[0050] A water softener is a device used to soften water quality. It reduces the formation of water scale by removing hardness ions in water, such as calcium and magnesium. In related technologies, a bypass valve is usually used in a water softener to achieve the switching of multiple water paths to achieve different functional modes. However, the design of the bypass valve on the water softener is not reasonable enough, resulting in a lack of compactness in the structure of the water softener.

[0051] To solve this technical problem, the present invention proposes a water softener.

[0052] Please refer to Figures 1 to 13, in an embodiment of the present invention, the water softener includes a resin tank 10 and a bypass valve 20. The resin tank 10 is provided with a receiving cavity 11, a water inlet 111, a water outlet 112, and a bypass water path 12 connecting the water inlet 111 and the water outlet 112. The water inlet 111 and the water outlet 112 are respectively connected to the receiving cavity 11; the bypass valve 20 is movably arranged in the bypass water path 12 to switch between the soft water mode and the raw water mode; in the soft water mode, the bypass valve 20 blocks the connection between the water inlet 111 and the water outlet 112; in the raw water mode, the bypass valve 20 blocks the connection between the receiving cavity 11 and the water outlet 112 and conducts the connection between the water inlet 111 and the water outlet 112; thereby improving the compactness level of the water softener.

[0053] In the technical solution of the present invention, by using the movable installation of the bypass valve 20 in the bypass water path 12, the switching between the soft water mode and the raw water mode of the water softener is realized to meet the user's requirements for soft water and raw water; specifically, compared with the solution where the bypass valve 20 is arranged on the pipeline outside the resin tank 10, in the present invention, the water inlet 111, the water outlet 112, and the bypass water path 12 are directly arranged on the resin tank 10, and the bypass valve 20 is directly installed on the bypass water path 12 of the resin tank 10, which can make the overall structure more compact and improve the compactness level of the water softener; it is also beneficial to improve the installation convenience of the bypass valve 20, save the assembly steps, and shorten the working hours.

[0054] It should be noted that the water softener protected by the present invention includes, but is not limited to, central water softeners and end water softeners. Among them, the end water softener mainly provides soft water for local or individual water-using devices or water outlets, and is used to improve the water quality delivered to these water-using devices or water outlets, reduce the impact of hard water on the device structure, human body or clothes, and improve the comfort of local water use. Specifically, the water-using devices include, but are not limited to, water heaters, washing machines, or humidifiers, etc., and the water outlets include, but are not limited to, shower heads, faucets, etc. For example, the end water softener is used in the bathroom scenario, and can make the water output from the shower head be soft water to improve the user's water use comfort. For the convenience of description, the present invention will take the end water softener applied to the bathroom as an example for explanation.

[0055] Specifically, the receiving cavity 11 of the resin tank 10 is used to store resin particles. The receiving cavity 11 is also provided with a water inlet 114, and the water inlet 114 and the water outlet 112 are connected through the receiving cavity 11; the resin tank 10 is also provided with a water inlet water path 14. One end of the water inlet water path 14 is provided with a water inlet 111 connected to an external water source, and the other end is provided with a water passing port connected to the water inlet 114. In this way, the water inlet 111 is connected to the receiving cavity 11 through the connection between the water inlet water path 14 and the water inlet 114, and the water outlet 112 is directly connected to the receiving cavity 11.

[0056] The switching of the bypass valve 20 between the soft water mode and the raw water mode mainly depends on the movable installation of the bypass valve 20 in the bypass waterway 12. The movable installation of the bypass valve 20 specifically includes, but is not limited to, the rotation of the bypass valve 20 around its own axis, the translation along the extending direction of its axis, and the yaw of the bypass valve 20. Furthermore, in the soft water mode, since the bypass valve 20 can block the direct connection between the water inlet 111 and the water outlet 112 through the bypass waterway 12, the water inlet 111 is connected to the water outlet 112 through the accommodation chamber 11. The raw water enters the water inlet passage 14 through the water inlet 111, and enters the accommodation chamber 11 through the connection of the water passing port and the water inlet 114. When the raw water in the accommodation chamber 11 passes through the resin particles in the accommodation chamber 11, the hardness ions in the water are adsorbed by the resin particles, and at the same time, sodium ions are released, thereby reducing the hardness of the water and forming the treated soft water. The soft water flows out of the resin tank 10 through the water outlet 112 to meet the soft water demand of the user.

