[0028] First, air enters the gas tank body 1 through the air inlet pipe 5. When the air passes through the connecting pipe 6, the particulate impurities in the air are isolated on the surface of the filter plate 704 through the filter plate 704 in the filter assembly 7. Then, the fine dust in the air is adsorbed by the adsorption plate 702, so that the clean air enters the gas tank body 1 for storage.
