[0027] A gas collecting mechanism 2 is installed on one side of the top of the bottom plate 1, an adsorption mechanism 3 is installed on the top of the gas collecting mechanism 2, and the adsorption mechanism 3 is located on one side of the gas collecting mechanism 2 and the top of the bottom plate 1, a filtering mechanism 4 is installed on one side of the adsorption mechanism 3, and the filtering mechanism 4 is located on the top of the bottom plate 1;

[0029] The gas collecting mechanism 2 comprises:

[0030] The air collecting box 201 is installed at the top of the bottom plate 1. The upper and lower ends of the inner side of the air collecting box 201 are provided with slide grooves 202. The air collecting pipe 214 is installed at one end of the air collecting box 201. The motor 203 is installed inside the other end of the air collecting box 201. The output end of the motor 203 is connected to the screw rod 204. The two ends of the screw rod 204 are symmetrically installed with mounting plates 206. The outer wall of the screw rod 204 is installed with a movable sleeve 205. The other end of the movable sleeve 205 is installed with a sliding rod 215. The two ends of the sliding rod 215 are symmetrically installed with fixed sleeves 207. One end of the movable sleeve 205 is installed with a clamping plate 209.
