EP3666316A1 — Aerosol delivery device and method of operating the aerosol delivery device

USPTO Abstract

The invention relates to an aerosol delivery device (A) comprising an aerosol generator for generating an aerosol in the aerosol delivery device (A). The aerosol generator comprises a membrane (1) and a vibrator (7) which is configured to vibrate a fluid (3) and to aerosolise the fluid (3) by the membrane (1). The aerosol delivery device (A) further comprises a fluid reservoir (2) for receiving the fluid (3) to be aerosolised, wherein the fluid reservoir (2) is arranged in fluid communication with the membrane (1). Moreover, the aerosol delivery device (A) comprises a controller (10) which is configured to operate the vibrator (7) so as to vibrate the fluid (3), a temperature sensor (13) which is configured to detect a temperature of the vibrator (7) and/or the membrane (1), and a detector (13a) which is configured to detect the presence of fluid (3) in contact with the membrane (1) and/or in the fluid reservoir (2) on the basis of the temperature of the vibrator (7) and/or the membrane (1) detected by the temperature sensor (13). Further, the invention relates to a method of operating such an aerosol delivery device (A).
