The check valve 10 comprises a sealing platform 15 and a sealing gasket 11, wherein the sealing platform 15 is arranged on the check valve 10, and the sealing gasket 11 is detachably arranged on the check valve 10 through a mounting hole 16 arranged in the center of the check valve 10.

The sealing land 15 and the sealing gasket 11 are arranged on the same side of the non-return valve 10.

The exhaust mechanism comprises a sealing sheet 19 and a fixing frame 20; the fixing frame 20 is fixedly arranged on the inner wall of the air outlet hole 18, an assembling groove 21 is arranged on the fixing frame 20, and one end of the sealing sheet 19 is arranged in the assembling groove 21.

The opening of the gas-collecting hood 17 is opposite to the nostril.

The end of the pressure relief buckle 7 provided with the plug 12 and the end far away from the plug 12 form an obtuse angle at the side far away from the shell 1.

The seal piece 19 and the seal 11 are made of soft materials.

A vent channel 22 is provided between the housing 1 and the interlayer 2.

When in use, the shell 1 is covered on the nose of a patient, and the sealing ring 5 is ensured to be attached to the skin around the nose of the patient. The sealing cover 9 on the air suction hole 8 is opened, and air between the shell 1 and the interlayer 2 is pumped out by using air pumping equipment, so that the air pressure of the cavity between the shell 1 and the interlayer 2 is reduced. The one-way valve 10 is arranged in the air suction hole 8, and after the air suction device is taken down after the air suction operation is finished, the sealing gasket 11 on the one-way valve 10 is compressed under the action of atmospheric pressure, so that gas can be prevented from entering again in a short time, and a negative pressure environment between the shell 1 and the interlayer 2 is maintained.

The gas supply tube 23 is supplied with gas to start the supply of oxygen to the patient. In the process of using the oxygen mask, oxygen passes through the oxygen mask 3 and is uniformly discharged through the air holes 4 on the oxygen mask 3, so that the discomfort caused by local long-time air blowing is avoided. The comfort is ensured on the one hand by uniformly discharging oxygen from the oxygen mask 3, and the temperature is reduced for the nose on the other hand. When the patient exhales, the gas-collecting hood 17 facing the nostril prevents the hot air exhaled by the nose from diffusing in the shell 1, and further prevents the hot air from condensing into water vapor in the shell 1. The exhaled gas enters the air outlet 18 through the gas collecting hood 17, one end of the sealing sheet 19 on the fixing frame 20 is pushed open under the action of air pressure and is discharged into the air, the pressure intensity in the air is greater than that in the shell 1 during air suction, and the sealing sheet 19 is pressed tightly to ensure that external gas does not enter.

After the use, the pressure relief buckle 7 is pressed down to separate the plug 12 from the shell 1, so that the external air enters the cavity between the shell 1 and the interlayer 2 and can be taken down.
