Abstract
A nebulizer includes a receptacle for containing a liquid, a liquid-drawing tube, and a hollow cover including a partition plate dividing an interior of the cover into first and second chambers, first and second conduits each having an inlet end adapted to be connected to a compressed gas supply tube, and an outlet end communicated with the first chamber, and a mist output tube communicating fluidly with the second chamber. A nebulizing unit is connected to the outlet end of the first conduit and the liquid-drawing tube for directing a first compressed gas from the first conduit to the liquid exiting from the tube to convert the liquid into a mist. The second conduit introduces into the first chamber a second compressed gas which entrains the mist when flowing to the second chamber and exiting through the mist output tube.
