As shown in fig. 1, 2 and 3, an embodiment of the present application provides a gas mask with a vision correction device, including: a mask 1 including a mask body 11 for covering a face and a filter device 12 attached to the mask body 11; the guide rail 2 is arranged on the inner side of the cover body 11, and one end of the guide rail 2 is hinged with the cover body 11 so that the guide rail 2 is close to or far away from the inner wall of the cover body 11; the lens bracket 3 is arranged in a transparent area corresponding to the cover body 11 at the inner side of the cover body 11 and can slide up and down along the guide rail 2; a lens mounting frame 4 horizontally sliding along the frame 3; or, the pair of lens mounting frames 4 horizontally symmetrically slide relative to the center of the frame 3; wherein, each lens mounting frame 4 can be detachably connected with at least one lens 5.

Taking fig. 1 as an example, optionally, the whole cover 11 is made of a hard transparent material. The filter unit 12 is installed on the mask body 11, and the filter unit 12 is filled with an air filtering medium, one end of which is located outside the mask body 11 for interaction with air in the external environment, and the other end of which is located inside the mask body 11 for covering the nose and mouth of a user.

The lens holder 3 is provided inside the cover 11 and above the filter device 12. In order to enable the frame 3 in the respirator of the present embodiment to maintain an appropriate distance from the face of the user due to the difference in the projected height of the facial bones of each person, a guide rail 2 is provided on the inner side of the hood 11.

As shown in fig. 2, 3 and 4, a protrusion 7 having a hinge axis is fixedly provided on the inner wall of the cover 11, and the hinge axis is horizontally provided. The upper end of the guide rail 2 is connected with the hinge shaft so that the guide rail 2 is integrally rotated about the hinge shaft, as shown in fig. 3 and 4. Along with the rotation of the guide rail 2, the lens frame 3 on the guide rail 2 can be adjusted in a swinging mode between the face of a user and the inner wall of the cover body 11, namely, the distance between the lens frame 3 and the face of the user is adjusted.

In order to allow the frame 3 in the respirator of the present embodiment to correspond to the eyes of the user due to the difference in distance between the eyes and the nose of each person, the frame 3 can slide up and down along the guide rails 2, as shown in fig. 3 and 4.

Because everyone's interpupillary distance is different, in order to make lens 5 in the respirator of this embodiment can correspond to user's eyes, set up slidable lens installing frame 4 on mirror holder 3 to make lens 5 can be along with lens installing frame 4 horizontal slip, realize that lens 5 position can adjust according to user's eyes position.

The respirator with the vision correction device provided by the embodiment has the advantages that the effect of supporting the spectacle frame 3 is realized along the vertical guide rail 2 on the inner side of the cover body 11, and the mutual extrusion between the spectacle legs horizontally arranged and the inner wall of the cover body 11 is avoided. On one hand, the outer contour of the mask body 11 can be reliably attached to the face of a user, and the air tightness of the gas mask of the embodiment is ensured; on the other hand, set up mirror holder 3 in the cover body 11 inboard to adjust the distance between mirror holder 3 and the user face through rotatable guide rail 2, when guaranteeing to correct user's eyesight, improve the travelling comfort of wearing. Meanwhile, the positions of the lenses 5 can be adjusted according to the positions of the eyes of the user through the lens frame 3 capable of sliding up and down and the lens mounting frame 4 capable of sliding along the lens frame 3, so that the gas mask has strong universality.

In order to limit the rotation of the guide rail 2, a protruding arc-shaped guide rod 6 is provided on the inner wall of the cover 11. As can be seen from the foregoing, when the guide rail 2 is adjusted, the guide rail 2 rotates around the hinge shaft, the moving track of the lower portion thereof is an arc line, and the center of the arc line is located at the hinge shaft. The axis of the arc-shaped guide rod 6 is superposed with the moving track of the lower part of the guide rail 2.

Optionally, a through hole or a groove may be provided on the guide rail 2, and the arc-shaped guide rod 6 passes through the through hole or the outer circumferential wall thereof abuts against the groove to realize sliding fit between the guide rail 2 and the arc-shaped guide rod 6. In the same way, a through hole or a groove can be formed in the arc-shaped guide rod 6, and the end part of the guide rail 2 penetrating through the through hole or the guide rail 2 is abutted against the inner wall of the groove, so that the same effect can be achieved.

As shown in fig. 3 and 4, in some embodiments, the lower portion of the guide rail 2 is provided with a guide through hole 21 for inserting and matching with the arc-shaped guide rod 6; the first damper 22 is attached to the guide through hole 21, and the first damper 22 abuts against the outer peripheral wall of the arc-shaped guide bar 6.
