Abstract

The invention relates to a hair-removing device with a movable actuator head and/or at least one movable actuator support, which have at least one actuator element for removing hair on a skin surface. The particular feature of the invention is that a detecting device for detecting a parameter which relates to the position of the actuator element relative to the skin surface is provided as well as at least one actively actuated positioning device for modifying the position of the actuator head and/or the actuator support and a control device for activating the positioning device according to the detected parameter.

Claims (12)

1. An electric razor for removing hair from a skin surface, comprising:

a movable actuator head, wherein the movable actuator head defines a first pivoting axis about which the head may pivot;

a movable actuator element, moveably attached to said movable actuator head;

a pivotable support, wherein the pivotable support defines a second pivoting axis about which the actuator element may pivot;

a detecting device for detecting a parameter which relates to the position of the actuator element relative to the skin surface;

an actively actuated positioning device for modifying the position of the movable actuator head the movable actuator element, or the movable actuator head and the movable actuator element; and a control device for activating the positioning device according to the detected parameter;

wherein said actuator head is a pivotable shearing head said shearing head connected to said movable actuator element, said movable actuator element comprising, a first shearing foil, a second shearing foil and a central cutter arranged between the shearing foils; said electric razor further comprising a housing, which a user holds in the hand; and wherein said shearing foils and the central cutter are respectively connected to said detecting device, which comprises an electronic circuit, in an electrically conducting manner, the first shearing foil being connected to a first transistor, the second shearing foil being connected to a second transitor and the central cutter being connected to a third transitor, the emitters of the transistors being connected to ground; the firs transistor being connected to an input of a control logic and to a firs collector resistor; the second transistor being connected to an input of the control logic and to a second collector resistor and the third transistor being connected to an input of the control logic and to a third collector resistor; said control logic having an input which is connected via a driver stage to said positioning device; and wherein said collector resistors are also connected to one another and are at an electric potential; wherein the housing is at least partially electrically conducting and comprises an electrical connection to the second shearing foil via the user.

2. The device of claim 1 wherein the actuator head is pivotably suspended.

3. The device of claim 1 wherein the actuator head is displaceable in at least one plane.

4. The device of claim 3 further comprising a movable actuator support attached to the actuator head, wherein the actuator support is displaceable in at least one plane.

5. The device of claim 1 further comprising a long-hair cutter arranged on the actuator head, the long-hair cutter comprising a comb and a blade.

6. The device of claim 1 further comprising at least one plucking unit attached to the actuator head.
