The invention relates to the technical field of elevators, in particular to an elevator car ventilation system which comprises a car body and a ventilation assembly, an air inlet communicated with a shaft and the car body is formed in the lower portion of the side wall of the car body, an air outlet communicated with the shaft and the car body is formed in the top of the car body, and the ventilation assembly comprises an air guide pipe and a movable plate. One end of the air guide pipe is connected with the air inlet, the other end of the air guide pipe is connected with the air outlet, at least one first opening evenly formed along the axis of the air guide pipe is formed in the side wall of the air guide pipe, and the movable plate can be attached to the air guide pipe in a sliding mode in the height direction of the lift car body. A second opening capable of working in cooperation with the first opening is formed in the movable plate. Through cooperation of the air guide pipe and the movable plate, the exchange degree of moving airflow is large when the lift car body moves when no weight exists in the lift car body, and the exchange degree of the airflow is small when the lift car body moves when the weight exists in the lift car body.

    本发明涉及电梯技术领域,具体是涉及一种电梯轿厢通风系统,包括轿厢体和通风组件,轿厢体的侧壁下部开设有连通井道和轿厢体的进气孔,轿厢体的顶部开设有连通井道和轿厢体的出气孔,通风组件包括导气管和活动板,导气管的一端与进气孔连接,导气管的另一端与出气孔连接,导气管的侧壁上开设有至少一个沿着导气管的轴线均匀设置的第一开口,活动板能够沿着轿厢体的高度方向滑动的与导气管贴合,活动板上开设有能够配合第一开口工作的第二开口。本发明通过导气管和活动板配合使得轿厢体内部无重量时轿厢体进行时移动气流的交换程度较大,当轿厢体内部存在重量时轿厢体移动时气流的交换程度较小。
