BACKGROUND OF THE INVENTION
The present invention is a hair set that wraps and stretches hair.ForThe present invention relates to a novel hair set device.
[0002]
[Prior art]
There are various types of devices for hair setting such as a hair dryer, a hair iron, a hair curler, etc., but they are common in that they are set by the action of heat by applying heat to the hair. The curled state and straight state of the hair are maintained by hydrogen bonds, which are weak bonds in the hair, and the above state of the hair can be changed by changing the hydrogen bond state. Since the bond breaks or shifts due to heat, the hair can be set by applying heat to the hair.
[0003]
[Problems to be solved by the invention]
However, when heat is applied to the hair, it is inevitably damaged by extreme reduction of the moisture content of the hair and modification of the protein of the hair, making it easier to split, making the hair easier to cut, and discoloring the hair Have the problem of Although it is possible to reduce the damage to the hair by moistening the hair when heating the hair, it does not replace the fact that the hair is heated to the temperature required for the hair set, but still has the above problems. Yes.
[0004]
The present invention has been made in view of these points, and the object of the present invention can be set without damaging the hair.Hair set equipmentTo provide.
[0005]
[Means for Solving the Problems]
UltrasoundIf the hair is vibrated by bringing the hair into contact with a vibrating body that vibrates in the region, the hair setting can be performed in the same manner as when heat is applied, although the reason is not clear. That is, as shown in FIG. 1 (a), when the hair 2 is brought into contact with the vibrating body 1 that vibrates in the ultrasonic region and the shape at the time of contact with the hair 2 is maintained for a while, the shape shown in FIG. As shown, even after the vibrator 1 is removed, the hair 2 retains its shape when it is in contact with the vibrator 1. When ultrasonic vibration is applied to the hair, frictional heat is generated in the hair. However, when ultrasonic vibration is applied to the hair, the hair temperature is lower by 15 ° C. or more than when heat is applied to the hair. From the fact that hair can be set, it is clear that the reason why the hair can be set is not the frictional heat, and it is considered that the ultrasonic vibration itself acts on the hydrogen bond.
[0006]
When contacting the hair with a vibrating body that performs ultrasonic vibration, methods such as winding the hair around the vibrating body, stroking the vibrating body on the hair, and pressing the hair against the vibrating body can be used. When stroking the body, it is effective to apply tension to the hair. When pressing the hair against the vibrating body, it is necessary to move the vibrating body along the hair in this state. It is valid.

It has a contact surface that applies ultrasonic vibration to the hair and brazes the hairAt the same time, the vibrating body projects a vibration damping member that attenuates ultrasonic vibration from a part of the contact surface.It has a special feature. By bringing hair into contact with the contact surface of the vibrating body, brazing can be performed by applying vibration in the ultrasonic region to the hair.In addition, since the vibration damping member protrudes, it is possible to prevent the vibrating body from touching the finger or skin directly, and to reduce the possibility of burns when the vibrating body touches the skin or finger. Can do.
As the vibrating body, the outer peripheral surface that is the winding surface of the hair is a contact surface with the hair, the one that has a pressing body that presses the hair against the contact surface of the outer peripheral surface of the vibrating member, and one surface is the contact surface Can be suitably used, such as a flat plate having a pressing body that presses the hair against the contact surface. The pressing body is pivotally attached to a main body portion having a vibrating body. A thing can be used suitably.
[0008]
It is desirable that the vibrating body vibrates in a direction perpendicular to the contact surface with which the hair contacts. In this case, a ring-shaped vibrator can be suitably used as the ultrasonic vibration generating means. In a direction limitedAbsent.
[0009]
other than this,The contact surface of the vibrating body with the hair may be an uneven surface, or a vibration transmission medium may be disposed on the contact surface. When the vibration transmission medium is used, a holding member for holding the vibration transmission medium on the vibration body is provided. It may be provided or the vibrating body may be formed of a porous metal so that the vibrating body itself becomes a holding member.
[0010]
It is also desirable to make the vibrating body freely rotatable and to add a load resistance to the rotation, and it is also desirable to provide a clutch mechanism that allows the vibrating body to freely rotate with respect to a force exceeding the load resistance.
