Description

Brine tank and water softener Technical Field

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

[0002] Water softeners on the market mainly consist of three core components: a brine tank, a resin tank, and a valve control assembly. Their working principle is to use the functional ions in the resin tank to exchange calcium and magnesium ions in the water to reduce water hardness. When the resin is saturated, it is regenerated by special brine in the brine tank, thereby realizing the recycling of the resin.

[0003] The existing brine tank structure of water softeners includes a brine inlet and a rotatable flip cover. The flip cover opens and closes the brine inlet to add brine through a flipping action. However, since the flip cover requires a certain flipping radius, the brine tank needs to reserve a large operating space during installation. This limits the installation flexibility of the water softener to some extent and increases the space occupation. In particular, it may affect the user experience in space-constrained installation environments. Summary of the Invention

Detailed Implementation

[0038] 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.

[0039] Referring to Figures 1-8, a preferred embodiment of the present invention is shown, which includes a brine tank. The brine tank comprises:

[0040] Box 1, Box 1 has an inner cavity 111 and a salt inlet 121, the inner cavity 111 is used to hold brine, and the salt inlet 121 is connected to the inner cavity 111;

[0041] Salt cap 2 is slidably mounted on the box body 1. Salt cap 2 has an open state and a closed state. In the open state, salt cap 2 is away from salt inlet 121 so that salt inlet 121 is open. In the closed state, salt cap 2 is placed on salt inlet 121 so that salt inlet 121 is closed. Salt inlet 121 can slide and switch between the open state and the closed state.

[0042] The first connecting component 3 is disposed on the housing 1, and is located on the side near the salt inlet 121; and

[0043] The second connecting component 4 is disposed on the salt cap 2. When the salt cap 2 is in the closed state, the second connecting component 4 is detachably connected to the first connecting component 3 to restrict the salt inlet 121 to the closed state.

[0044] This utility model's salt tank improves upon the traditional flip-top design by replacing it with a linearly sliding salt-adding cover 2. The salt-adding cover 2 opens and closes via lateral sliding, eliminating the need for a flip radius. This reduces the installation space required for the salt tank, making it particularly suitable for narrow spaces such as cabinets and niches, expanding the adaptability of the water softener's installation scenarios and making installation more flexible. Secondly, the sliding salt-adding cover 2 allows users to easily switch the open / closed state of the salt inlet 121 for rapid salt addition, improving ease of use. The closed state of the salt-adding cover 2 effectively seals the salt inlet 121, preventing foreign objects from entering or brine from evaporating, thus ensuring stable water quality. Simultaneously, salt addition... The design of the lid 2, which requires active operation to open, avoids accidental opening that could contaminate the tank 1 or cause water evaporation. Furthermore, the linear sliding opening and closing path is ergonomic, allowing users to add salt with one hand without needing to adjust the layout of items around the salt tank, significantly improving the user experience. Additionally, with the lid 2 closed, the first connecting component 3 and the second connecting component 4 are detachably connected. This ensures the lid 2 is securely closed, preventing accidental opening that could contaminate the tank 1 or cause brine evaporation, while retaining the convenient detachable feature for easy salting and equipment maintenance. This simple and reliable connection structure allows for easy fixing and releasing of the lid 2 without complex operations, greatly enhancing usability.

[0045] In one embodiment, both the first connecting component 3 and the second connecting component 4 are magnetic components, allowing them to be connected together magnetically. This magnetic connection design ensures that the first connecting component 3 and the second connecting component 4 automatically adhere and lock when the salt cap 2 is closed, guaranteeing reliable sealing and preventing contamination of the container 1 and salt water evaporation. It also allows for easy one-handed opening and closing. The magnetic connection eliminates the need for complex structures like mechanical clips, simplifying the opening and closing action and significantly improving the user experience. It also avoids the problems of easy wear and salt jamming associated with traditional mechanical connectors, resulting in a longer service life and lower maintenance costs. Furthermore, this design facilitates quick disassembly, cleaning, and maintenance. The magnetic force can be adjusted as needed, ensuring both a secure closure and smooth opening and closing. The overall structure is simple, aesthetically pleasing, and highly practical.

