7. a kind of micropore atomization device control circuit and power supply state indicating means, the method is believed by microcontroller detection switch
Number, if microcontroller detects the open signal of switching signal module offer, and supply voltage is in normal scope, then micro-
Controller exports resonant frequency PWM of micropore atomization piece；Two grades of boost modules start boosting, and the voltage supply atomization after boosting is driven
Galvanic electricity road, micropore atomization piece vibration, starts spraying；Atomization signal monitoring module start to detect the signal of spray pattern and by its
It is converted into rational voltage signal and is supplied to microcontroller to be identified.
8. micropore atomization device control circuit as claimed in claim 1 and power supply state indicating means, it is characterised in that in spraying
During, if microcontroller detects power supply, load capacity deficiency will be less than threshold values, or abnormal electrical power supply will be above threshold values,
Then sprayed in mode A1：A1 sprays the T1 times, stops the T2 times, and iterative cycles point out user with this, if user has appreciated that exception
Situation simultaneously no longer receives such prompting in this task, then be input into a signal C1 from switching signal module and inform microcontroller
Device, microcontroller recover normal spraying state after receiving the signal；
If spray pattern signal will exceed in zone of reasonableness, sprayed in mode A2：A2 sprays the T3 times, stops the T4 times,
Iterative cycles, point out user with this, if user has appreciated that unusual condition and no longer receives such prompting in this task, from
Switching signal module is input into a signal C1 and informs that microcontroller, microcontroller recover normal spray form after receiving the signal
State.If spray pattern signal or power supply signal exceed threshold values, shut-off process is directly carried out, stop spraying.
9. micropore atomization device control circuit as claimed in claim 8 and power supply state indicating means, it is characterised in that using electricity
In battery-powered circuit, in normal spraying state, a signal C2 is input into from switching signal module and informs microcontroller, then with work
The mode A3 of work is sprayed, and the mode of spraying is carried out according to battery electric quantity, intermittent spray n time within the T5 times, and n is according to electricity at present
Grade belonging to cell voltage is confirmed, is input into a signal C2 from switching signal module again and informs microcontroller, then recover
Normal spraying state.
10. micropore atomization device control circuit as claimed in claim 7 and power supply state indicating means, it is characterised in that atomization is driven
NMOS, Vth≤3V of the dynamic MOS from low turn-on voltage (Vth).
