[0035] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, the water softener provided by the utility model mainly includes: a salt box 1 and an anti-overflow structure. The salt box 1 is arranged at the front side of the water softener, and an overflow port is arranged at the back side of the salt box 1; the anti-overflow structure includes an overflow pipe 2 and a joint assembly 3, the overflow pipe 2 is arranged at the back side of the salt box 1 along the length direction of the water softener, and the first end of the overflow pipe 2 is connected to the overflow port of the salt box 1; the joint assembly 3 is arranged on the rear cover plate 4 of the water softener, and is connected to the second end of the overflow pipe 2.

[0036] The embodiment of the utility model is aimed at the shortcomings of traditional large-volume water softeners in salt tank water level control, especially the overflow problem that may occur when the water level is high. To solve this problem, the embodiment of the utility model provides an improved water softener structure design:

[0037] 1. Salt box design: The salt box 1 is cleverly set at the front side of the water softener to facilitate users to add salt, and an overflow port is added on the back side of the salt box 1. When the water level in the salt box 1 is too high, the excess water can be discharged through this overflow port to avoid water overflowing directly from the top of the salt box 1 and causing moisture and pollution inside the equipment or the surrounding environment.

[0038] 2. Overflow pipe arrangement: An overflow pipe 2 is installed along the length of the water softener, and the first end of the overflow pipe 2 is connected to the overflow port of the salt tank 1. This design can guide the possible overflowing water to a safe drainage position through the pipe, ensure the stability of the liquid level in the salt tank 1, and prevent the disordered discharge of water from affecting the normal operation and service life of the water softener.

[0039] 3. Joint assembly: A joint assembly 3 is provided on the rear cover plate 4 of the water softener, which is connected to the second end of the overflow pipe 2 and is used to guide the overflowed water to the sewer or other suitable location for discharge, thereby ensuring the sealing and effectiveness of the entire anti-overflow structure.

[0040] 4. Whole machine optimization: By integrating the anti-overflow structure and reasonably arranging the overflow pipe 2 horizontally from front to back, the thickness of the water softener can be reduced, which is more conducive to miniaturization design and can adapt to various narrow installation spaces, thereby improving the user's installation flexibility and usage experience.

[0041] Therefore, the water softener of the embodiment of the utility model solves the potential overflow risk of the salt box of the water softener and realizes the miniaturization of the equipment through the design of the integrated overflow prevention structure.

[0042] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, the water softener further comprises: a resin tank 5, which is arranged inside the water softener and arranged side by side on the back side of the salt box 1 along the length direction of the water softener.

[0043] Specifically, the resin tank 5, as one of the core components of the water softener, is placed inside the water softener and arranged side by side on the back side of the salt box 1 along the length direction of the water softener. This parallel layout can make full use of the internal space of the water softener and avoid the increase in overall thickness caused by the stacking of components. By arranging the resin tank 5 and the salt box 1 side by side, rather than vertically or cross-stacked, the entire water softener can effectively reduce the thickness of the equipment while maintaining functional integrity, meet the requirements of ultra-thin design, and is particularly suitable for environments with limited installation space. In addition, the resin tank 5 and the salt box 1 are compactly arranged side by side, which reduces the complexity and length of the internal pipe connection, which is not only conducive to improving the water flow exchange efficiency, but also reduces the equipment manufacturing cost and potential failure rate, further improving the product's user experience and durability.

[0044] Therefore, the embodiment of the utility model achieves the goal of reducing the thickness and miniaturizing the water softener by cleverly arranging the salt box 1 and the resin tank 5 side by side, thereby improving its adaptability in narrow spaces and convenience for users.

[0045] According to an embodiment of the present invention, the resin tank 5 includes at least two tank bodies, which are arranged side by side along the length direction of the water softener.

[0046] It is understandable that the tank body can be a separate component, that is, the water softener has multiple independent resin tanks 5 arranged side by side; of course, the tank body can also be an integrally formed component, that is, one resin tank 5 has multiple tank bodies arranged side by side.

