[0048] In summary, the working principle of the present invention is as follows: air is introduced into the inner cavity of the purification box 1 through the air inlet pipe 4, and the anesthetic gas is discharged from the opening. The anesthetic gas can be filtered by setting the filter 76. During the anesthetic gas filtering process, if the amount of anesthetic gas passing through the filter 76 is too low, the signal is transmitted to the controller 2 under the action of the flow sensor 762. The controller 2 controls the power output shaft of the drive motor 73 to rotate. When the power output shaft of the drive motor 73 rotates, the worm A74 meshing with the drive motor 73 can rotate, and the circular ring can be driven by the cross bar. The disk 77 rotates, and the swing rod fixed on the disk 77 and the driving groove cooperate to make the vertical rod 79 rotate 90 degrees, so that the new filter 76 can be replaced, which is conducive to timely replacement of the filter 76, without the need for the staff to stop the operation, so as to avoid affecting the anesthesia effect of the patient. When the old filter 76 moves to a certain position, under the setting of the transparent glass 12, it is convenient for the staff to observe the inner cavity of the purification box 1, and then the servo motor 83 can be started through the controller 2. After the servo motor 83 outputs power, it rotates to make the servo motor 83 fixed on the servo motor 83 move. The worm B84 at the end of the power output shaft rotates, so that the worm wheel B85 meshing with the worm B84 can rotate, and then the threaded tube 86 can rotate. The threaded rod 87 threadedly connected in the inner cavity of the threaded tube 86 can make the rectangular plate 88 move upward under the limit of two adjacent limit telescopic rods A881, and then the magnetic block A89 fixed on the rectangular plate 88 and the adjacent drive motor 73 can move to the side away from each other under the action of magnetic force, so that the plurality of support rods 721 are located inside the filter frame 72. The filter screen 76 is located in the inner cavity of the collection tank 6, which is convenient for releasing the limit of the filter screen 76. When the adjacent movable plate 722 moves, the adjacent rack plate B93 can be moved downward with the cooperation of the pressing assembly 9. The push block 94 fixed on the rack plate B93 can push the filter screen 76 to move downward, thereby preventing the filter screen 76 from being stuck in the inner cavity of the filter frame 72 and affecting the efficiency of disassembly of the filter screen 76. The disassembled filter screen 76 is located in the inner cavity of the collection tank 6, which is convenient for the staff to concentrate on handling it. When handling the filter screen 76, the staff can install a new one on the adjacent filter frame 72.
