Obviously, not all but only some embodiments of the present invention are described here. On the basis of the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope protected by the present invention.

(6) With reference to FIGS. 1 to 3, an embodiment of the present invention includes: an infrared sauna room with a low electric field and low electromagnetic wave radiation comprising a room body 1, heating plates 2 with a low electric field and low electromagnetic wave radiation and shielding lines 3, wherein the room body 1 comprises a top cover 11, a side sheet 12, a rear sheet 13, a front sheet 14, a base 15 and a baffle plate 16, the side sheet 12, the rear sheet 13, the base 15 and the baffle plate 16 are provided with the heating plates 2 with a low electric field and low electromagnetic wave radiation which are connected to corresponding shielding lines 3.

(7) The heating plate 2 with a low electric field and low electromagnetic wave radiation comprises a first insulating layer 21, a second insulating layer 22, a third insulating layer 23, a fourth insulating layer 24, a fifth insulating layer 25, a first electric field shielding layer 26, a second electric field shielding layer 27, a first heating body 28 and a second heating body 29. The first heating body 28 and the second heating body 29 are respectively conductive heating graphene or conductive heating carbon black. Since sinusoidal alternating currents of the two heating bodies have phases opposition to each other, electromagnetic waves generated by the two heating bodies have phases opposition to each other; and when the two waves are overlapped, electromagnetic wave radiation is effectively removed via offset.

(8) An upper surface and a lower surface of the first heating body 28 are provided with the second insulating layer 22 and the third insulating layer 23, respectively. Between the second insulating layer 22 and the first insulating layer 21 is provided with the first electric field shielding layer 26. The first electric field shielding layer 26 is printed on an upper surface of the second insulating layer 22 or a lower surface of the first insulating layer 21, and then the second insulating layer 22 and the first insulating layer 21 are pressed together.

(9) A lower surface of the third insulating layer 23 is provided with the second heating body 29. A lower surface of the second heating body 29 is provided with the fourth insulating layer 24. Between the fourth insulating layer 24 and the fifth insulating layer 25 is provided with the second electric field shielding layer 27. The second electric field shielding layer 27 is printed on a lower surface of the fourth insulating layer 24 or an upper surface of the fifth insulating layer 25, and then the fourth insulating layer 24 and the fifth insulating layer 25 are pressed together.

(10) Materials for the first electric field shielding layer 26 and the second electric field shielding layer 27 are aluminum foil, copper foil, silver paste, conductive carbon black, conductive nickel black or graphene. The material for the first electric field shielding layer 26 and the second electric field shielding layer 27 is preferably copper foil. Through the arrangement of the first electric field shielding layer 26 and the second electric field shielding layer 27, electric field radiation generated by the heating plates is absorbed, and then guided into the ground through a ground wire.

(11) The first insulating layer 21, the second insulating layer 22, the third insulating layer 23, the fourth insulating layer 24 and the fifth insulating layer 25 are epoxy resin boards or PET (polyethylene terephthalate). A material of the first insulating layer 21, the second insulating layer 22, the third insulating layer 23, the fourth insulating layer 24 and the fifth insulating layer 25 is preferably the epoxy resin board with a remarkable insulating effect.

(12) The first insulating layer 21 has concave points 21a or/and convex points 21b. The concave points 21a or convex points 21b are hemispherical and are evenly distributed on a surface of the first insulating layer 21. Through the arrangement of the concave points 21a or/and convex points 21b on the first insulating layer 21 (a working face) of the heating plate, a heating area of the heating plate is effectively increased, and the concave points 21a and convex points 21b can achieve the effect of health care and massage.

(13) The shielding line 3 comprises a stranded power wire 31, an electric field absorbing shielding layer 32 and a wire insulating layer 33. The stranded power wire 31 is wrapped by the electric field absorbing shielding layer 32; and the electric field absorbing shielding layer 32 is wrapped by the wire insulating layer 33. The electric field absorbing shielding layer 32 is aluminum foil or a metal net, thus effectively shielding electric field radiation generated by wires. The stranded power wire 31 is formed with stranded wires, so as to shield electromagnetic wave radiation generated by wires.

(14) The wire insulating layer 33 is sleeved with a shielding pipe sleeve 34 which is a metal pipe, a metal corrugated pipe, aluminum foil or copper foil and is used for shielding electric field radiation. Or, an outer surface of the wire insulating layer 33 is coated with conductive carbon black, conductive nickel black or graphene so as to also shield electric field radiation.

(15) To sum up, the infrared sauna room with a low electric field and low electromagnetic wave radiation provided by the present invention has the following advantages:

(16) 1. through the arrangement of the first electric field shielding layer and the second electric field shielding layer, radiation generated by electric fields of the heating plates is absorbed, and then guided into the ground through a ground wire;

(17) 2. since the sinusoidal alternating currents of the two heating bodies have phases opposite to each other, electromagnetic waves generated by the two heating bodies have phases opposite to each other; and when the two waves are overlapped, electromagnetic wave radiation is effectively removed via offset; and

(18) 3. electric field radiation generated by wires is absorbed by a shielding material, and then guided into the ground through the ground wire; and the effect of electromagnetic wave radiation shielding is achieved when the wire and stranded wire are twisted.

(19) The embodiments of the present invention are only described above, and is not intended to limit patent scope of the invention. All equivalent structures or equivalent control flow variations made by using the description of the present invention, or direct or indirect adoption of the present invention in other relevant technical fields are thereby within the protection scope for the present invention.
