Abstract: A nebulizer composed of shell with air inlet and lid with spray nozzle. Inside the shell, lays, from bottom to top, a drug cup with piezoelectric transducer and spray chamber with spray outlet. Nebulizer includes vertical air vent lying from bottom air inlet, through middle spray nozzle, to top spray outlet. Moreover, an electric fan lies inside air inlet. Components of piezoelectric ceramic transducer are as follows (mass percentage): lead tetraoxide (Pb3O4, 63.3˜68.3%), zirconium dioxide(ZrO2, 14.2˜15.3%), titanium dioxide (TiO2, 8.1˜9.5%), strontium oxide (SrO, 4.6˜5.2%), iron sesquioxide (Fe2O3, 1.5˜1.8%), stannic oxide (SnO2, 1.0˜1.4%), manganese dioxide (MnO2, 0.3˜1.1%), cerium sesquioxide (Ce2O3, 0.5˜0.8%), columbium pentoxide (Nb2O5, 0.4˜0.8%), zinc oxide (ZnO, 0.3˜0.7%). Nebulizer is small in size, with low power consumption and lower cost, and is able to produce mist with small particle size.
