Description
Technical Field
The invention relates to the technical field of negative ion generators, in particular to a capacitance-based negative ion generating circuit.
Background
The negative ion generator is a device for generating air negative ions, and the device processes the input direct current or alternating current through an EMI processing circuit and a lightning stroke protection circuit, and then performs overvoltage current limiting through a pulse circuit; the high-low voltage isolation and other circuits are raised to AC high voltage, then pure DC negative high voltage is obtained after rectifying and filtering by special grade electronic materials, the DC negative high voltage is connected to a release tip made of metal or carbon element, high corona is generated by using the tip DC high voltage, a large amount of electrons (e-) are released at high speed, the electrons cannot exist in the air for a long time (the service life of the existing electrons is only nS level), and the electrons are immediately separated by oxygen molecules (O) 2 ) Capturing, thereby generating air anions. The negative ions purify the air, can improve the water environment and are beneficial to the health of human bodies. Negative ions, current and static electricity are related to electrons, but the movement modes are different, each has respective purposes, the negative ions are significant for human health, technical workers in the related field are required to find better negative ion generation modes to realize high-concentration negative oxygen ions without ozone and superoxide, and attempt to generate negative ions by adopting a low-voltage technology, the concentration of the negative ions is very limited, and experts in the related field are required to obtain high-concentration negative ions by continuously increasing the level of voltage, because the higher the voltage is, the easier the air is broken down, and most of electrons run to the positive electrode, and the monopole is easy to run to the ground just like a current short circuit. There are also experiments to simulate the mutual interaction of water in natureThe friction principle is used for generating negative ions, which is the result of electron escape caused by mutual friction and collision of the outer layer orbit electrons of water molecules based on the principle of like charges, some of the negative ions are generated by using new materials, some of the negative ions are generated by using mineral thermoelectric effect, the concentration of the negative ions is not ideal, and is difficult to be compared with that of the negative ions in forests and seasides, so that the maximum negative oxygen ion concentration of the theoretical air cannot be solved, the negative ions generated by using a power supply are the only way of obtaining high-concentration negative ions, and the like charges and the opposite charges are in accordance with the principle of the most basic physical principle of the like charges and the opposite charges of coulomb law, the acting force is in direct proportion to the two electric charge amounts and in inverse proportion to the distance between the two charges. The existing bipolar high-voltage negative ion generator is easy to cause electrons to run to the positive electrode, and ionized air can generate ozone; a monopolar negative high-voltage negative ion generator is developed, the concentration of negative ions generated by the method is much higher than that of negative ions generated by bipolar high voltage, the air is ionized under the condition that the voltage is too high, ozone is generated, the electrode is limited by the small surface area of the electrode needle point and the electrostatic skin effect, a large amount of electrons are difficult to gather on the needle point, and the concentration of the negative ions obtained by increasing the voltage level is difficult to break through 2 multiplied by 10 9 /cm 3 This is far from the theoretical concentration limit. As such, there are related studies that use the principle of capacitance to collect a large amount of electrons on the negative electrode layer and try to separate the electrons from the conduction band of the negative electrode layer, as in chinese patent: patent name: a low-voltage negative oxygen ion generator, patent number: 201420679363.8 the principle and method of combining more electron release with oxygen in air by adopting a capacitance mode have the advantages that the principle and method have great advantages compared with the method of releasing negative ions by a needle point, but the distance between the positive electrode layer and the negative electrode layer is far, the corresponding voltage requirement is high, and if the distance between the positive electrode layer and the negative electrode layer is shortened, the air passing amount is greatly limited.
It is therefore a further improvement to develop a circuit which has a short charge interaction distance and which is capable of continuously generating negative ions.
