The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

An ionic wind assembly 100 according to an embodiment of the present invention is described below with reference to fig. 1-25.

Referring to fig. 1-25, an ion wind assembly 100 according to an embodiment of the first aspect of the utility model comprises: the device comprises a discharge module 1, a receiving module 2 and a power supply module.

The discharge module 1 may include at least one discharge unit 10, for example, the discharge module 1 may include one discharge unit 10, or may include a plurality of discharge units 10. The discharge cell 10 may include a dielectric layer 13, a first electrode layer 11, and a second electrode layer 12, the first electrode layer 11, the second electrode layer 12, and the dielectric layer 13 being disposed to overlap, and the first electrode layer 11 and the second electrode layer 12 being respectively located at opposite sides in a thickness direction of the dielectric layer 13. 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, which may be parallel to the plane of the dielectric layer 13.

The receiving module 2 may include: the mesh electrode 21 and the mesh electrode 21 may include a plurality of electrode wires 211, and the plurality of electrode wires 211 are interlaced to form the ventilation mesh 212, so that the receiving module 2 adopts the mesh electrode 21, and the electrode wires 211 around the ventilation mesh 212 may generate an electric field, so that the electric field at each place in the ventilation mesh 212 area is relatively balanced, and the wind outlet of the charged particles through the ventilation mesh 212 at a certain speed is facilitated.

The receiving module 2 can be arranged at a distance from the discharging module 1, and the power supply module is respectively electrically connected with the first electrode layer 11, the second electrode layer 12 and the receiving module 2 to drive the discharging module 1 to generate charged particles through dielectric barrier discharge, and a first electric field is formed between the discharging module 1 and the receiving module 2 to drive the charged particles to migrate to the receiving module 2 to form ion wind; in the direction of the first electric field, the first projection and the second projection are at least partially staggered to form a second electric field consistent with the first electric field in the direction outside the discharge module 1, and the second electric field can initially accelerate charged particles generated by ionizing air in the discharge module 1 to improve the migration velocity of the charged particles, so that ion wind with initial kinetic energy is formed.

For example, as shown in fig. 11 to 22, the discharge module 1 and the receiving module 2 may be arranged at intervals in the left-right direction, a first electric field is formed between the discharge module 1 and the receiving module 2, and the direction of the first electric field is from the discharge module 1 to the receiving module 2. Wherein, the discharge module 1 can adopt SDBD (dielectric barrier discharge along surface) discharge, the arrangement direction of the first electrode layer 11, the dielectric layer and the second electrode layer 12 (or the thickness direction of the discharge module 1) is perpendicular to the direction of the first electric field, the first electrode layer 11 can be used as a high voltage end to generate charged particles, the second electrode layer 12 can be used as a ground end to form an asymmetric electric field with the high voltage end, i.e. a second electric field, the projection of the first electrode layer 11 on the reference plane is a first projection, the projection of the second electrode layer 12 on the reference plane is a second projection, and, in the electric field direction of the first electric field, the first projection and the second projection are at least partially staggered, and the distance between the first projection and the receiving module 2 is larger than the distance between the second projection and the receiving module 2, in this way, the first electrode layer 11 and the second electrode layer 12 can form the second electric field outside the discharge module 1 in accordance with the direction of the first electric field. The second electric field can initially accelerate the charged particles to make the charged particles have initial kinetic energy, and the first electric field formed between the discharging module 1 and the receiving module 2 can further drive the charged particles to migrate from the discharging module 1 and the receiving module 2 to form ion wind.

According to the ion wind component 100 of the embodiment of the utility model, the discharge module 1 adopts dielectric barrier discharge to generate ions, so that not only can the discharge point be increased to improve the ionization efficiency and the ion generation amount, thereby improving the wind volume, but also the discharge can be more uniform and stable, the abnormal sound of ignition can not be generated, the silent discharge and the silent wind outlet can be realized, and the safety is higher. In addition, the generated ions have initial kinetic energy, the integral air output and air output speed can be further increased, and larger ion wind is generated. Therefore, when the ion wind assembly 100 is used for the air treatment device 1000, the wind wheel-free air supply can be realized, the noise is lower compared with the wind wheel air supply, and the effect of purifying air is also achieved.

