[0030] The inclined design of the supporting transverse plate 7 allows water entering the interior of the side shell 2 to fall from the inclined surface to prevent the water from accumulating and staying on the supporting transverse plate 7 .

[0031] A side shell 2 is fixedly installed on the end of the base 1 away from the ground, and an eave is provided on the end of the side shell 2 close to the drive motor 8, and a square is penetrated on the outer surface of one side of the side shell 2, and a top cover 4 is fixedly installed on the end of the side shell 2 away from the base 1, and a circular through hole is opened at the center of the top cover 4, and the circular through hole of the top cover 4 is concentric with the drive motor 8. A convection structure is provided inside the base 1, and the heat generated by the air conditioner is discharged through the convection structure. The convection structure includes: a connecting shaft 9, the connecting shaft 9 is fixedly installed on the output end of the drive motor 8, and a first fan blade 10 is fixedly installed on the end of the connecting shaft 9 close to the drive motor 8, a bottom exhaust port 5 is penetrated on the outer surface of the base 1, and a second fan blade 11 is fixedly installed on the end of the connecting shaft 9 located outside the base 1, and the second fan blade 11 is concentric with the first fan blade 10.

[0032] The rotation of the driving motor 8 can drive the connecting shaft 9 to rotate together, so that the first fan blade 10 rotates. Through the rotation of the first fan blade 10, the external cold air is drawn into the base 1 from the bottom exhaust port 5, and then the cold air is sent into the side shell 2 to take away the heat generated by the heat sink 13. At the same time, the second fan blade 11 will rotate to draw out the air in the side shell 2, forming convection to quickly discharge the hot air in the side shell 2 from the top cover 4 to achieve cooling.

At the same time, the splint part 12 can be used to fix and position the connecting shaft 9 to prevent the connecting shaft 9 from deforming during rotation and causing damage to the second fan blade 11.

[0040] When in use, the water pump 15 will pump the water collected in the condensate receiving tray 14 into the side spray pipe 16. At the same time, the inclined design of the condensate receiving tray 14 allows the condensate in the tray to be centrally pumped out, and the water is sprayed onto the heat sink 13 through the side spray pipe 16 to cool the heat sink 13. At the same time, excess water mist will be discharged from the side shell 2 through the first fan blade 10 and the second fan blade 11, so that the collected condensate can be reused.
