Abstract
There is provided an ultrasonic atomizer having a start/stop switch and when the switch is turned on (ST1) an oscillation frequency generation unit and an air feeding motor are operated (ST2), an air volume dial is checked and a decision is made as to whether the current mode is a continuous mode or a timer mode (ST3, ST7). If it is the continuous mode a state of operation is displayed by dynamically moving a segment on a display and periodically ringing a buzzer to notify the user accordingly (ST4, ST5). The start/stop switch is turned off, an oscillation unit is stopped and an oscillator is turned off (ST10, ST11), and the air feeding motor is also stopped (ST12). If this state is provided in the continuous mode then an inactive state is indicated by static characters “00” (ST14). This ensures that the user can determine whether the ultrasonic atomizer in the continuous mode currently has the active state or the inactive state.
