Abstract

The utility model relates to a high-efficiency anion generator which is used in the medical treatment. The utility model improves the shortages of the prior anion generators which have low efficiency, generate the ozone by the discharging and high concentration. On the basis of the original anion generators, the utility model reduces the electric field intensity between the two poles. The utility model inflicts the cathode of the vertical current voltage U<1> on the discharging needle and makes the anion which are emitted by the U<1> are blown from the anode board holes by the anion wind which is generated in the U<1>, The anion enter the air and form a loop with the grounded anode, thereby elevating the efficiency of the anion generator from the original less than 10 percent to above 90 percent, also because the utility model basically not generate the ozone, the utility model has practical use value.

Description

A kind of high efficiency anion generator

(1) technical field

The utility model relates to health care, and particularly a kind of air that makes produces anion, helps the electronic equipments of health care.

(2) background technology

At present, the anion generator of selling on the market all is that voltage is applied on the positive and negative plate of discharge electrode, the anion overwhelming majority that it produced is all absorbed by positive plate, have only the minute quantity anion from anodal plate hole, to blow out, therefore its efficient is extremely low, and electric field strength is higher between positive/negative plate, and discharge generation ozone, nitrous oxides concentration are bigger, therefore anion generator is used and popularization is restricted.

(3) summary of the invention

The purpose of this utility model is at the above-mentioned background technology, and a kind of anion generator that can produce the anionic wind of high concentration expeditiously is provided.

The air negative ion generator that the utility model provides is made up of DC high-voltage power supply and anion launcher.Wherein anion launcher is made of negative plate that has spray point and the positive plate that has venthole; And the step-up transformer that DC high-voltage power supply is exported by double winding boosts input ac voltage into behind u1 and the u2 respectively, through rectifier rectification, difference output dc voltage U1 and U2, wherein the both positive and negative polarity of direct voltage U2 connects the positive plate and the negative plate of anion launcher respectively, constitutes discharge loop; And the negative pole of direct voltage U1 is connected on the negative plate of anion launcher, and plus earth constitutes the loop by atmosphere.

Above-mentioned anion generator, after the energising, under direct voltage U2 electric field action, because the point effect of the spray point of negative plate makes near the air generation ionization of spray point, produces cation and anion, wherein cation is attracted neutralization by spray point, anion is then repelled by negative electric field, flies to positive plate, forms " ion wind ".Because of the negative pole of another direct voltage U1 also is connected on the negative plate of reflector, be that U1 produces anion emission and created condition by the air after the U2 ionization.Because of the positive pole of U1 does not directly join with the positive plate of reflector, but the earth and air and negative plate formation loop by joining with it, so the anion that the U1 electric field produces is just under the forcing to take part of " ion wind " that the U2 electric field produces, from the venthole of positive plate, fly out, be diffused in the air, absorbed by the earth, thereby constitute the loop.Dust is also taken to ground by anion in the air, plays the air cleaning effect, also just plays medical care effect if the people is drawn onto anion air.

Fig. 1 is the structural upright schematic diagram (broken section) of an embodiment of the present utility model;

Fig. 2 is the circuit diagram of Fig. 1 anion generator.

(4) embodiment

In conjunction with Fig. 1 and Fig. 2, the utility model anion generator is the casing made from insulating material (available plastics) 2 (front and rear casing has air-vent) with the front and rear part up and down, the anterior positive plate 6 that the anion launcher of being manufactured by copper coin is installed, have equally distributed venthole 7 on the positive plate, in the casing, the negative plate 3 that parallel installation with positive plate is manufactured by copper coin, the spray point of in the welding of the center of each venthole of corresponding positive plate on this negative plate, manufacturing 5 by stainless steel wire, have air admission hole 4 between the adjacent spray point, enter between the positive/negative plate for extraneous air.DC high-voltage power supply (not drawing among Fig. 1) is installed at the rear portion in the casing, and this power supply joins with input ac voltage by lead and plug 1.The step-up transformer B of DC high-voltage power supply is double winding output, input ac voltage (power frequency or high frequency) boosts respectively through transformer B and is u1 and u2, this output AC voltage is by rectifier Z halfwave rectifier, difference output dc voltage U1 and U2, wherein direct voltage U2 both positive and negative polarity is added in respectively on the positive/negative plate of anion launcher, constitutes discharge loop; And the negative pole of direct voltage U1 connects the negative plate of anion generator, and plus earth constitutes the loop by atmosphere.

Example: the spray point diameter of this anion generator is taked 0.5 millimeter, 10 millimeters of 5 millimeters spacings of length, the needle point angle is no more than 60 °, 8 millimeters of discharge needle point and negative plate spacings, 8 millimeters of venthole diameters on the positive plate, 8 millimeters of negative plate air admission hole diameters, transformer output AC voltage u1 is 10KV, u2 is that (VD after the rectification is U1-14KV to 1KV, U2-1.4KV).When the pole plate area was got 250 square centimeters, its anion emission underpower 1W can satisfy the needs of 30 square metres of careats.

Technical parameters such as each component specification of above-mentioned anion generator, size and V1V2 voltage can use field requirement design according to difference.

Anion generator of the present utility model through facts have proved, adopts " anionic wind " of the anion generator generation of foregoing circuit, the concentration height, and the efficient height has practical value (essentially no ozone and nitrogen oxide).

Because this anion generator also has dedusting concurrently, eliminates static, so can be widely used in industrial and agricultural production.
