ABSTRACT:
An adapter for automatically dispensing any aromatic, deodorizing, cleansing, sanitizing fluid directly into the bowl of a recreational vehicle toilet as a result of operating either the bowl rinse or the bowl flush control. An apparatus adapted to toilets installed in recreational vehicles, travel trailers, an marine craft. Because it passively senses the presence of toilet inlet rinse water flow, the apparatus achieves its objective without making modifications to, and is totally independent of, the RV plumbing system. The adapter utilizes an electronic control unit which employs the electrically conductive property of water to detect the flush and the refill operations of the RV toilet. Upon detecting fresh water entering the toilet, the electronic control unit energizes an electric solenoid valve which releases a metered amount of chemical additive fluid directly into the toilet bowl. The chemical additive flow rate is fully adjustable by the user, and the chemical fluid reservoir is refillable.
