Abstract

A foamed cleaning liquid dispensing system includes a cleaner cartridge (234), a flow control device (202), and an aerator (204). The cleaner cartridge includes a supply of cleaning agent (200). The flow control device is configured to receive a flow of the cleaning agent (208) from the cartridge and a flow of a primary cleaning liquid component (210). The flow control device combines the flows of cleaning agent and primary cleaning liquid component and produces an output flow of cleaning liquid (214) at an output (216). The aerator includes an inlet (324) fluidically coupled to the output of the flow control device, an outlet (334), and a gas inlet (342). The aerator is configured to receive the output flow of cleaning liquid at the inlet, inject gas into the output flow of cleaning liquid through the gas inlet, and produce an output flow of foamed cleaning liquid (218) through the outlet.