[0057] In the raw water mode, since the bypass valve 20 blocks the connection between the accommodation chamber 11 and the water outlet 112 and conducts the connection between the water inlet 111 and the water outlet 112, the raw water enters the water inlet passage 14 and the bypass waterway 12 through the water inlet 111 and flows towards the water outlet 112 through the conduction of the bypass valve 20, thereby meeting the raw water demand of the user. Specifically, the raw water is an untreated external water source, which can specifically be tap water.

[0058] Please refer to Figures 1 to 5, in an embodiment of the present invention, a communication port 113 is provided on the cavity wall of the accommodation cavity 11 corresponding to the water outlet 112. The bypass valve 20 is rotatably arranged in the bypass water path 12. The bypass valve 20 is provided with a sealing portion 201 and a communication portion 202 distributed in its circumferential direction. The communication portion 202 is provided with a communication channel 203. In the soft water mode, the sealing portion 201 blocks the water inlet 111, and the communication channel 203 connects the communication port 113 and the water outlet 112. In the raw water mode, the sealing portion 201 blocks the communication port 113, and the communication channel 203 connects the water inlet 111 and the water outlet 112. It can be understood that the water outlet 112 can be connected to the accommodation cavity 11 through the communication port 113, and this communication port 113 can be connected to the bypass water path 12. Furthermore, through the rotational movement of the bypass valve 20 around its own axis in the bypass water path 12, the sealing portion 201 on the bypass valve 20 can selectively block the water inlet 111 or the communication port 113, and the communication portion 202 can selectively connect the water inlet 111 and the water outlet 112, or connect the communication port 113 and the water outlet 112. That is, in the soft water mode, it is necessary to connect the water inlet 111 and the water outlet 112 through the accommodation cavity 11. At this time, the sealing portion 201 blocks the water inlet 111, blocking the connection between the water inlet 111 and the water outlet 112 through the bypass water path 12, and the communication portion 202 connects the communication port 113 and the water outlet 112 through the communication channel 203, ensuring that after the water flows through the water inlet 111 into the resin tank 10, it also needs to flow through the resin particles in the accommodation cavity 11 for softening treatment, and then flows to the water outlet 112 through the communication port 113. In the raw water mode, it is necessary to connect the water inlet 111 and the water outlet 112 through the bypass water path 12. At this time, the sealing portion 201 blocks the communication port 113, blocking the connection between the water inlet 111 and the water outlet 112 through the accommodation cavity 11, and the communication portion 202 connects the water inlet 111 and the water outlet 112 through the communication channel 203, ensuring that after the water flows through the water inlet 111 into the resin tank 10, it directly flows to the water outlet 112 through the bypass water path 12, that is, the water does not undergo softening treatment.

[0059] Optionally, in an embodiment of the present invention, there is one sealing portion 201, and the soft water mode and the raw water mode share the same sealing portion 201, which helps to simplify the structure of the bypass valve 20, thereby reducing the switching difficulty and saving manufacturing and assembly costs. Among them, the sealing portion 201 and the communication portion 202 are arranged at intervals and selectively block the water inlet 111 or the communication port 113 in different modes. However, this design is not limited thereto. In other embodiments, there are two sealing portions 201, and the two sealing portions 201 are arranged on both sides of the communication portion 202 and respectively correspond to the water inlet 111 and the communication port 113.

