[0054] Figure 1 FIG. 2 shows a schematic cross-sectional view of a water softening device provided by the present invention. Figure 1As shown, the present invention 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 outlet 202 and a second water outlet 203, and the bottom of the tank body 200 is provided with a mounting port; the bottom cover 300 is detachably arranged at the mounting port, and a receiving space 201 is formed between the tank body 200 and the bottom cover 300; the water distributor assembly 100 is arranged in the receiving space 201, and resin is filled between the water distributor assembly 100 and the receiving space 201. When in use, the first water outlet 202 is connected to an external water source, and the second water outlet 203 is connected to an external water outlet. Water in the external water source enters the receiving space 201 through the first water outlet 202, and after the water distributor assembly 100 evenly distributes water, it is softened by the resin, and finally flows out from the second water outlet 203 to the external water outlet for users to take.

[0055] Optionally, the bottom cover 300 is threadedly connected to the mounting port, which is convenient for assembly and disassembly, and the connection is stable. To ensure the sealing between the bottom cover 300 and the tank body 200, a first sealing member 401 is provided between the bottom cover 300 and the mounting port. The first sealing member 401 is a rubber sealing ring, which has a good sealing effect and low cost.

[0056] Optionally, external threads are provided on the outer walls of the first water outlet 202 and 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.

[0057] However, the water distributor assembly 100 in the prior art often has the problem of uneven water distribution, resulting in low utilization of the resin and failure to fully exert the performance of the resin. In order to solve this problem, the present invention also provides a water distributor assembly 100 capable of achieving uniform water distribution. The specific structure of the water distributor assembly 100 is introduced through multiple embodiments below.

[0058] Embodiment 1

[0059] Figure 2 FIG. 1 shows a schematic diagram of the structure of the upper water distributor 120 provided in this embodiment. Figure 2 Combined with Figure 1As shown, the water distributor assembly 100 provided in this embodiment 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 is connected to the bottom of the central tube 110, and the central tube 110 is connected to the second water outlet 203. 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, an upper water distribution hole 12401 connecting the upper water distribution space and the filling space is provided on the upper water distributor 120, and a lower water distribution hole 1301 connecting the lower water distribution space and the filling space is provided on the lower water distributor 130 (refer to Figure 4 ). The water in the external water source flows into the filling space through the first water outlet 202, the upper water distribution space, and the upper water distribution hole 12401 in sequence, and is softened by the resin. The softened water then flows out from the second water outlet 203 through the lower water distribution hole 1301, the lower water distribution space, and the central tube 110 for users to take.

[0060] To achieve uniform water distribution, the upper water distributor 120 includes an inner ring 121, an outer ring 122 and a guide member 123. The outer ring 122 is arranged outside the inner ring 121 to form an annular water outlet area between the inner ring 121 and the outer ring 122. The guide member 123 is arranged between the inner ring 121 and the outer ring 122, and the end of the guide member 123 close to the outer ring 122 is directly opposite to the first water outlet 202 on the tank body 200. The guide member 123 can guide the water thereon to flow from the outer ring 122 to the inner ring 121, so that the water flows from the inner ring 121 to the water outlet area. With the above arrangement, water flowing into the upper water distribution space from the first water outlet 202 first passes through the guide member 123, and can flow to the inner ring 121 under the guiding action of the guide member 123. The water at the inner ring 121 flows along its circumference to the water outlet area under continuous water inlet pressure, thereby achieving uniform water distribution, improving the utilization rate of the resin, giving full play to the performance of the resin, improving the softening effect, and enhancing the user experience.

[0061] In this embodiment, the top surface of the guide member 123 is the first guide surface, and the first guide surface gradually tilts downward from the outside to the inside along the radial direction of the outer ring 122 to ensure that the water flowing onto the guide member 123 can quickly flow to the inner ring 121 along the inclined first guide surface. Optionally, water retaining members 125 are provided on both sides of the guide member 123, and the water retaining members 125 can play a role in blocking the water flow to prevent the water flowing onto the first guide surface from directly flowing from both sides of the guide member 123 to the water outlet area, affecting the uniform water distribution of the upper water distributor 120.

