Abstract

The diffuser consists of a centrifugal fan (4) with a central tip (1) projecting inside the end of a supple capillary tube fed by a variable output dosing pump (5). The intake side of the pump is connected via a hollow needle to a reservoir (6) containing the perfume. The fan can have a porous disc (3) on one side to favour the diffusion of certain perfumes, and the diffuser can be fitted inside a housing (8) with an intake at the bottom, fitted with a filter (9), and an outlet (10) at the top.

Description

La présente invention concerne un dispositif permettant de diffuser un parfum dans un local. The present invention relates to a device for diffusing a perfume in a room.

La diffusion actuelle d'un parfum dans un local est réalisée suivant plusieurs procédés ; un principe couramment utilisé consiste à réaliser une pulvérisation mécanique en faisant passer le liquide mis sous pression par une pompe ou contenu dans un réservoir sous pression ) dans un orifice de petit diamètre de façon à fragmenter le débit en fine particules , un brasseur d'air ( ventilateur assurant la diffusion du parfum dans le local. Les systèmes à pulvérisation de liquide sous pression ne pouvant réguler leur débit ( la baisse de pression diminuant de beaucoup l'effet de fragmentation du liquide ) l'ajustement du débit ne pouvant être obtenu qu'avec un fonctionnement séquentielle ( 10 secondes de pulvérisation , 10 secondes d'arrêt par exemple) . The current diffusion of a perfume in a room is carried out according to several processes; a commonly used principle consists in carrying out a mechanical spraying by passing the liquid pressurized by a pump or contained in a pressurized tank) in a small diameter orifice so as to fragment the flow into fine particles, an air mixer (fan ensuring the diffusion of the perfume in the room. The systems with spraying of liquid under pressure cannot regulate their flow (the drop in pressure decreases by a lot the effect of fragmentation of the liquid) the adjustment of the flow can only be obtained '' with sequential operation (10 seconds of spraying, 10 seconds of stop for example).

la quantité minimum de parfum nécessaire au parfumage d'un local moyen ( 60 m3 ) nécessite un débit de parfum de 0.5 mm 3 seconde ; il est bien évident que si l'on cherche à pulvériser un débit aussi petit ,il sera nécessaire de passer par un venturi ou un ajutage extrêmement faible difficilement réalisable ) et disposer pour avoir l'action de pulvérisation d'une pression amont importante et par conséquent d'une pompe coûteuse . Le fonctionnement séquentiel génère des taux de saturation différents dans l'air et des variations olfactives désagréables( essentiellement duent à la discontinuité du débit . the minimum quantity of perfume necessary for perfuming an average room (60 m3) requires a perfume flow of 0.5 mm 3 seconds; it is quite obvious that if one seeks to spray such a small flow rate, it will be necessary to go through a venturi or an extremely small nozzle which is difficult to achieve) and have a large upstream pressure to have the spraying action and consequence of an expensive pump. The sequential functioning generates different saturation rates in the air and unpleasant olfactory variations (essentially due to the discontinuity of the flow.

De plus la plage de réglage de ces dispositifs est faible car pour éviter les défauts décrits ci-dessus ont ne peut espacer trop les impulsions . Une autre gamme de diffuseurs est constituée sur le principe du trempage d'un élément poreux ( papier ou élément tissé ) dont une extrémité est immergée dans le parfum et dont la partie émergée est située dans l'air du local à parfumer ; le parfum se déplace à l'extérieur du flacon par capillarité et la diffusion dans le local est réalisée par de l'air pulsé ou de la convection naturelle . Les défauts de ces produits proviennent des variations des tensions de vapeur des différents constituant ; les plus visqueux saturant rapidement les mèches ce qui dénature les parfums . Le dispositif selon l'invention permet de remédier à ces inconvénients. In addition, the adjustment range of these devices is small because, to avoid the faults described above, the pulses cannot be spaced too far apart. Another range of diffusers is based on the principle of soaking a porous element (paper or woven element), one end of which is immersed in the perfume and the emerged part of which is located in the air of the room to be perfumed; the perfume moves outside the bottle by capillary action and the diffusion in the room is carried out by forced air or natural convection. The defects of these products come from variations in the vapor pressures of the various constituents; the most viscous quickly saturate the wicks which distorts the perfumes. The device according to the invention overcomes these drawbacks.

