Title:
LIQUID JET DEVICE
Document Type and Number:
Japanese Patent JP2023130827
Kind Code:
A
Abstract:
To shorten a distance at which self-liquid is formed into liquid droplets, in jetting liquid at a high speed.SOLUTION: A liquid jet device 1 is equipped with a nozzle 27 that jets liquid 3, a liquid carriage pipe 7 through which the liquid 3 is carried to the nozzle 27, and a vibration generating part 40 that generates vibrations. The vibration generating part 40 contacts at least one of the liquid 3, the nozzle 27 and the liquid carriage pipe 7, where when the liquid 3 jetted from the nozzle 27 is formed into a plurality of liquid droplets 3b and then the liquid droplets scatter in a state where the vibration generating part 40 is not generating vibrations, and the number of the liquid droplets 3b passing through a predetermined position in a unit time is defined as frequencies at which self-liquid is formed into liquid droplets, frequencies of vibrations that are generated by the vibration generating part 40 are larger than the frequencies at which self-liquid is formed into liquid droplets.SELECTED DRAWING: Figure 2
