The present invention relates to an air purifier that maximizes air purification efficiency by collecting and depositing dust and various foreign matters in water. That is, the air purifier of the present invention flows air into the tank where water is stored to continuously supply oxygen to keep the water fresh and to collect and process various dusts, foreign substances and harmful bacteria in the air. However, in order to maximize the collection effect by increasing the surface area where air and water contact by using a bubble, a bubble generator is installed, and a filter is installed in an orbit type between the upper and lower rollers to collect the effect. It is further heightened, UV lamp is additionally installed for the sterilization of harmful bacteria, and the bottom of the tank is characterized by installing a removable net. The air purifier of the present invention has one or more bubble-generators installed inside the tank to circulate and supply bubbles, and the filter is driven in an endless track between the up and down rollers to increase the surface area between water and air, and The filter can be contacted at the same time to maximize the collection effect by quickly filtering the dust and foreign substances in the air, and it is hygienic by sterilizing harmful bacteria, and the removable net is installed at the bottom of the tank to remove foreign substances such as dust. It is possible to create a pleasant and healthy indoor environment by preventing collection and drifting in the tank.본 고안은 공기 중의 먼지나 각종 이물 등을 물속에 포집, 침전토록 하여 공기정화 효율을 극대화토록 한 공기정화기에 관한 것이다.즉, 본 고안의 공기정화기는 물이 저수된 수조 내부로 공기를 유입시켜 지속적으로 산소를 공급하여 물을 신선한 상태로 유지를 시키는 동시에 공기 중의 각종 먼지나 이물, 유해세균을 포집, 처리할 수 있도록 하되, 버블(bubble)을 이용하여 공기와 물이 접촉하는 표면적을 증대시켜 포집효과를 보다 극대화토록 하기 위해 버블-제네레이터를 설치하고, 상하 로울러 사이에 무한궤도형으로 필터를 추가 설치하여 포집효과를 더욱 높이도록 하였으며, 유해세균의 살균을 위해 자외선램프를 추가 설치하며, 수조 밑바닥에는 착탈 가능한 그물망을 설치한 것을 특징으로 한다.이와 같은 본 고안의 공기정화기는 버블-제네레이터를 수조 내부에 하나 이상 설치하여 버블을 순환 공급토록 하고, 필터를 상하 로울러 사이에
