flush out broken resin, and increase the spacing between the resin particles. This ensures that the resin particles are fully exposed to the raw water in the service position, enhancing the adsorption of calcium and magnesium ions in the raw water. The remaining 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 2107 communicates with the resin tank 400 to discharge wastewater generated during the backwash process.

[0341] As shown in Figures 31 to 34, the valve core assembly 140 is in the backwash position. The arrows in the figures indicate the direction of water flow. Figure 31 is a schematic diagram of the structure of the water softener 100; Figure 32 is a schematic diagram of the relative positions of the rotor 160 and stator 170; Figure 33 is a schematic diagram of the relative positions of the rotor 160 and stator 170 from another perspective; and Figure 34 is a cross-sectional view of the water softener.

[0342] 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 to the first water inlet chamber 130 and the second water inlet chamber 132 via the fixed water inlet hole 173. Raw water is delivered to the first water inlet chamber 130 and the second water inlet chamber 132 via the water inlet pipe 112 (flow direction indicated by arrow 1 in FIG. 34 ). 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. 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.

[0343] 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 Figure 34), and then flows into the central tube 410 of the resin tank 400 through the backwash pipe 182. The raw water is transported to the other end of the resin tank 400 through the central tube 410 to flush the resin. At the backwash position, the sewage discharge path 2107 is connected to the tank inlet pipe 114 of the resin tank 400. The sewage generated after the raw water flushes the resin flows out through the inlet of the resin tank 400 and is discharged from the sewage discharge path 2107. In some embodiments, a plurality of push blocks are provided on the driven gear 1431. When the valve core assembly 140 moves to the backwash position, one of the push blocks pushes the pressure rod, so that the sewage discharge path 2107 is connected to the tank inlet pipe 114. The raw water flowing to the dynamic backwash hole 166 flows into the bypass chamber 133 through the fixed bypass hole 171 (as shown by arrow 3 in Figure 34), and is then output from the water outlet pipe 113 to be provided to the user. Therefore, during the backwash process, the water softener can continuously supply water.

[0344] 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 salt absorption check valve 260 is provided between the water supply pipe and the jet pipe 181. The salt absorption check valve 260 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 400. For example, in the example of Figure 29, 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 the pressure in the water supply pipe, and the jet pipe 181 is connected to the resin tank 400, allowing raw water to flow from the jet pipe 181 to the resin tank 400.

[0345] In the water replenishment position, the dynamic water inlet 161 is connected to both the water replenishment chamber and the salt absorption chamber 134. The pressure differential between the water replenishment pipe and the jet pipe 181 is zero. The salt absorption check valve 260 blocks the connection between the jet pipe 181 and the resin tank 400, while the jet pipe 181 remains connected to the salt tank 500. The salt absorption chamber 134 replenishes water into the salt tank 500 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 500 typically contains salt, and it is necessary to maintain a "salt-only" state within the salt tank 500 to prevent the salt tank 500 from failing to provide salt water during use, resulting in resin reduction failure. In the water replenishment position, water is replenished to the salt tank 500 through the water replenishment waterway to dissolve the salt within the salt tank 500 and replenish the salt water.

[0346] 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.

[0347] As shown in Figures 35-38, 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 35 is a schematic structural diagram of the soft water valve 100; Figure 36 is a schematic diagram of the relative positions of the movable plate 160 and the fixed plate 170; and Figure 37 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.

[0348] Raw water is delivered to the first and second water inlet chambers 130 and 132 via 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 salt absorption chamber 134 through the fixed salt absorption hole 175 and then into the jet pipe 181. This balances the pressure exerted by the water in the backwash pipe 182 on the salt absorption check valve 260 with the pressure exerted by the water in the jet pipe 181 on the salt absorption check valve 260. The salt absorption check valve 260 blocks the connection between the jet pipe 181 and the resin tank 400, while maintaining communication between the jet pipe 181 and the salt tank 500. Thus, the water in the salt absorption chamber 134 is transported to the salt tank 500 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.

[0349] 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 FIG6 , the tank inlet chamber 131 , the salt absorption chamber 134 , and the bypass chamber 133 are arranged sequentially in the circumferential direction of the valve seat 116 , with the service position and the salt absorption position adjacent to each other. As shown in FIG20 and FIG27 , the valve core assembly 140 can be switched from the service position to the salt absorption position by rotating a certain angle counterclockwise as shown in the figure. As shown in Figure 40, within the mixed water range, 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 400 via the service waterway to displace calcium and magnesium ions in the raw water, producing soft water. The soft 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 range, the water output from outlet pipe 113 is a mixture of soft water 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.

[0350] As shown in Figures 39 to 42, the valve core assembly 140 is located within the mixed water zone. Figure 39 is a schematic diagram of the structure of the water softener 100, with arrows indicating the direction of water flow. Figure 40 is a schematic diagram illustrating the relative positions of the rotor 160 and stator 170, with arrows indicating the direction of water flow. Figure 41 is a schematic diagram illustrating the relative positions of the rotor 160 and stator 170 from another perspective. Figure 42 is a cross-sectional view of the water softener.

[0351] 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.

