Изобретение относитс к области медицины, а именно к устройствам дл искусственной ионизации воздуха, и предназначено дл получени аэроионов .The invention relates to the field of medicine, namely to devices for artificial ionization of air, and is intended to produce air ions.

Известно устройство дл ионизации воздуха состо щее из источника питани и коронирующих электродов 1.A device for air ionization is known, which consists of a power source and corona electrodes 1.

Недостатком этого устройства вл етс отсутствие контрол работот способности в процессе работы, что снижает эффективность, надежность, безопасность и удобство его в работе.A disadvantage of this device is the lack of performance monitoring of the ability during operation, which reduces its efficiency, reliability, safety and convenience in operation.

Наиболее близким к изобретению решением по технической сущности вл етс устройство, содержащее истойник питани , коронирующий электрод и узел самоконтрол , включающий по следовательно Ьоединенные индикатор и резистор Г 21.The closest to the invention to the solution of the technical essence is a device containing a power source, a corona electrode and a self-monitoring node, including in turn a connected indicator and a resistor G 21.

Возможные утечки электрических зар дов в узле самоконтрол , размеще- . ние металлического электрода непосредственно в поле коронирующего электрода и накопление на нем значительного количества аэроионов, генерируемых аэроионизатором, снижают помехозащищенность устройства, эф фективность и безопасность его экс- плуатации.Possible leakage of electrical charges in the self-monitoring node, location-. The metal electrode directly in the field of the corona electrode and the accumulation on it of a significant number of air ions generated by the aeroionizer, reduce the noise immunity of the device, the efficiency and safety of its operation.

Целью изобретени вл етс повышение помехозащищенности.The aim of the invention is to improve the noise immunity.

Поставленна цель достигаетс тем, что в устройстве дл ионизации воздуха , содержащем источник питани , коронирующий электрод и узел самоконтрол , включающий последовательно соединенные индикатор и резистор, в узел самоконтрол введены соединенные между собой дополнительный резистор и полупроводниковый резистор, при этом The goal is achieved by the fact that in a device for ionizing air, containing a power source, a corona electrode and a self-monitoring unit, including a series-connected indicator and a resistor, an interconnected additional resistor and a semiconductor resistor are inserted into the self-monitoring node, while

Claims

Twenty-one terminals of each of the last resistors are connected to a power source, and their midpoint is with an indicator. On the dead (e is the circuit diagram of the device for air ionization, the device for air ionization contains a power source 1, a corona electrode 2 and a self-control node, which consists of an additional resistor 3 of semiconductor resistor 4, resistor 5 and indicator b The device operates as follows, at once. The power source 1 produces a high negative polarity voltage necessary to obtain corona power. The corona discharge from the tip of the corona electrode 2 ionizes the air. From the resulting pairs of ions, the positive ions are neutralized to the tip of the corona electrode 2, and the negative ones form a stream of aero ions. the semiconductor resistor C located at the corona electrode 2 in the stream of air ions, and the nominal capacity of the device for air ionization, the resistance of the semiconductor resistor b decreases. This changes the voltage drop across resistor 3 to the amount needed to light the indicator 6 connected in series with resistor 5 and intended to visually indicate the presence of a stream with a certain concentration of negative aeroions. During operation, the influence of leakage currents and the effect of accumulation of electric charges in the self-control node circuit on the accuracy and reliability of monitoring the operating modes of the entire device is eliminated, which is ensured by high noise immunity. Claims An air ionization device comprising a power source, a corona electrode and a self-monitoring unit including an indicator connected in series and a resistor, characterized in that, in order to increase the noise immunity, an additional resistor and a semiconductor resistor are interconnected, while One pin of each of the last resistors is connected to the power supply, and their midpoint is with an indicator.
