Title:
IMPEDANCE IDENTIFICATION METHOD FOR ULTRASONIC ATOMIZER, AND ULTRASONIC ATOMIZER
Document Type and Number:
WIPO Patent Application WO/2024/037496
Kind Code:
A1
Abstract:
An impedance identification method for an ultrasonic atomizer (100), and an ultrasonic atomizer (100). The impedance identification method is used for identifying the impedance of an ultrasonic atomization sheet (12) in an ultrasonic atomizer (100). The method comprises: acquiring a first current, wherein the first current is a current which is output from a power source (14) in an ultrasonic atomizer (100) when an ultrasonic atomization sheet (12) operates at a resonant frequency; and according to preset correspondences between currents and impedance intervals, determining an impedance interval corresponding to the first current.