[0060] Please refer to Figure 5 , Figures 8 to 9, in the embodiment of the present invention, the communication channel 203 includes a first channel 2031 and a second channel 2032 connected to the middle of the first channel 2031. The first channel 2031 penetrates through opposite sides of the communication part 202. The sealing part 201 and the second channel 2032 are respectively arranged on both sides of the first channel 2031. It can be understood that the communication channel 203 is composed of the first channel 2031 and the second channel 2032. Since the second channel 2032 is connected to the middle of the first channel 2031, the first channel 2031 and the second channel 2032 are perpendicular to each other, and the communication channel 203 is in a T shape. In this way, the structural stability of the bypass valve 20 can be ensured, and it is easy to process and manufacture. Also, since the first channel 2031 and the second channel 2032 are straight channels, the generation of eddy currents and turbulences caused by the complex shape of the communication channel 203 can be avoided, so that the resistance of the water flow when passing through the bypass valve 20 is small, the energy loss is reduced, and the bypass valve 20 can more efficiently connect the water outlet 112 with the circulation port 113 or the water inlet 111. Among them, the connection part of the first channel 2031 and the second channel 2032 can be arranged on the rotation axis of the bypass valve 20. Combining with the second channel 2032 being connected to the middle of the first channel 2031, the distances from the connection part of the first channel 2031 and the second channel 2032 to both ends of the first channel 2031 are equal, and are also equal to the distance from the connection part of the first channel 2031 and the second channel 2032 to the end of the second channel 2032 far from the first channel 2031. This can not only reasonably guide the direction of the water flow, but also ensure the uniformity of the structure and the water flow, improve the structural stability of the bypass valve 20, and extend the service life of the bypass valve 20.

[0061] Thanks to the T-shaped communication channel 203, only one sealing part 201 can be provided, and it is arranged on both sides of the first channel 2031 respectively with the second channel 2032. Further, in different modes, when the bypass valve 20 is rotated and the air outlet selectively communicates with the water inlet 111 or the circulation port 113, the sealing part 201 blocks the circulation port 113 or the water inlet 111, effectively blocking the communication between the circulation port 113 or the water inlet 111 and the air outlet. However, this design is not limited to this. In other embodiments, the communication channel 203 includes a first channel 2031 and a second channel 2032 that are connected in a V shape.

[0062] Specifically, in the embodiment of the present invention, the bypass waterway 12 is provided with a rotating cavity 13, and the bypass valve 20 is rotatably arranged in the rotating cavity 13; the cavity wall of the rotating cavity 13 is provided with a first through hole 131, a second through hole 132 and a third through hole 133. The first through hole 131 communicates with the circulation port 113, the second through hole 132 communicates with the water outlet 112, and the third through hole 133 communicates with the water inlet 111. The first through hole 131 and the third through hole 133 are respectively arranged on opposite sides of the rotation axis of the bypass valve 20, and the second through hole 132 is located between the first through hole 131 and the third through hole 133. It can be understood that because the second through hole 132 is arranged at intervals between the first through hole 131 and the third through hole 133, and the first through hole 131 and the second through hole 132 are respectively arranged on opposite sides of the rotation axis of the bypass valve 20, at this time, the first through hole 131, the second through hole 132 and the third through hole 133 are distributed in a triangle and respectively communicate with the circulation port 113, the water outlet 112 and the water inlet 111. When the sealing portion 201 does not block any one of the first through hole 131, the second through hole 132 and the third through hole 133, combined with the T-shaped design of the communication hole 203, the circulation port 113, the water outlet 112 and the water inlet 111 are mutually conducted through the communication hole 203;

[0063] Therefore, in the soft water mode, the bypass valve 20 is rotated by a certain angle so that the second channel 2032 is docked with the first through hole 131 and the first channel 2031 is docked with the second through hole 132. At this time, the sealing portion 201 blocks the third through hole 133, and the water flow in the accommodating cavity 11 sequentially flows through the circulation port 113, the first through hole 131, the second channel 2032, the first channel 2031, the second through hole 132 and flows out from the water outlet 112; in the raw water mode, the bypass valve 20 is rotated by a certain angle so that the second channel 2032 is docked with the third through hole 133 and the first channel 2031 is docked with the second through hole 132. At this time, the sealing portion 201 blocks the first through hole 131, and the water flow enters the resin tank 10 from the water inlet 111 and sequentially flows through the third through hole 133, the second channel 2032, the first channel 2031, the second through hole 132 and flows out from the water outlet 112. Because the first through hole 131 and the third through hole 133 are respectively arranged on opposite sides of the rotation axis of the bypass valve 20, during the process of switching between the soft water mode and the raw water mode, the bypass valve 20 can rotate 180° forward and backward to ensure the docking of the second channel 2032 with the first through hole 131 or the third through hole 133. In addition, an identification can be set on either the resin tank 10 or the bypass valve 20, and this identification can be used to remind the user of the conduction situation of the bypass valve 20. For example, an indication arrow is set on the bypass valve 20, and the arrow can correspondingly point to the circulation port 113 or the water inlet 111.

