4. The fresh air device of claim 3, further comprising a turbid wind assembly, wherein the turbid wind assembly and the fresh air assembly are disposed side-by-side at the bottom of the base body; the turbid air component is provided with a turbid air cavity, the turbid air cavity is provided with a turbid air cavity inlet and a turbid air cavity outlet, the turbid air cavity inlet is communicated with the air outlet end of the second heat exchange air duct, and the turbid air cavity outlet is communicated with the outside;
indoor turbid wind in the second heat exchange air duct can enter the turbid wind cavity through the turbid wind cavity inlet and is discharged to the outside through the turbid wind cavity outlet.
5. The fresh air device of claim 4, wherein the base body defines a transition chamber defining a first transition chamber inlet, a second transition chamber inlet, and a transition chamber outlet; the first transition cavity inlet is communicated with the air outlet end of the second heat exchange air duct, the second transition cavity inlet is communicated with the room, and the transition cavity outlet is communicated with the turbid air cavity inlet;
when outdoor fresh air and indoor turbid air do not need heat exchange, the inlet of the first transition cavity is closed and the inlet of the second transition cavity is opened, so that the indoor turbid air enters the transition cavity through the inlet of the second transition cavity and is discharged to the outside through the turbid air cavity;
when outdoor fresh air and indoor turbid air need heat exchange, the inlet of the first transition cavity is opened and the inlet of the second transition cavity is closed, so that indoor turbid air enters the second heat exchange air duct and enters the transition cavity through the inlet of the first transition cavity, and then is discharged outdoors through the turbid air cavity.
6. The fresh air device of claim 5, further comprising a third wind deflector slidably disposed at the first transition chamber inlet and a fourth wind deflector that can open or close the first transition chamber inlet;
the fourth wind deflector is slidably arranged at the inlet of the second transition cavity, and the fourth wind deflector can open or close the inlet of the second transition cavity.
