A cosmetic device includes a housing having a handle portion, a head assembly coupled to the handle portion, and a drum assembly within the head assembly. The drum assembly includes a drum having an outer surface configured to abrade the skin or nails of a user during rotation of the drum. The device further includes a electromechanical drive system located within the housing and configured to rotate the drum. The head assembly is configured to rotate about an axis that is substantially perpendicular to the axis of rotation of the drum.

An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.

A five-in-one polishing head includes a blade portion and a handle portion. The blade portion is shaped like a cone having a concave or planar top end. Angle teeth, thin teeth, medium-thin teeth, and thick teeth are sequentially distributed in a conical polishing head according to the tooth density. The angle teeth are located at the top of the conical polishing head in a circle. The thick teeth are located at the end of the blade portion. The center of the end of the blade portion is axially welded and fixed to one end of the handle portion. The conical polishing head is provided with regularly distributed straight lines or oblique lines on a surface from the angle teeth to the thick teeth. The shape of a right-handed groove on the surface is inverted trapezoidal, and the shape of a left-handed groove is triangular.

The actuating nail file assembly includes a housing, a controller, a circuit board, a powertrain, a slider, a head, and a power supply. The assembly is configured to selectively induce actuation of the head in one or more directions. The head is configured to engage a nail of a user, such as fingernail or toenail, and work a surface or edge of the nail to a desired condition. The head may be configured to file the nail by containing an abrasive surface configured to removed portions of the nail. Alternatively, the head may be configured to polish the nail by containing a polishing surface texture. The controller regulates the operation of the powertrain. The powertrain selectively induces radial and linear movement of the head in a plurality of directions so as to repetitively alternate between at least two opposing directions.
