[0034] Working principle: When the device is in use, a mixture of cleaning water and oil stain cleaner needs to be injected into the water tank 10 through the water injection pipe 23. Then, the oil fume to be purified is connected to the air inlet pipe 2. The oil fume is filtered and purified by the first-stage filter plate 3 in the purification box 1. The purified oil fume is discharged through the heat exchange tube 20 in the water tank 10 at the top of the purification box 1 to complete the purification. The heat in the oil fume in the heat exchange tube 20 heats the cleaning water and raises its temperature.

[0035] When cleaning is required after each use, first start the drive motor 9. The output end of the drive motor 9 drives the first-stage threaded rod 8 to rotate. The first-stage threaded rod 8 drives the first-stage moving block 4 to move. The first-stage moving block 4 drives the cleaning brush 5 to move and clean the first-stage filter plate 3. While the cleaning brush 5 is moving, the gear 7 installed at its other end works with the rack 6 to make the cleaning brush 5 rotate, so that it scrapes and cleans during the rolling process, improving the cleaning effect.

[0036] When the cleaning brush 5 is cleaning, the electronic valve 21 is turned on. The electronic valve 21 delivers water from the water tank 10 to the diversion pipe 13 through the hose 22 and sprays it out to the upper side of the primary filter plate 3 through the nozzle 14. The primary threaded rod 8 drives the drive wheel 15 to rotate. The drive wheel 15 drives the transmission wheel 16 to rotate through the transmission belt 19. The transmission wheel 16 drives the secondary threaded rod 11 to rotate. The secondary threaded rod 11 drives the secondary moving block 12 to move. The secondary moving block 12 drives the diversion pipe 13 to move. The diversion pipe 13 drives the nozzle 14 to move, so that the cleaning water in the nozzle 14 is evenly sprayed onto the upper side of the primary filter plate 3. The cleaning water with a certain temperature can quickly soften the oil on the primary filter plate 3, making it easier for the cleaning brush 5 to scrub it and further improve its cleaning effect.

[0037] After cleaning is complete, manually open the drain pipe 17 to drain the oil and liquid mixture at the bottom of the purification tank 1, thus completing the cleaning process.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