[0062] The upper water distributor 120 also includes a orifice plate 124, which is connected between the inner ring 121 and the outer ring 122. A plurality of upper water distribution holes 12401 are provided on the orifice plate 124 to form a water outlet area. Along the radial direction of the orifice plate 124, the orifice plate 124 gradually tilts downward from the inside to the outside to provide guidance for the water flowing to the inner ring 121 so that it can quickly flow to each upper water distribution hole 12401.

[0063] Specifically, the orifice plate 124 includes annular ribs 1241 and radial transverse ribs 1242. A plurality of annular ribs 1241 are arranged between the inner ring 121 and the outer ring 122 at intervals along the radial direction of the outer ring 122; a plurality of radial transverse ribs 1242 are arranged at intervals along the circumference of the inner ring 121, and the two ends of each radial transverse rib 1242 are respectively connected to the inner ring 121 and the outer ring 122. A plurality of annular ribs 1241 and a plurality of radial transverse ribs 1242 are staggered to form the above-mentioned upper water distribution holes 12401. Optionally, the top surface height of the radial transverse ribs 1242 gradually tilts downward from the inside to the outside along the radial direction of the outer ring 122 to form a second guide surface for guiding the water at the inner ring 121. The water at the inner ring 121 can flow to the upper water distribution holes 12401 located on both sides of the radial transverse ribs 1242 in sequence under the guiding effect of the second guide surface, further ensuring the uniformity of the water distribution of the upper water distributor 120.

[0064] Optionally, the width of the upper water distribution hole 12401 gradually decreases from top to bottom. This design can provide guidance for the water in the water outlet area on the one hand, and can also prevent the resin from entering the upper water distribution space through the upper water distribution hole 12401 on the other hand.

[0065] like Figure 2 As shown, in one embodiment, the two ends of the guide member 123 are respectively connected to the inner ring 121 and the outer ring 122, so as to facilitate processing and ensure the structural strength of the upper water distributor 120. In another embodiment, one end of the guide member 123 is connected to the inner ring 121, and the other end extends in the direction close to the outer ring 122 and faces the first water outlet 202; or one end of the guide member 123 is connected to the outer ring 122 and faces the first water outlet 202, and the other end of the guide member 123 extends in the direction close to the inner ring 121. This design can also achieve the above effect. In another embodiment, the guide member 123 can be arranged on the orifice plate 124, and the two ends of the guide member 123 are not connected to the inner ring 121 or the outer ring 122. In other words, this embodiment does not limit the arrangement of the guide member 123, as long as it can ensure that one end thereof faces the first water outlet 202, so as to guide the water flowing into the upper water distribution space from the first water outlet 202 to the inner ring 121.

[0066] Figure 3 FIG. 2 shows a schematic diagram of the structure of the tank body 200 provided in this embodiment. Figure 3 Combined with Figure 1 , Figure 2 As shown, an upper limit member 126 is provided on the orifice plate 124, and the upper limit member 126 can abut against the inner top wall of the tank body 200 to form the upper water distribution space mentioned above between the upper water distributor 120 and the tank body 200. By providing the upper limit member 126, on the one hand, it can play a role of reminding that the upper water distributor 120 is installed in place. When the upper water distributor 120 is installed in the tank body 100, 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 play a role of limiting the upper water distributor 120, so as to avoid the resin squeezing the upper water distributor 120 when filling the resin into the tank body 200, so that the top of the upper water distributor 120 is against the inner top wall of the tank body 200, resulting in the upper water distribution space being too small to affect the uniformity of water distribution. In this embodiment, the upper limit positioning member 126 is disposed on the radial transverse ribs 1242 , and the radial transverse ribs 1242 provide an installation position for the upper limit positioning member 126 , thereby ensuring a stable connection between the upper limit positioning member 126 and the orifice plate 124 .

