Abstract
Description
Technology Field
[0001] The present invention relates to a harmful electromagnetic wave neutralizing gender, and more specifically, to a harmful electromagnetic wave neutralizing gender for supplying power to an electrical device by neutralizing harmful electromagnetic waves contained in the current supplied along a conductor. Background Technology
[0002] Generally, electromagnetic waves refer to the phenomenon in which an electromagnetic field whose intensity changes periodically propagates through space. They are generated when electric charges vibrate rapidly or currents change oscillatorily, and it is known that electric and magnetic fields vibrate together perpendicular to the direction of wave propagation.
[0003] It is generally known that the strength of a magnetic field affecting the human body is 2 to 3 mG or higher; compared to the Earth's magnetic field strength of 600 mG, this is a considerably weak amount. However, experts say that even a magnetic field of this magnitude has a significant impact on the human body. This is because stable magnetic fields like the Earth's maintain constant polarity and direction, so the human body is adapted to them and poses no major harm; whereas the magnetic fields of harmful electromagnetic waves, which change from moment to moment, affect the human body even if their quantity is weak.
[0004] Harmful electromagnetic waves emitted from various electrical facilities and devices, including electrical outlets that the general public frequently encounters in homes and offices, are colorless, odorless, and invisible to the naked eye; however, it is known that they cause damage to the body through thermal, non-thermal, and irritating effects as they accumulate over time.
[0005] In addition, nerve, cell, and hormone activities in our body are regulated by minute electrical signals, and it is reported that when the human body is exposed to harmful electromagnetic waves, the flow of intercellular ions such as sodium and potassium is disrupted, leading to physical disorders.
[0006] Electrical outlets are used to supply power to various electrical devices, and it has been reported that the current flowing through these outlets contains a large amount of harmful electromagnetic waves. Furthermore, it has been reported that when this current containing harmful electromagnetic waves is supplied to various electrical devices, including computers and electric heaters, there is a risk that large amounts of harmful electromagnetic waves will be emitted to the human body when each device is used.
[0007] Korean Utility Model Application No. 20-2002-0036520 discloses an 'electromagnetic wave blocking outlet device'.
[0008] Looking at the prior art, it is a technology that prevents harm to the human body and device malfunction caused by electromagnetic waves by grounding the electronic device to the power grounding terminal of an existing building to eliminate electromagnetic waves generated by the device and noise from the input power.
[0009] Although many devices have been developed in the past to block such harmful electromagnetic waves, they have had several problems, including increased product costs due to their complex structures, difficulties in assembly and production, inability to apply them widely to various electronic devices thus failing to provide a substantial electromagnetic wave blocking effect, and significant inconvenience for users such as difficulty in operation and the inability to check the operating status, which prevents convenient use in daily life.

[0024] The harmful electromagnetic wave neutralizing gender according to the present invention is,
[0025] In a harmful electromagnetic wave neutralizing gender that is coupled to a USB terminal (not shown) of an electric device, wherein a USB plug (110) is formed at one end and a current-carrying wire (100) is provided,
[0026] A space is formed inside for inserting the above-mentioned wire (100), and inlets are formed on both sides of the outside, and a main body (2) is coupled to the outside of the above-mentioned wire (100) to protect the wire;
[0027] A protective cover part (4) inserted into the interior of the main body (2) and coupled to one side of the outside of the wire (100) to block electromagnetic waves; and
[0028] It includes a shielding part (6) that is inserted into the interior of the main body (2), is coupled to the other side of the external wire (100), has a sealed space, and has a coating layer (62) formed on its inner surface to absorb electromagnetic waves.
[0029] The main body (2) has a protective cover (4) and a shielding part (6) inserted inside, and the protective cover (4) and the shielding part (6) are coupled to the outside of the wire (100) inserted into the main body (2).
[0030] It includes a position setting part (5) that sets the position by moving the above protective cover part (4) inside the main body (2).
[0031] The above position setting unit (5) is
[0032] A rail groove (52) having a predetermined length and embedded in the inner surface of the main body (2), and
[0033] It is configured to include a rail projection (54) formed on the outer surface of the protective cover portion (4) and inserted into the rail groove (52).
[0034] Accordingly, the rail protrusion (54) of the protective cover part (4) is coupled to the rail groove (52), and the protective cover part (4) can be moved to one side and set to a suitable position along the rail groove (52).
[0035] It also includes a fixing means for temporarily fixing the rail projection (54) at a predetermined position of the rail groove (52).
[0036] The fixing means is
[0037] A magnetic metal plate (522) formed longitudinally at the bottom of the rail groove (52), and
[0038] It is configured to include a magnetic body (542) formed on the rail protrusion (54) and magnetically attached to the magnetic metal plate (522).
[0039] Accordingly, the protective cover part (4) can be moved to one side so that the rail protrusion (54) can move along the rail groove (52), and additionally, the position can be temporarily fixed by the magnetic fixing force of the magnetic body (542) and the magnetic metal plate (522) at a certain position.
[0040] By fixing the position in this way, it is possible to control the movement of the protective cover (4) to a suitable position.
[0041] Meanwhile, it may include an electromagnetic wave absorbing material (45) filled inside the protective cover part (4).
[0042] Electromagnetic wave absorption is the process of shielding by dissipating electromagnetic waves into thermal energy or the like within a material, rather than reflecting them.
