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.

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. 2. The device of claim 1 wherein: the inlet comprises a first section including a plurality of spaced apart apertures and a cover section including a plurality of spaced apart vent openings, andthe cover section is movable from a first position in which the cover section covers the plurality of spaced apart apertures of the first section to a second position in which the plurality of spaced apart vent openings of the cover section are at least partially aligned with the plurality of spaced apart apertures of the first section. 3. The device of claim 2 further comprising: a power supply mounted within the housing; anda motor mounted within the housing, the motor being powered by the power supply and the fan being connected to the motorwherein the power supply includes a battery, andthe motor has a current draw such that power of the device is 50 milliwatts or greater when the battery is fully charged. 4. The device of claim 2 wherein: the vent openings of the cover section include at least a first size of openings of a first inside diameter and a second size of openings of a second inside diameter smaller than the first inside diameter, andat least a first group of the first size of openings is arranged further away from a center of the cover section than a second group of the second size of openings. 5. The device of claim 2 wherein: the vent openings of the cover section include a plurality of sizes of openings, anda size of openings having the largest inside diameter is arranged about half way between a center of the cover section and an outer periphery of the cover section. 6. The device of claim 1 further comprising: a clip rotatably connected to an outer wall of the housing, the clip being structured to rotate 360 degrees with respect to the housing. 7. The device of claim 6, wherein: the clip includes a slot. 8. A refill adapted for use in a wearable device for dispensing an air treatment chemical wherein the device includes a housing comprising an inlet for permitting air to enter into an interior space of the housing, and an outlet permitting air mixed with air treatment chemical to exit the interior space, the refill comprising: a substrate dimensioned to be positioned in the housing via a slot in the housing, the substrate having a first end, a second end opposite the first end, a first side, and a second side opposite the first side, the substrate bearing an air treatment chemical,wherein the second side of the substrate includes an alignment profile that cooperates with an alignment structure in the slot such that the first end of the substrate faces away from an opening of the slot and the second side of the substrate faces the inlet when the substrate is positioned for use in the housing, and the alignment profile is partially defined by a tab that extends away from the second side of the substrate adjacent the second end of the substrate. 9. The refill of claim 8 wherein: the substrate includes an outer wall, andthe alignment profile is partially defined by a notch in a section of the outer wall adjacent the first end of the substrate. 10. The refill of claim 9 wherein: the alignment structure in the slot comprises a stop rib extending away from the inlet. 11. The refill of claim 10 wherein: the notch travels past the stop rib when the substrate is inserted in the opening of the slot with the first end of the substrate facing into the interior space of the housing and the second side of the substrate facing the inlet. 12. A wearable device for dispensing an air treatment chemical, the device comprising: a housing comprising an inlet for permitting air to enter into an interior space of the housing, and an outlet for permitting air mixed with air treatment chemical to exit the interior space;a substrate positioned within the housing, the substrate bearing an air treatment chemical;a power supply mounted within the housing;a motor mounted within the housing, the motor being powered by the power supply;a fan mounted within the housing and connected to the motor, 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 outlet to outside of the housing; anda switch for activating and deactivating the motor,wherein a top section of the housing is rotatably coupled to a bottom section of the housing, the top section of the housing being rotated to contact the switch and activate the motor. 13. The device of claim 12 wherein: the top section of the housing has a first position for positioning the substrate within the housing, andthe top section of the housing has a second position for securing the substrate within the housing, andthe top section of the housing has a third position for contacting the switch. 14. The device of claim 12 further comprising: a controller in electrical communication with the switch and an indicator of useful life for the substrate, the controller executing a stored program to activate the indicator based on a signal from the switch. 15. The device of claim 14 wherein: the controller executes the stored program to: (i) adjust a value of a counting device when the switch is contacted, and(ii) activate the indicator when the value of the counting device equals a predetermined value. 16. The device of claim 12, further comprising: an actuator positioned within the housing, wherein the substrate actuates the actuator when the substrate is positioned within the housing; anda controller in electrical communication with the switch, the actuator, and an indicator of useful life for the substrate. 17. The device of claim 16 wherein: the controller executes a stored program to: (i) start adjusting a value of a counting device when the substrate actuates the actuator;(ii) adjust the value of the counting device when the motor is activated; and(iii) activate the indicator when the value of the counting device equals a predetermined value. 18. The device of claim 17 wherein: the counting device includes a first timer and a second timer, andactuation of the actuator initiates the first timer, andactivation of the motor initiates the second timer. 19. The device of claim 18 wherein: the value of the counting device is adjusted based on first timing signals from the first timer and second timing signals from the second timer.
