[0038] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein like reference numerals identify similar elements or features throughout the figures. The embodiments described below are merely exemplary and are not intended to limit the application as there are many variations of the application which are possible.

[0039] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For purposes of explanation and ease of understanding, specific configurations and settings are set forth in the following description. Of course, these are merely examples and are not intended to limit the application. Also, the present application provides examples of various specific components and settings, but one of ordinary skill in the art will readily recognize that other components and settings can be used without departing from the application.

[0040] Hereinafter, referring to the drawings, the ion wind device 100 according to the first aspect embodiment of the present application is described.

[0041] As shown in Figure 1 and Figure 2 , the ion wind device 100 comprises a discharge electrode 1, a receiving electrode 2 and a first power supply 3, the discharge electrode 1 comprises a discharge tip, the receiving electrode 2 is arranged spaced apart from the discharge electrode 1, and the discharge tip is arranged towards the receiving electrode 2, that is, the receiving electrode 2 is arranged on the side of the discharge electrode 1 close to the discharge tip, and two output terminals of the first power supply 3 are connected to the discharge electrode 1 and the receiving electrode 2 respectively. Thus, under the action of the first power supply 3, the ion wind can be formed through the corona discharge of the discharge tip.

[0042] More specifically, when the first power supply 3 is working, the discharge electrode 1 generates charged particles through the corona discharge of the discharge tip, and the charged particles migrate from the discharge electrode 1 to the receiving electrode 2 under the action of the electric field between the discharge electrode 1 and the receiving electrode 2, thereby forming the ion wind, and further realizing the airflow driven by the wind wheel, saving the application of the wind wheel, and avoiding the problems of large space occupation, high working noise and high cost caused by the application of the wind wheel. In addition, the receiving electrode 2 can also simultaneously act as a dust collecting electrode to adsorb particulate matters in the air, so as to realize the function of purifying the air.

[0043] It can be understood that the first power supply 3 has a potential difference between the two output terminals connected to the receiving electrode 2 and the discharge electrode 1, for example, the first power supply 3 is connected to the discharge electrode 1 through the first output terminal, the first power supply 3 is connected to the receiving electrode 2 through the second output terminal, the potential of the first output terminal can be lower than the potential of the second output terminal, for example, the first output terminal is a negative electrode or a ground electrode, and the second output terminal is a positive electrode, of course, the present application is not limited thereto, for example, in other embodiments, the first output terminal and the second output terminal can also be connected in exchange, as long as the ion wind can be formed, which is not limited here.

[0044] In addition, it needs to be explained that in some embodiments, the first power supply 3 can be a direct current high voltage power supply, which adopts alternating voltage input, and after rectification and voltage boosting, outputs direct current high voltage. For example, the first power supply 3 can adopt a full-bridge phase-shifted driving circuit, and the voltage is adjusted through digital control, so as to realize the adjustment of the ion wind volume.

[0045] The applicant found that the above scheme would generate a large amount of ozone while improving the air volume. In order to solve the technical problem, the applicant creatively thought that the ozone regulation could be realized by introducing an additional electric field. The specific scheme is as follows.

[0046] As shown in Figure 1As shown, the ion wind device 100 further comprises accelerating electrodes 4 and second power supplies 5. The accelerating electrodes 4 are arranged between the discharge electrode 1 and the receiving electrode 2. The accelerating electrodes 4 are at least one, and the second power supplies 5 are also at least one. The second power supplies 5 are arranged one by one with the accelerating electrodes 4. Two output terminals of each second power supply 5 are connected with the corresponding accelerating electrode 4. Thus, under the action of the second power supply 5, an accelerating electric field is formed between the discharge electrode 1 and the receiving electrode 2.

[0047] That is, the number of the accelerating electrodes 4 is the same as that of the second power supplies 5. One accelerating electrode 4 is arranged with one second power supply 5. Each accelerating electrode 4 has two electrical connection terminals. Two output terminals of the second power supply 5 are connected with the two electrical connection terminals of the corresponding accelerating electrode 4, respectively. For example, the two output terminals of the second power supply 5 are a third output terminal and a fourth output terminal. The two electrical connection terminals of the accelerating electrode 4 are a first electrical connection terminal and a second electrical connection terminal. The third output terminal is connected with the first electrical connection terminal, and the fourth output terminal is connected with the second electrical connection terminal. The third output terminal and the fourth output terminal have a potential difference. For example, the third output terminal is a negative electrode or a ground electrode, and the fourth output terminal is a positive electrode.

