Nozzle for spraying liquid in the form of mist

A nozzle for spraying a fluid, the nozzle being designed to be mounted on a dispensing container, said nozzle comprising:

• at least one fluid inlet capillary extending longitudinally along an axis A1,
• a turbulence chamber for receiving the fluid to be sprayed, said turbulence chamber has a maximum cross-section S and a maximum diameter-D,
• at least two conduits that extend longitudinally along said axis and being radially offset from said axis, said conduits in fluid connection with the inlet capillary,
• at least two turbulence channels, in fluid connection with said at least two conduits, and connecting said at least two conduits with the turbulence chamber, said at least two conduits thus connecting the inlet capillary to the at least two turbulence channels,
• a spray orifice supplied by the turbulence chamber, the spray orifice has axial symmetry and a constant cross-section s, said turbulence chamber has along the axis, a cross-section that decreases towards said spray orifice,
• wherein
• the ratio of the cross-sectional area s of the spray orifice to the maximum cross-sectional area S of the turbulence field is such that 1%≤S/S≤20%,
• the spray nozzle is operated by means of an actuator independent of the nozzle, and
• the inlet capillary has a cross-sectional area that allows a fluid shear rate greater than 5000 s−1.
