Document Type and Number:
WIPO Patent Application WO/2018/150640
Kind Code:
A1
Abstract:
Provided is a droplet jetting device that can be manufactured easily and inexpensively and that allows a small amount of liquid to be jetted with a high responsiveness and without being widely dispersed over the required flight distance. A droplet jetting device includes: a nozzle (10) to jet droplets; a detection means (9) for detecting a finger or an object in the flight path of the droplet jetted from the nozzle (10); a pump (P) having a suction unit to suction the liquid and a discharge unit that is connected to the nozzle (10) and discharges the liquid suctioned by the suction unit; a driving means for causing the liquid to be suctioned in by the pump (P) and compressing and discharging the suctioned liquid by way of rotating a cam (4); and a controlling means (C) for operating the driving means. The controlling means (C) operates the pump (P) by rotating the cam (4) and makes the liquid into droplets and jets same from the nozzle (10) when the detection means (9) detects a finger or an object.
