[0154] The above one or more technical solutions in the embodiments of the present application have at least one of the following technical effects:

[0155] Compared to the prior art, which requires the resin tank to be installed inside the shell before the rear cover is connected to the rest of the shell to complete the assembly, resulting in a certain distance between the rear cover and the resin tank, a larger overall shell volume, and a less compact overall structure of the water softener, the water softener of the present application first directly snaps the rear cover to the resin tank during assembly, and then assembles the other parts of the shell. This allows the rear cover, as part of the shell, to directly encapsulate the resin tank at the nearest position outside the resin tank, improving the structural compactness between the rear cover as the shell and the water softening components and reducing the overall spatial volume of the water softener. It also allows the rear cover to be directly connected to the resin tank, improving the secure installation of the rear cover.

The first and second side panels are directly plug-in compatible, and the installation positions of the first and second side panels sandwich the resin tank and the salt tank between them. This allows the first and second side panels, as part of the housing, to directly enclose the resin tank and the salt tank at their outermost positions, thereby improving the compactness of the housing structure and reducing the overall volume of the water softener. Furthermore, compared to bolt-mounted assembly, the direct plug-in connection of at least one of the first and second side panels to the base facilitates disassembly and assembly of the water softener. The direct connection of the salt tank, resin tank, and base enhances the secure installation of the salt tank and resin tank.

[0170] The above one or more technical solutions in the embodiments of the present application have at least one of the following technical effects:

[0171] Compared to the prior art, which requires the resin tank to be installed inside the housing before the rear cover is connected to the rest of the housing to complete the assembly, thereby maintaining a certain distance between the housing and the resin tank, resulting in a larger overall housing volume and a less compact overall structure of the water softener, the water softener of the present application is assembled by first installing the resin tank and the salt tank on the base according to the installation position, and then connecting the first side panel and the second side panel to the base. The first side panel and the second side panel are arranged at opposite sides of the base along the width direction, and at least one of the first side panel and the second side panel is connected to the base by direct plug-in connection. Moreover, the installation position of the first side panel and the second side panel allows the resin tank and the salt tank to be sandwiched between the first side panel and the second side panel. This allows the first side panel and the second side panel, as part of the housing, to directly encapsulate the resin tank and the salt tank at the nearest position outside the resin tank and the salt tank, thereby improving the compactness of the first side panel and the second side panel as the housing structure and reducing the overall spatial volume of the water softener. On this basis, compared to the assembly method of bolt installation, the direct plug-in connection of at least one of the first side panel and the second side panel to the base facilitates the disassembly and assembly of the water softener.

[0275] 1-5 , the present application provides a water softener, which includes a valve assembly 100, an adapter assembly 200, a water path member 300, and a resin tank 400. The valve assembly 100 includes a valve body 110, a valve core 140, a driving portion 142, and a transmission mechanism 141. The valve core 140 and the driving portion 142 are both arranged in the valve body 110. The driving portion 142 is connected to the valve core through the transmission mechanism 141, so that the valve core 140 controls the water path switching under the drive of the driving portion 142; the adapter assembly 200 includes a valve body 110, a valve core 140, a driving portion 142, and a transmission mechanism 141. The valve core 140 and the driving portion 142 are both arranged in the valve body 110. The driving portion 142 is connected to the valve core through the transmission mechanism 141, so that the valve core 140 controls the water path switching under the drive of the driving portion 142; 00 is connected to the valve assembly 100 and is located on one side of the valve assembly 100. The adapter assembly 200 has a sewage discharge channel 2107, and the adapter assembly 200 cooperates with the transmission mechanism 141. The driving unit 142 is suitable for driving the transmission mechanism 141 to control the opening of the sewage discharge channel 2107. The water channel component 300 is connected to the adapter assembly 200 and is used to guide the flow of the water channel. The resin tank 400 is fixedly connected to the water channel component 300 and is used to soften the water flowing through it. When the water softener is in operation, the water channel flowing through the resin tank 400 has different flow directions when different functions are required. The water channel 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 water channel. The water channel 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 water channel. 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.

[0276] 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, and the rotation of the transmission mechanism 141 is capable of driving the valve core 140 to rotate. When the valve core 140 is rotated 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 performed, 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 controlled by a single drive unit 142.

[0277] 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 transmission component can first drive the action of the valve core 140 of the valve assembly, 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 through the cooperation 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.

[0278] In specific applications, raw water is introduced through the valve assembly 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 is output from the valve assembly 100 through the adapter assembly 200. 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.

[0279] As shown in Figures 6 and 7, according to one embodiment of the present application, a valve body 110 of a valve assembly 100 includes a valve chamber 111. The valve body 110 also 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 located within the valve chamber 111. A valve core 140 is disposed on the valve seat 116 and positioned within the valve chamber 111. The valve core 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, when the water softener is in operation, it primarily has a service position, a salt absorption position, a bypass position, a backwash position, and a water replenishment position. Each position corresponds to a waterway, and the different functions of the water softener are achieved by controlling each waterway.

[0280] When specifically set up, the valve assembly 100 is used to control the flow direction of water (including raw water, soft water, sewage, etc.) in the water softener to achieve the corresponding function. As shown in Figure 29, the water softener also includes a salt box 500. As mentioned above, the resin tank 400 is filled with resin particles. The resin particles are used to adsorb 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 valve assembly 100. The salt box 500 contains salt water, and the salt box 500 is connected to the valve assembly 100. The salt box 500 and the resin tank 400 are connected through the valve assembly 100. The salt box 500 is suitable for providing salt water to the resin tank 400 to clean the reducing resin so that the resin can continue to adsorb calcium and magnesium ions. The valve assembly 100 is used to control the flow direction of water. For example, the valve assembly 100 can control the raw water to flow into the resin tank 400 for filtration to reduce the hardness of the water and form soft water.

[0281] 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 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 valve assembly 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.

[0282] In the service position, as shown in Figures 19-22, at least the service waterway is in a connected state, and the valve assembly 100 can transport raw water to the resin tank 400, so that the resin particles can adsorb 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 valve assembly 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 valve assembly 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.

[0283] For example, when flushing a toilet, the impact of water hardness can be ignored, and the user can use raw water for flushing. In this case, the valve core 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 connected. At this time, the valve assembly 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 absorb calcium and magnesium ions, improving the filtration effect. In the water replenishment position, at least the water replenishment water path is connected. The valve assembly 100 is suitable for delivering water to the salt tank 500 to replenish the salt water.

[0284] It can be understood that in this embodiment, the valve core 140 is driven to rotate by the driving unit 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 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.

[0285] As shown in Figures 6 and 7, according to some embodiments provided by the present application, 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 connected to the tank inlet pipe 114, and the water inlet pipe 112 is connected to both the first water inlet cavity 130 and the second water inlet cavity 132. The valve seat 116 includes a bypass cavity 133, which is connected to the water outlet pipe 113 and is separated from the second water inlet cavity 132. The tank inlet cavity 131 is connected to the first water inlet cavity 130 or the second water inlet cavity 132 via the valve core 140. The first water inlet cavity 130, the second water inlet cavity 132, the valve core 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 140 , and is delivered to the inlet of the resin tank 400 through the tank inlet pipe 114 .

[0286] The bypass chamber 133 communicates with either the first water inlet chamber 130 or the second water inlet chamber 132 via the valve core 140. The first and second water inlet chambers 130, 132, valve core 140, and 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 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.

[0287] 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 valve assembly 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 the water in the water outlet pipe 113 from flowing back into the resin tank 400. The connection point 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 valve assembly 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 point 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.

[0288] 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 140 to drive the valve core 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 valve assembly 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.

[0289] 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 fixed to the valve body 110 via screws. The driven gear 1431 is larger than the driving gear 1432. The two gears are meshed, and the drive motor drives the driving gear 1432 to rotate. The driving 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 moving plate 160 within the valve core 140. The transmission ratio between the driving gear 1432 and the transmission gear is greater than 1, that is, the number of teeth on the driving gear 1432 is greater than that on the transmission gear. This amplifies the driving torque, thereby providing sufficient power to drive the rotating shaft 150 and the moving plate 160 to rotate.

[0290] As shown in Figures 5, 11, and 12, according to some embodiments of the present application, the valve core 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, and the rotating shaft 150 drives the rotor 160 to rotate. The rotor 160 is adapted to be attached to the top of the valve seat 116. The driving 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.

[0291] 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 .

[0292] 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.

[0293] 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.

[0294] 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.

[0295] 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.

[0296] 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 element moves to the position closest to one of the Hall sensors 1191, the valve core 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 element moves to the position closest to the Hall sensor 1191, the valve core 140 switches to the service position. The orthographic projections of the motion trajectories of each Hall sensor 1191 and the magnetic element on the control board 119 can overlap to improve the detection accuracy of the Hall sensors 1191. When the valve core 140 switches to the service position, the magnetic element faces the corresponding Hall sensor 1191. As shown in Figure 5, valve assembly 100 also includes a cover 101, which covers and is fixedly connected to valve body 110, providing sealing and protection. A mounting space is defined between cover 101 and valve body 110. The open end of valve seat 116 is located within the mounting space, and the drive assembly and control board 119 are housed within the mounting space.

[0297] As shown in Figures 5, 8, and 9, according to some embodiments of the present application, the valve core 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.

[0298] 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.

[0299] 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.

[0300] 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.

[0301] 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.

[0302] 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.

[0303] 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.

[0304] 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.

[0305] As shown in Figures 19-22, Figure 19 is a schematic diagram of the structure of the valve assembly 100 when the valve core 140 is in the service position. Figure 20 is a schematic diagram of the relative position of the movable plate 160 and the stator 170 when the valve core 140 is in the service position. Figure 21 is a schematic diagram of the relative position of the movable plate 160 and the stator 170 when the valve core 140 is in the service position from another perspective. Figure 22 is a cross-sectional view of the water softener when the valve core 140 is in the service position, with arrows in the figure indicating the direction of water flow.

[0306] When the valve core 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.

[0307] 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.

[0308] As shown in Figures 23 and 24, Figure 24 is a cross-sectional view of the water softener with valve core 140 in the bypass position. 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.

[0309] 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.

[0310] 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.

[0311] Referring to Figures 25 to 29 , valve core 140 is in the salt absorption position. Figure 25 is a schematic structural diagram of valve assembly 100; Figure 26 is a schematic internal structural diagram of valve chamber 111, not showing rotor 160 and stator 170; arrows in the diagram indicate the direction of water flow; Figure 27 is a schematic diagram of the relative positions of rotor 160 and stator 170; Figure 28 is a schematic diagram of the relative positions of rotor 160 and stator 170 from another perspective; arrows in the diagram indicate the direction of water flow; and Figure 29 is a cross-sectional view of the water softener; arrows in the diagram indicate the direction of water flow.

[0312] 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.

[0313] 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.

[0314] 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 valve assembly 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 valve assembly 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 valve assembly 100 further includes a jet tube 181, in which an ejector 240 is provided. The jet tube 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.

[0315] As shown in FIG. 29 , according to some embodiments of the present application, the valve assembly 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 FIG. 29 , 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 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.

[0316] As shown in Figure 29, the jet tube 181 is connected to the central tube 410 of the resin tank 400. When the valve assembly 100 is in the salt absorption mode, the pressure rod is in the open state. A portion of the raw water input to the valve assembly 100 is transported to the jet tube 181 through the salt absorption line (the flow direction shown by arrow 2 in Figure 29). The jet tube 181 mixes the salt water and raw water and transports them 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 from the sewage discharge line 2107. Another portion of the raw water input to the valve assembly 100 is transported to the outlet pipe 113 through the bypass waterway (the flow direction shown 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, valve assembly 100 provides water through the brine absorption line and 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.

[0317] 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.

[0318] In the backwash position, backwash chamber 136 communicates with dynamic bypass hole 162 to define a backwash water path; dynamic backwash hole 166 communicates with bypass chamber 133 to define a bypass water path. In the backwash position, a portion of the raw water entering valve assembly 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 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 portion of the raw water entering valve assembly 100 is discharged through the bypass water path and outlet pipe 113 to be provided to the user, ensuring uninterrupted water supply. When valve core 140 is in the backwash position, wastewater discharge path 2107 communicates with the resin tank 400 to discharge wastewater generated during the backwash process.

