Description

Mask {Mask}

The present invention relates to a mask capable of replacing a filter unit.

Recently, with the increase of fine dust generated in Korea and the increase of fossil fuel combustion due to the industrialization of China, the amount of fine dust that flows into the country is increasing, and exposure to fine dust is increasing. Fine dusts contain a large amount of toxic compounds and heavy metals, and when inhaled by humans, they are known to cause diseases such as heart attack, asthma, bronchitis, pneumonia and lung cancer. According to one study, it is reported that 20,000 deaths and lung-related diseases occur annually in the metropolitan area due to fine dust. A mask is used to block the entry of such fine dust into the human body.

In addition, cases are worn in everyday life to prevent infection or transmission from infectious germs that cause Severe Acute Respiratory Syndrome (SARS), the Middle East Respiratory Syndrome (MERS) that recently became popular in Korea, and colds.

These masks typically consist of a body portion covering the wearer's nose and mouth peripheral respiratory and an earring portion providing the wearer with means for fastening the mask. In some masks, the nose covering the nose and the jaw surrounding the jaw may be separated to enhance the comfort of the wearer or the close contact between the mask and the face in order to block the inflow of outside air.

In addition to a general mask, there is also a mask for enhancing adhesion and for increasing the blocking of fine dust introduced from the outside. Such a mask generally includes an electrostatic filter capable of blocking fine dust in the mask body for blocking fine dust. The elasticity of the earring portion is generally applied, and the length of the earring strap is adjusted to provide convenience to the wearer.

The conventional mask is generally made flat and covers the periphery of the respiratory apparatus even when worn, or is configured to be folded in a flat shape, but it can be worn in a three-dimensional form when wearing a mask.

Such a mask is particularly wasted because the mask having a filter function is contaminated even if it is used only once, and the filter is damaged during cleaning, which makes it difficult to reuse, and efforts to improve such a mask have been continuously made.

SUMMARY OF THE INVENTION The present invention has been made to improve the prior art. It is an object of the present invention to provide a mask capable of minimizing a filter part to be replaced and easily manufacturing a frame part for fixing the filter part.
