AERATION DEVICE

摘要

Aeration device includes a hollow casing having a motor therein; a mixing unit formed on front side of the casing and having a discharge hole formed in radial direction and an intake hole formed on front thereof; an impeller located inside the mixing unit and coupled to a driving shaft of the motor, the driving shaft extended to the mixing unit, so as to be rotated with the driving shaft, to generate flow in outward radial direction upon rotation, an air inflow unit having one side end located in front of the impeller and serving as an air inflow pipe for introducing air to the mixing unit; and an auxiliary intake unit located on front side of the impeller to be rotated with the driving shaft of the motor and inserted into the air inflow unit to allow fluid in the air inflow unit to flow backward upon rotation.

1. An aeration device comprising:
a hollow casing (91) having a motor (913) mounted therein; a mixing unit (92) formed on the front side of the casing (91) and having a discharge hole (923) formed in a radial direction and an intake hole (941) formed on the front thereof; an impeller (93) located inside the mixing unit (92) and coupled to a driving shaft (9135) of the motor (913), the driving shaft (9135) being extended to the mixing unit (92), in such a manner as to be rotated unitarily with the driving shaft (9135), to generate a flow in an outward radial direction upon the rotation; an air inflow unit (96) having one side end portion located in front of the impeller (93) and serving as an air inflow pipe for introducing air to the mixing unit (92); and an auxiliary intake unit (99) located on the front side of the impeller (93) in such a manner as to be rotated unitarily with the driving shaft (9135) of the motor (913) and adapted to be inserted into the air inflow unit (96) in such a manner as to allow s fluid in the air inflow unit (96) to flow backward upon the rotation.
