The lens hole 101 is used for accommodating a lens, and the lens hole 101 includes but is not limited to a circular hole, an elliptical hole, a triangular hole, a square hole or a polygonal hole, in this embodiment, the lens hole 101 is a circular hole, and the corresponding lens installed in the lens hole 101 is a circular lens. In the present embodiment, the fixing and supporting portion 102 is disposed on the beam portion 13. As shown in fig. 4, an arc-shaped gap 103 is preferably formed between the left frame 11, the beam portion 13 and the right frame 12, and the arc-shaped gap 103 is opposite to the nose pad portion 22. Two side surfaces of the arc notch 103 are respectively a part of the outer surfaces of the left frame 11 and the right frame 12, and the bottom surface of the arc notch 103 is a part of the outer surface of the beam portion 13. The arc-shaped notch 103 corresponds to the nose pad part 22 of the face-attaching elastic sheet 20, so that the circumferential profiles of the support 10 of the mask and the face-attaching elastic sheet 20 are the same or similar, and the overall aesthetic property of the mask is improved. In addition, the beam portion 13 is provided with a mounting hole 104, and the mounting hole 104 can be used for mounting some components, for example, the mounting hole 104 is used for mounting a sensor on a display device in this embodiment.

The middle part of the face-attaching elastic sheet 20 is sunken towards the support 10, that is, along the direction from the left frame body 11 to the right frame body 12 of the support 10, the contour shape of the face-attaching elastic sheet 20 is approximately arc-shaped, the contour shape of the face-attaching elastic sheet 20 is similar to the contour of the face of a user, and the face-attaching elastic sheet 20 can be attached to the face of the user when the user wears the mask. The face-attaching elastic sheet 20 is made of an elastic material, so that the face-attaching elastic sheet 20 can deform under the action of external force, the face-attaching elastic sheet 20 can be attached to different faces, and the applicability of the mask is improved.

This embodiment the face-attached elastic sheet 20 is cyclic annular elastic sheet, and the shape of cyclic annular elastic sheet is similar to the racetrack shape, specifically, and it is including relative left side and the right side that sets up to and relative last side and the lower side that sets up, wherein, go up the side and be located between left side and the right side, and be connected with left side and right side respectively, left side, right side, go up side and lower side structure as an organic whole, left side, right side, go up side and lower side enclose into eyepiece hole 21. The upper side and the lower side of the annular elastic sheet are both arc-shaped, and the middle of the lower side of the annular elastic sheet is sunken upwards to form a nose pad part 22. Eyepiece hole 21 is including being located the left eyepiece hole portion and the right eyepiece hole portion of nose pad portion 22 both sides, the one side intercommunication that left eyepiece hole portion and right eyepiece hole portion are relative each other. With this arrangement, the visual field range of the eyepiece hole 21 can be enlarged. The left eyepiece hole portion corresponds to the left lens hole of the left frame 11, and the right eyepiece hole portion corresponds to the right lens hole of the right frame 12.

The elastic support strip 30 is a strip-shaped elastic strip for controlling the deformation of the face-contacting elastic sheet 20.
