TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an ultrasonic hairbrush adapted to ultrasonically vibrate a strip for combing hair by ultrasonic vibration generated by ultrasonic generating means.
[0002]
[Prior art]
Conventionally, as a hairbrush, a hairbrush that vibrates a wire-like brush body for combing hair is known (for example, see Patent Literature 1 and Patent Literature 2).
[0003]

[0005]
[Problems to be solved by the invention]
However, the above-described mechanical vibration brush and ultrasonic brush have the following problems.
[0006]
With mechanical vibrating brushes, mechanical vibrations have a higher frequency than the repetitive massage performed by fingers or hands, but they are vibrations at a lower frequency, so they propagate relatively widely on the surface of the scalp but deeply into the scalp. And a massage effect can be obtained only in a shallow region of the scalp surface layer.
[0007]
On the other hand, in the ultrasonic brush, since the ultrasonic vibration is a vibration at a high frequency, it can be transmitted to a deep region inside the scalp. However, when applying ultrasonic vibrations to the human body, the intensity of the ultrasonic vibrations must be low and moderately suppressed because an excessively high intensity may cause a tissue destruction effect of the human body. Therefore, the intensity of the ultrasonic vibration must be reduced despite having the basic effect that the ultrasonic vibration brings a heating effect or a vasodilatory effect on the scalp and a higher massage effect can be expected. However, this basic effect is not fully exploited. Also, since the ultrasonic vibration is transmitted as vibration in the direction in which the brush body extends, the ultrasonic vibration is not transmitted to the scalp in a radial direction perpendicular to the direction, that is, the contact surface spread in a direction along the surface of the scalp, The massage effect cannot be obtained in a wide range.
[0008]
Therefore, an object of the present invention is to provide an ultrasonic hairbrush that can obtain a high massage effect in a scalp surface layer and inside a wide area while extracting the basic effect of massage by ultrasonic vibration.
[0009]
[Means for Solving the Problems]
According to the present invention, the object is to provide a brush body that supports a plurality of linear or rod-shaped strips for combing hair at the base of the strip, and an ultrasonic wave that is attached to the brush body and generates ultrasonic waves. An ultrasonic hairbrush, comprising: a generator and configured to vibrate the strip by ultrasonic vibration generated by the ultrasonic generator, wherein the machine is mounted on the brush body and generates vibration by mechanical motion. This is achieved by providing a mechanical vibration generating means and transmitting the ultrasonic vibration and the mechanical vibration to the plurality of strips.
[0010]
According to the present invention, the mechanical vibration and the ultrasonic vibration transmitted to the scalp are applied to the scalp surface layer in the depth direction into the scalp, and at the same time, the mechanical vibration is applied to the scalp surface layer with an overlapping region. Given inside the scalp. As a result, in the overlapping region, ultrasonic vibration is applied to the blood vessel or the like compressed and relaxed by mechanical vibration, frictional resistance between the blood vessel and the blood is reduced, and the flow of the blood and the like becomes smooth. . Further, even outside the overlapping region (the inner layer of the scalp deeper than the overlapping region), the blood vessel or the like to which ultrasonic vibration is given under the influence of mechanical vibration and ultrasonic vibration due to the overlapping region is applied. Since blood and the like extruded by being compressed and relaxed by mechanical vibration flow from the adjacent scalp surface region, frictional resistance between blood vessels and the like decreases as described above, and blood and the like flow smoothly. . Further, since the stria vibrates in the radial direction due to mechanical vibration, the ultrasonic vibration transmitted to the distal end portion of the stria can be widely transmitted to the surface of the scalp. As described above, a high massaging effect can be obtained in a wide range due to a synergistic effect of mechanical vibration and ultrasonic vibration.
[0011]
In the present invention, the brush body has a support portion for supporting the plurality of strips, and a grip portion extending from the support portion for gripping by a user, wherein the support portion and the grip portion are elastic members. It is preferable that the connection be made via the connector because the vibration between the supporting portion and the gripping portion is insulated and the vibration from the gripping portion to the user is reduced, so that the usability is improved.
