[0045] The technical scheme of the present application is further illustrated below by combining the drawings and through specific embodiments.

[0046] Referring to Figures 1 to 19 The present embodiment provides a water distribution device, which comprises a waterway valve 10 and a first water distribution assembly 20 arranged on the lower side of the waterway valve 10. The waterway valve 10 has a water inlet 11 and a water outlet 12. The first water distribution assembly 20 comprises a water distributor 21, and the water distributor 21 has a water distribution cavity 211. The bottom surface of the water distribution cavity 211 is provided with a high point and a low point. The high point is opposite to the water inlet 11. A downwardly inclined water guide surface 212 is arranged between the high point and the low point to guide the water flow from the high point to the low point. A plurality of water outlets 213 are arranged on the water guide surface 212 at intervals.

[0047] The water entering the water inlet 11 of the waterway valve 10 impacts the high point of the water distribution cavity 211 and flows to the low point by means of the water guide surface 212. In the process of flowing in the water distribution cavity 211, the water flow flows out from the water outlets 213 on the water guide surface 212. By arranging the water guide surface 212, the water flow is more evenly distributed in the water distribution cavity 211.

[0048] The water inlet 11 of the waterway valve 10 is eccentrically arranged relative to the water distributor 21, and the high point of the bottom surface of the water distribution cavity 211 is located directly below the water inlet 11. Specifically, the water distributor 21 has a first axis, and the water inlet 11 is eccentric relative to the first axis. The shape of the water inlet 11 can be set according to actual needs. In this embodiment, the water inlet 11 extends in an arc shape.

[0049] The water distribution device further comprises a central pipe 30, the waterway valve 10 is arranged at the top end of the central pipe 30, the top end of the central pipe 30 is in communication with the water outlet 12, the first water distribution assembly 20 is sleeved on the upper portion of the central pipe 30, the water distribution cavity 211 is arranged in an annular shape around the central pipe 30, and the two sides of the high point are both provided with a water guide surface 212. The water entering the water inlet 11 of the waterway valve 10 impacts the high point of the water distribution cavity 211 and flows to the two sides of the high point and to the low point by means of the water guide surface 212. In the process of flowing in the water distribution cavity 211, the water flows out from the water outlet hole 213 on the water guide surface 212.

[0050] The interval between the high point and the low point is greater than or equal to 150 degrees and less than or equal to 180 degrees, so that the water guide surface 212 can extend for a certain length, which is beneficial to the uniform distribution of water flow. Preferably, the interval between the high point and the low point is equal to 180 degrees, and the slopes of the water guide surfaces 212 arranged on the two sides of the high point can be the same, so that the water flow uniformly flows to the two sides from the high point.

[0051] Since the high point is directly opposite the water inlet 11 of the waterway valve 10, the water flow at the high point is relatively large. Preferably, the flow area of the water outlet hole 213 gradually increases in the direction from the high point to the low point, which further ensures the uniform distribution of water flow in the water distribution cavity 211. Alternatively, the interval between adjacent water outlet holes 213 remains unchanged, and the diameter of each water outlet hole 213 increases in the direction from the high point to the low point. Alternatively, the diameter of each water outlet hole 213 remains unchanged, and the interval between adjacent water outlet holes 213 gradually decreases in the direction from the high point to the low point.

[0052] The shape of the water outlet hole 213 can be set according to actual needs. In this embodiment, the water outlet hole 213 is a long hole and extends in the radial direction of the water distributor 21, so as to ensure a large water outlet area and make full use of the space of the water distribution cavity 211.

[0053] The water distributor 21 and the waterway valve 10 are detachably connected, which is convenient for installation, disassembly or replacement. Specifically, the connection can be clamping, threaded connection or bolt connection. In this embodiment, the waterway valve 10 is provided with a mounting column 13, a threaded hole is formed in the mounting column 13, and the water distributor 21 is provided with a mounting hole 215. A bolt is threadedly connected through the mounting hole 215 on the water distributor 21 and the threaded hole on the waterway valve 10.

[0054] In some embodiments, the first water distribution assembly 20 comprises a water distributor 21 and a first water collector 23.

[0055] Referring to Figures 1 to 4 , and in conjunction with Figures 11 to 14 , the first water collector 23 has a first water collecting cavity 231 and a plurality of first water passing holes 232 in communication with the first water collecting cavity 231. The first water collecting cavity 231 is located below the water outlet hole 213 and in communication with the water outlet hole 213. The plurality of first water passing holes 232 guide the water in the first water collecting cavity 231 to flow outwards. The first water collector 23 functions to disperse the water flowing from above outwards, with the purpose of evenly distributing the water.

