[0048] The technical solutions of the utility model are further illustrated below in combination with the drawings and through specific embodiments.

[0049] Referring to Figures 1 to 21 The 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 first bottom support 24, and the first bottom support 24 has a lifting cavity 241 arranged in a ring shape. The water inlet 11 is in communication with the lifting cavity 241, and water in the lifting cavity 241 can overflow from the upper end of the lifting cavity 241. The water flowing into the waterway valve 10 from the water inlet 11 flows into the lifting cavity 241 and accumulates in the lifting cavity 241. When the water level is higher than the upper end of the lifting cavity 241, the water overflows from the upper end of the lifting cavity 241. By arranging the lifting cavity 241, the water flow is converged, so that the water flow is uniformly distributed in the lifting cavity 241, and the water flow is uniformly dispersed in all directions by means of the overflow from the upper end.

[0050] The lifting cavity 241 is arranged in a ring shape and can be a continuous ring or a segmented ring. For example, a plurality of partition plates are arranged in the lifting cavity 241 at intervals in the circumferential direction, and the partition plates divide the lifting cavity 241 into a plurality of arc-shaped cavities.

[0051] In order to facilitate smooth overflow of the first bottom support 24, the top end of the first bottom support 24 can be arranged in an open manner and spaced apart from the waterway valve 10. Figure 2 The arrow shows the direction of the water flow. Alternatively, overflow holes can be formed in the first bottom support 24 for overflow.

[0052] The first bottom support 24 comprises a bottom plate 243 and a side plate 244. The side plate 244 is arranged in an inverted conical shape around the circumference of the bottom plate 243, and the bottom plate 243 and the side plate 244 enclose the lifting cavity 241. By arranging the side plate 244 in an inverted conical shape, the water flow can be more outwardly dispersed when overflowing from the upper end, which facilitates uniform distribution of the water flow.

[0053] The first bottom support 24 further comprises a first reinforcing rib plate 245 arranged in the lifting cavity 241 and located on the bottom plate 243. Alternatively, the first bottom support 24 further comprises a second reinforcing rib plate 246 arranged in the lifting cavity 241 and located at the junction of the bottom plate 243 and the side plate 244. The first reinforcing rib plate 245 and the second reinforcing rib plate 246 can both increase the structural strength. For example, the first reinforcing rib plate 245 is arranged in a ring shape.

[0054] The first bottom support 24 can be detachably connected with the waterway valve 10, facilitating installation, disassembly or replacement. For example, the first bottom support 24 is clamped or screwed with the waterway valve 10, facilitating installation and disassembly. For example, the lifting cavity 241 is internally provided with a connecting portion, which is screwed with the waterway valve 10.

[0055] 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 communicated with the water outlet 12, the first water distribution assembly 20 is sleeved on the upper portion of the central pipe 30, and the first bottom support 24 is annularly arranged around the central pipe 30. Specifically, the central pipe 30 is arranged through the bottom plate 243, and a sealing ring can be arranged between the central pipe 30 and the bottom plate 243 to prevent water leakage at the bottom of the lifting cavity 241. The first bottom support 24 can also be connected with the central pipe 30 to fix the first bottom support 24.

[0056] In some embodiments, the first water distribution assembly 20 comprises a first water collecting and distributing portion 23 and a first bottom support 24.

[0057] The first water collecting and distributing portion 23 is arranged on the upper side of the first bottom support 24, and has a first water collecting cavity 231 and a plurality of first water passing holes 232 communicated with the first water collecting cavity 231. The first water collecting cavity 231 is communicated with the water inlet 11, and the plurality of first water passing holes 232 guide the water in the first water collecting cavity 231 to flow outwards and into the lifting cavity 241. The first water collecting and distributing portion 23 serves to uniformly distribute the water flowing downwards.

[0058] The lifting cavity 241 is annularly arranged, i.e. the lifting cavity 241 is annularly arranged around the periphery of the first water collecting and distributing portion 23, and the first water passing holes 232 are communicated with the lifting cavity 241, so that the water flow can be uniformly distributed in the lifting cavity 241, and finally overflow from the top of the first bottom support 24.

[0059] In this embodiment, the lower end of the first water collecting and distributing portion 23 is inserted into the lifting cavity 241, so that the water flowing out of the first water collecting and distributing portion 23 can enter the lifting cavity 241, i.e. be intercepted by the first bottom support 24, to be uniformly distributed in the lifting cavity 241. Therefore, the first bottom support 24 serves to collect and uniformly distribute the water flow.

[0060] The first bottom support 24 is connected with the first water collecting and distributing portion 23. The first bottom support 24 is detachably connected with the first water collecting and distributing portion 23, facilitating installation, disassembly or replacement. Preferably, the first bottom support 24 is clamped with the first water collecting and distributing portion 23, which can be clamped by buckles. Specifically, the first bottom support 24 is provided with a plurality of third clamping protrusions 242, and the first water collecting and distributing portion 23 is provided with a plurality of third clamping grooves 236. During installation, the third clamping protrusions 242 are inserted into the third clamping grooves 236 to realize clamping.