[0319] As shown in Figures 31 to 34, valve core 140 is currently in the backwash position, with arrows indicating the direction of water flow. Figure 31 is a schematic structural diagram of valve assembly 100; Figure 32 is a schematic diagram illustrating the relative positions of rotor 160 and stator 170; Figure 33 is a schematic diagram illustrating the relative positions of rotor 160 and stator 170 from another perspective; and Figure 34 is a cross-sectional view of the water softener.

[0320] In the backwash position, the valve core 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 delivered to the first water inlet chamber 130 and the second water inlet chamber 132 via the fixed water inlet hole 173 through the water inlet pipe 112 (flow direction indicated by arrow 1 in Figure 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.

[0321] 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 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.

[0322] 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 valve assembly 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 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.

[0323] 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.

[0324] 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 working process of the valve assembly 100 in the water supply position are described below using the example that 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.

[0325] As shown in Figures 35-38, the valve core 140 is now in the water replenishment position, and the arrows in the figures indicate the direction of water flow. Figure 35 is a schematic structural diagram of the valve assembly 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.

[0326] 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.

[0327] 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 140 rotates to the mixed water zone, the valve core 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 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 raw water entering valve assembly 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 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.

[0328] As shown in Figures 39 to 42, valve core 140 is located within the water mixing zone. Figure 39 is a schematic diagram of the structure of valve assembly 100, with arrows indicating the direction of water flow. Figure 40 is a schematic diagram of the relative positions of rotor 160 and stator 170, with arrows indicating the direction of water flow. Figure 41 is a schematic diagram of the relative positions of rotor 160 and stator 170 from another perspective. Figure 42 is a cross-sectional view of the water softener.

[0329] 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.

[0330] 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).

[0331] 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 140 can be adjusted to adjust the

[0332] 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 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.

[0333] 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.

[0334] As shown in Figures 1 and 16, when specifically configured, the adapter assembly 200 and the resin tank 400 are connected through the water channel component 300, that is, the water channel is guided into the resin tank 400 by the water channel component 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 in the adapter integrated seat 210. Each flow path has its own port formed on the outer peripheral end surface of the adapter integrated seat 210, and each port has a transfer interface, which is used to achieve communication with the valve assembly 100 and the water channel component 300. Among them, the two ends of the first flow path 2101 are connected to the tank inlet pipe 114 and the water channel component 300 respectively through the corresponding transfer interfaces provided on the outer surface of the adapter integrated seat 210, so that raw water can be introduced from the water inlet pipe 112 of the valve assembly 100 into the resin tank 400 filling portion of the resin tank 400.

[0335] As shown in Figures 13 and 15, the transfer chamber 2105 is a chamber constructed inside the transfer integrated seat 210. The transfer 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 transfer chamber 2105, which is connected to the water path component 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 transfer 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 valve assembly 100 through corresponding adapter interfaces, so as to realize the connection between different water paths on the valve assembly 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 soft water supply through the outlet pipe 113.

[0336] Among them, one end of the mixed salt flow path 2103 is connected to the valve cavity 111 of the valve assembly 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 the 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.

[0337] One end of the backwash flow path 2104 is connected to the valve cavity 111 of the valve assembly 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 chamber 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.

[0338] 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.

[0339] 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 valve assembly 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 valve assembly 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.

[0340] 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.

[0341] 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.

[0342] 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, flowing 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 to the first flow channel 310, the need for a separate wastewater outlet on the resin tank 400 is reduced, simplifying the overall structure and flow path arrangement of the softening device and facilitating assembly between the valve assembly 100 and the resin tank 400 or the waterway component 300 is eliminated.

[0343] 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.

[0344] 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.

[0345] 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.

[0346] 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.

[0347] 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.

[0348] 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.

[0349] 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.

[0350] 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.

[0351] It is understandable that the driven gear 1431 meshes with the driving gear 1432 and is connected to the rotating shaft 150. 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 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.

[0352] 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.

[0353] 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.

[0354] As shown in FIG. 16 to FIG. 18 , according to an embodiment provided by the present application, a plurality of flow channels 303 arranged in parallel are defined in the water channel component 300 , and each flow channel 303 is connected to a corresponding resin tank 400 , so that the plurality of resin tanks 400 are connected in parallel.

[0355] As you can understand, each resin tank 400 has its own independent flow channel 303. After entering the water channel member 300, water flows through different flow channels 303 into each resin tank 400. After being processed within the resin tank 400, it flows out of the water softener for use by the user. This parallel arrangement allows multiple resin tanks 400 to operate simultaneously without interfering with each other. Each resin tank 400 acts as an independent processing unit, capable of performing its own softening treatment, thereby improving the overall processing efficiency and capacity of the water softener.

[0356] By arranging multiple resin tanks 400 in parallel and defining corresponding flow channels 303, the water softener can more flexibly respond to different water treatment requirements. At the same time, maintaining the independent operation of the resin tanks 400 can also prevent the normal operation of the entire system from being affected when a resin tank 400 fails.

[0357] The water channel component 300 includes a main body 301, which is connected to the resin tank 400. 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 end 330 for fluid input or fluid output, and the second flow channel 320 has a second connection end 340 for fluid input or fluid output. The first flow channel 2101 is connected to the resin filling part 420 in the resin tank 400 through the first connection end 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 communicating with the resin filling part 420 of the resin tank 400; the first connection end 330 is fixedly connected to the first flow channel 310, and the two are communicated with each other, wherein the first connection end 330 is used for fluid input or fluid output; the second flow channel 320 is provided with a second connection port 360 for communicating with the central tube 410 of the resin tank 400; the second connection end 340 is fixedly connected to the second flow channel 320 tube, and the two are communicated with each other, wherein the second connection end 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.

[0358] 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, and the input or output is controlled and selected by the valve assembly 100 connected thereto. It is understood that the valve assembly 100 needs to meet the requirements of the softening water path during the water softening process and the regeneration path for the resin particles in the resin barrel. For example, during softening, raw water enters the first flow channel 310 through the first connection port 350 and is softened by the resin particles in the resin tank 400. The treated water rises through the central tube 410 and is output from the second connection port 360 through the second flow channel 320. At this time, 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 connection port 360 and flows through the central tube 410 to the bottom of the resin tank 400. The brine at the bottom rises along the outer portion of the resin tank 400, cleaning the resin particles. It then enters the first flow channel 310 and is discharged through the first connection port 350 within the first flow channel 310. In this case, the first connection port 350 is used for fluid output, while the second connection port 360 is used for fluid input. It will be appreciated that in this embodiment, the two flow channels enable switching between the soft water channel and the regeneration water channel, simplifying the number of flow channels, making the overall structure simpler and reducing the difficulty of manufacturing.

[0359] 16-18 , the resin tank 400 is threadedly connected to the mounting port 302 ; or, the water channel member 300 and the resin tank assembly 20 are integrally formed.

[0360] It is understood that the resin tank 400 is provided with external threads, and the mounting opening 302 is provided with internal threads. Through the threaded connection between the resin tank 400 and the mounting opening 302, the water channel member 300 can be firmly connected to the resin tank 400. This connection method can provide better stability and reliability, ensuring that the water channel member 300 will not loosen or fall off during use.

[0361] As shown in FIG16 , in the specific setting, the water channel component 300 and the resin tank 400 are both made of plastic material. Plastic material is easy to shape 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.

[0362] 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.

[0363] 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.

[0364] 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.

[0365] 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 end 330 and the second connection end 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 and other factors, 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.

[0366] 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.

[0367] 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 end 330 and the second connection end 340 to realize positive circulation water flow direction or reverse circulation water flow direction.

[0368] In a specific configuration, as shown in Figure 1, the first connection end 330 and the second connection end 340 are each provided with a quick-insert socket, within which a quick-insert plug is disposed. The first connection end 330 and the second connection end 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 employed to facilitate assembly and disassembly.

[0369] 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 end 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 end 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.

[0370] 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 member 300. The resin tank 400 comprises a tank body and a cover 430. The tank body has a receiving cavity and an installation opening communicating with the receiving cavity. The cover 430 is positioned over the installation opening to connect the cover 430 to the tank body. After the tank body 400 and the water channel member 300 are integrally formed, the upper portion of the tank body and the water channel member 300 form a single-piece structure. The cover is provided to facilitate installation of the water distributor and loading of resin pellets, and the cover seals the resin tank 400.

[0371] 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.

[0372] 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.

[0373] 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 component 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 the 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 component 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.

[0374] 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. 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, on the one hand, drive the valve core 140 of the valve assembly to control the waterway switching. On the other hand, the transmission mechanism 141 can cooperate with the adapter assembly 200 to control the opening of the sewage path 2107 in the adapter assembly 200, thereby achieving control of the entire waterway, simplifying the control logic, improving the control efficiency, reducing the setting of the device, and reducing the failure rate of the waterway 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.

[0375] 43 to 49 , the water softener provided in the embodiment of the present application further includes a salt box 500 and a housing 600 . The salt box 500 is disposed in front of the resin tank 400 ; the housing 600 is disposed outside the resin tank 400 and the salt box 500 .

[0376] The resin tank 400 is filled with a resin material, which softens the raw water entering it and produces soft water. Users can then obtain the softened water from a water softener. The resin material removes calcium and magnesium ions from the raw water, making the soft water less hard than the raw water. The salt tank 500 is used to store salt. By introducing water (either raw water or softened water) into the salt tank 500, the solid salt in the salt tank 500 dissolves into a salt solution, which is then transported to the resin tank 400. The calcium and magnesium ions in the resin material dissolve in the salt solution and flow out of the resin tank 400 along with the salt solution. The resin material in the resin tank 400 can be cleaned so that it can continue to soften the raw water. A salt inlet 540 is located on the front of the salt tank 500 for replenishing salt.

[0377] As shown in Figures 44 to 46 , the housing 600 is disposed outside the resin tank 400 and the salt tank 500, and the salt tank 500 is disposed in front of the resin tank 400. That is, the salt tank 500 and the resin tank 400 are arranged side by side in a front-to-back arrangement. Compared to a configuration where the salt tank 500 is nested outside the resin tank 400, the front-to-back arrangement of the salt tank 500 and the resin tank 400 can reduce the length and height of the resin tank 400 and the salt tank 500. If the front-to-back direction is the length of the water softener and the left-to-right direction is the width of the water softener, the front-to-back arrangement of the salt tank 500 and the resin tank 400 can reduce the width and height of the water softener, thereby resolving the problem of the water softener being too wide and achieving a thinner water softener. This allows the water softener of this embodiment of the present application to be installed in a small space.

[0378] As shown in Figures 44 and 45 , the housing 600 comprises a plurality of detachably connected panels, which are detachably attached to the exterior of at least one of the resin tank 400 and the brine tank 500. The flexible structure of the housing 600 facilitates the independent removal of each panel. Formed by joining multiple panels, the housing 600 offers a wide variety of shapes, adapting to various resin tank 400 and brine tank 500 structures.

[0379] The shape of the outer side surface of at least one of the resin tank 400 and the salt tank 500 matches the shape of the shell plate. Alternatively, the shell plate is attached to the outer side of at least one of the resin tank 400 and the salt tank 500, reducing the gap between the outer side surface of at least one of the resin tank 400 and the salt tank 500 and the shell plate. This fully utilizes the space within the housing 600, helping to reduce the dimensions of the water softener in all directions and achieve a compact size. For example, the thickness of the water softener can be reduced to achieve an ultra-thin product. The shell plate is attached to the outer side of at least one of the resin tank 400 and the salt tank 500. The degree of attachment is not strictly required. For example, the inner wall of the shell plate substantially fits the outer side surface of at least one of the resin tank 400 and the salt tank 500. "Substantially fit" herein can be understood as completely fitting or having a predetermined gap. The predetermined gap includes gaps caused by processing and assembly errors, and can also be a reserved clearance to ensure assembly and use. The predetermined gap has an upper limit, such as less than 10 mm. Of course, the value of the predetermined gap can be adjusted based on factors such as assembly errors and product requirements.

[0380] The multiple shell plates are detachably connected to each other, and at least one of the resin tank 400 and the brine tank 500 is detachably connected to the shell plates. Adjacent shell plates are fixed to each other, and at least one of the resin tank 400 and the brine tank 500 is fixed to the shell plates. This allows the shell plates to be fixed in multiple ways, providing good fixing stability and high positioning and installation accuracy. The shell plates are plate-like structures with a relatively low thickness, which helps reduce the overall size of the housing 600, such as reducing the width of the housing 600.

