[0030] like Figure 1、 Figure 3 and Figure 5 Through holes 4 are provided at the center and bottom of the middle partition 3, and the through hole 4 in the center is larger than the through hole 4 at the bottom, which can reduce the inertia of the liquid and enable the left and right cavities to be connected. Two water outlet heads 8 are installed on the top of the circulating water pipe 7, and the water outlet heads 8 are located on the left and right sides of the partition 3, which is convenient for mixing the liquid in the water tank 2.
