FThe invention provides a railway train ventilation component and a ventilation device with a dustproof function. A main body is included, the inner wall of the main body is provided with an air interchanger, the air interchanger is fixedly provided with a mounting bracket, the mounting bracket is provided with a ventilation fan, the inner wall of the main body is provided with a fixed shell, and a connecting spring is mounted in the fixed shell. According to the railway train ventilation component and the ventilation device with the dustproof function, when ventilation is finished, the ventilation fan in the air interchanger stops running, the connecting spring pushes a movable rod to return to the initial position through a compressed elastic force, and therefore a movable pull rod is promoted to drive dustproof baffles to be in a closed state; and through closing of the dustproof baffles, external dust and sundries are effectively prevented from entering so that the dust and the sundries are effectively prevented from remaining in the device to affect normal use of the device, and the device achieves the effect of automatic dust prevention when air exchange is not needed.
本发明提供一种铁路列车换气部件且具有防尘功能的通风装置,包括主体,所述主体的内壁上设置安装有换气装置,所述换气装置的固定安装有安装支架,所述安装支架上设置安装有换气风扇,所述主体的内壁上设置安装有固定壳体,所述固定壳体的内部设置安装有连接弹簧。该铁路列车换气部件且具有防尘功能的通风装置,且当换气结束时,通过换气装置内部的换气风扇停止运行,连接弹簧通过压缩的弹力推动活动杆回复至初始位置,从而促使活动拉杆带动防尘挡板形成关闭状态,且通过防尘挡板之间的闭合,有效地避免了外部灰尘与杂物的进入,从而有效的避免了灰尘与杂物残留在其内部影响其的正常使用,且使设备达到了不需要换气时自动防尘的效果。
