A hair clipper with blade angle adjustment is provided, including a clipper housing defining a longitudinal axis and a cutting end, a clipper bladeset operationally connected to the cutting end and including a stationary blade and a moving blade configured for reciprocating laterally relative to the stationary blade. A cam follower is connected to the bladeset and associated with the clipper housing for rotation about a rotation axis relative to the clipper housing, and a bladeset angle control is associated with the clipper housing. A power transmission is member associated with the clipper housing, connected to the cam follower and constructed and arranged so that user manipulation of the bladeset angle control causes linear movement of the power transmission member and associated angular movement of the bladeset through rotation of the cam follower.

In an electric handheld hair trimmer and method of operating the same, at least one of a first blade and a second blade of a blade assembly is operatively connected to a motor for driven movement in a working direction. A displacement mechanism is operable to selectively displace at least one of the first blade and the second blade independent of operation of the motor. The displacement mechanism includes at least one of an actuator or a separator. The actuator is movable along the longitudinal axis relative to the body and operatively connected to the second blade to selectively move the second blade along the longitudinal axis relative to the first blade independent of operation of the motor. The separator is operable independently of the motor and is positionable between the first blade and the second blade to at least in part separate the first blade from the second blade.

A personal care device, in particular skin treatment device such as electric shaver, including an elongated handle for manually moving the personal care device along a body surface, a working head attached to said handle for effecting a personal care treatment to said body surface, at least one detector for detecting at least one behavioral parameter indicative of a user's behavior when handling the personal care device, and an adjusting mechanism for adjusting at least one working parameter of the working head in response to the detected behavioral parameter.

Electrical hair removal device and method for determining the time behavior of a cyclic motor process during use of the electrical hair removal device with a motor-driven hair cutting unit by measuring the motor current. Parallel to measuring the motor current, the induced voltage of the motor is measured and a timing property of the induced voltage is evaluated, wherein the duration of a time pattern in the induced voltage is analyzed as timing property of the induced voltage. A cutting activity of the electrical hair removal device during use is determined based on the evaluated timing property of the induced voltage, and a force applied onto skin during use of the electrical hair removal device is determined based on the measured motor current and, optionally, on the determined cutting activity.

An electrically operable clipper has a body portion and a head portion, wherein the head portion includes a movable cutter and a fixed comb. The clipper includes an internally located electric motor operable to move the movable cutter. The clipper further includes an operating switch movable between an off position, an operating position and a reset position, wherein the reset position operates a motor reset module of the clipper.

A hair clipper assembly for enhancing the experience of employing a hair clipper includes a hair clipper that has a handle portion and a pair of blades that are movably disposed on the handle portion. The blades are urged to move back and forth when the hair clipper is turned on for cutting hair. An audio unit is integrated into the hair clipper and the audio unit stores a database comprising digital music. The audio unit emits audible sounds from the hair clipper comprising the digital music to entertain a user.

There is disclosed a hair cutting device (10) comprising a cutting unit (30), the cutting unit comprising: a blade carrier (32) carrying a cutting blade (33), the cutting blade comprising cutting teeth (34); a guard blade (40) comprising guard teeth (42); wherein the guard blade is movable along the blade carrier relative to the cutting blade within a guard length range between a first guard position corresponding to a shortest hair cutting length of the cutting unit and a second guard position corresponding to the longest hair cutting length of the cutting unit; and wherein the blade carrier comprises a stop (35) configured to prevent movement of the guard blade past the first guard position and outside of the guard length range, thereby preventing the cutting length from being below the shortest cutting length.

The present invention provides for a hair trimming apparatus having a first precision hair trimmer and a second utility hair trimmer and a switch plate to switch the active mode from the first trimmer to the second trimmer and back to the first trimmer.

Provided is an electronic razor, including: a frame; one or more razor blades detachable from the frame; a razor blade motor to drive the one or more razor blades; one or more sensors; a processor; and a suctioning mechanism positioned below the one or more razor blades, including: a suction fan; a suction fan motor to drive the suction fan; and a hair collection compartment; wherein: the processor learns one or more electronic razor settings based on usage history of the electronic razor. Included is a method for determining one or more electronic razor settings of an electronic razor, including: learning, by a processor of the electronic razor, the one or more electronic razor settings based on a usage history of the electronic razor.
