The invention relates to a device for producing special effect fog, in particular in the field of stage technology, comprising fog generator (1) which is equipped with a heating element, wherein a fog fluid is evaporated by means of the heating element, and at least one ultrasonic vaporizer (5) which is arranged in a housing (2) on the bottom (3) of a main mixing chamber (4), wherein the fog which is generated by the fog generator (1) can be conducted into the main mixing chamber (4), and wherein, furthermore, a baffle wall (7) is provided in the main mixing chamber (4) close to an outlet opening (6). In addition, a pre-mixing chamber (8) is provided, into which an air stream which is generated by a fan (9) and the fog which is generated by the fog generator (1) can be introduced via respective access openings (14, 15). The pre-mixing chamber (8) is connected by means of a transfer opening (10) to the main mixing chamber (4), wherein the transfer opening (10) is arranged in the main mixing chamber (4) so as to lie opposite the baffle wall (7).

A boom for a sprayer vehicle includes a fluid-carrying medium; at least one nozzle fluidly coupled to the fluid-carrying medium; and at least one unmanned aerial vehicle tethered to the fluid-carrying medium. The at least one unmanned aerial vehicle includes a plurality of fans, and the nozzle is arranged to discharge material through a fan. Related methods and sprayer vehicles are also disclosed.

A scent adjustment system includes a scent emitter arranged to supply a scent material to a target space, a storage, and a controller. The storage stores sensory information in which an intensity of a smell of the scent material perceived by a person and a concentration of the scent material are associated with each other. The controller adjusts the concentration of the scent material supplied from the scent emitter based on the sensory information stored in the storage.

An apparatus, system, and method for providing a non-linear fluid stream into an environment for cooling purposes are disclosed. Such an apparatus includes a body portion and a nozzle, the nozzle being adapted to direct water into the environment. Such an apparatus may include a body portion having a flow channel defined therein for gas flow therethrough; and, a nozzle operatively disposed within the flow channel; said nozzle adapted to direct a liquid therefrom; wherein the channel and the nozzle are operatively disposed relative to each other so that a gas flowing through the channel and the liquid are combined into a fluid stream directed from the apparatus into the surrounding environment.

An atomizer and a humidity controller that are able to separate water with high atomization efficiency are provided. The atomizer includes: a housing that includes an intake port and a discharge port; an ultrasonic wave generating unit that irradiates at least some hygroscopic liquid stored in the housing and containing a hygroscopic substance with ultrasonic waves and generates atomized droplets containing moisture; and an adjustment unit that adjusts relative humidity to reduce a vapor pressure determined in accordance with the relative humidity to less than a saturated vapor pressure of the hygroscopic liquid in at least a portion of a gas-liquid interface in an inner space of the housing.

There is described a fire-fighting apparatus comprising a housing comprising an upstream air inlet and a downstream fire-extinguishing stream outlet and a hollow body therebetween, wherein the housing houses an air stream traveling at high velocity; and a spray assembly concentrically mounted to the housing. The spray assembly comprises a fluid inlet connected to a source of fluid outside the housing; and a plurality of injecting assemblies fluidly connected to the fluid inlet and designed for breaking down an inflow of the fluid into droplets and projecting the droplets of the fluid within the air stream in a multiphase fire-extinguishing stream. The injecting assemblies each comprises a fluid outlet; a base plate through which extends the fluid outlet; a holding structure mounted to the base plate and extending downstream therefrom, and a unibody jet-fragmenting device mounted to the holding structure facing the stream of fluid exiting the fluid outlet.

An anti-condensation housing includes a connector to connect to a diffusing head configured to nebulize a product to diffuse. The housing includes a conduit having an inlet for a nebulized product, an outlet opening at a diffusing end, of the conduit, a fan at an insufflating end of the conduit. The fan generates a flow of air between the insufflating end and the diffusing end of the conduit. An internal surface of the conduit extending along a direction perpendicular to the direction of the air flow creates an obstacle for the progress of the air flow in the conduit. A retainer to retain the nebulized product stopped by the internal surface. A device to diffuse a product implementing the anti-condensation housing and a method for diffusing a product using such a device are provided.

Disclosed is a compact spraying module for spraying a liquid in the form of droplets for treating a target. The module includes a spraying unit including a nozzle containing at least one spraying member and a fan that is capable of generating a carrying air flow in the nozzle and of carrying the droplets originating from the member to the target. The module includes its own liquid supply system that and includes an electric pump, an electronic control and monitoring unit, a holder that keeps the pump near the spraying unit, an individual communication interface, and a power supply interface. Also disclosed is a system for spraying and controlling a plurality of such modules and to a method for controlling modules of such a system.
