Problems solved by technology

[0004] Most of the existing filter materials are mainly made of non-woven fabrics, gauze, etc. The filter element is made of two layers of non-woven fabrics with a layer of very thin melt-blown non-woven fabrics in the middle, and some also add a layer of activated carbon or Made of PTFE layer, its weaving or mesh is relatively large, it can only simply block large particles such as droplets, and has little effect on viruses with a particle size of 100nm

Abstract

The invention belongs to the technical field of protective masks, and particularly relates to a novel coronavirus protective headgear. The structure of the protective headgear is similar to that of anexisting medical protective headgear; the protective headgear comprises a headgear base body, goggles, a virus filter element mask and the like, the base body is made of a composite efficient protective novel coronavirus material and is composed of two layers of materials, the outer layer is polypropylene spun-bonded non-woven fabric, and the inner layer is a superfine-denier electret melt-blownfiber non-woven fabric; a virus filter element material is of a three-layer structure, the outer layer is made of a polypropylene spun-bonded non-woven fabric, the middle layer is made of a double-layer superfine-denier electret melt-blown fiber non-woven fabric, and the inner layer is made of a polypropylene spun-bonded non-woven fabric. The headgear has a good novel coronavirus filtering effect,can reach the NIOSH (National Institute for Occupational Safety and Health) N95 and N99 standards, and has good air permeability.

Description

technical field [0001] The invention belongs to the technical field of protective masks, and in particular relates to a high-efficiency protective headgear for the novel coronavirus. [0002] technical background [0003] Coronaviruses are a large class of viruses that widely exist in nature. The diameter of the virus particles is 60-120nm, the average diameter is 100nm, and they are spherical or ellipsoidal. The 2019 novel coronavirus (2019-nCoV) is the seventh known coronavirus that can infect humans. Common signs of patients infected with coronavirus include respiratory symptoms, fever, cough, shortness of breath and dyspnea. In more severe cases, infection can lead to pneumonia, severe acute respiratory syndrome, multi-organ failure, and even death. In order to protect the health and safety of themselves and others, the majority of residents wore masks to strengthen virus protection during the epidemic. At the same time, in the process of fighting the epidemic, more th...
