[0022] In this embodiment, the main air duct 1, the front defrost air outlet 2, the air duct 3 and the lateral defrost air outlet 4 constitute the main structure of the defrost duct for the automobile air conditioner involved in this application, wherein the main air duct 1 is the automobile air conditioner defrost air duct.
[0023] Specifically, the front defrost air outlet 2 and the lateral defrost air outlet 4 are connected in a T-shaped structure, and the lateral defrost air outlet 4 is connected and fixed to the front defrost air outlet 2 by an annular clamping strip clamped on the outer wall thereof.
[0024] Specifically, the main air duct 1, the front defrost air outlet 2, the air duct 3 and the lateral defrost air outlet 4 are all made of the same material as the shell 49, so that the entire air conditioning duct has antibacterial, pressure-resistant and wear-resistant properties.
[0025] Specifically, a plastic anti-aging agent is added to the polypropylene substrate 494 to enhance the anti-aging and cracking performance.
[0026] Specifically, the rotating shaft 44 is arranged along the axial direction of the transverse defrost air outlet 4 , and the rotating shaft 44 is located on the axis of the transverse defrost air outlet 4 , and at the same time, both ends of the rotating shaft 4 do not exceed the two side ports of the transverse defrost air outlet 4 .

The steel ring reinforcement ribs are used to form a metal wire on the outside of the defrost air outlet duct for enhanced protection, and at the same time, the mechanical strength inside the substrate layer is increased, so that it has a certain pressure-resistant buffering effect, and the stability of the defrost duct itself is increased. At the same time, a plastic anti-aging agent is added to the polypropylene substrate to increase the shell's anti-aging and cracking performance.
[0032] The utility model can effectively solve the problems of functional deviation in the existing automobile air-conditioning defrost pipe and the inconvenience in cleaning the inside of the pipe.