[0381] As shown in FIG44 , the housing 600 includes multiple panels, which are positioned at the top, bottom, and sides of the resin tank 400. These panels are referred to as a top cover 610, a base 630, and side panels, depending on their location. The top cover 610 and base 630 are connected via side panels, with at least one side panel inserted between the top cover 610 and base 630. The side panels are secured between the top cover 610 and base 630 by insertion, simplifying installation. The base 630 limits the lower position of the side panels, while the top cover 610 limits the upper position of the side panels. The side panel covers are positioned on the sides of the resin tank 400 and the salt tank 500. At least one of the resin tank 400 and the salt tank 500 contacts and is fixedly connected to the side panels. At least one of the resin tank 400 and the salt tank 500 is removably and fixedly connected to the base 630, while at least one of the resin tank 400 and the salt tank 500 is removably and fixedly connected to the top cover 610.

[0382] The side panel cover is provided on the side of the resin tank 400 and the salt box 500. At least one of the resin tank 400 and the salt box 500 is in contact with and fixedly connected to the side panel. At least one of the resin tank 400 and the salt box 500 is in contact with the side panel and can be positioned with each other. The installation gap between at least one of the resin tank 400 and the salt box 500 and the side panel can also be reduced. At least one of the resin tank 400 and the salt box 500 is also fixedly connected to the side panel, that is, the side panel is directly connected to the side of at least one of the resin tank 400 and the salt box 500, and the installation stability of the side panel is better. "At least one of the resin tank 400 and the salt box 500 is in contact with the side panel" can be understood as at least a portion of the resin tank 400 is in contact with the side panel, and / or at least a portion of the salt box 500 is in contact with the side panel. When the side panel is on the left and / or right side of the resin tank 400 and the salt box 500, the left side (and / or right side) of the resin tank 400 and the salt box 500 should be set to be coplanar as much as possible, and the contact area between the resin tank 400 and the salt box 500 and the side panel should be increased as much as possible to ensure the volume of the resin tank 400 and the salt box 500, and to ensure that the side panel fully contacts the resin tank 400 and the salt box 500, thereby reducing the installation gap and making full use of the space inside the shell 600.

[0383] At least one of the resin tank 400 and the salt box 500 is in contact with and directly fixedly connected to the side plate, including the side plate being in contact with and directly fixedly connected to the resin tank 400, the side plate being in contact with and directly fixedly connected to the salt box 500, and the side plate being in contact with and fixedly connected to the resin tank 400 and the salt box 500 at the same time.

[0384] Taking the example of a side panel directly contacting and securely connected to the resin tank 400, the side panel and the resin tank 400 can be installed with high precision, with a small installation gap between the side panel and the resin tank 400. This allows for a more compact installation of the side panel and the resin tank 400, helping to reduce the size of the water softener in the left-right and front-back directions, as well as the volume of the water softener. Furthermore, the side panel is plugged and secured between the top cover 610 and the base 630, simplifying the installation process and improving installation efficiency. Similarly, the installation of the side panel and the salt tank 500 achieves the aforementioned technical effects and will not be further described here. When the side panel simultaneously abuts and secures the resin tank 400 and the salt tank 500, the left-right side surfaces of the resin tank 400 and the salt tank 500 can be coplanar, thereby reducing the left-right size of the water softener, that is, reducing the width of the water softener. Furthermore, the dual securing of the side panel by the resin tank 400 and the salt tank 500 provides a more effective securing effect, allowing the side panel to be quickly and accurately secured to the sides of the resin tank 400 and the salt tank 500. This results in highly efficient installation and excellent connection stability.

[0385] In the water softener of the present embodiment, the side panels are secured to the base 630 via the top cover 610 of the housing 600. These panels are then secured to the side panels by at least one of the resin tank 400 and the brine tank 500. This allows for multiple fixings of the side panels, resulting in a stable and simple structure. At least one of the resin tank 400 and the brine tank 500 is in contact with the side panels, reducing the installation gap between the resin tank 400 and the brine tank 500 and the side panels. This fully utilizes the space within the housing 600, reduces the left-right and front-back dimensions of the water softener, and makes the water softener thinner, thereby reducing the size of the water softener and achieving a compact size.

[0386] It is understood that at least one of the salt box 500 and the resin tank 400 is connected to the bottom shell plate (the bottom shell plate can be understood as the above-mentioned base 630) via fasteners, at least one of the salt box 500 and the resin tank 400 is clamped to the top shell plate (the top shell plate can be understood as the top cover 610), at least one of the salt box 500 and the resin tank 400 is clamped to the left and right shell plates (the left shell plate can be referred to as the left plate 621, and the right shell plate can be referred to as the right plate 622), the resin tank 400 is clamped to the rear shell plate (the rear shell plate can be referred to as the rear side plate 624), and the salt box 500 is clamped to the front shell plate (the front shell plate can be referred to as the front side plate 623). Shell plates at different positions are all fixed by the resin tank 400 and the salt box 500, and the shell plate fixing method is simple and convenient for disassembly and assembly.

[0387] The top cover 610 may be directly connected to the top of at least one of the resin tank 400 and the brine tank 500, and / or the base 630 may be directly connected to the bottom of at least one of the resin tank 400 and the brine tank 500. The structures of the top cover 610 and the base 630 of the housing 600 are not limited and may be defined as needed.

[0388] It should be noted that the side panels can be understood as the structure of the housing 600 between the top cover 610 and the base 630. The side panels can be arranged on at least one of the front, rear, left, and right sides, and the side panels can have various structural forms.

[0390] It can be understood that, with reference to Figures 45 and 46, the top cover 610 includes a top plate 612 and a lower flange 611 folded downward relative to the top plate 612. The lower flange 611 is covered on the outside of the resin tank 400 and the salt box 500. The lower flange 611 serves to cover and protect the resin tank 400 and the salt box 500. The structure of the top cover 610 is simple, which prevents the core components inside the shell 600 from being exposed to the outside of the shell 600.

[0391] As can be understood, referring to Figures 46 and 47 , at least one lower flange 611 has an inserting slot 613 formed on its inner side, and a protrusion 6227 provided on the side panel. The protrusion 6227 is inserted and fixed in the inserting slot 613. The inserting slot 613 is simple to manufacture, and the top cover 610 and the adjacent side panel are easily assembled. The top cover 610 and the adjacent side panel are inserted into and form an interference fit, ensuring a stable connection between the top cover 610 and the adjacent side panel.

[0392] The left side panel 621, right side panel 622, and one of the rear side panels 624 below the top cover 610 are inserted into the insertion slot 613, thereby positioning and connecting the top cover 610 and the side panel below it. This arrangement is simple and easy to install. Referring to FIG46 , the left and right sides of the top cover 610 are provided with lower flanges 611, each having the same structure. The upper ends of the left and right sides of the housing 600 are provided with bumps 6227. This facilitates the connection of the top cover 610, the left side panel 621, and the right side panel 622, and the structures of the left and right sides are simple.

The first engaging portion 6221 engages with the second engaging portion 700, thereby engaging at least one of the resin tank 400 and the brine tank 500 with the side panel. This engaging engagement between at least one of the resin tank 400 and the brine tank 500 and the side panel provides a simple fixing method, easy installation, and a simple structure.

[0396] It can be understood that one of the first clamping part 6221 and the second clamping part 700 is provided with a first clamping interface, and the other of the first clamping part 6221 and the second clamping part 700 is provided as a clamping block, which is inserted into the first clamping interface and can achieve clamping and fixing of at least one of the resin tank 400 and the salt box 500 to the side plate by pushing the side plate. The structure is simple and the operation is easy.

[0397] Based on the clamping block being provided through the first clamping interface, one of the top cover 610 and the base 630 is plugged and positioned with the side panel. By pushing the side panel to move to the fixed position or the disassembly position, in the fixed position, the first clamping portion 6221 is engaged with the second clamping portion 700, and the other of the top cover 610 and the base 630 is plugged and fixed with the side panel. In the disassembly position, the first clamping portion 6221 is disengaged from the second clamping portion 700. In the process of achieving the clamping connection between the first clamping portion 6221 and the second clamping portion 700 by pushing the side panel, the plugging and fixing of one of the top cover 610 and the base 630 with the side panel can also be completed. In one operation, the side panel can be fixed to multiple components at the same time. The side panel is easy to assemble and disassemble, and has a simple structure. Similarly, the disassembly operation is also simple, which facilitates disassembly and maintenance.

[0398] As will be understood, the clamping block includes a first clamping section and a second clamping section that are connected and form an angle. The first clamping section is connected to the bottom or top end of the second clamping section. The clamping block has an L-shaped block structure, and the second clamping section is connected to at least one of the side panel, the resin tank 400, and the brine tank 500 via the first clamping section. Pushing the side panel upward or downward connects at least one of the resin tank 400 and the brine tank 500, or at least one of the top cover 610 and the base 630, to the side panel, making operation simple and convenient.

[0399] As shown in Figures 46 and 47 , both the resin tank 400 and the salt tank 500 are provided with through-holes to form first latching interfaces. The side panels are provided with first and second latching sections, and multiple latching blocks are provided on the side panels. The multiple latching blocks have identical structures. The side panels are connected to the resin tank 400 via the multiple latching blocks. The resin tank 400 is provided with multiple first latching interfaces, distributed along the height and front-to-back direction of the resin tank 400. The side panels are connected to the salt tank 500 via the multiple latching blocks. The salt tank 500 is provided with multiple first latching interfaces, distributed along the height and front-to-back direction of the salt tank 500.

[0400] In some cases, at least one of the resin tank 400 and the salt box 500 is provided with a first fastening position 900, and at least one of the left side plate 621 and the right side plate 622 is provided with a second fastening position 6229. The first fastening position 900 and the second fastening position 6229 are fixedly connected by fasteners to ensure the installation stability of the left side plate 621 and the right side plate 622.

[0401] As shown in Figures 48 and 49 , the tops of both the resin tank 400 and the salt tank 500 are provided with a first fastening position 900. The left side panel 621 is provided with a second fastening position 6229. The first clamping portion 6221 is provided with a downward opening. The first clamping portion 6221 is inserted into the first clamping interface from top to bottom, so that the first plugging portion 631 and the second plugging portion 625 are plugged together, thereby securing the first fastening position 900 to the second fastening position 6229. Fasteners are then used to securely connect the left side panel 621 to the resin tank 400 and the left side panel 621 to the salt tank 500, ensuring the stability of the left side panel 621. Similarly, the right side panel 622 can also be installed in this manner. It should be noted that after the fasteners of the left and right side panels 621 and 622 are installed, the top cover 610 is secured above the resin tank 400.

[0402] It can be understood that, as shown in reference figure 44, when the side panel is divided into a left side panel 621, a right side panel 622 and a rear side panel 624, the rear side panel 624 is clamped to at least one of the left side panel 621 and the right side panel 622, and the connection method between at least one of the left side panel 621 and the right side panel 622 and the rear side panel 624 is simple and convenient for disassembly and assembly.

[0403] The front side of at least one of the left side plate 621 and the right side plate 622 is positioned with the salt box 500 . The positioning of at least one of the left side plate 621 and the right side plate 622 is convenient and the structure is simple.

[0404] It can be understood that, with reference to FIG47 , at least one of the left side panel 621 and the right side panel 622 is provided with a third clamping portion 6224, and the rear side panel 624 is provided with a fourth clamping portion 6241. One of the third clamping portion 6224 and the fourth clamping portion 6241 is provided with a second clamping interface. The other of the third clamping portion 6224 and the fourth clamping portion 6241 includes a third clamping segment and a fourth clamping segment connected to form an angle. The third clamping segment is connected to the bottom or top end of the fourth clamping segment. The other of the third clamping portion 6224 and the fourth clamping segment 6241 is an L-shaped block structure. The third clamping segment is connected to the left side panel 621, the right side panel 622, or the rear side panel 624. The snap-fit ​​structure is simple and easy to install.

[0405] The matching structure of the third clamping section and the fourth clamping section is the same as the matching structure of the first clamping section and the second clamping section, which can simplify the structure of the side plate and facilitate processing.

[0406] As will be appreciated, the rear side panel 624 is provided with a forward-bent front flange 6242, which is provided with a second snap interface. The third and fourth snap sections are located on the side panel, and the side panel is provided with a first snap section, a second snap section, and a third snap section and a fourth snap section. In other words, the side panel is provided with multiple snaps to facilitate side panel processing. The width of the rear side panel 624 is the same as the width of the resin tank 400, that is, the outer surface of the front flange 6242 is flush with the outer surface of the resin tank 400 at its maximum width.

