Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an ionization wind component and an air handling device having the same. Background Technology

[0002] Traditional air conditioners mostly use corona discharge to generate ion wind. The discharge electrode is made of needle or wire and the discharge electrode and the receiving electrode are arranged in a certain way. Under the action of high voltage power supply, ion wind is formed, realizing air delivery without impeller. However, corona discharge relies on the discharge of the tip, and the number of tips is usually limited, resulting in a limited number of ions generated, which leads to a small air volume. In order to increase the air volume, the voltage is generally increased. However, high voltage is prone to arcing, producing abnormal noise and affecting the safety of the ion wind component. Summary of the Invention

[0081] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0082] An ion wind assembly 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0083] like Figure 1-3 As shown, the ion wind assembly 100 according to a first aspect embodiment of the present invention includes: a discharge module 1, a receiving module 2, and a power supply module.

[0084] The discharge module 1 includes at least one discharge unit 10. For example, the discharge module 1 may have the following characteristics: Figure 2 The diagram shows a discharge unit 10, and the discharge module 1 can also be as follows: Figure 3 The diagram shows multiple discharge units 10 to increase the discharge range of the discharge module 1. The number of discharge units 10 is not limited here.

[0085] Specifically, the discharge unit 10 includes a dielectric layer 13, a first electrode layer 11, and a second electrode layer 12, with the first electrode layer 11 and the second electrode layer 12 respectively disposed on opposite sides of the dielectric layer 13 in the thickness direction. In other words, the discharge module 1 is composed of the first electrode layer 11, the second electrode layer 12, and the dielectric layer 13, with the dielectric layer 13 disposed between the first electrode layer 11 and the second electrode layer 12 to separate them.

[0086] Further, refer to Figures 2-5The first electrode layer 11 and the second electrode layer 12 are disposed opposite to each other. A hollow structure is formed on the first electrode layer 11, penetrating the first electrode layer 11 along the thickness direction. The receiving module 2 is disposed separately from the discharge module 1. The power supply module is electrically connected to the first electrode layer 11, the second electrode layer 12, and the receiving module 2, respectively, to drive the discharge module 1 to discharge through a dielectric barrier to generate charged particles, and to form an electric field between the discharge module 1 and the receiving module 2, causing the charged particles to migrate to the receiving module 2 to form an ion wind. That is to say, the receiving module 2 is suitable for receiving the charged particles generated by the discharge unit 10. Furthermore, since the receiving module 2 is disposed separately from the discharge module 1, the charged particles can drive the airflow during their migration from the discharge module 1 to the receiving module 2, thereby generating an ion wind.

[0087] Specifically, refer to Figure 6 and Figure 7 The discharge module 1 and the receiving module 2 can be spaced apart in the left-right direction, with the receiving module 2 located to the right of the discharge module 1. The first electrode layer 11, the dielectric layer 13, and the second electrode layer 12 are arranged in the front-back direction, with the first electrode layer 11 located on the front sidewall of the dielectric layer 13 and the second electrode layer 12 located on the rear sidewall of the dielectric layer 13. When the power module is connected to the first electrode layer 11, the second electrode layer 12, and the receiving module 2, since the dielectric layer 13 is located between the first electrode layer 11 and the second electrode layer 12, the high-voltage end of the power module can be connected to the first electrode layer 11 to discharge the first electrode layer 11 as a discharge electrode, thereby ionizing the air and generating charged particles. At the same time, an electric field from left to right is formed between the discharge module 1 and the receiving module 2. Therefore, the charged particles generated by the discharge of the discharge module 1 migrate towards the receiving module 2 under the action of the electric field, thereby driving the airflow during the movement of the charged particles, forming an ion wind flowing from left to right, thus achieving impeller-free air delivery.

[0088] The ionization of air via dielectric barrier discharge not only increases the number of discharge points, thereby improving the ionization efficiency and ion generation of the discharge unit 10, but also makes the discharge process of the discharge unit 10 more stable. Furthermore, it eliminates the possibility of sparking or other noises during the discharge process, thus enhancing the safety and stability of the air handling equipment 1000. Simultaneously, the flow of ionized air does not require a fan wheel, enabling the ionized air assembly 100 to achieve both silent discharge and silent airflow, thereby avoiding noise interference to users. When the ionized air assembly 100 is applied to the air handling equipment 1000, it contributes to improving the comfort level of the air handling equipment 1000.

[0089] Furthermore, by providing a hollow structure on the first electrode layer 11, an asymmetric electric field is formed on both sides of the dielectric layer 13 when the power module is energized with the first electrode layer 11 and the second electrode layer 12. This can significantly improve the ionization efficiency of the discharge unit 10, thereby increasing the amount of ions generated, increasing the ion airflow, and ultimately improving the airflow of the ion air assembly 100.

[0090] Furthermore, by using dielectric barrier discharge to generate ion wind, the charged particles generated by the discharge can also adsorb particulate matter such as dust in the air while generating airflow. That is, the receiving module 2 can also act as a dust collecting electrode to adsorb particulate matter that is combined with charged particles in the ion wind, thus achieving the function of purifying ion wind. This ensures that the air output from the ion wind component 100 is clean and hygienic, which is conducive to creating a healthy breathing environment for users.

[0091] According to the ion wind assembly 100 of the present invention, the discharge module 1 uses dielectric barrier discharge to generate ions. A hollow structure is formed on the first electrode layer 11 that penetrates the first electrode layer 11 along the thickness direction. When the power module is energized with the first electrode layer 11 and the second electrode layer 12, an asymmetric electric field is formed on both sides of the dielectric layer 13. This not only increases the discharge point of the discharge module 1, improves the ionization efficiency and the amount of ions generated, thereby increasing the air volume, but also makes the discharge more uniform and stable, without producing sparking noise. This enables silent discharge and silent air output, resulting in higher safety.

[0092] According to some embodiments of the present invention, the projection of the first electrode layer 11 onto the reference plane is a first projection, and the projection of the second electrode layer 12 onto the reference plane is a second projection, wherein the outer contour lines of the first projection and the second projection coincide. That is, the reference... Figure 8 In the thickness direction of the dielectric layer 13, the first electrode layer 11 and the second electrode layer 12 are symmetrically arranged with respect to the dielectric layer 13, and the areas of the first electrode layer 11 and the second electrode layer 12 are the same. Therefore, when the power module is connected to the first electrode layer 11 and the second electrode layer 12, the discharge unit 10 can discharge uniformly and generate charged particles, which helps to improve the discharge stability of the discharge unit 10.

[0093] According to some embodiments of the present invention, reference Figure 6 and Figure 7 The first electrode layer 11 has a mesh structure. Therefore, when the power module is connected to the first electrode layer 11 and the second electrode layer 12, the asymmetry of the electric field of the discharge unit 10 can be improved, thereby increasing the ionization efficiency and the amount of charged particles generated by the discharge unit 10, and thus increasing the ion flow rate.

[0094] Furthermore, the first electrode layer 11 includes multiple first electrode wires, which are interwoven to form a mesh. Specifically, when the power module is connected to the first electrode layer 11, the multiple first electrode wires are simultaneously connected to the power module. This can effectively increase the coverage area of ​​the first electrode layer 11, thereby increasing the discharge range of the discharge unit 10, which is beneficial for improving the ionization efficiency and ion generation of the discharge module 1, and for increasing the airflow of the ion wind assembly 100.

[0095] The first electrode wire can be made of a conductive material, which can include, but is not limited to, metals with excellent conductivity such as copper and aluminum. No specific restrictions are imposed here.

