Patent ID: 7815780

Claim:
An ultrasonic cleaning device for cleaning and removal of mineral deposits on one or more submerged electrodes of a device containing the one or more electrodes, the electrode containing device comprising a housing having an inlet port and an outlet port for allowing a flow of fluid to pass through the housing and over the one or more submerged electrodes, the ultrasonic cleaning device comprising: a flexible membrane soft coupled with respect to the housing and covering an aperture in the housing, a first side of the membrane in contact with the fluid in the housing and a second side opposite the first side and not in contact with the fluid in the housing; and an ultrasonic transducer operatively coupled to the second side of the membrane, and not directly connected to the housing, to cause ultrasonic vibrations in the membrane and flexing of the membrane for generating and projecting ultrasonic waves in the fluid directed at the one or more submerged electrodes.
