[0002] Welding fume purifiers are used for the purification of soot and dust generated in processes such as welding, cutting, and grinding, as well as the recovery of rare metals and precious materials. They can purify a large number of tiny metal particles suspended in the air that are harmful to the human body. They have the characteristics of high purification efficiency, low noise, flexible use, and small floor area.

[0003] After the welding fume purifier is used for a period of time, it is necessary to clean the internal filter screen. However, most of the existing welding fume purifiers are inconvenient to disassemble and assemble the internal filter screen, and the entire device cannot be used when disassembling and cleaning the filter screen. For this reason, we propose a mobile welding fume purifier. Content of the Utility Model

[0027] Figures 1-3 Shown is a schematic structure diagram of an embodiment of a mobile welding fume purifier of the present utility model. Please refer to Figures 1-3 , A mobile welding fume purifier of this embodiment, its main part includes a welding fume purifier housing 100, a dust suction assembly 200 and a rotating filter assembly 300.

[0028] Four moving wheels 101 are provided at the bottom of the welding fume purifier housing 100. A handle 102 is fixed on the upper side of the side wall of the welding fume purifier housing 100. A vertical slot is opened on the outer wall of the welding fume purifier housing 100. Preferably, in this embodiment, foot brakes are provided on two of the moving wheels 101 near the handle 102 end. The foot brakes provided on the moving wheels 101 facilitate the operator to lock the moving wheels 101 through the foot brakes to ensure the stable placement of the device when the device is moved to a designated position for use. A circular ring plate 103 communicating with the welding fume purifier housing 100 is provided at the lower end of the side wall of the welding fume purifier housing 100 where the handle 102 is located. An exhaust fan 104 is provided inside the circular ring plate 103. The exhaust fan 104 provided in the circular ring plate 103 can drive the air flow inside the welding fume purifier housing 100, thereby accelerating the purification of the fumes by the device. A connecting portion 105 is fixed on the side wall of the welding fume purifier housing 100. The circular ring plate 103 is threadedly connected to the connecting portion 105. The circular ring plate 103 is threadedly installed on the welding fume purifier housing 100 under the action of the connecting portion 105. Later, the operator can manually rotate it to remove it for overhauling the internal exhaust fan 104.

[0029] The dust suction assembly 200 includes two air extraction pumps 210 provided at the upper end of the welding fume purifier housing 100, an air extraction pipe 220 provided on the air extraction pump 210, and an air extraction hood 230 provided at the end of the air extraction pipe 220.