[0096] Optionally, the diameter of the first electrode wire is in the range of 0.1-1 mm, 0.1-0.5 mm, or 0.1-0.3 mm. That is, the diameter of the first electrode wire is controlled between 0.1 mm and 1 mm, or between 0.1 mm and 0.5 mm, or between 0.1 mm and 0.3 mm. In other words, the diameter of the first electrode wire is in the range of 0.1-1 mm, preferably 0.1-0.5 mm, and more preferably 0.1-0.3 mm. For example, the diameter of the first electrode wire can be 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, or 1 mm.

[0097] Therefore, the asymmetry of the electric field poles of the discharge unit 10 can be improved, thereby increasing the ionization efficiency and the amount of charged particles generated by the discharge unit 10, and thus increasing the airflow of the ion wind assembly 100. In addition, it can better avoid the increase in resistance of the first electrode wire to the ion wind caused by the wire diameter being too large, thereby reducing the flow resistance of the ion wind and thus reducing the energy consumption of the ion wind assembly 100.

[0098] In other examples, the first electrode wire includes a first electrode wire body and a conductive coating covering the outer surface of the first electrode wire body. That is, after the power module is connected to the first electrode layer 11, it can achieve ionization by discharging through the conductive coating. The conductive coating can be a coating made of materials such as carbon black, graphite, graphene, or fullerene, and there are no specific limitations here.

[0099] Furthermore, the thickness of the conductive coating ranges from 0.1-1 mm, or 0.1-0.5 mm, or 0.1-0.3 mm. That is, the thickness of the conductive coating is controlled between 0.1 mm and 1 mm, or between 0.1 mm and 0.5 mm, or between 0.1 mm and 0.3 mm. In other words, the thickness of the conductive coating ranges from 0.1-1 mm, preferably from 0.1-0.5 mm, and more preferably from 0.1-0.3 mm. For example, the thickness of the conductive coating can be 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, or 1 mm.

[0100] Therefore, the asymmetry of the electric field poles of the discharge unit 10 can be improved, thereby increasing the ionization efficiency and the amount of charged particles generated by the discharge unit 10, and thus increasing the airflow of the ion wind assembly 100. In addition, it can better avoid the increased resistance to the ion wind caused by the excessive diameter of the first electrode wire when the conductive coating is too thick, thereby reducing the flow resistance of the ion wind and thus reducing the energy consumption of the ion wind assembly 100.

[0101] Optionally, the mesh count ranges from 1 to 600 meshes / in², or 10 to 80 meshes / in², or 30 to 40 meshes / in². That is, the mesh count is controlled between 1 mesh / in² and 600 meshes / in², or between 10 meshes / in² and 80 meshes / in², or between 30 meshes / in² and 40 meshes / in². In other words, the mesh count ranges from 1 to 600 meshes / in². Preferably, the mesh count ranges from 10 meshes / in² to 80 meshes / in², and more preferably, the mesh count ranges from 30 meshes / in² to 40 meshes / in². For example, the number of meshes can be 1 mesh / in2, 10 mesh / in2, 20 mesh / in2, 30 mesh / in2, 40 mesh / in2, 60 mesh / in2, 80 mesh / in2, 100 mesh / in2, 300 mesh / in2, 500 mesh / in2, or 600 mesh / in2.

[0102] Therefore, the asymmetry of the electric field poles of the discharge unit 10 can be improved, thereby increasing the ionization efficiency and the amount of charged particles generated by the discharge unit 10, and thus increasing the airflow of the ion wind assembly 100. In addition, it can better avoid the increased resistance of the first electrode wire to the ion wind caused by the dense mesh and small aperture of the mesh when the mesh count is too large, thereby reducing the flow resistance of the ion wind and thus reducing the energy consumption of the ion wind assembly 100.

[0103] According to some embodiments of the present invention, reference Figure 8 and Figure 9The second electrode layer 12 is a solid structure without any perforations. Because the first electrode layer 11 has a perforated structure extending through its thickness, an asymmetric electric field is formed between the first electrode layer 11 and the second electrode layer 12 when the power module is connected to them. For example, when the first electrode layer 11 is connected to the high-voltage terminal of the power module and the second electrode layer 12 is grounded, the first electrode layer 11 becomes the discharge electrode of the discharge unit 10. This discharge through the first electrode layer 11 generates charged particles, which helps increase ionization efficiency and the amount of charged particles generated, thereby increasing the airflow of the ion wind assembly 100.

[0104] According to some embodiments of the present invention, the thickness of the dielectric layer 13 ranges from 0.1-10 mm or 0.1-3 mm. That is, the thickness of the dielectric layer 13 is controlled between 0.1 mm and 10 mm, or between 0.1 mm and 3 mm, meaning the thickness range of the dielectric layer 13 is 0.1-10 mm. Preferably, the thickness range of the dielectric layer 13 is 0.1-3 mm. For example, the thickness of the dielectric layer 13 can be 0.1 mm, 0.5 mm, 3 mm, 6 mm, or 10 mm.

[0105] This can be understood as follows: Since the dielectric layer 13 is located between the first electrode layer 11 and the second electrode layer 12 to separate them, and a relatively large voltage needs to be applied to the discharge unit 10 to ensure the ionization effect, if the thickness of the dielectric layer 13 is too small, it is very easy for the dielectric layer 13 to break down as the applied voltage increases, thus preventing the discharge unit 10 from properly ionizing and generating charged particles. Conversely, if the thickness of the dielectric layer 13 is too large, the power module needs to output a larger voltage to ensure that the voltage applied to the discharge unit 10 can meet the ionization requirements, increasing the energy consumption of the ion wind assembly 100.

[0106] Therefore, setting the thickness of the dielectric layer 13 to 0.1-10mm or 0.1-3mm can avoid the need to apply an excessively large voltage to the discharge unit 10 to achieve ionization when the dielectric layer 13 is too thick, and can also avoid the risk of the dielectric layer 13 being broken down before sufficient voltage is applied to the discharge unit 10 when the dielectric layer 13 is too thin, thus improving the stability of the ion wind component 100.

[0107] The dielectric layer 13 can be made of dielectric materials such as polytetrafluoroethylene, epoxy resin, quartz, glass or alumina, which have high resistivity and high dielectric constant. There are no specific restrictions on the material of the dielectric layer 13.

[0108] According to some embodiments of the present invention, the width of the discharge unit 10 is in the range of 10-100mm or 10-30mm in the direction of the electric field formed between the discharge module 1 and the receiving module 2. That is, the width of the discharge unit 10 is controlled between 10mm and 100mm or between 10mm and 30mm in the direction of the electric field formed between the discharge module 1 and the receiving module 2. In other words, the width of the discharge unit 10 is in the range of 10-100mm in the direction of the electric field formed between the discharge module 1 and the receiving module 2. Preferably, the width of the discharge unit 10 is in the range of 10-30mm. For example, the width of the discharge unit 10 can be 10mm, 30mm, 40mm, 50mm, 75mm, 90mm, or 100mm.

[0109] It is understandable that as the width of the discharge unit 10 increases, the coverage area of ​​the discharge unit 10 also increases, which is beneficial to improving the ionization efficiency of the discharge unit 10. However, as the width of the discharge unit 10 increases, the space occupied by the discharge unit 10 in the direction of the electric field formed between the discharge module 1 and the receiving module 2 also increases, making it difficult to maintain the appearance size of the ion wind assembly 100. When the ion wind assembly 100 is used in the air handling equipment 1000, it occupies a large installation space.

[0110] Secondly, as the width of the discharge unit 10 increases, the distance between the end of the discharge unit 10 away from the receiving module 2 and the receiving module 2 also increases in the electric field direction. This results in a longer movement path for the charged particles generated by ionization at the end of the discharge unit 10 away from the receiving module 2 towards the receiving module 2. Therefore, the power supply module needs to apply a voltage that can generate a larger electric field to the receiving module 2 and the discharge module 1 to ensure the smooth migration of charged particles, which also increases the energy consumption of the ion wind component 100.

