Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an electric hair clipper, and particularly to an electric hair clipper equipped with a plowing member.

[Background of the invention]

In a conventional electric hair clipper equipped with a plow cutting plate, the positions of the hair introducing portion and the hair introduction preventing portion of the plow cutting plate remain unchanged with respect to the cutting edge of the blade body (fixed blade and movable blade) during plow cutting. Therefore, when you shave the electric hair clipper from top to bottom along the hair on your head, the hair in the area facing the hair introduction part of the hair clipping board is cut into strips, leaving a large amount of hair in one area. As a result, it is not possible to mow with a uniform plow with an effect of blurring.

[Purpose of the invention]

The purpose of the present invention is to eliminate such drawbacks of the prior art,
To provide an electric clipper capable of uniform plow cutting and having a combing effect.

[Summary of the invention]

In order to achieve this goal, the present invention provides an electric hair clipper equipped with a plow-cutting member, in which the positions of the hair introduction part and the hair introduction-blocking part of the plow-cutting member are interlinked with the reciprocating direction of the movable blade during plowing. It is characterized by being configured so that it can reciprocate in the direction.

[Embodiments of the invention]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the main parts of an electric hair clipper according to an embodiment of the present invention, FIG. 2 is a cutaway side view of the main parts of the electric hair clipper, and FIG. 3 shows the moving state of the plow board in the electric hair clipper. It is a partially enlarged plan view.

A first bevel gear 3 is attached to the middle of the rotating shaft 2 of the motor 1, and an eccentric cam 4 is fixed to the tip of the first bevel gear 3. It is fitted into the groove 7. The drive member 6 is molded from a flexible synthetic resin, and as shown in FIG. 1, it has a substantially U-shaped planar shape, and both side walls are thin and the tips thereof are fixed. The central portion of the drive member 6 is movable. A driving rod 8 is integrally formed on the front surface of this central portion, and its tip fits into a driving plate 9.

The driving plate 9 is connected to a movable blade 11 that is pressed against a fixed blade 10, and the fixed blade 10 is fixed to a holder 12 (see FIG. 2).

Therefore, the rotation of the motor l is controlled by the eccentric cam 4 and the drive member 6.
The movable blade 11 is converted into a reciprocating motion by the action of the drive rod 8 and the drive plate 9, and the movable blade 11 reciprocates at high speed.

A second bevel gear 13 that meshes with the first bevel gear 3 during plowing is disposed near the first bevel gear 3;
is connected to an eccentric cam 15 via a speed reduction means 14 consisting of a gear group (not shown).

An eccentric pin 16 protruding from the eccentric cam 15 is fitted into an elongated hole 18 (see FIG. 1) formed at the rear of the plow board 17. This long length 18 extends substantially parallel to the reciprocating direction of the movable blade 11. A guide groove 19 (see FIG. 1) extending in a direction substantially perpendicular to the longitudinal direction of the elongated hole 18 is formed on both sides of the middle part of the plow cutting plate 17, and a pin 21 hanging down from the inner surface of the upper case 20 is inserted into each of the guide grooves 19 (see FIG. 1). It is inserted into the guide groove 19. Hair introduction prevention portions 22 and notched hair introduction portions 23 are alternately formed along the width direction at the tip of the plow board 17, and the planar shape is convex.

Arms 24 protrude from both sides of a box (not shown) that accommodates the deceleration means 14, and a knob 25 is attached to the tip of each arm.

The arm 24 passes through a slide groove 26 formed in the upper case 20, and the knobs 25 are exposed from both sides of the upper case 20. The plowing position and the non-plowing position of the knob 25 are maintained with moderation.

When not mowing, the knob 25 is moved to the rear (towards the motor 1), so the second bevel gear 13 is separated from the first bevel gear 3 as shown in FIG. The force is not transmitted to the plow board 17,
7 is in the standby position on the plow cutting board.

When mowing, the knob 25 is slid forward (towards the vA moving member 6). Then plow cutting board 1
7 moves forward together with the second bevel gear 13 and the speed reduction means 14, and the tip of the plowing plate 17 (bristle introduction prevention section 229, hair introduction section 23) faces the cutting edge of the movable blade 11. With this movement, the second bevel gear 13 meshes with the first bevel gear 3, and the rotational driving force of the motor 1 is transferred to the first bevel gear 3. Second bevel gear 13
It is also transmitted to the eccentric cam 15 via the deceleration means 14. Since the eccentric pin 16 provided on the eccentric cam 15 is inserted into the elongated hole 18 of the plowing plate 17, as the eccentric cam 15 rotates, the plowing plate 17 moves toward the movable blade 11 as shown in FIG. It reciprocates in the Y direction that is orthogonal to the reciprocating direction X. Hair introduction prevention part 2 drawn with a solid line in this figure
2 and the position of the hair introduction part 23 indicate the position where the plowing plate 17 is the most retreated, and in this state, the hair introduction part 23
Movable blade 1 in which only the bristles introduced from the blade move back and forth at high speed.
1 and a fixed blade 10.

