[0021] Preferably, the cleaning method of the electric scraping self-cleaning filter comprises the following steps:

[0022] Step 1: Inject the water to be filtered through the water injection sleeve. The water injection pipe is sealed and connected to the flange groove. After the water passes through the coarse water filter mesh for the first filtration, it enters the interior of the stainless steel carrier through the diversion pipe;

[0023] Step 2: After entering the stainless steel carrier tube, the water flows into the water filter mesh of the annular cylindrical structure, is filtered twice by the water filter mesh, and is discharged to the surrounding areas, and finally discharged through the drainage outlet to obtain filtered water;

[0024] Step 3: Large particles of impurities in the water remain on the upper end of the coarse water filter. Remove the water injection sleeve, clean and drain the impurities filtered out of the upper end of the coarse water filter, and then operate the filter to perform self-cleaning.

[0025] Step 4: During self-cleaning, the drive motor is turned on to rotate the bearing shaft and the driven gear ring. The bearing shaft drives the transmission blade to rotate clockwise, so that the dirt removal scraper roller scrapes off the impurities remaining on the inner wall of the water filter mesh. The driven gear ring drives the entire cylindrical water filter mesh to rotate counterclockwise, assisting the dirt removal scraper roller in scraping off the impurities.

[0026] Step 5: After the impurities are scraped off, they fall to the upper end of the base plate. Then, the drive motor is turned off and the stainless steel sleeve is pushed to the position where it is connected to the water filter mesh, closing the mesh holes above the driven gear ring. Then, sufficient clean water is injected into the water filter mesh. The clean water is sealed inside the water filter mesh by the stainless steel sleeve, which increases the internal gravity pressure of the water filter mesh and impacts the filling round seat inside the base plate.

[0027] Step 6: When the gravity increases to a level greater than the reset force of the reset spring, the gravity of the falling water will flush the filling round seat open, so that the scraped impurities are flushed out together with the clean water, and the impurities and clean water are discharged through the drainage outlet. In order to maintain the gravity of the water during the drainage process, it is necessary to continuously inject clean water until the impurities are completely discharged;

[0028] Steps: Install the water injection sleeve back to one end of the diversion pipe, then use tweezers to pull up the stainless steel sleeve and reconnect it to the diversion pipe by magnetic attraction.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention scrapes off the impurities remaining on the inner wall of the water filter mesh through the dirt removal scraper roller, and the driven gear ring drives the entire cylindrical water filter mesh to rotate counterclockwise, assisting the dirt removal scraper roller to scrape off the impurities, thereby improving the self-cleaning effect of scraping stains, and discharging impurities and clean water through the drainage outlet. In order to maintain the gravity of the water during the sewage discharge process, it is necessary to continuously inject clean water until the impurities are completely discharged. This overcomes the problems of the existing filtering self-cleaning device having poor self-cleaning power during use and the easy occurrence of blockage inside the device during operation.

[0031] 2. Push the stainless steel sleeve to the position where it is socketed with the water filter mesh, close the mesh holes above the driven gear ring, and then inject enough clean water into the water filter mesh. The clean water is sealed inside the water filter mesh by the stainless steel sleeve, which increases the internal gravity pressure of the water filter mesh and impacts the filling round seat inside the base plate. When the gravity increases to a level greater than the reset force of the reset spring, the gravity of the falling water will flush the filling round seat open, so that the scraped impurities are connected to the clean water and flushed out together, achieving the purpose of all-round immersion impact discharge.

