detailed description

The present invention will be further described below in conjunction with the accompanying drawings:

As shown in the figure, the air bag type breathing apparatus is mainly composed of a breath filter air bag 1, an air bag holder 2, a mouthpiece 3, and a nose pad 4.

The respiratory filter airbag 1 is composed of a surface layer nonwoven fabric 12 and an inner layer nonwoven fabric 11, and the periphery of the surface layer nonwoven fabric 12 and the inner layer nonwoven fabric 11 are sealed together, and the surface layer nonwoven fabric 12 and the inner layer nonwoven fabric are laminated. An air bag (cavity) is formed between the 11 layers, and the inner layer nonwoven fabric 11 is provided with a nasal breathing hole 13 (two) and a mouth breathing hole 14 communicating with the inner cavity air bag, and the inner layer non-woven fabric 11 is further provided with The insertion plate 15 of the airbag holder 2 is connected, and the insertion plate 15 is provided with a insertion groove 16, and the surface nonwoven fabric 12 may have a hole (not shown) for connecting the airbag holder 2.

The shape and size of the airbag bracket 2 (plastic material or metal material) is adapted to the respiratory filter airbag 1, the two ends of which are the lifting lugs 22, the middle of which is the insertion frame 21, and the airbag bracket 2 is respectively connected with the nose and the mouth The nose pads 4 and the mouthpieces 3 are attached, and the nose pads 4 are attached to the lifting ears 22 of the bracket 2 through the hanging arms 43 on both sides, and the mouthpieces 3 are softly connected to the hangers of the brackets 2 through the rubber strips 33 on both sides.
