Definitions

• the present invention relates to the diffusion of volatile product which may consist of components, odorant, deodorant, bactericide, insecticide intended to treat the ambient air of a passenger compartment.
• the invention relates more particularly to an apparatus - provided with means for dosing the regeneration - of an absorbent substrate, in relation to the required volatilization, so as to provide either slow diffusion for constant treatment, or to be able to provide at any time a higher dose suitable for rapid treatment.
• the invention describes several variants, intended for different diffusers comprising an absorbent substrate and means for controlling its regeneration.
• US Patent No. 3,412,907 describes a housing formed by two perforated concave discs, containing a material impregnated with aromatic product, by compressing the discs the air laden with volatile product is expelled.
• Patent of the United States of America n ° 06174326 1980 filed in France under n ° 2.487.689 describes a dispenser which can immediately deliver a dose of volatile substance, the base forms a bellows surmounted by a box containing an element impregnated with volatile substance.
• the action of the pulsed air is only valid insofar as the device can release a certain quantity of volatile product. Since the impregnated materials have a very limited period of effectiveness, subject to ventilation, it goes without saying that the time of effectiveness will further decrease.
• the devices cited have little or nothing in common with the description in this document, except that they distribute products for the treatment of ambient air. In fact, they differ from the fact that they do not include any means for regenerating the impregnation of their absorbent material.
• English patent n ° 1,544,410 describes an odorous device intended to be suspended, it comprises a box inside of which is a capsule which must be perforated with a pin so that the solution is spilled on an absorbent material. A threaded element compresses the capsule to increase the flow of the product.
• This device has no flow control, and once the reserve is perforated, it is no longer possible to interrupt the flow, the diffusion is very irregular and this results in a limited duration of effectiveness.
• the Japanese patent 55.98.460 filed in France under the number 2.486.402 describes a device emitting perfume. It includes a reservoir placed above a spongy material which permeates after having perforated the reserve. This device does not make it possible to adjust the liquid flow rate, the adjustment then takes place by a flap which modifies the evaporation of the absorbent material.
• French patent 1,316,894 from 1962, describes a diffuser formed by a perfume bulb and an absorbent product enveloped by a relatively rigid material.
• This diffuser is found on the market, it consists of a cardboard support provided with a perforable bulb which impregnates a felt. It does not have a flow adjustment, nor a means to interrupt the flow of the liquid. Once perforated, it continues to flow, which produces an irregular and uncontrollable diffusion. At the start, the level being high, saturation occurs and thereafter too low a clearance, this results in a limited duration of effectiveness.
• the patent also provides, in a variant, for adjusting the height of the orifice relative to the level of the perfume, however, no usable technical indication is given, resulting in an adjustment capable of operating.
• the bulb is rotatably mounted in a circular opening, which distances the specialist from the solution according to the invention described in this document.
• the bulb is not limited in its rotation, it can perform several revolutions, not having an index, it is therefore impossible to locate the position of the orifice, which makes the adjustment device unfit for a rEi fOnctionement.
• the Japanese utility model ⁇ ° 10700/80 - 104435/80 - 10699/80 - 122736/80 describe containers which allow the evaporation of a solution from a wick which plunges directly into the product.
• Japanese utility models 59638/80 and 70962/73 describe devices fitted with a flexible container which must be compressed to transmit the solution to an absorbent material. These devices must include flexible containers which require the use of plastic material incompatible with the conservation of most aromatic products and these devices do not allow a rational dosage of impregnation or volatilization.
• Japanese Patent 74830/81 - 71915/81 - 71916/81 filed in France under No. 2506173 describes a container product ev 'aporable, they comprise an absorbent material impregnated with the solution which is dispensed dropwise by a capillary siphon, which must be primed by actuating a device which creates a depression.
• This device has several disadvantages, once the impregnation begins, the user may forget it, it will result in saturation, or even an overflow of the product.
• the apparatus designed for continuous impregnation must provide a very reduced flow rate, which requires a siphon with a very small capillary orifice and products of a well-defined viscosity. The majority of the products used tend to form a deposit which obstructs the orifices of small section, when they are not distributed by means of propulsion. The principle of priming the siphon and the capillary difficulties do not ensure reliable distribution, moreover this device cannot immediately deliver a larger dose.
• There are also known devices which diffuse volatile products with the cooperation of either heating or ventilation these devices are not mentioned since their design and their applications are very different from those of the present invention, which aims to remedy the disadvantages mentioned.
• the object is achieved according to the present invention by creating a volatile product diffuser provided with a modular regeneration substrate.
