Abstract
Abstract 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 which is supplied with the desired liquid to be vaporized. An electrostatic charge is applied to the liquid by means of an electrode positioned in contact with the wick assembly and connected to the DC power supply. The wick assembly includes a porous, capillary material, such as braided fibers, through which the liquid passes to exposed, vapor-emitting fiber tips. The environment in a room, or enclosed space of any kind, 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.
