Abstract: A constructive arrangement introduced into fan having volatilizing function of repellent substance in a strip. The arrangement has a strip containing a substance to be dispersed into the environment is disposed at the front part of the supporting column of the fan, beneath the perimeter of its propellers, creating a pressure difference which provides for the propagation of the dispersion of the substance into the environment, and where the supporting column of the fan, besides acting as a barrier against air flows produced in the environment, preventing the dilution of the volatilized mist, will also enable the enclosure of the electrical wires used in the connections, making energizing the volatilizing combination much easier, more practical and economical.

Abstract: Embodiments described herein relate to a base chamber closed by a cover having a support that receives a liquid-repellent refill of any commercially available model, which separates the chamber at the bottom for accommodating the reservoir from the upper part for the wick which, duly heated by a PTC heating device, has the stream of air directed to the release windows where negative pressure conveys the repellent towards the blades of the fan. In further exemplary embodiments, the device aims to optimize steam releasing from the repellent contained in the refill into the chamber to the environment by way of a hose connected to a tube projecting from said chamber to an oblique support located at the front of the top finish of the column of the fan, where the negative pressure is more pronounced.
