LIQUID DISCHARGE HEAD AND LIQUID DISCHARGE APPARATUS
This abstract first appeared for US patent application 20250115053 titled 'LIQUID DISCHARGE HEAD AND LIQUID DISCHARGE APPARATUS
Original Abstract Submitted
a liquid discharge head includes a discharge element substrate configured to discharge a liquid, an upstream-side flow path connected to the discharge element substrate and configured to supply a liquid to the discharge element substrate, a downstream-side flow path connected to the discharge element substrate and configured to collect a liquid from the discharge element substrate, and a pump connected to each of the upstream-side flow path and the downstream-side flow path and configured to cause a liquid within the downstream-side flow path to flow out to the upstream-side flow path, wherein the pump includes a pump outflow hole for causing the liquid within the downstream-side flow path to flow out to the upstream-side flow path, and wherein, in a use state of the liquid discharge head, an opening of the pump outflow hole faces upward in a substantially vertical direction.
