Title:
LIQUID EJECTOR
Document Type and Number:
Japanese Patent JP2022041273
Kind Code:
A
Abstract:
To provide a liquid ejector which can supply liquid as droplets containing fine bubbles.SOLUTION: A liquid ejector 1 includes a pump 2 that can be mounted to a container 4 and an ejection head 3 capable of ejecting liquid L from the pump 2. The ejection head 3 includes an ejection hole 3a, a spin groove G3, and a tubular wall 31 that surrounds the ejection hole 3a and projects forward. The pump 2 is a pump that brings about suck-back in an internal space S31 of the tubular wall 31. The amount of suck-back VS generated by the suck-back is larger than volume V31 of the internal space S31.SELECTED DRAWING: Figure 1
