[0050] like Figures 1 to 7 As shown, according to an embodiment of the present utility model, an ion generating device 100 is proposed, which includes an insulating frame 10, a first electrode 40, a second electrode 20 and a cover 30. The first electrode 40 is connected to the insulating frame 10, and the first electrode 40 and the insulating frame 10 enclose an ionization space 50. The second electrode 20 is arranged in the ionization space 50 and is arranged opposite to the first electrode 40. The second electrode 20 includes a base portion 21 and an electrode portion 22 connected at an angle. The base portion 21 is connected to the insulating frame 10, and the electrode portion 22 is spaced apart from the first electrode 40. The electrode portion 22 can generate a non-equilibrium electric field with the first electrode 40 when a voltage is applied, so as to utilize the non-equilibrium electric field to ionize the air in the ionization space 50 to form plasma.

[0051] Specifically, in the present application, the insulating frame 10 is connected and fixed to the first electrode 40, and the connection method includes but is not limited to bonding, clamping or connection via fasteners. There is a separation space between the insulating frame 10 and the first electrode 40, and the separation space is the ionization space 50. The second electrode 20 is arranged in the ionization space 50 and is connected and fixed to the insulating frame 10, and the connection and fixing method includes but is not limited to bonding, clamping or connection via fasteners.

[0052] The base portion 21 of the second electrode 20 is fixed to the insulating frame 10, and the electrode portion 22 of the second electrode 20 extends toward the side closer to the first electrode 40, with the electrode portion 22 spaced apart from the first electrode 40. The cover 30 is disposed on the side not facing the first electrode 40 to insulate the base portion 21 from the first electrode 40.

[0053] When the ion generating device 100 is in use, the first electrode 40 and the second electrode 20 are electrically connected to the power supply system (for example, the second electrode 20 is connected to the positive electrode of the power supply system, and the first electrode 40 is grounded), high voltage is applied between the first electrode 40 and the second electrode 20, and a non-balanced electric field is generated between the electrode portion 22 and the first electrode 40, so as to utilize the non-balanced electric field to ionize the air in the ionization space 50 to form a low-temperature plasma.

[0054] The ion generator 100 of the present invention can achieve stable, continuous self-sustaining discharge within its structure in an air environment, achieving the goal of stable plasma generation, effectively oxidizing organic matter in the air, effectively destroying the DNA of bacteria and viruses, and effectively charging passing particulate matter and gas molecules in the air. At the same time, discharge to the outside world and sparking are largely avoided.

[0055] In some embodiments of the present invention, the ion generating device 100 may further include a cover 30, which is disposed in the ionization space 50 and between the base 21 and the first electrode 40. The cover 30 is connected to the side of the base 21 facing the first electrode 40 and shields the side of the base 21 facing the first electrode 40. The cover 30 shields the base 21, thereby ensuring insulation between the base and the first electrode 40.

[0056] In some embodiments of the present invention, the electrode portion 22 is a triangular structure, one side of the triangular structure is connected to the base portion 21, and the vertex of the triangular structure opposite to the base portion 21 is the electrode tip. The electrode tip can form a non-equilibrium electric field with the first electrode 40 when a voltage is applied, and use the non-equilibrium electric field to perform self-sustaining discharge to ionize the air in the ionization space to form plasma.

[0057] Specifically, when the ion generating device 100 is in use, a non-equilibrium electric field is generated between the first electrode 40 and the electrode tip of the electrode portion 22, so as to utilize the non-equilibrium electric field to ionize the air in the ionization space 50 to form a low-temperature plasma; the non-equilibrium electric field can generate a corona at the electrode tip of the second electrode 20, and the corona is generated by the release of photons by electron transition after the air near the electrode tip is plasmatized.

[0058] By setting the electrode portion 22 into a triangular structure and setting one corner of the triangular structure close to the first electrode 40 to form an electrode tip, the position of the first electrode 40 relative to the second electrode 20 can be controlled, thereby enabling a continuous and stable non-uniform electric field to be generated in the ionization space 50 to meet the use requirements of the ion generating device 100.

[0059] It should be noted that the triangular electrode portion 22 can be an isosceles triangle or a non-isosceles triangle. In the present application, the triangular electrode portion 22 is an isosceles triangle, and the waists on both sides of the electrode tip are equal. By setting the triangular structure to an isosceles triangle, a continuous and stable non-uniform electric field can be formed to meet the use requirements of the ion generating device 100.

[0060] In some embodiments of the present invention, the angle of the electrode tip ranges from 10° to 120°.

[0061] Specifically, the electrode portion 22 has a triangular structure, and is an isosceles triangle structure, with waists on both sides of the electrode tip being set equal. The angle of the electrode tip refers to the angle between the waists on both sides of the electrode tip. By setting the angle of the electrode tip, and thus reasonably setting the angle of the electrode tip, a stable and continuous self-sustaining discharge can be achieved between the electrode tip and the first electrode 40, forming a corona field, achieving the purpose of stable plasma generation, effectively oxidizing organic matter in the air, effectively destroying the DNA of bacteria and viruses, and effectively charging passing particulate matter and gas molecules in the air.

