Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a water distributor component and water softening equipment. Background Art

[0002] A water softener is a water purification device that reduces the hardness of water and improves the taste and feel of water. Existing water softeners are mainly divided into two types according to the water purification principle: the first type is a water softener that uses ion exchange method, which mainly removes calcium ions and magnesium ions in water through ion exchange resin; the second type is a water softener that uses physical packaging method, which mainly uses nanocrystalline high-energy polymer spheres to package calcium ions, magnesium ions, bicarbonate, etc. in the water to produce water-insoluble nano-crystals, thereby inhibiting the formation of scale.

[0003] The resin tank of a water softener using the ion exchange method usually includes a tank body and a water distributor assembly arranged in the tank body. A storage space for containing resin is formed between the tank body and the water distributor assembly. The storage space is filled with resin. A water inlet joint and a water outlet joint are provided on the tank body. The water inlet joint is connected to the water source, and the water outlet joint is connected to the external water outlet. The water in the water source flows into the tank body from the water inlet joint, is distributed by the water distributor assembly, and then is softened and purified by the resin, and then flows out from the water outlet joint to the external water outlet for users to take. In the prior art, the water distributor assembly includes a central tube and upper and lower water distributors, which are respectively mounted on both ends of the central tube to achieve uniform water distribution within the tank. The steps for assembling the resin tank are: first, the upper water distributor is mounted on the top of the central tube, then the upper water distributor and central tube assembly is installed in the tank, the tank is filled with resin, and then the lower water distributor is mounted on the bottom of the central tube.

[0042] Figure 1 FIG. 2 shows a cross-sectional schematic diagram of the water softening device provided in this embodiment. Figure 1 As shown, this embodiment provides a water softening device, which includes a tank body 200, a bottom cover 300, and a water distributor assembly 100. The top of the tank body 200 is provided with a first water inlet 202 and a second water inlet 203, and the bottom of the tank body 200 is provided with a mounting opening. The bottom cover 300 is detachably mounted on the mounting opening, and a receiving space 201 is formed between the tank body 200 and the bottom cover 300. The water distributor assembly 100 is disposed in the receiving space 201, and the space between the water distributor assembly 100 and the receiving space 201 is filled with resin. During use, the first water inlet 202 is connected to an external water source, and the second water inlet 203 is connected to an external water outlet. Water from the external water source enters the receiving space 201 through the first water inlet 202, is evenly distributed by the water distributor assembly 100, and is softened by the resin before flowing out of the second water inlet 203 to the external water outlet for user use.

[0043] Optionally, external threads are provided on the outer walls of the first water outlet 202 and the outer walls of the second water outlet 203 to connect them with corresponding external water channels. The threaded connection has the advantages of easy assembly and disassembly and a stable connection.

[0044] In this embodiment, the bottom cover 300 is threadedly connected to the mounting opening, providing easy assembly and disassembly, a secure connection, and convenient resin filling and replacement. To ensure a tight seal between the bottom cover 300 and the can body 200, a first sealing member 401 is provided between the bottom cover 300 and the mounting opening. This first sealing member 401 is a rubber sealing ring, which provides a good sealing effect and is low in cost.

[0045] Figure 2 FIG. 2 shows a schematic diagram of the explosion structure of the hidden tank 200 of the water softening device provided in this embodiment. Figure 2 Combined with Figure 1As shown, the water distributor assembly 100 includes a central tube 110, an upper water distributor 120, and a lower water distributor 130. The upper water distributor 120 is connected to the top of the central tube 110. The lower water distributor 130 includes a lower water distributor body 131 and a plug-in protrusion 132 protruding from the lower water distributor body 131. The plug-in protrusion 132 is plugged into the central tube 110 from the bottom. By providing the plug-in protrusion 132 on the lower water distributor body 131, when the water softening device is assembled, after the tank 200 is filled with resin, the plug-in protrusion 132 of the lower water distributor 130 can be aligned with the bottom of the central tube 110 and inserted into the central tube 110. This prevents the lower water distributor 130 from squeezing the resin during assembly with the central tube 110, thereby ensuring the performance of the resin and the softening effect of the water softening device, and improving the user experience.

[0046] In this embodiment, a through hole 1321 is provided in the plug-in protrusion 132, and the through hole 1321 is connected to the bottom of the central tube 110. Specifically, an upper water distribution space is formed between the upper water distributor 120 and the inner top wall of the tank body 200, a lower water distribution space is formed between the lower water distributor 130 and the bottom cover 300, and a filling space for filling resin is formed between the upper water distributor 120 and the lower water distributor 130. The upper water distributor 120 is provided with an upper water distribution hole 12401 connecting the upper water distribution space and the filling space, and the lower water distributor 130 is provided with a lower water distribution hole 1301 connecting the lower water distribution space and the filling space. The two ends of the through hole 1321 are respectively connected to the central tube 110 and the lower water distribution space, and the top of the central tube 110 is connected to the second water outlet 203. During use, water from the external water source flows through the first water outlet 202, the upper water distribution space, and the upper water distribution hole 12401 in sequence, and then flows into the filling space to be softened by the resin. The softened water then flows through the lower water distribution hole 1301, the lower water distribution space, the through hole 1321, and the central tube 110, and then flows out from the second water outlet 203 for user use.