[0047] For example, two resin tanks 5 are provided, and the inlets of the two resin tanks 5 are connected, and the outlets of the two resin tanks 5 are connected, so that the resin tanks 5 are provided in parallel.

[0048] Specifically, a large-volume resin tank 5 can be divided into a plurality of small-volume resin tanks 5 arranged in parallel, which can more efficiently utilize the limited space resources inside the water softener. This method can further reduce the thickness of the entire machine.

[0049] Furthermore, the design of multiple resin tanks makes the maintenance and replacement of a single resin tank 5 more convenient. There is no need to disassemble the entire device, and only the resin tank 5 that needs to be replaced or maintained needs to be operated, which reduces the difficulty and cost of maintenance.

[0050] In particular, if multiple resin tanks 5 working in parallel are used, when one of the resin tanks 5 reaches a saturated state, other unsaturated resin tanks 5 can continue to perform ion exchange work, thereby ensuring that the water softener can continue to provide softened water and improving the stability and reliability of the system.

[0051] In addition, according to actual needs, by adjusting the working order of each resin tank 5 or configuring resin tanks 5 with different capacities, the water flow rate and softening effect can be flexibly adjusted to achieve precise control of the water softening process.

[0052] Therefore, the embodiment of the utility model not only realizes the ultra-thin transformation of the water softener through the reasonable design of the number and layout of the resin tanks 5, but also improves its functionality, ease of use and work efficiency, and significantly improves the user experience.

[0053] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, the resin tank 5 is cylindrical in shape, and a plurality of reinforcing rib plates 6 are arranged at intervals along the height direction in the gap between two adjacent resin tanks 5 .

[0054] Specifically, by arranging reinforcing ribs 6 in the gaps between adjacent resin tanks 5, the space utilization efficiency is further improved, which is conducive to the miniaturization of the entire machine. The added reinforcing ribs 6 can disperse and withstand the stress generated during the operation of the equipment without affecting the function of the resin tank 5, thereby reducing the potential risk of structural damage caused by vibration or pressure changes and enhancing the rigidity and stability of the entire water softener structure.

[0055] According to an embodiment of the present invention, the reinforcing rib plate 6 is arranged to be tilted downward along the direction from the inside to the outside of the gap between the two resin tanks 5, and the bottom shell 7 of the water softener is a water collecting box connected to the drainage pipe.

[0056] Specifically, the inclined setting of the reinforcing rib plate 6 helps to form a natural water flow guiding path. When water or waste water generated during the cleaning process enters the gap between the two resin tanks 5, it can flow along the inclined reinforcing rib plate 6 to the water collecting box at the bottom of the equipment, and then be discharged through the drain pipe, which can prevent water from accumulating in the gap between the resin tanks 5, thereby reducing the risk of internal corrosion of the equipment and component failure due to long-term water accumulation.

[0057] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, the overflow pipe 2 is detachably connected to the side of the resin tank 5 .

[0058] Specifically, when the resin tank 5 or the overflow pipe 2 fails and needs to be repaired or cleaned, the detachable connection mode facilitates quick disassembly without the need to disassemble the water softener as a whole, which greatly simplifies the installation and replacement steps of the internal components of the water softener and improves the equipment installation efficiency.

[0059] Furthermore, since the overflow pipe 2 can be arranged in close contact with the side of the resin tank 5, it helps to further reduce the overall size of the water softener and achieve an ultra-thin design.

[0060] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, a buckle 8 is provided on the side of the resin tank 5 , and the buckle 8 is formed with a slot, and the overflow pipe 2 is snapped into the slot.