Optionally, the first electrode layer 11 is a conductive material, for example, the first electrode layer 11 may be metal such as copper, aluminum, or carbon black, and when the first electrode layer 11 is used to ionize air, in order to enhance the discharge capability of the first electrode layer 11, a conductive coating may be disposed on the surface of the first electrode layer 11, for example, the conductive coating may be a graphite layer, a graphene layer, a fullerene layer, or the like.

Optionally, the second electrode layer 12 is a conductive material, for example, the second electrode layer 12 may be metal such as copper, aluminum, or carbon black, and when the second electrode layer 12 is used to ionize air, in order to enhance the discharge capability of the second electrode layer 12, a conductive coating may be disposed on the surface of the second electrode layer 12, for example, the conductive coating may be a graphite layer, a graphene layer, a fullerene layer, or the like.

According to some embodiments of the utility model, referring to fig. 1-2 and 6-7, at least part of the first projection coincides with the second projection in the direction of the first electric field. That is, in the direction of the first electric field, it may be that all of the first projection coincides with the second projection, at which time the first projection is located within the second projection; alternatively, a part of the first projection may overlap a part of the second projection. In this way, in the area where the first projection and the second projection do not overlap, an asymmetric electric field, that is, the second electric field described above, may be formed, and the formation of the second electric field is favorable for initially accelerating the charged particles generated around the discharge module 1, so as to increase the speed of migration of the charged particles to the receiving module 2, thereby forming an ion wind with a higher wind speed.

In other embodiments, referring to fig. 3-4 and fig. 8-9, in the direction of the first electric field, the first projection and the second projection are completely staggered, so that on one hand, the efficiency of the discharge module 1 for ionizing air can be increased, and on the other hand, the range of the second electric field can be advantageously increased, so that the second electric field can increase the migration speed of the charged particles in the air to form an ion wind with a larger wind volume and wind speed.

In some alternative embodiments of the present invention, referring to fig. 3-4 and 8-9, the distance s1 between the first projection and the second projection in the direction of the first electric field ranges from 0mm to 20mm, or from 0mm to 10mm, or from 0mm to 5 mm. That is, in the case where the first projection is completely staggered from the second projection, the spacing s1 between the first projection and the second projection may be 0mm, 3mm, 5mm, 7mm, 10mm, 15mm, 18mm, or 20mm, wherein preferably the spacing s1 between the first projection and the second projection ranges from 0mm to 10mm, and more preferably the spacing s1 between the first projection and the second projection in the direction of the first electric field ranges from 0mm to 5 mm. In other words, in the direction of the first electric field, under the condition that the first projection and the second projection are staggered, the closer the distance between the first projection and the second projection is, the better, so that the charged particles generated by the ionization of air by the first electrode layer 11 or the second electrode layer 12 can be just in the second electric field or be closer to the center of the second electric field during generation, the initial kinetic energy is more easily obtained, the migration speed is improved, and ion wind is formed.

According to some embodiments of the present invention, the width L1 of the first electrode layer 11 ranges from 1mm to 50mm, or from 1mm to 20mm, or from 5mm to 10mm in the direction of the first electric field. That is, in the direction of the first electric field, the width L1 of the first electrode layer 11 may take the following value: 1mm, 5mm, 8mm, 10mm, 15mm, 20mm, 28mm, 40mm or 50mm, preferably the width of the first electrode layer 11 ranges from 1mm to 20mm, more preferably the width L1 of the first electrode layer 11 ranges from 5mm to 10 mm. Therefore, the wind resistance of the discharge module 1 to ion wind can be prevented from increasing due to the overlarge width of the first electrode layer 11, the effect of the discharge module 1 to air ceremony caused by the undersize width of the first electrode layer 11 can be prevented from deteriorating, and the generated air volume is small.

