Abstract
The utility model relates to an electric heating apparatus without electric field radiation, which comprises a body and a heating element installed inside the body, wherein an electromagnetic shielding layer for preventing electric field radiation is arranged outside an insulating layer of the heating element. When a heating element is powered on for heating, an electric field can produced around, a person's body almost clings to the heating element of an electric heating apparatus when sleeping on an electric blanket, here, the person lies in higher electric field environment, thereby being unhealthy, however, the electric heating apparatus without electric field radiation is provided with the electromagnetic shielding layer outside the heating element, by which the out releasing of the electric field is effectively prevented, and users' heath is protected through avoiding the irradiation of a stronger electric field.
Description
Technical field
The utility model relates to a kind of electroheat equipment with anti-electric field radiation function, belongs to small stores class technical field.
Background technology
Electric blanket is a kind of domestic electric heating product of quite popularizing, and it quite is subjected to the old man and fears cold crowd's welcome some winters.When electric blanket is switched on, inevitably can produce electric field around the heater.Because distance is very near, so electric field is stronger.For the consideration to health, people adopt before sleep energising a period of time earlier usually when using electric blanket, powered-down more in bed, and the heating function of electric blanket just can not be fully utilized like this.Therefore, in order to solve heating and to avoid being subjected to contradiction than highfield irradiation, we provide a kind of electric field of effectively avoiding in the electroheat equipment to the irradiation hazard of human body and no electric field radiation electroheat equipment safe in utilization.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of electroheat equipment that can effectively eliminate electric field in the electroheat equipment to the irradiation hazard of human body and manufacturing process no electric field radiation simple, safe in utilization is provided.
The technical solution of the utility model is as follows:
A kind of no electric field radiation electroheat equipment, comprise device body, be arranged on the heater in the device body, wherein said heater is a heating wire, injection moulding one layer insulating on heating wire, at insulating barrier outsourcing last layer metal screen layer, the one side of metal screen layer scribbles conducting resinl, can be bonded at the outside of heater, plays the effect that prevents that electric field from leaking.
Main feature of the present utility model is to prevent that the electric field that electroheat equipment produces from leaking, effectively eliminate of the infringement of heater electric field to health, can use for a long time, and can give full play to the heating function of electroheat equipment, and has the advantage that manufacturing process is simple, easy to operate, do not increase cost.Heater described in the utility model can be applicable to multiple heating system, comprises electric blanket, under blanket, electric pad etc.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Embodiment 1
As shown in Figure 1, a kind of no electric field radiation electric blanket of the utility model comprises blanket body 1, is arranged on the heater in the blanket body, and wherein said heater is a heating wire 2, in heating wire 2 outsides are layer insulatings 3, prevent the screen 4 of electric field radiation then at insulating barrier 3 outsourcing last layers.Wherein, screen 4 is metal formings that one side scribbles conducting resinl, wraps in the heating wire outside with the method for twining.When switching on to heater, screen 4 has shielded the electric field that produces around the heating wire 2, makes it and can not leak.Thereby effectively eliminated electric field radiation, and made the human body of contact electric blanket not be subjected to irradiation than highfield.
A kind of screen 4 that does not have the electric field radiation electric blanket of the utility model can be the metal forming that one side scribbles conducting resinl, it also can be woven wire, or Electromagnetically shielding fabrics, comprise stainless steel metal wire and polyester cotton, metal coating fabric, acrylic fibers conductive fabric and their loomage etc. of deriving.
Embodiment 2
As shown in Figure 2, the utility model is a kind of no electric field radiation electric pad, be mainly used in the seat heating, comprise pad 5, be arranged on the heater in the pad, wherein said heater is a heating wire 6, in the outside of heating wire 6 are layer insulatings 7, prevent the screen 8 of electric field radiation at coated outside one deck of insulating barrier 7.Wherein, screen 8 is metal formings that one side scribbles conducting resinl, wraps in the heating wire outside with the method for twining.When switching on to heater, screen 8 has shielded the electric field that produces around the heating wire 6.Make it and to leak, thereby effectively eliminated electric field radiation, and make the unlikely irradiation that is subjected to than highfield of human body of contact electric pad.
A kind of screen 8 that does not have the electric field radiation electric pad of the utility model can be the metal forming that one side scribbles conducting resinl, it also can be woven wire, or Electromagnetically shielding fabrics, comprise stainless steel metal wire and polyester cotton, metal coating fabric, acrylic fibers conductive fabric and their loomage etc. of deriving.
The structure connections of material that the utility model is used and other parts etc. are identical with prior art, do not repeat.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection range of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
