Liquid Ejecting Apparatus Cooling via Displaced Air Intake

The patent divides the air intake system into multiple separate air introduction ports positioned at different locations within the housing, rather than using a single outside air introduction unit. This segmentation allows different regions of the housing to be cooled independently without creating disruptive airflows in the liquid ejection path.

The patent introduces air at specific locations (air introduction ports) that are strategically positioned to cool the liquid ejecting head and housing without creating airflows in the critical space between the liquid ejecting head and recording medium. This localised air introduction maintains cooling effectiveness while preserving ejection accuracy.

The patent combines the cooling function with the existing housing structure by incorporating air introduction ports directly into the housing. This merges the thermal management function with the structural component, eliminating the need for separate cooling systems or additional external units.

The housing structure itself serves the dual purpose of providing structural support and enabling thermal management through integrated air introduction ports. The system uses its own structural components to achieve cooling without requiring external dedicated cooling devices.
