WEARABLE CHEMICAL DISPENSER

摘要

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 a first timer to account for a passive release rate of the active and a second timer to account for an active release rate of the active. The first time and second timer are in communication with a useful life indicator to provide a signal to a user of the device to indicate when the substrate in the device for containing the active should be replaced.

主权项

1. A wearable device for dispensing an air treatment chemical, the device comprising:
a circular housing comprising an inlet for permitting air to enter into an interior space of the housing, and a plurality of outlets spaced substantially 360 degrees around the housing, the outlets permitting air mixed with air treatment chemical to exit the interior space; a substrate dimensioned to be positioned in the housing via a slot in the housing, the substrate bearing an air treatment chemical; a centrifugal fan mounted within the housing, the fan being capable of moving air from the inlet adjacent the substrate so as to mix air treatment chemical into the moving air, and then deliver a mixture of air and air treatment chemical through the outlets to outside of the housing.
