Description

People flow disinfection system

This creation is a disinfection system for use in high-traffic areas to further reduce vectors of infection.

Infectious diseases, such as bacteria, fungi or viruses, that travel through the air and through contact with each other cause significant harm to humans. For example, according to Wikipedia, as of March 10, 2023, more than 676 million confirmed cases of severe special infectious pneumonia (Coronavirus disease 2019, COVID-19) have been reported globally, and more than 6.881 million patients have died.

At international airports, there are many passengers from all over the world, making them the main vector for the spread of international infectious diseases, causing the rapid expansion of the epidemic. In order to prevent the invasion of the epidemic, the epidemic prevention work at the airport is particularly important.

The response to infectious diseases of unknown origin is usually to install infrared thermal imaging cameras at airports to strengthen inspection measures for incoming passengers. When the infrared thermal imaging camera detects that the passenger's body core temperature exceeds the set value, a warning is generated. Using an infrared thermal imaging camera to measure body temperature can reduce labor costs and reduce the risk of direct contact. However, due to the low accuracy of infrared thermal imaging cameras, it is necessary to rely on retesting with a highly accurate ear thermometer or forehead thermometer to avoid omissions. In addition, some confirmed cases may not have fever symptoms.

Therefore, a disinfection system suitable for large population flows is also needed to further reduce the vector of infection.

The main purpose of this creation is to provide a disinfection system to further reduce the vector of infection in a fast, effective and economical way.

The fluid delivery system connects the disinfectant storage tank and the plurality of nozzles to deliver disinfectant in the disinfectant storage tank to the nozzles. Multiple brushes are arranged on both sides of the walkway. Multiple motors drive multiple brushes to rotate respectively, and the controller controls the fluid delivery system and the multiple motors.

In one embodiment, the plurality of nozzles are also spaced apart on the left wall and the right wall.

In one embodiment, the number of the disinfectant storage tanks is more than two, and different disinfectants are stored respectively.

In one embodiment, the human flow disinfection system also includes two transmission wheels and a transmission motor. The transmission motor is connected to the controller. The walkway is a crawler track or a belt and engages the two transmission wheels. The transmission motor drives the two transmissions. The wheel spins.

In one embodiment, the controller controls the rotation speed of the transmission motor so that the time for a person to go from the entrance to the exit is a fixed time.

In one embodiment, the entrance further includes a first sensor to detect the entry of a person.

In one embodiment, the exit further includes a second sensor to detect the departure of a person.

According to the disinfection system provided by this invention, the vector of infection can be further reduced in a fast, effective and economical way. Not limited to airports, this disinfection system can also be used in places with high population flow, such as stations, hospitals, buildings, etc.
