According to an embodiment of the first aspect of the present invention, an ion generating assembly is provided, which includes a water tank, a driving member, a conductive member, and a high voltage electrode plate, wherein the water tank is a tank for storing water, and the conductive member is connected to the driving member. Specifically, when the driving member rotates, the conductive member can be driven to move, in addition, one or more transmitting pins are arranged on the conductive member, and a high-voltage polar plate is arranged at a position corresponding to the conductive member, so that in the process of rotating the conductive member, one or more transmitting pins can be right opposite to the high-voltage polar plate, an electric field can be formed between the conductive member and the high-voltage polar plate when the conductive member is electrified, the conductive member can be driven to rotate together through the rotation of the driving member, so that the transmitting pins with water drops sequentially enter the electric field, and nano water ions with air sterilization and odor removal functions are generated.
Specifically, the driving member can drive the conductive member to move, the conductive member is in contact with water in the water tank, one or more emission needles are limited to be opposite to the high-voltage polar plate, the tip of the needle-shaped emission needle can be stained with liquid beads, the liquid beads are induced to be charged under the action of an electric field formed after the high-voltage polar plate is electrified, the surface charges (negative charges) can enable the beads to generate repulsion between internal units, the repulsion is coulomb force, meanwhile, surface tension action also exists between the internal units of the beads to prevent the beads from splitting, when the strength of the electric field is enough to enable coulomb force to be larger than the surface tension, the beads split is called rayleigh splitting.
As will be understood by those skilled in the art, the equilibrium point of water droplet splitting depends on the magnitude of the electric field intensity and the size of the liquid water droplet, that is, the liquid water droplet is not split after being split to a certain size, so as to generate water droplets with stable size, countless water droplets generate a large amount of hydroxyl radicals and other active groups in the water droplets during charging and splitting, under the action of the rotation of the driving member, a plurality of emission needles can sequentially pass through the high-voltage electric field, the water droplets generate Rayleigh splitting, and form stable nanometer water droplets carrying the hydroxyl radicals, so as to generate nanometer water ions with air sterilization and odor removal effects. Countless water mist formed by Rayleigh splitting of water is adsorbed to the positive charge polar plate under the action of an electric field and moves to the position of the opening of the high-voltage polar plate to be further diffused to the air outside the machine to sterilize the space.
In this embodiment, the high voltage plate is further provided with an opening, so that the moving water mist can penetrate through the high voltage plate through the opening and move forward to be emitted into the air. In addition, the conductive member of the present embodiment may be disposed on the wet wheel, and the conductive member is fixed relative to the wet wheel, and the wet wheel has a certain moisture and is rotatable, and the driving member can drive the wet wheel to rotate, and further the driving member can rotate the conductive member. Of course, the driving member may also directly drive the conductive member to move or rotate.
In this scheme, need not additionally to set up refrigerating plant, can comparatively stable production nanometer water ion, the application scope of the product that the subassembly was taken place to the above-mentioned ion is wider.
In addition, the ion generating assembly in the above scheme provided by the invention can also have the following additional technical features:
in the technical scheme, the high-voltage polar plate is provided with the opening, and at least one of the plurality of emission needles is opposite to the opening.
In the technical scheme, at least one of the plurality of emitting pins arranged on the conductive member is opposite to the opening. It can be understood that when one of the two emitting needles is opposite to the opening, at least one other emitting needle is opposite to the opening, that is, in the process that the driving member drives the conductive member to rotate, at any time, the projections of the two or more emitting needles on the high-voltage polar plate are positioned in the opening, so that the generation amount and the action effect of water ions in unit time can be increased.
Among the above-mentioned technical scheme, the opening is the arc hole, and electrically conductive is the conducting ring, and the driving piece can drive the conducting ring and rotate.