Cover the cross-sectional shape of the contact surface of the vibrating body with the hair as a composite curve of multiple curvatures, or provide a cover that covers the part of the vibrating body and regulates the contact angle of the hair that contacts the contact surface of the vibrating body with the hair Or a brush-type protrusion having vibration transferability may be provided on the contact surface of the vibrating body with the hair, and the brush-type protrusion having vibration transferability is a predetermined area on the contact surface of the vibration body with the hair. In other areas, vibration-damping brush-type protrusions may be provided.
[0011]
The brush-shaped protrusions may be provided on the surface of a member that is detachable from the vibrating body. In this case, a vibration transmission medium is provided between the member that is detachable from the vibrating body and the vibrating body. It is good to arrange.
With regard to the control of vibration generation, a sensor for detecting the temperature of the vibrating body or the temperature of the hair in contact with the contact surface of the vibrating body and a control means for controlling the generation of vibration according to the detection result of the sensor may be provided. It is preferable that a sensor for detecting the moisture content of the hair contacting the contact surface of the vibrating body and a control means for controlling the generation of vibration according to the detection result of the sensor are provided. The sensor at this time may be arranged on the surface of the vibrating body, a pressing body that presses the hair against the contact surface of the vibrating body with the hair, or the inside of the vibrating body.

[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a hair set device according to the present invention is shown in FIG. 2, and its internal structure is shown in FIG. It comprises a vessel body 3 that functions as a cylindrical grip and a rod-like vibrating body 1 that protrudes from the tip of the vessel 3 and is pivotally attached to the tip of the vessel 3 in the case shown in FIG. As shown in FIG. 3, the hair set device provided with the pressing body 4 is driven by a DC power source 10 that outputs a DC power source, an oscillation circuit 11, and an oscillation circuit 11 to transmit an electrical signal in an ultrasonic region (almost). The body 3 includes a vibration generating unit including a transducer 12 that converts the mechanical vibration of 20 kHz to 200 kHz), a booster 13 that increases the amplitude of mechanical vibration by the transducer 12, and a power switch 30. One end of the vibrating body 1 is mechanically coupled to the booster 13 so that the vibrating body 1 vibrates due to vibration from the booster 13.
[0014]
Now, if the vibrating body 1 is vibrated by the vibration generating portion with the hair wound around the vibrating body 1 as shown in FIG. 1, the hair can be curled as described above. In addition, when the hair set is performed in this way, the hair 2 shows only a temperature lower by about 15 ° C. than the case where the hair set is performed by applying heat as described above, and the hair compared to before the hair set. The reduction rate of the moisture content of 2 is only 30%, and considering that the reduction rate of the moisture content of the hair 2 when hair is set by applying heat is 60 to 80%, the hair 2 is thermally damaged. You can see that it never gives.
[0015]
When applying vibration to the hair 2, since the vibration applied to the hair 2 becomes stronger when the hair 2 and the vibrating body 1 are in contact with each other with a strong contact pressure, the hair 2 is strongly wound around the vibrating body 1. It is desirable that the outer peripheral surface of the vibrating body 1 has a large friction coefficient so that this point can be answered. You may make it press the hair 2 currently wound around the vibrating body 1 toward the vibrating body 1 with the pressing body 4 as shown in FIG.2 (b).
[0016]
The method of bringing the hair 2 into contact with the vibrating body 1 is not limited to the above winding. As shown in FIG. 4, the hair can be set by stroking the vibrator 1 on the hair 2. However, since the contact pressure cannot be increased even when the vibrating body 1 is applied to the hair 2 in a free state, the vibrating body 1 is applied to the hair 2 while brushing with the brush 40 as shown in FIG. The vibrating body 1 may be stroked on the hair 2 in a state in which the clip 42 with the weight 41 attached to the tip of the hair 2 is attached as shown in FIG. Since the vibrating body 1 is applied to the hair 2 in a tensioned state, the contact pressure can be kept high. Of course, the vibrator 1 may be stroked while applying tension to the hair 2 by hand.
