The present invention relates to a cutter system for an electric shaver and/or trimmer, comprising a pair of cooperating cutter blades each having at least one row of comb-like cutting teeth, wherein one of said cutter blades is stationary and the other one is movable relative to the stationary cutter blade along a cutting surface defined between said cooperating cutter blades, said cutting teeth each having pairs of lateral cutting edges tapering towards a tooth tip, wherein said tooth tips of at least one of the cooperating cutter blades are provided with a flattened, beveled tip surface.

A cutting unit having a blade carrier carrying a cutting blade, and a guard. The guard includes a blade-facing surface engaging the cutting blade at a cut location, a planar guard contact surface for contacting the user's skin, where the guard contact surface is angled with respect to the blade-facing surface, and a guard extender separate from the guard. The guard extender includes a planar extension contact surface cooperating with the guard contact surface to provide an extended contact zone across the guard and the guard extender for contacting a user's skin. The blade-facing surface and the guard contact surface converge towards a tip of the guard, such that a cutting direction extends along the guard contact surface towards the tip. The extended contact zone may provide for improved stability and reliable orientation of the cutting unit for cutting while limiting material use.

A blade assembly for a hair cutting apparatus includes a first blade having teeth extending along a first blade edge, and a second blade having teeth extending along a second blade edge. A distance between the first and second blade edges defines a blade gap. A yoke is coupled to the second blade and configured to convert motion of a drive into reciprocation of the second blade relative to the first blade to cut hair. A spring includes a spring base and at least one spring arm configured to reciprocate with the second blade. A guide assembly includes a guide and a spring retainer, the guide being positioned between the first blade and the second blade, and the spring retainer fixing the spring base relative to the first blade, wherein in response to moving the guide relative to the first blade, the blade gap changes.

The trimmer/shaper can be readily gripped by a hand of a user. A neck can accept either a trimmer head or a shaper head or just the shaper head. Both heads include a stationary element and a reciprocating element which moves relative to the stationary element. On the trimmer head the two elements are cutting blades which cut hair that comes between the two cutting blades. For the shaper head, the two elements are non-cutting plates which are sufficiently blunt to substantially not cut hair, but are able to displace hair fibers by vibratory contact from a position where they are initially placed. Hair fibers are placed in a region where a hairline is to be modified. The trimmer head and/or shaper head are then selected to remove unwanted natural hair and/or hair fibers from one side of the hairline, to leave a crisp new hairline.

The present disclosure relates to a smart and novel electronic hair clipper with a digital taper lever. Particularly, the electronic hair clipper includes a housing, a pair of clipper blades disposed on a top portion of the housing, and a digital taper lever disposed along an upper side portion of the housing near the clipper blades for electronically controlling a taper lever height.

A reciprocating razor blade cartridge having fixed blade and fixed blade support, fixed blade is flexible metal sheet, fixed blade support is basin-shaped and supported by basin opening edge, all sides of fixed blade bent downwards and wrapped on outside of basin wall around fixed blade support and make top surface of fixed blade and side surface close to top surface smoothly transition, inner cutting cavity formed between fixed blade and fixed blade support, fixed blade includes hair inlet holes allow body hair enter inner cutting cavity, inner cutting cavity below fixed blade includes movable blade can reciprocate back and forth relative to fixed blade and cut off body hair, movable blade has cutting teeth for cutting body hair corresponding to hair inlet holes, reciprocating razor blade cartridge includes transmission component passes through bottom of fixed blade support to connect movable blade with power device of electric razor.

An adjusting device for adjusting a blade of a hair trimmer where the blade of the hair trimmer has a dynamic cutter blade and a static comb blade. The adjusting device comprises a base, an adjuster pivotably connected to the base, a locator for locating the blade and a biasing means for biasing the blade against the adjuster. The adjuster has a comb-contacting face at a first radial distance from its rotation axis while a cutter-adjusting face is at a second radial distance from the rotation axis, the second radial distance being larger than the first radial distance. By rotating the adjuster, a clearance is created between the cutter blade and the comb blade.
