Function expandable air purification device {Function expandable air purification device}

The present invention relates to an air purifying apparatus capable of expanding functions, and more particularly, to an air purifying apparatus capable of expanding functions by additionally installing a component for purifying air on a control board.

Recently, a variety of electronic control boards that can perform various functions by assembling various types of electronic components on a single board have been released. In particular, as the interest of Single Board Computer (SBC) increases, there are many cases of using single board computers for educational purposes.

A single board computer can perform specific purposes and functions by connecting various sensors, motors, LED lamps, displays, input/output devices, and network interface devices. However, such a single board computer has a dedicated connector to connect general-purpose input/output (GPIO) or module components, and can be used by connecting the components to the GPIO or the dedicated connector.
