The invention is suitable for the technical field of elevators, and provides an oxygen increasing device and an elevator car. The oxygen increasing device detects the oxygen concentration in the elevator car, whether a car door is closed or not and whether a person exists in the elevator car or not, and when the oxygen concentration in the elevator car is lower than a concentration threshold value, the car door is closed and the person exists in the elevator car, the oxygen increasing device is started; and the electric control air valve of the oxygen bottle is controlled to be opened to output oxygen, so that the oxygen concentration in the elevator car reaches the concentration threshold value, oxygenation is carried out in the elevator car, and the comfort of passengers in the elevator car can be improved.
本申请适用于电梯技术领域,提供一种增氧装置及电梯轿厢,其中,增氧装置通过检测电梯轿厢内的氧气浓度、轿门是否关闭以及电梯轿厢内是否有人,并在电梯轿厢内的氧气浓度低于浓度阈值、轿门关闭且电梯轿厢内有人时,控制氧气瓶的电控气阀开启以输出氧气,使电梯轿厢内的氧气浓度达到浓度阈值,对电梯轿厢内进行增氧,可以提高电梯轿厢内乘客的舒适性。
