Abstract
An illustrative control system for use with a replaceable ozone generator cartridge for use with an aqueous ozone delivery device, for example, for sanitizing objects, including hands, hands and forearms, feet, other tissue, instruments, or other object sanitizing. One embodiment of the control system calculates and transmits usage data to a memory device of the ozone generator cartridge, and also includes various sensors and drivers for controlling an aqueous ozone concentration. The control system also provides other data logging, error detection, and identity verification of the replaceable ozone generator cartridge.
Claims18
A system for controlling a replaceable ozone generator cartridge used with an aqueous ozone delivery device, the system comprising:
- a power supply;
- a controller for operating the replaceable ozone generator cartridge;
- a memory device for storing usage data;
- and
- a first ozone generator power driver operatively coupled to the controller and to the power supply to provide a variable power to a first electrolytic aqueous ozone generator located within the replaceable ozone generator cartridge, the variable power level selected based at least in part on a selected ozone concentration level to be produced by the replaceable ozone generator cartridge;
- and
- at least one aqueous ozone quality sensor located within the replaceable ozone generator cartridge and providing a first sensor data signal to the controller corresponding to a measured parameter of operation of the replaceable ozone generator cartridge relevant to the ozone concentration level produced by the replaceable ozone generator cartridge;
- and
- wherein:
- the aqueous ozone delivery device includes at least the controller;
- the replaceable ozone generator cartridge includes at least the memory device;
- the controller is configured to receive usage data for the replaceable ozone generator cartridge from the memory device and to calculate and transmit updated usage data to the memory device;
- the controller is configured to control the first ozone generator power driver based at least in part upon the signal received from the at least one aqueous ozone quality sensor;
- the at least one aqueous ozone quality sensor includes a first oxidation-reduction potential sensor located within the replaceable ozone generator cartridge and downstream of the first electrolytic aqueous ozone generator, the first oxidation-reduction potential sensor providing the first sensor data signal, a measurement of the oxidation-reduction potential of water downstream of the first electrolytic aqueous ozone generator;
- and
- the controller determines a power level of the first ozone generator power driver based at least in part on the first sensor data signal;
- and
- wherein the controller is configured to receive the first sensor data signal during:
- a first state in which water flow is provided through the replaceable ozone generator cartridge without the first ozone generator power driver providing power to the first electrolytic aqueous ozone generator;
- and
- a second state in which water flow is provided through the replaceable ozone generator cartridge with the first ozone generator power driver providing power to the first electrolytic aqueous ozone generator;
- and
- wherein the controller is configured to control the first ozone generator power driver based at least in part on the difference between the first sensor data signal received during the first state and the first sensor data signal received during the second state to provide a selected aqueous ozone concentration during the second state.
