  • Sandwich Piezoelectric Ceramic Ultrasonic Atomizer
    Publication number: 20090159720
    Abstract: A sandwich piezoelectric ceramic ultrasonic atomizer has two piezoelectric ceramic plates (1) and one metal sheet (2). The metal sheet is securely clamped between the two piezoelectric ceramic plates. The two piezoelectric ceramic plates are respectively formed with a through-hole overlapping and communicated with each other, and the metal sheet completely covers the two through-holes. The present invention improves the reliability of adhesion between the metal sheet and the piezoelectric ceramic plates, thus increasing the energy conversion efficiency and extending the service life. When a bending vibration mode is adopted, the sheet metal diaphragm may be used, thereby simplifying the structure and reducing the processing cost.
