A plurality of exhaust openings are arranged on the lower side of the exhaust duct, and all the exhaust openings are communicated with the inner cavity of the welding room body; it also includes a plurality of suction devices corresponding to the number of exhaust ducts on the wall on the side where the overhead rail is located. A telescopic air duct is fixedly arranged at the suction opening of the suction device, and the telescopic air duct can be hermetically attached to the open structure of the corresponding exhaust duct.

[0006] Further, the telescopic air duct includes a fixed air duct, a movable air duct, and a cylinder. One end of the fixed air duct is fixedly connected to the suction opening of the suction device. The other end of the fixed air duct is internally inserted with the movable air duct. The cylinder block of the cylinder is arranged on the outside of the fixed air duct, and the piston rod of the cylinder is arranged on the outside of the movable air duct. By driving the movable air duct to move telescopically in the fixed air duct through the cylinder, and through the telescopic movement of the piston rod, the end of the movable air duct can be butted with the opening of the exhaust duct in a matching manner.

[0007] Further, a sealing ring is arranged at the end of the movable air duct facing the exhaust duct, so that the telescopic air duct can be hermetically attached to the open structure of the corresponding exhaust duct through the sealing ring.
