The sterilization identification mechanism comprises a containing cavity, an
ultraviolet sterilization lamp is arranged on the wall face of the containing cavity, the illumination direction of the
ultraviolet sterilization lamp faces the interior of the containing cavity, at least part of a wall face shell in the position, located in the illumination area of the
ultraviolet sterilization lamp, of the interior of the containing cavity is made of photochromic shell materials, and the ultraviolet sterilization lamp is arranged in the containing cavity. According to the utility model, when
ultraviolet light with a specific
wavelength irradiates on the accommodating cavity shell, the accommodating cavity shell can generate color change, and the color is changed into another color, so that a user can intuitively judge whether the ultraviolet sterilization equipment can realize bacterium sterilization operation or not through naked eyes, and when the
ultraviolet light disappears or is not in a specific sterilization
wavelength range, the ultraviolet sterilization equipment can be used for sterilizing
bacteria. When the ultraviolet sterilization equipment works, the color of the accommodating cavity shell can be automatically changed into the
normal color, so that the sterilization identification mechanism can be used for simply and accurately identifying the sterilization effect of the ultraviolet sterilization equipment during working, convenience can be brought to the life of people, and potential health hazards can be effectively avoided.
