Technical Field

The invention relates to the technical field of negative ion generators, in particular to a release head of a negative ion generator and a manufacturing method thereof.

Background

The release head of the negative ion generator mainly comprises a single-tip end point emitting needle (a first generation emitting head) and a carbon fiber bundle (a second generation emitting head). The first generation of emitter head directly connects a single point emitter needle (e.g., a single point steel needle, a silver needle or a gold needle) with a high voltage power supply, and the emitter needle discharges electricity to generate negative ions. Under lower voltage, the concentration of negative ions generated by the first generation of emission heads is small; if the voltage is increased, high negative ion concentration can be generated, but the negative ion concentration is generated along with byproducts such as ozone, nitrogen oxide radiation and the like. The second generation emitter head comprises a metal head and a carbon fiber bundle, wherein the carbon fiber bundle is inserted into a hole of the metal head and is fixed in a soldering mode. When the second generation of emitter is used, the metal head is connected with a high-voltage power supply, the carbon fiber bundle sprays electrons to the surrounding space at a high speed, and the electrons are rapidly captured by air oxygen ions to generate oxygen anions. Although the concentration of negative ions and the concentration of ozone generated by the second generation emitter can meet the requirements, the generated negative ions have large particle size and are difficult to penetrate through the blood brain barrier of a human body to exert biological effect, and carbon fiber bundles are easy to loosen and even fall off from holes of the metal head, so that the potential fault hazard exists. Moreover, the second generation of emitter generally works under the negative pressure of more than 8000V, and can ensure the release concentration of negative ions, because the strength of the carbon fiber bundle is low, the external environment is easy to influence the performance of the emitter, and the surface of the carbon fiber bundle is easy to adsorb dust and needs to be frequently cleaned, so the maintenance cycle is short, and the service life is also influenced.

The negative ions released by the existing negative ion generator can only remove solid particulate matters and PM2.5, but pollutants in the air also contain a plurality of gaseous pollutants, such as bacteria, formaldehyde, odor and gaseous VOCs organic matters, and the negative ions have an unobvious removal effect, so that the overall air purification effect of the negative ion generator is influenced.

Therefore, the existing anion releasing head has the problems of low concentration of released anions, high concentration of the released anions, unstable performance and single function, and needs to be improved.

wherein, after the step 4, the method further comprises the following steps:

and 5, sleeving a heat-shrinkable tube outside the conductive fixing device, and heating and shrinking the heat-shrinkable tube to form a whole with the conductive fixing device 2.

The conductive rod 4 was energized with a voltage of 40kV, and a tester, holding the atmospheric negative ion tester, stood right in front of the negative ion emitting head to be tested, in a direction deviated 22.5 ° to the left, in a direction deviated 22.5 ° to the right, and at positions respectively distant from the negative ion emitting head by 1m, tested the amounts of negative ions emitted from the emitting heads of one emitting head of the embodiment of the present invention and the comparative example.

4) Test results

The test results of the negative ion emitting heads of examples and comparative examples are shown in Table 1 (note: the left, middle and right in Table 1 indicate the 22.5 degree left direction, the right direction and the front direction of the negative ion emitting head, respectively).

TABLE 1

As can be seen from table 1, the negative ion concentration of the discharge head of the example of the present invention at 1m was increased as compared with the discharge head of the comparative example, indicating that the discharge head of the example of the present invention can effectively increase the negative ion discharge concentration.

2. Ozone and nitrogen oxide (NO and NO2) emissions test

1) Testing instrument

Nitrogen oxide tester-manufacturer: polyclone; the instrument model is as follows: WSQ-NOX;

ozone tester-manufacturer: polyclone; the instrument model is as follows: WSQ-O3.

2) Test conditions

Temperature: 18 deg.C

Relative humidity: 18 percent;

PM2.5：30μg/m2

3) test procedure

A tester holds a nitrogen oxide tester or an ozone tester by hands, respectively stands in the positions which are respectively in the positive front, the left side and the right side of the negative ion release head to be tested and are deviated from the 22.5-degree directions and are respectively 1m away from the negative ion release head, and tests the concentration of ozone and nitrogen oxide released by the negative ion release head to be tested.

4) Test results

The results of the tests of the ozone and nitrogen oxide release amounts (total amount of NO and NO2 released) of the negative ion emitting heads of the examples are shown in table 2.

TABLE 2

As can be seen from table 2, the composite negative ion emitting heads of examples of the present invention did not emit nitrogen oxides and the amount of ozone emitted was reduced relative to the emitting heads of comparative examples, as compared to the emitting heads of comparative examples.

3. PM2.5 and Formaldehyde reduction test

1) Testing instrument

Hand-held tester-manufacturer: hua Si Tong; the instrument model is as follows: WST-3200 Pro.

2) Test conditions

Temperature: 18 deg.C

Relative humidity: 18 percent;

PM2.5：100μg/m2

formaldehyde: 0.5mg/m3

3) Test procedure

The conductive rod 4 was connected to a voltage of 6KV, and the formaldehyde tester was fixed at a position 1m from the negative ion emitting head just in front of the emitting head, to test the effects of the emitting heads of the one emitting head of the embodiment of the present invention and the comparative emitting head of the present invention in degrading formaldehyde and removing PM 2.5.

4) Test results

The results of the formaldehyde and PM2.5 removal tests of the examples and comparative examples are shown in table 1 (conditions before decontamination are identical, comparative effect after 30min decontamination).

TABLE 3

Table 3 can see that the removal effect of the release head of the embodiment of the present invention on PM2.5 and formaldehyde of 1m is enhanced compared with the release head of the comparative example, which shows that PM2.5 particulate matter and gaseous pollutants can be effectively removed by adding the functional layer and the electron increasing layer in the release head of the embodiment of the present invention.
