The present invention relates to the field of small electrical appliances such as battery powered electrical appliances for personal hygiene, in particular to a hair removal device such as an electric shaver or epilator as well as an electric toothbrush. The small electrical appliance comprises an electric load, wherein the electric load heats up during operation; a measuring circuitry for measuring an electrical parameter of the electric load; a temperature sensor arranged spatially separated from the electric load; and control circuitry adapted to protect the electric load from overheating by controlling the electric load based on the electrical parameter of the electric load and an output of the temperature sensor.

Small electrical appliance with protective circuit

A hair removal device, in particular an electric shaver, comprising a working head attached to a handle for moving the working head along a skin surface, said working head including at least a pair of short hair cutters and at least one trimmer neighboring at least one of said short hair cutters, wherein said short hair cutters and said trimmer are movable relative to said handle under a skin contact pressure.

Hair removal device

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.

Electric appliance for personal care

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. The spring device includes at least one leaf spring having a constricted section in a central region of the leaf spring, wherein surfaces of the at least one leaf spring neighboring the constricted section are shaped convex. Such convex surfaces may have a parabolic contour.

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.

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 and adapted to magnetically interact with each other, wherein a drive support is provided for supporting the drive unit onto a mounting structure. The drive support supporting the drive unit onto a mounting structure of the installation environment is adapted to provide for at least one axis of rotation for the drive unit allowing said drive unit to rotate relative to the mounting structure, said axis of rotation being spaced apart from the drive unit to provide for a transmission ratio increasing or decreasing the oscillation amplitude of the functional element driven by the drive unit vis-&#xe0;-vis the oscillation amplitude of the drive unit.

A shaving unit for a dry shaver includes at least one outer cutter and one under cutter. Driven by a motor, the outer cutter and the under cutter are movable relative to each other in an oscillatory motion. The under cutter and the outer cutter, which are biased into relative engagement by at least one spring, slide along a common contact surface. The spring is arranged in such a way that its biasing force always acts at an angle to the direction of oscillation.

Oscillatory shaver

A cutting head for an electric razor is provided. The cutting head has at least one upper blade and a lower blade associated with the upper blade, which upper and lower blades are movably supported relative to one another and can be driven accordingly by a drive device. The upper blade has a contact surface for the skin to be shaved, which contact surface is formed by a plurality of webs that are each bounded by slots. The longitudinal extent of the webs runs substantially perpendicular to a threading edge bounding the contact surface. The contact surface is designed to be concave and rises towards the threading edge, where the threading edge has an outer radius and this outer radius encloses an angle of less than 90&#xb0;.

Cutting head for an electric razor

An electric shaving apparatus including a housing and a shaving head. The shaving head is coupled to the housing by at least one first elastic element and includes at least one first shaving element. The electric shaving apparatus includes in addition an electric motor for generating an oscillatory motion of the shaving head and an oscillatory motion differing therefrom of at least one second shaving element. The electric motor includes two drive components of which a first drive component is adapted to be driven to oscillate relative to a second drive component. One of the drive components is connected to the second shaving element. The second shaving element or a drive part connected thereto is equipped with an elastic connection to the shaving head.

Electric shaving apparatus

The invention relates to a lower cutter () which, together with an associated upper cutter (), forms the shaving head of a dry shaver. The upper cutter is designed in the form of a perforated foil () which at least partially encloses the lower cutter () and is prestressed against the same. The lower cutter () has a plurality of spaced-apart blades having cutting edges () in the form of strips between two peripheral regions (). The lower cutter () is essentially U-shaped in cross section. The width of the strip tapers monotonously from the two peripheral regions () in the direction of the center (Z).

Lower cutter for the shaving head of a dry shaver

The present invention is directed to an electric shaver having a shaver housing, and a shaving head housing that is connected to the shaver housing for pivotal movement between two end positions. The shaving head housing carries at least two shaving assemblies, of which at least one shaving assembly is retractable into the housing to a first, retracted position, and elastically biased toward a second, extended position, such that extension of the at least one shaving assembly is a function of contact pressure applied by a user. Actuating elements carried by the shaving head housing control a maximum degree of extension of the at least one shaving assembly as a function of a pivot angle between the shaver housing and the shaving head housing.

Electric shaver

An electric shaver has a pivotally mounted longhair cutter unit that is pivoted outward into an operating position by motion of an operating switch of the shaver via an actuator that also causes the cutting blades of the longhair cutter unit to extend from the longhair cutter housing. Because the longhair cutter retracts into the longhair cutter housing when the longhair cutter unit is folded shut, the sharp edges of the blades are protected.