[0056] The first water collector 23 comprises a first inner wall plate 234 and a first outer wall plate 235. The first inner wall plate 234 and the first outer wall plate 235 enclose the first water collecting cavity 231. The first outer wall plate 235 is provided with the first water passing holes 232. The water flowing from above enters the first water collecting cavity 231 between the first inner wall plate 234 and the first outer wall plate 235, and then flows out from the plurality of first water passing holes 232. The first inner wall plate 234 has a certain height to prevent the water in the first water collecting cavity 231 from overflowing from the top end of the first inner wall plate 234. A sealing ring can be arranged between the first inner wall plate 234 and the center tube 30.

[0057] The first water passing holes 232 extend in the axial direction of the first outer wall plate 235 in the form of long strips. The plurality of first water passing holes 232 are arranged at intervals in the circumferential direction of the first outer wall plate 235. In the present embodiment, the first outer wall plate 235 is in the form of an inverted cone, and the first inner wall plate 234 is arranged in the form of a ring around the center tube 30. The shapes of the first outer wall plate 235 and the first inner wall plate 234 are arranged such that the top of the first water collecting cavity 231 is open outwards, facilitating the water flowing from above to enter the first water collecting cavity 231.

[0058] The first water collector 23 is detachably connected to the water distributor 21, facilitating installation, disassembly or replacement. Exemplarily, the first water collector 23 is snap-connected or screw-connected to the water distributor 21, facilitating installation and disassembly.

[0059] The first water collector 23 not only disperses the water flowing from above outwards and evenly distributes the water, but also prevents the resin particles of the resin layer from entering the upper part of the first water collector 23. Exemplarily, the diameter of the first water passing holes 232 is smaller than the diameter of the resin particles.

[0060] In some embodiments, the first water distribution assembly 20 comprises the water distributor 21, the first water collector 23 and a first water collecting member 22.

[0061] Referring to Figures 1 to 4 , and in conjunction with Figure 9 and Figure 10The first flow collector 22 is arranged between the water distributor 21 and the first water collecting device 23. The lower end opening of the first flow collector 22 is smaller than the top end opening of the first water collecting cavity 231. The first flow collector 22 has a flow collecting cavity 221. The water flowing out of the water outlet hole 213 flows into the first water collecting cavity 231 through the flow collecting cavity 221, that is, the flow collecting cavity 221 communicates the water outlet hole 213 and the first water collecting cavity 231. In the direction from top to bottom, the cross-sectional area of the flow collecting cavity 221 gradually decreases, so that the flow inlet is larger and the flow outlet is smaller during the water flow through the flow collecting cavity 221, thereby buffering the water flow and facilitating the subsequent uniform distribution.

[0062] The lower end opening of the first flow collector 22 is smaller than the top end opening of the first water collecting cavity 231, which facilitates the water flowing out of the first flow collector 22 to enter the first water collecting cavity 231. Exemplarily, the lower end of the first flow collector 22 is inserted into the first water collecting cavity 231, so that the water flowing out of the flow collecting cavity 221 can enter the first water collecting cavity 231.

[0063] The first flow collector 22 and the water distributor 21 are detachably connected, which facilitates installation, disassembly or replacement. Preferably, the first flow collector 22 and the water distributor 21 are clamped, which can be clamped by buckles. Alternatively, the first flow collector 22 can be detached from the water distributor 21 by rotating relative to the water distributor 21. Exemplarily, the first water collecting device 23 and the first flow collector 22 are threadedly connected. Exemplarily, the upper end of the first flow collector 22 is inserted into the lower end of the water distributor 21. The inner wall of the water distributor 21 is provided with a plurality of first clamping protrusions 214, and the outer wall of the first flow collector 22 is provided with a plurality of first clamping grooves 222. When installing, the upper end of the first flow collector 22 is inserted into the lower end of the water distributor 21, so that the first clamping grooves 222 are located on one side of the first clamping protrusions 214. By rotating the first flow collector 22, the first clamping protrusions 214 are inserted into the first clamping grooves 222. When disassembling, by rotating the first flow collector 22, the first clamping protrusions 214 are separated from the first clamping grooves 222, so that the first flow collector 22 can be pulled out of the lower end of the water distributor 21.

[0064] A limiting protrusion 223 is arranged on the outer wall of the first flow collector 22. When the upper end of the first flow collector 22 is inserted into the lower end of the water distributor 21, the limiting protrusion 223 abuts against the lower end of the water distributor 21 to limit the position, so that the first clamping protrusions 214 can be inserted into the first clamping grooves 222 by rotating the first flow collector 22, thereby ensuring the stable connection between the first flow collector 22 and the water distributor 21.

[0065] In the direction from top to bottom, the cross-sectional area of the converging cavity 221 gradually decreases, the converging cavity 221 is in the shape of an inverted cone, the first converging member 22 is sleeved on the central pipe 30, that is, the central pipe 30 is inserted into the converging cavity 221, and the inner wall of the converging cavity 221 and the outer wall of the central pipe 30 form an annular cavity with a gradually decreasing cross-sectional area from top to bottom, which plays a role in converging water flow and to some extent, uniformly distributing water flow.

