An airflow detecting device includes a housing, a filter, a movable structure and a sensor. The filter is disposed on the housing so that a first airflow can pass through the filter. The movable structure is disposed near the filter and has an opening being closed or opened when the movable structure selectively stands in a first state or a second state. The sensor is disposed near the movable structure and within the housing. When the movable structure stands in the first state, the opening is closed and the first airflow passes through the filter and flows through the sensor for detecting. When the movable structure stands in the second state, the opening is opened and a second airflow passing through the opening enters the housing and flows through the sensor for detecting.
