▎ 摘　　要

NOVELTY - The device has an ultrasonic generator (4) connected with a measuring and controlling instrument (2) through a conduit (5). An outer wall of a lifting mechanism is connected with an outer wall of the ultrasonic generator. A top unit of a base (1) is connected with a supporting frame (10). Horizontal end of a top unit of the supporting frame is fixedly connected with a telescopic rod (8). An outer wall of the telescopic rod is connected with a spring (11) that is elastically connected with the supporting frame. A top unit of the outer wall of the telescopic rod is movably connected with a rocker (9). A bottom unit of the rocker is connected with the spring. An inner surface wall of a cleaning sleeve (14) is fixedly connected with a cushion layer and fixed with an outer surface wall of a sealing cover (13). USE - Ultrasonic stripping device for preparing graphene. Uses include but are not limited to optical, electrical, mechanical, micro-nano processing, energy, biomedicine and drug delivery applications. ADVANTAGE - The device presses the rocker to compress the spring downward, separates the cleaning sleeve from the sealing cover, rotates the rocker for 180 degrees in axial direction, locates the cleaning sleeve below the ultrasonic generator, artificially cancels restraining force of the rocker, allows the spring reset and the rocker to drive the cleaning sleeve on a bottom outer wall of the ultrasonic generator, utilizes the cushion layer of the inner wall of the cleaning sleeve to absorb solvent adhered to the outer wall of the ultrasonic generator, and presses and rotates the rocker to reset when performing subsequent experiment, so as to combine the released cleaning sleeve with the sealing cover, so that external impurity is avoided to attach in the cleaning sleeve, thus finishing cleaning of the ultrasonic generator in a convenient manner, and hence improving use stability. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of an ultrasonic stripping device for preparing graphene in partial section. 1Base 2Measuring and controlling instrument 3Lifting cabin 4Ultrasonic generator 5Conduit 6Connecting sleeve 7Blocking frame 8Telescopic rod 9Rocker 10Supporting frame 11Spring 12Fixing frame 13Sealing cover 14Cleaning sleeve 15Limiting ring 16Threaded sleeve 17Transmission rod 18First gear 19Second gear 20Limiting cabin