[0066] The first converging member 22 includes a water guide edge 226, which is located below the water inlet 11 and is arranged at the top of the converging cavity 221 to guide the water flow into the converging cavity 221. The arrangement of the water guide edge 226 plays a buffering role for the water entering the water inlet 11, so that the water flow slows down into the converging cavity 221, achieving the effect of uniform water flow.

[0067] The water guide edge 226 is arranged in the shape of a ring, which is convenient for processing and production and installation. Exemplarily, the inner periphery of the water guide edge 226 is connected with the converging cavity 221, and an arc surface is arranged at the connection position to guide the water flow to flow smoothly. Exemplarily, the water guide edge 226 is arranged to be inclined, and the lower end of the water guide edge 226 is inserted into the converging cavity 221 to guide the water flow to flow smoothly.

[0068] The first distribution 23 is detachably connected with the first converging member 22, which is convenient for installation, disassembly or replacement. Preferably, the first distribution 23 is clamped with the first converging member 22, which can be clamped by a buckle. Alternatively, the first distribution 23 can be detached from the first converging member 22 by rotating relative to the first converging member 22. Exemplarily, the first distribution 23 is threadedly connected with the first converging member 22. Exemplarily, the upper end of the first distribution 23 is inserted into the mounting cavity 224 of the outer periphery of the first converging member 22, a plurality of second clamping protrusions 225 are arranged on the inner wall of the mounting cavity 224, and a plurality of second clamping grooves 233 are arranged on the outer wall of the first distribution 23. When mounting, the upper end of the first distribution 23 is inserted into the mounting cavity 224, so that the second clamping grooves 233 are located on one side of the second clamping protrusions 225, and the second clamping protrusions 225 are inserted into the second clamping grooves 233 by rotating the first distribution 23.

[0069] In some embodiments, the first water distribution assembly 20 includes the water distributor 21, the first distribution 23, and the first bottom support 24. In some embodiments, the first water distribution assembly 20 includes the water distributor 21, the first distribution 23, the first converging member 22, and the first bottom support 24.

[0070] The first bottom support 24 has a lifting cavity 241, the lower end of the first collector 23 is inserted into the lifting cavity 241, the lifting cavity 241 is annularly arranged around the periphery of the first collector 23, and the water flowing out of the first water flow hole 232 flows out of the upper end of the lifting cavity 241. The lower end of the first collector 23 is inserted into the lifting cavity 241, so that the water flowing out of the first collector 23 can enter the lifting cavity 241, that is, be intercepted by the first bottom support 24. Since the lifting cavity 241 is annularly arranged around the periphery of the first collector 23, the water flow can be uniformly distributed in the lifting cavity 241, and finally the water flow flows out of the top of the first bottom support 24. The first bottom support 24 plays a role of collecting and uniformizing the water flow.

[0071] Preferably, the lifting cavity 241 is annularly arranged around the periphery of the first collector 23. For example, the lifting cavity 241 is annularly arranged around the periphery of the first collector 23, and the lifting cavity 241 is continuously annularly arranged around the periphery of the first collector 23. For example, the lifting cavity 241 is annularly arranged around the periphery of the first collector 23, and the lifting cavity 241 is annularly arranged around the periphery of the first collector 23 in sections.

[0072] The first bottom support 24 is connected with the first collector 23, and specifically is detachably connected, so as to facilitate installation, disassembly or replacement. Preferably, the first bottom support 24 is clamped with the first collector 23. For example, the first bottom support 24 is clamped with the first collector 23 through buckling. Specifically, a plurality of third clamping protrusions 242 are arranged on the first bottom support 24, and a plurality of third clamping grooves 236 are arranged on the first collector 23. When installed, the third clamping protrusions 242 are inserted into the third clamping grooves 236 to realize clamping.

[0073] The first bottom support 24 includes a bottom plate 243 and a side plate 244, the side plate 244 is annularly arranged around the periphery of the bottom plate 243, and the bottom plate 243 and the side plate 244 enclose the lifting cavity 241. The central pipe 30 is arranged on the bottom plate 243, and a sealing ring can be arranged between the central pipe 30 and the bottom plate 243 to prevent water from leaking from the bottom of the lifting cavity 241. The third clamping protrusions 242 are arranged in the lifting cavity 241 and located on the bottom plate 243, and the third clamping grooves 236 are located at the bottom of the first collector 23.

[0074] The first bottom support 24 further includes a first reinforcing rib plate 245, the first reinforcing rib plate 245 is arranged in the lifting cavity 241 and located on the bottom plate 243, the first reinforcing rib plate 245 is annularly arranged, and the third clamping protrusions 242 are arranged on the first reinforcing rib plate 245.

[0076] In some embodiments, the second water distribution assembly 40 comprises a second water distribution device 43 having the second water collecting cavity 41 and a plurality of second water passing holes 42 which are in communication with the second water collecting cavity 41.