In this technical scheme, open-ended shape is the arc, and the opening is the arc hole also, and on this basis, the axis in preferred arc hole and the axis collineation of electrically conductive piece through the axis collineation of restriction arc hole and conducting ring for the opening is along the circumference just to setting up on the removal orbit of transmission needle, thereby can make every transmission needle all can pass through the opening when rotating, makes the aqueous ion of formation outwards discharge comparatively smoothly.
In the technical scheme, the number of the launching needles opposite to the arc-shaped hole is two.
In this technical scheme, set up to two through the quantity with the emission needle that the arc hole is relative, be favorable to improving the effective usable floor area of opening part, increase the formation volume and the effect of water ion in the unit interval.
In the technical scheme, the transmitting needle extends from the outer edge of the conductive piece to the high-voltage polar plate.
In this technical scheme, through the extending direction of restriction transmitting needle for towards the high voltage polar plate, specifically, extend to the high voltage polar plate by the outer fringe of electrically conductive piece, the outer fringe of electrically conductive piece is compared in inside region, and its turning radius is great, can make when downwardly rotating to aquatic, can have more time and aqueous phase contact, and then avoid on the transmitting needle because be stained with water incompletely lead to unable even water film that forms, influence the rayleigh splitting effect.
In addition, it should be noted that, on the basis of the extending direction of the emitting pin, the extending direction of the emitting pin may be directly perpendicular to the surface where the conductive member is located, or may form a certain angle with the surface where the conductive member is located.
Among the above-mentioned technical scheme, be equipped with many hydrophilic structures on the transmission needle, the surface of transmission needle is located to hydrophilic structure.
In the technical scheme, the hydrophilic structure is arranged on the outer surface of the launching needle, so that the water absorption capacity of the launching needle can be effectively improved, and the surface of the launching tip can be uniformly covered by a water film. The hydrophilic treatment can be realized by making nano-scale grooves on the surface of the needle tip or increasing the roughness to improve the hydrophilic capability of the needle tip, and can also be realized by making a hydrophilic coating on the surface of the metal. It will be appreciated that the hydrophilic treatment formed according to the above or similar process allows the emitter pin to form a water film on its surface sufficiently to ensure uniform and reliable rayleigh breakup when passing through water. If the water film is uneven, namely part of metal is exposed on the surface, the exposed metal surface is in preference to water drops to form corona discharge with a high-voltage polar plate, so that normal Rayleigh splitting cannot be performed to form nano water ions.
It is worth to say that the nano-scale grooves can be formed on the surface of the emitting needle or the roughness can be increased to improve the hydrophilic capability of the emitting needle.
In the above technical scheme, the hydrophilic structure is a hydrophilic coating or a hydrophilic scar.
In this technical scheme, through setting up hydrophilic structure into hydrophilic coating or hydrophilic layer, can understand that carries out hydrophilic treatment with the surface of transmission needle, can effectively improve the water-absorbing capacity of transmission needle, ensure simultaneously that the water film evenly covers the transmission tip surface.

In the technical scheme, the diameter range of each transmitting needle is 0.5mm-2 mm; the length of the emitting needle is 8 mm-20 mm.
In the technical scheme, the formation of the electric field can be facilitated by limiting the diameter range and the length of the emitter pin, and particularly, the radius of curvature of the generated water drop can be ensured to be slightly larger than the diameter of the emitter pin by limiting the diameter of the emitter pin to be 0.5mm-2 mm. The conductive member is grounded to form a certain potential difference with the high-voltage polar plate, and in the potential difference, the high-voltage polar plate is a high-potential end, and the conductive member is a low-potential end. And the length of the emission needle is limited, namely the length of the emission needle is 8 mm-20 mm, so that the tip of the emission needle and the high-voltage polar plate form a point-surface electric field, and the subsequent ion separation is more convenient.
In the technical scheme, the ratio of the voltage of the high-voltage polar plate to the minimum distance between the high-voltage polar plate and the transmitting needle is 800V/mm-2000V/mm.
