A nebulization control system for an ultrasonic nebulizer comprising a variable pulse oscillating circuit, an ultrasonic vibrating circuit and an ultrasonic vibrator is described. The ultrasonic vibrator is caused to vibrate alternatingly between a high level which is sufficient to nebulize a fluid and a low level which is insufficient to nebulize the same. The ratio of duration of the high level to the low level and/or the amplitude of vibration at the high level is variable. This arrangement permits a precise control of nebulization quantity and assists in the production of a fine, uniform mist of fluid.

A nebulization control system for an ultrasonic nebulizer, comprising: a variable pulse oscillating circuit, an ultrasonic vibrating circuit, the vibration amplitude of which depends upon the output of said variable pulse oscillating circuit, and an ultrasonic vibrator which is energized by the output of said ultrasonic vibrating circuit, wherein said ultrasonic vibrator is caused to vibrate in alternation between a predetermined high amplitude level which is sufficient to nebulize fluid and a predetermined low amplitude level, greater than zero, which is at or near the maximum amplitude at which nebulization will not take place.
