[0037] Hard water can have many effects on daily life and household equipment. For example, it can reduce the washing effect, accumulate in the water pipes and reduce the water flow, damage the performance and life of the equipment, and cause skin problems. Therefore, people use water softening equipment to treat tap water in daily life. Using water softening equipment can effectively remove minerals in hard water, improve water quality, and enhance the quality of life. The treatment principle of water softening equipment is usually to remove calcium and magnesium ions in water through the process of ion exchange, thereby converting hard water into soft water.

[0038] Usually, water softeners use resin replacement for treatment. This resin is a polymer substance with a special structure and a positive charge on its surface. When hard water passes through the ion exchange resin, the calcium and magnesium ions in it will adsorb to the positive charge on the surface of the resin, replacing the original sodium ions on the resin. Usually, the resin particles are filled in a resin tank with a can-shaped structure. The water channel assembly is used to guide the water channel so that the water channel enters the resin tank and undergoes the above-mentioned replacement reaction before being discharged from the water channel assembly to complete the softening of the water quality.

[0039] In the related art, the water entering the resin tank through the water channel assembly has a certain water pressure. Since the resin tank is usually a straight cylindrical structure, when the water pressure is too high or the water flow speed is too fast, it is easy to cause the resin tank to rupture or explode, which reduces the durability of the product.

[0040] For problems in related technologies, see Figure 1-Figure 4 As shown, the utility model provides a resin tank of a water softener, which is used to be connected with a water channel assembly 200, including a tank body 100, the tank body 100 including a tank bottom 130, a tank body 120 and a tank top 110, the tank bottom 130 and the tank top 110 are connected through the tank body 120 to form a receiving cavity 1201, the tank top 110 has a first tank opening 1104 and a second tank opening 1105, the first tank opening 1104 is located on one side of the second tank opening 1105, and the first tank opening 1104 is used to communicate with the outer part of the receiving cavity 1201, the second tank opening 1105 is used to communicate with the central part of the receiving cavity 1201, and the central part and the outer part are separated by a side wall; wherein, at least one of the wall structure of the tank top 110 and the wall structure of the tank bottom 130 is constructed as a curved surface structure 140. Typically, water is guided by the water channel assembly 200 and enters the containing space through the first tank opening 1104 or the second tank opening 1105, and is output from the second tank opening 1105 or the first tank opening 1104. The water flow generates pressure on the tank body 100 during the flow. In this embodiment, at least one of the tank bottom 130 or the tank top 110 is configured as a curved surface structure 140. The setting of the curved surface structure 140 enables the spherical curved surface of the resin tank to evenly withstand pressure under the action of internal pressure, thereby reducing stress concentration and improving the strength and stability of the container. When the spherical curved surface structure is subjected to internal pressure, it can evenly withstand pressure, reduce deformation and stress concentration caused by deformation, and improve the ability to resist deformation.

[0041] It can be understood that in the present embodiment, water enters the resin tank through the first tank opening 1104 or the second tank opening 1105, and the water in the resin tank exerts pressure on the wall of the resin tank. Since the tank bottom 130 or the tank top 110 in the resin tank is a spherical arc surface structure, the water pressure in the tank body 100 can be more evenly stressed, reducing stress concentration, thereby making the overall structure of the tank body 100 more stable and having higher structural strength.

[0042] For specific settings, see Figure 4 As shown, the tank bottom 130 and the tank top 110 are both constructed as a curved surface structure 140, wherein the curved surface structure 140 of the tank bottom 130 is in direct contact with the water body, and after the water body is injected into the tank body 100, the curved surface structure 140 of the tank bottom 130 can reduce stress concentration, thereby improving the overall strength of the tank body 100. In this embodiment, the tank top 110 and the tank bottom 130 are both provided with the curved surface structure 140, which further increases the overall structural strength and makes the durability of the resin tank higher.

[0043] For specific applications, see Figure 2 As shown, the tank top 110 and the tank bottom 130 are integrally formed with the tank body 120, and during the integral forming process, the cambered surface structure 140 is provided on both the tank top 110 and the tank bottom 130. Of course, in some implementations, the tank top 110 and the tank bottom 130 can also be fixedly connected to the tank body 120, and in other embodiments, the tank top 110 and the tank body 120 are integrally formed, and the tank bottom 130 and the tank body 120 are fixedly connected to form.

