Abstract

The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. In various implementations, the aerosol delivery device comprises a control device that includes an outer housing defining a cartridge receiving chamber, and further includes a power source and a control component, and a cartridge that includes a mouthpiece, a tank, a heating assembly, and a bottom cap. The mouthpiece defines an exit portal in an end thereof, and the tank is configured to contain a liquid composition therein. The cartridge is configured to be removably coupled with the receiving chamber of the control device, and the heating assembly defines a vaporization chamber and is configured to heat the liquid composition to generate an aerosol. An inlet airflow is defined by a gap between the cartridge and the control device that originates at an interface between an outer peripheral surface the mouthpiece and control device.

First claim

The invention claimed is:

1 . An aerosol delivery device comprising:
a control device that includes an outer housing defining an outer wall and having a proximal end and a distal end, the proximal end of the control device defining a receiving chamber, the control device further including a power source and a control component; and a cartridge that includes a mouthpiece, a tank, and a heating assembly, the mouthpiece having a proximal end and a distal end, the proximal end of the mouthpiece having an exit portal defined therethrough, the tank being configured to contain a liquid composition, wherein the cartridge is configured to be removably coupled with the receiving chamber of the control device, wherein the heating assembly defines a vaporization chamber and is configured to heat the liquid composition to generate an aerosol, wherein an inlet airflow is defined by a gap between the cartridge and the control device, wherein the gap originates at an interface between an outer peripheral surface of the mouthpiece and the control device, wherein the gap is established by a plurality of protuberances located on the control device, and wherein the plurality of protuberances comprises a plurality of raised elongate bosses located on an upper frame of the control device.

2 . The aerosol delivery device of claim 1 , wherein the interface is located proximate an outer peripheral surface of the mouthpiece and a top edge of the outer wall of the housing.

3 . The aerosol delivery device of claim 1 , wherein the cartridge further includes a bottom cap, and wherein an inlet channel is located in the bottom cap.

4 . The aerosol delivery device of claim 3 , wherein the inlet airflow enters the cartridge through a single inlet channel located in an approximate center of a bottom surface of the bottom cap.

5 . The aerosol delivery device of claim 3 , wherein the inlet channel located in the bottom cap has a nozzle-like shape.

6 . The aerosol delivery device of claim 3 , wherein the gap between the cartridge and the control device is established between the outer housing and the upper frame of the control device and the mouthpiece, tank, and bottom cap of the cartridge.

7 . The aerosol delivery device of claim 1 , wherein the heating assembly comprises a flat heating member and a liquid transport element, and wherein the flat heating member and the liquid transport element are installed in a curved orientation.

8 . The aerosol delivery device of claim 3 , wherein the vaporization chamber of the cartridge is defined by the bottom cap and heating assembly.

9 . The aerosol delivery device of claim 1 , wherein the tank further defines a reservoir cavity configured to hold the liquid composition.

10 . The aerosol delivery device of claim 1 , wherein an aerosol path is defined through an upper aerosol channel insert located between the tank and the exit portal of the mouthpiece.

11 . The aerosol delivery device of claim 1 , wherein the distal end of the bottom cap of the cartridge includes a pair of inserts comprising a ferromagnetic metal material.

12 . The aerosol delivery device of claim 11 , wherein the upper frame of the control device includes a pair of magnets configured to substantially align with the pair of metal inserts of the cartridge.

13 . The aerosol delivery device of claim 1 , wherein the control device includes a pressure sensor, and wherein the cartridge and the control device include a pressure path configured to signal a negative pressure to the pressure sensor.

14 . The aerosol delivery device of claim 1 , wherein an aerosol path originates at the vaporization chamber and is defined through the tank and the exit portal of the mouthpiece.

15 . The aerosol delivery device of claim 1 , wherein inlet air entering the vaporization chamber impinges on the heating member substantially perpendicularly thereto and spreads out substantially horizontally.
