A plumbing fixture including, but not limited to, an aspirating type shower head 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. When not in use this opening may plugged. When one is about to take a shower and a pleasant scent is desired, a small scent cartridge is selected, bent to break the seal, thereby activating the scent material to migrate on the surrounding wick. 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. The scent molecules then enter the venturi and mix with the high velocity water stream. The mixture of water and scented air then exit the showerhead in a spray pattern and fill the shower compartment with the desired fragrance. After use the cartridge is disposable. In other variations a carousel of long life scents may be connected in fluid communication to the air chamber at the venturi. |
