A water purifier and surface sanitizer uses an ozone generator but requires no air dryer, is adapted for simple maintenance and for use in remote areas from low-voltage DC. The sanitizer has a housing with a high-voltage supply device such as a pulse coil, coupled directly to a tubular inner electrode. A dielectric tube of borosilicate glass (e.g. PYREX) is shaped like a test tube with one open end, and slides over the inner electrode with a push fit. The dielectric tube is easy to clean since it can be pulled off the inner electrode, cleaned with acid/neutralizer or detergent to remove built-up surface contaminants, and replaced; this avoids any need for an air dryer. An outer electrode includes an air space (corona space) and gaps for ventilation. Air passes over the dielectric, becoming ozonated by the high voltage, and is drawn into a water stream by a venturi. The water may also pass through a particle filter. The water flow is controlled by a fully-on or fully-off faucet. |
