Under the action of the reciprocating lead screw sleeve 14, the rotation of the reciprocating lead screw 13 drives the toothed plate 11 to reciprocate.

[0029] The reciprocating lead screw 13 and the reciprocating lead screw sleeve 14 are existing structures. The reciprocating lead screw sleeve 14 is sleeved on the outside of the reciprocating lead screw 13, and as the reciprocating lead screw 13 rotates, the reciprocating lead screw sleeve 14 will move back and forth on the surface of the reciprocating lead screw 13.

The upper surface of the vehicle body 1 is fixedly connected with an air outlet 26 that communicates with the interior.

[0036] Working principle:

[0037] When using this mobile VOCs treatment machine, the operator moves the vehicle body 1 to the treatment location using the handle 24, then adjusts the pitch angle of the suction hood 4 using the connector 7. Next, the internal fan of the vehicle body 1 is started. The fan generates suction, drawing the gas to be purified from the suction hood 4 into the vehicle body 1. After passing through the filter plate 25 for adsorption and filtration, the gas is discharged from the outlet 26. The operator then turns on the switch of the first motor 15. The rotation of the output shaft of the first motor 15 drives the rotation of the extension rod 16, which in turn drives... The rotation of the reciprocating screw 13 drives the reciprocating screw sleeve 14 to reciprocate within the guide groove 12. The movement of the reciprocating screw sleeve 14 drives the toothed plate 11 to slide within the cavity 8. Since the toothed plate 11 and the gear 10 are meshed, the reciprocating movement of the toothed plate 11 drives the gear 10 to reciprocate. The rotation of the gear 10 drives the rotation of the rotating shaft 9, which in turn drives the rotation of the support shaft 6. The rotation of the support shaft 6 drives the swing of the connecting piece 7 and the suction hood 4, ultimately increasing the treatment range.

[0038] When the device is idle, the switch of the second motor 20 can be turned on. The rotation of the output shaft of the second motor 20 will drive the rotation of the threaded rod 18. The rotation of the threaded rod 18 will drive the sliding block 19 to slide inside the vertical groove 17. The movement of the sliding block 19 will drive the movement of the lifting plate 5. The movement of the lifting plate 5 will drive the movement of the support shaft 6, the connecting piece 7, and the suction hood 4 until the suction hood 4 is stored inside the storage box 2. Then, the staff can seal the storage box 2 through the sliding cover 21.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
