The purpose of this utility model realizes with following mode:
The utility model is made of passage 1, face shield 8 and support 2, and wherein: support 2 surrounds annular, has a gas-flow closure circle 4 on the support 2, and gas-flow closure circle 4 is an annular, has valve 3 above.Valve 3 is a pipe, in pad 6 and nail 7 are housed, nail 7 passes pad 6.Have hook 5 on the face shield 8.
The utility model compared with prior art has following advantage:
Because sealing ring adopts inflatable structure, comfortable during feasible wearing, match with shape of face, sealing effectiveness improves greatly, and simultaneously, the mouth mask skeleton reduces greatly to the active force of face.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model
Fig. 2 is a side view of the present utility model
Fig. 3 is the utility model air valve structure figure
Among Fig. 1: 1, passage; 2, support; 3, valve; 4, the gas-flow closure circle
Among Fig. 2: 5, hook; 8, face shield.
Among Fig. 3: 6, pad; 7, nail.
In Fig. 2, have a circle ring support 2 on the face shield 8, be fixed with the gas-flow closure circle along support, hook can be arranged symmetrically in two outsides of face shield 8.
Below in conjunction with embodiment the utility model is elaborated:
Fig. 1 to 3 can be used as an embodiment of the present utility model:
Be threaded on the passage 1, can tap into escape pipe, face shield 8 is made by transparent plastic, support 2 adopts polyethylene from high pressure process, and gas-flow closure circle 4 is the polyethylene from high pressure process light-wall pipe, is connected with support 2 heat seals, earlier from valve 3 inflation in pipe, make two packing ring 6 reducings, sealed air valve 3 before using by nail 7.After during use elastic webbing being buckled in brain by two hooks, support will the oral cavity together with the gas-flow closure circle and nose around sealing.
The gas-flow closure circle can also be made of other elastomeric material, and face shield can use the face shield of other form, and it is same as the previously described embodiments to seal close effect.
