[0015] See also Figures 1-2 In an embodiment of the utility model, a quickly replaceable activated carbon filter comprises a filter box 1, the filter box 1 is in the shape of a box, a support frame 2 is fixedly connected to the bottom of the filter box 1, an air inlet 3 and an air outlet 4 are respectively opened at both ends of the filter box 1, and the air inlet 3 and the air outlet 4 respectively connect the inside of the filter box 1 with the external environment, an activated carbon partition 5 is arranged inside the filter box 1, one side of the activated carbon partition 5 passes through the side wall of the filter box 1 and extends to the outside of the filter box 1, and a quick-release structure is arranged on the side of the activated carbon partition 5 extending to the outside of the filter box 1.

[0016] Preferably, the quick-release structure includes a connecting plate 6, which is fixedly connected to the side of the activated carbon partition 5, and the width and length of the connecting plate 6 are both larger than the width and length of the through hole of the activated carbon partition 5 passing through the side wall of the filter box 1. When the screw 11 abuts against the surface of the connecting plate 6, the sealing strip 7 can seal the through hole to prevent exhaust gas from leaking from the gap between the connecting plate 6 and the filter box 1. A fixing pin 8 is fixedly connected to the outer surface of the filter box 1, and a rotating rod 10 is rotatably connected to the surface of the fixing pin 8. The internal thread of the rotating rod 10 is connected to a screw 11, and the bottom end of the screw 11 abuts against the surface of the connecting plate 6 away from the filter box 1.

[0017] Preferably, a sealing strip 7 is fixedly connected to the surface of the connecting plate 6 close to the filter housing 1 to perform sealing to prevent exhaust gas leakage.

[0018] Preferably, each connecting plate 6 is provided with two screws 11 against its surface, and the two screws 11 are respectively located on the upper and lower sides of the connecting plate 6, and the connecting plate 6 is respectively pressed from the upper and lower ends, so that the connecting plate 6 is closer to the surface of the filter box 1, and the sealing strip 7 is compressed to prevent exhaust gas leakage inside the filter box 1.
