The invention relates to an electrically driven device, for example an electric hair removal device, such as a wet or dry shaver, an electric toothbrush or an electric skin treatment device. The electrically driven device comprises a housing having a chassis, wherein the chassis comprises an electric motor having a first drive shaft, a battery unit, and an oscillating body having a second drive shaft. A first longitudinal axis is defined arranged along the second drive shaft, a second longitudinal axis is defined arranged along the first drive shaft, and a third longitudinal axis is defined arranged through the center of the body of the battery unit, wherein the second longitudinal axis and/or the third longitudinal axis are parallel offset to the first longitudinal axis.

An electric shaver with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft having a second rotary axis. The driven shaft is indirectly coupled to the drive shaft by a gear mechanism capable of converting a rotary motion of the drive shaft into a reciprocating motion of the driven shaft.

An electrically driven device provided with a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft mounted in the housing for performing a pivoting is disclosed. The driven shaft is indirectly coupled to the drive shaft by means of a gear mechanism converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The gear mechanism comprises one intermediate shaft having a second rotary axis extending in the longitudinal direction of the intermediate shaft and at least one crank arm coupled to the drive pin. The crank arm is pivotably mounted in the housing and is coupled to the intermediate shaft thereby converting a rotary motion of the drive shaft into a reciprocating pivoting of the intermediate shaft about the second rotary axis. The intermediate shaft is coupled to the at least one driven shaft by means of a pivotable bridge such that the intermediate shaft is offset with respect to the at least one driven shaft.

The invention refers to an electric shaver with a first cutter element and a second cutter element which are movable relative to each other in an oscillating manner along a first horizontal cutter oscillation axis. Each cutter unit is mounted in the cartridge pivotably about a second horizontal tilting axis and axially displaceably parallel to a vertical axis. The first horizontal cutter oscillation axis is perpendicular to the vertical axis and perpendicular to the second horizontal tilting axis.

The invention refers to an electric shaver comprising a shaver housing, a shaver head and at least one cartridge mounted in or on said shaver housing. The adaption of the cutter element to the contour of the skin to be shaved is improved by permitting at least one additional movement of the at least one cutter unit relative to the shaver head.

An electrically-driven razor includes a handle and a slim, lightweight head. The handle includes a housing, a motor, a transmission, at least one driven shaft, and a coupling. The motor is contained substantially within the housing. The head includes a skin-engaging portion. The coupling links the head to the housing. The at least one driven shaft extends into the head. The transmission is constructed to translate rotary motion of the motor to reciprocating motion of the at least one driven shaft. The head is pivotable in at least two dimensions, relative to the housing.
