    摘要: A TOOTHBRUSH ENERGIZED BY AN INTERMITTENT LIQUID PULSE STREAM COMPRISES A HANDLE IN WHICH A HYDRAULIC MOTOR OF THE EXPANSIBLE CHAMBER TYPE IS MOUNTED AND CONNECTED TO DRIVE THE TOOTHBRUSH WITH BACK AND FORTH MOVEMENT. THE RECIPROCATING MOVEMENT OF THE MOTOR IS CONVERTED TO OSCILLATING MOVEMENT OF THE BRUSH BY A HELICAL POST DRIVEN BY THE MOTOR AND SLIDABLY ENGAGING A SLEEVE ROTATABLY MOUNTED IN THE HANDLE AND TO WHICH THE BRUSH IS ATTACHED. THE ENERGIZING PULSE STREAM IS CONNECTED IN DIRECT COMMUNICATION WITH THE EXPANSIBLE CHAMBER TO DRIVE THE MOTOR.
