[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the water softener provided by the embodiment of the utility model includes a shell, a salt box 200 and a resin tank 300. The shell includes a base 110, a first side plate 120 and a second side plate 130. The first side plate 120 and the second side plate 130 are relatively arranged at the edge of the base 110 in the width direction of the shell, and at least one of the first side plate 120 and the second side plate 130 is plugged into the base 110; the salt box 200 is connected to the base 110, and the salt box 200 is clamped between the first side plate 120 and the second side plate 130; the resin tank 300 and the salt box 200 are arranged in sequence along the length direction of the shell, and the resin tank 300 is connected to the base 110, and the resin tank 300 is clamped between the first side plate 120 and the second side plate 130.

[0040] The water softener of the embodiment of the utility model has an outer shell that defines an accommodating space through a base 110, a first side panel 120, and a second side panel 130. The outer shell is mainly divided into six directions: front, rear, left, right, upper, and lower. The front and rear directions are the length directions of the outer shell, the left and right directions are the width directions of the outer shell, i.e., the positions of the first side panel 120 and the second side panel 130. The upper and lower directions are the height directions of the outer shell. The base 110 is arranged at the lower side of the height direction of the outer shell, and the salt box 200 and the resin tank 300 are arranged in sequence from front to back in the accommodating space.

[0041] Compared with the prior art, in which the rear cover 150 is connected to the rest of the shell after the resin tank 300 is installed inside the shell to complete the assembly, so that there is always a certain distance between the shell and the resin tank 300, the overall volume of the shell 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 resin tank 300 and the salt box 200 are first installed on the base 110 according to the setting position, and then the first side plate 120 and the second side plate 130 are connected to the base 110. The first side plate 120 and the second side plate 130 are relatively arranged on both side edges of the base 110 in the width direction, and at least one of the two is connected to the base 110 in the form of direct plugging, and the first side plate 120 and the second side plate 130 are relatively arranged on both side edges of the base 110 in the width direction. The installation position of the side plate 120 and the second side plate 130 allows the resin tank 300 and the salt box 200 to be sandwiched between the first side plate 120 and the second side plate 130, which can realize that the first side plate 120 and the second side plate 130 as part of the shell directly encapsulate the resin tank 300 and the salt box 200 at the nearest position outside the resin tank 300 and the salt box 200, improve the compactness of the first side plate 120 and the second side plate 130 as the shell structure, and reduce the overall space volume of the water softener. On this basis, compared with the assembly method of bolt installation, at least one of the first side plate 120 and the second side plate 130 is directly connected to the base 110 in the form of plug-in, which is more convenient for disassembly and assembly of the water softener. The direct connection between the salt box 200 and the resin tank 300 and the base 110 improves the firmness of the installation of the salt box 200 and the resin tank 300.

[0042] In this embodiment, both the first side plate 120 and the second side plate 130 are connected to the base 110 in a plug-in manner. In other embodiments, any one of them can be plug-connected to the base 110 .

[0043] like Figure 3 and Figure 4 As shown, according to one embodiment of the utility model, the base 110 is provided with one of the first socket 140 and the first plug block 111, the bottom of at least one of the first side panel 120 and the second side panel 130 is provided with the other of the first socket 140 and the first plug block 111, and the first plug block 111 is inserted into the first socket 140. In this embodiment, the plug-in connection between the base 110 and the first side plate 120 and the second side plate 130 is achieved through the first plug hole 140 and the first plug block 111. The first plug hole 140 and the first plug block 111 can be formed on the base 110 and the first side plate 120 and the second side plate 130 respectively, and the plug-in connection can be performed by corresponding cooperation. The first plug block 111 is inserted into the first plug hole 140, and the first plug hole 140 limits and fixes the first plug block 111, thereby connecting the first side plate 120 and the second side plate 130 to the base 110. The first plug hole 140 releases the limit on the first plug block 111, and the first plug block 111 withdraws from the first plug hole 140, thereby separating the first side plate 120 and the second side plate 130 from the base 110.

[0044] In this embodiment, the first plug block 111 is arranged on the base 110, and the first plug hole 140 is arranged on the first side plate 120 and the second side plate 130. There are six first plug holes 140 in total, three at the bottom of the first side plate 120 and three at the bottom of the second side plate 130, and they are evenly arranged along the length direction of the shell, and six first plug blocks 111 are arranged at corresponding positions on the edge of the base 110. In other embodiments, the arrangement positions and quantities of the first plug blocks 111 and the first plug holes 140 can be selected according to actual needs.

[0045] like Figure 4 As shown, according to an embodiment of the present invention, a first convex edge 141 is provided at the bottom of at least one of the first side plate 120 and the second side plate 130, the first convex edge 141 extends toward the inside of the shell, the first convex edge 141 is provided with a first plug hole 140, and the base 110 is provided with a first plug block 111 extending upward. In this embodiment, when forming the first plug hole 140, the first side plate 120 and the second side plate 130 are both formed by the first convex edge 141 extending from the bottom of the plate body into the accommodating space, that is, the bottom of the first side plate 120 extends horizontally toward the second side plate 130 along the width direction of the shell to form the first convex edge 141, and the bottom of the second side plate 130 extends horizontally toward the first side plate 120 along the width direction of the shell to form the first convex edge 141.

