DETAILED DESCRIPTION OF THE INVENTION

[0029] FIG. 1 shows an electric hair removal device which is embodied as an electric shaver and two different attachments therefore each not connected with the shaver. Said shaver comprises a shaver handle 1 and a shaver head 2. The shaver head 2 comprises a shaver head base 3 which is connectable with an attachment 4, 5 by a snap fit 17 or other connection. As a first attachment 4 there is provided a skin treatment attachment. As a second attachment 5 there is provided a hair removal tool 6 which comprises several hair cutting units 30, 31, 32. As hair cutting units short hair and/or long hair cutting units may be arranged in the second attachment each comprising a lower, actively driven blade which may linearly oscillate and an upper blade.

[0030] The handle 1 of the shaver comprises a motor 9 energized by a battery. The motor is of the rotary or linear type. A drive train 10 couples the motor drive with one or more output drive's 11. The motor 9 of FIG. 1 is of the linear type, so that the output drive's 11 move back and forth along a linear pathsee arrow's 50. The linear motor 9 comprises an electromagnet 14 and a permanent magnet 15 moving relative to each other (see FIG. 2). Lower blade connectors 35 are provided at each end of the output drive's 11.

[0031] FIG. 2 shows a cross section through the skin treatment head 4 connected with head base 3 along the oscillation direction 50 or along axis B-B of FIG. 3. Schematically illustrated is the motor 9 with drive train 10 coupled to the head 2. The drive train 10 comprises an oscillation bridgeas part of the head 2linearly guiding the output dive's 11.

[0032] A substantially U-shaped head support frame 12 is provided for supporting the head 2 with the handle 1. The lower end of the head support frame 12 is fixedly connected with a housing 13 of the motor 9. The upper ends of the head support frame 12 are pivotably connected with the housing 7 of the head base 3 at pivot supports 33. The pivotal axis is parallel with the oscillation direction 50 of the lower blades.

[0033] The motor vibrations are introduced into the head as a further effect of the connection between motor housing 13 and head housing 7 by head support frame 12, so that the head is actively driven with respect to the motor vibrations. Moreover, the skin treatment attachment is also passively vibrating due to the back and forth movement of the output drive 11 with the inner space 8 of the head. At least one of the above or as here shown both sources for generating vibrations in the skin treatment head is provided. The frequency of the vibrations may range between 50 and 300 Hz or optionally between 100 and 200 Hz.

[0034] FIG. 3 shows a cross-section through the skin treatment head connected with the head base 3 and a schematic connection with the motor 9 of the handle 1 along axis A-A of FIG. 1 or orthogonal to the oscillation direction along arrows 50. The first attachment 4 comprises one ore more snap fit projections 19 which snap with snap fit hooks 17 which are pivotable around axis 18 and provided on the head base 3, thus forming one or more snap fit connections 16.

[0035] The skin treatment attachment 4 may be of any type suitable for treating the skin. It's skin contact surface 26 may be thus provided with hair or rubber bristles or may be a substantially flat surface. The skin treatment attachment illustrated with FIGS. 1-7 is of the type with a substantially flat skin contact surface 26.

[0036] As shown in FIGS. 1-7 the skin treatment attachment is provided with a base part 22 made from plastic and a treatment part 21 made from metal and more preferably stainless steel. Both the base part 22 and the treatment part 21 are rectangular in top view (with rounded edges) and substantially tub shaped. Said treatment part 21 lower surface is shaped to fit an upper shape of the base part 22. The base part 22 is provided with a permanent magnet 20 which is embedded in a recess or indentation provided in the outer top surface of the base part 22. As best illustrated with FIGS. 4 and 5 the magnet is surrounded by a rectangular glue ring 23 which allows both fixation of the treatment part onto the magnet the glue and the base part but also provides water sealing of the magnet which is sandwiched between both the base part 22 and the treatment part 21. The treatment part 21 is thus forming a cap onto the base part 22.

[0037] The magnet 20 is provided with a magnetic array comprising multiple pole directions and it is optionally a permanent magnet. A kit may comprise a skin cream 40see FIG. 8provided with diamagnetic active ingredients which are more permeable to human skin by magnetophoresis interacting with the magnet 20 of the skin treatment attachment 4see FIGS. 1-7. The magnetic property may be ?s<1,3 at the skin contact side 26 adjacent to the magnet 20 and the treatment part 21.

[0038] The metal skin treatment part 21 is less than 1 mm, or less than 0,6 mm or around 0,4 mm thick in order to provide a small distance between magnetic array and skin to be treated and thus a maximum effect of the magnetophoretic function with the cream. Accordingly, the penetration of cosmetic ingredients of the cream is enhanced. The treatment part 21 may be coated, galvanized, or lacquered but is preferably not surface treated, uncoated, not galvanized and not lacquered in order to keep the smooth surface property independent from such coating defects which may happen over time.

[0039] The skin contact side 26 of the treatment part 21 is further provided with several, preferably 2-5, ring-shaped projections 25 which ring is substantially rectangular with rounded edges. Said projections 25 project from said flat skin contact side (26) by p=0,1 to 2 mm, or by p=0,1 to 1 mm or by p=0,1 to 0,5 mm. The outer rim portion of the treatment part 21 is rounded with a radius of 2 to 10 mm in order to provide a smooth skin feel.

[0040] The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as 40 mm is intended to mean about 40 mm.
