After the supporting rod 67 downward supports the supporting block 66 to drive the pipe body 611 to rotate upwards through the attraction of the magnetic block 212 and the magnetic ring 613, the pipe body 611 drives the magnetic ring 613 to rotate upwards, so that after the magnetic ring 613 is close to the magnetic block 212 on the outer wall of the mask portion 21, the magnetic block 212 attracts the magnetic ring 613 to fix the pipe body 611 on the inner wall of the mask portion 21, and normal breathing of a user is facilitated. When the user opens his mouth to expectorate, the sliding rod 63 slides up again to drive the abutting block 66 to abut against the abutting rod 67, and the pipe body 611 is driven to rotate downwards, so that the magnetic ring 613 breaks away from the magnetic block 212 to release the adsorption locking of the pipe body 611, and the pipe body 611 can be conveniently rotated downwards and then transferred into the oral cavity of the user.

The implementation principle of the portable auxiliary respirator provided by the embodiment of the application is as follows: when the user expects phlegm by wearing the respiratory mask 2, the user's mouth opens the portion. The chin of the user pushes the driving plate 62 to drive the connecting part 621 to stretch, and then drives the driving gear 64 to rotate. The engagement of the driving gear 64 with the rack 65 drives the sliding rod 63 to slide upwards, and the sliding rod 63 drives the abutting block 66 to slide upwards. The abutting block 66 abuts against the abutting rod 67 to rotate upwards to drive the adapter 612 to rotate, and the adapter 612 drives the pipe 611 to rotate downwards and separates the magnetic ring 613 from the magnetic block 212. After the locking of the tube body 611 is released, the tube body 611 is turned into the oral cavity of the user downwards, and then the liquid pump 68 is started to pump the sputum in the oral cavity of the user into the respirator body 1 through the tube body 611, the adapter 612 and the liquid pump 69.

After the extraction is finished, the rear mouth is opened completely, the connecting part 621 is driven to continue stretching, the sliding rod 63 is driven to continue sliding upwards through the meshing of the driving gear 64 and the rack 65, and the sliding rod 63 drives the abutting block 66 to slide across the abutting rod 67 until the abutting block 66 is positioned above the abutting rod 67. At this time, the user's mouth releases the tube 611 and closes the mouth, the connecting portion 621 pulls the driving plate 62 to reset and abut against the mask portion 21, and drives the sliding rod 63 to slide down through the engagement of the driving gear 64 and the rack 65, so that the abutting block 66 abuts against the abutting rod 67 downward, and further the tube 611 is driven to rotate upward at one end far away from the adapter 612 until the magnetic ring 613 abuts against the magnetic block 212, so that the tube 611 is fixedly adsorbed on the inner wall of the mask portion 21. The whole process realizes the suction and the reset of the suction pipe 61 by the action of the mouth of the user, thereby facilitating the suction of sputum when the patient wears the mask for expectoration.
