Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, and in particular to a housing and a water softener. Background Technology

[0002] Water softeners on the market mainly consist of five core components: a brine tank, a resin tank, a valve control assembly, a supporting middle shell, and a top cover. Their working principle involves using functional ions in the resin tank to exchange calcium and magnesium ions in the water, thereby effectively reducing water hardness. When the resin becomes saturated, it is regenerated using special brine in the brine tank, achieving resin recycling.

[0003] In existing water softener designs, the supporting shell is placed on top of the brine tank, while the rest is suspended inside the brine tank. The top cover and valve control components are also mounted on the supporting shell. This structure forces the brine tank to bear the entire load of the supporting shell, top cover, and valve control components. To prevent deformation, the brine tank wall thickness must be increased, resulting in excessively high material costs. Utility Model Content

[0031] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0032] See Figures 1-6 This illustration shows a preferred embodiment of the housing of the present invention, comprising:

[0033] Salt tank 1, having an inner cavity 11 and a plurality of first support parts 12, the inner cavity 11 for holding brine and resin tank 3, the plurality of first support parts 12 being spaced apart on the side wall of the inner cavity 11; and

[0034] The supporting shell 2 is provided with a connecting base 21 and a first supporting base 22. The connecting base 21 is located on the top of the salt tank 1 to connect the supporting shell 2 to the salt tank 1. The connecting base 21 covers the top opening of the inner cavity 11. The first supporting base 22 is connected to the connecting base 21 and is located inside the inner cavity 11. The first supporting base 22 abuts against the side wall of the inner cavity 11 and is connected to the first supporting part 12 to limit the deformation of the salt tank 1.

[0035] The housing of this utility model features a double-support structure. Multiple spaced-apart first support portions 12 are provided on the side wall of the inner cavity 11 of the salt tank 1. A connecting base 21 and a first support base 22 are added to the supporting shell 2. The connecting base 21 covers the top opening of the salt tank 1 for connection, while the first support base 22 extends into the inner cavity 11, abuts against the side wall of the salt tank 1, and connects with the first support portions 12. This design allows the supporting shell 2 and the side wall of the salt tank 1 to jointly bear the load through the cooperation of the first support base 22 and the first support portions 12, significantly reducing the load-bearing pressure on the salt tank 1. This allows for a reduction in the wall thickness of the salt tank 1 without affecting structural stability, thus lowering material costs. Simultaneously, the double-support structure restricts deformation of the side wall of the salt tank 1, preventing changes to the water level or structure within the salt tank 1, ensuring the normal brine intake of the salt valve 41, and further improving the overall structural rigidity and durability, extending the service life of the water softener.

[0036] In one embodiment, the first support base 22 and the connecting base 21 are integrally formed together, that is, the first support base 22 and the connecting base 21 are integrally formed, so that the first support base 22 can be connected to the connecting base 21 without additional connectors. This eliminates the need for connectors, significantly reduces the number of parts while ensuring installation stability, simplifies the structure, thereby reducing manufacturing costs and simplifying the maintenance process.

[0037] See Figure 6 In one embodiment, the connecting base 21 has a first connecting hole 211, and the salt tank 1 has a second connecting hole located inside the inner cavity 11. The box also includes a fastener, the head of which abuts against the connecting base 21, and the rod of which passes through the first connecting hole 211 and is screwed to the second connecting hole. This not only enables the connecting base 21 and the salt tank 1 to be reliably connected together, but also allows the supporting shell 2 to be disassembled for easy maintenance.

[0038] See Figure 6 In one embodiment, the connecting base 21 is provided with a plurality of positioning protrusions 212, which are arranged at intervals around the vertical center line of the connecting base 21, and all the positioning protrusions 212 abut against the side wall of the inner cavity 11. In this way, the positioning structure is formed by the positioning protrusions 212 abutting against the side wall of the inner cavity 11 of the salt tank 1, which not only ensures the stability and accurate alignment of the installation, but also facilitates maintenance and disassembly, thus optimizing the reliability and ease of use of the overall structure.

