<First Embodiment>
FIG. 1 is a diagram showing an example of a hairbrush according to the first embodiment. Further, FIG. 2 is a top view of the hairbrush according to the present embodiment as viewed from above. As shown in the figure, the hairbrush 100 includes a handle 101 and a head 102. The handle 101 is a part of a handle to be gripped when using the hairbrush 100. The handle 101 is made of, for example, plastic resin or wood.

The head 102 is provided by being connected to the handle 101, and is a portion used so as to apply brush hair toward the hair or skin of a person or animal at the time of use. Specifically, the head 102 includes a base portion 102a and a support portion 102b fitted in the base portion.

FIG. 3 is a cross-sectional view of the AA'line cross section of the hairbrush shown in FIG. 2 as viewed from the direction indicated by the arrow. As shown in FIG. 3, the base portion 102a is provided with an opening O on one side, and the support portion 102b is fitted and fixed therein. The support portion 102b is a dome-shaped support member that supports the brush bristles to be transplanted, and has a plurality of soft brush bristles 103 in which the tip end side of the wire wire is curved in a ring (closed loop) shape and a metal brush bristles 104. It penetrates and is fixed on the back side.

In this embodiment, the soft brush bristles 103 are arranged in five rows in the longitudinal direction, and the metal brush bristles 104 are arranged in four rows so as to fill the space between them. The arrangement of each brush is not necessarily limited to this, but in order for the user to get the feel of the soft brush bristles 103 before the metal brush bristles 104 reach the scalp, the soft brush bristles 103 are surrounded by the metal brush bristles 104. Is desirable. Further, it is desirable that the number of metal brush bristles 104 occupies 1/2 or more of the number of soft brush bristles 103. Although the handle 101 and the base 102a are integrally formed in the present embodiment, they may be formed separately and combined.

The soft brush bristles 103 are formed of, for example, a nylon wire rod in a ring shape, and have a predetermined height (for example, 10 to 50 mm, preferably 10 to 50 mm, preferably 10 to 50 mm) in a direction substantially upright with respect to the dome-shaped curved surface of the support portion 102b. It is fixed so as to stand up at (15 mm to 45 mm). The wire diameter is a predetermined thickness (for example, 0.1 to 2.0 mm, preferably 0.3 mm to 1.5 mm). As the material, for example, a chemical resin wire rod, an animal wire rod, a plant wire rod, or the like can be used, and both ends can be welded or bound and then bonded to the support portion 102b. Regardless of the material used, it is desirable that the metal brush bristles 104 are formed to have lower rigidity and softness than the soft brush bristles 103 and to be easily bent.

The metal brush bristles 104 are formed of, for example, a metal wire in a ring shape, and have a predetermined height (for example, 5 to 45 mm, preferably 5 to 45 mm, preferably 5 to 45 mm, in a direction substantially upright with respect to the dome-shaped curved surface of the support portion 102b. It is fixed so that it stands up at 10 to 40 mm). The wire diameter is a predetermined thickness (for example, 0.3 to 1.5 mm, preferably 0.5 mm to 2.0 mm). The metal brush bristles 104 are formed by using a conductive metal material such as gold, platinum, copper, copper alloy, zinc, titanium, aluminum, and stainless steel. The material is not limited to this as long as it has a conductive material, and a plated material having a metal plating or the like on the surface, a conductive rubber material, or the like may be used. Further, regardless of the material used, it is desirable that the metal brush bristles 104 are formed to have a moderately higher rigidity than the soft brush bristles 103.

Further, as shown in FIG. 3, in the soft brush bristles 103 and the metal brush bristles 104, the height of the support portion 102b from the surface is higher in the soft brush bristles 103 and lower in the metal brush bristles 104. ing. As a result, when the user uses the brush, the apex T of the long soft brush bristles 102a first comes into contact with the skin (scalp, etc.), and then is softened by the degree of pressing force (hereinafter referred to as brushing pressure). When the brush bristles 102a bend, the apex T of the short metal brush bristles 104 reaches the skin. Further increasing the brushing pressure causes the metal brush bristles 104 to bend, resulting in stronger stimulation. It should be noted that not all brush bristles of the same type do not necessarily have the same height. If the soft brush bristles 103 have a structure higher than the metal brush bristles 104 and come into contact with the skin first, they can be freely designed.

