DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A soldering fume removal assembly for circuit board processing includes a heat insulation ring 6, which is fixedly connected to the pen holder of an electric welding pen 4 by bolts. A gathering cover 7 is fixedly connected to the outer wall of the heat insulation ring 6. The material of the heat insulation ring 6 is selected to be heat-resistant rubber, and the material of the gathering cover 7 is selected to be a transparent acrylic plate material, which is convenient for observing the welding conditions of electrical components inside the gathering cover 7. The heat insulation ring 6 prevents the heat of the pen holder of the electric welding pen 4 from being transferred to the entire soldering fume removal assembly.

[0022] The top of the gathering hood 7 is symmetrically fixedly connected with the mounting plates 1, and the bottom of one group of the mounting plates 1 is fixedly connected with the micro fan 2, the air inlet end of the micro fan 2 is fixedly connected with the exhaust pipe 21, the exhaust pipe 21 is fixedly connected to the top of the docking box 9, the bottom of the docking box 9 is fixedly connected to one end of the connecting pipe 3, and the other end of the connecting pipe 3 is fixedly connected to the gathering hood 7, and a storage component for storing activated carbon particles is arranged inside the docking box 9.

[0023] The storage assembly includes a storage box 8 and a diffusion cover 12. A storage slot 10 is provided on the top of the storage box 8. A handle 81 is fixedly connected to the side of the storage box 8. The upper and lower sides of the storage box 8 are fixedly connected to the diffusion cover 12. The storage box 8 is filled with activated carbon particles. A handle 81 is fixedly connected to the side of the storage box 8. The storage box 8 is movably inserted into the side of the docking box 9. The setting of the diffusion cover 12 facilitates the even guidance of exhaust gas to the activated carbon particles.

[0024] A docking hole 11 is provided at the end of the diffusion cover 12.

A handle 5 is vertically fixedly connected to the top of the side of the mounting plate 1, and finger grooves 51 are equidistantly provided at the bottom of the handle 5 to facilitate workers to hold the entire device.

[0025] The specific implementation steps and principles of the utility model are as follows:

[0026] When a worker holds the welding pen 4 for welding, the worker holds the finger groove 51 of the grip 5 and starts the micro fan 2. The micro fan 2 draws the released smoke and harmful gases generated during welding near the gathering hood 7 into the activated carbon box through the connecting pipe 3, the docking box 9, and the exhaust pipe 21. The released smoke and harmful gases generated during welding are absorbed by the activated carbon particles.

[0027] When the activated carbon particles in the storage box 8 need to be replaced, the storage box 8 is pulled out from the docking box 9 by the handle 81 , and the activated carbon particles are pulled out from the storage box 8 .
