Abstract
A low-frequency ultrasonic atomizing device includes a piezoelectric vibrator, a horn, a secondary atomizing chamber, a gas-liquid valve end cover, a Laval-type valve core, a stepped valve core, and a gas-liquid valve body. The piezoelectric vibrator is glued onto the horn, and the gas-liquid valve end cap is connected to the gas-liquid valve body by a thread, while both the stepped valve core and the Laval-type valve core are installed within a cylindrical cavity of the valve body, an end of the Laval-type valve core being sleeved at an end of the stepped valve core. The horn and the secondary atomizing chamber, the secondary atomizing chamber and the gas-liquid valve end cover are connected by a double-head stud and a nut. The device achieves multi-stage atomization of droplets, which increases the atomization quantity of a spray device, the droplets being small, and also achieves long distance spraying.
