Description

A kind of anti-smog mask

technical field

The utility model relates to an anti-haze mask, which belongs to the technical fields of sanitation and chemical industry.

Background technique

As the quality of life of modern people is improving day by day, they pay more and more attention to the environment, and have higher and higher requirements for physical health. While improving the existing environmental pollution, how to protect themselves is a question that everyone thinks about, " Wear a mask when you go out" has become a common reminder for family and friends.

According to modern research, there are a large number of large and small dust particles in the air. These particles are not only the source of air pollution, but also the carrier of pollutants. These particles can carry a large amount of bacteria, viruses, heavy metals, chemical substances, etc., and scatter everywhere with the air flow, posing a huge threat to people's health. According to statistics, 500,000 people die prematurely every year due to air pollution in China. It is imperative to protect the environment and health.

Haze is also called haze. Particles such as dust, sulfuric acid, nitric acid, and organic hydrocarbons in the air make the atmosphere cloudy, blur the vision and cause visibility to deteriorate. If the horizontal visibility is <10000m, the aerosol composed of this non-aqueous substance The visual range obstacle caused by the system is called Haze, Dust-haze or Haze. The English abbreviation of particulate matter is PM. Beijing, China monitors fine particulate matter (PM2.5), that is, pollutant particles with an aerodynamic equivalent diameter of ≤2.5 μm. The particle itself is not only a pollutant, but also a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons, which are the main substances that rapidly damage the human body. Therefore, the control of haze is of great significance. It can be said that controlling the inhalation of haze is equivalent to controlling the inhalation of most pollutants. Bacteria and viruses can either attach to these haze particles and scatter everywhere, or they can flow with the air by themselves. The size of bacteria is generally 0.5-5 μm, which is comparable to the size of haze. The size of viruses is smaller, generally 30-300nm. The effective filtration of smog, dust, particles, bacteria and viruses, the effective purification of breathing air, the basic guarantee for human health and the improvement of health and happiness index are of great significance.

As an individual in society, reducing environmental pollution and stopping others from destroying the environment can effectively promote the improvement of the environment and the improvement of health quality. At the same time, what should be done is to pay attention to personal protective measures. In a polluted environment, how to avoid or reduce the invasion of harmful substances on the health is a problem worthy of attention.

At present, there are many kinds of masks on the market. The main principle is barrier and adsorption. There is a dilemma between ventilation and purification. The ventilation is good, but the pore size is too large to purify the air; the pore size is small, and the air is purified. The effect is relatively improved, but it cannot breathe well, causing the wearer to breathe unsmoothly, or even give up wearing a mask, which does not have due protective effect on people's health. For example, the Chinese Utility Model Patent Application No. 201410490840.0 "An anti-smog mask with dual functions of filtration and adsorption based on nanostructures" also has a dilemma between ventilation and purification. This patent uses a relatively new material process method, which can produce a mask with better purification effect, but its purification principle is unclear, the process method is unclear, and the air that people breathe has a certain humidity. The working principle of electrostatic adsorption is In a dry environment, it no longer has this ability to act in a humid environment, so the effect of purifying the air cannot be achieved. Another example is "A Polysaccharide Composite Fiber Material and Its Preparation Method, Filter Sheet and Mask" with the Chinese Utility Model Patent Application No. 201410520393.9. Just rely on the simple barrier of material fibers. In addition, some protective masks can indeed block more than 95% of sub-micron particles. The basic principle is that the barrier effect is only based on the barrier effect of the material. The barrier effect is good but the respiratory impedance is high, so it is not suitable for ordinary people to wear for a long time. Therefore, how to find a protective mask that has a strong protective effect and can reduce respiratory resistance is a topic worth studying.

The utility model considers the dual effects of ventilation and purification, and increases the air permeability by increasing the aperture of the ventilation mesh. It is effective in both dry and humid air environments, and can adapt to changes in different environments, thereby purifying the air. The utility model has a novel design principle and a clear process method, and is worthy of market promotion.
