It should be noted that the sealing ring 141 can be made of rubber or silicone. A stopper 231 is connected to the upper end of the screw rod 230, and a limiting ring 250 is connected to the surface of the rotating rod 221. In a specific implementation, a stopper 231 is connected to the upper end of the screw rod 230, and a limiting ring 250 is connected to the surface of the rotating rod 221, thereby reducing the possibility that the connecting sleeve 241 will fall off the screw rod 230, and at the same time reducing the possibility that the stopper 231 will collide with the protective shell 140.

[0031] A connecting sleeve 241 is connected to the surface of the scraper 240, and the connecting sleeve 241 is threadedly sleeved on the surface of the screw rod 230. In specific implementation, by starting the motor 210, its output shaft drives the first bevel gear 211 to rotate, and the first bevel gear 211 drives the second bevel gear 222 to rotate, and then drives the rotating rod 221 and the screw rod 230 to rotate, so that the connecting sleeve 241 can rotate and move up and down, thereby driving the scraper 240 to rotate and move up and down along the inner wall of the suction tube 130, reducing the possibility of sputum adhering to the inner wall of the suction tube 130 of the suction device body 100, causing the suction tube 130 to be blocked.
