[0002] The sources of suspended particulate matter in indoor air are complex, long-term, and serious, and they are the main pollutants in indoor air. When the mass concentration of indoor inhalable particulate matter reaches 200μg / m³, the incidence of chronic respiratory diseases will increase significantly, and when the mass concentration reaches 800μg / m³, the mortality rate of respiratory diseases and heart disease will increase significantly.

[0003] In related technologies, plasma is generated by direct current corona discharge to remove coarse particles in the room.

[0034] See also Figure 1 and Figure 2 The purification device 100 provided in one embodiment of the present application includes at least two layers of insulating substrates 10 and multiple groups of discharge components 30. All insulating substrates 10 are arranged at intervals along a first direction (corresponding to the X direction in the figure), and flow passages 11 are formed between adjacent insulating substrates 10. Adjacent flow passages 11 are connected. The multiple groups of discharge components 30 are respectively arranged on at least one side surface of each layer of insulating substrate 10 facing the adjacent insulating substrate 10, and are located in the flow passage 11.

[0035] It can be understood that all the insulating substrates 10 can be arranged parallel to each other and perpendicular to the first direction. If the purification device 100 includes two layers of insulating substrates 10, the two layers of insulating substrates 10 are provided with discharge components 30 on the surfaces facing each other. If the purification device 100 includes at least three layers of insulating substrates 10, all the insulating substrates 10 include a first insulating substrate 12, at least one second insulating substrate 13 and a third insulating substrate 14 arranged in sequence along the first direction, wherein the first insulating substrate 12 and the third insulating substrate 14 are located at both ends in the first direction, that is, the outer substrate, and the second insulating substrate 13 is located between the first insulating substrate 12 and the third insulating substrate 14, that is, the inner substrate. Multiple groups of discharge components 30 are respectively arranged on at least one side of each layer of insulating substrate 10 facing the adjacent insulating substrate 10, which means that the outer substrate is provided with a discharge component 30 on the surface facing the inner side, and the inner substrate is provided with a discharge component 30 on at least one side in the first direction. Specifically, the inner substrate can be provided with a discharge component 30 on both sides. In addition, the purification device 100 may also include a housing 50, and the insulating substrate 10 is arranged in the housing 50.

[0036] The flow passages 11 formed between adjacent insulating substrates 10 are used for air circulation, and the discharge assembly 30 disposed on the surface of the insulating substrate 10 is naturally located in the flow passages 11. Adjacent flow passages 11 are flow passages 11 located on both sides of the same insulating substrate 10, and the two are connected, indicating that air can flow from the flow passage 11 on one side of an insulating substrate 10 to the flow passage 11 on the other side.

[0037] An air inlet and an air outlet connected to the flow channel 11 may also be formed on the outer substrate. Air flows into the flow channel 11 from the air inlet, flows through the flow channels 11 of different layers in sequence, and finally flows out from the air outlet.

[0038] Specifically, at least part of the insulating substrate 10 has a through hole 15 connecting the two sides thereof. For the outer substrate, a through hole 15 is provided thereon, and the through hole 15 can be used as an air inlet or an air outlet. For the inner substrate, a through hole 15 is provided thereon, and the flow passages 11 formed on both sides thereof (i.e., adjacent flow passages 11) are connected through the through hole 15 provided thereon.

[0039] It can be understood that the discharge component 30 is connected to a high-voltage DC power supply, and can charge the airflow passing through by discharge, thereby charging the particles in the airflow. When in use, some of the multiple groups of discharge components 30 are connected to the positive high-voltage DC power supply 300 for positive high-voltage discharge, and some are connected to the negative high-voltage DC power supply 400 for negative high-voltage discharge. The discharge components 30 connected to DC power supplies of different properties can make the particles carry charges of different properties, and after the air is charged by the discharge components 30 connected to DC power supplies of different properties in turn, the particles it carries will condense and condense into larger particles. In addition, the insulation performance of the insulating substrate 10 should ensure that it can work normally under the working voltage of the discharge component 30 without being broken down.

[0040] The purification device 100 is provided with a plurality of discharge components 30 through a multi-layer insulating substrate 10, and the air flows through the flow passages 11 between different layers of insulating substrates 10, and is charged by different discharge components 30 in the flow passages 11. In this way, the stacked design can stack more discharge components 30 in the purification device 100, and the air flowing along the flow passages 11 can receive discharges of different properties successively, thereby causing the particles carried by the air to condense, and causing the small-size particles to condense into particles with larger particle sizes, so that the air can be further removed by discharge or filtration, thereby improving the removal efficiency.

