AEROSOL DELIVERY DEVICE AND METHOD OF OPERATING THE AEROSOL DELIVERY DEVICE |
摘要 |
The invention relates to an aerosol delivery device (A) comprising an aerosol generator for generating an aerosol in the aerosol delivery device with a membrane (1) and a vibrator (7) which is configured to vibrate a fluid and to aerosolise the fluid by the membrane (1). The aerosol delivery device (A) further comprises a fluid reservoir (2) for receiving the fluid (3) to be aerosolised, the fluid reservoir (2) being arranged in fluid communication with the membrane (1), a controller (10) which is configured to sequentially operate the vibrator (7) at a plurality of different vibration frequencies, a sensor (13) which is configured to detect at least one electrical parameter of the vibrator (7) for each of the plurality of different vibration frequencies, 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 dependence of the detected values of the at least one electrical parameter on the vibration frequency. Further, the invention relates to a method of operating said aerosol delivery device (A). |