[0039] See Figures 5-7In one embodiment, the sidewall of the first support base 22 is provided with a plurality of second support portions 221. The plurality of second support portions 221 are spaced apart around the vertical centerline of the first support base 22, and each of the plurality of second support portions 221 abuts against the sidewall of the inner cavity 11, and the second support portion 221 is connected to the corresponding first support portion 12. In this way, by setting a plurality of spaced second support portions 221 on the first support base 22 to abut against the sidewall of the inner cavity 11 of the salt tank 1, a multi-point uniform support structure is formed, which not only enhances the overall structural stability and improves the resistance to deformation, but also ensures the precise alignment of the first support base 22 and optimizes the stress distribution, significantly improving assembly reliability and long-term service durability.

[0040] See Figures 4-5 In one embodiment, one of the second support portion 221 and the first support portion 12 has a slot 2211 and the other has a snap-fit ​​protrusion 122, which is adapted to the slot 2211. Thus, the slot 2211 and the snap-fit ​​protrusion 122 cooperate to form a locking structure, which not only enhances the connection stability between the first support base 22 and the inner cavity 11 of the salt tank 1, but also achieves rapid and accurate positioning, while optimizing the force distribution and effectively improving the overall structure's impact resistance and long-term reliability.

[0041] See Figures 3-4 In one embodiment, the first support portion 12 includes a support protrusion 121 and the aforementioned snap-fit ​​protrusion 122. The number of support protrusions 121 is at least two. The support protrusions 121 extend vertically along the salt tank 1. Two adjacent support protrusions 121 are spaced apart horizontally along the salt tank 1. The snap-fit ​​protrusion 122 is disposed between the at least two support protrusions 121. The snap-fit ​​protrusion 122 connects to the upper ends of the at least two support protrusions 121 and is spaced apart from the side wall of the inner cavity 11.

[0042] See Figure 5 In one embodiment, the first support base 22 has a salt-adding channel 222 that extends vertically through the first support base 22 and connects to the inner cavity 11 to facilitate adding salt to the inner cavity 11 of the salt tank 1. By providing a vertically extending salt-adding channel 222 in the first support base 22, efficient communication of the inner cavity 11 of the salt tank 1 is achieved, while fully utilizing the three-dimensional spatial structure of the first support base 22. This avoids the need for additional salt-adding components, optimizes the internal spatial layout of the salt tank 1, and significantly improves the overall space utilization efficiency of the structure.

[0043] See Figures 4-5In one embodiment, the supporting shell 2 is further provided with a second supporting base 23, which is connected to the connecting base 21. The second supporting base 23 and the first supporting base 22 are arranged side by side along the length of the salt tank 1. A portion of the second supporting base 23 is located in the inner cavity 11. The side of the second supporting base 23 away from the first supporting base 22 abuts against the side wall of the salt tank 1. The second supporting base 23 is used to support the valve control assembly 4 of the water softener. By adding a second support base 23 to the supporting shell 2 and setting it parallel to the first support base 22 along the length of the salt tank 1, the load distribution structure is further optimized. The second support base 23 extends into the inner cavity 11 of the salt tank 1, and its side away from the first support base 22 directly abuts against the side wall of the salt tank 1, forming a multi-point support structure. This not only enhances the structural stability of the supporting shell 2 and the salt tank 1, but also achieves directional load bearing of key components by specifically supporting the valve control component 4 through the second support base 23. This effectively disperses the concentrated force on the salt tank 1 in the traditional structure, thereby significantly improving the stability and load-bearing balance of the overall structure while reducing the wall thickness requirement of the salt tank 1. Furthermore, this design takes into account both space utilization and assembly convenience through the modular support base layout.

