DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an epilator used for beauty or the like.

[0002]

2. Description of the Related Art Epilators used for beauty etc.
A coil spring, which is wound tightly around an elastic metal wire, is bent and rotated about the direction of the winding axis, and hair is pinched by utilizing the gap difference between the adjacent coils on the outer circumference and inner circumference of the curved portion. There are hair removal types. The image is shown in FIG. 10. The coil spring 2 is curved and exposed between the left and right protrusions 1 a and 1 b at the front end of the case 1. The coil spring 2 rotates around the winding axis as a rotation axis. Then, as shown in FIG. 11, the hair is taken into the space P between the adjacent coils on the outer circumference side of the arc-shaped curved portion, and the space between the adjacent coils Q on the inner circumference side comes into close contact with the rotation.

[0003] Such an epilator has a firmer image of feeling pain during epilation than other types of epilators. The reasons are: There are many misses. This pulls the hair, but the gripped hair slips and stays in place, so it hurts but does not come out. Since the epilator is repeatedly applied to the skin to continue, the time for feeling pain is prolonged, and the person feels more painful. 2. Since the spring is bent in a ring shape, the hair is pulled toward the center of the ring.
Regardless of the flow in the direction in which the hair is growing, it is pulled in multiple directions, and the user feels pain. The two are the main ones.

Further, as shown in FIG. 12, the tip of the epilator is inclined with respect to the skin surface S 'which is structurally parallel to the outer surface of the epilator, and is used at the position of the skin surface S. The distance P between the adjacent coils on the outer peripheral side of the curved portion of
Therefore, even if the hair is taken in, the hair cannot be removed at this position, and therefore, the length of the hair that can be removed substantially from the point G on the outer peripheral surface of the coil to the skin surface S in the inclined state. And the radius r of the wire diameter of the coil spring 2
Hair cannot be removed unless the hair length is L + r or more.

[0005] Furthermore, the portion where the hair can be taken in as the depilation region of the epilator is only the most advanced portion of the coil spring 2 that is curved in an arc shape, and has a disadvantage that the range is considerably narrow.

[0006] Furthermore, as another problem, the use of an epilator may cause the depilated hair to scatter nearby or adhere to clothing, resulting in an unfavorable condition from the viewpoint of hygiene and aesthetics. Has occurred and a solution was needed.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides a drive mechanism for rotating and expanding and contracting a coil spring whose portion exposed from a housing is linear, so that adjacent coils come into close contact with or separate from each other as the coil expands and contracts. In this way, the hair is received while the coil spring is extended, and the hair is removed by the contracted and closely attached coil spring. As the drive mechanism, a motor that is a drive source for rotating the coil spring may be commonly used, or another motor may be provided for each. Further, the cross section of the metal wire constituting the coil spring is made to be a polygon including a circle or a square. With such a cross section, even short hairs can be reliably grasped from the root.

Further, the surface condition of the metal wire of the coil spring is finished in a satin-like shape, so that the surface is rough and rough. Compared to those with a conventional glossy smooth surface, the hair that is sandwiched is less slippery, and the gripped hair comes out reliably,
This can lead to an increase in the efficiency of the hair removal operation time.

Further, the epilator of the present invention has a built-in vibrator function. A vibrator is a means of giving the skin a different stimulus from hair loss to make the skin feel less pain during hair loss. Prior to hair removal, the skin is vibrated in advance and stimulated to reduce the pain of the skin, and then the hair is removed or stimulated by the vibration function while pulling out to disperse the skin pain. Also,
The vibration function is also effective for post-treatment of the skin where pain remains after hair removal.

The driving of the vibrator may be performed in conjunction with the driving of the coil spring by a motor for driving and rotating the coil spring, or a motor other than this motor may be provided and used. . Vibration makes the vibrator protrude from inside the housing to the outside, and even if this is driven,
Alternatively, a member having an eccentric center of gravity may be attached to the rotating shaft without providing a vibrator, and the whole housing may be vibrated by rotating the member. Furthermore, when two motors are used, each motor can be operated independently, and a switch having three switching positions for operating both motors simultaneously can be provided so that the motor can be used alone as a vibrator. Becomes

In order to prevent scattering of the depilated hair, a hair collecting device for collecting the depilated hair in the depilation region of the rotating coil spring exposed from the front end of the housing is provided. This hair collecting device is composed of a filter disposed in front of a depilation area of a coil spring and a fan disposed in front of the filter. To form a taxiway leading to the exhaust port.

