[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A motor 9 is fixedly installed on the upper end of the mounting shell 4, and the output shaft of the motor 9 is rotatably connected to the mounting shell 4. A bevel gear 10 is fixedly sleeved on the outer side of the output shaft of the motor 9. A rotating rod 11 is rotatably connected to the inside of the mounting shell 4. A filter screen 14 is slidably connected to the inner wall of the mounting shell 4. A connecting plate 15 is fixedly connected to the end face of the filter screen 14 away from the controller 2.