[0055] See also Figure 1-6 A method for cleaning an electric scraping self-cleaning filter comprises the following steps:

[0056] Step 1: The water to be filtered is injected through the water injection sleeve 11. The water injection pipe is sealed with the flange connection groove 35. After the water passes through the coarse water filter 36 for the first filtration, it enters the interior of the stainless steel carrier tube 1 through the diversion pipe 10;

[0057] Step 2: After entering the stainless steel carrier tube 1, the water flows into the water filter mesh 23 of the annular cylindrical structure, is filtered twice by the water filter mesh 23, and is discharged to the surrounding areas, and finally discharged through the drainage outlet to obtain filtered water;

[0058] Step 3: Large particles of impurities in the water remain on the upper end of the coarse water filter 36. Remove the water injection sleeve 11 and clean the impurities filtered from the upper end of the coarse water filter 36. Then operate the filter to perform self-cleaning.

[0059] Step 4: During self-cleaning, the drive motor 9 is turned on to rotate the bearing shaft 24 and the driven gear ring 20. The bearing shaft 24 drives the transmission blade 25 to rotate clockwise, so that the dirt removal scraper roller 26 scrapes off the impurities remaining on the inner wall of the water filter mesh 23. The driven gear ring 20 drives the entire cylindrical water filter mesh 23 to rotate counterclockwise, assisting the dirt removal scraper roller 26 in scraping off the impurities.

[0060] Step 5: After the impurities are scraped off, they fall to the upper end of the base plate 22. Then, the drive motor 9 is turned off, and the stainless steel sleeve 28 is pushed to the position where it is connected to the water filter mesh 23, closing the mesh holes above the driven gear ring 20. Then, a sufficient amount of clean water is first injected into the water filter mesh 23. The clean water is sealed inside the water filter mesh 23 by the stainless steel sleeve 28, causing the internal gravity pressure of the water filter mesh 23 to increase, impacting the filling round seat 30 inside the base plate 22.

[0061] Step 6: After the gravity increases to a value greater than the reset force of the reset spring 32, the gravity of the falling water will open the filling round seat 30, so that the scraped impurities are flushed out together with the clean water, and the impurities and clean water are discharged through the drainage outlet 3. In order to maintain the gravity of the water during the drainage process, it is necessary to continuously inject clean water until the impurities are completely discharged.

[0062] Step 7: Install the water injection sleeve 11 back to one end of the diversion pipe 10, then use tweezers to pull up the stainless steel sleeve 28 and reconnect it to the diversion pipe 10 by magnetic attraction.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.

The water injection sleeve (11) is unscrewed and disassembled, and the impurities filtered from the upper end of the coarse water filter screen (36) are cleaned and discharged, and then the filter is operated to perform self-cleaning; Step 4: During self-cleaning, the driving motor (9) is turned on to drive the bearing shaft (24) and the driven gear ring (20) to rotate. The bearing shaft (24) drives the transmission blade (25) to rotate clockwise, so that the dirt removal scraper roller (26) scrapes off the impurities remaining on the inner wall of the water filter mesh (23). The driven gear ring (20) drives the entire cylindrical water filter mesh (23) to rotate counterclockwise, assisting the dirt removal scraper roller (26) in scraping off the impurities. Step 5: After the impurities are scraped off, they fall onto the upper end of the base plate (22), and then the drive motor (9) is turned off, and the stainless steel sleeve tube (28) is pushed to the position where it is sleeved with the water filter mesh (23), closing the mesh holes above the driven gear ring (20), and then a sufficient amount of clean water is injected into the water filter mesh (23). The clean water is sealed inside the water filter mesh (23) by the stainless steel sleeve tube (28), so that the internal gravity pressure of the water filter mesh (23) increases, impacting the filling round seat (30) inside the base plate (22); Step 6: After the gravity increases to a value greater than the reset force of the reset spring (32), the gravity of the falling water will flush the filling round seat (30), so that the scraped impurities are connected to the clean water and flushed out together, and the impurities and clean water are discharged through the drainage outlet (3). In order to maintain the gravity of the water during the drainage process, it is necessary to continuously inject clean water until the impurities are completely discharged; Step 7: Install the water injection sleeve (11) back to one end of the diversion pipe (10), then use tweezers to pull up the stainless steel sleeve (28) and reconnect it to the diversion pipe (10) by magnetic attraction.