If the filter for collecting hair is detachable as a separate member from the housing, it will be easier to process the collected hair, or if low cost is taken into account, the target is hair, so it is relatively removed. Since it is easy, it may be integrated with the housing.

Since the hair collecting device rotates the fan for suction, the air flow generated by the fan causes the hair in the vicinity of the hair removal area to be raised and raised, thereby creating a state in which the hair can be easily removed. In addition, the air flow cools the skin near the epilation area, so that pain during hair removal can be reduced.

Further, if a portion corresponding to the upper part of the depilation area near the front end of the housing is formed of a transparent material, the condition of the skin can be seen well when performing depilation, so that the depilation work with a sense of security can be performed. become. The transparent material may be partially formed as a transparent window, or when the housing is divided into upper and lower parts, the entire upper side thereof may be formed of a transparent material.

Various structures are conceivable for the expansion and contraction driving means of the coil spring. Generally, a structure in which one end of the coil spring is swung by a cam or a lever to push or pull the coil spring is used. A slidable grooved wheel with the telescopic movable side fixed is attached to the extension of the rotating shaft that rotates the coil spring,
The groove of the sheave wheel is formed in a plane perpendicular to the axis, and in this groove, a disk having an outer peripheral edge attached to a rotating shaft different from the rotation axis of the coil spring and inclined with respect to the plane perpendicular to the axis. There is a structure in which the inclined outer edge traces the inside of the groove, displaces it and swings the groove wheel in the axial direction to expand and contract the coil spring. In this case, contrary to the above, the groove of the sheave is formed so as to be inclined with respect to a plane orthogonal to the axis, and a rotating shaft different from the rotation axis of the coil spring is provided on the outside of a disk having a surface orthogonal to the axis. You may comprise so that a periphery may be engaged.

The expansion and contraction operation of the coil spring by the engagement between the groove of the groove wheel and the outer periphery of the disk is performed so that the time of close contact between adjacent coils of the coil spring is longer than the time of separation. Set the shape of the outer edge of the disk or the inclination of the groove. As a result, the close contact time is not instantaneous, and the hair taken in during the separated time keeps the close contact for a certain period of time, so that the hair can be reliably removed.

The relation between the rotation of the coil spring and the cycle of expansion and contraction is, for example, one expansion and contraction for two rotations and one rotation for three rotations.
It is desirable that the relationship of the number of rotations> the number of times of expansion and contraction, such as the number of times of expansion and contraction, be used.

In this case, also, in the housing,
A vibrator portion is disposed, and the driving of the vibrator portion is performed in conjunction with the driving of the coil spring by the motor, or the vibrator portion is performed by a motor provided separately from the motor, and / or the front end of the housing. A more effective operation can be performed by providing a hair collecting device that collects the hair that has been removed in the hair removal region of the coil spring that is exposed and rotates.

[0028]

1 to 9 and FIGS. 13 to 15 are for explaining the present invention. FIG. 3 is an external view of the whole. Reference numeral 1 denotes a housing which is formed by molding with an impact-resistant resin, and has a shape such as a shaver which is easy to grasp and suitable for carrying. Reference numeral 21 denotes a coil spring, which is almost entirely exposed linearly from an opening 90 at the front end of the housing 1 and in which an elastic steel wire or the like is tightly wound. Reference numeral 3 denotes a switch that exposes an operation unit outside the housing 1, accommodates a switching mechanism (not shown) in the housing 1, and turns on and off the power of a motor that rotates the coil spring 21 by operating the switch 3. Reference numeral 4 denotes a battery cover which is opened and closed when the battery in the housing is replaced.

FIG. 1 is a front view showing a state in which one surface of a housing 1 is removed, and FIG. 2 is a side view showing the main part of the internal structure, but details of the internal structure are omitted to avoid complication. It is. Reference numeral 6 denotes a small motor. The rotation of the rotating shaft 82 rotates the coil spring 21 via a gear 83 at the tip of the rotating shaft 82, and the battery 9 in the housing 1 is rotated.
It is powered by and operates. Although the wiring is not shown, the switch 3 is interposed between the battery 9 and the motor 6, and the motor 6 is turned on and off by operating an operation unit of the switch 3. The battery may be a dry battery, a rechargeable battery, or a rechargeable battery provided with a charging device compatible with an AC power supply.

