LIQUID DISCHARGE HEAD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18320249 titled 'LIQUID DISCHARGE HEAD

Simplified Explanation

- The patent application describes a liquid discharge head that includes individual channels with nozzles and pressure chambers. - The head also includes an actuator member with actuators that overlap with the pressure chambers in a perpendicular direction. - The actuator member has individual electrodes, branched parts connecting the electrodes, and a trunk part with a contact for an electric power supply. - The liquid discharge head also has a separate cooling channel where a cooling liquid flows. - The cooling channel includes a part that overlaps with the trunk part of the actuator member in the perpendicular direction.

Original Abstract Submitted

There is provided a liquid discharge head including: a channel member having individual channels, each of the individual channels including a nozzle and a pressure chamber communicating with the nozzle; and an actuator member arranged on a surface of the channel member and having actuators each of which overlaps with the pressure chamber of one of the individual channels in a first direction orthogonal to the surface, the actuator member including individual electrodes constructing the actuators, branched parts each connecting individual electrodes of the individual electrodes, and a trunk part connecting the branched parts and provided with a contact with respect to an electric power supply part. A cooling channel which is independent from the individual channels and in which a cooling liquid flows is formed in the liquid discharge head. The cooling channel has a first part overlapping with the trunk part in the first direction.