[0111] Therefore, by setting the width range of the discharge unit 10 to 10-100mm or 10-30mm, the ionization effect of the discharge unit 10 is ensured while the installation space occupied by the discharge unit 10 in the width direction is minimized, which helps to reduce the overall size of the ion wind assembly 100. In addition, the movement distance of charged particles can be reduced, thereby reducing the load voltage of the power module and helping to reduce the energy consumption of the ion wind assembly 100.

[0112] According to some embodiments of the present invention, such as Figure 4 and Figure 8As shown, the discharge unit 10 includes a dielectric layer 13, a first electrode layer 11, and a second electrode layer 12. That is, the discharge unit 10 is constructed by stacking a first electrode layer 11, a dielectric layer 13, and an electrode layer along the thickness direction of the dielectric layer 13. In this case, the discharge unit 10 has a single-sided discharge structure. Therefore, by applying voltage to the first electrode layer 11 and the second electrode layer 12, such as connecting the first electrode layer 11 to a high-voltage terminal and grounding the second electrode layer 12, the first electrode layer 11 can act as a discharge electrode to ionize and generate charged particles. Then, under the action of the electric field, the charged particles move towards the receiving module 2, driving gas flow and thus forming an ion wind.

[0113] According to other embodiments of the present invention, such as Figure 5 and Figure 9 As shown, the discharge unit 10 includes two dielectric layers 13, two first electrode layers 11 and one second electrode layer 12. The second electrode layer 12 is sandwiched between the two dielectric layers 13, and the two first electrode layers 11 are respectively located on the side of the two dielectric layers 13 away from the second electrode layer 12.

[0114] Specifically, two dielectric layers 13 and two first electrode layers 11 are respectively disposed on opposite sides of the thickness direction of the second electrode layer 12. That is, both sides of the thickness direction of the second electrode layer 12 are provided with first electrode layers 11 and dielectric layers 13. Each dielectric layer 13 is disposed between the first electrode layer 11 and the second electrode layer 12 on the same side to separate the first electrode layer 11 and the second electrode layer 12 on the same side. The first electrode layer 11 has a hollow structure, so that when the power module is connected to the first electrode layer 11 and the second electrode layer 12, an asymmetrical electric field is formed to ionize the air and generate charged particles. For example, when the first electrode layer 11 is connected to the high-voltage end of the power module and the second electrode layer 12 is grounded, the first electrode layers 11 on both sides of the second electrode layer 12 are discharge electrodes. At this time, the discharge unit 10 has a double-sided discharge structure. Thus, the ionization effect and the amount of charged particles generated by the discharge unit 10 can be improved, which is beneficial to increasing the air volume of the ion wind assembly 100.

[0115] According to some embodiments of the present invention, the discharge module 1 includes a plurality of discharge units 10 arranged at intervals, and the plurality of discharge units 10 are arranged in parallel. Therefore, by providing a plurality of discharge units 10, the coverage area of ​​the discharge module 1 is increased, which is beneficial to improving the ionization efficiency and the amount of charged particles generated by the discharge module 1, thereby increasing the airflow of the ion wind assembly 100. In such cases... Figure 10 In the example shown, multiple discharge units 10 can be arranged at intervals along the thickness direction of the dielectric layer 13, thereby increasing the coverage area of ​​the discharge module 1 in the thickness direction of the dielectric layer 13.

[0116] Furthermore, by setting multiple discharge units 10, a gap is formed between any two adjacent discharge units 10. When the power module is connected to the first electrode layer 11 and the second electrode layer 12, the charged particles generated by the discharge of the discharge unit 10 can migrate towards the receiving module 2 under the action of the electric field through the gap between two adjacent discharge units 10. Since the multiple discharge units 10 are arranged in parallel, that is, the extension direction of the gap between any two adjacent discharge units 10 is parallel, the movement direction of the charged particles in the two adjacent gaps is parallel, that is, the flow direction of the ion wind is parallel. This can better avoid the mutual interference of the ion wind in the adjacent gaps, thereby reducing turbulence and improving the flow stability of the ion wind.

[0117] Optionally, the distance between each discharge unit 10 and the receiving module 2 is equal. That is, in the direction of the electric field, the charged particles generated by the ionization of each discharge unit 10 move an equal distance toward the receiving module 2 under the action of the electric field, thereby ensuring the stability of the airflow and avoiding turbulence. This allows the ion wind assembly 100 to output air evenly, which is beneficial to improving the comfort of the ion wind assembly 100.

[0118] Optionally, the number of discharge units 10 is at least three. For example, the number of discharge units 10 can be three, four, five, or six. The number of discharge units 10 can be flexibly set according to actual needs, and no specific limitation is made here. Further, the spacing between any two adjacent discharge units 10 is equal; and / or the value of the spacing s between two adjacent discharge units 10 is in the range of 10mm-100mm, or 10mm-80mm, or 10mm-20mm.

[0119] That is, the spacing between any two adjacent discharge units 10 can be equal, and the value of the spacing s between any two adjacent discharge units 10 can be in the range of 10mm-100mm, 10mm-80mm, or 10mm-20mm; or the spacing between any two adjacent discharge units 10 can be equal; or the value of the spacing s between any two adjacent discharge units 10 can be in the range of 10mm-100mm, 10mm-80mm, or 10mm-20mm.

[0120] The spacing between any two adjacent discharge units 10 is equal, so that the width of the ion wind flow between two adjacent discharge units 10 is the same in the arrangement direction of the multiple discharge units 10. This allows the ion wind assembly 100 to output air more evenly in the arrangement direction of the discharge units 10, which helps to improve the user comfort of the air handling equipment 1000.

[0121] Furthermore, as the distance between the two discharge units 10 increases, the friction between the charged particles and the adjacent discharge units 10 during their movement decreases, thus reducing the resistance of the ion wind. However, when the distance between two adjacent discharge units 10 is greater than the range of charged particle generation, there are no charged particles in the gap between the two adjacent discharge units 10, resulting in no ion wind in this part, which is not conducive to achieving uniform airflow from the ion wind assembly 100. When the distance between the two discharge units 10 is too small, since both the first electrode layer 11 and the second electrode layer 12 are connected to the power module, the first electrode layer 11 and the second electrode layer 12 after being powered on will have a certain interference to the adjacent discharge units 10, and the two discharge units 10 that are too close together will have a greater resistance to the ion wind.

[0122] Therefore, by setting the distance s between two adjacent discharge units 10 to 10mm-100mm, 10mm-80mm, or 10mm-20mm, interference between two adjacent discharge units 10 can be avoided, while the ion wind assembly 100 can output air evenly, which is beneficial to improving the safety and stability of the ion wind assembly 100, and can also reduce the resistance of the discharge unit 10 to the ion wind.

[0123] Specifically, the spacing between two adjacent discharge units 10 is controlled between 10mm and 100mm, or between 10mm and 80mm, or between 10mm and 20mm. That is, the spacing between two adjacent discharge units 10 is controlled between 10mm and 100mm. Preferably, the spacing s is in the range of 10mm-80mm, and more preferably in the range of 10mm-20mm. For example, the spacing s between two adjacent discharge units 10 can be 10mm, 20mm, 40mm, 60mm, 90mm, or 100mm. This effectively avoids interference between adjacent discharge units 10 while allowing the ion wind assembly 100 to output air evenly, which is beneficial for improving the safety and stability of the ion wind assembly 100, and can also effectively reduce the resistance of the discharge units 10 to the ion wind.

