[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a formaldehyde removal purifier supported on graphene, comprising a purifier body 1, an air outlet pipe at the lower end of the purifier body 1, and a plurality of matrix-distributed air inlet holes 2 at the top end of the purifier body 1. A funnel-shaped air guide funnel 3 is located at the upper end of the purifier body 1, and an air outlet circular pipe 4 is located at the bottom end of the air guide funnel 3. The air guide funnel 3 and the air outlet circular pipe 4 are designed with a top-bottom circular shape. A formaldehyde removal component 5 is connected to the bottom end of the air outlet circular pipe 4. The formaldehyde removal component 5 includes components disposed on the air outlet circular pipe 4. The formaldehyde removal box 501 has a rectangular bottom end. The top of the formaldehyde removal box 501 has an air inlet connected to the exhaust pipe 4. Inside the formaldehyde removal box 501 is a filter screen 502. At the bottom of the formaldehyde removal box 501 is a graphene plate 503. On one side of the formaldehyde removal box 501 is a first discharge port 504 flush with the filter screen 502. Outside the formaldehyde removal box 501 is a waste collection box 505. At the upper end of the waste collection box 505 is a second discharge port corresponding to the first discharge port 504. The formaldehyde removal box 501 is equipped with a scraping assembly 507 for scraping and conveying the filter material into the waste collection box 505. The purifier body 1 can be installed on an AGV trolley, which can move the purifier to quickly purify formaldehyde in various locations in the room. The formaldehyde removal assembly 5 effectively purifies formaldehyde in the room air, preventing it from harming human health. The graphene plate 503 adsorbs and purifies formaldehyde in the air, reducing its concentration. The formaldehyde content in the air is reduced. A filter plate 502 is provided at the air inlet of the graphene plate 503 to filter large particles in the air, avoiding the blockage of the graphene plate 503 by large particles and affecting the purification effect of the graphene plate 503. The filtered large particles can be pushed into the interior of the waste collection box 505 through the scraping action of the scraping component 507 through the first discharge port 504 and the second discharge port 506, avoiding the blockage of the filter material adsorbed on the filter plate 502 and affecting the normal filtration effect.

[0027] The first discharge port 504 and the second discharge port 506 are the same size. A matching cover 508 is connected to the second discharge port 506 via a rotating shaft. A torsion spring is provided on the rotating shaft of the cover 508. A limiting stop 509 is provided at the top of the first discharge port 504. The scraping assembly 507 includes an electric push rod 5010 installed on the upper end of the formaldehyde removal box 501. The output shaft of the electric push rod 5010 is connected to the filter. When the scraper 5011, which abuts against the screen plate 502, scrapes the filter material on the screen plate 502, the output shaft of the electric push rod 5010 pushes the scraper 5011 to move. The scraper 5011 scrapes and cleans the large particles adhering to the screen plate 502, avoiding the large particles from clogging the screen plate 502. When the scraper 5011 moves to the second discharge port 506, it pushes open the cover 508, which pushes the filter material into the interior of the waste collection box 505.

[0028] The purifier body 1 has a stepped opening at its top, and a cover plate 6 is provided at the stepped opening. The air inlet 2 is opened on the cover plate 6. Both sides of the cover plate 6 are provided with claw ears 7. The stepped opening of the purifier body 1 is provided with an elastic protrusion 8. The inner wall of the cover plate 6 is provided with a groove that matches the elastic protrusion 8. The cover plate 6 can be opened to clean the filter and replace the graphene plate 503. When the cover plate 6 is placed on the top of the purifier body 1, the elastic protrusion 8 matches the groove. When opening, the claw ears 7 are lifted upwards to separate the elastic protrusion 8 from the groove, so that the cover plate 6 can be opened.

[0029] The air funnel 3 has a receiving ring 9 at its top end, and the inner wall of the purifier body 1 has a support ring 10 that supports the receiving ring 9. The inner wall of the air funnel 3 has a handle 11. The receiving ring 9 and the support ring 10 are connected by bolts. The support ring 10 can limit the support ring 9. The support ring 10 and the receiving ring 9 are fixed by screws to improve stability and facilitate disassembly and assembly.

[0030] The formaldehyde removal box 501 has a connecting sleeve 12 at its air inlet that is threaded to the air outlet pipe 4. The outer wall of the connecting sleeve 12 is provided with a positioning slide 13, and a positioning collar 14 is fitted on the outside of the connecting sleeve 12. The inner wall of the positioning collar 14 is provided with a positioning groove 15 that matches the positioning slide 13. The outer wall of the connecting sleeve 12 is provided with a limiting support ring 16. The connecting sleeve 12 and the air outlet pipe 4 can be disassembled and assembled. The positioning slide 13 can be quickly positioned via the positioning groove 15 on the positioning collar 14, and the limiting support ring 16 can provide limiting support for the connecting sleeve 12. This allows for quick positioning of the waste collection box 505, so that the first discharge port 504 and the second discharge port 506 correspond to each other, making it easy to disassemble and replace.

[0031] The waste collection box 505 has two support plates 17 at its bottom. The support plate 17 near the second discharge port 506 has a notch 18. The outer wall of the formaldehyde removal box 501 has a locking screw 19 that matches the notch 18. The locking screw 19 has a locking nut 20. The waste collection box 505 has a sealing washer 21 around the second discharge port 506. The locking nut 20 and the locking screw 19 can be used to fix the support plate 17. With the sealing washer 21, the sealing performance of the connection between the waste collection box 505 and the formaldehyde removal box 501 is improved.

[0032] The waste collection box 505 has a positioning ring 22 on the inner wall of its lower end. The waste collection box 505 has mounting grooves 23 on both opposite sides. Multiple return springs 24 are installed in the mounting grooves 23. A limiting plate 25 connected to the return springs 24 and extending out of the mounting grooves 23 is installed in the mounting grooves 23. Pushing the limiting plate 25 compresses the return springs 24. When the limiting plate 25 enters the mounting grooves 23, the graphene plate 503 can be disassembled and replaced, which facilitates the disassembly and replacement of the graphene plate 503.

[0033] During operation, this graphene-loaded formaldehyde purifier, through its formaldehyde removal component 5, can purify the formaldehyde in the room air, preventing it from harming human health. The graphene plate 503 adsorbs and purifies the formaldehyde in the air, reducing its concentration. A filter plate 502 is located at the air inlet of the graphene plate 503 to filter large particles, preventing them from clogging the plate and affecting its purification effect. The filtered large particles are then pushed into the waste collection box 505 through the first discharge port 504 and the second discharge port 506 by the scraping action of the scraping component 507, preventing the filter material adsorbed on the filter plate 502 from clogging and affecting the normal filtration effect.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
