Abstract
An electric shaver having a cutter head with a plurality of cutting rotors driven by a drive train connectable to a motor. The number of tooling rotors is significantly increased while at the same time the size of the tooling rotors is significantly reduced, thus being able to define an approximately smooth surface by the front faces of the tooling rotors.
Claims20
A tool head for a personal care appliance, including a plurality of tool rotors rotatably supported about rotor axes and a drive train for rotatably driving said tooling rotors from a motor, wherein the tooling rotors are separately displaceably supported to elastically dive along their axes of rotation into a retracted position against a biasing force provided by biasing devices onto said tooling rotors, said support and biasing devices being configured to allow for a diving travel of at least about ¼ of a diameter of a tooling rotor.
