AIR PURIFICATION RECIRCULATOR Russian patent published in 2022 - IPC A61L9/20 

FIELD: air purification.

SUBSTANCE: invention relates to equipment for disinfecting air in private and public vehicles, premises, and products providing an enclosed space. Air purification recirculator comprises a body made with an inlet for the supply of air subject to purification and with an outlet for the release of purified air, an ultraviolet lamp, a fan, a filter, and a control unit, installed in the body, according to the invention, titanium dioxide is applied to the inner surface of the body, an air filter is installed at the inlet of the body, the fan is placed in the body by the inlet, UV emission power control sensors constituting photodetectors, air deflectors with titanium dioxide applied on the plates thereof, a rotation speed sensor of the fan, an air flow speed sensor installed in front of the outlet of the body, a power supply unit powering the fan, sensors, and microprocessor, a current generator linked with the ultraviolet lamp and maintaining the power of UV emission. The power supply unit, fan, current generator, and sensors are therein linked with a microprocessor configured to store the control values of the UV emission power, the input voltage of the fan, the rotation speed of the fan and/or the air flow speed, as well as subsequently monitor the current values of the speed, the rotation speed of the fan, the air flow speed, the UV emission power, and the input voltage of the fan. The microprocessor is also configured to control the adjustment of the rotation speed of the fan, depending on the current value of the UV emission power based on a signal from the rotation speed sensor of the fan and/or the air flow speed sensor, the deflectors are inclined in a vertical and/or horizontal plane, configured to divert the air flow from the area with the lowest UV emission power to the area of greater UV emission power, the microprocessor is linked with a server or processing unit located outside of the body in order to transmit information on the monitored parameters.

EFFECT: increase in the quality of air purification, increase in the stability of operation, expansion of the operating capabilities due to the adjustment of the operating mode depending on the external conditions.
