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) and/or the conduit (3) 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 end (5) and/or the blowing opening (10); a protection grille (7) arranged along the conduit (3) of the structure (2) of the portable blower (1) between the flow generator device (6) and the blowing opening (10), in which the protection grille (7) has a substantially reticular structure (8) in which one or more elements (8a, 8b) of the reticular structure (8) have an aerodynamic profile (9), optionally a wing profile, defined between a rounded attachment edge (9a) facing the flow generator device (6) and an outlet edge (9c), and in which the aerodynamic profile (9) has a maximum thickness in an intermediate zone (9b) interposed between the attachment edge (9a) and the outlet edge (9c), in which one or more elements (8a, 8b) of the reticular structure (8) have at least one among an upper, or extrados, surface and a lower, or intrados, surface of convex shape.
