Patent No. EP4340661 (titled "Aerosol Generating Device") was filed by Japan Tobacco on May 19, 2022. The application was issued on Feb 26, 2025.
Aerosol generator device that automatically starts heating when a consumable is inserted without user intervention. The device has a compartment for inserting a consumable containing an aerosol-generating substance. A cover over the compartment opening exposes it for insertion. When the cover moves to close the compartment, it sends a signal to start heating. This eliminates the need for manual heating activation and reduces wait time after inserting a consumable.
