摘要：An ultrasonic hand-held cleaning device having a housing enclosing a casing, anenergyzing winding about the casing, and a fluid conduit attached to the interior of thecasing. A sleeve is insertably mounted into the end of the casing, and acts to support aconnecting body at a spaced distance within the sleeve so as to form an annular space influid communication with the casing. A vibrator is attached at the casing end to theconnecting body and is therefore located in the casing opposite the energyzing winding.A cleaning tool is attached at the other end of the connecting body. In one version fluidmoving through the annular space is sprayed out an annular nozzle around the toolwhich is itself vibrating ultrasonically as a result of reverbretory vibrations induced by thevibrator. In a second preferred embodiment the connecting body has a ring at its nodalpoint, the sleeve being cut out to accomodate the ring and having two longitudinal slotsfor the passage of fluid. A tubular insert for controlling the space between theconnecting body and the sleeve at the nozzle is supported by the sleeve.
