Referring to FIGS. 3, 5 and 6, during this process, since the oxygen supply module 31 will continue to provide oxygen to the oxygen supply pipe 34, and the air supply module 33 will continue to provide air pressure, the user can inhale Oxygen (see the direction of the airflow arrow in Figure 6).

Referring to Figures 3, 5, and 7, when it is determined that the user is in the exhalation state, since the suction pipe 35 will be sucked, the air pressure continuously provided by the air supply module 33 can maintain the user's The airway is unobstructed and does not collapse, so the sputum will be sucked up, and will pass through the perforations 221, the front inner hole 621, the guide hole 533, the rear inner hole 721, the rear outer hole 711 and the After the suction pipe 35 is collected, it is collected in the filters 322 .

Since the whole process is carried out by an automatic procedure, the operation steps of the operator can be greatly reduced, and the technical requirements of the operator can be reduced.

It is worth mentioning that, in other embodiments, the automatic sputum suction device can also cancel the drive unit 5, the front adapter unit 6 and the rear adapter unit 7, and the main oxygen supply pipe 21 and the The main sputum suction pipe 22 is separated and arranged, and the main oxygen supply pipe 21 and the main sputum suction pipe 22 are respectively connected to the oxygen supply connecting pipe 34 and the air suction connecting pipe 35, and the main oxygen supply pipe 21 and the main suction pipe 22 are respectively connected. The sputum tube 22 penetrates into the user's mouth or nostrils, and continuously provides oxygen through the oxygen supply module 31. The control unit 8 automatically determines the user's breathing state and can manually adjust the main sputum suction tube 22. position for sputum suction, since the operator does not need to consider the blood oxygen concentration of the user, the effect of reducing the technical requirements of the operator can also be achieved.

In addition, referring to FIG. 8 , in other embodiments, the positioning sensor 57 can also be a resistance change, optical or magnetic distance sensor, which can achieve the same effect by sensing whether there is an obstacle ahead .