[0352] A portion of the raw water in the water inlet flows through fixed inlet hole 174 into inlet chamber 131 (as indicated by arrow 1 in Figures 40 and 41). The raw water in inlet chamber 131 is then transported to the inlet of resin tank 400 via inlet pipe 114 (as indicated by arrow 1 in Figure 42). The raw water then enters resin tank 400 and comes into contact with the resin, displacing calcium and magnesium ions, forming soft water. The soft water is then discharged through central pipe 410 and the outlet of resin tank 400, and then transported to outlet pipe 113 via outlet pipe 115 (as indicated by arrow 1' in Figure 42).

[0353] Another part of the raw water in the water inlet flows into the dynamic salt absorption water distribution hole 165 through the fixed salt absorption connecting hole 176 and the salt absorption connecting cavity 135, and then flows into the bypass cavity 133 (as shown by the flow direction of arrow 2 in Figure 40 and Figure 41). The raw water in the bypass cavity 133 flows into the outlet pipe 113 (as shown by the flow direction of arrow 2 in Figure 42). In this way, the water in the outlet pipe 113 is a mixture of soft water and raw water. As shown in Figure 41. The rotation angle of the valve core assembly 140 can be adjusted to adjust the

[0354] As shown in FIG9 , the angle between the fixed salt intake hole 175 and the fixed bypass chamber 133 is the mixing angle. In the example of FIG9 , the mixing angle is 35 degrees, but of course, the mixing angle can also be other angles. As shown in FIG20 , when the valve core assembly 140 rotates from the service position in the direction of the arrow to the salt intake position, when the rotation angle is less than the mixing angle, the dynamic salt intake water diversion hole 165 communicates with the bypass chamber 133, and the dynamic salt intake water diversion hole 165 is disconnected from the salt intake chamber 134.

[0355] As shown in Figures 13-15, according to some embodiments of the present application, the adapter assembly 200 also includes an adapter integrated seat 210, and the internal structure of the adapter integrated seat 210 is composed of a first flow path 2101, a second flow path 2102, a mixed salt flow path 2103, a backwash flow path 2104 and a transfer cavity 2105, and the outer peripheral side of the adapter integrated seat 210 corresponding to each flow path is provided with a transfer interface; one end of the first flow path 2101 is connected to the tank inlet pipe 114 through the corresponding transfer interface, and the other end of the first flow path 2101 is connected to the tank inlet pipe 114 through the corresponding transfer interface. It is connected to the resin filling part 420 of the resin tank 400 through the corresponding adapter; one end of the second flow path 2102 is connected to the tank outlet pipe 115 through the corresponding adapter, one end of the mixed salt flow path 2103 is connected to the jet tube 181, and one end of the backwash flow path 2104 is connected to the backwash pipe 182, and the other end of the second flow path 2102, the other end of the mixed salt flow path 2103 and the other end of the backwash flow path 2104 are all connected to the center tube 410 of the resin tank 400 through the adapter cavity 2105. The second flow path 2102, the salt mixing flow path 2103 and the backwash flow path 2104 are all connected to the transfer chamber 2105. The bottom of the transfer chamber 2105 has a connection port, which is used to connect with the central tube 410 of the resin tube, so that the water path enters the central tube 410 through the transfer chamber 2105 when in the salt absorption position (slow washing position), backwash position and water replenishment position, forming a reverse circulation water path in the resin tank 400.

[0356] As shown in Figures 1 and 16, in a specific configuration, the adapter assembly 200 and the resin tank 400 are connected via the water channel assembly 300, that is, the water channel is guided into the resin tank 400 by the water channel assembly 300. In this embodiment, the first flow path 2101, the second flow path 2102, the salt mixing flow path 2103, and the backwash flow path 2104 are all flow channel structures constructed within the adapter integrated seat 210. Each flow path has a respective port formed on the outer peripheral end surface of the adapter integrated seat 210, and each port has a transfer interface, which enables communication with the soft water valve 100 and the water channel assembly 300 through the transfer interface. Specifically, the two ends of the first flow path 2101 are connected to the tank inlet pipe 114 and the water channel assembly 300 respectively through the corresponding transfer interfaces provided on the outer surface of the adapter integrated seat 210, thereby allowing raw water to be introduced from the water inlet pipe 112 of the soft water valve 100 into the resin tank 400 filling portion of the resin tank 400.

[0357] As shown in Figures 13 and 15, the adapter chamber 2105 is a chamber constructed inside the adapter integrated seat 210. The adapter chamber 2105 is connected to the second flow path 2102, the mixed salt flow path 2103 and the backwash flow path 2104. There is a port at the bottom of the adapter chamber 2105, which is connected to the water path assembly 300 or directly connected to the central pipe 410 of the resin tank 400, so that the water path can be directly connected to the central pipe 410 in the resin tank 400 through the adapter chamber 2105, realizing the flow of the reverse circulation water path. During the specific setting, one end of the second flow path 2102, one end of the mixed salt flow path 2103 and one end of the backwash flow path 2104 are all connected to the corresponding interfaces on the soft water valve 100 through corresponding adapter interfaces, so as to realize the connection between different water paths on the soft water valve 100 and the adapter assembly 200. The other end of the second flow path 2102, the other end of the mixed salt flow path 2103 and the other end of the backwash flow path 2104 are all connected to the adapter chamber 2105. The adapter chamber 2105 can realize the connection between multiple water paths and the central pipe 410 of the resin tank 400, so that the water path can flow out from the second flow path 2102 when in the service position, and finally realize the soft water supply through the outlet pipe 113.

