Technical Field

[0001] The utility model relates to the technical field of air-conditioning outlets, in particular to a redirecting structure of an air-conditioning outlet for heating, ventilation and air conditioning. Background Art

[0002] The redirecting structure is a device that can change the wind direction of the air outlet of the HVAC. When using the redirecting structure, the motor drives the rotating rod to rotate, which in turn drives the first bevel gear evenly fixed on the surface of the rotating rod to rotate. Because the first bevel gear and the second bevel gear are engaged with each other, the blades can be driven to rotate well, thereby changing the air outlet angle of the air conditioner.

[0003] The inventors found in their daily work that the redirecting structure of the air outlet of an HVAC system still has at least the following problems: when using the redirecting structure, the rotating rod is driven to rotate by the motor, thereby driving the first bevel gear evenly fixed on the surface of the rotating rod to rotate. Because the first bevel gear and the second bevel gear are engaged with each other, this can drive the blades to rotate well, thereby changing the air outlet angle of the air conditioner. However, in actual use, a certain amount of dust will accumulate on the blades after long-term use, and the redirecting structure is mostly connected to the air conditioner, which makes it more troublesome to clean.
