The staff can slide the mounting plate 9 to make the mounting block 13 slide out along the mounting groove 12, so that the rigid connecting pipe 8 is separated from the connection box connector 19. Then the mounting plate 9 and the mounting block 13 can be taken out, and the connecting hose 10 connected to the rigid connecting pipe 8 can be taken out, which is convenient for personnel to use. Even if the connecting hose 10 is damaged, the staff can also maintain it more conveniently, which is convenient for personnel to use.

[0042] Working principle: In actual use, the rotating mechanism 14 rotates along the threaded hole opened on the connecting plate 17, so that the push plate 15 approaches the connecting hose 10. The connecting hose 10 is squeezed by the rubber pad 16 to deform the connecting hose 10. By compressing the connecting hose 10 to the extreme so that the connecting hose 10 cannot supply oxygen, the remaining connecting hoses 10 supply oxygen into the connection box body 18. Oxygen is supplied into the humidifying tank 2 through the air pipe 4 and finally into the breathing mask through the oxygen supply pipe 3. By changing the number of connecting hoses 10 for supplying oxygen as described above, the oxygen supply pressure of the device is affected and changed, so that the device can adapt to the oxygen supply work for different people, improving the adaptability of the device. Moreover, the mounting plate 9 with the rigid connecting pipe 8 and the connecting hose 10 can be disassembled and replaced, which is convenient for personnel to maintain later.
