Efficient haze filtering nuclear pore membrane filter and efficient haze filtering nuclear pore membrane respirator

Abstract

The invention discloses an efficient haze filtering nuclear pore membrane filter and an efficient haze filtering nuclear pore membrane respirator. The filter comprises a nuclear pore filter membrane and a support mesh, wherein the nuclear pore filter membrane and the support mesh are stacked and connected together; the efficient haze filtering nuclear pore membrane respirator comprises a respirator body; the respirator body comprises an inner layer body and an outer layer body which are permeable; the edges of the inner layer body and the outer layer body are connected, so that an interlayer is formed between the inner layer body and the outer layer body; openings are formed in the edges of the inner layer body and the outer layer body; at least one efficient haze filtering nuclear pore membrane filter is arranged in the interlayer through the openings. The efficient haze filtering nuclear pore membrane filter and the efficient haze filtering nuclear pore membrane respirator are simple in structure and convenient to use; a good effect of effectively filtering thin particle matters of PM (Particle Matter) 2.5.

Description

technical field [0001] The invention relates to a mask, in particular to a high-efficiency haze-filtering nuclear pore membrane filter sheet and a high-efficiency haze-filtering nuclear-pore membrane mask. Background technique [0002] Environmental deterioration caused by severe industrial pollution and excessive resource consumption has formed an irreversible climate anomaly. The large amount of pollutant discharge and abnormal climate conditions that are not conducive to pollutant discharge are the main factors for the occurrence of large-scale and high-frequency haze weather in densely populated areas in my country. Fine particulate matter with a size of less than 2.5 microns, namely PM2.5, poses a serious threat to human health and cannot be ignored. [0003] Masks are an effective means of protection to prevent pollutants from entering the human body through the respiratory tract when people travel. All countries have clear national standards for dust respiratory pro...

Problems solved by technology

Although there are many types of masks, masks that can meet the above-mentioned national standards, fit closely to the face (no side leakage) and be comfortable to wear (small air resistance, hygienic wearing, and easy maintenance) are rare.
