TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning units, and particularly relates to an air conditioning unit with a dead angle-free air outlet function. BACKGROUND

[0002] In the field of modern air conditioning equipment, especially in the aspect of indoor temperature and air quality control, air conditioning units play a crucial role. Traditional air conditioning systems usually adopt fixed air outlet directions to deliver cold or hot air indoors. This design is prone to cause air flow dead angles, thereby causing significant indoor temperature differences and affecting user comfort.

[0003] Patent No. CN221648614U discloses a central air conditioning air outlet capable of adjusting the air outlet angle. The air outlet includes a square air outlet cylinder, a cover body fixedly connected to the lower end of the square air outlet cylinder, a hollow cavity formed in the cover body, an air outlet frame fixedly connected to the cover body and penetrating the cover body, an air guide cover fixedly connected to the air outlet frame and penetrating the cover body, and a sealing through groove formed in one side of the square air outlet cylinder. A rubber sealing plate is tightly sleeved in the sealing through groove, one side of the rubber sealing plate is fixedly connected to a dismounting plate with a handle, and the other side of the rubber sealing plate is provided with square frame one, square frame two and square frame three. In use, the mobile screw rod can be rotated by driving transmission wheel one, transmission wheel two and transmission belt by a servo motor, thereby driving the rotating rod and the air guide plate to rotate and adjusting the air outlet angle. Although this design can adjust the air outlet angle within a certain range, the adjustment range is limited to one plane, and full-range air flow coverage cannot be achieved. As a result, the temperature in the air outlet direction and other directions is not uniform, and a significant temperature difference occurs, which affects the use experience of the air conditioner. SUMMARY
