Abstract

An aerosol delivery device having condensing and non-condensing vaporization functionality is provided. The aerosol delivery device may comprise at least one housing, and a first element and second element contained within the at least one housing. The first and second element may be configured to activate and vaporize components of an aerosol precursor composition, and thereby form respectively a condensing vapor and non-condensing vapor. In response to a flow of air through at least a portion of the at least one housing, the condensing vapor or non-condensing vapor may be combinable with the air to form an aerosol.

First claim

What is claimed is:

1. An aerosol delivery device comprising:
at least one housing defining a reservoir for storing aerosol precursor composition;
an electromechanical device contained within the at least one housing; and
a valve positioned between the aerosol precursor composition and the electromechanical device and configured to control a flow of aerosol precursor composition from the reservoir to the electromechanical device;
wherein the electromechanical device is configured to activate in response to a flow of air through at least a portion of the at least one housing, and while activated, apply piezoelectric ultrasonic oscillations to components of the aerosol precursor composition to thereby form a vapor,
wherein the valve is further configured to be tuned by a user of the aerosol delivery device to control the flow of aerosol precursor composition.

2. The aerosol delivery device of claim 1 , wherein the at least one housing comprises a first housing and a second housing removably coupled to the first housing, wherein the first housing comprises a power source configured to supply power to the electromechanical device, and wherein the electromechanical device is contained within the second housing.

3. The aerosol delivery device of claim 2 , further comprising a third housing, the reservoir being wholly contained within the third housing, and wherein the third housing is removably coupled to the first housing and the second housing.

4. The aerosol delivery device of claim 1 , wherein the electromechanical device is contained within the reservoir.

5. The aerosol delivery device of claim 1 , wherein the at least one housing comprises a first housing and a second housing removably coupled to the first housing, wherein the first housing includes the electromechanical device and wherein the second housing includes the reservoir.

6. The aerosol delivery device of claim 1 , wherein the reservoir is refillable.

7. The aerosol delivery device of claim 6 , wherein the at least one housing further defines a port mateable with only a corresponding container of aerosol precursor composition for refilling the reservoir.

8. The aerosol delivery device of claim 1 , wherein the electromechanical device is further configured to direct at least a portion of the vapor to a vapor modification element comprising a flavor modifier.

9. The aerosol delivery device of claim 8 , wherein the flavor modifier is configured to modify the vapor by injecting a flavor composition into the vapor.

10. The aerosol delivery device of claim 9 , wherein the flavor composition is hydrophobic.

11. The aerosol delivery device of claim 10 , wherein the aerosol precursor composition is water-based.

12. The aerosol delivery device of claim 1 , wherein the electromechanical device is further configured to direct at least a portion of the vapor to a drying tube.

13. The aerosol delivery device of claim 12 , wherein the drying tube is configured to reduce a particle size of the vapor.

14. The aerosol delivery device of claim 1 , wherein the electromechanical device is further configured to direct at least a portion of the vapor to a heating element.

15. The aerosol delivery device of claim 1 , further comprising a control component configured to control an amount of electric power supplied to the electromechanical device to adjust the production of the vapor.

16. The aerosol delivery device of claim 1 , wherein the aerosol precursor composition comprises a primary aerosol precursor that is water-based.

17. An aerosol delivery device consisting of:
at least one housing defining a reservoir for storing aerosol precursor composition;
an electromechanical device contained within the at least one housing; and
a valve positioned between the aerosol precursor composition and the electromechanical device and configured to control a flow of aerosol precursor composition from the reservoir to the electromechanical device;
wherein the electromechanical device is configured to activate in response to a flow of air through at least a portion of the at least one housing, and while activated, apply piezoelectric ultrasonic oscillations to components of the aerosol precursor composition to thereby form a vapor,
wherein the valve is further configured to be tuned by a user of the aerosol delivery device to control the flow of aerosol precursor composition.
