In the water production mode, raw water can be fed into the resin tank 300 through the softening valve 400, and the raw water in the resin tank 300 is softened by the resin to obtain soft water, which is then fed back to the softening valve 400. The user can get soft water from the soft water outlet of the softening valve 400. In the water injection mode, the salt tank 200 can be injected into the resin tank 300 through the softening valve 400. Water, the water injected into the salt box 200 can be raw water or soft water, so that the water dissolves the salt in the salt box 200; after the water is injected into the salt box 200, the salt in the salt box 200 can be dissolved for a period of time, and this process can be called the salt melting mode; in the salt absorption mode, the salt water in the salt box 200 is sent to the resin tank 300 through the soft water valve 400, and the water that has cleaned the resin in the resin tank 300 is discharged through the soft water valve 400; in the cleaning mode, the raw water is passed into the resin tank 300 through the soft water valve 400, and the water that has cleaned the resin tank 300 is then discharged through the soft water valve 400.

[0045] like Figure 1 and Figure 2 As shown, the water softener provided by the embodiment of the utility model includes a shell 100, a salt box 200 and a resin tank 300. The shell 100 encloses a containing space, and the shell 100 includes a rear cover plate 110; the salt box 200 is arranged in the containing space; the resin tank 300 is arranged in the containing space and is located between the rear cover plate 110 and the salt box 200, and the rear cover plate 110 is snap-connected with the resin tank 300.

[0046] In the water softener of the embodiment of the utility model, an accommodating space is set inside the shell 100, and the rear cover 110 as a part of the shell 100 can be used to enclose the accommodating space. The shell 100 is mainly divided into six directions: front, rear, left, right, upper and lower, wherein the front and rear directions are the length directions of the shell 100, the left and right directions are the width directions of the shell 100, and the upper and lower directions are the height directions of the shell 100. The rear cover 110 is arranged on the rear side of the length direction of the shell 100, and the salt box 200 and the resin tank 300 are arranged in sequence from front to back in the accommodating space.

[0047] Compared with the prior art, in which the rear cover 110 is connected to the rest of the shell 100 after the resin tank 300 is loaded into the shell 100 to complete the assembly, so that there is always a certain distance between the rear cover 110 and the resin tank 300, the overall volume of the shell 100 will be larger, and the overall structure of the water softener is not compact enough, during the assembly process of the water softener of the utility model, the rear cover 110 and the resin tank 300 are directly snapped together first, and then the other parts of the shell 100 are assembled, which can not only realize that the rear cover 110 as a part of the shell 100 directly encapsulates the resin tank 300 at the nearest position outside the resin tank 300, but also improve the compactness of the structure between the rear cover 110 as the shell 100 and the water softening component, reduce the overall spatial volume of the water softener, but also realize the direct connection between the rear cover 110 and the resin tank 300, and improve the firmness of the installation of the rear cover 110. On this basis, compared with the assembly method of bolt installation, the direct connection between the rear cover plate 110 and the resin tank 300 through the snap-fit ​​form is more convenient for disassembly and assembly of the water softener.

[0048] like Figure 2 As shown, according to an embodiment of the utility model, one of the resin tank 300 and the rear cover plate 110 is provided with a slot 310, and the other of the resin tank 300 and the rear cover plate 110 is provided with a hook 111, and the hook 111 is inserted into the slot 310. In this embodiment, the snap connection between the resin tank 300 and the rear cover plate 110 is realized by the hook 111 and the slot 310. The hook 111 and the slot 310 can be formed on the resin tank 300 and the rear cover plate 110, respectively, and can be snap-connected by corresponding cooperation. The hook 111 is inserted into the slot 310, and the slot 310 limits and fixes the hook 111, thereby connecting the rear cover plate 110 with the resin tank 300. The slot 310 releases the limit of the hook 111, and the hook 111 withdraws from the slot 310, thereby separating the rear cover plate 110 from the resin tank 300.

[0049] In this embodiment, the hook 111 is arranged on the rear cover 110, and the slot 310 is arranged on the resin tank 300. There are six hooks 111 in total, and three hooks 111 are evenly arranged on both sides of the rear cover 110 in the width direction, and six slots 310 are arranged at corresponding positions of the resin tank 300. In other embodiments, the arrangement positions and numbers of the hooks 111 and the slots 310 can be selected according to actual needs.

