Abstract
An inflow opening of an inflow path opens to a space in a tank. An outflow opening of an outflow path opens to the space in the tank. The inflow opening and the outflow opening are vertically above a maximum level of the moisturizing liquid allowed to be stored in the tank.
Claims20
A liquid ejection apparatus comprising:
- a head comprising an ejection surface in which a plurality of ejection openings for ejecting liquid are formed;
- a tank configured to store moisturizing liquid;
- an inflow path which connects a space in the tank with an ejection space opposing the ejection surface, and configured to allow air flow from the ejection space towards the tank passing through the inflow path, an inflow opening of the inflow path opening to the space in the tank;
- an outflow path which connects the space in the tank with the ejection space, and configured to allow air flow from the tank towards the ejection space passing through the outflow path, an outflow opening of the outflow path opening to the space in the tank;
- and
- a ventilator configured to move the air in the inflow path to the space in the tank and to move the air in the outflow path to the ejection space, wherein:
- the inflow opening and the outflow opening are vertically above a maximum level of the moisturizing liquid allowed to be stored in the tank.
