BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a view showing the structure of tourmaline 1 according to a first embodiment of the present invention, wherein FIG. 1 (A) is a plan view and FIG. 1 (B) is a front sectional view.

As shown in FIG. 1, tourmaline 1 is composed of a base 11 made of an insulator, and a positive electrode 12 and a negative electrode 13 provided so that the surface is exposed to the base 11. .

Tourmaline 鹼 1 is large enough to be grasped by hand as a whole, and its surface is composed of smooth flat surfaces and curved surfaces as a whole. The base 11 and the positive electrode 12 are provided as a pair on each side of the base 11.

The base body 11 is formed in a substantially disc shape, and has a hole 31 for weight reduction at the center. The base 11 also has a recess for fitting the positive electrode 12 and the negative electrode 13.

As the material of the substrate 11, a calcium cement type, an oxychloride cement type, a hydroxyapatite type, a magnesia cement, or the like is used. When a calcium-based material 3 is used, calcium is ionized and dissolved in water, and ionically bonds with magnesium precipitated from the negative electrode 13 to be absorbed from the skin. Retention and activation are achieved. It is also possible to use ceramics, synthetic resin, or the like as the material of the base 11.

The positive electrode 12 and the negative electrode 13 are arranged so as not to be in contact with each other. It is insulated from the air. They are also arranged so that they can be in simultaneous contact with the skin when used by humans. The negative electrode 13 has a disk shape in plan view, and the positive electrode 12 has a ring plate shape surrounding the negative electrode 13.

As a material of the positive electrode 12, a noble metal in the dissimilar metal contact corrosion is used, and as a material of the negative electrode 13, a noble metal in the dissimilar metal contact corrosion is used. That is, the potential of a metal in seawater differs depending on the type of metal. When dissimilar metals with different potentials are electrically coupled in seawater, the lower potential, that is, the noble metal becomes the negative electrode (anode), and the higher potential, that is, the noble metal becomes the positive electrode (force sword). A local battery is formed. This is called galvanic corrosion.

Generally, graphite, platinum, nickel-chromium-molybdenum alloy C, titanium, nickel-chromium-copper-silicon alloy B, nickel-iron-chromium alloy 825, alloy 10, stainless steel, etc. are precious metals. . Graphite and platinum exhibit a potential of about +0.2 volts. Other metals show potentials near zero port.

Magnesium, zinc, beryllium, aluminum alloys, etc. are also base metals. Magnesium has a potential of about -1.6 volts, and zinc, beryllium, aluminum alloys, etc. have a potential of about -1.0 volts.

Corrosion of lower metals is accelerated by contact with noble metals. Also, the corrosion rate of the noble metal used as the negative electrode increases as the area of the noble metal used as the positive electrode increases. When the ratio of the area of the cathode to the area of the cathode is small, the depth of corrosion of the cathode is increased. The critical potential for hydrogen absorption of a metal such as titanium is about 0.75 volts (SCE). By maintaining the anticorrosion potential at a potential nobler than the critical potential, for example, 10.6 volts, Hydrogen absorption phenomenon can be prevented.

In the present embodiment, carbon (carbon) is used as the material of the positive electrode 12. Magnesium is used as the material of the negative electrode 13. In another embodiment, platinum (platinum) can be used as the material of the positive electrode 12.

The tourmaline 鹼 1 configured as above is used as follows.

That is, when the surface of tourmaline 1 is dry (not wet), P There is no potential difference between the positive electrode 12 and the negative electrode 13, and no current flows. However, when the surface of the electric experiment 1 is wetted with water or an aqueous solution, a galvanic battery is formed by the positive electrode 12 and the negative electrode 13, and a large electromotive force of 1.5 port or more can be obtained ( See Figure 14).

In other words, by using tourmaline 1 together with water or a small amount of detergent, the dissolved oxygen in the liquid or the movement of the solution due to the rubbing action causes the outside air to be mixed and diffused and dissolved on the surface active surface. However, the diffusion of oxygen on the aqueous surface by the gaseous action that is the sum of the dissolved oxygen in the liquid forms an electrical connection using the water liquid as the conductive path at the polarities of the two dissimilar metals. An internal current flows through the electrodes 12 to form a galvanic battery in which the positive electrode 12 is positive and the negative electrode 13 is negative.

By moving the tourmaline 1 or rubbing the skin, the solution is agitated, polarization is promoted, and the current effect is increased.

Further, the use of tourmaline 1 causes magnesium to precipitate at the grain boundary from the cathode 13, causing ionization and polarization of magnesium, and the water-soluble silica component is applied to the surface of the skin or keratin epidermis, which is the cleaning surface. It reacts actively due to the coagulation effect, and activates the skin through silica cross-linking, ion reduction, and ion redeployment.

