Description

Technical Field

[0001] The present invention relates to the technical field of water treatment equipment, and particularly to a water softener. Background Art

[0002] A water softener is one of the devices used to achieve water treatment. Its main working principle is as follows: The water softener allows water to flow through resin particles. The resin particles adsorb the hardness ions in the water and release an equal amount of sodium ions. As time goes by, the resin particles gradually become saturated and need to be regenerated. During the regeneration process, brine passes through the resin particles to wash away the adsorbed hardness ions and restore the resin to a state where it can be used continuously.

[0003] In the related art, the control system of the water softener valve requires multiple electrical control components for control. The entire control system has a complex structure, which increases the failure rate, the maintenance difficulty, and the repair cost. Summary of the Invention

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0131] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationships indicated by the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the embodiments of the present application. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0132] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0133] In the embodiments of the present application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "below" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0134] In the description of this specification, the descriptions with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms are not necessarily directed to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0135] Hard water can have various effects on daily life and household appliances. For example, it can reduce the washing effect, accumulate inside the water pipes, causing a decrease in water flow, resulting in damage to the performance and lifespan of the appliances, and can cause skin problems, etc. Therefore, people will use water softening equipment to treat tap water in daily life. Using water softening equipment can effectively remove the minerals in hard water, improve water quality, and enhance the quality of life. Generally, the treatment principle of water softening equipment is to remove calcium and magnesium ions in water through the process of ion exchange, thereby converting hard water into soft water.

[0136] Among them, the method of using resin for treatment is one of the common methods. This resin is a polymer substance with a special structure and has a positive charge on its surface. When hard water passes through the resin particles, calcium and magnesium ions in it will adsorb with the positive charge on the resin surface and replace the original sodium ions on the resin. After a period of time, the resin particles gradually become saturated. At this time, it is necessary to inhale brine to clean the resin particles, and the resin particles are regenerated by replacing the adsorbed ions.

[0137] In the related art, the switching of the water circuit is realized by means of a control valve to achieve the various functions of the water softener, and the sewage discharged after cleaning the resin particles is discharged through a separate sewage discharge channel. That is, in the related art, the switching of the water circuit and the opening of the sewage discharge channel are controlled separately, which improves the complexity of the control system, increases the number of components of the equipment, raises the preparation cost, and the complex control system reduces the reliability of the overall equipment.

[0138] Regarding the problems in the related art, see Figures 1-3As shown in the figure, the present invention provides a water softener, which includes a water softening valve 100, a transfer assembly 200, a water circuit assembly 300, and a resin tank 400. The water softening valve 100 includes a valve body 110, a valve core assembly 140, a driving part 142, and a transmission mechanism 141. The valve core assembly 140 and the driving part 142 are both arranged inside the valve body 110. The driving part 142 is in transmission connection with the valve core through the transmission mechanism 141, so that the valve core assembly 140 controls the water circuit switching under the drive of the driving part 142. The transfer assembly 200 is connected to the water softening valve 100 and is located on one side of the water softening valve 100. The transfer assembly 200 has a sewage discharge water circuit 2107, and the transfer assembly 200 cooperates with the transmission mechanism 141. The driving part 142 is adapted to drive the transmission mechanism 141 to act to control the opening of the sewage discharge water circuit 2107. The water circuit assembly 300 is connected to the transfer assembly 200, and the water circuit assembly 300 is used to guide the flow of the water circuit. The resin tank 400 is fixedly connected to the water circuit assembly 300, and the resin tank 400 is used to soften the flowing water. When the water softener is operating and different functions are required, the water flow direction in the resin tank 400 is different. It is specified that the water flow direction in which the water enters the resin filling area at the top of the resin tank 400 and then rises through the central pipe 410 and is output is the forward circulation water circuit. It is specified that the water flow direction in which the water enters through the central pipe 410 and then rises through the resin particle filling area and is output is the reverse circulation water circuit. In the water softener, the reverse circulation water circuit is usually output through the sewage discharge water circuit 2107, and the sewage discharge water circuit 2107 is in a closed state under normal conditions and is opened when sewage discharge is required. In this embodiment, through the cooperation of the driving part 142 and the transmission mechanism 141, on the one hand, it can control the switching of each water circuit, and on the other hand, while controlling the switching of each water circuit, it can cooperate with the transfer assembly 200 to realize the opening of the sewage discharge water circuit 2107, thereby realizing the opening of each water circuit in the water softener and realizing each function of the water softener, simplifying the control system of the water softener and improving the stability of the control system.

[0139] When specifically set, as Figure 5 shown, the transmission mechanism 141 is in transmission connection with the driving part 142. The driving part 142 can drive the transmission mechanism 141 to rotate. The rotation of the transmission mechanism 141 can drive the valve core assembly 140 to rotate. When the valve core assembly 140 rotates to different positions, different water circuit switching can be realized, thereby realizing different functions of the water softener. For example, the transmission mechanism 141 has corresponding matching parts. When the transmission mechanism 141 rotates or moves to a set position, the matching parts cooperate with the corresponding parts on the transfer assembly 200, thereby realizing the opening of the sewage discharge water circuit 2107. While different functions of the water softener are realized, the transmission mechanism 141 can cooperate with the transfer assembly 200 to realize the opening of the sewage discharge water circuit 2107, thereby realizing the realization of different functional positions of the water softener controlled by one driving part 142.

[0140] It is understandable that in order to realize the control of the sewage discharge path 2107 in the related technology, 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 discharge path 2107. The number of control components is large and the entire control system is complex. In this example, the action of the valve core assembly 140 can be controlled by the transmission component first, thereby realizing the switching of each waterway, and in the switching process of each waterway, the transmission mechanism 141 can cooperate with the adapter assembly 200, and the sewage discharge path 2107 can be opened by cooperating with the adapter assembly 200. That is, the waterway switching and the control of the sewage discharge 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.

[0141] In specific applications, raw water is connected through the soft water valve 100, and then enters the resin tank 400 through the adapter assembly 200. The resin tank 400 is filled with resin particles and a central tube 410. The raw water is processed by the resin particles in the resin tank 400 and then output by the soft water valve 100 through the adapter assembly 200. The flow direction of the waterway in the resin tank 400 is controlled by the adapter assembly 200. That is, the flow direction of the waterway in the resin tank 400 is controlled by the transmission mechanism 141 in cooperation with the adapter assembly 200, thereby controlling the forward circulation waterway and the reverse circulation waterway in the resin tank 400.

[0142] like Figure 6 , Figure 7 As shown, according to an embodiment provided by the present invention, a valve cavity 111 is provided in the valve body 110 of the water softener 100, and a water inlet pipe 112, a water outlet pipe 113, a tank inlet pipe 114 and a tank outlet pipe 115 are also provided on the valve body 110, which are all connected to the valve cavity 111, and a valve seat 116 is provided in the valve cavity 111; a valve core assembly 140 is provided on the valve seat 116 and is located in the valve cavity 111, and the valve core assembly 140 switches between a service position, a salt absorption position, a bypass position, a backwash position and a water replenishment position relative to the valve seat 116, so that the valve core assembly 140 and the valve seat 116 define a service waterway, a salt absorption waterway, a bypass waterway, a backwash waterway and a water replenishment waterway. In this embodiment, when the water softener is in operation, there are mainly a service position, a salt absorption position, a bypass position, a backwash position and a water replenishment position, and each position corresponds to each waterway, and different functions of the water softener are realized by controlling each waterway.

[0143] In specific settings, the water softener valve 100 is used to control the flow direction of water (including raw water, soft water, sewage, etc.) in the water softener to achieve corresponding functions. Figure 29As shown, the water softener further includes a salt tank 500. As described above, resin particles are filled in the resin tank 400. 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 water softening valve 100. Salt water is stored in the salt tank 500, and the salt tank 500 is connected to the water softening valve 100. The salt tank 500 and the resin tank 400 are connected through the water softening valve 100. The salt tank 500 is adapted to supply salt water to the resin tank 400 to clean and restore the resin so that the resin can continue to adsorb calcium and magnesium ions. The water softening valve 100 is used to control the water flow direction. For example, the water softening valve 100 can control the raw water to flow into the resin tank 400 for filtration to reduce the water hardness and form softened water.

[0144] It can be understood that, as Figures 4-12 shown, the water inlet pipe 112 is adapted to be connected to a water source to supply raw water; the water outlet pipe 113 is adapted to be connected to a user end to supply water to the user for use; the inlet pipe 114 is adapted to be connected to the inlet of the resin tank 400, and the outlet pipe 115 is adapted to be connected to the outlet of the resin tank 400. In the water softener of this embodiment, at the corresponding positions, the corresponding water paths are switched to the connected state to convey water to the corresponding positions. In this way, by rotating the valve core assembly 140 to the required position, the corresponding water paths are switched to the connected state, realizing the control of the water flow direction in the water softener and simplifying the control logic. Moreover, by using the water softening valve 100 to control the water paths in the water softener, the integration degree of the control structure of the water softener is improved. In some embodiments, the cross-section of the valve cavity 111 is circular, the valve seat 116 is columnar, and the valve seat 116 is arranged at the central position of the valve cavity 111.

[0145] At the service position, as Figures 19-22 shown, at least the service water path is in the connected state. The water softening valve 100 can convey the raw water into the resin tank 400, so that the resin particles can adsorb calcium and magnesium ions in the raw water to produce softened water. At the salt absorption position, as Figures 25-29 shown, at least the salt absorption water path is in the connected state. The water softening valve 100 can convey the salt water in the salt tank 500 into the resin tank 400. The salt water is used to displace the calcium and magnesium ions adsorbed on the resin to restore the resin so that the resin can continue to adsorb calcium and magnesium ions. At the bypass position, as Figure 23 、 Figure 24 shown, at least the bypass water path is in the connected state. The water softening valve 100 can directly convey the raw water to the user end. It can be understood that the water use requirements of users are diverse, and the requirements for water hardness are different in different scenarios.

