AI Technical Summary
Myopic people cannot clearly see the environment when wearing respirators, which leads to difficulties in their work.
A myopia lens mounting assembly for a breathing mask is designed, including transparent lenses, fixed suction cups and fixing frames. The myopia lenses are fixed on the transparent lenses through fixed suction cups. The fixing frame is applied to the user's eye socket surface by elastic material to achieve stable fixation of the lenses.
It is realized that myopic people can clearly see the environment when wearing a breathing mask, avoid lens displacement, and improve the user's operation convenience.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of respirators, in particular to a myopic lens mounting assembly for a breathing mask. Background Technique
[0002] A self - contained breathing apparatus is a device used to provide the normal required air in special environments; it is mainly applied to areas such as fires, gas leaks, volatile liquid leaks, and confined spaces where harmful gases are generated or the oxygen content is low; all the woven materials of its shoulder straps and waist belts are made of fire - resistant and flame - retardant materials, and all metal connectors are made of stainless steel, eliminating potential safety hazards for operators.
[0003] The existing breathing apparatus protects the face in the form of a mask. However, due to the reduced internal space of the breathing apparatus, myopic people cannot wear their glasses, resulting in myopic people being unable to see the environment clearly and having difficulty in operating. Therefore, a myopic lens mounting assembly for a breathing mask is proposed to solve the above problems. Summary of the Utility Model
[0004] The utility model provides a myopic lens mounting assembly for a breathing mask, which solves the above - mentioned technical problems.
[0005] To solve the above - mentioned technical problems, a myopic lens mounting assembly for a breathing mask provided by the utility model includes a breathing hood, a mask is fixed on the surface of the breathing hood, a transparent lens is fixed inside the mask, a fixing suction cup is connected to the surface of the transparent lens, a fixing frame is fixed on the surface of the fixing suction cup, a myopic lens is fixed inside the fixing frame, and an air inlet pipe is fixed on the surface of the breathing hood.
[0006] Preferably, a filter box and an exhaust valve are arranged on the surface of the breathing hood, and a sealing rubber is fixed on the surface of the mask.
[0007] Preferably, straps are fixed on the surfaces of the breathing hood and the sealing rubber, and a backpack buckle is connected to the surface of the straps.
[0008] Preferably, both the fixing frame and the myopic lens are arc - shaped, and the radian of the fixing frame and the myopic lens is equal to the radian of the surface of the transparent lens.
[0009] Compared with the related technology, a myopic lens mounting assembly for a breathing mask provided by the utility model has the following beneficial effects:
[0010] The utility model fixes the myopic lens on the transparent lens through a fixing suction cup, and can replace lenses with different degrees according to the needs of users. The fixing frame is made of elastic material and can be attached to the surface of the user's eye socket, avoiding displacement during the user's operation and facilitating the user's operation.
