[0029] When in use, the second transmission wheel 16 and the third transmission wheel 20 are arranged to cooperate with the first transmission wheel 14 to drive the second transmission belt 15 to operate;

[0030] A second transmission belt 15 is wound around the outer wall between the third transmission wheel 20, the second transmission wheel 16 and the first transmission wheel 14, and an exhaust pipe port 21 is provided at one end of the exhaust fan 19;

[0031] When in use, the second transmission belt 15 is provided to drive the exhaust fan 19 to operate;

[0032] An air bleed pipe opening 22 is provided on the outer wall of one side of the exhaust fan 19, and a filter screen 23 is installed inside the air bleed pipe opening 22;

[0035] When the embodiment of the present application is in use, the driving wheel 5 is first driven to rotate by the rotating driving member 3 via the rotating shaft 4, so that the driving wheel 5 drives the driven wheel 7 to rotate via the first transmission belt 6, so that the driven wheel 7 drives the blade member 24 to rotate via the linkage shaft 13, and the vacuum pump body 10 can be driven to operate by belt transmission, so that the vacuum pump is relatively stable during operation.
