[0041] Example 1

[0042] like Figure 1 The first embodiment of the method for manufacturing an induced plasma generating device of the present invention is shown, comprising the following steps:

[0043] S1. Provide a plasma generating device 1 and an ion-inducing release structure 2.

[0044] The plasma generating device 1 is a plasma generator, and the induced ion release structure 2 includes at least two carbon fiber bundles. In this embodiment, the induced ion release structure 2 includes two carbon fiber bundles, which are used to release positive ions and negative ions respectively, and are also used to induce the ionization structure 3 to generate a higher amount of ions.

[0045] S2. After step S1, pre-treat the induced ion release structure 2. The pre-treating includes: sharpening one end of the carbon fiber bundle to form a tip structure.

[0046] S3. Prepare ionization structure 3: provide a foam metal mesh, and coat the foam metal mesh with an oxidized metal coating or a nano-scale oxidized metal coating to form an ionization structure 3. In this embodiment, the ionization structure 3 includes two foam metal meshes coated with coatings, which are respectively used to generate a positive electrode and a negative electrode, and the generated positive electrode and the negative electrode form ionization to generate an electric field.

[0047] Specifically, the foam metal mesh is a foam metal mesh composed of any one or more of nickel, copper, iron, tungsten, magnesium, manganese, silver, platinum, cobalt, and titanium. In this embodiment, the mesh size of the foam metal mesh is 40 meshes or more.

[0048] Specifically, the metal oxide coating is a metal oxide coating composed of any one or more of nickel oxide, copper oxide, iron oxide, tungsten oxide, magnesium oxide, manganese oxide, silver oxide, platinum oxide, cobalt oxide, and titanium oxide; the material selection of the nano-scale metal oxide coating is similar to that of the metal oxide coating. In this embodiment, the coating of the metal oxide coating or the nano-scale metal oxide coating can be processed by spraying, electroplating, etc., which is not limited here.

[0049] It should be noted that the material combination of the foam metal mesh and the coating can be matched according to actual functional requirements. For example, coating the foam copper mesh with a silver oxide coating can not only achieve sterilization and air purification, but also use titanium oxide to decompose ozone and further reduce the generation of ozone.

[0050] S4. Overlap the induced ion release structure 2 obtained in step S2 and the ionization structure 3 obtained in step S3 through a bracket 4, with the induced ion release structure 2 with one end being sharpened facing the direction of air flow, and the ionization structure 3 being located between the induced ion release structures 2.

[0051] Specifically, the bracket 4 includes a first plate 41 and a second plate 42 detachably connected to the first plate 41. The first plate 41 and the second plate 42 are both provided with a first clamping portion 43 for mounting the ionization structure 3. The first plate 41 is also provided with a second clamping portion 44 for mounting the induced ion release structure 2; specifically, the second clamping portion 44 is located near the edge of the first plate 41.

[0052] Specifically, step S4 includes the following steps:

[0053] S41. Connect two coated foam metal meshes to the first clamping portion 43;

[0054] S42. After step S41, the two carbon fiber bundles are clamped at the second clamping portion 44, and the tip structure of the carbon fiber bundle is arranged toward the direction of air flow;

[0055] S43. After step S42, assemble the first plate 41 and the second plate 42.

[0056] S5. After step S4, the induced ion release structure 2 and the ionization structure 3 are respectively connected to the plasma generating device 1 to form an induced plasma generating device.

[0057] Step S5 specifically includes: connecting the foam metal mesh for generating the positive electrode and the carbon fiber bundle for releasing positive ions to the positive electrode contact of the boost module of the plasma generator 1 through a wire; and connecting the foam metal mesh for generating the negative electrode and the carbon fiber bundle for releasing negative ions to the negative electrode contact of the boost module of the plasma generator 1 through a wire. It should be noted that the foam metal mesh for generating the positive electrode and the carbon fiber bundle for releasing positive ions are connected to the same potential of the plasma generator 1, and the foam metal mesh for generating the negative electrode and the carbon fiber bundle for releasing negative ions are connected to the same potential of the plasma generator 1; in addition, the positive electrode contact and the negative electrode contact can be located outside the plasma generator 1 or inside the plasma generator 1. The carbon fiber bundle for releasing positive ions is adjacent to the foam metal mesh for generating the positive electrode, and the carbon fiber bundle for releasing negative ions is adjacent to the foam metal mesh for generating the negative electrode.

[0058] S6. After step S5, the ion amount and ozone amount of the induced plasma generating device are detected.

[0059] Step 6 specifically includes the following steps:

[0060] S61 provides a power supply 6, and connects the plasma generating device 1 to the power supply 6;

[0061] S62. Provide a fan, and then install the induced plasma generating device at the air outlet of the fan;

[0062] S63 provides an air positive and negative ion tester, and places the air positive and negative ion tester at the initial test point at the front end of the induced plasma generating device; specifically, the horizontal distance between the initial test point and the air outlet of the fan is 10cm;

[0063] S64. Start the power supply, the fan and the air positive and negative ion tester, and read the value 5 to 10 seconds after the air positive and negative ion tester displays the value. Repeat this step at least three times, and then take the average of the three readings;

[0064] S65. Move the air positive and negative ion tester away from the initial test point and test again; specifically, test at 20, 30, and 40 cm away from the air outlet of the fan;

[0065] S66. Use an ozone monitor to detect ozone levels.

