Detailed description of the invention

Consult Fig. 1, Fig. 2, Fig. 3, the utility model comprises main cavity 1, exhaust cavity 2, Connection Block 3, breathing catheter 4, MULTILAYER COMPOSITE filter screen 5, added filter 6, backing plate 7, exterior trim towel 8, frenulum 9, face seal 10 and mouth breathing filter disc 11, the rectangular housing of described main cavity 1 several air inlet for front is provided with, its end face is provided with two breathing catheter interfaces 11 and backing plate seat 14, two sides are provided with discharge chamber interface 12, and air inlet is provided with air suction valve 13, exhaust cavity 2 is for being provided with the rectangular housing of kettle mouth 21, one side is provided with connector, another side is provided with valve base, and valve base is provided with exhaust valve 22, the top of backing plate 7 is provided with pneumostome,

Described main cavity 1 is placed in middle part, exhaust cavity 2 is symmetrically placed in both sides and is connected with Connection Block 3, the discharge chamber interface 12 of main cavity 1 is connected with the connector of exhaust cavity 2, breathing catheter 4 is located on the breathing catheter interface 11 of main cavity 1, MULTILAYER COMPOSITE filter screen 5 and added filter 6 are located at the outside of main cavity 1 frontal inlet mouth successively, backing plate 7 is located at main cavity 1 back side and is connected with backing plate seat 14, face seal 10 is arranged on the periphery of backing plate 7, mouth breathing filter disc 11 is located on the pneumostome of backing plate 7, exterior trim towel 8 is wrapped in the outermost of MULTILAYER COMPOSITE filter screen 5 and added filter 6, frenulum 9 is located on exhaust cavity 2 and Connection Block 3.

The utility model uses like this:

Consult Fig. 1, Fig. 2, Fig. 3, of the present utility modelly to wear, symmetrically arranged breathing catheter 4 is filled in two nostrils, face seal 10 is attached between the bridge of the nose, lower jaw and both sides cheek, frenulum 9 is wrapped in the back side of head and fastens, make the face of the utility model and people and nasal cavity relative fixing.

The utility model is work like this, when nostril air-breathing, forms negative-pressure gas in main cavity 1, and under the effect of negative pressure, the diaphragm on exhaust valve 22 is adsorbed on the kettle mouth 21 of exhaust cavity 2, is automatically closed by exhaust valve 22; On main cavity 1 air inlet, the diaphragm of air suction valve 13 is opened by negative-pressure gas, and fresh air is entered by main cavity 1 frontal inlet mouth through MULTILAYER COMPOSITE filter screen 5 and added filter 6, then enters nasal cavity by breathing catheter 4 and complete breathing process;
