Abstract
An apparatus is provided for diffusing aroma therapy oils which allows the user to pre-select a variety of aromas to be introduced at predetermined time intervals so that different moods or state of minds may be created. The apparatus includes a tray having a plurality of receptacles for various aromatic materials, and a heating means for heating a pre-selected receptacle, and thus aromatic material. The apparatus also includes a motor driven timer, that rotates the tray, so that the plurality of receptacles containing different aromatic materials are exposed to the heating means at a predetermined time period. The apparatus further includes a lid with a hole that exposes the pre-selected receptacle and aromatic material when the receptacle and aromatic material are exposed to the heating means. The aroma released from the heated aromatic material emanates into the environment through the hole. The remaining receptacles, which are out of close proximity to the heating means, are sealed to avoid the evaporation of the aromatic materials.
