The paddle 21 is fixedly arranged on the paddle fixing seat at the other end of the power transmission shaft 20, and a plurality of the paddles 21 are evenly distributed around the paddle fixing seat. When the liquid in the filter barrel 12 flows upward into the connecting port, it will push the paddle 21 to rotate, thereby driving the power transmission shaft 20 to rotate, and providing rotational power for the sun gear 17.

[0050] The scraping cleaning member includes an external scraping and clearing member and an internal water flow flushing member, and both the external scraping and clearing member and the internal water flow flushing member are arranged on the deceleration support member. The external scraping and clearing member includes an external scraping and clearing transmission member and an external scraping member, and the external scraping and clearing transmission member is arranged on the deceleration support member, and the external scraping member is arranged on the external scraping and clearing transmission member.

Furthermore, the overall direction of the scraping guide accommodating groove 24 is in the shape of a spiral groove, and the cross-section of the scraping guide accommodating groove 24 is in the shape of a rectangular groove. At the same time, the groove wall height on one side of the scraping guide accommodating groove 24 is smaller than the groove wall height on the other side, so as to facilitate the installation of the scraping blade 25 and improve the flushing efficiency of the internal water flow flushing member. If a specification is required, the parameters of the spiral shape of the scraping guide accommodating groove 24 are the same as the parameters of the spiral shape of the scraping transmission second rod 23.

[0053] The scraper blade 25 is installed on the side wall of the scraper guide groove 24 through the scraper transmission plate 26, so that the scraper blade 25 and the top of the side wall of the scraper guide groove 24 are spaced apart, and the spacing is not less than the diameter of the filter hole, and the inner side of the scraper blade 25 is in contact with the outer side of the filter barrel 12, so as to improve the efficiency of chopping and scraping impurities plugged into the filter hole, and improve the efficiency of the internal water flow flushing member flushing the residual impurities in the filter hole outward. A plurality of the scraper transmission plates 26 are evenly spaced along the axial direction of the filter barrel 12 to improve the force stability of the scraper blade 25.

[0054] In case of need of a specification, the scraper 25 is made of cemented carbide, and the parameters of the spiral line of the scraper 25 are the same as the parameters of the spiral line of the second scraper transmission rod 23.

In addition, the scraper 25 can continuously scrape off the silt layer adhering to the outer wall of the filter barrel 12, and guide it into the impurity receiving chamber 4, which can reduce the probability of hard impurities blocking the filter holes.

[0055] Furthermore, two sets of the external scraping and clearing components are provided, and the two sets of the external scraping and clearing components are symmetrically distributed on the deceleration support component, so as to further improve the cleaning efficiency and the force stability during the crushing and scraping process.

When the water flow compression plate rotates in the filter barrel, it will push the fluid to slide quickly from the other side of the water flow compression plate to one side of the water flow compression plate, thereby quickly pushing the fluid from the filter hole to flush from the inside to the outside.

[0059] Furthermore, two sets of compressed water flow flushing parts are provided, and the two sets of compressed water flow flushing parts are evenly distributed around the flushing transmission pipe 27, and the two sets of compressed water flow flushing parts correspond one by one to the two sets of external scraping and clearing parts, further improving the automatic cleaning efficiency of the filter barrel 12.
