[0035] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0036] In the description of the present application, it should be noted that the directions or position relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application in that the devices or elements indicated thereby must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0038] Referring to Figure 1 and Figure 3 , the present application provides a salt box structure, comprising a salt box 1, a support 2 and a limiting structure 4. The salt box 1 is provided with a containing cavity 11, and the bottom of the salt box 1 is provided with a water interface 12. The containing cavity 11 of the salt box 1 is used to contain soft water salt blocks 3, and the water interface 12 is used to supplement water into the salt box 1 or output saturated brine in the salt box 1.

[0039] The limiting structure 4 is arranged in the salt box 1 to support the support 2, the support 2 is arranged in the containing cavity 11 to support the salt block 3, and the support 2 is arranged in the bottom wall of the salt box 1 with a spacing, and the support 2 is provided with a plurality of through holes 21. The support 2 can be arranged with a spacing from the bottom wall of the salt box 1 by the support of the limiting structure 4, thereby forming a space in the lower part of the salt box 1. When water is supplemented into the salt box 1 through the water interface 12, the accumulation of water can contact and dissolve the salt block 3 through the through hole 21 to form a salt solution. Since the density of the salt solution is greater than that of water, the salt solution will sink to the bottom of the salt box 1, and then be output through the water interface 12.

[0040] The support 2 of the salt box structure 10 is carried in the salt box 1 by the limiting structure 4, and is arranged to be spaced from the bottom wall of the salt box 1 and to carry the salt blocks 3. In this way, a large space is provided between the bottom wall of the salt box 1 and the support 2 to facilitate the full and uniform dissolution of soft water salt, so that the saturated brine content of the salt solution output by the water outlet 12 is higher. Moreover, the support 2 is not integrally formed with the salt box 1, which simplifies the structure of the salt box 1 forming mold and the forming process, and is conducive to reducing costs.

[0041] Specifically, the limiting structure 4 is arranged on the inner side wall of the salt box 1, and the support 2 is arranged in the receiving cavity 11, and the limiting structure 4 carries the circumferential edge of the support 2. The limiting structure 4 arranged on the inner side wall of the salt box 1 can reduce the space occupied below the support 2, thereby ensuring that the dissolution space is large enough, and the limiting structure 4 is carried on the circumferential edge of the support 2. The circumferential edge of the support 2 generally does not have a through hole 21, therefore, the arrangement of the limiting structure 4 does not affect the dissolution of the salt blocks 3 by water through the through hole 21.

[0042] The limiting structure 4 includes a limiting groove, which is recessed on the inner side wall of the salt box 1 and is adapted to the circumferential edge of the support 2. The support 2 is arranged in the receiving cavity 11 and its circumferential edge is clamped in the limiting groove. The limiting groove is recessed on the inner side wall of the salt box 1, which not only clamps the circumferential edge of the support 2 in the limiting groove to stably carry the support 2, but also does not occupy the space below the support 2 to ensure a large enough dissolution space. The limiting groove can be integrally formed when the salt box 1 is injection molded, which is simple in process.

[0043] And / or, in combination Figure 2 The limiting structure includes a plurality of limiting ribs 41 arranged at intervals, the limiting ribs 41 are protruded on the inner side wall of the salt box 1, and the support 2 is arranged in the receiving cavity 11 and its circumferential edge is arranged on the limiting ribs 41. The limiting ribs 41 are arranged on the inner side wall of the salt box 1, which are located at the edge area of the space below the support 2, which not only occupies a small space, but also has little effect on the flow of salt solution, and basically does not affect the full and uniform dissolution of soft water salt.

[0044] Moreover, the inner side wall of the salt box 1 is provided with a plurality of reinforcing ribs 42, which avoid the arrangement of the water outlet 12 and the support 2. The arrangement of the reinforcing ribs 42 can improve the structural strength of the salt box 1, and avoid the use of the salt box 1 due to the excessive weight of the salt blocks 3. Moreover, the reinforcing ribs 42 avoid the arrangement of the water outlet 12 and the support 2, which does not affect the water replenishment at the water outlet 12 or the output of saturated brine, and does not affect the flow path of water through the through hole 21 to dissolve the salt blocks 3 and the salt solution, thereby ensuring that the water outlet 12 can output a salt solution with high saturated brine content.

[0045] On this basis, the reinforcing ribs 42 are equal in number to the limiting ribs 41 and one-to-one corresponding in position, the reinforcing ribs 42 extend upward from the top end of the limiting ribs 41, the reinforcing ribs 42 are convexly arranged on the inside wall of the salt box 1, the width of the reinforcing ribs 42 decreases from bottom to top, and the bottom end of the reinforcing ribs 42 contacts the bottom end edge of the support 2. The reinforcing ribs 42 and the limiting ribs 41 can be an integral structure, and the two are cooperatively arranged to enable the support 2 to be clamped at the connection between the two, and the inclined structure of the reinforcing ribs 42 also facilitates the disassembly of the support 2.

[0046] In addition, the bottom surface of the support 2 is higher than the inner diameter top point of the water interface 12. After the salt solution is formed by dissolving the salt block 3 through the through hole 21, the water needs to sink first, and then is discharged through the water flow of the water interface 12, which increases the flow path of the salt solution in the salt box 1, and is beneficial to the uniform dissolution of the salt solution to form more saturated brine.

The through hole 2021 is generally arranged on the opposite two side surfaces with the open mouth 2022, so that when the salt box structure 10 is installed in the salt box cavity 202 through the open mouth 2022, the water interface 12 can be quickly and accurately inserted into the through hole 2021.

[0051] The clamping structure includes a clamping protrusion 2023 arranged on the inner wall of the salt box cavity 202 and a clamping groove arranged on the outer wall of the salt box 1 corresponding to the clamping protrusion 2023.
