1 to 4, the cleaning device 1 includes an anode member 11, insulating members 12a and 12b, and cathode members 13a and 13b. Insulation members 12a and 12b may be referred to as "insulation members 1 2" when referring to either or both. The same applies to the cathode members 13a and 13b.

The anode member 11 is made of a porous flexible body containing carbon (carbon). As the material, a sponge or sponge having open-celled and elastic properties is used. Carbon-containing substances include, for example, charcoal or graphite. Carbon is a noble metal or substrate in dissimilar metal contact corrosion, as described below. Since the anode member 11 contains carbon, it can be regarded as a kind of electric conductor.

Since the anode member 11 comes into direct contact with the skin of the living body when the body is washed, it is preferable that the anode member 11 is adapted to the living body, has a good feel, and generates an appropriate sliding friction in the cortex of the skin surface. . In addition, by using a porous open cell as the anode member 11, water penetrates due to its penetrability. This has the advantage of increasing the contact area with the skin surface.

In the present embodiment, the anode member 11 has a size such that it can be gripped by one hand and has a disk shape in a free state. A hole 51 is provided at the center thereof. The insulating member 12 is inserted into the hole 51 and attached. As a result, the central part of the anode member 11 is compressed, and is lower than the peripheral part. The insulating members 12a and 12b are made of an insulating material such as synthetic resin or ceramics. For example, a molded product such as a noryl resin or a polypropylene resin is used. Calcium cement-based materials can also be used. When a calcium-based material is used, calcium is ionized and dissolved in water, and forms an ion bond with magnesium precipitated from the cathode member 13 to be absorbed from the skin, thereby maintaining and maintaining skin homeostasis and activity. Is achieved.

The insulating members 1 2a and 1 2b are attached by fitting each other while penetrating the hole 51 of the anode member 11 and sandwiching the anode member 11 from both sides. 1 2a and 1 2b are disc-shaped flanges 6 1a and 6 1, respectively. b, and engaging portions 63 a and 63 b protruding from one surface of the flange portions 6 la and 61 b. Recesses 62a, 62b are provided in each flange 61a, 61b. The outer shape of the engaging portion 63 a is almost the same as the inner diameter of the hole 51, and the outer periphery of the engaging portion 63 b is tightly fitted into the inner periphery of the engaging portion 63 a so as to be in a tightly fitted state. Are engaged with each other.

The cathode member 13 is a dish-shaped metal plate that is spherically curved so as to protrude outward. It has an outer shape smaller than the outer shape of the flange portion 61 and fits into each of the recesses 6 2 a and 6 2 b. Thus, the anode member 11 and the cathode member 13 are insulated by the insulating member 12. Fixed together. The cathode member 13 and the insulating member 12 are mounted so as not to protrude outside the thickness of the anode member 11, that is, to fit inside the thickness of the anode member 11.

As a material for the cathode member 13, a metal that is more noble than carbon is used. In the present embodiment, magnesium is used. In a state of being wet with water, a dielectrophoresis (Dielec trophores is) phenomenon occurs between the anode member 11 and the cathode member 13.

Cathode member 13 is a portion that generates hydrogen ions and forms an electric cathode surface. Because of the spherical shape, the hydrogen ion particles diffuse radially toward the anode member 11 and cause a large amount of dielectrophoresis in a small area.

As described above, the anode member 11 and the cathode member 13 are arranged so as not to contact each other. They can be in simultaneous contact with the skin when used by humans. For example, by gripping with a hand, a palm or a finger comes into contact with the cathode member 13, and in this state, the anode member 11 is brought into contact with the face, torso, limbs, etc., and lightly rubbed as described above. As the anode member 11, a noble metal in dissimilar metal contact corrosion is used, and as the cathode member 13, a base metal in 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, metals such as carbon (graphite), platinum, nickel, chromium-molybdenum alloy C, titanium, nickel and chromium 'copper * silicon alloy B, nickel-iron and chromium alloy 8 25, alloy 20 and stainless steel It is. Graphite and platinum exhibit a potential on the order of +0.2 volts. Other metals show potentials near 0 volts.

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

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), and by maintaining the anticorrosion potential at a potential nobler than the critical potential, for example, -0.65 volts, Hydrogen absorption phenomenon can be prevented.

An example of use of the cleaning device 1 configured as described above will be described.

When the surface of the cleaning device 1 is dry (not wet with water), there is no potential difference between the anode member 11 and the cathode member 13 and no current flows. However, when the surface of the cleaning device 1 is wet with water or an aqueous solution, a galvanic battery is formed by the anode member 11 and the cathode member 13, and a large electromotive force of 1.5 volts or more can be obtained ( See Figure 4).

In other words, by using the cleaning device 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 frictional action causes the outside air to be mixed and diffused and dissolved on the surface-active surface. By the gas action that becomes the sum of dissolved oxygen in the liquid, the diffusion action of oxygen on the water-based surface forms an electrical connection using the water liquid as the conductive path in the distribution of two types of dissimilar metals. An internal current flows to 11 and the galvanic battery has a positive anode member 1 and a negative cathode member 13. By moving the cleaning device 1 or rubbing the skin, the solution is agitated, polarization is promoted, and the current effect is increased.

