[0025] Example

[0026] In order to solve the problem that the aeration device in the prior art cannot remove dirt from the air outlet 11, thereby affecting the subsequent aeration, the present application discloses an aeration device that is easy to clean, comprising:

[0027] An aeration pipe 10 with both ends closed; a plurality of air outlet holes 11 are provided on the side surface of the aeration pipe 10;

[0028] The airbag column 20 is disposed at the inner center of the aeration tube 10;

[0029] A flexible plate 30, the flexible plate 30 is attached to the outer ring of the airbag column 20, and a plurality of ejector protrusions 31 corresponding to the air outlet holes 11 are formed on the flexible plate 30;

[0030] During specific use, the ejector protrusion 31 can pass through the air outlet hole 11 by inflating air into the air bag column 20, so that the dirt blocking the air outlet hole 11 can be automatically cleaned.

[0031] In this embodiment, a through hole 12 is opened at the upper end of the aeration tube 10, and the air inlet and outlet pipes 21 of the airbag column 20 extend from the through hole 12.
