Title
(EN) ELECTROSTATIC SPRAYING
(FR) PULVERISATION ELECTROSTATIQUE
Abstract
(EN)
An electrostatic spraying device is disclosed which is suitable for, but not limited to, dispensing an electrostatically sprayable substance for nasal or oral inhalation. Electrical charge is imparted to the spray particles by applying a high voltage to the substance prior to break up into a spray. In one embodiment, the device includes a nozzle portion for registry with the nasal or oral cavity and defines a passageway through which, in use, air can be drawn by inhalation on the part of the user. The substance to be sprayed passes into the passageway so that, with the assistance of user-induced air flow through the passageway, the resulting spray passes into the oral or nasal cavity.
(FR)
L'invention concerne un dispositif de pulvérisation électrostatique qui permet, entre autres, de distribuer une substance pouvant être pulvérisée de manière électrostatique, en vue d'une inhalation orale ou nasale. On confère une charge électrique aux particules pulvérisées en appliquant une tension élevée à la substance, avant qu'elle ne se rompe pour former un brouillard de pulvérisation. Dans un mode de réalisation, le dispositif comprend une partie formant buse adaptée à la cavité nasale ou bucale et définit un passage dans lequel, en service, l'air peut être aspiré par inhalation de l'utilisateur. La substance à pulvériser passe dans le passage, de sorte que sous l'influence de l'écoulement d'air induit par l'utilisateur dans le passage, le brouillard ainsi crée soit envoyé dans la cavité orale ou nasale.
