The invention provides an indoor atomizer control drive circuit which comprises an automatic control circuit and an atomization drive circuit. A single chip microcomputer serves as a core in the automatic control circuit, and a running program is set in the single chip microcomputer, so that a switching quantity signal is output by the signal output end of the single chip microcomputer, and the switching quantity signal is subjected to signal conversion by a triode and then is used for driving a piezoelectric ceramic piece; the piezoelectric ceramic piece serves as a first working element in the atomization drive circuit and achieves the purpose of atomizing a water solution, and a fan motor is used for adjusting the quantity of vapor which is blown out from an atomizer; after a switching signal sent out by the piezoelectric ceramic piece in the automatic control circuit is subjected to normal vibration, the signal of the piezoelectric ceramic piece serves as a signal for conducting a fan driving triode, and therefore the fan motor can normally run. The atomization efficiency of the atomizer can be effectively guaranteed when the drive circuit is used in an indoor air purifier or air freshener.
