METHOD AND APPARATUS FOR CLEANING A HEATING ELEMENT OF AEROSOL GENERATING DEVICE
First Claim
1. An aerosol-generating device, comprising:
- a heating element coupled to a controller,wherein the controller is programmed to actuate the heating element through a first thermal cycle in which a temperature of the heating element is raised to a first temperature to form an aerosol from an aerosol-forming substrate disposed in proximity to the heating element,wherein the controller is programmed to actuate the heating element through a second thermal cycle in which the temperature of the heating element is raised to a second temperature, higher than the first temperature, to thermally liberate organic material adhered to or deposited on the heating element, andwherein the controller is programmed to actuate the heating element through the second thermal cycle automatically when the aerosol-forming substrate is removed from contact with the heating element.

Abstract
An aerosol-generating device is provided, including a heating element coupled to a controller, wherein the controller is programmed to actuate the heating element through: a first thermal cycle in which a temperature of the heating element is raised to a first temperature to form an aerosol from an aerosol-forming substrate disposed in proximity to the heating element; a second thermal cycle in which the temperature of the heating element is raised to a second temperature, higher than the first temperature, to thermally liberate organic material adhered to or deposited on the heating element; and the second thermal cycle automatically when the aerosol-forming substrate is removed from contact with the heating element. A method of controlling an aerosol-generating device having a reusable heating element is also provided.

13. A method of controlling an aerosol-generating device having a reusable heating element, comprising:
-
raising a temperature of the heating element to a first temperature to heat an aerosol-forming substrate in contact with the heating element sufficiently for an aerosol to be formed; and automatically raising the temperature of the heating element to a second temperature, higher than the first temperature, when the aerosol-forming substrate is removed from contact with the heating element to thermally liberate organic materials adhered to or deposited on the heating element. - View Dependent Claims (15, 17, 18)

14. A method of using an aerosol-generating device having a reusable heating element, comprising:
-
bringing the heating element into contact with an aerosol-forming substrate; raising a temperature of the heating element to a first temperature to heat the aerosol-forming substrate sufficiently for an aerosol to be formed; removing the heating element from contact with the aerosol-forming substrate; and automatically raising the temperature of the heating element to a second temperature, higher than the first temperature, when the aerosol-forming substrate is removed from contact with the heating element to thermally liberate organic materials adhered to or deposited on the heating element. - View Dependent Claims (16, 19, 20)
