▎ 摘　　要

NOVELTY - The device has a box body (1), whose top end is provided with a water inlet (7). An end of the box body is provided with a fixing block (8). A side of the box body is provided with a second exhaust pipe (6). A side of the second exhaust pipe is provided with a shell (5). An end of the shell is provided with a first exhaust pipe. An inner side of the shell is provided with an active carbon filter screen. An inner side of the first exhaust pipe is provided with an exhaust fan. An outer side of the box body is fixed with a handle and a supporting frame. USE - Filter device using graphene ultra-filtration membrane. ADVANTAGE - The device is provided with an active carbon filter screen, an exhaust fan, through the operation of the exhaust fan, the air in the box body passes through the active carbon filter screen, and is discharged through one end of the first exhaust pipe, so as to make the active carbon filter screen to purify the air in the box body. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of filter device using graphene ultra-filtration membrane.
