Technical Field
The utility model belongs to the technical field of anion emission technique and specifically relates to an anion emission device.
Background
In the prior art, the generation of negative ions mostly adopts the mode that high voltage is added on an ion needle, so that the negative ions are continuously released, and the negative ions are combined with the ambient oxygen to form negative oxygen ions. But in this process its current tends to break down the oxygen molecules in the air, thereby creating ozone and nitrogen oxides. In addition, the electron moving track must pass through a loop formed by space and ground, so a local high-voltage electric field is formed, and the high-voltage electric field can interfere peripheral electronic instruments and cause radiation to people to influence health.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical deficiencies and providing an anion emission device, can not produce electrostatic field on a large scale at the equipment periphery, reducible constraint to the anion.

Above-mentioned technical scheme, power connection terminal connects commercial power 220V, carries the negative high pressure to the negative ion emission needle through high voltage generator, so can produce a large amount of anions at the negative ion emission needle, and the matching needle is close to relatively with the negative ion emission needle, and the negative ion can follow the matching needle and get into earthing terminal or other end, as the optimal choice, power connection terminal's zero line end is connected to the impedance matcher, and the impedance between matching needle and the zero line end can be adjusted to the impedance matcher, when impedance increases, the ability decline of negative ion through the impedance matcher, so have a large amount of anions by the extrusion electric field, form free anion in the entering air, do not bind by the electric field. Therefore, through the process, the electrostatic field generated by the device is limited between the negative ion emitting needle and the matching needle, no electrostatic field is generated at the periphery, and meanwhile, the amount of the negative ions separated from the electrostatic field is adjusted through the impedance matcher, so that the concentration of the emitted negative ions is finally adjusted. In addition, in the actual use process, two or more negative ion emission needles can be selected according to actual requirements and are respectively arranged on the periphery of the matching needle, so that the generation speed and the generation amount of negative ions are further increased, and the performance of the device is improved. In addition, due to the design of the matching needle, the device is safer and more reliable in the use process, and the situations such as electrostatic beating cannot be caused. The impedance matcher may be a circuit with an adjusted impedance formed by a resistor, a capacitor, and an inductor.
The box body is filled with epoxy resin, and the lower ends of the PCB, the high-voltage generator, the negative ion emission needle and the matching needle are positioned in the epoxy resin. This structure can encapsulate PCB board, high voltage generator, anion emission needle, matching needle inside epoxy, can reduce the influence of ambient air, humidity etc. to equipment, reduces energy loss, promotes the security.
Still include the installing support, the box body fix on the installing support, power connection terminal connect on the installing support, be connected through the wire between power connection terminal and the PCB board.
The utility model provides an anion emission device, it can form high-pressure output return circuit through matching the needle, make high-voltage electric field between anion emission needle and matching needle, so adjust the impedance through the impedance matcher after with the separation of part anion outside, in the entering air, form free anion, because its electrostatic field is little, so can not cause the interference to the external world, and to the environment of anion emission device installation and the material of casing etc. all not influence the anion emission, the anion dwell time is long in the air, the transmission distance is farther. In the actual measurement process, 3-5 ten thousand negative ions are measured at a position 3m away from the emitting device.
