Problems solved by technology

Oxygen tanks used by firefighters or divers can provide positive pressure for breathing masks, but the oxygen tanks are heavy and not easy to carry. Oxygen needs to be compressed into the tank through a gas compression device, which is only suitable for special occasions
And usually the gas storage capacity of the oxygen tank is also very limited, which can only meet the breathing needs of the user in a short period of time

Abstract

The invention discloses a portable air purifying filter. The portable air purifying filter comprises a casing, a surrounding part provided with an internal chamber, an external air inlet for receiving environmental air, a filtered air port, a filter element suitable for a replaced filter piece, a fan sucking air into the surrounding part to enable the air to pass through the filter element, and a mask adhered to the nose and the mouth of a user. The mask is connected with the casing through a flexible tube body. The filter is simple in structure, convenient to carry about, capable of preventing suspended particles in the air, especially PM2.5, epidemic infectious virus and other injurant from entering a human body and severely jeopardizing the health, obvious in effect and comfortable in wearing and use, and is suitable for the old, children and people performing urban outdoor work for long period of time.

Description

Technical field [0001] The invention relates to a respirator device, in particular to a portable air purification filter equipped with a power device. Background technique [0002] Air pollution is the pollution of the atmosphere caused by substances that endanger human health and the surrounding environment. These substances may be gas, solid or liquid suspended matter, etc. The smog that appears in a large area in China is a serious pollution phenomenon caused by solid or liquid suspended matter formed by dust, sulfuric acid, nitric acid, organic hydrocarbons, etc. and small water droplets in the air. [0003] Suspended matter is usually distinguished by particle size, and the respirable suspended particles can affect human health. Suspended particulate matter, in environmental science, specifically refers to solid particles or droplets suspended in the air, and is one of the main sources of air pollution. Among them, particles with an aerodynamic diameter (hereinafter referre...
