Ultrasonic cleaning device for removing undesirable particles from an object

摘要

A cleaning device for cleaning an object includes an inner vessel configured to contain a first liquid and the object. The cleaning device also includes an external vessel configured to contain a second liquid and the inner vessel. The second liquid is acoustically coupled to the first liquid. At least one transducer is acoustically coupled to the external vessel and configured to generate acoustical energy which is transferred to the object through the external vessel, a second liquid, the inner vessel and the first liquid. The first liquid has a dissolved gas concentration of a first gas and the second liquid has a dissolved gas concentration of a second gas.
