[0035] See also Figure 1-7 , a method for using the smoke remover, the method comprising the following steps: S1: Connect one end of the connecting hose 2 to the air suction joint 14, lay the connecting hose 2 on the surface of the gun barrel 3 along the multiple holders 31, and install the cigarette butt 4 on the surface of the conductive nozzle 33 through the central clamping mechanism 5; adjust the distance between the air suction port 43 and the end surface of the conductive nozzle 33, and connect the other end of the connecting hose 2 to the oblique joint pipe 41; S2: Install the annular filter plate 61 inside the air inlet 43, insert the convex plate 62 into the notch groove 47 to achieve positioning, and use the clamp 64 to fix both sides of the annular filter plate 61 to prevent it from falling off; S3: Start the brushless motor inside the machine body 1, which drives the pump body to work and form suction. The welding operation is performed by controlling the position of the conductive nozzle 33 by holding the gun rod 3. The smoke generated during the welding process is sucked in through the air suction port 43, and enters the machine body 1 through the annular groove 42, the oblique butt pipe 41 and the connecting hose 2 for filtration. The annular design of the annular groove 42 realizes multi-directional smoke removal in the welding area.

During the rotation of the rotating ring 54, the three rotating plates 51 can be driven to rotate synchronously by the mutual engagement of the convex teeth 55 and the incomplete tooth surface 53. During installation, the clamping rod 52 is moved to the center position to squeeze and fix the conductive nozzle 33, and ensure that the cigarette removal head 4 is concentric with the conductive nozzle 33 to adapt to the installation work of the conductive nozzle 33 with different diameters, and then the distance between the air suction port 43 and the end of the conductive nozzle 33 is consistent, thereby improving the smoke removal efficiency; During the smoke removal process, large particles of welding slag caused by welding will be filtered by the large particle filtering mechanism 6 to prevent large particles of foreign matter from being sucked into the annular groove 42 and causing blockage. When the foreign matter on the surface of the annular filter plate 61 is too large to affect the smoke removal effect, the annular filter plate 61 can be removed to clean its surface. Due to the presence of the spring 66, the pressure plate 65 always has a force away from the axis of the smoke removal head 4, so that the front end clamp 64 can enter the notch groove 47 to fix the annular filter plate 61 to prevent the annular filter plate 61 from falling off during use. When removing the annular filter plate 61, the pressure plate 65 can be pressed at the same time to improve the convenience of installing or removing the annular filter plate 61.