[0146] For example, when flushing a toilet, the influence of water hardness can be ignored, and the user can use raw water for flushing. At this time, the valve core assembly 140 is switched to the bypass position to provide raw water for flushing the toilet, which can reduce the resin filtration process and thus reduce the consumption of resin. At the backwash position, as Figures 31-34 shown, at least the backwash water path is in a connected state. At this time, the soft water valve 100 delivers water into the resin tank 400 to flush the resin, remove the broken resin, and increase the gap between the resin particles. After switching to the service position, the resin is in full contact with the raw water to adsorb calcium and magnesium ions, improving the filtration effect. At the water replenishment position, at least the water replenishment water path is in a connected relationship, and the soft water valve 100 is adapted to deliver water into the salt tank 500 to replenish the brine.

[0147] It can be understood that in this embodiment, the valve core assembly 140 is driven to rotate by the driving part 142 to switch between the service position, the salt suction position, the bypass position, the backwash position, and the water replenishment position. The valve core assembly 140 and the valve seat 116 define corresponding water paths to control the water flow direction in the water softener, simplifying the control logic and reducing the operating cost.

[0148] As Figure 6 、 Figure 7 shown, according to some embodiments provided by the present invention, 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 has a spaced-apart water inlet cavity 131 and a second water inlet cavity 132. The water inlet cavity 131 is communicated with the water inlet pipe 114. The water inlet pipe 112 is communicated with both the first water inlet cavity 130 and the second water inlet cavity 132. A bypass cavity 133 is provided in the valve seat 116, and the bypass cavity 133 is communicated with the water outlet pipe 113. The bypass cavity 133 is spaced apart from the second water inlet cavity 132. The water inlet cavity 131 is communicated with the first water inlet cavity 130 or the second water inlet cavity 132 through the valve core assembly 140. The first water inlet cavity 130, the second water inlet cavity 132, the valve core assembly 140, and the water inlet cavity 131 jointly define a service water path. Raw water is delivered into the first water inlet cavity 130 and the second water inlet cavity 132 through the water inlet pipe 112, flows through the valve core assembly 140 to the water inlet cavity 131, and is delivered to the inlet of the resin tank 400 through the water inlet pipe 114.

[0149] The bypass chamber 133 is communicated with the first water inlet chamber 130 or the second water inlet chamber 132 through the valve core assembly 140. The first water inlet chamber 130, the second water inlet chamber 132, the valve core assembly 140 and the bypass chamber 133 jointly define a bypass water path. Raw water is conveyed to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112, flows into the bypass chamber 133 through the valve core assembly 140, and finally flows out through the water outlet pipe 113 to be provided to the user. In this way, the raw water can be conveyed into the resin tank 400 through the service water path for filtration to provide soft water, or the raw water can be provided to the user through the bypass water path, improving the flexibility of the water softener.

[0150] According to some embodiments of the present invention, the water outlet pipe 113 and the tank outlet pipe 115 are communicated through a bypass check valve 137 to make the tank outlet pipe 115 conduct unidirectionally to the water outlet pipe 113. As Figure 5 shown in Figure 23 the figure, the water softening valve 100 further includes a bypass check valve 137. The water outlet pipe 113 is communicated with the tank outlet pipe 115. The soft water generated by the resin tank 400 flows through the tank outlet pipe 115 to the water outlet pipe 113, and then is conveyed to the user end for use. In this way, the water flowing in the water outlet pipe 113 includes the soft water generated in the resin tank 400 and the raw water flowing out through the bypass chamber 133. The bypass check valve 137 can be arranged in the water outlet pipe 113 or in the tank outlet pipe 115. The bypass check valve 137 can conduct unidirectionally, so that the water flows unidirectionally from the tank outlet pipe 115 to the water outlet pipe 113, preventing the water in the water outlet pipe 113 from flowing back into the resin tank 400. The connection position between the bypass chamber 133 and the water outlet pipe 113 is located between the bypass check valve 137 and the outlet of the water outlet pipe 113 to prevent the raw water in the bypass chamber 133 from flowing to the tank outlet pipe 115. As Figure 5 shown in Figure 23 the figure, in some embodiments, the water softening valve 100 further includes a flow meter 183. The flow meter 183 is arranged in the water outlet pipe 113 and is closer to the outlet of the water outlet pipe 113 than the connection position between the bypass chamber 133 and the water outlet pipe 113. The flow meter 183 is used to detect the water flow output by the water outlet pipe 113. As Figure 23 shown in the figure, the flow meter 183 is inserted into the water outlet pipe 113 and is fixedly connected to the water outlet pipe 113 by plugging.

[0151] As Figure 14 shown in Figure 22As shown, according to some embodiments of the present invention, a sewage discharge control component 250 is provided inside the adapter component 200. The sewage discharge control component 250 is arranged in the sewage discharge pipeline 2107. The sewage discharge control component 250 is used to control the on-off of the sewage discharge pipeline 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 meshes with the driving gear 1432. At least one driving block 1433 is provided on the driven gear 1431. The driving block 1433 is used to cooperate with the sewage discharge control component 250 to open the sewage discharge pipeline 2107. The rotating shaft 150 is connected to the driven gear 1431; wherein, the rotating shaft 150 is connected to the valve core component 140 to drive the valve core component 140 to control the water path switching. The sewage discharge control component 250 realizes the opening of the sewage discharge pipeline 2107 through the driving block 1433 on the driven gear 1431. Specifically, when the sewage discharge pipeline 2107 needs to be opened, the driving block 1433 can squeeze the sewage discharge control component 250 through the rotation of the driven gear 1431, thereby realizing the opening of the sewage discharge pipeline 2107. For example, at the salt absorption position, the salt absorption water pipeline is in a connected state. The soft water valve 100 can transport the salt water in the salt tank 500 to the resin tank 400. The salt water is used to displace the calcium and magnesium ions adsorbed on the resin to restore the resin, so that the resin can continue to adsorb calcium and magnesium ions. The treated wastewater enters the sewage discharge pipeline 2107 through the adapter component 200. At this time, the driving block 1433 squeezes the sewage discharge control component 250 to open the sewage discharge pipeline 2107, realizing the direct discharge of sewage. Thus, a driving part 142 can be used to drive the water path switching and the control of the opening of the sewage discharge pipeline 2107, simplifying the control logic.

[0152] When specifically arranged, as Figure 5 shown, the driving part 142 is a driving motor. The driving motor is fixedly connected to the valve body 110. The driving motor can be fixedly connected to the valve body 110 by screws. The driven gear 1431 is larger than the driving gear 1432. The two gears mesh. The driving motor drives the driving gear 1432 to rotate. The driving gear 1432 drives the driven gear 1431 to rotate. The driven gear 1431 drives the rotating shaft 150 to rotate, and then can drive the moving piece 160 inside the valve core component 140 to rotate. The transmission ratio of the driving gear 1432 to the transmission gear is greater than 1, that is, the number of teeth of the driving gear 1432 is greater than the number of teeth of the transmission gear, so as to amplify the driving torque and provide sufficient power to drive the rotating shaft 150 and the moving piece 160 to rotate.

[0153] As Figure 5 、 Figure 11 and Figure 12As shown, according to some embodiments of the present invention, the valve core assembly 140 includes a moving piece 160. The moving piece 160 is fixedly connected to the rotating shaft 150. The rotating shaft 150 drives the moving piece 160 to rotate. The moving piece 160 is disposed on the valve seat 116. The moving piece 160 cooperates with the valve seat 116 to define a service water path, a brine suction water path, a bypass water path, a backwash water path, and a make-up water path. The driving part 142 is connected to the valve body 110. The rotating shaft 150 is rotatably connected to the valve body 110. The rotating shaft 150 is in transmission connection with the driving part 142. The moving piece 160 is fixedly connected to the rotating shaft 150. The rotating shaft 150 drives the moving piece 160 to rotate. The moving piece 160 is adapted to be attached to the top of the valve seat 116. By driving the rotating shaft 150 to rotate through the driving assembly, the rotating shaft 150 drives the moving piece 160 to rotate, so that the moving piece 160 cooperates with the valve seat 116, thereby defining the corresponding water path. For example, rotating the moving piece 160 makes the moving piece 160 cooperate with the inlet tank cavity 131. Thus, the first inlet cavity 130, the second inlet cavity 132, the moving piece 160, and the inlet tank cavity 131 jointly define the service water path.

[0154] As Figure 5 shown, according to some embodiments of the present invention, the valve body 110 includes a valve body portion and a valve plug cover 118. The valve cavity 111 is disposed inside the valve body portion, and one side of the valve cavity 111 is open. The rotating shaft 150 passes 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 driving motor are both located outside the valve cavity 111. The gear assembly 143 is formed by the driving gear 1432 meshing with the transmission gear. The driving motor is the driving part 142. The valve plug cover 118 covers the open end of the valve cavity 111 to seal the valve cavity 111. The rotating shaft 150 passes through the valve plug cover 118, and the gear assembly 143 is located outside the valve cavity 111. As Figure 6 shown, a receiving groove 117 is provided on the valve body portion. The driving motor is adapted to be received in the receiving groove 117. The valve plug cover 118 is adapted to cover the receiving groove 117. 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.

[0155] As Figure 5As shown, according to some embodiments of the present invention, the rotating shaft 150 includes a vertical shaft 151 and a connecting disk 152, one end of the vertical shaft 151 is connected to the driving assembly, the vertical shaft 151 is inserted into the valve cavity 111, and one end of the vertical shaft 151 is fixedly connected to the driven gear 1431. The connecting disk 152 is arranged at the other end of the vertical shaft 151, and the connecting disk 152 is stacked and fixedly connected with the moving plate 160. The connecting disk 152 is in a disk shape to match the moving plate 160, and the diameter of the connecting disk 152 can be less than or equal to the diameter of the moving plate 160. In some embodiments, a pressure block is provided on the side facing the valve plug cover 118, and the pressure block is located in the valve cavity 111, and the pressure block abuts against the connecting disk 152 to limit the rotating shaft 150 in the axial direction.

[0156] like Figure 5 and Figure 11 As shown, according to some embodiments of the present invention, a first locking portion 153 is provided on the connecting disk 152, and a second locking portion 167 cooperating 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 cooperates with the second locking portion to circumferentially limit the movable plate 160, so that the rotating shaft 150 can drive the movable plate 160 to rotate.

