The invention discloses an air interchanger for an elevator car, and belongs to the technical field of elevator cars, the air interchanger for the elevator car comprises a car, and further comprises an air inlet cylinder, two air inlet channels and a filter plate are arranged in the air inlet cylinder, and the filter plate is used for filtering air entering the air inlet cylinder; the blocking mechanism is used for blocking the air inlet channels on the two sides so as to prevent air inlet; according to the scheme, the air inlet channel on one side can be blocked through the blocking mechanism, the filter plate in the blocked air inlet channel on one side can be taken out to be cleaned or replaced, and the filter plate in the air inlet channel on the other side can be normally used for filtering, so that normal continuous operation of ventilation in the lift car is realized, and the ventilation efficiency is improved. The situation that the ventilation device or the elevator is stopped is not needed, the influence on normal use of passengers is greatly avoided, the use effect is good, and the practicability of the lift car in the device is greatly improved.
本发明公开了一种电梯轿厢用换气装置,属于电梯轿厢技术领域,一种电梯轿厢用换气装置,包括轿厢,还包括:进气筒,进气筒的内部设有两个进气通道,过滤板,用于对进入到进气筒中的空气进行过滤;封堵机构,用于分别对两侧的进气通道进行封堵以防止进气;本方案可通过封堵机构堵住其中一侧的进气通道,即可将被堵住的一侧进气通道内的过滤板取出进行清洗或者更换处理,而另一侧的进气通道内的过滤板还在正常进行过滤使用,从而实现了轿厢内换气的正常持续运行,不需要将换气装置停止或者电梯停运的情况,极大避免对乘客的正常使用造成影响,使用效果好,极大提高了本装置中轿厢的实用性。