Furthermore, the use of the cleaning device 1 causes magnesium to precipitate out of the cathode member 13 at the grain boundaries, causing ionization and polarization of magnesium, and causing the water-soluble silica component to generate an electric field on the surface of the skin or the keratin epidermis, which is the cleaning surface. It reacts actively due to the coagulation effect, and activates the skin by silica crosslinking, ion reduction, and ion redeployment.

In addition, since bacteria existing in a living body are killed by receiving a voltage of about 5 volts, it is necessary to move the cleaning device 1 with the anode member 11 and the cathode member 13 in contact with human skin. Or by rubbing, the surface of the skin is sterilized or sterilized. Therefore, there is an odor-preventing effect of preventing odors caused by the propagation of bacteria. Also, in that case, it is not necessary to use a large amount of soap as in the prior art, so that a large amount of foam is not generated.

In addition, when the cleaning device 1 is used, 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. However, a large amount of foam does not remain when drained into sewage.

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 the cleaning device 1 is used, the balance between magnesium and calcium is adjusted together with the cleaning of the skin, and care is performed.

Thus, the cleaning device 1 can be used as an electric stone instead of the conventional stone when taking a bath. In addition, it can be used as an electric puff instead of a conventional puff in makeup. When used as an electric puff, the cleaning device 1 is held by hand so as to contact the cathode member 13, and the surface of the anode member 11 is brought into contact with a face or the like, and rubbed lightly. As a result, skin can be expected to have a cleaning effect, a sterilizing effect, an activating effect, an adjusting effect, a cosmetic effect, and a peeling effect.

Next, the dielectrophoretic phenomenon in the cleaning device 1 will be described. As described above, in the present embodiment, carbon is used for the anode member 11 and magnesium is used for the cathode member 13. Hold these with your hands and rub, stroke, and slide on the body in an aqueous environment. As a result, an electric field effect is directly exerted on the body part. Therefore, the threshold value of the dissociation action with water can be kept low without depending on the 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 ion causes the hydration of the working system through the balanced hydration reaction of sodium and potassium, which consequently reduces the power of the living body. Oxidation correction by hydrogen ion works (skin spreading effect).

As shown in FIG. 5, the cleaning apparatus 1 utilizes a dielectrophoretic phenomenon caused by an uneven electric field. In the anode member 11 and the cathode member 13 immersed in the aqueous solution environment, opposite polarity polarization charges are induced in opposing portions. This produces an unequal electric field. The electric field strength differs depending on the position, and the ion particles are driven using the difference in the forces 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. 6, due to the difference in oxygen diffusion rate, a low potential negative electrode with a low self potential (free electron polarization control) acts as an anode, and a high potential noble pole acts as a force source to generate a potential difference. I do. The protons generated by the polarization of magnesium in water are anodic reactions at the base pole, and the ion species are proton ions. The lower pole becomes the potential negative pole, and the noble pole becomes the anode. In this potential effect, the cathode side is a pole for generating hydrogen ions, and as an underwater electric field effect and electrolysis phenomenon, the effect is further negative than the hydration dissociation potential of water of 0.7 volt. In the embodiment described above, the two cathode members 13a and 13b are identical to each other in shape, dimension, and material. On the other hand, it is possible to use only one of the members, for example, the cathode member 13a only, as described above, and to make the other cathode member 13b of a different material and use it as an auxiliary member.

As such a material, for example, oxygen-free copper or a silver alloy can be used. For example, when a cathode member 13b made of oxygen-free copper is used, effects such as bacteriostatic, antibacterial, and bactericidal effects are produced. It also has the effect of breathing or breathing.

Also, it is possible to use magnesium for one cathode member 13a and magnesium (Li-Mg) containing lithium for the other cathode member 13. In this case, a panel made of a conductor is attached between the cathode member 13a and the cathode member 13b to electrically short-circuit them, and water enters the insulating member 12. It is necessary to seal it so that it does not occur.

In the embodiment described above, the shape of the anode member 11 is circular, but may be various shapes such as a square, a pentagon, a hexagon, an octagon, an ellipse, and a gourd. In addition to such geometric shapes, fish, animals, plants, cartoon and television characters, vehicles, and various other design shapes may be used. The shape of the cathode member 13 is circular, but may be other various shapes. The number of the cathode members 13 is not limited to one or two, but may be three or more. Various methods can be employed for attaching the anode member 11 and the cathode member 13 to each other.

In addition, the structure, shape, size, number, material, etc. of the anode member 11, the insulation member 12, the cathode member 13, or the whole or each part of the cleaning device 1 are variously changed in accordance with the gist of the present invention. be able to.

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.

When the cleaning device is used as an electric puff, various cosmetic effects on the skin can be expected. 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.
