[0052] The technical scheme of the present application is further illustrated below by combining the drawings and through specific embodiments.

[0053] Referring to Figures 1 to 3 The present embodiment provides a water distributor 10, the water distributor 10 has a water-facing surface 11, the water-facing surface 11 has a water inlet level 12 capable of being directly opposite to a water inlet flow, a water guide channel 13 is provided on the water distributor 10 in a direction penetrating the water-facing surface 11, and the flow area of the water guide channel 13 gradually increases in a direction away from the water inlet level 12.

[0054] The water inlet flow impacts the water inlet level 12, the water flow at the water inlet level 12 is the largest, and the water flow flows out of the water distributor 10 along the water guide channel 13 on the water-facing surface 11, and since the flow area of the water guide channel 13 gradually increases in the direction away from the water inlet level 12, the water flow can flow out of the water distributor 10 faster at the position away from the water inlet level 12, so that the water flow is more evenly distributed.

[0055] The water-facing surface 11 of the water distributor 10 is the surface of the water distributor 10 facing the water flow. For example, the water flow flows from top to bottom to the water distributor 10, and the top surface of the water distributor 10 is the water-facing surface 11. The water flows into the water inlet level 12 and flows into the water guide channel 13 along the water-facing surface 11. The water flows out of the water guide channel 13 and then out of the water distributor 10.

[0056] The shape of the water distributor 10 is determined according to the use space where the water distributor 10 is located, such as rectangular or circular. In this embodiment, the water distributor 10 is in the shape of a circular ring.

[0057] The water guide channel 13 is provided with a plurality of water guide channels 13, each of which extends in the shape of a ring around the circumference of the water distributor 10. Each water guide channel 13 includes a plurality of water guide holes 131 arranged at intervals. The water guide channel 13 is arranged to make full use of the space of the water distributor 10 to ensure sufficient flow area so that the water flow can quickly pass through the water distributor 10. For example, the water guide channel 13 is provided with three water guide channels 13, which are distributed in three concentric circular rings around the circumference of the water distributor 10.

[0058] The shape of the water guide hole 131 can be set according to actual needs, such as circular, oval, strip-shaped or rectangular. Since the water flow flows from the water inlet level 12 and flows away from the water inlet level 12, the direction away from the water inlet level 12 is the direction of the water flow.

[0059] In this embodiment, the water guide hole 131 extends in the shape of a circular arc around the circumference of the water distributor 10, so that the water guide hole 131 is arranged in the direction of the water flow. In the direction away from the water inlet level 12, the flow area of a single water guide hole 131 gradually increases. On the same circular ring, the minimum end of the downstream water guide hole 131 is greater than the maximum end of the upstream water guide hole 131 between adjacent water guide holes 131, so that the flow area of each water guide channel 13 gradually increases in the direction away from the water inlet level 12.

[0060] In other embodiments, in the direction away from the water inlet level 12, the flow area of the downstream water guide hole 131 is greater than the flow area of the upstream water guide hole 131 between adjacent water guide holes 131. For example, the water guide hole 131 is circular, and the plurality of water guide holes 131 on each water guide channel 13 are arranged at intervals around the circumference of the water distributor 10. In the direction away from the water inlet level 12, the diameter of the water guide hole 131 gradually increases.

[0061] For a plurality of water guide channels 13, in the radial direction of the water distributor 10, the flow area at the same radial position in the adjacent two water guide channels 131 can be the same or different.

[0062] The water distributor 10 is provided with a shielding part at the water inlet level 12, the shielding part is a non-porous structure, and the water guide channels 13 are distributed around the shielding part. By setting the shielding part as a non-porous structure, the water flow at the water inlet level 12 will not directly flow out of the water distributor 10, but will flow along the water-facing surface 11 and out of the water distributor 10 through the water guide channels 13. Since the water flow at the water inlet level 12 is the largest, the shielding part is set as a non-porous structure to avoid water flow from the water inlet level 12, thereby ensuring uniform distribution of water flow.

