A rotating fan blade 19 is rotatably provided on the lower end surface of the support plate 21. Thus, the rotating fan blade 19 plays a role in heat dissipation. Water pumping frames 22 are fixedly provided on the left and right side end faces of the main box body 11. A water pumping cavity 23 is provided inside the water pumping frame 22. A water pumping fan blade 25 is rotatably provided between the front and rear walls of the water pumping cavity 23. Thus, the water pumping fan blade 25 plays a role in pumping water. Rain shelter frames 27 are fixedly provided on the left and right side end faces of the main box body 11. The rain shelter frames 27 play a role in preventing splashing.

[0025] A dismountable rack 28 is provided between the rain shelter rack 27 and the main box body 11. A filter screen 29 is fixedly arranged inside the dismountable rack 28. Thus, the filter screen 29 plays a role in filtering dust. Threaded cavities 31 are provided on the left and right side end faces of the main box body 11 and penetrate through the dismountable rack 28. Screws 30 are rotatably arranged inside the threaded cavities 31. The screws 30 are in threaded cooperation with the threaded cavities 31.

[0026] A water pumping motor 26 is fixedly arranged inside the rear wall of the water pumping cavity 23. The rear end face of the water pumping fan blade 25 is power-connected to the water pumping motor 26. A one-way valve 24 is fixedly arranged inside the water pumping rack 22. Thus, the one-way valve 24 plays a role in one-way drainage.

[0027] Two groups of wires 13 which are inclined and evenly distributed up and down are fixedly arranged on the rear end face of the power module body 17 and penetrate through the waterproof rack 14 and the main box body 11.

[0030] Specific working process:

[0031] When in use, at this time, the power module body 17 starts to work. At this time, the rotating motor 18 starts to start, thereby driving the rotating fan blade 19 to start rotating at a high speed. At this time, the outside air enters the storage cavity 12 through the filter screen 29, and then enters the air intake cavity 20 and the holding cavity 16 through the storage cavity 12, thereby realizing the rapid heat dissipation and cooling of the power module body 17. And once the water level is too high and enters the storage cavity 12 through the filter screen 29, at this time, the water level will rise in the storage cavity 12. When it overflows the water level sensor 15, at this time, the water level sensor 15 starts to detect that the water level is too high. At this time, the water pumping motor 26 starts to start, thereby driving the water pumping fan blade 25 to start rotating at a high speed, thereby driving the water accumulated in the storage cavity 12 to be discharged to the outside through the one-way valve 24. Thus, since the air intake cavity 20 is arranged above, it is ensured that water will not enter the holding cavity 16 and will not splash into the holding cavity 16.

[0032] Due to long-term use, dust often accumulates on the outer side of the filter net 29. At this time, start turning the screw 30. At this time, the screw 30 moves away from the threaded cavity 31. Then start pulling out the disassembly rack 28 and the filter net 29 downward, so as to facilitate the cleaning of the dust outside the filter net 29. When the cleaning is completed, push in the disassembly rack 28 and the filter net 29 and tighten the screw 30, thus ensuring the installation and disassembly of the filter net 29 and the disassembly rack 28.

[0033] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
