At the same time, each first water inlet hole 11 is inclined upward by 30-45° (the upward inclination angle b can be any value between 30-45°, such as 30°, 35°, 40°, 45°, etc.). And each first water inlet hole 11 is in the shape of a strip extending along the circumference of the side wall of the crushing cavity 10, the length of the strip is 10-15 mm (which can be any value between 10-15 mm, such as 10 mm, 11 mm, 13 mm, 15 mm, etc.), and the width of the strip in the up-down direction is 1.5-2.5 mm (which can be any value between 1.5-2.5 mm, such as 1.5 mm, 2 mm, 2.5 mm, etc.).

[0039] As shown in Figs. 4-6 the above-mentioned second water inlet hole 12 has a plurality of intervals arranged on the side wall of the crushing cavity 10 in the circumferential direction, is located below the first water inlet hole 11, and is inclined downward to flush the components below the first water inlet hole 11.
