Abstract

A liquid jet head includes: a head portion including a supply flow path configured to allow liquid supplied from the outside to flow therethrough, a pressure chamber communicating with the supply flow path, a driver element configured to drive the pressure chamber, and a nozzle communicating with the pressure chamber, the head portion being configured to eject liquid droplets through the nozzle; a circuit portion configured to supply a drive waveform to the driver element; and a cooling portion including a cooling flow path configured to allow the liquid to flow therethrough, the cooling portion being coupled and fixed to the circuit portion, wherein the liquid flows through the supply flow path and through the cooling flow path in parallel.

Description

technical field [0001] The present invention relates to a liquid ejection head and a liquid ejection device for recording by ejecting liquid droplets onto a recording medium. Background technique [0002] In recent years, liquid ejection heads of the ink ejection system have been used which eject ink droplets onto recording paper or the like to record characters or graphics, or eject liquid materials onto the surface of an element substrate to form a functional thin film. In this method, a liquid such as ink or a liquid material is guided from a liquid tank to a channel through a supply tube, pressure is applied to the liquid filled in the channel, and the liquid is ejected as droplets from a nozzle connected to the channel. When discharging liquid droplets, the liquid jet head or the recording medium is moved to record characters or graphics, or to form a functional thin film or three-dimensional structure of a predetermined shape. [0003] The liquid ejection head of the ...
