Humidifier having uv led

PURPOSE: A humidifier with an ultraviolet light emitting diode(UV LED) is provided to sterilize a vibrator and water near the vibrator and stably supply power to a UV LED module. CONSTITUTION: A humidifier includes a storage tank, a vibrator, a discharge nozzle, a first UV LED module(200A), an aerosol flowing pipe(21), a first electrode(421), a second electrode(22), and a power supply part. The vibrator allows water flown out from the storage tank to aerosolize. The discharge nozzle discharges the water aerosolized by the vibrator to the outdoor air. The first UV LED module is located inside the discharge nozzle in a direction toward the vibrator and sterilizes the water aerosolized by the vibrator before the water is discharged through the discharge nozzle. The aerosol flowing pipe is located between the vibrator and the discharge nozzle to form at least a part of flowing passage of the aerosolized water. The first electrode is extended from the first UV LED module and located in one end of the discharge nozzle. The second electrode is electrically contacted with the first electrode. The power supply unit supplies power to the second electrode.
