[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a cooling structure of a handheld laser welding machine. Figure 1-Figure 2, including a cooling hood 1, a fixed edge 5 is fixed to the outer wall of the bottom end of the cooling hood 1, which is convenient for connecting and fixing with the welding frame, a connecting pipe 3 is installed at the top of one side of the cooling hood 1, and a hose is used to connect the connecting pipe 3 and an external cooling pump to facilitate pumping the coolant into the cooling hood 1, and a positioning port 2 is opened at the center of the top of the cooling hood 1 to facilitate placing the welding gun head of a handheld laser welding machine for positioning and cold cutting, and a placement rack 6 is provided on one side of the cooling hood 1, the placement rack 6 is fixed to the side wall of the cooling hood 1, and both sides of the top of the placement rack 6 are integrated with a limit baffle 7, which can set up the handheld laser welding machine for convenient hanging cooling, simple structure, and easy operation.

[0021] like Figure 3 As shown, a water-cooling cooling frame 9 is installed inside the cooling cover 1, and a connector 10 is fixed on one side of the top of the water-cooling cooling frame 9. The connector 10 and the connecting pipe 3 are connected by a hose, and the connector 10 extends to the inside of the water-cooling cooling frame 9, so that the water pipe can be input into the water-cooling cooling frame 9. The bottom side wall of the water-cooling cooling frame 9 is connected to a circulating water pipe 12, and the circulating water pipe 12 extends to the inside of the water-cooling cooling frame 9. The water-cooling cooling frame 9 is set to a hollow structure to facilitate the circulation of the coolant, and the inner wall of the water-cooling cooling frame 9 is equidistantly distributed with a plurality of cooling nozzles 11, and a base frame 13 is fixed to the bottom end of the water-cooling cooling frame 9. A backwash nozzle 14 is installed on the base frame 13, which can cool the welding gun head with water at 360 degrees to improve the cooling efficiency, and at the same time, it can also wash the dust on its outer wall.

[0022] Combination Figure 4 As shown, a filter seat 8 is installed at the bottom of the water-cooling frame 9, the interior of the filter seat 8 is connected to a drainage base 4, the bottom of the drainage base 4 is connected to a drainage pipe 16, and a removable filter screen 15 is provided inside the filter seat 8.