[0157] There can be multiple first clips and multiple second clips, multiple first clips are distributed along the circumferential direction of the connecting disk 152, and multiple second clips are distributed along the circumferential direction of the moving 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 is adapted to the second positioning portion to position the relative position of the moving plate 160 and the connecting disk 152 in the circumferential direction to avoid misalignment of the rotating shaft 150 and the moving plate 160 during assembly. For example, Figure 11 As shown, 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 that is a groove is matched with the second clip that is a protrusion to circumferentially position the moving plate 160 and the connecting plate 152, so that the relative positions of the two in the circumferential direction are uniquely determined for easy assembly.

[0158] See also Figure 5As shown, according to some embodiments of the present invention, the valve body 110 further includes a control board 119. The control board 119 is fixed relative to the valve seat 116, and the control board 119 can be fixedly connected to the valve plug cover 118. The control board 119 is sleeved on the rotating shaft 150, and the control board 119 is located between the valve plug cover 118 and the gear assembly 143. A Hall sensor 1191 is provided on the control board 119, and a magnetic member is provided on the gear assembly 143. The Hall sensor 1191 is used to sense the position of the magnetic member. Thus, the drive motor can be controlled according to the position of the magnetic member detected by the Hall sensor 1191, and then the rotation angle of the moving piece 160 can be controlled so that the moving piece 160 rotates to the corresponding position.

[0159] As Figure 5 shown, in some embodiments, there may be multiple Hall sensors 1191, and the multiple Hall sensors 1191 are spaced apart along the circumferential direction of the rotating shaft 150. The positions where the multiple Hall sensors 1191 are located respectively correspond to the service position, the salt absorption position, the bypass position, the backwash position, and the water replenishment position. When the magnetic member moves to the position closest to one of the Hall sensors 1191, the valve core assembly 140 switches to the corresponding position. For example, the position of one of the multiple Hall sensors 1191 corresponds to the service position. When the magnetic member moves to the position closest to this Hall sensor 1191, the valve core assembly 140 switches to the service position. The orthographic projection of the movement trajectory of each Hall sensor 1191 and the magnetic member on the control board 119 can coincide to improve the detection accuracy of the Hall sensor 1191. When the valve core assembly 140 switches to the service position, the magnetic member is opposite to the corresponding Hall sensor 1191. Refer to Figure 5 shown, the water softening valve 100 further includes an upper cover 101. The upper cover 101 covers the valve body 110 and is fixedly connected to the valve body 110. The upper cover 101 plays a role of sealing and protecting. An installation space is defined between the upper cover 101 and the valve body 110. The open end of the valve seat 116 is located in the installation space, and the drive assembly and the control board 119 are both received in the installation space.

[0160] As Figure 5 、 Figure 8 And Figure 9 shown, according to some embodiments of the present invention, the valve core assembly 140 further includes a stationary piece 170. The stationary piece 170 is attached to the valve seat 116, and the stationary piece 170 is clamped between the moving piece 160 and the valve seat 116. The stationary piece 170 is fixed relative to the valve seat 116, the moving piece 160 is rotatable relative to the stationary piece 170, and the stationary piece 170 can space the moving piece 160 from the valve seat 116, avoiding abrasion of the valve seat 116 during the rotation of the stationary piece 170, extending the service life of the valve body 110, and the stationary piece 170 has good replaceability, which is convenient for later maintenance. As Figure 8As shown, the fixed plate 170 is provided with a fixed bypass hole 171 corresponding to the bypass chamber 133, and the movable plate 160 cooperates with the fixed plate 170 and the valve seat 116 to define a service waterway, a salt water absorption channel, a bypass waterway, a backwash waterway and a water replenishment waterway. Specifically, the first water inlet chamber 130, the second water inlet chamber 132, the movable bypass hole 162, the fixed bypass hole 171 and the bypass chamber 133 jointly define the bypass waterway. The fixed water inlet hole 173 and the fixed tank inlet hole 174 are also provided on the fixed plate 170. The fixed water inlet hole 173 is connected to the second water inlet chamber 132, and the fixed tank inlet hole 174 is connected to the tank inlet chamber 131.

[0161] like Figure 5 and Figure 10 As shown, in some embodiments, a sealing gasket 180 is provided between the stator 170 and the valve seat 116, and 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, so that the stator 170 and the valve seat 116 can be sealed to prevent water seepage, and can also be fixed relative to the valve seat 116 to prevent the stator 170 from sliding with the moving plate 160. The sealing gasket 180 can be a rubber part, and the sealing gasket 180 can produce a certain deformation to fit closely with the valve seat 116 and the stator 170 to prevent water seepage.

[0162] like Figure 6 and Figure 9 As shown, according to some embodiments of the present invention, the inner wall of the valve cavity 111 is provided with a first fixing portion 1111, and the periphery of the stator 170 is provided with a second fixing portion 172, and the second fixing portion 172 is engaged with the first fixing portion 1111 to position the stator 170 in the circumferential direction to 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 body, and the other is a protrusion. Figure 6 and Figure 9 In the example, the first fixing portion 1111 is a protrusion, and the second fixing portion 172 is a groove.

[0163] In some embodiments, there are multiple first fixing parts 1111 and multiple second fixing parts 172, and the multiple first fixing parts 1111 are spaced apart along the circumferential direction of the valve cavity 111, and the second fixing parts 172 are spaced apart along the circumferential direction of the stator 170. Among the multiple first fixing parts 1111, there is a first fixing part 1111 whose width is different from the widths of the other first fixing parts 1111, and among the multiple second fixing parts 172, there is a second fixing part 172 whose width is different from the widths of the other second fixing parts 172. The first fixing part 1111 and the second fixing part 172 cooperate to locate the relative positions of the stator 170 and the valve seat 116 in the circumferential direction, so as to avoid the stator 170 being misaligned with the valve seat 116 during installation, resulting in failure to seal.

[0164] For example, as Figure 6 shown, there are three first fixing parts 1111, all of which are protrusions. As Figure 9 shown, there are three second fixing parts 172, all of which are protrusions. The width of one of the first fixing parts 1111 in the circumferential direction is greater than that of the other two first fixing parts 1111 in the circumferential direction, and the width of one of the second fixing parts 172 in the circumferential direction is greater than that of the other two second fixing parts 172 in the circumferential direction. The first fixing part 1111 and the second fixing part 172 cooperate to position the relative positions of the stationary piece 170 and the valve seat 116 in the circumferential direction. In this way, it is convenient to install the stationary piece 170, avoiding the sealing failure caused by the misalignment of the installation of the stationary piece 170 and preventing water leakage of the valve seat 116.

[0165] See Figure 11 and Figure 12 shown, according to some embodiments of the present invention, the moving piece 160 is provided with spaced-apart moving water inlet holes 161 and moving bypass holes 162. In the service position, the first water inlet chamber 130 and the second water inlet chamber 132 are communicated with the water inlet chamber 131 through the moving water inlet holes 161. The first water inlet chamber 130, the second water inlet chamber 132, the moving water inlet holes 161 and the water inlet chamber 131 define a service water path. At this time, the raw water is transported to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 and the second water inlet chamber 132 flows to the water inlet chamber 131 through the moving water inlet holes 161. The raw water in the water inlet chamber 131 is transported to the inlet of the resin tank 400 through the water inlet pipe 114. The raw water contacts the resin to reduce the calcium and magnesium ion concentration and form soft water. The soft water flows into the outlet pipe 115 from the outlet of the resin tank 400, and unidirectionally flows to the water outlet pipe 113 through the outlet pipe 115, and finally is transported to the user end through the pipeline.

[0166] In the bypass position, the first water inlet chamber 130 and the second water inlet chamber 132 are communicated with the bypass chamber 133 through the moving bypass holes 162. The first water inlet chamber 130, the second water inlet chamber 132, the moving bypass holes 162 and the bypass chamber 133 define a bypass water path. The raw water is transported to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 and the second water inlet chamber 132 flows into the bypass chamber 133 through the moving bypass holes 162. The raw water in the bypass chamber 133 flows out through the water outlet pipe 113 and is transported to the user end through the pipeline. As Figure 6 shown, the water inlet chamber 131 and the bypass chamber 133 are spaced apart along the circumferential direction of the valve seat 116, and the moving water inlet holes 161 and the moving bypass holes 162 are spaced apart in the circumferential direction of the moving piece 160. By rotating the moving piece 160, it is possible to switch the connection or disconnection between the moving water inlet holes 161 and the water inlet chamber 131, and switch the connection or disconnection between the moving bypass holes 162 and the bypass chamber 133.

[0167] See Figure 11 As shown, according to some embodiments of the present invention, the surface of the moving plate 160 facing away from the valve seat 116 is provided with a water inlet channel 163, and the water inlet channel 163 communicates the moving water inlet hole 161 with the first water inlet cavity 130 to guide the water in the first water inlet cavity 130 into the moving water inlet hole 161. In some embodiments, the surface of the moving plate 160 facing away from the valve seat 116 is further provided with a communication port 164, and the communication port 164 is used to communicate the water inlet channel 163 with the first water inlet cavity 130. The communication port 164 is provided at the edge of the moving plate 160 and extends along the radial direction of the moving plate 160. There are multiple communication ports 164 for communicating the water inlet channel 163 with the first water inlet cavity 130, and the multiple communication ports 164 are spaced apart along the circumferential direction of the moving plate 160. Some of the communication ports 164 communicate with the moving water inlet hole 161 or the moving bypass hole 162, and the water in the first water inlet cavity 130 can flow from multiple directions to the moving water inlet hole 161 and the moving bypass hole 162. The multiple communication ports 164 can be evenly distributed along the circumferential direction of the moving plate 160 to evenly introduce water into the moving water inlet hole 161 and the moving bypass hole 162. In this way, after the connecting disc 152 and the moving plate 160 are connected, the water in the first water inlet cavity 130 can flow to the moving water inlet hole 161 and the moving bypass hole 162 through the water inlet channel 163 and the communication port 164, and then flow to the water inlet cavity 131 and the bypass cavity 133. When the water flows in the water inlet channel 163 and the communication port 164, the water generates pressure on the moving plate 160, causing the moving plate 160 to closely fit with the valve seat 116, which is beneficial to simplifying the fixing structure of the moving plate 160. As Figure 11 shown, the water inlet channel 163 can extend along an arc, that is, the water inlet channel 163 is arc-shaped. One end of the arc-shaped water inlet channel 163 communicates with the moving water inlet hole 161, and the other end communicates with the moving bypass hole 162.