[0012]
The mechanical vibration generating means is a vibration motor having a weight eccentrically attached to the motor shaft, and the axis of the motor shaft has a surface including a direction in which the grip portion extends and a direction in which the strip extends. Perpendicular to, the striation vibrates not only in the radial direction but also in the extending direction, so in the radial direction of the striation, the width of contact with the scalp increases, and the extending direction of the striation Then, the contact pressure of the strip on the scalp is improved. Thereby, a higher massage effect can be obtained.
[0013]
Further, in order for the ultrasonic waves to be effectively transmitted to the strip, the brush body preferably has a region portion supporting the strip having a larger mass than other portions. Further, it is preferable that the strip is tapered toward the free end.
[0014]
In addition, the grip portion is located substantially parallel to the surface of the support portion on a side opposite to the strip in a direction in which the support extends to the surface supporting the strip, and is located on the support portion. It can also be connected. By doing so, the brush body does not become longer in only one specific direction, so that a force can be directly applied to the strip when the user grips the grip portion, so that it is easy to use. Will be better. It is also convenient when carrying an ultrasonic hairbrush in a limited space such as a bag when traveling, etc.
[0015]
Further, the ultrasonic generator has a high-frequency oscillator that receives power supply to generate high frequency, and an ultrasonic vibrator that receives and excites high frequency from the high-frequency oscillator, and the high-frequency oscillator is attached to a grip portion. The ultrasonic vibrator may be attached to a support. By doing so, the high-frequency oscillator can be arranged by effectively utilizing the internal space of the gripping portion. Also, since the ultrasonic vibrating body that mechanically vibrates is arranged at a position close to the strip, and an electronic component such as a high-frequency oscillator that is not preferably subjected to mechanical vibration is arranged at a position far from the strip, Failure of electronic components can be reduced.
[0016]
In addition, the ultrasonic wave generating means and the mechanical vibration means charge the brush body by supplying power to the rechargeable battery if these driving units are connected to a rechargeable battery built in the brush body. And the power supply from the charging stand to the rechargeable battery is formed between the brush body and the charging stand when the brush body is supported by the charging stand. It can be performed through an inductive coupling. By doing so, the user can charge the rechargeable battery in the brush main body only by hanging and supporting the brush main body on the charging stand when the brush is not used, so that power is supplied to the rechargeable battery in the brush main body. This eliminates the need for replacing the cord and the battery, and the user can easily handle it even when used in a bathroom or the like. In addition, since the power supply from the charging stand to the rechargeable battery in the brush body is performed via electromagnetic induction coupling, the contacts for supplying power from the charging stand to the rechargeable battery in the brush body are connected to the charging stand and the brush body. This eliminates the need for a contact-related trouble such as a defective contact, and also allows the internal space of the brush body to be easily made water-tight so that the ultrasonic hairbrush can be used in a humid place such as a bathroom.
[0017]
Further, if at least the striae of the brush body is formed of a resin or the like containing tourmaline powder, mechanical vibrations and ultrasonic vibrations are transmitted to the scalp while promoting metabolism of the human body by negative ions generated by tourmaline. Therefore, a high massage effect can be obtained by these synergistic effects. According to the present invention, tourmaline is subjected to mechanical vibration or ultrasonic vibration, so that more negative ions can be generated. Further, in a bathroom or the like, since the room temperature is high and the amount of water is large, more negative ions can be generated.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0019]

The cover part 3b is attached to the transmission part 3a so as to cover the ultrasonic vibration body 8, the vibration motor 6, and the like. The plurality of strips 2 provided on the transmission part 3a of the support part 3 are arranged in a zigzag as shown in FIG. The strip 2 formed integrally with the transmitting portion 3a transmits the ultrasonic vibration from the ultrasonic vibrator 8 to the scalp through the distal end of the strip 2, and in order to perform the transmission efficiently. It has a tapered shape, and has a substantially flat surface so that the tip portion comes into surface contact with the scalp.
