Piezoelectric fluid atomizer apparatuses and methods
Piezo aerosol and ultrasonic atomizer apparatuses are disclosed. In some embodiments, a piezo aerosol apparatus may comprise a piezo component defining an opening bonded to a metal plate defining a mist reservoir. The mist reservoir may define a plurality of apertures (or holes) orientated substantially perpendicular, and the opening of the piezo component may be located above the mist reservoir. The piezo aerosol apparatus generally defines a non-symmetric compound, while the ultrasonic atomizer comprises a piezo component and metal plate of substantially the same diameter in length. Other embodiments are also claimed and disclosed.
1. A piezo apparatus comprising:
(a) a piezo component having a top and a bottom surface and defining an opening;
(b) a metal plate having a top surface and bottom surface and defining a mist reservoir, the mist reservoir defining a plurality of holes orientated substantially perpendicular to the top surface of the metal plate;
(c) a floating washer; and
(d) a floating washer holder;
wherein the top surface of the metal plate being adhered to the bottom surface of the piezo component, wherein the opening of the piezo component is located above the mist reservoir; and the floating washer and the floating washer holder being configured to support the metal plate while allowing the piezo component and the metal plate the freedom to effectively vibrate.
2. The apparatus of claim 1 , the metal plate having a first thickness and the mist reservoir having a second thickness, wherein the second thickness is less than the first thickness.
3. The apparatus of claim 1 , wherein the piezo component and the metal plate are disk shaped.
4. The apparatus of claim 1 , wherein the metal plate is stainless steel.
5. The apparatus of claim 3 , the metal plate having a first diameter and the piezo component having a second diameter, wherein the first diameter is larger than or approximately equal to the second diameter.
6. The apparatus of claim 1 , wherein the piezo component comprises an electrode to receive a voltage.
7. The apparatus of claim 1 , wherein the metal plate comprises an electrode to receive a voltage.
8. The apparatus of claim 1 , wherein the mist reservoir is adapted to receive a wick.
9. The apparatus of claim 1 , further comprising a cap, wherein the floating washer defines a vertical wall to enclose an aerosol component; the floating washer holder is adapted to hold the floating washer and the aerosol component; and the cap is adapted to engage the floating washer holder and springedly coupled to the floating washer and to conceal the aerosol component.
10. The apparatus of claim 9 , wherein the floating washer has a general dome shape adapted to limit upward movement of the aerosol component.
11. The apparatus of claim 9 , wherein the floating washer defines a depression for receiving a spring.
12. The apparatus of claim 9 , further comprising a conical spring adapted to springedly couple the floating washer and the cap.
13. The apparatus of claim 9 , wherein the mist reservoir is adapted to receive a wick and the aerosol component is adapted to contact the wick in response to receiving a voltage.
14. The apparatus of claim 9 , wherein the floating washer holder has an “L” shaped cross section to support the vertical wall of the floating washer and an outer peripheral edge of the aerosol component.
15. The apparatus of claim 9 , wherein the mist reservoir defines a plurality of holes in fluid communication with the opening defined by the piezo component such that fluid particles may pass through the aerosol component.
