The specific embodiment

Like Fig. 3, shown in Figure 4, this utility model is a kind of novel respirator, and it mainly is made up of the medical check valve of the medical check valve of face shield loam cake 1, face shield air cushion 2, first 3, second 4, little valve block 5, big valve block 6 and breather valve 7.

Described face shield loam cake 1 snaps onto on the face shield air cushion 2, wears 3, the second medical check valves 4 of the first medical check valve at the sidewall of face shield air cushion 2 and is nested with the upper surface at face shield loam cake 1.

Offer two

ventilation pores

11,12 that diameter is different on described face shield loam cake 1 upper surface, two

ventilation pores

11,12 of described face shield loam cake are counterbore 11,12.Central authorities in counterbore 11 bottoms that are connected with breathing pipeline (not shown) offer an aperture 111, and these counterbore 11 diameters are less.Be nested with breather valve 7 counterbores 12 centres at another and offer an aperture 121 and offer three scallop holes 122 around this aperture 121, these counterbore 12 diameters are bigger.
