Method and system for controlling oscillation of ultrasonic atomizing sheet

Abstract

The invention discloses a vibration control method and control system of an ultrasonic atomizing sheet. The control method includes: A, the ultrasonic atomizing sheet starts to work; B, sweeps the frequency of the ultrasonic atomizing sheet and Detect its working current, store the sweep frequency value and working current detection value; C, filter out the maximum current value I 0 and the corresponding frequency value f 0 ; D, determine the resonant frequency range as [f min , f max ], the safe current range is [I min , I max ]; f min =f 0 +Δf,f max =f 0 +m·Δf, Δf is the minimum frequency value of the chip in the working circuit, m is a set positive integer, I min is f max Corresponding working current detection value, I max is f min The corresponding operating current detection value; E, with the driving frequency f n Drive the ultrasonic atomizing sheet to work, f n The initial value of f 0 +Δf. The invention controls the working current by controlling the working frequency of the ultrasonic atomizing sheet, has good frequency and current matching, avoids burning components, has high working efficiency, good atomizing effect, large amount of smoke, and good user experience.

Description

technical field [0001] The invention particularly relates to a method and a control system for controlling the oscillation of an ultrasonic atomizing sheet. Background technique [0002] At present, in ultrasonic electronic cigarettes, the ultrasonic atomizing sheet is driven to work at a fixed frequency. However, in fact, the resonant frequency of the ultrasonic atomizing sheet will change during the working process. Therefore, driving the ultrasonic atomizing sheet at a fixed frequency will cause the current in the circuit to change continuously, which has the following defects: [0003] First, when the current in the circuit is relatively high, it is easy to burn out the components in the circuit and increase the cost of use. [0004] Second, the working current and the resonant frequency basically do not match, the atomization effect of the ultrasonic atomizing sheet is very poor, and the user experience is poor. Contents of the invention [0005] The object of the p...
