An electric-powered trimmer includes a handle. A battery pack is positioned in the handle. An electrical circuit is positioned in the handle and electrically connected with the battery pack. A cutting assembly is removeably coupled to the handle.

The present disclosure relates to a limiting comb extension and retraction structure of hair scissors, including a limiting comb and an adjusting assembly which are arranged on a body of the hair scissors; the adjusting assembly includes an adjusting rotary knob and an adjusting shell; the adjusting rotary knob is horizontally placed on the body of the hair scissors; the adjusting shell is slidably arranged in the body of the hair scissors and slides synchronously with the limiting comb; a double-helix-group structure is arranged between the adjusting rotary knob and the adjusting shell; each helix group includes a boss and a spiral groove section which cooperate with each other; the boss is located on the adjusting shell; the spiral groove section is located on the adjusting rotary knob; the respective bosses are located on rotating trajectories of the corresponding spiral groove sections.

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 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.

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.

A hair clipper or cutter is provided with an adjustment slider that adjusts the gap between an inner and outer blade. A yoke is attached to the inner blade. The adjustment slider may be configured with preset gap lengths and may be adjustable before, after, or during a hair cutting operation. A T-guide couples the adjustment slider to the inner blade to slidably move the inner blade relative to the outer blade. The yoke, inner blade, outer blade and/or T-guide may be magnetized to create an attractive or repulsive force between the inner blade and the outer blade. In some embodiments, the yoke is not metallic. The magnetized yoke may be a non-conductive magnet carrier (e.g., plastic) or conductive material (e.g., ferromagnetic).

A haircutter handle has upper and lower housings. The upper housing and lower housing join to form a circumvoluted and/or spiraled exterior surface. The handle narrows and extends axially from a blade end to a handle or gripping end. The blade has an upper blade that oscillates over the lower blade to cut hair. The handle has a reduction taper that facilitates gripping and/or handling the handle. The taper also orients the motor and battery so that the center of gravity is positioned within the palm of the user's hand when gripping the handle. The blade end of the handle has a width and/or height that are greater than a width and/or height at the handle end. The reduction in height and/or width dimensions define a taper. In some embodiments, the width tapers more than the height tapers to facilitate gripping the handle about the center of gravity.

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.

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 clipper preferably also uses a self-contained motor-driven pivotable adjustment mechanism to adjust the relative position of the stationary and reciprocating blades of a common type of blade set. One or more on/off switches operable by the thumb of the hand holding the clipper to afford a barber total automatic adjustment with the clipper itself in an on or off condition.

An electric hair-cutting device that has a housing. Further, the electric hair-cutting device has a hair-cutting module coupled to a first end of the housing, the hair-cutting module comprising blades and configured for cutting hair. Also, the electric hair-cutting device has a plurality of pinholes on a top of the housing and adjacent the hair-cutting module for delivering air to the hair-cutting module to cool the hair-cutting blades and a cooling module contained in the housing, the cooling module that has a fan and receives air through a plurality of pinholes on a bottom end of the housing and delivers the air to the plurality of pinholes adjacent the hair-cutting module thereby cooling the hair-cutting module.
