In the embodiment shown in fig. 7, when the detected carbon monoxide concentration value is smaller than the preset limit value, the indicating light is green, which indicates that carbon monoxide does not need to be removed, and the closing plate 230 is controlled to close the opening of the first cavity 202; when the concentration detection value of the carbon monoxide is equal to the preset limit value, the indicating light is yellow, the user is reminded of paying attention at the moment, and the closing plate 230 does not rotate; when the concentration detection value of the carbon monoxide is larger than the preset limit value, the indicating light is red, at this time, the closing plate 230 is controlled to rotate to open the opening of the first accommodating cavity 202, the airflow in the vehicle can flow into the first accommodating cavity 202 through the vent 201, and the carbon monoxide in the airflow is removed through the absorbent 220 in the first accommodating cavity 202.

In a specific embodiment, the different indicator lights 500 may emit different colors of indicator lights, or the same indicator light 500 may switch the different colors of indicator lights.

In a specific embodiment, the sensor 300 monitors the carbon monoxide concentration detection value in the vehicle in real time, the indicator lamp emits different colors of indicating light according to the carbon monoxide concentration detection value, and the controller controls the closing plate 230 to rotate according to the indicating light.
