Abstract:Objective To design a rapid intelligent fogging disinfection device as an emergency disinfection equipment to deal with
the large-scale and highly infectious epidemic situation that may occur at any time in the future. Methods Hypochlorite water which
was food-grade was selected as the disinfectant for the source of fogging. The mechanical components of the device was constructed
by using stainless steel square bar, storage tank, water pump, PVC pipeline, and four-way fogging nozzle. The device circuit and
software control were implemented by using passive infrared detectors (PIR), microcontroller, relay, raspberry pie, and camera
module. Results When the PIR recognized that someone entered the entrance of the disinfection device, it sent out a identification
signal, which was transmitted to the microcontroller control system, and the water pump was controlled to run for 15 s by the relay.
The hypochlorite water in the pumped storage tank could generate mist through the four-way fogging nozzle, which could disinfect
pedestrians from head to foot for 15 s, and protect them from germs for a long time. At the same time, the device could use the
camera to take pictures of entering pedestrians and upload them to the background for real-time viewing and personnel statistics
by PC and mobile terminal devices. Conclusion The design can be productization and standardized to serve the improvement of
disinfection protection capacity, and provide strong support for effective response to major public health events, disaster relief, and
epidemic prevention in China.
