1) Ventilation device for a micronizer with a body and an active part, utilizing a ventilation fluid, in particular air, wherein it comprises:
a base substantially on a plane; a first frame fixed to a side of said base and comprising a housing in which the body of said micronizer is partially insertable, in such a way that the active part of said micronizer extends above said housing in the direction perpendicular to said plane;and wherein:
said housing is shaped in such a way to form, in use, with said micronizer, an internal perimetrical chamber, in particular on a second plane parallel to said plane; said internal perimetrical chamber presents an entrance for said ventilation fluid; said internal perimetrical chamber presents, along its extension, a plurality of holes which present an outlet opening towards said base, said base comprises a main hole into which said micronizer is partially insertable, said main hole presenting a perimetrical region with a radial section including from the inside to the outside:
a first ridge connected by an inclined surface to a bottom that is lower than the first ridge;a second inclined surface connecting said bottom to a second ridge, in such a way to form an overall surface having a “U”-type section; said frame comprises a portion facing said first inclined surface and forming with it an interspace through which, in use, said ventilation fluid exiting said plurality of holes can flow. |
