By providing the mounting opening 17 on the top surface of the bin body 1, the charging machine 2 is placed into the charging area 12 from the top instead of from the side, so that there is no need to provide a charging door on the side of the bin body 1 for placing the charging machine 2, and the charging machine 2 is placed into the charging area 12 through the mounting opening 17. The cover 6 is connected to the top surface of the bin body 1 and covers the mounting opening 17, so that the cover 6 plays a waterproof covering role in the bin body 1. The cover 6 and the bin body 1 are detachably connected, which facilitates the placement and removal of the charging machine 2. At the same time, the opening of the mounting opening 17 provided on the top surface of the bin body 1 is small, which facilitates the processing and manufacturing, and facilitates the covering of the cover 6.

[0119] A sealing ring 45 is arranged between the charging machine 2 and the charging cabinet 4 and surrounds the air outlet 42. The charging machine 2 is placed into the charging area 12 through the mounting opening 17 and abuts against the charging cabinet 4, a sealing ring 45 is arranged between one side of the charging machine 2 and the charging cabinet 4, and the air duct structure 31 abuts against the other side of the charging machine 2 and is provided with a sealing strip 33. The sealing ring 45 surrounds the air outlet 42, thereby enhancing the sealing effect between the charging machine 2 and the charging cabinet 4, effectively avoiding that the heat of the exhaust passage flows into the bin body 1 through the charging machine 2 and the charging cabinet 4, and effectively avoiding that the temperature in the bin body 1 is too high to cause safety and damage problems to the equipment in the charging machine 2.

[0120] The cover 6 has a lifting lug 63, and the lifting lug 63 is used to apply a force on the lifting lug 63 by a lifting device, thereby facilitating the installation and removal of the cover 6.

The connection strength is high. The four corners of the cover 6 are welded with connecting pieces, the connecting pieces are provided with connecting holes, and the bin body 1 is connected to the connecting pieces by bolts.

[0122] The top surface of the bin body 1 has an upwardly protruding blocking portion 18 which continuously and uninterruptedly surrounds the mounting opening 17, and the cover 6 covers the blocking portion 18. The upwardly protruding blocking portion 18 can block the water outside from entering the bin body 1 through the mounting opening 17, thereby further enhancing the waterproof effect of the charging bin. At the same time, the blocking portion 18 is located at the mounting opening 17 and plays a reinforcing role, thereby effectively enhancing the structural strength and realizing higher stability.

[0123] The four peripheral edges of the cover 6 have downwardly extending buckling parts 61 which are sleeved on the blocking part 18. The cover 6 is connected with the cartridge body 1 by sleeving the buckling parts 61 on the blocking part 18, which facilitates accurate positioning between the cover 6 and the cartridge body 1 and realizes high connection stability of the cover 6 on the cartridge body 1. Meanwhile, the water on the cover 6 is discharged towards the top surface of the cartridge body 1 and outwardly by the buckling parts 61, which avoids accumulation on the cover 6 and guarantees the waterproof effect of the charging cartridge. The top surface of the cover 6 can be inclined or arc-shaped, which is beneficial to water discharge.

[0124] The cover 6 has a heat preservation layer 62. The heat preservation layer 62 has heat preservation and insulation effects, which effectively avoids heat leakage from the cartridge body 1 to the outside of the cartridge body 1 through the mounting port 17 and the cover 6, guarantees the temperature in the cartridge body 1 and improves the safety and stability of the charging cartridge. The heat preservation layer 62 can be attached to the inner wall surface of the cover 6 and located in the cartridge body 1, and the cover 6 can also have a containing cavity for containing the heat preservation layer 62.