[0048] Of course, the present application is not limited to this. For example, in other embodiments, the third output terminal and the fourth output terminal can be connected reversely, as long as the accelerating electric field can be formed. In addition, it should be noted that in some embodiments, the second power supply 5 can be a direct-current high-voltage power supply. The alternating voltage is input, and then the voltage is boosted after rectification and then doubled. Finally, the direct-current high-voltage is output. For example, the second power supply 5 can adopt a full-bridge phase-shifted driving circuit. The voltage is adjusted by digital control to achieve the adjustment of the accelerating electric field.

[0049] For example, in some optional embodiments, when the ion wind device 100 is applied, it can be determined according to the user's selection whether the user needs ozone. If the user needs ozone to purify the environment, the voltage of the first power supply 3 is increased, so that a large amount of ozone is generated while a high wind volume ion wind is formed. At the same time, the voltage of the second power supply 5 is reduced but higher than zero, so that the ion wind is slightly accelerated, thereby achieving the effect of purifying the air while the air flows. When it is determined that the user needs to enjoy the ion wind environment, the voltage of the first power supply 3 is reduced to reduce the generation of ozone, and the voltage of the second power supply 5 is increased to accelerate the ion wind, thereby obtaining a high-speed ion wind.

[0050] Of course, the present application is not limited to this, for example, in other embodiments of the present application, when it is determined that the user needs an ozone-purified environment, the voltage of the first power supply 3 can also not be adjusted, but the voltage of the first power supply 3 is maintained unchanged, and the like. For example, in other embodiments of the present application, when it is determined that the user needs an ozone-purified environment, the voltage of the second power supply 5 can also be reduced to zero, and the ion wind is not accelerated. For example, in other embodiments of the present application, when it is determined that the user needs a pure ion wind environment, the voltage of the second power supply 5 can also not be adjusted, but the voltage of the second power supply 5 is maintained unchanged, and the like, which will not be repeated here.

[0051] Therefore, according to the ion wind device 100 of the embodiment of the present application, by introducing the acceleration electrode 4 and cooperating with the arrangement of the separate second power supply 5, the migration of the ion wind can be accelerated, the formation of the ion wind is promoted, and the air volume is increased. And by controlling the voltage of the second power supply 5, the acceleration electric field can be controlled separately, and the strength of the acceleration electric field can be changed according to the demand. For example, when ozone is not needed, the voltage of the first power supply 3 can be appropriately reduced to reduce or avoid the generation of ozone, and the voltage of the second power supply 5 is increased, the acceleration electric field formed by the acceleration electrode 4 plays an effective acceleration role, the wind speed and the wind wheel of the ion wind are improved, and an ion wind environment with almost no ozone is formed. Therefore, by controlling the ion wind device 100, it can be selected whether to generate ion wind with almost no ozone or to generate ion wind containing ozone to purify the indoor environment.

[0052] In summary, according to the ion wind device 100 of the embodiment of the present application, the structure is simple, the parts are few, the cost is low, the quality is stable and reliable, it can be mass-produced, it can realize zero noise and vibration, it does not need the assistance of an additional air supply device (such as a wind wheel), it can form a comfortable ion wind, and it can freely select whether to generate ozone according to the user's demand, and meet the different actual needs of the user.

[0053] In some embodiments of the present application, such as Figure 1 and Figure 2As shown, the acceleration electrode 4 can include at least one conductive piece 41, and it is worth noting that when the conductive piece 41 is multiple, the multiple conductive pieces 41 can be connected in parallel and / or in series. Among them, the conductive piece 41 is long strip-shaped and the length of both ends is the input end and the output end respectively. That is, the current is input from one end of the length of the conductive piece 41, and then output from the other end of the length of the conductive piece 41, so that the acceleration electric field can be better formed by the conductive piece 41. For example, when the acceleration electrode 4 only includes one conductive piece 41, the two output ends of the second power supply 5 can be connected with the length of both ends of the conductive piece 41 respectively. When the acceleration electrode 4 includes multiple conductive pieces 41 connected in parallel, the two output ends of the second power supply 5 can be connected with the length of both ends of each conductive piece 41 respectively. When the acceleration electrode 4 includes multiple conductive pieces 41 connected in series, the length of both ends of the multiple conductive pieces 41 is connected in series, and the two output ends of the second power supply 5 can be connected with the length of both ends of the first conductive piece 41 and the length of both ends of the last conductive piece 41 respectively.

[0054] Therefore, the acceleration electric field can be better and easier to form by using the long strip-shaped conductive piece 41, and the flow resistance of the ion wind can be reduced, thereby effectively accelerating the effect. It is worth noting that "long strip-shaped" refers to a shape with a length much greater than a width, for example, the length is more than three times the width, and the width is understood in a broad sense, that is, the distance between the two most distant points on the maximum cross section of the conductive piece 41.

