Abstract: A blower (1) comprises a blast fan (20) provided within a casing (10), a driving unit (30) for rotationally driving the blast fan (20), a dust-proof cover (60) provided so as to cover an air intake (11) of the casing (10) and a drive stop mechanism (70) for stopping the driving unit (30). The drive stop mechanism (70) comprises a depressing lever (72) that depresses a pressure sensor (71) when it is pressed by a projection (65b) of the dust-proof cover (60) that is inserted into an attachment hole (12) of the casing (10) and a control section (73) for stopping the driving unit (30) when the pressure acting on the pressure sensor (71) from the depressing lever (72) decreases. This structure allows safety of the blower to be improved when the dust-proof cover (60) is removed from the air intake (11) and the air intake (11) is exposed to the outside because the rotation of the blast fan (20) automatically stops.

Abstract: A blower (1) has a blow fan (20) provided in a casing (10), a drive device (30) for rotating the blow fan (20), and a blow duct (40) for discharging airflow outside, which the air flow is generated by the rotating blow fan (20), wherein a dust proof cover (60) is attached to a suction inlet (11) formed in the casing (10), and openings (64a, 65a) for drawing outside air are formed in the left and right side faces (64, 65) of the dust proof cover (60), and the left and right side faces (64, 65) are inclined inward in the right-and-left width direction as they extend downward. According to such a configuration, the openings (64a, 65a) of the dust proof cover (60) are prevented from being clogged with dust such as dead leaves to prevent overheating of the drive device (30).
