Water ejected from the second arc tube (8) impacts the surface of the force-bearing plate (14), causing the force-bearing plate (14) to rotate around the rotating ring (12) after being subjected to force. The scraper (15) rotates along with the force-bearing plate (14). The side of the scraper (15) away from the force-bearing plate (14) is supported on the bottom of the first shell (1) and the second shell (2). After the force-bearing plate (14) rotates, the scraper (15) scrapes impurities located at the bottom of the first shell (1) and the second shell (2), so that the impurities are sucked into the suction hole (10) on the surface of the second built-in tube (9) along with the water.
