Description

[Detailed description of the invention] Purpose of the invention [Industrial field of application] The present invention relates to a high-potential hairbrush, and more particularly to a high-potential hairbrush that has a built-in high-potential generation circuit and is capable of applying a high negative potential to hair, etc. .

[Prior art]

The top of the human head is normally covered with hair (hereinafter referred to as scalp hair), but due to illness, such as high fever or aging, some or sometimes almost all of the hair can be lost or gray. It may become bulky or cause symptoms such as itchiness. In particular, baldness and graying of hair due to hair loss in young and old age,
In addition, alopecia areata, which is often caused by mental problems, can sometimes be seen as old or ridiculed, and the problems that the patients face in their daily lives are sometimes serious. In addition, the excessive amount of scalp buildup not only requires frequent hair care, but also creates an image of uncleanness to those around them, which can sometimes be a burden on the individual.

Therefore, for the purpose of curing these symptoms, various drugs (for administration and application), electrical and mechanical massage devices, and the like have been proposed for a long time.

[Problem that the invention attempts to solve]

However, these drugs and devices have not yet become a fundamental solution, and the development of better treatment devices has been desired.

In addition, in the case of large, stationary electrical and mechanical pine surge devices, commercial power is required, etc.
It was not something that could be used anywhere or anytime. Therefore, in such cases, it is necessary to visit a specialized treatment facility or purchase a large and expensive device, making it difficult to use it continuously.

Therefore, the present inventor aimed to solve the above problem by providing a high-potential hairbrush that is small, easy to handle, and capable of providing high-potential treatment to the head even more effectively. be.

Structure of the invention [Means for solving the problems] This invention, as a means for solving the problems,
The following structure was adopted. That is, the brush part is connected to the handle part through a metal elastic body covered with an insulator, and the handle part has a built-in high potential generation circuit, and the positive electrode of the high potential generation circuit is exposed. However, this is the structure of the high potential hairbrush in which the brush portion is formed with an exposed cathode that is electrically conductive to the high potential generation circuit via the metal elastic body.

Here, the high potential generation circuit is a circuit that can apply a negative high potential to the negative electrode of the brush part based on the potential of the positive electrode of the handle part, and is built in the handle part and/or the brush part. . Various types of circuits are known, including circuits that use dry batteries or rechargeable secondary batteries, such as nickel-cadmium batteries, as a DC power source, and generate high potential from a free-running oscillator and a step-up transformer.

The cathode formed on the brush section applies a negative high potential through the cathode. It may be constructed of conductive rubber or as a wire brush to more effectively apply high potential to the scalp and face.

[Effect]

The high-potential hairbrush of the present invention having such a configuration can be used to brush hair by grasping the handle,
When applying, the positive electrode on the handle is set to a reference potential, and a negative high potential is applied to the scalp etc. via the negative electrode formed on the brush. The metal elastic body that connects the brush part to the handle functions as a conductive path from the positive electrode to the negative electrode, and due to the inherent function of the elastic body, when the brush part is hit against the head etc. With small swings of the handle,
Shake the brush part widely.

The surface of the human body (the stratum corneum) is normally negatively charged, and the dermis is positively charged, but if an abnormality such as a lesion exists in the body or the vitality of the skin declines, the body surface will respond to this charge. A phenomenon occurs when the electrical polarity of the upper part (for example, the so-called acupuncture points) is reversed. The high-voltage hairbrush of the present invention applies a negative high potential to the skin on the head and works to restore the condition to normal.

In fact, based on this knowledge regarding the electric potential of the human body, a treatment called electric potential therapy has been performed for a long time. This is a treatment device that applies a predetermined potential to the human body relative to the potential of the earth's surface, based on epidemiological findings that ``long-term residents living under special high-voltage lines have fewer illnesses and their crops grow better.'' . A direct current type (a negative electrode attached to the human body) high-potential treatment device changes the equipotential point of the constituent proteins in the body fluid, and changes the ratio of the proteins albumin and globulin depending on the polarity of the applied potential. It has been demonstrated that it works to restore normal skin potential to the above-mentioned reversal of skin potential, and is thought to heal the site where the abnormality exists.

