Abstract

The invention provides an intelligent piezoelectric single liquid drop generator and a method thereof. The intelligent piezoelectric single liquid drop generator comprises a one-way flow valve, a piezoelectric spray head and a controller; the one-way flow valve comprises a valve body; the valve body is gradually expanded; the piezoelectric spray head comprises a cavity, a nozzle and piezoelectricceramics; one end of the cavity is detachably connected with the wide end of the valve body; the nozzle is formed in the other end of the cavity; N groups of piezoelectric ceramics are arranged on thecavity; each group of piezoelectric ceramics is provided with M pairs of piezoelectric ceramics; M is greater than or equal to 2; the M pairs of piezoelectric ceramics are uniformly distributed alongthe circumference of the cavity; and the controller is connected with drivers of the piezoelectric ceramics correspondingly. By controlling the working frequency of multiple piezoelectric ceramics arranged on the spray head, the amplitude can be controlled and then the vibration amplitude of a housing of the cavity of the spray head is controlled, the vacuum degree caused by piezoelectric vibration at the nozzle is adjusted, the pressure in the cavity of the spray head is changed by multiple times of expansion and contraction so that multi-level control is realized, liquid is subjected to multiple-stage division, the volume of liquid drops is controlled, and the generation speed of the liquid drops is capable of being controlled.

Description

technical field [0001] The invention belongs to the research field of atomization cultivation, and in particular relates to an intelligent piezoelectric single droplet generator and a method thereof. Background technique [0002] 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, and how to generate droplets of corresponding size and control the speed of droplet production according to actual needs is an urgent problem to be solved in the fields of atomization cultivation, plant protection and spraying. Contents of the invention [0003]...
