Abstract

There is provided an independent purification device and a range hood. The range hood includes an air outlet pipe (700). An independent purification device is movably inserted into an air outlet of the air outlet pipe (700). The independent purification device includes a housing (100), a purification filter screen (200), an ionization ozone generator (300) and a UV lamp (400). When the oil fume enters the first filter screen (210), ozone, sulfur dioxide and ammonia gas undergo oxidation and separation to remove odors. When the oil fume enters the air channel (103), the ionization ozone generator (300) removes hazardous substances, bacteria and odors in the air. When the oil fume flows through the UV lamp (400), poisonous substances and bacteria in the air can be additionally removed. Finally, when the oil fume flows through the second filter screen (220), the odorous molecules such as excess ozone, sulfur dioxide and ammonia gas in the air can be further oxidized and separated so as to exhaust clean and fresh air, achieving good filtering purifying effect. After a long time of use, the independent purification device can be easily dismounted and changed, improving the purifying effect.

Description

TECHNICAL FIELD The present disclosure relates to the technical field of range hoods, and in particular to an independent purification device and a range hood. BACKGROUND The range hoods are a common appliance in kitchens and the oil fume purifiers can purify oil fume to remove hazardous substances in the oil fume. For example, the substances such as PM2.5, benzene and bacteria in the oil fume can be removed by the oil fume purifiers to make the gases exhausted by the oil fume purifiers cleaner and safer. However, the existing oil fume purifiers are usually integrated with the range hoods, making it impossible to change the oil fume purifiers over a long time of use, thereby affecting purification effect and lowering the user experience. SUMMARY The present disclosure aims to at least address one of the technical problems in the prior arts. For this reason, a first embodiment of the present disclosure provides an independent purification device, including a housing, a purification filter screen, an ionization ozone generator and a UV lamp.