The fixing and arrangement of the soft brush bristles 103 and the metal brush bristles 104 are not necessarily limited to the present embodiment, but can be carried out by, for example, the following methods. FIG. 4 is an explanatory diagram showing a method of fixing each brush bristles to the support portion 102b. According to such a method, a through hole is provided in the support portion 102b, and the loop-shaped soft brush bristles 103 and the metal brush bristles 104 are inserted from the back side into the through holes, or fixed by welding, adhesion, or the like. Specifically, for example, an elastic rubber material is used for the support portion 102b, and the through hole is provided small enough to allow the loop-shaped wire of the brush bristles to pass through. The loop-shaped soft brush bristles 103 and the metal brush bristles 104 are press-fitted there from the back side and fixed near the root by utilizing the shrinkage property of the rubber material of the support portion 102b, so that they can be easily attached.

Further, for the support portion 102b, for example, a flat material can be used. In that case, the support portion 102b is formed larger than the peripheral edge of the base portion 102a in advance, the loop-shaped soft brush bristles 103 and the metal brush bristles 104 are planted, and then fitted into the opening O of the base portion 102b to form a dome shape. May be. By forming the edge of the base portion 102b into a shape that is hollowed out inward, fitting becomes easy. The plate thickness of the support portion 102b at that time is, for example, 2 mm to 7 mm, preferably 2 mm to 5 mm. Further, when the hair is transplanted to the support portion 102b of the loop-shaped soft brush hair 103 and the metal brush hair 104, the hair can be transplanted at the same time as making a hole by directly driving the brush hair or the like.
Further, for example, when the end portion of the metal brush bristles 104 is fitted into the support portion 102b of the rubber material and the bristles are planted, even if the tip portion of the metal brush bristles 104 is pressed with a strong force, the end portion of the metal brush bristles 104 remains. Since the metal brush bristles 104 are pressed by the support portion 102b of the rubber material, the rubber, which is an elastic material, is deformed and the end portion can be tilted sideways to support the metal brush bristles 104 without bending.

Further, it is not always necessary to use one brush bristle in one through hole, and two or more wires may be fixed in one through hole. FIG. 5 shows an example in which the soft brush bristles 103 and the metal brush bristles 104 are fixed together in one through hole. By changing the flocking density in this way, it is possible to design brushes with various usability. Further, although not shown in the figure, the loop-shaped soft brush bristles 103 and the metal brush bristles 104 may be a plurality of loops, and the tip of the loop may be a plurality of forks.

Further, as shown in FIGS. 6 (a) and 6 (b), the brush bristles may be formed of a protruding member or a pin-shaped member instead of a wire rod. FIG. 6A is an explanatory view when the soft brush bristles 103a formed of the protruding member are provided. As shown in FIG. 6A, here, the soft brush bristles 103a are formed of a protruding member, which can be integrally molded with, for example, the support portion 102b. Of course, a method may be used in which the protruding member is penetrated from the back side of the support portion 102b and fitted.

FIG. 6B is an explanatory diagram in the case where a soft brush bristles 103a formed of a protruding member and a metal brush bristles 104a formed of a pin-shaped member are provided. As shown in FIG. 6B, here, the metal brush bristles 104a are further formed of a pin-shaped member. For such a pin-shaped member, for example, a metal or a conductive material can be used. Further, in the metal brush bristles 104a, the end portion on the side touching the skin is rounded to improve the skin contact, and the hemispherical head H is formed on the other end portion. As a result, when the brush bristles 104a are penetrated from the back side of the support portion 102b, the head H can be caught on the back side surface of the support portion 102b and fixed.

FIG. 6C is an explanatory diagram when an oscillator is provided at the end of the metal brush bristles. As shown in FIG. 6C, an oscillator 106 made of ceramic or the like may be provided on the back surface of the base portion 102b to which the end portion of the metal brush bristles 104 is fixed. As a result, vibration is transmitted to the skin via the metal brush 104, and further massage effect can be expected. Further, for example, a non-flocked through hole may be formed in the support portion 102b (for example, every other brush bristles) to emit light from this hole. Further, the brush bristles can be formed by an optical fiber to guide the light. The light is not limited to monochromatic light, and the color may be changed after a while, or the light may be blinked by using pulsed light or the like.

