▎ 摘　　要

NOVELTY - The device has a power supply and DC to AC inverter electrically connected with a direct current high voltage power supply. The direct current high voltage power supply is connected with a graphene magnetic generator to supply direct current voltage to the graphene magnet generator. The graphene magnet generator is provided with a handle and/or a strap in-air inlet (5). An air outlet of the graphene magnet generator is connected with a respiratory mask (15) for human breathing through a gas pipeline (13). USE - Portable-type air particulate matter purifying device. ADVANTAGE - The device prevents harm to people, and has wide range of applications. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a portable-type air particulate matter purifying device. Negative oxygen ion outlet (4) Handle and/or strap in-air inlet (5) Gas pipeline (13) Respiratory mask (15)
