An electrically operable clipper having a body portion and a head portion, wherein the head portion includes a movable cutter and a fixed comb. The clipper includes an internally located electric motor operable to move the movable cutter. The electric motor is provided with a first and second air moving structure operable to move air over and through the electric motor, in use.

An electric shaver, comprising an elongated handle for manually moving the personal care device along a body surface, a working head attached to said handle for effecting a personal care treatment to said body surface, at least one detector for detecting at least one behavioral parameter indicative of a user's behavior when handling the personal care device, and an adjusting mechanism for adjusting at least one working parameter of the working head in response to the detected behavioral parameter.

A small appliance device, in particular a body-care appliance device, in particular a shaving apparatus device, beard-trimming device, hair-trimming device, epilating appliance device, tattooing appliance device, toothbrush device or the like, has a drive unit which comprises at least one drive element, wherein the drive element comprises at least one magnetically shape-shiftable material.

A wet shaving device comprising a motor; an actuator configured to vary the speed of the motor; a rotary blade module having at least one cutting element; and a drive train assembly including at least one shaft operatively coupling the motor and the rotary blade module, wherein the at least one shaft may be configured to transfer the rotational movement of the motor to the rotary blade module.

An actuator has: an affixed section having a coil; a first mobile section that is elastically held and disposed so as to allow movement in the axial direction inside one end of the coil, and has a first magnet magnetized in the axial direction of the coil and disposed on one end in the axial direction; and a second mobile section that is elastically held and disposed so as to allow movement in the axial direction inside another end of the coil, and has a second magnet magnetized in the axial direction and disposed on the other end in the axial direction. The first and second magnets are disposed such that identical magnetic poles are in the same direction in the axial direction, and the first and second mobile sections move in opposite directions along the same axis when a current is applied to the coil.

Electrical hair removal device and method for determining the time behavior of a cyclic motor process during use of the electrical hair removal device with a motor-driven hair cutting unit by measuring the motor current. Parallel to measuring the motor current, the induced voltage of the motor is measured and a timing property of the induced voltage is evaluated, wherein the duration of a time pattern in the induced voltage is analyzed as timing property of the induced voltage. A cutting activity of the electrical hair removal device during use is determined based on the evaluated timing property of the induced voltage, and a force applied onto skin during use of the electrical hair removal device is determined based on the measured motor current and, optionally, on the determined cutting activity.

A pivot motor has a stator and an armature. The armature has an assembly of two spaced permanent magnets and a triangular flux bridge on one end. Magnetic flux is generated by passing alternating current through an electrical coil in the stator. The flux flows through the permanent magnets to generate electromotive force that vibrates the armature. The triangular flux bridge adjacent the magnets facilitates the flux flow, increasing motor power under typical load conditions and motor efficiency.

The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a drive unit having first and second drive components adapted to magnetically interact with each other, and a magnetic shielding at least partially surrounding the drive unit. Said magnetic shielding is formed by structural parts supporting the drive unit and/or transmitting drive movements of the drive unit, wherein such structural parts are made of a soft magnetic material. More particularly, a mounting frame and a transmitter frame together form a magnetic shielding cage which is movable as the mounting frame and the transmitter frame are movable relative to each other.

The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a magnetic linear drive unit having first and second drive components supported for linear displacement relative to each other by a first spring device and adapted to magnetically interact with each other, and a second spring device for movably linking the drive unit to a structural element of the appliance. The first spring device is made from plastics such as long-chained PPS, whereas the second spring device is made from steel.

The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a magnetic linear drive unit having first and second drive components supported for linear displacement relative to each other by a spring device and adapted to magnetically interact with each other. Said spring device includes a ring element made in one piece from plastic including at least one pair of leaf springs and a pair of cross-bars extending crosswise to said leaf springs and connecting said leaf springs to each other.