The high-potential hairbrush of the present invention has a built-in high-potential generating circuit and can be easily used as a hairbrush on the hair to perform the above-mentioned preventive and curative effects.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a perspective view showing a schematic configuration of an embodiment of the present invention, FIG. 2 is a sectional view thereof, and FIG. 3 is an electric circuit diagram thereof.

In the figure, A indicates a handle portion, and B indicates a brush portion, and the brush portion B is elastically supported by the handle portion A via a metal leaf spring 1.

The handle part A is a case 2 made of synthetic resin.
It is configured by incorporating a high voltage generation circuit 3, etc.
A part of the case 2 is provided with an exposed electrode 5 that functions as a positive electrode. The part where the electrode 5 is installed in a ring shape corresponds to the position where the user holds it during use. The operation of the high voltage generation circuit 3 will be described in detail later, but it operates by receiving power from the third dry battery 7 built in the case 2 via the switch 9, and when activated, the neon lamp Ne1
lights up. The state of the neon lamp Ne1 can be visually checked from the outside through the display window 11, and functions as a pilot lamp.

On the other hand, the brush portion B includes a brush base 20 made of synthetic resin and a brush plate 27 that engages with the flange 23 of the brush base 20 by a locking piece 25. The brush plate 27 is provided with a brush 30 integrally formed of conductive synthetic resin (containing carbon), and when the locking piece 25 is engaged with the flange 23, the brush 30 is attached to the brush base. 2
It is pressed into contact with an electrode 32 formed on the 0 surface and electrically connected.

The leaf spring 1 is covered with an insulating tube 40, and functions as a conductive path from the high voltage generation circuit 3 to the electrode 32.The leaf spring 1 also functions as a conductive path from the high voltage generating circuit 3 to the electrode 32.The leaf spring 1 also functions as the original function of the leaf spring by grasping the handle A and gently pushing the brush part. When brush B is applied to the head, small swings of the handle A cause the brush part B to swing greatly, so that the user can achieve good patching against the head just by shaking the brush lightly. be able to.

Next, the configuration and operation of the high voltage generating circuit 3 will be explained. As shown in FIG. 3, the high voltage generation circuit 3 is constructed as a so-called free-running blocking oscillation circuit, including a transformer T1 for both oscillation and boosting, and an oscillation transistor Tr1. In the figure,
R1 is a resistor that limits the base current of transistor Tr1, D1 is a diode that works as a rectifier in the output circuit of transformer T1, and Ne1 is a neon light that lights up when the high voltage generation circuit 3 is in operation and can be seen from the outside. The lamp R1 is a protective resistor. The transformer T1 is a secondary transformer with a turns ratio of about 200, and the positive side of the dry cell battery 7 is connected to the intermediate tap of the primary coil, and one end of the coil is connected to the transistor Tr1 via the resistor R1.
, and the other end is connected to the collector of the transistor Tr1, and the emitter of the transistor Tr1 is connected to the negative side of the dry battery 7 via the contact of the switch 9. The primary circuit is approximately 2
It oscillates at ~3KHz, and a maximum voltage of about 400V is generated on the secondary side of transformer T1.

Therefore, when a user picks up the high-voltage hairbrush of this embodiment and grasps the handle A to comb or pat hair, the user's palm naturally touches the handle A.
On the other hand, the brush 30 made of conductive synthetic resin is held by the leaf spring 1 and the electrode 3.
Since the transformer T1 is electrically connected to the high voltage generating circuit 3 through the transformer T1, the high voltage generated on the secondary side of the transformer T1 is applied to the head, mainly the scalp. Of course, since the neon tube Ne1, protective resistor R1, and rectifier diode D1 are connected in series in the closed circuit on the secondary side, even if the human body resistance has decreased considerably due to sweat etc. Since only a small amount of direct current flows, there are no safety issues.

