AEROSOL-GENERATING DEVICE AND METHOD WITH PUFF DETECTION

摘要

A method of operating an aerosol-generating device is disclosed. The aerosol-generating device comprises a power supply for supplying power to generate the aerosol, and a controller. The method comprises steps of monitoring (202) a parameter indicative of aerosol generation during operation of the aerosol-generating device, analysing (204) the monitored parameter to identify a user puff, the user puff defined by a puff start and a puff end. The monitored parameter is a power signal, and the puff is identified by comparing first and second moving averages of the power signal based on different time windows. The method may further comprise steps of analysing (205) the monitored parameter during the user puff to calculate (206) a puff volume, the puff volume being a volume of aerosol generated during the user puff, and using (207) the puff volume as a parameter for controlling operation of the device. Controlling operation of the device based on puff volume may provide an improved user experience for users who take stronger or weaker puffs than average.