[0067] In this embodiment, the inner top wall of the tank body 200 is provided with an upper frame structure 204 corresponding to the upper limit stopper 126, and the upper limit stopper 126 abuts against the upper frame structure 204. Optionally, there are multiple upper limit stoppers 126, and the multiple upper limit stoppers 126 are arranged at intervals along the circumference of the inner ring 121, and the upper frame structure 204 includes multiple upper limit bones corresponding to the upper limit stoppers 126 one by one, and the multiple upper limit stoppers 126 and the multiple upper limit bones abut against each other one by one.

[0068] In order to ensure the assembly accuracy between the upper water distributor 120 and the tank body 200, a positioning hole 205 is provided on the inner top wall of the tank body 200, and an upper positioning member 127 that is plugged and matched with the positioning hole 205 is provided on the upper water distributor 120. The upper positioning member 127 cooperates with the positioning hole 205 to realize the rapid positioning and accurate installation of the upper water distributor 120 and the tank body 200. In this embodiment, the number of positioning holes 205 is two, and each positioning hole 205 corresponds to an upper positioning member 127 to avoid the upper water distributor 120 rotating around the axis of the positioning hole 205 when the upper water distributor 120 and the tank body 200 are assembled, thereby affecting the assembly efficiency. Of course, this embodiment does not limit the number of positioning holes 205, and it can also be three, four, five, or even more. Designers can adjust according to actual needs. It is understandable that, in other embodiments, the upper positioning member 127 may be disposed on the inner top wall of the tank body 200 , and the positioning hole 205 may be disposed on the upper water distributor 120 , which can also achieve the above-mentioned effects.

[0069] Alternatively, if Figure 1As shown, 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 to the filling space, affecting the uniformity of water distribution.

[0070] In order to further improve the structural stability of the upper water distributor 120, the upper water distributor 120 is an integrated structure, which omits the assembly process between multiple parts and components, and has a higher processing efficiency.

[0071] Figure 4 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 4 Combined with Figure 1 As shown, the upper water distributor 120 is plugged into the top of the central tube 110; the lower water distributor 130 is plugged into the bottom of the central tube 110, and the connection is stable and easy to assemble.

[0072] Specifically, an upper plug hole 1201 is provided on the upper water distributor 120, and the top of the center tube 110 is plugged into the upper plug hole 1201 to achieve the plug-in fit between the upper water distributor 120 and the center tube 110. In the present embodiment, the upper plug hole 1201 is opened on the inner ring 121. Optionally, a second limiting step 112 is provided on the center tube 110, and a supporting protrusion 1202 is protruding downward on 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 center 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 in the assembly between the upper water distributor 120 and the center tube 110. In this embodiment, the second limiting step 112 is an annular protrusion disposed on the tube wall of the central tube 110 .

[0073] 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 inside 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 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.

[0074] Continue as Figure 1 and Figure 4 As shown, the lower water distributor 130 is provided with a lower plug hole 1302, and the bottom of the central tube 110 is plugged into the lower plug hole 1302 to achieve the plug-in fit between the lower water distributor 130 and the central tube 110. Optionally, a third limiting step 113 is provided on the tube wall of the central tube 110, and the lower water distributor 130 can abut against the third limiting step 113. The setting of the third limiting step 113 can, on the one hand, serve as a reminder of installation in place. When the central tube 110 and the lower water distributor 130 are assembled, the lower water distributor 130 abuts against the third limiting step 113, indicating that both are installed in place; on the other hand, it can also serve as a limiting role for the lower water distributor 130, so as to avoid the lower water distributor 130 from squeezing the resin due to the central tube 110 being inserted too deeply into the lower plug hole 1302 when the lower water distributor 130 is installed in the tank body 200, thereby affecting the performance of the resin. In this embodiment, the third limiting step 113 is an annular protrusion disposed on the tube wall of the central tube 110 .