[0022]
The support section 3 is provided with a cover section 3a for transmitting the vibrations of the ultrasonic vibrator 8 and the vibration motor 6 to the transmission section 3a in a concentrated manner so as to reduce the escape toward the cover section 3b. It is formed so as to have a mass larger than 3b, that is, thicker than the cover portion 3b.
[0023]
On the other hand, the grip part 4 has an internal space, and a power source 10 such as a dry battery or a rechargeable battery is provided in the internal space. In the present embodiment, the brush main body 1 has a watertight structure in the inner space of the support portion 3 and the grip portion 4 so that the ultrasonic hairbrush can be used in a wet place such as a bathroom. . In order to suppress the vibration from the support part 3 to the grip part 4 and improve the usability, the support part 3 and the grip part 4 are connected via an elastic body 5. Vibration between the shaft and the gripper 4 is well insulated. As the elastic member 5, various elastic members such as rubber and spring can be applied as long as the vibration between the support portion 3 and the grip portion 4 is insulated.
[0024]
As shown in FIG. 2, the ultrasonic vibrator 8 attached to the transmitting section 3a of the support section 3 is connected to a high-frequency oscillator 7 as shown in FIG. In the present embodiment, the high-frequency oscillator 7 is attached to the inner surface of the cover 3b of the support 3 (see FIG. 2), and controls the ultrasonic frequency of the ultrasonic vibrator 8 to a set value. The control unit 9 is connected. The control unit 9 is attached to the inner surface of the cover 3b, and is connected to a power supply 10 provided in the grip unit 4 via a power switch 11. The power switch 11 allows the user to supply or cut off power from the power source 10 to the control unit 9 from outside the cover 3b. The ultrasonic vibration from the ultrasonic vibrating body 8 excited in this way is transmitted to the strip 2 via the transmitting portion 3a. The set value of the frequency of the ultrasonic vibration in the ultrasonic vibrator 8 is preferably 20 kHz to 10 MHz, and more preferably 30 kHz to 2 MHz.
[0025]
The vibration motor 6 attached to the transmission section 3a of the support section 3 as shown in FIG. 2 is connected to the control section 9 as shown in FIG. The control unit 9 controls the power to the high-frequency oscillator 7 as described above, and also controls the power to the vibration motor 6 so that the frequency of the mechanical vibration by the vibration motor 6 becomes a set value. As described above, the vibration motor 6 generates mechanical vibration, and the mechanical vibration is transmitted to the strip 2 via the transmission unit 3a. The set value of the vibration frequency of the mechanical vibration by the vibration motor 6 is preferably 100 Hz to 300 Hz, and the rotation speed of the vibration motor 6 at this time is 6000 rpm to 18000 rpm.
[0026]
Here, the configuration of the vibration motor 6 will be described in detail with reference to FIG. FIG. 4 is a diagram showing a schematic configuration of the vibration motor 6.
[0027]
As shown in FIG. 4, the vibration motor 6 includes a motor 6a having a rotating shaft 6b, and a weight 6c eccentrically attached to the rotating shaft 6b of the motor 6a. The axis of the rotating shaft 6b is oriented in the Y direction perpendicular to a plane including the X direction, which is the direction in which the grip 4 of the brush body 1 extends, and the Z direction, which is the direction in which the strip 2 extends. . Therefore, the rotation in the X and Z directions is generated by the swiveling rotation of the eccentric weight 6c by the rotation of the rotating shaft body 6b about the axis in the Y direction. Due to the vibration of the vibration motor 6 in the X and Z directions, the strip 2 vibrates not only in its radial direction, that is, in the X direction shown in FIG. It has become.
[0028]
Next, a method of using the ultrasonic hairbrush of the present embodiment will be described.
{Circle around (1)} When using the ultrasonic hairbrush according to the present invention, first, when the user turns on the power switch 11, power is supplied from the power supply 10 to the control unit 9.
{Circle around (2)} When the power is supplied to the control unit 9, the set power is supplied from the control unit 9 to the vibration motor 6 and the high-frequency oscillator 7.
