There is described a battery driven atomizer in which an alternating voltage is applied to a piezoelectric actuation element (10) to cause it to expand and contract and vibrate an atomizing orifice plate. The alternating voltage is controlled to produce a high amplitude vibration during a first portion of a drive period, to initiate atomization, and thereafter to produce a lower amplitude vibration to sustain atomization during the remainder of the drive period. The frequency of the alternating voltage is swept repeatedly during each drive period.
La présente invention a pour objet un atomiseur à piles dans lequel une tension alternative est appliquée à un élément de commande piézo-électrique (10) pour provoquer la dilatation, la contraction et la vibration d'une plaque d'orifice de pulvérisation. La tension alternative est contrôlée pour produire une vibration à forte amplitude pendant une première partie de la commande de l'atomiseur pour soutenir la pulvérisation pendant le reste de la période de commande. La fréquence de la tension alternative effectue plusieurs balayages répétés pendant chaque période de commande.
