The invention relates to the field of elevators, in particular to a negative pressure elevator car with air disinfection and filtration functions. The technical problems that due to the fact that air circulation in an elevator shaft is poor, the quality of air exchanged by air exchange equipment is not high, people in a lift car are dense, the mobility of the people is large, under the condition that the current epidemic situation is not ended, air cannot be disinfected, and the risk of cross infection is increased are solved. According to the implementation scheme, the negative pressure elevator car with the air disinfecting and filtering functions comprises an elevator car body, negative pressure box bodies and negative pressure air exchange mechanisms, the negative pressure box bodies are fixedly connected to the upper side face and the lower side face of the elevator car body, the two negative pressure box bodies are symmetrically arranged up and down, and the negative pressure air exchange mechanisms are fixedly connected into the two negative pressure box bodies. By arranging the negative pressure air exchange mechanism, the purposes that air enters from the upper portion and exhausts from the lower portion when the elevator ascends and air enters from the lower portion and exhausts from the upper portion when the elevator descends are achieved, and the air exchange quality in the elevator is improved.

本发明涉及电梯领域，尤其涉及一种具有空气消毒过滤功能的负压电梯轿厢。技术问题：由于电梯井内的空气流通性差，导致换气设备交换的空气质量不高，且轿厢内的人员密集，人员流动性大，在当前疫情尚未结束的情况下，不能对空气进行消毒，导致交叉感染的风险增加。实施方案：一种具有空气消毒过滤功能的负压电梯轿厢，包括有电梯轿厢、负压箱体和负压空气交换机构，电梯轿厢的上下两侧面均固接有负压箱体，两个负压箱体上下对称设置，两个负压箱体内均固接有负压空气交换机构。本发明通过设置负压空气交换机构，实现了当电梯上行时，上部进气下部排气，电梯下行时，下部进气上部排气的目的，提高了电梯内部的空气交换质量。
