    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.

    摘要: The present disclosure provides air duct conversion bin integrated with suction and blowing, comprises an electric machinery and an air duct switching member for switching the suction mode and the blowing mode of the electric machinery; wherein the air duct switching member comprises a wind-proof sleeve which is covered on the outside of the electric machinery; the wind-proof sleeve are respectively provided with an air suction end face and an air blowing end face that can be switched on and off; the air duct switching member also includes a toggle switch. By setting the air suction end face and the wind-proof sleeve of the air blowing end face that can be switched on and off, it is not necessary to change the rotation direction of the electric machinery. At the same time, it is not necessary to set the corresponding complex circuit to reduce the production and maintenance costs.
