Problem to be solved: to provide an ozone generator capable of reducing the ozone concentration to the reference value below the nozzle of the ozone generator, preventing ozone peculiar unpleasant odor, and mixing the ozone generated with the ozone and the ultrasonic humidifier to produce the synergistic effect of humidification and sterilization.The ozone concentration at the outlet of the ozone generator was instantaneously thinned by connecting the ejector (20) to the outlet of the ozone generator to attract the outside air, thereby eliminating the high concentration ozone region.A steam mixer is connected to the ejector, and the vapor of the ultrasonic humidifier is sucked so that ozone and steam can be emitted.In addition, a clean indoor space in which the aroma drifts in the room using the emulsion of Essen tea oil in the ultrasonic humidifier water was realized.Diagram【課題】オゾン発生器の噴出口近辺でオゾン濃度を基準値以下に低減し、オゾン特有の不快臭を防ぎ、又、オゾンと超音波加湿器で生成する蒸気を効率よく混合して加湿と殺菌の相乗効果を生み出す、オゾン発生器の提供。【解決手段】オゾン発生器の出口にエジェクター(20)を連結して、外気を吸引することで、オゾン発生器出口のオゾン濃度を瞬間的に薄め、高濃度オゾン領域を解消した。又、エジェクターに蒸気混合器を連結し、超音波加湿器の蒸気を吸引し、オゾンと蒸気を放出できるようにした。又、超音波加湿器の水にエッセンシャルオイルのエマルジョンを使用して室内に芳香が漂う清浄な室内空間を具現化した。【選択図】図1