Reference numeral 21 denotes a coil spring which overlaps with the above, and has a coil-shaped winding shaft formed substantially linearly, and is disposed in the opening 90 at the front end of the housing 1 so that the outer peripheral surface is desired. The motor 6 rotates the gear 83 via the shaft 82,
Since the gear 83 rotates the gear 85 directly connected to one end of the coil spring 21, the coil spring 21 rotates at a predetermined rotation speed. On the other hand, a gear 81 is also attached to the shaft 82 of the motor 6, which transmits rotation to the gear 87, and the eccentric projection 87 a provided on the shaft of the gear 87
8 is engaged with the engaging portion 88a at one end and is reciprocally rocked.

The lever 88 is supported by a shaft 88b in the vicinity of the center, and the opposite end 88c is fixed to one end of the coil spring 21, so that the lever 88 is rotated as shown in FIG. It swings in the directions of arrows P and Q. Accordingly, the end 88c of the swinging lever 88 repeatedly presses and releases the end of the coil spring 21 opposite to the end connected to the gear 83, and expands and contracts. In the present embodiment, when the action of the lever 88 does not work, the coil spring 21 has a gap between adjacent coils, and when working, that is, when pressed, the coil spring 21 comes into close contact. The coil spring 21 may be extended or operated to release the extension.

With such a configuration, the coil spring 21 that rotates with the rotation of the motor 6 makes close contact between adjacent coils at a certain point in time, and creates a space at the next time. The hair to be depilated can be induced and taken in when it occurs, and the taken-in hair can be depilated when it comes into close contact.

In this embodiment, one end of the lever 88 is engaged with the eccentric projection 87a to swing the lever 88. However, the drive mechanism of the lever 88 is not limited to this. Instead, for example, a cam mechanism may be used.

The sectional shape of the coil spring 21 may be circular, but FIG. 4A shows an embodiment having a characteristic sectional shape. The sectional shape of the coil spring 21 used here is shown in FIG. They are square, hexagonal, and octagonal as shown in (A), (B), and (C). By adopting such a cross section, conventionally, in the case of a circular cross section, short hairs with a diameter less than the diameter of the wire diameter could not be grasped, or even if they were grasped, they could not be securely grasped and were easily pulled out, but securely grasped from the root. Will be able to Also, in the circular cross section, adjacent lines have point contact, but by making them square or polygonal, they come into surface contact, gripping hair is less likely to slip, and there is little loss of pull out, so it is less likely to feel pain Become.

Another feature of the present invention is the condition of the surface of the coil spring 21. As an example, by finishing the surface into a satin finish and making it rough and rough,
Compared with the conventional glossy state of the surface, the pinched hair is less slippery and the gripped hair can be reliably pulled out, leading to an increase in the efficiency of the hair removal operation time.

Although the rotation speed of the coil spring 21 is constant in the above-described embodiment, a function for adjusting the speed from a low speed to a high speed, for example, in about three stages is provided.
Various requirements can be met.

FIG. 5 shows the relationship between the hair and the skin surface by the epilator of the present invention. Of the coil spring 21,
Since the outer peripheral surface which is in direct contact with the skin surface S rotates and expands and contracts while being in contact with the skin surface S, the hair taken in when the adjacent coils are opened can be surely depilated, thus forming the coil spring 21. The hair having a length corresponding to the diameter R of the wire rod can be depilated, and the hair which is much shorter than the conventional one shown in FIG. 12 can be depilated.

The above embodiment will be described in more detail with reference to FIGS. In FIG. 6, 1 is a housing, 6
Denotes a motor, and 9 denotes a battery, which is the same as in the above embodiments. Reference numeral 21 denotes a coil spring, which is formed substantially linearly without curving as described above, and is disposed as desired in the opening 90 between the left and right protrusions 1a at the tip of the housing 1. The motor 6 has gears 91a, 91b, 91c,
The gear 91g is rotated via 91d, 91e, and 91f, and the gear 91g rotates the coil spring receiver 92 directly connected to one end of the coil spring 21, so that the coil spring 21 rotates at a predetermined rotation speed. On the other hand, a gear, an eccentric cam, and the like are separately provided on the shaft of the motor 6, and a structure for expanding and contracting the coil spring 21 is provided.
The coil spring 21 opens and closes a gap between adjacent coils, but the illustration is omitted.