[0055] Optionally, each conductive piece 41 can be a conductive column or a conductive wire, so that the acceleration electrode 4 can include at least one conductive column and / or at least one conductive wire, thereby meeting different design requirements.

[0056] Among them, the conductive column can be rigid and not easy to bend and deform, thereby facilitating installation, positioning and setting. For example, it can be processed by using a conductive material such as metal, for example, copper, iron, alloy, tungsten and the like. In addition, the cross-sectional shape of the conductive column is not limited, for example, it can be circular, oval, rectangular, other regular polygon or special-shaped and the like. Optionally, the equivalent diameter D1 of the conductive column can be in the range of 1mm-20mm, for example, 1mm, 2mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm and the like, thereby ensuring that the conductive column has sufficient deformation resistance and good conductivity, improving the effectiveness of the acceleration electric field, and the cost is relatively low. Further, the equivalent diameter D1 of the conductive column can be in the range of 5mm-10mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm and the like. Therefore, the conductive column has sufficient deformation resistance and good conductivity, further improves the effectiveness of the acceleration electric field, and ensures that the cost is relatively low.

[0057] The specific mechanism and material of the conductive wire are not limited, for example, the conductive wire can only include a conductive wire core, or can include a conductive wire core and an insulating layer wrapped outside the conductive wire core, etc., and the material of the conductive wire core is not limited and can be selected according to actual requirements. It can be understood that the conductive wire has good conductivity, can achieve good conductivity, so as to better accelerate the electric field, and can save the space occupied, reduce the weight of the overall ion wind device 100, etc.

[0058] Optionally, the equivalent diameter D2 of the conductive wire core is 0.1mm-5mm, for example, 0.1mm, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4.0mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 4.0mm, etc., so as to better accelerate the electric field, and can save the space occupied, reduce the weight of the overall ion wind device 100, etc.

[0059] Further, the equivalent diameter D2 of the conductive wire core is 0.2mm-3mm, for example, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm, etc., so as to better accelerate the electric field, and can save the space occupied, reduce the weight of the overall ion wind device 100, etc. Further, the equivalent diameter D2 of the conductive wire core is 0.5mm-2mm, for example, 0.5mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm, etc., so as to further accelerate the electric field, and can save the space occupied, reduce the weight of the overall ion wind device 100, etc.

[0060] In some embodiments of the present application, as shown in Figure 2 The discharge electrode 1 includes at least one discharge body 11, each discharge body 11 includes a plurality of discharge tips arranged at intervals along the length direction of the discharge body 11, and the length extension direction of the conductive piece 41 is parallel to the length extension direction of the discharge body 11. Therefore, the ions migrated from the discharge electrode 1 can be effectively ensured to reach everywhere in the length direction of the conductive piece 41 synchronously, so as to improve the acceleration uniformity and better improve the wind speed and wind volume of the ion wind.

[0061] Further, as shown in FIG. 1, the length extension direction of the conductive member 41 can be parallel to the length extension direction of the discharge body 11. In this case, the conductive member 41 can be a plurality of members and arranged in a direction perpendicular to the length extension direction of the discharge body 11 (for example, the F2 direction shown in FIG. 1), and the discharge body 11 is arranged corresponding to the gap between the adjacent two conductive members 41. In this way, the acceleration effect of the electric field can be improved under the premise of reducing the wind resistance, so as to further improve the wind speed and the wind volume. Figure 2 Figure 2 Further, as shown in FIG. 1, the length extension direction of the conductive member 41 can be parallel to the length extension direction of the discharge body 11. In this case, the conductive member 41 can be a plurality of members and arranged in a direction perpendicular to the length extension direction of the discharge body 11 (for example, the F2 direction shown in FIG. 1), and the discharge body 11 is arranged corresponding to the gap between the adjacent two conductive members 41. In this way, the acceleration effect of the electric field can be improved under the premise of reducing the wind resistance, so as to further improve the wind speed and the wind volume.

[0062] In some embodiments of the present application, as shown in FIG. 1 and FIG. 2, the discharge electrode 1 comprises at least one discharge body 11, each discharge body 11 comprises a plurality of discharge tips arranged in a length direction of the discharge body 11, and the conductive member 41 is a plurality of members and arranged in a direction parallel to the length extension direction of the discharge body 11. In this way, the ions migrated from the discharge electrode 1 can be effectively ensured to reach the electric field formed by the plurality of conductive members 41 synchronously, so as to improve the acceleration uniformity and better improve the wind speed and the wind volume of the ion wind. Figure 4

[0063] It should be noted that the length extension direction of the conductive member 41 and the length extension direction of the discharge body 11 can be straight lines or curves, the straight line can be parallel to the plane, and the curve can be parallel to the curved surface, which is not limited here. In the following, the length extension direction of the conductive member 41 and the length extension direction of the discharge body 11 are straight lines as an example.