[0358] Among them, one end of the mixed salt flow path 2103 is connected to the valve cavity 111 of the soft water valve 100 through the jet tube 181. The movable plate 160 and the fixed plate 170 in the valve cavity 111 can realize water path switching, so that the raw water can enter the mixed salt flow path 2103, and can be mixed with brine in the mixed salt flow path 2103 and enter the central tube 410 of the resin tank 400. The brine entering the central tube 410 can clean the resin particles and realize the regeneration of the resin particles.

[0359] One end of the backwash flow path 2104 is connected to the valve cavity 111 of the soft water valve 100 through the backwash pipe 182. The movable plate 160 and the fixed plate 170 in the valve cavity 111 can realize water path switching, so that raw water can enter the backwash flow path 2104. The backwash flow path 2104 is connected to the central tube 410 of the resin tank 400 through the adapter cavity 2105, so that raw water can enter from the central tube 410 to backwash the resin particles and realize the regeneration of the resin particles.

[0360] It can be understood that the construction of the adapter chamber 2105 enables multiple flow paths to be connected to the central tube 410 of the resin tank 400 through one port of the adapter chamber 2105, reducing the number of ports for connecting each flow path to the central tube 410 of the resin tank 400, realizing the integration of multiple water paths, and reducing the overall space occupied by the water softener.

[0361] In a specific configuration, as shown in FIG13 , one end of the first flow path 2101, the second flow path 2102, the salt mixing flow path 2103, and the backwash flow path 2104 extend in the same direction. Specifically, the first flow path 2101 and the second flow path 2102 are arranged side by side, and the salt mixing flow path 2103 and the backwash flow path 2104 are arranged side by side. It will be appreciated that the first flow path 2101, the second flow path 2102, the salt mixing flow path 2103, and the backwash flow path 2104 extend in the same direction, allowing the softening valve 100 and the adapter assembly 200 to achieve alignment and connection of multiple flow paths through a single alignment, thereby simplifying the flow path connection with the softening valve 100 and facilitating assembly and disassembly. Furthermore, the first flow path 2101 and the second flow path 2102 are arranged side by side, and the salt mixing flow path 2103 and the backwash flow path 2104 are arranged side by side. By grouping and arranging flow paths with approximately the same flow rate side by side, the symmetry of the flow paths of the adapter assembly 200 is improved, thereby improving the operational stability of the adapter assembly 200.

[0362] As shown in Figures 13 and 29 , according to some embodiments of the present application, the adapter assembly 210 further includes a salt intake passage 2106. One end of the salt intake passage 2106 is connected to the salt tank 500, and the other end of the salt intake passage 2106 is connected to the salt mixing passage 2103. The salt intake passage 2106 and the salt mixing passage 2103 are connected at the front end of the adapter chamber 2105. It can be understood that the salt intake passage 2106 is used to provide salt water of a certain concentration to the salt mixing passage 2103, which is then mixed with the raw water in the salt mixing passage 2103 to provide the required salt water concentration for resin regeneration. When salt water is needed for resin regeneration, the salt intake passage 2106 can effectively introduce the salt water into the salt mixing passage 2103, ensuring sufficient mixing and uniform distribution of the salt water. By connecting the salt intake passage 2106 with the salt mixing passage 2103, the salt water supply path is simplified, improving operational convenience and device efficiency.

[0363] As shown in FIG14 , according to some embodiments of the present application, the adapter assembly 200 further includes an ejector 240, which is positioned at the junction of the salt absorption flow path 2106 and the salt mixing flow path 2103 so that the ejector 240 can draw salt water into the salt mixing flow path 2103. It will be appreciated that by positioning the ejector 240 in both the salt absorption flow path and the salt mixing flow path 2103, the ejector 240 provides salt absorption power to the salt absorption flow path 2106 as the raw water passes through the salt mixing flow path 2103, thereby reducing the salt absorption power required for the salt absorption flow path 2106 and simplifying the overall structure of the water softening device. Furthermore, the ejector 240 can mix the salt water in the salt absorption flow path 2106 and the salt mixing flow path 2103 with the raw water, thereby improving the uniformity and efficiency of the salt water mixing, thereby ensuring that the resin can be fully regenerated and enhancing the overall treatment effect.

[0364] According to some embodiments of the present application, a wastewater discharge path 2107 is disposed within the adapter assembly 210 and communicates with the resin filling portion 420 of the resin tank 400 via the first flow path 2101. It is understood that the wastewater discharge path 2107 communicates with the first flow path 2101 to flow to the resin filling portion 420 of the resin tank 400. Since the resin particles in this embodiment are treated in a backwash mode, i.e., a reverse circulation waterway is used to process the resin particles, during resin cleaning and replacement, wastewater after resin cleaning or replacement is discharged from the end of the resin tank 400 where the raw water enters the resin during normal softening. By connecting the wastewater discharge path 2107 with the first flow path 310, the need for a separate wastewater outlet on the resin tank 400 is eliminated, simplifying the overall structure and flow path arrangement of the water softening device and facilitating assembly between the softening valve 100 and the resin tank 400 or the waterway assembly 300 is eliminated.

