DETAILED DESCRIPTION

[0025] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

It should be understood that the terms "first", "second" and the like are used to describe various information in the present application, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, the "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, the "second" information can also be referred to as "first" information.

[0027] As Figures 1 to 3As shown, the preferred embodiment of the present application provides a plasma generator 100, which comprises an outer ring coil set 1 and an inner ring coil set 2, the outer ring coil set 1 is provided with a first inner layer coil 11, a first middle layer coil 12 and a first outer layer coil 13, the first inner layer coil 11, the first middle layer coil 12 and the first outer layer coil 13 are spirally wound from inside to outside along three circumferential lines with different diameters respectively, the inner ring coil set 2 is provided with a second inner layer coil 21, a second middle layer coil 22 and a second outer layer coil 23, the second inner layer coil 21, the second middle layer coil 22 and the second outer layer coil 23 are spirally wound from inside to outside along three circumferential lines with different diameters respectively; the leading end of the second inner layer coil 21 forms a negative electrode terminal B through an extension line, the trailing end of the second inner layer coil 21 is inserted into the center of the leading end of the second inner layer coil 21 through an extension line and pulled out from the center of the trailing end of the second inner layer coil 21 again, and then electrically connected with the leading end of the first inner layer coil 11, the trailing end of the first inner layer coil 11 is inserted into the center of the leading end of the first inner layer coil 11 through an extension line and pulled out from the center of the trailing end of the first inner layer coil 11 again, and then electrically connected with the trailing end of the second middle layer coil 22, the leading end of the second middle layer coil 22 is electrically connected with the trailing end of the first middle layer coil 12 through an extension line, the leading end of the first middle layer coil 12 is electrically connected with the leading end of the second outer layer coil 23 through an extension line, the trailing end of the second outer layer coil 23 is electrically connected with the leading end of the first outer layer coil 13 through an extension line, and the trailing end of the first outer layer coil 13 forms a positive electrode terminal A; the first inner layer coil 11, the first middle layer coil 12, the first outer layer coil 13, the second inner layer coil 21, the second middle layer coil 22 and the second outer layer coil 23 are all bare copper wires 3, the surface of the bare copper wire 3 is provided with a nano coating 4, and the nano coating 4 is coated with a plasma mixed glue 5. Wherein, the formation of the nano coating 4 is that the copper atoms on the surface of the bare copper wire 3 slowly jump up to form tens of thousands of square black nanocrystal lattice structures in a strong alkali environment.

[0028] Thus, according to the plasma generator of the embodiment of the present application, the outer ring coil set 1 and the inner ring coil set 2 are made by adopting the three-layer spiral coil structure design, and the current directions of the first inner layer coil 11, the first outer layer coil 13, the second inner layer coil 21 and the second outer layer coil 23 are the same, but opposite to the current directions of the first middle layer coil 12 and the second middle layer coil 22, and the nano coating 4 and the plasma mixed glue 5 are designed on the coils, when a weak voltage (such as 12V-36V) is applied, each coil generates a magnetic attractive field under the weak voltage, the plasma (such as silver ions, copper ions and zinc ions) in the plasma mixed glue 5 conducts plasma high-frequency oscillation wave under the action of the magnetic attractive field, and generates a mixed ionized gas including positive and negative ions, high-energy electrons and free radicals in the air, so that the active particles such as high-energy electrons and free radicals generated in the air decompose the pollutant molecules instantaneously, degrade the pollutants and purify the air.

[0029] It can be understood that the high-energy electrons first obtain energy from the magnetic attractive field with plasma high-frequency oscillation wave, and the energy is transferred to the molecules or atoms in the air through the magnetic attractive field excitation, and at the same time, part of the molecules become active groups; after the active groups collide with the molecules or atoms, or the active groups collide with each other, stable products are generated; the high-energy electrons can also be captured by substances with strong electron affinity such as oxygen to become negative ions; when the high-energy electrons collide with the pollutant molecules in the air, a series of physical and chemical reactions are induced, which converts the large molecular pollutants into small molecular safe substances, so as to purify the air and remove odors.

[0030] Taking the purification of automobile exhaust as an example, the exhaust detection results before and after using the plasma generator are shown in the following table.

[0031] Test item HC / 10 -6 ]]> CO / % NO / 10 -6 ]] Before use of the product 12 0.22 89 After use of the product 5 0.01 2

[0032] As shown in the above table, the contents of the three harmful gases in the automobile exhaust after using the plasma generator are significantly reduced, which also shows that the plasma generator has significant air purification ability.

[0033] For example, the first inner layer coil 11, the first middle layer coil 12, the first outer layer coil 13, the second inner layer coil 21, the second middle layer coil 22 and the second outer layer coil 23 are all right-handed spiral winding.

[0034] For example, in order to ensure the air purification ability of the plasma generator, the number of turns of the first inner layer coil 11, the first middle layer coil 12 and the first outer layer coil 13 is 120-160 turns, preferably 144 turns; the number of turns of the second inner layer coil 21, the second middle layer coil 22 and the second outer layer coil 23 is 60-100 turns, preferably 81 turns.

[0035] As Figure 4 and Figure 5 shown, another aspect of the present application provides a plasma air purification device, which comprises a housing 200 and the plasma generator 100 described above, the plasma generator 100 is installed in the housing 200, the housing 200 is provided with a power interface 300, the positive terminal A and the negative terminal B of the plasma generator 100 are connected with the DC power supply 400 through the power interface 300. Since the plasma air purification device contains the above-mentioned plasma generator, it has all the beneficial effects of the above-mentioned plasma generator, which will not be repeated here.

[0036] For example, the voltage of the DC power supply 400 is 12v-36v, which has low power consumption and high safety factor.

[0037] For example, the plasma generator 100 further comprises a resistance 500 and a capacitor 600 connected in series with each coil, the resistance 500 is 50 ohms-1000 ohms, and the capacitor 600 is 5000uf-22000uf, so that the circuit is more stable.

[0038] For example, in order to facilitate the plasma air purification device to know whether it is in working condition, the housing 200 is embedded with an LED lamp 700, which is connected in parallel with the plasma generator 100.

[0039] For example, the inside of the housing 200 is provided with multiple layers of accommodating cavities from top to bottom, one plasma generator 100 is installed in each layer of the accommodating cavities, and the plasma generators in each layer of the accommodating cavities are connected in series. Such design can facilitate the plasma air purification device to realize diversified configuration, and the more plasma generators are configured, the stronger the air purification ability is.

[0040] It should be further pointed out that when the plasma air purification device is applied to the automobile fuel system, the high-frequency oscillation wave magnetic attractive field can crack the large molecular groups of fuel into small molecular groups, so that the fuel can be fully burned, reduce the formation of carbon monoxide and carbon deposition, thereby improving the fuel efficiency and achieving the effect of energy saving and emission reduction.

[0041] The above is only the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, can make a number of improvements and substitutions, these improvements and substitutions should also be considered as the protection scope of the present application.