According to some embodiments of the utility model, the thickness t1 of the first electrode layer 11 has a value in the range of 0.1-2mm, or 0.1-1mm, or 0.1-0.5 mm. That is, the thickness t1 of the first electrode layer 11 is 0.1mm, 0.3mm, 0.5mm, 0.8mm, 1mm, 1.5mm or 2mm, preferably, the thickness t1 of the first electrode layer 11 is in the range of 0.1mm to 1mm, and more preferably, the thickness t1 of the first electrode layer 11 is in the range of 0.1mm to 0.5 mm. In this way, in the case where the structural stability of the first electrode layer 11 is ensured, the smaller the thickness of the first electrode layer 11 is, the higher the ionization efficiency of the first electrode layer 11 with respect to air is, the more charged particles are generated, and the larger the air volume of the ion wind is.

According to some embodiments of the present invention, the width L2 of the second electrode layer 12 in the direction of the first electric field may range from 1mm to 50mm, or from 10mm to 40mm, or from 10mm to 20mm, that is, the width L2 of the second electrode layer 12 in the direction of the first electric field may range from: 1mm, 5mm, 8mm, 10mm, 15mm, 20mm, 28mm, 40mm or 50mm, preferably, the value range of the width of the second electrode layer 12 is 10mm-40mm, more preferably, the value range of the width L2 of the second electrode layer 12 is 10mm-20mm, so, both can avoid causing the windage resistance increase of the discharge module 1 to the ion wind because the width of the second electrode layer 12 is too big, can avoid the effect deterioration of the discharge module 1 to the air ceremony that the width undersize of the second electrode layer 12 leads to again, and then lead to the generated amount of wind to be less.

Optionally, referring to fig. 13 and 17, in the direction of the first electric field, a width of one of the first electrode layer 11 and the second electrode layer 12 adjacent to the receiving module 2 is greater than a width of the other, for example, as shown in fig. 13, in the direction of the first electric field, a distance between the second electrode layer 12 and the receiving module 2 is smaller than a distance between the first electrode layer 11 and the receiving module 2, and a width of the second electrode layer 12 is greater than a width of the second electrode layer 12, so that, in a case that the width of the whole discharge unit 10 is constant, that is, the wind resistance is constant, it is ensured that the electric field range of the second electric field is greater, and when the first electrode layer 11 ionizes air to generate charged particles, a path of the second electric field through which the charged particles pass is longer, and an increase in speed is also greater, thereby increasing the wind speed of the ion wind, and further increasing the wind outlet effect.

According to some embodiments of the present invention, the thickness t2 of the dielectric layer 13 ranges from 0.1mm to 10mm, or from 0.1mm to 3mm, for example, the thickness t2 of the dielectric layer 13 ranges from 0.1mm, 0.5mm, 1mm, 3mm, 5mm, 8mm, or 10mm, and preferably, the thickness t2 of the dielectric layer 13 ranges from 0.1mm to 3mm, so that it is possible to prevent the discharge cell 10 from being sufficiently ionized when the thickness of the dielectric layer 13 is too large, and prevent the first electrode layer 11 and the second electrode layer 12 from being sufficiently broken down when the thickness of the dielectric layer 13 is too small, for example, less than 0.1 mm.

Alternatively, the dielectric layer 13 is a dielectric material piece with high resistivity and high dielectric constant, for example, the dielectric layer 13 may be a teflon piece, an epoxy piece, a quartz piece, a glass piece or an alumina piece, and the dielectric layer 13 may be set to a suitable thickness according to the material of the dielectric layer 13.

According to some embodiments of the present invention, in the direction of the first electric field, the width L3 of the discharge cell 10 may range from 10mm to 100mm, or from 10mm to 50mm, that is, in the direction of the first electric field, the width L3 of the discharge cell 10 may range from 10mm, 30mm, 40mm, 50mm, 75mm, 90mm, or 100mm, and preferably, the width L3 of the discharge cell 10 may range from 10mm to 50mm, so that it is possible to avoid that the width of the discharge cell 10 is too small, which results in the ionization efficiency of the discharge module 1 being reduced, and the volume of the ion wind being reduced, and to avoid that the width of the discharge cell 10 is too large, which results in the wind resistance of the ion wind being increased, and the volume loss being increased.