Further, the positions of the hair introduction prevention part 22 and the hair introduction part 23 drawn by the dashed lines indicate the position where the plow cutting plate 17 is most advanced.
In addition, since it protrudes beyond the cutting edge of the movable blade 11, hair is not cut even when the movable blade 11 moves back and forth.

Appropriately, the reciprocating movement of the plow cutting plate 17 is about 100 to 180 times per minute, and if the movable blade 11 reciprocates many times per unit time, it is not preferable because the mowing will not be carried out efficiently.

In the embodiment described above, a single motor is used to reciprocate the movable blade and the plowing plate, but in this case, a speed reduction means is required for the reasons mentioned above. Therefore, for example, a dedicated drive source consisting of a pulse generator and an electromagnet operated based on pulse signals from the pulse generator is provided, thereby making it possible to reciprocate the plow board at a desired speed.

FIG. 4 is a perspective view showing a modification of the plow cutting board 17. In the case of this example, flexible legs 27 extending substantially parallel to the elongated holes 18 are formed at the front and rear positions of the plow cutting board 17 where the elongated holes 18 are formed. A through hole 28 is provided overlappingly at the tip. A knob 25 is arranged above the plow cutting board 17, and two pins 29 superimposed on the lower surface of the knob 25 are inserted into the through holes 28 of the legs 27.
The plow cutter plate 17 and the knob 25 are connected by fitting into the upper case 20 (the knob 25 is not shown).
It is slidably exposed on the top surface of the

Since the other structures are almost the same as those of the previous embodiment,
Their explanation will be omitted.

When not plowing, the knob 25 is moved rearward, so that the plow cutting board 17 remains stationary as in the previous embodiment. When the knob 25 is moved forward to perform plow cutting, the first bevel gear 3 and the second bevel gear 13 mesh with each other, thereby causing the plow cutting plate 17 to reciprocate in the front-rear direction at a predetermined speed. At this time, the knob 25 is in the plowing position and held with moderation, and since the reciprocating movement of the plow cutting board 17 is absorbed by the flexible legs 27, the knob 25 does not shake during plowing. can be prevented. This structure is also simpler and easier to assemble than those of the previous embodiments.

FIGS. 5(a) and 5(b) are explanatory diagrams showing further modified examples of the plow cutting board 17. In this example, the plow board 17
The hair introduction portion 23 formed in the hair introduction prevention portion 22 is divided into an intermediate groove 23a with a relatively shallow cut and a deep groove 23b with a relatively deep cut, as shown in the figure. Intermediate groove 23
a and deep grooves 23b are alternately and repeatedly provided.

When the plow cutting board 17 is at the most forward position as shown in FIG.
On the other hand, when the plow cutting plate 17 is at the rearmost position as shown in FIG. The reciprocating stroke S of the plate 17 is determined.

Therefore, in the state shown in FIG. 5(a), only the hair introduced into each deep groove 23b is clipped, while in the state shown in FIG. 5(b), the hair introduced into each intermediate groove 23a and deep groove 23b is clipped. , there is a difference in the foot of the hair clipping in the former case and the latter case. By making changes in this way, it is possible to perform blurred cutting.

Although the above embodiment describes the case where the plow cutting board reciprocates in a linear direction, the present invention is not limited to this. For example, the plow cutting board may move in an elliptical or circular motion to prevent the introduction of hair. It is also possible to reciprocate the position of the part and the bristles introducing part in a direction that substantially interlinks with the reciprocating direction of the movable blade.

〔Effect of the invention〕

The present invention has the above-mentioned configuration, and by reciprocating the plow-cutting member in a direction interlinked with the reciprocating direction of the movable blade during plow-cutting, it is possible to cut even the hair that has been guided to the hair introduction part of the plow-cutting member. You can create times when you can do it and times when you can't. Therefore, mowing is performed intermittently, suppressing localized over-cutting unlike conventional methods, and achieving uniform mowing. Further, the reciprocating motion of the combing member in the front-back direction loosens the uneven hair, exerts a combing effect, and allows for a clean combing.