[0017]
The vibrating body 1 is not limited to a rod-shaped body, but can be applied to the above-described hair 2 even if it is a flat plate shape or a curved plate shape. When the vibrating body 1 has a flat plate shape, as shown in FIG. 7, the vibrating plate 1 is disposed on one surface of the vessel body 3 and the flat pressing body 4 pivotally attached to the vessel body 3 is attached to the vessel body 3. It is good that it is made to face the one surface. As shown in FIG. 8, the hair 2 can be brought into contact with the vibrating body 1 by sandwiching the hair 2 between the vibrating body 1 and the pressing body 4.
[0018]
In this case, in addition to performing a hair setting on a specific part of the hair 2, the hair setting can be performed by moving along the hair 2 as indicated by an arrow in FIG. In the case of using various methods, if a large number of small protrusions 31 and 43 are provided around the vibrating body 1 and the pressing body 4 in the body 3, the hair can be curled and arranged, as shown in FIG. Hair set to straight hair becomes easier.
[0019]
Further, when the hair setting device is moved along the hair 2, if the portion of the hair 2 sandwiched between the vibrating body 1 and the pressing body 4 is moved at a different angle from the base side of the hair 2, Since the applied vibration is slightly propagated from the portion of the hair 2 in contact with the vibrating body 1 to the other portion, the base side of the hair 2 is bent as shown in FIGS. 10 and 11. Hair set can be done.
[0020]
As shown in FIG. 12, the shape of the vibrating body 1 may be such that a plurality of protrusions 15 around which the hair 2 can be wound are protruded from the surface. A hair set that provides a curled portion and a straight portion can be performed. The protrusion 15 may not be capable of winding hair. If a large number of protrusions 15 are projected on the surface of the vibrating body 1, it is possible to increase the number of portions that come into contact with the hair 2 and give vibration to the hair 2.
[0021]
By the way, when applying vibration to the vibrating body 1 by the vibration generating portion, if the vibrating body 1 itself attenuates the vibration, vibration cannot be effectively applied to the hair 2. Alternatively, it is made of a hard polymer material. In particular, polyimide resin, fluororesin, PPS (polyphenylene sulfide) resin, and the like have advantages in terms of manufacturing the vibrator 1 compared to metals.
[0022]
As shown in FIGS. 13 and 14, the transducer 12, the booster 13, and the vibrating body 1, which are parts that vibrate, are provided with a flange 16 at a part that becomes a vibration node, and the body 16 is formed by the flange 16 part. It is attached to. Unnecessary damping of vibration can be avoided, and at the same time, the vessel 3 that also serves as a grip can be prevented from vibrating.
[0023]
At this time, the length L from the flange 16 to the tip of the cantilevered vibrator 1 is shown in FIG. 14 when the wavelength is λ (λ = M / f f: frequency, M: sound velocity in the vibrator). Thus, when L = 3/4 · λ, the tip of the vibrator 1 vibrates greatly. The tip of the vibrating body 1 is a part where the finger often comes into contact with the hair 2 when it is wound, and the fact that a large vibration occurs here may cause burns to the finger. As shown in FIG. 16, it is preferable to set the relationship between the wavelength λ and the length L so that the vibration node comes to the tip of the vibrator 1.
[0024]
Further, when L = 3/4 · λ or L = λ shown in FIG. 14 and FIG. 15, there is a node in the vibration body 1 in which vibration hardly occurs, and even if the hair 2 is brought into contact with this portion, the hair No vibration can be effectively applied to 2. Therefore, it is most preferable to set L = λ / 2 as shown in FIG. This is because the amplitude of the middle part of the vibrating body 1 where the hair 2 is most easily wound is maximized, and vibration hardly occurs at the tip of the vibrating body 1.
[0025]
When the vibration frequency range preferable for the hair set and the length L suitable for winding the hair 2 do not satisfy the relationship of L = λ / 2, the vibration frequency f may be changed as appropriate. For example, as shown in FIG. 17, the vibration frequency f is switched so that the states of L = λ / 2 and L = λ periodically occur, or the states of L = 2λ and L = λ periodically occur. The vibration frequency f is switched to The combination is not limited to the above. By switching the vibration frequency f in this way, it is possible to avoid a situation in which a vibration node is generated at a certain location in the middle of the vibrating body 1 and sufficient vibration cannot be applied to the hair 2 brought into contact with the portion. In addition, substantially uniform vibration can be applied to almost the entire region of the vibrator 1.
