METHOD AND APPARATUS FOR DETACHABLE STRING TRIMMER HEAD FOR BLOWER/TRIMMER COMBINATION

摘要

A combination blower assembly and string trimmer (10) whereby the string trimmer head (52) is easily detachable without the use of any tools. The device includes a blower assembly (12) that further includes an upper (14) and lower (16) housing mated together to form a volute-shaped cavity where an impeller (18) with airfoil-shaped blades reside. The detachable string trimmer head (52) is located under the lower housing (16) of the blower assembly (12) and is easily attached or removed from the blower assembly (12) by a simple push and turn motion. The blower assembly further includes an air inlet (20) and air inlet cover (22). When the air inlet cover (22) is rotated to a position where the air inlet (20) is open the blower assembly (12) is operable and the string trimmer (52) is inoperable. Furthermore, when the air inlet cover (22) is rotated to a position where the air inlet (20) is closed the blower assembly (12) is inoperable and the string trimmer (52) is operable.
