摘要： A backpack power tool has drive motor and blower mounted on a backpack frame. The bottom plate of the backpack frame has a passage for working air sucked in by the blower. Ribs on the bottom side of the bottom plate have end faces forming a contact surface for leaves aspirated in blower operation against the bottom plate. The bottom plate has intake openings positioned between the end faces of the ribs in the contact surface and fluidically connected to the passage. Working air is sucked in through the intake openings and the passage. The bottom plate has an intake surface that is the sum of surfaces of all intake openings and of all end faces of ribs with a width of less than 10 mm positioned between the intake openings. The intake surface amounts to at least 50% of the surface of the bottom side of the bottom plate.

摘要： A handheld blower apparatus includes a handle, a blower tube, a blower unit arranged in the tube, and has an intake opening and a discharge opening. The blower unit has a blower wheel rotationally driveable about a rotational axis aligned in the direction of an air flow flowing out from the wheel during operation. The wheel is driven by an electric motor supplied with energy by a battery. A handle opening extends between the handle and tube. A central plane intersects the handle and battery and contains the rotational axis. A compact, ergonomic arrangement is achieved when the battery and the handle are arranged on opposite sides of the tube and the top side of the tube, when viewed in the direction perpendicular to the central plane, has an indentation extending over at least 50% of the length, measured parallel to the rotational axis, of the handle opening.
