Motion transmitting structure for a nozzle arrangement of a printhead chip for an inkjet printhead
First Claim
1. A printhead chip for an inkjet printhead, the printhead chip comprisinga substrate;
- and a plurality of nozzle arrangements positioned on the substrate, each nozzle arrangement comprising a nozzle chamber structure that defines a nozzle chamber in which ink is received;
an ink-ejecting member that is positioned in the nozzle chamber and is displaceable in the nozzle chamber to eject ink from the nozzle chamber;
at least one actuator that is positioned on the substrate, the, or each, actuator having a working portion that is displaceable with respect to the substrate when the actuator receives a driving signal;
a sealing structure that is positioned on the substrate and is interposed between the, or each, actuator and the ink-ejecting member to inhibit a passage of ink between the ink-ejecting member and the actuator; and
a motion transmitting structure that bridges the sealing structure, the motion transmitting structure interconnecting the working portion of the actuator and the ink-ejecting member so that displacement of the working portion relative to the substrate is transmitted to the ink-ejecting member.

Abstract
A printhead chip for an inkjet printhead includes a substrate. A plurality of nozzle arrangements is positioned on the substrate. Each nozzle arrangement includes a nozzle chamber structure that defines a nozzle chamber in which ink is received. An ink-ejecting member is positioned in the nozzle chamber and is displaceable in the nozzle chamber to eject ink from the nozzle chamber. At least one actuator is positioned on the substrate, the, or each, actuator having a working portion that is displaceable with respect to the substrate when the actuator receives a driving signal. A sealing structure is positioned on the substrate and is interposed between the, or each, actuator and the ink-ejecting member to inhibit a passage of ink between the ink-ejecting member and the actuator. A motion transmitting structure bridges the sealing structure. The motion transmitting structure interconnects the working portion of the actuator and the ink-ejecting member so that displacement of the working portion relative to the substrate is transmitted to the ink-ejecting member.