[0064] Please refer to Figure 6, in an embodiment of the present invention, the bypass valve 20 includes a bypass rotating shaft 21 and a gasket 22 provided on the bypass rotating shaft 21. The communication hole 203 is provided on the bypass rotating shaft 21, and the sealing portion 201 is provided on the gasket 22. The gasket 22 can be configured as a sealing structure with deformable properties such as a rubber gasket or a silicone gasket. Furthermore, by utilizing the deformability of the gasket 22, the third through hole 133 communicating with the water inlet 111 can be reliably sealed in the soft water mode, and the first through hole 131 communicating with the flow port 113 can be reliably sealed in the raw water mode. At the same time, the smooth rotation of the bypass rotating shaft 21 in the bypass water path 12, specifically in the rotation cavity 13, can be ensured. Among them, the sealing portion 201 and the communication portion 202 are distributed in the circumferential direction of the bypass rotating shaft 21, and the first hole 2031 of the communication hole 203 penetrates through the opposite sides of the bypass rotating shaft 21. One end of the second hole 2032 communicates with the second hole 2032, and the other end penetrates through the bypass rotating shaft 21 to be disposed on both sides of the first hole 2031 with the gasket 22; the installation method of the gasket 22 on the upper end of the bypass rotating shaft 21 includes but is not limited to bonding, clamping, and embedded connection.

[0065] Please refer to Figures 11 to 12 , in an embodiment of the present invention, the gasket 22 includes a gasket body 221 and a sealing lip 222. The gasket body 221 is provided with a sealing surface 2212 on the end face away from the bypass rotating shaft 21. The sealing surface 2212 can cover the water inlet 111 or the flow port 113. The sealing lip 222 is annularly provided on the outer periphery of the sealing surface 2212. The sealing portion 201 includes the sealing surface 2212 and the sealing lip 222. It can be understood that the sealing surface 2212 can be attached to the edge of the through hole communicating with the water inlet 111 or the flow port 113 to play a covering role, and when no pressure is applied to the sealing surface 2212, it can play a sealing role to a certain extent; the sealing lip 222 is connected to the gasket body 221 and can be fixed into a whole by integral molding, bonding, etc. Among them, the sealing lip 222 surrounds the outer periphery of the sealing surface 2212 and protrudes from the sealing surface 2212. When the sealing surface 2212 covers the water inlet 111 or the flow port 113, the sealing lip 222 is in interference contact with the wall surface where the through hole corresponding to the water inlet 111 or the flow port 113 is located, realizing the sealing of the water inlet 111 or the flow port 113. On the one hand, compared with the entire sealing surface 2212 protruding, the contact between the sealing lip 222 and the wall surface of the through hole can be changed into line-plane contact, and the contact area is small. On the basis of ensuring the sealing effect, the resistance received by the bypass valve 20 during rotation is small, which can effectively improve the rotation smoothness of the bypass valve 20, and thus improve the switching efficiency between the soft water mode and the raw water mode; on the other hand, the sealing lip 222 is annular, and the shape of its contour line can be circular, rectangular, polygonal, such as Figure 11As shown, the shape of the sealing lip 222 is hexagonal. Without affecting the smooth rotation of the bypass valve 20, the sealing effect can be enhanced by increasing the contact area between the sealing lip 222 and the wall surface where the through hole is located.

[0066] Furthermore, in the embodiment of the present invention, a deformation cavity 2211 is recessed on the end surface of the gasket body 221 close to the bypass rotating shaft 21. The sealing surface 2212 and the sealing lip 222 are arranged on the bottom wall of the deformation cavity 2211. In this way, when the bypass rotating shaft 21 rotates, the sealing lip 222 can reversely press against the gasket body 221, causing the deformation cavity 2211 to deform, further reducing the effective contact area between the sealing lip 222 and the wall surface where the through hole is located, thereby further reducing the frictional force received when the bypass valve 20 rotates, improving the rotation smoothness of the bypass valve 20, and improving the switching efficiency of different modes.

