Abstract
A liquid consuming device includes a liquid container, an air tank, a liquid tank, and an ejection head. The liquid container is connectable to the air tank and the liquid tank. The air tank includes: an air flow path; an air chamber configured to communicate with a first storage chamber of the liquid container through the air flow path; and a first air communicating portion. The liquid tank includes: a liquid flow path; a second storage chamber configured to communicate with the first storage chamber through the liquid flow path; a liquid outlet port to allow liquid in the second storage chamber to flow out therefrom; and a second air communicating portion. The air flow path is configured to provide communication between the first storage chamber and the air chamber in a state where the liquid container is connected to the air tank and the liquid tank.
