FIELD: medicine.
SUBSTANCE: invention relates to medical equipment and is intended for cleaning teeth. Power toothbrush contains a system for mitigating mechanical thrust, comprises an elongated housing open at a distal end and a proximal end; a frame, a motor disposed within the frame, elastic mounting support, multifunction coil of the charging winding. Frame has distal and proximal ends and is made slidable in the body. Motor includes a floating shaft having a distal end extending through the frame and the body and a proximal end extending within and forward the frame proximal end. Resilient motor mounting of the engine is disposed within the frame adjacent to the motor and includes a compression surface for holding the motor in the frame and a lower shock absorber disposed away from the proximal end of the shaft. Multi-functional charging coil is disposed in resilient contact with the proximal end of the frame at the proximal end of the body. Coil of the charging winding is connected with the inner wall of the proximal end of the body in a reciprocal arrangement in which the frame is compression-biased towards the distal end of the body. Coil of the charging winding comprises a bridge spring having two ends, the bridge spring being arranged transversely and being spaced from the proximal end of the coil. Bridge spring is in elastic contact with the proximal end of the frame.
EFFECT: invention makes it possible to control vibrations transmitted to the user through a toothbrush handle.
