The airway unit may comprise an operating member; a pipeline, and a control mechanism, The pipeline may be formed with an air connection portion. The air connection portion may have a first air connection passage and a second air connection passage. The air pump may be attached to the pipeline. The control mechanism may be coupled on the pipeline. The operating member may be connected to the control mechanism in a driving manner. The operating member and the control mechanism may cooperate to control the airway unit to change to a first intake state in which the first air connection passage is inflated by the air pump, an exhaust state in which the second air connection passage is exhausted by the air pump, and a second intake state in which the second air connection passage is inflated by the air pump.