[0168] As Figures 19-22 shown, where Figure 19 is a schematic structural diagram of the water softener 100 when the valve core assembly 140 is in the service position. Figure 20 is a schematic diagram of the relative positions of the moving plate 160 and the fixed plate 170 when the valve core assembly 140 is in the service position. Figure 21 is another perspective schematic diagram of the relative positions of the moving plate 160 and the fixed plate 170 when the valve core assembly 140 is in the service position. Figure 22 is a cross-sectional view of the water softener when the valve core assembly 140 is in the service position, and the arrows in the figure indicate the water flow direction.

[0169] When the valve core assembly 140 is in the service position, the first water inlet chamber 130, the second water inlet chamber 132, the communication port 164, the water inlet passage 163, the movable water inlet hole 161, the fixed water inlet hole 174 and the water inlet chamber 131 jointly define a service water path. The movable water inlet hole 161 communicates with the water inlet chamber 131 through the fixed water inlet hole 174, the movable water inlet hole 161 communicates with the first water inlet chamber 130 through the water inlet passage 163 and the communication port 164, and the movable 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 water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 can flow into the water inlet passage 163 through the communication port 164 (such as Figure 19 the Figure 20 flow direction shown by arrow 1 in Figure 19 ), and then flow into the movable water inlet hole 161 (such as Figure 20 the

[0170] flow direction shown by arrow 2 in Figure 22 ). The raw water in the second water inlet chamber 132 can flow into the water inlet passage 163 through the fixed water inlet hole 173 and the movable bypass hole 162, and then flow into the movable water inlet hole 161. After the raw water flows into the movable water inlet hole 161, it flows into the water inlet chamber 131 through the fixed water inlet hole 174. The raw water in the water inlet chamber 131 is transported to the inlet of the resin tank 400 through the water inlet pipe 114. Figure 22 As

[0171] shown, both the inlet and the outlet of the resin tank 400 are provided at one end of the resin tank 400. A central pipe 410 is provided in the resin tank 400. One end of the central pipe 410 communicates with the outlet of the resin tank 400, and the other end of the central pipe 410 communicates with the resin tank 400. Resin is stored in the resin tank 400 and is located outside the central pipe 410. Raw water enters the resin tank 400 from the inlet of the resin tank 400 (such as Figure 23 the Figure 24 flow direction shown by arrow 2 in Figure 24Cross-sectional view of the water softener when the valve core assembly 140 is in the bypass position. The arrows in the figure indicate the water flow direction. In the bypass position, the first water inlet chamber 130, the second water inlet chamber 132, the communication port 164, the water inlet passage 163, the movable bypass hole 162, the fixed bypass hole 171, and the bypass chamber 133 jointly define a bypass water path. The movable bypass hole 162 communicates with the bypass chamber 133 through the fixed bypass hole 171. The movable bypass hole 162 communicates with the first water inlet chamber 130 through the water inlet passage 163 and the communication port 164. The movable water inlet hole 161 communicates with the second water inlet chamber 132 through the fixed water inlet hole 173. Raw water is delivered to the first water inlet chamber 130 and the second water inlet chamber 132 through the water inlet pipe 112. The raw water in the first water inlet chamber 130 flows into the movable bypass hole 162 through the communication port 164 and the water inlet passage 163. The raw water in the second water inlet chamber 132 flows into the movable bypass hole 162 through the fixed water inlet hole 173, the movable water inlet hole 161, and the water inlet passage 163. The raw water flowing into the movable 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 from the water outlet pipe 113 and is delivered to the user end through a pipeline. As Figure 24 shown, during this process, the raw water does not pass through the resin tank 400. In this way, water can be supplied flexibly according to user needs during use, and the consumption of resin can be reduced.

[0172] See Figure 6 shown. According to some embodiments of the present invention, a salt suction chamber 134 and a salt suction communication chamber 135 are provided on the valve seat 116 at intervals. The salt suction chamber 134 is adapted to communicate with the salt tank 500. As Figure 12 shown, a movable salt suction water distribution hole 165 is provided on the movable plate 160. The movable salt suction water distribution hole 165 is a blind hole 168, and the movable salt suction water distribution hole 165 is provided on the surface of the movable plate 160 facing the valve seat 116. The salt suction communication chamber 135 is adapted to communicate with the movable salt suction water distribution hole 165. The movable water inlet hole 161 penetrates the movable plate 160 along the thickness direction of the movable plate 160. The movable salt suction water distribution hole 165 is spaced apart from the movable water inlet hole 161. In the salt suction position, the movable water inlet hole 161 communicates with the movable salt suction water distribution hole 165 through the salt suction communication chamber 135. The movable salt suction water distribution hole 165 communicates with the salt suction chamber 134 and the bypass chamber 133 respectively. The movable water inlet hole 161, the salt suction communication chamber 135, the movable salt suction water distribution hole 165, and the salt suction chamber 134 define a salt suction water path. The movable water inlet hole 161, the salt suction communication chamber 135, the movable salt suction water distribution hole 165, and the bypass chamber 133 define a bypass water path. In this way, in the salt suction position, raw water can be provided to the user through the bypass water path.

[0173] As Figure 6 compared with Figure 12As shown, the salt absorption communication cavity 135 extends along the radial direction of the valve seat 116, and one end of the salt absorption communication cavity 135 is located at the center of the valve seat 116; the moving salt absorption water distribution hole 165 extends along the radial direction of the moving piece 160, and one end of the moving salt absorption water distribution hole 165 is located at the center of the moving piece 160. In this way, during the rotation of the moving piece 160, one end of the salt absorption communication cavity 135 remains in communication with one end of the moving salt absorption water distribution hole 165, and the salt absorption communication cavity 135 and the moving salt absorption water distribution hole 165 can play a role in communicating the through hole on the moving piece 160 with the chamber on the valve seat 116.

[0174] See Figures 25 to 29 As shown, the valve core assembly 140 in the figure is in the salt absorption position. Among them, Figure 25 is a schematic structural diagram of the soft water valve 100; Figure 26 is a schematic diagram of the internal structure of the valve chamber 111, in which the moving piece 160 and the fixed piece 170 are not shown, and the arrows in the figure indicate the flow direction of water; Figure 27 is a schematic diagram of the relative position of the moving piece 160 and the fixed piece 170; Figure 28 is another perspective schematic diagram of the relative position of the moving piece 160 and the fixed piece 170, and the arrows in the figure indicate the flow direction of water; Figure 29 is a sectional view of the water softener, and the arrows in the figure indicate the flow direction of water.

[0175] At the salt absorption position, the moving water inlet hole 161 is communicated with the salt absorption communication cavity 135 through the fixed salt absorption communication hole 176 on the fixed piece 170, the salt absorption communication cavity 135 is communicated with the moving salt absorption water distribution hole 165 through the fixed salt absorption communication hole 176, the moving salt absorption water distribution hole 165 is communicated with the bypass cavity 133 through the fixed bypass hole 171, and the moving salt absorption water distribution hole 165 is communicated with the salt absorption cavity 134 through the fixed salt absorption hole 175. The moving bypass hole 162 is communicated with the second water inlet cavity 132 through the moving and fixed water inlet hole 173.

[0176] Raw water is input into the first water inlet cavity 130 and the second water inlet cavity 132 through the water inlet pipe 112. The raw water in the first water inlet cavity 130 flows through the communication port 164 and the water inlet channel 163 to the moving water inlet hole 161, and the raw water in the second water inlet cavity 132 flows through the fixed water inlet hole 173, the moving bypass hole 162 and the water inlet channel 163 into the moving water inlet hole 161. The raw water in the moving water inlet hole 161 flows into the salt absorption communication cavity 135 through the fixed salt absorption communication hole 176 (as Figure 27 shown by Figure 28 the arrow 1 in Figure 28Another 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 outlet pipe 113 to be provided to the user.

[0177] According to some embodiments of the present invention, the salt absorption chamber 134 is selectively connected to the salt box 500. When in the salt absorption position: the salt absorption chamber 134 is connected to the salt box 500, the soft water valve 100 is in the salt absorption mode, and the salt water in the salt box 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 box 500, and the soft water valve 100 is in the slow washing mode. At this time, the salt box 500 stops providing salt water, and the raw water in the salt absorption chamber 134 is transported to the resin tank 400 to wash the resin tank 400 to wash away the salt in the resin. Figure 7 As shown, in some embodiments, the soft water valve 100 further includes a jet tube 181, an ejector 240 is provided in the jet tube 181, the jet tube 181 is connected to the valve body 110, and the jet tube 181 is in communication with the salt absorption chamber 134. The jet tube 181 is in communication with both the salt box 500 and the resin tank 400. When the salt absorption chamber 134 is in communication with the salt box 500, the ejector 240 can transport the water in the salt absorption chamber 134 and the salt water in the salt box 500 to the resin tank 400; when the salt absorption chamber 134 is disconnected from the salt box 500, the jet tube 181 can transport the water in the salt absorption chamber 134 to the resin tank 400 to flush the resin.

[0178] See also Figure 29 As shown, according to some embodiments of the present invention, the soft water valve 100 further includes a sewage discharge path 2107, and the sewage discharge path 2107 is selectively connected to the tank inlet pipe 114, and the tank inlet pipe 114 is connected to the inlet of the resin tank 400, so that the sewage discharge path 2107 is connected to the resin tank 400 through the tank inlet pipe 114. When in the salt absorption position, the sewage discharge path 2107 is connected to the tank inlet pipe 114. The sewage generated by cleaning the resin in the salt absorption mode and the slow washing mode can be discharged through the sewage discharge path 2107. In some embodiments, the adapter assembly 200 has a sewage discharge control assembly 250, and the sewage discharge control assembly 250 is used to control the connection and disconnection of the sewage discharge path 2107 and the tank inlet pipe 114. In a specific example, as Figure 29 As shown, the sewage control assembly 250 is arranged at the place where the sewage discharge path 2107 is connected to the tank inlet pipe 114, and a driving block 1433 is arranged on the bottom surface of the driven gear 1431. When the valve core assembly 140 is located at the salt absorption position, the driving block 1433 pushes the pressure rod to move so that the sewage discharge path 2107 is connected to the tank inlet pipe 114.

