Description

Filter replacement mask {MASK OF FILTER REPLACEMENT TYPE}

The present invention relates to a filter-replaceable mask, and more particularly, to a filter-replaceable mask that secures stable wearability and excellent shielding properties through a specific seaming method while being formed of fabric without a separate structural member.

The atmosphere in which people live contains a lot of foreign substances such as fine dust and yellow dust, and these fine dust and yellow dust enter the human respiratory system and cause various diseases, causing fatal adverse effects on people living in modern times. In particular, fine dust and yellow dust are fine and small dust particles that are invisible to our eyes, and may contain numerous air pollutants along with sulfur dioxide, lead nitrogen oxide, ozone, carbon monoxide, and the like.

In addition, recently, it is known that the corona virus is spread due to human-to-human droplet contact.

When these micromerges, etc., penetrate into the human body, various respiratory diseases, headaches, atopy, etc. are induced, and furthermore, there is a problem leading to death.

Accordingly, it is an international trend to recommend wearing a mask when going out.

In this regard, a mask having a filter function to effectively filter fine dust and the like has been provided, but such a filter-integrated mask has a problem in that it cannot be properly adhered to the curved shape of a person's face.

Furthermore, an effective filter replaceable mask has been proposed by securing an accommodating space inside the mask body so that the filter is accommodated in the mask in a replaceable manner, and inserting/removing the filter into the accommodating space through the opening.

However, the conventional filter-replaceable mask has a low adhesion to the user's face, so the blocking rate against fine dust from the external environment is low, and there is a limit that the user cannot easily replace the filter depending on the degree of exposure to harmful substances, and is made of fabric. Accordingly, there was a problem that the shape maintenance was not stable.
