Can not protect the health of users

However, most of the masks currently on the market have poor adhesion, especially in the nasolabial folds and jaws. It will bring great hidden danger to the safety of users

Since the mask is worn for a long time, there are also high requirements for its wearing comfort, because the user will produce sweat and other liquids in the process of wearing the mask. If it is not treated to a certain extent, it is easy to cause liquid accumulation and affect the use.

[0005] The Chinese invention patent with the authorized notification number CN208987852U discloses a cordless protective mask structure, which discloses that the inner edge of the mask body is bonded with a soft rubber strip to improve the fit between the mask and the human face, but as a medical mask, it needs to resist For allergies, the sweat-absorbing function is also particularly necessary, and it must be comfortable.
