Description

Reusable antibacterial mask for fine dust

The present invention relates to a fine dust mask, and more particularly, to a fine dust antibacterial mask.

As the generation of fine dust increases, high-performance filter masks that can filter fine dust are being sold. These fine dust masks filter dust in such a way that small pores that are difficult to pass through filter fine dust and allow air to pass through.

The fine dust mask has enhanced facial adhesion to prevent fine dust from entering the gap between the face and the mask.

In order to increase the facial adhesion of the mask, a thin metal piece deformed according to facial curves is attached to the bridge of the nose, and a method of pulling and fixing it by using a band with strong elasticity is used.

However, these methods increase the filtering effect, but may cause breathing difficulties. In particular, a mask having very small pores in order to filter ultra-fine dust causes a problem in that carbon dioxide emitted through the user's respiration is not discharged through the mask, but causes a problem of re-breathing. For this reason, some experts argue that wearing a fine dust mask is more dangerous.

In addition, fine dust masks cause environmental problems. Since most of the pores of the fine dust mask are clogged with fine dust after use, it cannot be reused and is discarded after single use.

On the other hand, the fine dust mask is made of a thin non-woven fabric with an emphasis on the filtering function, and unlike a general mask made of cloth, it has poor cold protection, and there are problems in that the mask remains on the face due to the mask wearing line pulled to adhere to the face after wearing. Because the aesthetics is low, there is no fine dust, but there is a problem that it is difficult to use on a day when a mask is required, for example, on a day with a lot of yellow dust or pollen, or on a cold day.

The problem to be solved by the present invention is to provide a new mask that can be reused while having a fine dust filtering function.

Another problem to be solved by the present invention is to provide a new mask having a fine dust filtering function, reusable and excellent in design.

Another problem to be solved by the present invention is to provide a new mask that can be used as a general mask when the fine dust concentration is low and can be used as a fine dust mask when the fine dust concentration is high.

Another problem to be solved by the present invention is to provide an antibacterial mask that provides a new mask that can be used as a general mask when the fine dust concentration is low and can be used as a fine dust mask when the fine dust concentration is high.

In order to solve the above problems, the present invention