[0365] In the specific setting, as shown in Figures 3 and 14, the sewage control assembly 250 includes a sewage pressure rod 251, which has an axially arranged extrusion end 2511 and a mating sealing end 2512. The extrusion end 2511 is located in the driven gear 1431 and can cooperate with the driving block 1433 to be pressurized. The mating sealing end 2512 is located in the sewage water path 2107. The extrusion end 2511 is suitable for causing the mating sealing end 2512 to move to open the sewage water path 2107 after being squeezed. In the normal state, the sewage discharge channel 2107 is in a closed state. Only when sewage discharge is required, the sewage discharge channel 2107 will be opened for sewage discharge operation. In this embodiment, in the normal state, the driving block 1433 is not in contact with the extrusion end 2511. When sewage discharge is required, the driven gear 1431 rotates, and the driving block 1433 is abutted against the extrusion end 2511 of the sewage pressure rod 251. When abutting, it can generate thrust on its own center rod body, so that the center rod body moves. After the center rod body moves, the sealing end 2512 can be separated from the sewage discharge channel 2107, so that the sewage discharge channel 2107 is opened. The whole process is controlled by mechanical transmission, which will not be affected by factors such as electromagnetic interference, thereby improving the reliability of the device.

[0366] It is understandable that the sewage pressure rod 251 is disposed in the sewage discharge channel 2107. Under normal circumstances, the sewage pressure rod 251 can close the sewage discharge channel. Only when the sewage discharge channel 2107 needs to be opened will the driving block 1433 be opened to realize the opening of the sewage discharge channel 2107. In this embodiment, the sewage pressure rod 251 can be a conventional sewage pressure rod 251. The conventional sewage pressure rod 251 includes a rod body, and one end of the rod body has a sealing head, that is, the above-mentioned matching sealing end 2512. When it is not necessary to open, the sealing head can achieve the blocking of the sewage discharge channel 2107. When it is necessary to open, the sewage discharge channel 2107 is opened through the action of an external force. As for the specific sewage pressure rod 251, those skilled in the art should be aware of its specific structure, so it will not be further described.

[0367] For example, in a specific application, the position of the driven gear 1431 with the driving block 1433 is configured as a salt absorption position and controlled by a control system. That is, when the control system sends a signal that salt absorption is required, the driven gear 1431 can be rotated, and the driving block 1433 is abutted against the extrusion end 2511 of the sewage pressure rod 251 by rotation, thereby opening the sewage discharge path 2107. When the sewage discharge path 2107 does not need to be opened, the driven gear 1431 is controlled to rotate so that the driving block 1433 is misaligned with the extrusion end 2511 of the sewage pressure rod 251, and the sewage pressure rod 251 can close the sewage discharge path 2107 again.

[0368] It is understood that in this embodiment, the opening of the sewage discharge channel 2107 is achieved by providing a driving block 1433 on the driven gear 1431. The overall structure is simple and efficient, and can quickly respond to achieve rapid opening of the sewage discharge channel 2107. In addition, the opening of the sewage discharge channel 2107 is achieved through mechanical transmission, which has higher reliability and anti-interference ability.

[0369] As shown in FIG3 , in a specific configuration, multiple drive blocks 1433 may be provided, and the drive blocks 1433 are arranged at intervals. In an overall product, sewage discharge is often required in multiple states. In this embodiment, multiple drive blocks 1433 are provided on the driven gear 1431 to enable sewage discharge in different states, thereby improving the applicability of the sewage discharge system in this example.

[0370] As shown in FIG3 , two drive blocks 1433 are provided on the driven gear 1431. The two drive blocks 1433 are located at different positions. By distributing the two drive blocks 1433 at different positions, the two drive blocks 1433 can respectively control the opening of the sewage discharge channel in at least two states. Of course, the number of drive blocks 1433 can also be three, four, etc., and the drive blocks 1433 are usually distributed in different positions to enable the drive blocks 1433 to correspond to different states. The drawings in the specification of this application only illustrate the method of two drive blocks 1433.

[0371] In specific applications, the two drive blocks 1433 have the same structure and the same material. Of course, the two drive blocks 1433 can also have different structures. In some examples, the minimum distances between the multiple drive blocks 1433 and the extrusion end 2511 of the sewage pressure rod 251 are roughly the same. In theory, the minimum distances between the multiple drive blocks 1433 and the pressure rod assembly are equal, but due to processing and assembly, there are often certain errors, so the minimum distances can be roughly the same. It is understandable that this minimum distance can reflect the depth of the action of the sewage pressure rod 251. Generally speaking, the sewage pressure rod 251 has a fixed action depth to achieve complete sealing of the sewage discharge channel 2107. By limiting the equal minimum distance, the sewage discharge channel 2107 can be stably opened when opened, and can ensure that it is opened to a fully open state, thereby improving its opening stability.