[0179] like Figure 29As shown, the jet pipe 181 communicates with the central pipe 410 of the resin tank 400. When the soft water valve 100 is in the brine suction mode, the pressure lever is in the open state. A part of the raw water input to the soft water valve 100 is conveyed to the jet pipe 181 through the brine suction water path (as Figure 29 shown by the flow direction of arrow 2 in Figure 29 ). The jet pipe 181 mixes the brine and the raw water and conveys the mixture to the outlet of the resin tank 400. The mixed brine flows through the central pipe 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 adsorption capacity of the resin. The mixed brine after cleaning the resin flows out from the inlet of the resin tank 400 and is discharged through the sewage drainage water path 2107. Another part of the raw water input to the soft water valve 100 is conveyed to the water outlet pipe 113 through the bypass water path (as Figure 30 shown by the flow direction of arrow 3 in

[0180] ) to be provided to the user. As Figure 6 shown in Figure 12 and Figure 6 , according to some embodiments of the present invention, the moving vane 160 is provided with a moving backwash hole 166 penetrating along its thickness direction, the seat body is provided with a backwash cavity 136, and the valve body 110 is provided with a backwash pipe 182. The backwash pipe 182 communicates with the backwash cavity 136, and the backwash pipe 182 communicates with the central pipe 410 of the resin tank 400. In the Figure 12 example, the backwash cavity 136 and the brine suction cavity 134 are spaced apart in the radial direction of the valve seat 116. In the

[0181] example, the moving water inlet hole 161, the moving backwash hole 166 and the moving bypass hole 162 are sequentially spaced apart in the circumferential direction of the moving vane 160. In the backwash position, the backwash cavity 136 communicates with the moving bypass hole 162 to define a backwash water path; the moving backwash hole 166 communicates with the bypass cavity 133 to define a bypass water path. In the backwash position, a part of the raw water input to the soft water valve 100 is conveyed into the resin tank 400 through the backwash water path and the backwash pipe 182 to backwash the resin, wash away the broken resin, and increase the gap between the resin particles. In this way, the resin particles are in full contact with the raw water in the service position, improving the adsorption effect on calcium and magnesium ions in the raw water. Another part of the raw water input to the soft water valve 100 is output through the bypass water path and the water outlet pipe 113 to be used by the user, realizing uninterrupted water supply. When the valve core assembly 140 is in the backwash position, the sewage drainage water path 2107 communicates with the resin tank 400 to discharge the sewage generated during the backwash process.

[0182] As shown Figures 31 to 34 in the figure, the valve core assemblies 140 are all in the backwash position at this time, and the arrows in the figure all indicate the flow direction of water. Among them, Figure 31 is a schematic structural diagram of the soft water valve 100; Figure 32 is a schematic diagram of the relative position of the moving piece 160 and the fixed piece 170; Figure 33 is a schematic diagram of another perspective of the relative position of the moving piece 160 and the fixed piece 170; Figure 34 is a cross-sectional view of the water softener.

[0183] In the backwash position, the valve core assembly 140 and the valve seat 116 define a backwash water path and a bypass water path. The moving bypass hole 162 communicates with the backwash cavity 136 through the fixed backwash hole 177, the moving backwash hole 166 communicates with the bypass cavity 133 through the fixed bypass hole 171, and the moving water inlet hole 161 communicates with the second water inlet cavity 132 through the fixed water inlet hole 173. The raw water is transported to the first water inlet cavity 130 and the second water inlet cavity 132 through the water inlet pipe 112 (as Figure 34 shown by the arrow 1 in the figure). The raw water in the first water inlet cavity 130 flows through the communication port 164 and the water inlet channel 163 into the moving bypass hole 162 and the moving backwash hole 166, and the raw water in the second water inlet cavity 132 flows through the fixed water inlet hole 173, the moving water inlet hole 161 and the water inlet channel 163 into the moving bypass hole 162 and the moving backwash hole 166.

[0184] The raw water flowing into the moving bypass hole 162 flows into the backwash cavity 136 through the fixed backwash hole 177 (as Figure 34 shown by the arrow 2 in the figure), and thus flows through the backwash pipe 182 into the central pipe 410 of the resin tank 400. The raw water is transported to the other end of the resin tank 400 through the central pipe 410 to wash the resin. At the backwash position, the sewage discharge water path 2107 is communicated with the resin tank 400 of the inlet pipe 114. The sewage generated after the raw water washes the resin flows out through the inlet of the resin tank 400 and is discharged from the sewage discharge water path 2107. In some embodiments, a plurality of push blocks are provided on the driven gear 1431. When the valve core assembly 140 moves to the backwash position, one of the push blocks pushes the pressure rod, so that the sewage discharge water path 2107 is communicated with the inlet pipe 114. The raw water flowing into the moving backwash hole 166 flows into the bypass cavity 133 through the fixed bypass hole 171 (as Figure 34 shown by the arrow 3 in the figure), and then is output from the water outlet pipe 113 to be provided to the user. Thus, during the backwash process, the water softener can supply water continuously.

[0185] According to some embodiments of the present invention, a water replenishing chamber spaced apart from the brine suction chamber 134 is provided on the valve seat 116. The water softening valve 100 further includes a water replenishing pipe connected to the valve body 110, and the water replenishing chamber is in communication with the water replenishing pipe. And a brine suction check valve 260 is provided between the water replenishing pipe and the jet pipe 181. The brine suction check valve 260 conducts unidirectionally based on the pressure difference between the water replenishing pipe and the jet pipe 181 to control the on-off of the jet pipe 181 and the resin tank 400. For example, in Figure 29 In the example of, when the valve core assembly 140 is in the brine suction position, raw water flows through the brine suction water path into the jet pipe 181, and no water flows through the water replenishing pipe. At this time, the pressure in the jet pipe 181 is greater than the pressure in the water replenishing pipe, and the jet pipe 181 is in communication with the resin tank 400, and raw water can flow from the jet pipe 181 into the resin tank 400.

[0186] In the water replenishing position, the moving water inlet hole 161 is in communication with both the water replenishing chamber and the brine suction chamber 134. The pressure difference between the water replenishing pipe and the jet pipe 181 is zero, and the brine suction check valve 260 blocks the communication between the jet pipe 181 and the resin tank 400, while the jet pipe 181 remains in communication with the salt tank 500. The brine suction chamber 134 replenishes water into the salt tank 500 through the jet pipe 181, and the moving water inlet hole 161, the water replenishing chamber, the brine suction chamber 134, and the jet pipe 181 define a water replenishing water path. It can be understood that the salt tank 500 usually stores salt, and the salt tank 500 needs to maintain a state of "seeing salt but not water" to prevent the resin from failing to be restored due to the inability to provide brine during the use of the salt tank 500. In the water replenishing position, water is replenished into the salt tank 500 through the water replenishing water path to dissolve the salt in the salt tank 500 and replenish the brine.

[0187] In some embodiments, the water replenishing chamber and the backwashing chamber 136 are the same chamber, and the water replenishing pipe and the backwashing pipe 182 are the same pipe, that is, the backwashing chamber 136 is the water replenishing chamber, and the backwashing pipe 182 is the water replenishing pipe. For the convenience of understanding, the structure and working process of the water softening valve 100 in the water replenishing position will be described below by taking the water replenishing chamber and the backwashing chamber 136 as the same chamber and the water replenishing pipe and the backwashing pipe 182 as the same pipe as an example.

[0188] As Figures 35-38 shown, at this time, the valve core assemblies 140 are all in the water replenishing position, and the arrows in the figure all represent the flow direction of water. Among them, Figure 35 is a schematic structural diagram of the water softening valve 100; Figure 36 is a schematic diagram of the relative position of the moving piece 160 and the fixed piece 170; Figure 37Another perspective schematic diagram of the relative positions of the moving sheet 160 and the fixed sheet 170. At the water replenishing position, the moving water inlet hole 161 communicates with the salt absorption cavity 134 through the fixed salt absorption hole 175, and the moving water inlet hole 161 communicates with the backwashing cavity 136 through the fixed backwashing hole 177. The moving backwashing hole 166 communicates with the inlet tank cavity 131 through the fixed inlet tank hole 174. The first water inlet cavity 130, the moving water inlet hole 161, the water replenishing cavity, the salt absorption cavity 134 and the jet pipe 181 define a water replenishing water path. The first water inlet cavity 130, the moving backwashing hole 166 and the inlet tank cavity 131 jointly define a service water path.

[0189] Raw water is transported to the first water inlet cavity 130 and the second water inlet cavity 132 through the water inlet pipe 112. The raw water in the first water inlet cavity 130 flows towards the moving water inlet hole 161 and the moving backwashing hole 166 through the communication port 164 and the water inlet channel 163. A part of the raw water in the moving water inlet hole 161 flows into the backwashing cavity 136 through the fixed backwashing hole 177 and then into the backwashing pipe 182; another part of the raw water in the moving water inlet hole 161 flows into the salt absorption cavity 134 through the fixed salt absorption hole 175 and then into the jet pipe 181. In this way, the pressure of the water in the backwashing pipe 182 on the salt absorption check valve 260 is balanced with the pressure of 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 the jet pipe 181 remains connected to the salt box 500. Thus, the water in the salt absorption cavity 134 is transported to the salt box 500 through the jet pipe 181 to supplement brine. The raw water in the moving backwashing hole 166 flows into the inlet tank cavity 131 through the fixed inlet tank hole 174 and is then transported to the user end through the water outlet pipe 113.

