[0023] Please refer to Figure 5 , the fan 7 is adapted to the dust-proof net 6. The movable rod 12 is movably connected to the inner wall of the limit card slot 9. A handle is welded on the surface of the box door 15. By setting the handle, it connects the user and the box door 15, thereby driving the box door 15 to rotate.

[0024] Please refer to Figure 4 , a slag storage tank 16 is placed on the top of the rainwater collection tank 3. A semiconductor refrigerator 17 is fixedly connected to one side of the rainwater collection tank 3. The air outlet end and the air inlet pipe of the semiconductor refrigerator 17 penetrate into the inner cavity of the rainwater collection tank 3 and are communicated with a cooling pipe 18. A water outlet pipe 19 is communicated with the surface of the rainwater collection tank 3.
