Abstract
A frequency tracking method for an ultrasonic electronic cigarette is provided. The method includes enabling start of working of an ultrasonic atomizer and selecting an oscillation frequency range of the ultrasonic atomizer as a frequency scan range according to the natural frequency characteristics of the ultrasonic atomizer. The method further includes selecting N frequency points within the frequency scan range and controlling the ultrasonic atomizer to work at the N frequency points. The method further includes finding out a maximum current value Imax and a minimum current value Imin of the ultrasonic atomizer when working at the N frequency points, and finding out a working frequency fimax corresponding to the maximum current value Imax. The method further includes controlling the ultrasonic atomizer to work at a frequency f=fimax+Δf; and detecting the working current I of the ultrasonic atomizer.
