<p>A dispensing apparatus for dispensing essential oils comprising an absorbent element (40) and an air impeller (41 ) to generate the flow of air across the absorbent element. The apparatus includes an oil supply unit (1 ) having a mounting arrangement to receive the neck of an inverted bottle (30). The mounting arrangement defines a liquid flow-path (10) extending from the recess to a dispensing point, from which the oil passes to the absorbent pad, and an air-flow path (16) extending to the recess. A solenoid (20) control valve may be actuated to open the air-flow path for a predetermined time to permit air to flow through the path and into the bottle thus allowing a predetermined quantity, for example one drop, of liquid to be dispensed from the bottle on to the absorbent element.</p> |
