Abstract

An aerosol generating system includes, a body defining a cavity having a cavity opening, an aerosol-forming substrate disposed in the cavity, a heating element disposed proximate to the cavity opening, and a controller configured to detect contact of the aerosol-forming substrate with the heating element.

Claims (19)

1. An aerosol generating system comprising:

a body defining a cavity having a cavity opening;

an aerosol-forming substrate disposed in the cavity;

a heating element disposed proximate to the cavity opening;

a controller configured to detect contact of the aerosol-forming substrate with the heating element; and

a mechanical advancement mechanism configured to advance the aerosol-forming substrate towards the heating element.

2. The aerosol generating system according to claim 1 , wherein the controller detects a resistance of the heating element.

3. The aerosol generating system according to claim 1 , wherein the aerosol-forming substrate is a gel or viscous liquid that volatizes when heated by the heating element.

4. The aerosol generating system according to claim 1 , wherein the heating element is a mesh layer disposed across the cavity.

5. The aerosol generating system according to claim 1 , further comprising a rigid base disposed within the cavity and being movable only in one direction toward the heating element.

6. The aerosol generating system according to claim 5 , further comprising an advancement mechanism configured to advance or move the rigid base toward the heating element.

7. The aerosol generating system according to claim 6 , wherein the advancement element comprises a spiral element disposed on the body and rotational movement of a portion of the body moves the rigid base toward the heating element.

8. The aerosol generating system according to claim 7 , wherein the rigid base or body comprises a stop element configured to allow rotation of the rotational portion of the body in only one direction.

9. The aerosol generating system according to claim 6 , wherein the body forms a cartridge that is received in an aerosol-generating device and the advancement element forms a portion of the cartridge and the heating element forms a portion of the aerosol-generating device.

10. The aerosol generating system according to claim 6 , wherein the body forms a cartridge that is received in an aerosol-generating device and the advancement element forms a portion of the aerosol-generating device and the heating element forms a portion of the cartridge.

11. The aerosol generating system according to claim 1 , further comprising a visual indicator configured to activate when the controller detects a resistance threshold value of the heating element, and the visual indicator comprises an indicator light or a graphical user interface or both an indicator light and a graphical user interface.

12. The aerosol generating system according to claim 1 , further comprising an actuator configured to move the aerosol-forming substrate toward the heating element when the controller detects a resistance threshold value of the heating element.

13. The aerosol generating system according to claim 1 , wherein the aerosol-forming substrates comprises nicotine.

14. The aerosol generating system according to claim 1 , further comprising a power source operably coupled to the controller.