[0061] Exemplarily, the third clamping protrusion 242 is arranged in the lifting cavity 241 and on the bottom plate 243, and the third clamping groove 236 is arranged at the bottom of the first water distribution 23. Exemplarily, the third clamping protrusion 242 is arranged on the first reinforcing rib plate 245.

[0062] The first water distribution 23 comprises a first inner wall plate 234 and a first outer wall plate 235, and 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 a plurality of 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.

[0063] The first water passing holes 232 extend in the axial direction of the first outer wall plate 235 in a strip shape, and the plurality of first water passing holes 232 are arranged at intervals in the circumferential direction of the first outer wall plate 235. In this embodiment, the first outer wall plate 235 is in the shape of an inverted cone, and the first inner wall plate 234 is arranged in a ring shape around the central pipe 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 outward, facilitating the water flowing out of the water collecting cavity 221 to enter the first water collecting cavity 231.

[0064] The first water distribution 23 can be detachably connected with the waterway valve 10, facilitating installation, disassembly or replacement. Exemplarily, the first water distribution 23 is connected with the waterway valve 10 by clamping or screwing, facilitating installation and disassembly.

[0065] The first water distribution 23 not only can distribute the water flowing from above outward, but also can uniformly distribute the water and prevent the resin particles of the resin layer from entering the upper side of the first water distribution 23. Exemplarily, the diameter of the first water passing hole 232 is smaller than the diameter of the resin particles.

[0066] In some embodiments, the first water distribution assembly 20 comprises a first bottom support 24 and a water distributor 21.

[0067] The water distributor 21 is arranged on the upper side of the first bottom support 24, 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 outlet holes 213 are arranged at intervals on the water guide surface 212. The lifting cavity 241 is in communication with the water outlet holes 213.

[0068] 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 outlet holes 213 on the water guide surface 212. By arranging the water guide surface 212, the water flow is more uniformly distributed in the water distribution cavity 211.

[0069] 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.

[0070] 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 provided with water guide surfaces 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 by means of the water guide surfaces 212 and then flows to the low point. In the process of flowing in the water distribution cavity 211, the water flows out from the water outlet holes 213 on the water guide surfaces 212.

[0071] 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.

[0072] 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. It can be that the interval between adjacent water outlet holes 213 is unchanged, and the diameter of each water outlet hole 213 increases in the direction from the high point to the low point. It can also be that the diameter of each water outlet hole 213 is unchanged, and the interval between adjacent water outlet holes 213 gradually decreases in the direction from the high point to the low point.

[0073] 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. The water distributor 21 is detachably connected with the waterway valve 10, which is convenient for installation, disassembly or replacement. Specifically, the connection can be clamping, threaded connection or bolt connection. In this embodiment, the mounting column 13 is arranged on the waterway valve 10, the threaded hole is formed in the mounting column 13, the mounting hole 215 is formed on the water distributor 21, and the bolt is threadedly connected with the threaded hole on the waterway valve 10 through the mounting hole 215 on the water distributor 21.

[0074] In some embodiments, the first water distribution assembly 20 includes a first bottom support 24 and a first water collecting member 22.

[0075] The first flow converging member 22 is arranged on the upper side of the first bottom support 24, the lower end opening of the first flow converging member 22 is smaller than the top end opening of the lifting cavity 241, the first flow converging member 22 has a flow converging cavity 221, the water flowing into the water inlet 11 flows into the lifting cavity 241 through the flow converging cavity 221, and the cross-sectional area of the flow converging cavity 221 gradually decreases in the direction from top to bottom. So that the water flow has a larger inlet and a smaller outlet when flowing through the flow converging cavity 221, thereby buffering the water flow and facilitating the subsequent uniform distribution of the water flow.

[0076] The lower end opening of the first flow converging member 22 is smaller than the top end opening of the lifting cavity 241, so that the water flowing out of the flow converging cavity 221 can enter the lifting cavity 241. In the direction from top to bottom, the cross-sectional area of the lifting cavity 241 gradually increases, which is more convenient for receiving water flowing down from above.

[0077] In this embodiment, the lower end of the first flow converging member 22 is inserted into the lifting cavity 241, that is, the lower edge of the first flow converging member 22 is lower than the upper edge of the first bottom support 24, so that the water flowing out of the flow converging cavity 221 can enter the lifting cavity 241, preventing the water flowing down from the flow converging cavity 221 from splashing out of the top of the lifting cavity 241.

[0078] The first flow converging member 22 can be detachably connected with the waterway valve 10, which is convenient for installation, disassembly or replacement. Exemplarily, the first flow converging member 22 is clamped or threaded with the waterway valve 10, which is convenient for installation and disassembly.

