A method for assembling a hair cutting appliance is presented. A body is provided with a power switch connected to a power source. A drive system within the body is in selective electrical communication with the power source. A cutting unit is electrically connected to the drive system. An optical sensor is mounted to the body to sense a pre-defined skin-hair edge. A control circuit within the body is electrically connected to the optical sensor. A switching element is electrically connected with the control unit. The switching element is switchable by the control circuit between a conducting state and a non-conducting state. The switching element is switched to the non-conducting state when a sensed condition of the optical sensor exceeds a first pre-programed threshold. The first pre-programmed threshold is stored in the control circuit. A method is provided for assembling a power transform module used with a hair cutting appliance.

The disclosure provides a personal care trimmer having an ultrathin fixed blade and a manufacturing method for an ultrathin fixed blade. The personal care trimmer comprises a body and a cutting head. The cutting head comprises a fixed blade and a movable blade, the fixed blade being fixed, the movable blade being driven by a drive device in the body to perform left-right reciprocating motion along the fixed blade to form a shearing surface. The fixed blade is an ultrathin fixed blade, and a blade body part, outside blade teeth, of the fixed blade is fixed with a blade supporting piece, such that the fixed blade is supported by the blade supporting piece so as not to deform. In the disclosure, an ultrathin fixed blade is adopted to be capable of trimming long hair in place once, the trimming position and length are more accurate, and the operation is easier.

A shaver, a shaver cutting mesh, and a process for manufacturing the shaver cutting mesh. The process for manufacturing the shaver cutting mesh does not adopt an integral drawing process, but divides the cutting mesh into two parts to be machined, and then completely combines the two parts together by adopting a welding process, so that the mesh surface part is good in uniformity, the radian of the whole mesh surface also can be ensured, the comfort degree and the cleanness in shaving are further improved, and the housing part is machined at a larger thickness (such as 0.5 mm) than that of the mesh surface part to ensure the strength of a whole mesh cover.

The present invention relates to a hair cutting appliance (10) and to a blade set (20) for a hair cutting appliance (10). Said blade set (20) comprises a stationary blade (22) comprising a first wall portion (100) and a second wall portion (102) that define therebetween a guide slot (96), a movable cutter blade (24) received at the guide slot (96), and a transmitting member (70) configured to be engaged by a driving member, wherein the transmitting member (70) is further configured to actuate the movable cutter blade (24) relative to the stationary blade (22), wherein the movable cutter blade (24) is laterally inserted into the guide slot (96), wherein the transmitting member (70) is fed to the stationary blade (22) in a feed direction (190) that is different from an insertion direction (188) of the movable cutter blade (24), and wherein the transmitting member (70) is coupled to the movable cutter blade (24), particularly to a main portion (78) thereof, such that the movable cutter blade (24) is secured at the stationary blade (22), particularly undetachably retained. The disclosure further relates to a method for manufacturing a respective blade (22).

The present invention relates a method of manufacturing a hair cutting device with an outer metal shell, comprising the steps of forming the outer metal shell into a desired shape and mounting functional components for performing or helping to perform a personal care treatment into and/or onto said formed outer metal shell. Said forming the outer metal shell includes a hydraulic pressure forming step.

The present invention relates to a cutter system for an electric shaver and/or trimmer, comprising a pair of comb-like cutting elements each with at least one row of cutting teeth and movable relative to each other, wherein one of said cutting elements has thickened and/or rounded tooth tips overhanging the tooth tips of the other cutting element, characterized in that said overhanging tooth tips are provided with a two-step rounding including a spherical or drop-shaped or pearl-shaped thickening and a bent or curved portion connecting said thickening to a main tooth portion and bent away from the skin contact surface of said main tooth portion, wherein a concave depression is formed in the transitional section between said thickening and said bent or curved portion on the skin contact side of the teeth.

A hair cutting appliance, a blade set for a hair cutting appliance, an integrally formed metal-plastic composite stationary blade for said blade set, and a method of manufacture are described. A stationary blade includes a first wall portion arranged to serve as a skin facing wall when in operation, and a second wall portion at least partially offset from the first wall portion, such that the first wall portion and the second wall portion define therebetween an inner guide slot arranged to receive a moveable cutter blade. At least one toothed leading edge is jointly formed by the first wall portion and the second wall portion, and a plastic component comprising at least one mounting element.
