[0002] An air pipe steering structure is a structure or device for changing the direction of an air pipe path, which can ensure that the air pipe reduces obstacles and remains unobstructed during the steering process, and prevent the air pipe from being damaged due to excessive bending during the steering process. The air pipe steering structure is widely used in fluid conveying systems or pneumatic comfort systems.

[0003] Currently, the air pipe steering structure is usually a snap-on steering structure, which has an opening groove for accommodating the air pipe, and limit protrusions distributed on the opening periphery of the opening groove.
