开口面积的决定方法及液滴喷射装置
By determining the ρ0.45/σ value within the range of liquid density, surface tension, and viscosity, as well as the Reynolds index Re and the number of nozzles Je in the droplet jetting device, the problem of unsuitable nozzle orifice opening area was solved, enabling the liquid to be jetted in an optimal droplet state, thus improving cleaning or cosmetic effects.

AI Technical Summary
In existing droplet spraying devices, the opening area of the nozzle orifice is not of a suitable size, causing the liquid to be sprayed in a non-optimal droplet state, which affects the cleaning or beauty effect.
By determining the liquid density and surface tension, the ρ0.45/σ value is between 300 and 900, and the dynamic viscosity coefficient ν is between 1.0E-6 and 2.0E-5. Combined with the Reynolds index Re and the limit of the number of nozzles Je, the opening area S of the nozzle orifice is determined, so that the liquid jet is split into droplets.
It enables liquid to be sprayed in a preferred droplet state, ensuring that the jet stream splits into uniform droplets in smooth or wavy flow regions, thus improving cleaning or beauty effects.