[0046] In this embodiment, the first protrusion 141 has a certain width in the width direction of the shell and a certain length in the length direction of the shell. The first plug hole 140 is formed on the first protrusion 141 along the height direction of the shell. The upper surface of the base 110 is provided with a first plug block 111 extending upward at a corresponding position. When the first side plate 120 and the second side plate 130 move downward, the first plug block 111 can be inserted into the first plug hole 140, thereby realizing the detachable connection between the first side plate 120 and the second side plate 130 and the base 110 respectively.

[0047] like Figure 4 and Figure 6As shown, according to an embodiment of the utility model, the base 110 is provided with a first protrusion 112, and the first protrusion 112 is surrounded to form a closed ring. The inner side of the first protrusion 112 is the installation area of ​​the resin tank 300, and the outer side of the first protrusion 112 is the installation area of ​​the first side plate 120 and the second side plate 130. In this embodiment, the installation area of ​​the resin tank 300 is delimited by providing a first protrusion 112 with a certain height on the upper surface of the base 110, and the first protrusion 112 is surrounded in a ring shape. The fixed position of the resin tank 300 on the base 110 needs to be within the closed ring surrounded by the first protrusion 112, and the plug-in position of the first side plate 120 and the second side plate 130 on the base 110 needs to be outside the closed ring surrounded by the first protrusion 112, so as to avoid mutual interference between the installation positions of the first side plate 120, the second side plate 130 and the resin tank 300.

[0048] An electronic leakage protection sensor is provided at the bottom of the resin tank 300 near the base 110, and the first protrusion 112 is arranged around the outside of the resin tank 300. If the resin tank 300 leaks, the closed-loop first protrusion 112 can store the leaked liquid at a certain height, thereby preventing the liquid from flowing out of the base 110 to a certain extent. At the same time, the electronic leakage protection sensor can detect the liquid in time, thereby quickly responding to the problem of leakage in the resin tank 300.

[0049] like Figure 4 and Figure 6 As shown, according to an embodiment of the present invention, the first protrusion 112 is bent at a position corresponding to the first inserting block 111 to match the shape of the first protruding edge 141 . In this embodiment, when the first plug block 111 is provided on the base 110, the first side plate 120 and the second side plate 130 are provided with the first flange 141 and the first insertion hole 140 is constructed on the first flange 141, the first protrusion 112 is bent around the first plug block 111, and the shape of the bend is consistent with the shape of the first flange 141, that is, a groove body in the shape of the first flange 141 is formed around the first plug block 111, and the first flange 141 falls onto the surface of the base 110. After the first plug block 111 is inserted into the first insertion hole 140, the first flange 141 is embedded in the groove body, so that the first flange 141 is given way without preventing the first flange 141 from contacting the base 110. At the same time, the position of the first flange 141 can also be limited, thereby helping to enhance the stability of the plug-in connection between the first side plate 120 and the second side plate 130 on the base 110.

[0050] In other embodiments, when the first socket 140 is provided on the base 110, the first side panel 120 and the second side panel 130 are connected to the first socket 140 by providing the first plug block 111, so as to realize the plug-in connection between the base 110 and the first side panel 120 and the second side panel 130, the first side panel 120 and the second side panel 130 only need to provide the first plug block 111 vertically downward at the bottom, so the first protrusion 112 does not need to be bent.

[0051] like Figure 3 and Figure 5 As shown, according to an embodiment of the present invention, the housing further comprises a rear cover plate 150, the base 110 is provided with one of the second plug hole 151 and the second plug block 113, the bottom of the rear cover plate 150 is provided with the other of the second plug hole 151 and the second plug block 113, and the second plug block 113 is inserted into the second plug hole 151. In this embodiment, the rear cover plate 150 is arranged at the rear side in the length direction of the housing, after the resin tank 300 and the salt box 200 are fixed on the base 110, the rear cover plate 150 is first directly clamped with the resin tank 300, and then the first side plate 120 and the second side plate 130 are plugged into the base 110 to assemble the housing. The plug-in connection between the base 110 and the rear cover 150 is achieved through the second plug block 113 and the second socket 151. The second plug block 113 and the second socket 151 can be formed on the base 110 and the rear cover 150 respectively, and the plug-in connection can be achieved by corresponding cooperation. The second plug block 113 is inserted into the second socket 151, and the second socket 151 limits and fixes the second plug block 113, thereby connecting the rear cover 150 to the base 110. The second socket 151 releases the limit on the second plug block 113, and the second plug block 113 withdraws from the second socket 151, thereby separating the rear cover 150 from the base 110.

[0052] In this embodiment, the second plug block 113 is disposed on the base 110, the second plug hole 151 is disposed on the rear cover 150, there is one second plug hole 151, and a second plug block 113 is disposed at a corresponding position on the edge of the base 110. In other embodiments, the location and quantity of the second plug block 113 and the second plug hole 151 can be selected according to actual needs.

