PROBLEM TO BE SOLVED: To provide an air blower that can send sufficient air quantity in a wide range even when the size is reduced.SOLUTION: An air blower includes: a suction port for taking in air; high-pressure air generation means for generating high-pressure air by compressing the air taken in from the suction port; a blowout port for blowing out the high-pressure air; a first air course for communicating the suction port, the high-pressure air generation means and the blowout port with each other; a plurality of induction air suction ports for sucking air induced by the air blown out from the blowout port; an induction air mixing section for mixing air sucked from the plurality of induction air suction ports; an induction air blowout port for blowing out air mixed by the induction air mixing section; a second air course for communicating the induction air suction port, the induction air mixing section and the induction air blowout port with each other; an inside blowout port for blowing out the high-pressure air on the inner side of the blowout port; and a third air course for communicating the high-pressure air generation means and the inside blowout port with each other.SELECTED DRAWING: Figure 3 |