Since this current is rectified by the diode D1, if the electrode 5 of the handle A is set to a reference potential, a negative high potential will be applied to the hair/scalp that is being brushed or patted by the high potential hairbrush. It has the effect of maintaining or restoring the scalp surface potential to normal. Therefore, it is possible to prevent hair loss, promote hair growth, suppress scalp buildup, etc.

In addition, in the high potential hairbrush of this embodiment, the brush portion B is elastically supported via the plate spring 1, so that together with the tucking effect, the above-mentioned effects such as promoting hair growth can be further enhanced. Furthermore, the high-potential hairbrush of this embodiment uses a small dry battery 7 as a power source.
Since it is possible to perform high-potential treatment without using a commercial power source, it is possible to use it at any time.
It has the advantage of being able to be used anywhere, and the above effects can be made more reliable through continued and repeated use. In addition, the brush part B of this high-potential hairbrush has a brush base 2.
Since the brush plate 27 on which the brush 30 is provided can be removed from the brush 0, it is easy to perform cleaning and other maintenance, and it is also easy to keep the brush 30 clean. Further, during use, the neon tube Ne1 lights up in response to the current flowing to the secondary side of the transformer T1, and this can be visually recognized, so that it is possible to easily know whether the dry cell battery 7 is depleted.

In the above embodiments, a normal dry cell battery is used as the power source, and a free-running oscillator circuit and a step-up transformer are used to generate high voltage. However, any step-up circuit can be used; for example, a multi-layer The high potential generation circuit may be directly constructed using a lithium dry cell or the like having a high electromotive voltage. Further, instead of the dry cell battery 7, a rechargeable battery that is charged by a commercial power source may be used. In these embodiments, the brush base 20 and the brush plate 27 are configured to be detachable, but it is also possible to form both parts integrally to simplify the configuration and reduce manufacturing costs. Further, in these embodiments, the brush 30 that is pressed against the electrode 32 of the brush portion is formed using a conductive synthetic resin, but the brush itself can also be used directly as an electrode, such as a wire brush, for example.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment in any way. For example, a coil spring is used instead of a plate spring and an electric wire is laid inside the spring, or a brush 30 is used instead of a plate spring. It can be implemented in various ways, such as a configuration in which a sponge ball or the like made of a conductive material is provided to effectively perform brushing with the brush 30 and patting with the sponge ball.

FIG. 4A is a perspective view showing the structure of such a sponge ball portion, and FIG. 4B is a sectional view taken along the line A-A'. The sponge ball portion includes a sponge ball 70 formed into a gently convex shape made of urethane mixed with carbon, silver powder, etc. to give conductivity, and is provided on a mounting plate 72, and a locking piece 75
(3 locations) to be locked to the brush base 20 in the above-described embodiment. At this time, a high negative potential is applied to the sponge ball 70 via the electrode 32, and this is applied to the scalp or face by patting to bring out even more effects.

Effects of the Invention As detailed above, the high-potential hairbrush of the present invention connects the brush part to the handle part through a metal elastic body covered with an insulator, and has a high-potential generation circuit built into the handle part. In addition, the positive electrode of the high potential generation circuit is formed to be exposed, and the brush portion is formed to have an exposed negative electrode that is electrically conductive to the high potential generation circuit through a metal elastic body.

Therefore, when a user grips the handle and brushes hair or pats the scalp, the user's palm naturally grips the positive electrode, and the negative electrode of the brush part applies a high potential on the negative side to the scalp, etc. applied. Therefore, since it has the effect of maintaining or restoring the potential of the skin surface such as the scalp to normal, effects such as preventing hair loss, promoting hair growth, and suppressing scalp scale can be obtained. In particular, the high-potential hairbrush of the present invention has a built-in high-potential generation circuit and is compact and portable, so it can be used anytime and anywhere. Due to the natural function of the elastic metal body, which is also a road, by grasping the handle part and hitting the brush part little by little on the head, etc., it is possible to achieve good patching, making the above effects even more reliable and effective. It is an excellent product that can be obtained effectively.
