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.

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 heating element to produce a vapor. A pressure controller may control dispensing of the aerosol precursor composition from the reservoir based on a pressure differential between a first pressure within the reservoir and a second pressure proximate the atomizer. The first pressure within the reservoir may be substantially equal to atmospheric pressure. Alternatively, the first pressure within the reservoir may be greater than atmospheric pressure.

US Classification:

392387, 392394

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 heating element to produce a vapor. An actuator may displace a rod to dispense the aerosol precursor composition to the atomizer. Thereby, the rod may move a piston in a pump housing to dispense the aerosol precursor composition. The atomizer may define a chamber in which the heating element is positioned and at which the aerosol precursor composition is vaporized.
