▎ 摘　　要

NOVELTY - Far-infrared spectrum generator comprises a radiation layer, a heating layer and a heat insulation layer. The radiation layer is placed on the radiation surface of the heating layer. The heat insulation layer is placed on the heat insulation surface of the heating layer relative to the radiation layer. The radiation layer is formed by coating the radiation surface of the heating layer with a far-infrared functional coating. The heat insulation layer is formed by coating the heat insulation functional coating on the heat insulation surface of the heating layer relative to the radiation layer. USE - Used as far-infrared spectrum generator. ADVANTAGE - The generator: is economical; has a simple structure, simple to manufacture, remarkable the far infrared function, and antibacterial and air purification effects; radiates far-infrared rays with a wavelength of 6-14 mu m; reaches the normal total emissivity about 0.9; permanently releases negative ions; reduces the loss of far-infrared radiation of the radiation layer and the heating layer; and strengthens the far-infrared radiation effect in the direction of the radiation layer of the far-infrared spectrum generator.