[0061] In this embodiment of the utility model, the side of the resin tank 5 is designed with a snap-fit ​​structure, and these snap-fits 8 form a snap-fit ​​groove. In this way, the overflow pipe 2 is snap-fitted with the side of the resin tank 5, which is specifically manifested as follows:

[0062] 1. Buckle design: The buckle design makes the assembly relationship between the resin tank 5 and the overflow pipe 2 simpler and faster, without the need for complicated fixing tools or threaded connections. The installation can be completed by simply aligning the position and pressing lightly, thereby improving production assembly efficiency.

[0063] 2. Stability and sealing: After the overflow pipe 2 is inserted into the slot of the buckle 8, it can ensure that the overflow pipe 2 is firmly fixed on the resin tank 5, effectively preventing loosening or leakage caused by water flow impact or other factors, thereby ensuring the stability of the equipment during operation and the overall sealing performance.

[0064] 3. Easy disassembly: When the overflow pipe 2 needs to be replaced or the resin tank 5 needs to be maintained, due to the snap-on connection, the user can easily pull out the overflow pipe 2 from the snap 8 on the resin tank 5 without the need for additional tools, which greatly simplifies the repair and maintenance process.

[0065] 4. Thickness control: The snap-on structure takes up little space. This design helps to keep the overall thickness of the water softener within a smaller range, which is in line with the ultra-thin design concept.

[0066] Therefore, this embodiment not only realizes convenient assembly and disassembly between components through the snap fit between the buckle 8 on the side of the resin tank 5 and the overflow pipe 2, but also effectively promotes the miniaturization and functional optimization of the water softener, thereby improving the user experience.

[0067] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, at least two buckles 8 are provided along the length direction of the overflow pipe 2 .

[0068] With such a design, when the overflow pipe 2 is connected with the buckle 8, it can provide multi-point support and fixation, thereby greatly enhancing the stability of the overflow pipe 2, effectively preventing loosening caused by water flow impact or equipment vibration, etc., improving the overall sealing performance, preventing water from leaking from the connection, and ensuring the normal operation of the internal system of the water softener. In addition, multiple buckles 8 can disperse pressure, so that the overflow pipe 2 is more evenly stressed after installation, reducing local stress concentration, extending the service life of components, and ensuring the safety of the equipment during operation.

[0069] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, along the height direction of the salt box 1, at least two overflow pipes 2 are arranged side by side up and down.

[0070] Specifically, by setting up multiple overflow pipes 2, the overflow efficiency of the salt box 1 can be significantly improved. When the water level in the salt box 1 is too high, multiple overflow pipes 2 can discharge excess water at the same time, avoiding the problem that a single pipe may overflow due to blockage or insufficient flow. That is, multiple overflow pipes 2 provide a safety redundancy mechanism. Even if one of them fails or is blocked, the other overflow pipes 2 can still work normally, ensuring that the liquid level in the salt box 1 is always within a safe range and preventing excessive water from causing damage to the equipment. In addition, the design of multiple overflow pipes 2 helps to disperse the water pressure, making the pressure inside the salt box 1 more balanced, reducing the local stress concentration caused by water flow impact, and helping to extend the service life of the salt box 1 and the anti-overflow structure.

[0071] In a specific example, two overflow pipes 2 are arranged side by side in the upper and lower parts, two resin tanks 5 are arranged side by side in the front and back parts, and two buckles 8 are arranged in the upper and lower parts on each resin tank 5, and the upper and lower buckles 8 of each resin tank 5 are arranged in a staggered manner, and each overflow pipe 2 is buckled on two buckles 8 at the same height. Such a design can facilitate the stable assembly of the overflow pipe 2.

[0072] According to one embodiment of the utility model, referring to Figure 1 and Figure 2 As shown, the joint assembly 3 mainly includes: an adapter 301 and a quick connector 302. The adapter 301 is disposed on the rear cover plate 4 of the water softener and connected to the second end of the overflow pipe 2; the quick connector 302 is connected to the adapter 301.

