ABSTRACT:
A multiple dilution ratio aspirator sprayer adapted to be connected to a hose for mixing a liquid with pressurized water from the hose and providing a spray of the mixture comprises a container for housing the liquid to be mixed with the water; a mixing head having a nozzle at one end thereof and a garden hose attachment device at the other end thereof; a mixing chamber within the mixing head; a hose for communicating the liquid from the container to the mixing head; a disk having a plurality of apertures therein rotatably mounted in the mixing head to control flow from the container to the mixing chamber; a flow tube communicates liquid in the container to the inlet to mixing chamber through a selected aperture in the disk so that the liquid is diluted with pressurized water at a dilution ratio determined by the size of the aperture aligned with the tube and the mixing chamber; and a cleaning orifice is positioned circumferentially from the mixing chamber so that each of the plurality of apertures may be selectively aligned therewith for cleaning.
