As shown in fig. 1, some embodiments of the present invention provide an ionizer 100, the ionizer 100 including: the discharge electrode comprises a fixed ring 11, a metal electric coil 12, a mounting table 13, a plurality of connecting columns 14 and a discharge body 15.

The metal coil 12 is coaxially disposed at an inner ring of the fixed ring 11. Illustratively, the outer diameter of the metal coil 12 is adapted to the inner diameter of the fixing ring 11, and the metal coil 12 can be clamped or fixed on the fixing ring 11 by a fixing member. Wherein, the mounting can select for use buckle, rivet, viscose etc. any have the fixed knot function and do not hinder the circular telegram fixed knot structure of 12 circular telegrams of metal.

In some examples, the metal coil 12 may completely cover the inner ring surface of the fixing ring 11, so that the metal coil 12 can have a larger coverage area and can provide a better charging effect for microorganisms or particles passing through the metal coil 12.

In other examples, the metal coil 12 may partially cover the inner ring of the fixing ring 11, for example, at least one side of the metal coil 12 is shrunk on the surface of the corresponding side of the fixing ring 11, so as to avoid the metal coil 12 from contacting with the conductive object on the surface of one side of the fixing ring 11, and thus the safety of the metal coil 12 during the operation process can be better guaranteed.

The mounting table 13 is connected with the fixing ring 11 through a plurality of connecting columns 14, two ends of each connecting column 14 are respectively connected to the mounting table 13 and the fixing ring 11, the connecting columns can be fixedly connected with the mounting table 13 or the fixing ring 11 or can be detachably connected with the mounting table 13 or the fixing ring 11, and the connecting columns are not limited in the position.

It should be noted that the fixed connection mode may be performed by referring to the existing fixed connection mode (for example, an integrated molding mode, a welding mode, and the like), and the detachable connection mode may be performed by, for example, a snap connection mode, an adhesion mode, and the like, which is not exhaustive.

Furthermore, the mount table 13 is also provided coaxially with the fixed ring 11. In some examples, the diameter of the mounting table 13 is smaller than the inner diameter of the fixing ring 11, so that the air to be purified is less resistant when passing through the fixing ring 11 and blowing toward the mounting table 13, thereby contributing to the improvement of the stability of the ionizer 100 in use.

The discharge body 15 is fixed on the axis of the mounting platform 13, so that the discharge body 15 and the metal coil 12 form an umbrella-shaped enclosure, and microorganisms and particulate matters in the air passing through the fixing ring 11 can be sufficiently charged and decomposed, thereby achieving good air purification effect.

The discharge body 15 is located at least on the side of the mounting table 13 close to the fixing ring 11. In some examples, the mounting table 13 is provided with a fixing groove at an axial center position thereof, one end of the discharge body 15 is fixed in the fixing groove, and the other end of the discharge body 15 faces the fixing ring 11. The fixing grooves are matched to help to form a good fixing effect on the discharge body 15, and the discharge body 15 is prevented from sliding towards the side far away from the fixing ring 11 when air blows to the discharge body 15. Meanwhile, the design length of the discharge body 15 can be shortened, so that the material consumption of the discharge body 15 is saved, and the material cost is saved.

The discharge body 15 and the metal coil 12 output one of positive and negative electricity, respectively. That is, when the discharge body 15 outputs positive electricity, the metal coil 12 outputs negative electricity; alternatively, when the discharge element 15 outputs negative electricity, the metal coil 12 outputs positive electricity.

Illustratively, the discharge body 15 and the metal coil 12 output one of high positive voltage and high negative voltage, respectively.

With this arrangement, the high voltage positive electricity and the high voltage negative electricity respectively output by the discharge body 15 and the metal electric ring 12 can convert oxygen molecules in the air into positive ions or negative ions, and the positively charged atoms and the negatively charged atoms can search for particles or microorganisms with opposite charges, so as to decompose the microorganisms. In addition, for viruses, positive and negative ions initiate chemical reactions at the cell membrane surface. The positive and negative ions encapsulate the virus and disrupt the protein coat on the outer membrane of the virus to neutralize them.

