to knobs c 1 c 2 and t in fig1 and 2 the nebulizer of fig3 further includes blower means comprising a blower 130 and a conduit 132 for directing a stream of air to flow through a path to pick up the liquid nebulized by the nozzle 118 this stream of air is first heated by a heater 134 applied around the conduit 132 the amount of heat applied to this stream of air can be controlled by a further control knob c c in the power supply unit 116 the nebulizer illustrated in fig3 operates in substantially the same manner as described above with respect to fig1 and 2 except that it heats the atomized liquid discharged from nozzle 118 and also isolates the two electrodes 112 114 from the liquid 106 fed to be nebulized thus liquid 126 immersing the electrodes may be water whereas liquid 106 to be nebulized may also be water or another liquid containing a medication or other ingredient which might be affected by the electrodes or by the electrical current passing through the electrodes the nebulizer illustrated in fig3 is thus particularly useful for therapeutic purposes in order to apply a stream of humidified hot air with or without medicaments e g to the nostrils of the user it will be appreciated that heater 134 could also be applied to the embodiment illustrated in fig1 and 2 or fig4 described below if it is desired to heat the nebulized liquid fig4 illustrates a further embodiment of the invention wherein the nebulizer.
