<p>Disclosed is an aeration device, in which a fed amount of air can be controlled, and an aeration function can be improved by enhancing miscibility of water and air. The aeration device comprises: a hollow casing having a motor installed therein; a mixing unit installed in a front side of the casing, including a discharge hole formed in a radius direction, and having a drive shaft of the motor penetrating and extending from a rear side to a front side thereof; an impeller formed in the mixing unit to be rotated, and coupled with the drive shaft to generate a flow in a radius direction of the mixing unit; an absorbing housing formed in a front side of the mixing unit and having multiple absorbing holes formed therein; and an air feeding unit having an extending pipe unit penetrating through the absorbing housing from a front side to a rear side, and extending towards the impeller. The air feeding unit includes an air adjusting valve for controlling an amount of air flowing through the air feeding unit. Accordingly, a fed amount of air can be controlled so that aeration can be effectively performed and miscibility of water and air is enhanced, thereby improving an aeration function.</p> |