[0063] In some embodiments, the water-facing surface 11 is a plane, and the shielding part is a planar shielding part. In some embodiments, the water-facing surface 11 is a plane, and the shielding part protrudes from the water-facing surface 11. Illustratively, the shielding part has a water guide surface that gradually decreases from the middle to the periphery to guide the water flow to the water guide channels 13. By setting the water guide surface, it is more conducive for the water at the water inlet level 12 to flow to the periphery.

[0064] The outer peripheral edge of the water distributor 10 is folded downward to form a first folded edge 14, so that the lower side of the water distributor 10 forms a first accommodating cavity to provide space for water flow. The outer peripheral edge of the water distributor 10 is provided with a plurality of positioning grooves 15 to facilitate positioning when the water distributor 10 is installed.

[0065] Referring to Figures 4 to 19 , the embodiment also provides a water distribution device, which comprises the above-mentioned water distributor 10 and further comprises a central pipe 20, the water distributor 10 is sleeved on the upper part of the central pipe 20, and the water-facing surface 11 is arranged in an annular shape around the central pipe 20. In use, the water inlet flow flows to the water inlet level 12 of the water distributor 10, and the central pipe 20 is used for water outlet.

[0066] The water distributor 10 is coaxially arranged with the central pipe 20. The water distributor 10 comprises a central hole 16 for penetrating the central pipe 20. The water inlet level 12 of the water distributor 10 is arranged eccentrically relative to the water distributor 10, i.e. on one side of the central pipe 20, and the water inlet flow flows to both sides from the water inlet level 12 along the annular water-facing surface 11.

[0067] The water distribution device further comprises a first water distributor 30, the first water distributor 30 is sleeved on the central pipe 20 and arranged on the lower side of the water distributor 10, and a plurality of first water distribution holes 31 are formed in the first water distributor 30. The water flowing out of the water distributor 10 flows out of the first water distributor 30 through the first water distribution holes 31 of the first water distributor 30.

[0068] The first water distributor 30 is coaxially arranged with the central pipe 20. The first water distributor 30 comprises a first central hole 35 for penetrating the central pipe 20. The first water distribution holes 31 extend in a circular arc around the circumference of the first water distributor 30. The plurality of first water distribution holes 31 are distributed on a plurality of concentric circles.

[0069] The lower side of the first water distributor 30 is used to set the resin layer, and the upper side of the first water distributor 30 is provided with the water distributor 10, and the water flows from top to bottom, first passes through the water distributor 10, and then flows into the resin layer through the first water distributor 30. The first water holes 31 penetrate the first water distributor 10 along the axial direction of the first water distributor 30, so as to facilitate the water flow out of the first water distributor 30.

[0070] The aperture of the end of the first water hole 31 close to the resin layer is smaller than the particle size of the resin particles, so as to prevent the resin from entering the upper side of the first water distributor 30.

[0071] Along the axial direction of the first water distributor 30, the flow area of the first water hole 31 can be uniform, or the flow area of the first water hole 31 gradually decreases along the axial direction of the first water distributor 30, and the end of the first water hole 31 close to the resin layer is the smallest end of the first water hole 31.

[0072] In the embodiment, the surface of the first water distributor 30 close to the water distributor 10 is provided with a plurality of first water guide protrusions 32, the first water guide protrusions 32 extend along the radial direction of the first water distributor 30, and the first water holes 31 are arranged between adjacent first water guide protrusions 32. By arranging the first water guide protrusions 32, the circumferential flow of the water flow is reduced, so that the water flow is more uniform.

[0073] When the first water distributor 30 is placed on the lower side of the water distributor 10, the first water guide protrusions 32 can be inserted into the first accommodating cavity of the water distributor 10. The outer peripheral edge of the first water distributor 30 is folded downward to form a second folding edge 33, and a first annular sealing groove 34 is arranged on the second folding edge 33 in the circumferential direction, which is used to accommodate a sealing ring.

[0074] The upper part of the center pipe 20 is provided with a first limiting part 21, and when the first water distributor 30 is sleeved on the center pipe 20, the first water distributor 30 abuts against the first limiting part 21, so as to limit the first water distributor 30. The upper part of the center pipe 20 is provided with a first sealing groove 22 for accommodating a sealing ring. The first sealing groove 22 is located above the first limiting part 21.

