Patent attributes
An electrification apparatus for dust collection includes an electrification module configured to generate an ion emitted to air and comprising: at least one discharge tip configured to emit the ion in a direction opposite to a flow direction of the air, at least one tip holder supporting the discharge tip, a conductive plate generating a potential difference with the discharge tip, and a frame defining an appearance of the electrification module and supporting the tip holder and the conductive plate. The frame comprises an upper frame disposed at an upper side of the conductive plate and a lower frame disposed at a lower side of the conductive plate, the tip holder is disposed between the upper frame and the lower frame, and an upper surface of the tip holder is coupled to the upper frame and a lower surface of the tip holder is coupled to the lower frame.
