Abstract
An electronic droplet delivery device includes a housing including a mouthpiece located at an airflow exit side of the housing, a fluid reservoir, an aperture plate having a plurality of openings that receives fluid from the reservoir, an electronic actuator that oscillates the aperture plate to generate an ejected stream of droplets, and an ejector closure that opens and closes to help seal and prevent evaporation from the aperture plate when the droplet delivery device is not being used.
Claims27
An electronically actuated droplet delivery device comprising:
- a housing including a mouthpiece located at an airflow exit side of the housing;
- a fluid reservoir disposed within or in fluid communication with the housing;
- an electronically actuated aperture plate having a plurality of openings formed through its thickness wherein the aperture plate is in fluid communication with the fluid reservoir;
- an electronic actuator operably coupled to oscillate the aperture plate at a frequency that generates an ejected stream of droplets;
- and
- an ejector closure coupled to the housing that opens and closes relative to the aperture plate.
