Technical Field

[0001] The utility model relates to the technical field of smoke exhaust devices for electric welders, in particular to a portable smoke exhaust device for electric welders. Background Art

[0002] An electric welder is a device used to weld metals by heating two pieces of metal to a molten state and then joining them together. An electric welder usually consists of a power supply, a control system, and a welding gun. During welding, a large amount of smoke and fumes are generated, which may contain harmful substances and pose a potential risk to workers' health. Therefore, a fume exhaust device is required to exhaust the smoke and fumes.

[0003] After searching, the existing Chinese patent announcement number is: CN217290845U, which provides a smoke exhaust device suitable for an electric welder. The patent accelerates the smoke generated during welding into the exhaust mechanism through the blowing mechanism, and the toxic smoke is discharged to a position away from the welder through the suction part, thereby reducing the welder's inhalation of toxic gases.

[0004] Although the above patent can perform smoke exhaust operations on toxic smoke, the above smoke exhaust device suitable for electric welding machines still has the following problems: electric welding requires carrying an electric welding gun for picking up and moving, and this smoke exhaust structure is large in size, which is not conducive to portability and can be used with the electric welding gun for smoke exhaust at any time, and has limited flexibility.

[0005] In view of the above problems, a portable fume exhaust device for welding machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0036] Combination Figure 1 and Figure 2 The portable electric welding machine smoke exhaust device of the utility model comprises a main jacket 1, an electric welding gun 2 is arranged in the main jacket 1, the front and rear ends of the outer wall of the main jacket 1 are fixedly connected with a first magnet 3, the first magnet 3 cooperates with the second magnet 17 to facilitate the movable baffle 21 to be close to the main jacket 1 and to be close to the auxiliary jacket 4 through the sealing brush 19 to form a relatively closed space, and the auxiliary jacket 4 is slidably connected in the main jacket 1.

[0037] Combination Figure 3 and Figure 4 The upper and lower ends of the inner wall of the auxiliary jacket 4 are fixedly connected with tooth plates 5, which facilitate sliding fixation between the main jacket 1 and the auxiliary jacket 4. The upper and lower ends of the right side of the inner wall of the main jacket 1 are fixedly connected with fixing rods 7, and the lower end of the fixing rod 7 is fixedly connected with a first spring 8. A limiting component is arranged at the bottom of the first spring 8. The limiting component includes a telescopic sleeve 6, the bottom of the inner wall of the telescopic sleeve 6 is fixedly connected to the bottom of the first spring 8, and the telescopic sleeve 6 is slidably connected to the outer wall of the fixing rod 7. A clamping block 9 is fixedly connected to the bottom of the telescopic sleeve 6, and the clamping block 9 is against the outer wall of the tooth plate 5. A positioning screw 10 is threadedly connected to the left side of the inside of the main jacket 1.

[0038] Combination Figure 5 , Figure 6 and Figure 7The top of the inner wall of the main jacket 1 is slidably connected with a slider 11, and the top of the slider 11 is fixedly connected with a conical sleeve 12. The conical sleeve 12 exhausts air so that the smoke formed by electric welding enters the exhaust port 18 through the conical sleeve 12. The front end of the inner wall of the slider 11 is slidably connected with a limiting block 13, and the rear end of the limiting block 13 is fixedly connected with a second spring 20, and the rear end of the second spring 20 is fixedly connected to the inner wall of the slider 11. Through the elastic effect of the second spring 20, the limiting block 13 is squeezed outward. When it moves to the card slot where the squeezing block 14 is located (not marked in the figure), the limiting block 13 cooperates with the second spring 20 to snap into the card slot, thereby completing the fixation of the slider 11. The front end of the inner wall of the main jacket 1 is provided with an extrusion assembly, and the extrusion assembly includes a slide rod 15. The slide rod 15 is slidably connected to the front end of the inner wall of the main jacket 1. The end is fixedly connected with an extrusion block 14, and the front end of the slide bar 15 is fixedly connected with a pushing handle 16. By pressing the pushing handle 16, the slide bar 15 is pushed to move, thereby pushing the extrusion block 14 out of the slot, which is convenient for taking out the slider 11. A movable baffle 21 is fixedly connected to the right side of the bottom of the conical sleeve 12, and a dense sealing brush 19 is fixedly connected to the bottom of the left side of the movable baffle 21. The movable baffle 21 is made of soft leather and can be opened and deformed at will. It cooperates with the sealing brush 19 to fit closely with the auxiliary jacket 4 to form a relatively closed space, which is convenient for the exhaust port 18 to perform smoking and exhaust operations. The front and rear ends of the left side of the movable baffle 21 are fixedly connected with the second magnet stone 17. The second magnet stone 17 cooperates with the first magnet stone 3 to fix its movable baffle 21, and the right side of the movable baffle 21 is fixedly connected with the exhaust port 18.

[0039] Working principle: when in use, first install the main jacket 1 and the auxiliary jacket 4 to the welding gun 2. The installation method is to first insert the welding gun 2 into the main jacket 1, and then rotate the auxiliary jacket 4 so that the auxiliary jacket 4 rotates along the outer wall of the welding gun 2. During the rotation, the clamping block 9 will adaptively move up and down through the first spring 8 and the telescopic sleeve 6, so that the clamping block 9 can be clamped into the tooth plate 5, so that the auxiliary jacket 4 can slide one step in the main jacket 1 and be fixed. If it is necessary to reduce the size of the jacket formed between the main jacket 1 and the auxiliary jacket 4, the depth of sliding the auxiliary jacket 4 into the main jacket 1 on one side or both sides can be adjusted, and then the positioning screw 10 is rotated to make it threadedly matched with the main jacket 1, thereby squeezing the welding gun 2 inward to complete the auxiliary fixation, and then the slider 11 is used. It slides into the main jacket 1, and then through the elastic action of the second spring 20, it will follow an inclined surface (not marked in the figure) at the front end of the top right side of the main jacket 1 to make the limit block 13 shrink into the slider 11, and then when the extrusion force is lost, it will be stuck in the slot (not marked in the figure) where the extrusion block 14 is located, thereby completing the limit fixation of the slider 11, and then flip the movable baffle 21, and put the second magnet stone 17 on the first magnet stone 3, and its sealing brush 19 will adapt to the deformation of the outer wall of the main welding gun 2, and then the smoke exhauster (not marked in the figure) connected to the exhaust port 18 will operate so that the smoke generated by the electric welding passes through the conical sleeve 12 into the closed space formed by the movable baffle 21, the auxiliary jacket 4, the main jacket 1 and the sealing brush 19, and is discharged through the exhaust port 18.
