Embodiment Construction

[0023] in the description with Figure 1 to Figure 15 Before referring to advantageous embodiments of the invention, the different aspects of the invention will be described in more detail. These aspects disclose further features, advantages and possibilities of the uses of the invention which may be combined in any useful combination. All features described and / or shown in the drawings are subject-matter of the present invention irrespective of the grouping of features in the claims and / or their back-references.

[0024] In electric razors, especially those comprising a foil-type upper cutter and a lower cutter having several blades oscillating relative to the upper cutter, the hair removal result can be measured by comparing the cutter elements relative to each other. Large oscillation stroke to improve. For example, in an electric razor with a foil-type upper cutter and a lower cutter with several blades, the drive pin is during use in a range between ±5° and ±10°, for ex...

Abstract

The invention relates to a skin treatment device (1) comprising a razor handle housing (3), a A detachable brush head (2) and a transmission mechanism (10, 12, 13, 14). The razor handle housing (3) comprises a drive unit for driving at least one drive pin (5) in a rotationally oscillating manner, said drive pin having a first amplitude of oscillation about an axis of oscillation (II), said axis of oscillation being at least substantially perpendicular to the at least one brush head pivot axis (I). The brush head (2) comprises a brush (9) rotatable about a brush axis (III) which is at least substantially perpendicular to the at least one brush head pivot axis (I). The brush (9) comprises at least one driven element (24) coupled to at least one drive pin (5) by means of a transmission mechanism (10, 12, 13, 14), wherein the transmission mechanism (10, 12, 13, 14) will The rotational oscillating motion of the drive pin (5) is converted into a rotational oscillating motion of a driven element (24) having a second amplitude which is smaller than the first amplitude of the drive pin (5).

Description

technical field [0001] The present invention relates to skin treatment devices and more particularly to electrically driven devices comprising brushes for skin treatment, eg for skin cleansing and / or degreasing. Background technique [0002] The use of an electric cosmetic brush for skin treatment is known for example from EP 2 783 595 A1. This known device comprises a housing, a detachable brush head with a brush, and a transmission mechanism interposed between the electric motor and enclosed in the housing and the brush. [0003] While the brushes themselves can be subject to wear and contamination, the more expensive components such as the motor, power supply and / or transmission generally have a longer service life. While many users have several electrically driven devices for skin treatment, including hair removal devices, these devices typically each include a motor, power supply, and / or transmission mechanism in a custom-made design to suit the individual requirements...
