[0026] like Figure 1-3As shown, the purification mechanism 4 includes a mounting shell 404, honeycomb activated carbon 410, and a lifting component 5. The front end of the main body 1 has a mounting groove 104 located above a water storage tank 103. A vent 105 connects the water storage tank 103 and the mounting groove 104. An exhaust pipe 6 connected to the upper end of the main body 1 and extending to the upper end of the mounting groove 104 is fixedly connected to the upper end of the main body 1. The mounting shell 404 is movably disposed within the mounting groove 104, with its upper end open. Several honeycomb activated carbons 410 are stacked within the mounting shell 404. The lifting component 5 is used to lift the honeycomb activated carbon within the mounting shell 404. Activated carbon 410 is used. An installation plate 401 is fixedly connected to the front end of the installation shell 404. Symmetrically distributed connecting plates 403 are fixedly connected to both sides of the installation plate 401. The connecting plates 403 are fixedly connected to both sides of the main body 1 by bolts. A handle 402 is fixedly connected to one side of the installation plate 401. A sealing ring 405 is fixedly connected to the other side of the installation plate 401 and fitted onto the installation shell 404. The gas dissolves soluble substances in the water in the water storage tank 103. Then, the gas is purified by adsorption of the honeycomb activated carbon 410 in the purification mechanism 4 after passing through the vent 105. The purified gas is discharged through the exhaust pipe 6.

[0027] like Figure 4-7As shown, the lifting assembly 5 includes an adjusting rod 501 and a lifting plate 508. The adjusting rod 501 is horizontally rotatably connected to the mounting plate 401. One end of the adjusting rod 501 is fixedly connected to a turntable 502. A limiting ring 504 is fixedly connected to the inner side of the turntable 502. An annular groove 409 is opened at the front end of the mounting plate 401, and the limiting ring 504 is rotatably connected to the annular groove 409. A rocker handle 503 is fixedly connected to the outer side of the turntable 502. The other end of the adjusting rod 501 is fixedly connected to a first bevel gear 5. 05, the first bevel gear 505 meshes with the second bevel gear 506, the lower end of the second bevel gear 506 is fixedly connected to a vertically arranged screw 507, the lifting plate 508 is vertically slidably disposed in the mounting housing 404, one end of the lifting plate 508 is fixedly connected to a slider 509 threadedly connected to the screw 507, the mounting housing 404 is provided with a toothed groove 406, the first bevel gear 505 and the second bevel gear 506 are both rotatably disposed in the toothed groove 406, and one side of the inner wall of the mounting housing 404 is provided with a A vertically distributed sliding groove 407 is provided. The screw 507 is vertically rotatably connected to the sliding groove 407, and the slider 509 is slidably engaged within the sliding groove 407. A symmetrically distributed limiting groove 408 is provided on the other side of the inner wall of the mounting shell 404. A symmetrically distributed limiting block 510 is fixed to the other end of the lifting plate 508. The limiting block 510 is vertically slidably connected within the limiting groove 408. By rotating the rocker handle 503, the lifting plate 508 is driven to rise vertically within the mounting shell 404, thereby raising the mounting shell 404. The honeycomb activated carbon 410 is raised for easy replacement. The sliding of the slider 509 in the slide groove 407 and the sliding of the limiting block 510 in the limiting groove 408 improve the stability of the vertical movement of the lifting plate 508. The lower end of the mounting shell 404 and the lifting plate 508 are provided with several overlapping through holes 7, so that the gas in the water storage tank 103 can pass through the air vent 105 and the through holes 7 on the lower end of the mounting shell 404 and the lifting plate 508 to enter the honeycomb activated carbon 410 for adsorption and purification.

[0028] In use, this utility model uses a water supply pipe 3 to input clean water into a water storage tank 103, and a transparent observation plate 102 to control the water volume in the water storage tank 103. A fan is used to introduce gas into the water from the air inlet pipe 2, so that the soluble substances in the gas dissolve. Then the gas enters the mounting groove 104 through the air vent 105, and then enters the mounting shell 404 through the through holes 7 on the mounting shell 404 and the lifting plate 508. The honeycomb activated carbon 410 in the mounting shell 404 then adsorbs and purifies the gas. The purified gas is then discharged from the exhaust pipe 6.

[0029] When the honeycomb activated carbon 410 needs to be replaced, the purification mechanism 4 is disassembled from the main body 1 using bolts, and then pulled out of the mounting slot 104 using handle 402. The crank handle 503 is turned to drive the turntable 502 to rotate. The limiting ring 504 rotates in the annular groove 409 to improve the rotational stability of the turntable 502. The turntable 502 drives the adjusting rod 501 to rotate, which in turn drives the first bevel gear 505 to rotate, which in turn drives the second bevel gear 506 to rotate, which in turn drives the screw 507 to rotate. This causes the slider 509 to slide vertically upward in the sliding groove 407, which in turn causes the lifting plate 508 to rise vertically in the mounting shell 404. At the same time, the limiting block 510 slides in the limiting groove 408 to improve the stability of the rising of the lifting plate 508. The rising of the lifting plate 508 lifts the honeycomb activated carbon 410 in the mounting slot 104, making it easier to remove the honeycomb activated carbon 410 in the mounting slot 104 for replacement.
