Abstract
A device such as an electric shaver, comprising a working head attached to a handle for moving the working head along a skin surface, said, wherein said at least one working tool is movable relative to said handle under a skin contact pressure by means of a support structure to allow for pivoting of the working head's skin contact contour relative to the handle, wherein a biasing device is provided for biasing said working tool.
Claims17
A personal care device, such as a hair removal device comprising a working head attached to a handle for moving the working head along a skin surface, said working head including at least one working tool defining a skin contact contour of the working head, wherein said at least one working tool is movable relative to said handle under a skin contact pressure by means of a support structure to allow for pivoting of the working head's skin contact contour relative to the handle, wherein a biasing device is provided for biasing and for increasing pivotal movement resistance of said working head, wherein an adjustment device including an adjustment actuator controlled by an electronic control unit is provided to adjust a pivoting stiffness of at least part of the working head.
A Method for controlling a personal care device such as a hair removal device like an electric shaver, comprising the following steps:
- detecting skin contact pressure of a working head against a user's skin by means of a skin contact pressure sensor during handling the personal care device when effecting a personal care treatment to a body surface,
- characterized by adjusting pivoting stiffness of at least part of the working head relative to a handle of the personal care device in response to the detected skin contact pressure by means of an adjustment actuator controlled by an electronic control unit during the personal care treatment.