[0044] In one embodiment, the second support base 23 and the connecting base 21 are integrally formed together, that is, the second support base 23 and the connecting base 21 are integrally formed, so that the second support base 23 can be connected to the connecting base 21 without additional connectors. This eliminates the need for connectors, significantly reduces the number of parts while ensuring installation stability, simplifies the structure, thereby reducing manufacturing costs and simplifying the maintenance process.

[0045] See Figure 2 and Figure 6 In one embodiment, the side wall of the salt tank 1 has a support groove 13, and the second support base 23 has a third support part 231 on the side opposite to the first support base 22. The third support part 231 is inserted into the support groove 13. By setting the support groove 13 on the side wall of the salt tank 1 and correspondingly setting the third support part 231 that can be inserted into the support groove 13 on the second support base 23, a mechanical interlocking structure is formed. This not only enhances the connection strength and stability between the support shell 2 and the salt tank 1 and effectively prevents relative displacement between components, but also achieves precise positioning and assembly guidance through the cooperation of the support groove 13 and the third support part 231, simplifying the installation process. At the same time, this plug-in design further optimizes the load transmission path, so that the load of the valve control component 4 is evenly distributed to the side wall of the salt tank 1 through the third support part 231, significantly reducing the risk of structural deformation. While improving product durability, it maintains structural compactness and production economy.

[0046] See Figure 5 and Figure 7 In one embodiment, the support groove 13 penetrates the side wall of the salt tank 1;

[0047] The second support base 23 has a receiving cavity 232 for receiving at least a portion of the valve control assembly 4, specifically for receiving the piston-type multi-way valve 42 in the valve control assembly 4. The third support part 231 has a first clearance port 233, which connects the receiving cavity 232 and the support groove 13. The first clearance port 233 is used for the passage of the pipe of the valve control assembly 4. By integrating the valve control component 4 into the receiving cavity 232 in the second support base 23, the reliable installation of the valve control component 4 is facilitated, and the space utilization of the second support base 23 is improved, thereby reducing the space occupied by the valve control component 4 on other components of the water softener and making it easier to achieve a miniaturized design of the water softener. In addition, by setting the first clearance opening 233 in the third support part 231, the unobstructed passage of the valve control component 4 pipe and the efficient connection with the external water supply device are ensured, while maintaining the stable insertion of the third support part 231 and the support groove 13. While taking into account the compactness of the structure and the convenience of installation, the pipeline layout space is optimized, which significantly improves the overall reliability and maintenance convenience of the system.

[0048] See Figures 5-7 In one embodiment, the supporting shell 2 is further provided with a limiting base 24, which is connected to the connecting base 21. The limiting base 24 is located between the first supporting base 22 and the second supporting base 23. The limiting base 24 has a third limiting groove 241 and a second clearance opening 242. The third limiting groove 241 is arranged around the second clearance opening 242 and surrounds the upper outer wall of the resin tank 3. The third limiting groove 241 cooperates with the outer wall of the resin tank 3. The second clearance opening 242 penetrates the limiting base 24 both above and below, and the upper end of the resin tank 3 passes through the second clearance opening 242. The limiting base 24 and the connecting base 21 are integrally formed together. Because the limiting base 24 has a second clearance opening 242 that runs vertically through the top of the resin tank 3, it can avoid the top pipeline of the resin tank 3 and prevent the resin tank 3 from interfering with the valve control component 4. At the same time, the third limiting groove 241 surrounding the resin tank 3 directly cooperates with its outer wall, effectively limiting the upward and horizontal displacement of the resin tank 3. Since the limiting base 24 and the connecting base 21 are integrally set together, that is, the limiting base 24 and the connecting base 21 are integrally formed, the limiting base 24 can be connected to the connecting base 21 without additional connecting parts. This eliminates the need for connecting parts, significantly reduces the number of parts while ensuring installation stability, simplifies the structure, thereby reducing manufacturing costs and simplifying the maintenance process.

