The invention relates to an atomizer nozzle (10) with a liquid channel (19) which communicates downstream with an annular mixing chamber (26). A liquid (F) is supplied to the liquid channel (19) via a liquid connection (12). The atomizer nozzle (10) additionally has a gas connection (13) which is connected to a gas line system (28). Pressurized gas (L) is conducted to an outer injection channel (29) and an inner injection channel (34) via the gas line system. Each of the two injection channels (29, 34) opens into the annular mixing chamber (26) at a respective injection point (30, 35). The outer injection point (30) is provided on a radially outer mixing chamber wall, and the inner injection point (35) is provided on a radially inner mixing chamber wall. The inflowing liquid can thus be finely atomized using little pressurized gas (L) in the annular mixing chamber (26) and dispensed downstream of the annular mixing chamber via at least one outlet opening (40) in the form of a spray jet (S).

An aerosol device having a bowl with a bottom defining a drain, and a side wall extending from the bottom to a rim. A nozzle is disposed within the bowl. The nozzle defines a chamber and an outlet orifice directed toward the side wall of the bowl. The aerosol device includes a liquid container fluidly coupled to the nozzle via a first conduit having an outlet tip disposed within the chamber of the nozzle and a second conduit connecting a source of pressurized gas to the chamber of the nozzle. The outlet tip is in the form of a tube defining elongated slots communicating from inside the tube to outside the tube, the slots each having a width defined between two parallel tube surfaces. The aerosol device generates submicron liquid droplets, and is suitable for disinfecting porous articles in an enclosed volume.

The invention relates to a device for forming coatings on surfaces of a component, band-shaped material, or tool, in which at least one wire-shaped or band-shaped material (2.1 and/or 2.2) is used for forming the coating and that is/are connected to a direct electrical current source, wherein an electric arc is formed between wire-shaped materials (2.1 and 2.2) or between one wire-shaped or band-shaped material and one anode or cathode, wherein wire-shaped or band-shaped material (2.1 and/or 2.2) may be fed by means of a feed device; and melted and/or evaporated material of the wire-shaped or band-shaped material (2.1 and/or 2.2) flows, by means of a gas jet (3) of a gas or gas mixture, through an inlet into the interior of a chamber (4) that can be heated to a temperature that is at least equal to the evaporation temperature of the at least one material used for the coating or of the material with the highest evaporation temperature, and the material(s) completely evaporates and exits through at least one opening (5) present on the chamber (4) and impinges on the surface to be coated of the component or tool (6) for forming the coating.

A nebulizer device and a nozzle module are provided. The nebulizer device includes a nebulizer module, the nozzle module, and a control module. The nozzle module includes a main body unit and a guide unit. The main body unit can be detachably connected to the nebulizer module. The main body unit has a plurality of openings penetratingly formed therethrough, an accommodating space, and an output part, and the openings and the output part are in spatial communication with the accommodating space. The main body unit corresponds to an inner wall of the accommodating space and protrudes toward the accommodating space to form a plurality of guiding parts, and each of the guiding parts is adjacent to one of the openings. The guide unit is disposed in the accommodating space and has a recessed part. The control module can be detachably connected to the main body unit.

A matter displacement and mixing system having a mixing chamber for material to enter, and a vortex aperture that directs air into the mixing chamber at either a high velocity for violent shearing or lower velocity for gentle mixing. This would depend on the shape of the vortex aperture, or the pressure.

A spray device includes side-by-side spray tips that are spaced from one another at a distal end of the spray device. A first spray tip has a first fluid pathway defining a first flow area. The first fluid pathway has a first swirl chamber having an outer perimeter and flutes having inner ends that direct a first fluid into the outer perimeter of the first swirl chamber for rotating the first fluid in a circular pattern. A second spray tip has a second fluid pathway that defines a second flow area that is larger than the first flow area. The second fluid pathway has a second swirl chamber having an outer perimeter and flutes having inner ends that direct a second fluid into the outer perimeter of the second swirl chamber for rotating the second fluid in a circular pattern.
