The invention discloses an elevator car ventilation device, and relates to the technical field of elevator equipment. The device comprises a ventilation pipe arranged at the top of a lift car in a penetrating mode, the bottom end of the ventilation pipe is connected with an air inlet filtering device, the bottom end of the air inlet filtering device is connected with a mounting pipe, and an air inlet fan is fixed in the mounting pipe; the outer side wall of the mounting pipe is fixed in the lift car through at least three fixing rods; and a suspended ceiling structure used for blocking wind is arranged on the inner side wall of the lift car located under the mounting pipe. In the elevator running process, an air inlet fan is controlled to be started, at the moment, air near the outer side of the top of a lift car is sucked into the lift car through a ventilation pipe under the action of the air inlet fan, and air is filtered through an arranged air inlet filtering device; therefore, ventilation of the elevator car is achieved.
本发明公开了一种电梯轿厢通风装置,涉及电梯设备技术领域。本发明包括贯穿设置在轿厢顶部的通风管,通风管底端连接有进风过滤装置,进风过滤装置的底端连接有安装管,安装管内固定有进风风机;安装管的外侧壁通过至少三根固定杆固定在轿厢内;且位于安装管正下方的轿厢内侧壁上设置有用于挡风的吊顶结构。本发明通过电梯运行过程中,控制进风风机启动,此时在进风风机的作用下通过通风管将轿厢顶部外侧附近的空气抽入轿厢内部,且通过设置的进风过滤装置进行过滤;从而实现电梯轿厢的通风换气。