[0067] Optionally, in the embodiment of the present invention, the bypass rotating shaft 21 is provided with a mounting groove 211, and at least part of the sealing gasket 22 is received in the mounting groove 211. It can be understood that the end surface of the sealing gasket 22 provided with the opening of the deformation cavity 2211 is connected to the bottom of the mounting groove 211, which can make the bottom of the mounting groove 211 be part of the cavity wall of the deformation cavity 2211. By receiving at least part of the sealing gasket 22 in the mounting groove 211, a deformation space can be provided for the deformation of the gasket body 221, and the part protruding from the mounting groove 211 can play a role in sealing the water inlet 111 or the circulation port 113. Furthermore, when the bypass rotating shaft 21 rotates, the part of the sealing gasket 22 protruding from the mounting groove 211 is compressed into the mounting groove 211, which can reduce the effective contact area between the sealing gasket 22 and the resin tank 10, thereby improving the rotation smoothness of the bypass valve 20.

[0068] Please refer to Figures 6 to 7 , in the embodiment of the present invention, the bypass valve 20 further includes a bypass knob 23 exposed outside the resin tank 10. One end of the bypass rotating shaft 21 extending outward is connected to the bypass knob 23. With this setting, it is convenient for the user to directly act on the bypass knob 23 to drive the bypass rotating shaft 21 to rotate, realizing the switching between the soft water mode and the raw water mode. Among them, the bypass rotating shaft 21 can be integrally placed inside the resin tank 10, or can partially extend out of the resin tank 10. The connection method between the bypass knob 23 and the bypass rotating shaft 21 includes but is not limited to detachable connections such as snap connection and plug-in fit that are convenient for the processing and manufacturing of the bypass valve 20, and non-detachable connections such as welding and bonding that reduce the number of parts and save the assembly steps. The bypass valve 20 is manually driven to realize the switching between the soft water mode and the raw water mode. Or, in other embodiments, the bypass valve 20 can be electrically driven to realize the switching between the soft water mode and the raw water mode.

[0069] Optionally, in an embodiment of the present invention, the bypass rotating shaft 21 is provided with a fixing hole 212. The bypass knob 23 includes a connected holding portion 231 and a mounting portion 232. The holding portion 231 is exposed outside the fixing hole 212, and the mounting portion 232 is inserted and installed in the fixing hole 212. It can be understood that the fixing hole 212 on the bypass rotating shaft 21 is provided at one end of the bypass rotating shaft 21 facing the bypass knob 23 and is not communicated with the communication hole 203. Inserting the mounting portion 232 of the bypass knob 23 into the fixing hole 212 can achieve the rapid assembly of the bypass rotating shaft 21 and the bypass knob 23; while the holding portion 231 is exposed outside the fixing hole 212, it can protrude from the resin tank 10 and thus serve as the driving part of the bypass valve 20, facilitating the user to apply force to the bypass knob 23 through the holding portion 231 to drive the bypass rotating shaft 21 to rotate in the bypass water passage 12. Wherein, the holding portion 231 and the mounting portion 232 can be formed into an integral part by integral molding, welding, etc., or can also be fixed into a whole by means such as snap connection and screw fixation.

[0070] Please refer to Figure 6 and Figure 8 , in an embodiment of the present invention, the hole wall of the fixing hole 212 is provided with a clamping hole 213. The mounting portion 232 includes a connecting clamping protrusion 2321 that cooperates with the clamping hole 213. In this way, after the mounting portion 232 of the bypass knob 23 is inserted into the fixing hole 212, it is further fixed by the clamping cooperation between the connecting clamping protrusion 2321 and the clamping hole 213, effectively reducing the possibility of the bypass knob 23 disengaging from the bypass rotating shaft 21, improving the connection reliability between the bypass knob 23 and the bypass rotating shaft 21, and also preventing the bypass knob 23 from rotating relative to the bypass rotating shaft 21, improving the driving efficiency of the bypass valve 20. Specifically, clamping holes 213 are respectively provided on opposite sides of the hole wall of the fixing hole 212, and two connecting clamping protrusions 2321 are provided corresponding to the two clamping holes 213, effectively strengthening the connection strength between the bypass knob 23 and the bypass rotating shaft 21.