[0062] It should be noted that the angle of the electrode tip can specifically be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110° or 120°, etc.

[0063] In some embodiments of the present invention, along the direction from the cover 30 to the first electrode 40 , the height of the electrode portion 22 is in the range of 0.1 mm to 100 mm.

[0064] Specifically, the base portion 21 is spaced apart from the first electrode 40 and is arranged parallel to each other. In the direction from the cover 30 to the first electrode 40, the height of the electrode portion 22 refers to the length of the electrode portion 22 between the base portion 21 and the first electrode 40. Figure 6 As shown, Figure 6In the figure, b4 is the height of the electrode portion 22. By reasonably setting the height of the electrode portion 22, the height of the electrode portion 22 can meet the requirements of the ion generating device 100, so that stable and continuous self-sustaining discharge can be achieved between the electrode tip and the first electrode 40, forming a corona field, achieving the purpose of stably generating plasma, effectively oxidizing organic matter in the air, effectively destroying the DNA of bacteria and viruses, and effectively charging the passing particulate matter and gas molecules in the air.

[0065] It should be pointed out that, along the direction from the cover 30 to the first electrode 40, the height of the electrode portion 22 can be 0.1mm, 0.5mm, 1mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm or 100mm, etc.

[0066] In some embodiments of the present invention, the distance between the electrode portion 22 and the first electrode 40 (eg Figure 6 As shown, Figure 6 b5 is the distance between the electrode portion 22 and the first electrode 40) in the range of 10 mm to 70 mm. Specifically, when the ion device is in use, high voltage is applied between the first electrode 40 and the second electrode 20, and a continuous and stable non-uniform electric field is formed between the electrode portion 22 of the second electrode 20 and the first electrode 40. By reasonably setting the distance between the electrode portion 22 and the first electrode 40, the size between the electrode portion 22 and the first electrode 40 can meet the requirements of the ion generating device 100, thereby enabling stable and continuous self-sustaining discharge to be achieved between the electrode tip and the first electrode 40, forming a corona field, achieving the purpose of stable plasma generation, effectively oxidizing organic matter in the air, effectively destroying the DNA of bacteria and viruses, and effectively charging passing particulate matter and gas molecules in the air.

[0067] It should be noted that the distance between the electrode portion 22 and the first electrode 40 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm or 70 mm.

[0068] In some embodiments of the present invention, the second electrode 20 is a plate-like member, which is formed into a base portion 21 and an electrode portion 22 by bending. The base portion 21 is perpendicular to the electrode portion 22. The thickness of the plate-like member (e.g. Figure 6 As shown, Figure 6 Where b1 is the thickness of the base portion 21, b2 is the thickness of the electrode portion 22, and b1 is equal to b2) in the range of 0.1 mm to 3 mm.

[0069] Specifically, the second electrode 20 is configured as a plate-like member, and is bent to form a base portion 21 and an electrode portion 22 that are perpendicular to each other. The base portion 21 and the electrode portion 22 are an integrated structure. By configuring the base portion 21 and the electrode portion 22 as an integrated structure, the connection strength between the base portion 21 and the electrode portion 22 is improved, and at the same time, processing and manufacturing are facilitated, which can effectively improve the efficiency of processing and manufacturing.

[0070] In addition, the thickness of the plate-like member is set so that the second electrode 20 as a plate-like member can have sufficient structural strength, thereby ensuring the structural stability of the second electrode 20, and further allowing the second electrode 20 to form a non-uniform electric field with the first electrode 40 at a preset position.

[0071] It should be noted that the thickness of the second electrode 20 which is a plate-shaped member may be 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm.

[0072] In addition, the second electrode 20 is made of a corrosion-resistant alloy, thereby increasing the service life of the second electrode 20 .

[0073] In some embodiments of the present invention, the width of the base portion 21 (eg Figure 6 As shown, Figure 6 b3 is the width of the base portion 21) in the range of 0 mm to 100 mm. Specifically, the base portion 21 supports the electrode portion 22. By reasonably setting the width of the base portion 21, the base portion 21 can ensure good support performance for the electrode portion 22.

[0074] It should be pointed out that the width of the base portion 21 can be 0.1mm, 0.5mm, 1mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm or 100mm, etc.

[0075] In addition, in the arrangement direction of the two openings 51 of the ionization space 50, the cover 30 is arranged closer to the opening 51 than the base portion 21, that is, in the arrangement direction of the two openings 51 of the ionization space 50, the cover 30 protrudes from the base portion 21, and the height of the protrusion (such as Figure 6 As shown, Figure 6 b6 (height of the protrusion) is greater than 0 mm, so that the base portion 21 can be insulated.