With such a configuration, the coil spring 21 that rotates with the rotation of the motor 6 makes close contact between adjacent coils at a certain point in time, and creates a space at the next time. The hair to be depilated can be induced and taken in when it occurs, and the taken-in hair can be depilated when it comes into close contact.

The outer diameter front surface of the coil spring 21 is 21a.
And In this embodiment, the outer diameter front surface 21a of the coil spring 21 is located at the same position as the front surface of the left and right protrusions 1a at the tip of the housing 1 as shown in FIG.
(B), the left and right protrusions 1 at the tip of the housing 1
a from the front surface or a position slightly protruding, or (C) of FIG.
In this case, the position is slightly retracted from the front surface of the left and right protrusions 1a at the front end of the housing 1, or in any case, they are arranged at substantially the same level. And
Means for doing so is simply coil spring 2
This is performed by changing the winding diameter of the coil spring 21 instead of arranging the position of the coil spring 21 back and forth.

By doing so, the exposed surface of the coil spring 21 from the housing 1 can be effectively brought into contact with the skin.

Further, by increasing the winding diameter of the coil spring 21, the wire diameter of the wire used for the coil spring 21 can be increased without using a large driving force for driving the coil spring 21 to expand and contract. The hair can be pulled out without fail.

Further, since the wire diameter is large, when a pressure for hair removal is applied between the adjacent coil wires, the winding of the spring is hard to collapse, and the hair can be securely sandwiched and removed.

In addition, as the diameter of the wire is increased, the number of turns constituting the entire length of the coil spring 21 is reduced, so that pain caused during hair removal can be reduced.

FIGS. 8 and 11 illustrate the operation of the coil spring. FIG. 1 shows a conventional example.
In 1, the distal end P portion of the coil spring 2 having an arc shape opens between adjacent coils, and hair enters into this portion, and between the adjacent coils closes in the rear side Q portion, and the hair is removed in this portion. As it will be pulled out, take in the hair,
Both hair removal is limited to a specific portion, and the rear side Q portion is pressed between adjacent coils, so that a large pressure is applied and a large driving force for rotating the coil spring 2 is required. 8 (A) and 8 (B) which illustrate an example of the present invention, the gap R when the coil spring is extended as shown in FIG. 8 (A). The hair can be taken in from any direction without being limited to a specific portion as in the prior art, and when the coil spring is contracted as shown in FIG. Without being limited to a specific portion, it is possible to reliably remove hair taken in the gap R by being uniformly closed, and if the portion is exposed from the housing, a wide range of hair removal can be performed. Also drive Those living also small.

As described above, according to the embodiment using the linear coil spring of the present invention, any part of the part exposed from the front end of the housing can be depilated under the same condition, and the coil spring having an arc shape can be used. An easy-to-use epilator can be obtained without any direction of epilation as compared with a conventional epilator used.

FIG. 9 shows an embodiment in which a vibrator function and a hair collecting function are added to the embodiment of the present invention described above. Except for the additional function, the description is omitted since it is the same as the above.

The rotating shaft 82 of the motor 6 and the gear 7
1 is mounted, a gear 72 is attached to the gear 1, and a shaft 73 is rotated. A vibrator 74 having a center of gravity eccentric is attached to one end of the shaft 73. With the rotation of the shaft 73, the vibrator 74
By vibrating the entire epilator and pressing the lower surface against the skin, a vibrator device can be obtained. It is more effective if a part of the housing 1 is made flat and this part is brought into contact with the skin of a human body.

With such a vibrator device,
This is a means of giving the skin a different stimulus from hair loss to make the skin feel less pain during hair loss. Prior to hair removal, the skin is vibrated in advance and stimulated to reduce the pain of the skin, and then the hair is removed or stimulated by the vibration function while pulling out to disperse the skin pain. In addition, the vibration function is also effective for post-treatment of the skin in which pain remains after hair removal.

The vibrator device may be driven by a motor different from the motor for rotating the coil spring. Further, a plurality of protrusions may be provided on a part of the housing 1. Further, an opening hole may be provided in the housing 1, the tips of a plurality of pins may be exposed from the holes, and the pins may be vibrated by a cam device or the like to give a vibration at the tip of the pin.

