Spray ejector device and methods of use

摘要

An ejector device (100) for ejecting droplets of fluid onto a surface includes an ejector mechanism (108) attached to a fluid reservoir (102) through a fluid loading plate (104) that is configured to pierce the reservoir and channel the fluid to a rear surface of the ejector mechanism (108) by capillary action. The ejector mechanism (108) may have a centro-symmetric configuration with a lead free piezo actuator and may be covered by an auto-closing cover.
