The fume extracting mechanism 20 comprises a fume extracting duct 21 and a connecting unit 22 for rapidly separating the welding fume from the tin dross and storing the tin dross.
As shown in fig. 2, the connection unit 22 includes a connection pipe 223 fixedly connected to the body 10 and communicating with the smoke pumping pipe 21. The connecting pipe 223 is disposed toward the welding region of the body 10, and an inner cavity of the connecting pipe is sequentially provided with a limiting pipe 222 and a rotating module 224 for rapidly separating welding fume from tin slag from bottom to top. An accommodating space 225 for storing the solder dross is formed between an outer wall of the limiting pipe 222 and an inner wall of the connecting pipe 223. Through setting up accommodation space 225, store the dross that rotation module 224 separated, not only can prevent effectively that the dross from dropping back to the welding area of body 10 and influencing the welding, be convenient for moreover follow-up retrieve the dross and recycle, improve the utilization ratio of resource.
In practical use, the end of the smoke exhaust pipe 21 far away from the connecting pipe 223 is connected with an external negative pressure device. When the body 10 of the utility model starts to perform welding work, the negative pressure equipment is synchronously opened, and the smoke pumping pipeline 21 and the connecting pipeline 223 generate suction force to absorb welding smoke and tin slag generated by welding. Under the effect of negative pressure, the welding fume and the welding slag enter the inner cavity of the connecting pipeline 223 together, meanwhile, the flowing gas drives the rotating module 224 to rotate, the fume sequentially passes through the limiting pipeline 222 and the rotating module 224 and then enters the fume pumping pipeline 21, and the tin slag is blocked by the rotating module 224 and cannot continue to advance after passing through the limiting pipeline 222, moves towards the direction of the inner wall of the connecting pipeline 223 under the action of centrifugal force generated by rotation of the rotating module 224, and finally drops to the accommodating space 225 under the action of gravity.
