Abstract
A hand-held electric blower includes an air-guiding pipe comprising a proximal portion or suction pipe provided with an air inlet, a distal air outlet portion or exhaust nozzle, and a fan. The blower is characterized in that the fan consists of an axial fan, and in that the suction pipe has, upstream from the axial fan, an elbow, the proximal end of which defines the air inlet and is directed downward in terms of a working position of the device, in which the operating handle of the blower is positioned above said elbow.
