Abstract
An aerosol generator includes a first body having a first end including an exit opening, and an oppositely positioned second end. An open channel second body is substantially positioned inside the first body and extends from the first end to the second end of the first body. An exit opening of the second body is positioned adjacent to the exit opening of the first end of the first body. An insert, which holds material to be aerosolized, is at least partially positioned inside the second body. An inlet opening receives compressed air into the first body. The compressed air flows towards the exit opening of the first end of the first body. The air flow creates a region of low pressure at the exit opening of the second body. The region of low pressure pulls the material out from the second body and aerosolizes the material. The aerosol generator is particularly effective in generating aerosols from small amounts of solid and liquid materials with minimal losses of material.
