The present disclosure relates to a cutting appliance (10), a blade set (20), and to a cutter (24) and a stationary blade (22) for said blade set (20). Said cutter (24) comprising a main portion (78), particularly a substantially flat main portion obtained from sheet metal material, at least one toothed leading edge (80) protruding from the main portion (78), the at least one toothed leading edge (80) comprising a plurality of teeth (82), and at least one scraping portion (300) comprising a tapered scraper profile (302, 304, 306) at least partially extending in a longitudinal direction (X) that is perpendicular to a cutting motion direction (126) of the cutter (24), wherein the at least one scraping portion (300) is, in a mounted state, arranged to contact a stationary blade (22) of the blade set (20) at a first wall (100) thereof to scrape off accumulated dirt and debris when the cutter (24) and the stationary blade (22) are moved with respect to each other when in operation. The disclosure further relates to corresponding manufacturing methods.

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.

Systems and techniques detecting a reverse current are disclosed. An apparatus comprises a switching circuit coupled to a load and a reference node. The switching circuit may be capable of conducting a reverse current from the reference node to the load when a voltage at the load is lower than a voltage at the reference node. A voltage source has a first terminal coupled to the load, a second terminal configured to follow a voltage at the load, and produces a voltage proportional to a voltage drop across the switching circuit. A comparator circuit is coupled to compare a voltage at the second terminal of the voltage source to the voltage at the reference node and configured to indicate when the reverse current has a magnitude greater than a predetermined threshold.

An electric shaver according to the present disclosure includes: a body block having a holding portion; a head portion having a blade portion and supported on the body block to be swingable about a shaft portion; and a connecting member provided for connecting the body block and the head portion to each other. The connecting member is connected to the body block such that the connecting member is movable relative to the body block in an intersecting direction which intersects with an extending direction of the shaft portion, and the connecting member is also connected to the head portion by way of the shaft portion. The connecting member is connected to the body block by way of a resilient member. With such a configuration, it is possible to provide an electric shaver capable of suppressing the generation of abnormal sounds and vibrations while suppressing lowering of a swing performance.

An electric shaver includes a main body, an outer blade that is held by the main body in a state where a surface of the outer blade is exposed, an inner blade that is disposed inside the outer blade so as to be movable relative to the outer blade, and a rotator that has a rotating body disposed in the main body so as to extend in a moving direction of the inner blade, and a supporter disposed in the main body so as to rotatably support the rotating body. The rotator has an elastic body which enables the rotating body to rotate in a state where the rotating body is in contact with a skin, and which restrains the rotating body from vibrating in a state where the rotating body is not in contact with the skin.

To solve discomfort and safety issues caused by sharp glide sides, a shaving assembly and a hair cutting appliance including the shaving assembly with a protection element is provided. The shaving assembly comprising a supporting member; a cutting element extending in the first direction; a guard foil stretched and extending in the first direction and surrounding the cutting element, the guard foil including a bent part and a flat contact surface, wherein the bent part extends in the first direction for fixing the guard foil on the supporting member, and the flat contact surface is adapted to be in contact with skin; and a protection element arranged at at least one end of the guard foil and including a curved surface exposed to the skin.

There is disclosed a cutting unit (14, 60, 80, 100) for a hair cutting device (10), comprising: a blade carrier (16) carrying a cutting blade; a guard (18) comprising: a blade-facing surface engaging the cutting blade at a cut location; a planar guard contact surface (30) for contacting skin of a user, wherein the guard contact surface (30) is angled with respect to the blade-facing surface; and a guard extender (40, 70, 90) separate from the guard (18), wherein the guard extender (40, 70, 90) comprises a planar extension contact surface (46, 76, 96) configured to cooperate with the guard contact surface (30) to provide an extended contact zone (50) across the guard (18) and the guard extender (40, 70, 90) for contacting skin of a user. The blade-facing surface and the guard contact surface (30) converge towards a tip of the guard, wherein a cutting direction extends along the guard contact surface (30) towards the tip. The guard extender (40, 70, 90) is configured so that the extension contact surface (46, 76, 96) is rearward of the guard contact surface (30) with respect to the cutting direction X. The extension contact surface (96) has a transverse extent along an axis perpendicular to the cutting direction, and wherein there is a gap along the cutting direction X between the guard contact surface and at least a transverse portion of the extension contact surface. The extended contact zone may provide for improved stability and reliable orientation of the cutting unit for cutting while limiting material use.

One embodiment provides a guide comb having a holdable extension including: a central portion including; a plurality of teeth extending at one end thereof; and the holdable extension extending from an opposite end with respect to the plurality of teeth; wherein a lower face of the central portion includes an attachment mechanism to reversibly secure a hair clipper. Other aspects are described and claimed.
