[0035] The shell of the vertical shell 4 is provided with a heat exhaust square port 41 corresponding to the axial flow heat exhaust mechanism 22 , and the inner surface of the vertical shell 4 is connected with an air induction component 42 , and the position of the air induction component 42 corresponds to the heat exhaust square port 41 .

[0036] For details, please refer to the attached Figure 2 and 3 The axial flow heat dissipation mechanism 22 includes an axial flow motor 221 connected to a side surface of the support frame 21, a rotating head 222 connected to an output end of the axial flow motor 221, and a plurality of fan blades 223 connected to an outer surface of the rotating head 222;

[0037] The air induction assembly 42 includes an upper support box 421 and a lower support box 422 connected to the inner surface of the vertical shell 4. The upper support box 421 and the lower support box 422 are symmetrically arranged on both sides of the heat exhaust square port 41. A plurality of air induction blades 423 are connected between the upper support box 421 and the lower support box 422.

[0038] The air induction blade 423 is a hollow structure, and an air inlet hole 4231 is provided at one end of the air induction blade 423.

[0042] For details, please refer to the attached Figure 3 and 4 The upper support box 421 and the lower support box 422 are hollow structures. The first air duct 424 is provided on both sides of the upper support box 421. The upper and lower ends of the first air duct 424 are connected with connecting pipes 425. The first air duct 424 is connected to the upper support box 421 and the lower support box 422 through the connecting pipes 425.

[0043] A plurality of second air ducts 426 are connected to one side of the first air duct 424. The plurality of second air ducts 426 on the same side are arranged sequentially from top to bottom.

[0044] A third air duct 428 is connected between the two second air ducts 426 on the opposite side, and a plurality of second air exhaust heads 429 are connected to the tube body of the third air duct 428;

[0045] It should be noted that, in this embodiment, the first air duct 424 is connected to the upper support box 421 and the lower support box 422 through the connecting pipe 425, so that the hot air in the upper support box 421 and the lower support box 422 can enter the first air duct 424 through the connecting pipe 425. Since the first air duct 424 is connected to the plurality of second air ducts 426, the hot air is discharged from one end of the plurality of second air ducts 426 away from the first air duct 424, thereby defrosting the condenser 2.

[0046] Furthermore, hot air is discharged from multiple points of the condenser 2 through the first air discharge head 427 to accelerate the defrosting of the condenser 2;

Since the third gear 4234 is meshed with one of the first gears 4233, the first gear 4233 is driven to rotate. When the first gear 4233 rotates, the adjacent second gear 4236 is driven by the first gear 4233. Since the two adjacent first gears 4233 are connected by the second gear 4236, the multiple first gears 4233 are rotated synchronously and in the same direction. Since the first gear 4233 is coaxially arranged with the draft blade 423, the draft blade 423 is allowed to adjust its angle. In this way, the draft blade 423 guides the direction of the airflow so that the airflow meets the air conditioning installation requirements.

[0052] The specific operation mode of the present invention is as follows:

[0053] When the air conditioner defrosting device is used, the rotating head 222 is driven by the axial flow motor 221, and the fan blades 223 are driven by the rotating head 222, so that the airflow generated by the fan blades 223 drives the hot air in the air conditioner to be discharged, and the hot air is blown toward the air guide blades 423;

[0055] The first air duct 424 is connected to the upper support box 421 and the lower support box 422 through the connecting pipe 425, so that the hot air in the upper support box 421 and the lower support box 422 can enter the first air duct 424 through the connecting pipe 425. Since the first air duct 424 is connected to the plurality of second air ducts 426, the hot air is discharged from one end of the plurality of second air ducts 426 away from the first air duct 424, thereby defrosting the condenser 2.

[0056] By setting the third air duct 428, the hot air in the second air duct 426 can enter the third air duct 428, and the hot air is discharged through the second air discharge head 429 on the third air duct 428. The hot air is blown toward the condenser 2 to accelerate the all-round defrosting of the condenser 2.
