Resistance R11 sampling voltage is converged to triode Q2 ON operation in pole.After triode Q2 ON operation, from the pole C of triode Q2
Voltage from the pole E output after, respectively through resistance R12 drive work light D1, D2, through resistance R13 driving triode Q4 be connected
Control blower M work is gone in work.
The tie point for the pole C that 2 feet of main control chip U1 are connected to triode Q4 through the cathode of blower M feeds back the voltage to come
Reasonable value voltage is obtained after resistance R14, R15 carrys out auxiliary function inspection water function.
The excessive low water level protection working principle of atomizing piece:
When machine use water level less on atomizing piece Y1 or it is anhydrous when, the interruption of the 3 feet output of main control chip U1
The pole B that voltage carrys out driving triode Q1 through the sampling voltage of capacitor C2, resistance R2, R3 and R8 works.Due to the spy of atomizing piece Y1
Property (operating power generated when having no water or little water is smaller), so produced by the tie point of resistance R4 and inductance coil L2
6 foot feedback voltage electric currents it is smaller, cannot make main control chip U1 work normally, to can reach excessive low water level protection function.
