Patent ID: 7975936

Claim:
A showerhead apparatus which comprises: a first fluid passageway for conducting a stream of water, said first fluid passageway including a fitting for connecting to a water supply conduit and for receiving water into said first fluid passageway, said first fluid passageway further including an outlet for expelling fluid from within said first fluid passageway; said first fluid passageway further including a constricted section forming a venturi having a low pressure region within said first fluid passageway having a pressure that is less than ambient air pressure when water flows from said fitting through said first fluid passageway to be expelled by said outlet; a second gas passageway connected to the low pressure region of said venturi by one or more ports, said second gas passageway including one or more inlets exposed to the ambient air for receiving air into said second gas passageway, said venturi's low pressure region causing air to aspirate through said one or more inlets into said second gas passageway to enter said first fluid passageway through said ports; and an insertable and removable substantially solid scented material positioned within said second gas passageway to allow air entering said second gas passageway to pass over said scented material to create a scented gas within said second gas passageway without said scented material substantially mixing with water within said first fluid passageway as a result of said venturi aspirating air into said second gas passageway through said one or more inlets; wherein said venturi aspirates the scented gas through said ports where the scented gas mixes with water in said first fluid passageway to form a water-scented gas mixture which is expelled from said outlet.
