Description

Technical Field

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

[0002] Commercially available water softeners mainly consist of a tank, a resin tank, and a valve control assembly. Their working principle involves the exchange of functional ions within the resin tank with calcium and magnesium ions in the water, thereby reducing the concentration of hardness ions. Once the resin becomes saturated, it needs to be regenerated using specialized brine within the tank, achieving recycling.

[0003] In existing water softeners, the bottom of the resin tank is installed at the bottom of the housing, while the top passes through the supporting shell and is locked in place by a fixing plate. However, due to the inevitable dimensional tolerances and deformations that occur during the manufacturing process of the housing, supporting shell, and resin tank, this connection method leads to the following problems: the resin tank is prone to loosening, failing to meet the requirements for fixed installation of the resin tank.

[0045] 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.

[0046] See Figures 1-7 This invention illustrates a preferred embodiment of a water softener, comprising:

[0047] Resin tank 1;

[0048] Salt tank 2 has a first receiving cavity 21, a mounting port 22 and a first limiting part 23. The first receiving cavity 21 is used to receive brine and resin tank 1. The mounting port 22 is located on the top of the salt tank 2 and communicates with the first receiving cavity 21. The first limiting part 23 is located on the bottom wall of the first receiving cavity 21 and cooperates with the lower part of the resin tank 1 to restrict the horizontal movement of the lower part of the resin tank 1.

[0049] A supporting shell 3 is mounted on the salt tank 2, covering the mounting opening 22. The supporting shell 3 has a second limiting part 31, which surrounds the upper part of the resin tank 1.

[0050] The flexible component 4 is sandwiched between the upper outer wall of the resin tank 1 and the second limiting part 31 to restrict the upper horizontal and vertical movement of the resin tank 1.

[0051] This utility model of a water softener restricts horizontal displacement of the resin tank 1 by setting a first limiting part 23 on the bottom wall of the brine tank 2 to cooperate with the lower part of the resin tank 1. At the same time, the upper part of the resin tank 1 is constrained by a second limiting part 31 of the supporting shell 3 combined with a flexible component 4, which restricts horizontal movement and buffers vertical vibration, thus achieving a stable installation of the resin tank 1 and avoiding loosening caused by processing errors or deformation. Secondly, the flexible component 4 can use its elastic deformation capacity to compensate for dimensional tolerances and assembly deformations between the resin tank 1, the brine tank 2, and the supporting shell 3, reducing the dependence on the processing precision of parts and improving assembly reliability and yield. At the same time, the damping characteristics of the flexible component 4 absorb vibration energy. This reduces stress concentration caused by rigid contact while ensuring structural reliability, enhancing structural adaptability and long-term stability. Furthermore, the flexible component 4 achieves self-fixation by being clamped between the second limiting part 31 and the resin tank 1, eliminating the need for additional connecting structures. This simplifies the overall design, reduces manufacturing costs, and improves installation convenience and assembly efficiency. Additionally, by suppressing the shaking of the resin tank 1, mechanical wear during operation is reduced, and fatigue damage to the connecting structure is decreased, thereby improving the overall durability of the water softener. Moreover, the stable fixation of the resin tank 1 prevents seal failure caused by shaking, ensuring the sealing of the brine regeneration process, preventing leakage, and improving the operational reliability of the water softener.

[0052] See Figures 3-4 In one embodiment, the flexible component 4 is arranged around the upper outer wall of the resin tank 1. In this way, the force can be evenly distributed by the flexible component 4 wrapping around the entire circumference, which can effectively buffer multi-directional vibration while enhancing radial constraint stability, and use its adaptive deformation characteristics to compensate for assembly tolerances in different directions, thereby achieving a more reliable flexible fixing effect.

[0053] In one embodiment, the flexible component 4 can specifically be a structure made of materials such as rubber, plastic, or sponge.

