Low-frequency ultrasonic triple atomization nozzle

Abstract

The invention discloses a low-frequency ultrasonic triple atomization nozzle which comprises an ultrasonic transducer, an amplitude transformer, a flange, a liquid inlet hole, a liquid outlet hole, an eccentric ball, a pressing block, a limit spring and support frame, wherein the upper end surface of the ultrasonic transducer is bonded together with the lower end surface of the amplitude transformer; the conical upper end surface of the amplitude transformer is connected with the flange into a whole; the upper end surface of the flange is welded together with the support frame; the plane on which the support frame is located passes through the axis of the low-frequency ultrasonic triple atomization nozzle; one end of the limit spring is welded at the upper part on the inner side of the support frame; the other end of the limit spring is welded together with the pressing block; the pressing block, the length direction of the limit spring and the axis of the low-frequency ultrasonic triple atomization nozzle are collinear; and the eccentric ball is pressed in a nozzle groove by the pressing block. The low-frequency ultrasonic triple atomization nozzle performs tertiary atomization of a nutrient solution on the basis of secondary atomization, breaks through the bottleneck that a low-frequency ultrasonic atomization nozzle can hardly generate superfine droplets and enables the low-frequency ultrasonic atomization nozzle to achieve a better development prospect in the field of aeroponic culture.

Description

technical field [0001] The invention relates to an ultrasonic atomizer used in the field of atomized cultivation, in particular to an atomization nozzle structure of the ultrasonic atomizer. Background technique [0002] Ultrasonic atomization is to use the principle of electronic ultra-high frequency oscillation to pass an oscillating current of a certain frequency on the ultrasonic generator to generate a high-frequency electric energy signal, which is converted into ultrasonic mechanical vibration (ie ultrasonic wave) through a transducer; Medium propagation, surface tension waves are formed at the gas-liquid interface, and the force of liquid molecules is destroyed due to ultrasonic cavitation, and droplets are formed from the surface of the liquid, thereby realizing atomization of the liquid, and the diameter of the droplets of ultrasonic atomization reaches microns Level, water mist contains a lot of negative ions, which can increase air humidity and freshen the air, a...

Problems solved by technology

This ultrasonic atomization nozzle has large atomization volume and high reliability, but its disadvantage is that the energy of the sound field is not fully utilized. Although the droplets produced by it are smaller than those produced by one atomization, the average droplets are still suitable for atomization cultivation. Too big