[0073] Specifically, the quick connector 302 can be an elbow connector, and the quick connector 302 can be connected to one end of the drain pipe, and the other end of the drain pipe is fixed in the sewer pipe, so that a complete overflow pipe from the overflow port of the salt tank 1 inside the water softener to the external drainage is constructed. The adapter 301 is used as an intermediate transition component, which is connected to the second end of the overflow pipe 2 and the quick connector 302 respectively, and plays a bridge role to ensure that the water flow can flow smoothly from the salt tank 1 through the overflow pipe 2 into the sewer.

[0074] According to one embodiment of the utility model, referring to Figure 2 As shown, a liquid outlet pipe 9 is provided on the back side of the salt box 1, and the liquid outlet pipe 9 is provided with an overflow port; and both ends of the overflow pipe 2 are respectively interference-fitted with the liquid outlet pipe 9 and the adapter 301.

[0075] In this embodiment of the utility model, a liquid outlet pipe 9 is installed on the back side of the salt box 1, and an overflow port is specially provided on the liquid outlet pipe 9. When the liquid level inside the salt box 1 rises to a set threshold, the excess liquid will flow out through the overflow port, thereby achieving effective control and protection of the water level inside the salt box 1. In addition, the two ends of the overflow pipe 2 in the design are respectively connected to the liquid outlet pipe 9 and the adapter 301 by interference fit, wherein:

[0076] The first end of the overflow pipe 2 is interference fit with the overflow port on the liquid outlet pipe 9 on the back side of the salt box 1. The connection between the two is very tight without obvious gap to prevent water leakage and ensure that under the action of the internal pressure of the salt box 1, the overflow can quickly and smoothly enter the overflow pipe 2 through the overflow port.

[0077] The second end of the overflow pipe 2 is also connected to the adapter 301 by an interference fit. This tight connection not only improves the sealing performance, but also ensures the stability of the entire anti-overflow structure during operation, so that the overflowed liquid can be further guided to the external sewer through the adapter 301.

[0078] In this way, the embodiment of the utility model effectively solves the overflow problem caused by excessive water level in the salt box of the traditional water softener, while also improving the overall safety performance and user experience of the equipment, simplifying the installation process, and enhancing the reliability of the product.

[0079] In addition, the overflow pipe 2 is a hose, and a fastener or a clamp is provided at the hose interface, which can ensure a close fit with the connection parts such as the liquid outlet pipe 9 and the adapter 301 of the salt box 1, and effectively prevent the occurrence of water leakage.

[0080] It is understandable that the hose material is soft and has good elasticity. It can be flexibly bent and arranged according to the installation space and the internal structure of the equipment to adapt to different installation environments and needs. The hose can absorb and reduce the impact of water flow impact or equipment vibration, reduce noise, and protect connecting parts from excessive stress damage.

[0081] According to an embodiment of the present invention, the adapter 301 is a three-way adapter.

[0082] Specifically, the second ends of the two overflow pipes 2 are respectively connected to the two ports of the three-way adapter, and the other port of the three-way adapter is connected to the quick connector 302 .

[0083] The water softener provided by the utility model is described below in conjunction with a specific example, which generally includes:

[0084] The function of the overflow pipe 2 is to discharge the excess water in the salt box 1 when the water level in the salt box 1 keeps rising and is higher than the overflow pipe 2, so as to prevent the water in the salt box 1 from overflowing into the machine, thereby avoiding contamination of the user's kitchen.

[0085] During assembly, one end of the two overflow pipes 2 is fixed on the two liquid outlet pipes 9 of the salt box 1 by interference fit, and the other end is connected to the two ports of the three-way adapter on the rear cover plate 4 by interference fit. In the middle position, the overflow pipe 2 is restricted from flowing outward through the buckle 8 structure on the side of the resin tank 5. The elbow is connected to the other end of the three-way adapter. The user only needs to install one end of the PE drainage pipe on the elbow and fix the other end in the user's sewer pipe, so as to form a complete overflow pipeline and realize overflow drainage.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