[0075] The water distribution device further comprises a flow guide 40 and a second water distributor 50. The flow guide 40 is arranged at the bottom end of the central pipe 20, and has a flow guide cavity 41 which is in communication with the central pipe 20 and can guide the water flow in the flow guide cavity 41 to spread to the periphery. The second water distributor 50 is arranged on the upper side of the flow guide 40, and a plurality of second water distribution holes 51 are formed on the second water distributor 50. The aperture of the end of the second water distribution hole 51 close to the resin layer is smaller than the particle size of the resin particles. By arranging the flow guide 40, when the water flow in the central pipe 20 flows to the flow guide cavity 41 of the flow guide 40, the flow guide cavity 41 guides the water flow in the flow guide cavity 41 to spread to the periphery, so that the water flow uniformly enters the resin layer, preventing the edge position of the resin layer from not being fully contacted with the water flow and avoiding the formation of a blind area. Similarly, when the water flow in the resin layer flows along the flow guide 40 to the central pipe 20, the water flow converges from the periphery of the flow guide 40 to the middle, so that the water flow is fully contacted with the resin layer.

[0076] Referring to Figure 8 , Figures 14 to 16 , the flow guide 40 comprises a flow guide plate 42. A flow guide opening 421 is formed in the middle of the flow guide plate 42. The outer peripheral edge of the flow guide plate 42 is folded downward to form a flow guide flange 43. The flow guide plate 42 and the flow guide flange 43 surround the flow guide cavity 41. A plurality of flow guide grooves 44 are formed on the flow guide flange 43. A plurality of first rib plates 45 are arranged on the inner wall of the flow guide cavity 41. The first rib plates 45 are arranged between the flow guide plate 42 and the flow guide flange 43 to play a reinforcing role.

[0077] In this embodiment, the flow guide 40 and the central pipe 20 are inserted into the second water distributor 50 and are in communication with each other. In other embodiments, the flow guide 40 and the central pipe 20 can be inserted and communicated with each other, and the second water distributor 50 can be sleeved on the central pipe 20.

[0078] Exemplarily, a mounting boss 46 is arranged on the top of the flow guide plate 42 and around the periphery of the flow guide opening 421. The mounting boss 46 is used to be inserted into the second central hole 55 of the second water distributor 50. The lower end of the central pipe 20 is inserted into the second central hole 55 of the second water distributor 50. A sealing ring is arranged between the mounting boss 46 and the second central hole 55, and between the central pipe 20 and the second central hole 55.

[0079] A plurality of second rib plates 47 are arranged on the flow guide plate 42 and are spaced apart around the periphery of the mounting boss 46. The second rib plates 47 connect the mounting boss 46 and the flow guide plate 42 to play a reinforcing role.

[0080] Referring to Figure 8 , Figures 17 to 19The second water distributor 50 is coaxially arranged with the central pipe 20. The second central hole 55 of the second water distributor 50 is used for penetrating the central pipe 20 and the flow guide 40.

[0081] The flow area of the second water hole 51 can be uniform along the axial direction of the second water distributor 50, or the flow area of the second water hole 51 can gradually decrease along the axial direction of the second water distributor 50, and the end of the second water hole 51 close to the resin layer is the smallest end of the second water hole 51.

[0082] The second water distributor 50 is coaxially arranged with the central pipe 20. The second central hole 55 of the second water distributor 50 is used for penetrating the central pipe 20 and the flow guide 40.

[0083] In the embodiment, the second water distributor 50 is provided with a plurality of second water guide protrusions 52 on the surface close to the flow guide 40. The second water guide protrusions 52 extend along the radial direction of the second water distributor 50, and the second water holes 51 are arranged between adjacent second water guide protrusions 52. By arranging the second water guide protrusions 52, the circumferential flow of the water flow is reduced, and the distribution of the water flow is more uniform.

[0084] The outer peripheral edge of the second water distributor 50 is upwardly folded to form a third folded edge 53. The third folded edge 53 is provided with a second annular sealing groove 54 around the circumference, which is used for accommodating a sealing ring.

