Title:
AIR PURIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/011985
Kind Code:
A1
Abstract:
An air purification device, comprising a motor (30) and a fixed wheel (20) driven by a shaft of the motor (30). The fixed wheel (20) is divided into an inner ring (21) and an outer ring (22). Between the inner ring (21) and the outer ring (22) is provided a folding filter paper (50). At the periphery of the fixed wheel (20) is provided an air channel casing (40). The air channel casing (40) is fixed to the wheel (20) to form an inflow-outflow air channel. The fixed wheel (20) fixes the filter paper (50), and the filter paper (50) rotates as a wheel blade and utilizes centrifugal speed to push air into an air outflow channel. That is, the filter paper (50) serves as a wheel blade, and at the same time filters air, thereby saving the space that would be occupied by a filter paper, reducing the volume of the air purification device. The air channel casing (40) design improves output air volume.