In addition, since bacteria existing in a living body are killed by receiving a voltage of about 5 volts, whether or not the tourmaline 1 is moved while the positive electrode 12 and the negative electrode 13 are in contact with human skin Or by rubbing, the surface of the skin is sterilized or sterilized. Therefore, it has an odor-preventing effect to prevent odors caused by the propagation of bacteria. Also, in that case, there is no need to use a large amount of soap as in the past, so that a large amount of foam is not generated.

In addition, when using tourmaline 鹼 1, a large amount of fine bubbles are generated, but the generated bubbles are subjected to an electric field treatment by an electric field generated by a galvanic battery, so that they are easily decomposed and reduce the amount of bubbles. There is no large amount of foam left when flowing.

In tourmaline 1, the size relationship between the positive electrode 12 and the negative electrode 13 affects the polarization action. In other words, the following characteristics and applications depend on the size of the area. There are differences.

(1) When the area of positive electrode 1 is larger than the area of negative electrode 13

In the electrokinetic effect of the positive electrode 12 mainly based on the positive polarization action, sterilization by redox, sterilization, or cation decomposition is performed. As a result, the deodorizing and deodorizing effects are great. In addition, there is an astrinsen effect that is advantageous for keeping the stratum corneum on the skin acidic.

(2) When the area of anode 12 is smaller than the area of cathode 13

Grain boundary precipitation of magnesium on the cathode 13 is promoted. It excites the ionization spread of magnesium and calcium due to the transfer of charges from water quality transition elements, works to preserve the epidermis and skin of the skin, and is effective in responding to wet modification.

(3) When the area of the positive electrode 1 2 is the same as the area of the negative electrode 13

The polarization width is maximized, and a large potential difference is obtained. The main purpose is the electrokinetic effect in the electric field on the hands, palms, feet, soles, etc.

If only conventional stones and other surfactants are used, symptoms such as dermatitis and cracks may appear on the skin of the hands, etc. Although no consideration has been given to the disposal of these, when tourmaline 鹼 1 is used, the balance between magnesium and calcium is adjusted together with skin washing, and aftercare is performed.

Next, another embodiment of tourmaline II will be described.

FIG. 1 is a diagram showing the structure of tourmaline 1B according to the first embodiment of the present invention, FIG. 2 (A) is a plan view, and FIG. 2 (B) is a front sectional view. The same applies hereinafter.

As shown in FIG. 2, tourmaline 1 B includes base 11, positive electrode 12, and negative electrode 13. These materials, arrangement, and function are the same as those of the electromagnet 1 of the first embodiment described above.

The tourmaline 1B, like the tournament 1, has a size that can be grasped by hand as a whole, and its surface is entirely composed of smooth flat surfaces and curved surfaces. The base 11 is formed in a substantially disk shape with a circular shape in plan view and a bulged central portion. Therefore, each of the positive electrode 12 and the negative electrode 13 is formed on a curved surface.

FIG. 3 is a view showing a structure of tourmaline 1C according to a third embodiment of the present invention.

The basic configuration of tourmaline 鹼 1C shown in FIG. 3 is the same as that of tourniquet 1B described above. is there. In tourmaline 鹼 1C, each of the positive electrodes 12 having a circular outer surface is provided with four circular holes, and each hole is provided with a small circular negative electrode through the base body 11. 13 is fitted.

FIG. 4 is a view showing a structure of tourmaline 1D according to a fourth embodiment of the present invention.

The basic structure of the electric stone 1D shown in FIG. 4 is the same as that of the electric stone 1C described above. In the electric experiment 1D, the anode 13 having a circular curved surface is fitted on both sides of the anode 12 as a base or a base through the base 11.

FIG. 5 is a view showing the outer shapes of tourmaline 1E to G of the fifth to seventh embodiments of the present invention.

Although not shown in the figure, the front and back are the same.

FIG. 6 is a diagram showing a circuit of a tourmaline 1 H according to an eighth embodiment of the present invention.

In the tourmaline 鹼 1 H, the structure, shape and the like may be any of the tourmaline 鹼 1 to 1 G described above. In tourmaline 1 H, a series body of resistors R 1, R 2 and capacitor C D 1 is connected between positive electrode 12 and negative electrode 13. The capacitor C D 1 has a capacitance of about 0.1; U F and a withstand voltage of about 5 ports. The resistances R 1 and R 2 are both about 30 Ω.

