Low-frequency ultrasonic secondary atomizing sprayer with adjustable spray angle

Abstract

The invention discloses a low-frequency ultrasonic secondary atomizing sprayer with an adjustable spray angle of an ultrasonic atomizer. A nozzle is provided with a liquid inlet hole, the liquid inlet hole is communicated with one end of a liquid outlet hole, the tail end of the nozzle is a trapezoid nozzle groove, a trapezoid secondary atomizing active cell is arranged at the trapezoid nozzle groove, and the other end of the liquid outlet hole is communicated with the trapezoid nozzle groove; an adjusting screw penetrates the trapezoid secondary atomizing active cell and is connected with the secondary atomizing active cell and the nozzle by virtue of screw threads; the adjusting screw is provided with a balance spring, one end of the balance spring is supported on the tail end face of the trapezoid secondary atomizing active cell, and the other end of the balance spring is supported on the tip of the adjusting screw; and a distance between the trapezoid nozzle groove and the trapezoid secondary atomizing active cell is 0-1mm. The adjustable trapezoid secondary atomizing active cell is adopted, thus the regulating range of fog drop size is increased, the nozzle can regulate the fog drop size at any position by virtue of the balance spring, and a mounting angle is flexible.

Description

technical field [0001] The invention relates to an ultrasonic atomizer used in the field of industry and agriculture, in particular to an atomizing nozzle structure of the ultrasonic atomizer. Background technique [0002] Ultrasonic nebulizer has a wide range of application prospects in the field of industry and agriculture due to its advantages of small and uniform droplet size and easy control of atomization volume. In the industrial field, ultrasonic nebulizers have been widely used in air humidification, drug atomization treatment, semiconductor etching, salt spray test of electronic products, and spectral analysis. Use ultrasonic nebulizer to humidify the air, the effect is good and the response is quick. In the petrochemical industry, the atomization performance of ultrasonic burners has obvious advantages over other types of burners. The size of the droplets is small and the uniformity of the droplets is better. In the field of agriculture, the application of ultra...

AI Technical Summary

Problems solved by technology

This ultrasonic atomizing nozzle has a large amount of atomization, high reliability, controllable droplet size and low cost. Its disadvantages are: 1. The distance between the ball and the nozzle can only be adjusted by changing the material of the steel ball.

1. Since the sphere is completely suspended, the nozzle can only spray vertically upwards
