DAMPER AND CIRCULAR AIR-CONDITIONING AIR OUTLET
Document Type and Number:
WIPO Patent Application WO/2019/184673
Kind Code:
A1
Abstract:
A damper (1), wherein a base (11) has an inner cavity and is provided with openings in both ends; one end of a rotating part (12) is rotatably accommodated in the inner cavity of the base (11) and is adapted to the inner cavity in shape; one end of a transmission part (13) is rotatably accommodated in the inner cavity of the rotating part (12); a first friction part is provided between the rotating part (12) and the base (11), and a second friction part is provided between the transmission part (13) and the rotating part (12). Also provided is a circular air-conditioning air outlet, comprising a housing (3), a blade (2) provided in the housing, a gear (4), an air throttle (5), and the damper (1). The structure of the damper (1) is further simplified, so that the rotation of the damper (1) is smooth and stable, and the damper (1) can maintain more constant damping force. In addition, the housing strength of parts is enhanced in the production of the parts, thereby prolonging the service life, and the fineness requirements for size specifications are also reduced, thereby facilitating the production.