[0064] In some embodiments of the present application, as shown in FIG. 1 and FIG. 2, the discharge electrode 1 comprises at least one discharge body 11, each discharge body 11 comprises a plurality of discharge tips arranged in a length direction of the discharge body 11, and the conductive member 41 is a plurality of members and arranged in a direction parallel to the length extension direction of the discharge body 11. In this way, the ions migrated from the discharge electrode 1 can be effectively ensured to reach the electric field formed by the plurality of conductive members 41 synchronously, so as to improve the acceleration uniformity and better improve the wind speed and the wind volume of the ion wind. Figure 1 Figure 2

[0065] wherein the length center line refers to the center line extending in the length direction, for example, when the conductive member 41 is a conductive wire or a conductive column, the center axis of the conductive member 41 is the length center line, and the length center line of the discharge electrode 1 can be understood in the same way, for example, when the discharge electrode 1 is a substantially rectangular sheet, the axis extending in the length direction of the rectangular sheet and passing through the width center point is the length center line of the discharge electrode 1, and the width of the part on both sides of the length center line of the rectangular sheet is equal and is half of the width of the rectangular sheet.

[0066] ​​​​In some embodiments of the present invention, when projecting orthogonally onto the second plane, the length centerline of the conductive element 41 is parallel to the length centerline of the discharge electrode 1 (e.g., ...). Figure 1 and Figure 2 (as shown in the example) or vertical (e.g.) Figure 3 and Figure 4 (Example shown). This results in a better and more uniform accelerating electric field, leading to a better acceleration effect. Of course, the invention is not limited to this. For example, in other embodiments of the invention, when projecting onto the second plane, the center line of the conductive element 41 and the center line of the discharge electrode 1 may coincide or intersect at a non-zero angle, etc., which will not be elaborated here.

[0067] Furthermore, such as Figure 2 As shown, when projected onto the second plane, if the center line of the conductive element 41 is parallel to the center line of the discharge electrode 1, and the discharge electrode 1 also includes multiple discharge elements spaced apart, the conductive element 41 is staggered from the discharge elements. That is, a conductive element 41 is positioned in the gap between two adjacent discharge elements. This improves the acceleration effect and reduces obstruction and influence on ion migration, thereby increasing the wind speed and impeller of the ion wind. It should be noted that when the discharge electrode 1 includes multiple discharge elements spaced apart, the center lines of the lengths of the multiple discharge elements are coplanar with the second plane.

[0068] like Figure 1 and Figure 3 As shown, the discharge electrode 1 and the receiving electrode 2 are spaced apart along a first direction. Projected onto a plane parallel to the first direction, the ratio of the minimum distance L1 from the discharge tip to the accelerating electrode 4 (e.g., projected onto a third plane perpendicular to the second plane, the minimum distance from the discharge tip to the accelerating electrode 4 is L1) to the minimum distance L2 from the discharge tip to the receiving electrode (e.g., projected onto a third plane perpendicular to the second plane, the minimum distance from the discharge tip to the receiving electrode is L2) ranges from 1 / 2 to 1 / 6. That is, the range of L1 / L2 is 1 / 2 to 1 / 6. For example, L1:L2 can be 1:2, 1:3, 1:4, 1:5, 1:6, etc. This allows the accelerating electrode 4 to be located between the receiving electrode 2 and the discharging electrode 1, or to be positioned closer to the discharging electrode 1 than the receiving electrode 2. When the potential of the discharging electrode 1 is lower than that of the receiving electrode 2, an accelerating electric field can be supplemented at the weakest point in the electric field, increasing the wind speed and volume of the ion wind. This allows the ion wind device 100 to effectively regulate the airflow while ensuring sufficient ion wind generation.

[0069] Optionally, L1 can be in the range of 1mm-20mm, for example, 1mm, 2mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, etc., thereby achieving better acceleration effect and improving the wind speed and wind volume of the ion wind. Further, L1 can be in the range of 2mm-15mm, for example, 2mm, 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 15mm, etc., thereby achieving better acceleration effect and improving the wind speed and wind volume of the ion wind. Further, L1 can be in the range of 5mm-10mm, for example, 5mm, 6mm, 8mm, 10mm, etc., thereby achieving better acceleration effect and improving the wind speed and wind volume of the ion wind.