[0407] The front flange 6242 is provided with a notch, and the fourth clamping portion 6241 is provided at the notch, which can maintain a unified position with the front flanges 6242 on both sides of the notch, that is, the fourth clamping portion 6241 and the front flange 6242 are formed into one piece, further making the structure of the rear side plate 624 compactly integrated and not occupying much other structures and space positions.

[0408] The resin tank 400 is provided with positioning holes, and the rear side panel 624 is provided with a plurality of positioning posts 6243. These posts 6243 are inserted into the positioning holes and are evenly distributed along the height of the rear cover. The posts 6243 are positioned near the two front flanges 6242. In this embodiment, the positioning posts 6243 on the rear side panel 624 are inserted into the corresponding positioning holes on the resin tank 400. The resin tank 400 and the rear side panel 624 are mutually restrained in height and width, thereby achieving positioning and restraining of the rear side panel 624 during installation.

[0409] The resin tank 400 includes a tank body 470 and a mounting plate. The tank body 470 is used to contain resin material. A mounting plate is provided on the side of the tank body 470 facing the rear side plate 624. The mounting plate is connected to the tank body 470 as a whole. The mounting plate extends along the height direction of the tank body 470. The mounting plate corresponds to the rear side plate 624 and is clamped with each other. The positioning hole is provided on the mounting plate, which makes the connection more convenient and the structure more stable and firm.

[0410] The tank body 470 is cylindrical in shape. The mounting plate is further provided with reinforcing ribs, which abut against the rear side plate 624 .

[0411] As shown in reference figure 46, the resin tank 400 includes a tank body 470 and a connecting plate 440. The tank body 470 is used to contain resin material. The connecting plate 440 is connected to the tank body 470 and extends above the tank body 470. A valve assembly is provided on the top of the resin tank 400, and a connecting plate 440 is provided on the left and / or right side of the valve assembly. The connecting plate 440 can protect the valve assembly.

[0412] It is understood that the connecting plate 440 is detachably connected to at least one shell plate, and the connecting plate 440 is separated between the housing 600 and the valve assembly above the tank body 470. Referring to Figure 46, the connecting plate 440 is separated on the left and right sides of the valve assembly, and the connecting plate 440 protects the valve assembly on the left and right sides.

[0413] When connecting plates 440 are provided on both the left and right sides of the tank body 470, the left and right sides of the valve assembly are protected by the connecting plates 440. The top of the connecting plate 440 is flush with the top of the valve assembly, fully protecting the side of the valve assembly and facilitating the direct engagement of the top cover 610 with the connecting plate 440. The outer side of the connecting plate 440 can also be used to contact and position the side panels. The outer side of the connecting plate 440 can fit against the side panels, reducing the installation gap between the side panels and the resin tank 400. The widthwise position of the connecting plate 440 does not exceed the maximum width of the tank body 470.

[0414] The connecting plate 440 and the tank body 470 are integrally formed, and the connection stability between the connecting plate 440 and the tank body 470 is good, and the number of parts of the water softener can be reduced. Of course, the connecting plate 440 and the tank body 470 can also be detachably connected.

[0415] It is understood that both the tank body 470 and the connecting plate 440 are provided with a first snap interface, and the side panels are provided with snap blocks, and both the tank body 470 and the connecting plate 440 are connected to the side panels. The connecting plate 440 can also snap into the top cover 610, and the height of the connecting plate 440 is adapted to the installation height of the top cover 610, facilitating the snap connection between the top cover 610 and the connecting plate 440.

[0416] It is understandable that multiple resin tanks 400 are provided, and multiple resin tanks 400 are arranged in parallel in the front-to-back direction, which does not increase the width of the resin tanks 400, that is, does not affect the width of the water softener, helps to reduce the width of the water softener and form an ultra-thin water softener.

[0417] When multiple resin tanks 400 are provided, the inlets of the cavities of the multiple resin tanks 400 are all connected, and the outlets of the multiple cavities are all connected. The inlets and outlets are all connected to the valve assembly in a switchable manner. Water can be delivered to the inlets of the multiple cavities through the valve assembly, and the water output from the multiple cavities can also be collected by the valve assembly. Of course, the inlets of different cavities can be disconnected, or the inlets of different cavities can be switched between connected and disconnected, and the valve assembly can deliver water to a single cavity, and correspondingly, water can be discharged from that cavity through the valve assembly.

[0418] It is understood that at least two resin tanks 400 are arranged in a front-to-back direction, each having a cavity therein and communicating with each other. The two resin tanks 400 can be fixedly connected (e.g., integrally formed) or independently of each other, depending on the needs.

[0419] It can be understood that the resin tank 400 includes a water channel component arranged on the top of the tank body 470, the water channel component connects the inlet of the cavity with the tank inlet pipe of the valve assembly, and the water channel component connects the outlet of the cavity with the tank outlet pipe of the valve assembly, so as to deliver liquid into the tank body 470 through the valve assembly and also output liquid through the valve assembly.

[0420] It will be appreciated that the bottom shell of at least one of the resin tank 400 and the salt tank 500 is provided with a protrusion 632. The protrusion 632 defines an anti-overflow zone. At least one of the resin tank 400 and the salt tank 500 is located within the anti-overflow zone. The connection between adjacent resin tanks 400 is connected to the water leakage detection member 480, which is recessed inward relative to the housing 600. The protrusion 632 prevents water leakage within the housing 600 from overflowing outside the housing 600, concentrating the water leakage within the anti-overflow zone. This helps the water leakage detection member 480 detect water leakage in a timely manner, allowing the water supply to be stopped promptly based on the leakage, preventing water from leaking out of the water softener, and thus protecting the components within the housing 600.

[0421] A first plug-in portion 631 is provided on the outer side of the protrusion 632 to facilitate the plugging of the side panel and the base 630. The plugging is convenient. The side panel cover is provided on the outer side of the protrusion 632 to protect the protrusion 632, and the integrity of the shell 600 is better.

[0422] The protrusion 632 can surround the outside of the resin tank 400, the outside of the brine tank 500, or the outside of both the resin tank 400 and the brine tank 500. Referring to FIG47 , the base 630 is provided with an anti-overflow area located below the resin tank 400. The anti-overflow area can absorb water leakage from the resin tank 400 and the pipes, valve components, etc. above the resin tank 400.

[0423] Reinforcing ribs 450 are installed in the gap between the two resin tanks 400. These additional ribs 450 distribute and withstand stress generated during operation without affecting the functionality of the tanks 400. This reduces the risk of potential structural damage from vibration or pressure fluctuations, enhances the rigidity and stability of the entire water softener structure, improves space efficiency, and facilitates overall miniaturization. The ribs 450 are angled downward from the inside to the outside of the gap between the two resin tanks 400, helping to divert water downward and quickly detect leaks.

[0424] When multiple resin tanks 400 are provided, a concave area is provided at the connection between two adjacent resin tanks 400, and a water leakage detection member 480 is provided in the concave area. The water leakage detection member 480 does not increase the size of the water softener and fully utilizes the space in the shell 600.

[0425] It is understandable that the salt box 500 and the resin tank 400 are fixed to each other by fasteners and / or snap-fitting, and the salt box 500 and the resin tank 400 have good fixing stability.

[0426] As can be understood, referring to Figures 43 and 46 , a salt adding cover 530 is provided on the front side of the salt box 500. The salt adding cover 530 switches between an open position and a closed position. In the open position, the salt adding cover 530 tilts downward from the front to the back. When the salt adding cover 530 is in the open position, the salt adding port 540 is open, allowing salt to be added to the salt box 500 under the guidance of the salt adding cover 530. When the salt adding cover 530 is in the closed position, the salt adding port 540 is closed. In the open position, the salt adding cover 530 guides salt into the salt box 500. Sliding into the salt box 500, it can reduce the impact force of salt on the bottom of the salt box 500 during salt addition, compared to adding salt from above, thereby helping to improve the stability of the salt box 500.

[0427] The salt adding cover 530 can be opened and closed by rotating with the salt box 500, and the salt adding cover 530 is supported by the salt box 500 so that the salt adding cover 530 is kept in the open position. Of course, the salt adding cover 530 can also be opened and closed by pulling or other methods.

[0428] It can be understood that, with reference to FIG46 , the box body 510 is provided with a guide groove 511, the salt adding cover 530 is provided with a slider 531 slidably connected to the guide groove 511, the side plate of the lining member 520 is provided on the inner side of the guide groove 511, and the slider 531 is limited between the box body 510 and the lining member 520. When the salt adding cover 530 switches between the open position and the closed position, the slider 531 slides in the guide groove 511 to guide and limit the movement path of the salt adding cover 530. When the salt adding cover 530 is opened to the maximum opening, the box body 510 also serves to limit the salt adding cover 530, so that the salt adding cover 530 remains in the open position.

[0429] The salt adding cover 530 is arranged at the front side of the box body 510 . Guide grooves 511 are provided on both the left and right sides of the box body 510 . Sliders 531 are provided on both the left and right sides of the salt adding cover 530 . The left and right sides of the salt adding cover 530 are subjected to balanced force.

[0430] It is understood that the salt box 500 includes a box body 510 and a lining member 520, which are detachably connected. The lining member 520 is inserted above the box body 510 and is independent of the box body 510. The box body 510 is used to hold salt and salt solution. The lining member 520 is arranged above the box body 510 and covers the top of the box body 510. The lining member 520 is snap-fitted to the top cover 610. The lining member 520 and the top cover 610 are installed in a coordinated manner, which can simplify the structure of the box body 510 and adapt the top cover 610 to different shapes.

[0431] The left and right side covers of the lining member 520 are located inside the guide groove 511 to prevent salt particles in the box 510 from entering the guide groove 511 and affecting the sliding movement of the slider 531 within the guide groove 511, ensuring that the salt adding cover 530 can be opened and closed stably. The left side plate 621 and the right side plate 622 are located outside the guide groove 511 to prevent the guide groove 511 and the slider 531 from being exposed to the outside. The left side plate 621 and the right side plate 622 serve to cover the guide groove 511 and protect the slider 531.

[0432] The box body 510 is connected to an overflow pipe 560 , which extends backward from the rear end of the box body 510 so that the overflow pipe 560 is connected to the joint of the rear side plate 624 to discharge overflow water.

[0433] When the water injection fails all the way and the salt valve of the salt well in the salt box 500 fails at the same time, the water level in the salt box 500 keeps rising. When it is higher than the overflow pipe 560, the excess water in the salt box 500 is discharged through the overflow pipe 560 to prevent the water in the salt box 500 from overflowing into the machine and soaking the user's kitchen.

[0434] One end of the overflow pipe 560 has an interference fit with the connecting rod at the rear end of the salt tank 500, while the other end is also interference-fitted and fixed to the connecting rod of the rear side plate 624. The overflow pipe 560 is restrained in the middle of the overflow pipe 560 by the hook structure of the resin tank 400. The connector is fixed to the connecting rod of the rear side plate 624. After-sales maintenance only requires installing one end of the connector on the rear side plate 624 and fixing the other end to the customer's sewer pipe, thus forming a complete connection of the overflow pipe 560.

[0435] In some cases, the box body 510 and the resin tank 400 are detachably connected to ensure a stable connection between the box body 510 and the resin tank 400. The detachable connection may be a snap connection, a fastener connection, or the like.

[0436] The lining member 520 is used to fit the box 510 and can also be used to install control components. The lining member 520 is provided with an installation area for installing control components. The lining member 520 is connected to the control box 800, and the control box 800 is provided with some or all of the control components.

[0437] The outer side surface of the lining member 520 (including the outer side surface in the width direction) is coplanar with the outer side surface of the box body 510. The coplanarity here can be basically coplanar and is not limited to strict coplanarity, such as production error. The outer side surface of the lining member 520 is in contact with the top cover 610, reducing the installation gap between the lining member 520 and the top cover 610, improving the installation accuracy, and helping to reduce the volume of the water softener from an installation perspective. The outer side surface of the lining member 520 is in contact with the side panel, and / or the outer side surface of the salt box 500 is in contact with the side panel, reducing the installation gap between the lining member 520 and the side panel, and also reducing the installation gap between the salt box 500 and the side panel, making full use of the internal space, and helping to reduce the volume of the water softener from an installation perspective.