[0049] See Figure 6In one embodiment, the second support base 23 has a fourth limiting groove 234, which is located below the third limiting groove 241 and communicates with the third limiting groove 241. The fourth limiting groove 234 is arranged around a portion of the outer wall of the resin tank 3 and engages with the outer wall of the resin tank 3. By providing a fourth limiting groove 234 communicating with the third limiting groove 241 in the second support base 23, a double limiting structure is formed around the outer wall of the resin tank 3. This not only enhances the axial and radial fixing effect of the resin tank 3, preventing displacement and shaking, but also avoids additional fasteners through an integrated design, further simplifying the assembly process, improving structural stability, and reducing production costs.

[0050] In one embodiment, the first support portion 12 is erected on the side wall of the inner cavity 11, and the lower end of the first support portion 12 extends to the bottom wall of the inner cavity 11 to further enhance the structural support strength of the first support portion 12 and make the salt tank 1 less prone to deformation.

[0051] See Figure 4 In one embodiment, the bottom wall of the inner cavity 11 is further provided with a fourth support part 14, the fourth support part 14 having a first limiting groove 141, the first limiting groove 141 being adapted to the lower end of the resin tank 3.

[0052] The bottom wall of the inner cavity 11 is also provided with a fifth support part 15, which is connected to the fourth support part 14. The fifth support part 15 has a second limiting groove 151, which is used to fit with the lower end of the salt valve 41 in the valve control assembly 4. By setting the fourth support part 14 with the first limiting groove 141 on the bottom wall of the inner cavity 11 to accurately position the resin tank 3, and configuring the fifth support part 15 with the second limiting groove 151 connected to the fourth support part 14 to stably fit the salt valve 41, dual precise positioning and collaborative support are achieved, effectively improving the assembly accuracy, structural stability and system reliability of the components.

[0053] See Figure 4 In one embodiment, the bottom wall of the inner cavity 11 is further provided with a sixth support portion 16, which surrounds the fourth support portion 14. The sixth support portion 16 is spaced apart from the fourth support portion 14, and the height of the sixth support portion 16 is greater than that of the fourth support portion 14. The sixth support portion 16 abuts against the outer wall of the resin tank 3. Thus, the lower end of the resin tank 3 is precisely engaged by the first limiting groove 141 to achieve axial positioning. At the same time, the higher-sized sixth support portion 16 is arranged around the resin tank 3 at intervals to form a radial constraint ring, which abuts against the outer wall of the resin tank 3 to form a double limiting mechanism. This ensures the concentricity of the bottom of the resin tank 3 and enhances the resistance to lateral impact. The axial and radial limiting are optimized through the height difference layout.

[0054] See Figure 7This invention illustrates a preferred embodiment of a water softener, which includes the aforementioned housing.

[0055] This water softener, employing the aforementioned housing, also incorporates multiple spaced-apart first support portions 12 on the side wall of the inner cavity 11 of the brine tank 1. A connecting base 21 and a first support base 22 are added to the supporting shell 2. The connecting base 21 covers the top opening of the brine tank 1 for connection, while the first support base 22 extends into the inner cavity 11, abutting against the side wall of the brine tank 1 and connecting with the first support portions 12, thus forming a double-support structure. This design allows the supporting shell 2 and the side wall of the brine tank 1 to jointly bear the load through the cooperation of the first support base 22 and the first support portions 12, significantly reducing the load-bearing pressure on the brine tank 1. This allows for a reduction in the wall thickness of the brine tank 1 without compromising structural stability, thereby lowering material costs. Simultaneously, the bidirectional support structure restricts deformation of the side wall of the brine tank 1, preventing changes to the water level or structure within the brine tank 1, ensuring the normal brine intake of the brine valve 41, and further enhancing the overall structural rigidity and durability, extending the service life of the water softener.

[0056] In one embodiment, the water softener further includes:

[0057] The top cover 5 is located on the supporting shell 2 and covers the top of the supporting shell 2. The top of the resin tank 3 and the top of the valve control assembly 4 both extend into the top cover 5.
