▎ 摘　　要

NOVELTY - The device has a central guide plate (2) fixedly connected at a middle position of a bottom part of an inner cavity of a protective shell (1). A symmetrical guide plate (3) is fixedly connected at two sides of the central guide plate. An inner wall of the inner cavity of the protective shell is fixedly connected with a primary filter layer (4). A left side outer wall of the central guide plate is fixedly connected with a graphene filtering layer (5). An outer wall of a right side of the central guide plate is fixedly connected with a photo-catalyst purifying layer (7). An outer wall of the protection shell is provided with a passageway (15). USE - Graphene air filtering device. ADVANTAGE - The device can effectively prolong way of air movement to enhance filtering effect, assist adjustment of air humidity and temperature through an atomization section, make comfortable environment, and place a fan at an inner side of a filter to avoid dust contamination and prolong service life of the device. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a graphene air filtering device.
