Abstract
An air flow sensing device includes a casing, a filter member disposed in the casing, a sensor and a guiding member. The casing has an accommodating space, a first opening, a second opening and a third opening. The sensor is disposed in the accommodating space. The guiding member is disposed in the casing and can be switched between a first state and a second state. When the guiding member is switched to the first state, the first opening, the accommodating space and the second opening form a first passage, such that a first air flow outside the casing passes through the sensor via the first passage. When the guiding member is switched to the second state, the first opening, the accommodating space and the third opening form a second passage, such that a second air flow, which passes through the filter member, passes through the sensor via the second passage.
