Description

[Detailed Description of the Invention] This invention relates to an improvement of an electric hair clipper, and its purpose is to automatically brush away the hair that accumulates on the tip of the electric hair clipper when the electric hair clipper is used.

Conventionally, when cutting hair with an electric hair clipper, hair debris accumulates on the tip of the clipper, making the cutting edge invisible and making it difficult to know the exact direction in which the cutting edge is moving and the cutting situation. For this reason, it is necessary to frequently remove the hair clippers from the head and shake out the hair from the tips, which is a hassle and also causes hair clipping.

Focusing on this fact, this invention utilizes an electric hair clipper equipped with a plow comb and adds vibration to the plow comb, thereby automating hair removal and constantly visualizing the direction in which the cutting edge is moving. To provide an electric hair clipper which is easy to shave, and which reduces the number of hair removal operations to easily, quickly and efficiently cut hair.

The details will be explained below based on the drawings. The drawing illustrates an electric hair clipper according to this invention.
The main body case 1 consists of upper and lower plastic cases 1a and 1b that are split into two halves, and inside the lower case 1b, in order from the tip, there is a clipper-type reaping device 2, a plastic vibrator 3 that drives it, and a motor 4. The storage battery 5 is equipped with a storage battery 5, and an upper case 1a is screwed onto the storage battery 5, so that it has a long box-like structure.

The vibrator 3 includes a thick rear wall 3a fixed to the lower case 1b, and a thick front wall 3 having an interlocking arm 3d protruding forward and connected to the movable blade 2b of the reaping device 2.
b are connected by thin left and right side walls 3c and 3c to form a parallelogram in plan view, and the crank pin 8 is engaged with a vertically long long groove 7 formed on the rear surface of the front wall 3b. By rotating the front wall 3b at high speed with the motor 4, the front wall 3b vibrates back and forth in the left and right directions through the rocking elastic deformation of the left and right side walls 3c.

The reaping device 2 includes a fixed blade 2 mounted on a fixed blade support 10 that is removably pivoted to a support shaft 9 on the lower case 1b.

The fixed blade 2a and the movable blade 2b are pressed and biased so as to be slidable, and the respective cutting edges of the fixed blade 2a and the movable blade 2b protrude from the tips of the upper and lower cases 1a and 1b. The interlocking arm 3 of the vibrator 3 is attached to the protrusion 14 protruding from the upper surface of the movable blade support 11.
By engaging the engagement hole 15 at the tip of d, the horizontal vibration of the vibrator 3 is linked to the movable blade 2b.

An operation knob 17 for a slide switch for stopping the motor drive is attached to the knob guide hole 16 opened on the side surface of the main body case 1 so as to be slidable in the front and back direction, and a plow comb operation knob is provided below the operation knob 17. 18 is mounted so as to be movable in the vertical and longitudinal directions. A comb holder 19 is connected from the comb operating knob 18 toward the inside of the main case 1, and the plowing comb 20 attached to the comb holder 19 moves between the movable blade 2b and the tip of the upper case 1a as the operating knob is operated. It is equipped to move forward and backward through the gap. And switch operation knob 17
is moved to the rear end of the knob guide hole 16 in the off position, the comb operation knob 18 is pushed upward into the notch 21 formed at the lower edge of the knob 17, and then the comb operation knob 18 is moved to the rear end of the knob guide hole 16. When the switch operation knob 17 is moved forward to the ON position while the knob 18 is kept engaged, the plow comb 20 protrudes forward from the gap between the movable blade 2b and the tip of the upper case 1a, and at the same time, Drive of the reaping device 2, i.e. movable blade 2
b starts to vibrate left and right. When the switch operation knob 17 is returned to the rear off position, the plowing comb 20 retreats into the gap, and the comb operation knob 18 is automatically turned off by the force of a spring 22 attached to the comb holder 19. 17 and returns to the lower edge notch 23 of the knob guide hole 16. In the case of round mowing, by moving only the switch operation knob back and forth, the reaping device 2 is driven and stopped while the plow comb 20 remains in the backward position. Incidentally, when mowing the plow, move the plow comb 20 forward from the gap between the movable blade 2b and the tip of the upper case 1a to a position above the cutting edge of the movable blade 2b according to the operation procedure described above, and then remove the plow comb. The main body case 1 is used by turning it upside down so that the movable blade 20 is located below the movable blade 2b.

In the electric hair clipper having such a structure, this invention enables the use of the plowing comb 20 to remove the hair that clings to the tip of the upper case 1a during round cutting. This first embodiment will be explained with reference to FIGS. 2 to 6. A plow-cutting comb 20 is connected to the comb holder 19 so as to be swingable left and right around a pivot 24, and the plow-cutting comb 20 and the vibrator 3 are connected to a pin hole 25 opened in a part of the plow-cutting comb 20, and a vibration Child 3
They are connected by a locking/disengaging means consisting of a pin 26 projecting upward from the interlocking arm 3d and engaging the pin hole 25. The pin hole 25 has a vertical hole portion 25a that is formed in an inverted T shape in plan view and is long in the front and back direction,
It has a horizontal hole 25b that communicates with the rear end of the vertical hole 25a and is long in the left-right direction. And plow comb 20
As shown in FIG. 2, the storage position A is completely stored in the upper case 1a, and as shown in FIGS. 4 and 5, from the storage position A to the tip of the upper case 1a In the shaving position B, which has been advanced to an intermediate position between the upper part of the cutting edge of the movable blade 2b, the pin 26 remains in the vertical hole part 25a of the pin hole 25, and the pin hole 25 and the pin 26 are in an engaged state. is obtained, and as shown in Fig. 6, the plow comb 2
0 is at the plowing position C, where the movable blade 2b has advanced from the shaving position B to the position above the cutting edge of the movable blade 2b, the pin 2
6 moves to the horizontal hole part 25b of the pin hole 25 and the vertical hole part 2
A disengaged state in which the engagement with 5a is released can be obtained.

