Abstract

The utility model discloses motor driving hair clippers with large shearing force and low power consumption. The motor driving hair clippers uses a fixed supporting point shaft on which two springs and a push rod are penetrated, a sliding blade is positioned and are pressed on a fixed blade by the front extending short arm of the push rod, then the motor driving hair clippers uses a motor to drive an eccentric gear mechanism to drive the push rod, after the force of the motor is amplified through a lever principle type pushing mechanism, the sliding blade is driven by the force of the motor so that the sliding blade does arc linear oscillation on the fixed blade, and then the motor driving hair clippers shears hair.

Description

Motor driving hair clippers

The utility model relates to a kind of electric hair cutter of the usefulness of getting a haircut.

The hair electric cutter that present people generally use is cut, all be to adopt electromagnetic viscosimeter formula structure, driving sliding blade by the electromagnetic viscosimeter body moves reciprocatingly on fixed blade and cuts off hair, eddy current effect that not enough is in the electromagnetic viscosimeter iron-core coil and cross section bump temperature rise are fast, can not continuous operation (electromagnetic viscosimeter formula electric hair cutter operation instructions general provision can only use 10 minutes at every turn continuously), and service behaviour shakiness, need often to regulate repeatedly, the more important thing is the scarce limit that the electromagnetic vibrator reactive loss is big.

The purpose of this utility model is thoroughly to improve above-mentioned the deficiencies in the prior art, and provides a kind of simple in structure, but big, the low in energy consumption long time continuous working of shearing, safe and reliable motor-driven hair clipper.

The purpose of this utility model is achieved through the following technical solutions.With being installed with spring (7) above the fixed pivot axle (1), (8) and catch bar (2) and the front end (11a) that is fixed in shell (11) locate, the galianconism convex point (2a) that protracts of catch bar (2) inserts in the oblong aperture (5a) of sliding blade (5) central authorities, sliding blade (5) is located and is pressed on the fixed blade (6), a motor (4) is arranged in shell (11), on the axle core shift wheel apparatus (3) is housed, core shift wheel apparatus (3) vertically is sandwiched in the U type groove (2b) of catch bar (2) afterbody then, is used to drive catch bar (2) drive sliding blade (5) and on fixed blade (6), does the camber line swing and cut off hair.

The utility model compared with prior art has simple in structure, uses the lever type pushing mechanism, and its clipper power is increased; Adopt motor to replace hertz oscilltor, make it low in energy consumption, noise is little, performance is steady; Need not regulate, but chuck is not sent out, and long time continuous working, can not crossed temperature height of a specified duration because of continuous operation, burn coil and damage.Catch bar adopts plastics to make, and has good insulating properties, and is safer reliable.

The utility model is described in further detail below in conjunction with accompanying drawing, and fixed blade (6) is that a square shaped steel plate is made, and front end has a row and cuts tooth, and the centre has a groove (6a), and its afterbody is drilled with two fixedly screws of usefulness (6b).Sliding blade (5) also is that a square shaped steel plate is made, and there is a groove (5b) centre, and central part has an oblong aperture (5a), and the upper end has and the corresponding tooth of cutting of fixed blade.Catch bar (2) is to adopt a kind of plastics with certain intensity to be pressed into, leading section bends downwards, front tip part is made convex point (2a), be used for inserting the oblong aperture (5a) of sliding blade (5) central authorities, middle front part is drilled with a circular hole (2c), be used to penetrate fixed pivot axle (1), its afterbody has a U type groove (2b).Fixed pivot axle (1) is that a long bolt is made, and the front end (11a) that is fixed in shell (11) is located, and is installed with spring (7), (8) and catch bar (2) above, and top tip part has nut (1a) to tighten.Spring (7), (8), catch bar (2) is held in the middle of, make the galianconism convex point (2a) that protracts of catch bar (2) keep working clearance and pressure between sliding blade (5) and the fixed blade (6) automatically.Motor core shift wheel apparatus (3) is made of a Z profile shaft (3a) and bearing (3b), Z profile shaft (3a ') end is fixed on the axle of motor (4), (3a ") puts a bearing (3b) and has formed core shift wheel apparatus (3) other end, core shift wheel apparatus (3) vertically is sandwiched in the U type groove (2b) of catch bar (2) afterbody.After motor (4) energising, it is the center of circle with fixed pivot axle (1) that core shift wheel apparatus (3) driving catch bar (2) makes it, and the long-armed length in back is done the camber line swing for radius.Because core shift wheel apparatus (3) is vertically to be sandwiched in the U type groove (2b), do not limited to when core shift axle and fixed pivot axle fore-and-aft direction shift transformation, and the power of motor (4) is shouldered rod principle formula pushing mechanism by this and has been carried out amplification and then driven sliding blade (5) by the galianconism convex point (2a) that protracts, its sliding blade (5) is gone up at fixed blade (6) followed tail end to do rightabout camber line swing, reach and cut off the hair purpose.

Above-mentioned eccentric wheel apparatus also can adopt an oblate column type circle wheel among the embodiment, and an eccentric orfice is bored in the circle wheel center of circle relatively, and motor shaft directly is through at and is fixed in the eccentric orfice position, and the circle wheel is sandwiched in the U type groove (2b).

Advantage of the present utility model:

1. be easy on the production equipment basis of prior art realize.

2. application of motor has replaced hertz oscilltor and makes its electric power factor rise to 0.8 from 0.4, greatly reduces reactive loss, has good power savings. Adopt lever principle type pushing mechanism in addition, reduced the wattage of motor apolegamy power, this is again an energy-conservation factor, thus the utility model or a kind of effective energy-conserving product.

3. sliding blade (5) is the center of circle with fixed pivot axle (1), the length of galianconism of protracting is that radius is done the camber line swing on fixed blade (6), make every pair of bottom knife cut tooth and close up from the rear end to paracone, moving reciprocatingly than sliding blade makes that to cut tooth up and down parallel laborsaving to pressing from both sides.

4. use Z profile shaft and bearing and do the core shift wheel apparatus, reduced noise, reduced the running frictional resistance.Make its U type groove contact-making surface not easy to wear, on structural design and use material, also considered durability and reliability emphatically in addition.Guaranteed that any parts generally need not be changed and motor carbon etc.

5. applied spring keeps working clearance and the pressure between sliding blade and the fixed blade automatically, need not regulate, and work efficiency can have been improved by long time continuous working in the save trouble and labor in addition greatly.

6. push rod (2) is the existing good insulating properties made from a kind of plastics, has definitely guaranteed safe in utilization.
