[0025] Impurities in the exhaust gas are filtered through the filter plate 31 to reduce corrosion to the inside of the cylinder body 2. The handle 322 is used to rotate the rotating rod 1 32 to drive the bevel gear 1 321 to rotate, and the bevel gear 2 33 is driven to rotate through the bevel gear 1 321, and then the rotating rod 2 34 is driven to rotate through the bevel gear 2 33, which can drive the strip plate 343 and the scraper 344 to rotate to clean the surface of the filter plate 31, so that the impurities attached to the surface of the filter plate 31 fall off, thereby avoiding clogging of the filter plate 31 and affecting the filtering effect of the exhaust gas.

The reverse force of the spring 385 pushes the top plate 387 to drive the sealing gasket 383 to press against the bottom end of the connecting pipe 37, thereby improving the sealing effect between the collecting box 38 and the connecting pipe 37.