Electricity from the galvanic battery formed by the positive electrode 12 and the negative electrode 13 is stored in the capacitor C D1. Resistors R 1 and R 2 prevent excessive current. The values of the capacitance of the capacitor C D1 and the resistances R 1 and R 2 may be other than those described above. It is also possible to omit one of the resistors Rl and R2.

FIG. 7 is a view showing an outer shape of a toothbrush 2 according to a ninth embodiment of the present invention. 7 (A) is a plan view, FIG. 7 (B) is a front view, and FIG. 7 (C) is a bottom view. As shown in FIG. 7, the toothbrush 2 includes a grip 21 made of an insulator, a number of filaments FM provided at the tip of the grip 21, and a positive electrode 2 provided on the upper surface of the grip 21. 2 and a negative electrode 23.

The grip 21 is made of the same material as the base 11 described above. In addition to being a handle for fulfilling the above function, it is also a base supporting the positive electrode 22 and the negative electrode 23.

The positive electrode 11 and the negative electrode 13 are made of the same material as the positive electrode 12 and the negative electrode 13 described above, and perform the same function. In other words, a galvanic battery is formed between them.

In particular, by using magnesium as the material of the negative electrode 23, a large electromotive force of about 1.5 ports can be obtained, thereby exhibiting a strong sterilizing effect.

The positive electrode 22 is arranged so that the hand contacts the positive electrode 22 when the grip portion 21 is held by hand for use of the toothbrush 2. The negative electrode 23 is disposed on the tip side of the positive electrode 22 and comes into contact with the solution in the oral cavity.

By brushing the teeth with water or an aqueous solution using a toothbrush 2, the same cleaning, sterilization, and sterilization as in the case of tourmaline 1 are performed in the oral cavity, which has the effect of deodorization and deodorization, and prevents bad breath. You.

In other words, daily brushing is a kind of cleaning action, so conventional toothbrushes have the main purpose and effect of cleaning teeth and polishing the teeth, and cannot expect the effect of disinfection or sterilization in the oral cavity. . However, by using the toothbrush 2 of the present embodiment, there is an effect of sterilization and sterilization, and the cleaning is performed more clearly.

FIG. 8 is a view showing an outer shape of a toothbrush 2B according to a tenth embodiment of the present invention.

As shown in the figure, the anode 22B is reciprocated in the horizontal direction with respect to the polished surface in contact with the filament FM while holding the anode 22B by hand. Thereby, cleaning, sterilization or sterilization of the oral cavity is performed.

FIG. 9 is a front sectional view of the shaving apparatus 3 according to the eleventh embodiment of the present invention, FIG. 10 is a view of the blade 3 2 of the shaving apparatus 3 viewed from the front, and FIG. Fig. 12 shows an example of the arrangement of the positive electrode 32 and the negative electrode 33. Fig. 13 shows the arrangement of the positive electrode 32 and the negative electrode 33. Fig. 13 shows the shaving with the shaving device 3. It is a figure for explaining a state of hair. As shown in FIG. 9, the shaving apparatus 3 includes a shaving apparatus body 3 made of an insulator, a blade EG that is also used as a positive electrode 32 provided on the shaving apparatus body 31 and an EG, and a shaving apparatus body. The guide part 31 comprises a negative electrode 33 provided at the tip of the GD.

The shaver body 31 is made of the same material as the base 11 described above, is a handle for performing the function of the shaver 3, and supports the positive electrode 32 and the negative electrode 33. It is also a substrate.

The positive electrode 32 is a stainless steel material, and is hardly electrically polarized in an underwater system. In other words, the diffusion of water-based dissolved oxygen on the metal surface is slow, and it has a non-corrosive property that is passive in water.

Incidentally, alloy stainless steel has a potential difference of zero or +0.01 to -0.5 port relative to water and oxygen in the aqueous dissolved oxygen solution. If the negative electrode 33 is magnesium and the water is set to 0 volt, an ionization potential difference of about 1.6 port and a maximum of about 1.8 port is generated.

As the negative electrode 33, in addition to the magnesium described above, a material similar to the negative electrode 13 described in the first embodiment is used.

The positive electrode 32 (blade EG) and the negative electrode 33 form a galvanic battery. They simultaneously come into contact with the skin or beard during use.

Therefore, according to the shaving device 3, the electrokinetic phenomenon is caused to act on the wet surface of the skin, which is the shaving surface (see Fig. 11), thereby causing the dissociation of water, and the electrolytic action and the electrolytic sterilization. Electrolytic deodorization decomposition, oxide film reductive peeling, effective spreading of ionic species, electrolytic ion penetration, and enhancement of magnesium / calcium activity by transfer of charged ions in the transition system of aqueous solution.

