[0027] Two plate portions 101 are arranged back to back at intervals, and the plate portion 101 forms a cone 102 eccentrically arranged with its own contour, and the cone 102 forms a cavity 103 parallel to the axial direction of the plate portion 101, and the bottom wall of the cone 102 forms a through hole 104 connected to the cavity 103. One end of the distribution body 105 extends between the two plate portions 101, and the connecting body 106 is arranged on both sides of the through hole 104. The distribution body 105 is connected to the cone 102 through the connecting body 106, and the riser portion 107 is connected to the end of the distribution body 105 away from the plate portion 101.
