  • Patent number: 6843969
    Abstract: An air cleaning device includes a bulb-shaped casing provided at one end with an attached portion to be attached an attaching portion and connected to a commercial power source and at the other end with an outlet, an ozone generator accommodated in the casing and an air supply portion formed in the casing for supplying air into the ozone generator. The ozone generator includes a needle first electrode having a distal end directed to the outlet and a cylindrical second electrode concentric with the first and second electrodes. Application of high voltage between the first and second electrodes induces electrical discharge therebetween, generates negative ions and ozone and releases a stream of air containing the generated negative ions and ozone from the first electrode to the second electrode and outlet.

  • Publication number: 20040076560
    Abstract: The present invention provides an ozonizer in which a discharge region may be increased without damaging ozone generating performance. In the ozonizer, electrode module(s) 102 an alternating current is applied between a first electrode 7 and a second electrode 3, and a discharge is brought about in a gap of the discharge region which is injected with a gas containing at least oxygen gas. In the first electrode 7, an ozone gas passage (8) for taking out ozone gas generated by the discharge region is formed between an electrode surface facing the discharge region and a side portion. A plurality of the ozone gas passages are dispersed in the first electrode. The plurality of ozone gas passages (8) collect and draw out ozone gas generated at a plurality of the discharge region locations inside the first electrode.

  • Patent number: 6713027
    Abstract: An apparatus and method for the use of ozone as a sterilant for many classes of surgical instruments which are at least partially metallic. Three features are the connection of a voltage carrying part of the instrument to be sterilized as the electrode of an ozone generating cell, which employs a glow discharge and maintaining the temperature of this electrode below 500° C., and that no solid dielectric exists between opposed electrodes in the ozone generating cell. Ozone is thereby localized about voltage carrying and any non-voltage carrying parts of the electrode connected instrument. The control of electrode heating helps to maintain the increasing atmospheric concentration of the ozone, which will however eventually reach a natural limit. Local heating of the electrode configuration is controlled where the instrument to be sterilized is connected at least periodically as the negative electrode.

  • Patent number: 6635153
    Abstract: An apparatus for purifying air comprising two electrodes having a dielectric material such as glass extending therebetween. The dielectric material is air permeable, for example, in the form of a bed of discrete particles such as glass beads. The electrodes are also air permeable, allowing the air to flow through the electrodes and dielectric. Ozone is generated by discharge at points of contact of the dielectric particles. Airflow through the device is improved, allowing greater cooling, and higher volumes of airflow but at lower concentrations of ozone production than with prior art devices, thus reducing toxicity.

  • Publication number: 20030086813
    Abstract: In a treatment method of room air by air ionization, sensors such as air-quality sensors, an airflow sensor, an air humidity sensor, an ozone sensor, are provided. Parameters such as oxidizable air components, relative humidity, flow velocity, flow volume, ozone level, and intensity of oxygen ions are measured. The level of ionization power of the ionization apparatus is determined by an electronic control device based on the measured parameters. The ionization power is lowered, when a predetermined ozone value is detected, and, when the ozone level continues to increase after lowering the ionization power indicating an external ozone source, ozone decomposition is initiated by changing a time period of the applied periodic alternating voltage, supplied in the form of alternating pulses or packages of alternating pulses of a preset number or a combination of alternating pulses and packages of alternating pulses of a preset number.

  • Patent number: 6521859
    Abstract: A system and method for preserving stored foods. The system and method utilizes an apparatus for generating ozone and other atoms and molecules resulting from the bombardment of a feed gas with electrons having, preferably, a first electrode positioned within a channel in a second electrode. The first electrode is a substantially sealed tube made of dielectric material, having at least one electron gun positioned proximate an end for firing electrons into the first electrode. In electrical communication with the electron gun is a rod, maintained in a tube also made of dielectric material, which acts to maintain a constant energy level through the length of the rod and thus the length of the electrode. Within the first electrode is an inert gas which, upon the firing of the electron gun, is formed into a plasma.

  • Patent number: 6426053
    Abstract: An ozone generator utilizing an ultraviolet light tube for generating ozone is disclosed. In this ozone generator, efficiency in converting oxygen to ozone is increased by imposing an electrical field around the light tube. This electrical field causes a theta pinch in the plasma of the light tube, increasing luminescence in the ultraviolet spectral range and exciting diatomic oxygen molecules passing through the electrical field. Thus excited, the diatomic oxygen is easier to disassociate and become converted to ozone.
