One side of the outer wall of the dust cup cover 7 is provided with a connecting post 9. Correspondingly, a connecting seat 10 is provided on the outer wall of the dust cup 8. The dust cup cover 7 is rotatably fixed on the dust cup 8 by a shaft pin. An anti-backflow cover 11 is provided inside the dust cup cover 7 to prevent the air inhaled from the dust cup cover 7 from flowing back. A filter screen cylinder 12 is fixed at the center of the dust cup 8. The filter screen cylinder 12 filters objects such as dust and garbage to prevent the garbage from entering the air inlet pipe 2 and damaging the air pump main body 1. The locking mechanism 13 includes a locking groove 14 provided on the outer wall of the dust cup cover 7. A fixing seat 15 is provided on the outer wall of the dust cup 8. A rotatable fixing buckle 16 is provided on the fixing seat 15 to match the fixing buckle 16 with the locking groove 14 to achieve snap connection and fixation. A spring is provided between the fixing buckle 16 and the fixing seat 15 on the other side to keep the fixing buckle 16 in a tendency to lock the locking groove 14. In this way, by unlocking the fixing buckle 16, it is convenient to clean the garbage in the dust cup 8.

[0023] An L-shaped card slot 17 is provided on the outer wall of the bottom of the dust cup 8. The adapter 18 also serves as the bottom of the dust cup with an outlet. Correspondingly, a clamping block 19 is provided on the inner wall of the adapter 18 to achieve screwing-in fixation. The dust cup 8 can be quickly screwed off or screwed onto the adapter 18. A thread 20 is provided at the bottom of the adapter 18 to match the thread groove 13 of the air inlet pipe 2 to achieve screwing-in fixation.