[0190] According to some embodiments of the present invention, a mixing water section is provided between the service position and the salt absorption position. When the valve core assembly 140 rotates to the mixing water section, the valve core assembly 140 and the valve seat 116 jointly define a service water path and a bypass water path. As Figure 6 shown, the inlet tank cavity 131, the salt absorption cavity 134 and the bypass cavity 133 are arranged in sequence in the circumferential direction of the valve seat 116. The service position and the salt absorption position are adjacent. As Figure 20 and Figure 27 shown, the valve core assembly 140 can be switched to the salt absorption position by rotating a certain angle counterclockwise along the direction shown in the figure from the service position. As Figure 40As shown in the figure, within the mixing water section, the moving water inlet hole 161 communicates with the water inlet chamber 131, and the moving water inlet hole 161 communicates with the moving salt suction water distribution hole 165 through the salt suction communication chamber 135. The moving salt suction water distribution hole 165 communicates with the bypass chamber 133. The moving water inlet hole 161 and the water inlet chamber 131 jointly define a service water path, and the moving water inlet hole 161, the salt suction communication chamber 135, the moving salt suction water distribution hole 165, and the bypass chamber 133 jointly define a bypass water path. A part of the raw water input by the input soft water valve 100 is transported into the resin tank 400 through the service water path to replace the calcium and magnesium ions in the raw water to produce soft water, and the soft water is transported to the outlet pipe 113 through the outlet tank pipe 115; another part of the raw water is transported to the outlet pipe 113 through the bypass water path. In this way, within the mixing water section, the water output from the outlet pipe 113 is a mixed water of soft water and raw water. Within the mixing water section, the opening degrees of the service water path and the bypass water path are adjusted through the regulating valve core assembly 140 to adjust the water volume of the soft water and the raw water in the outlet pipe 113, so as to achieve the purpose of adjusting the hardness of the water.

[0191] As Figures 39 to 42 shown, the valve core assembly 140 is located within the mixing water section. Among them, Figure 39 is a schematic structural diagram of the soft water valve 100, and the arrows in the figure indicate the flow direction of water; Figure 40 is a schematic diagram of the relative positions of the moving piece 160 and the fixed piece 170, and the arrows in the figure indicate the flow direction of water; Figure 41 is another perspective schematic diagram of the relative positions of the moving piece 160 and the fixed piece 170; Figure 42 is a sectional view of the water softener.

[0192] Within the mixing water section, the moving water inlet hole 161 communicates with the water inlet chamber 131 through the fixed water inlet hole 174, and the moving water inlet hole 161 communicates with the salt suction communication chamber 135 through the fixed salt suction communication hole 176. The salt suction communication chamber 135 communicates with the moving salt suction water distribution hole 165, and the moving salt suction water distribution hole 165 communicates with the bypass chamber 133 through the fixed bypass hole 171. The moving bypass hole 162 communicates with the second water inlet chamber 132 through the fixed water inlet hole 173. At this time, the raw water is input into the first water inlet chamber 130 and the second water inlet chamber 132 through the inlet pipe 112. The raw water in the first water inlet chamber 130 flows towards the moving water inlet hole 161 through the communication port 164 and the water inlet channel 163, and the raw water in the second water inlet chamber 132 flows towards the moving water inlet hole 161 through the fixed water inlet hole 173, the moving bypass hole 162, and the water inlet channel 163.

[0193] A part of the raw water in the water inlet hole flows into the water inlet chamber 131 through the fixed water inlet hole 174 (as Figure 40 shown by Figure 41 the flow direction of arrow 1 in Figure 42in the flowing direction indicated by arrow 1), the raw water enters the resin tank 400 and contacts the resin to displace the calcium and magnesium ions in the raw water, forming softened water. The softened water is output through the central pipe 410 and the outlet of the resin tank 400, and is conveyed into the water outlet pipe 113 through the out-tank pipe 115 (as Figure 42 in the flowing direction indicated by arrow 1').

[0194] Another part of the raw water in the water inlet hole flows into the movable salt suction water distribution hole 165 through the fixed salt suction communication hole 176 and the salt suction communication cavity 135, and then flows into the bypass cavity 133 (as Figure 40 shown in Figure 41 the flowing direction indicated by arrow 2). The raw water in the bypass cavity 133 flows into the water outlet pipe 113 (as Figure 42 shown in the flowing direction indicated by arrow 2). In this way, the water in the water outlet pipe 113 is the mixed water of softened water and raw water. As Figure 41 shown. The rotation angle of the regulating valve core assembly 140 can be adjusted to regulate

[0195] as Figure 9 shown, the included angle between the fixed salt suction hole 175 and the fixed bypass cavity 133 is the mixed water angle. In the Figure 9 example, the mixed water angle is 35 degrees. Of course, the mixed water angle can also be other angles. As Figure 20 shown, when the valve core assembly 140 rotates from the service position to the salt suction position along the direction of the arrow, when the rotation angle is less than the mixed water angle, the movable salt suction water distribution hole 165 is communicated with the bypass cavity 133, and the movable salt suction water distribution hole 165 is not communicated with the salt suction cavity 134.

[0196] as Figures 13-15As shown, according to some embodiments of the present invention, the adapter assembly 200 also includes an adapter integrated seat 210, and the adapter integrated seat 210 is internally structured with a first flow path 2101, a second flow path 2102, a mixed salt flow path 2103, a backwash flow path 2104 and an adapter chamber 2105, and the outer peripheral side of the adapter integrated seat 210 corresponding to each flow path is provided with an adapter interface; one end of the first flow path 2101 is connected to the tank inlet pipe 114 through the corresponding adapter interface, and the other end of the first flow path 2101 is connected to the tank inlet pipe 114 through the corresponding adapter interface. The adapter is connected to the resin filling part 420 of the resin tank 400; 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, 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 adapter chamber 2105. The bottom of the adapter 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 adapter 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.

[0197] like Figure 1 and Figure 16 As shown, in the specific configuration, the adapter assembly 200 is connected to the resin tank 400 through the water channel assembly 300, that is, the water channel is guided into the resin tank 400 by the water channel assembly 300. In this embodiment, the first flow path 2101, the second flow path 2102, the salt mixing flow path 2103, and the backwash flow path 2104 are all flow channel structures constructed in the adapter integrated seat 210, and their respective flow paths are formed with respective ports on the outer peripheral end surface of the adapter integrated seat 210, and the respective ports are provided with adapters, and the connection with the soft water valve 100 and the water channel assembly 300 is achieved through the adapters. Among them, the two ends of the first flow path 2101 are respectively connected to the tank inlet pipe 114 and the water channel assembly 300 through the corresponding adapters arranged on the outer surface of the adapter integrated seat 210, so that the raw water can be introduced from the water inlet pipe 112 of the soft water valve 100 into the resin tank 400 filling part of the resin tank 400.

[0198] like Figure 13 , Figure 15As shown, the transfer chamber 2105 is a chamber constructed inside the transfer integrated base 210. The chamber of 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, and this port is connected to the water path assembly 300 or directly to the central pipe 410 of the resin tank 400, enabling the water path to be directly connected to the central pipe 410 inside the resin tank 400 from the transfer chamber 2105 to realize the flow of the reverse circulation water path. Specifically, one end of the second flow path 2102, one end of the mixed salt flow path 2103, and one end of the backwash flow path 2104 are all connected to the corresponding interfaces on the soft water valve 100 through the corresponding adapters, realizing the connection of different water paths on the soft water valve 100 to the transfer 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 transfer chamber 2105. The transfer chamber 2105 can realize the connection of multiple water paths to the central pipe 410 of the resin tank 400, so that when in the service position, the water path can flow out from the second flow path 2102 and finally realize the soft water supply through the water outlet pipe 113.

[0199] Among them, one end of the mixed salt flow path 2103 is connected to the valve chamber 111 of the soft water valve 100 through the jet pipe 181. The moving piece 160 and the fixed piece 170 in the valve chamber 111 can realize the water path switching, enabling the raw water to enter the mixed salt flow path 2103, and enabling the raw water to be mixed with the brine in the mixed salt flow path 2103 and enter the central pipe 410 of the resin tank 400. The brine entering the central pipe 410 can clean the resin particles to realize the regeneration of the resin particles.

[0200] One end of the backwash flow path 2104 is connected to the valve chamber 111 of the soft water valve 100 through the backwash pipe 182. The moving piece 160 and the fixed piece 170 in the valve chamber 111 can realize the water path switching, enabling the raw water to enter the backwash flow path 2104. The backwash flow path 2104 is connected to the central pipe 410 of the resin tank 400 through the transfer chamber 2105, enabling the raw water to enter from the central pipe 410 to perform a reverse flush on the resin particles to realize the regeneration of the resin particles.

[0201] It can be understood that through the construction of the transfer chamber 2105, multiple flow paths can be connected to the central pipe 410 of the resin tank 400 through one port of the transfer chamber 2105, reducing the number of ports for each flow path to be connected to the central pipe 410 of the resin tank 400, realizing the integration of multiple water paths, and reducing the overall space occupied by the water softener.

[0202] When specifically setting, such as Figure 13As shown, one end of the first flow path 2101, the second flow path 2102, the mixed salt flow path 2103 and the backwash flow path 2104 are extended in the same direction, wherein the first flow path 2101 and the second flow path 2102 are arranged side by side, and the mixed salt flow path 2103 and the backwash flow path 2104 are arranged side by side. It can be understood that one end of the first flow path 2101, the second flow path 2102, the mixed salt flow path 2103 and the backwash flow path 2104 are extended in the same direction, so that the soft water valve 100 and the adapter assembly 200 can be aligned once to achieve multiple flow paths to be aligned and connected, so as to simplify the flow path docking setting with the soft water valve 100 and facilitate disassembly and assembly. At the same time, the first flow path 2101 and the second flow path 2102 are arranged side by side, and the mixed salt 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.

[0203] like Figure 13 and Figure 29 As shown, according to some embodiments of the present invention, the adapter integrated seat 210 also has a salt absorption flow path 2106, one end of the salt absorption flow path 2106 is connected to the salt box 500, and the other end of the salt absorption flow path 2106 is connected to the mixed salt flow path 2103, and the salt absorption flow path 2106 and the mixed salt flow path 2103 are connected to the front end of the adapter chamber 2105. It can be understood that the salt absorption flow path 2106 is used to provide a certain concentration of brine to the mixed salt flow path 2103, and then mix it with the raw water of the mixed salt flow path 2103, so as to provide the required brine concentration for resin regeneration. When brine is needed for resin regeneration, the salt absorption flow path 2106 can effectively introduce brine into the mixed salt flow path 2103 to ensure full mixing and uniform distribution of brine. By connecting the salt absorption flow path 2106 with the mixed salt flow path 2103, the supply path of brine is simplified, and the convenience of operation and the efficiency of the device are improved.

