Description

Mask with blower fan installed {MASK WITH BLAST FAN}

The present invention relates to a mask equipped with a blowing fan to make breathing easier, and more particularly, to a mask equipped with a blowing fan to facilitate the flow of air passing through a filter membrane filtering air.

Unlike the past, modern people are threatened with respiratory health by various harmful gases, yellow dust, and fine dust. This is a phenomenon that mankind is experiencing as we enter the industrialization era, and air pollution tends to intensify in proportion to the development of industry and the benefits of cities.

The causes of air pollution are divided into natural ones, such as desert sandstorms and volcanic eruptions, and artificial ones, such as factory waste gases and fuel combustion.

Normally, natural contaminants are generated by natural physiology and do not pose a lasting threat to human respiratory health because they are generated temporarily. However, artificial pollutants are emitted from fuel combustion, nuclear energy generation using nuclear power, chemical reactions, physical processes, automobiles, aircraft, etc. The main cause is various pollutants generated during fuel combustion, and human respiratory health has a lasting adverse effect on

Of these, carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2) account for a high proportion. In particular, sulfur dioxide (SO2) reacts with other air pollutants to create additional secondary pollutants.

Carbon monoxide is a colorless, odorless, toxic gas that is generated when carbon in fuel is incompletely burned. The sources are mainly vehicles, natural sources such as fuel combustion in factories and forest fires, and indoor sources such as kitchens, cigarette smoke, and district heating.

The nitrogen dioxide is a reddish-brown highly reactive gas, which is generated by the oxidation of nitrogen monoxide in the air, and serves as a precursor for generating ozone by reacting with volatile organic compounds in the air. The main emission sources are automobiles, high-temperature combustion processes, and chemical manufacturing processes, and are caused by natural phenomena produced by bacteria in the soil.

The sulfurous acid gas is a kind of sulfur oxide, which is easily soluble in water, colorless, and nonflammable gas having a pungent odor. It exists in volcanoes and hot springs and reacts with hydrogen sulfide to produce sulfur. It is artificially emitted when fossil fuels such as coal and oil containing sulfur are burned, and the main emission sources are power plants, heating systems, metal smelting plants, oil refineries, and other industrial processes.

The air pollutants may be classified into gaseous substances such as sulfur dioxide or carbon monoxide and particulate substances such as dust, depending on the particle size. In addition, depending on the production process, it is also divided into primary pollutants and secondary pollutants.

Primary pollutants refer to substances released from sources that have become pollutants as they are. For example, exhaust fumes generated by combustion of coal or oil, dust from cement factories, etc., and sulfur oxides emitted through automobile exhaust pipes, etc.

Secondary pollutants refer to substances that are completely different from primary pollutants by physical and chemical reactions in the air. An example is an oxidizing agent produced by a photochemical reaction of hydrocarbons and nitrogen compounds discharged from automobiles or factories by ultraviolet rays of the sun.

On the other hand, ozone is a substance produced by a photochemical reaction between NOx and volatile organic compounds discharged into the air and ultraviolet rays, and belongs to secondary pollutants. Volatile organic compounds, which are precursors, are generated from various sources, such as industrial facilities such as automobiles, chemical plants, and oil refineries, and natural factors.

Currently, 61 species, including carbon monoxide, ammonia, nitrogen oxides, and sulfur oxides, are designated as air pollutants. Among air pollutants, substances that may directly or indirectly harm human health, property, or the growth of animals and plants are designated as specific air pollutants. Currently, 35 species, including dioxin, benzene, carbon tetrachloride, and formaldehyde, are designated as specific air pollutants.

In addition, yellow dust, wind dust, pollen, bacteria in the air, forest fires, and volcanic eruptions are also the main causes of air pollution and threaten human health. Beijing, China, and Sumatra, Indonesia, are blinded for more than 30 days a year due to artificial forest fires for palm oil production and excessive consumption of fossil fuels. It is impossible to walk the streets without wearing a mask.

In addition, air pollution in construction sites, cleaning sites, specific product manufacturing factories, painting factories, and hospitals is a more serious situation. To avoid this polluted air, people wear face masks during industrial sites or sports activities. In addition, fires in buildings or facilities caused by negligence or earthquakes, fires in cars or trains in tunnels, and toxic gases generated in agriculture or production sites can immediately take away human lives.

Recently, various attempts have been made to protect human respiratory health in such an environment, and one of them is the development of a mask. Since the nose and mouth are the main respiratory systems of humans, it is necessary to protect the nose and mouth with a mask to prevent direct inhalation of air pollutants.

In the development of such a mask, the most important thing to focus on is airtightness. In other words, the goal should be to improve technology that prevents external harmful substances such as fine dust and harmful gases from entering the inside of the mask.

However, a mask with improved airtightness may interfere with the wearer's breathing. If you try on a mask that is on the market, you can see that it is more difficult to breathe than you think. In particular, in the case of a mask made of cotton, it becomes more difficult to breathe when it is in close contact with the nose or mouth due to moisture from breathing.

Therefore, there is a demand for a mask that can smoothly induce breathing of the wearer while improving airtightness.
