1. Field of the Invention
The present invention relates to head coverings and more particularly, to an electromagnetic wave blocking head covering, which comprises a head covering body having an electromagnetic wave blocking layer formed on an outer or inner side thereof or embedded therein by one of the techniques of weaving, stitching, doping and coating for protecting wholly or partially the head of a person against external magnetic waves.
2. Description of the Related Art
Electronic products, such as cell phones, computers, copy machines, electronic home appliances and etc. are intensively used in our daily living. These electronic products emit electromagnetic waves during operation. According to investigation, long period exposure to electromagnetic waves is harmful to human body health. Electromagnetic waves may cause damage to cranial nerves, brain cells, heart and blood vessels, reproductive systems, genes, immune systems, endocrine systems, blood circulation systems, leading to tumor, brain lesions or other diseases.
Wearing a metal helmet or shielding device can protect the head of a person against external magnetic waves. However, conventional metal head protection devices are commonly heavy, rigid, uncomfortable, and not practical for use in people's daily living.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide an electromagnetic wave blocking head covering, which protects the user's head against external electromagnetic waves
To achieve the object of the present invention, an electromagnetic wave blocking head covering comprises a head covering body having a silver, copper or ferrite-contained electromagnetic wave blocking layer formed on the outer or inner side thereof or embedded therein by one of the techniques of weaving, stitching, doping and coating and capable of protecting the head of a person against external electromagnetic waves.
Further, the electromagnetic wave blocking layer can be made by weaving silver threads with cotton threads and synthetic threads, silver threads with natural threads and synthetic threads, or silver threads with natural threads and synthetic threads.
Referring to
Further, the electromagnetic wave blocking layer 10 can be a piece of silver, copper or ferrite-contained cloth, or a piece of silver, copper or ferrite-contained foam material.
Further, the electromagnetic wave blocking layer 10 can be formed on the inner or outer side or middle layer of the head covering body 11 or embedded therein by one of the techniques of weaving, stitching, doping and coating. For example, the electromagnetic wave blocking layer 10 can be made by weaving silver, copper or ferrite threads with cotton threads and synthetic threads, silver threads with natural threads and synthetic threads, or silver threads with natural threads and synthetic threads. Alternatively, the electromagnetic wave blocking layer 10 can be a silk fabric, cotton fabric, knit fabric or wool fabric, or any of a variety of other natural or synthetic fabric doped or coated with silver, copper or ferrite.
Preferably, the electromagnetic wave blocking layer 10 contains 90%˜50% cotton and 10%˜50% silver, copper or ferrite, or 90%˜50% natural fiber and 10%˜50% silver, copper or ferrite fiber, or 90%˜50% synthetic fiber and 10%˜50% silver, copper or ferrite fiber.
In conclusion, the invention provides an electromagnetic wave blocking head covering, which has advantages as follows:
1. The head covering body 11 of the electromagnetic wave blocking head covering 1 is provided with an electromagnetic wave blocking layer 10 that can be formed on the inner or outer side of the head covering body 11 or embedded therein. When a person wears the electromagnetic wave blocking head covering 1, the electromagnetic wave blocking layer 10 protects the user's head (cranial nerves and brain cells) against external electromagnetic waves.
2. The electromagnetic wave blocking layer 10 can be a woven fabric containing silver fibers, or a natural or synthetic fabric doped or coated with silver, providing wearing comfort.
While only few embodiments of the present invention have been shown and described, it will be understood that various modifications and changes could be made thereunto without departing from the spirit and scope of the invention disclosed.
