Aerosol-Generating Device Automatically Performing Heating Operation

Patent No. EP3869982 (titled "Aerosol-Generating Device Automatically Performing Heating Operation") was filed by KT & G on Dec 10, 2020. The application was issued on Feb 19, 2025.

Patent Summary

Aerosol-generating device that automatically prevents excessive heating of the device when a cigarette is inserted, while maintaining continuous heating when the device is in a normal operating state. The device detects temperature changes in multiple sensors positioned around the device, including a thermistor adjacent to the battery and a temperature/humidity sensor at the battery's lower surface. When a cigarette is inserted, the device monitors temperature changes in these sensors to determine if the device is overheated. If it detects overheating, the device suspends the heating operation. When the device is in a normal operating state, it continuously heats the inserted cigarette. This approach eliminates the need for manual intervention to prevent overheating, while maintaining continuous heating when the device is operating normally.