As described above, by forming the soft brush bristles with the protruding member or the metal brush bristles with the pin-shaped member, the strength can be higher and the hair can be made to last longer. In addition, it is possible to manufacture a hairbrush that is closer to the user's favorite feeling of use.

The first embodiment of the present invention has been described above. According to the hairbrush of the present embodiment, by using brush bristles made of two different materials, it is possible to adjust a delicate stimulus feeling that cannot be obtained with only one brush. That is, since the soft soft brush bristles 103 first come into contact with the skin and then the hard metal brush bristles 104 come into contact with each other, the user can gradually obtain the desired intensity of stimulation. In particular, when the skin is weak or scratched, the irritation may be too strong if a hard brush suddenly hits the skin. However, according to the hairbrush 100 of the present embodiment, since the soft brush bristles 103 first come into contact with the skin, the user can brush with confidence while adjusting the stimulus. On the other hand, when strong irritation is desired, the brushing pressure is gradually increased so that the metal brush bristles 104a come into contact with the skin, and the irritation can be obtained safely and appropriately.

Even in the case of thinning hair, short hair, or hairlessness, it is possible to sufficiently obtain stimulation. Further, the above-mentioned effect can be expected not only on the head but also on the face, neck, mold, back, arms, legs and the like other than the head. Of course, it may be used for animals.

Further, since the soft brush bristles 103 come into contact with the skin prior to the metal brush bristles 104, the metal brush bristles 104 are less likely to bend or sag than when used alone, and last longer.

In addition, some metals have antibacterial activity against microorganisms, and silver, copper, zinc and the like have been known for a long time. Furthermore, in recent years, research on antiviral activity has been progressing, and it has been reported that when influenza A virus comes into contact with the surface of copper (C1020), it is almost killed in about 30 minutes. It is also known to have an infectious inactivating effect on the new coronavirus. Due to such antibacterial and antiviral effects, the metal brush bristles 104 can keep the skin healthy by killing bacteria in the skin and hair and inactivating the virus.

<Second embodiment>
FIG. 7 is a top view of the hairbrush according to the present embodiment as viewed from above. FIG. 8 is a cross-sectional view of the AA'line cross section of the hairbrush shown in FIG. 7 as viewed from the direction indicated by the arrow. The hairbrush 200 includes a handle 101 and a head 102, similar to the hairbrush 100 of the first embodiment. In the subsequent embodiments including the present embodiment, the same configurations as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

The metal brush bristles 204 are composed of a first electrode brush bristles 204a and a second electrode brush bristles 204b, which are different metals from each other. Specifically, for the first electrode brush bristles 204a, a metal having a lower ionization tendency than the metal selected by the second electrode brush 204b, for example, gold, platinum, silver or copper, is used, and the second electrode brush bristles are used. For 204b, a material having a higher ionization tendency than the metal selected in the first electrode brush bristles 204a, for example, zinc, titanium, aluminum, tungsten, stainless steel, silver or copper, is used. The substance that can be used as the electrode brush bristles is not limited to metal. Any combination may be used as long as it can generate a weak current in the living body by utilizing the difference in potential difference (ionization tendency). For example, it is not limited to dissimilar metals, and a conductive polymer, a conductive oxide, or the like may be combined. Further, it may be called a semiconductor.

Further, the first electrode brush bristles 204a and the second electrode brush bristles 204b are electrically connected to each other by the conductive portion 210 on the back side of the support portion 102b. The conductive portion 210 is here the wiring 205, and the wiring 205 is made of a material containing a substance having conductivity. For example, a metal, a material mainly containing carbon, a resin rubber having conductivity, and the like.

Further, in the present embodiment, the first electrode brush bristles 204a and the second electrode brush bristles 204b are alternately arranged in the four rows of the metal brush bristles 204. However, the present invention is not limited to this, and any arrangement may be used as long as both brush bristles tied by the conductive portion 210 are in contact with the skin at the same time. Further, it is desirable that a predetermined space is provided between the first electrode brush bristles 204a and the second electrode brush bristles 204b so that they do not come into contact with each other and cause a short circuit. Further, for example, the second electrode brush bristles 204b and the first electrode brush bristles 204a may be connected by using a conductive rubber material for the support portion 102b.

