[0025] Example:

[0026] Reference Figures 1-6This utility model provides a drinking water activated carbon filtration device, including a housing 1 and an activated carbon filter element 5. A cover 4 is provided on the top of the housing 1. The device also includes a connecting ring 6, fixedly connected to the top of the activated carbon filter element 5. A fixing ring 8 is fixedly connected to the bottom of the cover 4, and the connecting ring 6 is connected to the fixing ring 8. Two scrapers 202 are rotatably mounted below the cover 4 via a rotating shaft 201 and are arranged in a ring at equal intervals. The scrapers 202 are in contact with the inner surface of the activated carbon filter element 5. A driving part for driving the scrapers 202 to rotate is provided on the cover 4. The top of the cover 4 is fixedly connected to... A water pump 17 is provided, with an inlet pipe 19 and an outlet pipe 18 fixedly connected to its input and output ends, respectively. The inlet pipe 19 is used to connect to an external water source, and the outlet pipe 18 is connected to the inside of the housing 1. The outlet of the outlet pipe 18 is located inside the activated carbon filter element 5. A drain pipe 20 and a sewage pipe 21 are respectively provided on the side and bottom of the housing 1. The drain pipe 20 is used to discharge the filtered water, and the sewage pipe 21 is used to discharge the impurities cleaned from the activated carbon filter element 5. Valves are installed on both the drain pipe 20 and the sewage pipe 21. The opening and closing of the drain pipe 20 and the sewage pipe 21 are controlled by the valves to switch between drainage and sewage discharge.

[0027] During operation, by starting the water pump 17, the water to be filtered enters the activated carbon filter element 5 through the inlet pipe 19 and the outlet pipe 18. The water filtered by the activated carbon filter element 5 is discharged from the drain pipe 20. The drive unit drives the scraper 202 to rotate along the inner side of the activated carbon filter element 5, scraping off the impurities attached to the activated carbon filter element 5 and flushing the impurities away from the drain pipe 21. The activated carbon filter element 5 can be quickly disassembled for cleaning and replacement by setting the connecting ring 6 and the fixing ring 8, which improves the filtration efficiency.

[0028] The outer side of the connecting ring 6 is provided with an external thread 7, and the inner side of the fixing ring 8 is provided with an internal thread 9 that matches the external thread 7. The driving part includes a motor 203 fixedly connected to the top of the cover 4. Both the output end of the motor 203 and the rotating shaft 201 are fixedly connected with bevel gears 204, and the two bevel gears 204 are meshed together.

[0029] During operation, the motor 203 is started, and its output end drives the rotating shaft 201 to rotate through the transmission of the bevel gear 204. The rotating shaft 201 drives the scraper 202 to rotate. Through the design of the external thread 7 and the internal thread 9, the connecting ring 6 can be tightened or unscrewed from the fixing ring 8 for quick replacement of the activated carbon filter element 5.

[0030] A fixing block 10 is connected to the rotating shaft 201. An installation block 11 is fixedly connected to the side of the scraper 202 away from the activated carbon filter element 5. An installation groove 12 matching the installation block 11 is opened on the side of the fixing block 10 near the scraper 202. A sliding groove 13 is opened inside the fixing block 10. The sliding groove 13 communicates with the installation groove 12. A limiting block 14 is slidably installed inside the sliding groove 13. In the initial state, the limiting block 14 is in the sliding groove 13. A threaded rod 15 is threadedly connected to the fixing block 10. The threaded rod 15 is set vertically. One end of the threaded rod 15 extends out of the bottom of the fixing block 10 and a knob is fixedly connected to this end. The threaded rod 15 is rotatably connected to the limiting block 14 through a bearing. A limiting groove 16 matching the limiting block 14 is opened at the bottom of the installation block 11.

[0031] During operation, by rotating the threaded rod 15, the threaded rod 15 drives the limiting block 14 to slide into the slide groove 13 and pulls the limiting block 14 out of the limiting groove 16. Then, the scraper 202 is pulled outward to pull the mounting block 11 out of the mounting groove 12, so that the scraper 202 can be disassembled to clean the impurities on the scraper 202, or to replace the scraper 202 with a new one, so as to avoid the problem of poor cleaning effect caused by the wear of the scraper 202.

[0032] A guide block 302 is fixedly connected to the rotating shaft 201 via a connecting rod 301. A sliding groove 303 is provided on the side of the guide block 302 near the fixed block 10. A limiting rod 304 is fixedly connected between the inner walls of the sliding groove 303. A slider 305 is fixedly connected to the side of the fixed block 10 near the guide block 302. The slider 305 is slidably connected to the limiting rod 304. A spring 306 is installed between the bottom of the slider 305 and the inner wall of the sliding groove 303. A guide rod 307 is fixedly connected to the top of the fixed block 10. Both the guide rod 307 and the limiting rod 304 are vertically arranged. The upper end of the guide rod 307 is hemispherical. A protrusion 308 is fixedly connected to the bottom of the cover 4. The protrusion 308 is arranged on the movement path of the guide rod 307. The protrusion 308 is hemispherical. The number of protrusions 308 is 14-18, preferably 16. When the guide rod 307 contacts the protrusion 308, it will be squeezed by the protrusion 308.

[0033] During operation, when the drive scraper 202 rotates, the rotating shaft 201 drives the guide block 302 and the fixed block 10 to rotate synchronously via the connecting rod 301. The fixed block 10 drives the guide rod 307 to rotate synchronously. When the guide rod 307 contacts the protrusion 308, it is squeezed by the protrusion 308. The guide rod 307 drives the fixed block 10 to move downward. The fixed block 10 drives the slider 305 to slide downward along the limit rod 304 and compress the spring 306. When the guide rod 307 leaves the protrusion 308, the spring 306 returns to its original position, causing the fixed block 10 and the guide rod 307 to move upward. This causes the scraper 202 to shake up and down continuously while rotating, improving the effect of scraping off impurities.

[0034] In use, this activated carbon filtration equipment for drinking water is activated by starting the motor 203, which drives the rotating shaft 201 to rotate through the bevel gear 204. The rotating shaft 201 drives the scraper 202 to rotate, and the scraper 202 scrapes off the impurities attached to the activated carbon filter element 5 and flushes the impurities away from the drain pipe 21. Through the design of the external thread 7 and the internal thread 9, the connecting ring 6 can be tightened or unscrewed from the fixing ring 8 for quick replacement of the activated carbon filter element 5 for cleaning and replacement.

[0035] Meanwhile, the rotating shaft 201 drives the guide block 302 and the fixed block 10 to rotate synchronously through the connecting rod 301. The fixed block 10 drives the guide rod 307 to rotate synchronously. When the guide rod 307 contacts the protrusion 308, it is squeezed by the protrusion 308. The guide rod 307 drives the fixed block 10 to move downward. The fixed block 10 drives the slider 305 to slide downward along the limit rod 304 and compress the spring 306. When the guide rod 307 leaves the protrusion 308, the spring 306 returns to its original position, causing the fixed block 10 and the guide rod 307 to move upward. This causes the scraper 202 to shake up and down continuously while rotating, improving the effect of scraping off impurities.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