In some examples, the discharge 15 includes one or more discharge needles. When the discharge needle is arranged one, one end of the discharge needle is matched with the diameter of the fixed slotted hole of the mounting table 13, so that the discharge needle can be mounted and replaced conveniently.

In some examples, the discharge 15 comprises at least one carbon fiber brush. With the arrangement, the carbon fiber brush can reduce the generation of ozone in the working process, the circumference of the carbon fiber brush is small, the quantity of positive ions (or negative ions) released by the carbon fiber brush is large, and the functions of removing microorganisms, adsorbing particles and sterilizing by the ion generator 100 are enhanced. Based on this, the discharge body 15 may be aligned and arranged side by side on the mount table 13 using a plurality of carbon fiber brushes.

In some embodiments, the connecting columns 14 are sequentially arranged around the axis between the mounting table 13 and the fixing ring 11, and one end of any two adjacent connecting columns 14, which is connected with the mounting table 13, is arranged at equal intervals. That is, one ends of the connecting columns 14 are sequentially arranged around the axis of the mounting table 13, and the distances between the connecting points of two adjacent connecting columns 14 on the mounting table 13 are equal. Meanwhile, the connecting columns 14 are sequentially arranged around the axis of the fixing ring 11, and the distance between the connecting points of two adjacent connecting columns 14 on the fixing ring 11 is equal.

In some examples, the connecting column 14 and the mounting table 13 have an included angle of 120 °. Thus, the mount table 13 connected by the plurality of connection posts 14 and the fixing ring 11 are connected with each other with good connectivity and high overall stability. Meanwhile, the distance between the mounting table 13 and the fixing ring 11 is set reasonably, and the air to be purified through the fixing ring 11 can be sufficiently reacted with the discharge body 15 on the mounting table 13, so that the effects of removing microorganisms, adsorbing particles and sterilizing by the ion generator 100 are improved.

In some examples, the two ends of the connecting column 14 can be adhered to the mounting platform 13 and the fixing ring 11 respectively by glue. Of course, the connection mode between the connection column 14 and the mounting table 13 and/or the fixing ring 11 is not limited to this, and in general, the connection column 14 and the mounting table 13 and/or the fixing ring 11 can be easily cleaned and partially replaced by a detachable connection.

In some examples, the number of the connecting columns 14 is three, and the connecting stability between the mounting table 13 and the fixing ring 11 can be better achieved through the three connecting columns 14, so that the use of the connecting columns 14 is saved.

In some examples, the connecting column 14 is made of a porous ceramic material. The porous ceramic material has the characteristic of good insulativity, and is beneficial to the metal electric coil 12 and the discharge body 15 not to generate interference with each other in the working process; the porous ceramic material also has the characteristic of high temperature resistance, so that the damage of the connecting column 14 caused by a large amount of heat generated by the metal electric coil 12 and the discharge body 15 in the working process can be effectively avoided.

In some examples, the connecting column 14 is coated externally with an ozone catalyst. The ozone catalyst can remove ozone originally existing in the air and ozone generated by corona generated in the electrifying process of the ion generator 100, thereby being beneficial to improving the purifying effect of the ion generator 100 on the air to be purified.

As an example, the ozone catalyst may employ a catalyst including at least manganese dioxide. For example, the ozone catalyst may be a catalyst prepared by mixing manganese dioxide and glycerin.

In some examples, the connecting column 14 may be a connecting column 14 of porous ceramic material and coated with the ozone catalyst described above. The surface of the connecting column 14 made of porous ceramic material has a plurality of pores with diameter larger than 30 μm, so that the surface area of the connecting column 14 is relatively large, the contact area between the air to be purified and the connecting column 14 can be increased, and the air purification effect can be improved.

Based on this, the ozone catalyst of the connecting column 14 can be manufactured in the following manner: before installation, the connecting column 14 can be immersed in a liquid containing manganese dioxide and glycerol for 4-6 hours, then placed in a drying furnace, heated to 60-80 degrees, and dried for 60 minutes for use.

