ABSTRACT:
A hand-held blow dryer includes a barrel having concentric inner and outer cylinders. The outer cylinder is slidably mounted on the inner cylinder. Each of the inner and outer cylinder comprise a plurality of holes. A deflecting mechanism is positioned at the barrel opening of the barrel, and an actuating mechanism is operationally associated with the outer cylinder and the deflecting mechanism. The hand-held blow dryer can be utilized in a first mode in which the holes of the inner and outer cylinders are not aligned to block air flow through the barrel surface and thereby direct air to the barrel opening which is opened. In a second mode, the actuating mechanism is actuated so as to slide the outer cylinder with respect to the inner cylinder to align the holes on the inner and outer cylinder and permit air flow through the aligned holes. At the same time, the deflecting mechanism is moved from a position in which the barrel opening is opened, to a position in which the barrel opening is substantially closed by the deflecting mechanism. Thus, in the second mode air is deflected by the deflecting mechanism towards the aligned holes of the inner and outer cylinder.
