Abstract

An aerosol impingement baffle, and more particularly, an aerosol impingement baffle employed in ultrasonic nebulizers, wherein the impingement orifices thereof are formed by disposing line-shaped impingement grooves at the inner breadth of the impingement baffle, thereby increasing the differentiation probabilities of liquid particles and avoiding congestions thereof.

Claims

1. An aerosol impingement baffle for an ultrasonic nebulizer comprising:

a) an impingement baffle having a plurality of impingement grooves, each of the plurality of impingement grooves being a wave shape; and

b) a piezoelectric ceramic connected directly to the impingement baffle.

2. The aerosol impingement baffle according to claim 1, wherein each of the plurality of impingement grooves has a width in a range between 100 microns and 120 microns.

3. The aerosol impingement baffle according to claim 1, wherein the piezoelectric ceramic is connected directly to the impingement baffle by metal welding.
