The present application belongs to the technical field of oil fume purification, and particularly relates to an internal circulation oil fume air purifier. In the use of the existing internal circulation oil fume air purifier, oil fume is directly sucked and then purified before being discharged, which leads to poor oil fume purification effect, and thus the discharged oil fume cannot meet the smoke emission standard. The present application proposes the following scheme, which comprises a shell, an installation groove is formed in the interior of the shell, and a slitting adsorption assembly is arranged in the interior of the installation groove. The slitting adsorption assembly comprises a driving motor and a ventilation rack, and a partition rod is fixedly connected to the opposite side of each ventilation rack at equal distances, and an installation hole one is formed in one side of each partition rod. The disclosed internal circulation oil fume air purifier has the beneficial effects of avoiding direct purification of the sucked oil fume, improving the oil fume purification effect, and making the discharged oil fume meet the emission standard.

The invention provides a neck-hung air purifier, and relates to the technical field of air purifiers.