[0079] In the direction from top to bottom, the cross-sectional area of the flow converging cavity 221 gradually decreases, the flow converging cavity 221 is in the shape of an inverted cone, the first flow converging member 22 is sleeved on the central pipe 30, that is, the central pipe 30 is inserted into the flow converging cavity 221, and an annular cavity with a gradually decreasing cross-sectional area from top to bottom is formed between the inner wall of the flow converging cavity 221 and the outer wall of the central pipe 30, which plays a role in converging the water flow and to some extent, plays a role in uniform water flow.

[0080] The first flow converging member 22 includes a water guiding edge 226, which is located below the water inlet 11 and arranged on the top of the flow converging cavity 221 to guide the water flow into the flow converging cavity 221. The arrangement of the water guiding edge 226 plays a buffering role for the water flowing into the water inlet 11, so that the water flow flows into the flow converging cavity 221 at a slow speed, thereby achieving the effect of uniform water flow.

[0081] The water guiding edge 226 is arranged in the shape of a ring, which is convenient for processing and production and convenient for installation. Exemplarily, the inner periphery of the water guiding edge 226 is connected with the flow converging cavity 221, and an arc surface is arranged at the connection position to guide the water flow and make the water flow smooth. Exemplarily, the water guiding edge 226 is arranged obliquely, and the lower end of the water guiding edge 226 is inserted into the flow converging cavity 221 to guide the water flow and make the water flow smooth.

[0082] In some embodiments, the first water distribution assembly 20 comprises the first base 24, the first distributor 23 and the water distributor 21. The water distributor 21, the first distributor 23 and the first base 24 are arranged in sequence from top to bottom.

[0083] The first water collection cavity 231 is located below the water outlet hole 213 and communicates with the water outlet hole 213. The plurality of first water passing holes 232 guide the water in the first water collection cavity 231 to flow outwards into the lifting cavity 241. The first distributor 23 has the function of dispersing the water flowing from above outwards, so as to uniformly distribute the water.

[0084] The first distributor 23 and the water distributor 21 are detachably connected, facilitating installation, disassembly or replacement. For example, the first distributor 23 and the water distributor 21 are snap-connected or screw-connected, facilitating installation and disassembly.

[0085] In some embodiments, the first water distribution assembly 20 comprises the first base 24, the first distributor 23 and the first water collector 22. The first water collector 22, the first distributor 23 and the first base 24 are arranged in sequence from top to bottom.

[0086] The lower edge of the first water collector 22 is lower than the upper edge of the first distributor 23, i.e. the lower end of the first water collector 22 is inserted into the first water collection cavity 231, so that the water flowing out of the water collection cavity 221 can enter the first water collection cavity 231. The lower end of the first distributor 23 is inserted into the first base 24, so that the water flowing out of the first distributor 23 can enter the first base 24.

[0087] The first distributor 23 and the first water collector 22 are detachably connected, facilitating installation, disassembly or replacement. Preferably, the first distributor 23 and the first water collector 22 are snap-connected, which can be snap-connected through buckles. Alternatively, the first distributor 23 can be detached from the first water collector 22 by rotating relative to the first water collector 22. For example, the first distributor 23 and the first water collector 22 are screw-connected. For example, the upper end of the first distributor 23 is inserted into the mounting cavity 224 on the outer periphery of the first water collector 22. The inner wall of the mounting cavity 224 is provided with a plurality of second clamping protrusions 225, and the outer wall of the first distributor 23 is provided with a plurality of second clamping grooves 233. When mounting, the upper end of the first distributor 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. By rotating the first distributor 23, the second clamping protrusions 225 are inserted into the second clamping grooves 233.

[0088] In some embodiments, the first water distribution assembly 20 comprises the first base 24, the first water collector 22 and the water distributor 21. The water distributor 21, the first water collector 22 and the first base 24 are arranged in sequence from top to bottom.

[0089] The water collecting cavity 221 is located below the water outlet hole 213 and communicates with the water outlet hole 213. The water collecting cavity 221 is located above the first bottom support 24 and communicates with the lifting cavity 241. Therefore, the water collecting cavity 221 communicates the water outlet hole 213 and the lifting cavity 241. In the direction from top to bottom, the cross-sectional area of the water collecting cavity 221 gradually decreases. The first water collecting member 22 is used to collect the water flowing out of the water distributor 21, so as to facilitate subsequent uniform distribution.

[0090] The first water collecting member 22 is detachably connected with the water distributor 21, so as to facilitate installation, disassembly or replacement. Preferably, the first water collecting member 22 is clamped with the water distributor 21, which can be clamped by buckles. Alternatively, the first water collecting member 22 can be detached from the water distributor 21 by rotating relative to the water distributor 21. For example, the first water collecting member 22 is threadedly connected with the first water distributing member 23.
