ABSTRACT:
An aerating nozzle assembly has at least one aerating nozzle, and each aerating nozzle has a body, an annular air casing and at least one air tube. The body is tubular and has a channel and a constriction. The constriction is formed around the body and has multiple air holes formed through the constriction and communicating with the channel. The annular air casing is hollow and is mounted around the air holes in the constriction and has an air chamber, an annular surface and at least one air supply hole formed through the annular surface. The at least one air tubes are mounted securely respectively in the air supply holes. Accordingly, the air holes around the constriction allow air to be drawn into the liquid and more completely and homogenously aerate the liquid.
