In order to ensure that the air is blown out from the secondary air inlet 221 and the secondary air outlet 222, the cross-sectional area of the secondary air inlet 221 is smaller than that of the secondary air outlet 222.
Specifically, in some embodiments, the secondary intake vent 221 is used to communicate indoor air.