[0050] like Figure 3 and Figure 4 As shown, according to one embodiment of the utility model, the rear cover plate 110 includes a plate body 112 and a flange 113, the width of the plate body 112 is less than or equal to the width of the resin tank 300; the flange 113 is arranged on both side edges of the plate body 112 along the height direction of the plate body 112, the flange 113 extends toward the accommodating space, the flange 113 is provided with a notch 114, and the hook 111 is arranged in the notch 114.

[0051] In this embodiment, the rear cover 110 is mainly divided into three parts along its width direction, one part is the plate body 112, and the other two parts are flanges 113 respectively located at the two side edges of the plate body 112 in the width direction. It can also be understood that the two side edges of the rear cover 110 in the width direction are bent toward the direction of the accommodating space, the length direction of the flange 113 is the height direction of the plate body 112, and the width direction of the flange 113 is the extension direction toward the accommodating space. Therefore, the width of the plate body 112 is the width of the rear cover 110 itself. In order to minimize the volume of the outer shell 100, the width of the rear cover 110 needs to be no greater than that of the resin tank 300, so that the width of the outer shell 100 is as close to the width of the resin tank 300 as possible. After the other parts of the outer shell 100 are installed, there is no other remaining space in the width direction.

[0052] The flange 113 is provided with a notch 114, and the hook 111 is arranged at the notch 114, which can keep the same position with the flanges 113 on both sides of the notch 114, that is, the hook 111 and the flange 113 are formed into one body, further making the structure of the rear cover 110 compact and integrated, and not occupying much other structures and space positions.

[0053] In this embodiment, the width of the plate body 112 is the same as the width of the resin tank 300, that is, the outer surface of the flange 113 is flush with the outer surface of the resin tank 300 at the maximum width. Since the hook 111 is integrated with the flange 113, a corresponding depression is arranged on the resin tank 300 to form a slot 310. After the hook 111 is inserted into the slot 310, it can also ensure that the connection position between the resin tank 300 and the rear cover plate 110 is flat and has no protrusions, and will not increase the width of the outer shell 100.

[0054] In this embodiment, a first connection hole 118 for connecting the left side plate 150 is also provided on the flange 113 of the left side plate 150 of the corresponding shell 100, and a second connection hole 119 for connecting the right side plate 160 is also provided on the flange 113 of the right side plate 160 of the corresponding shell 100.

[0055] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, according to an embodiment of the utility model, the resin tank 300 is provided with a positioning hole 320, and the rear cover plate 110 is provided with a plurality of positioning posts 115, which are inserted into the positioning holes 320, and the plurality of positioning posts 115 are evenly distributed along the height direction of the rear cover plate 110. In this embodiment, the resin tank 300 and the rear cover plate 110 are also matched through a positioning portion. During the connection between the rear cover plate 110 and the resin tank 300, the positioning posts 115 of the rear cover plate 110 are inserted into the corresponding positioning holes 320 on the resin tank 300. The positioning holes 320 can limit the movement of the positioning posts 115 within the range involved in the height direction and the width direction of the rear cover plate 110, thereby realizing the positioning and restriction of the rear cover plate 110 during installation.

[0056] In this embodiment, the positioning columns 115 are divided into two groups, both of which are arranged on the plate body 112. The two groups of positioning columns 115 are respectively arranged close to the two flanges 113. Each group of positioning columns 115 is composed of multiple positioning columns 115. The multiple positioning columns 115 are evenly distributed along the height direction of the rear cover plate 110. While limiting the position of the rear cover plate 110, it can also prevent the rear cover plate 110 from deformation, increase the structural strength of the rear cover plate 110, and thus reduce the gap between the flange 113 and the left side plate 150 and the right side plate 160 of the outer shell 100 during installation.

[0057] like Figure 5 and Figure 6 As shown, according to an embodiment of the utility model, the resin tank 300 includes a tank body 330 and a mounting plate 340, the mounting plate 340 is connected to the tank body 330, the mounting plate 340 is located between the tank body 330 and the rear cover plate 110, and the mounting plate 340 is provided with a card slot 310 and a positioning hole 320. In this embodiment, the resin tank 300 is divided into two parts, the tank body 330 and the mounting plate 340, the tank body 330 is provided with a mounting plate 340 on the side facing the rear cover plate 110, the mounting plate 340 and the tank body 330 are connected as a whole, the mounting plate 340 extends along the height direction of the tank body 330, the mounting plate 340 corresponds to the rear cover plate 110, and the corresponding positioning holes 320 and the card slot 310 are both provided on the mounting plate 340, that is, the mounting plate 340 provides a planar structure for the installation connection between the resin tank 300 and the rear cover plate 110, the connection is more convenient, and the structure is more stable and firm.

