AIR RECIRCULATOR Russian patent published in 2023 - IPC A61L9/20 

FIELD: medical equipment; air humidifier.

SUBSTANCE: air recirculator contains a housing inside which a UV radiation source, a filter and a fan are installed. The recirculator is equipped with modules fixedly installed among themselves so that a helical channel is formed inside them, and with a reflective plate installed in the housing. The inner surface of each module has a cylindrical shape and is provided with a helical surface, in the center of which there is a hole for installing a UV radiation source. The screw channel goes around the source of UV radiation and is covered with a reflective layer. The filter configured to capture decontaminated particles of air pollution from the screw channel and the fan with an outlet pipe, configured to supply air from the screw channel to the room, are removable and installed in the outlet part of the housing. The reflective plate is made and located in such a way that the air taken from the room with the help of a fan, entering the housing, goes around the reflective plate and enters the screw channel.

EFFECT: ensuring sufficient time for continuous exposure to ultraviolet radiation on viruses and pollution particles, which leads to an increase in the efficiency of disinfection of air and pollution particles in the air inside the recirculator, and to a reduction in the dimensions of the device.