[0204] like Figure 14 As shown, according to some embodiments of the present invention, the adapter assembly 200 further includes an ejector 240, which is arranged at the junction of the salt absorption flow path 2106 and the mixed salt flow path 2103, so that the ejector 240 can absorb the salt water into the mixed salt flow path 2103. It can be understood that by arranging the ejector 240 in the salt water flow path and the mixed salt flow path 2103, when the raw water passes through the mixed salt flow path 2103, the salt absorption power is provided for the salt absorption flow path 2106, so as to reduce the salt absorption power set for the salt absorption flow path 2106 alone, and simplify the overall structure of the water softening device. In addition, the ejector 240 can mix the salt water and raw water in the salt absorption flow path 2106 and the mixed salt flow path 2103, which can improve the uniformity and efficiency of the salt water mixing, thereby ensuring that the resin can be fully regenerated and improving the overall treatment effect.

[0205] According to some embodiments of the present invention, the sewage discharge path 2107 is disposed in the adapter integrated seat 210, and the sewage discharge path 2107 is connected to the resin filling part 420 of the resin tank 400 through the first flow path 2101. It can be understood that the sewage discharge path 2107 is connected to the resin filling part 420 of the resin tank 400 flowing from the first flow path 2101. Since the resin particles are treated in a backwash mode in this embodiment, that is, the resin particles are treated in a reverse circulation waterway, when the resin is cleaned and replaced, the sewage after the resin is cleaned or replaced will be discharged from the end of the resin tank 400 where the raw water enters the resin in normal soft water. The sewage discharge path 2107 is connected to the first flow channel 310, which can reduce the setting of the sewage outlet of the separate resin tank 400, simplify the overall structure and flow path setting of the soft water device, and facilitate the assembly between the soft water valve 100 and the resin tank 400 or the waterway assembly 300.

[0206] In specific settings, such as Figure 3 and Figure 14 As shown, 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, and the mating sealing end 2512 is located in the sewage path 2107. The extrusion end 2511 is suitable for causing the mating sealing end 2512 to move to open the sewage 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 the present embodiment, in the normal state, the driving block 1433 is not in contact with the extrusion end 2511. When sewage discharge operation is required, the driven gear 1431 rotates, thereby making the driving block 1433 abut against the extrusion end 2511 of the sewage discharge 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.

[0207] It can be understood that the sewage discharge lever 251 is arranged in the sewage discharge channel 2107. Under normal conditions, the sewage discharge lever 251 can close the sewage discharge channel, and the sewage discharge channel 2107 will be opened by driving the block 1433 when the sewage discharge channel 2107 needs to be opened. In this embodiment, the sewage discharge lever 251 can be a conventional sewage discharge lever 251. The conventional sewage discharge lever 251 includes a rod body, and one end of the rod body has a sealing head, that is, the above-mentioned mating sealing end 2512. When it does not need to be opened, the sealing head can block the sewage discharge channel 2107, and when it needs to be opened, the sewage discharge channel 2107 is opened by an external force. For the specific structure of the sewage discharge lever 251, those skilled in the art should know its specific structure, so it will not be further described here.

[0208] For example, in specific applications, the position on the driven gear 1431 with the driving block 1433 is configured as the salt absorption position and is controlled by the control system. That is, when the control system issues a signal for salt absorption, the driven gear 1431 can be rotated, and the driving block 1433 is brought into contact with the extrusion end 2511 of the sewage discharge lever 251 by rotation, thereby opening the sewage discharge channel 2107. When the sewage discharge channel 2107 does not need to be opened, the driven gear 1431 is rotated to displace the driving block 1433 from the extrusion end 2511 of the sewage discharge lever 251, and then the sewage discharge lever 251 can close the sewage discharge channel 2107 again.

[0209] It can be understood that in this embodiment, the sewage discharge channel 2107 is opened by arranging the driving block 1433 on the driven gear 1431. The overall structure is simple and efficient, and can quickly respond to open the sewage discharge channel 2107 quickly. And the sewage discharge channel 2107 is opened by mechanical transmission, which has higher reliability and anti-interference ability.

[0210] As Figure 3 shown, in specific settings, there can be multiple driving blocks 1433, and the driving blocks 1433 are arranged at intervals. In the overall product, sewage discharge is often required in multiple states. In this embodiment, multiple driving blocks 1433 are arranged on the driven gear 1431 to enable sewage discharge operations in different states, improving the applicability of the sewage discharge system in this example.

[0211] As Figure 3As shown, two driving blocks 1433 are provided on the driven gear 1431. The two driving blocks 1433 are located at different positions respectively. Through the distribution at different positions, the two driving blocks 1433 can respectively control the opening of the sewage discharge channel in at least two states. Of course, the number of driving blocks 1433 can also be three, four, etc. Generally, by different distribution positions, the driving blocks 1433 can correspond to different states. In the accompanying drawings of the specification of this application, only the case of two driving blocks 1433 is described.

[0212] In specific applications, the two driving blocks 1433 have the same structure and the same material. Of course, the two driving blocks 1433 can also have different structures. In some examples, the minimum distances between the multiple driving blocks 1433 and the extrusion end 2511 of the sewage discharge push rod 251 are approximately the same. Theoretically, the minimum distances between the multiple driving blocks 1433 and the push rod assembly are equal. However, due to processing and assembly and other relationships, there are often certain errors. Therefore, it is sufficient that the minimum distances are approximately the same. It can be understood that this minimum distance can reflect the depth of the action of the sewage discharge push rod 251. Generally, the sewage discharge push rod 251 has a fixed action depth to achieve complete sealing of the sewage discharge water path 2107. By limiting the equal minimum distances, the sewage discharge water path 2107 can be stably opened when it is opened, and it can be ensured that the opening is in a fully opened state, thereby improving the stability of its opening.

[0213] According to an embodiment provided by the present invention, as Figure 3 shown, a lever mechanism 270 is provided between the driving block 1433 and the sewage discharge push rod 251. The lever mechanism 270 is used to amplify and transmit the thrust. The driving block 1433 is arranged on the driven gear 1431. The driven gear 1431 is connected to the rotating shaft 150 to transmit mechanical energy, so that the moving piece 160 rotates to realize the water path switching. In this embodiment, the service life of the sewage discharge push rod 251 is improved by the setting of the lever mechanism 270, and the difficulty and cost of maintenance are reduced.

[0214] It can be understood that the driven gear 1431 meshes with the driving gear 1432 and is connected to the rotating shaft 150. The way that the driving block 1433 directly acts on the sewage pressure rod 251 will make the driving block 1433 vulnerable to damage. Especially in the case of long-term use, this problem is particularly prominent. Once the driving block 1433 is damaged, it is necessary to disassemble the driven gear 1431, and the disassembly of the driven gear 1431 is difficult and easily causes damage to the spool assembly 140 during the disassembly and assembly process. In this embodiment, by providing a lever mechanism 270 between the driving block 1433 and the sewage pressure rod 251 and transmitting through the intermediate lever mechanism 270, the damage of the driving block 1433 is greatly avoided, the service life of the driving block 1433 is extended, and compared with the disassembly and maintenance of the driven gear 1431, the disassembly of the lever mechanism 270 is more convenient, and the maintenance difficulty and cost are lower.

[0215] As Figure 14 shown Figure 29 In an embodiment provided by the present invention, the adapter assembly 200 further includes a salt suction check valve 260. The salt suction check valve 260 is disposed in the adapter cavity 2105 and is located at the end of the salt mixing flow path 2103. It can be understood that the salt suction check valve 260 can be a one-way valve, a check valve or a similar component, and 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 failures. At the same time, through the application of the salt suction check valve 260, the accuracy and continuity of the brine supply can be ensured, the requirements for resin regeneration can be met, and the overall treatment effect can be improved.

[0216] In a specific setting, 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 is communicated with the first flow path 2101 and realizes the connection between the first flow path 2101 and the resin filling part 420 in the resin tank 400. The second adapter 230 is communicated with the adapter cavity 2105 and realizes the connection between each flow path and the central pipe 410 in the resin tank 400. It can be understood that through the combined use of the first adapter 220 and the second adapter 230, the connection between the adapter cavity 2105 and the central pipe 410, and between the first flow channel 310 and the resin tank 400 can be conveniently realized, improving the flexibility and maintainability of the device.

[0217] As Figures 16-18As shown, according to an embodiment provided by the present invention, the waterway component 300 includes a main body portion 301. The main body portion 301 is connected to the resin tank 400. The main body portion 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. The second flow channel 320 has a second connection end 340 for fluid input or fluid output. The first flow path 2101 is connected to the resin filling portion 420 in the resin tank 400 through the first connection end 330. The transfer cavity 2105 is connected to the central pipe 410 in the resin tank 400 through the second connection end. The first flow channel 310 is provided with a first connection port 350 for separately communicating with the resin filling portion 420 of the resin tank 400. The first connection end 330 is fixedly connected to the first flow channel 310 and the two are in communication with each other. Among them, 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 pipe 410 of the resin tank 400. The second connection end 340 is fixedly connected to the second flow channel 320 and the two are in communication with each other. Among them, the second connection end 340 is used for fluid input or fluid output. In the design of the waterway component, it is necessary to satisfy the switching of five functional channels of water supply, backwashing, regeneration, water replenishment, and normal washing in the water softener. Therefore, usually, the waterway component integrates multiple flow channels to form an integral structure, which undoubtedly requires a complex molding die to construct multiple flow channels. In this embodiment, through two flow channels, namely the first flow channel 310 and the second flow channel 320, communication ports 164 are respectively provided on the two flow channel pipes, namely the first connection port 350 and the second connection port 360, as Figure 18 shown. The two connection ports can enable the two flow channels to be respectively connected to the resin filling portion 420 and the central pipe 410 in the resin tank 400. The central pipe 410 in the resin tank 400 is isolated from the resin filling portion 420 around the central pipe 410 through its own pipe wall. This enables the two connection ports to be respectively connected to different parts in the resin tank 400 and thus enables the switching of the flow direction in the resin tank 400.

