Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) In the following drawings:

(2) FIG. 1 shows a side view of a skin treatment device according to the invention;

(3) FIG. 2 shows a partially exploded and sectional view of a detail of the skin treatment device of FIG. 1; and

(4) FIG. 3 shows a perspective view of a skin treatment element according to an embodiment of the invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(5) With reference first to FIG. 1, a skin treatment device according to a preferred embodiment comprises a housing 10 and a treatment head 20. The housing 10 comprises a handle section 11 and may incorporate a drive mechanism like an electric motor, a battery, a control unit with a user interface and an interface for charging the battery.

(6) The treatment head 20 comprises a disc-shaped skin treatment element 21. The disc-shaped skin treatment element 21 has an axial first skin treatment surface 22 which is provided on a main side of the disc-shaped skin treatment element 21 is provided with a plurality of bristles to provide a brush-type first surface characteristic. This axial first skin treatment surface 22 has a flat, circular shape and extends perpendicularly to a rotational axis 100. The first skin treatment surface 22 allows a combined cleaning treatment and massage treatment of the skin if the disc-shaped treatment element 21 is put into rotational movement about the rotational axis 100 by the drive mechanism incorporated in the housing 10. The terms “axial” and “radial” are to be understood to refer to the rotational axis 100.

(7) Further, the skin treatment element 21 comprises a radial second skin treatment surface 25 which extends along the circumference of the disc-shaped skin treatment element 21 perpendicularly to a radial direction with respect to the rotation axis 100. This radial second skin treatment surface 25 has an axial width parallel to the rotational axis 100 and extends along the whole periphery of the disc-shaped skin treatment element 21. The outer peripheral surface of the radial second skin treatment surface is coated with abrasive particles to form an abrasive second surface characteristic with a predefined grit size which is constant over the whole circumference and the axial extension of the radial skin treatment surface. It is to be understood that other types of skin treatment surfaces, like brush-type surfaces or polishing surfaces, could be provided at the radial skin treatment surface instead of the abrasive surface.

(8) As can be seen from FIG. 2, the radial second skin treatment surface 25 is provided on a ring-shaped tool element 27 which can be coupled to an attachment base 26 of the skin treatment element 21. The attachment base 26 has a cylindrical outer geometry with a plurality of protrusions 26a extending in a radial direction with respect to the rotational axis 100. Said protrusions 26a interact in a form-locking manner with corresponding recesses 27a provided at the inner surface of the tool element 27. By virtue of this, a secure and durable coupling of the tool element 27 to the attachment base 26 is reached.

(9) The detachable design of the tool element 27 from the attachment base 26 allows for easy change and replacement of the radial second skin treatment surface 25. By virtue of this, the radial second skin treatment surface may be replaced if it is worn or abraded or contaminated, or it may be exchanged if another surface characteristic like, e.g., a finer or coarser grit size, a brush-type surface characteristic or a polishing surface characteristic is required.

(10) With reference to FIG. 3, a skin treatment element 121 may comprise an axial first skin treatment surface having a first inner circular region 122a with a first surface characteristic and a second ring-shaped region 122b with a second surface characteristic that is different from the first surface characteristic. The first surface characteristic may have a relatively coarse grit size like, e.g., an ANSI 120 grit size, whilst the second surface characteristic may have a relatively fine grit size like, e.g., an ANSI 400 grit size, which is functional at relatively high speeds. A ring-shaped space 123 is free of a surface characteristic adapted and intended to effect a skin treatment, and comprises, i.e., a smooth ring arranged between the two regions 122a and 122b to allow selective use of either region 122a or region 122b. Further, a second skin treatment surface 125, having a polishing felt-like structure and being oriented radially with respect to the rotational axis 100, is provided on the circumferential surface of the skin treatment element 121. A ring-shaped free space 124 is positioned at the edge region to prevent unintended contact and application of the first skin treatment surface region 122b when the second skin treatment surface 125 is used.

(11) Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims.

(12) In the claims, the word “comprising” does not exclude other elements or steps, and the indefinite article “a” or “an” does not exclude a plurality.

(13) Any reference signs in the claims should not be construed as limiting the scope.
