[0027] As Figures 4 to 5 As shown, multiple fixed blocks 2 are fixedly connected in the bottom of shell 1;Connection frame 21 is fixedly connected in the middle of fixed block 2;Fan 22 is rotationally connected in the middle of connection frame 21;When fan blade 17 of lower end runs, air current blown will contact fan 22, when air current contacts fan 22, fan 22 will be pushed to rotate, fan 22 will accelerate air current flow in the bottom of shell 1 at this time, to reduce air current accumulation, by which cold air is pushed to scatter to the rest of shell 1;By increasing fan 22, air current after being cooled by fan blade 17 is blown to rotate to accelerate air current flow to reach the inside of shell 1 to cool down.
