[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] Currently, water softening and purifying equipment has functions of softening, purifying, and heating water, resulting in a large number of components and a relatively large size. In related technologies, by rationally designing the installation positions of multiple components, they are compactly installed within the casing of the water softening and purifying equipment. The casing is the outermost component of the equipment, and the brine tank door is also located on the outermost side. The door and casing together form the external shape of the water softening and purifying equipment. Because the sizes of the casing and door are already designed, it is difficult to design the brine tank to be larger. For example, if the volume of the brine tank is increased, the door 033 cannot be properly connected to the brine tank.

[0035] To resolve the above technical issues, please refer to Figures 1 to 3 This application proposes a salt tank assembly 030, which includes a movable mounting member 031, a tank body 032, and a door 033. The movable mounting member 031 is used to connect with an external component 12. The tank body 032 has a salt-containing cavity 0321 and a salt inlet 0322 communicating with the salt-containing cavity 0321. The tank body 032 includes a first side plate 0323 and a second side plate 0324 arranged at relatively intervals. The first side plate 0323 is provided with a through hole 032a for the movable mounting member 031 to be inserted into the salt-containing cavity 0321. The door 033 is movably connected to the movable mounting member 031 and the second side plate 0324 so that the door 033 can open and close the salt inlet 0322.

[0036] It should be noted that the external component 12 is a component that can provide stable support for the movable mounting part 031. For example, the external component 12 can be a shell located on the side of the housing 032. The movable mounting part 031 can be connected to the side of the shell facing the housing 032. After the movable mounting part 031 is connected to the external component 12, the movable mounting part 031 can provide a movable mounting position.

[0037] The shape of the box 032 can be a cuboid, a cylinder, etc., and the box 032 can be set on the side of the external component 12. The inside of the box 032 can have a salt-containing chamber 0321, and the top of the box 032 can have a salt inlet 0322 communicating with the salt-containing chamber 0321. Salt particles can be stored in the salt-containing chamber 0321. When the resin tank of the water softening system needs to be replenished with salt, the salt particles in the salt-containing chamber 0321 can be drawn into the resin tank, so that the resin tank can continuously soften water. After the salt particles in the salt-containing chamber 0321 are used up, salt particles can be replenished into the salt-containing chamber 0321 through the salt inlet 0322.

[0038] The housing 032 includes a first side plate 0323 and a second side plate 0324 that are spaced apart from each other. The first side plate 0323 and the second side plate 0324 can be the top of the housing 032, and a salt-containing cavity 0321 can be formed between the first side plate 0323 and the second side plate 0324. In addition, the first side plate 0323 has a first side edge, and the second side plate 0324 has a second side edge. The first side edge and the second side edge are arranged opposite to each other and can define a salt inlet 0322. The first side plate 0323 is located on the side of the housing 032 facing the external component 12. The first side plate 0323 has a through hole 032a, which allows the movable mounting member 031 to be inserted into the salt-containing cavity 0321 through the through hole 032a, so that the movable mounting member 031 can be located between the first side plate 0323 and the second side plate 0324.

[0039] The door 033 can be movably connected to the movable mounting part 031 and the second side plate 0324, allowing the door 033 to open and close the salt inlet 0322 normally. More specifically, when it is necessary to add salt to the salt chamber 0321, the door 033 can be opened to open the salt inlet 0322. After the salt has been added, the door 033 can be closed to close the salt inlet 0322, making it very convenient to add salt. Since the movable mounting part 031 is located between the first side plate 0323 and the second side plate 0324, and the door 033 is located between the movable mounting part 031 and the second side plate 0324, the distance between the first side plate 0323 and the second side plate 0324 can be larger than the width of the door 033. Therefore, without changing the size of the door 033, the volume of the box 032 can be increased, allowing it to hold more salt.

[0040] Please see Figures 1 to 3 In some embodiments, the movable mounting member 031 has a first connecting part 0311, which passes through the through hole 032a. The second side plate 0324 has a second connecting part 032b. The opposite sides of the door body 033 are slidably engaged with the first connecting part 0311 and the second connecting part 032b, respectively, so that the door body 033 can move between opening the salt inlet 0322 and closing the salt inlet 0322.

[0041] Specifically, the end of the movable mounting member 031 facing the second side plate 0324 may have a first connecting portion 0311, and the wall surface of the second side plate 0324 facing the movable mounting member 031 may have a second connecting portion 032b, so that the first connecting portion 0311 and the second connecting portion 032b can be arranged opposite to each other, and the first connecting portion 0311 can pass through the through hole 032a and extend into the interior of the salt-containing cavity 0321, that is, the first connecting portion 0311 is located between the first side plate 0323 and the second side plate 0324.