[0054] See Figures 6-7In one embodiment, the supporting shell 3 is further provided with a third limiting part 32, which is located between the first limiting part 23 and the second limiting part 31. The third limiting part 32 is arranged around a portion of the outer wall of the resin tank 1 and is adapted to the outer wall of the resin tank 1 to restrict the horizontal movement of the resin tank 1. In this way, the third limiting part 32 forms an intermediate positioning structure by surrounding a portion of the outer wall of the resin tank 1 and is adapted to and cooperates with the outer wall of the resin tank 1, establishing a multi-level constraint between the first limiting part 23 and the second limiting part 31, further suppressing the horizontal displacement of the resin tank 1, enhancing the overall fixation stability and vibration resistance, while maintaining the synergistic effect with the flexible component 4, forming a three-dimensional limiting system with graded buffering.

[0055] See Figure 3 and Figure 5 In one embodiment, the first limiting part 23 includes:

[0056] A first limiting ring 231 is disposed around the lower part of the resin tank 1. The first limiting ring 231 has a first limiting groove 2311, which is adapted to the lower bottom end of the resin tank 1.

[0057] The second limiting ring 232 surrounds the first limiting ring 231, and its height is greater than that of the first limiting ring 231. The second limiting ring 232 and the first limiting ring 231 are spaced apart, and the second limiting ring 232 abuts against the lower outer wall of the resin tank 1. That is, the first limiting part 23 has a double-ring nested structure. The first limiting groove 2311 of the first limiting ring 231 accurately engages with the bottom of the resin tank 1 to achieve axial positioning. At the same time, the higher-sized second limiting ring 232 is arranged around it at intervals to form a radial constraint ring, which abuts against the lower outer wall of the resin tank 1 to form a double limiting mechanism. This ensures the concentricity of the bottom of the resin tank 1 and enhances the resistance to lateral impact. The height difference layout achieves the coordinated optimization of axial and radial limiting.

[0058] In one embodiment, the number of second limiting rings 232 may be at least two, and the at least two second limiting rings 232 are arranged radially apart. Among two adjacent second limiting rings 232, the height dimension of the one closer to the first limiting ring 231 is smaller than the height dimension of the other. Each second limiting ring 232 abuts against the outer wall of the resin tank 1 to further enhance the installation stability of the resin tank 1.

[0059] See Figure 5In one embodiment, the first limiting portion 23 further includes a plurality of first protrusions 233, which are arranged sequentially around the first limiting ring 231. The first protrusions 233 connect the first limiting ring 231 and the second limiting ring 232. Thus, the plurality of first protrusions 233 form a uniformly distributed reinforcing connection structure, enhancing the overall structural strength while maintaining the spaced arrangement of the first limiting ring 231 and the second limiting ring 232. Furthermore, the discrete support design optimizes stress distribution, ensuring both flexible clamping of the resin tank 1 and improving the deformation resistance and long-term stability of the first limiting portion 23.

[0060] See Figure 5 In one embodiment, the second limiting ring 232 is spaced apart from the first limiting ring 231 to form a spacer cavity 234;

[0061] The side wall of the first limiting ring 231 has a first water inlet 2312, which passes through the first limiting ring 231 both above and below, and connects the first limiting groove 2311 and the spacer cavity 234.

[0062] The side wall of the second limiting ring 232 has a second water inlet 2321, which passes through the second limiting ring 232 both above and below, and the second water inlet 2321 connects the spacer cavity 234 and the first receiving cavity 21.

[0063] Each of the first protrusions 233 has a third water inlet 2331 on its sidewall, which connects to the spacer cavity 234. Thus, the second limiting ring 232 and the first limiting ring 231 are spaced apart to form the spacer cavity 234. Together with the first water inlet 2312 of the first limiting ring 231, the second water inlet 2321 of the second limiting ring 232, and the third water inlets 2331 of each of the first protrusions 233, they form a multi-level interconnected three-dimensional water flow channel network. This allows the brine to permeate and circulate evenly, ensuring uniform brine distribution during resin regeneration and preventing stagnant water. Furthermore, the buffering effect of the spacer cavity 234 reduces water flow impact, while maintaining the structural strength and positioning accuracy of the first limiting part 23, achieving synergistic optimization of fluid dynamics performance and mechanical stability.