According to the shaving device 3, when the beard is cut with the blade EG, which is the positive electrode 32, the convergence due to oxidation-reduction of the cut surface of the beard and the swelling and softening due to the electrokinetic effect provide a feeling without roughness or tingling. (See Figure 13).

In addition to the effects of sterilization and eradication by the potential difference, the electrokinetic effect of ion dissociation prevents shaving loss and has a peeling effect in the beauty field.

As described above, according to the shaving apparatus 3, the daily operation of shaving, which has no apparent relation to cleaning, can simultaneously kill the beard and skin without the user's awareness. Bacteria and washing are performed.

FIG. 12 (A) shows the arrangement in the shaving apparatus 3 described above. The arrangement shown in FIG. 12 (B) is an example in which two positive electrodes 32 (blade EG) and two negative electrodes 33 are provided.

Fig. 12 (C) shows the anodic electrodynamic type in which a gripping electrode is provided on the shaver body 31 and the gripping electrode is connected to the positive electrode 32 (blade EG). 5 shows a cathodic electrodynamic type in which a gripping electrode and a negative electrode 33 are connected.

Between the positive and negative electrodes described above, dielectrophoresis (Di electrophoresis) occurs when wet with water. Here, the dielectrophoresis phenomenon in the cleaning device 1 will be described.

In the present embodiment, carbon is used as the positive electrode 12 and magnesium is used as the negative electrode 13, and these are gripped by hand, and the body is rubbed, stroked, and slid in an aqueous solution environment. This has a direct electric field effect on the living body part. Therefore, the threshold value for dissociation with water can be kept low without depending on a chemical solvent as in the past, and a bacteriostatic effect using water as a medium can be expected.

Magnesium is the only substrate that produces no biocompatible hydrogen ions (protons) in the reductive hydration dissociation of water without harm to the living body. The hydration reaction of magnesium with the hydrated calcium by the hydrogen ions of magnesium causes the hydration of its working system to be balanced through the balanced hydration of sodium and potassium. Oxidation correction by ions works (skin spreading effect).

FIG. 15 is a diagram illustrating the principle of dielectrophoresis, and FIG. 16 is a diagram illustrating the functional configuration of noble and vulgar.

As shown in FIG. 15, the cleaning apparatus 1 utilizes a dielectrophoretic phenomenon caused by an uneven electric field. Opposite-polarized charges are induced in the opposite parts of the positive and negative electrodes immersed in an aqueous environment. This produces an unequal electric field. The electric field strength differs depending on the position, and the ion particles are driven by using the difference in the force acting on the positive and negative polarization charges. The dielectrophoretic force in that case is proportional to the volume.

The main system of action involves oxidized ion, reduced ion exchange, and conversion. At the contact surface between the water-insoluble interface and the solution containing the redox system, only the electron particles theoretically migrate through the interface, and the ions of the working system are electrically charged by the solution dissociation action of the aqueous washing. The hydration of the ions is established. This results in decomposition, emulsification, and detachment.

As shown in Fig. 16, due to the difference in oxygen diffusion rate, a low-potential pole with a low self-potential (free-electron polarization-determining) potential acts as an anode, and a high-potential noble pole acts as a force source to generate a potential difference. I do. The proton generated by the polarization of magnesium in water is a negative pole anode reaction, and the ionic species is a proton ion. The noble pole becomes the cathode in potential, and the noble pole becomes the anode. In this potential effect, the cathode side is the pole of hydrogen ion generation, and as an underwater electric field effect and electrolysis phenomenon, the effect is further negative than the hydration dissociation potential of water of 7 volts.

In the embodiments described above, the structure, shape, dimensions, number, material, and the like of the substrate, the positive electrode, and the negative electrode can be variously changed. In addition, the structure of the electric stone, the toothbrush, or the shaver can be appropriately changed. In addition, the present invention can be applied in various ways other than the examples described above.

As described above, according to the present embodiment, the generated foam is easily decomposed by performing the electric field treatment, and the foam is reduced. In addition, it is possible to electrically sterilize and wash by electric potential difference due to the electrokinetic phenomenon.

In addition, by using magnesium for the negative electrode, a large electromotive force of about 1.5 ports can be obtained, thereby exhibiting a strong sterilizing effect.

In addition, the routine action of shaving provides sterilization and cleaning of the beard and skin. Industrial applicability

As described above, in the cleaning apparatus according to the present invention, the generated bubbles can be easily decomposed by the electric field treatment, and furthermore, can be electrically sterilized and cleaned by the potential difference due to the electrokinetic phenomenon, and thus the conventional stone cleaning apparatus can be used. It can be used as an alternative to the environment, and is useful for preventing environmental pollution.