Ce dispositif est constitué de 3 éléments . This device consists of 3 elements.

une pompe (5) munie d'une canne d'aspiration (11 ) , dans une version préférentielle de l'invention , la canne d'aspiration peut être constituée d'une tubulure pointue ( seringue ) dont la résistance mécanique permettra de traverser un opercule constitué d'un matériau souple( caoutchouc ) par exemple ; l'avantage de ce procédé réside dans la facilite et la propreté de la mise en oeuvre pour permettre le remplacement d' un flacon . L'opérateur âpres avoir retiré l'opercule de protection mécanique de la membrane devra perforer la membrane souple avec l'aiguille (11) ; la souplesse de la membrane assurera l'étanchéité entre l'intérieur du flacon et l'extérieur.  a pump (5) provided with a suction rod (11), in a preferred version of the invention, the suction rod can be constituted by a pointed tube (syringe) whose mechanical resistance will allow it to pass through a cover made of a flexible material (rubber) for example; the advantage of this process lies in the ease and cleanliness of the implementation to allow the replacement of a bottle. The operator after having removed the mechanical protection cover from the membrane must perforate the flexible membrane with the needle (11); the flexibility of the membrane will seal between the inside of the bottle and the outside.

Cette canne aspirante (11) sera reliée à une pompe doseuse ( 5) a débit variable ; cette variation permettra d'ajuster la quantité de liquide nécessaire au parfumage du local et ce de façon continue . De même le diffuseur ( 4) ( ventilateur ) disposera d'un variateur de vitesse de façon a adapter le brassage au volume du local pour obtenir une diffusion homogène. Le dispositif objet de l'invention consiste a réaliser un diffuseur capable d'écouler de tout petits débits et de les disperser en phase vapeur dans le local. This suction rod (11) will be connected to a metering pump (5) with variable flow; this variation will make it possible to adjust the quantity of liquid necessary for perfuming the room and this continuously. Likewise the diffuser (4) (fan) will have a speed variator so as to adapt the mixing to the volume of the room to obtain a homogeneous diffusion. The device which is the subject of the invention consists in producing a diffuser capable of draining very small flows and of dispersing them in the vapor phase in the room.

Les pompes doseuses en continue du commerce sont capable de réaliser les débits souhaités mais si l'on place un capillaire alimenté par une de ces pompes au dessus de l'axe d'un ventilateur , il se fonnera au bout du capillaire une goutte qui tombera sur le ventilateur et qui sera mécaniquement centrifugée en phase liquide au moins pour une partie du volume de la goutte. La présente invention consiste pour éviter ce phénomène a placer au centre de rotation de la turbine du ventilateur ( zone en dépression ) un axe ( 1 ) perpendiculaire a la turbine (4) du ventilateur dans une version préférentielle de l'invention cet axe ( 1 ) se raccordera a la turbine ( 4 ) par un rayon ; le diamètre de l'axe (1) dans sa partie supérieure sera réalisé de telle dimension qu'il permette l'introduction dans un tuyau capillaire souple ( 2 ) fig 2 en ménageant entre les deux pièces (1) et (2) un jeu suffisant pour qu'un film de liquide puisse s'écouler le long de l'axe (1) sans aucune formation de gouttes , puis par centrifugation le film liquide diminuera en épaisseur au fiu et a mesure ou il augmentera en surface ( éloignement de l'axe par centrifugation due a la rotation du disque formant la turbine (4) ) la vitesse relative dans l'air ventilé de ce disque croissant avec le rayon favorisera l'évaporation des fractions les moins volatiles.Commercial continuous metering pumps are capable of achieving the desired flow rates, but if a capillary supplied by one of these pumps is placed above the axis of a fan, a drop will form at the end of the capillary. on the ventilator and which will be mechanically centrifuged in the liquid phase at least for part of the volume of the drop. The present invention consists in avoiding this phenomenon by placing an axis (1) perpendicular to the turbine (4) of the fan at the center of rotation of the fan turbine (depression zone) in a preferred version of this invention this axis (1 ) will be connected to the turbine (4) by a spoke; the diameter of the axis (1) in its upper part will be made in such a dimension that it allows the introduction into a flexible capillary pipe (2) fig 2, leaving a clearance between the two parts (1) and (2) sufficient for a film of liquid to flow along the axis (1) without any formation of drops, then by centrifugation the liquid film will decrease in thickness with the oil and as or it will increase in surface (distance from the 'axis by centrifugation due to the rotation of the disc forming the turbine (4)) the relative speed in the ventilated air of this disc increasing with the radius will promote the evaporation of the least volatile fractions.

