PURPOSE: An air sprayer is provided to oppositely contract and relax a pair of corrugated pipe members in order to repetitively spray air, thereby preventing oil from being included in the sprayed air. CONSTITUTION: An air sprayer(100) comprises a first corrugated pipe member(210), a second corrugated pipe member(220), a shaft(300), a reciprocating unit(400), a cylinder member, and a bracket. The fixed first corrugated pipe member has a first opening(212), and is contracted and relaxed so that air flows in and out of the first opening. The fixed second corrugated pipe member has a second opening, and is contracted and relaxed so that the air flows in and out of the second opening. The first and the second corrugated pipe member are mutually and oppositely contracted and relaxed. The reciprocating unit reciprocates so that the shaft axially reciprocates. |