[0075] Figure 5 A schematic structural diagram of the lower water distributor 130 provided in this embodiment is shown. Figure 6 FIG. 3 shows a schematic structural diagram of the bottom cover 300 provided in this embodiment. Figure 7 FIG. 2 shows a schematic cross-sectional view of the water softening device provided in this embodiment. Figure 5-Figure 7 Combined with Figure 1 As shown, a mounting groove 301 is provided on the bottom cover 300, and the lower water distributor 130 is installed in the mounting groove 301, and the above-mentioned lower water distribution space is formed between the two. With this arrangement, on the one hand, the limiting effect of the lower water distributor 130 can be improved, 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 when they are assembled to a certain extent, 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 be ensured 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 use performance of the resin and the softening effect of the water softening equipment.

[0076] 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 groove wall of the mounting groove 301 to prevent the 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 low cost.

[0077] Optionally, a plurality of water passages are formed between the lower water distributor 130 and the bottom cover 300 and are radially distributed along the circumference of the bottom cover 300 to achieve uniform diffusion of water in the lower water distribution space. When the water above the lower water distributor 130 flows to the lower water distribution space, the water flow can flow along the plurality of water passages to the center of the lower water distributor 130, and then flow into the interior of the central tube 110 from the bottom of the central tube 110. Specifically, a lower skeleton structure 302 is provided on the bottom cover 300, and the lower skeleton structure 302 includes a plurality of lower limit bones arranged at intervals along the circumference of the bottom cover 300, and a positioning groove 303 is formed between two adjacent lower limit bones; a lower limit piece 1304 corresponding to the lower limit bones one by one and a lower positioning piece 1303 corresponding to the positioning groove 303 are provided at the bottom of the lower water distributor 130, and the lower limit bone and the lower limit piece 1304 and the positioning groove 303 and the lower positioning piece 1303 cooperate to form the above-mentioned water passage.

[0078] By setting the lower limit bone and the lower limit member 1304 that can correspond to each other and abut against each other, on the one hand, it can play the role of reminding that the installation is in place. When assembling the lower water distributor 130 and the bottom cover 300, when the lower limit member 1304 abuts against the lower frame structure 302, it means that both have been installed in place; on the other hand, it can also play the role of limiting the lower water distributor 130, so as to avoid the lower water distributor 130 and the bottom of the installation groove 301 being too close to each other, resulting in too small lower water distribution space and affecting the uniformity of water distribution. By setting the positioning groove 303 and the lower positioning member 1303 that can cooperate with each other, the lower water distributor 130 and the bottom cover 300 can be quickly positioned and accurately installed; in addition, the lower positioning member 1303 inserted in the positioning groove 303 can also play the role of guiding the water flow at the center of the central tube 110 or in the water passage, so as to further ensure the uniform diffusion of water in the lower water distribution space. The water passage formed by the cooperation of the lower limit bone, the lower limit member 1304, the positioning groove 303 and the lower positioning member 1303 can make the water in the lower water distribution space evenly distributed in the entire lower water distribution space, thereby achieving uniform diffusion of water, avoiding excessive water flow or water overflow at a certain position in the lower water distribution space, and further ensuring full utilization or uniform regeneration of the resin.

[0079] This embodiment does not limit the specific number of the lower limit members 1304, and designers can adjust it according to actual needs.

[0080] Combine the following Figure 1 and Figure 4 Briefly describe the assembly process of the water softener:

[0081] 1) A third sealing member 403 is sleeved on the outer wall of the upper water distributor 120, and a fourth sealing member 404 is sleeved on the top of the central tube 110, and then the top of the central tube 110 is inserted into the upper plug hole 1201, and the abutting protrusion 1202 is abutted against the second limiting step 112;

[0082] 2) Insert the assembled upper water distributor 120 and the central tube 110 into the tank body 200 together, and use the upper positioning member 127 and the positioning hole 205 to accurately position them. At the same time, the top of the central tube 110 is inserted into the second water outlet 203. At this time, the fourth sealing member 404 disposed on the outer surface of the central tube 110 is pressed against the inner wall of the second water outlet 203, the third sealing member 403 disposed on the outer surface of the upper water distributor 120 is pressed against the inner wall of the tank body 200, and the upper limit member 126 is pressed against the upper skeleton structure 204;

