Abstract
An electronically actuated droplet delivery device with a mouthpiece for inhaling fluid droplets includes an ejector mechanism having an electronic actuator operably coupled to an aperture plate. A fluid reservoir provided fluid to the ejector mechanism through a surface tension plate that increases contact between the fluid from the fluid reservoir and the aperture plate.
Claims30
An electronically actuated droplet delivery device comprising:
- a housing comprising a mouthpiece located at an airflow exit side of the housing;
- an unopened and prefilled fluid reservoir removably coupled with the housing;
- an electronically actuated ejector mechanism in fluid communication with the fluid reservoir and configured to generate an ejected stream of droplets;
- the ejector mechanism comprising an actuator and an aperture plate, the aperture plate having a plurality of openings formed through its thickness and the actuator operable to oscillate the aperture plate at a frequency to thereby generate the ejected stream of droplets;
- and
- a surface tension plate at a bottom of the fluid reservoir between the aperture plate and a top of the fluid reservoir, wherein the surface tension plate is combined with the fluid reservoir and ejector mechanism in a removable module having a module insertion guide and coupled with the housing.
