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: is formed by a groove in a base component of the atomizer, the groove being closed by said filter surface, the filter surface being flat and porous and positioned on said base component, orhas at least two straight portions interconnected by at least one curved 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, anda 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. 2. The atomizer as defined in claim 1, wherein the pumped volumetric flow rate during atomization is greater than the discharged volumetric flow rate by at least 20%. 3. The atomizer as defined in claim 1, wherein said control device is adapted to first activate only said pumping device in a preparatory phase prior to commencement of a discharging operation, and second to additionally activate said vibrator on termination of the preparatory phase. 4. The atomizer as defined in claim 3, wherein said pumping device is configured or is controlled by said control device in such a manner, and said outlet orifices of said atomizing device are constructed in such a manner, that the pressure achieved in the atomizing chamber in the preparatory phase is not sufficient to force liquid through said outlet orifices. 5. The. atomizer as defined in claim 1, wherein the debubbling device is provided between said pumping device and said atomizing chamber. 6. The atomizer as defined in claim 1, wherein said pumping device is configured or is controlled by said control device in such a manner, and said debubbling device is configured in such a manner, that the pressure established in said debubbling device suffices to force gas through the filter surface but is not sufficient to force liquid through said filter surface. 7. The atomizer as defined in claim 1, wherein the liquid present in said liquid storage receptacle contains a pharmaceutically active substance or is a cosmetic product. 8. An atomizer for atomizing pharmaceutical or cosmetic liquids, said atomizer comprising: a liquid storage receptacle;an atomizing device defining an atomizing chamber, a plurality of outlet orifices in fluid communication with said atomizing chamber and the atmosphere, a liquid inlet and a liquid outlet each in fluid communication with said atomizing chamber, and a vibrating device disposed closely adjacent said atomizing chamber which when actuated vibrates liquid located within said atomizing chamber in order to atomize same;an intake channel disposed to provide fluid communication between said liquid storage receptacle and said liquid inlet of said atomizing device to place said atomizing chamber in fluid communication with said liquid storage receptacle and allow delivery of fluid therein to said atomizing chamber;an electrically-actuated pumping device disposed to deliver liquid from said liquid storage receptacle to said atomizing chamber via said intake channel;an electronic control device electrically controlling and electrically connected to said pumping device and said vibrating device; a return channel separate and distinct from said intake channel, said return channel fluidly interconnecting said liquid storage receptacle to said liquid outlet of said atomizing device to drain liquid from said atomizing chamber and recirculate liquid therein back into said liquid storage receptacle;a housing in which said liquid storage receptacle, said atomizing device, said intake channel, said pumping device, said control device and said return channel are disposed; anda debubbling device disposed between said pumping device and said atomizing chamber in said housing, said debubbling device including a base component and a porous membrane disposed in opposed relation with one another within said housing, said base component defining therein a debubbling groove closed on a side thereof by said membrane, said debubbling groove being in fluid communication with and forming part of said intake channel and having two substantially straight portions and a curved portion disposed between said two substantially straight portions. 9. The atomizer of claim 8, wherein said atomizing chamber is disposed between said liquid inlet and said liquid outlet. 10. The atomizer of claim 8, wherein said atomizing device includes a perforated plate defining therein said outlet orifices and a vibrating wall disposed in juxtaposed and facing relation with said perforated plate, said vibrating device being attached to said vibrating wall and vibrating same when actuated by said control device. 11. The atomizer of claim 8, wherein said control device electrically actuates only said pumping device in a preparatory phase prior to commencement of a discharging operation of said atomizer, said atomizer in the preparatory phase being configured to deliver liquid from said liquid storage receptacle to said atomizing chamber via said intake channel and then to recirculate the liquid to said liquid storage receptacle via said return channel, said pumping device achieving a pressure in said atomizing chamber in the preparatory phase which is insufficient to force liquid through said outlet orifices. 12. The atomizer of claim 11, wherein said control device electrically actuates both said pumping device and said vibrating device upon termination of the preparatory phase to commence the discharging operation, said atomizer during the discharging operation dispensing liquid through said outlet orifices, wherein a pumped volumetric flow rate of liquid transported by said pumping device during the discharging operation is greater than a discharged volumetric flow rate of liquid dispensed through said outlet orifices.
