LIQUID EJECTION HEAD AND METHOD FOR MANUFACTURING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18152917 titled 'LIQUID EJECTION HEAD AND METHOD FOR MANUFACTURING THE SAME
Simplified Explanation
The patent application describes a liquid ejection head with a specific structure and two titanium oxide films. The first film has a contact angle of 40° or less with pure water and covers the inner walls of the flow path and liquid introduction flow path. The second film has a contact angle of 70° or more and partially covers the first film near the opening end.
- The liquid ejection head includes an ejection orifice for ejecting liquid and a flow path for the liquid to flow through.
- The flow path forming substrate supplies the liquid through a liquid introduction flow path.
- The first titanium oxide film has a contact angle of 40° or less with pure water and covers the inner walls of the flow path and liquid introduction flow path.
- The second titanium oxide film has a contact angle of 70° or more and partially covers the first film near the opening end.
Potential applications of this technology:
- Inkjet printers
- 3D printers
- Industrial printing systems
- Bioprinting
Problems solved by this technology:
- Improved liquid ejection performance
- Prevention of clogging or blockages in the flow path
- Enhanced durability and longevity of the liquid ejection head
Benefits of this technology:
- More precise and accurate liquid ejection
- Reduced maintenance and cleaning requirements
- Longer lifespan of the liquid ejection head
- Enhanced print quality and reliability
Original Abstract Submitted
A liquid ejection head has at least a structure including an ejection orifice forming member having an ejection orifice for ejecting a liquid and a flow path communicating with the ejection orifice and a flow path forming substrate having a liquid introduction flow path communicating with the flow path and supplying the liquid, and includes: a first titanium oxide film with a pure water contact angle of 40° or less; and a second titanium oxide film with a pure water contact angle of 70° or more, wherein the first titanium oxide film covers the structure including inner walls of the flow path and the liquid introduction flow path and is exposed in the flow path and the liquid introduction flow path, and the second titanium oxide film has a portion covering the first titanium oxide film in a vicinity of an opening end.