In such a hairbrush 200, since the first electrode brush bristles 204a and the second electrode brush bristles 204b have a potential difference, when they hit the skin during use, they form an electrically closed circuit between both electrodes and the skin. A weak electric current can be passed through the living body. Specifically, a part of the body (for example, the scalp) to which the first electrode brush bristles 204a and the second electrode brush bristles 204b are in contact plays the role of an electrolyte in the battery, and one electrode brush (here, the negative electrode brush) functions as a negative electrode. , 2nd electrode brush bristles 204b), positive ions are ionized, and electrons move to the other electrode brush bristles (here, 1st electrode brush bristles 204a) that function as a positive electrode, and both electrode brush bristles. A potential difference occurs in. Due to this potential difference, a weak current flows in the living body. The weak current varies depending on the condition of the skin surface, the external environment (temperature, humidity, etc.), the pressing strength, and the like, but is, for example, 0.1 μA to 50 μA, preferably 0.3 μA to 20 μA. The voltage generated between the two poles is, for example, 100 mV to 3 V, preferably 200 mV to 2.6 V.

Further, as shown in FIGS. 9 (a) and 9 (b), the brush bristles may be formed of a protruding member or a pin-shaped member instead of a wire, and both may be connected. FIG. 9A is an explanatory diagram when the metal brush bristles are directly contacted and connected to each other. As shown in FIG. 9A, the ends (referred to as conductive portions 210a) of the adjacent first electrode brush bristles 204a and the second electrode brush bristles 204b are joined to each other on the back surface of the support portion 102b. , Two metal brush bristles 204 that function as electrodes can be electrically connected to each other.

9 (b) and 9 (c) are explanatory views in the case of connecting metal brush bristles formed of pin-shaped members. As shown in FIG. 9 (b), when the metal brush bristles are formed of a pin-shaped member, metal or metal is formed between the back surface of the support portion 102b and the head H of adjacent electrode brush bristles having different potentials. By sandwiching the conductive portion 210b, which is a thin piece formed of a conductive rubber material or the like, both electrode brushes 104a can be electrically connected to each other. Further, as shown in FIG. 9C, a structure may be provided in which a conductive portion 210c for connecting the heads of the metal brush bristles 104a with a conductive member is provided.

FIG. 9D is an explanatory diagram when the soft brush bristles are formed of a conductive rubber material to form the first electrode brush bristles and the metal brush bristles are provided as the second electrode brushes. As shown in FIG. 9D, the soft brush bristles may be provided as the first electrode brush bristles 204e, and the metal brush bristles may be provided as the second electrode brush 204b (the second electrode brush bristles may be pin type). The first electrode brush bristles 204e contain, for example, powders such as carbon, silver, copper, and titanium, and have a potential difference from the second electrode brush bristles.

According to such a configuration, it is possible to energize only when both brush bristles are pressed by the brushing pressure due to the difference in height of the electrode brush bristles. In addition, various stimuli can be given by changing the shape of the brush bristles.

The present embodiment has been described above. According to the present embodiment, the weak current generated by the hair brush enters the dermis layer of the skin without damaging the tissue on the surface of the skin, arranges the ion arrangement of the cell tissue of the body, and has a cosmetic effect on the skin. If you work on the acupuncture points, you can activate the biological activity of the human body, and you can expect the healing and preventive effects of the disease. At the same time, the antibacterial and antiviral effects of metal materials can keep the skin healthy.

FIG. 10 is an explanatory diagram showing a first modification of the hairbrush according to the present embodiment. As shown in the figure, the hairbrush 300 includes a metal brush bristles 104, a wiring 305 in a conductive portion 310, and a current generating portion 306. The current generation unit 306 is, for example, a battery as a power source for generating current, or a circuit including the battery. Each of the metal brush hairs 104 is connected to the negative electrode or the positive electrode of the current generating portion 306 by the wiring 305, respectively. Here, for example, it is assumed that the metal brush hairs 104 in the first and third rows from the left side of FIG. 10 are connected to the negative electrode, and the metal brush hairs 104 in the second and fourth rows are connected to the positive electrode. As a result, when the hairbrush 300 is used, an electric current flows into the living body and activates the biological activity.