[0044] In specific applications, the tank body 100 can be made of plastic, hard plastic or other materials, or, in other specific applications, the tank body 100 can also be made of metal. The tank top 110, the tank bottom 130 and the tank body 120 can be made of the same material. Of course, in other embodiments, the tank top 110, the tank bottom 130 and the tank body 120 can also be made of different materials.

[0045] According to an embodiment of the utility model, the tank bottom 130 is detachably connected to the tank body 120. The resin tank is used to fill resin particles, which need to be replaced regularly after long-term use. In this embodiment, the detachable connection between the tank bottom 130 and the tank body 120 can improve the preparation efficiency of the resin tank and reduce the difficulty of later maintenance.

[0046] It is understandable that the tank bottom 130 can be detachably connected to the tank body 120, and the detachable connection of the tank bottom 130 can facilitate the disassembly of the resin tank. For example, when the resin particles in the resin tank need to be replaced, the resin particles in the tank can be replaced by removing the tank bottom 130, and there is no need to remove and replace the entire resin tank, which reduces the difficulty of disassembly and maintenance.

[0047] In the specific setting, there is a curved surface structure 140 on the bottom 130 of the tank. After the water is input, the pressure-bearing capacity of the bottom 130 of the tank is greater. The setting of the curved surface structure 140 on the bottom 130 of the tank can effectively improve the stability of the tank structure, and improve the structural strength and pressure-bearing capacity of the tank.

[0048] It is understandable that the tank bottom 130 is detachably connected to the tank body 120, which allows the tank bottom 130 to be processed separately and then fixedly assembled. On the one hand, this can reduce transportation costs and risks during component transportation, and on the other hand, it can improve the production efficiency of the resin tank.

[0049] When specifically set, the tank bottom 130 includes a concave main wall portion 1301, and a connecting portion 1302 is provided around the outer edge of the main wall portion 1301, and the main wall portion 1301 is connected to the tank body 120 through the connecting portion 1302. When the water softener treats the water body, the size of the resin tank needs to consider the installation size, so the overall volume needs to be considered when the resin tank is set. In this embodiment, the main wall portion 1301 is set as a concave structure, and the concave structure can effectively increase the volume of the resin tank within a limited size space. Moreover, this structure can make the tank body more stably withstand pressure when impacted by external force, thereby reducing the risk of deformation or bursting of the tank body. In addition, the concave structure can also increase the contact area between the tank body and the ground, improve the supporting capacity of the tank body, and further enhance the stability of the tank body.

[0050] In a specific application, the concave portion of the main wall portion 1301 is located at the center of the tank body 100, see Figure 1 As shown, the lowest point of the concave part is approximately located at the center of the tank body 100, and the central tube 150 is disposed in the tank body 100, and the central tube is located at the center of the tank body 100. When performing soft water operations, the central tube 150 can completely discharge the softened water, thereby improving the processing efficiency.

[0051] It can be understood that a connecting portion 1302 is provided around the edge of the main wall portion 1301, and the main wall portion 1301 is detachably connected to the wall body through the setting of the connecting portion 1302, so that the main wall portion 1301 can be completely disassembled during disassembly, reducing the difficulty of disassembly.

[0052] In specific configuration, the connection portion 1302 can be configured as a snap-fit ​​structure. For example, a snap-fit ​​block can be provided on the edge of the main wall portion 1301, and a snap-fit ​​groove can be provided on the inner wall surface of the bottom of the can body 120. The snap-fit ​​block and the snap-fit ​​groove can be used to achieve snap-fit, thereby achieving a detachable connection between the two. Of course, the connection portion 1302 can also be configured as a threaded connection.

[0053] According to an embodiment provided by the utility model, at least one sealing ring is provided in the circumference of the connection portion 1302. When the tank bottom 130 is detachably connected to the tank body 120, the sealing of the connection between the two needs to be ensured. In this embodiment, a sealing ring is provided on the outer edge wall of the main wall portion 1301, and the sealing is achieved by the sealing ring, thereby improving the sealing of the connection between the tank body 120 and the tank bottom 130 and improving its sealing performance.

[0054] In the specific setting, there are two sealing rings on the connecting part 1302, and the two sealing rings are arranged at intervals along its axial direction. When the main wall part 1301 is connected, the two sealing rings extend into the can body 120, and the two sealing rings are squeezed between the inner wall surface of the can body 120 to achieve the airtight connection between the can body 120 and the main wall part 1301, thereby improving the stability of its closed structure.