[0041] Please also read Figures 3 to 5 Furthermore, the discharge components 30 respectively located on the surfaces of adjacent insulating substrates 10 facing each other are staggered and at least partially overlap in the first direction.

[0042] In other words, the projections of the discharge component 30 on one surface of the insulating substrate 10 and the discharge component 30 on the surface of the adjacent insulating substrate 10 along the first direction on the plane perpendicular to the first direction do not overlap with each other, but are staggered.

[0043] If the end of the discharge component 30 away from the insulating substrate 10 on which it is located in the first direction is the top, the height of the top relative to the insulating substrate 10 on which it is located is h, and the distance between the top and the insulating substrate 10 facing the surface of the insulating substrate 10 on which it is located is d, then the discharge components 30 located on the surfaces of adjacent insulating substrates 10 facing each other at least partially overlap in the first direction, indicating that d<h.

[0044] In this way, the discharge components 30 on the mutually facing surfaces of adjacent insulating substrates 10 are staggered so that the adjacent insulating substrates 10 can be as close as possible in the first direction, thereby effectively reducing the volume of the purification device 100 and improving space utilization.

[0045] In some embodiments, each insulating substrate 10 has a through hole 15 connecting both sides thereof. The discharge component 30 has a discharge space, and one end of the discharge component 30 away from the insulating substrate 10 on which it is located in the first direction is configured as an open end connected to the discharge space, and the open end faces the through hole 15 of the adjacent insulating substrate 10. The discharge component 30 also has a vent hole, which connects the inside and outside of the discharge space along a direction intersecting the first direction.

[0046] It can be understood that adjacent flow channels 11 are connected through through holes 15, and the through holes 15 can be, but are not limited to, a hole array composed of a plurality of small holes, and the diameter of the small holes ranges from 3 mm to 7 mm, and can be specifically 3 mm, 5 mm or 7 mm, etc., to reduce the running wind resistance and ensure the normal entry of air. The insulating substrate 10 is provided with through holes 15 facing upward at the opening end of the discharge assembly 30.

[0047] The open end is connected to the discharge space along the first direction, and one of the open end and the air hole is used for air intake of the discharge space, and the other is used for air discharge of the discharge space. When in use, air can pass through the outer substrate through the through hole 15 as an air inlet, enter the discharge space of the corresponding discharge assembly 30 from the open end facing the through hole 15, and after receiving its charge, flow out of the discharge assembly 30 through the air hole, and then flow into the discharge space of the adjacent discharge assembly 30 through the air hole, receive charge again, and then pass through the next insulating substrate 10 from the open end of the adjacent discharge assembly 30 through the through hole 15 it faces.

[0048] In this way, the air can flow in a circuitous manner between different insulating substrates 10, which helps to extend its flow distance and enhance the charging and dust removal effects.

[0049] Furthermore, the discharge assembly 30 includes a first electrode 31 and a second electrode 32. The first electrode 31 is configured to be disposed on the insulating substrate 10 along a first direction in a longitudinal direction. The second electrode 32 is disposed around the first electrode 31 to enclose a discharge space. One end of the second electrode 32 is formed as an open end, and a vent hole is disposed on the second electrode 32.

[0050] Figure 1 In the figure, the arrow indicates the air flow direction, and the dotted line indicates the structure through which air can pass, wherein the vertical dotted line corresponds to the through hole 15 area, and the horizontal dotted line corresponds to the air vent area.

[0051] The insulating substrate 10 on which the first electrode 31 is provided is defined as the insulating substrate 10 provided on the discharge assembly 30. It can be understood that both ends of the second electrode 32 can contact the two adjacent insulating substrates 10 respectively, and in this case, it can be provided on at least one of them, which is not specifically limited here.

[0052] The first electrode 31 may be a needle-shaped electrode or a rod-shaped electrode, and the radius of curvature is controlled to be 1 mm-2 mm. The second electrode 32 may be cylindrically arranged around the first electrode 31, and the two are coaxially arranged.

[0053] All the second electrodes 32 are grounded. Specifically, all the second electrodes 32 are connected to the ground terminal 200 . The first electrode 31 can be connected to the positive high-voltage DC power supply 300 or the negative high-voltage DC power supply 400 .

[0054] In this way, the first electrode 31 can discharge relative to the second electrode 32 and charge the air in the discharge space, so that the particles are fully charged.

[0055] Further, the second electrode 32 is a mesh electrode, and the mesh holes of the mesh electrode serve as air holes. Specifically, the second electrode 32 can be made of a metal mesh, and the mesh number of the metal mesh can range from 30 mesh to 90 mesh, and specifically can be 30 mesh, 40 mesh, 50 mesh, 60 mesh, 70 mesh, 80 mesh or 90 mesh, etc.

