Portable ultrasonic cleaner

Abstract

The portable cleaning device of the present invention utilizes a forward housing which includes an ultrasonic radiator and an ultraviolet radiator. A rearwardly located detergent spray reservoir can be used to optionally apply what may preferably be a dilute solution of soap material. Once solvent is added to the soiled area, the ultrasonic front located area can be placed in contact with the wetted garment area and energized to bring the ultrasonic radiator into direct contact with the solution in contact with the soiled area. This enables less energy to be utilized due to the close proximity to a limited liquid volume in the immediate area of the fabric and closely co-located with the soiled mass. Actuation of a ultraviolet radiator is activated simultaneously with the actuation of the ultrasonic radiator to begin to help with the odor problem from the outset of the cleaning activity. The combination of ultrasonic and ultraviolet energy input also provides energy to the solvent within the fabric to both increase the efficiency of cleaning and to assist the evaporation of solvent. The portable cleaning device can also be utilized with other solvents supplied by the user.

1 . A portable ultrasonic cleaner comprising: 
 a housing having a soiled fabric area engagement face;    an ultrasonic radiating structure carried at said engagement face;    a piezoelectric transducer in physical communication with said central ultrasonic radiating structure;    power driver circuitry in electrical contact with said piezoelectric transducer to ultrasonically drive said piezoelectric transducer; and    ultraviolet light output structure proximal to said ultrasonic radiating structure.
