A flex clipper provides a feature to help the cutting blade set float more effortlessly by adjusting automatically to the contours of a client's head to prevent getting stuck and causing cuts and irritation to the scalp. The hair clippers preferably also uses a self-contained motor-driven adjustment mechanism to adjust the relative position of the stationary and reciprocating blades of a common type of blade set. Two momentary switches operable by the thumb of the hand holding the clipper afford a barber total automatic adjustment with the clipper itself in an on or off condition.

The invention relates to an electrically driven device, for example an electric hair removal device, such as a wet or dry shaver, an electric toothbrush or an electric skin treatment device. The electrically driven device comprises a housing having a chassis, wherein the chassis comprises an electric motor having a first drive shaft, a battery unit, and an oscillating body having a second drive shaft. A first longitudinal axis is defined arranged along the second drive shaft, a second longitudinal axis is defined arranged along the first drive shaft, and a third longitudinal axis is defined arranged through the center of the body of the battery unit, wherein the second longitudinal axis and/or the third longitudinal axis are parallel offset to the first longitudinal axis.

A beard trimmer includes a handle having a motor, a cutting head having a fixed blade and a movable blade, and a cutting head suspension system. The suspension system includes a fixed-blade movable support connecting the fixed blade of the cutting head to the handle. The fixed-blade movable support is pivotably mounted on the handle and has a proximal portion located on the handle side and a distal portion located on the cutting-head side. An elastic means creates a return force that allows the fixed-blade movable support to return to its rest position and the pressure of the cutting head on the user's skin to be absorbed. The handle includes a hollow space to accommodate the proximal portion of the movable support, the proximal portion of the movable support being fully retractable into the hollow space in the handle when the elastic means is in the rest position.

A clipper head (100) includes a base surface (102) and a front surface (204). One or more clipper teeth (109) extend from an intersection (108) of the base surface and the front surface. One or more protuberances (110,111,112) extend from the base surface. The protuberances reduce the surface area that contacts a patient's skin, thereby reducing friction and drag.

A concaved cutter head assembly for hair trimmer comprising a fixed blade, a movable blade and a slot support fixed to the fixed blade; the fixed blade and the movable blade comprise a fixed blade toothed edge and a movable blade toothed edge respectively; the movable blade toothed edge is driven to move reciprocally along slots on the slot support with respect to the fixed blade toothed edge to form a cutting surface; a fixed blade seat is also provided, whereas one end of which is provided with a protective cover; a frontal edge of the protective cover is positioned in front of the fixed blade toothed edge; the fixed blade toothed edge, the movable blade toothed edge, the slots and the frontal edge of the protective cover are all concave arcs, and all these concave arcs are concentric with respect to one another.

There is provided an electric shaver having (a) a main body that includes a shaver head and a first pair of contacts through which a first voltage is provided, and (b) a cap that is installable on the main body in a first orientation or a second orientation, and when installed on the main body covers the shaver head. The cap has (1) a second pair of contacts that engage the first pair of contacts when the cap is installed on the main body, to receive the first voltage, and (2) a circuit having (i) a diode bridge that receives the first voltage via the second pair of contacts, and provides a second voltage of proper polarity for utilization by other components of the circuit, and (ii) an ultraviolet (UV) light source that utilizes the second voltage, and when ON, emits UV light that irradiates the shaver head.

A shaving head for an electric dry shaver includes a base element for carrying at least three cutter units. Each unit provides an outer cutter and an inner cutter arranged to be moved in sliding contact relative to each other. At least one cutter unit includes a foil-type outer cutter. The shaving head further includes a first trimmer-type cutting unit that has a plurality of slots defined by a plurality of adjacent bar elements featuring cutting edges. The shaving head also includes a second trimmer-type cutting unit having an outer cutter that includes a plurality of teeth featuring cutting edges and spaced apart from each other so as to define a plurality of slits.

A smart personal grooming device or otherwise cutting device comprises a body with a handle, a head portion, a hair cutting implement, and a camera oriented toward the hair cutting implement. The camera captures images of a skin area and a hair area of a user and a processor detects, based the images, each of the skin area and the hair area. A boundary is defined between the skin area and the hair area. The processor determines a control state based on the boundary that causes the processor to implement one or more algorithms controlling an operating or feature of the smart personal grooming device or otherwise cutting device, including, for example, activating the cutting implement to cause the cutting implement to remove hair in a hair area of the user.
