Abstract

The utility model discloses a negative oxygen ion generator, which is composed of a rectification circuit, a high voltage generating circuit, a spray point, a housing, a double-faced electronic circuit board, etc. Because a voltage dependent resistor RV is utilized to connect a high voltage output end with mains supply in the high voltage generating circuit, the generating efficiency and the concentration of the negative oxygen ions are enhanced. The mains supply is isolated simultaneously, and people's safety is ensured. In addition, because distributed capacitance which is formed by the double-faced circuit board is utilized, the rectified output high voltage can be filtered. The output high voltage is caused not only steady but increased as well. The generating efficiency and the concentration of the negative oxygen ions are further enhanced. The negative oxygen ion generator has the advantages of artful design, simple circuit, and low cost.

Description

Negative oxygen ion generator

The utility model relates to a kind of generator, particularly a kind of negative oxygen ion generator.

Existing anion generator effect not ideal enough (negative ion concentration is not enough); And circuit is complicated, and volume is also bigger, the cost height.In addition, the high-pressure side of these anion generator mesohigh generators must have an end ground connection or connect city's power line, and the luminous efficiency of anion could improve, but such connection is safe and reliable inadequately, and it is also convenient inadequately to use.

The purpose of this utility model is to avoid above-mentioned existing not enough place and a kind of negative oxygen luminous efficiency height is provided, and concentration is enough, and circuit simple, design negative oxygen ion generator cleverly.

The utility model can reach by following measure: the utility model is by rectification circuit, high-pressure generating circuit, spray point, housing, compositions such as electronic circuit board, it is characterized in that: the output of rectifier bridge Z is joined by the anode of capacitor C 1 and controllable silicon SCR in resistance R 1 and the high-pressure generating circuit in the rectification circuit, and by resistance R 1, R2 and capacitor C 2, the end of bidirectional diode D1 joins, the other end of D1 and the grid of controllable silicon SCR join, the pin of capacitor C 1 and step-up transformer B joins, the elementary pin of B joins by piezo-resistance RV and secondary pin, and the secondary pin of B joins by diode D2 and spray point.

The utility model can also reach by following measure: it is characterized in that: electronic circuit board is a double-sided wiring board, and one side is needle plate J1, and another side is pole plate J2, on the needle plate J1 spray point is housed, and the pin of pole plate J2 and step-up transformer and piezo-resistance RV join.Form a distributed capacitance between needle plate J1 and the pole plate J2, capacitance is 15～350PF.The breakover voltage of piezo-resistance RV is 300～3000 volts.

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

With reference to Fig. 1, Fig. 2, the utility model is made up of rectification circuit 1, high-pressure generating circuit 2, spray point 3, housing 4, double-side electronic wiring board 5 etc.Double-side electronic wiring board 5 is divided into needle plate J1 and pole plate J2 two sides, and the centre is an insulating barrier 6; Five spray points are contained on the needle plate J1, and outside the outstanding housing 4; And pole plate J2 simultaneously is equipped with electronic component.Total volume little (only being equivalent to the cigarette case size half), manufacturing process is simple.

With reference to Fig. 3, rectification circuit 1 comprises rectifier bridge Z etc.; High-pressure generating circuit comprises resistance R 1, R2, capacitor C 1, C2, controllable silicon SCR, bidirectional diode D1, step-up transformer B, diode D2, piezo-resistance RV etc.

The alternating current 220V civil power obtains the all-wave pulsating dc voltage after rectifier bridge Z rectification, charged to C1 by R1; On the other hand, charge to C2 through R2, when C2 is charged to the trigger voltage of diac D5, trigger the controllable silicon SCR conducting, the C1 that has been full of electricity is through the elementary discharge of SCR to step-up transformer B, and at the high pressure of secondary formation more than 10,000 volts, this high pressure is given the needle plate J1 that is welded with 5 pins through D2 rectification output negative voltage, form the high pressure negative electric field over the ground in the needle point place, ionized air produces negative oxygen ion.The effect of piezo-resistance RV(breakover voltage 300～3000V) is that an end of high pressure and city's electric wire are linked, and strengthens angrily ion luminous efficiency and concentration greatly; Isolate civil power and needle plate simultaneously, guarantee personal safety.Needle plate J1 and pole plate J2 can form the electric capacity of 15～350PF, and the rectification of D2 output high pressure is carried out filtering, and the high pressure that makes needle plate J1 not only steadily but also be improved has further improved negative oxygen ion luminous efficiency and concentration.

The utility model has following advantage compared to existing technology: negative oxygen ion luminous efficiency height, enough, safe and reliable, easy to use, the little power consumption of concentration; And design ingenious, the circuit advantages of simple, cost is low, and is easy to manufacture, is suitable for the various occasions that need to produce negative oxygen ions.
