Abstract (en)
[origin: WO2017046500A1] Liquid atomizer (6) comprising a piezoelectric element (8) fixed on a vibrational-displacement amplifying horn (9) comprising a cavity (90) containing the liquid that is to be atomized, the said horn (9) comprising a first part (92) receiving the piezoelectric element (8) and a second part (93), distinct from the first part (92), coupled mechanically and acoustically to a microperforated membrane (91) that closes off one side of the said cavity (90), characterized in that the said cavity (90) is supplied with liquid coming from a reservoir (5) by means of a pump (51) having a throughput greater than the spray throughput of the atomizer (6) in operation, and in that the said horn (9) comprises at least one outlet hole (94) connecting the cavity (90) to a bypass pipe (66) leading towards the reservoir (5).
