LIQUID DISCHARGE HEAD AND METHOD OF MANUFACTURING THE LIQUID DISCHARGE HEAD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18188372 titled 'LIQUID DISCHARGE HEAD AND METHOD OF MANUFACTURING THE LIQUID DISCHARGE HEAD
Simplified Explanation
The patent application describes a liquid discharge head used in printing technology.
- The liquid discharge head consists of a recording-element substrate that discharges liquid, a cuboid-like liquid tank that supports the substrate and stores the liquid, and an absorbent material inside the tank that absorbs and holds the liquid.
- The bottom of the liquid tank has multiple projections.
- These projections are arranged in a way that surrounds or straddles the injection position where the liquid is injected into the absorbent using an injection needle.
Original Abstract Submitted
A liquid discharge head includes i) a recording-element substrate configured to discharge a liquid, ii) a cuboid-like liquid tank configured to support the recording-element substrate and to store the liquid to be discharged from the recording-element substrate, and iii) an absorbent accommodated in a compressed state in the liquid tank and configured to absorb and hold the liquid. In the liquid discharge head, multiple projections are formed on a bottom of the liquid tank. In addition, as viewed in plan in a direction orthogonal to the bottom, the projections are disposed so as to surround or straddle an injection position at which the liquid is injected into the absorbent using an injection needle.