[0070] Optionally, L2 can be in the range of 10mm-50mm, for example, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, etc., thereby achieving better formation of the ion wind and ensuring the generation volume of the ion wind. Further, L2 can be in the range of 10mm-40mm, for example, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, etc., thereby achieving better formation of the ion wind and ensuring the generation volume of the ion wind. Further, L2 can be in the range of 15mm-30mm, for example, 15mm, 20mm, 25mm, 30mm, etc., thereby achieving better formation of the ion wind and ensuring the generation volume of the ion wind.

[0071] In some embodiments of the present application, as shown in Figure 2 and Figure 4 , the discharge electrode 1 and the receiving electrode 2 are spaced apart along a first direction, and the acceleration electrode 4 includes a plurality of conductive pieces 41 arranged along a second direction perpendicular to the first direction. In this way, the number of the acceleration electrode 4 can be increased as much as possible, thereby further improving the acceleration uniformity or acceleration effect of the acceleration electric field. For example, when the length center line of the conductive piece 41 is parallel to the length center line of the discharge electrode 1 in the orthographic projection onto the second plane, for example Figure 1 and Figure 2 , the second direction (e.g., the F2 direction shown in Figure 2 ) can be perpendicular to the length direction of the discharge electrode 1. For another example, when the length center line of the conductive piece 41 is perpendicular to the length center line of the discharge electrode 1 in the orthographic projection onto the second plane, for example Figure 3 and Figure 4 , the second direction (e.g., the F3 direction shown in Figure 4 ) can be the length direction of the discharge electrode 1.

[0072] In some embodiments of the present application, as shown inFigure 5 and Figure 6 As shown in FIG. 1, the discharge electrode 1 is spaced apart from the receiving electrode 2 along a first direction (e.g. the F1 direction as shown in FIG. 1), and the acceleration electrode 4 is multiple and distributed along the first direction in sequence. Figure 5 and Figure 6 As shown in FIG. 1, the discharge electrode 1 is spaced apart from the receiving electrode 2 along a first direction (e.g. the F1 direction as shown in FIG. 1), and the acceleration electrode 4 is multiple and distributed along the first direction in sequence.

[0073] In some embodiments of the present application, as shown in FIG. 1, the discharge electrode 1 comprises at least one discharge body 11, and each discharge body 11 comprises a plurality of discharge tips arranged in sequence along the length direction of the discharge body 11. Figure 1 For example, the discharge body 11 can be an electrode sheet, which comprises a body part and a sawtooth part connected to one side of the body part in the width direction, and the sawtooth part comprises a plurality of sawteeth arranged in the length direction of the body part, and each sawtooth comprises two sawtooth slant edges arranged in the length direction of the body part, and the two sawtooth slant edges are close to each other in the direction away from the body part to intersect to form a tooth tip of the sawtooth, and the tooth tip constitutes a discharge tip.

[0074] Therefore, compared with the structure of using a needle or a wire as a discharge tip, the discharge electrode 1 has certain advantages in positioning, installation and fixation. For example, for the wire structure, in order to position, a certain tension needs to be applied to both ends of the wire, and the wire is easy to break in the long-term high-voltage use process. For the needle structure, the needle needs to be inserted into the fixed conductive structure, which leads to complex process and great difficulty in processing, and is not conducive to large-scale production. In addition, in some embodiments, when the discharge electrode 1 comprises a plurality of electrode sheets, the plurality of electrode sheets can be arranged in sequence along the thickness direction (for example, as shown in FIG. 1), so as to improve the wind speed and the wind volume of the ion wind, which will not be described here. Figure 6

[0075] In the following, the ion wind device 100 according to some specific embodiments of the present application is described.

[0076] As shown in FIG. 1, the discharge electrode 1 is spaced apart from the receiving electrode 2 along a first direction (e.g. the F1 direction as shown in FIG. 1), and the acceleration electrode 4 is multiple and distributed along the first direction in sequence. Figure 1 and Figure 2 ​As shown, the ion wind device 100 includes a discharge electrode 1, a receiving electrode 2, an acceleration electrode 4, a first power supply 3 and a second power supply 5. The discharge electrode 1 includes an electrode sheet, the electrode sheet includes a body portion and a sawtooth portion, the sawtooth portion is connected to one side of the width of the body portion, the sawtooth portion includes a plurality of sawtooth arranged along the length direction of the body portion, each sawtooth includes two sawtooth oblique edges arranged along the length direction of the body portion, the two sawtooth oblique edges are close to each other along the direction away from the body portion to intersect to form a tooth tip of the sawtooth, and the tooth tip constitutes a discharge tip.

