SummaryThe present invention provides a device and a method for producing atomized ozonated water by ultrasound and is related to the field of environmental management. The device for producing atomized ozonated water by ultrasound comprises an ozone generator, an ultrasonic atomizer, and a first pipeline. The ozone generator and the ultrasonic atomizer are connected by the first pipeline. In particular, the ozone generator is used to receive oxygen from an oxygen generation system and convert oxygen into ozone, and then feed the ozone into the ultrasonic atomizer through the first pipeline. The ultrasonic atomizer is used to either atomize water by ultrasonic technology before it is mixed with the ozone from the ozone generator to form atomized ozonated water, or atomize ozonated water, which is formed by dissolving ozone in water, to form atomized ozonated water by ultrasonic technology. The present invention can provide a cleansing element for air purification, dissolution of chemical gases and assurance of environmental hygiene.
