Motorized Air Filter Mask

Abstract

Disclosed is a motor engine-driven air filtering mask. A gas path system of the motor-driven air filtering mask is composed of an air outlet, a valve structure, an air outlet pipe, an air outlet filter, an air storage bag, an air pressure sensor, a safety valve, a high-pressure pipe, an inflating pump, a low-pressure pipe and an air inlet filter. The motor engine-driven air filtering mask can achieve a collaborative function with a wearer through a control circuit and the valve structure, and enables the wearer to inhale clean air.

Description

technical field [0001] The invention relates to a portable motorized air filter device. Background technique [0002] With the development of the economy and the progress of society, the level of civilization of human life has been continuously improved, and people's work, study, entertainment and other activities are mostly realized through travel, but the incidence of some "urban diseases" and "modern civilization diseases" is gradually increasing , of which poor air quality is a major factor, while motor vehicles, construction sites, factories, and household appliances are the four major sources of air pollution. Motor vehicle exhaust, dust transported over medium and long distances, and biomass burning are the main sources of urban air pollution in my country. The number of fuel vehicles in cities is increasing day by day, and the harmful gases in cities with engine exhaust as the main component are becoming denser and denser, and the streets and alleys are shrouded in ...

AI Technical Summary

Problems solved by technology

On the one hand, it is due to the expansion of PM2.5 and fine particulate pollution components in the atmosphere. On the other hand, the current masks are all passive filters and do not have the ability to filter medium and fine particulate matter.

Because it is a passive filter, if measures such as densification and thickening of fabrics are used to improve its ability to filter fine particles, it will also cause breathing difficulties
