[0036] The following describes a salt box and a water softener of the utility model with reference to the accompanying drawings. It should be pointed out that the water softener described in the second embodiment of the utility model is realized based on the salt box described in the first embodiment of the utility model.

[0037] Before introducing the salt box of the water softener of the utility model, the utility model first briefly introduces the working principle and working process of the water softener: the water softener mainly utilizes the resin tank to soften the tap water, and utilizes the salt box to regenerate the resin in the resin tank.

[0038] For the resin tank: The resin tank is filled with ion exchange resin, which contains a large amount of sodium ions (Na+). When hard water (containing a high concentration of calcium ions Ca2+ and magnesium ions Mg2+) flows through the resin tank, the sodium ions on the resin are exchanged with the calcium and magnesium ions in the water. The sodium ions are released into the water, while the calcium and magnesium ions are adsorbed onto the resin, thereby softening the water. Over time, the sodium ions on the resin will gradually be replaced by calcium and magnesium ions until the resin reaches a saturated state and can no longer soften the water. At this point, the resin needs to be regenerated.

[0039] For the salt box: During the regeneration process, the salt (sodium chloride NaCl) in the salt box dissolves in water to form brine. This brine is sent to the resin tank and contacts the saturated resin. The sodium ions in the brine are exchanged with the calcium and magnesium ions on the resin again, replacing the calcium and magnesium ions and restoring the sodium ions on the resin, so that the resin regains the ability to soften water.

[0040] During the regeneration process, the displaced calcium and magnesium ions flow out of the resin tank along with the brine, forming waste liquid containing higher concentrations of calcium and magnesium, which is then discharged.

[0041] Specifically, the working process of a water softener is as follows: Hard water enters the water softener and first flows through the resin tank to be softened through the ion exchange process. With use, the resin gradually becomes saturated and the softening effect decreases. When the softening effect no longer meets the demand, the regeneration process is started. The brine in the salt tank is sent to the resin tank for ion exchange to restore the softening capacity of the resin. The waste liquid generated during the regeneration process is discharged, and new softened water is produced at the same time. After the regeneration is completed, the water softener continues to provide softened water until the resin is saturated again, and then the above process is repeated.

[0042] like Figures 1 to 5 As shown, the salt box of a water softener according to the first embodiment of the utility model comprises a salt box body 1, a salt box liner 2 and an electric control component.

[0043] The salt box body 1 is formed with a salt storage space, and a mounting opening 11 is formed at the top of the salt box body 1. The salt box lining 2 includes a first lining portion 21 and a second lining portion 22, wherein the second lining portion 22 is located below the first lining portion 21, and the first lining portion 21 covers the mounting opening 11 and an electric control component of the salt box is mounted on its outer side; the second lining portion 22 extends into the salt storage space through the mounting opening 11.

[0044] According to the salt box of the water softener of the embodiment of the utility model, a salt box liner 2 is arranged on the salt box body 1. On the one hand, for the first lining portion 21 of the salt box liner 2, it can not only cover the installation port 11 of the salt box to ensure the sealing of the salt box, but it also has the function of installing the electronic control component, that is, it reserves sufficient installation space for the electronic control component, thereby ensuring the stable installation of the electronic control component; on the other hand, for the second lining portion 22, its main function is to improve the overall structural stability of the salt box, to ensure that the salt box will not be deformed or damaged when subjected to pressure and weight, thereby helping to ensure that the salt box maintains its structural integrity during long-term use, thereby ensuring the long-term stable operation of the water softener.

[0045] In summary, the salt box of the water softener proposed by the utility model utilizes the design structure of the upper and lower double-layer lining, which not only takes into account functionality, but also takes into account durability and convenience of maintenance. Through the above design, the salt box of the water softener can more effectively resist the influence of the external environment, extend its service life, and also facilitate users to perform daily maintenance and inspection.

[0046] like Figure 2 and Figure 5 As shown, according to some embodiments of the present invention, a salt inlet 12 communicating with the salt storage space is formed on the front side wall of the salt box body 1, and the salt inlet 12 is openably connected to the salt box cover 3.

[0047] like Figure 1 As shown, the inner lining plate 221 of the second inner lining portion 22 is surrounded by an opening, and the opening corresponds to and is connected to the salt inlet.

[0048] In this embodiment, the salt inlet 12 is arranged on the front side wall of the salt box body 1. When the salt box cover 3 opens the salt inlet 12, an hourglass-shaped salt inlet space can be formed between the salt box cover 3 and the salt inlet 12, thereby making it more convenient for users to add salt into the salt box, improving the user experience and making salt adding more convenient.

