US 8,095,997 B2 · Modular cartridge based liquid dispenser system for toilets and bidets

Abstract

A modular cartridge based liquid dispensing system for automatically dispensing a metered amount of liquid(s) into a toilet water tank and/or bowl. This unique programmable system mounts onto a standard water tank, and is shaped to match the tank so that it blends well with the existing toilet design for aesthetics. It is designed to dispense one or a plurality of solution types, allowing any desired solution to be dispensed, such as cleaning solutions and deodorants. It uses replaceable liquid cartridges that can be refillable or disposable, and can also use fixed tanks. This invention can also utilize all of its components in a low-rise cabinet chassis that allows the entire system to be mounted inside the water tank where it is completely hidden from view. The system also has provisions for an optional automatic toilet flushing device and can also be used to dispense its liquids to a bidet apparatus.
