A negative pressure suction air-water mixed jet ultrasonic oscillation high-efficiency atomization device

Abstract

The invention discloses a negative pressure suction type air-water mixed jet ultrasonic vibration efficient atomization device. The negative pressure suction type air-water mixed jet ultrasonic oscillation efficient atomization device comprises an atomization generating shell and a water-air mixed inlet shell, wherein a water inlet is formed in the lower part of the water-air mixed inlet shell; an air inlet screen is arranged on the side of the water-air mixed inlet shell; after passing through the water inlet and a water inlet channel, water flow is jetted into a water-air mixture convergent channel; negative pressure formed through jetted water draws air flow to enter the water-air mixture convergent channel; mixed water-air flow passes through a water-air mixture throat pipe and is jetted from a water-air mixture jet outlet; a self-exciting oscillation generating baffle plate is mounted on the water-air mixture throat pipe; the water-air mixture jet outlet right faces an ultrasonic oscillation seat; an ultrasonic oscillation annular cavity is arranged below the ultrasonic oscillation seat; through holes are formed in the top of the atomization generating shell; and nozzles which are uniformly and rotatably arranged are placed on the through holes. The device does not need an external air source, and has the advantages that the jet atomization effect is good, the water mist covering range is wide, the concentration of a mist field can be adjusted, the structure is simple, the processing is convenient, and the cost is low.

Description

technical field [0001] The invention relates to a negative pressure suction type air-water mixed jet ultrasonic oscillation high-efficiency atomization device, which belongs to the field of atomization devices. Background technique [0002] The living and working environment of human beings is of great significance to ensure personal safety and happiness. In today's high-tech development, some processing dust and floating objects have seriously affected people's quality of life, especially some fine dust will Cause pneumoconiosis and other physical discomfort. Ordinary pressure jet nozzles cannot meet the requirements of high-efficiency atomization. Relevant researchers have introduced high-tech means such as electromagnetic oscillation, ultrasonic wave, mechanical oscillation, and electrostatic adsorption on the basis of jet nozzles to improve the atomization effect and achieved good results. But there are some problems of high cost and relatively complex structure. [00...
