Wearable devices 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 to dispense active. They are configured with fan rotor 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 are also provided with a rotatable clip structure 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.

Wearable chemical dispenser

A solenoid valve assembly is adapted to control product flow through a dispensing system. The dispensing system includes a housing. A plunger is disposed within the housing and has a first axial surface. A stopper is also disposed within the housing and has a second axial surface facing the first axial surface. At least one flow pathway is provided on at least one of the first and second axial surfaces.

Solenoid valve assembly for a dispensing system

Disclosed herein are wearable devices for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human, to avoid the need to apply such chemicals directly to clothing or to human's skin. The devices have an on/off switch that automatically controls a shutter which enables and restricts air flow, while also controlling fan operation and covering of a use-up cue. The device also is designed to prevent fan operation when an impregnated slab is not present. Also disclosed are preferred refills for use with such devices.
