[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 The present invention provides a collection device for treating waste gas, comprising a collection body 1 and a connecting hose 2.

[0027] Reference Figure 1 - Figure 3 As shown, a connecting hose 2 is installed on one side of the collecting body 1, and a filter structure 3 is provided on one side of the connecting hose 2. The filter structure 3 includes a connector 301 located on one side of the connecting hose 2. A groove 302 is formed inside the connector 301, and a top plate 303 is provided inside the groove 302. Return springs 304 are evenly fixed on one side of the top plate 303. A positioning groove 305 is formed on the inner wall of the connecting hose 2 on one side of the connector 301, and a filter plate 30 is provided inside the connector 301. 6. Protrusions 307 are evenly fixed on the outer wall of the filter plate 306. The top plate 303 is slidably connected inside the slide groove 302. The return springs 304 are evenly distributed on one side of the top plate 303. The positioning grooves 305 are symmetrically distributed on the inner wall of the connecting hose 2 on one side of the connector 301. The filter plate 306 is slidably connected inside the connector 301. The protrusions 307 are set inside the positioning grooves 305. The filter plate 306 and the positioning grooves 305 form a locking structure through the protrusions 307.

[0028] In the process of treating waste gas, it is necessary to collect and analyze the data in advance to provide a treatment plan. This involves providing a filter structure 3, which pushes the filter plate 306 and protrusion 307 into the sliding groove 302. Rotating the filter plate 306 causes the protrusion 307 to rotate to one side of the positioning groove 305, after which the filter plate 306 is released. The return spring 304 provides thrust to the top plate 303, which in turn pushes the filter plate 306, causing the protrusion 307 on the outer wall of the filter plate 306 to move into the positioning groove 305. This prevents the filter plate 306 from shifting position within the connector 301. If significant contamination occurs on the surface of the filter plate 306, further pushing the filter plate 306 away from the positioning groove 305 and then rotating it allows the protrusion 307 to pull the filter plate 306 out through one side of the sliding groove 302. This allows for disassembly, cleaning, and replacement of the filter plate 306, greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the bottom of the collecting body 1 is provided with a disassembly and assembly structure 4. The disassembly and assembly structure 4 includes an installation groove 401 at the bottom of the collecting body 1. A collecting bottle 402 is provided inside the installation groove 401. A snap-fit ​​groove 403 is evenly provided on the top of the collecting bottle 402. An internal groove 404 is provided inside the collecting body 1 outside the installation groove 401. An inclined block 405 is provided inside the internal groove 404. A positioning spring 406 is fixed on one side of the inclined block 405. The collecting bottle 402 is slidably connected inside the installation groove 401. The snap-fit ​​grooves 403 are symmetrically distributed on the top of the collecting bottle 402. The inclined block 405 is provided inside the snap-fit ​​groove 403. The inclined block 405 and the collecting bottle 402 form a snap-fit ​​structure through the snap-fit ​​groove 403.

[0030] The collection bottle 402 is used to collect the absorbed waste gas. In order to facilitate its installation on one side of the collection body 1, a disassembly and assembly structure 4 is provided. The top of the collection bottle 402 is pushed into the installation groove 401, which facilitates the squeezing of the inclined block 405 into the inner groove 404. The inclined block 405 is affected by the pushing force of the positioning spring 406 inside the inner groove 404. When the snap-fit ​​groove 403 opened on the top of the collection bottle 402 moves to one side of the inclined block 405, the inclined block 405 moves into the snap-fit ​​groove 403 due to the pushing force, thus positioning the collection bottle 402. When the collection bottle 402 needs to be removed, the collection bottle 402 is pushed further to push the inclined block 405 into the inner groove 404. Then the collection bottle 402 is rotated and pulled out, so that the snap-fit ​​groove 403 does not easily move to one side of the inclined block 405 during the extraction process, thus facilitating the disassembly and assembly of the collection bottle 402 and greatly increasing the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
