The disinfection cupboard includes a cabinet body, a cabinet door, a support bracket, a door seal, an electric heater and a germicidal lamp. It is characterized in that the cabinet The body is a horizontal cuboid, and the cabinet door is a double sliding door. Each cabinet door is connected with the cabinet body by cooperating with the upper and lower protruding pins at the contact end of the cabinet side wall and the guide grooves at the upper and lower inner walls of the cabinet body. , two cabinet doors are set at the front end of the guide groove to follow the protruding head. The disinfection cabinet disclosed in this application uses an electric heater and a germicidal lamp in combination to improve efficiency. However, since the effect of using the two alone is not very satisfactory, the cost is increased to a certain extent and the purpose of saving electric energy is not achieved.

Moreover, the heaters, PTC heaters, far-infrared sterilizers, etc. used in the above-mentioned disinfection cabinets all directly install the lamp tubes on the upper or lower part of the inner side wall of the disinfection cabinet to directly sterilize the articles in the disinfection cabinet.
