Ultrasonic spraying device for atomizing viscous liquid and suspension liquid

Abstract

An ultrasonic spraying device for atomizing viscous liquid and suspension liquid comprises a rear seat, a transducer, a transducer rear end, a piezoelectric vibrator group, an electrode soldering lug, a transducer front end, a shell, an electrical port, a liquid inlet port and an air inlet port. When the ultrasonic spraying device works, liquid enters the ultrasonic spraying device from the liquid inlet port, flows to an atomizing end face through a straight-through hole in the energy transducer and is atomized. By the aid of an amplitude-change pole and acoustic surface wave atomizing principle, the vibration amplitude of ultrasonic waves emitted by the ultrasonic transducer is increased by the ultrasonic amplitude-change pole, the liquid with high viscosity or the solid particle suspension liquid can be atomized, the efficiency of the spraying device is improved, and more than 1L / h atomizing quantity can be provided for pure water atomizing 1W electric power. The ultrasonic resonance frequency of the ultrasonic spraying device ranges from 20kHz to 300kHz.

Description

Technical field [0001] The invention relates to a liquid spraying device, in particular to an ultrasonic spraying device for atomizing a suspension with high viscosity or containing tiny solid particles, and belongs to the field of ultrasonic atomization. Background technique [0002] Liquid atomization is the process of dispersing and tearing liquid by applying mechanical energy or vaporizing it into fine particles by applying heat energy. The conversion efficiency of heating atomization devices is generally low, and it is not suitable for use in some medical or chemical fields where the atomized liquid cannot be heated. [0003] Since the 1970s, ultrasonic atomization, as a new type of liquid atomization technology, has been widely used in various fields such as medical treatment, civil use, industry, and scientific research. Ultrasonic atomization is the use of high-frequency oscillations emitted by ultrasonic transducers to tear the liquid on the surface of the transduc...

AI Technical Summary

Problems solved by technology

However, due to the metal fatigue of the microporous metal sheet, the micropores are easy to block, etc., the stability and life of the ultrasonic atomization device are low, and because it cannot load a large power, the atomization amount of the atomization device is generally Smaller, no more than 100ml / h

And although the principle of leverage is used, the vibration amplitude of the metal sheet is still limited, and the micropores are too small and easy to be blocked, making this kind of atomizer the same as the traditional high-frequency piezoelectric ceramic atomizer, which cannot atomize the viscosity higher liquid

[0005] Since the existing ultrasonic atomization devices cannot atomize liquids with high viscosity or solid impurities, and the atomization volume is low, ultrasonic atomization can only be used in the fields of air humidification, aromatherapy and beauty.
