The invention discloses a medical elevator ceiling ventilation structure capable of guaranteeing the air quality in an elevator car, and belongs to the technical field of elevators. The medical elevator ceiling ventilation structure comprises an elevator car main body, wherein a first drainage cylinder is clamped to the top of the elevator car main body, and a first primary filter screen is clamped to the inner side wall of the first drainage cylinder. According to the invention, by matching designed structures such as fan blades, a driving gear, a driven gear, a driving gear, a second surface-mounted ultraviolet germicidal lamp, a drainage fan, a first annular filter screen and a second annular filter screen, on the basis of realizing automatic control, it is not needed to arrange a lot of control assemblies additionally. By means of a switching mode of a drainage fan, a good backflushing effect can be achieved, air impurities intercepted in the first annular filter screen and the second annular filter screen can be effectively removed, the normal service lives of the first annular filter screen and the second annular filter screen are effectively prolonged, and the cleaning and replacing frequency of the first annular filter screen and the second annular filter screen is reduced.

    本发明公开了一种可保证轿厢内部空气质量的医用电梯顶棚通风结构,属于电梯技术领域,包括轿厢主体,所述轿厢主体的顶部卡接有第一引流筒,所述第一引流筒的内侧壁上卡接有第一初级过滤网。本发明中,通过设计的风叶、主动齿轮、从动齿轮、主动齿轮、第二贴片式紫外线杀菌灯、引流风机、第一环形过滤网以及第二环形过滤网等结构的互相配合下,能够实现自动控制的基础上,无需增设大量的控制组件,利用引流风机的切换方式,从而可实现良好的反冲效果,能够有效去除被截留在第一环形过滤网和第二环形过滤网内部的空气杂质,有效延长了第一环形过滤网和第二环形过滤网的正常使用寿命,减少第一环形过滤网和第二环形过滤网的清洗和更换频率。
