Description

Device for removing the electromagnetic waves of cellular phone

The present invention relates to a mobile phone electromagnetic wave remover, and in particular, by molding lead and mumetal alloy to remove the static electricity and electric field harmful to the human body generated from the mobile phone, easy to use simply mounted on the antenna of the mobile phone It consists of a ring body to remove most of the electromagnetic waves generated from the mobile phone.

As it is well known, the development of civilization has made the mobile phone, a personal mobile communication, a necessity for modern people, and achieved the communication revolution.However, recently, it was reported to the academic community that harmful electromagnetic waves generated from mobile phones adversely affect the human brain. As a result, international standards for electromagnetic waves have been established and legally regulated.

The two factors that adversely affect the human body caused by mobile phones are static electricity and electromagnetic waves. Static electricity causes various skin diseases and breaks rhythms, causing diabetes and heart disease, while electromagnetic waves act as a biological clock in the human body. It is known to be very harmful to human body such as decrease of secretion amount of melatonin, which is a hormone in charge of it, change of distribution of ions such as sodium and potassium that pass through cell membranes, destruction of vision, induction of cancer and leukemia, increase of body heat, and promotion of skin aging. .

In 1984, the International Radiation Protection Association (IRPA) recommended tolerances for exposure to electromagnetic waves in the 100 kHz to 300 GHz band, based on the World Health Orgarningation (WHO) announcement. SAR refers to the rate of absorption of electromagnetic energy in living tissues. The unit uses Watt / kg and is a widely used term along with mW / cm 2 used to measure the degree of harmfulness of human body to microwaves. Table 1 and Table 2 below show the exposure limits of workers and the general public according to the frequency bands of radio waves and microwaves, and the unit of f is MHz.

TABLE 1

Frequency (MHz) Electric Field (V / m) Magnetic Field (mA / m) Power Density (mW / ㎠) 0.1 to 1 614 1600 / f -1 to 10 614 / f 1600 / f -10 to 400 61 160 1400 to 2000 3f ^0.5 8f ^0.5 f / 400 2000 to 3000 00 137 360 5

TABLE 2

Frequency (MHz) Electric Field (V / m) Magnetic Field (mA / m) Power Density (mW / ㎠) 0.1 to 1 87 230 / f ^0.5 -1 to 10 87 / f ^0.5 230 / f ^0.5 -10 to 400 27.5 73 0.2400 to 2000 1.375 f ^0.5 3.7 f ^0.5 f / 2000 2000 to 3000 0 0 61 160 1

In Table 1, the exposure limit below 10 MHz is based on the criteria that the average current induced in the human body by electromagnetic waves during 6 minutes during work should be 200 mA or less, and the exposure limit above 10 MHz is 0.4 W for 6 minutes. The reason is that it should be less than / kg. In addition, the exposure limits above 10 MHz in Table 2 are based on an average SAR of less than 0.08 W / kg for 6 minutes. SAR, the benchmark for exposure limits for workers and the general public, is 5: 1, and in most other regulations this ratio is between 5: 1 and 10: 1.

This difference is due to the fact that workers are aware of the exposure to electromagnetic waves and are reducing exposure, but the general public does not.

Since the mobile phone uses microwave at 800MHz, the exposure limit according to Table 2 is f / 2000 = 800/2000 = 0.4mW / ㎠, so the average power density for 6 minutes should be 0.4mW / ㎠ or less.

The present invention aims at minimizing electromagnetic waves generated from mobile phones based on the above criteria so that they can fall short of WHO regulations (less than 0.4mW / cm ² exposure limit). Mumetal and aluminum, which are electromagnetic wave shielding materials, are powdered and compounded in a predetermined ratio, and molded into a ring body that can be easily inserted into the antenna of a mobile phone. It is intended to be convenient.

Hereinafter, the present invention according to the accompanying drawings and preferred embodiments in detail as follows.

10-50% by weight of aluminum (Al) of the present invention and 90-50% by weight of mumetal are powdered, mixed, dissolved, and molded in a cylindrical shape to form a ring body 1, and the outer casing is made of copper (2). ) Was formed and then wrapped around the top circumference with a semicircular rubber ring (3) so that it can be used by inserting it into the antenna (5) of the mobile phone (4).

Aluminum used in the present invention has a purity of 99% or more, and has excellent permeability for absorbing and passing electric wave waves (electric field lines). Mumetal has 4% by weight of copper, 76% by weight of nickel, and iron 20 It is a special alloy composed of weight percent, and has a particularly excellent ability to absorb and pass waves of a magnetic field series.

The present invention is configured to absorb the electromagnetic field generated by the mobile phone by aluminum, the magnetic field by the mumetal absorbs the magnetic field and removes it into the air, thereby minimizing harmful electromagnetic waves generated during mobile phone calls to prevent brain damage. It will be done.

As described above, the present invention not only emits and extinguishes harmful electromagnetic waves generated by a mobile phone call below the WHO standard (exposure limit 0.4mW / cm ² or less), but also consists of a small cylindrical ring body, which is simply inserted into the antenna of the mobile phone. As well as being very convenient to use, there is a side effect that the ring body also serves as an accessory function of the mobile phone, it is useful to be able to produce a low price and widely distributed to the general public to greatly contribute to the protection of public health.