[0077] As shown in Figure 1 and Figure 2 The electrode sheet is multiple and is arranged in the thickness direction of each electrode sheet, and the length of each electrode sheet is fixed on the conductive metal fixing structure at both ends, forming the discharge electrode 1, and the first power supply 3 is connected to the metal fixing structure, so that all the discharge tips of all the electrode sheets of the discharge electrode 1 can perform corona discharge at the same time, and a large amount of ions can be generated.

[0078] The acceleration electrode 4 is placed between the discharge electrode 1 and the receiving electrode 2, in order to improve the uniformity of discharge, the nearest distance L1 of each tooth tip to the plane where the acceleration electrode 4 is located is the same, and the nearest distance L2 of each tooth tip to the plane where the receiving electrode 2 is located is the same. In order to ensure a large amount of ion wind and avoid mutual interference between electrodes, the spacing A between adjacent electrode sheets is in the range of 5mm-100mm, or 10mm-80mm, or 20mm-50mm, etc.

[0079] In order to ensure a large discharge efficiency, the included angle θ between the two sawtooth oblique edges of each sawtooth can be in the range of 5°-90°, and the spacing m of the adjacent two tooth tips in the length direction of the electrode sheet can be in the range of 1mm-10mm. Further, the included angle θ can be in the range of 10°-45°, and the spacing m can be in the range of 1mm-5mm. Further, the included angle θ can be in the range of 10°-20°, and the spacing m can be in the range of 1mm-3mm. Thus, the discharge efficiency can be better improved.

[0080] The sawtooth spacing of the discharge electrode 1 can also be formed by stacking a plurality of electrode sheets under the best processing conditions, that is, each electrode sheet includes at least two sub-sheets stacked in the thickness direction, each sub-sheet has a plurality of sawtooth, and the sawtooth of adjacent two sub-sheets are staggered, for example, fixed by screws, rivets or welding, easy to process. The sawtooth spacing can be adjusted, for example, the sawtooth spacing of the electrode sheet stacked by n sub-sheets is n equal division of the single spacing m, that is, the sawtooth spacing of the electrode sheet stacked by n sub-sheets becomes m / n, so that the value range of m / n is only 1mm-10mm, or 1mm-5mm, or 1mm-3mm, so that a smaller sawtooth spacing can be obtained under the premise of meeting the processing requirements.

[0081] The specific type of the discharge electrode 1 is not limited, for example, can be a hole plate electrode, a mesh electrode, a flat plate electrode, or a rod electrode, etc. Among them, for the mesh electrode, can be a metal mesh, the tangent lines of the points closest to the discharge tip and the mesh electrode plane on the circular arc are perpendicular to each other. In order to form a better potential difference, and better ion acceleration effect, the wire diameter of the mesh electrode can be 0.1mm-1mm, or 0.1mm-0.5mm, or 0.1mm-0.3mm, the mesh value can be 1 mesh / in 2 ~600 mesh / in 2 , or 10 mesh / in 2 ~80 mesh / in 2 , or 30 mesh / in 2 ~40 mesh / in 2 .

[0082] For the hole plate electrode, can be a metal hole plate, the tangent lines of the points closest to the discharge tip and the plane where the corresponding receiving electrode 2 is located on the circular arc are perpendicular to each other. The projection of the electrode sheet on the hole plate is located on the center line of the hole plate opening, and the distance E from the center line to the opening edge is in the range of 5mm-50mm, or 10mm-40mm, or 10mm-20mm. Control the gap between the openings to ensure that the hole plate opening rate is greater than 85%, and the thickness F of the metal hole plate can be less than 3mm.

[0083] For the flat plate electrode, can include a plurality of metal plates arranged in parallel, the electrode sheet is arranged in parallel with the metal plate, and the metal plate can be used as a dust collecting electrode to achieve the function of removing particulate matter. The projection of the plane where the discharge tip is located is located on the center line of the plane where the two metal plates are spaced apart, and the distance P from the center line to the opening edge can be in the range of 5mm-50mm, or 10mm-40mm, or 10mm-20mm, so that the distance K between the two metal plates can be in the range of 20mm-40mm. In order to ensure that the output ion wind has sufficient air volume and better particulate matter purification performance, the width of the metal plate can be in the range of 5mm-100mm, or 10mm-80mm, or 20mm-50mm.

[0084] Next, referring to the accompanying drawings, the air treatment device 1000 according to the second aspect of the present application is described.

