Abstract

An aerosol delivery device having a detachable power source is provided. A control body may be coupleable with a cartridge to form an aerosol delivery device. The cartridge may contain an aerosol precursor composition and be equipped with a heating element configured to activate and vaporize components of the aerosol precursor composition. The control body may comprise a housing and a power source detachably coupled to an outer surface of the housing. A control component may be contained within the housing and configured to operate in an active mode in which the control body is coupled with the cartridge. The control component in the active mode may be configured to direct power from the power source to the heating element to activate and vaporize components of the aerosol precursor composition.

First claim

What is claimed is:

1. A control body coupled or coupleable with a cartridge that contains an aerosol precursor composition, the control body being coupled or coupleable with the cartridge to form an aerosol delivery device configured to activate and vaporize components of the aerosol precursor composition, the control body comprising:
a housing;
a primary power source within the housing;
a secondary power source detachably coupled to an outer surface of the housing; and
a microprocessor contained within the housing and configured to:
operate in an active mode in which the control body is coupled with the cartridge, the microprocessor in the active mode being configured to power the aerosol delivery device to activate and vaporize components of the aerosol precursor composition, and
switchably direct power from the primary power source and the secondary power source;

wherein the secondary power source is rechargeable and coupleable with at least a charging component configured to charge the secondary power source, in at least one instance with the secondary power source detached from the outer surface of the housing, and in at least one instance with the secondary power source coupled to the outer surface of the housing; and
wherein the microprocessor being configured to switchably direct power from the primary power source and the secondary power source includes being configured to direct power from the primary power source, and switch to the secondary power source only after the primary power source has discharged by at least a threshold amount.

2. The control body of claim 1 , wherein the secondary power source is or includes one or more lithium-ion batteries or capacitors, and
wherein the microprocessor being configured to direct power from the secondary power source includes being configured to direct power from the one or more lithium-ion batteries or capacitors.

3. The control body of claim 1 , wherein the secondary power source being coupleable with the charging component includes being inductively coupleable with the charging component configured to wirelessly charge the secondary power source.

4. The control body of claim 1 , wherein the secondary power source being coupleable with the charging component includes being wirelessly coupleable with a radio frequency (RF) transmitter configured to wirelessly charge the secondary power source.

5. The control body of claim 1 , wherein the secondary power source being coupleable with the charging component includes being coupleable with a charging stand configured to charge the secondary power source with the secondary power source coupled to the outer surface of the housing.

6. The control body of claim 5 further comprising a universal serial bus (USB) port coupled to the housing, the secondary power source being detachably, electrically coupleable to the USB port,
wherein the secondary power source being coupleable with the charging stand includes the USB port being coupleable with a USB charging interface of the charging stand.

7. The control body of claim 5 , wherein the secondary power source being coupleable with the charging stand includes the primary power source and secondary power source being coupleable with the charging stand configured to simultaneously charge the primary power source and secondary power source.

8. A method of controlling an aerosol delivery device including a control body with a primary power source within the housing coupled with a cartridge that contains an aerosol precursor composition, the aerosol delivery device configured to activate and vaporize components of the aerosol precursor composition, the method comprising:
detachably coupling a secondary power source to an outer surface of the control body; and
powering the aerosol delivery device to activate and vaporize components of the aerosol precursor composition, wherein the control body is configured to switchably direct power from the primary power source and the secondary power source,
wherein the secondary power source is rechargeable and the method further comprises coupling the secondary power source with at least a charging component configured to charge the secondary power source, in at least one instance with the secondary power source detached from the outer surface of the housing, and in at least one instance with the secondary power source coupled to the outer surface of the housing; and
wherein switchably directing power from the primary power source and the secondary power source includes directing power from the primary power source, and switching to the secondary power source only after the primary power source has discharged by at least a threshold amount.

9. The method of claim 8 , wherein the secondary power source is or includes one or more lithium-ion batteries or capacitors, and directing power from the secondary power source includes directing power from the one-or-more lithium-ion batteries or capacitors.

10. The method of claim 8 , wherein coupling the secondary power source with the charging component includes inductively coupling the secondary power source with the charging component configured to wirelessly charge the secondary power source.

11. The method of claim 8 , wherein coupling the secondary power source with the charging component includes wirelessly coupling the secondary power source with a radio frequency (RF) transmitter configured to wirelessly charge the secondary power source.

12. The method of claim 8 , wherein coupling the secondary power source with the charging component includes coupling the secondary power source with a charging stand configured to charge the secondary power source with the secondary power source coupled to the outer surface of the control body.

13. The method of claim 12 , wherein a universal serial bus (USB) port is coupled to the control body, and the secondary power source is detachably, electrically coupleable to the USB port,
wherein coupling the secondary power source with the charging stand includes coupling the USB port with a USB charging interface of the charging stand.

14. The method of claim 12 , wherein coupling the secondary power source with the charging stand includes coupling the primary power source and secondary power source with the charging stand configured to simultaneously charge the primary power source and secondary power source.