Also in such an example, when two motors are used, each motor is operated independently,
Further, by providing a switch for operating both of them at the same time, it is possible to use the switch alone as a vibrator.

The epilator shown in FIG. 9 is provided with a hair collecting device that performs a function of treating the depilated hair, in addition to the vibrator device described above. The fan device 75 is connected to the shaft 73,
As the fan rotates, the fan device 75 operates, and the fan device 75 that creates an air flow from the opening 90 of the housing 1 through the duct 76 is arranged. A filter unit (not shown) for catching the removed hairs And has an effective action.

By the operation of the fan device 75 driven by the shaft 73, the hair subjected to hair removal treatment is sucked from the vicinity of the tip of the housing 1, near the opening 90, which is the hair removal area, from the vicinity thereof, and is captured by the filter unit. Details of the filter unit are omitted.

The vibrator device and the hair collecting device
Both may be provided, but a suitable effect can be obtained with either one.

FIGS. 13 and 14 show an embodiment in which the extension and retraction of the coil spring is performed by means different from the above. In FIG. 13, reference numeral 6 denotes a motor, and reference numeral 83 denotes a gear, which is driven by the motor 6. The rotation of the gear 83 is transmitted from the gear 85a to the gear 85b. Gear 85
b is coupled to the coil spring 21 to rotate it. The gear 85b rotates a long shaft 85c penetrating the inside of the inner diameter of the coil spring 21. The shaft 85c
At the other end, a groove wheel 102 is rotatably and slidably supported on a shaft 85c. The end of the coil spring 21 is also fixed to the sheave 102. The grooved wheel 102 is provided with a groove 102a that makes a round around the outer peripheral surface. Groove 10
2a is formed in a plane orthogonal to the axis 85c.

On the other hand, the gear 85a
A shaft 100 that rotates together with the shaft 100 is provided. An outer peripheral portion 101a of the disk 101 is formed in a shape inclined with respect to a plane perpendicular to the shaft 100, and the outer peripheral portion 101a enters the groove 102a of the sheave 102 to form an engaged state. are doing. It should be noted that the groove wheel 102 can be provided on the shaft 100 and the disk 101 can be provided on the shaft 85c.

With such a configuration, the inclined outer peripheral portion 101a of the disk 101 is rotated by the rotation of the shaft 100,
Since the groove 102a traces the inside of the groove 102a, the groove wheel 102 swings along the shaft 85c to extend and contract the coil spring 21 having one end fixed to the groove wheel 102, and makes contact between adjacent coils of the coil spring 21. The separation operation is performed,
Hair taken in at the time of separation is depilated at the time of close contact.

By setting the inclination shape of the outer peripheral edge portion 101a of the disk 101, the close contact and the separation operation between the adjacent coils of the coil spring 21 can be controlled. FIG. 14 shows an example of this, in which the horizontal axis indicates the number of rotations of the coil spring, and the vertical axis indicates the interval between adjacent coils. With the rotation r of the horizontal axis, the interval R changes from zero to full on the vertical axis. It will rock. In FIG. 14A, one expansion and contraction is performed while the coil spring makes two rotations.
Predetermined time interval T ₁ contact time at that period, for setting the slope shape of the outer peripheral edge portion 101a of the disc 101 as contact is maintained. Also, it is performed once the stretch while the coil spring in FIG. 14 (B) is 3 rotates, the time constant as a contact time T ₂ of the within that period, the outer circumferential edge of the disc 101 as contact is maintained The inclination shape of the portion 101a is set.

As described above, by setting the contact time not to be instantaneous but to be maintained for a certain period of time, the hair taken in within the separated time is depilated during the contact time that is continued for a certain period of time, and the hair removal is ensured. It becomes something.

Note that the relationship between the rotation of the coil spring and the cycle of expansion and contraction is, for example, one every two rotations as in the above embodiment.
It is desirable that the relationship of the number of rotations> the number of times of expansion and contraction, such as one time expansion and contraction, three times expansion and contraction, is used. This relationship can be obtained, for example, by adjusting the gear ratio between the gear 85a and the gear 85b.

