[0032] The filter device body 100 is provided with a receiving cavity, and a partition plate 600 is provided in the receiving cavity, which divides the receiving cavity into an upper receiving cavity and a lower receiving cavity.
[0033] An upper exhaust vent 900 is provided on the partition plate 600, and an exhaust motor 800 is provided at the lower end of the partition plate 600. The exhaust motor 800 is used to allow the gas in the upper cavity to enter the upper exhaust vent 900.
[0034] A vacuum motor 500 is installed inside the upper cavity, and the vacuum motor 500 is used to generate negative pressure at the vacuum port 170.
[0035] A first fireproof plate 130, a second fireproof plate 140, a first purification plate 150, and a second purification plate 160 are arranged sequentially from high to low on the partition plate 600.
[0036] In some embodiments, a dust suction port 170 is provided at the upper end of the filter device body 100. The dust suction motor 500 generates negative pressure in the dust suction port 170, and the harmful fumes generated during welding enter the upper cavity of the filter device body 100 through the dust suction port 170. A first fireproof plate 130, a second fireproof plate 140, a first purification plate 150, and a second purification plate 160 are provided in the upper cavity. The exhaust fan motor 800 causes the fumes entering the upper cavity to pass through the first fireproof plate 130, the second fireproof plate 140, the first purification plate 150, and the second purification plate 160 in sequence before entering the lower cavity and being discharged from the lower cavity.
[0037] This allows the welding fumes to pass through the filter body 100, filtering out harmful fumes from the air. This enables welding operations to be carried out even in poorly ventilated environments, preventing the spread of welding fumes and avoiding any impact on the air quality at the work site, thus protecting the health of the workers.
[0038] Reference Figure 2 In an optional embodiment, the filter holes of the first fireproof plate 130 and the second fireproof plate 140 become progressively smaller, and the first fireproof plate 130 and the second fireproof plate 140 are made of metal.

Both the first fireproof plate 130 and the second fireproof plate 140 are made of metal. Sparks generated during welding enter the upper cavity and are intercepted by the first fireproof plate 130 and the second fireproof plate 140, preventing them from entering the first purification plate 150. The first fireproof plate 130 is used to intercept inhaled particles and sparks, while the second fireproof plate 140 is used to intercept fine particles and sparks.
[0041] The first purification plate 150 has a smoke purification layer, which includes a three-stage composite meltblown fabric. The first purification plate 150 is used to absorb fine particles and smoke. The second purification plate 160 has an activated carbon purification layer, which includes activated carbon composite meltblown fabric. The second purification plate 160 is used to absorb even finer particles and smoke.
[0042] In an optional embodiment, an installation chamber 700 is provided inside the upper cavity, and the vacuum motor 500 is disposed inside the installation chamber 700; perforations are provided on all sides of the installation chamber 700.
[0043] An installation chamber 700 is provided in the upper cavity, and a vacuum motor 500 is installed in the installation chamber 700. Perforations are provided in the circumference and bottom of the installation chamber 700.

[0046] After a period of use, the first fireproof plate 130, the second fireproof plate 140, the first purification plate 150, and the second purification plate 160 need to be replaced and maintained. The first fireproof plate 130 and the second fireproof plate 140 can be removed from the upper cavity, and the particles on the first fireproof plate 130 and the second fireproof plate 140 can be cleaned and put back in. The first purification plate 150 and the second purification plate 160 are generally maintained by direct replacement to ensure the filtration effect of the filter device body 100.

[0054] The dust extraction motor 500 of the filter device body 100 of the device for absorbing and filtering welding fumes provided by this utility model causes the fumes to enter the upper cavity through the dust extraction port 170. The fumes entering the upper cavity pass through the first fireproof plate 130, the second fireproof plate 140, the first purification plate 150 and the second purification plate 160 in sequence before entering the lower cavity, thus achieving the filtration of fumes. In this way, welding fumes can be avoided even in poorly ventilated areas, reducing the impact of welding on the air quality at the site and ensuring the health of the workers.
