Abstract
A piezoceramic based atomizer for atomizing high viscosity liquid is provided. The atomizer comprises a storing tank as a reservoir for storing the liquid, a receiving tank connecting to the storing tank, a piezoceramic based nozzle for forming micro-droplets of the liquid, and an external ultrasonic oscillation circuit. The nozzle comprises a liquid absorbing medium with at least one sunk area at one end for pumping and delivering the liquid, a holder for holding the absorbing medium, a micro-perforated membrane whose one side is attached on the side of the liquid absorbing medium having the sunk area, and an annular piezoceramic adhered to the other side of the membrane. The nozzle is configured such that the sunk area can balance the feeding rate and atomization rate of the liquid as well as hold the back pressure underneath the micro-perforated membrane, facilitating forming micro-droplets of the high viscosity liquid continuously.
