Abstract: A hand held personal care appliance, such as a hair dryer, has a liquid delivery system for delivering a spray of liquid from the appliance. The liquid delivery system has a reservoir for containing a supply of liquid and a liquid transfer system. A rotatable drum has a surface in fluid communication with the liquid transfer system for receiving liquid onto the surface of the drum. A drive system rotates the drum such that the liquid is thrown from the drum by centrifugal force of the rotating drum for delivering liquid from the appliance in the form of a spray of droplets. In some embodiments, the fluid transfer system includes a first wick for delivery of the liquid to the drum and a second wick for delivery of liquid to the first wick. The reservoir and other parts of the liquid delivery system may be a disposable cartridge.
