Abstract

The utility model discloses a permanent magnetic electric cutter, comprising a casing, a cover, an upper blade, a lower blade, an iron core and coils which are connected with the electric power source and controlled by a switch, ferroferrite, a permanent magnetism, a reset spring, a vibration isolation rubber, a vibration-proof block which are inlaid on the centering block, a regulating component which can regulate the range of oscillation, etc. The permanent magnetic electric cutter utilizes the principle that the homopolarity is mutually repellent, and the alternating magnetic field produced by the iron core and the coil which are energized is homopolar with the permanent magnetic field of the permanent magnetism block, which causes the permanent magnetism block to drive the centering block to swing circling the swinging axle. The swinging head and the shift fork cause the upper blade to make reciprocating oscillation corresponding to the lower blade, and thereby, the purpose of shearing is realized. The electric cutter has the advantages of simple structure, light weight, big shearing force, and low noise.

Description

Permanent magnetic electric cutter

The utility model relates to a kind of haircut appliance of hair and beauty.

Along with growth in the living standard, people are more and more higher to the pursuit of U.S., some novel hair and beauty utensils constantly come into the market, and it is more and more superior, haircut appliance only is one of them, and social at present used electric hair cutter all is the old product of the forties, the perhaps improved products that makes improvements slightly on the appearance, but the structure category that does not all break away from unidirectional electromagnet formula, not only complete machine weight is big, the manufacturing cost height, and silicon steel sheet to collide the noise that causes mutually big, be difficult to adapt to the social demand of upgrading day by day.

Task of the present utility model is to improve at the existing in prior technology defective a kind of in light weight, noise is little, shearing force is big permanent-magnet electric hair-clippers of design.

The runout that causes thereby the N that principle of the present utility model is to utilize permanent magnets to produce, S permanent-magnetic field repel with the alternating magnetic field homopolarity that iron-core coil produced realizes that blade makes the purpose that left and right sides reciprocally swinging is sheared.Embodiment is that the oscillating structural member that makes the cutter runout is housed in casing and cover, and this oscillating structural member comprises fixing iron core, coil, and it is electrically connected with power line by connector.Tightly be embedded in the centering block as the magnet steel frame, upper and lower back-moving spring is housed on swinging axle, be slidingly connected with the fixing shift fork of cutter and the swing head of centering block adjacent to permanent magnets, the pure iron piece of iron core, coil.Also be provided with the adjustment means of regulating the blade amplitude, switch etc. in the casing, the bottom knife that forms the relative shear campaign with cutter is fixed on the casing front end.

The utility model is compared with known technology, adopt magneto to replace unidirectional electromagnet formula on the structure, not only simple in structure, in light weight, also because the big inherent characteristic of magnetic field intensity that magnet steel had, therefore not only shear distance is big, and shearing force is big, because the not directly contact of the oscillating structural member in two magnetic fields, so noise is very low, has improved the haircut working environment.

Description of drawings.

Fig. 1 sheds structural representation behind the cover for the utility model.

Fig. 2 is the utility model shape assumption diagram.

Below will be described in further detail according to above-mentioned accompanying drawing embodiment.

From Fig. 1, Fig. 2 as can be known, the casing of permanent-magnet electric hair-clippers (5), cover (25) adopt plastic mould pressing to become the appearance and modeling that the lines flow smoothly.The vibration component that impels cutter (2) runout is housed in casing (5), it comprise be fixed on iron core (9), the coil (8) in the casing (5) and do that reciprocal runout moves by the mutually bonding permanent magnets (7) of two pure iron pieces (16).Iron core (9) forms the mountain font by multi-disc silicon steel sheet closed assembly, middle around coil (8), the lead of drawing on the coil (8) links to each other with the power line that is with protecting pipe (13) (12) by connector (10), and fixing by electric wire pressing plate (14), and switch (15) is connected in the circuit.The permanent magnets (7) of making reciprocal runout is located at iron core (9), the tightly adjacent position of coil (8), be embedded in together in the centering block (6) with the pure iron piece (16) of its two side bonds, this centering block (6) is enclosed within on the swinging axle (21), the upper and lower of centering block (6) is provided with upper and lower back-moving spring (4), (19), both are oppositely arranged, two side bonds of pure iron piece (16) vibrationproof rubber (18), be stained with antivibration pump (17) in the adjacent casing (5), the noise that produces because of bump when avoiding permanent magnets (7) runout.Centering block (6) one that links to each other with swing head (3), swing head (3) is slidingly connected with shift fork (24), and shift fork (24) is fixing with cutter (2), and stage clip (23) is pushed down cutter (2), in order to avoid lift on during runout, the size of thrust is regulated by screw (22).

The size of centering block (6) runout amplitude realizes by the runout adjustment means, and it comprises the following back-moving spring (19) that is located at centering block (6) below and is arranged on adjustment screw (20) composition on casing (5) sidewall.The bottom knife (1) that forms the relative shear campaign with cutter (2) is fixed on casing (5) front end.

The afterbody of casing is equipped with link (11).

After the energising of this electric hair cutter, iron core (9), coil (8) just form alternating magnetic field, owing to close different two closed magnetic circuits that form of it and the magnetic of pure iron piece (16), permanent magnets (7), N, S are repelled mutually because of homopolarity, impelling permanent magnets (7) to drive moves back and forth about centering block (6) is done, do to move back and forth synchronously thereby drive cutter (2),, just form the relation of shearing mutually because bottom knife (1) is fixed by swing head (3), shift fork (24).
