Title:
LIQUID DISCHARGE HEAD, AND LIQUID DISCHARGE DEVICE HAVING THE SAME
Document Type and Number:
Japanese Patent JP2023174012
Kind Code:
A
Abstract:
To accurately detect an average temperature of liquid in a whole flow channel.SOLUTION: A printer includes a head 1 that has a flow channel member 21 formed with a manifold flow channel 11 extending in a first direction D1 and communicated with a plurality of individual flow channels 19, a piezoelectric actuator 22 fixed to a top face 21a of the flow channel member 21, and two temperature sensors 81, 82. The piezoelectric actuator 22 includes a high potential electrode having a plurality of individual parts, a plurality of branch parts and stem parts, and a low potential electrode having a plurality of individual parts, a plurality of branch parts and stem parts. The stem parts of the high potential electrode are positioned opposite to the stem parts of the low potential electrode relative to at least a part of the manifold flow channel in the first direction D1. The temperature sensors 81, 82 are arranged in the first direction D1 between the stem parts of the high potential electrode and the stem parts of the low potential electrode.SELECTED DRAWING: Figure 2
