HAIR CLIPPING DEVICE
The present invention relates to a hair clipping device (10) which comprises a housing (14), a cutting assembly (16) including a stationary cutting blade (32) and a moveable cutting blade (34), a drive arrangement (42) for driving the moveable cutting blade (34) relative to the stationary cutting blade (32) in an oscillatory movement along a first axis (40), a comb support element (45) for removably attaching a comb attachment (12) with a plurality of comb teeth (50), and an adjustment unit (58) for adjusting the position of the comb attachment (12) relative to the cutting assembly (16), when the comb attachment (12) is attached to the comb support element (45), wherein the adjustment unit (58) is configured to increase a distance between the comb attachment (12) and the cutting assembly (16) during an extension movement of the adjustment unit (58), and to decrease the distance between the comb attachment (12) and the cutting assembly (16) during a retraction movement of the adjustment unit (58). The hair clipping device (10) further comprises an end stop element (74) which is configured to prevent a movement of the comb attachment (12) towards the cutting assembly (16) during the retraction movement when a minimal distance between the comb attachment (12) and the cutting assembly (16) is reached by contacting the comb support element (45). The end stop element (74) is further configured to cause a coupling of the adjustment unit (58) with one of the stationary cutting blade (32) and the moveable cutting blade (34) if the retraction movement of the adjustment unit (58) is continued after the minimal distance between the comb attachment (12) and the cutting assembly (16) is reached after a contact of the end stop element (74) with the comb support element (45). Said coupling enables an adjustment of the position of the moveable cutting blade (34) relative to the stationary cutting blade (32) along a second axis (56) transverse to the first axis (40) by means of the adjustment unit (58).

The present cleaning device has a compact structure and an aesthetically pleasing shape, rotates steadily, and produces little noise.
Oscillating motor and electric clippers
An oscillating motor and electric clippers. The oscillating motor includes a U-shaped magnetic yoke, four permanent magnets and a swing arm. The U-shaped magnetic yoke causes end faces of two support legs to produce alternating magnetic poles with the control circuit. The four permanent magnets are fixedly mounted to an inner arm via a second magnetic yoke. The four permanent magnets are sequentially distributed on a same circumferential surface having a fulcrum being a centre of rotation. The polarities of radial end faces of the first permanent magnet and the fourth permanent magnet are the same. The polarities of radial end faces of the second permanent magnet and the third permanent magnet are the same, and the opposite of the polarity of the radial end face of the first permanent magnet. When a coil is electrified, the four permanent magnets produce torque having the same direction of rotation.

Flux bridge for pivot motors
A pivot motor has a stator and an armature. The armature has an assembly of two spaced permanent magnets and a triangular flux bridge on one end. Magnetic flux is generated by passing alternating current through an electrical coil in the stator. The flux flows through the permanent magnets to generate electromotive force that vibrates the armature. The triangular flux bridge adjacent the magnets facilitates the flux flow, increasing motor power under typical load conditions and motor efficiency.
