Abstract
An electronic droplet delivery device with an inhalation mouthpiece that includes multiple fluid reservoirs and multiple aperture plates. Multiple fluid reservoirs allow for different fluids, such as medicines, nicotine, chemicals for marijuana, and flavorings to be separately provided from separate reservoirs into a resulting combined droplet stream inhaled by a user through the mouthpiece.
Claims28
A droplet delivery device comprising:
- a housing including an airflow exit at a mouthpiece;
- and
- a first fluid reservoir coupled to the housing in fluid communication with an electronically actuated first ejector mechanism including a first aperture plate with openings operably coupled to a first ceramic axisymmetric piezoelectric actuator;
- and
- a second fluid reservoir coupled to the housing in fluid communication with an electronically actuated second ejector mechanism including a second aperture plate with openings operably coupled to a second ceramic axisymmetric piezoelectric actuator.