[0043] Electromagnetic wave absorption utilizes dielectric loss and magnetic loss.
[0044] Dielectric loss is the dissipation of electric field energy as heat within a dielectric material.
[0045] Magnetic loss is the dissipation of magnetic field energy as heat within magnetic materials (ferrite, magnetic metal particles, etc.).
[0046] To increase the absorption rate, the surface impedance of the shielding material is adjusted to be similar to the impedance of air (approx. 377Ω) to minimize reflection of electromagnetic waves (non-reflective condition), and the waves are transmitted into the material to dissipate energy through an absorption mechanism.
[0047] The above electromagnetic wave absorbing material (45) is made of a metal alloy, soft ferrite, and composite material.
[0048] The above metal alloy is one or more selected from the group consisting of Permalloy, mumetal, and silicon steel sheets.
[0049] Permalloy is a magnetic alloy composed of 80% nickel (Ni) and 20% iron (Fe), and has high magnetic transmittance and low magnetic distortion characteristics.
[0050] Mu-metal is an alloy composed of nickel, iron, copper, chromium, or molybdenum, and blocks electromagnetic waves.
[0051] Soft ferrite is a soft magnetic ceramic material made by mixing iron oxide (Fe2O3) and metal oxides. Due to its high permeability, it is effective for magnetic field shielding by absorbing or redirecting magnetic fields, and is utilized in applications such as EMI filter cores and absorption sheets.
[0052] The above composite material is an amorphous or nanocrystalline alloy, possesses excellent permeability and low loss characteristics, and is used in high-performance power and communication fields.
[0053] Here, the aforementioned permeability is a value indicating the ability to accept a magnetic field and how strongly that magnetic field can be generated.
[0054] Meanwhile, the coating layer (62) of the shielding part (6) is
[0055] It is one or more selected from the group consisting of ferrite-based absorbers, carbon-based absorbers, resonant absorbers, and pyramidal absorbers.
[0056] Ferrite-based absorbers are a mixture of ferrite powder and a polymer binder and have excellent magnetic loss characteristics.
[0057] Carbon-based absorbents are a mixture of carbon nanotubes (CNT), graphene, carbon black, and polymers.
[0058] A resonant absorber has a multilayer structure of a dielectric layer, a loss layer, and a reflective metal plate, and maximizes absorption by inducing resonance at a specific frequency.
[0059] The pyramidal absorber is made by processing carbon / ferrite-containing foam into a pyramid shape, and it efficiently absorbs broadband electromagnetic waves through changes in impedance.
[0060] Meanwhile, it includes a filling material (24) that is filled inside the main body (2) to shield electromagnetic waves.
[0061] The above filler (24) is composed of one or more selected from the group consisting of ceramic powder, metal-coated ceramic powder in which copper or nickel is coated on the surface of ceramic granules, Ti₃CN MXene, and composite materials in which ceramic and metal nanomaterials are mixed.
[0062] Ceramic powder has high electrical insulation properties, so rather than directly reflecting electromagnetic waves, it absorbs and scatters some of them.
[0063] Metal-coated ceramics are produced by coating the ceramic surface with metals such as copper or nickel, which creates conductivity and enables reflection shielding.
[0064] Ti₃CN MXene is a ceramic-based nanomaterial that absorbs electromagnetic waves and converts them into thermal energy, providing excellent high-frequency shielding performance.
[0065] Composite materials are a mixture of ceramics and metal nanomaterials, enabling the simultaneous securing of lightness, heat resistance, and shielding performance.
[0066] Therefore, when ceramic is used as the above-mentioned filler, it exhibits heat resistance, corrosion resistance, lightweight properties, and absorbent shielding performance.
[0067] Meanwhile, there is a concern that heat energy may be generated in the main body (2) during the process of absorbing electromagnetic energy.
[0068] Accordingly, the main body (2) may include a heat dissipation means (7) formed on the outer surface.
[0069] The heat dissipation means (7) can be detachably provided on the main body (2).
[0070] As an example, the heat dissipation means (7) may be detachably provided by being coupled to a slot (20) formed on the outer surface of the main body (2).
[0071] The heat dissipation means (7) is
[0072] It consists of a housing (72) with openings formed on both sides, a fan (73) formed inside the housing (72) and configured to pass through the openings, and a motor (74) that rotates the fan (73).
[0073] Additionally, on the outer surface of the housing (72), a projection (721) is formed on the upper side that is fitted into the slot (20), and on the lower side of the outer surface, a coil (75) filled with cooling liquid and a circulation pump (76) connected to the coil (75) to circulate the cooling liquid are included.
[0074] The circulation pump (76) is driven by a battery and includes a sensor (77) mounted on the main body (2) to measure the temperature of the main body (2), and a controller (78) connected to the sensor (77) to turn on the circulation pump (76) when the temperature rises above a certain level.
[0075] When the circulation pump (76) is turned on, the cooling liquid circulates along the coil (75), and the cooling heat of the coil (75) is transferred to the main body (2) in contact with the housing (72), thereby cooling the thermal energy generated during electromagnetic shielding in the main body (2).
[0076] Although described in relation to preferred embodiments, those skilled in the art will readily recognize that various modifications and variations are possible without departing from the essence and scope of the invention, and it is obvious that all such changes and modifications fall within the scope of the appended claims.
