A motor and a personal-care device having the motor. The motor has a motor carrier made at least partially from a sheet metal material, a movable motor part, and a spring element that couples the movable motor part with the motor carrier. The sheet metal material comprises at least one coupling area where the sheet metal material is folded so that its two layers are facing each other while each of the two layers comprises a slot, the slots being aligned with one another. A connection extension of the spring element extends through the aligned slots.

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.

A linear motor includes an armature mounted for driven linear oscillation substantially along a longitudinal direction; a secondary mass mounted for linear oscillation substantially along the longitudinal direction; and a coupling unit for coupling the armature and the secondary mass. The coupling unit includes at least two coupling spring assemblies and at least a coupling element, the coupling spring assemblies being arranged in planes perpendicular to the longitudinal direction and being spaced apart from each other, and the coupling element being fixedly connected with the coupling spring assemblies.

A personal care device having a handle having an engagement portion and a persona care attachment are described. The personal care attachment has a housing attached to the engagement portion and a contact element carrier. The contact element carrier is movably coupled to the housing. A plurality of contact elements is arranged on the contact element carrier, and wherein the personal care attachment is driven at a frequency of between about 150 Hz to about 175 Hz and has a sound intensity level of less than about 75 dB(A).

Personal care device

A personal hygiene device has a handle, a treatment head mounted for relative movement of at least a portion thereof with respect to the handle against a restoring force when a treatment force is applied in at least one direction onto the treatment head, a treatment-force-measurement unit for determining the applied treatment force comprising a light-emitting element, a light-sensitive element, and a light-changing element arranged at least partly in the light path between the light-emitting element and the light-sensitive element, wherein the light-changing element and at least one of the light-emitting element and light-sensitive element are arranged to be moved relatively to each other when at least the portion of the treatment head is moved.

Personal hygiene device having treatment-force-measurement unit

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 linear motor is disclosed. The linear motor includes an armature mounted for driven linear oscillation substantially along a longitudinal direction; a secondary mass mounted for linear oscillation substantially along the longitudinal direction; and a coupling unit for coupling the armature and the secondary mass. The coupling unit includes at least two coupling spring assemblies and at least a coupling element, the coupling spring assemblies being arranged in planes perpendicular to the longitudinal direction and being spaced apart from each other, and the coupling element being fixedly connected with the coupling spring assemblies.

A handle for a small electric handheld appliance in which the handle comprises a motor assembly disposed in the handle. The motor assembly comprises a generally L-shaped magnetic yoke formed from two substantially perpendicular surfaces, such that the two substantially perpendicular surfaces define a concave receiving portion. The motor assembly also comprises an iron core and a coil winding disposed substantially in the concave receiving portion, such that the iron core and the coil winding are free from contact with one of the two substantially perpendicular surfaces when the motor is at rest.

A linear electric motors including a housing, a first armature movable on a first essentially linear path with respect to the housing, and a second armature movable on a second essentially linear path with respect to the housing, wherein the first armature is mounted to the housing by a first mounting spring, wherein the first armature and the second armature are coupled to each other by a coupling spring, and wherein the second armature is mounted to the housing by a second mounting spring.

Linear electric motor

The present invention relates to an electric toothbrush, specifically the toothbrush handle of an electric toothbrush, with a handle housing, with a preferably rod-shaped drive transmitter which protrudes from a first side of the handle housing and on which a brush attachment can be secured, and with a drive motor for moving the drive transmitter, wherein the drive transmitter is mounted, by means of a bearing device in the interior of the handle housing, in the manner of a rocker arm such that the drive transmitter can be pivoted to-and-fro transverse to its longitudinal axis by the drive motor. The invention further relates to the whole toothbrush, comprising such a toothbrush handle part and a brush attachment secured to the drive transmitter thereof. According to the invention, the bearing device holds the drive transmitter so as to pivot about a rotation point lying outside the handle housing. Said rotation point is offset particularly far out from the handle housing, such that it comes to lie between the bristle array of the brush attachment and the front end of the handle in the area of the lips. In this way, an efficient cleaning movement with a large cleaning amplitude in the area of the bristle array can be combined with a low vibration amplitude of the toothbrush in the area of the lips.
