ELECTRIC TOOTHBRUSH Russian patent published in 2008 - IPC A61C17/34 

FIELD: personal demand and household items.

SUBSTANCE: electrical toothbrush incorporates a long handle, with a motor arranged therein, a head, a bristle mobile carrier located on it, a neck, which lies between the handle and the head, and a shaft. The shaft can be directly connected with the bristle carrier and, in the process of work, with the motor, so that shaft moving makes the bristle carrier move about an axis, at the bottom of perpendicular head axial axis, and produce to-and-fro motion about an axis at the bottom of perpendicular head axial axis. The bristle mobile carrier can have an inclined surface arranged on its lower side, and the head can incorporate a pole, which are coupled to slip. The head can move about the handle. The shaft can be directly connected with the motor and the bristle carrier and coupled with movable neck so that the shaft moving makes the bristle carrier vibrate about an axis at the bottom of perpendicular head axial axis, and the neck and head but move in the transversal line to the axial axis of the handle. The shaft can be repeatedly coupled and uncoupled with the neck.

EFFECT: higher efficiency of cleaning due to additional movement combinations.
