The present invention relates to a device capable of filtering fine dust by using a piezoelectric element. More specifically, the device comprises: a frame (100); a piezoelectric element unit (112) prepared on one of the bottom side of the frame (100); a vibration plate (111) prepared on the front end inside the piezoelectric element unit (112); a spring (113) prepared on both sides of the vibration plate (111); a vibration pendulum (114) prepared in the middle of the spring (113); a mutation circuit (211) connected to the rear side of the piezoelectric element unit (112); a conversion coil (212) comprising a conversion coil and stabilizer, while arranged inside the mutation circuit (211); a battery (300) prepared on the bottom on the frame (100); a fan (400) prepared on the top of the frame (100); an air-transfer pipe (401) separately prepared on one side of the fan (400); a first filtering device (501) separately prepared on one side of the air-transfer pipe (401) to correspond to the fan (400); a turbine (510) prepared inside the first filtering device (501) while having a vertically connected axis and being connected to a filter motor (502) on the top; an outlet (550) prepared on the bottom of the first filtering device (501); a second filtering device (601) separately prepared on one side of the first filtering device (501); CMS (610) prepared inside the second filtering device (601); and a discharging unit (650) on the top of the second filtering device (601). Thereby, even without a power supply, a self-power generation enables the prevention of damages due to fine dust. |
