Control apparatus and method for an aromatic spray are provided to protect user's eyes by spraying after a delay time by being controlled by a micom when the power of the sprayer is turned on. A control apparatus for an aromatic spray includes a power portion(100), a power switch(200), a time selection switch(300), a crystal oscillator(400), a micom(500), buzzer and radiating diodes(700,600), N and P type transistor combinations(800,900), a motor(1000) and a gear(1100). The crystal oscillator outputs pulse signals of a basic time unit to spray in a time interval set by a user. The N and P type transistor combinations exchange the polarity of the current applied to the motor. The motor is driven when the N and P type transistors exchange the polarity of the current and apply forward and backward rotation signals. |