[0055] In specific applications, see Figure 1 , Figure 4 As shown, the bottom of the main body wall has an outer convex edge, and the outer convex edge has bolt holes, and the corresponding bottom of the tank body 120 has multiple internal thread holes, so that when connecting, the main body wall 1301 is connected to the bottom of the tank body 120 by bolts, thereby realizing the connection of the main body wall 1301. When connecting, after the outer convex edge is fixed by bolts, a part of the entire main body wall extends into the bottom of the tank body 120, wherein the sealing ring is located in the part extending into the bottom of the tank body 120, and the sealing between the tank body 120 and the main body wall 1301 can be achieved by the extension of the sealing ring part, and the connection of the main body wall 1301 can be made tighter and more stable by bolt connection.

[0056] According to an embodiment provided by the utility model, the tank top 110 includes a platform portion 1101, the platform portion 1101 is connected to the tank body 120 and is located on the cross section of the tank body 120, the first tank opening 1104 and the second tank opening 1105 are both arranged on the platform portion 1101; and the platform portion 1101 has a raised edge portion 1102, and the edge portion 1102 gradually shrinks along the center of the platform portion 1101 to form a curved surface structure 140. The tank top 110 is connected to the waterway assembly 200, and the input or output of the waterway can be realized by connecting with the waterway assembly 200, that is, a tank opening needs to be set on the tank top 110, and multiple waterway circulations are realized by connecting the tank opening with the waterway component. In this embodiment, by setting the platform portion 1101, the platform portion 1101 makes the tank top 110 have a platform, and two tank openings are formed on the platform. The setting method on the platform can improve the accuracy of the tank opening and reduce the difficulty of the tank opening. The provision of the edge portion 1102 can improve the overall structural strength and stability of the tank.

[0057] It is understandable that when connecting with the water channel assembly 200, the opened tank mouth needs to be connected with the corresponding channel on the water channel component, which requires that the opening of the tank mouth has a certain position accuracy to avoid the tank body 100 being difficult to correspond to the channel on the water channel component after connection. In this embodiment, the position of the tank mouth is easier to determine when opening through the arrangement of the platform portion 1101, which reduces the difficulty of processing the tank mouth, and by arranging the edge portion 1102 on the edge of the platform portion 1101, the curved surface structure 140 is formed on the tank top 110 through the edge portion 1102, which can improve the structural strength of the tank top 110, so that it can withstand greater water pressure and water flow rate after the introduction of water.

[0058] In the specific configuration, the edge portion 1102 is non-continuous, that is, the edge portion 1102 of the platform portion 1101 is arranged at intervals, which can provide more space for the opening of the tank mouth and facilitate the setting of the tank mouth. The curved surface structure 140 of the outer wall of the edge portion 1102 improves the structural strength of the tank body 100, so that the tank top 110 has a higher structural strength, and can facilitate the opening of the tank mouth and facilitate the water to enter the tank body through the tank mouth.

[0059] For specific applications, see Figure 2 , Figure 3As shown, the water channel assembly 200 has a first flow channel 210 and a second flow channel 220, the first flow channel 210 has a first communication port 2101, the first communication port 2101 is connected to the first tank port 1104, and the second flow channel 220 has a second communication port 2201, the second communication port is connected to the second tank port 1105. When softening the water, it is necessary to isolate the central tube 150 part in the resin tank from the resin particle filling part of its peripheral part. Only in this way can the water discharged through the central tube 150 be treated water. Therefore, the central tube 150 and the peripheral part outside thereof are separated by a side wall structure. In this embodiment, the first tank port 1104 and the second tank port 1105 can be formed into a shape of a communication port by respectively setting a side wall structure, and then respectively realize the communication between the flow channels. In this way, it can be avoided that the two flow into each other when the water enters, thereby affecting the effect of water softening. Of course, it is also possible to set a side wall structure on one of them to achieve mutual isolation.

[0060] See also Figure 1 As shown, the platform portion 1101 has a first tank opening 1104 and a second tank opening 1105. The first tank opening 1104 has two through holes, which are located on both sides of the first tank opening 1104, and the two through holes are connected to the outer peripheral part of the resin tank, that is, the two through holes are connected to the resin filling part. The first tank opening 1104 is located at the center of the tank body 100 as a whole, and the first tank opening 1104 is connected to the central tank to realize the communication between the central pipe 150 and another flow channel of the waterway assembly 200.