FIG. 15 is a view showing another embodiment of the means for transmitting the rotation of the motor to the coil spring. 6
Is a motor, the rotation of which is transmitted to a shaft 203 via gears 200 → 204. 201 is a bearing. Axis 2
03, a friction wheel 205 made of an elastic material is fixed, and the outer peripheral surface 205a of the friction wheel 205
Coil spring support 2 rotatably supported by 2
In this case, the outer peripheral surface of the coil spring 21 fixed at 06 is driven in contact. As a result, efficient rotational driving is performed, and since no gear is required on the axis of the coil spring, the front surface of the outer diameter of the coil spring 21 is located at the same position as the front surfaces of the left and right protrusions 1a at the tip of the housing 1. It is possible to freely select a slightly protruding position or a slightly retreated position, and it is possible to arrange them at almost the same level.

As described above, according to the present embodiment, it is possible to obtain an easy-to-use epilator that can reliably remove hair, has less pain, can treat short hair, and can easily treat the removed hair. Become.

[0063]

As described above, according to the present invention, since the cross section of the metal wire constituting the coil spring has a polygonal shape including a circle and a quadrangle, even short hairs can be reliably grasped from the root. Now you can do it. Also, in the circular cross section, adjacent lines were point contacts, but by adopting a square or polygon, the adjacent lines were in surface contact, making it difficult for gripped hair to slip, and with less loss of removal I felt less pain.

Also, since the surface condition of the metal wire of the coil spring is finished in a satin shape and is made rough, the hair is less slippery than the conventional one having a smooth and glossy surface. The hair was reliably pulled out, leading to an increase in the efficiency of the hair removal operation time.

Instead of rotating a coil spring having a curved shape as in the prior art, the coil spring is arranged in a straight line, and the hair is taken in the open gap by expanding and contracting the hair, and the hair is removed in a closed state. , Even with short hair.

Further, regarding the portion of the linear coil spring exposed from the housing, the outer diameter surface of the spring is the same as the front end surface of the housing, or slightly protrudes, or slightly retracts. ,
The conditions for contact with the skin were improved, and the hair removal efficiency was improved.

Further, by doing so, the diameter of the coil spring is increased, so that the diameter of the wire used can also be increased. This results in an effect that the driving force for expanding and contracting the coil spring is small, and the hair that is pinched can be reliably removed.

Further, when pressure for hair removal is applied between the wires, the winding of the spring is not easily broken, and the hair can be reliably inserted and removed.

As the wire diameter is increased, the number of windings of the coil can be reduced, which also has an effect of relieving pain during hair removal.

Further, when a linear coil spring is used to expand and contract, a smaller driving force is required than when a circular coil spring is rotationally driven, and there is an advantage that the motor is reduced in size, which is economical. Also, the entire epilator can be made smaller.

Further, since any part of the part exposed from the front end of the housing can be depilated under the same condition, there is no direction of the depilation, so that it is easy to use.

The vibrator can give the skin a stimulus different from hair loss to make the skin feel less pain during hair loss. Vibrate the skin before hair removal,
It has the effect of stimulating the skin to make the pain of the skin dull and then removing the hair, or stimulating it with the vibration function while pulling it out to disperse the pain in the skin.
In addition, the vibration function is also effective for post-treatment of the skin in which pain remains after hair removal.

For hair removal and vibrator,
If different motors are used, operate the motors independently and provide a switch that activates both motors at the same time, thereby realizing multi-functionality that can be used independently as a vibrator. Was completed.

Also, in the design, since the exposed portion of the coil spring is short, it is not necessary to provide a cover means for exposing only the lower portion of this portion and covering the upper portion, so that there is an effect that the epilation state can be visually observed.

Further, by providing a fan and a filter for collecting the depilated hair, the depilated hair may be scattered in the vicinity or adhere to clothing even if the epilator is used.
In terms of hygiene and aesthetics, unpleasant conditions do not occur, and the treatment of depilated hair is simple and easy.

Then, the air flow generated by the fan causes the hair on the skin near the hair removal area to rise and create a state in which the hair can be easily removed.
In addition, since the air flow cools the skin near the depilation area, there is also an effect of reducing pain during hair removal.

The coil spring is driven to expand and contract by a groove wheel and a disk, and one of them is inclined so that the compression state continues for a certain period of time. Is maintained for a certain period of time, not instantaneously, so that hair removal can be further ensured.