[0058] It is understandable that the resin tank 300 is cylindrical in shape, and setting the slot 310 and the positioning hole 320 on the outer circumferential wall is not reliable in terms of processing and connection performance. Therefore, a mounting plate 340 is added to the outer wall of the tank body 330. The mounting plate 340 is a flat plate body, and the positioning hole 320 and the slot 310 are constructed on the flat plate to improve the reliability of the connection structure. The interior of the tank body 330 can be composed of two relatively independent cylindrical cavities, and the axial directions of the two cavities are both the height direction of the shell 100, that is, the set volume of resin is divided into two cavities. Compared with the resin tank of the prior art with a single inner cavity structure, under the same height, the inner cavity diameter of the tank body 330 of this embodiment will be reduced, and the width of the overall resin tank 300 will also be reduced, thereby further reducing the width of the water softener.

[0059] like Figure 5 and Figure 6 As shown, according to an embodiment of the utility model, the edge of the mounting plate 340 is provided with a bending portion 341 corresponding to the flange 113, and the bending portion 341 is recessed to form a card slot 310. In this embodiment, the edge of the mounting plate 340 forms a bending portion 341 in the direction of the rear cover plate 110, that is, the bending portion 341 corresponds to the flange 113. After the rear cover plate 110 is connected to the resin tank 300, the flange 113 is superimposed on the outside of the bending portion 341 and fits tightly with the outer surface of the bending portion 341. Since the hook 111 is integrated at the flange 113, the bending portion 341 forms a card slot 310 by recessing at the position corresponding to the hook 111, and is connected with the hook 111.

[0060] The bent portion 341 supports the flange 113 to enhance the structural strength of the flange 113 , and increases the structural compactness of the connection position between the rear cover plate 110 and the resin tank 300 .

[0061] like Figure 2 and Figure 6 As shown, according to an embodiment of the present invention, the mounting plate 340 is further provided with a reinforcing rib 342, and the reinforcing rib 342 abuts against the rear cover plate 110. In this embodiment, the mounting plate 340 is provided with reinforcing ribs 342 between the bent portions 341 at the edges of both sides, and the reinforcing ribs 342 are arranged in multiple layers from top to bottom, and both ends of each layer of reinforcing ribs 342 are connected to two bent portions 341, so as to enhance the structural strength of the mounting plate 340 and prevent the bent portions 341 of the mounting plate 340 from deforming. After the rear cover plate 110 is clipped onto the mounting plate 340, the edge of one side of the reinforcing rib 342 close to the rear cover plate 110 abuts against the inner surface of the plate body 112 of the rear cover plate 110, that is, the reinforcing rib 342 provides support for the plate body 112 in the rigidity direction of the rear cover plate 110, further enhancing the structural strength of the rear cover plate 110 after being installed on the resin tank 300, and preventing deformation.

[0062] like Figure 1 and Figure 4 As shown, according to one embodiment of the utility model, the housing 100 further includes a top cover plate 120, a first fixing hole 116 is provided on the top of the rear cover plate 110, and a first downward protrusion 121 is provided on the top cover plate 120, and the first protrusion 121 is inserted into the first fixing hole 116. In this embodiment, the housing 100 is provided with a top cover plate 120 on the upper side in the height direction thereof, and after the rear cover plate 110 is snapped onto the resin tank 300, the top cover plate 120 is placed above the resin tank 300 and connected to the top of the rear cover plate 110.

[0063] In this embodiment, a first convex edge 1124 of a certain length is formed on the top of the rear cover plate 110 along the length direction of the outer shell 100, and a first fixing hole 116 is formed on the first convex edge 1124 along the height direction of the outer shell 100. The top cover plate 120 is divided into a front end and a rear end in the length direction of the outer shell 100, and the rear end is located above the rear cover plate 110. A first protrusion 121 extending downward is arranged at a position of the rear end corresponding to the first fixing hole 116. When the top cover plate 120 moves downward, the first protrusion 121 can be inserted into the first fixing hole 116, thereby realizing a detachable connection between the top cover plate 120 and the rear end cover.
