Abstract

The utility model relates to a high safety, high concentration air anion generator without ozone. Primarily, one or a plurality of resistors with high resistance are connected in series with the position between the high-voltage output end of a high-voltage generating circuit and an emission electrode, and the emission electrode is exposed to the outer part of a casing. The anion generator of the utility model effectively reserves various functions and advantages of the prior art; at the same time, the anion generator has the advantages of convenient use, simple structure and high safety and reliability, the generated air anion has high concentration, and the ozone can not be generated. Thus, the utility model effectively overcomes the defects of the prior art, which is the quite ideal air anion generator.

Description

The ozone free air negative ion generator of high security, high concentration

The utility model relate to a kind of can ozoniferous air negative ion generator, specifically refer to the ozone free air negative ion generator of a kind of high security, high concentration.

Along with improving constantly of people's living standard, the use of air negative ion generator is also constantly popularized.Existing air negative ion generator mainly is to utilize principle of corona discharge, the negative high voltage ionized air molecule that promptly utilizes air negative ion generator and produced, to form the cation and the electronegative electronics of positively charged, thereby make the electronegative negative aeroion of generation in the air, it is early stage that air negative ion generator adopted is bipolar electrode, when its shortcoming is to produce negative aeroion, can produce harmful ozone, existing for this reason air negative ion generator adopts the single electrode mode mostly, and its voltage brought up to about 10,000 volts, thereby reduced the generation of ozone effectively, and make the enough negative aeroions of generation in the unit space, but because its voltage is higher, cause the danger of electric shock easily to the user, for guaranteeing safety, existing air negative ion generator all is placed in emission electrode in the good plastic jacket of insulation, and the negative aeroion that is produced is overflowed from the aperture of plastic jacket, or adopt fan to blow out by force, because the use of above-mentioned north material cover, the air-anion concentration that makes existing air negative ion generator be produced are affected (general) all at 3,000,000/cubic centimetre.

The purpose of this utility model just is to provide a kind of novel high security, the ozone free air negative ion generator of high concentration; with by its uniqueness; and simple and effective safety guard; make its various functions and advantage of both having kept prior art effectively, it is high and can ozoniferous advantage to have simultaneously air-anion concentration easy to use, simple in structure, safe and reliable, that produced again.

The purpose of this utility model realizes in the following manner: the ozone free air negative ion generator of a kind of high security, high concentration, mainly form by high-pressure generating circuit, emission electrode and housing, it is characterized in that between the high-voltage output end and emission electrode of high-pressure generating circuit, be in series with one or many high resistance measurements, above-mentioned emission electrode exposes outside housing.

Adopt high security of the present utility model; the ozone free air negative ion generator of high concentration; because it is unique to have adopted; and simple and effective safety guard; promptly between the high-voltage output end and emission electrode of high-pressure generating circuit; be in series with one or many high resistance measurements; make it both keep the various functions and the advantage of prior art effectively; have simultaneously easy to use again; simple in structure; safe and reliable; the air-anion concentration height that is produced; can not produce ozone and broad-spectrum advantage; thereby having overcome the deficiencies in the prior art effectively, is a kind of very desirable ozone free air negative ion generator.

Description of drawings.

Fig. 1 is a kind of example structure schematic diagram of the present utility model;

Fig. 2 is a kind of embodiment circuit diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described.

As shown in the figure, the ozone free air negative ion generator of high security of the present utility model, high concentration, mainly form by high-pressure generating circuit (3), emission electrode (2) and housing (1), between the high-voltage output end (4) and emission electrode (2) of high-pressure generating circuit (3), (to select resistance for use be the resistance of 200 megaohms to this resistance in an embodiment to be in series with one or many high resistance measurements (5), or series connection back resistance reaches the resistor group of 200 megaohms), above-mentioned emission electrode (2) exposes outside housing (1).Above-mentioned high-pressure generating circuit can adopt the circuit of various air negative ion generators of the prior art.

Basic principle of the present utility model is: because high-pressure generating circuit will produce the high pressure that 10,000 volts of left sides have when energising is used, and by joining emission electrode ionized air with it, produce negative aeroion, when people's (or poultry) with it contact or near the time will cause getting an electric shock and cause damage, thereby the emission electrode of existing air negative ion generator must install in housing; When between its high-voltage output end and emission electrode, being in series with high resistance measurement, when people and animals contact with it or near the time because the voltage instantaneous of high-voltage output end drops to the resistance two ends of high value, the voltage that the contactee bore is then reduced to below the safe voltage.Owing to adopted above-mentioned holding circuit; the emission electrode of band high pressure need not to be placed in the housing of air negative ion generator; and can directly expose outside generator body; thereby reduced " shielding " effect of housing effectively; its air-anion concentration that produces is increased considerably; show after tested; adopt the concentration of the negative aeroion that air negative ion generator produced of this structure can reach more than 7,000,000/cubic centimetre; ozone content does not have electrical sensation and feels then less than 0.2 milligram/cubic metre when the people contacts the high pressure emission electrode.

Technology of the present utility model can be applicable on the various air negative ion generator circuit.
