Description

Electromagnetic Wave Isolation Device

technical field

The invention relates to an isolation device, in particular to an electromagnetic wave isolation structure capable of effectively blocking electromagnetic waves. the

Background technique

Due to the use of electronic and electrical products in daily life, the surrounding environment is full of electromagnetic waves. Although there is no definite research report to confirm the harm of electromagnetic waves to the human body, according to the University of North Carolina-Savitz et al. .Study: Babies exposed to 60 Hz magnetic fields for a long time and used electric blankets during pregnancy have a 1.3 times higher incidence of cancer and a 2.5 times higher incidence of blood cancer and brain tumors than those who did not. In 1987, the University of North Carolina-Savitz et al. pointed out that the relative risk of blood cancer increased in the study of radio broadcasting and radar operators.

In 2000, according to the United Daily News on April 5th: British Consumer Association Which magazine warned that when using a hands-free mobile phone, the brain receives three times more electromagnetic waves than when using a mobile phone. It is true that in some cases, too strong electromagnetic waves will cause people to feel uncomfortable and cause various lesions. This phenomenon is more obvious especially when using a mobile phone, and some scholars believe that the harm of electromagnetic waves to the human body does exist, and the degree of harm will increase with the accumulation of exposure time.

However, in daily life, in addition to the obvious generation of electromagnetic waves by mobile phones, electronic products such as computers, televisions, and even electric fans will also generate electromagnetic waves. The form of the anti-electromagnetic wave patch designed for the use of the phone is presented, and the anti-electromagnetic wave patch is mainly formed by its own conductive rubber material or conductive metal sheet to block electromagnetic waves. However, due to the high cost of its conductive rubber, it makes It is not suitable for the production of larger patches, and because the texture of conductive rubber is relatively hard, when it is used in mobile phones, the volume will be reduced because the rubber material or metal sheet is not ventilated. In addition, it will also make the user feel uncomfortable, so that the applicability thereof is reduced.

Referring to Fig. 1, there are currently electromagnetic wave shielding patch products on the market, which are commonly used on the door of a microwave oven or on a mobile phone. The main body 1 has a stainless steel wire mesh bottom layer 12 and a fiber mesh bottom layer 11, both Then use the adhesive to overlap each other and then fix it, and fix it to the surface of the stainless steel wire mesh bottom layer 12 facing the user. However, since the shielding patch is fixed with two mesh layers, the magnetic wave shielding effect is not good, and if the fixing method is improper, the second and upper mesh layers are easy to fall off. In addition, the pasting process will increase the production cost, so Unable to achieve the desired effect.