According to some embodiments of the present invention, referring to fig. 1 to 4, the discharge unit 10 may include a dielectric layer 13, a first electrode layer 11 and a second electrode layer 12, in which one of the first electrode layer 11 and the second electrode layer 12 may be encapsulated to be isolated from air and the other may be in direct contact with air, for example, the second electrode layer 12 is encapsulated to be isolated from air, and the first electrode layer 11 is in direct contact with air, so that the discharge unit 10 may generate charged particles by unilaterally discharging air; or, referring to fig. 6, the discharge unit 10 may also include two dielectric layers 13, two first electrode layers 11 and one second electrode layer 12, at this time, one second electrode layer 12 is sandwiched between the two dielectric layers 13, and the two first electrode layers 11 are respectively located on the sides of the two dielectric layers 13 far from the second electrode layer 12, at this time, the second electrode layer 12 may be encapsulated to be isolated from the air, so that it may be ensured that both the two first electrode layers 11 of the discharge unit 10 may ionize the air to generate charged particles, and the discharge unit 10 realizes double-sided discharge.

Alternatively, referring to fig. 7 to 10, the discharge cell 10 may also include a dielectric layer 13, two first electrode layers 11 and a second electrode layer 12, in which case, an embedded groove may be disposed on the dielectric layer 13, the embedded groove may be located in the center of the dielectric layer 13 in the thickness direction and extend in the direction perpendicular to the thickness direction, the second electrode layer 12 may be embedded in the embedded groove, the two first electrode layers 11 are respectively located on both sides of the dielectric layer 13 in the thickness direction, and at this time, the second electrode layer 12 may be sealed to be isolated from the air, so that it may be ensured that both the first electrode layers 11 of the discharge cell 10 may ionize the air to generate charged particles, and the discharge cell 10 realizes double-sided discharge.

According to some embodiments of the present invention, the discharge module 1 may include a plurality of discharge cells 10, the plurality of discharge cells 10 may be disposed at intervals in a thickness direction, and the plurality of discharge cells 10 are disposed in parallel, so that the air ionization capacity of the discharge module 1 may be further increased, the ionization efficiency may be improved, and the volume of the ion wind may be further increased.

Alternatively, referring to fig. 19, when the discharge module 1 has a plurality of discharge cells 10, the plurality of first electrode layers 11 of the plurality of discharge cells 10 may be connected by the first connection member 14, and correspondingly, the plurality of second electrode layers 12 of the plurality of discharge cells 10 may be connected by the second connection member 15, so that it is only necessary to respectively make the first connection member 14 and the second connection member 15 to be correspondingly coupled with the power supply module, and thus, the internal wiring of the ion wind assembly 100 may be simplified, facilitating assembly and maintenance.

According to some embodiments of the present invention, the discharge module 1 may include at least three discharge units 10, the three discharge units 10 are arranged at intervals, and the intervals between every two adjacent discharge units 10 are equal, so that, on one hand, ionization generated by the three discharge units 10 is more balanced, and on the other hand, wind resistance between every two adjacent discharge units 10 is the same, so that wind outlet of generated ion wind is more uniform, and the effect is better.

Of course, the present invention is not limited thereto, and the discharge module 1 may also include a plurality of discharge cells 10, the plurality of discharge cells 10 are arranged at intervals, and the distance s2 between two adjacent discharge cells 10 ranges from 10mm to 100mm, or from 10mm to 80mm, or from 10mm to 20mm, that is, the distance s2 between two adjacent discharge cells 10 may range from 10mm, 15mm, 20mm, 50mm, 60mm, 80mm, 90mm, or 100mm, preferably, the distance s2 between two adjacent discharge cells 10 ranges from 10mm to 80mm, and more preferably, the distance s2 between two adjacent discharge cells 10 ranges from 10mm to 20mm, so that the plurality of discharge cells 10 may improve the air ionization efficiency of the discharge module 1 to generate a larger air volume, and the distance between two adjacent discharge cells 10 is set to 10mm to 100mm, the wind resistance is favorably reduced, the discharge units 10 can be ensured to fully ionize the air adjacent to the discharge units in the space, the ionization efficiency is further ensured, and in addition, the mutual interference of the adjacent discharge units 10 can be avoided to a certain extent.

