Problems solved by technology

[0003] [03] These various diffusers require the implementation of relatively complex hitches
Alternatively, due to the fact that these devices are located in the middle of the air flow, these devices have problems falling out when the air flow is high, or have deficiencies in shaking or vibration that create unpleasant noises for passengers

Embodiment Construction

[0022] [22] An embodiment of the diffuser 1 according to the present invention will be described with reference to the drawings.

[0023] [23] The diffuser 1 has a closed annular lower edge 2, from which extends an open-enlarged side wall 3, which terminates in an annular upper edge 4 with a diameter greater than The diameter of the lower edge 2 . The side wall 3 extends over the entire circumference of the lower edge 2 .

[0024] [24] The diffuser thus assumes the general shape of a funnel with a central opening. Said inner surface is defined as the surface delimiting this opening compared to the outer surface.

[0025] [25] In said example, said diffuser has a rotational symmetry, the axis of said two annular edges coincides with the axis of rotation of said side wall 3 .

[0026] [26] The lower edge 2 has, over its entire circumference, a bead 5 which extends on the outer surface of the side wall substantially perpendicularly to the side wall 3 . In said example, said p...

Abstract

The invention relates to a dispenser for one or more volatile substances (1), which is intended for a motor vehicle ventilator of the type that has an opening which is located at the base of a recess. The inventive dispenser comprises a lower edge (2) having essentially the same shape and dimensions as the periphery of the opening in the ventilator and a lateral wall (3) which is made from a material that can be impregnated with one or more volatile substances and which flares out from the aforementioned edge (2). The edge (2) is also equipped with support means (5) for holding the dispenser on the periphery of the ventilator opening.

Description

technical field [0001] [01] The present invention relates to volatile substance diffusers for motor vehicles, and more particularly to a static type diffuser. Background technique [0002] [02] The static diffuser has a sheet or granular substance, or a material impregnated with a substance, whose effluve is slowly and irregularly emitted into the ambient space. In order to improve said distribution, certain diffusers are provided by means of a clip, for example as described in document US-6 264 887, by a velcro type of fixing as described in document US-4 813 344, or as described in document A compressible elastic block insertable between the ventilator blades described in US-5 762 549 hangs from said ventilator blades. Some diffusers are inserted completely into the ventilator as in document US-5 269 723, or have hook means inserted between the louver blades as in document GB-2 263 404. [0003] [03] These various diffusers require the implementation of relatively comple...
