  • Patent number: 10849402
    Abstract: The present invention is concerned with an epilator for removing body hair. The epilator comprises a body having a head section, a plucking cylinder which is rotatable about a first rotation axis in the head section for plucking hairs and at least one shaving blade for shaving off hairs, which is mounted in the head section movable with respect to the plucking cylinder. The at least one shaving blade is movable between a retracted position in which the at least one shaving blade does not protrude from the head section and an extended position in which the at least one shaving blade protrudes from the head section.

  • Patent number: 10779626
    Abstract: A skin treatment apparatus, preferably an epilator, comprising at least one detector for detecting approximation and/or contact with the skin and a control unit to actuate the device depending on the signal received from the detector. The control unit has at least one regulator which increases the speed of the drive unit upon detection of an increased resistance and/or current consumption by a sensor and/or decreases the speed of the drive unit upon detection of an decreased resistance and/or current consumption by a sensor.

  • Patent number: 10111509
    Abstract: An epilator having a body and a plucking cylinder which is rotatable about a rotation axis for plucking hair. The plucking cylinder is movable with respect to the body between an extended position and a retracted position. Further, the epilator has elastically deformable elements biasing the plucking cylinder and at least two rollers mounted on the same side of the body as the plucking cylinder with the plucking cylinder interposed between the rollers. When pressing the rollers and the plucking cylinder to a flat surface the force exerted by the rollers exceeds the force exerted by the plucking cylinder.

  • Patent number: 9888757
    Abstract: An attachment for an epilator or an epilator having at least a clamping unit for clamping and plucking hairs that is arranged for driven movement relative to a housing along a hair capture direction is disclosed. The clamping unit has a moveable clamping element having a clamping surface and a hair guiding surface and a fixed clamping element having a clamping surface and a hair guiding surfaced. The moveable clamping element and the fixed clamping element are arranged to be cyclically moveable between an open position in which the two clamping surfaces have a minimal distance such that a gap for receiving hairs is formed between them and a closed position in which the two clamping surfaces abut on each other. The two hair guiding surfaces form a funnel in front of the gap in the open position with respect to the hair capture direction.

  • Patent number: 9247798
    Abstract: An epilator (100) comprising an epilating unit (1) for plucking and/or pulling hair (51) out of the skin (50) over an epilating width (E). Such an epilator is disadvantageous in that typically not all of the hairs are detected by the epilating unit (1) and some remain in the skin after the epilation. A subsequent epilation would then be required. In order to solve this problem, the epilator (100) has a hair removal unit (2) following the epilating unit (1) in the direction (B) of use, such that, in at least one operating mode, the hair removal unit (2) removes the hairs (51) that have not been pulled out by the epilating unit (1).

  • Patent number: 8870896
    Abstract: The present invention discloses a hybrid epilator device that comprises a razor blade having a sharp edge for cutting hairs, an epilation cylinder comprising at least a pair of clamping elements that during operation are actuated by an actuation system between an open position and a closed position so that hairs can feed into the gap between the pair of clamping elements in the open position and are gripped and plucked out from the skin surface when the pair of clamping elements is in the closed position, and a manually operable adjustment mechanism that has a least a first adjustment and a second adjustment such that in the first adjustment and the second adjustment the skin surface can be simultaneously contacted by the sharp edge of the razor blade and an circumferential area of the epilation cylinder. This allows switching between two different epilation efficiencies of the epilation cylinder.

The clamping unit has a first clamping element having a clamping surface and a hair guiding surface and a second clamping element having a clamping surface and a hair guiding surface. The first clamping element and the second clamping element are arranged to be cyclically first between an open position in which the two clamping surfaces have a minimal distance such that a gap for receiving hairs is formed between them and a closed position in which the two clamping surfaces abut on each other. The two hair guiding surfaces form a funnel in front of the gap in the open position with respect to the hair capture direction.

  • Patent number: 8574242
    Abstract: The present invention is concerned with an epilator that comprises a housing, an epilation cylinder mounted at a head region of the housing for plucking hairs from the skin during operation, and an attachment detachably connected with the housing, which attachment comprises at least a shaving blade defining a use direction along which the shaving blade is to be drawn over the skin to shave off hairs. In the attached state the shaving blade is disposed behind the epilation cylinder with respect to the use direction so that during operation the epilation cylinder plucks hairs from the skin and the shaving blade contacts the skin to shave off hairs from the skin in successive order during a single stroke of the epilator over a skin area, wherein the attachment is connected with the housing in the head region such that the epilation cylinder is partially covered by the attachment and a non-covered part of the epilation cylinder extends into an aperture of the attachment.

  • Patent number: 8545518
    Abstract: The present invention is a hybrid epilator device comprising an epilation unit for gripping and plucking hairs from a skin surface and at least one razor blade edge to shave off hairs growing on the skin surface. The blade edge defines a use direction along which it is effectuated that hairs are shaved off when the razor blade is drawn over the skin surface during operation. The razor blade is arranged behind the epilation unit with respect to the use direction. The epilation unit and the razor blade are mounted for simultaneous contact with the skin surface, where during operation the epilation unit grips and plucks out hairs from the skin surface and subsequently the razor blade shaves off remaining hairs growing on the same skin surface in a single stroke.

  • Patent number: 8303603
    Abstract: A clamping device for a motor-driven epilation apparatus. The clamping device has a first clamping element with a first contact surface, in the region of which a three-dimensional clamping structure is provided. The clamping device has a second clamping element with a second contact surface. The contact surfaces of the clamping elements are intermittently brought in mutual clamping contact during the operation of the epilation apparatus. The hardness of the second clamping element in the region of the second contact surface is lower than that of the first clamping element in the region of the first contact surface.

  • Publication number: 20120078269
    Abstract: The invention is directed to an epilator apparatus for the removal of hair. The epilator apparatus comprises a tape, which adheres to the hairs as the apparatus is moved relative to the skin. The motion of the apparatus relative to the skin feeds the tape into the plucking zone where the tape with the hairs adhered thereto is redirected perpendicular to the skin. This redirection results in the hairs being plucked from the skin as the epilator apparatus is advanced.
