Abstract

The invention discloses a natural focusing type ultrasonic atomization nozzle. The technical problems, such as large volume, invalid liquid splashing at a center hole, large air consumption, small maximal liquid flow, short spraying distance, of a natural scattering type atomization nozzle in the prior art are solved. According to the technical scheme, the natural focusing type ultrasonic atomization nozzle comprises an ultrasonic atomization energy converter, an air channel, a liquid nozzle and an outer shell, wherein the ultrasonic atomization energy converter is arranged in the outer shell; the liquid nozzle is fixedly arranged under the outer shell through a damping supporting mechanism; the air channel is arranged in the middle of the ultrasonic atomization energy converter; the ultrasonic atomization energy converter comprises a piezoelectric vibration pile and an ultrasonic amplitude transformer; the piezoelectric vibration pile is arranged in the outer shell; the ultrasonic amplitude transformer is located in the liquid nozzle; an atomization head end face is arranged on the bottom end face of the ultrasonic amplitude transformer; a nozzle liquid outlet of the liquid nozzle is concentrically surrounding the atomization head end face; a nozzle liquid inlet of the liquid nozzle is arranged on the upper part of the liquid nozzle. The natural focusing type ultrasonic atomization nozzle has the advantage that high-precise high-efficient ultrasonic atomization spraying can be realized.

Description

technical field [0001] The invention relates to an ultrasonic atomization spraying equipment, in particular to a natural focus type ultrasonic atomization spray head for precision spraying, spray printing and inkjet painting. Background technique [0002] Atomization spraying is to use external energy to disperse liquid into tiny particles, and then spray it onto the corresponding surface. The spraying technologies widely used in the market are pressure atomization and pneumatic atomization spraying. Its main disadvantages are that due to the high working pressure and the fast spraying speed of the atomized particles, the splash is serious, the utilization rate of the material is low, the pollution is serious, and the cleaning is difficult. Ultrasonic atomization is a flexible atomization spraying technology developed for this reason. It mainly uses ultrasonic vibration to atomize the liquid, and then uses low-pressure gas to form an atomized beam. Due to the low pressure...