[0046] Of course, in other embodiments, the first connecting part 3 and the second connecting part 4 can both be snap-fit ​​structures, so that the first connecting part 3 and the second connecting part 4 are connected together by snap-fit, which can also reliably keep the salt cap 2 in the closed state.

[0047] Referring to Figures 2-3, in one embodiment, the box body 1 is provided with at least two guide portions 122, which are respectively placed on both sides of the salt inlet 121 along the sliding direction of the salt cover 2;

[0048] The salt cap 2 has at least two guide grooves 21, each guide groove 21 being slidably engaged with a corresponding guide part 122. By providing a precise sliding engagement structure between the guide parts 122 on both sides of the salt inlet 121 of the housing 1 and the guide grooves 21 of the salt cap 2, smooth guidance and precise positioning during the opening and closing process of the salt cap 2 are achieved, effectively preventing the salt cap 2 from shifting or jamming. The dual-guide design ensures balanced force on the salt cap 2 during sliding, avoiding one-sided wear and significantly extending its service life. The engagement gap between the guide part 122 and the guide groove 21 can be precisely controlled, ensuring smooth sliding while effectively preventing salt particles from entering and affecting sliding performance. This structure is simple and reliable, achieving stable sliding of the salt cap 2 without additional complex mechanisms, while also facilitating disassembly and maintenance. The overall design balances operational reliability, durability, and ease of maintenance.

[0049] In one embodiment, when the salt cap 2 is in the closed state, the salt cap 2 covers the guide portion 122 to hide the guide portion 122 and the guide groove 21, so that the appearance of the water softener remains flat and the exposed guide portion 122 is avoided from affecting the aesthetics.

[0050] Referring to Figures 3 and 4, in one embodiment, the salt cap 2 has a gripping part 22, a cavity 23, and an operating port. The gripping part 22 is located inside the cavity 23, and the operating port communicates with the cavity 23. The operating port is used for the hand to reach into the cavity 23 to grasp the gripping part 22, thereby gripping the salt cap 2. In this way, the hand can reach in and grasp the salt cap 2 through the operating port, which maintains the flatness of the appearance of the salt cap 2 and provides a stable point of force application, making the sliding operation of the salt cap 2 more effortless and precise. At the same time, it avoids spatial interference caused by protruding parts, which is especially suitable for one-handed operation in confined installation environments, taking into account both ergonomics and space utilization.

[0051] Referring to Figures 1-5, in one embodiment, the housing 1 includes:

[0052] The box body 11 has an inner cavity 111 and a mounting port. The inner cavity 111 is also used to accommodate the resin tank 5. The mounting port is located on the top of the box body 11 and communicates with the inner cavity 111. The mounting port is used for the resin tank 5 to enter and exit the inner cavity 111.

[0053] The cover body 12 is located on top of the tank body 11, covering the installation port and having a salt filling port 121. Thus, by integrating the inner cavity 111 and the top installation port of the tank body 11, the resin tank 5 achieves convenient loading and unloading as well as brine containment. The cover body 12 seals the installation port and integrates the salt filling port 121, forming a compact and closed structure. This simplifies the production process, reduces manufacturing costs, improves installation and maintenance convenience, optimizes the spatial layout, makes the equipment structure more compact, significantly improves space utilization, and enhances the overall sealing and stability of the structure.

[0054] In one embodiment, the main body 11 of the box has a first limiting groove 112, which is located on the bottom wall of the inner cavity 111. The first limiting groove 112 is used to cooperate with the lower end of the resin tank 5 to restrict the lateral movement of the lower end of the resin tank 5.

[0055] Box 1 also includes:

[0056] A supporting shell 13 is provided on the main body 11 of the box. The supporting shell 13 covers the installation port and supports the cover body 12. The top of the supporting shell 13 is covered by the cover body 12. The supporting shell 13 has a salt filling channel 1311 and a second limiting groove 132. The salt filling channel 1311 connects the salt filling port 121 and the inner cavity 111. The second limiting groove 132 is used to cooperate with the upper end of the resin tank 5 to restrict the lateral and vertical movement of the upper end of the resin tank 5. Thus, the resin tank 5 is positioned bidirectionally by the coordinated upper and lower cooperation of the first limiting groove 112 at the bottom of the main body 11 and the second limiting groove 132 of the supporting shell 13, which restricts lateral displacement and controls vertical movement, ensuring the operational stability of the resin tank 5. In addition, the supporting shell 13, as an intermediate connector, simultaneously undertakes the functions of guiding the salt filling channel 1311 and supporting the cover body 12, forming a multi-layer limiting structure. This simplifies the assembly process while improving the overall structural strength, effectively preventing the resin tank 5 from shaking, and achieving the dual effects of efficient space utilization and precise component positioning.

