[0022] The specific workflow is as follows: During operation, the fuel is burned in the heating chamber 6, and the external air is blown into the heat exchange tube 8 through the fan interface 3 by an external blower. The high-temperature flue gas in the heating chamber 6 performs heat exchange with the heat exchange tube 8, and is connected to the hot air pipe interface 4 through an external pipeline. The hot air after heat exchange is discharged through the hot air pipe interface 4. At the same time, a proper amount of clean water can be added to the water inlet pipe 10 to heat and form water vapor to adjust the humidity of the hot air. At the same time, the high-temperature flue gas after heat exchange is filtered and discharged through the gas outlet component 9, and the coal ash after the fuel combustion can be collected through the ash outlet component 5. When the high-temperature flue gas in the heating chamber 6 is discharged, the exhaust mechanism 92 is opened so that the exhaust mechanism 92 draws the high-temperature flue gas after heat exchange upwards, and at the same time, the cleaning mechanism 96 moves upwards on the guide rod 94 through the suction force generated by the exhaust mechanism 92, so that the cleaning mechanism 96 can clean the inner side of the chimney 91, and at the same time, the flue gas after heat exchange is purified by the suction force of the exhaust mechanism 92 through the filter mechanism 93, and the purified flue gas is discharged through the exhaust mechanism 92; When the suction force generated by the exhaust mechanism 92 drives the connecting plate 961 to move upward on the guide rod 94, the connecting plate 961 drives the scraper 963 to clean and scrape the inner side of the chimney 91, thereby preventing the flue gas after heat exchange from continuously passing through the chimney 91 for discharge, and a large amount of smoke and dust impurities will remain on the inner side of the chimney 91. If it is not cleaned for a long time, the inner side of the chimney 91 will be corroded. By adding a large amount of activated carbon particles into the filter shell 931, when the exhaust mechanism 92 drives the flue gas to pass through the filter shell 931, the flue gas after heat exchange is fully in contact with the activated carbon particles in the filter shell 931, so that the impurities in the flue gas are adsorbed and purified. At the same time, the rotating shaft 933 drives the rotating frame 934 to rotate in the inner cavity of the filter shell 931 through the suction force of the exhaust mechanism 92, so that the rotating frame 934 fully stirs the activated carbon particles in the filter shell 931. When the rotating frame 934 follows the rotating shaft 933 to stir the activated carbon particles, the arc plate 935 can follow the rotating frame 934 to drive the multiple connecting shafts 936 to stir the activated carbon particles in a fully reverse direction, so that when the flue gas passes through the filter shell 931, the activated carbon particles can fully contact the exhaust gas. At the same time, by fully stirring the activated carbon particles, the thickness of the concentration boundary layer can be reduced, the pollutants are promoted to diffuse faster into the activated carbon, the adsorption rate is increased, and the pollutants are evenly distributed in the entire fluid, avoiding the occurrence of local saturation. When the multifunctional circulating heating hot air furnace stops working and it is necessary to clean the coal ash after combustion, the suction mechanism 55 is opened to suck the coal ash into the ash storage shell 52, and the ash outlet door 53 is opened to clean the coal ash in the ash storage shell 52. When the suction mechanism 55 is working, the suction force generated causes the connecting frame 58 to move downward driven by the connecting shaft 510, and the contact mechanism 57 rotates at the top of the suction mechanism 55, thereby preventing the coal ash entering the ash storage shell 52 from accumulating on the suction mechanism 55 in large quantities, resulting in poor ventilation effect of the suction mechanism 55. At the same time, when cleaning the coal ash, the suction force of the suction mechanism 55 is used to prevent the coal ash from falling into the ash storage shell 52 and causing a large amount of dust. When the suction mechanism 55 stops working, the connecting frame 58 is reset by the stretching of the first spring 511 and moves upward. At the same time, the connecting frame 58 drives the extrusion rod 591 to move upward, so that the extrusion rod 591 drives the ejector pin 595 to eject the coal slag stuck in the mesh plate 56, thereby preventing the coal slag from being stuck in the mesh plate 56 and causing the mesh plate 56 to be blocked. At the same time, when the ejector pin 595 is in extrusion contact with the coal slag stuck in the mesh plate 56, when the extrusion force between the coal slag and the ejector pin 595 is greater than the stretching force of the second spring 596, the ejector pin 595 moves in the notch 592 through the slide bar 594 and the slide block 593, and at the same time, the extrusion buffer of the second spring 596 is used to prevent the ejector pin 595 from being damaged when the extrusion force between the ejector pin 595 and the coal slag stuck in the mesh plate 56 is too large. At the same time, when the coal ash enters the inner cavity of the ash storage shell 52 through the suction force of the suction mechanism 55, the motor 576 is turned on, and the rotating shaft 571 is driven to rotate through the output end of the motor 576. The rotating shaft 571 also drives the first round rod 572 to rotate, so as to contact and rotate with the top of the suction mechanism 55 through the contact rod 573. At the same time, the second round rod 574 drives the block 575 to contact and rotate at the top of the suction mechanism 55, so as to avoid a large amount of coal slag from accumulating in the middle of the suction mechanism 55, and then blocking the air outlet of the suction mechanism 55. The block 575 contacts and rotates the coal ash accumulated on the top of the suction mechanism 55, so that the coal ash can be rotated to the edge of the top of the suction mechanism 55, so as to facilitate the subsequent opening of the ash outlet door 53 to clean the coal ash in the ash storage shell 52.
