This design is to solve the problem that the mask is sold twice and infected twice, and people can't accurately identify whether the mask has been used. This design is based on the behavior that people will pull the belt apart when using it. When people use masks to open the outer ear belt, the set ant line area will be opened. In this way, when people see it again, they will know that the mask has been used to prevent it from being recycled for sale. In this way, people will know which mask they have used.
