Patent Images
1. An aerosol delivery device, comprising:
- a reservoir at least partially filled with an aerosol precursor composition;
a bubble jet head in fluid communication with the reservoir, the bubble jet head being configured to dispense the aerosol precursor composition from the reservoir; and
an atomizer configured to heat the aerosol precursor composition dispensed by the bubble jet head to produce an aerosol, the bubble jet head and the atomizer being fixedly coupled to one another,wherein the reservoir comprises a proximal end and an opposing distal end, and a reservoir substrate defining a porous medium with wicking channels configured to direct the aerosol precursor composition to the bubble jet head coupled to the distal end of the reservoir, andwherein the porous medium is exposed at the distal end of the reservoir to direct the aerosol precursor composition directly to the bubble jet head.

Abstract
The present disclosure relates to aerosol delivery devices. The aerosol delivery devices include mechanisms configured to deliver an aerosol precursor composition from a reservoir to an atomizer including a vaporization heating element to produce a vapor. For example, a bubble jet head may be configured to dispense the aerosol precursor composition to the atomizer. The bubble jet head may be fixedly coupled to the atomizer. The bubble jet head may include a precursor inlet, an ejection heating element, and a precursor nozzle. The atomizer may include a vaporization heating element.
