Title: Chemical diffusion device having a material for absorbing liquid chemical and transferring the chemical to a gas flow

Abstract: A permeable saturation body absorbs a liquid chemical for evaporative dispersion. External air is forced through the saturation body to vaporize and carrying the liquid chemical into a prescribed area. The liquid container and permeable body are mounted on a permeable support structure. Excess liquid dripping from the permeable saturation body is recaptured and redistributed by another permeable saturation body located below the first permeable saturation body. The device can be used in greenhouses to disperse insecticide into the air or along the ground. The device is also adapted to disperse deodorant or a bactericide for use in hospitals or restaurants, for example. One embodiment of the invention provides for reversible air flow so that a user can choose between dispensing the liquid chemical in a low position, or in a high position.
