[0029] The second connecting pipe 3 is provided with a second vent 31. The interior of the second connecting pipe 3 is connected to the outside through the second vent 31. The second vent 31 is covered with a third one-way valve 32. The third one-way valve 32 blocks the second vent 31. The air in the second connecting pipe 3 can only be discharged to the outside through the third one-way valve 32. The outside air cannot enter the second connecting pipe 3 through the third one-way valve 32.

[0030] Furthermore, a fourth one-way valve 33 covers the connection between the second connecting pipe 3 and the mask 1; a second connecting ring 34 is connected to the second connecting pipe 3, and one end of the second connecting ring 34 is connected to the second connecting pipe 3.