[0438] Both the box body 510 and the lining member 520 are provided with a first snap-in interface, and the side panels are provided with snap-in blocks. The tank body 470 and the connecting plate 440 are both connected to the side panels. The lining member 520 can also snap-in with the top cover 610. The height of the lining member 520 is adapted to the installation height of the top cover 610, facilitating the snap-in connection between the top cover 610 and the lining member 520.

[0439] It is understandable that the salt box 500 is connected to the valve assembly via a connecting pipe 550 , and the valve assembly opens and closes the connecting pipe 550 and the resin tank 400 . The connecting pipe 550 extends from the top of the resin tank 400 to the salt box 500 .

[0440] As shown in reference figure 48, the resin tank 400 is provided with a limiting portion 460, and the connecting pipe 550 is passed through the limiting portion 460. The limiting portion 460 plays the role of supporting and limiting the connecting pipe 550, guiding and limiting the connecting pipe 550, and ensuring the installation stability of the connecting pipe 550.

[0441] The limiting portion 460 is a hollow hook-type structure, so that the connecting tube 550 can be inserted into the limiting portion 460, preventing the connecting tube 550 from falling off from the limiting portion 460, and also preventing the connecting tube 550 from shaking in the shell 600, ensuring that the connecting tube 550 is arranged according to the preset path.

[0442] The outer side surfaces of the tank body 470 of the resin tank 400, the outer side surfaces of the connecting plate 440, the outer side surfaces of the box body 510 of the salt box 500, and the outer side surfaces of the lining member 520 of the salt box 500 are all coplanar, and the side panels are in contact with the outer side surfaces (strict contact is not required). The outer side surfaces herein can be either the left side or the right side, excluding the front side, rear side, upper side, and lower side surfaces.

[0443] It is understood that at least one of the resin tank 400 and the salt box 500 is fixed to the side plate through an interference fit to ensure installation stability and reduce installation gaps. In combination with the above, the first clamping portion 6221 and the second clamping portion 700 are interference fit, which has a simple structure and good fitting stability.

[0444] It is understood that the lining member 520 is detachably fixedly connected to the resin tank 400. The lining member 520 is doubly fixed by the housing 510 and the resin tank 400. This provides greater installation stability for the lining member 520 and allows for positioning through multiple devices, ensuring accurate positioning of multiple components and improving installation accuracy. When the lining member 520 is connected to the control box 800, the control box 800 is located at the rear side of the salt tank 500 and on top of the resin tank 400.

[0445] In some embodiments, please refer to Figures 16, 18, 50 and 51. According to an embodiment of the present application, the water softener includes a shell 10, multiple resin tanks 400 and a water channel component 300. The shell 10 is formed with a accommodating space, and multiple resin tanks 400 are arranged side by side in the accommodating space along the length direction of the shell 10. The water channel component 300 is arranged in the accommodating space. A plurality of installation ports 302 are provided on one side of the water channel component 300, and the installation ports 302 are connected to the resin tanks 400 one by one.

[0446] In this embodiment, the housing 10 is a rectangular parallelepiped and includes a front panel 11, a rear cover 12, an upper top panel 16, a lower bottom panel, and left and right side panels 21. These panels enclose a space for accommodating a resin tank 400 and a water channel member 300. The resin tank 400 can be filled with ion exchange resin to remove hard ions such as calcium and magnesium from the water, thereby softening the water. The water channel member 300 is connected to the resin tank 400 to provide water inlet and outlet to the resin tank 400.

[0447] It can be understood that in this embodiment, by arranging multiple resin tanks 400 side by side along the length direction of the shell 10, the size of the resin tank 400 in the width direction is reduced when the same volume of resin is filled, and the overall arrangement is rectangular, which facilitates the design of the entire machine into a thinner rectangular shape, improves the space utilization of the water softening device, realizes the miniaturized design of the water softening device, and facilitates the installation of the water softening device in narrow spaces with size restrictions such as cabinets, balconies, and bathroom cabinets, thereby improving the applicability of the water softener.

[0448] In some embodiments, referring to Figures 44 and 45, the water softener further includes a salt tank 500, which is disposed in the accommodating space. The salt tank 500 is connected to the resin tank 400 to supply salt solution to the resin tank 400 during backwashing, and the salt tank 500 is disposed side by side with the resin tank 400 along the length direction of the shell 10.

[0449] It is understandable that salt can be stored in the salt tank 500 of the water softener. When the water softener is in use, after the resin tank 400 has adsorbed enough hardness ions, a backwash operation is required for cleaning. At this time, the salt stored in the salt tank 500 will be dissolved into brine and flow into the resin tank 400 through the backwash valve to regenerate the resin tank 400.

[0450] In an alternative embodiment, as shown in Figures 50-52 , the water softener includes two resin tanks 400 arranged side by side. Each resin tank 400 has a filtration space for filtering water. A salt tank 500 has a salt storage space formed therein. The salt storage space communicates with the resin tanks 400 and provides salt to the resin tanks 400 to regenerate them. In this embodiment, the salt tank 500 and the two resin tanks 400 are arranged side by side along the length of the housing 10, and the salt tank 500 is also snap-fitted to one of the resin tanks 400.

[0451] In this embodiment, on the one hand, two parallel resin tanks 400 are arranged inside the shell 10, so that the two side-by-side resin tanks 400 can work at the same time, which can improve the efficiency of water treatment to a certain extent. In some cases, when one resin tank 400 is undergoing the regeneration process, the other resin tank 400 can continue to provide softened water, thereby achieving continuous water supply and reducing downtime. In addition, the side-by-side arrangement allows the two resin tanks 400 to work independently, that is, if one resin tank 400 needs maintenance or replacement, the other resin tank 400 can still continue to work, ensuring the continuity of water supply and the reliability of the system. Most importantly, the side-by-side arrangement can make more efficient use of space, especially in an environment with limited space. The above layout makes the overall size of the water softener more compact and thinner, making it easy to install and integrate into existing water treatment systems, and can also be used in narrow gap spaces.

[0452] In this embodiment, the salt tank 500 and the resin tank 400 are placed inside the shell 10 of the water softener and arranged along the length direction of the shell 10. This can fully utilize the storage space of the water softener, avoid occupying too much space in the width direction, improve space utilization, and thus improve the applicability of the water softener. The salt tank 500 can be connected to the water softener through reasonable pipes to achieve brine supply, ensuring the normal operation of the water softener.

[0453] In some embodiments, as shown in Figures 50-52, the shell 10 includes a front panel 11 and a rear cover 12, a salt injection window 102 is opened on the front panel 11, and the salt box 500 is arranged on the side of the resin tank 400 facing the front panel 11. The salt box 500 includes a box body 510 and a box cover 520. The box body 510 and the resin tank 400 are arranged side by side. The box body 510 forms a accommodating cavity connected to the salt injection window 102, and the box cover 520 can be rotatably set on the box body 510 to open or close the salt injection window 102.

[0454] It will be appreciated that in this embodiment, the front panel 11 is the side of the water softener that faces the user during use, and the rear cover 12 is opposite the front panel 11 and is the side of the water softener that faces away from the user during use. By providing a salt injection window 102 on the front panel 11, the lid 520 can be rotated to open or close the salt injection window 102, thereby reducing the height footprint of the water softener and its overall size. By configuring the lid 520 to be rotatable to open or close the salt injection window 102, when the lid 520 is in the closed position, the salt injection window 102 is effectively shielded, preventing the salt particles within the salt tank 500 from becoming damp, contaminated, or spilling. When the lid 520 is in the open position, the side of the lid 520 facing the salt injection window 102 can guide salt particles into the salt tank 500 body, thereby buffering the salt particles and preventing them from directly falling into the salt tank 500 body and impacting the inner wall of the salt tank 500 body. Furthermore, the salt particles can be evenly distributed in the salt tank 500 by guiding the salt particles, thereby improving the uniformity of the salt water in the salt tank 500. Furthermore, the lid 520 can be rotated to open and close, and when closed, the space occupied by the water softener can be reduced.

[0455] In some embodiments, referring to FIG. 51 and FIG. 52 , at least one side surface of the salt box 500 is provided with a second engaging structure 540 engaged with the resin tank 400 , so as to engage the salt box 500 and the resin tank 400 .

[0456] In an optional embodiment, a second snap-fit ​​structure 540 is used to connect the salt tank 500 to the resin tank 400. This snap-fit ​​installation simplifies the installation and replacement process of the resin tank 400. This quick connection mechanism makes it easier for maintenance personnel to remove and replace the resin tank 400, reducing maintenance time and labor. Furthermore, the snap-fit ​​installation provides a secure connection, helping to ensure the stability of the resin tank 400 during operation and reducing potential problems caused by loose connections.

[0457] The second clamping structure 540 may be in the form of a hook type, a latch type, a magnetic type, a wedge lock type, a buckle type, a slot type or an elastic fastener, which is not specifically limited in this embodiment.

[0458] The number of second clamping structures 540 can be one or more. When multiple second clamping structures 540 are used, the safety and stability of the connection between the salt tank 500 and the resin tank 400 can be further improved. In an optional embodiment, a second clamping structure 540 is provided on both sides of the salt tank 500, and there are multiple second clamping structures 540. The multiple second clamping structures 540 are arranged along the height direction of the housing 10, further improving the firmness and stability of the connection between the salt tank 500 and the resin tank 400.

[0459] In addition, the snap-on design provides a secure connection between the resin tank 400 and the brine tank 500, ensuring that the two tanks will not accidentally separate during operation, thereby ensuring the stability and safety of the system. Furthermore, this snap-on design makes the water softener's components highly modular, allowing for easy addition, removal, or replacement of components as needed, enhancing the system's flexibility and scalability. Furthermore, a good snap-on design helps prevent brine or softened water from leaking at the connection, ensuring efficient operation of the system. For users, this snap-on design also simplifies the operating process, making maintenance and component replacement easy even for non-professionals, reducing the difficulty of use.

[0460] Furthermore, the above design allows the system to be expanded or reduced as needed. If processing capacity needs to be increased, additional resin tanks 400 can simply be added without requiring major modifications to the entire system. Furthermore, the side-by-side arrangement and snap-on mounting design potentially reduce manufacturing and maintenance costs. The simplified installation process reduces the time and materials required for installation and maintenance, thereby lowering overall costs.

[0461] In some embodiments, referring to Figures 50-52, at least one of the height and width of the salt box 500 and the resin tank 400 are equal.

[0462] In one optional embodiment, the salt box 500 and the resin tank 400 are of equal height. In another optional embodiment, the salt box 500 and the resin tank 400 are of equal width. In another optional embodiment, the salt box 500 and the resin tank 400 are of equal height and equal width. Such a design can make the two components better cooperate with each other to form a compact structure, thereby minimizing the overall size of the water softener.

[0463] By making the height and width of the salt box 500 and the resin tank 400 equal, they can be arranged more compactly inside the water softener housing 10 during installation. This compact arrangement can fully utilize the storage space of the water softener, avoid wasting space, and improve the space utilization rate of the water softener.

[0464] In some embodiments, the housing 10 includes a plurality of detachably mounted shell plates 13 , which enclose an accommodating space. At least one shell plate 13 is detachably connected to at least one of the resin tank 400 and the salt box 500 .

[0465] As will be appreciated, the housing 10 includes multiple panels 13 that are detachably connected to each other. The panels 13 are further subdivided into a front panel 11, a rear cover 12, an upper top panel 16, a lower bottom panel, and side panels 21, which together enclose a housing space. The detachable connection between the panels 13 facilitates maintenance and replacement of the water softener. To maintain or replace a component, the user simply removes the corresponding panel 13. This also makes the water softener more flexible and adaptable to different installation environments and usage requirements.

[0466] In one optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400, for example, the lower base plate and the side plates 21 on both sides are detachably connected to the resin tank 400. This facilitates user maintenance and replacement of the resin tank 400 and ensures that the housing 10 and the resin tank 400 do not accidentally separate during operation of the water softener, thereby ensuring system stability and safety. In another optional embodiment, at least one shell plate 13 is detachably connected to the salt tank 500, for example, the lower base plate and the front cover are detachably connected to the salt tank 500. This facilitates user maintenance and replacement of the salt tank 500 and ensures that the housing 10 and the salt tank 500 do not accidentally separate during operation of the water softener, thereby ensuring system stability and safety. In another optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400, and at least one shell plate 13 is detachably connected to the salt tank 500. The design can be based on actual application requirements and is not specifically limited in this embodiment.