[0064] See Figure 5 In one embodiment, the first limiting part 23 further includes at least two second protrusions 235 and at least two third protrusions 236. The second protrusions 235 connect the outer wall of the first limiting ring 231 to the bottom wall of the spacer cavity 234. The two second protrusions 235 are respectively placed on both sides of the first water outlet 2312 to form a bidirectional reinforced support structure, which improves the overall rigidity and deformation resistance of the first limiting ring 231 while maintaining the unobstructed flow of the first water outlet 2312.

[0065] The third protrusion 236 connects the outer wall of the second limiting ring 232 with the bottom wall of the first receiving cavity 21. The two third protrusions 236 are respectively placed on both sides of the second water outlet 2321 to form a bidirectional reinforced support structure, which improves the overall rigidity and deformation resistance of the second limiting ring 232 while maintaining the unobstructed flow of the second water outlet 2321.

[0066] See Figure 6 In one embodiment, the top of the second limiting part 31 is provided with a plurality of fourth protrusions 311, which are arranged sequentially around the vertical center line of the resin tank 1. By providing a plurality of fourth protrusions 311 arranged sequentially around the vertical center line of the resin tank 1 on the top of the second limiting part 31, a uniformly distributed top support structure is formed. This not only maintains the circumferential limiting effect on the upper part of the resin tank 1, but also optimizes the load distribution through multi-point support, enhancing the stability and anti-eccentric load capacity of the second limiting part 31, while ensuring the cooperative fixing effect between the second limiting part 31 and the flexible component 4.

[0067] See Figure 3 and Figure 6 In one embodiment, the supporting shell 3 is further provided with a first support portion 33. The first support portion 33 and the second limiting portion 31 are arranged side by side along the length direction of the salt tank 2. The first support portion 33 is located inside the first receiving cavity 21 and abuts against the side wall of the first receiving cavity 21. In this way, the abutment between the first support portion 33 and the inner wall of the first receiving cavity 21 forms a two-way support structure, which not only enhances the overall rigidity of the salt tank 2 and restricts the deformation of the salt tank 2, but also significantly enhances the overall rigidity of the supporting shell 3.

[0068] See Figure 3 and Figure 6 In one embodiment, the supporting shell 3 is further provided with a second support part 34. The second support part 34 and the first support part 33 are respectively placed on both sides of the second limiting part 31 along the length direction of the salt tank 2. At least a portion of the second support part 34 is located in the first receiving cavity 21. The side of the second support part 34 away from the first support part 33 abuts against the side of the salt tank 2. The second support part 34 is used to support the valve control assembly 5 of the water softener. Thus, the second support 34 provides stable support for the valve control assembly 5 within the first receiving cavity 21, making the layout of the core components more compact and reasonable. In addition, the second support 34 and the first support 33 work together to form a stable triangular support system, preventing lateral displacement of the resin tank 1 during operation. At the same time, since the second support 34 and the first support 33 are respectively placed on both sides of the second limiting part 31 along the length of the salt tank 2, the space utilization rate within the first receiving cavity 21 is optimized, making the positioning of each functional component more accurate and the installation more convenient. Furthermore, the addition of the second support 34 significantly improves the operational stability of the core components and extends the service life of the equipment without affecting the compactness of the equipment.