[0049] It can be understood that since a portion of the front side wall of the salt box body 1 is hollowed out to form the salt inlet 12, when the salt box body 1 is subjected to extrusion pressure from the left and right sides, the presence of the salt inlet 12 will cause the pressure bearing capacity and structural strength of the salt box body 1 to be weak, that is, the left and right side walls of the salt box body 1 can be easily bent or flattened due to the salt inlet 12 opened in the middle. Therefore, in order to further enhance the structural strength of the salt box body 1 on the left and right sides of the salt inlet 12 and the rear side of the salt box body 1, the second lining portion 22 is designed as two lining plates 221 on the left and right sides of the salt inlet 12 and one lining plate 221 on the rear side. It can be understood that the three lining plates 221 can help strengthen the structural strength and pressure bearing capacity of the salt box body 1 in the left and right directions and the front and rear directions. In this way, when the salt box body 1 is subjected to extrusion pressure from the left and right sides or the front and rear sides, the three lining plates 221 can help bear most of the extrusion force, thereby avoiding deformation or damage of the salt box body 1.

[0050] In addition, when adding salt to the salt box, the lining plate 221 can also act as a buffer to prevent salt particles from directly hitting the metal or plastic parts of the salt box, thereby reducing damage to these parts. At this time, the lining part can be made of wear-resistant and corrosion-resistant materials, which can maintain the integrity of the salt box under the action of salt and other chemicals and extend its service life.

[0051] like Figure 2 As shown, further, the bottom end of the salt box cover 3 is hinged to the bottom edge of the salt inlet 12, and two connecting plates 31 are respectively provided on the left and right sides of the salt box cover 3, at least one connecting plate 31 is slidably connected to the two side walls of the salt box body 1 through a slide groove structure, and the connecting plates 31 are clamped between the inner lining plate 221 and the side wall of the salt box body 1.

[0052] In this embodiment, the bottom end of the salt box cover 3 is connected to the bottom edge of the salt inlet 12 via a hinge structure, so that the salt box cover 3 can rotate smoothly when opening and closing, while also providing a certain degree of flexibility to accommodate possible installation errors. In addition, connecting plates 31 are provided on the left and right sides of the salt box cover 3, and these connecting plates 31 are slidably connected to the side walls of the salt box body 1 via a slide groove structure, thereby facilitating the salt box cover 3 to move along the slide groove when opening, providing a smooth and easy-to-operate opening method.

[0053] It can be understood that, since each connecting plate 31 is sandwiched between the inner lining plate 221 and the side wall of the salt box body 1, the sealing of the chute in the chute structure can be achieved, thereby effectively preventing the salt from leaking to the outside of the salt box through the chute structure during the addition or use process, keeping the inside of the salt box clean and dry, and also reducing maintenance work. That is, through the above-mentioned sealing design, it can be ensured that the salt box will not leak salt due to structural defects during normal use, which is crucial to maintaining the overall performance and efficiency of the water softener.

[0054] In summary, this design not only improves the sealing performance of the salt box, but also enhances its durability and user-friendliness. Users can be more assured when adding salt without worrying about accidental salt leakage, and it also simplifies the maintenance and cleaning of the salt box.

[0055] like Figure 2 As shown, in some embodiments of the present invention, a sliding groove 13 is provided on one of the side walls (particularly the left and right side walls) of the salt box body 1 and the connecting plate 31, and a sliding column 32 is provided on the other. It can be understood that no matter whether the sliding groove 13 is provided on the salt box body 1 or the connecting plate 31, the sliding groove 13 will be blocked and sealed by the lining part, thereby preventing salt from leaking out of the salt box through the sliding groove 13.

[0056] like Figure 2 As shown, in a specific embodiment of the present invention, two arc-shaped sliding grooves 13 are respectively provided on the left and right side walls of the salt box body 1, and correspondingly, two sliding columns 32 are respectively provided on the ends of the two connecting plates 31 away from the salt box cover 3.

[0057] In this embodiment, the sliding groove 13 can adapt to the movement trajectory of the salt box cover 3 when opening and closing. The arc groove can provide a smoother sliding path, reduce friction, and make the cover easier to open and close. In addition, the sliding column 32 on the connecting plate 31 cooperates with the arc sliding groove 13 on the salt box body 1, allowing the connecting plate 31 to slide in the sliding groove 13. At this time, the design of the sliding column 32 is to improve the stability of the structure and ensure that the connecting plate 31 will not fall out of the groove during the sliding process. In this way, the combination of the design of the arc sliding groove 13 and the sliding column 32 can achieve precise sliding cooperation, which helps to ensure the stability of the salt box cover 3 when opening and closing, and also reduces the wear that may be caused by unsmooth sliding.

[0058] In summary, this design simplifies the process of the user operating the salt box cover 3. The user only needs to slide the cover along the arc groove to easily open or close the salt box without additional strength or skills. It can be understood that this design not only improves the convenience of operation of the salt box, but also may extend the service life of the salt box by reducing wear and improving durability. At the same time, the precise sliding mechanism also helps to keep the inside of the salt box clean and prevent salt from leaking into the external environment.

[0059] like Figure 1 As shown, according to some embodiments of the utility model, a connecting beam 4 is further provided between the two lining plates 221 , and the connecting beam 4 , the two lining plates 221 and the first lining portion 21 together define an inlet, which is arranged opposite to the salt inlet 12 .

[0060] In this way, the connecting crossbeam 4 is located between the two inner lining plates 221, and cooperates with the inner lining plates 221 and the first inner lining portion 21 to form a strong structural frame, thereby dispersing pressure and improving the stability of the salt box when bearing external loads.