[0026]
The vibration direction in the vibrating body 1 is not limited, but it is effective with less energy to vibrate in a direction perpendicular to the surface of the vibrating body 1 on which the hair 2 contacts than the axial direction of the vibrating body 1. It is possible to hair set. From this point, it is preferable to use a transducer 12 called a ring vibrator that generates radial vibration shown in FIG. 18 for the vibrating body 1 that enables the hair 2 to be wound. In this case, The transducer 12 itself can be used as the vibrator 1 that contacts the hair 2. Moreover, since the transducer 12 (vibrating body 1) is cylindrical and hollow, heat generated during ultrasonic vibration can be effectively released. Of course, regarding the vibration direction, it is preferable that the rod-like vibrator 1 and the plate-like vibrator 1 also vibrate in a direction perpendicular to the surface thereof. Moreover, it is good to set it as the resonator about the vibration provided.
[0027]
By the way, it is not preferable that the skin is in direct contact with the vibrating body 1 that vibrates in the ultrasonic region as described above, and sometimes there is a possibility of causing a burn. This can be dealt with by providing the vibration damping member 6 for damping the vibration in a portion that may come into contact with the skin of the vibrator 1. However, since it is necessary to prevent the vibration damping member 6 from interfering with the contact of the hair 2 with the vibrating body 1, when the vibrating body 1 has a rod shape, FIG. 19 and FIG. As shown, a bowl-shaped vibration attenuating member 6 is projected from the outer peripheral surface of the vibrating body 1 at a predetermined interval in the axial direction of the vibrating body 1, or the tip end surface of the vibrating body 1 is a cap-shaped vibration attenuating member 6. Cover with. The hook-shaped vibration damping member 6 does not prevent the hair 2 from being wound around the vibrating body 1, but reliably prevents the vibrating body 1 from coming into contact with the scalp. Further, the cap-shaped vibration damping member 6 prevents the finger or skin from touching the distal end surface of the vibrating body 1. As the vibration damping member 6, a material having a large internal loss, for example, a soft synthetic resin or a rubber-based material can be suitably used. A brush-shaped member can also be used as the vibration damping member 6 disposed on the outer periphery of the vibrating body 1.
[0028]
In FIG. 21, in order to prevent the heat generated when vibration is generated from heating the vibrating body 1, the vibrating body 1 is made hollow and the air passage 17 is formed inside, and the periphery of the vibrating body 1 is The thing which formed the heat radiation hole 18 in the surface and the front end surface is shown. As shown in FIG. 22, it is also preferable to perform forced air cooling by blowing air from the container body 3 toward the air passage 17. As shown in FIG. 23, a cooling semiconductor element 19 that is a Peltier element may be arranged inside the vibrating body 1.
[0029]
When the vibration damping member 6 is provided on the outer peripheral surface of the vibrating body 1, the contact area between the vibrating body 1 and the hair 2 decreases as shown in FIG. It can be compensated by using a surface. Of course, in the case where the vibration damping member 6 is not provided, the contact area with the hair 2 can be increased by forming an uneven surface. As shown in FIG. 25, if the vibration transmission medium 20 is arranged on the surface of the vibrating body 1, vibration can be effectively applied to many hairs. As the vibration transmission medium 20, a gel-like medium can be suitably used.
[0030]
Although a liquid such as water can be used for the vibration transmission medium 42, in this case, as shown in FIG. 26, a holding member 21 that can hold the vibration transmission medium 20 such as felt or sponge is used as the vibration body. It may be arranged on the surface of 1. If the vibrating body 1 is formed of a porous metal, the vibration transmitting medium 20 can be held by the vibrating body 1 itself.
[0031]
In the case where the pressing body 4 is provided in the case where the vibration damping member 6 protrudes from the outer peripheral surface of the vibrating body 1, as shown in FIGS. 27 and 28, the pressing piece 44 fitted between the vibration damping members 6 is pressed. By providing the body 4, the hair 2 can be pressed against the vibrating body 1. In the figure, 45 is a rotating shaft of the presser body 4, and 46 is a spring biasing the presser body 4. The holding piece 44 here may be formed of a material having a large internal loss, like the vibration damping member 6.
