At this time, the nested plate can knock the second purification box through the knocking block, causing the second purification box to vibrate and accelerate the discharge of gas;

[0027] (4) When the nested disk moves up and down, it will drive the spring to undergo elastic deformation, and through the elastic force of the spring itself, drive the nested disk to reset. The spring and the magnetic block cooperate with each other, allowing the nested disk to move up and down reciprocatingly, further improving the vibration efficiency of the second purification box;

[0028] (5) When the auxiliary plate moves up and down, it will drive the adjustment rod to change its angle, and the adjustment rod can drive the adjustment disk to rotate. When the adjustment disk rotates, it will synchronously drive the linkage disk to rotate. At this time, the linkage disk can drive the linkage rod to change its angle. The linkage rod can pull the push rod, so that the push rod drives the exhaust baffle to move. At this time, the exhaust baffle does not block the exhaust groove, and the gas can be discharged outward through the exhaust groove. The exhaust baffle can block the exhaust groove, thereby improving the sealing of the device. BRIEF DESCRIPTION OF THE DRAWINGS
