LIQUID EJECTION HEAD SUBSTRATE AND LIQUID EJECTION HEAD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18530728 titled 'LIQUID EJECTION HEAD SUBSTRATE AND LIQUID EJECTION HEAD
The patent application describes an object that prevents a decrease in gas barrier properties when the cavitation resistance layer becomes thin in a liquid ejection head substrate.
- The substrate includes a heating element layer, an electric wiring layer, an insulative layer, and a metal layer that generates an electrochemical reaction with the liquid.
- The metal layer has different crystal particle diameters on each side, enhancing its performance.
- This innovation aims to maintain the barrier properties of the substrate even with a thin cavitation resistance layer.
Potential Applications:
- This technology can be used in inkjet printers, 3D printers, and other liquid ejection devices.
- It can also be applied in medical devices that require precise liquid ejection.
Problems Solved:
- Prevents reduction in gas barrier properties due to thin cavitation resistance layers.
- Enhances the performance and durability of liquid ejection heads.
Benefits:
- Improved efficiency and reliability of liquid ejection systems.
- Extended lifespan of liquid ejection heads.

Commercial Applications:
- Inkjet printer manufacturing industry.
- Medical device manufacturers requiring precise liquid ejection systems.
Questions about the Technology: 1. How does the different crystal particle diameters on the metal layer contribute to its performance? 2. What are the specific challenges faced by liquid ejection systems that this technology addresses?
Frequently Updated Research: There may be ongoing research on improving the materials and design of liquid ejection head substrates to further enhance their performance and durability.
Original Abstract Submitted
An object is suppressing the reduction in the gas barrier property in a case where the cavitation resistance layer becomes thin. An embodiment of the present invention is a liquid ejection head substrate, including: a first layer that forms a heating element that generates heat energy to eject a liquid; a second layer that functions as an electric wiring connected with the heating element; a third layer that is insulative and covers the first layer and the second layer; and a fourth layer that is a layer arranged over the third layer so as to cover at least the heating element, formed of metal, and to generate an electrochemical reaction with the liquid, in which a first average crystal particle diameter on a side that is in contact with the liquid and a second average crystal particle diameter on a side of the third layer are different.
