[0026] Specifically, first start the fan 22, the fan 22 will pull the exhaust gas from the intake pipe 2 into the first treatment box 1, and then pass through the filter 13, the filter 13 will filter out the graphite dust and other particles attached to the exhaust gas, and the graphite dust will remain on the filter 13, start the motor 7, the motor 7 drives the rotating shaft 8 to rotate, thereby driving the eccentric wheel 9 to rotate, and then drives the upper end of the rotating rod 10 to rotate along with the eccentric part of the eccentric wheel 9, and the lower end of the rotating rod 10 drives the connecting rod 11 to move up and down, and the connecting rod 11 drives the scraper 12 to move up and down to clean the graphite dust on the filter 13, so that the graphite dust falls into the dust collecting frame 14 below, and later it only needs to be taken out of the dust collecting frame 14 for cleaning.

[0027] Reference Figure 1 and Figure 3 , Figure 4The right end of the first processing box 1 is fixedly connected to a connecting pipe 3, and the right end of the connecting pipe 3 is fixedly connected to a second processing box 4. The opposite end of the control rod 18 is fixedly connected to a spring 20, and the opposite ends of the spring 20 are respectively fixedly connected to the front and rear ends of the inner wall of the second processing box 4. The opposite end of the control rod 18 is fixedly connected to a card block 19, and the card block 19 is consistent with the shape of the card groove of the front and rear inner walls of the adsorption plate 21. A pressure groove is provided on the outer wall of the control rod 18, and buttons 15 are slidably connected to the front and rear sides of the inner wall of the top of the second processing box 4. The bottom end of the button 15 is fixedly connected to an extrusion block 16, and the extrusion block 16 is located above the pressure groove.

[0028] Specifically, the exhaust gas passing through the filter 13 will carry the remaining harmful gas into the second treatment box 4 from the connecting pipe 3, and the adsorption plate 21 in the second treatment box 4 will adsorb the harmful gas. The adsorption plate 21 can make the activated carbon, and the harmless exhaust gas after treatment is discharged from the outlet pipe 5. The adsorption plate 21 will gradually become saturated after being used for a period of time and can no longer effectively adsorb harmful gases. At this time, you only need to press the button 15, and the button 15 will drive the extrusion block 16 to move downward into the pressure groove in the control rod 18. Because the lower end of the extrusion block 16 is triangular, the control rod 18 moves outward when the extrusion block 16 enters the pressure groove, thereby driving the card block 19 to leave the card slot in the adsorption plate 21. Finally, you can use the handle at the top of the adsorption plate 21 to remove the adsorption plate 21 for replacement.

[0029] Working principle: When in use, start the fan 22, the exhaust gas will enter the first treatment box 1 from the air inlet pipe 2, and then pass through the filter 13, the filter 13 will filter out the graphite dust and other particles attached to the exhaust gas, start the motor 7, the motor 7 drives the shaft 8 to rotate, thereby driving the eccentric wheel 9 to rotate, and then drives the upper end of the rotating rod 10 to rotate along with the eccentric part of the eccentric wheel 9, thereby driving the connecting rod 11 to move up and down, and the connecting rod 11 drives the scraper 12 to move up and down to hang the graphite dust on the filter 13, so that the graphite dust falls into the dust collecting frame 14 below, and at the same time The exhaust gas passing through the filter 13 will carry the remaining harmful gas into the second treatment box 4 from the connecting pipe 3. The adsorption plate 21 in the second treatment box 4 will adsorb the harmful gas and discharge the treated harmless exhaust gas from the outlet pipe 5. The adsorption plate 21 will gradually become saturated after being used for a period of time and can no longer effectively adsorb the harmful gas. At this time, you only need to press the button 15. The button 15 drives the extrusion block 16 to enter the pressure groove in the control rod 18, so that the control rod 18 moves outward, thereby driving the card block 19 to leave the card groove in the adsorption plate 21. Finally, the adsorption plate 21 can be removed for replacement.
