[0037] A purification component 4, which is arranged inside the connecting tube 1;

[0038] The purification assembly 4 includes a purification shell 41 arranged inside the connecting cylinder 1, a purification component 42 arranged inside the purification shell 41, and a limiting component 43 arranged between the purification component 42 and the purification shell 41. Preferably, there are two purification components 42, and the two purification components 42 have different sizes. The purification component 42 is a filter cartridge.

[0040] Among them, the limiting member 43 includes a limiting seat 431 arranged at the top of the purification member 42 and a fixing seat 432 arranged at the bottom of the purification member 42. A threaded hole is opened at the center of the top surface of the purification shell 41. The limiting seat 431 is threadedly connected inside the threaded hole. The fixing seat 432 is installed at the top center of the purification shell 41. Preferably, circular grooves for limiting the limiting member 43 are opened on the opposite sides of the limiting seat 431 and the fixing seat 432.

[0041] A limiting ring 44 is fixedly disposed on the inner wall of the connecting tube 1 , and the bottom surface of the limiting ring 44 abuts against the top surface of the purification shell 41 .

[0042] Among them, a mounting assembly 5 is provided between the connecting tube 1 and the smoke recovery tube 2;

[0043] The mounting assembly 5 includes a fixing cylinder 51 mounted on the top of the smoke recovery cylinder 2, a mounting block 52 disposed on the top of the fixing cylinder 51, and a positioning unit 53 disposed between the mounting block 52 and the connecting cylinder 1. There are two groups of positioning units 53, and the two groups of positioning units 53 are disposed on the top of the fixing cylinder 51 in a relative manner. By providing the two groups of positioning units 53, the smoke recovery cylinder 2 is fixedly connected to the connecting cylinder 1.

[0044] The positioning unit 53 includes a storage groove arranged on the inner side of the mounting block 52, one end of an extrusion piece 531 installed on the side wall of the storage groove, one end of a positioning column 532 fixedly connected to the other end of the extrusion piece 531, and a positioning hole 533 arranged on the inner wall of the connecting tube 1 and matched with the size of the other end of the positioning column 532.