[0372] According to one embodiment provided herein, as shown in Figure 3, a lever mechanism 270 is provided between the drive block 1433 and the drain lever 251. Lever mechanism 270 is used to amplify and transmit thrust. Drive block 1433 is mounted on a driven gear 1431, which is connected to the rotating shaft 150 to transmit mechanical energy, causing the movable plate 160 to rotate and switch the waterway. In this embodiment, the provision of lever mechanism 270 increases the service life of the drain lever 251 and reduces the difficulty and cost of maintenance.

[0373] It is understood that the driven gear 1431 meshes with the driving gear 1432 and is connected to the rotating shaft 150, and the direct interaction of the driving block 1433 with the sewage pressure rod 251 makes the driving block 1433 susceptible to damage. This problem is particularly prominent in cases where the driving block 1433 is used for a long time. Once the driving block 1433 is damaged, the driven gear 1431 needs to be disassembled, which is difficult to disassemble and can easily cause damage to the valve core assembly 140 during the disassembly and assembly process. In this embodiment, by providing a lever mechanism 270 between the driving block 1433 and the sewage pressure rod 251, the transmission is carried out through the intermediate lever mechanism 270, which greatly avoids damage to the driving block 1433 and extends the service life of the driving block 1433. Compared with the disassembly and maintenance of the driven gear 1431, the disassembly of the lever mechanism 270 is simpler, and the maintenance difficulty and cost are lower.

[0374] As shown in Figures 14 and 29, according to an embodiment provided by the present application, the adapter assembly 200 further includes a salt absorption check valve 260, which is disposed in the adapter chamber 2105 and at the end of the mixed salt flow path 2103. It is understood that the salt absorption check valve 260 can be a one-way valve, a check valve, or a similar component, which prevents the occurrence of backflow through its working principle to improve the reliability and stability of the water softening device and reduce the possibility of maintenance and failure. At the same time, the use of the salt absorption check valve 260 can ensure the accuracy and continuity of the brine supply, meet the needs of resin regeneration, and improve the overall treatment effect.

[0375] In a specific configuration, a first adapter 220 and a second adapter 230 are provided at the bottom end of the adapter integration base 210. The first adapter 220 communicates with the first flow path 2101, thereby connecting the first flow path 2101 to the resin filling portion 420 in the resin tank 400. The second adapter 230 communicates with the adapter cavity 2105, thereby connecting each flow path to the central tube 410 in the resin tank 400. It can be understood that the coordinated use of the first adapter 220 and the second adapter 230 facilitates the connection between the adapter cavity 2105 and the central tube 410, and between the first flow path 310 and the resin tank 400, thereby improving the flexibility and maintainability of the device.

[0376] As shown in Figures 16-18, according to an embodiment provided by the present application, the water path assembly 300 includes a main body 301, which is connected to the resin tank 400, and the main body 301 includes a first flow channel 310 and a second flow channel 320. The resin tank 400 is located below the first flow channel 310 and the second flow channel 320; the first flow channel 310 has a first connection port 330 for fluid input or fluid output, and the second flow channel 320 has a second connection port 340 for fluid input or fluid output. The first flow path 2101 is connected to the resin filling part 420 in the resin tank 400 through the first connection port 330, and the transfer cavity 2105 is connected to the center tube 410 in the resin tank 400 through the two connection ends. The first flow channel 310 is provided with a first connection port 350 for connecting with the resin filling part 420 of the resin tank 400; the first connection port 330 is fixedly connected to the first flow channel 310, and the two are connected to each other, wherein the first connection port 330 is used for fluid input or fluid output; the second flow channel 320 is provided with a second connection port 360 for connecting with the central tube 410 of the resin tank 400; the second connection port 340 is fixedly connected to the second flow channel 320 tube, and the two are connected to each other, wherein the second connection port 340 is used for fluid input or fluid output. The design of the water channel components must accommodate the switching of the five functional channels in the water softener: water supply, backwash, regeneration, water replenishment, and forward wash. Therefore, the water channel components typically integrate multiple flow channels into a single structure, which undoubtedly requires complex molding dies to construct the multiple flow channels. In this embodiment, two flow channels, namely a first flow channel 310 and a second flow channel 320, are provided with connecting ports 164, namely a first connecting port 350 and a second connecting port 360, respectively, as shown in FIG18. The two connecting ports enable the two flow channels to connect to the resin filling portion 420 and the central tube 410 in the resin tank 400, respectively. The central tube 410 in the resin tank 400 is separated from the resin filling portion 420 surrounding the central tube 410 by its own tube wall. This allows the two connecting ports to connect to different parts of the resin tank 400, thereby enabling the switching of the flow direction in the resin tank 400.

[0377] As shown in Figures 16-18, according to one embodiment of the present application, the water channel assembly 300 includes a main body 301 having a first flow channel 310 and a second flow channel 320. The resin tank 400 is located below the first flow channel 310 and the second flow channel 320, and the soft water valve 100 and the adapter assembly 200 are located above the first flow channel 310 and the second flow channel 320. During operation, the soft water valve 100 needs to react with the resin particles in the resin tank 400. In this embodiment, the resin tank 400 is placed below the flow channel to facilitate the overall layout. The downward and upward flow of the water channel facilitates sufficient contact between the water and the resin particles, improving the treatment effect.

