The furnace body 102 starts to heat up, and a large amount of smoke is generated inside the furnace body 102, which flows into the concave smoking pipe 103 and then enters the smoke exhaust pipe 104. The smoke is filtered by the filter 105 inside the smoke exhaust pipe 104 and then discharged. At the same time, the smoke exhaust pipe 104 can be reinforced again at the screw hole on the top of the smoke exhaust pipe 104.

[0032] There are four screw holes, two filters 105, the bottom of the smoke exhaust pipe 104 is fixedly connected to the top of the furnace body 102, and the inner wall of the furnace body 102 is threadedly connected with a bolt 106.

[0033] The control mechanism 2 includes a cabinet 201, a control panel 202 is fixedly connected to the inner wall of the cabinet 201, a main bracket 203 is fixedly connected to the right side of the cabinet 201, a cylinder rod 204 is fixedly connected to the inner wall of the main bracket 203, a furnace door 205 is fixedly connected to the bottom of the cylinder rod 204, and a sub-bracket 206 is arranged on the back of the main bracket 203. The control panel 202 inside the cabinet 201 is used to control the cylinder rod 204 under the inner wall of the main bracket 203 to rise so that the furnace door 205 rises. There are two cylinder rods 204, and there are two furnace doors 205. The main bracket 203 is arranged on the top of the bottom plate 101, and the main bracket 203 is fixedly connected to the top of the bottom plate 101, and the sub-bracket 206 is fixedly connected to the top of the bottom plate 101. A main bracket 203 is provided on the front of the furnace body 102, and the main bracket 203 is fixedly connected to the front of the furnace body 102, and a sub-bracket 206 is fixedly connected to the back of the furnace body 102. The front of the furnace body 102 contacts the surface of the furnace door 205. The auxiliary mechanism 3 includes a suction fan 301, and an air inlet 302 is fixedly connected to the right side of the suction fan 301. A filter plate 303 is clamped on the inner wall of the suction fan 301, and a handle 304 is provided on the top of the filter plate 303.

During this period, a large amount of smoke will be generated inside the furnace body 102. According to the principle that the airflow flows from high pressure to low pressure, a large amount of smoke flows into the concave smoking pipe 103 and then enters the exhaust pipe 104. The airflow movement is accelerated due to the height of the exhaust pipe 104, so that a large amount of smoke is quickly discharged. At the same time, the smoke passes through the filter 105 inside the exhaust pipe 104. The smoke is then discharged after filtration. At the same time, the upper smoke exhaust pipe 104 can be reinforced again at the screw hole on the top of the smoke exhaust pipe 104 according to the specific needs of the items. While the smoke exhaust pipe 104 is exhausting smoke, the control panel 202 is used to control the suction fan 301 to filter the indoor air through the filter plate 303 through the air inlet 302 and then transport it to the inside of the furnace body 102 for combustion assistance. Finally, the furnace door 205 under the inner wall of the main bracket 203 and the auxiliary bracket 206 is controlled to rise at the same time, and new items are fed in while pulling out items. After the work is completed, the filter plate 303 can be taken out by the handle for cleaning or replacement, and the filter 105 can be removed for cleaning or replacement by removing the bolts 106.