[0069] See Figure 6 In one embodiment, the second support 34 has a third receiving cavity 341 that extends through the top of the second support 34 and accommodates the lower part of the piston-type multi-way valve 52 in the valve control assembly 5. Thus, the third receiving cavity 341 provides precise positioning and stable support for the piston-type multi-way valve 52, effectively preventing vibration displacement during operation. Secondly, the through-type design of the third receiving cavity 341 facilitates the vertical installation and maintenance of the piston-type multi-way valve 52 and ensures smooth connection between the piston-type multi-way valve 52 and the upper assembly. Furthermore, this integrated support shell 3 structure achieves complete encapsulation and fixation of the piston-type multi-way valve 52 within a limited space, significantly improving the stability of the water softener's operation, while simplifying the assembly process, reducing production costs, and combining structural strength with operational convenience, making the internal layout of the water softener more compact and rational.

[0070] See Figures 6-7 In one embodiment, the supporting shell 3 is further provided with a fifth limiting part 35, which surrounds the second limiting part 31, the first supporting part 33 and the second supporting part 34. The fifth limiting part 35 is located on the top of the salt tank 2. In this way, the fifth limiting part 35 serves as a connector between the supporting shell 3 and the salt tank 2, which not only ensures the accurate positioning of the two but also enhances the overall structural stability.

[0071] See Figure 5 In one embodiment, the salt tank 2 is further provided with a fourth limiting part 24, which is located on the bottom wall of the first receiving cavity 21.

[0072] See Figure 6 The second limiting part 31 has a clearance opening 312, which extends through the second limiting part 31 both above and below, and the top of the resin tank 1 passes through the clearance opening 312.

[0073] See Figures 1-3 Water softeners also include:

[0074] Top cover 6 is disposed on the supporting middle shell 3 and covers the top of the supporting middle shell 3. Top cover 6 has a second receiving cavity 61, which receives the top of resin tank 1.

[0075] The second support portion 34 has a third receiving cavity 341, which is connected to the second receiving cavity 61;

[0076] Valve control assembly 5 includes:

[0077] Salt valve 51 is located in the first receiving cavity 21. The upper end of salt valve 51 is connected to the bottom of the second support part 34, and the lower end of salt valve 51 cooperates with the fourth limiting part 24 so that its horizontal movement is restricted by the fourth limiting part 24. Salt valve 51 is connected to the first receiving cavity 21.

[0078] Piston-type multi-way valve 52 is used to control the connection and disconnection between salt valve 51 and resin tank 1, and to control the connection and disconnection between resin tank 1 and external water supply device. The lower part of piston-type multi-way valve 52 is located in the third receiving cavity 341, and the upper part of piston-type multi-way valve 52 is located in the second receiving cavity 61. Thus, the upper end of the salt valve 51 is connected to the bottom of the second support part 34, and the fourth limiting part 24 on the bottom wall of the salt tank 2 cooperates with the lower end of the salt valve 51 to achieve horizontal limiting, thereby stably installing the salt valve 51 in the first receiving cavity 21 and ensuring its working reliability. Secondly, the top of the resin tank 1 is guided to extend to the second receiving cavity 61 of the top cover 6 by the avoidance port 312 of the second limiting part 31, and the salt valve 51 is fixed in the first receiving cavity 21. The piston-type multi-way valve 52 extends through the third receiving cavity 341 to the second receiving cavity 61, which not only maintains the water supply stability of the salt valve 51 and the operation independence of the piston-type multi-way valve 52, but also improves the space utilization through the layered receiving design, and finally achieves the compact and efficient collaborative assembly of the resin tank 1, valve control component 5 and box structure.

[0079] See Figure 5 In one embodiment, the fourth limiting part 24 has a second limiting groove and a fourth water outlet 241. The second limiting groove is adapted to the lower end of the salt valve 51, and the fourth water outlet 241 is located on the side wall of the fourth limiting part 24, connecting the second limiting groove and the first receiving cavity 21. Thus, precise positioning is achieved by adapting the second limiting groove of the fourth limiting part 24 to the lower end of the salt valve 51, while the fourth water outlet 241 on the side wall of the fourth limiting part 24 connects the second limiting groove and the first receiving cavity 21, effectively promoting the circulation of brine, avoiding stagnant water, thereby ensuring uniform brine distribution and improving the reliability of system operation.
