Abstract
The utility model relates to an electromagnetic radiation protective helmet, particularly a protective helmet for preventing the electromagnetic radiation of mobile phones, interphones, transmitting stations and microwave ovens. The protective helmet is designed based on the principle that conductors have the function of electromagnetic shielding against electromagnetic waves, so that the electromagnetic waves radiated on human brains generate a skin effect on the conducting shield and are shielded or attenuated. The utility model prevents the electromagnetic field of electromagnetic waves from acting on human brains, which avoids some induced diseases. The utility model is mainly composed of a conducting shield made of electric conducting materials, and has the characteristics of favorable protective effect, low cost and convenient operation and portability. The utility model is suitable for people who are near to the emission source of electromagnetic waves.
Description
The utility model relates to the Protection of Electromagnetism Radiation cap of a kind of Protection of Electromagnetism Radiation cap, particularly mobile phone, intercom, transmitting station, micro-wave oven.
At present also do not find just in the maintenance of high-voltage fence, to use the metallic shield etting by the protector of electromagnetic wave to the human body head radiation, but this protection etting only limits to the security fields of high voltage, the maintenance of low-frequency electrical network.
Some communication equipments and household electrical appliance are in use, the electromagnetic wave that certain power and certain frequency scope are arranged to external radiation, and the electromagnetic wave emission source that has is very near apart from human body, such as mobile phone or intercom in use, their antenna distance human brain has only 1 to 10 centimetre far away, the electromagnetic wave of its antenna emission directly radiation in people's brain tissue.
The purpose of this utility model provides a kind of electromagnetic wave proof cap, and it can realize radiation to shield or weaken in the electromagnetic wave of human brain easily, prevents by this electromagnetic electromagnetic field effect in people's the some diseases that brain tissue brought out.
The utility model to electromagnetic principle of electromagnetic shield-ing, makes radiation produce Kelvin effect in that part of electromagnetic wave of human brain on the conductive material cover according to electric conductor, shields or weakens the effect of this electromagnetic field to human brain with this, thereby reach the purpose of electromagnetic wave proof.
Described electromagnetic wave proof cap, it comprises a usefulness and contains the conductive shield that conductive material is made.
Described conductive material comprises metal, metallic compound and graphite.
Described conductive shield can be the cover made by pure conductive material or by the mixed made cover of conductive material and non-conducting material.
Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing and preferred embodiment:
Fig. 1 is a preferred embodiment schematic diagram of the present utility model.
With reference to Fig. 1: the electromagnetic wave proof cap of present embodiment, it comprises an outer cover (1), and a liner (3) clips a conductor cover (2) that contains conductive material therebetween.Outer cover (1) and liner (3) can be made of cloth, the available multiply fine copper wire of conductive shield (2) (4) hold knitting wool (5) afterwards again the braiding form, bottom at cap can all connect together all fine copper wire heads, to guarantee the connection electric conductivity of conductive shield, conductive shield (2) can be driven among outer cover (1) and liner (3) down, and purpose is the cleaning that makes things convenient for this head protector.
The using method of electromagnetic wave proof cap of the present utility model:
Adopt the electromagnetic wave proof cap of the embodiment of Fig. 1, when the user is nearer apart from electromagnetic wave emission source, this head protector is worn on head upward gets final product.
The utlity model has that electromagnetic wave proof is effective, cost is low and wear convenient advantage.
Claims (3)
1, a kind of electromagnetic wave proof cap is characterized in that it comprises a usefulness and contains the conductive shield that conductive material is made.
2, electromagnetic wave proof cap as claimed in claim 1 is characterized in that conductive material can be metal or metallic compound or graphite.
3, electromagnetic wave proof cap as claimed in claim 1 is characterized in that conductive shield can be the cover made by pure conductive material or by the mixed made cover of conductive material and non-conducting material.