[0047] Optionally, an upper limit member 126 is provided on the upper water distributor 120, and an upper skeleton structure (not shown in the figure) that abuts the upper limit member 126 is provided on the inner top wall of the tank body 200. By providing the abutting upper limit member 126 and the upper skeleton structure, on the one hand, it can serve as a reminder that the upper water distributor 120 is in place. When the upper water distributor 120 is installed in the tank body 200, when the upper limit member 126 abuts against the inner top wall of the tank body 200, it indicates that both are installed in place; on the other hand, it can also serve as a limit for the upper water distributor 120, to prevent the resin from squeezing the upper water distributor 120 when filling the tank body 200 with resin, so that the top of the upper water distributor 120 is against the inner top wall of the tank body 200, resulting in too small an upper water distribution space that affects the uniformity of water distribution. Optionally, there are multiple upper limit positioning members 126, and the multiple upper limit positioning members 126 are arranged at intervals along the circumference of the upper water distributor 120. The upper skeleton structure includes multiple upper limit positioning bones corresponding to the upper limit positioning members 126 one by one, and the multiple upper limit positioning members 126 and the multiple upper limit positioning bones are supported one by one.

[0048] like Figure 1-Figure 2 As shown, a mounting groove 301 is provided on the bottom cover 300, and the lower water distributor 130 is sealed and installed in the mounting groove 301, and the above-mentioned lower water distribution space is formed between the lower water distributor 130 and the bottom of the mounting groove 301. This arrangement can, on the one hand, improve the limiting effect of the lower water distributor 130, so that the water distribution process of the water distributor assembly 100 is more stable. In addition, it can also play a role in positioning the lower water distributor 130 and the bottom cover 300 to a certain extent when assembling, so as to achieve fast and accurate installation between the lower water distributor 130 and the bottom cover 300. On the other hand, since the lower water distributor 130 is accommodated in the mounting groove 301 of the bottom cover 300, it can ensure that there is enough space between the upper water distributor 120 and the lower water distributor 130 to accommodate the resin, further avoiding the situation of squeezing the resin when assembling the lower water distributor 130, thereby ensuring the performance of the resin and the softening effect of the water softening equipment.

[0049] To ensure the sealing of the lower water distribution space, a second sealing member 402 is provided between the outer wall of the lower water distributor 130 and the wall of the mounting groove 301 to prevent water in the lower water distribution space from flowing back into the filling space. In this embodiment, the second sealing member 402 is a rubber sealing ring, which has a good sealing effect and is low in cost.

[0050] Optionally, a lower limit member (not shown in the figure) is provided on the lower water distributor 130, and a lower skeleton structure 302 that abuts against the lower limit member is provided in the bottom cover 300. By providing the abutting lower limit member and the lower skeleton structure 302, on the one hand, it can serve as a reminder that the installation is in place. When assembling the lower water distributor 130 and the bottom cover 300, when the lower limit member abuts against the lower skeleton structure 302, it indicates that both have been installed in place; on the other hand, it can also serve as a limit for the lower water distributor 130, preventing the lower water distributor 130 from being too close to the bottom of the installation groove 301, resulting in too small a lower water distribution space and affecting the uniformity of water distribution. Optionally, there are multiple lower limit members, and the multiple lower limit members are arranged at intervals along the circumference of the lower water distributor 130. The lower skeleton structure 302 includes multiple lower limit bones corresponding to the lower limit members, and the multiple lower limit members and the multiple lower limit bones abut against each other.

[0051] Figure 3 FIG. 1 shows a schematic structural diagram of the central tube 110 provided in this embodiment. Figure 3 and combined Figure 1 、 Figure 2 As shown, a limiting groove 1311 is provided on the lower water distributor body 131 and is arranged around the plug-in protrusion 132. The bottom of the central pipe 110 is inserted into the limiting groove 1311, which can realize the dual limiting effect of the assembly of the central pipe 110 and the lower water distributor 130, and further ensure the stability of the assembly between the two.

[0052] Optionally, a first limiting step 111 is provided on the inner wall of the central tube 110, and the top of the plug-in protrusion 132 abuts against the first limiting step 111. The provision of the first limiting step 111, on the one hand, can serve as a reminder of the installation in place. When the central tube 110 and the lower water distributor 130 are assembled, when the plug-in protrusion 132 abuts against the first limiting step 111, it indicates that both are installed in place. On the other hand, it can also serve as a limit for the lower water distributor 130, preventing the lower water distributor 130 from squeezing the resin due to the plug-in protrusion 132 being inserted too deeply into the central tube 110 when the lower water distributor 130 is installed in the tank body 200, thereby affecting the performance of the resin.

[0053] To facilitate assembly between the plug-in protrusion 132 and the center tube 110, in this embodiment, the bottom opening of the center tube 110 is flared. Of course, in other embodiments, a guide slope can be provided on the top of the plug-in protrusion 132, gradually sloping upward toward the center of the lower water distributor body 131. Both of these arrangements enable quick assembly of the plug-in protrusion 132 and the center tube 110.

