Two air bags 7 are installed at the top and bottom of fixing ring 6 respectively, and their materials are also medical grade silica gel, to ensure the close fit and sealing effect with the patient's face. In addition, one side of the two air bags 7 is provided with a gas charging and discharging port 8, through which a special gas charging and discharging tool can be used to inflate or deflate the air bag 7, to adapt to the facial contours of different users, further improve the comfort and sealing performance of wearing. The gas charging and discharging port 8 can be closed by a sealing plug when not in use, to prevent gas leakage.

[0037] In order to realize the quick installation and removal of buffer pad 4, a set of snap-fit assembly is designed in this embodiment. The bottom of face shield main body 1 is fixedly installed with a plurality of L-shaped elastic plates 5, which are all in a curved state, with one end curved towards the outside of face shield main body 1 to form a buckle structure. The side of fixing ring 6 facing the inside is provided with a mounting groove 12, when buffer pad 4 approaches face shield main body 1, one end of the plurality of L-shaped elastic plates 5 automatically enters the mounting groove 12 to realize preliminary fixation. In order to further enhance the fixing effect, the movable end of L-shaped elastic plate 5 is further fixed with a protruding strip 14, and the top inner wall of mounting groove 12 is correspondingly provided with a limiting groove 13, after the protruding strip 14 and the limiting groove 13 are engaged, the connection between fixing ring 6 and face shield main body 1 is more stable.

[0038] Further, the air bag 7 located above is in close contact with the outer wall of face shield main body 1, for sealing the gap between the plurality of L-shaped elastic plates 5, to ensure that the sealing performance of face shield main body 1 is good after wearing.

[0039] The present application can be used in the field of breathing machine, and can also be used in other fields applicable to the present application.
