Far-infrared irradiation device for middle ear and inner ear and far-infrared irradiation earmuff

A far-infrared irradiation device for a middle ear and an inner ear, comprising a conical element (1), a heating component (3.3) and a waveguide (2), wherein a large opening (1.1) and a small opening (1.2) are respectively arranged at two axial ends of the conical element (1), a conical surface (1.4) is formed between the large opening (1.1) and the small opening (1.2), and the conical element (1) is connected to the waveguide (2) through the small opening (1.2), characterized in that:

• the large opening (1.1) of the conical element (1) is provided with a first far-infrared ray emitter (3) for emitting far-infrared rays that converge from the large opening (1.1) toward the small opening (1.2), and the conical surface (1.4) is provided with a second far-infrared ray emitter (4) for emitting far-infrared rays that diffuse outward from the conical surface (1.4);
• the first far-infrared ray emitter (3) comprises a metal sheet (3.1) and a first far-infrared radiation film (3.2), wherein the metal sheet (3.1) is in contact with the conical element (1), and the first far-infrared radiation film (3.2) is arranged on a side of the metal sheet (3.1) close to the large opening (1.1);
• the heating component (3.3) is arranged on the other side of the metal sheet (3.1) and is used to heat the metal sheet (3.1) so that the first far-infrared radiation film (3.2) is heated to emit far-infrared rays;
• and
• the second far-infrared ray emitter (4) comprises a second far-infrared radiation film (4.1) arranged on an outer surface of the conical surface (1.4) of the conical element (1), wherein the second far-infrared radiation film (4.1) is heated by the heat transmitted from the metal sheet (3.1) through the conical element (1) to emit far-infrared rays.