[0042] The opposite sides of the door 033 can be respectively positioned opposite to the second side plate 0324 and the movable mounting part 031, and the door 033 is located between the second side plate 0324 and the movable mounting part 031, so that the opposite sides of the door 033 can slide and engage with the first connecting part 0311 and the second connecting part 032b respectively, thereby allowing the door 033 to move relative to the box body 032. More specifically, the door 033 can move towards the salt inlet 0322 to close the salt inlet 0322, so as to seal the box body 032 and prevent dust from entering the salt chamber 0321. The door 033 can also move away from the salt inlet 0322 to open the salt inlet 0322, so as to facilitate the replenishment of salt particles into the salt chamber 0321. The door 033 can easily open and close the salt inlet 0322.

[0043] Please see Figure 1 and Figure 2 In some embodiments, the door body 033 is provided with a first connector 0331 and a second connector 0332 on opposite sides. The first connecting part 0311 is a first arc-shaped slide rail, and the first connector 0331 slides in cooperation with the first connecting part 0311. The second connecting part 032b is a second arc-shaped slide rail, and the second connector 0332 slides in cooperation with the second connecting part 032b. The first arc-shaped slide rail and the second arc-shaped slide rail bend and extend in the same direction so that the door body 033 can rotate between opening the salt inlet 0322 and closing the salt inlet 0322.

[0044] Optionally, the door body 033 may include a door panel, a first connector 0331 and a second connector 0332. The door panel is a rectangular plate structure. The first connector 0331 and the second connector 0332 may be provided on opposite sides of the door panel. The first connector 0331 and the second connector 0332 may be located between the movable mounting member 031 and the second side panel 0324, so that the first connector 0331 may be disposed opposite to the first connecting part 0311 and the second connector 0332 may be disposed opposite to the second connecting part 032b.

[0045] Since the first connecting part 0311 is a first arc-shaped slide rail and the second connecting part 032b is a second arc-shaped slide rail, the first connecting member 0331 can slide with the first connecting part 0311, and the second connecting member 0332 can slide with the second connecting part 032b. Furthermore, the first arc-shaped slide rail and the second arc-shaped slide rail can bend and extend in the same direction, so that the first connecting member 0331 and the second connecting member 0332 can move synchronously along the same bending trajectory. The second arc-shaped slide rail bends and extends from the bottom edge of the second side plate 0324 to the second side edge that defines the salt inlet 0322. Thus, the first connecting member 0331 and the second connecting member 0332 can drive the door panel to rotate relative to the box body 032, so that the door body 033 can rotate towards the box body 032 to close the salt inlet 0322, and the door body 033 can rotate away from the box body 032 to open the salt inlet 0322, further facilitating the opening and closing of the salt inlet 0322 by the door body 033.

[0046] In this embodiment, the first arc-shaped slide rail is an arc-shaped groove, with the groove opening facing the first connector 0331, so that the first connector 0311 can be inserted into the arc-shaped groove, thereby allowing the first connector 0331 to slide along the curvature direction of the arc-shaped groove. The second arc-shaped slide rail is an arc-shaped hole, which penetrates the inner and outer surfaces of the second side plate 0324, so that the second connector 032b can be inserted into the arc-shaped hole, thereby allowing the second connector 0332 to slide along the curvature direction of the arc-shaped hole, which is the same as the curvature direction of the arc-shaped groove.

[0047] Please see Figures 1 to 4 In some embodiments, the door 033 also has a rotating member 0333, and the box 032 also has a rotating mounting member 0325, with the rotating member 0333 and the rotating mounting member 0325 being rotatably connected.

[0048] Specifically, the door body 033 includes a door panel, and the bottom of the door panel can be provided with a rotating component 0333, which can be a rotating shaft. The salt inlet 0322 on the box body 032 can be provided with a rotating mounting component 0325, which can be a bearing seat, so that the rotating component 0333 can be rotatably connected to the rotating mounting component 0325, thereby allowing the door body 033 to rotate relative to the box body 032. By rotatably connecting the rotating component 0333 to the rotating mounting component 0325, the door body 033 can rotate more stably.

[0049] In this embodiment, the door body 033 may be provided with two rotating parts 0333 at intervals, and the box body 032 may be provided with two rotating mounting parts 0325 at intervals. The two rotating parts 0333 are respectively rotatably connected to the two rotating mounting parts 0325, which further increases the stability of the rotation of the door body 033.

[0050] Please see Figures 1 to 5In some embodiments, the first connector 0331 is provided with a first protrusion 033a, and the second connector 0332 is provided with a second protrusion 033b. The first protrusion 033a is inserted into the first connecting portion 0311 and is slidably connected to the first connecting portion 0311, and the second protrusion 033b is inserted into the second connecting portion 032b and is slidably connected to the second connecting portion 032b.

[0051] Optionally, both the first connector 0331 and the second connector 0332 are plate-shaped structures. The first connector 0331 can be connected to the door body 033, and the first connector 0331 and the door body 033 are set at an angle. The second connector can be connected to the door body 033, and the second connector 0332 is set at an angle to the door body 033. The first connector 0331 and the second connector 0332 are both located on the same side of the door body 033, and the first connector 0331 and the second connector 0332 can be set parallel to each other.

