Description

Novel external power air supply gauze mask

Technical Field

The invention relates to the field of masks, in particular to a novel external power air supply mask.

Background

The traditional mask is usually made of a filtering material for preventing particles, and is fixed on the head by means of a bandage, an ear band and the like, a mask body forms a space isolated from polluted air in the mouth and nose areas of a person, the polluted air is forced to enter a respiratory tract after being filtered by the mask filtering material by means of human body inspiration, and waste gas is exhausted through a filtering layer after breathing, the purpose of the process is to isolate the pathogenic bacteria of the external environment and the oral cavity system, but the existing masks and the existing schemes have great defects, the problems of safety, comfort and reusability cannot be solved by a common mask, the mask is very stuffy when being worn in hot days, the oxygen content of the air in the mask is greatly reduced, the breathing is difficult and anoxic, and the mask has great harm to the lung and the brain of the human body (especially to special crowds such as children, patients, fat people and the like), meanwhile, if a breather valve is used, the pathogenic bacteria and dust can be easily, and the life of traditional gauze mask is short, and most medical gauze masks can't change the part usually, need whole abandonment after the inefficacy, unable used repeatedly to the material like melt-blown cloth and non-woven fabrics to and manpower and medical resource's use causes a large amount of wastes, and present market has multiple ordinary and electronic gauze mask, divide into following kind:

A. disposable medical mask:

1. the mask is sewn by adopting multilayer melt-blown cloth and non-woven fabric, so that germs can be prevented from entering the oral cavity, but the mask has the defects of great defect, poor fitting property, poor sealing effect and low safety, air leakage often occurs at the edge of the mask, particularly in a sealed environment, germs easily enter an oral cavity system by taking a clearance, and the infection probability is great;

2. the cleaning cannot be carried out, the cleaning is basically carried out once or for many times every day, and the waste is great;

KN95 and N95 medical mask:

1. the main working principle is that the respirator is used for multi-layer filtration for a plurality of breaths, the breathing strength is stronger, so that more pollutant particles are adsorbed, the using time is 1 to 3 days under normal conditions, the environment with intensive people flow needs to be replaced once a day, the respirator cannot be cleaned, and the waste is great;

2. the air tightness is good, but the air tightness is easy to cause dyspnea, is not suitable for being worn for a long time, is stuffy and uncomfortable, can generate oxygen deficiency, easily causes respiratory system diseases, and even can generate hypoxia symptoms of old people, children, respiratory disease patients and weak people, so that the intelligence and the respiratory system are damaged;

C. cotton gauze mask: the fabric has good air permeability, is used for keeping warm, can be cleaned, and has extremely poor dustproof and antibacterial effects;

D. an activated carbon mask: can effectively filter bacteria and viruses and can also absorb partial substances such as odor, formaldehyde and the like, but has the defect of extremely poor air permeability and is not suitable for long-time use;

E. 3M dust mask: generally, air is sucked through a filter screen cloth of a mask, waste gas is exhaled through a one-way breather valve, the filter screen only aims at dust, the fitness is good, the dust can be effectively prevented from entering respiratory organs of a human body, the breather valve is one-way breathing, if germs are breathed by the breather valve, pollution and leakage outside the human body can occur, the comfort level is poor, the breathing is difficult, and the breather valve cannot be cleaned;

F. electric respirator: generally use axial flow electric fan, the material uses silica gel, cloth or KN95 gauze mask are leading, through the air feed of filter core, many electric gauze masks all increase the breather valve function, though breathe easily, safety problems such as cross contamination of germ can appear, very many electric gauze masks also have a lot of defects, for example leak out, the noise is big, the air is not enough, the comfort level is poor etc. if adopt KN95 electric gauze mask to use the back in short-term need change whole gauze mask body, can't wash, also can't used repeatedly, it is extravagant big.