[0032]
29 allows the vibrating body 1 and the pressing body 4 to freely rotate within a predetermined angle with respect to the container body 3 in the direction around the axis of the vibrating body 1 and a pair of springs 47, 47. Thus, the vibrating body 1 is urged from both sides in the rotational direction. If the hair curler device is moved along the hair 2 while the hair 2 is wound around the vibrating body 1 and pressed by the pressing body 4, the vibrating body 1 and the pressing body 4 resist the spring 47 against the body 3. As a result, a pulling force corresponding to the compression of the spring 47 acts on the hair 2. For this reason, the contact pressure between the hair 2 and the vibrating body 1 can be appropriately increased, and the ultrasonic vibration applied to the hair can be set to a strength suitable for the hair set.
[0033]
However, when the force exceeds the compression allowance of the spring 47, the contact pressure between the hair 2 and the vibrating body 1 becomes too high, so that the clutch mechanism 50 as shown in FIG. When the force becomes too strong, it is preferable that the vibrating body 1 and the pressing body 4 rotate freely with respect to the body 3 so that excessive tensile force does not act. The clutch mechanism 50 in the illustrated example is provided with a convex portion 51 on one of the opposing surfaces urged by a spring (not shown) in a direction in which they are in contact with each other, and a concave portion 52 into which the convex portion 51 is fitted, and Although the rotation is normally prevented by the engagement, the convex portion 51 is formed so as to rotate out of the concave portion 52 when the force becomes strong. However, the present invention is not limited to this configuration. The provision of the clutch mechanism 50 is also effective in the case where the pressing body 4 is not provided.
[0034]
The cross-sectional shape of the rod-shaped (tubular) vibrating body 1 is not limited to a circular shape. For example, it may be formed as an oval shape or a rice ball shape shown in FIG. 31, that is, a plurality of lines having different curvatures connected. Since the hair that contacts the portion with a small radius of curvature becomes a small curl, and the hair that contacts the portion with a large radius of curvature can have a large curl, curling with different sizes depending on how the hair 2 is applied to the vibrating body 1 Can be selected.
[0035]
As shown in FIG. 32, a cover 35 that covers substantially half of the outer circumferential surface of the vibrating body 1 is positioned at a predetermined distance from the outer circumferential surface of the vibrating body 1 (in the illustrated example, the outer circumferential position of the vibration damping member 6). Even if it arrange | positions, as shown in FIG. 33, curling of the radius different from the curvature radius of the outer peripheral surface of the vibrating body 1 can be performed. If the length or radius of the cover 35 in the circumferential direction is changed, the curling radius when the cover 35 is used can be changed. Of course, the cover 35 is made of a material that attenuates vibration.
[0036]
FIG. 34 shows a structure in which a brush-type protrusion 36 having vibration transmission properties is provided on the outer peripheral surface which is a contact surface of the vibrating body 1 with the hair 2. When the hair 2 is brought into contact with the vibrating body 1, the protrusions 36 are entangled with the hair 2, and when the hair is combed in this state, tension can be applied to the hair 2.
Instead of providing the above-described projections 36 having the above-mentioned vibration transmission property on the entire circumference of the vibrating body 1, as shown in FIG. You may make it provide the area which provided the protrusion 37 which has.
[0037]
Further, instead of directly projecting the protrusion 36 from the vibrating body 1, as shown in FIG. 36, a cylindrical body 38 having a brush-type protrusion 36 having vibration transmission properties may be detachably covered on the vibrating body 1. Good. Of course, the cylindrical body 38 is formed of a vibration transmitting member. As shown in FIG. 37, vibration transmission from the vibrating body 1 to the cylinder 38 may be performed reliably by interposing a vibration transmission medium 39 between the vibrating body 1 and the cylinder 38.
