ABSTRACT:
A plumbing fixture including an aspirating type showerhead operates to add a selected scent to the spray water. The showerhead utilizes a venturi assembly where the water supply passes through a venturi. A negative pressure is created at the high velocity water jet stream point, near the narrow area of the venturi. A number of small openings in the venturi, to a surrounding air chamber, allow air from the chamber, to be drawn into the venturi. The air chamber has inlet openings for the aspiration of room air. At a portion of these inlet openings is a quick connect port to receive a scented cartridge. The scent cartridge is then inserted into the quick connect port of the showerhead. Room air is then drawn through and over the scent cartridge where the high velocity air picks up scent molecules from the scented wick within the cartridge.