[0076] In some embodiments of the present invention, the ionization space 50 includes two openings 51 arranged opposite to each other, and the arrangement direction of the second electrode 20 and the first electrode 40 is arranged at an angle to the arrangement direction of the two openings 51 (for example, 60°, 90°, or 135°). Figure 6 As shown, Figure 6 b8 is the distance between the base portion 21 and the opening 51) is greater than or equal to 2 mm, and / or the minimum distance between the electrode portion 22 and the opening 51 (such as Figure 5 As shown, Figure 5 where a1 is the distance between the electrode portion 22 and the opening 51 ) is greater than or equal to 2 mm.

[0077] By setting the distance between the base portion 21 and the opening 51 , and the distance between the electrode portion 22 and the opening 51 , the base portion 21 and the opening 51 can be insulated, thereby greatly avoiding discharge and sparking to the outside world.

[0078] It should be pointed out that the minimum distance between the base portion 21 and the opening 51 can be 2mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm or 100mm, etc.

[0079] In addition, the minimum distance between the electrode portion 22 and the opening 51 can be 2mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm or 100mm, etc.

[0080] In some embodiments of the present invention, a variable voltage can be applied between the electrode portion 22 and the first electrode 40, with the variable voltage ranging from -8000 V to -14000 V (high voltage DC voltage). By setting the variable voltage applied between the electrode portion 22 and the first electrode 40, the applicable range of the ion generating device 100 can be expanded.

[0081] It should be noted that the distance between the base portion 21 and the opening 51 may be -8000V, -9000V, -10000V, -11000V, -12000V, -13000V or -14000V, etc.

[0082] In some embodiments of the present invention, the thickness of the first electrode 40 is in the range of 0.1 mm to 10 mm. The thickness of the first electrode 40 is set so that the first electrode 40 can have sufficient strength.

[0083] It should be noted that the thickness of the first electrode 40 is 0.1 mm, 0.5 mm, 1 mm, 5 mm or 10 mm, etc. In addition, the first electrode 40 is a corrosion-resistant alloy.

[0084] In some embodiments of the present invention, an insulating layer is provided on the surface of the base portion 21 , and the thickness of the insulating layer is greater than or equal to 0.1 mm.

[0085] Specifically, by providing an insulating layer, the second electrode 20 can only form a non-equilibrium electric field through the electrode tip, so as to utilize the non-equilibrium electric field to ionize the air in the ionization space 50 to form a low-temperature plasma; the electric field can generate a corona at the electrode tip of the second electrode 20, and the corona is generated by the release of photons by electron transition after the air near the electrode tip is plasmatized, thereby greatly avoiding discharge and sparking to the outside world.

[0086] It should be noted that the thickness of the insulating layer can be 0.1 mm, 0.5 mm, 1 mm, 2 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm or 30 mm, etc.

[0087] In some embodiments of the present invention, multiple second electrodes 20 are provided. These multiple second electrodes 20 are spaced apart in parallel in the direction of the two openings 51, with the spacing between adjacent second electrodes 20 ranging from 0 mm to 1000 mm. By providing multiple second electrodes 20, the number of discharge locations can be increased, further improving the ability to achieve stable, continuous, self-sustaining discharge, forming a corona field, and achieving stable plasma generation. This effectively oxidizes organic matter in the air, destroys bacterial and viral DNA, and charges passing particulate matter and gas molecules in the air.

[0088] It should be pointed out that the spacing distance between two adjacent second electrodes 20 can be 0mm, 1mm, 2mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, 200mm, 500mm or 1000mm, etc.

[0090] It should be noted that the first electrode 40 and the opening 51 may be 2 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm or 30 mm, etc.

[0091] In some embodiments of the present invention, the insulating frame 10 is a bent plate-like member, and the bent plate-like member is U-shaped. The first electrode 40 closes the opening 51 of the U-shaped structure and encloses the ionization space 50 with the bent plate-like member. The wall thickness of the bent plate-like member (such as Figure 6 As shown, Figure 6 b7 is the wall thickness of the bent plate-like member and is within a range of 0.1 mm to 300 mm. The insulating frame 10 is configured to have good structural strength, thereby providing a stable supporting platform for the first electrode 40 and the second electrode 20, thereby effectively meeting the requirements of the ion generator 100.

The base portion 21 is disposed within the mounting groove 11. The cover 30 is disposed on the side of the base portion 21 facing the first electrode 40. The cover 30 is flush with the notch of the mounting groove 11. This arrangement can effectively improve the fixing strength of the second electrode 20.

[0093] In some embodiments of the present invention, the protrusion of the electrode portion 22 relative to the notch of the mounting groove 11 is in the range of 0 mm to 100 mm. This configuration enables the electrode portion 22 to effectively meet the discharge operation between the first electrodes 40.

[0094] It should be pointed out that the protruding size of the electrode portion 22 relative to the slot of the mounting slot 11 can be 1mm, 2mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm or 100mm, etc.
