Atomizers belong to the general field of spray or atomization devices. They consist of a piezoelectric ceramic and a metal film. The metal film is welded to the edge of the piezoelectric ceramic. A microporous area is located in the center of the metal film, with a margin around the edges. The silver-printed area on one side of the piezoelectric ceramic extends in the thickness direction of the piezoelectric ceramic, while the silver-printed area on the other side of the piezoelectric ceramic leaves a margin. This facilitates a stronger weld between the metal film and the ceramic, effectively preventing the atomized liquid from contacting the silver-printed electrodes after deposition and causing short circuits. This utility model offers excellent atomization performance and significantly increases service life. Also known as a sprayer, this device uses compressed air or other combustion-supporting gases to atomize the test solution into uniform, fine mist droplets, which are then sprayed stably and efficiently into the flame during flame atomic emission and absorption spectroscopy analysis. Pneumatic atomizers are available in right-angle and concentric circular types; ultrasonic atomizers are also available. Requirements for an atomizer include stable spray, fine droplets, a large mist volume introduced into the flame per unit time, and high atomization efficiency.
