LIQUID DISCHARGE HEAD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18320240 titled 'LIQUID DISCHARGE HEAD

Simplified Explanation

The patent application describes a liquid discharge head that includes a channel member and an actuator member.

  • The liquid discharge head has multiple individual channels, each with a nozzle and a pressure chamber connected to the nozzle.
  • The channel member also has a communicating channel that connects all the individual channels.
  • The actuator member is placed on the surface of the channel member and has multiple actuators, each with individual electrodes.
  • The actuator member also has branched parts that connect the individual electrodes and a trunk part that connects the branched parts.
  • The trunk part of the actuator member has a contact for an electric power supply.
  • The communicating channel of the liquid discharge head overlaps with the trunk part of the actuator member.


Original Abstract Submitted

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