[0467] In some embodiments, referring to Figures 50-52, a first clip structure A530 is provided on the outside of at least one of the salt box 500 and the resin tank 400, and at least one shell plate 13 is clipped and installed on the first clip structure A530 so that the shell plate 13 fits the outside of the salt box 500 or the resin tank 400.

[0468] It can be understood that in this embodiment, a first clamping structure A530 is provided on the salt box 500 or the resin tank 400. When the water softener is assembled, the salt box 500 and the resin tank 400 can be first clamped together by the second clamping structure A540, and then the shell plate 13 can be installed on the outside of the salt box 500 or the resin tank 400. The shell plate 13 can be directly installed on the outside of the salt box 500 or the resin tank 400 through the first clamping structure A530, so that the shell plate 13 is directly attached to the outside of the salt box 500 or the resin tank 400, making the connection between the shell plate 13 and the salt box 500 or the resin tank 400 tighter, thereby increasing the stability and firmness of the water softener. Moreover, since the shell plate 13 is directly attached to the outside of the salt box 500 or the resin tank 400, the volume of the water softener can be made lighter and thinner, thereby saving space and facilitating installation.

[0469] The number of first clamping structures A530 can be one or more. When multiple first clamping structures A530 are used, the safety and stability of the connection between the shell plate 13 and the salt tank 500 or the resin tank 400 can be further improved. In an optional embodiment, the first clamping structures A530 are provided on both sides of the salt tank 500 or the resin tank 400, and there are multiple first clamping structures A530. The multiple first clamping structures A530 are arranged along the height direction or the length direction of the shell 10, further improving the firmness and stability of the connection between the salt tank 500 and the resin tank 400.

[0470] In some embodiments, referring to Figures 50-52, at least one of the two adjacent shell plates 13 is provided with a buckle 14, and the other shell plate 13 is provided with a slot 15 matching the buckle 14.

[0471] It can be understood that in this embodiment, the two adjacent shell plates 13 can be connected by the clips 14 and the slots 15. The design of the clips 14 and the slots 15 can facilitate the installation and disassembly of the water softener shell plates 13, while ensuring the stability and tightness of the connection, and also making it easier for users to perform maintenance and cleaning.

[0472] It is understandable that there can be multiple buckles 14 and slots 15, and the buckles 14 and slots 15 are arranged in a one-to-one correspondence to ensure that the connection between the shell plates 13 is tighter and firmer, ensuring the stability and firmness of the water softener.

[0473] In some embodiments, referring to FIG. 16 and FIG. 18 , the water channel member 300 is disposed above the resin tank 400 .

[0474] In the related art, the water channel member 300 has a complex structure and is arranged in the width direction of the housing 10 relative to the resin tank 400, resulting in a larger water softener. To address this issue, the present embodiment places the water channel member 300 above the resin tank 400. Alternatively, the water channel member 300 can be arranged along the length of the housing 10, that is, the water channel member 300 and the resin tank 400 are stacked one above the other in the length direction. This ensures smooth water flow within the water softener, facilitates maintenance and operation, and reduces the width of the water softener, making the structure more compact and thus reducing the size of the water softener.

[0475] In some embodiments, referring to FIG. 16 to FIG. 18 , a plurality of flow channels 303 arranged in parallel are defined in the water channel member 300 , and each flow channel 303 is connected to a corresponding resin tank 400 , so that the plurality of resin tanks 400 are connected in parallel.

[0476] It will be appreciated that in this embodiment, each resin tank 400 has its own independent flow channel 303. After entering the water channel member 300, water flows through different flow channels 303 into each resin tank 400. After being processed within the resin tank 400, it flows out of the water softener for use by the user. This parallel arrangement allows multiple resin tanks 400 to operate simultaneously without interfering with each other. Each resin tank 400 acts as an independent processing unit, capable of performing its own softening treatment, thereby improving the overall processing efficiency and capacity of the water softener.

[0477] By arranging multiple resin tanks 400 in parallel and defining corresponding flow channels 303, the water softener can more flexibly respond to different water treatment requirements. At the same time, maintaining the independent operation of the resin tanks 400 can also prevent the normal operation of the entire system from being affected when a resin tank 400 fails.

[0478] In some embodiments, referring to FIG. 18 , the cross-sectional area of ​​the resin tank 400 is equal along the height direction of the resin tank 400 .

[0479] In an optional embodiment, the cross-section of the resin tank 400 is circular, and the diameter of the cross-section of the resin tank 400 is constant along the height direction of the resin tank 400. It is understood that by arranging the resin tank 400 with equal diameters along the axis, this embodiment can increase the proportion of the resin tank 400 to the surrounding area of ​​the storage space, thereby improving the arrangement ratio of the resin tank 400 in the storage space. At the same time, under the same resin capacity, the axial height of the resin tank 400 can be reduced, which is conducive to the miniaturization of the water softener design.

[0480] In some embodiments, referring to FIG. 16 to FIG. 18 , the resin tank 400 is detachably connected to the mounting port 302 ; or, the water channel member 300 and the resin tank 400 are integrally formed.

[0481] It is understood that in an optional embodiment, the resin tank 400 is provided with external threads and the mounting opening 302 is provided with internal threads, and the water channel member 300 can be securely connected to the resin tank 400 through a detachable connection between the resin tank 400 and the mounting opening 302. This connection method can provide better stability and reliability, ensuring that the water channel member 300 will not loosen or fall off during use.

[0482] In another optional embodiment, the water channel member 300 is integrally formed with the resin tank 400. It is understood that integrally forming a portion of the water channel member 300 with the resin tank 400 can reduce the number of assembly structures between the water channel member 300 and the resin tank 400, thereby reducing the space occupied by the assembly structure, further improving the utilization of the space, and facilitating a miniaturized design of the resin tank 400. Furthermore, the integral molding of the water channel member 300 and the resin tank 400 can simplify the assembly process, improve assembly efficiency, and enhance the sealing performance of the water channel member 300.

[0483] In some embodiments, referring to Figures 50-52, side panels 21 are extended on both sides of the resin tank 400. The side panels 21 are suitable for connecting with the housing 10. The side panels 21 define an installation cavity, and the water channel component 300 is disposed in the installation cavity.

[0484] As will be appreciated, in this embodiment, side panels 21 extend along the height of the housing 10 on either side of the resin tank 400. The connection between the side panels 21 and the housing 10 securely holds the resin tank 400 within the water softener, ensuring its stability. Furthermore, the mounting cavity defined by the side panels 21 provides a dedicated space for the water channel components 300, allowing for their orderly arrangement and installation.

[0485] Placing the water channel member 300 within the installation cavity makes the water softener's water system more centralized and compact, facilitating maintenance and operation. The design of the installation cavity also effectively isolates the water channel member 300 from other components, preventing interference. Therefore, the placement of the side panels 21 and the confinement of the installation cavity provide improved connectivity and support, creating an organized space for the installation of the water channel member 300. This design optimizes the water softener's structural layout, enhancing its stability and ease of use.

[0486] In some embodiments, referring to Figures 50-52, the water softener further includes a valve assembly 100 and an adapter assembly 200. The valve assembly 100 is disposed in the accommodating space. The adapter assembly 200 connects the valve assembly 100 and the water channel component 300 to control the flow direction of the water channel in the resin tank 400, wherein the adapter assembly 200 and the water channel component 300 are detachably connected. The valve assembly 100 can control the inflow and outflow of water by means of a switch, thereby achieving control over the water channel in the resin tank 400. The adapter assembly 200 is used to connect the valve assembly 100 and the water channel component 300. It can be detachably connected to the water channel component 300 by means of threads, quick connectors, or other connection methods. This design makes the maintenance of the water softener more convenient. When the water channel component 300 needs to be replaced or cleaned, it can be easily disassembled from the adapter assembly 200.

[0487] Through the design of the valve assembly 100 and the adapter assembly 200, the water softener can control the flow direction of the water channel in the resin tank 400 and facilitate the replacement and maintenance of the water channel component 300. This design improves the functionality and maintainability of the water softener, making it more suitable for different water treatment needs.

[0488] In the related art, a conventional water channel component 300 is integrated with various channels for communicating with the resin tank 400, and is also integrated with devices and passages for controlling salt absorption. In order to facilitate the arrangement of various passages and devices, the overall structure is relatively large, especially in the width direction of the entire water channel component 300. It has a large dimensional extension, which makes the entire water channel component 300 complex in structure, difficult to manufacture, and occupies a large space. In particular, the water channel component 300 requires more space in the width direction to realize its own layout.

[0489] In some embodiments, referring to Figures 50-52, the water softener includes a shell 10, a resin tank 400, a water path component 300, a valve assembly 100 and an adapter assembly 200. The shell 10 is formed with an accommodating space, the resin tank 400 is arranged in the accommodating space, the water path component 300 is arranged in the accommodating space and is located above the resin tank 400, the water path component 300 is connected to the resin tank 400, and the valve assembly 100 is connected to the water path component 300 through the adapter assembly 200 to control the flow direction of the water path in the resin tank 400.

[0490] It can be understood that in this embodiment, by independently arranging the valve assembly 100, the adapter assembly 200 and the water channel component 300, the overall structure of the water channel part is simplified, and the difficulty of preparing the water channel component 300 is reduced. The water channel component 300 is arranged above the resin tank 400, and the resin tank 400 can be stacked and arranged in the vertical direction, reducing the area occupied by the bottom of the water softener. The separate connection of each component is beneficial to the overall layout, thereby simplifying the overall structure, improving the space utilization of the water softening device, and realizing the miniaturized design of the water softening device, which is convenient for the water softening device to be installed in narrow spaces with size restrictions such as cabinets, balconies, and bathroom cabinets, thereby improving the applicability of the water softening device.

[0491] During the switching process of each water channel, there are two main states: one is the soft water channel state for softening water quality, and the other is the regeneration water channel state for regenerating resin particles. In the soft water channel state, the water channel is input from the resin filling area at the top of the resin tank 400, then rises through the central tube 410 and is output. In the regeneration water channel state, the water channel is input from the central tube 410, then rises through the resin particle filling area and is output. In other words, the flow direction of the regeneration water channel and the flow direction of the soft water water channel need to be opposite. In this embodiment, the connection with the resin tank 400 is achieved through the water channel component 300, and the flow direction of the water channel is controlled by the adapter assembly 200 connected thereto, thereby realizing the formation of the two main water channels. By separately arranging the adapter assembly 200 and the water channel component 300, the overall layout is facilitated, and the overall preparation difficulty and manufacturing cost are reduced.

[0492] In this embodiment, the valve assembly 100 can be a conventional multi-way control valve body, which generally has five functional positions: water supply, backwash, regeneration, water replenishment, and forward wash. The three functional waterways for water supply, water replenishment, and forward wash have forward flow, i.e., the flow direction of the waterways in the resin tank 400 is the same as the soft water waterway in this embodiment. The two functional waterways for backwash and regeneration have reverse flow, i.e., the flow direction of the waterways in the resin tank 400 is the same as the regeneration waterway in this embodiment. The multi-way valve body switches between the various waterways via the valve core 140 therein. In this embodiment, the multi-way control valve body is connected to the adapter assembly 200 so that the adapter assembly 200 can control the flow direction of the waterways.

[0493] It can be understood that, as shown in reference figure 18, the resin tank 400 in each embodiment of the present application can adopt a conventional resin tank structure, that is, it has a barrel structure for filling resin particles, and also has an independent central tube 410 in the barrel body. The resin filling part 420 is located in the outer part of the central tube 410, and the water channel realizes softening and other functions by contacting the resin particles in the resin tank 400.

[0494] In some embodiments, referring to Figures 50-52, the adapter assembly 200 and the valve assembly 100 are arranged side by side above the water channel component 300 along the length direction of the shell 10, and the valve assembly 100 is connected to the external water channel through the rear cover plate 12 of the shell 10.

[0495] It will be appreciated that in this embodiment, arranging the adapter assembly 200 and the valve assembly 100 side by side along the length of the housing 10 above the water channel member 300 can reduce the space occupied in the width direction, making the water softener more compact and effectively reducing the size of the water softener. This design allows the various components of the water softener to be arranged more closely together, thus saving space and making the water softener more suitable for installation in space-constrained environments such as homes and offices.

[0496] In this embodiment, the valve assembly 100 is connected to the external water circuit via the rear cover 12 of the housing 10. This means that the water softener's water inlet and outlet are located on the rear cover 12 of the housing 10, minimizing the space occupied by the water softener. This is particularly important for installations in limited spaces, such as kitchens and bathrooms. By placing the water inlet and outlet on the rear, space is effectively saved, making it easier to integrate the water softener into existing layouts without requiring long pipes for water connections.

