[0021] The technical scheme in the utility model embodiment will be described clearly and completely below in conjunction with the drawings in the utility model embodiment, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment.

[0022] Refer to Figures 1-4A self-cleaning, anti-clogging disc-type microporous aerator includes an air inlet pipe 1, a connecting pipe 2 welded to the top of the air inlet pipe 1, an mounting plate 3 welded to the top of the connecting pipe 2, an air chamber 5 inside the mounting plate 3, a sealing cover 4 on the top of the mounting plate 3, multiple slots 6 on the outer circumference of the mounting plate 3, multiple locking blocks 7 welded to the bottom of the sealing cover 4, the locking blocks 7 engaging with the slots 6, and multiple air outlet holes 8 on the top of the sealing cover 4. Gas enters from the air inlet pipe 1, then enters the air chamber 5 through the connecting pipe 2, and is discharged from the air outlet holes 8 for aeration. A handle 9 is welded to the top outer wall of the sealing cover 4, and an anti-slip sleeve is adhered to the outer wall of the handle 9 to facilitate the operation of the sealing cover 4. A rubber sealing gasket 15 is engaged at the bottom of the sealing cover 4 to improve the sealing performance between the sealing cover 4 and the mounting plate 3.

[0023] The bottom of the mounting plate 3 is provided with an insertion hole. A connecting ring 10 is welded to the inner circumference of the insertion hole. A rotating rod 11 is rotatably inserted into the connecting ring 10. Multiple fan blades 12 are fixed to the bottom end of the rotating rod 11 by bolts. The fan blades 12 are located inside the air intake pipe 1. Multiple connecting plates 13 are fixed to the outer wall of the rotating rod 11 by bolts. Brushes 14 are fixed to the connecting plates 13 by bolts. Under the flow of gas, the fan blades 12 are driven to rotate, thereby driving the rotating rod 11 to rotate, which in turn drives the brushes 14 to brush on the top and bottom of the sealing cover 4, thus cleaning the sealing cover 4 and preventing the air outlet 8 from being blocked. The multiple brushes 14 are in contact with the top and bottom of the sealing cover 4 respectively.

[0024] The working principle of this embodiment is as follows: When in use, gas enters from the air inlet pipe 1, then enters the air chamber 5 through the connecting pipe 2, and is discharged from the air outlet 8 for aeration. The flow of gas drives the fan blade 12 to rotate, thereby driving the rotating rod 11 to rotate, which in turn drives the brush 14 to brush on the top and bottom of the sealing cover 4, thus cleaning the sealing cover 4 and preventing the air outlet 8 from being blocked.

[0025] When it is necessary to disassemble or assemble the mounting plate 3 and the sealing cover 4, lift the handle 9 upward to move the sealing cover 4 upward, thereby separating the locking block 7 from the locking groove 6, so that the sealing cover 4 can be disassembled. When installing, hold the handle 9 to place the sealing cover 4 on the mounting plate 3, and make the locking block 7 engage with the locking groove 6 to fix the sealing cover 4.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