[0061] In specific applications, at least a portion of the first tank port 1104 is located at the center of the tank body 100, so that the central tube 150 is located at the center of the tank body 100 after being connected to the first tank port 1104. The central tube 150 being located at the center can improve the performance of water treatment and improve the quality of regeneration.

[0062] It is understandable that the central tube 150 is located at the center of the tank body 100, and its outer part is filled with resin particles. When water quality treatment is performed, water enters through the first tank port 1104 and is replaced by the resin particles to achieve water softening, that is, hardness substances will be adsorbed by the resin particles, and the water will become soft water. If the position of the central tube 150 is offset, the water may have an uneven flow when passing through the resin particle filling area, thereby reducing the working efficiency of the resin bed and affecting the effect of softening water. In addition, when regenerating the water circuit, the water flow enters through the central tube 150. The setting of the central position of the central tube 150 allows the water flow to be in uniform contact with the resin filling part, avoiding uneven water flow passing through the resin particles, thereby affecting the regeneration and cleaning of the resin.

[0063] According to an embodiment provided by the utility model, see Figure 1 , Figure 2 As shown, the platform portion 1101 has an annular boss portion 1103, which extends in a direction perpendicular to the platform portion 1101, and the boss portion 1103 is used to form a second tank opening 1105. When water enters the resin tank, the water entering the central tube 150 and the water entering the outer peripheral portion of the resin tank should be relatively independent. In this embodiment, the second tank opening 1105 is surrounded by a raised side wall structure, which makes the resin tank relatively isolated from the first tank opening 1104 after being connected to the second tank opening 1105, so that when water quality treatment is performed, the water path will not flow into the second tank opening 1105 through the first tank opening 1104, thereby improving the water quality treatment quality.

[0064] For specific settings, see Figure 1 As shown, by setting an annular boss portion 1103, a second tank mouth 1105 is formed in the annular boss portion so that the second tank mouth 1105 as a whole is a long hole-like structure, and the top of the central tube 150 is connected to the second tank mouth 1105 and is interconnected, so that the fluid in the second flow channel 220 in the water channel component can enter the central tube 150 to realize the formation of a circulating water channel.

[0065] According to an embodiment provided by the utility model, Figure 1 As shown, there is a deflection angle a between the horizontal axis of the boss portion 1103 and the horizontal axis of the platform portion 1101. The opening position of the second flow channel 220 is opened off-center, which makes the distances between the second flow channels 220 and the central tube 150 differ greatly. In this embodiment, the difference between the water channels can be reduced by the inclined setting, so that the water channel distribution is more uniform and the treatment performance is improved.

[0066] Understandably, see Figure 1 As shown, there are two resin tanks under the same water channel component, and the two resin tanks are arranged side by side, and the water channel component has a first flow channel 210 and a second flow channel 220, and the water channel enters the outer part of the resin tank and the central tube 150 of the resin tank respectively through the two flow channels. In the opening of the second flow channel 220, the openings respectively connected to the resin tanks are arranged off-center, which makes the paths of the water channel entering the two central tubes respectively through the second flow channel 220 differ greatly, and the large difference in the paths will affect the distribution of the fluid entering the central tube 150 respectively from the flow channel, and further affect the performance of the entire water treatment. In this embodiment, by making the horizontal axis of the boss portion 1103 and the horizontal axis of the platform portion 1101 have a deflection angle a, the water channel path between the two openings and the central tube 150 can be shortened through the deflection angle, thereby achieving the improvement of product performance.

[0067] In the specific setting, the deflection angle a is 40 degrees. By limiting the specific angle, the water path can balance the distance of the water flowing to the two tanks after passing through the second flow channel 220, so as to achieve uniform flow of the two tanks, thereby improving the water quality treatment performance of the product.

[0068] According to an embodiment provided by the utility model, a reinforcing rib 1106 is provided at the bottom of the second tank opening 1105, and the reinforcing rib 1106 is located near the end of the second tank opening 1105. The second tank opening 1105 is a long through-hole structure as a whole, and the reinforcing rib 1106 is connected to the two ends of the second tank opening 1105, which can improve the structural strength of the second tank opening 1105, thereby improving the stability of the overall structure.

[0069] The utility model also provides a water softener, comprising: a water channel assembly 200 and a resin tank of the water softener provided in any of the above embodiments, wherein the water channel assembly 200 is arranged on one side of the axial direction of the resin tank; wherein the resin tank and the water channel assembly 200 are integrally formed. The integral forming method can improve the overall structural strength, thereby making the overall structural stability stronger and having a longer service life.