[0071] Please refer to Figure 6 and Figure 10, in an embodiment of the present invention, the mounting portion 232 includes a limiting rib 2322. Two support ribs 214 are provided at intervals in the fixing hole 212. The two support ribs 214 respectively abut against opposite side surfaces of the limiting rib 2322 to restrict the rotational movement of the mounting portion 232 in the fixing hole 212. Specifically, the support ribs 214 extend from the bottom of the hole towards the outside of the fixing hole 212, and the support ribs 214 can also be connected to the hole wall of the fixing hole 212, which can enhance the structural stability of the fixing hole 212. Among them, two support ribs 214 are provided at intervals, so that a guiding channel for guiding the insertion of the limiting rib 2322 can be formed between the two support ribs 214. And when the opposite side surfaces of the limiting rib 2322 abut against the two side support ribs 214, the connecting convex 2321 is installed into the card hole 213, realizing the rapid assembly of the bypass knob 23 on the bypass rotating shaft 21; and the opposite side surfaces of the limiting rib 2322 respectively abut against the two support ribs 214, increasing the contact area between the mounting portion 232 and the bypass rotating shaft 21, thereby restricting the rotation of the limiting rib 2322 in the fixing hole 212, which can not only reduce the possibility of the separation of the connecting convex 2321 from the card hole 213, but also improve the connection stability of the bypass knob 23 in the fixing hole 212. However, this design is not limited thereto. In other embodiments, a support guiding rib is provided on the hole wall of the fixing hole 212 corresponding to the card hole 213. The support guiding rib is used to guide the connecting convex 2321 to move to the card hole 213, and can also increase the contact area between the mounting portion 232 and the bypass rotating shaft 21 to a certain extent.

[0072] Further, the limiting rib 2322 is connected to the connecting convex 2321 through a connecting rib 2323. The support rib 214 is provided with an avoidance groove 2141 for avoiding the connecting rib 2323. In this way, by connecting the limiting rib 2322 and the connecting convex 2321 through the connecting rib 2323, the overall structural strength and rigidity of the bypass knob 23 can be enhanced, ensuring the connection between the bypass knob 23 and the bypass rotating shaft 21; and by providing the avoidance groove 2141 on the support rib 214, it not only does not affect the assembly of the bypass knob 23, but also can play a role in positioning and guiding to a certain extent, ensuring that the limiting rib 2322 can be accurately arranged within the two support ribs 214 and the connecting convex 2321 is clamped in the card hole 213. However, this design is not limited thereto. In other embodiments, the support rib 214 is not provided with an avoidance groove 2141.

[0073] Please refer to Figure 1 and Figure 13, in an embodiment of the present invention, the water softener further includes an installation clamp 30. The resin tank 10 is provided with a through hole 134 for the installation clamp 30 to pass through. The bypass rotating shaft 21 is provided with a clamp ring groove 215. The installation clamp 30 passes through the through hole 134 and is limited in the clamp ring groove 215. It can be understood that the bypass water passage 12 is provided with a rotating cavity 13. The rotating cavity 13 is provided with an opening for the bypass valve 20 to extend into. The bypass rotating shaft 21 of the bypass valve 20 is inserted into the opening and rotatably installed in the rotating cavity 13. The through hole 134 is formed on the cavity wall of the rotating cavity 13 and is arranged near the outer edge of the opening. Among them, the through hole 134 includes a first hole part and a second hole part. The installation clamp 30 includes a connecting section and two limiting sections laterally connected to the same side of the connecting section. The connecting section is provided with a limiting hook that is clamped and matched with the first hole part. The second hole part penetrates through the opposite sides of the rotating cavity 13 and is used for the limiting sections to pass through. Specifically, when the bypass rotating shaft 21 is inserted into the opening, the clamp ring groove 215 corresponds to the through hole 134. When the installation clamp 30 is assembled to the resin tank 10, the limiting hook is clamped in the first hole part and at least partially limited in the clamp ring groove 215. While the limiting sections pass through the second hole part, part of the limiting sections are installed in the clamp ring groove 215. In this way, because the bypass rotating shaft 21 is rotatably installed in the rotating cavity 13, the installation of the installation clamp 30 will not affect the rotation of the bypass rotating shaft 21 around its own axis. At this time, the clamp ring groove 215 plays a role in avoiding the installation clamp 30, and can also effectively prevent the bypass rotating shaft 21 from disengaging from the rotating cavity 13 through the opening. At this time, the clamp ring groove 215 cooperates with the installation clamp 30 to play a limiting role, thereby reliably improving the installation reliability of the bypass valve 20 on the resin tank 10. However, this design is not limited to this. In other embodiments, the cavity wall of the rotating cavity 13 is provided with an elastic limiting member that can be clamped into the clamp ring groove 215.

