An electric scraping type self-cleaning filter according to claim 8, characterized in that: the outer walls of the base plate (22) are provided with integrated connecting rods (33), and the integrated connecting rods The two ends of (33) are welded to the outer wall of the base plate (22) and the inner wall of the stainless steel carrier (1) respectively. 10. The cleaning method of a kind of electric scraping type self-cleaning filter according to claim 9, is characterized in that, comprises the following steps: Step 1: Inject the water to be filtered through the water injection sleeve (11), the water injection pipe is sealed and connected to the flange groove (35), and the water is first filtered through the coarse filter screen (36), and then passed through the diversion The pipeline (10) enters the interior of the stainless steel carrier (1); Step 2: Water enters the stainless steel carrier (1) and then flows into the fine water filter mesh (23) of the ring-shaped cylindrical structure, passes through the secondary filtration of the fine water filter mesh (23), and then discharges to the surroundings, and finally discharges sewage through drainage The outlet is discharged to obtain filtered water; Step 3: Large particles of impurities in the water remain on the upper end of the coarse water filter (36), and the impurities filtered from the upper end of the coarse water filter (36) are cleaned and discharged by unscrewing the water injection sleeve (11), and then Operate the filter for self-cleaning; Step 4: During self-cleaning, turn on the drive motor (9), and by driving 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 decontamination The scraping roller (26) scrapes off the remaining impurities on the inner wall of the fine water filter (23), and the driven gear ring (20) drives the entire cylindrical fine water filter (23) to rotate counterclockwise, assisting the decontamination and scraping. Roller (26) carries out the scraping operation of impurity; Step 5: After the impurities are scraped off, they fall to the upper end of the base plate (22), then turn off the drive motor (9), and push the stainless steel sleeve (28) to the position where it is socketed with the fine water filter screen (23) , close the mesh above the driven toothed ring (20), and then inject a sufficient amount of clear water into the fine water filter (23), and the clean water is sealed in the fine water filter (23) by the stainless steel sleeve (28). Inside, the internal gravitational pressure of the water filter fine mesh (23) is increased, and the filling round seat (30) inside the impact base plate (22) is impacted; Step 6: After the gravity is increased to be greater than the reset force of the return spring (32), the gravity of the falling water will wash away the filling round seat (30), so that the scraped impurities are washed out together with the clean water, and pass through the drain outlet (3 ) Discharge impurities and clean water. In order to maintain the gravity of water during the sewage discharge process, it is necessary to continuously inject clean water until the impurities are completely discharged; Step 7: Put the water injection sleeve (11) back on one end of the diversion pipe (10), then pull up the stainless steel sleeve (28) with tweezers, and reconnect with the diversion pipe (10) with magnetic suction .
