The invention relates to automated devices for pro¬ducing aerosols of liquid disinfectants and for spraying same. A mo¬bile hygiene unit comprises a housing (1) containing a disinfectant spraying unit (2) with a spraying nozzle (3), a tank (4) containing disinfectant, a compressor (5), and a control unit (6). It further com¬prises a mechanism for regulating the droplet size distribution of the aerosol, including a pump (7), an electromagnetic valve (8), and a dosing nozzle (9) with an internal cylinder. The disinfectant spraying unit (2) comprises a shaped nozzle (3) having a nozzle head (10) of axisymmetric cross-section attached thereto, and a mixing chamber (11) for mixing disinfectant with compressed air, having two thread¬ed inlets for a pneumatic line (12) and a hydraulic line (13), said inlets being arranged at an angle of 180°. The dosing nozzle (9) contains an internal cylinder and a rod with a threaded tip. The mobile hygiene unit generates an aerosol in four droplet size distribution modes: dry fog (from 3.5 to 10 pm), wet fog (from 10 to 30 pm), mist (from 30 to 50 pm), and spray (from 50 to 100 pm). The invention allows highly precise regulation of the droplet size distribution of the aerosol in each mode without the need to change the spraying nozzle.

A fog injection nozzle able to generate a swirling cone of fog. The nozzle includes an internal cavity into which a pressurized liquid and a pressurized gas are introduced. The pressurized liquid is introduced into the cavity via a central axial duct of a cylindrical block and the pressurized gas is introduced into the cavity via a plurality of axial through holes disposed about the central axial duct. The axial through holes and radial arms are arranged such that a mixture of the liquid and gas inside the cavity is asymmetrically deflected by the radial arms to cause a swirling tangential component to appear in the conical flow of fog discharged from the nozzle.

The invention relates to an aerosol device comprising:—a container containing:—one or more propellants, and—a composition comprising one or more sebum-absorbing powders with a sebum up-take of greater than or equal to 35 ml/100 g, it being possible for the propellant(s) to be present in the composition or, in the container, separate from the composition,—a means for dispensing said composition comprising:—a body (3) that is open at its two opposite axial ends,—an engaging part (10) that is open at its two opposite axial ends, at least partially defining a dispensing orifice (12).

A nozzle body and a method of forming the nozzle body. The nozzle body includes at least two hollow-cone nozzle geometries. The nozzle body includes an injection molded or a 3D printed thermoplastic material.

A nozzle includes a housing having an inner chamber, a first opening connected to the inner chamber, and a second opening connected to the inner chamber, and a solid, partially conical, plug in the second opening, the solid plug configured to leave a slit around the plug connected to the inner chamber, and the plug extending beyond an end of the housing.

A liquid ejecting head includes a nozzle. A sectional shape at a first-position in the nozzle in an ejection-direction is a first-external-shape, and a straight line extending in a second-direction orthogonal to both the ejection-direction and a first-direction being a longitudinal-direction of the first-external-shape and passing through a center of the first-external-shape in the first-direction is a first-center-line. A first-width corresponding to a maximum width in the second-direction in a portion of the first-external-shape on one side in the first-direction with respect to the first-center-line is at a third-position in the first-direction. A second-width corresponding to a maximum width in the second-direction in a portion of the first-external-shape on the other side in the first-direction with respect to the first-center-line is at a fourth-position in the first-direction. A distance between the third-position and the fourth-position is greater than the first-width and the second-width.

One variation of a system includes: a mount defining an inlet configured to couple to a water supply; a body defining a fluid circuit and coupled to the mount; and a pressure regulator interposed between the inlet and the fluid circuit and configured to regulate water supplied at the inlet over a range of inlet pressures to a range of internal pressures less than and narrower than the range of inlet pressures. A set of nozzles arranged on the body and coupled to the fluid circuit are configured to, in response to the pressure regulator regulating a first inlet pressure down to a first internal pressure, discharge water droplets: exiting the body with kinetic energies in a range of kinetic energies; exiting the body in a first spray pattern defining a first width at a target distance below the body, and exhibiting a first volumetric ratio of water to air.

A shower device for creating at least one water jet pattern with a structural assembly, with a nozzle assembly and with a lighting assembly. It is proposed that the structural assembly provides an exit opening for the emergence of the water discharged by the nozzle assembly and comprises an outer edge region running about the edge of the exit opening, that the exit opening during shower operation is only partially occupied with emerging water at any given time, that the nozzle assembly is arranged distributed along at least a portion of the edge of the exit opening at the edge region and that the path of the water discharged by the nozzle assembly during the shower operation runs each time from the edge region in the direction of the exit opening and then through the exit opening.
