Patent Summary

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.
