Intelligent disinfecting equipment is an ultralow-volume, intelligent and three-dimensional disinfecting device composed of a medicine applying device, a central control device, an external interaction device, a walking device, a power supply device and a rack. When 5-100 micrometers of ultramicro medicine particles containing effective disinfecting components are conveyed to a disinfecting environment through an airflow conveying device of the disinfecting device, the disinfecting operation process is completed under cooperation of the central control device containing a motion control module, a data module and a task management module, the external interaction device and the power supply device; preparation, analysis and comparison of whole disinfecting operation, environmental meteorological data acquiring and automatic collection, recording, storage and transmission of data of operation control and the operation process can be achieved through the Internet of Things and cloud computing in the disinfecting process; disinfection, management and monitoring are timely and are synchronized and integrated. The intelligent disinfecting equipment saves medicine, water and labor, and automation, standardization, formulation and menulizing of the disinfecting operation can be achieved.