[0061] like Figure 5 As shown, further, a sealing stopper 41 is provided between the connecting crossbeam 4 and the bottom end of the salt box cover 3. In this way, the sealing stopper 41 can be used to prevent fine salt particles from entering the gap between the connecting crossbeam 4 and the salt box cover assembly when adding salt, thereby preventing the salt box cover 3 from being stuck.

[0062] like Figure 1 As shown, according to some embodiments of the utility model, the first lining portion 21 includes a first mounting portion 211 for closing the mounting opening 11 and a second mounting portion 212 located at the rear side of the first mounting portion 211, wherein the first mounting portion 211 is used to install electronic control components in the electronic control assembly, and the second mounting portion 212 is used to install the controller 9 in the electronic control assembly.

[0063] In this embodiment, the first lining portion 21 is divided into two parts: a first mounting portion 211 and a second mounting portion 212. This partition design allows different parts of the electric control assembly (such as electric control components and the controller 9) to be properly installed in the salt box, which may help optimize the layout of the electric control assembly and improve its working efficiency.

[0064] Among them, the first installation portion 211 is specifically used for installing the electronic control components in the electronic control assembly, which may mean that this area is designed to provide necessary electrical connection and protection to ensure the stability and safety of the components during operation.

[0065] The second mounting portion 212 is used to mount the controller 9 , so as to place the controller 9 at a location that is more convenient for user access and maintenance, and may also help with heat dissipation and signal transmission of the controller 9 .

[0066] It can be understood that this partitioned installation design makes the maintenance and upgrade of the electronic control assembly more convenient. Users can more easily access and replace various parts of the electronic control assembly without disassembling the entire salt box. In addition, by installing different parts of the electronic control assembly in different areas of the liner, the space occupation can be reduced, the space utilization inside the salt box can be optimized, and it may also help reduce electromagnetic interference and improve the reliability of the system.

[0067] like Figure 1 As shown, in some specific embodiments of the present utility model, at least one of a salt box lamp 5 , a salt level detection sensor 6 and a reed switch sensor 7 is installed on the first installation portion 211 .

[0068] For example, the salt box lamp 5 is interference-fitted into the inner lining hole on the first mounting portion 211 through the silicone piece on the salt box lamp 5. When the salt box cover 3 is opened, the salt box lamp 5 will light up; when the salt box cover 3 is closed, the lamp will go out. The salt level detection sensor 6 is fixed through the sensor fixing groove on the first mounting portion 211 to detect the salt level of the salt box. The reed switch sensor 7 is fixed through the two ribs on the first mounting portion 211 to determine whether the salt box cover 3 is opened or closed.

[0069] like Figure 2 As shown, in some specific embodiments of the present invention, a magnetic element 8 is further installed on the first installation portion 211 near the salt inlet 12, and correspondingly, a magnetic fitting suitable for cooperating with the magnetic element 8 is also installed on the top of the salt box cover 3.

[0070] In this way, the combination of the magnetic element 8 and the magnetically attracted fittings allows the salt box cover 3 to be easily attracted to the first mounting portion 211 by magnetic force, and the user only needs to approach to close the cover, which greatly simplifies the operation process. In addition, magnetic connectors usually have a long service life and are not easy to wear, which means that the opening and closing mechanism of the salt box cover 3 can still remain efficient and reliable in long-term use.

[0071] For example, two cylindrical magnets are respectively installed on the left and right sides of the first mounting portion 211 adjacent to the salt inlet 12 . The two cylindrical magnets are fixed in the circular magnet groove of the first mounting portion 211 by interference fit, and are used to absorb the salt box cover 3 to close the salt inlet 12 .

[0072] like Figure 1 As shown, according to some embodiments of the utility model, a mounting groove 213 is formed at the bottom end of the second mounting portion 212, and the bottom end of the controller 9 is fitted in the mounting groove 213; and a first clip 214 is provided at the top end of the second mounting portion 212, and a second clip 215 is provided at the top end of the controller 9, and the first clip 214 is engaged with the second clip 215.

[0073] In this embodiment, the mounting groove 213 formed at the bottom of the second mounting portion 212 provides a precise mounting position for the controller 9, ensuring that the controller 9 can be firmly placed at the predetermined position, which helps to maintain the stability of the controller 9 and reduce vibration. The snap-fit ​​design between the first snap-fit ​​member 214 at the top of the second mounting portion 212 and the second snap-fit ​​member 215 at the top of the controller 9 provides a fast and safe connection method. The snap-fit ​​mechanism simplifies the installation and removal process of the controller 9 and ensures the firmness of the connection. In this way, the dual fixing effect of the mounting groove 213 and the snap-fit ​​structure can ensure the installation stability of the controller 9.

[0074] like Figures 1 to 5 As shown, the water softener according to the second embodiment of the utility model includes the salt box of the water softener described in the first embodiment of the utility model.

[0075] The technical effect of the water dispenser according to the second embodiment of the utility model is similar to the technical effect of the salt box introduced in the first embodiment, and will not be repeated here.
