Abstract:
1. An atomizer for atomizing liquids, comprising: a liquid storage receptacle in the form of a dimensionally flexible liquid-containing bladder, an atomizing device having an atomizing chamber that communicates with the ambient atmosphere via a plurality of outlet orifices, the atomizing device having a liquid inlet and a liquid outlet each communicating with the atomizing chamber, and further having a vibrator which vibrates liquid present in the atomizing chamber to atomize same, the atomizing chamber being delimited on one side by the outlet orifices and on an opposite side by a vibrating wall which is vibrated by the vibrator, an intake channel fluidly interconnecting said liquid storage receptacle to the liquid inlet of the atomizing device, a debubbling device located in the intake channel, said debubbling device having a channel portion through which liquid flows on its way to said atomizing chamber and which channel portion is partly delimited by a filter surface, wherein said channel portion: an electrically actuated pumping device provided in said intake channel for delivering liquid from said liquid storage receptacle to said atomizing chamber, an electronic control device electrically controlling said pumping device and said vibrator, said atomizing device and said pumping device being configured or being controlled by said control device such that during atomization a pumped volumetric flow rate of the liquid transported by said pumping device is greater than a discharged volumetric flow rate through said outlet orifices as achieved by said atomizing device, and a return channel distinct from said intake channel, the return channel fluidly interconnecting the liquid storage receptacle to the liquid outlet of the atomizing device, the return channel draining liquid from said atomizing chamber into said liquid storage receptacle.
