The filter screen 20 and the purification chamber 103 are fixedly installed with a fixing rod 18 below the lower conical filter screen 20, and an L-shaped guide tube 21 is rotatably installed on the fixing rod 18. The upper end of the L-shaped guide tube 21 is inclined to adapt to the lower surface of the lower conical filter screen 20. An opening 211 is provided on the side of the L-shaped guide tube 21 close to the surface of the lower conical filter screen 20. A scraper 22 is fixedly installed on the opening 211. The upper end of the scraper 22 is slidably installed on the lower surface of the lower conical filter screen 20. The box body 10 is slidably installed with a collecting box 15 at the lower end of the fixing rod 18.

[0026] In this embodiment, one end of the L-shaped conduit 21 close to the fixed rod 18 passes through the outer surface of the fixed rod 18, and two blocking rods 212 are fixedly installed on both sides of the opening 211 at the upper end of the L-shaped conduit 21. The two blocking rods 212 are respectively arranged at both ends of the scraper 22.

[0033] In this embodiment, a stove door 14 is provided on one side of the lower end of the air inlet 11 of the combustion chamber 101, and one side of the stove door 14 is hinged to the surface of the box body 10. When firewood or coal is used for combustion, the firewood or coal is inserted into the lower end of the inner wall of the combustion chamber 101 through the stove door 14, and then the firewood or coal is ignited to burn the organic waste gas entering through the air inlet 11.
