The present disclosure relates to the technical field of electronic atomization, and discloses a method for measuring a number of puffs and an aerosol generating device. In the method for measuring a number of puffs, based on a relationship between a coil voltage and a temperature at resonance, the coil voltage at each moment is collected in real time, a real-time temperature of an induction heater assembly is determined according to each coil voltage, and the number of puffs of the aerosol generating device is measured according to the real-time temperature. Then, the aerosol generating device is replenished with energy according to the number of puffs, an amount of aerosols can be guaranteed to be adjusted to maintain in a vapeable state, and tastes and puff experience can be improved. In addition, by determining the number of puffs of the aerosol generating device based on the coil voltage, dependence on a measuring chip is eliminated, and the problem of insufficient or excessive heat absorption of an aerosol generating substrate caused by a fault of the measuring chip is avoided. In addition, hardware cost can be further effectively reduced.
