LIQUID EJECTION HEAD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18397115 titled 'LIQUID EJECTION HEAD

The liquid ejection head described in the patent application consists of a printing element substrate with two arrays of ejection orifices and a protective member with corresponding openings.

• The printing element substrate has a first ejection orifice array and a second ejection orifice array, arranged in different directions.
• The protective member is positioned adjacent to the printing element substrate, separated by an adhesive layer.
• The protective member has a first opening for the first ejection orifice array and a second opening for the second ejection orifice array.

Potential Applications: - This technology can be used in inkjet printers for precise and efficient liquid ejection. - It may find applications in industrial printing processes that require high-quality output.

Problems Solved: - Prevents damage to the ejection orifices on the printing element substrate. - Ensures the accuracy and reliability of liquid ejection in printing devices.

Benefits: - Improved longevity and performance of liquid ejection heads. - Enhanced print quality and consistency in printing applications.

Commercial Applications: Title: Advanced Liquid Ejection Head Technology for Inkjet Printers This technology can be utilized in the manufacturing of high-speed inkjet printers for commercial printing businesses. It offers improved efficiency and print quality, making it a valuable asset in the printing industry.

Questions about Liquid Ejection Head Technology: 1. How does the protective member prevent damage to the ejection orifices? - The protective member acts as a barrier between the printing element substrate and external factors, safeguarding the ejection orifices from potential harm. 2. What are the key advantages of having two arrays of ejection orifices in the liquid ejection head? - The two arrays allow for more precise control and distribution of liquid, enhancing the overall performance of the printing device.

Original Abstract Submitted

A liquid ejection head according to the present disclosure includes: a printing element substrate including an ejection surface provided with a first ejection orifice array in which an ejection orifice configured to be capable of ejecting a liquid is arranged in plurality in an array direction and a second ejection orifice array arranged in a direction intersecting with the array direction and the first ejection orifice array; and a protective member provided with a first opening corresponding to the first ejection orifice array and a second opening corresponding to the second ejection orifice array, wherein the protective member is arranged adjacent to the ejection surface of the printing element substrate via an adhesive arranged between the first ejection orifice array and the second ejection orifice array.