[0085] As Figure 7As shown, the air treatment device 1000 can include: an ion wind device 100, which is the ion wind device 100 according to any one of the embodiments of the first aspect of the present application, and a treatment device 200, which is arranged upstream and / or downstream of the ion wind device 100 along the air outlet direction. In this way, the air treated by the treatment device 200 can be blown outwards. In summary, the air treatment device 1000 according to the embodiments of the present application, by arranging the ion wind device 100 of any one of the above embodiments, has the advantages of simple structure, fewer components, low cost, stable and reliable quality, large-scale production, zero noise, no vibration, no need for additional air supply device (such as a fan), comfortable ion wind, and free selection of ozone generation according to user needs, which meets different actual needs of users.

[0086] The air treatment device 1000 can include, but is not limited to, an air conditioner, for example, can also be an air purifier, an air humidifier, etc. In addition, the treatment device 200 is not limited in structure, for example, can include at least one of a heat exchange assembly, a humidifying assembly, and a sterilization assembly, the heat exchange assembly is used for heating or refrigerating air, the humidifying assembly is used for humidifying air, and the sterilization assembly is used for sterilizing and disinfecting air.

[0087] In some embodiments of the present application, as shown in Figure 7 The air treatment device 1000 is an air conditioner, and the air conditioner further includes a housing 300, the housing 300 is formed with an air inlet 301 and an air outlet 302, the ion wind device 100 and the treatment device 200 are arranged in the housing 300, and the treatment device 200 includes a heat exchanger capable of heat exchanging air in the housing 300, for example, refrigerating or heating air. Along the air outlet direction, the ion wind device 100 is arranged between the heat exchanger and the air inlet 301 (i.e., the ion wind device 100 is arranged upstream of the heat exchanger), or the ion wind device 100 is arranged between the heat exchanger and the air outlet 302 (i.e., the ion wind device 100 is arranged downstream of the heat exchanger).

[0088] In this way, when the ion wind device 100 is working, air outside the housing 300 can enter the housing 300 through the air inlet 301, the treatment device 200 can treat the air entering the housing 300, and the treated air can flow out of the housing 300 through the air outlet 302. It should be noted that the positions of the air inlet 301 and the air outlet 302 are not limited, and appropriate positions can be selected according to the specific type of the air conditioner, which will not be described here. Further, the housing 300 can have a mounting structure, and the ion wind device 100 can be mounted on the mounting structure, so that the ion wind device 100 can be stably arranged in the air conditioner, thereby stably generating ion wind and ensuring the stability of the air conditioner.

[0089] Next, a control method of the ion wind device 100 according to the third aspect embodiment of the present application is described.

[0090] The control method of the ion wind device 100 according to the embodiment of the present application is used for controlling the ion wind device 100 according to any one of the first aspect embodiments, the ion wind device 100 has a first mode and a second mode, the control method comprises: in the first mode, sending a voltage reduction control signal to the first power supply 3 to reduce the voltage of the first power supply 3 (i.e. the voltage input between the discharge electrode 1 and the receiving electrode 2), and sending a voltage increase control signal to the second power supply 5 to increase the voltage of the second power supply 5 (i.e. the voltage input to the acceleration electrode 4); in the second mode, sending a voltage increase control signal to the first power supply 3 to increase the voltage of the first power supply 3 (i.e. the voltage input between the discharge electrode 1 and the receiving electrode 2), and sending a voltage reduction control signal to the second power supply 5 to reduce the voltage of the second power supply 5 (i.e. the voltage input to the acceleration electrode 4).

[0091] Thus, in the first mode, since the voltage reduction control signal is sent to the first power supply 3 and the voltage increase control signal is sent to the second power supply 5, the generation of ozone can be inhibited as much as possible, and the wind speed of the ion wind can be increased as much as possible by the acceleration effect of the acceleration electrode 4, so as to increase the wind volume of the ion wind, thereby adapting to the pure enjoyment demand of the ion wind. In the second mode, since the voltage increase control signal is sent to the first power supply 3 and the voltage reduction control signal is sent to the second power supply 5, the ion wind and ozone with a larger wind volume can be generated, thereby meeting the demand of the user for purifying air by using ozone. And when the voltage of the second power supply 5 is not reduced to zero, a micro-acceleration effect can also be achieved, further increasing the wind speed and wind volume of the ion wind.

[0092] Optionally, in the first mode, the voltage of the first power supply 3 is controlled to be less than a first preset value, and the voltage of the second power supply 5 is controlled to be greater than or equal to a second preset value, the first preset value is greater than the second preset value, in the second mode, the voltage of the first power supply 3 is controlled to be greater than or equal to the first preset value, and the voltage of the second power supply 5 is controlled to be less than the second preset value. Thus, the control difficulty is lower, the control is more convenient, and the ozone air supply effect and the pure ion wind effect can be switched more obviously.