In some embodiments, the connection column 14 is a hollow cylinder, and a conductive wire is disposed in the connection column 14, and one end of the conductive wire is connected to the discharge body 15. That is, the discharge bodies 15 can be electrically conducted through the conductive wires located inside the connection posts 14, so that the conductive wires connected to the discharge bodies 15 are prevented from being exposed to the outside and being easily damaged.

As shown in fig. 2, some embodiments of the present invention further provide an ion generating device 200, wherein the ion generating device 200 includes two power supply terminals, a PCB board 20, and the ionizer 100 according to any of the above embodiments.

The two power supply access ends are respectively connected with a positive power supply and a negative power supply. Illustratively, the positive power supply and the negative power supply are both high frequency power supplies.

The PCB board 20 has at least one vent hole 21, and the PCB board 20 is coupled to the two power supply access terminals.

The fixing ring 11 of the ionizer 100 is detachably fixed to the PCB board 20. For example, referring to fig. 1, the fixing ring 11 is provided with a plurality of first mounting holes 16 along a circumferential direction thereof, and the PCB 20 is provided with a plurality of second mounting holes on a circumferential side of the vent hole 21, so that the ion generator 100 can be mounted on the PCB 20 by inserting screws into the first mounting holes 16 and the second mounting holes.

The vent hole 21 exposes the metal coil 12 of the ionizer 100, so that the gas to be purified passing through the vent hole 21 can be sufficiently purified by the metal coil 12 and the discharge body 15 to provide a good purification effect.

In some examples, the axis of the vent 21 is collinear with the axis of the ionizer 100.

The PCB board 20 is coupled to the metal coil 12 through a first metal wire, and the metal coil 12 is finally connected to a positive power supply (or a negative power supply) through the first metal wire and a set of copper wires laid in the PCB board 20. The PCB board 20 is coupled to the discharge body 15 through a second metal wire, and the discharge body 15 is finally connected to a negative power supply (or a positive power supply) through the second metal wire and another set of copper wires laid in the PCB board 20. When the metal electric ring 12 is connected to a positive power supply and the discharge body 15 is connected to a negative power supply, the metal electric ring 12 outputs positive electricity, and the discharge body 15 outputs negative electricity; when the metal coil 12 is connected to a negative power supply and the discharge element 15 is connected to a positive power supply, the metal coil 12 outputs negative electricity and the discharge element 15 outputs positive electricity.

In some embodiments, the ventilation holes 21 are provided in multiple groups and arranged in an array in multiple rows and multiple columns; the number of the vent holes 21 corresponds one-to-one to the number of the ionizers 100. That is, the plurality of sets of ionizers 100 are distributed in an array on the PCB 20, and thus, the plurality of sets of ionizers 100 form a corona area, so that a region can be purified, and thus, the air purification efficiency of the region can be improved.

In some examples, the ion generating device 200 has at least two adjacent ionizers 100 with different electrical outputs from the metal coils 12.

In this arrangement, the electric properties of the particulate matter, the microorganisms, and the like in the air passing through the first ionizer 100 (one of the ionizers 100 corresponding to the two adjacent metal coils 12 having different output electric properties) are opposite to the electric properties of the particulate matter, the microorganisms, and the like in the air passing through the second ionizer 100 (the other one of the ionizers 100 corresponding to the two adjacent metal coils 12 having different output electric properties). According to ohm's law, since the abnormal charges (i.e. the charges opposite to each other) attract each other, the positively charged particles and the microorganisms attract each other, and the negatively charged particles and the microorganisms release energy during neutralization, so that the bacteria and viruses in the air can be effectively killed. In addition, the particles and the microorganisms with positive electricity and the particles and the microorganisms with negative electricity are mutually attracted and then polymerized to form larger particles, so that the particles are more easily adsorbed or obtained to remove the part of substances, and further a good air purification effect is achieved.

Illustratively, the ion generating device 200 has at least two rows (or two columns) of adjacent ionizers 100 with different electrical outputs from the metal coils 12. For example, the metal coils 12 of any two adjacent rows (or two columns) of ionizers 100 output different electrical properties.

In this way, the oppositely charged ionizers 100 are arranged in one or more rows, so that the purified air can be well purified according to actual needs.