In this embodiment, when the second plug hole 151 is formed, the rear cover plate 150 is formed by extending the second convex edge 152 formed at the bottom of the plate body into the accommodating space, that is, the bottom of the rear cover plate 150 extends horizontally toward the resin tank 300 along the length direction of the shell to form the second convex edge 152.

[0054] In this embodiment, the second protrusion 152 has a certain length in the width direction of the shell and a certain width in the length direction of the shell. The second plug hole 151 is formed on the second protrusion 152 along the height direction of the shell. The upper surface of the base 110 is provided with a second plug block 113 extending upward at a corresponding position. When the rear cover 150 moves downward, the second plug block 113 can be inserted into the second plug hole 151, thereby realizing the detachable connection between the rear cover 150 and the base 110.

[0055] like Figure 5 and Figure 6 As shown, according to an embodiment of the present invention, the first protrusion 112 forms a bend that matches the shape of the second flange 152 at a position corresponding to the second plug block 113. In this embodiment, when the second plug block 113 is provided on the base 110, and the rear cover 150 is provided with the second flange 152 and the second insertion hole 151 is constructed on the second flange 152, the first protrusion 112 is bent around the second plug block 113, and the shape of the bend is consistent with the shape of the second flange 152, that is, a groove body in the shape of the second flange 152 is formed around the second plug block 113, and the second flange 152 falls on the surface of the base 110. After the second plug block 113 is inserted into the second insertion hole 151, the second flange 152 is embedded in the groove body, so as to make way for the second flange 152, without preventing the second flange 152 from contacting the base 110, and at the same time, the position of the second flange 152 can be limited, thereby helping to enhance the stability of the plug-in connection of the rear cover 150 on the base 110.

[0056] In other embodiments, when the second socket 151 is provided on the base 110, the rear cover 150 is connected to the second socket 151 by providing a second plug block 113, so that the base 110 and the rear cover 150 are plugged in, the rear cover 150 only needs to provide the second plug block 113 vertically downward at the bottom, so the first protrusion 112 does not need to be bent.

[0057] like Figure 6 As shown, according to an embodiment of the utility model, the base 110 is provided with a second protrusion 114, and the second protrusion 114 is arranged around the salt box 200. In this embodiment, the installation area of ​​the salt box 200 is delimited by arranging a second protrusion 114 with a certain height on the upper surface of the base 110. The second protrusion 114 can be surrounded in a closed ring, or it can be open by itself, and cooperate with the first protrusion 112 to form a closed ring. The fixed position of the salt box 200 on the base 110 needs to be within the closed ring surrounded by the second protrusion 114, and the plug-in position of the first side plate 120 and the second side plate 130 on the base 110 needs to be outside the closed ring surrounded by the second protrusion 114, so as to avoid mutual interference between the installation positions of the first side plate 120, the second side plate 130 and the salt box 200.

[0058] In this embodiment, the height of the first protrusion 112 is greater than that of the second protrusion 114 . Since the salt box 200 itself does not require leakage detection, the height setting of the second protrusion 114 is limited to assisting the installation and positioning of the salt box 200 .

[0059] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, according to one embodiment of the utility model, the bottom surface of the base 110 is provided with an upward groove 115, the bottom surface of the groove 115 is provided with a positioning hole 117, at least one of the resin tank 300 and the salt box 200 is connected to the positioning hole 117 by a fastener, and an anti-slip pad 116 is embedded in the groove 115. In this embodiment, the base 110 forms a detachable fixed connection with at least one of the resin tank 300 and the salt box 200, the base 110 forms a groove 115 upward from the bottom surface, and a positioning hole 117 penetrating upward is provided at the bottom of the groove 115, at least one of the resin tank 300 or the salt box 200 is placed on the positioning hole 117, and its own connection hole is aligned with the positioning hole 117, and the fastener passes through the positioning hole 117 and the connection hole from bottom to top in sequence, so that at least one of the resin tank 300 or the salt box 200 is connected to the base 110. The anti-skid pad 116 is then embedded in the groove 115. On the one hand, it can increase the friction of the bottom surface of the base 110 to prevent the softener from sliding on the smooth surface. On the other hand, the groove 115 can be blocked to prevent the fasteners inside it from being exposed, thereby improving the reliability of the connection between at least one of the resin tank 300 or the salt box 200 and the base 110 through the fasteners.

[0060] In this embodiment, in order to assist the resin tank 300 and at least one of the salt boxes 200 in positioning and aligning the connection holes with the positioning holes 117 on the base 110, a protrusion 118 is formed around the positioning holes 117 on the upper surface of the base 110, and the corresponding resin tank 300 and at least one of the salt boxes 200 are provided with a depression matching the protrusion 118 at the connection hole. After the protrusion 118 is embedded in the depression, the positioning hole 117 and the connection hole are aligned, which is convenient for installing fasteners.

[0061] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
