[0037] like Figures 2-6 The water distribution structure shown includes an outer water distribution pipe 1 and an inner water distribution pipe 2. The inner water distribution pipe 2 is disposed inside the outer water distribution pipe 1. The upper ends of the outer water distribution pipe 1 and the inner water distribution pipe 2 are open, while the lower ends between the outer water distribution pipe 1 and the inner water distribution pipe 2 are closed, forming a guide channel 3 between them. Specifically:

[0038] The outer water distribution pipe 1 has water distribution ports 10 extending through its inner and outer sides on its pipe wall. The water distribution ports 10 are strip-shaped extending in the vertical direction, meaning that the liquid flowing between the outer water distribution pipe 1 and the inner water distribution pipe 2 can only flow out from the water distribution ports 10 of the outer water distribution pipe 1. Preferably, the water distribution ports 10 are evenly distributed on the pipe wall of the outer water distribution pipe 1, so that the liquid is evenly dispersed from the water distribution ports 10.

[0039] In a preferred embodiment of this invention: the diameter of the upper end of the external water distribution pipe 1 is larger than the diameter of its lower end, allowing liquid to flow out from different positions of the water distribution port 110 along the wall of the lower water distribution pipe 11. Specifically:

[0040] The external water distribution pipe 1 includes multiple vertically connected pipe sections 11. The diameter of the upper pipe section 11 is larger than that of the lower pipe section 11, allowing liquid that does not flow out of the water distribution port 10 of the upper pipe section 11 to flow out of the water distribution port 10 of the lower pipe section 11. Furthermore, in each pipe section 11, the diameter gradually decreases from top to bottom, allowing liquid to flow out of the water distribution port 10 along the inclined pipe wall of the pipe section 11.

[0041] Multiple reinforcing ribs 14 are provided on the outer and / or inner walls of the external water distribution pipe 1. As shown in the figure, multiple reinforcing ribs 14 are provided on both the outer and inner walls of the external water distribution pipe 1. Preferably, the multiple reinforcing ribs 14 are evenly distributed. The reinforcing ribs 14 can strengthen the connection strength of multiple pipe segments 11, thereby improving the strength and stability of the entire water distribution structure.

[0042] In another preferred embodiment of this example: a plurality of guide strips 12 are provided on the inner wall of the outer water distribution pipe 1, a guide channel 13 is formed between two adjacent guide strips 12, and a water distribution port 10 is formed on the outer side of the guide channel 13, so that liquid can flow out from the water distribution port 10 under the guidance of the guide channel 13.

[0043] The inner water distribution pipe 2 is a cylindrical pipe, coaxially arranged inside the outer water distribution pipe 1, that is, the center lines of the outer water distribution pipe 1 and the inner water distribution pipe 2 coincide. In this embodiment, the upper end of the inner water distribution pipe 2 does not extend beyond the upper end of the outer water distribution pipe 1. In the figure, the upper end of the inner water distribution pipe 2 is lower than the upper end of the outer water distribution pipe 1 by a certain distance.

[0044] In this embodiment: the outer water pipe 1 and the inner water pipe 2 are integrally formed. The lower edge of the outer water pipe 1 extends inward and then upward to form the inner water pipe 2.

[0045] The water distribution structure of this embodiment can be applied to water treatment equipment, such as water softeners and filter tanks.

[0046] Water treatment equipment typically includes a housing 40, a valve assembly 41, a central pipe 42, and a water distributor 43. The valve assembly 41 is located at the opening of the housing 40. The upper end of the central pipe 42 is connected to the valve assembly 41, and the lower end of the central pipe 42 extends into the housing 40. The water distributor 43 is fitted at the opening of the housing 40 and is fitted onto the central pipe 42. The central pipe 42 passes through the inner water distribution pipe 2, and there is a gap between the inner water distribution pipe 2 and the central pipe 42.

[0047] The water treatment equipment features low-flow brine forward flushing mode, high-flow raw water forward flushing mode, and high-flow raw water backflushing mode.

[0048] like Figure 7 As shown: In the low-flow brine forward flushing mode: the brine is flushed from top to bottom through the guide channel 3 and the water outlet 10. That is, the brine flows into the guide channel 3 through the external water distribution pipe 1 and flows out evenly from top to bottom through the guide channel 13 of the external water distribution pipe 1, which can slowly and evenly flush the filter media in the housing 30.

[0049] like Figure 8 As shown: In the high-flow-rate raw water forward flushing mode: a portion of the raw water is flushed from top to bottom through the guide channel 3 and the water outlet 10, that is, a portion of the raw water flows into the guide channel 3 through the outer water distribution pipe 1 and flows out evenly from top to bottom through the guide channel 13 of the outer water distribution pipe 1; another portion of the raw water is flushed from top to bottom through the gap between the inner water distribution pipe 2 and the central pipe 42. Due to the large water volume, rapid circulation can be achieved.

[0050] like Figure 9As shown: in the large flow raw water backwash mode: a part of raw water is washed from bottom to top through the water distribution opening 10 and the flow guide groove 3, and another part of raw water is washed from bottom to top through the gap between the inner water distribution pipe 2 and the center pipe 42, that is, contrary to the large flow raw water direct washing mode, and fast flow can also be realized.

[0051] The above examples are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable the person skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model. Any equivalent change or modification according to the spirit and essence of the utility model shall be covered within the protection scope of the utility model.