[0124] According to some embodiments of the present invention, the distance between the discharge unit 10 and the receiving module 2 is in the range of 3mm-50mm, or 5mm-30mm, or 10mm-20mm. That is, the distance between the discharge unit 1011 and the receiving electrode 2 is controlled between 3mm and 50mm, or 5mm and 30mm, or 10mm and 20mm. In other words, the value of L is in the range of 3mm-50mm, preferably in the range of 5mm-30mm, and more preferably in the range of 10mm-20mm. For example, the distance s3 between the discharge unit 10 and the receiving module 2 can be 3mm, 5mm, 8mm, 10mm, 15mm, 20mm, 25mm, 30mm, 40mm, or 50mm.

[0125] When the distance between the discharge unit 10 and the receiving module 2 is too small, such as less than 3mm, the distance between the first electrode layer and the second electrode layer 12 and the receiving module 2 is too small. During the operation of the ion wind assembly 100, the power module is connected to the first electrode layer 11, the second electrode layer 12 and the receiving module 2 at the same time. This makes it easy for arcing to occur between the first electrode layer 11 and the receiving module 2, which in turn causes the discharge module 1 to be unable to ionize normally.

[0126] Furthermore, when the distance between the discharge unit 10 and the receiving module 2 is too large, the charged particles travel an excessively long distance within the electric field between the discharge module 1 and the receiving module 2. Understandably, while maintaining a constant electric field, extending the travel path undoubtedly increases the kinetic energy loss of the charged particles, thus affecting the ion flow rate. Conversely, to ensure the charged particles travel a sufficient distance, it is necessary to increase the applied voltage to create a larger electric field between the discharge module 1 and the receiving module 2, thereby increasing the energy consumption of the ion wind assembly 100.

[0127] Specifically, refer to Figure 38 The ignition voltage in the figure is the voltage at which the ion wind component 100 first generates current. The ignition voltage is the voltage at which the ion wind component 100 will ignite when the voltage between the two poles is too high, affecting the normal operation of the ion wind component 100. The voltage at which the ignition phenomenon just occurs is the ignition voltage. The voltage window = ignition voltage - ignition voltage, which is the normal operating voltage of the ion wind component 100 and also the adjustable voltage range of the ion wind component 100. Among them, L is the factor that determines the voltage window. Adjusting the value of L can change the thickness of the ion wind component 100, i.e. the distance between the discharge unit 10 and the receiving module 2, and the voltage window, and will also affect the total air volume of the ion wind.

[0128] Furthermore, the spacing between the receiving modules, i.e., the width of the ion wind outlet, is also an important factor affecting the voltage window. When optimizing the ion wind assembly 100, the above parameters need to be adjusted simultaneously to obtain the best airflow effect. That is, after the electrode parameters (curvature, material, etc.) are determined, the parameter adjustment of the ion wind assembly 100 mainly involves adjusting the above parameters.

[0129] The choice of voltage range for the operating voltage of the ion wind module 100 depends on the actual needs. For example, in scenarios where the required ion air volume is small, a low-voltage (less than 6kV) ion wind module 100 can be selected. The advantages of this are higher safety, better electromagnetic compatibility, and fewer byproducts. However, the operating window is narrow, requiring a finely adjustable circuit. When strong airflow is required, a high-voltage (greater than 20kV) ion wind module 100 should be selected. In this state, the generated ion wind speed and volume are greater than at low voltage. However, safety regulations, electromagnetic compatibility, and byproduct issues must be considered, and a safe feedback signal acquisition circuit is also required.

[0130] Therefore, by setting the distance between the discharge unit 10 and the receiving module 2 to 3mm-50mm, 5mm-30mm, or 10mm-20mm, the energy consumption of the ion wind assembly 100 can be reduced effectively while avoiding mutual interference between the discharge unit 10 and the receiving module 2. Furthermore, the air output of the ion wind assembly 100 can be better guaranteed, facilitating the adjustment of the air volume of the ion wind assembly 100 and improving the operational stability of the ion wind assembly 100.

[0131] According to some embodiments of the present invention, the receiving module 2 is located on one side of the discharging module 1. For example... Figure 11 As shown, the charged particles generated by ionization move toward the direction of the receiving module under the action of the electric field, thereby realizing the directional air output of the ion wind component 100, that is, the air output direction is the direction of the discharge module 1 toward the receiving module 2.

[0132] According to other embodiments of the present invention, the receiving module 2 surrounds the outer periphery of the discharge module 1. That is, the receiving module 2 is formed in a ring shape and is sleeved on the outer periphery of the discharge module 1, with reference to... Figure 13 Under the influence of the electric field between the receiving module 2 and the discharge module 1, the charged particles move toward the direction closer to the receiving module 2. Since the receiving module 2 is located on the outer periphery of the discharge module 1, the charged particles generated by the ionization of the discharge module 1 move in the circumferential direction, that is, forming an ion wind flowing toward the outer periphery of the discharge module 1, so that the ion wind component 100 can emit air in the circumference of the receiving module 2.

[0133] In other words, the ion wind component 100 can achieve unidirectional airflow to one side or circumferential airflow. Therefore, by setting the receiving modules 2 at different positions, the airflow direction of the ion wind component 100 can be flexibly adjusted, so that the air handling equipment 1000 can flexibly adjust the layout of the receiving modules 2 according to the airflow requirements, thereby improving the applicability of the ion wind component 100.

[0134] According to some embodiments of the present invention, reference Figures 2-5 The power supply module includes: a high-voltage AC power supply unit 4, which includes a first high-voltage terminal and a first ground terminal. The first high-voltage terminal is electrically connected to the first electrode layer 11, and the first ground terminal is electrically connected to the second electrode layer 12; and a high-voltage DC power supply unit 3, which includes a second high-voltage terminal and a second ground terminal. The second high-voltage terminal is electrically connected to the receiving module 2, and the second ground terminal is electrically connected to the second electrode layer 12.

[0135] Thus, the first electrode layer 11 with the hollow structure becomes the discharge electrode, and charged particles are generated by the discharge through the first electrode layer 11. The high voltage DC power supply passes high voltage DC power to the receiving module 2 and the second electrode layer 12 to form an electric field between the discharge module 1 and the receiving module 2. Under the action of the electric field, the charged particles generated by the discharge of the first electrode layer 11 can flow along the electric field toward the receiving module 2, thereby generating an ion wind.

[0136] Wherein, when the discharge module 1 includes multiple discharge units 10, such as Figure 3 As shown, multiple discharge units 10 are arranged parallel to each other along the thickness direction of the dielectric layer 13. The first electrode layers 11 of the multiple discharge units 10 can be electrically connected through the first connector 14, and the second electrode layers 12 of the multiple discharge units 10 can be electrically connected through the second connector 15. The first high-voltage terminal is connected to the first connector 14, and the first ground terminal is connected to the second connector 15, thereby causing the multiple first electrode layers 11 to discharge and ionize to generate charged particles. This effectively eliminates the need for connecting the first high-voltage terminal to each of the multiple first electrode layers 11, and also eliminates the need for connecting the first ground terminal to each of the multiple second electrode layers 12, thus improving the connection efficiency between the high-voltage AC power supply unit 4 and the discharge module 1, and consequently improving the assembly efficiency of the ion wind assembly 100.

[0137] Furthermore, the second high-voltage terminal is connected to the receiving module 2, and the second ground terminal is connected to the second connector 15, so as to form an electric field between the discharge module 1 and the receiving module 2, so that the charged particles generated by ionization flow along the electric field toward the receiving module 2, thereby generating an ion wind.

