1. An electrification apparatus for dust collection, the electrification apparatus comprising:
an electrification module configured to generate ions that are emitted to air,
wherein the electrification module comprises:
a high voltage tip comprising at least one discharge tip configured to emit the ions in a direction opposite to a flow direction of the air,
a conductive plate disposed around the discharge tip and configured to generate an electric potential difference with the discharge tip of the high voltage tip,
a lower frame that mounts the conductive plate and the high voltage tip, and
an upper frame that is coupled to the lower frame, the upper frame covering the conductive plate and the high voltage tip so that the discharge tip is exposed to outward,
wherein the upper frame comprises (i) an upper outer frame that provides a lower frame coupling part for coupling to the lower frame and (ii) an upper inner frame disposed inside the upper outer frame, and
wherein the lower frame provides a coupling hook corresponding to the lower frame coupling part.
