LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240109326 titled 'LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS

Simplified Explanation

The liquid ejection head described in the patent application includes a print element substrate with multiple ejection openings, pressure chambers, a common flow path, and pumps for circulating liquid. A flow path member is laminated to the print element substrate, with a supply flow path and a collection flow path for supplying and collecting liquid, respectively. The circulating pump generates a flow of liquid through the supply flow path, common flow path, and collection flow path.

• Print element substrate with multiple ejection openings, pressure chambers, common flow path, and pumps for liquid circulation.

Original Abstract Submitted

a liquid ejection head includes a print element substrate including multiple ejection openings, pressure chambers, a common flow path, and pumps, the pumps being configured to circulate liquid between the common flow path and the pressure chamber; and a flow path member laminated to the print element substrate. the flow path member includes a supply flow path and a collection flow path, the supply flow path being configured to supply liquid to the print element substrate, and the collection flow path being configured to collect liquid that is not ejected. the supply flow path and the collection flow path have liquid connection with the same common flow path. a circulating pump generates a flow of liquid flowing in an order of the supply flow path, the common flow path, and the collection flow path, the circulating pump being provided at a position different from the print element substrate.
