Abstract

The invention provides a piezoelectric-pneumatic composite ultrasonic atomization sprayer. Combination of a broken line type gas ultrasonic oscillation resonant cavity and a piezoelectric ultrasonic transducer is adopted, multi-stage atomization of liquid is achieved, then super-fine fog drops are generated, and the piezoelectric-pneumatic composite ultrasonic atomization sprayer can be used in the fields like plant protection, atomization cultivation and ultrasonic spraying.

Description

technical field [0001] The invention relates to the field of atomization cultivation, in particular to a piezoelectric-pneumatic composite atomization nozzle technology. Background technique [0002] Piezoelectric ultrasonic atomizer has a wide range of application prospects in the field of agricultural engineering due to its advantages such as small and uniform droplet size. Piezoelectric ultrasonic atomization destroys the liquid water structure through the high-frequency resonance of the ceramic atomizing sheet to produce ultrasonic atomization. The droplets produced by the piezoelectric ultrasonic atomizing nozzle are extremely fine, but the amount of atomization is very small. The pneumatic atomizing nozzle has a large amount of atomization, but the droplets are relatively thick. How to generate extremely fine droplets with a large amount of atomization is an urgent problem in the fields of atomization cultivation, plant protection and spraying. Contents of the inve...