[0378] In a specific example, as shown in Figure 1, the main body 301 is roughly a plate-like structure, the first flow channel 310 and the second flow channel 320 are respectively located on the main body 301, and the first side is the upper surface side of the main body 301, and the second side is the lower surface side of the main body 301. The layout in the vertical direction B realizes a compact layout of the overall structure, and significantly reduces the space occupied in the thickness direction A.

[0379] As shown in Figures 17 and 18, according to one embodiment of the present application, the connection port includes a first connection port 330 and a second connection port 340. The first connection port 330 is in communication with the first flow channel 310, and the second connection port 340 is in communication with the second flow channel 320. The adapter assembly 200 is in communication with the resin filling portion 420 in the resin tank 400 via the first connection port, and the adapter assembly 200 is in communication with the central tube 410 in the resin tank 400 via two connection ends. As can be seen from the drawings and the following description, the first flow channel 2101 is in communication with the resin filling portion 420 in the resin tank 400 via the first connection port 330, and the adapter cavity 2105 is in communication with the central tube 410 in the resin tank 400 via the two connection ends. The first flow channel 310 is provided with a first connection port 350 for connecting with the resin filling part 420 of the resin tank 400; the first connection port 330 is fixedly connected to the first flow channel 310, and the two are connected to each other, wherein the first connection port 330 is used for fluid input or fluid output; the second flow channel 320 is provided with a second connection port 360 for connecting with the central tube 410 of the resin tank 400; the second connection port 340 is fixedly connected to the second flow channel 320 tube, and the two are connected to each other, wherein the second connection port 340 is used for fluid input or fluid output. The design of the water channel components must accommodate the switching of the five functional channels in the water softener: water supply, backwash, regeneration, water replenishment, and forward wash. Therefore, the water channel components typically integrate multiple flow channels into a single structure, which undoubtedly requires complex molding dies to construct the multiple flow channels. In this embodiment, two flow channels, namely a first flow channel 310 and a second flow channel 320, are provided with connecting ports 164, namely a first connecting port 350 and a second connecting port 360, respectively, as shown in FIG18. The two connecting ports enable the two flow channels to connect to the resin filling portion 420 and the central tube 410 in the resin tank 400, respectively. The central tube 410 in the resin tank 400 is separated from the resin filling portion 420 surrounding the central tube 410 by its own tube wall. This allows the two connecting ports to connect to different parts of the resin tank 400, thereby enabling the switching of the flow direction in the resin tank 400.

[0380] In this embodiment, the first flow channel 310 and the second flow channel 320 are respectively used for the input or output of liquid fluids. The input or output is determined by the connected soft water valve 100. It is understood that the soft water valve 100 needs to meet the requirements of both a softening water path during the water softening process and a regeneration path for the resin pellets in the resin tank. For example, during softening, raw water enters the first flow channel 310 through the first connection port 350 and is softened by the resin pellets in the resin tank 400. The treated water then rises through the central tube 410 and is output through the second flow channel 320 and the second connection port 360. In this case, the first connection port 350 is used for fluid input, and the second connection port 360 is used for fluid output. During regeneration, brine enters the second flow channel 320 through the second connecting port 360 and enters the bottom of the resin tank 400 through the central tube 410. The brine entering the bottom can rise along the outer portion of the resin tank 400 to clean the resin particles, and then enters the first flow channel 310 and is output from the first connecting port 350 in the first flow channel 310. At this time, the first connecting port 350 is used for fluid output, and the second connecting port 360 is used for fluid input.

[0381] It can be understood that in this embodiment, the switching between the soft water channel and the regeneration water channel is achieved through two flow channels, which simplifies the structure of the number of flow channels, makes the overall structure simple, and reduces the difficulty of preparation.

[0382] As shown in FIG16 , in a specific configuration, the water channel assembly 300 and the resin tank 400 are both made of plastic material. Plastic material is easy to mold and is conducive to the construction of flow channels and the construction of complex shapes. In addition, the one-piece molding of plastic material can combine plastics of various materials together to form a compact and seamless product.

[0383] In a specific application, as shown in Figure 18, the first connection port 350 is a truncated opening, and the cross-sectional area of ​​the first connection port 350 in the cross-sectional direction of the resin tank 400 is less than or equal to the cross-sectional overlap between the first flow channel 310 and the resin filling portion 420. The waterway, through its connection with the resin tank 400, enables the basic functions of a water softener. That is, raw water can flow through the first flow channel 310 into the resin tank 400 in a forward direction, achieving softening, while salt water can also return from the first flow channel 310 to the salt mixing channel and enter the central tube 410 in a reverse direction, achieving other functions. In this embodiment, the first connection port 350 is opened along the extension direction of the first flow channel 310. As long as the truncation opening does not exceed the corresponding range of the resin tank 400, the size of the first connection port 350 is not restricted, and the distribution of raw water through the first connection port 350 is not affected by the opening size.

