Abstract

A nebulizer assembly, and more particularly, for nebulizing liquids into aerosols, includes an oscillation driver connected with an aerosol excitation device at one end thereof, a liquid delivery device adjacently disposed to the aerosol excitation device for supplying an impingement baffle provided in the aerosol excitation device with micro liquid bodies having tension liquid membranes, so that energy is completely acted upon the micro liquid membranes for excitation into aerosol particles, thereby achieving aimed excitation without causing unnecessary loads.

Claims

1. A nebulizer assembly for excitation of liquids into aerosols comprising:

a) an oscillation driver;

b) at least one plate-shaped excitation device connected to the oscillation driver and having an impingement baffle having a plurality of impingement orifices formed therein; and

c) a liquid delivery device including a plurality of capillary fibers forming micro membranes on an upper end thereof, the liquid delivery device is spaced apart from the at least one plate-shaped excitation device;

wherein the impingement baffle oscillates the micro membranes and impinges the liquids outwardly through the micro membranes, such that kinetic energy of the impingement baffle decomposes, compresses and delivers nebulized liquid particles through the plurality of impingement orifices.

2. The nebulizer assembly according to claim 1, wherein the liquid delivery device includes a liquid delivery board.

3. The nebulizer assembly according to claim 1, wherein the plurality of impingement orifices have a cone shape.

4. The nebulizer assembly according to claim 1, further comprising two reinforcement side wings, each of the two reinforcement side wings is located on one of two opposing sides of the at least one excitation device.

5. The nebulizer assembly according to claim 1, wherein the impingement baffle includes a flange rib located at a breadth thereof.

6. The nebulizer assembly according to claim 1, wherein the at least one excitation device includes two excitation devices located on opposite sides of the oscillation driver.

7. The nebulizer assembly according to claim 1, wherein the plurality of impingement orifices nave diameters to allow impurities to pass there through.