[0218] In this embodiment, the first flow channel 310 and the second flow channel 320 are respectively used for the input or output of liquid fluid, and the determination of input or output is controlled and selected through the soft water valve 100 connected thereto. It can be understood that in the soft water valve 100, it is necessary to satisfy the softening water path during the soft water process, and it is also necessary to satisfy the regeneration path for the treatment of resin particles in the resin tank. For example, during softening, raw water enters the first flow channel 310 through the first connection port 350, is softened by the resin particles in the resin tank 400, and the treated water rises through the central pipe 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 the input of fluid, and the second connection port 360 is used for the output of fluid. During regeneration, brine enters the second flow channel 320 through the second connection port 360, enters the bottom of the resin tank 400 through the central pipe 410, and the brine entering the bottom can rise along the outer peripheral part of the resin tank 400 to clean the resin particles, then enters the first flow channel 310, and is output from the first connection port 350 in the first flow channel 310. At this time, the first connection port 350 is used for the output of fluid, and the second connection port 360 is used for the input of fluid.

[0219] It can be understood that in this embodiment, the switching between the soft water path and the regeneration water path is realized through two flow channels, which simplifies the structure of the number of flow channels, makes the overall structure simple, and reduces the preparation difficulty.

[0220] As Figure 16 shown, in specific settings, both the water path component 300 and the resin tank 400 are made of plastic material. The plastic material is easy to form, is conducive to the construction of flow channels and the construction of complex shapes, and the plastic material formed integrally can combine various plastics together, making the overall form a product with a compact structure and no seams.

[0221] In specific applications, as Figure 18 shown, the first connection port 350 is a truncated port, and the opening cross-section of the first connection port 350 in the cross-sectional direction of the resin tank 400 is less than or equal to the overlapping surface of the first flow channel 310 and the resin filling part 420 in the cross-section. The water path channel can realize the basic functions of the water softener through connection with the resin tank 400. That is, raw water can enter the resin tank 400 through the first flow channel 310 and flow forward to realize the softening function, and brine can also return from the first flow channel 310 to the mixed salt flow channel and enter the central pipe 410 to realize the reverse flow function, etc. In this embodiment, the first connection port 350 is opened along the extension direction of the first flow channel 310, as long as the opened truncated port does not exceed the corresponding range of the resin tank 400, which enables the size of the first connection port 350 to be unrestricted, and further enables the water distribution effect of the raw water through the first connection port 350 not to be affected by the opening size.

[0222] It can be understood that, as Figure 18 shown, in this embodiment, a part of the entity forming the first flow channel 310 straddles above the resin tank 400, which makes the first flow channel 310 and the resin tank 400 have an intersecting plane in the horizontal direction, and this intersecting plane is the above-mentioned cross-section. That is to say, a part of the entity structure of the first flow channel 310 is located inside the resin tank 400, and the outer peripheral part of the resin tank 400 is a resin filling part 420 filled with resin particles. The first connection port 350 can open an opening of any size on the entity part located inside the resin tank 400, so that it is not limited by the inner diameter of the first flow channel 310, and even on the first flow channel 310 with a smaller inner diameter size, it can open a larger size of the first connection port 350 along its own extension direction, so as to meet the high-quality water distribution effect.

[0223] Specifically, in this embodiment, since a part of the wall body forming the first flow channel 310 straddles above the resin tank 400 and the first connection port 350 is opened on the wall body above the resin tank 400, the part of the wall body facing the resin tank 400 side can be a notch structure. At this time, the size of the first connection port 350 is equal to the overlapping part of the wall body and the resin filling part 420 in the resin tank 400. This increases the contact area between the first connection 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 connection port 350, enabling the water body to fully contact with the resin, and further improving the softening efficiency and softening quality of the water body.

[0224] According to an embodiment provided by the present invention, a plurality of resin tanks 400 are connected to the main body part 301, and the plurality of resin tanks 400 are arranged at intervals side by side along the extension direction of the first flow channel 310 or the extension direction of the second flow channel 320. Both the first connection end 330 and the second connection end 340 are 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 treatment effect. In the related art, usually only one resin tank 400 is set due to the influence of the assembly method, etc. If one resin tank 400 wants to load more resin particles, it needs to have a larger volume, which makes the whole component occupy a large space in the width direction, thus making the overall structure complex and not conducive to installation. In this embodiment, the method of a plurality of resin tanks 400 can make it narrower in the width direction under the condition of having the same volume, which is conducive to the assembly of the component.

[0225] When specifically setting, as Figure 1 Figure 18As shown, in this embodiment, there are two resin tanks 400, and the two resin tanks 400 are arranged in parallel. When determining the number of resin tanks 400, usually the water treatment capacity requirements of the entire water circuit board and the design of the overall structural space occupation are considered. Therefore, in some specific designs, three, four or more resin tanks 400 can be selected. It can be understood that when the resin tanks 400 are increased, the flow channels will be arranged in the length direction accordingly to achieve the connection between the resin tanks 400 and the flow channels to form a water circuit. The accompanying drawings of the specification of the embodiment of the present application are specifically described only by taking the example of two resin tanks 400.

[0226] As Figure 17 shown, both the first flow channel 310 and the second flow channel 320 extend along a straight horizontal line direction. Correspondingly, the resin tanks 400 are arranged in parallel along the horizontal straight line direction. The fluids in the first flow channel 310 and the second flow channel 320 can both enter the resin tanks 400 for treatment, and then are output or input through the first connection end 330 and the second connection end 340 to achieve a positive circulation water flow direction or a reverse circulation water flow direction.

[0227] Specifically, as Figure 1 shown, quick insertion holes are provided on both the first connection end 330 and the second connection end 340, and quick insertion parts are provided in the quick insertion holes. Both the first connection end 330 and the second connection end 340 are connected to the adapter assembly 200 through the quick insertion parts. Usually, after the water softener is installed, it is in a relatively narrow space, which makes assembly and disassembly difficult. In this embodiment, the connection is achieved by using a quick insertion connection method, which is convenient for assembly and disassembly.

[0228] When specifically setting, there are various quick insertion connectors, such as quick connectors, quick rotary joints, quick clamp connectors, and compression joints commonly used in pipeline connections. In this embodiment, by providing an insertion hole at the mouth of the first connection end 330, providing a joint on the adapter assembly 200, and opening an annular slot on the joint, the joint is inserted into the mouth of the first connection end 330, and then a clamping piece is inserted into the insertion hole, and a part of the clamping piece is located in the annular slot, thereby realizing the quick insertion connection between the adapter assembly 200 and the connection port. In the working state, the clamping piece is located in the slot to achieve clamping, and when disassembly is required, the clamping piece is taken out to complete disassembly, which simplifies the entire assembly and disassembly process.

[0229] As Figure 16 With Figure 18As shown, according to an embodiment provided by the present invention, the resin tank 400 is integrally formed with the waterway assembly 300; the resin tank 400 includes a tank body and a cover body. The tank body has a receiving cavity and an installation opening communicating with the receiving cavity, and the cover body is covered on the installation opening to connect the cover body and the tank body. After the tank body of the resin tank 400 is integrally formed with the waterway assembly 300, the upper part of the tank body and the waterway assembly 300 are in an integral structure state. In order to facilitate the installation of the water distributor and the filling of resin particles, a cover body structure is provided, and the cover body structure can achieve the sealing of the resin tank 400.

[0230] The tank body is generally arranged in a hollow cylindrical shape, and a receiving cavity is formed inside the tank body. Among them, the receiving cavity is the main part of the resin tank 400 assembly and is used to store resin. According to application requirements, the design of the receiving cavity can have different shapes and sizes to adapt to different resin volumes and performance requirements, and no special limitation is made here.

[0231] It can be understood that the resin tank 400 assembly can include one or more tank bodies, and the tank bodies are arranged in parallel. For the convenience of installation, the installation openings of the tank bodies are aligned towards the same side.

[0232] In a specific application, a tank opening is provided on the end face of one end of the tank body. The tank opening end is integrally formed with the waterway assembly 300, and the tank opening is used to allow and control the fluid to flow in and out of the receiving cavity. The size and shape of the tank opening can be adjusted according to actual needs to optimize the flow performance of the resin. At the same time, a communication port 164 communicating with the tank opening is provided on the waterway plate or the pump body, so as to realize the waterway connection between the tank body and the waterway plate or the pump body; an installation opening is provided at the end of the tank body far from the waterway assembly 300. On the one hand, this 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 the water distributor. Bolt holes are provided on the outer peripheral edge of the end of the tank body where the installation opening is provided.

[0233] As Figure 18 As shown, the cover body is covered at the installation opening to block the installation opening to ensure the relative sealing performance of the receiving cavity. The cover body and the tank body are axially connected and fixed through connecting parts such as screws. It can be understood that during the use of the resin tank 400 assembly, due to the need for a certain pressure to push the internal softening flow path, when the tank opening is axially arranged or the receiving cavity is axially arranged, a spreading force will be formed between the cover body and the tank body when the resin tank 400 assembly works. In the case of unstable water pressure and the repeated action of the spreading force, the stable connection between the cover body and the tank body can be achieved through the connection of bolts.

[0234] 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. Through the transmission mechanism 141, on the one hand, it can control the valve core assembly 140 to perform the control of waterway switching. On the other hand, it can control the opening of the sewage discharge waterway 2107 in the adapter assembly 200 through the cooperation of the transmission mechanism 141 and the adapter assembly 200, thereby realizing the control of the entire waterway, simplifying the control logic, improving the control efficiency, reducing the setting of components, and reducing the failure rate of the waterway control assembly. Further, the sewage discharge control assembly 250 is a sewage discharge lever 251. The sewage discharge lever 251 realizes the opening of the sewage discharge waterway 2107 by squeezing the driving block 1433 on the driven gear 1431, which is achieved by mechanical transmission. The structure of the entire switch is simple, and the reliability and stability are strong.

[0235] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or equivalently replace some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
