Abstract: A device for vaporizing a fluid desired to be introduced into the air by forcibly moving air over the surfaces of an absorptive material which has been impregnated with the fluid desired to be distributed. The device comprises a housing adapted to be attached to a wall or other surface and utilizes a liquid material contained within a hollow container which is so positioned within the housing that the liquid flows into a cup-like member within which a layer of the absorptive material is disposed. The cup-like member includes at least one opening over which air is caused to pass and thereby evaporate the liquid from the absorptive material. A battery powered fan is so positioned as to cause the air to flow past the opening in the cup member and thereby evaporate some of the vaporizable fluid. The entire assembly is contained within a housing which has an air inlet and an air plus vapor outlet, and includes means for properly positioning the several elements in the proper relationship.
