Patent ID: 8525373

Claim:
An electric toothbrush, comprising: a battery; an electromagnetic drive element connected to the battery, the electromagnetic drive element having an output axle; an oscillatory system, the system including a first oscillatory component and a second oscillatory component, the components capable of oscillating relative to one another around an axis of oscillation; and at least two elongate spring elements, each spring element having a first fastening point and a second fastening point spaced apart from one another, wherein the spring elements are leaf springs having surfaces that are elastic in a direction parallel to the axis of oscillation; and further wherein for each spring element the first fastening point is connected to the first oscillatory component and the second fastening point is connected to the second oscillatory component such that the spring elements intersect at the axis of oscillation, the axis of oscillation having an angle of intersection different from 0 degrees; and a brush head; wherein the first oscillatory component is connected to the electromagnetic drive element resulting in a rotary oscillatory movement of the brush head; and wherein the second oscillatory component is connected to the output axle resulting in a translatory oscillatory movement of the brush head.
