Description

Portable air filtering and purifying device Technical Field The utility model relates to the technical field of purifying devices, in particular to a portable air filtering and purifying device. Background It is known that in industrial production, a large amount of substances polluting the air, such as dust or smoke, are generated during the processing and production of some special materials, such as welding, and an air filtering and purifying device is needed. At present, for an air filtering and purifying device, such as a wearable haze preventer disclosed in patent number CN201520509342.6, the key point is to set up anions, but only to set up thinness for a filter core, because the conventional filter core is stacked at the air inlet of a blower, if too thick, the whole design is thicker, and the carrying is not facilitated.
