Example 7

The reciprocating transmission mechanism 6 comprises a T-shaped sliding rail 601, the T-shaped sliding rail 601 is transversely arranged, a sliding block 602 is matched with the T-shaped sliding rail 601, and the sliding block 602 is provided with a transversely penetrating sliding groove matched with the T-shaped sliding rail 601; a sleeve shaft 603 is arranged at the top of the sliding block 602; a connecting rod 604 is inserted in the axis of the sleeve shaft 603; the upper end of the connecting rod 604 is fixedly connected with the movable tube 2; also includes a gear reducer 605; the output shaft of the motor 7 passes through and moves the gear reduction box 605; a rotating shaft 606 is arranged at the power output position of the gear reduction box 605; a rotating disc 607 is arranged at the upper end of the rotating shaft 606; the top of the rotating disc 607 is eccentrically provided with a first sleeve shaft 608; a driving rod 609 is fitted between the sleeve shaft 603 and the first sleeve shaft 608, two ends of the driving rod 609 are provided with collars 610, and bearings are fitted between the collars 610 at the two ends and the sleeve shaft 603 and the first sleeve shaft 608 respectively; the T-shaped slide rail 601 and the gear reduction box 605 are both fixedly arranged at the top of the frame 4.

In the above technical solution, the motor not only drives the negative pressure impeller to rotate, but also drives the gear in the gear reduction box 605 to rotate, and the gear transmission is used for reducing the speed, so that the rotating shaft 606 rotates 1 ring every time the motor rotates N rings, and N = 120.

Through the rotation of the rotating shaft 606, the rotating disc 607 rotates, and due to the eccentric installation of the first sleeve shaft 608, the driving rod 609 pulls the sliding block 602 to make a transverse reciprocating motion, the transverse reciprocating motion of the sliding block 602 drives the transverse displacement of the movable tube 2, so that the air inlet unit 3 located in the cover 102 makes a reciprocating motion, and the reciprocating motion of the air inlet unit 3 cleans the metal filter screen 4.
