MULTI-DIRECTIONAL SMOOTH DAMPER

A multi-directional smooth damper includes a base including an inner cavity, two ends of the inner cavity defining openings, a first rotating portion, and a second rotating portion. A first end of the first rotating portion is rotated and disposed in the inner cavity of the base and a shape of the first end of the first rotating portion corresponds to a shape of the inner cavity. A second end of the first rotating portion passes through an opening of one end of the base. The first rotating portion is disposed at one end of the base having the opening and the inner cavity. A first end of the second rotating portion is rotated and disposed in an inner cavity of the first rotating portion. A grease layer is coated between a surface of the first rotating portion and the surface of the inner cavity of the base. The invention also provides a circular air conditioner vent, comprising a housing, a blade disposed in the housing, an air door, and the damper. The damper used in the invention can realize the unified function of the opening and closing adjustment of the blowing amount and the direction of the blowing direction of the circular air-conditioning vent, also simplify the structure of the device, save the operation space and be simple in operation. The grease layer not only provides good lubrication, but also provides a constant damping force, which can achieve smooth rotation in multiple directions and maintain stable holding force.
