Problems solved by technology

[0015] On the other hand, in the case of the said patent document 2, since the outside air is sucked in only from both sides of the face cover, there are differences in the number of suction ports and Smaller area reduces the problem of suction flow
[0016] Also in this case, there is also the inconvenience that the filter needs to be replaced by completely separating the face cover and the wearing part when the filter is replaced when the mask is used for a long time
That is, there is a problem that it is difficult to replace the filter while wearing the mask

Description

technical field [0001] The present invention relates to mask devices. Background technique [0002] Generally speaking, a mask is a device that covers the user's nose and mouth in order to avoid the inhalation of germs, dust, etc., or the spread of droplets caused by viruses or bacteria. The mask fits closely to the user's face in order to cover the user's nose and mouth. The mask filters germs, dust, and the like contained in the air flowing into the user's nose and mouth, and allows the filtered air to flow into the user's mouth and nose. Air and germs, dust, etc. contained in the air pass through the body of the mask including the filter, and germs, dust, etc. are filtered by the body of the mask. [0003] But because the air flows into the user's nose and mouth after passing through the body of the mask, the air that the user spits out also flows out after passing through the body of the mask, thereby causing the problem that the user cannot breathe smoothly. Recently...
