Abstract: The present invention relates to a hair cutter such as electric shaver and/or electric trimmer, comprising a suspension spring mechanism including at least one elongated leaf spring which is rigidly attached, with one end portion, to a first end portion or edge portion of a cutter unit and, with another end portion, to a cutter head frame at a spring support portion thereof adjacent to a second end portion or edge portion of the cutter unit opposite to the first end portion or edge portion thereof. Despite such eccentric attachment of the leaf spring to the cutter unit and the asymmetric layout of the spring mechanism, the elastic support structure of the at least one cutter unit nevertheless may be configured to provide for a symmetric self-adaption, in particular symmetric micro diving and/or micro tilting.

Abstract: The present invention relates a method of manufacturing a hair cutting device with an outer metal shell, comprising the steps of forming the outer metal shell into a desired shape and mounting functional components for performing or helping to perform a personal care treatment into and/or onto said formed outer metal shell. Said forming the outer metal shell includes a hydraulic pressure forming step.

Abstract: The present invention relates to the field of battery powered electrical appliances or personal hygiene, in particular to a hair removal device such as an electric shaver or epilator as well as an electric toothbrush. A control device for a battery powered electrical appliance for personal hygiene is described, wherein the control device is adapted to cause the battery powered electrical appliance to perform automated contact fritting of a battery contact by controlling the battery powered electrical appliance such that a current pulse exceeding a wetting threshold is applied across the battery contact during a standby period.

Abstract: An electric shaver, comprising an elongated housing receiving an electric motor and/or an electric power source, a working head attached to said housing, wherein said housing includes an elongated base element and a cover element closing said base element and surrounding a connection connecting said electric motor and/or said electric power source to said working head, wherein said cover element is sealed to said base element and/or to said connection by at least one seal.

Abstract: An electric shaver with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft having a second rotary axis. The driven shaft is indirectly coupled to the drive shaft by a gear mechanism capable of converting a rotary motion of the drive shaft into a reciprocating motion of the driven shaft.