According to some embodiments of the present invention, the discharge module 1 includes a plurality of discharge units 10 arranged at intervals, and the distances between each discharge unit 10 and the receiving module 2 are equal, so that, on one hand, ionization generated by three discharge units 10 is more balanced, and on the other hand, wind resistances between two adjacent discharge units 10 are the same, so that the wind outlet of the generated ion wind is more uniform, and the effect is better.

According to some embodiments of the present invention, the distance s3 between the discharge unit 10 and the receiving module 2 ranges from 3mm to 50mm, or from 5mm to 30mm, or from 10mm to 20mm, that is, the distance s3 between the discharge unit 10 and the receiving module 2 may range from 3mm, 5mm, 8mm, 10mm, 15mm, 20mm, 25mm, 30mm, 40mm, or 50mm, so that when the distance between the discharge unit 10 and the receiving module 2 is too large, for example, greater than 50mm, the field strength of the electric field between the discharge unit 10 and the receiving module 2 is too weak, the driving and accelerating effect of the electric field on the charged particles is too weak, and the charged particles are difficult to effectively migrate from the discharge unit 10 side to the receiving module 2 side to form a stable ion wind, or when the distance between the discharge unit 10 and the receiving module 2 is too small, for example, less than 3mm, the acceleration distance of the charged particles is shortened, so that the wind speed and the wind outlet efficiency of the ion wind are reduced, and the size of the whole ion wind assembly 100 is favorably ensured to be in a proper range.

Referring to fig. 25, the ignition voltage in the figure is a voltage when the ion wind module 100 starts to generate current, the ignition voltage is a voltage when the voltage between two electrodes of the ion wind module 100 is too high, which may cause an ignition phenomenon, and affects the normal operation of the ion wind module 100, and the voltage when the ignition phenomenon is just generated is the ignition voltage, and the voltage window is the ignition voltage-ignition voltage, which is the normal operating voltage of the ion wind module 100 and is also the adjustable voltage range of the ion wind module 100, wherein s3 is a factor for determining the voltage window, and the value of s3 is adjusted, so that the thickness and the voltage window of the ion wind module 100 may be changed, and the total air output of the ion wind may also be affected.

Moreover, the plate spacing s2 is also an important factor affecting the voltage window, and when the ion wind module 100 is optimized, the above parameters need to be adjusted at the same time to obtain the best wind outlet effect. That is, after the parameters (curvature, material, etc.) of the electrode itself are determined, the parameter adjustment of the ion wind assembly 100 is mainly to adjust the above parameters.

The voltage section to be selected as the operating voltage of the ion wind module 100 is determined according to actual needs, for example, a scene requiring a smaller ion wind volume may be selected, and the ion wind module 100 operating at a low voltage (less than 6kV) may be selected. When strong air supply is needed, the high-voltage (more than 20kV) ion wind assembly 100 is selected, the wind speed and the wind volume of the generated ion wind are higher than those of the ion wind generated under the state, but the problems of safety rules, electromagnetic compatibility, byproducts and the like need to be considered, and meanwhile, a safe feedback signal acquisition circuit needs to be equipped.

Optionally, the high voltage AC power supply unit 4 and the high voltage dc power supply unit 3 both use AC voltage inputs, input voltages AC 85V-AC 265V. The high-voltage alternating-current power supply unit 4 is boosted to 4-6kV through a transformer and then output in a voltage doubling mode, and the output voltage range is 10-30 kV; after rectification, the high-voltage direct-current power supply unit 3 boosts the voltage to 4-6kV through a transformer, outputs direct-current high voltage through voltage doubling, and outputs the output voltage range to 20kV-40 kV; the power supply adopts a full-bridge phase-shift driving circuit, and the voltage is regulated through digital control so as to realize regulation of the ionic wind quantity.

Optionally, the second electrode layer 12 may be packaged to isolate air, and since the direction and magnitude of the current of the high-voltage ac power supply unit 4 are becoming smaller, and the second electrode layer 12 is packaged to isolate air, the second electrode layer 12 may be prevented from ionizing air, thereby disturbing the flow field of the ionic wind generated by the first electrode layer 11.