[0066] In this embodiment, the KT-401 Air Ion Tester is used for testing. The maximum readable value of the instrument is 1999×10 4 .like Figure 2 As shown, the induced plasma generator can produce higher ion quantity in a larger range compared with the combined plasma tube, foam metal mesh, and carbon fiber bundle. In addition, the amount of ozone produced by the induced plasma generator is 0.033ppm, with no ozone smell, which can be basically ignored; while the amount of ozone produced by the combined plasma tube, foam metal mesh, and carbon fiber bundle is between 0.2 and 1ppm, and has a strong ozone smell; thus, it can be concluded that the amount of ozone produced by the induced plasma generator is significantly lower than that of the combined plasma tube, foam metal mesh, and carbon fiber bundle.

[0067] Example 2

[0068] This embodiment is similar to Embodiment 1, except that step S3 specifically includes the following steps:

[0069] S31. Preparing a substrate slurry using a carrier metal;

[0070] S32. Add metal oxide material to the substrate slurry and mix to form a network structure to obtain an ionized structure 3.

[0071] Example 3

[0072] like Figures 3 to 7 The figure shows a first embodiment of an induced plasma generating device of the present invention, comprising a plasma generating device 1 and an induced ion release structure 2 and an ionization structure 3 which are communicatively connected to the plasma generating device 1. The ionization structure 3 is overlapped with the induced ion release structure 2 via a bracket 4, and the ionization structure 3 is located between the induced ion release structures 2.

[0073] The bracket 4 includes a first plate 41, a second plate 42, a connecting piece 45, and a connecting block 46. The first plate 41, the second plate 42, and the connecting piece 45 are all connected to the connecting block 46. The first plate 41 and the second plate 42 are both provided with a first clamping portion 43 for fixing the ionization structure 3. The first plate 41 is also provided with a second clamping portion 44 for fixing the induced ion release structure 2. Figure 3 , Figure 6 and Figure 7As shown, the first plate 41, the second plate 42, and the connecting piece 45 are arranged parallel to each other, and the connecting block 46 is connected to both ends of the first plate 41 and also connected to both ends of the second plate 42. In this embodiment, at least two second clamping parts 44 and at least two first clamping parts 43 are provided, and the second clamping part 44 is located at the edge of the first plate 41. Specifically, the second clamping part 44 is a through-hole structure; a plurality of parallel strip structures are provided on the first plate 41, and the structure of the second plate 42 is similar to that of the first plate 41. A plurality of parallel strip structures are also provided on the second plate 42, and the first clamping part 43 is a gap formed between adjacent strip structures. In addition, in this embodiment, the connecting piece 45 is an annular structure or a rectangular structure, which can facilitate the overlap of the bracket 4 with any air purifier or fan.

[0074] In addition, the induction plasma generating device further comprises a power supply 6, which is electrically connected to the plasma generating device 1. Figure 4 shown.

[0075] like Figures 3 to 5 As shown, in this embodiment, the induced ion release structure 2 includes two carbon fiber bundles, which are clamped at the through-hole structure, and the ionization structure 3 includes two foam metal meshes, which are clamped at the gap, and the foam metal mesh is located between the two carbon fiber bundles. The two foam metal meshes are arranged horizontally with each other, such as Figure 4 As shown; the two foam metal meshes can also be arranged at an angle, such as Figure 5 shown.

[0076] When using, Figure 5 As shown, when the wind blows toward the inductive plasma generator, the wind speed generated forms a jet, which is the jet principle. When the air passes between the two foam metal meshes, under the jet principle, the two foam metal meshes are ionized to generate an electric field, which can purify bacteria, organic harmful gases (VOC), etc. When the air flows through the bracket 4, the two foam metal meshes and the two carbon fiber bundles are located on both sides of the flowing air, which can reduce wind resistance and prevent the air output from attenuating. In addition, by setting the carbon fiber bundle to induce the foam metal mesh, the generation of ions can be greatly increased, and only a trace amount of ozone is generated in the process, which improves the purification effect and further protects the health of the user. In addition, the number of inductive plasma generators can be increased according to the actual performance to ensure that the bacteria are killed and the organic harmful gases are decomposed, further improving the air purification effect.

[0077] Example 4

[0078] This embodiment is similar to Embodiment 3, except that Figure 8 and Fig. 9As shown, the induced plasma generating device in this embodiment further includes an air guide cover 5, on which an air outlet 51 and an air inlet 52 are provided. The plasma generating device 1 is arranged in the air guide cover 5, and the air guide cover 5 is detachably connected to the air outlet 51.

[0079] like Fig. 9 As shown, a first connecting column 53 for connecting to the bracket 4 is connected inside the air guide 5, and a second connecting column 54 for connecting to the plasma generator 1 is also connected inside the air guide 5. A cut surface is provided on the second connecting column 54, which can be easily fixed to the plasma generator 1. Specifically, the bracket 4 and the air outlet 51 are connected by screws that pass through the connecting piece 45 and the first connecting column 53 in sequence. Convex rings are provided at both ends of the plasma generator 1, and the plasma generator 1 and the air guide 5 are connected by screws that pass through the convex ring and the second connecting column 54 in sequence. In this embodiment, the air guide 5 is cylindrical. It should be noted that the air guide 5 can also be set to other structures such as rectangular and conical, which are not limited here.

[0080] When in use, the air inlet 52 of the air guide cover 5 is connected to an air purifier or a fan, and the air blown out by the air purifier or the fan flows out from the air outlet 51 after passing through the induced plasma generating device, thereby achieving a purification effect.