[0052] The first connector 0331 may have a first protrusion 033a on the side facing away from the second connector 0332, and the first protrusion 033a protrudes toward the first connecting part 0311, so that the first protrusion 033a can be inserted into the first connecting part 0311, thereby the first protrusion 033a can be slidably connected with the first connecting part 0311. The second connector 0332 may have a second protrusion 033b on the side facing away from the first connector 0331, and the second protrusion 033b protrudes toward the second connecting part 032b, so that the second protrusion 033b can be inserted into the second connecting part 032b, thereby the second protrusion 033b can be slidably connected with the second connecting part 032b, and thus the door 033 can rotate relative to the box 032.

[0053] Please see Figure 3 In some embodiments, the through hole 032a can be interference-fitted with the outer wall of the movable mounting member 031, so that the movable mounting member 031 can be connected to the housing 032, which can further increase the stability of the movable mounting member 031, so that the door 033 can move stably relative to the housing 032, and can also connect the housing 032 to the external component 12.

[0054] Please see Figure 2 and Figure 3 In some embodiments, the outer side wall of the movable mounting member 031 is provided with a plurality of protruding ribs 0312, and the plurality of protruding ribs 0312 are arranged sequentially at intervals along the circumference of the movable mounting member 031, and the through hole 032a is interference-fitted with the plurality of protruding ribs 0312.

[0055] Specifically, the outer wall of the movable mounting part 031 is provided with a plurality of protruding ribs 0312. The protruding ribs 0312 can protrude outward relative to the outer wall of the movable mounting part 031, and the plurality of protruding ribs 0312 are arranged sequentially at intervals along the circumference of the movable mounting part 031. When the movable mounting part 031 is inserted into the through hole 032a, the plurality of protruding ribs 0312 contact the inner wall surface of the through hole 032a. By providing a plurality of protruding ribs 0312, the contact area between the movable mounting part 031 and the through hole 032a can be reduced, so that the movable mounting part 031 can be inserted into the through hole 032a more easily.

[0056] In addition, the inner wall surface of the through hole 032a can be interference-fitted with multiple ribs 0312, so that multiple ribs 0312 and the inner wall surface of the through hole 032a can form multiple contact points. Multiple contact points can be evenly distributed on the peripheral side wall of the movable mounting part 031, so that the movable mounting part 031 can be installed more stably in the through hole 032a. Setting multiple ribs 0312 can also increase the structural strength of the movable mounting part 031, so that the door body 033 can rotate more stably.

[0057] Please see Figure 2 In some embodiments, the rib 0312 can be connected to the external component 12, thereby connecting the movable mounting part 031 to the external component 12, so that the movable mounting part 031 can be more stably fixed to the external component 12.

[0058] Please see Figure 2 and Figure 3 In some embodiments, the rib 0312 has a guide slope 031a, which guides the movable mounting part 031 into the through hole 032a.

[0059] Specifically, the end of the protruding rib 0312 away from the external connector has a guide slope 031a. During the process of inserting the movable mounting part 031 into the through hole 032a, the guide slope 031a first contacts the inner wall surface of the through hole 032a. The guide slope 031a can be used to guide the movable mounting part 031 into the through hole 032a, which can facilitate the insertion of the movable mounting part 031 into the through hole 032a.

[0060] In some embodiments, the external component 12 is the inner shell of the water purifier.

[0061] Specifically, the salt tank assembly 030 is one of the multiple components of the water purifier. The salt tank assembly 030 is used to replenish salt in the resin tank. The water purifier includes a middle shell, which can be arranged side by side with the salt tank assembly 030. The middle shell is located on the side where the first side plate 0323 of the housing 032 is located. The movable mounting part 031 is connected to the middle shell, which can be easily inserted into the through hole 032a.

[0062] Secondly, this application embodiment also provides a water softening system (not shown in the figure), the water softening system includes a resin tank (not shown in the figure) and a salt tank assembly 030 communicating with the resin tank, the salt tank assembly 030 being the salt tank assembly 030 described above.

[0063] The beneficial effects of the water softening system in this application are the same as those of the salt tank assembly 030 in this application, and will not be repeated here.

[0064] Thirdly, this application also provides a water purifier (not shown in the figure), which includes a housing assembly (not shown in the figure), a water softening system, a water purification system (not shown in the figure), and a hot water system (not shown in the figure). The water softening system, the water purification system, and the hot water system are all disposed within the housing assembly. The water purification system is connected to the water softening system through a first pipe, and the hot water system is connected to the water purification system through a second pipe.

[0065] Specifically, the water softening system can be connected to the tap water supply. The water softening system can soften the tap water to form soft water. The soft water can flow into the water purification system. After being filtered by the water purification system, the soft water becomes pure water. The pure water can flow into the hot water system. After being heated by the hot water system, the pure water can become hot water for users. The beneficial effects of the water purifier are the same as those of the salt tank component 030 in this application, and will not be described again here.
