Abstract
A venturi ejector for forcibly ejecting a slurry or solution generated in a fluid dispenser, wherein the venturi ejector includes a venturi, the venturi being in a first flow communication with the slurry or solution and developing a vacuum, the vacuum being in a second flow communication with atmospheric pressure, the second flow communication acting to cause the atmospheric pressure to exert a pressure on the slurry or solution, thereby forcing the slurry to the venturi where the slurry or solution is forcibly ejected from the venturi. A method for forcibly ejecting a slurry or solution generated in a fluid dispenser is further included.
