Masks are especially important during outbreaks of infectious diseases such as the flu. But the general public is less aware of masks. This is a mask designed for the public. It can remind the change time by changing the emoticon of the mask. When the color of the emoticon disappears, it indicates that the mask has been used, so as to prevent the second use. The direction of the smiley faces on the emoticon bars can also tell people how to wear them, and the facial expression on the mask can also convey positive energy.