In such a case, the notch 21 of the switch operation knob 17 that is in the OFF position within the knob guide hole 16
When the comb operation knob 18 is pushed up and engaged, and the switch operation knob 17 is moved to the forward ON position along with the comb operation knob 18, the reaping device 2 is driven and the plow-cutting comb 20 is activated. Since the tip reaches the plowing position C above the cutting edge of the movable blade 2b, this is used for plowing, but at this time the plowing comb 20 leaves the pin 26 in the horizontal hole 25a of the pin hole 25 and vibrates. Since it escapes from the vibrations of the child 3 and remains stationary, it does not pose any problem to plowing. When mowing, the switch operation knob 17 and the comb operation knob 18 are moved back in the knob guide hole 16 to a position just before reaching the off position, and the plowing comb 20 moves this tip above the cutting edge of the movable blade 2b. The pin 26 is positioned in the vertical hole 25a of the pin hole 25 when the pin 26 reaches the intermediate position between the tip of the case 1a, that is, the hair removal position B. Therefore, at this time, at the same time as the reaping device 2 is driven, the plow comb 20 receives the vibration of the vibrator 3 via the pin 26 and vibrates from side to side. 4) is forcibly shaken off by the vibration of the plow comb 20, and no longer accumulates on the movable blade 2b and the tip of the upper case 1a.

In this embodiment, the comb operation knob 18 is placed in the lower edge notch 23 of the knob guide hole 16, and the plowing comb 20 is stored in the upper case 1a.
Even when only the switch operation knob 17 is advanced to the on position to drive the reaping device 2, the pin holes 25 and pins 26 of the plow-cutting comb 20 are in an engaged state, and the plow-cutting comb 20 vibrates. However,
It does not cause any problem in shaving.

In such a case, if you want to completely stop the vibration of the plow comb 20, please refer to Figs. 7 and 8.
As shown in the figure, in the pin hole 25 provided in the plow-cutting comb 20, there is also a horizontal hole portion 2 at the front end of the vertical hole portion 25a.
5c are connected and the plow-cutting comb 20 is stored in the storage position A.
It is sufficient that the pin 26 is located in the horizontal hole 25c when the comb is placed in the comb 20. Accordingly, even if the reaping device 2 is driven, the vibration of the vibrator 3 will not be transmitted to the plow comb 20. disappears.

In any of the embodiments described above, a pin 26 is provided on the side of the vibrator 3 and a pin hole 25 is formed on the side of the plow-cutting comb 20 as a means for connecting and disconnecting the plow-cutting comb 20 and the vibrator 3. and vice versa, pin 26
It goes without saying that the pin hole 25 may be formed on the comb 20 side and the pin hole 25 on the vibrator 3 side.

In addition, the pin 26 and the pin hole 25 are employed as the tilting means, and the engaging means is composed of the vertical hole 25a of the pin hole 25 and the pin 26 that engages therewith, and the detaching means The pin 26 is inserted from the vertical hole 25a of the pin hole 25 to the horizontal hole
5b, the vibration of the vibrator 3 can be reliably transmitted or canceled to the plowing comb 20 with a simple structure, but the present invention is not limited to this, and any other method Good too,
For example, in the case of plow cutting, the plow cutting comb 20 and the vibrator 3 are separated from each other and placed facing each other so that they do not come into contact with each other, and the plow cutting comb 20 is strongly pressed against the vibrator 3 only during round cutting and hair removal. The vibration of the vibrator 3 may be transmitted to the plowing comb 20 by the frictional force generated between the contact surfaces of the two through a contact movement operation.

Note that the comb 20 is always in the hair removal position B.
Then, only when mowing the plow, let it come out from the shedding position B to the plowing position C.
It may be possible to perform forward and backward movement only between the shaving position B and the plowing position C.

As explained above, in the electric clipper of this invention, the plow comb 20 is connected to the movable blade 2b and the main body case 1.
The plow-cutting comb 20 is equipped so as to be swingable left and right in the gap between the tip of the plow-cutting comb 20, and the forward and backward stroke of the plow-cutting comb 20 is set at least between the plow-cutting position C and the shaving position B. and vibrator 3
are connected to each other through an engaging means such as a combination of a pin 26 and a pin hole 25, and the engaging means is an engaging means in which the plow comb 20 engages with the vibrator 3 at the shaving position B; It is composed of a disengagement means for disengaging from the vibrator 3 at the mowing position C. Therefore, during round cutting, the plowing comb 20 can be moved to the shaving position B and forced to vibrate from side to side in conjunction with the vibrator 3 through the engagement means, so that the movable comb 20 above the movable blade 2b Hair H can be automatically and reliably shaken off, the direction in which the cutting edge is traveling can be visually checked at all times, and the troublesome effort of having to frequently take a break to shake it off is reduced, making round cutting extremely easy. It is possible to cut the hair quickly and in good condition without cutting the hair. Further, since the vibrator 3, which is the driving body of the plowing comb 20 and the movable blade 2b, is used, the structure and assembly of this automatic hair removal mechanism can be extremely simplified.
