Abstract
Abstract An ultrasonic cleaning device is provided which comprises a base unit and a cleaning chamber unit removably mounted on the base unit. An ultrasonic frequency transducer is attached to the bottom of a cleaning chamber, and the high frequency energy output of a high frequency oscillator circuit which is disposed within the base unit together with a power supply circuit is transmitted to the ultrasonic frequency transducer by electromagnetic induction coupling.
