The invention relates to a gradually-closed air door structure arranged on a shell, and an air inlet is formed in the shell. The air door structure comprises an air door plate and a rotating center seat which are integrally formed, and the rotating center seat is arranged at the end of the air door plate and rotationally connected to one side of an air inlet through a shaft; first sealing flexibleglue and second sealing flexible glue are connected to the side edge of the air door plate in an embedded mode. Third sealing flexible glue is connected to the side, away from the rotating center base, of the air door plate in an embedded mode. The outer side of the air inlet is connected with a first door stop and a second door stop; and in the rotating process of the air door plate, a gap is kept between the third sealing flexible glue and the second door stop. Compared with the prior art, the gradually-closed air door structure has the advantages that the air door adopts a gradual structure, so that the air door is not blocked when opened and closed, and the noise is reduced; abrasion of the air door in the operation process is relieved, and the sealing performance is ensured.

    一种渐进关闭的风门结构,设置于壳体上,所述壳体上设置有进风口;该风门结构包括一体成型的风门板和旋转中心座,旋转中心座设置于风门板端部,旋转中心座通过轴转动连接于进风口一侧;所述风门板侧边嵌入连接有第一密封软胶和第二密封软胶,风门板远离旋转中心座一侧嵌入连接有第三密封软胶;所述进风口外侧连接有第一门挡和第二门档;所述风门板在转动过程中,第三密封软胶与第二门档保持间隙。与现有技术相比,本发明的一种渐进关闭的风门结构,风门采用渐进结构,风门开关时不卡滞,降低噪音;减缓风门在运行过程中的磨损,确保密封性。
