Liquid discharge head, liquid discharge device, and liquid discharge apparatus
摘要:
A liquid discharge head includes a plurality of nozzles from which liquid is discharged, a plurality of individual-liquid-chambers communicating with the plurality of nozzles, respectively, a plurality of individual-drainage-channels communicating with the plurality of individual-liquid-chambers, respectively, a drainage-side common-liquid-chamber communicating with each of the plurality of individual-drainage-channels, a filter having filter holes and disposed between the plurality of individual-drainage-channels and the drainage-side common-liquid-chamber, and an intermediate-drainage-channel disposed between the filter and the plurality of individual-drainage-channels. The intermediate-drainage-channel faces the filter and communicates with two or more of the plurality of individual-drainage-channels. A cross-sectional area of the intermediate-drainage-channel is greater than a cross-sectional area of each of the plurality of individual-drainage-channels communicating with the intermediate-drainage-channel in a direction perpendicular to a direction of liquid flow.
