AIR-PURIFYING DEVICE STRUCTURE AND SYSTEM FOR ITS CONTROL Russian patent published in 2022 - IPC B01D46/00 B01D46/52 A61L9/00 

FIELD: air purification.

SUBSTANCE: system for control of an air-purifying device relates to air-purifying devices or air purifiers intended for intake and purification of atmospheric air from dust particles and other impurities, as well as viruses and bacteria. The system for control of the air-purifying device includes a device, to which at least one air quality sensor, a central processor, and a sensor control panel of the air-purifying device are connected. The sensor control panel of the air-purifying device contains at least one button for control of the operation of the air-purifying device, at least one indicator of an air-purifying device state, an air quality indicator, and a slider for switching fan speeds. A section of the control panel under the slider for switching fan speeds of the air-purifying device is divided into at least six sectors, and these sectors are applied to each other at intersection points. Moreover, the device itself contains a fan, air intake and release holes limiting an airflow tract, which passes through at least three stages of air purification. The first purification stage is made in the form of a preliminary filtration mesh. The second stage is made in the form of a highly effective HEPA filter. The third stage is made with the possibility of air disinfection and is located between the first and the second stages of air purification. At the same time, a case of the air-purifying device and stages of air purification have a cylindrical shape.

EFFECT: invention provides for high efficiency of air purification and long-term operation of a highly effective HEPA filter, as well as allows for the creation of a compact smart air-purifying device for use in residential and office premises.
