Device for treating skin
First Claim
1. A device for treating skin comprising:
- a housing;
a shaft located in the housing having a longitudinal axis ‘
A’ and
an end for receiving a skin treating part; and
a drive means coupled to the shaft for (i) rotating the shaft about its longitudinal axis, and (ii) oscillating the shaft in a direction along the longitudinal axis, wherein the drive means comprises (i) a rotational drive unit that includes a motor having a motor shaft rotatably coupled to a gear that is mounted to a cut-out portion of the shaft and configured to rotate the shaft about the longitudinal axis and (ii) an oscillation generator configured to oscillate the shaft, via a transfer of axial force through at least one support member to the shaft, along the longitudinal axis, wherein the oscillation generator is located about the shaft and configured to enable the shaft to rotate relative to the oscillation generator, further wherein the oscillation generator comprises (i) a solenoid and (ii) a flux assembly that includes at least a flux concentrator and magnet, wherein the flux assembly is moveable along the longitudinal axis of the shaft, via a bushing about the shaft, relative to the solenoid.

Abstract
The present application relates to a device for treating skin (1) comprising a housing (2), a shaft (14) located in the housing (2) having a longitudinal axis (‘A’) and an end for receiving a skin treating part (3). The device (1) further comprises a drive means configured to cause the shaft to rotate about its longitudinal axis, and to oscillate in a direction along the longitudinal axis, wherein the drive means comprise a rotational drive unit for rotating the shaft (14) and an oscillation generator (26) for oscillating the shaft. The oscillation generator (26) is located about the shaft (14) such that the shaft is rotatable relative to the oscillation generator. Furthermore, the oscillation generator (26) comprises a solenoid (39) and a flux assembly (25), and the flux assembly (25) is moveable along the shaft (14) relative to the solenoid (39).
