<p><P>PROBLEM TO BE SOLVED: To provide a simple air duster which contributes to measures against environmental pollution, can be used economically over a long period, and achieves a higher function and a more compact size compared to conventional ones. <P>SOLUTION: This blower includes: a housing 5 which has a pair of openings 1, 4 and in which a flow path is formed between both openings 1, 4; a motor 3 provided within the housing 5; an air compression part 2 configured by joining centrifugal fans 21, each of which is formed by combining moving blades that rotate integrally with the shaft center of the motor 3, suck in air in the shaft center direction, and expel the air in the circumferential direction, and stationary blades that guide again the air expelled from the moving blades in the shaft center direction, in multiple stages along the shaft center of the motor 3; and a spray nozzle 41 provided at a discharge port 4 of the housing 5. The blower is configured to be able to suck in ambient air from a suction port 1 by activating the motor 3, generating compressed air by the air compression part 2, and spray the compressed air from the spray nozzle 41 provided at the discharge port 4. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