[0497] In some embodiments, referring to Figures 50-52, the water softener also includes a control box 30, which is connected to the valve assembly 100, and the control box 30, the adapter assembly 200 and the valve assembly 100 are arranged side by side above the water channel component 300 along the length direction of the shell 10.

[0498] It will be appreciated that in this embodiment, the water softener typically also includes a control box 30, which is used to control the operation and operation of the water softener. The control box 30 is typically connected to the valve assembly 100, controlling the opening and closing of the valve assembly 100 via control signals, thereby adjusting the operating state of the water softener. To achieve a more compact overall structure of the water softener, the control box 30, adapter assembly 200, and valve assembly 100 are arranged side by side along the length of the housing 10, above the water channel member 300. This design maximizes the space within the housing 10, tightly integrating the various components, reducing the widthwise occupied space, and further reducing the size of the water softener.

[0499] Through this layout, the key components of the water softener can be closely matched in a limited space, improving the overall performance and reliability of the water softener. At the same time, this design also facilitates the maintenance and repair of the water softener, making it easier for users to operate and maintain it.

[0500] In some embodiments, referring to Figures 50-52, the housing 10 includes a detachable top plate 16, which is disposed above the control box 30, the adapter assembly 200 and the valve assembly 100.

[0501] It is understood that in this embodiment, the housing 10 includes a detachable top plate 16, which is installed above the control box 30, the adapter assembly 200, and the valve assembly 100 to protect these key components. The design of the top plate 16 effectively prevents dust, debris, and other foreign matter from entering the interior of the water softener during normal operation, keeping the equipment clean and operating normally. At the same time, the detachable design of the top plate 16 also facilitates the repair and maintenance of the water softener. When the control box 30, the adapter assembly 200, or the valve assembly 100 needs to be repaired, replaced, or adjusted, the user only needs to simply open the top plate 16 to easily operate the interior of the water softener. This design makes the repair process more efficient and convenient.

[0502] Furthermore, placing the top plate 16 directly over the control box 30, adapter assembly 200, and valve assembly 100 also helps reduce the space occupied by the water softener. The compact design of the top plate 16 makes the overall structure of the water softener more compact, occupies less space, and makes it easier to integrate the water softener into various environments.

[0503] In some embodiments, referring to Figures 50-52, the water softener also includes a salt box 500, which is arranged on a side of the accommodating space close to the front panel 11 of the shell 10. The salt box 500 is connected to the adapter assembly 200 through the salt absorption pipe A550. The salt box 500 is injected with water and absorbs salt through the regulation of the valve assembly 100, and the adapter assembly 200 is arranged on a side of the valve assembly 100 close to the salt box 500.

[0504] It will be appreciated that, in this embodiment, for ease of use and maintenance, the salt tank 500 is typically positioned on the side of the housing 10 near the front panel 11. This placement of the salt tank 500 allows the user to more conveniently add or replace salt, while also facilitating cleaning and maintenance. The salt tank 500 is connected to the adapter assembly 200 via a salt intake pipe A550. The salt intake pipe A550 transports salt from the salt tank 500 to the adapter assembly 200 for use in the water softener for salt solution preparation and regeneration. The adapter assembly 200 is typically positioned on the side of the valve assembly 100 near the salt tank 500, reducing the length of the salt intake pipe A550 and making the water softener more compact. This design reduces resistance and pressure loss in the salt intake pipe A550, improving salt solution delivery efficiency while also reducing the size of the water softener.

[0505] In some embodiments, referring to Figures 50-52, the water softener also includes an overflow pipe 40, the rear cover plate 12 of the shell 10 is provided with a through-plate joint 103, the overflow pipe 40 is installed on the outer wall of the resin tank 400, one end of the overflow pipe 40 is connected to the salt box 500, and the other end is suitable for communicating with the outside through the through-plate joint 103.

[0506] It is understandable that, in this embodiment, an overflow port can be provided on the back side of the salt box 500, and the overflow port is connected to the outside through the overflow pipe 40. When the water level in the salt box 500 is too high, the excess water can be discharged through the overflow pipe 40, thereby preventing water from overflowing directly from the top of the salt box 500 and causing moisture and pollution inside the equipment or the surrounding environment.

[0507] The overflow pipe 40 can be installed on the outer wall of the resin tank 400, that is, by installing the overflow pipe 40 along the length direction of the shell 10, the first end of the overflow pipe 40 is connected to the overflow port of the salt box 500. Such a design can guide the water that may overflow to a safe drainage position through the pipe, thereby ensuring the stability of the liquid level in the salt box 500; by providing a through-plate joint 103 on the rear cover plate 12 of the water softener, it is connected to the second end of the overflow pipe 40, which is used to guide the overflow water to the sewer or other suitable location for discharge, thereby ensuring the sealing and effectiveness of the entire anti-overflow structure; in addition, by arranging the overflow pipe 40 horizontally from front to back, the thickness of the water softener is reduced, which is more conducive to miniaturized design and can adapt to various narrow installation spaces, thereby improving the user's installation flexibility and usage experience.

[0508] In some embodiments, referring to FIG. 50 to FIG. 52 , a support member 17 is disposed in the housing 10 . The support member 17 connects the resin tank 400 and the salt box 500 , and the support member 17 is disposed above the salt box 500 .

[0509] It will be appreciated that in this embodiment, a support member 17 is provided within the housing 10. The support member 17 is primarily used to secure and support the resin tank 400 and the salt tank 500 within the water softener. This prevents the water softener from shaking or shifting during operation, thereby ensuring the normal operation and service life of the water softener.

[0510] Support member 17 connects the resin tank 400 and the brine tank 500 and is positioned above the brine tank 500. This design optimizes the spacing between the various components and pipes within the water softener, preventing interference and friction. Furthermore, the position of support member 17 makes the water softener more compact and stable, reducing noise and vibration during operation.

[0511] Furthermore, the support member 17 may be provided with a snap-fit ​​structure for snapping onto the shell plate 13, thereby forming a unitary structure of the water softener and enhancing its overall performance and stability. The support member 17 may also be provided with a mounting portion for mounting and securing the control box 30 to prevent it from loosening or shaking.

[0512] In some embodiments, referring to Figures 50-52, the shell 10 includes a plurality of detachably installed shell plates 13, which are arranged to form an accommodating space, and at least one shell plate 13 is detachably connected to at least one of the resin tank 400, the water channel component 300, the valve assembly 100 and the adapter assembly 200.

[0513] It will be appreciated that, in this embodiment, the housing 10 includes multiple shell panels 13, which are detachably connected to each other. The multiple shell panels 13 can be further subdivided into a front panel 11, a rear cover 12, an upper top panel 16, a lower bottom panel, and side panels, which together enclose a storage space. The detachable connection between the multiple shell panels 13 facilitates maintenance and replacement of the water softener. When maintenance or replacement of water softener components is required, the user only needs to remove the corresponding shell panel 13. This also makes the water softener more flexible and adaptable to different installation environments and usage requirements.

[0514] In one optional embodiment, at least one shell plate 13 is detachably connected to the resin tank 400. For example, the lower base plate and the side plates 21 on either side are detachably connected to the resin tank 400. This facilitates user maintenance and replacement of the resin tank 400 and prevents accidental separation of the housing 10 and the resin tank 400 during operation of the water softener, thereby ensuring system stability and safety. In another optional embodiment, at least one shell plate 13 is detachably connected to the valve assembly 100, facilitating installation and securing of the valve assembly 100, as well as ease of disassembly and maintenance.

[0515] In other embodiments, at least one shell plate 13 is detachably connected to the salt box 500, for example, the lower base plate and the front cover plate are detachably connected to the salt box 500, so as to facilitate the user to maintain and replace the salt box 500, and ensure that the shell 10 and the salt box 500 will not be accidentally separated during the operation of the water softener, thereby ensuring the stability and safety of the system.

[0516] In some embodiments, referring to Figures 50-52, side panels 21 are extended on both sides of the resin tank 400 or the water channel component 300. The side panels 21 are suitable for connecting with the shell 10. The side panels 21 define an installation cavity, and the valve assembly 100 and the adapter assembly 200 are both arranged in the installation cavity.

[0517] In an optional embodiment, side panels 21 extend along the height of the housing 10 on either side of the resin tank 400. The connection between the side panels 21 and the housing 10 secures the resin tank 400 within the water softener, ensuring its stability. Furthermore, the mounting cavity defined by the side panels 21 provides a dedicated space for the waterway component 300, valve assembly 100, and adapter assembly 200, allowing for their orderly arrangement and installation.

[0518] In an alternative embodiment, side panels 21 extend along the height of the housing 10 on either side of the water channel member 300. The connection between the side panels 21 and the housing 10 securely holds the water channel member 300 and the resin tank 400 within the water softener, ensuring their stability. Furthermore, the mounting cavity defined by the side panels 21 provides a dedicated space for the valve assembly 100 and adapter assembly 200, allowing for their orderly arrangement and installation.

[0519] Placing the water channel member 300 within the installation cavity makes the water softener's water system more centralized and compact, facilitating maintenance and operation. The design of the installation cavity also effectively isolates the water channel member 300 from other components, preventing interference. Therefore, the placement of the side panels 21 and the confinement of the installation cavity provide improved connectivity and support, creating an organized space for the installation of the water channel member 300. This design optimizes the water softener's structural layout, enhancing its stability and ease of use.

[0520] In some embodiments, referring to Figures 16, 18 and 43, the water softener includes multiple resin tanks 400 arranged side by side, the number of the installation ports 302 is multiple, and the multiple resin tanks 400 are arranged side by side in the accommodating space along the length direction of the housing 10.

[0521] It is understandable that in this embodiment, the resin tank 400, as one of the core components of the water softener, is placed inside the water softener. The resin tank 400 includes a plurality of resin tanks 400, and the plurality of resin tanks 400 are arranged side by side on the back side of the salt tank 500 along the length of the water softener. This parallel layout can make full use of the internal space of the water softener and avoid the increase in overall thickness caused by the stacking of components. By arranging the resin tank 400 and the salt tank 500 side by side, rather than vertically or cross-stacked, the thickness of the entire water softener is effectively reduced while maintaining functional integrity, meeting the requirements of ultra-thin design, and is particularly suitable for environments with limited installation space. In addition, the resin tank 400 and the salt tank 500 are compactly arranged side by side, reducing the complexity and length of the internal pipe connection, which not only helps to improve the water exchange efficiency, but also reduces the equipment manufacturing cost and potential failure rate, further improving the product's user experience and durability.

[0522] In particular, if multiple resin tanks 400 are used in parallel, when one resin tank 400 reaches saturation, the remaining unsaturated resin tanks 400 can continue ion exchange, ensuring the softener can continuously provide softened water and improving system stability and reliability. Furthermore, by adjusting the operating order of the resin tanks 400 or configuring resin tanks 400 of different capacities, the water flow rate and softening effect can be flexibly adjusted according to actual needs, achieving precise control of the water softening process.

[0523] Therefore, this embodiment, through the reasonable design of the number and layout of the resin tanks 400, not only achieves the ultra-thin transformation of the water softener, but also improves its functionality, ease of use and work efficiency, and significantly improves the user experience.

[0524] In an optional embodiment, there are multiple installation openings 302, which are spaced apart along the length of the water channel member 300. To avoid complicating the flow channel 303 structure, the flow channel 303 is typically connected as a single resin tank 400. When each resin tank 400 holds the same number of resin particles, it often requires a larger opening. However, a larger opening will affect the contact between the raw water and the resin, and also cause the entire system to occupy a larger space in the width direction. In this embodiment, due to the separate arrangement of the water channel component 300 and the adapter assembly 200, the structure of the water channel component 300 is simple, and an installation port 302 is constructed on the water channel component 300, and the installation port 302 can be connected to the resin tank 400, so that multiple installation ports 302 can be arranged in the length direction of the water channel component 300 for installing the resin tank 400. The installation of multiple resin tanks 400 makes it possible to achieve the same number of resin particles when required through the distribution of multiple resin tanks 400, which makes the volume of a single resin tank 400 smaller, and thus makes the overall space occupied by the water channel component 300 in the width direction small.

