[embodiment]
The following example is to further explanation of the present utility model and replenishes, the utility model is not constituted any limitation.
The Combined type electric hotting mask of low electromagnetic of the present utility model is applicable to all electric heating products take Electric radiant Heating Film 10 as heating source.
Consult Fig. 1～Fig. 4, the Combined type electric hotting mask of low electromagnetic of the present utility model comprises Electric radiant Heating Film 10, screen 20 and wire 30, described screen 20 is used for the low frequency electromagnetic radiation that shielding Electric radiant Heating Film 10 is sent, and described wire 30 is used for connecting Electric radiant Heating Film 10 and external power source.
Embodiment 1
As shown in Figure 1, described wire 30 is connected with Electric radiant Heating Film 10 in known manner, and it is Electric radiant Heating Film 10 power supplies by connecting outside 220V power supply.End near power supply terminal on the described wire 30 is provided with magnet ring 31, and this magnet ring 31 is used for filtering the low frequency clutter of external power source, prevents that the low frequency clutter from causing interference to Electric radiant Heating Film 10, makes the electric heating film for heating performance more stable.Described magnet ring 31 can be the magnetic powder core magnet ring, also can be ferrite bead or coiling magnet ring, in the present embodiment, and preferred ferrite soft magnetic magnet ring.With before Electric radiant Heating Film 20 is fixedly connected with, select magnet ring 31 internal diameters to be slightly larger than the magnet ring of wire 30 external diameters at wire 30, this magnet ring 31 is enclosed within wire 30 outsides, and make it near the wherein end in wire 30 links, to reach better anti-electromagnetic interference effect.Then the heat-shrinkable T bush that internal diameter and magnet ring 31 external diameters is complementary is sleeved on the wire, with air-heater or thermal contraction machine heat hot Heat-Shrinkable Tubings, heat-shrinkable T bush is shunk and magnet ring is fixed on the wire, in known manner wire 30 is connected with Electric radiant Heating Film 10 again.
As shown in Figure 1, described Electric radiant Heating Film 10 can be any in the known Electric radiant Heating Film 10, and in the present embodiment, this Electric radiant Heating Film 10 is the translucent polyester film.The outer surface of described Electric radiant Heating Film 10 outside radiated electromagnetic wave one sides is upper surface, and its opposite side is lower surface.Described screen 20 is compound in the upper surface of Electric radiant Heating Film 10.Described screen 20 is permalloy film, and it can be the iron nickel alloy film of high magnetic permeability, also can be sendust film or amorphous cobalt base alloy film, in the present embodiment, and preferred iron nickel alloy film.Described screen 20 is compound in Electric radiant Heating Film 10 upper surfaces, and by high-temperature-resistant adhesive the edge of screen 20 and Electric radiant Heating Film 10 is bonded together.
When Combined type electric hotting mask 10 work of the present utility model, after described magnet ring 31 filtered the low frequency clutter in the external power source, external power source enters Electric radiant Heating Film 10 made Electric radiant Heating Film 10 generation infrared rays and certain wavelength be different from ultrared low-frequency electromagnetic wave.Described infrared ray sees through screen 20 and is radiated to space formation thermal radiation, directly heats the interior space.Because the magnetic permeability of described screen 20 is very high, so that screen 20 provides a path that magnetic resistance is very low for low-frequency electromagnetic wave, so that concentrating in the screen 20, described low-frequency electromagnetic wave major part can't penetrate screen 20, thereby when not affecting heating effect, greatly reduce the electromagnetic radiations emission that Electric radiant Heating Film 10 is radiated the space, greatly reduce electromagnetic radiation to the harm of human body.
Experimental data shows that the magnetic flux density of the electromagnetic radiation that common electrical hotting mask 10 produces is 10
-5T (i.e. 100 milligauss), the magnetic flux density of the electromagnetic radiation that the Combined type electric hotting mask 10 of low electromagnetic of the present utility model produces is 3 * 10
-7T(i.e. 3 milligauss) in the scope.