{Circle around (3)} The vibration motor 6 receiving the electric power generates mechanical vibration at the set frequency. On the other hand, the high-frequency oscillator 7 receiving the power supplies high-frequency power to the ultrasonic vibrator 8, and the ultrasonic vibrator 8 is excited to generate ultrasonic vibration at a set frequency.
{Circle around (4)} The ultrasonic vibration and the mechanical vibration generated in this way are simultaneously transmitted to the strip 2 via the transmission part 3a of the support part 3 to which the ultrasonic vibration body 8 and the vibration motor 6 are attached.
[0029]
As described above, in a state where the ultrasonic vibration and the mechanical vibration are transmitted to the strip 2, the user grips the grip portion 4 and contacts the strip 2 to the scalp in the same manner as a normal hairbrush. When the strip 2 comes into contact with the scalp in this manner, ultrasonic vibration and mechanical vibration are transmitted from the strip 2 to the scalp. At this time, ultrasonic vibrations and mechanical vibrations are transmitted from the striated body 2 to the scalp. Regarding the ultrasonic vibration, a state in which the striated body 2 holds moisture or a state in which the scalp is wet, for example, When used during bathing in the bathroom, the transmission efficiency of ultrasonic vibration from the striatum 2 to the scalp may be increased. In particular, when used during bathing or during hair washing with shampoo, the ultrasonic vibration is transmitted very well via moisture and shampoo, and the above-mentioned transmission efficiency is improved. Further, in addition to the cleaning action of the shampoo itself, a cleaning action by ultrasonic vibration is obtained, and the cleaning effect is improved. Furthermore, when a drug such as a hair restorer or a hair restorer is applied to the striatum 2 or the scalp and used, the penetration of the drug into the scalp is improved.
[0030]
When the ultrasonic hairbrush is used in this manner, the mechanical vibration and ultrasonic vibration transmitted to the strip 2 are such that the mechanical vibration is a vibration at a relatively low frequency and the ultrasonic vibration is at a high frequency. Therefore, in the depth direction into the scalp, that is, in the Z direction shown in FIG. 4, mechanical vibration is simultaneously applied to the scalp surface layer which is a shallow region having an overlapping region and ultrasonic vibration is a deep region. It is given even inside the scalp.
[0031]
As a result, blood vessels and the like are compressed and relaxed by mechanical vibration, which is vibration at a low frequency, like a massage with a hand or finger in the overlap region. Ultrasonic vibration, which is vibration at a high frequency, is applied to the compressed and relaxed blood vessels and the like, so that the frictional resistance between the blood vessels and the like and the blood and the like is reduced, and the flow of the blood and the like becomes smooth.
[0032]
In the scalp inner layer deeper than the overlapping region, only ultrasonic vibration, which is a vibration at a high frequency, is transmitted. Even outside the overlapping region, the influence of the mechanical vibration and the ultrasonic vibration due to the overlapping region. Receive. In other words, blood and the like that have been compressed and relaxed by mechanical vibration and flowed out from the adjacent scalp surface region flow into the blood vessel or the like to which ultrasonic vibration is applied, and thus friction between the blood vessel and the blood and the like, as described above. The resistance is reduced, and the flow of blood and the like becomes smooth.
[0033]
Further, in the present embodiment, as described above, the striated body 2 vibrates not only in the X and Y directions, which are directions along the surface of the scalp, but also in the Z direction, which is a direction perpendicular to the surface of the scalp. Further, when the user grips the grip portion 4 and combs the hair with the strip 2, the strip 2 is moved in the Y direction shown in FIG. Therefore, during the movement in this direction, the strip 2 moves back and forth in the X and Y directions, which are the radial directions, and the contact width between the scalp and the strip 2 in the X direction is increased. In the Z direction, which is the extending direction of the scalp, the contact pressure of the strip 2 on the scalp is improved by vibration in the same direction. Also, when combing hair with the strip 2, the strip 2 moves smoothly in the Y direction without being attached to the hair by the action of the ultrasonic vibration.
[0034]
As described above, a high massaging effect can be obtained in a wide range due to a synergistic effect of mechanical vibration and ultrasonic vibration.