L'usure de l'axe (1) ou du capillaire (2) sera très faible , d'abord parce que la vitesse périphérique de l'axe (1) sera très faible le diamètre de l'axe étant de quelques dixièmes de millimètres , de plus les parfums étant composés d'huiles essentielles ces dernières assureront le refroidissement et la lubrification du couple de frottement . The wear of the axis (1) or of the capillary (2) will be very low, firstly because the peripheral speed of the axis (1) will be very low, the diameter of the axis being a few tenths of a millimeter , moreover the perfumes being composed of essential oils the latter will ensure the cooling and the lubrication of the friction torque.

Dans une version préférentielle de l'invention et pour certain type de parfums un disque poreux (3) ( papier ou carton ) pourra avantageusement être placé sur le disque de la turbine entre l'axe (1) et l'intérieur de la zone (4) ou seront situées les aubes (7) de la turbine de façon a ce que sa capillarite répartisse mieux encore le parfum et limite les risques de centrifugation de gouttelettes. In a preferred version of the invention and for certain types of perfumes, a porous disk (3) (paper or cardboard) can advantageously be placed on the turbine disk between the axis (1) and the interior of the zone ( 4) where the blades (7) of the turbine will be located so that its capillarite better distributes the perfume and limits the risk of centrifugation of droplets.

L'invention est caractérisée en ce que le réservoir de parfiun ( 6 ) sera préférentiellement situé au dessus de la pompe (5) de façon a ce que cette dernière soit en charge . caractérisée en ce la pompe ( 5) soit située entre le réservoir ( 6 ) et le ventilateur ( 4) de façon a ce que la perte de charge de la pompe (5) soit la plus faible possible . The invention is characterized in that the perfume tank (6) will preferably be located above the pump (5) so that the latter is loaded. characterized in that the pump (5) is located between the reservoir (6) and the fan (4) so that the pressure drop of the pump (5) is as low as possible.

Caractérisée en ce que le disperseur (4) ventilateur soit situé sous la (5) de façon a ce que la tuyauterie capillaire (2) alimentant l'axe (1) situé au centre de la turbine (4) soit la plus courte possible. Characterized in that the disperser (4) fan is located under (5) so that the capillary piping (2) supplying the axis (1) located in the center of the turbine (4) is as short as possible.

Caractérisé en ce que l'ensemble du dispositif soit placé dans une enveloppe (8) comportant a sa partie inférieure un filtre d'entrée d'air (9) et à sa partie supérieure une protection mécanique (10 ) assurant le rôle de diffuseur d'air. Characterized in that the entire device is placed in an envelope (8) comprising at its lower part an air inlet filter (9) and at its upper part a mechanical protection (10) ensuring the role of a diffuser 'air.
