Description

Technical Field

[0001] The utility model relates to the technical field of disinfection machines, and particularly to a light leakage prevention structure of a disinfection machine. Background Technique

[0002] Ultraviolet light sources are commonly used components in air disinfection machines and have been widely applied in various disinfection and sterilization machines. For example, a disinfection device for maternal and child products disclosed in the utility model patent with Chinese patent number CN202021046654.5 includes a cabinet body and a cabinet door. One side of the cabinet body is slidably installed with the cabinet door. A plurality of placement plates are installed in the cabinet body. A gap for ventilation is left between the bottom end of the placement plate and the inner wall of the cabinet body away from the cabinet door. An air internal circulation device is installed on the inner wall of the cabinet body away from the cabinet door. The air internal circulation device with the above structure includes a housing. Grille-shaped air inlets and air outlets are respectively opened at both ends of the housing. Along the direction from the air inlet towards the air outlet, a circulation fan, a catalytic unit, an ultraviolet lamp, and an odor adsorption mesh plate are sequentially installed inside the housing. The settings of the air inlet and the air outlet facilitate the entry and exit of air into and out of the cabinet body. However, the ultraviolet light generated by the ultraviolet lamp during operation will transmit from the air outlet towards the outside of the cabinet body, not only causing light pollution but also affecting the use texture of the product. In addition, if the product is used in a dark environment (such as at night), the externally transmitted ultraviolet light will also stimulate the user's eyes, causing discomfort to the user and affecting the use experience.