[0093] Optionally, in the first mode, the voltage of the second power supply 5 is also controlled to be less than or equal to a third preset value, that is, in the first mode, the voltage of the first power supply 3 is controlled to be less than the first preset value, and the voltage of the second power supply 5 is controlled to be greater than or equal to the second preset value and less than or equal to the third preset value, which can ensure that the acceleration effect is more reliable and effective, and the pure enjoyment effect of the ion wind is improved.

[0094] Optionally, in the second mode, the voltage of the first power supply 3 is also controlled to be less than or equal to a fourth preset value, and the fourth preset value is greater than the third preset value. That is, in the second mode, the voltage of the first power supply 3 is controlled to be greater than or equal to the first preset value and less than or equal to the fourth preset value, and the voltage of the second power supply 5 is controlled to be less than the second preset value. In this way, the amount of ion wind and the amount of ozone can be better controlled, thereby improving user comfort and the need for ozone to purify air.

[0095] Optionally, the first preset value is greater than the third preset value, and the third preset value is greater than the second preset value, thereby better achieving the generation and adjustment effect of ion wind. For example, in some embodiments, the fourth preset value is 30KV, the first preset value is 15KV, the third preset value is 10KV, and the second preset value is 5KV. Therefore, the control method can be that, in the first mode, the voltage of the first power supply 3 is controlled to be less than 15KV (for example, 0-15KV), and the voltage of the second power supply 5 is controlled to be greater than or equal to 5KV and less than or equal to 10KV (for example, 5kV-10KV), which can ensure that the acceleration effect is more reliable and effective, thereby improving the effect of pure ion wind. In the second mode, the voltage of the first power supply 3 is controlled to be greater than or equal to 15KV and less than or equal to 30KV (for example, 15kV-30KV), and the voltage of the second power supply 5 is controlled to be less than 5KV (for example, 0-5KV). In this way, the amount of ion wind and the amount of ozone can be better controlled, thereby improving user comfort and the need for ozone to purify air.

[0096] More specifically, when the ion wind device 100 is used in the air treatment equipment 1000, after the air treatment equipment 1000 is started, when the user selects the ozone-free mode, according to the preset wind speed, the voltage of the first power supply 3 (or the voltage between the input discharge electrode 1 and the receiving electrode 2) is reduced to 0-15KV, and the voltage of the second power supply 5 (or the voltage input to the acceleration electrode 4) is increased to 5kV-10KV. At this time, the ion wind is accelerated by the strong electric field of the acceleration electrode 4. Since the voltage of the discharge electrode 1 is very low at this time, the ozone concentration is only 0-20ppb, which is close to zero. When the user selects the ozone purification mode, according to the preset wind speed, the voltage of the first power supply 3 (or the voltage between the input discharge electrode 1 and the receiving electrode 2) is adjusted to 15kV-30KV, and the voltage of the second power supply 5 (or the voltage input to the acceleration electrode 4) is reduced to 0kV-5KV. At this time, the acceleration electrode 4 does not need too high voltage, and the voltage between the receiving electrode 2 and the discharge electrode 1 is very high, creating a high potential difference, and the ozone concentration can be increased to 20ppb-5ppm, which can achieve very good indoor purification effect, which is suitable for unmanned mode.

[0097] The first power supply 3 can be a direct current high voltage power supply, adopts alternating voltage input, the input voltage can be AC85V-AC265V, after rectification and voltage boosting, the voltage is raised to 4kV-6kV, and then through voltage multiplication, direct current high voltage is output, and the voltage range is 5kV-40kV. The second power supply 5 can be a direct current high voltage power supply, adopts alternating voltage input, the input voltage can be AC85V-AC265V, after rectification and voltage boosting, the voltage is raised to 4kV-6kV, and then through voltage multiplication, direct current high voltage is output, and the voltage range is 5kV-40kV. The first power supply 3 and the second power supply 5 can all adopt a full-bridge phase-shifted driving circuit, and the voltage is adjusted through digital control, so as to realize the adjustment of the ion wind volume.

[0098] Briefly, according to the air treatment equipment 1000 of the embodiment of the present application, in some embodiments, whether ozone is needed can be determined according to the wind speed and mode selected by the user, if ozone is needed to purify the environment, the voltage of the first power supply 3 can be adjusted to be high, and the voltage of the second power supply 5 can be adjusted to be low, so as to play a role of micro-acceleration. If the user needs to enjoy a negative ion environment, the voltage of the first power supply 3 can be adjusted to be low, the generation of ozone is inhibited, and the voltage of the second power supply 5 can be adjusted to be high, so that ion wind with high wind speed can still be obtained under the condition of low voltage.
