[0032] During the use of the welding fume purifier, the threaded rod 22 is rotated to drive the support pad 23 to descend, thereby fixing the welding fume purifier and preventing the welding fume purifier from moving during operation.

[0033] The connecting component includes a base 31 and a telescopic bent suction pipe 33. The bottom surface of the base 31 is detachably connected to the upper surface of the shell 1. The upper surface of the base 31 is detachably connected to the bottom of the regulating valve 32 of the regulating component. The upper surface of the regulating valve 32 of the regulating component is fixedly connected to one end of the telescopic bent suction pipe 33.

[0034] The regulating assembly regulating valve 32 includes a connecting valve 321, the bottom end of which is detachably connected to the inner wall of the base 31, a through groove 3211 is provided on the inner wall of the connecting valve 321, and a rotatably connected 322 is provided on the inner wall of the connecting valve 321, and a through groove 3221 and a limit groove 3222 are provided on the inner wall of the connecting valve 322.

[0035] The top of 322 is rotatably connected with a connecting valve 2 324, the inner wall of the connecting valve 2 324 is provided with a through groove 3241, the outer surface of the connecting valve 2 324 is fixedly connected with a limiting rod 3242 which is slidably connected to the inner wall of the limiting groove 3222, the upper surface of the connecting valve 2 324 is fixedly connected to one end of the connecting tube 323, and one end of the connecting tube 323 is fixedly connected to one end of the telescopic bending suction pipe 33.

[0036] During the use of the welding fume purifier, the suction angle can be adjusted by bending the telescopic bending suction pipe 33. If the suction strength needs to be adjusted, 322 can be rotated under the limit of 3442 and the limit groove 3222 to change the docking area of ​​the second through groove 3221, the third through groove 3241 and the first through groove 3211, thereby adjusting the suction strength of the welding fume purifier.

[0037] The purification component includes a HEPA high-efficiency filter 45, an activated carbon filter 46 and an exhaust fan 47. The outer surfaces of the activated carbon filter 46 and the HEPA high-efficiency filter 45 are detachably connected to the inner wall of the shell 1, the input end of the exhaust fan 47 is fixedly connected to the bottom surface of the activated carbon filter 46, the bottom of the exhaust fan 47 is detachably connected to the inner wall surface of the shell 1, and the output end of the exhaust fan 47 is detachably connected to the inner wall side of the shell 1.

[0039] When using the welding fume purifier, first start the exhaust fan 47 to generate negative pressure inside the shell 1, so that the dust suction unit 3 sucks the smoke. After the smoke generated during the welding process is sucked into the shell 1 through the dust suction unit 3, it passes through the HEPA high-efficiency filter 45 and the exhaust fan 47 in turn. The cooperation between the HEPA high-efficiency filter 45 and the exhaust fan 47 can assist in filtering and purifying the smoke, and finally be discharged from the output end of the exhaust fan 47. During the filtering process of the screw rod 42, dust will accumulate on the upper surface of the screw rod 42. By starting the drive motor 41, the drive end of the drive motor 41 drives the screw rod 42 to rotate, thereby cooperating with the limit slide rod 43 to drive the cleaning plate 44 to move in the horizontal direction, so that the dust on the upper surface of the HEPA high-efficiency filter 45 can be cleaned, and the dust is cleaned to both ends of the HEPA high-efficiency filter 45, so as to facilitate centralized treatment of the dust.

[0040] The following is a detailed description of the working principle of this easily adjustable welding fume purifier.

[0041] like Figure 1-5 As shown, when the welding fume purifier is used, the welding fume purifier is moved to an appropriate position, and then the support pad 23 is driven down by rotating the threaded rod 22 to fix the welding fume purifier. When the welding fume purifier is used, the exhaust fan 47 is first started to generate negative pressure inside the shell 1, so that the dust suction unit 3 sucks the smoke, and then the suction angle is adjusted by bending and telescoping the bending suction pipe 33. If it is necessary to adjust the suction intensity, by rotating 322, 322 is rotated under the limit of 3442 and the limit groove 3222, the docking area between the through groove 2 3221 and the through groove 3241 and the through groove 1 3211 is changed, thereby adjusting the suction force of the welding fume purifier. When a negative pressure is generated during welding, the suction unit 3 sucks the smoke. After the generated smoke and dust is sucked into the interior of the shell 1 through the dust collection unit 3, it passes through the HEPA high-efficiency filter 45 and the exhaust fan 47 in turn. The cooperation between the HEPA high-efficiency filter 45 and the exhaust fan 47 can assist in filtering and purifying the smoke and dust, and finally be discharged from the output end of the exhaust fan 47. During the filtering process of the screw rod 42, dust will accumulate on the upper surface of the screw rod 42. By starting the drive motor 41, the drive end of the drive motor 41 drives the screw rod 42 to rotate, thereby cooperating with the limiting slide rod 43 to drive the cleaning plate 44 to move in the horizontal direction, so that the dust on the upper surface of the HEPA high-efficiency filter 45 can be cleaned, and the dust is cleaned to both ends of the HEPA high-efficiency filter 45, so as to facilitate centralized treatment of the dust.

[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
