1. An ionic wind generator comprising:
a power module;
a first electrode configured to receive power from the power module by being connected to the power module to become an emitter electrode and to be a carbon brush comprising multiple carbon fibers; and
a second electrode spaced apart from the first electrode and grounded at the same time of being connected to the power module to become a counter electrode,
wherein the first electrode is installed on a mounting arm part made of an insulating material,
wherein the mounting arm part is disposed at an entrance of a module housing in which the first electrode and the second electrode are installed, and is connected to the module housing,
wherein the first electrode is inserted into a center of the mounting arm part,
wherein a first end of the first electrode protrudes away from the mounting arm part, and a second end of the first electrode protrudes away from the mounting arm part, and
wherein a distance between one of the first end and the second end of the first electrode and the second electrode is variable as the first electrode is moved along the center of the mounting arm part toward the second electrode.