[0038]
Next, a control system for generating vibrations in the ultrasonic region will be described. 38 and 39, a sensor 70 capable of detecting the temperature of the vibrating body 1 or the temperature of the hair 2 is provided on at least one place on the outer surface of the vibrating body 1 or the pressing body 4 or the inside of the vibrating body 1. If the temperature of the vibrating body 1 or hair 2 to be detected is equal to or higher than a predetermined temperature, the switch 71 is turned off to stop the generation of vibration. Thermal damage to the hair 2 due to excessive temperature rise of the vibrator 1 can be prevented. In addition, the switch 71 is turned off even when the timer 72 that limits the continuous vibration occurrence time expires, so that the thermal damage to the hair 2 due to excessive temperature rise of the vibrating body 1 or excessive Application of ultrasonic vibration can be prevented. The sensor 70 may detect the moisture content of the hair 2 when it is disposed in a portion that contacts the hair 2. Since excessive temperature rise of the vibrator 1 causes a rapid decrease in the moisture content of the hair 2, thermal damage to the hair 2 can also be prevented by monitoring the moisture content.
[0039]
When the timer 72 is provided, assuming that the set process is performed again without obtaining a sufficient set effect in the first process, in order to shorten the continuous vibration occurrence time at the time of the re-process than at the time of the first process, As shown in FIG. 40, it is also preferable to provide two types of timers 72a and 72b having different time limits so that they can be switched.
It is also preferable that the generation of the ultrasonic vibration is performed for a predetermined number of times with a pause time as shown in FIG. Even if it does in this way, the excessive temperature rise of the vibrating body 1 and the thermal damage to the hair 2 accompanying this can be prevented, and the excessive provision of ultrasonic vibration can be prevented. In particular, it has been confirmed that intermittent generation of ultrasonic vibrations can suppress a rise in hair temperature even if ultrasonic vibration is applied to obtain the same hair setting effect as compared to the case of continuous generation. Note that the final stop of vibration generation may be controlled not by the above number of times but by the total time of vibration generation time.
[0040]
As shown in FIG. 42, the vibration generation control in the case of using the sensor 70 that detects the temperature may be such that the detected temperature falls within the range between the upper limit temperature and the lower limit temperature. In this case also, the ultrasonic vibration can be intermittently generated. Moreover, excessive application of ultrasonic vibrations can be prevented by stopping at the total number of vibration occurrence times or vibration generation times.
[0041]
In addition, in order to start the vibration, a switch (not shown) for detecting that the presser body 4 is closed is provided in the case having the presser body 4, and this switch is connected in series with the power switch 30. When the presser body 4 is not closed, it is preferable not to generate vibration.
[0042]
【The invention's effect】
As described above, the hair setting device according to the present invention includes the ultrasonic vibration generating means and the vibrating body that vibrates in the ultrasonic region by the ultrasonic vibration generating means, and the vibrating body is ultrasonically applied to the hair by contact with the hair. Since it has a contact surface that applies vibration to the hair and brazes it, hair can be easily set by applying vibration in the ultrasonic region to the hair, and vibration is applied in the ultrasonic region. Make hair setting such as bending and stretching hair by bringing the hair into contact with the vibrating bodyFrom the factCompared to the case where the hair is set by applying heat to the hair, the hair can be set with almost no heat damage to the hair, and the time required for the hair set is also the time required for the rise of heat. It can be lost in a short time.In addition, since the vibration body has a vibration damping member protruding from a part of its contact surface, the vibration body can be prevented from touching the finger or skin directly. The possibility of the occurrence of burns when touching the finger can be reduced.
[0044]
AndIf the outer peripheral surface, which is the hair wrapping surface, is a contact surface with the hair, the above-mentioned vibrating body can be obtained by curling hair and curling it. If the contact surface is equipped with a pressing body that presses the hair, the contact pressure between the vibrating body and the hair can be increased to ensure curling, and one surface becomes the contact surface. If it has a flat plate shape and is provided with a pressing body that presses the hair against the contact surface, it can be suitable for setting to straight hair. In addition, if a pressing body that is pivotally attached to a main body provided with a vibrating body is used, a pressing body that is excellent in usability can be provided.
[0045]
If the vibrating body vibrates in the direction perpendicular to the contact surface with which the hair comes in contact, it is possible to effectively obtain the action of ultrasonic vibration on the hair. If a ring-shaped vibrator is used as the ultrasonic vibration generating means at this time, the ring-shaped vibrator can be used as a vibrating body for contacting the hair. Reduction can also be achieved.