[0138] Specifically, the power module can consist of one or more high-voltage AC power supply units 4 and high-voltage DC power supply units 3. From a practical point of view, both the high-voltage AC power supply unit 4 and the high-voltage DC power supply unit 3 can use AC voltage input, with an input voltage of AC85V-AC265V. The AC power supply is stepped up to 4kV-6kV by a transformer, and then multiplied to output high voltage, with a maximum voltage range of 10kV-30kV and a frequency of 50Hz-100kHz. At the same time, the high-voltage DC power supply unit 3 is rectified, stepped up by a transformer to 4kV-6kV, and then multiplied to output high-voltage DC, with a maximum voltage range of 20kV-40kV. Preferably, the power module adopts a full-bridge phase-shifting drive circuit and adjusts the voltage through digital control to regulate the air volume produced by the ion wind component 100.

[0139] According to some embodiments of the present invention, reference Figure 6 The receiving module 2 includes a mesh electrode 21, which comprises multiple second electrode wires 211. These wires interweave to form a ventilation mesh 212. This means that the ion wind generated by the migration of charged particles can be discharged through the ventilation mesh 212. Specifically, when the power module is connected to the receiving module 2, the second electrode wires 211 are energized, creating an electric field around them. This results in a relatively uniform electric field distribution, ensuring that the potential difference between multiple locations on the mesh electrode 21 and the corresponding locations on the discharge module 1 is the same. Consequently, the migration speed of charged particles is uniform, meaning the flow rate of the ion wind is the same at multiple locations, thus ensuring uniform airflow from the ion wind assembly 100.

[0140] In some embodiments, such as Figure 6 and Figure 10 As shown, the receiving module 2 includes a mesh electrode 21 and a first mounting bracket 213. Multiple second electrode wires 211 are interwoven to form the mesh electrode 21, and the first mounting bracket 213 is positioned circumferentially on the interwoven second electrode wires 211. Therefore, by connecting the first mounting bracket 213 between power modules, voltage can be applied to the multiple second electrode wires 211, reducing connection difficulty and significantly improving the structural strength of the mesh electrode 21.

[0141] According to some embodiments of the present invention, the receiving module 2 is located on one side of the discharge module 1, and the mesh electrode 21 is formed as a planar mesh. That is, the ion wind flow direction is towards the side where the discharge module 1 is located, facing the receiving module 2. This can effectively increase the coverage area of ​​the receiving module 2, resulting in a larger coverage area of ​​the electric field between the receiving module 2 and the discharge module 1, which is beneficial for increasing the migration of charged particles and thus increasing the airflow of the ion wind assembly 100. Furthermore, the discharge unit 10 is arranged perpendicularly to the receiving module 2. This allows an optimal potential difference to be formed between the receiving module 2 and the discharge module 1, thereby improving the acceleration effect of charged particles.

[0142] In some embodiments, reference Figures 10-12 The mesh electrode 21 is located on one side of the discharge module 1, which includes multiple discharge units 10, arranged parallel to each other along the thickness direction of the dielectric layer 13. The outer contour line of the projection of the discharge module 1 onto the reference surface parallel to the mesh electrode 21 is located inside the outer contour line of the projection of the mesh electrode 21 onto the reference surface. This ensures that the mesh electrode 21 can effectively receive the charged particles generated by the discharge module 1, thereby guaranteeing uniform airflow from the ion wind assembly 100. Furthermore, increasing the number of discharge units 10 improves the ionization efficiency and the amount of charged particles generated by the discharge module 1, thus increasing the airflow of the ion wind assembly 100.

[0143] According to some embodiments of the present invention, reference Figure 13 The receiving module 2 surrounds the outer periphery of the discharge module 1, and the mesh electrode 21 is formed as a cylindrical mesh. That is, the cylindrical mesh is fitted onto the outer periphery of the discharge module 1. Therefore, under the action of the electric field between the receiving module 2 and the discharge module 1, the charged particles move toward the direction closer to the cylindrical mesh. Since the cylindrical mesh surrounds the outer periphery of the discharge module 1, the charged particles generated by the ionization of the discharge module 1 move in the circumferential direction, that is, forming an ion wind flowing toward the outer periphery of the discharge module 1, so that the ion wind assembly 100 can emit air in the circumference of the receiving module 2.

[0144] Furthermore, the discharge module 1 includes a plurality of discharge units 10 spaced apart along the inner circumference of the cylindrical mesh. Thus, as the number of discharge units 10 increases, the ionization efficiency and the amount of charged particles generated by the discharge module 1 are improved, thereby increasing the airflow of the ion wind assembly 100. In addition, this ensures that charged particles are generated uniformly in the circumferential direction of the discharge module 1, thereby guaranteeing that ion wind is generated in the circumferential direction of the discharge module 1, and allowing the ion wind assembly 100 to output air uniformly in the circumferential direction.

[0145] Among them, reference Figure 8 and Figure 9 The discharge unit 10 can be Figure 8 The single-sided discharge structure shown can also be used for Figure 9 The double-sided discharge structure shown is beneficial for improving ionization efficiency and ion generation, and for increasing the air volume of the ion wind component 100. No specific limitations are imposed here.

[0146] In other words, the ion wind assembly 100 can achieve unidirectional airflow to one side or circumferential airflow. Therefore, by setting mesh electrodes 21 of different shapes and specifications, the airflow direction of the ion wind assembly 100 can be flexibly adjusted, so that the air handling equipment 1000 can flexibly adjust the layout of the receiving module 2 according to the airflow requirements, thereby improving the applicability of the ion wind assembly 100.

[0147] According to some embodiments of the present invention, the diameter of the second electrode wire 211 is in the range of 0.1-1 mm, or 0.1-0.5 mm, or 0.1-0.3 mm. That is, the diameter of the second electrode wire 211 is controlled between 0.1 mm and 1 mm, or between 0.1 mm and 0.5 mm, or between 0.1 mm and 0.3 mm. In other words, the diameter of the second electrode wire 211 is in the range of 0.1-1 mm, preferably between 0.1-0.5 mm, more preferably between 0.1-0.3 mm, for example, the diameter of the second electrode wire 211 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, or 1 mm. Therefore, it can avoid the problem that when the diameter of the electrode wire is too small, the electric field generated is too weak, making it difficult to effectively form an ion wind. At the same time, it can also avoid the problem that when the diameter of the second electrode wire 211 is too large, the resistance of the second electrode wire 211 to the ion wind will increase. This can effectively reduce the flow resistance of the ion wind and thus reduce the energy consumption of the ion wind assembly 100.

[0148] Furthermore, the mesh count of the ventilation mesh 212 ranges from 1-600 meshes / in², or 10-80 meshes / in², or 30-40 meshes / in². That is, the mesh count of the ventilation mesh 212 is controlled between 1 mesh / in² and 600 meshes / in², or between 10 meshes / in² and 80 meshes / in², or between 30 meshes / in² and 40 meshes / in². In other words, the mesh count of the ventilation mesh 212 ranges from 1-600 meshes / in², preferably, the number of ventilation meshes 212 ranges from 10 meshes / in² to 80 meshes / in², and more preferably, the number of ventilation meshes 212 ranges from 30 meshes / in² to 40 meshes / in². For example, the number of ventilation mesh openings 212 can be 1 mesh / in2, 10 mesh / in2, 20 mesh / in2, 30 mesh / in2, 40 mesh / in2, 60 mesh / in2, 80 mesh / in2, 100 mesh / in2, 300 mesh / in2, 500 mesh / in2 or 600 mesh / in2.

