Title
(EN) ELECTROSTATIC VAPOR-AEROSOL GENERATOR
(FR) GENERATEUR DE VAPEURS ET/OU D'AEROSOLS ELECTROSTATIQUE
Abstract
(EN)
The controlled generation of vapors and/or aerosols from liquids is accomplished by applying a regulated, DC voltage to a wick-like, porous emitter or generator assembly (16) which is supplied with the desired liquid (17) to be vaporized. An electrostatic charge is applied to the liquid by means of an electrode (5) positioned in contact with the wick assembly (8) and connected to the DC power supply. The wick assembly includes a porous, capillary material (10), such as braided fibers, through which the liquid passes to exposed, vapor emitting fiber tips (10c). The environment in a room, enclosed space of any kind, or a building may be aromatically conditioned and/or have its quality modified and enhanced by using a selected liquid conditioning substance such as an aromatic oil, deodorant, disinfectant, fumigant, fungicide, insecticide, or bactericide.
(FR)
On génère de façon contrôlée des vapeurs et/ou des aérosols à partir de liquides en appliquant une tension en courant continu réglée à un ensemble générateur ou émetteur poreux de type mèche (16) alimenté par le liquide désiré (17) destiné à être vaporisé. Une charge électrostatique est appliquée au liquide au moyen d'une électrode (5) placée en contact avec l'ensemble mèche (8) et connectée à l'alimentation en puissance en courant continu. L'ensemble mèche comprend un matériau capillaire poreux (10) tel que des fibres tressées, à travers lequel le liquide passe vers des pointes de fibres mises à nu et émettant de la vapeur (10c). L'environnement d'une pièce, d'un espace fermé quelconque ou d'un bâtiment peut être traité aromatiquement et/ou être modifié ou amélioré en qualité grâce à l'utilisation d'une substance contenant un liquide choisie, telle qu'une huile aromatique, un déodorant, un désinfectant, un fumigateur, un fongicide, un insecticide ou un bactéricide.