[0525] Specifically, the water channel member 300 has a first water channel and a second water channel. The first water channel is connected to the resin filling portion 420 of each resin tank 400, and the second water channel is connected to the central tube 410 of each resin tank 400. This allows the working fluid to enter the resin filling portion 420 of each resin tank 400 through the first water channel. Similarly, the working fluid can also enter the central tube 410 of each resin tank 400 through the second water channel.

[0526] In specific applications, in some embodiments, the number of mounting openings 302 on the water channel member 300 is two, and the two mounting openings 302 are spaced apart along the extension direction of the water channel member 300. Of course, in other embodiments, the number of water channel members 300 can also be three, four, etc. The embodiments of this application and the accompanying drawings are described using an example in which there are two mounting openings 302.

[0527] In some embodiments, referring to Figures 16-18, the water channel component 300 is constructed with a first connection end 330 and a second connection end 340 that are connected to the installation port 302, and the adapter assembly 200 is connected to the water channel component 300 through the first connection end 330 and the second connection end 340, and the first connection end 330 and the second connection end 340 are located on the same one of the multiple installation ports 302.

[0528] The water channel member 300 includes a first connection end 330 and a second connection end 340 that communicate with the installation port 302. The adapter assembly 200 is connected to the water channel member 300 via the first connection end 330 and the second connection end 340. The first connection end 330 can realize the input and output of the working fluid, and the second connection end 340 can also realize the input and output of the working fluid. The adapter assembly 200 switches the water channel flow direction by controlling whether the input working fluid enters through the first connection end 330 or the second connection end 340. The connection between the connection port and the water channel member 300 facilitates installation and subsequent maintenance and replacement, thereby reducing user costs.

[0529] It is understood that in this embodiment, the valve assembly 100 is connected to the external water circuit via the water inlet pipe 112 and the water outlet pipe 113. That is, the water inlet and water outlet of the water softener are arranged on the rear cover plate 12 of the housing 10. At the same time, the valve assembly 100 can also be arranged on the side close to the rear cover plate 12 to reduce the length of the water inlet pipe 112 and the water outlet pipe 113, facilitate the arrangement of the water inlet pipe 112 and the water outlet pipe 113, and minimize the space occupied by the water softener. This is particularly important for installation in environments with limited space, such as kitchens and bathrooms. By arranging the water inlet and water outlet on the back, space can be effectively saved, making it easier for the water softener to be embedded in the existing layout, without having to set up long pipes to achieve water connection.

[0530] In the related art, the control of the water softener valve assembly 100 and the passage control of the adapter assembly 200 require separate electrical control components for control, resulting in a complex structure and large size of the entire control system, which also increases the failure rate, maintenance difficulty and repair cost.

[0531] In some embodiments, the valve assembly 100 includes a valve body 110, a valve core 140, a transmission mechanism 141 and a driving part 142. The valve core 140 is connected to the driving part 142 through the transmission mechanism 141. The adapter assembly 200 is provided with a sewage path 2107 and a pressure rod. The driving part 142 is suitable for driving the valve core 140 to rotate relative to the valve body 110 through the transmission mechanism 141 to realize the switching of different water paths, and the transmission mechanism 141 is suitable for driving the pressure rod to switch between the sewage position and the non-sewage position. In the non-sewage position, the pressure rod blocks the sewage path 2107. In the sewage position, the pressure rod is moved away to open the sewage path 2107.

[0532] It can be understood that in this embodiment, the valve body 110 is formed with a valve cavity 111, a water inlet channel 163, a water outlet channel, a salt absorption channel and a backwash channel. The valve core 140 is rotatably arranged in the valve cavity 111, and the driving part 142 is connected to the valve core 140 through a rotating mechanism. When the driving part 142 rotates, it drives the valve core 140 to rotate, so as to realize the connection between the valve cavity 111 and different water channels, and realize the switching of different working states of the water softener. At the same time, the transmission mechanism 141 can also drive the pressure rod to switch between the sewage discharge position and the non-sewage discharge position during the movement, so as to realize the opening and closing of the sewage discharge channel 2107. That is, when only one driving part 142 is provided, the switching of different water channels of the valve assembly 100 and the control of the opening and closing of the sewage discharge channel 2107 can be realized at the same time, which simplifies the control logic, improves the control efficiency, reduces the number of control components, reduces the volume and occupied space of the water softener, and also reduces the failure rate of the water control component.

[0533] In some embodiments, referring to Figures 1-5, the transmission mechanism 141 includes: a driving gear 1432, which is arranged at the output end of the driving part 142; a driven gear 1431, which is engaged with the driving gear 1432, and the driven gear 1431 has at least one driving block 1433. During the rotation of the transmission mechanism 141, the driving block 1433 is suitable for abutting and pushing the pressure rod to switch between the sewage discharge position and the non-sewage discharge position; a rotating shaft 150, which is connected to the driven gear 1431; wherein the rotating shaft 150 is connected to the valve core 140 to drive the valve core 140 to control the water path switching.

[0534] Referring to Figures 53 to 57, a water softener is provided, including a resin tank B200, a salt box B300 and a shell B100, wherein the salt box B300 is arranged on the front side of the resin tank B200; the shell B100 is arranged on the outside of the resin tank B200 and the salt box B300, and the shell B100 includes a top cover B110, a base B130 and several side panels B120, the top cover B110 and the base B130 are connected through the side panels B120, at least one side panel B120 is inserted between the top cover B110 and the base B130, and the side panel B120 is covered on the side of the resin tank B200 and the salt box B300, and at least one of the resin tank B200 and the salt box B300 is in contact with and fixedly connected to the side panel B120.

[0535] Resin tank B200 is filled with resin material, which softens raw water entering it and produces soft water. Users can then obtain the softened water from a water softener. The resin material removes calcium and magnesium ions from the raw water, making the soft water less hard than the raw water. Salt tank B300 is used to store salt. By introducing water (either raw water or softened water) into salt tank B300, the solid salt in tank B300 dissolves into a salt solution, which is then transported to resin tank B200. The calcium and magnesium ions in the resin material dissolve in the salt solution and flow out of tank B200 along with the salt solution. The resin material in tank B200 can be cleaned to allow it to continue softening raw water. A salt inlet B330 is located on the front of salt tank B300 for replenishing salt.

[0536] As shown in Figures 53 to 56 , the housing B100 is disposed outside the resin tank B200 and the salt tank B300, and the salt tank B300 is disposed in front of the resin tank B200. That is, the salt tank B300 and the resin tank B200 are arranged side by side in a front-to-back arrangement. Compared to the arrangement in which the salt tank B300 is nested outside the resin tank B200, the front-to-back arrangement of the salt tank B300 and the resin tank B200 can reduce the length of the resin tank B200 and the salt tank B300 in the left-right direction and the height of the salt tank B300. When the front-to-back direction is the length direction of the water softener and the left-to-right direction is the width direction of the water softener, the front-to-back arrangement of the salt tank B300 and the resin tank B200 can reduce the width and height of the water softener, thereby resolving the problem of the water softener being too wide and achieving a thinner water softener. The water softener of the present embodiment can be installed in a small space.

[0537] As shown in FIG54 , the housing B100 includes a top cover B110, a base B130, and several side panels B120. The top cover B110 and the base B130 are connected by the side panels B120. At least one side panel B120 is inserted between the top cover B110 and the base B130. The side panels B120 are fixed between the top cover B110 and the base B130 by insertion. The installation method of the side panels B120 is simple. The base B130 sets the lower limit for the side panels B120, and the top cover B110 sets the upper limit for the side panels B120.

[0538] The side panel B120 is covered on the side of the resin tank B200 and the salt box B300. At least one of the resin tank B200 and the salt box B300 is in contact with and fixedly connected to the side panel B120. At least one of the resin tank B200 and the salt box B300 is in contact with the side panel B120 and can be positioned with each other. It can also reduce the installation gap between at least one of the resin tank B200 and the salt box B300 and the side panel B120. At least one of the resin tank B200 and the salt box B300 is also fixedly connected to the side panel B120, that is, the side panel B120 is directly connected to the side of at least one of the resin tank B200 and the salt box B300, and the installation stability of the side panel B120 is better. "At least one of the resin tank B200 and the salt box B300 is in contact with the side panel B120" can be understood as at least a part of the resin tank B200 is in contact with the side panel B120, and / or at least a part of the salt box B300 is in contact with the side panel B120. When the side panel B120 is on the left and / or right side of the resin tank B200 and the salt box B300, the left side (and / or right side) of the resin tank B200 and the salt box B300 should be set to be coplanar as much as possible, and the contact area between the resin tank B200 and the salt box B300 and the side panel B120 should be increased as much as possible to ensure the volume of the resin tank B200 and the salt box B300, and to ensure that the side panel B120 fully contacts the resin tank B200 and the salt box B300, thereby reducing the installation gap and making full use of the space inside the shell B100.

[0539] At least one of the resin tank B200 and the salt box B300 is in contact with and directly fixedly connected to the side panel B120, including the side panel B120 being in contact with and directly fixedly connected to the resin tank B200, the side panel B120 being in contact with and directly fixedly connected to the salt box B300, and the side panel B120 being in contact with and fixedly connected to the resin tank B200 and the salt box B300 at the same time.

[0540] Taking the example of a direct, fixed connection between the side panel B120 and the resin tank B200, the installation precision of the side panel B120 and the resin tank B200 is high, the installation gap between the side panel B120 and the resin tank B200 is small, and the installation of the side panel B120 and the resin tank B200 is more compact, which helps to reduce the left-right and front-back dimensions of the water softener, as well as the volume of the water softener. Furthermore, the side panel B120 is inserted and fixed between the top cover B110 and the base B130, which simplifies the installation method and helps improve installation efficiency. Similarly, the installation of the side panel B120 and the salt tank B300 is the same as the technical effect described above and will not be repeated here. When the side panel B120 abuts against and fixes the resin tank B200 and the salt box B300 at the same time, the side surfaces of the resin tank B200 and the salt box B300 in the left and right directions can be set to be coplanar to reduce the size of the water softener in the left and right directions, that is, to reduce the width of the water softener. In addition, the side panel B120 is doubly fixed by the resin tank B200 and the salt box B300, and the fixing effect is better. The side panel B120 can be quickly and accurately fixed to the sides of the resin tank B200 and the salt box B300. The installation efficiency of the side panel B120 is high and the connection stability is good.

[0541] In the water softener of the present embodiment, the side panel B120 is secured to the base B130 via the top cover B110 of the housing B100. This is then fixedly connected to the side panel B120 by at least one of the resin tank B200 and the salt tank B300. This allows for multiple fixations of the side panel B120, resulting in a stable and simple structure. At least one of the resin tank B200 and the salt tank B300 is in contact with the side panel B120, which reduces the installation gap between at least one of the resin tank B200 and the salt tank B300 and the side panel B120. This fully utilizes the space within the housing B100, reduces the left-right and front-back dimensions of the water softener, and makes the water softener thinner, thereby reducing the size of the water softener and achieving a compact size.

[0542] The top cover B110 may be directly connected to the top of at least one of the resin tank B200 and the brine tank B300, and / or the base B130 may be directly connected to the bottom of at least one of the resin tank B200 and the brine tank B300. The water softener of the present embodiment is not limited to the structure of the top cover B110 and the base B130 of the housing B100 and may be modified as needed.

[0543] It should be noted that the side panel B120 can be understood as the shell B100 structure between the top cover B110 and the base B130. The side panel B120 can be set on at least one of the front, rear, left and right sides, and the structural form of the side panel B120 is diverse. Regarding the structural form of the side panel B120: First, multiple side panels B120 are arranged between the top cover B110 and the base B130. As shown in Figure 56, the side panel B120 includes a detachably connected front side panel B123, a left side panel B121, a right side panel B122 and a rear side panel B124. The left side panel B121, the right side panel B122 and the rear side panel B124 are all plugged into the top cover B110 and the base B130. The front side panel B123 can be fixedly connected to the salt box B300, and the left side panel B121 and the right side panel B122 have the same or similar structures; second, an integral side panel B120 (not shown in the figure) can be arranged between the top cover B110 and the base B130. The side panels B120 are arranged to form a closed loop structure, and the side panels B120 are covered in the front, back, left and right directions of the resin tank B200 and the salt box B300. In the following embodiments, the structural form of the side panel B120 is not limited. Referring to Figure 54, a plurality of side panels B120 are arranged between the top cover B110 and the base B130 as an example. The front side panel B123 is directly connected to the salt box B300 and is not directly connected to the resin tank B200.
