Abstract:
1. A device for exposing air to an aromatic substance, said device comprising: a housing having an upper part and a lower part, the upper part being embodied as a lid that includes air inlet means and air outlet means; a motor disposed under the lid and protected by a motor cover, having an output shaft situated axially, and a motor activation means controlled by depression of a micro-switch; an impeller means for inducting air into the device through an air inlet hole(s) in the lid, through an attached air intake housing structure providing air-flow guidance means, said impeller also providing a means for pushing the inducted air through hollow free space in the device housing toward an outlet hole(s) in the lid; a conically shaped hollow draw tube disposed onto an underside of the impeller for fluid pumping means, is situated axially and rotates cooperatively with impeller, the apposing end comprising a small hole which is immersed in a liquid solution, a means for a 360 degree radial discharge of said fluid through wide and narrow outlet channels located upwardly and axially of the draw tube as draw tube is rotated; and a lower base part being embodied as a reservoir tank that serves for holding an aromatic liquid solution, with a remaining free space to be formed in the tank above the surface of the liquid therein allowing an air flow means through the device housing, providing a mixing chamber area; an outward pointing flange comprising the lip of the reservoir tank providing a micro-switch engagement means.
