the branching portion is provided with a switching device that switches between a state in which airflow is allowed to flow through the fresh air side branch pipe and a state in which airflow is allowed to flow through the exhaust air side branch pipe.
9. The air treatment device of claim 1,
the fresh air fan is a centrifugal fan in which the extending direction of the rotation axis of the impeller, namely the axial direction, is consistent with the orientation of the fresh air vent.
10. An air treatment system, comprising:
the air treatment device of any one of claims 1 to 9; and
an air-conditioning indoor unit connected with the air treatment device through the air pipe,
the air-conditioning indoor unit is provided with a heat exchanger, a fresh air inlet component and an indoor unit fan,
the fresh air inlet component conveys fresh air from the air pipe to the heat exchanger,
the fan of the indoor unit sends fresh air which is sent into the heat exchanger by the fresh air inlet component and exchanges heat to the indoor space.
