The rotor 20 has an outlet end surface 22, an annular wall surface 24, a first groove 26 formed on the annular wall surface 24, a second groove 28 formed on the annular wall surface 24, and a groove connected to the outlet end surface 22. The annular tapered wall 29 between the annular wall surface 24, the first groove 26 intersects with the outlet end surface 22 to form a first gap 261 in the outlet end surface 22, the first groove 26 has a first bottom The two ends of the wall 263 and the first bottom wall 263 intersect with the outlet end surface 22 and the annular wall surface 24 respectively, and the second groove 28 intersects with the outlet end surface 22 to form a second gap 281 at the outlet end surface 22. The second groove 28 has a second bottom wall 283, and the two ends of the second bottom wall also intersect the outlet end surface 22 and the annular wall surface 24 respectively. In this embodiment, the first, second bottom walls 263, 283 is curved, as shown in FIG. 4 , but in other possible embodiments, the first and second bottom walls can also be in other shapes, such as flat. The rotor 20 abuts against the outlet end wall 18 of the body 10, more specifically, the annular conical wall 29 abuts against the conical annular inner wall 183, so that the outlet end surface 22 of the rotor 20 is exposed from the opening 181 , the first notch 261 and the inner edge of the outlet end wall 18 enclose the first liquid spray hole 40 , and the second notch 281 and the inner edge of the outlet end wall 18 enclose the second liquid spray hole 50 .
