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.

Abstract: A liquid storage container, in which an extermination liquid is stored, is at an upper portion of a case. A gauze or other permeable material is mounted on the outer surface of a support on a lower portion of the liquid storage container. An upper end of a portion of the gauze is transferably connected to the liquid storage container to transfer extermination liquid to the rest of the gauze by wicking action. Capillary action causes the extermination liquid to saturate the gauze. A sirocco fan and a motor, below the gauze, causes air from outside to be drawn into the case from an opening on the upper portion of case. The air passes through and around the gauze, causing vaporization of the extermination liquid in the gauze. The vaporized extermination liquid, cooled and densified by vaporization, is blown outside the case through a lower ventilation opening of the case.