[0056] Thus, the first electrode 31 and the second electrode 32 form a needle-net discharge form. At the same time, such first electrode 31 and second electrode 32 are also convenient for maintenance and cleaning, and dirt can be effectively removed by simple blowing or flushing.

[0057] In some embodiments, each insulating substrate 10 is disposed on a surface facing the adjacent insulating substrate 10 along a second direction (corresponding to Figure 1 At least two discharge assemblies 30 are provided in a second direction (in a Y direction), and the discharge assemblies 30 located on surfaces of adjacent insulating substrates 10 facing each other are alternately arranged in a second direction, wherein the second direction intersects the first direction.

[0058] An avoidance space is formed between two adjacent discharge components 30 in the second direction on each insulating substrate 10, and the avoidance space is used to accommodate the discharge components 30 on the surfaces of adjacent insulating substrates 10, so that the discharge components 30 on the surfaces of adjacent insulating substrates 10 facing each other can at least partially overlap in the first direction through the avoidance space.

[0059] Since the discharge components 30 on the mutually facing surfaces of adjacent insulating substrates 10 are alternately arranged along the second direction, correspondingly, on the same insulating substrate 10, the discharge components 30 and the through holes 15 thereon are alternately arranged in the second direction.

[0060] In this way, as many discharge components 30 as possible can be arranged between two adjacent insulating substrates 10, so as to maximize the use of the space between the adjacent insulating substrates 10 and facilitate the separate electrical connection of the discharge components 30 on different insulating substrates 10.

[0061] Please also read Figure 6In some embodiments, each insulating substrate 10 is disposed in a third direction (corresponding to Figure 6 At least two rows of discharge components 30 are arranged in the first direction, the second direction and the third direction, and the first direction, the second direction and the third direction intersect each other. It can be understood that the number of rows in the second direction and the number of columns in the third direction of the discharge components 30 between two adjacent insulating substrates 10 can be adjusted according to the size of the space to be applied and the different air volumes, and are not specifically limited here. For ease of understanding, the following embodiments are all described by taking the first direction, the second direction and the third direction as being perpendicular to each other.

[0062] In some embodiments, the first electrodes 31 disposed on the same side surface of the same insulating substrate 10 are connected to a DC power source with the same polarity. The first electrodes 31 disposed on mutually facing surfaces of adjacent insulating substrates 10 are respectively connected to DC power sources with different polarities.

[0063] The first electrodes 31 disposed on the same side surface of the same insulating substrate 10 can be connected to the same power line.

[0064] In this way, the discharge components 30 located on the surfaces of adjacent insulating substrates 10 facing each other are alternately arranged in the second direction, so that the properties of the DC power supply connected to the first electrodes 31 between the adjacent insulating substrates 10 change alternately in the second direction, and the air flowing in each layer of the flow channel 11 can receive cross-charging.

[0065] Specifically, the first electrodes 31 disposed on the same insulating substrate 10 are connected to a DC power source with the same polarity.

[0066] In this way, the first electrodes 31 provided on the same insulating substrate 10 can be electrically connected together, and the connection method is simpler. In addition, the voltage difference on both sides of the same insulating substrate 10 can be reduced. Compared with the case where the two sides of the same insulating substrate 10 are not connected to the property voltage, the breakdown risk is lower and the requirements for the insulating substrate 10 are also lower.

[0067] In some embodiments, the discharge assembly 30 further includes a fixing ring 33 , one end of the second electrode 32 in the first direction is connected to the insulating substrate 10 , and the fixing ring 33 is disposed at the other end of the second electrode 32 in the first direction.

[0068] It can be understood that the fixing ring 33 is a hollow ring that allows air to pass through. When the second electrode 32 of the discharge assembly 30 is connected to the same insulating substrate 10 as the first electrode 31, the end of the second electrode 32 away from the insulating substrate 10 is the open end, and the fixing ring 33 is disposed at the open end.

[0069] The fixing ring 33 can fix the second electrode 32, making it stronger and less prone to deformation, while reducing burrs and sharp edges on the edges, thereby reducing the risk of local abnormal sparking.

[0070] In some embodiments, the entire insulating substrate 10 includes a first insulating substrate 12, at least one second insulating substrate 13 and a third insulating substrate 14 arranged sequentially along a first direction, an air inlet is formed on the first insulating substrate 12, an air outlet is formed on the third insulating substrate 14, and the second insulating substrate 13 has a through hole 15 connecting its two sides.

