Abstract

The utility model relates to an electromagnetic mask electric heating blanket, composed of heating wires, an upper insulation layer, a lower insulation layer, an upper conducting wire dead plate, a lower conducting wire dead plate, a power lead, a power source attachment plug, and a screen. The utility model is characterized in that heating wires are nipped between two insulation layers; the upper conducting wire dead plate and the lower conducting wire dead plate are fixed on the upper insulation layer and the lower insulation layer which are arranged in the joint of heating wires and the power lead; the screen attaches to the upper insulation layer and contacts with the upper conducting wire dead plate; the upper conducting wire dead plate is connected with the earth wire of the power source attachment plug; the upper conducting wire dead plate is a conductor plate. The utility model has the advantages that the electromagnetic mask electric heating blanket can protect people from being radiated by electromagnetic field, can be used safely, etc.

Description

Electromagnetic mask electric heating blanket

The utility model relates to a kind of family expenses insulated bed Bed linens, and being described more specifically is a kind of electric blanket.

At present, the electric blanket of being sold all is sewn to heating wire among the two-layer insulation acrylic blanket on the market, and turn-on current produces heat.For the warming use of people.Though can play thermal effect, heating wire has also produced electromagnetic field except producing the heat, and electromagnetic field is penetrated and can be caused very big harm to human body the long-term width of cloth of human body.It is exactly a good example that pregnant woman as well known uses electric blanket to cause baby's deformity.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of heating effect that both had is provided, and is not subjected to the electromagnetic shielding electric blanket of electromagnetic radiation again.

The purpose of this utility model can reach by following measure: this electromagnetic shielding electric blanket is made up of heating wire, time insulating barrier, power line, attaching plug, last insulating barrier, lower wire fixed head, upper conductor fixed head.Heating wire is clipped between insulating barrier and the following insulating barrier, and sews up with sewing thread.Upper conductor fixed head and lower wire fixed head are clipped on the last insulating barrier and following insulating barrier at electricity silk and power cord connector place, and fix by nut and screw.Power line is connected with power connection.The screen layer of plating one deck electrically conductive film conduct on the upper surface of insulating barrier on described.The solid plate of described upper conductor is a conductor plate, and contacts with screen layer.Be connected with the ground wire of attaching plug again.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation profile of the present utility model.

The utility model is by heating wire (1) as shown in Figure 1, last insulating barrier (2), and following insulating barrier (3), upper conductor fixed head (4), lower wire fixed head (5), power line (6), attaching plug (7) becomes with screen layer (8).Following insulating barrier (2) is the acrylic blanket, and the composite of last insulating barrier (2) and screen layer (8) is a metal space silk floss, and lower wire fixed head (5) is the common plastics plate, and upper conductor fixed head (4) is a metallic plate.Heating wire (1) is sandwiched between acrylic blanket and the metal space silk floss, and sews up with sewing thread.Upper conductor fixed head (4) and lower wire fixed head (5) are clipped on the acrylic blanket and metal quilted car cotton of joint of heating wire (1) and power line (6), and with screw, fixed by nut, upper conductor fixed head (4) contacts with the metallic diaphragm of metal space silk floss.The ground wire of attaching plug (7) is connected by screw with upper conductor fixed head (4).The operation principle of this electromagnetic shielding electric blanket is: in electric current flows through electric blanket and during heating wire, except that producing heat, certainly lead to electromagnetic field, just can mask electromagnetic field owing on electric blanket, spread the electrically conductive film (comprising metal or non-metal conductor) of conduction, the induced-current that is produced on the electrically conductive film is by ground wire grounded, so just harmless.

The utility model has following advantage with respect to prior art: non-electromagnetic field is penetrated the human body width of cloth, thereby this product is harmless, adds and is connected to ground wire, thereby people are used safety.

Claims (1)

1, the electromagnetic shielding electric blanket, by heating wire (1), last insulating barrier (2), following insulating barrier (3), upper conductor fixed head (4), with lower wire fixed head (5), power line (6) and attaching plug (7) are formed, heating wire (1) is sandwiched between insulating barrier (2) and the following insulating barrier (3), and sew up with sewing thread, upper conductor fixed head (4) and lower wire fixed head (5) are clipped on the last insulating barrier (2) and following insulating barrier (3) of joint of heating wire (1) and power line (6), and be connected with attaching plug (7) by nut and the screw power line (6) that is fixed together, it is characterized in that: on described on the surface of insulating barrier (3) the plated conductor film as screen layer (8), described upper conductor fixed head (4) is a conductor plate, and contact with screen layer (8), the ground wire with attaching plug (7) is connected again.
