[0019] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0020] Example 1:

[0021] like Figure 1-2 As shown in the figure, the portable high-altitude welding fume collection device provided in this embodiment of the utility model includes a fume suction end 1 and a housing 2 connected to the fume suction end 1; the housing 2 is provided with a smoke exhaust fan 3 and a filter assembly, and a high-altitude fixing connector 5 is connected to the housing 2. The high-altitude fixing connector 5 is used to fix this device in the air, and the smoke exhaust fan 3 provides suction and smoke exhaust power, so that the fume enters from the fume suction end 1, passes through the filter assembly, and is discharged from the smoke exhaust port 6.

[0022] Specifically, the filter assembly includes a filter housing 41 and a filter element 42. The filter housing 41 has air inlets around its perimeter and a baffle 43 at its lower end, which guides airflow to the perimeter of the filter housing 41. An air outlet channel 44 is located at the center of the filter housing 41, guiding airflow to the exhaust fan 3. The filter housing 41 can be a cylindrical filter housing with air inlets on its circumference, which can be several air inlets 45. The filter element 42 is a cylindrical filter element, which is built into the filter housing 41. The center of the cylindrical filter element is the air outlet channel 44. The filter housing 41 and the lower housing 21 can be detachably connected by bolts to facilitate the disassembly of the filter housing 41. The lower housing 21 can be equipped with a bracket. The filter housing 41 can be detachably connected to the lower housing 21 by bolts. Alternatively, several fixing ears can be provided on the upper edge of the filter housing 41, which can be detachably connected to the lower housing 21 by bolts. Larger dust particles will be blocked by the baffle 43 and the air inlet of the filter housing 41 and fall to the bottom of the lower housing 21. Therefore, the lower housing 21 can be equipped with a dust collection drawer 23 for collection.

[0023] Specifically, the high-altitude fixed connection 5 is a safety strap or a U-shaped clamp, which can stabilize the device in the air, such as by fixing it to the steel column or steel beam of the steel structure.

[0024] In some instances, for ease of disassembly and maintenance, the housing 2 includes a lower housing 21 and an upper housing 22. The lower housing 21 and the upper housing 22 are detachably connected. The lower end of the lower housing 21 is connected to the dust collection end 1. The filter assembly is disposed inside the lower housing 21. The exhaust fan 3 is disposed inside the upper housing 22. The top of the upper housing 22 is the exhaust port 6. The lower housing 21 and the upper housing 22 are connected by a threaded connection or a flange connection, and a sealing gasket can be provided at the connection point for sealing.

[0025] In some embodiments, the housing 2 is provided with a storage battery 7, which powers the device so that it does not need to be connected to AC power, thereby improving portability and flexibility of use.

[0026] In some embodiments, the dust suction end 1 includes a dust suction hood 11 and a connecting pipe 12. The connecting pipe 12 is a universal dust suction hose. The universal dust suction hose can be used to adjust the orientation of the dust suction end 1 at will according to the dust suction needs, making it highly adaptable.

[0027] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