[0071] In other words, the purification device 100 includes at least three layers of insulating substrates 10, the air inlet of the first insulating substrate 12 and the air outlet of the third insulating substrate 14 are served by respective through holes 15, and the opening ends of the discharge components 30 on the second insulating substrates 13 adjacent to each other are facing upward.

[0072] The purification device 100 includes at least three layers of insulating substrates 10, and more discharge components 30 can be set. Taking the example that air can flow through two discharge components 30 between two adjacent insulating substrates 10, the air can be pre-charged in the discharge space of at least one discharge component 30, and condensed in the discharge space of the second discharge component 30 to obtain large particles, which are adsorbed on the mesh second electrode 32. In the discharge space of the third discharge component 30, the large particles can be recharged and adsorbed on the mesh second electrode 32, thereby improving the condensation and dust removal effect. If the purification device 100 includes more than three layers of insulating substrates 10, the air can be repeatedly cross-charged to improve the condensation and dust removal effect.

[0073] The discharge assembly 30 includes a first discharge assembly 34, a second discharge assembly 35 and a third discharge assembly 36. At least two first discharge assemblies 34 are provided on the surface of the first insulating substrate 12 facing the second insulating substrate 13, at least two third discharge assemblies 36 are provided on the surface of the third insulating substrate 14 facing the second insulating substrate 13, and at least two second discharge assemblies 35 are provided on both side surfaces of the second insulating substrate 13; the first discharge assemblies 34 and the second discharge assemblies 35 on the adjacent second insulating substrate 13 are alternately arranged in the second direction, and the third discharge assemblies 36 and the second discharge assemblies 35 on the adjacent second insulating substrate 13 are alternately arranged in the second direction.

[0074] It can be understood that when there are multiple second insulating substrates 13 , the second discharge components 35 on adjacent second insulating substrates 13 are also alternately arranged.

[0075] In one embodiment, the purification device 100 includes three layers of insulating substrates 10, namely, a first insulating substrate 12, a second insulating substrate 13, and a third insulating substrate 14, wherein the first electrodes 31 on the first insulating substrate 12 and the third insulating substrate 14 are both connected to a positive high-voltage DC power supply 300, the first electrodes 31 on the second insulating substrate 13 are both connected to a negative high-voltage DC power supply 400, and the second discharge components 35 are symmetrically arranged on both sides of the second insulating substrate 13. When in use, air first passes through the air inlet of the first insulating substrate 12 and the open end of the second electrode 32 of the second discharge component 35 in sequence, enters the discharge space of the second discharge component 35, and after being charged under the action of the first electrode 31 connected to the negative high-voltage DC power supply 400, it flows into the discharge space of the first discharge component 34 in sequence through the mesh of the second electrode 32 of the second discharge component 35 and the mesh of the second electrode 32 of the adjacent first discharge component 34, and is charged under the action of the first electrode 31 connected to the positive high-voltage DC power supply 300, and condenses, and small particles condense into large particles attached to the mesh-shaped second electrode 32. Then, the air enters the discharge space of the third discharge component 36 through the open end of the first discharge component 34, the through hole 15 on the second insulating substrate 13 and the open end of the third discharge component 36, and is charged under the action of the first electrode 31 connected to the positive high-voltage DC power supply 300, ensuring that the negative ions excited in the front can be fully condensed and removed. Then, the air flows into the discharge space of the second discharge component 35 through the mesh of the second electrode 32 of the third discharge component 36 and the mesh of the second electrode 32 of the adjacent second discharge component 35, neutralizing the positive ions in the front, so that the air discharged at last has oxygen negative ions. Finally, the air flows through the open end of the second discharge component 35 and the air outlet of the third insulating substrate 14 in sequence and is discharged from the purification device 100.

[0076] In this way, the purification device 100 forms a two-layer composite purification structure. By cross-arranging the polarity of the charged electrodes, the electrocoagulation of positive and negative ions is realized, which can effectively remove tiny particles in the air; by rationally arranging the positions of the purification components and designing a cross-shaped movement path, the processing time of the polluted gas is increased. Breaking through the thickness defects of the traditional electrocoagulation device, an ultra-thin and efficient purification device 100 is formed. In addition, the air is first excited to charge the negative polarity by the negative high-voltage electrode because the excitation voltage required for the negative high voltage is lower, and the mass of the electrons is smaller, so it is easier to obtain higher kinetic energy, and a large number of active particles can be generated in a short time compared with the positive high voltage.

[0077] The present application also provides an air conditioning device, including the above-mentioned purification device 100. The air conditioning device may be, but is not limited to, an air conditioner, an air purifier, a dehumidifier, or other device capable of processing air, and while the air conditioning device is working, the purification device 100 is used to improve the removal effect of small-size particles and improve the air quality.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
