A shower head attachment has a liquid detergent reservoir and facilitates a “soap,”“rinse,”and “off”cycle. The attachment has a body provided with a rotary valve having a transverse port. The port is alined, selectively, with a first or second longitudinal inclined passageway formed in the body forwardly of the valve. A third passageway of critical internal diameter communicates the first passageway with an opening formed in a depending neck on the body and acts as an aspirating passageway. A sleeve is secured within the opening and carries a depending feed tube. The feed tube extends into a reservoir or bottle of liquid detergent that is removably mounted on the depending neck of the body, externally of the sleeve. The sleeve has a valve seat above the feed tube, and a ball check valve is seated on the valve seat. The valve carries an external handle; and the ends of the handle carry depending cables, the ends of which are provided with respective tabs. A pin on the body is received in an arcuate slot in the handle to limit the rotary movement of the handle and valve. The liquid detergent is biodegradable and cooperates with the aspirating passageway to prevent clogging. It is critical that the liquid detergent has the proper viscosity relative to the internal diameter of the aspirating passageway so that the detergent is aspirated out of the bottle and into the shower head attachment at the desired rate.

A shower head attachment, comprising a body having a generally longitudinal axis and including a rearward portion having means for attachment to the shower head, the body further including a substantially closed forward portion having first and second passageways formed therein, a nozzle carried on the body forwardly thereof and in communication with the first and second passageways, the body having a transverse bore formed therein intermediately of its forward and rearward portions, the bore being transverse to a vertical plane encompassing the longitudinal axis of the body, a valve comprising a substantially cylindrical member rotatably mounted in the transverse bore and having at least three positions including first, second and third positions, respectively, an external handle disposed laterally of the body and mounted to the valve for rotation in unison, stop means between the handle and the body for limiting the rotary movement of the handle and the valve mounted thereto, first and second cables carried by the respective ends of the handle, a tab carried on the end of each cable, the tabs having respective geometric plan outlines which are different from one another, the valve having a transverse port formed therein, the body having a depending neck portion provided with an opening formed therein, the body further having a third aspirating passageway formed therein communicating the first passageway with the opening in the neck portion, the third aspirating passageway being inclined to the first passageway and intersecting the first passageway near the beginning thereof substantially close to the rotatable valve, a bottle of liquid detergent removably mounted on the neck portion and depending therefrom, and a feed tube means depending into the bottle of liquid detergent and communicating with the opening in the neck portion; whereby in the first position of the valve, the transverse port in the valve communicates the rearward portion of the body with the first passageway for flow of water therethrough and to the nozzle, whereby liquid detergent is aspirated through the feed tube means and via the third passageway into the first passageway, thereby constituting a “soap”position of the valve; and whereby in the second position of the valve, the transverse port in the valve communicates the rearward portion of the body with the second passageway for flow of water therethrough to the nozzle without aspiration of liquid detergent, thereby constituting a “rinse”position of the valve; and whereby in the third position of the valve between its first and second positions, the valve blocks water flow into either the first or second passageways, thereby constituting an “off”position of the valve.
