Abstract

Claims (35)

1. A method of manufacturing a device for generating aerosol, comprising

a. embedding a susceptor into a consumable-containing unit;

b. placing the consumable-containing unit and the susceptor into an encasement, wherein the encasement has a first end and a second end opposite the first end, wherein the encasement comprises an opening;

c. placing the encasement into a filter; and

d. placing the filter containing the encasement into a housing.

2. The method of claim 1 , further comprising applying a coating onto the opening.

3. The method of claim 1 , wherein the consumable-containing unit is pressed into a pellet to minimize oxygen within the pellet.

4. The method of claim 3 , wherein the consumable-containing unit is mixed with an additive to minimize oxygen within the pellet.

5. The method of claim 4 , further comprising placing a plurality of encasements stacked inside the filter.

6. The method of claim 5 , wherein the encasements are separated from each other by a fold created in one or more ends of the encasement.

7. The method of claim 6 , further comprising providing a heating element to heat the susceptor and a self-resonant oscillator for controlling the heating element.

8. The method of claim 7 , wherein the heating element is configured to heat the susceptor to a temperature of 400 degrees C. or higher.

9. A device for generating aerosol, comprising:

a. a consumable-containing unit;

b. a susceptor embedded within the consumable-containing unit;

c. a heating element configured to at least partially surround the consumable-containing unit and configured to heat the susceptor to a temperature of 400 degrees C. or higher;

d. a controller to control the heating element;

e. a case to contain the consumable-containing unit, the susceptor, the heating element, and the controller; and

f. a self-resonant oscillator for controlling the heating element wherein the self-resonant oscillator comprises a capacitor operatively connected to the heating element, wherein the heating element comprises a plurality of coiled wires each coiled wire operatively connected to the controller for activation independent of the other coiled wires.

10. The device of claim 9 , wherein the consumable-containing unit is pressed into a pellet to minimize oxygen within the pellet.

11. The device of claim 10 , wherein the consumable-containing unit and the susceptor are enclosed in an encasement, wherein the encasement comprises openings, and the openings are covered with a coating.

12. The device of claim 11 , wherein the heating element is configured to move relative to the consumable-containing unit.

13. The device of claim 12 , wherein the susceptor is a multi-pronged susceptor.

14. A device for generating aerosol, comprising:

a. a consumable-containing unit;

b. a susceptor embedded within the consumable-containing unit;

c. a heating element configured to at least partially surround the consumable-containing unit and configured to heat the susceptor to a temperature of 400 degrees C. or higher;

d. a controller to control the heating element; and

e. a case to contain the consumable-containing unit, the susceptor, the heating element, and the controller, wherein the heating element is moveable, wherein the consumable-containing unit is an elongated member defining a first longitudinal axis, and wherein the heating element is configured to move axially along the first longitudinal axis.

15. The device of claim 14 , wherein the consumable-containing unit comprises a cylindrical magnet at one end of the consumable-containing unit, the cylindrical magnet defining a second longitudinal axis, wherein the heating element is a cylindrical coil wrapped around the consumable-containing unit, the cylindrical coil defining a third longitudinal axis, wherein the cylindrical magnet and the heating element are configured to maintain collinear alignment of the second longitudinal axis with the third longitudinal axis.

16. The device of claim 14 , wherein the susceptor is a multi-pronged susceptor.

17. The device of claim 16 , wherein the heating element is configured to rotate about the consumable-containing unit.

18. The device of claim 17 , wherein the multi-pronged susceptor comprises a plurality of prongs parallel to each other and embedded within the consumable-containing unit.

19. The device of claim 18 , wherein the consumable-containing unit is an elongated member defining a first longitudinal axis, wherein the heating element is a coil wrapped around the consumable-containing unit to form a cylinder defining a second longitudinal axis, and wherein the heating element is configured to rotate about the consumable-containing unit in an eccentric path such that the second longitudinal axis aligns collinearly with each of the prongs of the multi-pronged susceptor at some point during the rotational movement of the heating element about the consumable-containing unit.

20. The device of claim 16 , wherein the consumable-containing unit is an elongated member defining a longitudinal axis, and wherein the heating element is configured to move radially relative to the longitudinal axis.
