摘要
An ultrasonic hand-held cleaning device having a housing enclosing a casing, an energyzing winding about the casing, and a fluid conduit attached to the interior of the casing. A sleeve is insertably mounted into the end of the casing, and acts to support a connecting body at a spaced distance within the sleeve so as to form an annular space in fluid communication with the casing. A vibrator is attached at the casing end to the connecting 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 fluid moving through the annular space is sprayed out an annular nozzle around the tool which is itself vibrating ultrasonically as a result of reverbretory vibrations induced by the vibrator. In a second preferred embodiment the connecting body has a ring at its nodal point, the sleeve being cut out to accomodate the ring and having two longitudinal slots for the passage of fluid. A tubular insert for controlling the space between the connecting body and the sleeve at the nozzle is supported by the sleeve.
