The automatic ventilation device comprises a lift car and a fan, the lift car is arranged in a hoistway in a vertically movable mode, an air inlet is formed in the bottom of the lift car, an air outlet is formed in the top of the lift car, the fan is arranged at the air outlet, and the fan is used for extracting air in the lift car from bottom to top. According to the device, the air inlet is formed in the bottom of the lift car, the air outlet is formed in the top of the lift car, the draught fan is an exhaust fan, when the draught fan works, external air can enter the lift car through the air inlet and then is extracted and exhausted by the draught fan through the air outlet in the top, and under the condition, airflow in the lift car flows from bottom to top; in addition, airflow exhaled by the passengers can flow upwards, so that foul air exhaled by the passengers can be easily sucked away by the fan, transverse fluid channeling is avoided, the probability that viruses are spread and diffused in the lift car is effectively reduced, and the passengers are not prone to being damaged by polluted air.

    本发明公开了一种厢式电梯自动换气装置,包括:轿厢和风机,所述轿厢可上下移动地设于井道内,所述轿厢的底部设有进风口,顶部设有排风口,所述风机设于所述排风口处,所述风机用于从下往上地抽取所述轿厢内的空气。本装置在轿厢的底部设有进风口,顶部设有排风口,风机为抽风机,当风机工作时,外部空气会通过进风口进入轿厢,然后通过顶部的排风口被风机抽取并排出,这种情况下轿厢内的气流是从下往上流动的,再加上乘客呼出的气流也会向上流动,因此乘客呼出的浊气会很容易被风机抽走,不会横向窜流,有效降低了病毒在轿厢内传播扩散的几率,使得乘客不容易受到污染空气的侵害。