Illustratively, the electric output of the metal coils 12 of any two adjacent ionizers 100 is different. That is, when the metallic coil 12 of one of the ionizers 100 outputs negative electricity, the metallic coil 12 of the adjacent other ionizer 100 outputs positive electricity; alternatively, when the metal coil 12 of one of the ionizers 100 outputs a positive electric charge, the metal coil 12 of the adjacent other ionizer 100 outputs a negative electric charge. The electric power output from the discharge electrode 15 of the ionizer 100 may be opposite to the electric power output from the metallic coil 12 of the ionizer 100.

Set up like this, can purify the air more fully, be favorable to disinfecting with the virus to the bacterium in the air, also be favorable to carrying out subsequent absorption to particulate matter and microorganism in the air simultaneously and eliminate.

As shown in fig. 3, some embodiments of the present invention further provide an air purifying apparatus 400, where the air purifying apparatus 400 includes the ion generating device 200 according to any of the above embodiments, and the collecting device 300.

The collecting device 300 is located at a side of the ion generator 100 of the ion generating device 200 away from the PCB board 20. After the air to be purified passes through the vent holes 21 of the PCB 20 and the ionizer 100 in sequence, the charged and/or large-sized (mass) particles and microorganisms are collected at the collecting device 300, so that the air is purified well.

In some examples, with continued reference to fig. 3, the collection device 300 includes: the outer shell 30 and a plurality of transition plates 40 arranged side by side, wherein the plurality of transition plates 40 are fixed in the outer shell 30; the ion generating device 200 corresponds to the plurality of transition plates 40, that is, air passing through the ion generating device 200 is blown to a gap between adjacent two transition plates 40 of the plurality of transition plates 40.

In some examples, the transition plate 40 is disposed in at least one of the following ways: one of them is that one side of the transition plate 40 is coated with a conductive material, and one end of the transition plate 40 is provided with a power connection terminal which is in electrical contact with the conductive material. Secondly, the other side of the transition plate 40 is coated with an ozone catalyst. Illustratively, only one side of the transition plate 40 is coated with a conductive material or ozone catalyst. As another example, one side of the transition plate 40 is coated with a conductive material, and one end of the side is provided with a power contact terminal in electrical contact with the conductive material; the other side is coated with an ozone catalyst.

Wherein, after being electrified, the conductive material can make the transition plate 40 charged, so as to better adsorb microorganisms and particulate matters in the air after passing through the ion generating device 200.

The ozone catalyst can remove ozone in the air purified by the ion generating device, thereby improving the air purifying effect of the air purifying device 400.

In some examples, the conductive material may be an aqueous conductive material, or may be an oily conductive material. The conductive material comprises one or more of silver paste or graphene and conductive carbon paste.

In some examples, the electrical properties of the inputs are different for two adjacent transition plates 40. That is, one transition plate 40 inputs positive electricity; the other transition plate 40 outputs a negative point. The design can make two adjacent transition plates 40 form a strong electric field between them, so that charged microorganisms and particles can be effectively adsorbed, and the air purification effect is improved.

In some examples, the ozone catalyst may be a manganese dioxide catalyst. The manganese dioxide catalyst can neutralize ozone to form oxygen and water, thereby obtaining better ozone catalysis effect and being beneficial to environmental protection.

In some examples, the transition plate 40 is a corrugated plate body. The wavy plate body can reduce wind resistance, and is beneficial to the collection of microorganisms, particles and the like on the transition plate 40. In addition, compared with two parallel groups of plate bodies with flat surfaces, the probability that microorganisms and particles can contact the transition plate 40 between two parallel groups of wavy plate bodies is greatly increased, so that the adsorption of the microorganisms and the particles is facilitated.

For example, the transition plate 40 may be formed by sequentially splicing together a plurality of S-shaped plates. As another example, the transition plate 40 may be integrally formed.

The transition plate 40 may be an acrylic plate, and the thickness of the transition plate 40 may be set to 0.2mm to 2 mm.