[0384] It can be understood that. As shown in Figure 18, in this embodiment, the part of the entity forming the first flow channel 310 spans above the resin tank 400, which makes the first flow channel 310 and the resin tank 400 have intersecting planes in the horizontal direction, and the intersecting planes are the above-mentioned cross sections. That is, part of the entity structure of the first flow channel 310 is located inside the resin tank 400, and the outer portion of the resin tank 400 is the resin filling portion 420 filled with resin particles. The first connection port 350 can open an opening of any size on the entity part located in the resin tank 400, so that it is not limited by the inner diameter of the first flow channel 310, so that even on the first flow channel 310 with a smaller inner diameter, it can open a larger first connection port 350 size along its own extension direction, thereby meeting the high-quality water distribution effect.

[0385] Specifically, in this embodiment, since part of the wall forming the first flow channel 310 spans above the resin tank 400, and a first connecting port 350 is opened on the wall above the resin tank 400, the part of the wall facing the resin tank 400 can be a notch structure. At this time, the size of the first connecting port 350 is equal to the overlapping part of the wall and the resin filling part 420 in the resin tank 400, which increases the contact area between the first connecting port 350 and the resin filling part 420 of the resin tank 400, thereby improving the water distribution effect of the raw water entering the resin tank 400 from the first connecting port 350, enabling the water body to fully contact with the resin, thereby improving the softening efficiency and softening quality of the water body.

[0386] According to an embodiment provided by the present application, a plurality of resin tanks 400 are connected to the main body 301. The plurality of resin tanks 400 are arranged in parallel and spaced apart along the extension direction of the first flow channel 310 or the extension direction of the second flow channel 320. The first connection port 330 and the second connection port 340 are both located on the same one of the plurality of resin tanks 400. The resin tank 400 is used to load resin, and the amount of resin loaded will directly affect the water quality treatment effect. In the related art, due to the influence of the assembly method, etc., it is usually set as one resin tank 400. If a resin tank 400 wants to load more resin particles, it needs to have a larger volume, which makes the entire component occupy a large space in the width direction, thereby making the overall structure complex and not conducive to installation. In this embodiment, the method of multiple resin tanks 400 can make it narrower in the width direction while having the same volume, which can facilitate the assembly of components.

[0387] In the specific configuration, as shown in Figures 1 and 18, in this embodiment, there are two resin tanks 400, which are arranged in parallel. When determining the number of resin tanks 400, the water treatment capacity requirements of the entire waterway plate and the design of the overall structural space occupancy are generally taken into consideration. Therefore, in some specific designs, three, four, or more resin tanks 400 may be selected. It is understood that when adding resin tanks 400, the flow channel will be arranged in the longitudinal direction to achieve communication between the resin tanks 400 and the flow channel to form a waterway. The drawings in the embodiment description of this application only specifically illustrate the example of two resin tanks 400.

[0388] As shown in Figure 17, the first flow channel 310 and the second flow channel 320 both extend in a straight horizontal direction. Correspondingly, the resin tank 400 is arranged in parallel along the horizontal straight direction. The fluids in the first flow channel 310 and the second flow channel 320 can enter the resin tank 400 for processing, and then be output or input through the first connection port 330 and the second connection port 340 to realize positive circulation water flow direction or reverse circulation water flow direction.

[0389] In specific configuration, as shown in Figure 1, the first connection port 330 and the second connection port 340 are each provided with a quick-insert socket, each of which is provided with a quick-insert plug. The first connection port 330 and the second connection port 340 are both connected to the adapter assembly 200 via the quick-insert plug. Typically, a water softener is installed in a relatively confined space, making assembly and disassembly difficult. In this embodiment, a quick-insert connection is used to facilitate assembly and disassembly.

[0390] In specific configurations, there are various types of quick-connect connectors, such as quick connectors, quick rotary connectors, quick clamp connectors, and compression connectors commonly used in pipe connections. In this embodiment, a socket is provided on the first connection port 330, a connector is provided on the adapter assembly 200, and an annular groove is provided on the connector. The connector is inserted into the first connection port 330, and then inserted into the socket via a snap-fit ​​piece. A portion of the snap-fit ​​piece is located within the annular groove, thereby achieving a quick-connect connection between the adapter assembly 200 and the connection port. When in operation, the snap-fit ​​piece is located within the groove to achieve snap-fit ​​connection. When disassembly is required, the snap-fit ​​piece can be removed to complete disassembly, simplifying the entire assembly and disassembly process.

[0391] As shown in Figures 16 and 18 , according to one embodiment of the present application, a resin tank 400 is integrally formed with a water channel assembly 300. The resin tank 400 comprises a tank body and a cover. The tank body has a receiving cavity and an installation opening communicating with the receiving cavity. The cover is positioned over the installation opening to connect the cover and tank body. After the tank body 400 and the water channel assembly 300 are integrally formed, the upper portion of the tank body and the water channel assembly 300 form a single-piece structure. To facilitate installation of the water distributor and loading of resin pellets, a cover is provided, which seals the resin tank 400.

[0392] The tank body is generally hollow and cylindrical, with a holding cavity formed within it. The holding cavity is the primary component of the resin tank 400 assembly, used to store the resin. Depending on the application, the holding cavity can be designed to have various shapes and sizes to accommodate varying resin volumes and performance requirements, and is not specifically limited here.

