Wearable chemical dispenser

WEARABLE CHEMICAL DISPENSER Wearable devices (18) for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human are disclosed. They are of the type that are clipped onto a belt or the like, and use a powered fan (60) to dispense active. They are configured with fan rotor (61) arrangements to minimize power use while still achieving acceptable air flow rates. These changes permit use of smaller batteries and more compact arrangements for battery positioning. This in turn permits a much more compact and lightweight construction to achieve the desired results. The devices (18) are also provided with a rotatable clip structure (110) to render use of the device more comfortable when the user is seated and to provide greater control over the direction of the dispensing. Further, they are provided with modified lids to facilitate active refill replacement.