In the manufacturing process of the transition plate 40, firstly, an acrylic plate with flat upper and lower surfaces is selected, then a required strip-shaped conductive film is formed on the surface of the acrylic plate in a screen printing mode, the thickness of the conductive film can be set to be 30-50 micrometers, conductive carbon paste can be adopted as a conductive material, the coated conductive carbon paste is dried into the conductive film through infrared at 50-60 ℃, and then an ozone catalyst (prepared by manganese dioxide and glycerol for example) is coated on the other surface of the acrylic plate.

After the conductive film and the ozone catalyst are coated, the acrylic plate is hot pressed by using a wavy steel mold to form the transition plate 40.

In addition, the transition plate 40 may be subjected to corona treatment before use, so that the molecular structure may be changed, and an anchor chain may be formed on the surface of the transition plate 40 after the corona treatment, thereby enhancing the adhesion of the conductive paint and the ozone catalyst.

Then, the transition plates 40 coated with the conductive materials and the ozone catalyst are stacked in a multi-layer mode, electrodes input between the layers of the transition plates 40 are opposite, and a strong electric field can be formed between the adjacent upper layer and the adjacent lower layer, so that a good particulate matter and microorganism adsorption effect is achieved.

As shown in fig. 4-5, in some examples, outer housing 30 includes: a fixing plate 31 disposed in a hollow shape, and at least one fluid inlet 311 is formed at one side of the fixing plate 31.

A plurality of fluid outlets 313 are provided on one surface side of the fixed plate 31, and the plurality of fluid outlets 313 are each located between adjacent two transition plates 40.

With this arrangement, after the collection device 300 finishes collecting the microorganisms and the particulate matters, fluid (such as air, water, etc.) can be introduced through the fluid inlet 311 located at the side of the fixing plate 31, and the fluid passes through the surface of the transition plate 40 to clean the transition plate 40, so as to remove the particulate matters, the microorganisms, etc. on the surface of the transition plate 40, thereby facilitating subsequent reuse.

In some examples, the fluid may be injected with a high-speed fluid, such as a high-pressure air gun or a high-pressure water gun, which may provide a good cleaning effect for the transition plate 40. In this case, the fluid inlet 311 may employ a flange to increase the stability of the fluid cleaning process.

In some examples, the fixing plate 31 is further provided with a mounting groove 312 for mounting the transition plate 40 at a side of the fluid outlet 313. Illustratively, the mounting groove 312 is wavy, the width of the mounting groove 312 is adapted to the thickness of the transition plate 40, so that the transition plate 40 is aligned with the mounting groove 312 and can be directly clamped into the mounting groove, and the inner walls of the fixing plate 31 located on the two sides of the mounting groove 312 can also form certain constraint on the transition plate 40, thereby preventing the transition plate 40 from loosening up and down in the mounting groove 312.

In some examples, the plurality of fluid outlets 313 are located between peaks of two adjacent mounting slots 312, such that the fluid flowing out of the fluid outlets 313 has a potential energy vertically downward, thereby improving the cleaning effect of the fluid on the transition plate 40.

In some examples, a conductive material is coated on the side of the transition plate 40 where the mounting groove 312 is provided, and at this time, a conductive copper plate portion may be partially inserted into the mounting groove 312 to enhance the overall stability. In addition, the conductive copper plate is electrically connected to the contact terminal at one end of the transition plate 40.

In some examples, a plurality of purge ports 314 are provided on the fixed plate 31 at the opposite side where the fluid inlet 311 is provided. This allows for more efficient cleaning of the microorganisms and particulate matter located within the holding plate 31, thereby facilitating subsequent use. Illustratively, the purge port 314 and the fluid outlet 313 are each a square slot.

In some examples, two fixing plates 31 are provided, and the peripheries of the two fixing plates 31 are connected by fixing posts 32 to form the outer case 30. Of course, the mounting grooves 312 of the two fixing plates 31 face each other, and the mounting of the transition plate 40 can be completed by inserting both ends of the transition plate 40 into the corresponding mounting grooves 312.

In some examples, the fixing plate 31 may be made of polypropylene or ABS plastic, which has high stability and electrical isolation, thereby achieving safety of the collecting device 300.
