Aerosol dispensing apparatus
A dispensing system adapted for repeated activation of an aerosol can is described. The dispensing system includes components that improve the ability to receive and secure aerosol cans of different sizes within the dispensing system as well as improving the reliability and energy efficiency of the system.
1. An aerosol can dispenser for determining if an aerosol can is authorized for use with the aerosol can dispenser wherein the aerosol can dispenser comprises:
a. a controller having means for activation of the aerosol can dispenser for repeated activation of the aerosol can nozzle by an aerosol can dispensing mechanism;
b. a mount for mounting an aerosol can to the aerosol can dispenser to engage the aerosol can nozzle with the aerosol can dispensing mechanism;
c. at least one LED emitter/receiver pair operatively connected to the controller, the LED emitter/receiver pair configured to emit LED light against an outer surface of an aerosol can and to receive reflected light from the outer surface of the aerosol can;
wherein the controller is configured such that, if the reflected light signal pattern is authorized, the aerosol can dispensing mechanism is enabled to dispense a quantity of aerosol can contents and, if the reflected light signal pattern is not authorized, activation of the aerosol can dispensing mechanism is prevented.
2. The aerosol can dispenser according to claim 1 , wherein the emitter and receiver of the emitter/receiver pair are positioned at different levels within the dispenser so as to operatively connect with a single photoreflective band at a specific height.
3. The aerosol can dispenser according to claim 1 , wherein the aerosol can dispenser comprises multiple emitter/receiver pairs.
4. The aerosol can dispenser according to claim 1 , wherein the controller is configured to implement a predetermined dispensing cycle.
5. The aerosol can dispenser according to claim 1 , wherein the aerosol can dispenser comprises multiple emitter/receiver pairs arranged at different heights.
6. The aerosol can dispenser according to claim 1 , wherein the emitter/receiver pair is positionable at different levels relative to the dispenser.
7. The aerosol can dispenser according to claim 1 , wherein the aerosol can dispenser is battery powered.
8. The aerosol can dispenser according to claim 1 , wherein the aerosol can dispenser forms part of an air freshener system.
9. The aerosol can dispenser according to claim 1 , wherein the aerosol can dispenser is configured to initiate a dispense cycle based on a time signal.
10. The aerosol can dispenser according to claim 1 , wherein the aerosol can dispenser is configured to dispense according to a dispensing schedule.
11. The aerosol can dispenser according to claim 1 , wherein the aerosol can dispenser is configured adjust dispensing frequency based on the time of day.
