Mask device for blocking fine dust {FINE DUST BLOCKING MASK APPARATUS}

The present invention relates to a mask device for blocking micro-merge, and more specifically, an air curtain is formed around the user's respirator to block the inflow of contaminated external air and at the same time, fresh and clean air purified through a filter is transferred to It relates to a mask device for blocking fine dust using an air curtain that supplies and provides comfortable air.

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

The causes of such air pollution are divided into natural ones such as sand storms and volcanic eruptions in deserts and artificial ones such as waste gas from factories and combustion of fuel.

Normally, natural pollutants are caused by natural physiology and are temporarily generated, so they do not pose a lasting big threat to human respiratory health. However, artificial pollutants are discharged from combustion of fuel, generation of nuclear energy using nuclear energy, chemical reactions, physical processes, and automobiles and aircraft. The main cause is various pollutants generated during combustion of fuel, and human respiratory health Has a lasting negative impact on

Among them, 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 produce additional secondary pollutants. Air pollutants can be classified into gaseous substances such as sulfurous acid gas or carbon monoxide, and particulate substances such as dust, depending on the particle size.

In addition, yellow dust, dusty wind, pollen, airborne bacteria, wildfires, volcanic eruptions, etc. are also the main causes of air pollution and threaten human health.

In addition, air pollution in construction sites, cleaning sites, factories for manufacturing specific products, painting factories, and hospitals is a more serious situation.

Particularly, fine dust, which has a great influence on the modern society, is a suspended substance in the atmosphere with various complex components, and refers to particulate matter with a diameter of 10㎛ or less, and is mainly generated when fossil fuels such as coal and petroleum are burned. In particular, it is an air pollutant that is generated in large quantities from exhaust gases such as manufacturing plants or automobiles.

These fine dusts are mainly composed of combustion particles such as carbon, organic hydrocarbons, nitrates, sulfates, and harmful metal components, and are known to be related to the occurrence of respiratory and cardiovascular diseases and to increase mortality.

Accordingly, devices for removing fine dust are being developed, such as'a dust collecting device capable of removing fine dust' in Korean Patent Publication No. 10-1633878, which is a prior art document.

The above-described prior document (No. 10-1633878) is a lower frame, a frame support fixed by a coupling member on the upper part of the lower frame, and the frame support that is coupled to be elevating and descending while supported by a guider inside the frame support. To provide a dust collecting device capable of removing fine dust comprising a filter housing, a filter plate coupled to the filter housing to filter dust, and a vibration generating device installed on the lower frame to apply vibration to the filter housing, A technology capable of removing large-capacity dust has been disclosed by allowing the fine dust adhered to the filter due to prolonged use or a lot of dust to be reliably and quickly removed by vibration that raises and lowers the filter plate.

However, the prior literature has a limitation that modern people with a large amount of activity cannot use while out or on the move as a device having a dust collecting function.

Therefore, in recent years, various attempts have been made to protect the respiratory health of humans in such an environment, and the development of a mask can be mentioned as part of that.

Since the main respiratory system of a person is the nose and mouth, the nose and mouth are protected 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 hermeticity.

In other words, it should aim to improve technology to prevent external harmful substances such as fine dust and harmful gases from entering the mask.

However, the mask having improved sealing property has a problem that interferes with the user's breathing.

Therefore, there is a need to develop a mask that does not interfere with the user's breathing as it is constructed in a structure that does not completely seal the user's respiratory system, and that external harmful substances are blocked and only filtered clean and safe air can be supplied to the user. .
