LIQUID EJECTION HEAD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18604019 titled 'LIQUID EJECTION HEAD
The present invention is a liquid ejection head with multiple ejection ports, pressure chambers, and flow channels for supplying and collecting liquid.
- Multiple ejection ports for liquid ejection.
- Multiple pressure chambers for controlling liquid flow.
- Printing element substrate with supply and collection flow channels.
- Bypasses as flow channels that do not pass through pressure chambers.
- Bypasses include options for both supply and collection flow channels.
Potential Applications: - Inkjet printers - 3D printing - Bioprinting
Problems Solved: - Efficient liquid ejection - Precise control of liquid flow - Minimization of clogging
Benefits: - High-quality printing - Reduced maintenance - Improved printing speed
Commercial Applications: Liquid ejection heads can be used in various industries such as printing, manufacturing, and biomedical fields. The technology can enhance productivity and quality in these sectors.
Questions about liquid ejection heads: 1. How does the design of the liquid ejection head impact printing quality? 2. What are the potential challenges in implementing this technology in industrial settings?
Original Abstract Submitted
An embodiment of the present invention is a liquid ejection head, including: multiple ejection ports; multiple pressure chambers; a printing element substrate on which a printing element is arrayed in which a supply flow channel that extends in a direction in which the multiple pressure chambers are arrayed and that supplies the multiple pressure chambers with a liquid and a collection flow channel that extends in the direction and that collects the liquid from the multiple pressure chambers are provided; and at least two or more bypasses as flow channels that do not pass through the pressure chambers, in which the at least two or more bypasses include at least one of two or more bypasses for each supply flow channel and two or more bypasses for each collection flow channel.
