LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240208218 titled 'LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS

The liquid ejecting head described in the patent application includes a substrate with ejection openings for liquid, a flow-path member supporting the substrate, and a heating unit that heats the ejection region of the substrate.

The substrate has ejection openings for liquid ejection.
The flow-path member has a supply flow path and a collection flow path for liquid.
The heating unit heats the ejection region of the substrate.
The collection flow path is located on the side where the distance between the ejection region and a side of the substrate is longer.
The supply flow path is located on the side where the distance between the ejection region and a side of the substrate is shorter.

Potential Applications: - Inkjet printers - 3D printing - Bioprinting

Problems Solved: - Efficient liquid ejection - Precise heating of ejection region

Benefits: - Improved printing quality - Enhanced control over liquid ejection - Energy efficiency due to precise heating

Original Abstract Submitted

a liquid ejecting head includes: a substrate including ejection openings configured to eject liquid; a flow-path member supporting the substrate and having a supply flow path that supplies the substrate with liquid, on one side in a first direction intersecting the arrangement direction of the ejection openings and a collection flow path that collects liquid from the substrate, on the other side; and a heating unit that heats an ejection region including the liquid ejection openings in the substrate. on both sides of the ejection region of the substrate in the first direction, the collection flow path is located on a side where the distance between the ejection region and a side of the substrate in the first direction is longer and the supply flow path is located on a side where the distance between the ejection region and a side of the substrate in the first direction is shorter.