[0057] Referring to Figures 4 and 5, in one embodiment, the cap body 12 has a first receiving cavity 123, and the supporting middle shell 13 has a clearance opening 133 and a second receiving cavity 1341. The clearance opening 133 connects the second limiting groove 132 and the first receiving cavity 123, and is used for the top of the resin tank 5 to pass through. The second receiving cavity 1341 is used to accommodate the lower part of the piston-type multi-way valve 61 in the valve control assembly 6, and the first receiving cavity 123 is used to accommodate the top of the resin tank 5 and the upper part of the piston-type multi-way valve 61. Thus, through the layered structural design of the first receiving cavity 123 of the cap body 12 and the second receiving cavity 1341 of the supporting middle shell 13, the top positioning of the resin tank 5 and the upper and lower layered assembly of the piston-type multi-way valve 61 can be achieved simultaneously in a limited space. The clearance opening 133 precisely guides the resin tank 5 through the path, forming a compact three-dimensional layout structure, which not only ensures the stability of the installation of each component but also optimizes the utilization of internal space, simplifies the assembly process, and improves the integration and maintenance convenience of the overall structure.

[0058] Referring to Figures 4 and 7-8, in one embodiment, the supporting shell 13 is provided with a first supporting base 131 and a second supporting base 134. The first supporting base 131 is located in the inner cavity 111, and the outer wall of the first supporting base 131 abuts against the side wall of the inner cavity 111. The first supporting base 131 has a salt filling channel 1311. A portion of the second supporting base 134 is located in the inner cavity 111, and the side of the second supporting base 134 away from the first supporting base 131 abuts against the side wall of the main body 11. The second supporting base 134 has a second receiving cavity 1341. Thus, the tight fit between the first support base 131 and the inner cavity 111 sidewall of the box body 1 achieves a stable structural support, effectively preventing deformation of the box body 11. At the same time, the integration of the salt filling channel 1311 on the first support base 131 improves the space utilization of the first support base 131 and avoids the salt filling channel 1311 occupying other space of the supporting shell 13. The second support base 134 abuts against the box body 11 through its sidewall, forming a cooperative force-bearing structure with the first support base 131, which can further enhance the structural stability of the supporting shell 13 and the box body 11. Its built-in second accommodating cavity 1341 efficiently accommodates the valve control component 6 in a limited space. The dual support base design enhances the overall structural rigidity while realizing functional zoning, optimizing space utilization and improving assembly accuracy and structural stability.

[0059] Referring to Figures 4 and 7, in one embodiment, the sidewall of the first support base 131 is provided with a plurality of first support protrusions 1312. These protrusions are arranged at intervals around the vertical centerline of the first support base 131, and each protrusion abuts against the sidewall of the inner cavity 111. Thus, by providing a plurality of spaced-apart first support protrusions 1312 on the first support base 131 that abut against the sidewall of the inner cavity 111 of the box body 11, a multi-point uniform support structure is formed. This enhances the overall structural stability and improves the resistance to deformation, while ensuring precise alignment of the first support base 131 and optimizing the stress distribution, significantly improving assembly reliability and long-term durability.

[0060] Referring to Figure 6, in one embodiment, the box body 11 is provided with a plurality of second support protrusions 115, all of which are located on the side wall of the inner cavity 111. Thus, the provision of the second support protrusions 115 increases the structural strength of the box body 11 and effectively resists deformation of the box body 11.

