Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1-2 , The atomizer is a piezoelectric low-frequency ultrasonic atomizer, which is mainly composed of an ultrasonic transducer 6, a horn 1 and an atomizing nozzle. The ultrasonic transducer 6 is fixedly connected to the head end of the horn 1 through the fastening screw 7, and the end of the horn is bonded to the atomizing nozzle, which includes a trapezoidal secondary atomizing mover 10, a nozzle 8 . The head end of the nozzle 8 is bonded to the end of the horn 1. The nozzle 8 is provided with a liquid inlet hole 2 and a liquid outlet hole 3. The end of the nozzle 8 is a trapezoidal nozzle groove 9, and a trapezoidal nozzle groove 9 is set at the trapezoidal nozzle groove 9. The secondary atomizing mover 10, the end of the trapezoidal secondary atomizing mover 10 is bonded to the iron core 12, the coil 5 is wo...

Abstract

The invention discloses an electromagnetically controlled low-frequency ultrasonic secondary atomization nozzle, which includes a nozzle, a liquid inlet hole is opened on the nozzle, the liquid inlet hole is connected to one end of the liquid outlet hole, the end of the nozzle is a trapezoidal nozzle groove, and the trapezoidal nozzle groove is set Trapezoidal secondary atomizing mover, the other end of the liquid outlet hole is connected to the trapezoidal nozzle groove; the iron core is bonded to the trapezoidal secondary atomizing mover, coils are wound on the iron core, and the iron core is covered by a protective cover to protect The cover is bonded to the trapezoidal secondary atomizing mover; one end of the block supports the trapezoidal secondary atomizing mover, and a sponge is inserted between the block and the trapezoidal secondary atomizing mover, and the sponge is bonded to the block, and the stopper The other end is welded to the nozzle. By adjusting the circuit to change the size of the inflow current in the coil, the magnitude of the electromagnetic force can be precisely adjusted, and the distance between the trapezoidal nozzle groove and the trapezoidal secondary atomizing mover can be precisely controlled, thereby accurately controlling the size of the generated droplets.

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 class. Ultrasonic nebulizer has a wide application prospect in the field of agricultural engineering due...
