An electric shaver, comprising an elongated housing receiving an electric motor and/or an electric power source, a working head attached to said housing, wherein said housing includes an elongated base element and a cover element closing said base element and surrounding a connection connecting said electric motor and/or said electric power source to said working head, wherein said cover element is sealed to said base element and/or to said connection by at least one seal.

A wet shaving device comprising a motor; an actuator configured to vary the speed of the motor; a rotary blade module having at least one cutting element; and a drive train assembly including at least one shaft operatively coupling the motor and the rotary blade module, wherein the at least one shaft may be configured to transfer the rotational movement of the motor to the rotary blade module.

A manually operated hair trimming device having a barrel which is rolled over hair to be trimmed. The barrel has at least one aperture through which hair is able to protrude. The device has a first cutting blade provided inside the barrel and a second cutting blade is associated with the barrel. In use, as the barrel is rolled over hair to be trimmed, hair protrudes through the at least one aperture and is cut by a shearing force between relatively moving first and second cutting blades.

A shaving apparatus (1000) includes a rotary cutter (220) comprising a cutter tube, the rotary cutter comprising a plurality of closed-geometry apertures (221) in an outer surface of the cutter tube, each of the closed-geometry apertures extending along an aperture axis and comprising: a cutting edge (222); a first section having a first width measured transverse to the aperture axis; a second section having a second width measured transverse to the aperture axis; a waist section having a third width measured transverse to the aperture axis, the waist section located between the first and second sections; and the third width being less than each of the first and second widths; a blade (211) having a cutting edge, the blade mounted adjacent the rotary cutter; and an electric motor (130) operably coupled to a power source and the rotary cutter to rotate the rotary cutter about a rotational axis of the rotary cutter so that a user's hairs are sheared between the cutting edge of the blade and the cutting edges of the cutter.

A portable electric rotary slicer, which may have a handle, a blade holder configured to hold a blade assembly, and a pusher. The blade assembly may couple to the blade holder by a ring gear configured to fit concentrically around the blade assembly, allowing the rotary slicer to be operated at a high torque with relatively little electrical power being supplied. The rotary slicer may have a stand, a safety cylinder disposed around the blade assembly and configured to protect the user's fingers when pushing material into the blade assembly, and a divider disposed within the safety cylinder. To operate the device, a user may insert a blade assembly into the blade holder, place material directly above the blade assembly and under the pusher, activate the switch of the rotary slicer, and press downward with the pusher to force the material into the spinning blade of the blade assembly.

A multi-cutting element shaving device is disclosed. The device comprises a handle and a head portion comprising at least two cutting assemblies, which are mounted in parallel, to one another on a frame of the head portion. The cutting assemblies include each a cylindrical screen and a blade housed in the cylindrical screen. Each of said cylindrical screens is rotatable about a respective longitudinal symmetry axis thereof, and the rotation of each cylindrical screens is manually effected by translating the head portion along a surface with the cylindrical screen contacting the surface so that substantially no sliding, of the cylindrical screens occurs as the head portion is translated against the surface. The head portion mounting angle relative to the handle is changeable during use of the shaving device such that both cylindrical screens are simultaneously maintained in contact with the surface, which is being shaved.

The present disclosure generally relates to instruments for neurotologic surgical procedures, and more particularly, instruments for shearing ear canal hairs having combined shearing, illumination, and vacuum functions. In certain embodiments, the instruments may further facilitate visualization of the ear canal during the shearing of ear canal hairs.