[0083] 3) Filling the resin into the tank body 200 from the installation opening at the bottom of the tank body 200;

[0084] 4) A second sealing member 402 is sleeved on the outer wall of the lower water distributor 130, and a first sealing member 401 is sleeved on the outer wall of the bottom cover 300, and then the lower water distributor 130 is installed in the installation groove 301 of the bottom cover 300, and the second sealing member 402 is used to realize the sealing assembly of the lower water distributor 130 and the bottom cover 300, at which time, the lower limit member 1304 and the lower frame structure 302 are abutted against each other;

[0085] 5) Install the assembled lower water distributor 130 and bottom cover 300 together on the tank body 200, insert the bottom of the central tube 110 into the lower plug hole 1302, and screw the bottom cover 300 into the installation port at the bottom of the tank body 200. When the third limiting step 113 abuts against the lower water distributor 130, it is installed in place. At this time, the first sealing member 401 arranged on the outer surface of the bottom cover 300 abuts against the inner wall of the tank body 200 to ensure the sealing assembly between the two.

[0086] Figure 8 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 8 Briefly describe the working principle of the water softener:

[0087] 1) During normal operation: water from the external water source flows into the upper water distribution space through the first water outlet 202 in sequence, and flows to the inner ring 121 under the guiding action of the guide member 123. The water at the inner ring 121 flows to the upper water distribution holes 12401 along its circumferential direction under the continuous water inlet pressure, and then enters the filling space to be softened by the resin. The softened water then flows out from the second water outlet 203 through the lower water distribution holes 1301, the lower water distribution space, and the central tube 110 for users to take;

[0088] 2) During the regeneration process: the brine flows into the filling space through the second water outlet 203, the central tube 110, the lower water distribution space and the lower water distribution hole 1301 in turn, and forms waste water after the resin is regenerated. The waste water then flows through the upper water distribution hole 12401 and the upper water distribution space in turn and is discharged from the first water outlet 202.

[0089] 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.

[0090] Embodiment 2

[0091] This embodiment provides a water distributor assembly 100, the specific structure of which is substantially the same as that of the water distributor assembly 100 in the first embodiment, except that the assembly method of the lower water distributor 130 and the central pipe 110 is different.

[0092] Fig. 9 A cross-sectional schematic diagram of the water softening device provided in this embodiment is shown. Fig.10 FIG. 1 shows a schematic diagram of the structure of the central pipe 110 and the lower water distributor 130 provided in this embodiment. Figure 9-10 As shown, in this embodiment, 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, and the plug-in protrusion 132 is plugged into the bottom of the central tube 110. 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 to avoid the situation where the resin is squeezed when the lower water distributor 130 and the central tube 110 are assembled, thereby ensuring the use performance of the resin and the softening effect of the water softening device, and improving the user experience.

[0093] 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. When in use, water from the external water source flows into the filling space through the first water outlet 202, the upper water distribution space, and the upper water distribution hole 12401 in sequence, and is softened by the resin. The softened water then flows out from the second water outlet 203 through the lower water distribution hole 1301, the lower water distribution space, the through hole 1321, and the central tube 110 for users to take.

[0094] Optionally, 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 center pipe 110 is inserted into the limiting groove 1311, which can realize the dual limiting effect of the assembly of the center pipe 110 and the lower water distributor 130, and further ensure the stability of the assembly between the two.

[0095] 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 can, on the one hand, serve as a reminder of 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 have been installed in place; on the other hand, it can also serve as a limiting role for the lower water distributor 130, so as to avoid the lower water distributor 130 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.

[0096] In order to facilitate the assembly between the plug-in protrusion 132 and the central tube 110, in this embodiment, the bottom pipe opening of the central tube 110 is flared. Of course, in other embodiments, a guide slope can also be provided on the top of the plug-in protrusion 132, and the guide slope gradually tilts from bottom to top toward the center of the lower water distributor body 131. Both of the above-mentioned settings can achieve rapid assembly of the plug-in protrusion 132 and the central tube 110.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
