Novel anti-fog mouth mirror

The utility model relates to a novel antifogging mouth mirror, which comprises a lens substrate layer and a reflecting film I plated on one side surface of the lens substrate layer, and the reflecting film I comprises an Rh layer with the thickness of 98-102nm, an SiO2 layer with the thickness of 68.6-71.4 nm and a TiO2 layer with the thickness of 49-51nm which are sequentially arranged from inside to outside. According to the anti-fog mouth mirror, the reflecting film I consisting of a plurality of film layer structures is arranged on the side surface of the lens substrate layer, so that the anti-fog mouth mirror is high in strength, has an anti-fog effect and is high in reflectivity. Furthermore, a reflecting film II is arranged on the other surface of the lens substrate layer, so that reflection can be enhanced through one surface of the reflecting film I during use, and a user can observe conveniently; reflection of light in the oral cavity is enhanced through one face of the second reflecting film, and t
