Abstract: The vaporization nozzle (1) is formed by a nozzle body (10) including a first pressurized gas intake perforation (11), and at least one second perforation (12) for intake of a liquid to be fractionated, in communication with the first perforation, and a liquid vaporization zone (13), formed in the axis of the first perforation (11). This nozzle is noteworthy in particular in that the or each intake perforation (12) of the liquid is in communication with the first perforation (11) through an underpressure chamber (15) that is formed between the first perforation and the vaporization zone, with the propellant gas stream passing all the way through the depression chamber (15).

Abstract: The cartridge (1) for dispensing an aerosol includes a liquid container (12), a nozzle (5) communicating with the container via a suction cannula (4) and a compressor (6) for producing a carrier stream of compressed air introduced into the nozzle such that the contents of the container are first sucked in, then fractionated and finally propelled into an expansion chamber (13) and then to the outside. The cartridge is remarkable in that the elements of which it consists form a non-dismountable assembly and includes electronic circuitry (9) of planned obsolescence capable of directly or indirectly determining the total quantity of liquid consumed during previous operation cycles, of comparing this value with a setpoint value representative of the quantity of liquid present in the container before the first use, and of preventing the subsequent operation of the compressor when the liquid contained in the container has been drained.

Abstract: The advertising panel is to display an advertising message and to diffuse a scent which is associated with the contents of the visually-displayed message. The inventive panel includes a parallelepiped volume containing: an assembly which is used to display an advertising message that is disposed opposite a display window, and at least one scent diffuser which is connected to a scent-diffusing element which is in turn installed opposite an opening in the panel, such as to diffuse a scented flow to the exterior. The diffusing element is connected to the head of the scent diffuser, thereby ensuring that a carrier gas is mixed with the scented fluid contained in the receptacle. The scented flow obtained at the outlet of the head is pulsed towards the diffusing element and, subsequently, to the exterior of the panel.

Abstract: The nebulisation device includes a liquid reservoir, a liquid supply line for supply of liquid to a nebulisation zone and an outlet opening from the nebulisation zone by which a flow of nebulised liquid particles escapes the nebulisation zone. The outlet opening opens into the liquid reservoir above the level of the liquid and the liquid reservoir has an escape opening for nebulised liquid particles, by which some of the nebulised liquid particles, coming from the outlet opening, leave the reservoir. Optionally, the device comprises an outside air inlet duct with a nozzle in the nebulisation zone and an opening to outside air in the liquid reservoir.

Abstract: The nebulisation venturi includes a liquid supply duct and compressed air supply duct, each duct having a nozzle opening in the nebulisation zone in which the air arriving under pressure from the supply duct nebulises the liquid coming from the liquid supply duct. The venturi includes a regulator for the relative position of the liquid supply duct nozzle with relation to the compressed air supply duct nozzle. The regulator can adjust at least the longitudinal position of the liquid supply nozzle and/or the angular position of the liquid supply nozzle. The venturi preferably includes a supply duct for free air with a nozzle in the nebulisation zone and an opening to the outside.

Abstract: A nebulizing attachment having a body with an open conical chamber formed therein. The body includes a nozzle with a sharp edge behind which a perforation is formed for supplying air under pressure. Another nozzle is provided in communication with the open conical chamber for supplying liquid therein. The liquid is sucked into the chamber by the effect of vacuum brought about by the passage of the air flow from the nozzle to an outlet therefor. The liquid is fractionated and mixed by the effect of turbulence in this chamber.
