Title:
INJECTION NOZZLE AND LIQUID INJECTION DEVICE
Document Type and Number:
Japanese Patent JP2023022564
Kind Code:
A
Abstract:
To effectively clean the skin.SOLUTION: A liquid injection device includes: an injection nozzle 11 having a nozzle hole 1 through which to inject liquid 3; a pressurized liquid supply unit 27 for pressurizing liquid and sending the pressurized liquid to the injection nozzle; and a control unit 4 for controlling an operation of the pressurized liquid supply unit and flying the liquid injected through the nozzle hole in a state of being split into droplets 7 from a continuous flow 5. The liquid 3 has properties of 2.0-4.0 mPa s in viscosity and 10-50 mN/m in surface tension. The control unit controls supply pressure of the pressurized liquid supply unit 27 so that an injection velocity of the liquid injected from the injection nozzle is in the range of 10-80 m/s, and the number of droplets (number/s), which is the number of generated droplets 7 per second, is in the range of 0.40×105-9.5×105.SELECTED DRAWING: Figure 1
