When the filter layer 14 needs to be replaced through long-term use, the operator pulls the clamping column 18 out of the clamping hole 15, and then the filter layer 14 is replaced and then the clamping column 18 is clamped in the clamping hole 15 again, so that the operation is simple and convenient, and the operator can replace the filter layer 14 conveniently.

The method comprises the following operation steps: under normal state, the baffle 6 blocks the smoke outlet 5 of the smoke exhaust machine 3. When a fire disaster happens, the smoke sensor 8 sends a signal to the controller 9 after detecting smoke, and the controller 9 controls the cylinder 7 and the smoke exhaust fan 3 to work. At this point the output end of the cylinder 7 is retracted so that the shutter 6 is removed from the smoke outlet 5 of the extractor 3. The smoke exhaust machine 3 is operated to exhaust smoke from the room, and the smoke passes through the smoke inlet 4, is adsorbed and filtered by the filter layer 14, and then is exhausted from the smoke outlet 5. After finishing discharging fume, the smoke sensor 8 can not detect smoke and send a signal to the controller 9, the controller 9 controls the smoke exhaust machine 3 to stop working, the output end of the cylinder 7 stretches out to drive the baffle 6 to move along the vertical direction of the guide rail 10, so that the baffle 6 blocks the smoke exhaust port 5, one end of the baffle 6 far away from the cylinder 7 is abutted against the first limiting plate 12, and the second limiting plate 13 is abutted against one end of the guide rail 10 far away from the first limiting plate 12.
