The outlet of the inlet pipe 4 has an outlet adapter 41 that communicates with the inlet of the inner cylinder shaft. Specifically, the outlet adapter 41 is hemispherical. When water is introduced, the water coming out of the outlet of the inlet pipe 4 first enters the outlet adapter 41, and then enters the inner cylinder shaft through the outlet adapter 41. The water in the inner cylinder shaft enters the inner cylinder through the outlet of the inner cylinder shaft.
