摘要： A surface deodorizer which can be used as a vacuum cleaner is disclosed. The surface deodorizer is comprised of a housing equipped with a motor and blower, a filter bag and a filter element. A flexible hose and conduit is used to connect the housing to a suction head, which has a build-in ozone/oxidant generator, makeup air grills and a suction inlet. Ozone/oxidant generated by the generator come in contact with an odorous surface through the action of airflow suction created by the motor and blower, thereby removing the stinky odor and dust particles from the surface. The excess ozone/oxidant and exhaust air are filtered through a filter bag and filter element positioned between the suction head and the motor and blower.

摘要： Sequencing air cleaning rejuvenation system relates to a method and apparatus for air cleaning. More specifically, air contaminants and bacteria are removed from polluted environment by adsorption until the adsorption filter (2) is nearly saturated. By employing such method and apparatus, the adsorption materials (8) are then refreshed in a rejuvenation chamber (3) by reacting with reactive oxidizing species. The rejuvenation process decomposes air contaminants into non-harmful products without causing secondary pollution. Since the adsorption and rejuvenation process are taken place separately, it causes no noise disturbance and no leakage of excess ROS. Comparing with conventional air purifier, the sequencing air cleaning rejuvenation system is relatively more versatile and can be applied in various situations, especially in case of no power supply.