[0054] Continue as Figure 1-Figure 3As shown, the upper water distributor 120 is provided with an upper plug hole 1201, and the top of the central tube 110 is plugged into the upper plug hole 1201 to achieve plug-in cooperation between the upper water distributor 120 and the central tube 110. Optionally, a second limiting step 112 is provided on the central tube 110, and a supporting protrusion 1202 is protruded downward from the bottom surface of the upper water distributor 120. The supporting protrusion 1202 is a hollow annular structure and is arranged around the upper plug hole 1201. The top of the central tube 110 is plugged into the supporting protrusion 1202, and the supporting protrusion 1202 is supported by the second limiting step 112 to play a limiting role during assembly between the upper water distributor 120 and the central tube 110. In this embodiment, the second limiting step 112 is an annular protrusion provided on the tube wall of the central tube 110.

[0055] like Figure 1 As shown, the second water outlet 203 is a stepped hole, and the large end of the second water outlet 203 is arranged toward the interior of the tank body 200. After the top of the central tube 110 is inserted into the upper plug hole 1201, it can be partially inserted into the second water outlet 203 to further ensure the stable assembly between the water distributor assembly 100 and the tank body 200. In addition, the above-mentioned arrangement can also make the top of the central tube 110 higher than the filling height of the resin to ensure that the resin will not fall into the central tube 110 when filling. Optionally, a fourth sealing member 404 is provided between the central tube 110 and the second water outlet 203 to ensure the sealed assembly between the central tube 110 and the second water outlet 203, and to prevent the water in the upper water distribution space from flowing directly out of the second water outlet 203 through the gap between the central tube 110 and the second water outlet 203, thereby affecting the soft water effect.

[0056] Optionally, a third seal 403 is provided between the upper water distributor 120 and the tank body 200 to ensure the sealing between the two and prevent the water flowing into the upper water distribution space from the first water outlet 202 from flowing directly from the gap between the upper water distributor 120 and the tank body 200 into the filling space, affecting the uniformity of water distribution.

[0057] The following combination Figure 1 and Figure 4 Briefly describe the assembly process of the water softener:

[0058] 1) Install the third sealing member 403 on the outer wall of the upper water distributor 120 and the fourth sealing member 404 on the top of the central tube 110. Then, insert the top of the central tube 110 into the upper insertion hole 1201, and make the abutting protrusion 1202 abut against the second limiting step 112.

[0059] 2) Insert the assembled upper water distributor 120 and center tube 110 into the tank body 200 together, and insert the top of the center tube 110 into the second water outlet 203. At this time, the fourth sealing member 404 provided on the outer surface of the center tube 110 is tightly pressed against the inner wall of the second water outlet 203, the third sealing member 403 provided on the outer surface of the upper water distributor 120 is tightly pressed against the inner wall of the tank body 200, and the upper limit member 126 is pressed against the upper frame structure.

[0060] 3) Fill the tank 200 with resin from the installation port at the bottom of the tank 200;

[0061] 4) Install the second sealing member 402 on the outer wall of the lower water distributor 130 and the first sealing member 401 on the outer wall of the bottom cover 300. Then install the lower water distributor 130 in the installation groove 301 of the bottom cover 300, and use the second sealing member 402 to achieve a sealed assembly of the lower water distributor 130 and the bottom cover 300. At this time, the lower limit member and the lower frame structure 302 are in contact with each other.

[0062] 5) Install the assembled lower water distributor 130 and bottom cover 300 together on the tank body 200, align the plug-in protrusion 132 with the bottom of the central tube 110 and insert it, then screw the bottom cover 300 into the installation port at the bottom of the tank body 200, and install it in place when the first limiting step 111 abuts against the top of the plug-in protrusion 132. At this time, the first sealing member 401 arranged on the outer surface of the bottom cover 300 presses against the inner wall of the tank body 200 to ensure a sealed assembly between the two.

[0063] Figure 4 The schematic diagram of the water path of the water softening device provided in this embodiment during the water softening operation is shown below. Figure 1-Figure 4 Briefly describe the working principle of the water softener:

[0064] 1) During normal operation: Water from the external water source flows through the first water outlet 202, the upper water distribution space, and the upper water distribution hole 12401 in sequence, then flows into the filling space and is softened by the resin. The softened water then flows through the lower water distribution hole 1301, the lower water distribution space, the through hole 1321, and the central tube 110, and then flows out of the second water outlet 203 for user use.

[0065] 2) During the regeneration process: the brine flows into the filling space through the second water outlet 203, the central tube 110, the through hole 1321, the lower water distribution space and the lower water distribution hole 1301 in sequence, regenerating the resin to form waste water, which then flows through the upper water distribution hole 12401 and the upper water distribution space in sequence and is discharged from the first water outlet 202.

[0066] It should be noted that the sizes of the upper water distribution hole 12401 and the lower water distribution hole 1301 can allow water to pass through but not allow resin to pass through.
