Abstract
Provided is a vacuum blower, when used as a vacuum for sucking work, capable of increasing air flow with a larger volume of air sucked from a suction port and increasing the initial velocity (sucking rate) of sucked objects near the suction port, and when used as a blower for blowing work, capable of delivering rectilinearly directed wind from the blowing port and quickly switching between sucking work and blowing work. By sliding an inner pipe disposed inside a pipe relative to the pipe, opposite end portions of the inner pipe come into close contact with opposite end portions (turn portions) of a nozzle facing the opposite end portions of the inner pipe, such that one ejection port is closed and the other ejection port is opened to allow pressurized wind generated by a blower fan to be ejected along the inside of the inner pipe to switch between sucking state and blowing state.
