LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18230285 titled 'LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS
Simplified Explanation
The liquid ejection head described in the patent application includes an ejection port for liquid, a liquid reservoir portion to supply the liquid, and a pressure adjustment chamber that communicates with the liquid reservoir portion. The pressure adjustment chamber has an elastic deformation portion that can change its inner volume based on gas pressure, and a support portion that supports the elastic deformation portion on the liquid reservoir portion. The area between the elastic deformation portion and the support portion is more rigid than the elastic deformation portion.
- Ejection port for liquid
- Liquid reservoir portion
- Pressure adjustment chamber with elastic deformation portion
- Support portion for elastic deformation portion
- Area with higher rigidity between elastic deformation portion and support portion
- Potential Applications
- Inkjet printers - 3D printers - Medical devices for precise liquid dispensing
- Problems Solved
- Maintaining consistent pressure for liquid ejection - Preventing leaks or spills - Ensuring accurate and controlled liquid dispensing
- Benefits
- Improved precision in liquid ejection - Reduced risk of malfunctions or clogs - Enhanced performance and reliability in liquid dispensing systems
Original Abstract Submitted
A liquid ejection head includes an ejection port configured to eject liquid, a liquid reservoir portion configured to supply the liquid to the ejection port, and a pressure adjustment chamber configured to communicate with the liquid reservoir portion. The pressure adjustment chamber includes an elastic deformation portion configured so that an inner volume thereof can be changed according to a gas pressure and a support portion configured to support the elastic deformation portion on the liquid reservoir portion. An area between the elastic deformation portion and the support portion has higher rigidity than the elastic deformation portion.
