Abstract: Disclosed herein is a device that is able to produce a flow of ionized air of alternatively positive and negative sign so that it be possible to eliminate static electricity from the objects towards which the said flow is directed, in an efficient and continuous fashion; the disclosure refers in particular to a hand gripped or to a hood type hair drying apparatus.The main characteristic lies in the fact that it comprises, in combination: a ducted electric fan connected to an electric circuit; at least one electric generator for alternatively producing electric charges of opposite sign; at least one metal electrode connected electrically to the electric generator, supported inside the said duct and placed along the path followed by the flow of air leaving the device, generated by the operation of the said electric fan; and means for actuating the electric generator during the operation of the electric fan.

Abstract: Disclosed herein is an apparatus for neutralizing electrostatic charges and for removing dust from various objects, comprising a trough shaped member fixed to a handle inside which a piezoelectric transducer is housed, the latter being connected electrically to an electrode located inside the trough shaped member and actuated by a pushbutton that protrudes from the handle.
