Air intake switching device for portable air conditioner

Abstract

An air intake switching device for a portable air conditioner has a housing with multiple grid holes, at least one switching panel being mounted on the housing and at least one switching assembly being slidably mounted between the housing and the switching panel. The switching assembly drives the switching panel to slide relative to the housing to selectively allow the airflow passing through the housing. Therefore, the portable air conditioner is switched to perform an interflow air cycle or an independent air cycle between indoors and outdoors. A heat dissipating effect of the interflow air cycle and a cooling effect of the independent air cycle between indoor air and outdoor air are ensured.
