Document Type and Number:
WIPO Patent Application WO/2021/196355
Kind Code:
A1
Abstract:
A rotary air purification device. A porous purification dust filtering core sleeve (10) is used for filtering, improving the filtering capacity and facilitating the cleaning; the porous purification dust filtering core sleeve (10) comprises a cylindrical main body portion and a wedge-shaped portion (11) for dust removal, a tapered cavity (12) is provided between two or more adjacent tapered structures, a dust removal spring set is provided between tip portions of every two adjacent tapered structures, the dust removal spring set is used for cleaning dust on the porous purification dust filtering core sleeve (10), achieving the cleaning of the porous purification dust filtering core sleeve (10); furthermore, as most of the dust is accumulated at the wedge-shaped tip structure of the porous purification dust filtering core sleeve (10), the dust at the wedge-shaped tip structure of the porous purification dust filtering core sleeve (10) can be conveniently cleaned by shaking the dust removal spring set, and the dust removal spring set only needs to be slightly shaked due to the less dust at the cylindrical portion thereof, not causing the deformation of the porous purification dust filtering core sleeve, and ensuring the purification capacity of the purification device.