[0085] The lower part of the central pipe 20 is provided with a second limiting portion 23. When the second water distributor 50 is sleeved on the central pipe 20, the second water distributor 50 abuts against the second limiting portion 23, so as to limit the second water distributor 50. The lower part of the central pipe 20 is provided with a second sealing groove 24, which is used for accommodating a sealing ring between the central pipe 20 and the second water distributor 50. The second sealing groove 24 is located below the second limiting portion 23.

[0086] Referring to Figures 20 to 23 The embodiment also provides a water softener, which comprises a resin tank 100 and a water distribution device. The resin tank 100 comprises a first water inlet 101 and a second water inlet 102. The water distribution device is arranged in the resin tank 100. One end of the first water inlet 101 is opposite to the water inlet 12. The second water inlet 102 is communicated with the central pipe 20. In some embodiments, the first water inlet 101 is used for water inlet. The water inlet flow impacts the water inlet 12. The second water inlet 102 is used for water outlet. In some embodiments, the first water inlet 101 is used for water outlet. The second water inlet 102 is used for water inlet into the central pipe 20.

[0087] The resin layer is arranged between the first water distributor 30 and the second water distributor 50. A sealing ring is arranged between the outer periphery of the first water distributor 30 and the inner wall of the resin tank 100, and a sealing ring is arranged between the outer periphery of the second water distributor 50 and the inner wall of the resin tank 100, so as to prevent resin particles from entering the upper side of the first water distributor 30 or the lower side of the second water distributor 50.

[0088] When softening the water, as shown in FIG. 1, the water enters the first water inlet 101, the water flow impacts the water inlet 12, flows along the water-facing surface 11 on the water distributor 10, and flows out of the water distributor 10 through the water guide hole 131, and then flows into the resin layer through the first water distribution hole 31 on the first water distributor 30. The water flow flows downward along the resin layer, removes the hardness ions in the water, and then gathers from the periphery to the center of the flow guide 40 after passing through the second water distributor 50, and then flows out of the second water inlet 102 through the center pipe 20. Figure 21

[0089] Due to the impact of the water flow on the water inlet 12, the water flow at the water inlet 12 is the largest, and the water flow flows out of the water distributor 10 along the water guide channel 13 on the water-facing surface 11. Since the flow area of the water guide channel 13 gradually increases in a direction away from the water inlet 12, the water flow can flow out of the water distributor 10 more quickly at a position away from the water inlet 12, so that the water flow is more evenly distributed.

[0090] The flow guide 40 is arranged so that the water flow in the resin layer flows along the flow guide 40 to the center pipe 20, and the water flow converges from the periphery to the center of the flow guide 40, so that the water flow is fully contacted with the resin layer, and the utilization rate of the resin is ensured.

[0091] When regenerating the resin, as shown in FIG. 2, the concentrated brine flows from the second water inlet 102 to the bottom of the resin tank 100 through the center pipe 20, diffuses to the periphery through the flow guide cavity 41 of the flow guide 40, and then flows to the resin layer through the second water distributor 50. The water flow flows upward along the resin layer, regenerates the resin, and then flows out of the first water inlet 101 after passing through the first water distributor 30 and the water distributor 10. If the flow guide 40 is not arranged, the concentrated brine cannot diffuse to the corner position of the resin layer or needs more time to diffuse to the corner position, resulting in that part of the resin layer cannot be fully regenerated or more concentrated brine is needed, resulting in waste of salt. Therefore, by arranging the flow guide 40, the salt used for fully regenerating the resin is less, the regeneration efficiency is better, the regeneration effect is better, and the water production of the water softener is more. Figure 22

[0092] Figure 23 ​​​As shown, the top of the resin tank 100 is provided with a plurality of positioning protrusions 103 on the inner wall for inserting into the positioning groove 15 of the water distributor 10. The top of the resin tank 100 is provided with a limiting protrusion 104 on the inner wall for inserting into the center hole 16 of the water distributor 10, the limiting protrusion 104 is sleeved on the outer periphery of the center tube 20 and a sealing ring is arranged between the limiting protrusion 104 and the center tube 20.
