摘要:
In an ultrasonic wave nebulizer having a piezoelectric vibrator (1) at the bottom of a water container for exciting ultrasonic vibration of water on the water surface to convert water to mist, a flat plate (16) having a center aperture (15) is provided above the vibrator (1) with a spacing (Z) between the plate (16) and the vibrator (1), so that the aperture (15) is positioned above the center of the vibrator (1). The plate (16) has no further apertures except the center aperture (15). The diameter (D) of the aperture (15) is smaller than the diameter (A) of the vibrator (1). The presence of the aperture (15) above the vibrator (1) improves the performance of the nebulizer, and increases the generation of mist.
