Description
Technical Field
The utility model relates to a safety device with oxygen boosting.
Background
At present, the outgoing activities become necessary for people, but at present, some protective measures are needed to ensure the safety of people when people go out in an epidemic situation, for example, the mask is worn to prevent external viruses and bacteria from entering the oral cavity of people to cause bacteria and virus infection, generally speaking, the mask is made of non-woven fabric materials, and the medical protective mask, N95 mask is generally of a multilayer structure, also called SMS structure, and has a 3-layer structure, SMS (2S layers and 1M layer), S represents a spun-bonded layer, the diameter is about 20 μ M, the main function is to support the mask structure, the blocking effect is not large, M represents a blocking layer, the most important structure of the mask, the diameter is about 2 μ M, and the most important function is played in blocking bacteria, viruses and blood permeation. The melt-blown layer (spun-bonded layer), commonly called the 'heart' of the mask, is a filtering layer and a blocking layer in the middle of the mask and can filter bacteria and prevent germs from spreading. The melt-blown fabric is a film made of polypropylene with a high melt index and formed by laminating a plurality of criss-cross fibers in random directions, the diameter of the fibers ranges from 0.5 to 10 micrometers, and the diameter of the fibers is about one-thirtieth of that of hair.
However, when the user wears the mask for a long time, the following problems occur:
first, the respiratory resistance problem. The mask with certain protection capability is of a layered structure, but the mask with better protection effect generally has more layers and larger breathing resistance, which affects the breathing of human body, and particularly causes more difficulty in breathing for people with respiratory diseases.
Secondly, for the people who have been infected with pathogens, the mask can prevent the people from being infected with pathogens again, but the viruses can be sucked back to the body, the disease condition can be aggravated by repeated infection, and even the people are in danger of death due to transitional immunity.
Thirdly, the mask is not suitable for all people in all countries of the world, and the mask is not allowed to be worn due to religion and legal restrictions in part of regions, so that inconvenience is brought, and the purpose of protecting the mask worn by people is difficult to achieve even in the period of epidemic diseases.
Fourth, when wearing the mask, whatever mask is in a negative pressure state when breathing in, under the negative pressure state, the tightness of the edge of the mask is difficult to ensure, the edge is easy to leak air, and if the surrounding environment has pathogens, the risk of infection still exists.
Fifthly, due to easy air leakage, the mask belt needs to be pulled tightly by a user, facial indentations, even blisters, skin allergy, exfoliation and skin injury are easy to occur when the mask is worn for a long time, the possibility of infection is directly increased, and the risk of infection still exists, especially for medical care.
Sixthly, present gauze mask does not all have the function of eye protection, and the gauze mask of wearing has only played the virus that blocks of respiratory track, and eyes still expose outside this moment, and eyes also have the mucosa structure, expose and be very easily infect in the pathogen environment, also be the place of key protection. Therefore, the goggles are required to be worn to protect the eyes, but the wearing difficulty of the goggles is higher, and the comfort is poorer.
Seventh, if the mask is worn in summer, it is very hot, and it is easy to wet the mask due to sweating, which may cause unsmooth ventilation and even heatstroke. It is also a fact that the protection ability of the mask is reduced after being wetted.
Eighth, after wearing the mask, both speech communication and breathing are affected by different degrees, which brings inconvenience to daily work and life.
Ninth, wearing the mask increases the sensitivity of the person to temperature, and the difficulty and comfort of wearing the mask when the temperature rises are very poor. .
Tenth, even in pathogen free environments, increased particulate matter in the air due to environmental pollution requires protection from the frequent use of a mask.
When people go out outdoors in summer or winter, the temperature of the environment in which the people are in air is too high or too low, the people are very uncomfortable, and the requirement of regulating the temperature of the sucked air exists. This need has led to the replacement of miniature electric fans with many generations of products, but there has been a lack of a means to effectively regulate the breathing and facial air environment.
Therefore, it is necessary to change the above situation to protect the safety of people going out and to provide comfort.
