Air purification devices are a commonly used air purification method, which can enable the users to breathe cleaner air. The current air purification devices mainly use filtration and adsorption, but the filtration and adsorption technology only concentrates pollutants in the adsorption material. After long-term use, a large amount of dust is likely to accumulate. If not dealt with in time, the accumulated pollutants will cause secondary pollution. In addition, the air purification device usually has an air intake channel on one end face of the housing, with a small air intake and low purification efficiency, and it cannot quickly purify the indoor air. In view of this, we have improved the structure of the air purification device to improve the purification efficiency and at the same time facilitate the cleaning of the accumulated filtration and adsorption substances.