[0393] It is understandable that the resin tank 400 assembly may include one or more tank bodies, which are arranged in parallel. For ease of installation, the installation openings of the tank bodies are aligned and arranged toward the same side.

[0394] In specific applications, a tank mouth is provided on the end face of one end of the tank body, and the tank mouth end is integrally formed with the water channel assembly 300. The tank mouth is used to allow and control the flow of fluid into and out of the accommodating cavity. The size and shape of the tank mouth can be adjusted according to actual needs to optimize the flow properties of the resin. At the same time, a connecting port 164 connected to the tank mouth is provided on the water channel plate or the pump body, thereby realizing water channel connection between the tank body and the water channel plate or the pump body; the tank body is provided with an installation opening at the end away from the water channel assembly 300. On the one hand, the installation opening can facilitate the setting of the forming process of the tank body, and on the other hand, it can facilitate the assembly and setting of other components of the tank body, such as a water distributor. The tank body is provided with bolt holes on the outer periphery of the end where the installation opening is provided.

[0395] As shown in Figure 18, the cover is positioned over the mounting opening to seal the mounting opening and ensure relative sealing of the accommodating cavity. The cover is axially connected and secured to the tank body via screws and other fasteners. It is understood that during use, the resin tank 400 assembly requires a certain pressure to propel the internal softening flow path. Therefore, when the resin tank 400 assembly is in an axially positioned tank opening or axially positioned accommodating cavity, a force will be exerted between the cover and the tank body during operation. In the presence of unstable water pressure and the repeated application of this force, the bolted connection ensures a stable connection between the cover and the tank body.

[0396] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment drives the transmission mechanism 141 through a driving device. The transmission mechanism 141 can control the valve core assembly 140 to control the water path switching on the one hand, and can control the opening of the sewage path 2107 in the adapter assembly 200 through the cooperation of the transmission mechanism 141 and the adapter assembly 200 on the other hand, thereby achieving control of the entire water path, simplifying the control logic, improving the control efficiency, reducing the setting of the device, and reducing the failure rate of the water path control assembly. Furthermore, the sewage control assembly 250 is a sewage pressure rod 251. The sewage pressure rod 251 opens the sewage path 2107 by squeezing with the drive block 1433 on the driven gear 1431. This is achieved through mechanical transmission. The structure of the entire switch is simple, and the reliability and stability are strong.

[0397] According to an embodiment provided by the present application, the adapter assembly 200 has a sewage control assembly 250 and a sewage path 2107. The sewage control assembly 250 is arranged in the sewage path 2107. The sewage control assembly 250 is used to control the on and off of the sewage path 2107. The driving part 142 is suitable for driving the transmission mechanism 141 to control the opening of the sewage path 2107. The transmission mechanism 141 includes a driving gear 1432, a driven gear 1431 and a rotating shaft 150. The driving gear 1432 is arranged at the output end of the driving part 142; the driven gear 1431 is engaged with the driving gear 1432, and the driven gear 1431 has at least one driving block 1433. The driving block 1433 is used to cooperate with the sewage control assembly 250 to realize the opening of the sewage path 2107, and the rotating shaft 150 is connected to the driven gear 1431; wherein, the rotating shaft 150 is connected to the valve core assembly 140 to drive the valve core assembly 140 to control the water path switching. The sewage control assembly 250 opens the sewage discharge path 2107 by interacting with the driver block 1433 on the driven gear 1431. Specifically, when sewage discharge path 2107 needs to be opened, the rotation of the driven gear 1431 causes the driver block 1433 to squeeze the sewage control assembly 250, thereby opening sewage discharge path 2107. For example, in the salt absorption position, the salt absorption path is connected, and the soft water valve 100 can transfer salt water from the salt tank 500 to the resin tank 400. The salt water displaces the calcium and magnesium ions adsorbed on the resin, reducing the resin so that it can continue to adsorb calcium and magnesium ions. The reduced wastewater enters the sewage discharge path 2107 through the adapter assembly 200. At this time, the driver block 1433 squeezes the sewage control assembly 250, opening sewage discharge path 2107 and enabling direct discharge of sewage. This enables a single driver 142 to control both water path switching and the opening of sewage discharge path 2107, simplifying the control logic.

[0398] In a specific configuration, as shown in FIG5 , the drive unit 142 is a drive motor, which is fixedly connected to the valve body 110 and can be fixedly connected to the valve body 110 via screws. The driven gear 1431 is larger than the drive gear 1432. The two gears are meshed, and the drive motor drives the drive gear 1432 to rotate. The drive gear 1432 drives the driven gear 1431 to rotate, and the driven gear 1431 drives the rotating shaft 150 to rotate, which in turn drives the movable plate 160 within the valve core assembly 140 to rotate. The transmission ratio between the drive gear 1432 and the transmission gear is greater than 1, that is, the number of teeth on the drive gear 1432 is greater than that on the transmission gear, thereby amplifying the driving torque and providing sufficient power to drive the rotating shaft 150 and the movable plate 160 to rotate.

[0399] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
