Abstract

The utility model provides an anion generator with simple structure, easy manufacture and low cost. The utility model is characterized in that a copper clad plate with double surfaces is used as a polar plate, more than two needle-shaped electrodes are arranged in parallel on one surface of the polar plate in equidistance, the other surface of the polar plate is connected with a zero potential, and DC voltage from negative 2.8KV to negative 3.4KV is applied between the needle-shaped electrodes and the zero potential. The anion concentration can reach one million per cubic centimeter, ozone is hardly generated, and an electrostatic field hardly exists near an outlet. The generator, a blower and an air filter are assembled into a whole to be used as indoor air purifying equipment which can be used for preventing and curing diseases and promoting human health too.

Description

Air anion generator

The utility model relates to a kind of air negative ion generator.

The application of air anion generator improves IAQ, create the work of fresh and comfortable and the physiology and the therapeutic action of living environment and air ion, both at home and abroad the scientific worker in each field has carried out extensive and deep research ， And and various types of generator releases one after another in recent decades.And at present domestic commercially available anion generator is many according to principle of corona discharge, adopts several kilovolts to ten thousand volts high direct voltage point discharges, makes air ionization and produces anion.Because the power line directive environment the earth of the extreme emission of discharge, so near the outlet of this ionization apparatus stronger electrostatic field is arranged.Because the existence of electrostatic field has interference to some precision instrument; Wall and table top near generator in the use easily deposit dust, and be simultaneously also not fool proof.

In order to eliminate above-mentioned shortcoming, propose on discharge electrode, to apply the 6KV negative DC voltage among the British patent GB2102214, shielding is set around the discharge electrode, the current-carrying part of shielding applies and is lower than discharge electrode but is the voltage of same polarity, make electric field be limited in certain limit, there is electrostatic field hardly in surrounding environment.But need high and low two-way voltage, shielding, needle electrode are provided with more complicated respectively.

The utility model is to provide a kind of structure very simple, and processing and fabricating is easy, and cost is low, has electrostatic field hardly near outlet, and produces higher concentration anion (n under low voltage ^-=10 ⁶/ Cm ²), ozoniferous hardly air negative ion generator.

Be achieved in that the employing double face copper, at equidistant 2 the above needle electrodes that are arranged in parallel of the one side of plate, another side meets zero potential And and cover the skim insulating material on copper face, apply-2.8 to-3.4 Kilovolt Direct Currents between needle electrode and the zero potential and press, between forms extremely strong inhomogeneous field.Power line by being welded on the most advanced and sophisticated emission of needle electrode on the double face copper one side ends at the another side zero potential utmost point, electric field is limited in the less zone, so there is electrostatic field near the generator exports hardly.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1. be the structure chart of air negative ion generator;

Fig. 2. be the front view of the embodiment of anion generator electrode structure;

Fig. 3. be the front view of another embodiment of anion generator electrode structure;

Fig. 4. be the A-A profile of anion generator electrode.

As Fig. 1, Fig. 4, adopt the battery lead plate (2) that is equipped with on the framework (7) of timber or plastic production more than 1 or 1, there is Yi to Ding Ju Li And downstream direction (direction of arrow among the figure) between its plate face and is arranged in parallel.Conductive strips (3) in pole plate (2) are gone up equidistant 2 the above needle electrodes (4) that are arranged in parallel; And is connected with the high-voltage output end of high voltage source (1), another side conductive strips (5) are gone up and are covered skim insulating material (6), and the zero potential end of conductive strips (5) and high voltage source (1) is connected.Between needle electrode (4) and conductive strips (5), apply-2.8 to 3.4 Kilovolt Direct Currents and press, form extremely strong inhomogeneous field as a result around the needle electrode.When having formed electronegative ion from the air of forced draft fan (not shown) during by electric field, the air that is rich in anion is sent continuously by the generator gas vent.

Among Fig. 2, battery lead plate (2) adopts epoxide resin material as substrate, and its thickness is 1～2mm, and wide and long ratio approximates 10～20 strip double face copper.The two sides length and width periphery of plate all corrosion treatment is removed part copper layer formation insulating tape.Portion C=1.5～2.5mm is removed on its long limit, and broadside is removed partly and decided according to pole plate (2) mounting means, and the length and width size of pole plate (2) changes with generator framework size.2 above needle electrodes (4) are arranged in parallel within on the pole plate conductive strips (3), between each needle electrode (4) apart from a=10～25mm, one end of all needle electrodes (4) stretches out the edge of pole plate (2), the distance b=6～9mm at needle point and conductive strips (3) edge.

Fig. 3, be another embodiment of anion generator electrode structure, symbol is all identical with Fig. 2 with each size and arrangement mode among the figure, the two edges of pole plate (2) are all stretched out at two tips that difference only is to be welded on the needle electrode (4) on the conductive strips (3), and the distance b at needle point and conductive strips (3) edge is 6～9mm.

The utility model air negative ion generator and blower fan, air cleaner form one and can be used as indoor purifying equipment, also can be used for preventing and curing diseases and promote health. This generator and blower fan be used when wind speed be 1.5m/s, during 2900 volts of voltages, can reach 1.5 * 10 apart from outlet 30Cm place negative ion concentration⁶Individual/Cm², produce hardly ozone.