[0047]
MoreoverThe vibrating body protrudes a vibration damping member that attenuates ultrasonic vibration from a part of its contact surface.forIn addition, it is possible to prevent the vibrating body from directly touching the finger or the skin, and to reduce the possibility of burns when the vibrating body contacts the skin or the finger.
In addition, if the contact surface of the vibrating body with the hair is made uneven, or if a vibration transmission medium is arranged on the contact surface, the contact area between the hair and the vibrating body can be increased, and The vibration can be reliably applied. When a vibration transmission medium is used, if the vibration member is provided with a holding member for holding the vibration transmission medium, or if the vibration body is formed of a porous metal so that the vibration body itself becomes a holding member, the vibration transmission medium Handling becomes easy, and in particular, in the latter case, it is not necessary to use the holding member as a separate part.
[0048]
Making the vibrating body freely rotatable and adding a load resistance to the rotation can also give a good result in terms of giving a vibration with an appropriate tension applied to the hair, exceeding the load resistance. If a clutch mechanism that allows the vibrating body to freely rotate with respect to force is provided, there will be no problem due to excessive tension applied to the hair.
[0049]
If the cross-sectional shape of the contact surface of the vibrating body with the hair is a combined curve having a plurality of curvatures, curling with different sizes can be performed depending on the position where the hair is brought into contact even if the vibrating body is single. Even if a cover that covers a part of the vibrator and regulates the contact angle of the hair that contacts the contact surface with the hair of the vibrator, curling with a curvature different from the curvature of the vibrator itself Will be able to.
[0050]
A brush-type protrusion having vibration transmission properties may be provided on the contact surface of the vibrating body with the hair, and in this case, the brush-type protrusion serves as a member that applies tension to the hair and a member that transmits vibration to the hair. Therefore, the hair set can be performed reliably and quickly. In addition, the brush-type protrusions with vibration transmission characteristics are provided in a predetermined area on the contact surface of the vibrating body with the hair, and when vibration-damping brush-type protrusions are provided in the other areas, a characteristic curling is applied to the hair set. It will be something that can be done.
[0051]
The brush-type protrusions may be provided on the surface of a member that is detachable from the vibrating body. In this case, the case where the hair is brought into direct contact with the vibrating body is different from the case where the brush-type protrusion is used. A hair set can be performed. If a vibration transmission medium is disposed between the member that is detachable from the vibrating body and the vibrating body, vibration transmission from the vibrating body to the detachable brush-type protrusion can be ensured.
[0052]
Regarding the control of vibration generation, it is assumed that a sensor for detecting the temperature of the vibrating body or the temperature of the hair contacting the contact surface of the vibrating body and a control means for controlling the generation of vibration according to the detection result of the sensor are provided. In addition, it is possible to reliably prevent overheating of the vibrating body and thermal damage to the hair. When a sensor for detecting the moisture content of the hair contacting the contact surface of the vibrating body and a control means for controlling vibration generation according to the detection result of the sensor are provided, overdrying of the hair can be prevented. . The sensor at this time can perform appropriate detection by using the surface of the vibrating body, a pressing body that presses the hair against the contact surface of the vibrating body with the hair, or the inside of the vibrating body.
[0053]
Even with a timer that limits the continuous generation time of vibration, it is possible to prevent excessive temperature rise of the vibrating body and thermal damage of the hair. If there are multiple types of timers with different time limits and switching means for switching between these timers, hair damage when applying ultrasonic vibrations again when hair set is insufficient at one time Can be prevented appropriately.
[0054]
When the control means for intermittently generating the vibration is provided, the hair setting can be performed while further reducing the thermal influence on the hair.
In the control using the sensor, the generation of vibration is stopped by comparing the detection value by the sensor with the upper limit value, and the generation of vibration is resumed by comparing the detection value with the lower limit value. The hair set can be performed while further reducing the influence on the subject. The control means in these cases shall end the generation of the vibration by the number of times of the vibration generation operation or the total time of the vibration generation operation, so that the situation of excessive application of the ultrasonic vibration is not caused. Can do.
