[0017] S3: The synchronous wheel 1 is driven to rotate by the motor 2, and the fan head is driven to rotate to blow air into the air guide shell. The air guide shell sends the air flow into the collection chamber, and blows the flying dust to the water surface.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The docking tube is installed and used together with the existing medical ventilation tube. During the use of the ventilation tube, the internal air will be filtered through the filter. After a period of use, the surface of the filter will be sticky with a lot of dust. Two sets of motors are used to drive two sets of threaded rods to rotate, so that the two sets of threaded sleeves connected by thread drive the movable frame to move horizontally, and the other set of filters replaces the filters corresponding to the docking tube. The filters saturated with dust are moved to the position of the corresponding round shell in the square shell. At this time, several sets of knocking rods 1 and knocking rods 2 are driven by motor 2 to process the filters. The corresponding plug plates can also be pulled out to open the square shell, and the threaded filters can be removed from the movable frame for convenient replacement and other processing at a later time.

When the cam one rotates, it pushes the meshing cam two to make the movable shell slide along the sliding bar, and at the same time drives several groups of springs to stretch. The push of the cam one and the elastic stretching of the spring make the movable shell drive several groups of knocking rods one and two to reciprocate back and forth. Several groups of knocking rods one and two knock on the filter to make the dust on the surface fall off, which is convenient for the next work.

[0021] The knocked dust will fall into the water at the bottom of the collecting chamber and will not affect the air in the ventilation pipe and the docking pipe. When the gear 1 and the sliding rod are driven by the rack and the half gear to rotate reciprocatingly, the driven turntable drives several groups of knocking rods 1 and 2 through the driving port to open outward at the same time and move together after opening, so that several groups of knocking rods 1 and 2 can evenly knock on the surface of the filter, the vibration produced is more uniform, and the cleaning effect is better.

[0022] The rotation of synchronous wheel one drives the sleeved synchronous belt two, which drives a group of connected synchronous wheels two. The synchronous wheels two respectively drive other three groups of synchronous wheels two to rotate through the three connected groups of synchronous belts one, so that the fixed fan shaft and fan head rotate, and air is blown into the air guide shell. The air guide shell sends the airflow into the collection chamber, blows the flying dust generated by the vibration to the water surface and sticks it, thereby improving the working environment inside the collection chamber.
