Abstract

The invention discloses a low-frequency ultrasonic secondary atomizing spraying head controlled in an electromagnetic mode. The low-frequency ultrasonic secondary atomizing spraying head comprises a nozzle. A liquid inlet hole is formed in the nozzle and communicated with one end of a liquid outlet hole. A trapezoidal nozzle groove is formed in the tail end of the nozzle and provided with a trapezoidal secondary atomizing moving body. The other end of the liquid outlet hole is communicated with the trapezoidal nozzle groove. An iron core and the trapezoidal atomizing moving body are bonded together. A coil winds around the iron core which is covered with a protecting cover. The protecting cover and the trapezoidal secondary atomizing moving body are bonded. One end of a stop block supports the trapezoidal secondary atomizing moving body. A sponge is stuffed between the stop block and the trapezoidal secondary atomizing moving body and bonded to the stop block. The other end of the stop block is welded to the nozzle. Currents flowing into the coil are changed by adjusting a circuit, electromagnetic force can be adjusted accurately, the distance between the trapezoidal nozzle groove and the trapezoidal secondary atomizing moving body is controlled accurately, and therefore the size of generated mist drops can be accurately controlled.

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...
