Abstract:
A mask, comprising a first frame body (100), a light-transmitting piece (200), and a filtering assembly (300); the first frame body (100) is used for covering the face of a user; the first frame body (100) is provided with a first through hole (110) opposite to the lips of the user; the light-transmitting piece (200) covers the edges of the first through hole (110) so as to seal and block the first through hole (110), light rays on the inner side of the first frame body (100) can transmit to the outer side of the first frame body (100) by means of the light-transmitting piece (200), and the light-transmitting piece (200) protrude outwards; the filtering assembly (300) is used for filtering the air inhaled and exhaled. As the light-transmitting piece (200) protrudes outward, the light transmitted through the light-transmitting piece (200) can be dispersed in a fan shape, such that other people can observe the lip movement of the user without having to stand directly in front of the user, thereby improving the communication efficiency between the user and other people.
