FR2522270A1 - Vaporiser for diffusing perfume, deodorant etc. into atmos. of room - at rate increased by exposing additional porous diffuser discs - Google Patents

Abstract

The vaporiser comprises a vertical cylindrical reservoir to contain a liq. to be evaporated. A push-fit support can be moved up and down inside the reservoir; the support carrying a set of spaced, porous discs, esp. felt discs. A capillary-action wick extends through all the discs to project below the lowest disc. The top of the support is fixed to a cover which closes the top of the reservoir when the set of discs is pushed down inside the reservoir. The support pref. comprises a ring of vertical rods which surround the discs. A vertical guide bar pref. rises coaxially from the base of the reservoir to slide within a vertical guide tube extending down from its attachment to the cover fixed on top of the support. The vapour can be a perfume, a deodorant, a disinfectant etc. The rate of diffusion is immediately adjustable between zero and full capacity, simply by manually moving the cover up or down complete with diffuser discs.

Description

Device for atmospheric diffusion
of a product.

The present invention relates to a device for the
diffusion into the atmosphere, by evaporation, of a product by
example of a sanitation, deodorization or perfume product.

The device according to the invention is characterized in that it comprises a container or reservoir intended to contain the
liquid to evaporate, a support which is mounted vertically movable
relative to the container and carries a series of discs made of porous material, for example felt, spaced from each other and
can engage in the container, a wick which passes through the
looks like discs and the lower end of which protrudes by
relative to these, and a cover which is integral with the part
top of the holder and can close the container opening when
all the discs are in this one.

 The container is partly filled with liquid to be diffused.

When the support is in the low position, the wick plunges into the
liquid so that it rises in the wick by capillary action
and goes into the discs; but no diffusion takes place because the lid closes the container. Then simply raise the support
to bring all or part of the discs into the atmosphere in
which liquid should be dispensed; diffusion is thus re
glable. Discs automatically recharge with liquid when
that the support is returned to the low position during the periods
of non-use.

The set of discs is advantageously surrounded by
a protective cage.

The support can consist of a diameter disc
higher than the container with the lid and extended
downwards by a guide element which carries the discs and
cooperates with a guide element secured to the bottom of the container.

The device may include electrical means
to heat the discs; it is thus possible to accelerate the
diffusion of the liquid.

We have described below, by way of nonimitative example,
two embodiments of the device according to the invention, with
reference to the attached schematic drawing in which
FIG. 1 is a view in vertical section of a first embodiment, in the non-use position,
FIG. 2 is a view similar to FIG. 1, the device being in the position of use,
Figure 3 is a view similar to Figure 2 of a second embodiment.

 As shown in the drawing, the diffusion device according to the invention comprises a container or reservoir 1 which is here placed inside a decorative covering 2. A circular cage 3 which is formed of vertical uprights of height lower than that of container 1, is mounted sliding with gentle friction in container 1. The bars of the cage are interconnected at their lower part by a bottom 4 and, at their upper part, by a support disc 5 whose diameter is greater than that of container 1 and under which is fixed an axial tube 6 which can slide on a guide rod 7 fixed to the bottom of container 1. The bottom 4 of the cage 3 carries a sleeve 8 enclosing the lower part of the tube 6 .

 On the tube 6 are fixed a number of evaporator discs 9 made of felt or similar porous material, as well as a scraper disc 10. All of the discs which is housed in the cage 3 and the bottom 4 thereof are traversed by a vertical wick 11.

 A cover 12 covers the support disk and is fixed thereto; this cover can be applied to the covering 2, thereby closing the container 1, when the support disc 5 is in the low position.

 To use the device which has just been described, the assembly formed by the cage 3, the support disc 5, the tube 6 and the discs 9 and 10 is removed from the container 1, and a liquid to be diffused 13 is placed, for example a perfume, in container 1; then we put it back together. When the support disc 5 is in the low position (Figure 1) the wick 11 is soaked with the product 12 which comes by capillary action to impregnate the discs 9. The cover 12 closes the container 1 and prevents any diffusion.

 When the support disc is brought to the high position (Figure 2), the liquid product which permeates the discs 9 evaporates and diffuses into the atmosphere through the openings of the cage existing between the bars.

 By vertically moving the support disc 5, the surface of the cage 3 which has been uncovered is modified, and consequently the intensity of the diffusion of the active product in the atmosphere, which is thus adjustable.

 When the support disc is then returned to its low position, the cover 12 is applied to the covering 2 so that no evaporation takes place and the device can be kept unused without loss of product.

 In the embodiment of FIG. 3, an electrical resistance 14 connected to supply wires 15 is arranged around the tube 6. This resistance, the supply of which can optionally be timed or controlled by means sensitive to the quality of the ambient air, accelerates the evaporation of the active product impregnating the discs 9.

 I1 goes without saying that the present invention should not be considered as limited to the embodiments described and shown, but on the contrary covers all variants.
