1. A hand-holdable, portable device which, during operation, generates an aerosolized mist of a liquid hard surface treatment composition or a liquid soft surface treatment composition, or a liquid airspace treatment composition, which aerosolized mist imparts a technical benefit to treated surfaces, or airspaces which come into contact with the said aerosolized mist, the device comprising:
a reservoir for the liquid treatment composition to be aerosolized, a mist generator assembly which comprises:
a body element formed of an flexible or elastomeric material;a base cavity present within the body element;a supply fluid conduit in fluid communication within the base cavity;an atomizing chamber within the body element;an open end of the atomizing chamber; and,a mist generator which includes a vibratable micro-perforated screen physically bonded to a piezoelectric actuator which mist generator means is mounted in a liquid, seal-tight manner within the mist generator assembly between the base cavity and the open end of the atomizing chamber the device further comprises a pump which operates to supply liquid treatment composition from the reservoir to the base cavity via the supply fluid conduit, the mist generator assembly being configured such that, during the operation of the device, liquid treatment composition is always in at least partial contact with the micro-perforated screen, the device further including means to ensure, such that during the operation of the device, a headspace is present above the liquid treatment composition within the fluid dispensing cavity, the device further comprising control means for operating the mist generator means, and optionally at least one flow directing nozzle, flow directing implement or flow directing orifice adapted to direct the flow of an aerosolized mist of the liquid treatment product generated by the mist generating means and towards a surface or into an airspace or both. |
