Abstract
A liquid pumping device, particularly useful as nebulizer, includes a receptacle for receiving a quantity of a liquid to be pumped, a hollow conical tube having a small-diameter end located to be immersed in the liquid to be pumped, and a larger-diameter end located above the liquid to be pumped, and a drive for rotating the hollow conical tube about its longitudinal axis to pump by centrifugal force liquid therethrough from its small-diameter end to its larger-diameter end. When the device is used as a nebulizer the hollow conical tube includes a plurality of holes at vertically spaced locations, and a plurality of annular discs secured to the outer surface of the conical tube each underlying one or more of the holes.