[0074] Please refer to Figures 6 to 8 , in an embodiment of the present invention, the bypass water passage 12 is provided with a rotating cavity 13 for installing the bypass rotating shaft 21. The bypass rotating shaft 21 is further provided with a sealing ring groove 216. The sealing ring 40 is embedded in the sealing ring groove 216, and the side away from the sealing ring groove 216 abuts against the cavity wall of the rotating cavity 13. In this way, it effectively prevents water from flowing out of the resin tank 10 through the gap between the bypass rotating shaft 21 and the rotating cavity 13 through the opening of the rotating cavity 13, reducing the waste of water resources.

[0075] Specifically, the sealing ring groove 216 and the clamp ring groove 215 are arranged at intervals along the axial extension direction of the bypass rotating shaft 21. The sealing ring groove 216 is arranged close to the communicating part 202 of the bypass rotating shaft 21 to block the flow of water. At the same time, it effectively prevents water from flowing out of the resin tank 10 through the through hole 134. Similarly, the clamping hole 213 for the connecting clamping protrusion 2321 to be clamped and matched is also arranged on the side of the sealing ring groove 216 away from the communicating part 202. At this time, as Figure 8As shown, the card hole 213 can be provided between the sealing ring groove 216 and the clamp ring groove 215. Of course, in other embodiments, the card hole 213 can be provided on the side of the clamp ring groove 215 away from the sealing ring groove 216.

[0076] Please refer to Figures 1 to 4 , in the embodiment of the present invention, the water inlet 111, the water outlet 112 and the bypass water path 12 are provided at the bottom of the resin tank 10. In this way, the water inlet path 14 extends from the bottom of the resin tank 10 towards its top, forming a water passing port. The water inlet 114 and the water passing port are arranged at the top of the resin tank 10, so that water can enter from the water inlet 114, and by relying on its gravity, it can flow over the resin particles from top to bottom. The softened water formed flows out from the water outlet 112 at the bottom, reducing additional power equipment and simplifying the complexity of the entire system. Furthermore, the risk of shutdown caused by power equipment failure is reduced, and the reliability of the water softener during use is improved.

[0077] The arrangement that the water inlet path 14 extends from bottom to top can make the impact force of the water flow gradually weaken as it flows upward when entering the water inlet path 14, which helps to reduce the impact force on the resin tank 10 and reduce the risk of deformation or damage caused by water flow impact, enhancing the stability and service life of the resin tank 10; and the water flow flows over the resin particles by relying on gravity, the water flow is relatively stable, with small resistance and no excessive turbulence and pressure fluctuations. Compared with the water flow directly impacting the resin particles, it effectively reduces the impact force of the water flow on the resin particles, reduces the risk of resin particle breakage, and extends the service life of the resin particles. That is to say, the resin tank 10 requires less maintenance and replacement during use, can reduce the operating cost, and at the same time reduce the shutdown time caused by resin particle replacement, which helps to improve the overall operating efficiency of the water softener

[0078] In addition, the water inlet 111, the water outlet 112 and the bypass water path 12 are all arranged at the bottom of the resin tank 10, which can make the components such as relevant pipes and valves be centrally arranged, reduce the crossing and detouring of the pipes, and further reduce the space requirement around the resin tank 10, facilitating the water softener to better adapt to the site conditions with limited space, improving the space utilization rate, and at the same time facilitating the workers to quickly locate and maintain the water inlet 111 and the water outlet 112, improving the disassembly and assembly efficiency; it can also shorten the bypass water path 12, thereby shortening the water outlet time of the raw water, and when manually switching between the raw water mode and the softened water mode, it is convenient for the user to rotate and drive the bypass valve 20.

[0079] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural transformations made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
