DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1 to 5 shown, the present utility model provides a filtering structure for a variable-frequency water supply device, including a steady-flow compensation tank 1. A filtering mechanism 2 is provided at the inlet end of the steady-flow compensation tank 1. The filtering mechanism 2 includes a water inlet cylinder 21. The water inlet cylinder 21 is fixedly connected to the inlet end of the steady-flow compensation tank 1. A filter plate 22 is slidably connected to the bottom end inside the water inlet cylinder 21. A plurality of elastic support members 23 are provided on the outer edge of the bottom of the filter plate 22. The plurality of elastic support members 23 are evenly distributed at equal angles around the filter plate 22. An installation frame 24 is fixedly connected to the outer edge of the top of the water inlet cylinder 21 through positioning bolts 26. A plurality of card slots 25 are provided on the outer edge of the top of the water inlet cylinder 21. The outer edge of the installation frame 24 is slidably matched with the corresponding card slots 25. A cleaning member 27 for cleaning the top surface of the filter plate 22 by cooperating with the flow of water is provided at the bottom of the installation frame 24.

[0020] The supply water is introduced through the water inlet cylinder 21. The filter plate 22 can filter the impurities in the supply water. At the same time, the flowing water will drive the cleaning member 27 to clean the top surface of the filter plate 22, which can avoid the problem of filter holes being blocked due to excessive impurities accumulated on the top surface of the filter plate 22. The whole process can realize the filtration of the supply water and the automatic cleaning of the filter plate 22, without manual disassembly and cleaning, saving labor costs.

[0021] Among them, the elastic support member 23 includes a fixed seat 231. One end of the fixed seat 231 is fixedly connected to the inner wall of the water inlet cylinder 21. The other end of the fixed seat 231 is slidably connected with a slide rod 232 vertically penetrating the fixed seat 231. The top end of the slide rod 232 is fixedly connected to the filter plate 22. A stopper 233 is fixedly connected to the bottom end of the slide rod 232. A spring 234 is sleeved on the slide rod 232. The bottom end of the spring 234 abuts against the fixed seat 231, and the top end of the spring 234 abuts against the filter plate 22.

[0022] Among them, the cleaning member 27 includes a rotating shaft 271. The top end of the rotating shaft 271 is rotatably connected to the mounting bracket 24. A paddle 272 is fixedly connected to the middle of the rotating shaft 271. A plurality of scraping bars 273 are fixedly connected to the bottom end of the rotating shaft 271. The plurality of scraping bars 273 are distributed at equal angles around the rotating shaft 271, and the plurality of scraping bars 273 are in contact with the top surface of the filter plate 22. Supply water is introduced through the water inlet cylinder 21. The flowing supply water will drive the paddle 272 to rotate, which causes the rotating shaft 271 to rotate and drives all the scraping bars 273 to rotate synchronously. As a result, the scraping bars 273 slide relative to the top surface of the filter plate 22, and further, the scraping bars 273 clean the filter holes of the filter plate 22 to prevent the filter holes from being blocked.

[0023] Among them, a plurality of convex blocks 28 are fixedly connected to the outer edge of the top of the filter plate 22. The plurality of convex blocks 28 are distributed at equal angles around the filter plate 22. A rotating plate 274 is fixedly connected to the rotating shaft 271. One end of the bottom of the rotating plate 274 is fixedly connected to an arc-shaped pressing block 275. The arc-shaped pressing block 275 intermittently contacts any one of the convex blocks 28 by cooperating with the rotation of the rotating shaft 271. When the rotating shaft 271 rotates, the rotating plate 274 will rotate synchronously with the rotating shaft 271, which causes the arc-shaped pressing block 275 to intermittently contact the convex block 28. When the arc-shaped pressing block 275 contacts the convex block 28, the convex block 28 is squeezed and moves downward, which causes the filter plate 22 to move downward, so that the spring 234 is squeezed and stores potential energy. When the arc-shaped pressing block 275 separates from the convex block 28, the spring 234 releases the potential energy to make the filter plate 22 move upward. In this way, the filter plate 22 can perform reciprocating up and down vibrations, thereby improving the filtering effect on the supply water.