[0149] It is understandable that the mesh count of the ventilation mesh 212 is directly proportional to its density. A smaller mesh count results in a sparser mesh layout and a larger inner diameter, while a larger mesh count leads to a denser mesh layout and a smaller inner diameter. This effectively avoids uneven airflow caused by an uneven electric field when the mesh count of the ventilation mesh 212 is too small. Furthermore, it effectively avoids increased resistance to the ion wind from the receiving module 2 when the mesh count of the ventilation mesh 212 is too large, resulting in a denser mesh and smaller apertures. This reduces the flow resistance to the ion wind and consequently lowers the energy consumption of the ion wind assembly 100.

[0150] According to some embodiments of the present invention, reference Figures 22-25 The receiving module 2 includes an orifice plate 231 electrode 23, which includes an orifice plate 231 with an opening region 232. That is, the opening is formed on the orifice plate 231, so that charged particles moving towards the receiving module 2 can flow out through the opening on the orifice plate 231 under the action of the electric field between the receiving module 2 and the discharge module 1, thereby ensuring the smooth flow of the ion wind.

[0151] Optionally, the receiving module 2 is located on one side of the discharge module 1, and the perforated plate 231 is a planar plate. That is, the ion airflow direction is towards the side where the discharge module 1 is located, facing the receiving module 2. This effectively increases the coverage area of ​​the receiving module 2, resulting in a larger electric field coverage area between the receiving module 2 and the discharge module 1, which is beneficial for increasing the migration of charged particles and thus increasing the airflow of the ion air assembly 100. Furthermore, the perforated plate 231 is arranged perpendicularly to the discharge unit 10. This allows for the formation of an optimal potential difference between the receiving module 2 and the discharge module 1, thereby enhancing the acceleration effect of charged particles.

[0152] In some examples, reference Figures 26-28 The orifice plate 231 is located on one side of the discharge module 1. The discharge module 1 may include multiple discharge units 10, which are spaced apart and arranged in parallel along the thickness direction of the dielectric layer 13. The orifice plate 231 has multiple opening areas 232, which are spaced apart along the thickness direction of the dielectric layer 13, and the multiple discharge units 10 correspond one-to-one with the multiple openings. Thus, the multiple discharge units 10 increase the ionization efficiency of the discharge module 1 on the air, thereby increasing the amount of charged particles generated per unit time to ensure that the ion wind volume is large enough; while the multiple opening areas 232 ensure that the ion wind generated by each discharge unit 10 can be discharged from the corresponding opening area 232, thereby making the air outlet of the ion wind assembly 100 more uniform and the air outlet effect better.

[0153] Optionally, the receiving module 2 surrounds the outer periphery of the discharge module 1, and the perforated plate 231 is a cylindrical plate. That is, the cylindrical plate is fitted onto the outer periphery of the discharge module 1. Under the action of the electric field between the receiving module 2 and the discharge module 1, charged particles move towards the cylindrical plate. Since the cylindrical plate surrounds the outer periphery of the discharge module 1, the charged particles generated by the ionization of the discharge module 1 move in the circumferential direction, that is, forming an ion wind flowing towards the outer periphery of the discharge module 1, so that the ion wind assembly 100 can emit air in the circumference of the receiving module 2.

[0154] In some embodiments, reference Figure 29 The column panel is fitted onto the outer periphery of the discharge module 1, and the discharge module 1 includes a plurality of discharge units 10 arranged parallel to each other along the axial direction of the column panel. Therefore, as the number of discharge units 10 increases, the ionization efficiency and the amount of charged particles generated by the discharge module 1 are improved, thereby increasing the airflow of the ion wind assembly 100. Furthermore, the discharge units 10 are formed in a ring shape, so that ion wind can be generated uniformly in the circumferential direction of the discharge units 10, and the plurality of discharge units 10 arranged parallel to each other along the axial direction can uniformly generate charged particles in the axial direction of the receiving module 2, making the airflow from the ion wind assembly 100 more uniform in the circumferential direction.

[0155] Among them, reference Figure 24 and Figure 25 The discharge unit 10 can be Figure 24 The single-sided discharge structure shown can also be used for Figure 25 The double-sided discharge structure shown is beneficial for improving ionization efficiency and ion generation, and for increasing the air volume of the ion wind component 100. No specific limitations are imposed here.

[0156] In other words, the ion wind assembly 100 can achieve unidirectional airflow and circumferential airflow. By setting different shaped perforated plates 231 and electrodes 23, the airflow direction of the ion wind assembly 100 can be flexibly adjusted, so that the air handling equipment 1000 can flexibly adjust the layout of the receiving module 2 according to the airflow requirements, thereby improving the applicability of the ion wind assembly 100.

[0157] In some embodiments, the aperture ratio of the perforated plate 231 is greater than 85%. Here, the aperture ratio refers to the proportion of the area of ​​the perforated area 232 to the area corresponding to the outer contour of the perforated plate 231. For example, the aperture ratio of the perforated plate 231 can be 85%, 88%, 90%, or 95%. This is beneficial for reducing the wind resistance of the perforated area 232 and for reducing the weight of the receiving module 2.

[0158] Optionally, the thickness k of the perforated plate 231 is less than 3 mm. For example, the thickness k of the perforated plate 231 can be 1.5 mm, 2 mm or 2.5 mm. This not only helps to reduce the weight of the perforated plate 231 and the weight of the receiving module 2, but also ensures that the strength of the electric field generated by the perforated plate 231 is sufficient to drive the migration of charged particles to form an ion wind.

[0159] In some embodiments, the extension direction of the aperture region 232 is parallel to the extension direction of the discharge unit 10. One aperture region 232 corresponds to one discharge unit 10. The length center line of the discharge unit 10 is opposite to that of the corresponding aperture region 232. That is, for example, when the discharge unit 10 extends in the left-right direction, the depth direction of the aperture region 232 is parallel to the extension direction of the discharge unit 10. In this way, the charged particles generated by the discharge unit 10 are subjected to the electric field generated by the electrode 23 of the perforated plate 231 for a longer time after passing through the aperture region 232, which is beneficial to further increase the wind speed of the ion wind.

[0160] Furthermore, the value of m between the center line of the opening area 232 and the two sides of the opening area 232 along the width direction is 5mm-50mm, or 10mm-40mm, or 10mm-20mm. That is, the value of m between the center line of the opening area 232 and the two sides of the opening area 232 along the width direction is controlled between 5mm and 50mm, or between 10mm and 40mm, or between 10mm and 20mm. In other words, the value of m between the center line of the opening area 232 and the two sides of the opening area 232 along the width direction is 5mm-50mm. Preferably, the value of m between the center line of the opening area 232 and the two sides of the opening area 232 along the width direction is 10mm-40mm. More preferably, the value of m between the center line of the opening area 232 and the two sides of the opening area 232 along the width direction is 10mm-20mm. For example, the distance m between the center line of the opening area 232 and the two sides of the opening area 232 along the width direction can be 5mm, 10mm, 15mm, 20mm, 30mm, 35mm, 40mm, 45mm or 50mm.

[0161] Therefore, it can avoid the situation where the distance m from the center line of the opening area 232 to the two sides of the opening area 232 along the width direction is too small, for example, less than 5 mm, which would lead to increased wind resistance and thus increased airflow loss of ion wind. It can also avoid the situation where the distance m from the center line of the opening area 232 to the two sides of the opening area 232 along the width direction is too large, for example, greater than 50 mm, which would lead to a small electric field strength at the center of the opening plate 231 in the opening area 232, and thus reduce the acceleration effect and efficiency of the electrode 23 of the opening plate 231 on charged particles.

[0162] According to some embodiments of the present invention, reference Figures 14-17 The receiving module 2 includes rod electrodes 22, which comprises multiple spaced and parallel electrode rods 221, with a first ventilation gap 222 formed between adjacent electrode rods 221. This allows charged particles moving towards the receiving module 2 to pass through the first ventilation gap 222 under the influence of the electric field between the receiving module 2 and the discharge module 1, ensuring smooth flow of the ion wind and reducing the wind resistance of the receiving module 2 to the ion wind.

