Abstract

The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides devices configured for vaporization of an aerosol precursor composition through radiant heating. The radiant heat source may be a laser diode or further element suitable for providing electromagnetic radiation, and heating may be carried out within a radiation-trapping chamber. In some embodiments, an interior of such chamber may be configured as a black body or as a white body.

Claims (11)

1. An aerosol delivery device comprising: an outer shell; a radiation-trapping chamber positioned within the outer shell and comprising a chamber wall, wherein an interior of the chamber wall is configured as a black body or a white body; a radiation source configured to provide radiation within the radiation-trapping chamber; and wherein the radiation-trapping chamber is spherical.

2. An aerosol delivery device comprising:

an outer shell;

a radiation-trapping chamber with a chamber wall, the radiation-trapping chamber being spherical;

a heater configured for vaporizing an aerosol precursor composition, the heater comprising a laser diode and being positioned within the radiation-trapping chamber; and

a wick configured to deliver the aerosol precursor composition from a reservoir to be in a vaporizing arrangement with the heater.

3. An aerosol delivery device comprising: an outer shell; a radiation-trapping chamber with a chamber wall, the radiation-trapping chamber being spherical; and a heater configured for vaporizing an aerosol precursor composition, the heater comprising a laser diode and being positioned within the radiation-trapping chamber; and a wick configured to deliver the aerosol precursor composition from a reservoir to be in a vaporizing arrangement with the heater, wherein the wick passes through at least one aperture in the chamber wall of the radiation-trapping chamber such that a first section of the wick is positioned exterior to the radiation-trapping chamber and a second section of the wick is positioned interior to the radiation-trapping chamber.

4. An aerosol delivery device comprising: an outer shell; a radiation-trapping chamber with a chamber wall, the radiation-trapping chamber being spherical; and a heater configured for vaporizing an aerosol precursor composition, the heater comprising a laser diode and being positioned within the radiation-trapping chamber; and a wick configured to deliver the aerosol precursor composition from a reservoir to be in a vaporizing arrangement with the heater; wherein an interior of the chamber wall of the radiation-trapping chamber is configured to one or more of absorb, emit, and reflect radiation from the radiation source.

5. An aerosol delivery device comprising: an outer shell; a radiation-trapping chamber with a chamber wall, the radiation-trapping chamber being spherical; and a heater configured for vaporizing an aerosol precursor composition, the heater comprising a laser diode and being positioned within the radiation-trapping chamber; and a wick configured to deliver the aerosol precursor composition from a reservoir to be in a vaporizing arrangement with the heater; wherein an interior of the chamber wall is configured as a black body.

6. An aerosol delivery device comprising: an outer shell; a radiation-trapping chamber with a chamber wall, the radiation-trapping chamber being spherical; and a heater configured for vaporizing an aerosol precursor composition, the heater comprising a laser diode and being positioned within the radiation-trapping chamber; and a wick configured to deliver the aerosol precursor composition from a reservoir to be in a vaporizing arrangement with the heater; wherein an interior of the chamber wall is configured as a white body.

7. An atomizer for an aerosol delivery device, the atomizer comprising: a radiation-trapping chamber formed of a chamber wall, wherein an interior of the chamber wall is configured as a black body or a white body; a radiation source positioned within the radiation-trapping chamber; and a wick, at least a portion of which is positioned within the radiation-trapping chamber so as to be in a vaporizing arrangement with the heater; and wherein the radiation-trapping chamber is spherical.
