Abstract

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices may include a control body, an atomizer body including an atomizer, and a cartridge including a reservoir configured to contain an aerosol precursor composition. The control body may be configured to releasably engage the atomizer body and the atomizer body may be configured to releasably engage the cartridge. The atomizer may be configured to receive an electrical current from the control body and the aerosol precursor composition from the cartridge to produce an aerosol.

First claim

The invention claimed is:

1. An aerosol delivery device, comprising:
a control body;
an atomizer body comprising an atomizer; and
a cartridge comprising a reservoir configured to contain an aerosol precursor composition,
wherein the control body is configured to releasably engage the atomizer body, and the atomizer body is configured to releasably engage the cartridge,
wherein the atomizer is configured to receive an electrical current from the control body and the aerosol precursor composition from the cartridge to produce an aerosol,
wherein the control body, the atomizer body, and the cartridge comprise separate components, and wherein the atomizer comprises a flow director, and the flow director includes a central inlet air channel, and one or more radial inlet air holes configured such that air that enters through the central inlet air channel is directed through the one or more radial inlet air holes.

2. The aerosol delivery device of claim 1 , wherein the atomizer further comprises a liquid transport element.

3. The aerosol delivery device of claim 2 , wherein the liquid transport element comprises a porous monolith.

4. The aerosol delivery device of claim 2 , wherein the atomizer further comprises a heating element comprising a wire at least partially imbedded in the liquid transport element.

5. The aerosol delivery device of claim 4 , wherein the liquid transport element defines a tube, and the atomizer further comprises a capillary rod extending through the liquid transport element and configured to direct the aerosol precursor composition therethrough.

6. The aerosol delivery system of claim 1 , wherein the control body further comprises a sensor, the sensor being configured to detect a user draw on the cartridge.

7. The aerosol delivery system of claim 1 , wherein the atomizer further comprises an outer body, a terminal base, and a liquid transport element comprising a porous monolith, and wherein an atomizer chamber is created by the flow director, the terminal base, and an inside surface of the liquid transport element.

8. The aerosol delivery system of claim 2 , wherein the flow director further includes one or more inlet liquid flow chambers configured to deliver the aerosol precursor composition to the liquid transport element.

9. The aerosol delivery system of claim 8 , wherein the outer body includes one or more vapor apertures, and the flow director further includes one or more radial inlet vapor holes, one or more radial vapor channels, and one or more vertical vapor holes, configured such that the aerosol is directed through the one or more radial inlet vapor holes, the one or more radial vapor channels, the one or more vertical vapor holes of the flow director, and the one or more vapor apertures of the outer body and into one or more vapor channels of the cartridge.

10. The aerosol delivery device of claim 1 , wherein the flow director has a “T” shape comprising an upper flange and a lower cylinder.

11. The aerosol delivery device of claim 1 , wherein the cartridge comprises one or more air flow apertures extending from the atomizer body to a mouthpiece, the air flow apertures being configured to direct the aerosol therethrough.