[0163] In some embodiments, the distance d between two adjacent electrode rods 221 is in the range of 1mm-50mm, 1mm-30mm, or 5mm-20mm, that is, the distance d between two adjacent electrode rods 221 is controlled within the range of 1mm to 50mm, 1mm to 30mm, or 5mm to 20mm. In other words, the distance d between two adjacent electrode rods 221 is in the range of 1mm-50mm. Preferably, the distance d between two adjacent electrode rods 221 is in the range of 1mm-30mm. More preferably, the distance d between two adjacent electrode rods 221 is in the range of 5mm-20mm. For example, the distance d between two adjacent electrode rods 221 can be 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 40mm, or 50mm.

[0164] Therefore, it can avoid the situation where the distance d between two adjacent electrode rods 221 is too large, resulting in an electric field at the first ventilation gap 222 being too weak, making it difficult to drive charged particles to migrate and form ion wind or to have an insignificant acceleration effect on charged particles. It can also avoid the situation where the distance d between two adjacent electrode rods 221 is too small, resulting in increased wind resistance at the first ventilation gap 222 and increased airflow loss of ion wind.

[0165] Optionally, the cross-section of the electrode rod 221 can be circular, and the diameter D of the electrode rod 221 can be in the range of 1mm-20mm or 1mm-10mm, that is, the diameter D of the electrode rod 221 is controlled between 1mm and 20mm or between 1mm and 10mm. In other words, the electrode rod 221 is formed as a cylinder, and the diameter D of the electrode rod 221 is in the range of 1mm-20mm. Preferably, the diameter D of the electrode rod 221 is in the range of 1mm-10mm. For example, the diameter D of the electrode rod 221 can be 1mm, 5mm, 8mm, 10mm, 15mm or 20mm.

[0166] Therefore, it can avoid the situation where the diameter D of the electrode rod 221 is too large, for example, greater than 20 mm, which would result in a large wind resistance of the electrode rod 221 to the ion wind, leading to increased air volume loss, reduced air output effect, and increased overall weight of the ion wind assembly 100. It can also avoid the situation where the diameter D of the electrode rod 221 is too small, for example, less than 1 mm, which would reduce the field strength of the electric field generated by the electrode rod 221 and reduce the driving and acceleration effect on charged particles.

[0167] Optionally, refer to Figures 18-20 The receiving module 2 is located on one side of the discharge module 1, which includes multiple discharge units 10 arranged in parallel. These multiple discharge units 10 increase the ionization efficiency of the air by the discharge module 1, thereby increasing the amount of charged particles generated per unit time and ensuring a sufficiently large ion wind. Furthermore, the plane containing the center lines of the multiple electrode rods 221 is perpendicular to the multiple discharge units 10. This allows for the formation of an optimal potential difference, thereby enhancing the acceleration effect of charged particles.

[0168] In some examples, such as Figure 18 As shown, multiple discharge units 10 can be spaced apart and arranged parallel to each other along the thickness direction of the dielectric layer 13. The first ventilation gap 222 formed between two adjacent electrode rods 221 corresponds one-to-one with the multiple discharge units 10, and the length centerline of the discharge unit 10 is opposite to that of the corresponding first ventilation gap 222. Therefore, the ion wind generated by each discharge unit 10 can flow out from the corresponding first ventilation gap 222. Simultaneously, placing the discharge unit 10 on the centerline of the length of the corresponding first ventilation gap 222 makes the airflow more uniform throughout the first ventilation gap 222, thus making the airflow from the ion wind assembly 100 more balanced. Furthermore, the multiple first ventilation gaps 222 corresponding one-to-one with the multiple discharge units 10 ensure that the ion wind generated by each discharge unit 10 can be discharged from the corresponding first ventilation gap 222, thus making the airflow from the ion wind assembly 100 more uniform and improving the airflow effect.

[0169] In some embodiments, the electrode rod 221 can be arranged parallel to the discharge unit 10, or it can be arranged perpendicular to the discharge unit 10. For example, the length direction of the discharge unit 10 is parallel to the vertical direction, while the electrode rod 221 is arranged vertically. In this case, the electrode rod 221 is arranged parallel to the discharge unit 10, resulting in less wind resistance in the vertical direction when the ion wind passes through the ventilation gap. Alternatively, the electrode rod 221 can be arranged horizontally. In this case, the electrode rod 221 is arranged perpendicular to the discharge unit 10, resulting in less wind resistance in the circumferential direction when the ion wind passes through the ventilation gap. Therefore, the ion wind assembly 100 has diverse structural forms to meet the needs of different users.

[0170] Optionally, refer to Figure 21 The receiving module 2 surrounds the outer periphery of the discharge module 1. The discharge module 1 includes multiple discharge units 10 spaced apart circumferentially, and multiple electrode rods 221 spaced apart circumferentially. Therefore, increasing the number of discharge units 10 improves the ionization efficiency and the amount of charged particles generated by the discharge module 1, thereby increasing the airflow of the ion wind assembly 100. Under the influence of the electric field between the receiving module 2 and the discharge module 1, the charged particles move towards the electrode rods 221. Since the multiple electrode rods 221 surround the outer periphery of the discharge module 1, the charged particles generated by the ionization of the discharge module 1 move circumferentially, forming an ion wind flowing towards the outer periphery of the discharge module 1. This allows the ion wind assembly 100 to output airflow circumferentially around the receiving module 2.

[0171] Among them, reference 16 and Figure 17 The discharge unit 10 can be Figure 16 The single-sided discharge structure shown can also be used for Figure 17 The double-sided discharge structure shown is beneficial for improving ionization efficiency and ion generation, and for increasing the air volume of the ion wind component 100. No specific limitations are imposed here.

[0172] Furthermore, the cylindrical surfaces containing the center lines of the multiple electrode rods 221 are coaxial with the cylindrical surfaces containing the center lines of the multiple discharge units 10. That is, on a reference plane perpendicular to the axis of the discharge unit 10, the outer contours of the projections of the cylindrical surfaces containing the center lines of the multiple electrode plates 241 onto the reference plane are concentric circles with the outer contours of the projections of the discharge unit 10 onto the reference plane. This ensures that the distance from any point on the outer periphery of the discharge unit 10 to the corresponding first ventilation gap 222 is the same, resulting in more uniform airflow from the ionization wind assembly 100 in the circumferential direction.

[0173] In some embodiments, reference Figure 18 The receiving module 2 includes rod electrodes 22 and a second mounting bracket 223. The rod electrodes 22 include multiple electrode rods 221, which are arranged in parallel at intervals. The two ends of the multiple electrode rods 221 are connected to the second mounting bracket 223 at their respective extension directions. Therefore, voltage can be applied to the multiple electrode rods 221 by directly connecting the power module to the first mounting bracket 213, reducing connection difficulty and significantly improving the connection stability between the multiple electrode rods 221, as well as the structural strength of the receiving module 2.

[0174] According to some embodiments of the present invention, reference Figures 30-33The receiving module 2 includes a flat electrode 24, which comprises multiple electrode plates 241 arranged at intervals and in parallel, with a second ventilation gap 242 formed between adjacent electrode plates 241. Thus, under the influence of the electric field between the receiving module 2 and the discharge module 1, charged particles moving towards the receiving module 2 can flow out through the second ventilation gap 242 between adjacent electrode plates 241, ensuring smooth flow of the ion wind and reducing the wind resistance of the receiving module 2 to the ion wind. This also helps maintain a consistent airflow direction within the ventilation gap, thus avoiding turbulence. Furthermore, the flat electrode 24 has a certain length in the direction of ion wind flow, increasing the contact time between charged particles and the flat electrode motor. This facilitates the flat electrode motor's adsorption of dirt and other particles adsorbed in the ion wind, thereby improving the purification effect of the flat electrode motor.

