Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Embodiments of the invention will now be described, by way of example only, with reference to the accompanying schematic drawings in which corresponding reference symbols indicate corresponding parts, and in which:

(2) FIG. 1 schematically depicts an embodiment of the body care device; and

(3) FIGS. 2a-2f schematically depicts some embodiments and variants of the treatment head.

(4) The schematic drawings are not necessarily to scale.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(5) FIG. 1 schematically depicts an embodiment of the device, indicated with reference 1, especially for use in cleansing the skin, such as the skin of a face. Here, the device, especially for treating the skin, comprises a housing 100 and a skin treatment head 200 rotatably associated with said housing 100. The housing 100 encloses an actuator 110 configured to rotate said skin treatment head 200. Further, the housing includes in this embodiment a rechargeable battery 321. Yet further, the housing 100 may comprise one or more LED indicators 323 and a user interface 324. Further, the housing may include a means 322 for receiving electrical power for charging the battery, such as a socket known in the art.

(6) The skin treatment head 200 comprises bristles 211 associated with the treatment head 200. The bristles 211 may be configured in tufts, see also below.

(7) The actuator 110 is especially configured to rotate the skin treatment head 200 about an axis A (axis of rotation). This axis may be parallel, but is not necessary parallel to a body axis of the device. The skin treatment head 200 comprises a first region 210 comprising a plurality of bristles 211. The skin treatment head 200 also comprises a second region 220 comprising a porous flexible material 221. The porous flexible material 221 may comprises a sponge 222, such as a natural sponge or a synthetic sponge.

(8) Reference 201 indicates a treatment head surface. The bristles 211 extend from this surface.

(9) FIG. 2a schematically depicts an embodiment of the treatment head 200, in top view, wherein the first region 210 circumferentially surrounds the second region 220. Of course, other configurations are also possible. Here, the indication of the axis A coincides with the center, indicated with C, of the treatment head 200.

(10) In general, the treatment head 200 will have a circular cross-section.

(11) FIG. 2b schematically depicts an embodiment of the treatment head 200 in cross-sectional view. The first region 210 occupies a first area size A1 of the treatment head 200 and the second region 220 occupies a second area size A2. In variants, the first region 210 and the second region 220 have an area size ratio of the first area size to the second area size 0.1≤A1/A2≤100, such as 0.2≤A1/A2≤10, like especially 0.2≤A1/A2≤5.

(12) Further, the bristles 211 have a bristle height hl relative to the treatment head surface 201. The porous flexible material 221 has a sponge height h2 relative to said treatment head surface 201. In variants, the bristles 211 and the porous flexible material 221 have a height ratio of the bristle height to the sponge height 0.5≤h1/h2≤2.

(13) The porous flexible material 221 may have a larger height h2 than the height h1 of adjacent bristles, indicated with reference 211′ (which are bristles configured closest to the porous flexible material). In yet other embodiments, the porous flexible material 221 may have a smaller height h2 than the height h1 of adjacent bristles 211′ (as schematically indicated in FIG. 2b). The edge of the treatment head 200 is indicated with reference E.

(14) FIG. 2c schematically depicts in a cross-sectional view an embodiment of the treatment head 200 comprising two or more first regions 210, wherein a first first region 210a and a second first region 210b have bristles 211 having different bristle heights h1. The first first region 210a includes bristles having a bristle height h11. The bristles 211 of the second first region 210b have a bristle height h12. In variants, h11<h12; in other variants, as schematically depicted here, h11<h12. In further variants, h11<h12<h2. In other variants, as schematically depicted here, h11<h12<h2.

(15) More than two first regions may be available. FIG. 2d schematically depicts an embodiment with the heights varying from the center to the edge.

(16) The area A1 of the first region is especially the sum of the areas occupied by all bristles 211, irrespective of their specific first regions. The treatment head 200 including the bristles 211 may also be indicated as “brush”.

(17) FIG. 2d schematically depicts an embodiment wherein the treatment head 200 has curved treatment head surface 201. In the schematically depicted embodiment of FIG. 2d, the bristles 211 are configured to provide a curved brush.

(18) Embodiments described herein may especially include a centrosymmetrical arrangement of the first region 210 and the second region 220, see e.g. FIG. 2a, but also FIGS. 1, 2b, 2c may refer to such embodiments. Would FIG. 2d schematically depict a treatment head 200 having a centrosymmetrical configuration, then the treatment head surface 201 may be curved in two directions. In FIGS. 2c radially more distant bristles have a larger height (than radially less distant bristles), whereas in FIG. 2d radially more distant bristles have a smaller height (than radially less distant bristles). The bristles 211 closest to the edge E are configured radially most distant (from the center C).

(19) FIG. 2e, however, schematically depicts an embodiment of a non-centrosymmetrical configuration of the first region 210 and the second region 220. Of course, other configurations may also be possible.

(20) FIG. 2f schematically depicts a top view of a variant as schematically depicted in FIG. 2c.