The battery included in the current generating unit 306 may be a secondary battery or a solar cell. Further, the wiring 305 connecting the metal brush bristles 104 does not necessarily have to be as described above, and is free as long as the metal brush bristles 104 connected to the positive electrode or the negative electrode are in contact with the skin or hair at the same time during use. Can be designed to.

Further, a switch for temporarily disconnecting the wiring 305 may be provided. This makes it possible for the user to prevent excessive current from flowing during use. Further, a current limiting diode or a resistor for controlling the amount of current may be provided. Further, when the current amount is controlled by a current limiting diode or a resistor, the current amount can be controlled by connecting a control circuit provided with them.

FIG. 11 is an explanatory diagram showing a second modification of the hairbrush according to the present embodiment. As shown in the figure, the hairbrush 400 is provided with a conductive sheet 407 on the outer surface of the base 102a, and an electric current can be passed from the user's finger into the living body. Specifically, the conductive portion 410 of the hairbrush 400 includes a wiring 405, a current generating portion 306, and a conductive sheet 407. The wiring 405 connects each metal brush bristles 104 and the current generating section 306, and also connects the current generating section 306 to the conductive sheet 407. The conductive sheet 407 is, for example, a conductive rubber material, and is provided on the outside of the base 102a.

An example of using the hairbrush 400 will be described. FIG. 12 is an explanatory diagram showing an example when the hairbrush according to the present modification is used. The user uses the hairbrush 400 with the handle 101 grasped and the finger placed on the conductive sheet 407. Then, the current generated from the current generating unit 406 is transmitted to the user's finger via the conductive sheet 407. After that, the current flows through the user's body (arms, neck, face, head, etc.), is transmitted to each electrode brush 404, and returns to the current generation unit 406 again. As described above, according to the present embodiment, the electric current is transmitted over a long distance from the hand, and the biological activity of more parts can be activated.

Even with such an electrode cleaning tool, a weak electric current can be passed through the skin of the animal in contact with the first electrode portion and the second electrode portion, and the effect of activating the skin can be expected. In addition, an antibacterial effect can be expected.

In the above modification, the current generated by the current generating unit 306 is not limited to direct current, but may be alternating current such as a pulse wave. Further, it may be a low frequency, a high frequency, or a synthetic wave in which these are combined. For example, low frequency refers to a frequency range of 0.2 Hz to 1.2 KHz, and high frequency refers to a frequency range higher than low frequency, that is, higher than 1.2 KHz and up to several hundred KHz. Here, a high frequency (continuous wave, pulse wave) of preferably 2 KHz to 20 KHz, more preferably 4 KHz to 11 KHz is used. In some cases, 1 KHz or less is defined as a low frequency, 1 KHz to 10 KHz is defined as a medium frequency, and 10 KHz or more is defined as a high frequency. In this case, the medium frequency pulse may be superimposed on the low frequency base wave, or the high frequency pulse may be superimposed on the low frequency basis wave.

Further, the waveform may be a waveform obtained by superimposing a pulse wave on the upper end of a low frequency base wave. The waveform may have at least a portion of the rise and fall in the period of the waveform slowly rising or falling. The amplitude of the pulse wave fluctuates periodically, and the fluctuation period of the amplitude may be larger or smaller than the period of the base wave.

It is generally said that there is a potential difference of several tens of millivolts (about 70 millivolts) between the inside of each cell membrane and the outside, and that the skin potential is involved in various biological activities. Furthermore, in recent years, it is thought that the skin has information processing ability comparable to that of the brain and senses many sensations due to its prominent area. The skin and brain are originally differentiated from the same ectoderm, and it is known that the surface potential changes depending on emotions and moods by sensing ultrasonic waves and low-frequency sounds that cannot be heard by the ear, as well as light and color. In this way, the skin is thought to act as a receptor for electric potential, electric current, sound and light, tactile sensation, vibration, hormones, neuropeptides, etc., so that it is called the second and third brains. Therefore, voice, music, and their overtones may be used as the current. It is thought that this will further activate the living body and obtain a high massage and relaxing effect.