[0175] In some embodiments, reference Figures 34-36 The flat electrode 24 is located on one side of the discharge module 1. The discharge module 1 includes multiple discharge units 10 arranged in parallel. The multiple discharge units 10 can be spaced apart and arranged in parallel along the thickness direction of the dielectric layer 13. The second ventilation gap 242 formed between two adjacent electrode plates 241 corresponds one-to-one with the multiple discharge units 10. Thus, the multiple discharge units 10 increase the ionization efficiency of the discharge module 1 for air, thereby increasing the amount of charged particles generated per unit time to ensure that the ion wind volume is large enough. The multiple ventilation gaps corresponding one-to-one with the multiple discharge units 10 can ensure that the ion wind generated by each discharge unit 10 can be discharged from the corresponding ventilation gap, thereby making the air outlet of the ion wind assembly 100 more uniform and the air outlet effect better.

[0176] Optionally, refer to Figure 37 The discharge unit 10 is formed as a flat plate and is annular. The discharge module 1 includes multiple discharge units 10 spaced apart along the axial direction. The electrode plate 241 is formed as an annular planar plate and surrounds the outer periphery of the discharge module 1. The flat plate electrode 24 includes multiple electrode plates 241 spaced apart along the axial direction. Thus, as the number of discharge units 10 increases, the ionization efficiency and the amount of charged particles generated by the discharge module 1 are improved, thereby increasing the airflow of the ion wind assembly 100. In addition, the discharge unit 10 is formed as an annular plate, so that ion wind can be generated evenly in the circumferential direction of the discharge unit 10. Moreover, the multiple discharge units 10 spaced parallel to each other along the axial direction can uniformly generate charged particles in the axial direction of the receiving module 2, making the airflow of the ion wind assembly 100 more uniform in the circumferential direction.

[0177] Among them, reference 32 and Figure 33 The discharge unit 10 can be Figure 32 The single-sided discharge structure shown can also be used for Figure 33The double-sided discharge structure shown is beneficial for improving ionization efficiency and ion generation, and for increasing the air volume of the ion wind component 100. No specific limitations are imposed here.

[0178] Furthermore, the receiving module 2 and the discharge module 1 are coaxially arranged. That is, on a reference plane perpendicular to the axis of the discharge unit 10, the outer contour of the projection of the receiving module 2 onto the reference plane and the outer contour of the projection of the discharge unit 10 onto the reference plane are concentric circles. This ensures that the distance from any point on the outer periphery of the discharge unit 10 to the corresponding second ventilation gap 242 is the same, making the airflow from the ion wind assembly 100 more uniform in the circumferential direction.

[0179] In some embodiments, the receiving module 2 includes a flat plate electrode 24 and a third mounting bracket 243. The flat plate electrode 24 includes multiple electrode plates 241, which are arranged in parallel and spaced apart. The two ends of the multiple electrode plates 241 extending in the direction of extension are respectively connected to the third mounting bracket 243. Therefore, voltage can be applied to the multiple electrode plates 241 by directly connecting the power module to the third mounting bracket 243, reducing the connection difficulty and improving the connection stability between the multiple electrode plates 241, as well as the structural strength of the receiving module 2.

[0180] In some embodiments, the distance n from the center line of the second ventilation gap 242 to the corresponding electrode plate 241 ranges from 5mm to 50mm, or 10mm to 40mm, or 10mm to 20mm. That is, the distance n from the center line of the second ventilation gap 242 to the corresponding electrode plate 241 is controlled between 5mm and 50mm, or between 10mm and 40mm, or between 10mm and 20mm. In other words, the distance n from the center line of the second ventilation gap 242 to the corresponding electrode plate 241 ranges from 5mm to 50mm. Preferably, the distance n from the center line of the second ventilation gap 242 to the corresponding electrode plate 241 ranges from 10mm to 40mm. More preferably, the distance n from the center line of the second ventilation gap 242 to the corresponding electrode plate 241 ranges from 10mm to 20mm. For example, n can be 5mm, 10mm, 15mm, 20mm, 30mm, or 50mm.

[0181] Therefore, the width of the second ventilation gap 242 can be set more effectively, which can avoid uneven airflow in the windless area of ​​the second ventilation gap 242 due to the second ventilation gap 242 being too large, and can also avoid excessive resistance to the flow of ion wind due to the second ventilation gap 242 being too small, thereby reducing the flow loss of ion wind and improving the air volume of the ion wind component 100.

[0182] According to some embodiments of the present invention, the electrode plate 241 and the discharge unit 10 are arranged in parallel. That is, the flow direction of the ion wind is parallel to the electrode plate 241, thereby reducing the flow resistance of the electrode plate 241 to the ion wind, which is beneficial to increasing the air volume of the ion wind assembly 100 and reducing the energy consumption of the ion wind assembly 100.

[0183] Furthermore, the width P of the electrode plate 241 in the direction of the electric field ranges from 5mm to 100mm, or 10mm to 80mm, or 20mm to 50mm. That is, the width P of the electrode plate 241 in the direction of the electric field is controlled between 5mm and 100mm, or between 10mm and 80mm, or between 20mm and 50mm. In other words, the width P of the electrode plate 241 in the direction of the electric field ranges from 5mm to 100mm. Preferably, the width P of the electrode plate 241 in the direction of the electric field ranges from 10mm to 80mm. More preferably, the width P of the electrode plate 241 in the direction of the electric field ranges from 20mm to 50mm. For example, the width P of the electrode plate 241 in the direction of the electric field can be 5mm, 20mm, 30mm, 50mm, 80mm, or 100mm.

[0184] Therefore, it can better avoid the problem that the electrode plate 241 is too narrow in the electric field direction, which would prevent the electrode plate 241 from making sufficient contact with the ion wind and thus affecting the purification capacity. In addition, it can also better avoid the problem that the electrode plate 241 is too wide in the electric field direction, which would increase the flow resistance of the ion wind. In other words, while ensuring that the electrode plate 241 has good purification capacity, it has little impact on the flow resistance of the ion wind, which is conducive to improving the safety and stability of the ion wind component 100.

[0185] An air handling apparatus 1000 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0186] An air treatment device 1000 according to a second aspect of the present invention includes: the above-described ion wind assembly 100.

[0187] In some embodiments, such as Figure 1As shown, the air handling unit 1000 includes a housing 200, a heat exchanger 300, and an ionizing air assembly 100. The housing 200 forms an internal receiving space, within which the heat exchanger 300 and the ionizing air assembly 100 are located. The heat exchanger 300 is positioned to the left of the ionizing air assembly 100. Air inlets 201 communicating with the receiving cavity are formed on the upper and lower sides of the housing 200. For example, the air handling unit 1000 can be wall-mounted, allowing air from outside the space to enter the receiving cavity and exchange heat with the heat exchanger 300. Furthermore, an air outlet 202 is formed on the housing 200, directly opposite the receiving module 2. Thus, the gas, after heat exchange by the heat exchanger 300, is discharged through the air outlet 202 under the action of the ionizing air generated by the ionizing air assembly 100, thereby completing the air conditioning process.

[0188] According to the embodiment of the present invention, the air handling equipment 1000, by setting the above-mentioned ion wind component 100, can achieve impeller-free air delivery, low noise, large air volume, and the ion wind component 100 discharges more evenly and stably, without producing sparking noise, thus improving safety.
