Air outlet housing for building air conditioning - has an electrically vibrated rubber membrane opposite an opening to agitate the air and forcibly eject it

摘要

The air outlet housing is parallelepipedal (1) with an opening (9) in the front (3). The cube contains an air chamber (2), and the back (4) consists of a rubber membrane with an agitator rod and soft iron cored electric coil. The rod is activated by an electric current passing through the coil, and this vibrates the membrane causing an impulse whirling of the air inside the chamber, forcing it out through the opening along the axis (18). ADVANTAGE - Can bring a supply of air over long distances without mixing it with ambient air.
