PORTABLE BLOWER
A portable blower (1) comprises: a structure (2), at least partially hollow, defining at least one conduit (3) for the transit of an air flow between a suction zone (4) and a blowing end (5), at which a blowing opening (10) of the portable blower (1) is defined; a flow generator device (6) operatively arranged inside the structure (2) which is switchable between a non-operating condition, in which no air flow is generated along the conduit (3) of the structure (2) and an operating condition, in which an air flow is generated along the conduit (3) of the structure (2) between the suction zone (4) and the blowing opening (10), wherein the flow generator device (6) defines a respective passage channel (7) for the air in transit extending along a longitudinal extension axis (X) of the flow generator device (6), optionally coinciding with a longitudinal axis of the structure (2) and/or of the conduit (3) of the portable blower (1), and is defined between an inlet section and an outlet section, wherein the passage channel (7) has in section orthogonal to the axis (X) and in the advancement direction of the air in transit towards the blowing opening (10) of the portable blower (1) between the inlet section and the outlet section, a passage section for the flow, variable in surface, which is reduced along at least one stretch of the passage channel (7).