[0061] Referring to Figures 6 and 7, in one embodiment, the first support protrusion 1312 has a slot 13121, and the second support protrusion 115 has a snap-fit ​​protrusion 1151. The snap-fit ​​protrusion 1151 is adapted to the slot 13121. Thus, the slot 13121 and the snap-fit ​​protrusion 1151 cooperate to form a locking structure, which not only enhances the connection stability between the first support base 131 and the inner cavity 111 of the box body 11, but also achieves rapid and accurate positioning. At the same time, it optimizes the force distribution and effectively improves the impact resistance and long-term reliability of the overall structure.

[0062] Referring to Figures 4 and 5, in one embodiment, the side wall of the housing body 11 has a support groove 113, and the second support base 134 has a support part 1342 on the side opposite to the first support base 131. The support part 1342 is inserted into the support groove 113. By providing a support groove 113 on the side wall of the housing body 11 and correspondingly providing a support part 1342 that can be inserted into the support groove 113 on the second support base 134, a mechanical interlocking structure is formed. This not only enhances the connection strength and stability between the support shell 13 and the housing body 11, effectively preventing relative displacement between components, but also achieves precise positioning and assembly guidance through the cooperation of the support groove 113 and the support part 1342, 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 6 is evenly distributed to the side wall of the housing body 11 through the support part 1342, significantly reducing the risk of structural deformation. While improving product durability, it maintains structural compactness and production economy.

[0063] Referring to Figure 7, in one embodiment, the second support base 134 further has a third limiting groove 1343, which is located below the second limiting groove 132 and communicates with it. The third limiting groove 1343 is arranged around a portion of the outer wall of the resin tank 5 and engages with the outer wall of the resin tank 5. By providing a third limiting groove 1343 communicating with the second limiting groove 132 in the second support base 134, a double limiting structure is formed around the outer wall of the resin tank 5. This not only enhances the axial and radial fixing effect of the resin tank 5, preventing displacement and shaking, but also avoids additional fasteners through integrated design, further simplifying the assembly process, improving structural stability, and reducing production costs.

[0064] Referring to Figure 6, in one embodiment, the tank body 11 also has a fourth limiting groove 114, which is located on the bottom wall of the inner cavity 111. The fourth limiting groove 114 is adapted to the lower end of the salt valve 62 in the valve control assembly 6, and the upper end of the salt valve 62 is connected to the second support base 134 to reliably fix the salt valve 62 and ensure the operational reliability of the salt valve 62. The salt valve 62 communicates with the inner cavity 111, and the piston-type multi-way valve 61 in the valve control assembly 6 is used to control the communication between the salt valve 62 and the resin tank 5 and the communication between the resin tank 5 and the external water supply device, so as to ensure that the resin tank 5 can be regenerated and that the resin tank 5 can soften hard water.

[0065] A preferred embodiment of this utility model provides a water softener, including the salt tank described above.

[0066] This utility model of a water softener, by adopting the aforementioned salt tank, also improves upon the traditional flip-top design by replacing it with a linearly sliding salt filling cover 2. The salt filling cover 2 opens and closes via lateral sliding, eliminating the need for a flip radius. This reduces the installation space required for the salt tank, making it particularly suitable for narrow spaces such as cabinets and niches, thus expanding the water softener's adaptability to various installation scenarios and making installation more flexible. Secondly, by setting up the sliding salt filling cover 2, users can easily switch the open / closed state of the salt filling port 121 for rapid salt addition, improving ease of use. Furthermore, the closed state of the salt filling cover 2 effectively seals the salt filling port 121, preventing foreign objects from entering or brine from evaporating, thereby ensuring stable water quality. The design of the salt cap 2, which requires active operation to open, prevents accidental opening from contaminating the tank 1 or causing water evaporation. Furthermore, the linear sliding opening and closing path is ergonomic, allowing users to add salt with one hand without needing to adjust the layout of items around the salt tank, significantly improving the user experience. Additionally, when the salt cap 2 is closed, the first connecting component 3 and the second connecting component 4 are detachably connected. This ensures the salt cap 2 is securely closed, preventing accidental opening from contaminating the tank 1 or causing brine evaporation, while retaining the convenient detachable feature for easy salting and equipment maintenance. This simple and reliable connection structure allows for the fixing and releasing of the salt cap 2 without complex operations, greatly enhancing ease of use.
