Abstract
The utility model relates to an electromagnetic wave protection cover for mobile phones, which is composed of a transparent basal body and a layer. The utility model is characterized in that the net layer is arranged in the transparent basal body. When the utility model is used, the utility model is bound on the inner side and two side faces of a mobile phone to form a hood, and the utility model absorbs directly the electromagnetic waves generated by the mobile phone, reduces magnetic fields generated by the electromagnetic waves more than 50%, eliminates effectively the damage to the human body and precision instruments and protects the benefit of consumers.
Description
The utility model relates to protective cover, refers to a kind of mobile phone electromagnetic wave proof cover especially.
In the high and new technology field, mobile phone is used by increasing people.The electromagnetic wave that mobile phone emits is 30V/M after tested.People often paste telephone set and pay in one's ear when using telephone set, after long-term the use, produce dizzy, feel sick, the situation of failure of memory.Electromagnetic wave has been made big quantity research to the harm of human body abroad.The utility model is at the problems referred to above for this reason, provides to be reduced by at least 50% electromagnetic wave, eliminates a kind of mobile phone electromagnetic wave proof cover to human body harm.
The purpose of this utility model is achieved in that a kind of mobile phone electromagnetic wave proof cover is made up of transparent base, stratum reticulare, and it is characterized in that: stratum reticulare places in the transparent base.
Utilize the utility model directly to be bonded on the front and side of mobile phone, can directly absorb the electromagnetic wave of phone, protect the keyboard and the display of mobile phone simultaneously, and do not influence the another side of communication emission.After tested: electromagnetic wave magnetic field descends more than 50%, has reduced mobile phone effectively in use to the infringement of human body, has protected numerous users' health.
The utility model further specifies by the following drawings and embodiment:
Fig. 1: be the utility model structure chart (one)
Fig. 2: be the utility model structure chart (two)
Fig. 3: be the utility model user mode figure
Referring to Fig. 1: mobile phone electromagnetic wave proof cover is by transparent base 1, and stratum reticulare 2 is formed, and wherein stratum reticulare 2 places in the two-layer transparent base 1, and transparent base 1 is selected for use, and material wear-resisting, that light transmission good, intensity is high, soft is made, as the polyester film etc.Select the plastic film matrix in this example for use, stratum reticulare 2 directly places in the two layers of plastic film, can adopt different process to fix, as ion sputtering, vacuum coating, spraying, stickup etc.The nesa coating that stratum reticulare 2 materials can be metal-plated rete, wire netting or make with other metal oxides, or conducting polymer composite and electrically-conducting paint.Mainly be with having high conductivity, the material of high permeability is made, and has certain transmittancy, so that be clear that keyboard and display on the mobile phone.
Referring to Fig. 2: stratum reticulare 2 places transparent base 1 one sides, is pressed into one.
Referring to Fig. 3: during use; front and side that the composite membrane that above-mentioned material is made is bonded in mobile phone form a protective cover; play the effect of protection telephone set and reduce electromagnetic effect, the long-term also replaceable cover body in back that uses, cleannes, the transparency of maintenance cover body.Simple in structure because of it, with low cost, can be widely used on the mobile phone, on the video screen, on the door for microwave oven.This protective cover also can directly be bonded on the outer casing inner wall face of mobile phone, plays the anti-electromagnetic radiation effect.