In the technical scheme, after voltage is applied to the high-voltage pole plate, an electric field is formed between the high-voltage pole plate and the conductive piece, and the size of the electric field depends on the size of the positive voltage and the distance between the tip end and the high-voltage pole plate. Although the electric field is a non-uniform electric field, the emission generated by ions is not influenced, the ratio of the voltage to the minimum distance is limited within the range of 800V/mm-2000V/mm, so that the water drops can be stably generated and split, and if the ratio is larger in the range, the induction charging effect is more ideal, and the water drops are more beneficial to generating hydroxyl radicals and acting and space sterilization.
It is understood that the smaller the above ratio is, the larger the rayleigh-split bead diameter is, and the larger the above ratio is, the smaller the rayleigh-split bead diameter is.

In order that the above objects, features and advantages of the embodiments of the present invention can be more clearly understood, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present invention may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.
Some embodiments according to the invention are described below with reference to fig. 1 to 6.
Example one
As shown in fig. 1 to 5, an ion generating assembly 100 according to the present embodiment includes a water tank 101, a driving member 102, a conductive member 104 and a high voltage plate 106, wherein the water tank 101 is a tank for storing water, and the conductive member 104 is disposed at one end of the driving member 102, that is, the conductive member 104 is connected to one end of the driving member 102. Specifically, when the driving member 102 rotates, the conductive member 104 may also rotate together with the driving member 102, and in addition, by providing the plurality of emission pins 1042 on the conductive member 104 and providing the high voltage plate 106 at a position corresponding to the conductive member 104, one or more emission pins 1042 may face the high voltage plate 106 during the rotation of the conductive member 104, so that when the conductive member 104 is powered on, an electric field may be formed between the conductive member 104 and the high voltage plate 106, and the conductive member 104 may be driven to rotate together by the rotation of the driving member 102, so that the emission pins 1042 with water droplets sequentially enter the electric field, thereby generating nano water ions with air sterilization and odor removal effects.
Specifically, the driving member 102 can drive the conductive member 104 to rotate, and the conductive member 104 contacts with water in the water tank 101, and by defining one or more emission pins 1042 to be opposite to the high voltage plate 106, the tip of the emission pin 1042 in a needle shape can be stained with liquid beads, when the high voltage plate 106 is energized to form an electric field, the liquid beads are induced to be charged, and the surface charges (negative charges) can cause the beads to generate repulsion between internal units, which is coulomb force, and simultaneously surface tension exists between the internal units of the beads to prevent the beads from splitting, when the strength of the electric field is enough to cause coulomb force to be greater than the surface tension, the beads split is called rayleigh splitting.
As will be known to those skilled in the art, the equilibrium point of water droplet splitting depends on the magnitude of the electric field intensity and the magnitude of the liquid water droplet, that is, the liquid water droplet is not split after being split to a certain magnitude, so as to generate water droplets with stable magnitude, countless water droplets generate a large amount of hydroxyl radicals and other active groups in the interior during the charging and splitting processes, under the action of the rotation of the driving member 102, a plurality of emission needles can sequentially pass through the high-voltage electric field, the water droplets generate Rayleigh splitting, and form stable nanometer water droplets carrying the hydroxyl radicals, so as to generate nanometer water ions with air sterilization and odor removal effects. Countless water mist formed by Rayleigh splitting of water is adsorbed to the positive charge polar plate under the action of an electric field and moves to the position of the opening of the high-voltage polar plate to be further diffused to the air outside the machine to sterilize the space.
In a specific embodiment, an opening 1062 is further provided on the high voltage plate 106, so that the moving mist can penetrate the high voltage plate 106 through the opening 1062 to continue to move forward and be emitted into the air. In addition, the driving member 102 in this embodiment may be a wet wheel 103, and the wet wheel 103 has a certain amount of moisture and is rotatable, but of course, the driving member 102 may also be other driving structures.
In another embodiment, the high voltage plate 106 is not provided with the opening 1062, and the nano-water ions can diffuse out from the edge of the high voltage plate 106.
In this scheme, need not additionally to set up refrigerating plant, can be comparatively stable production nanometer water ion, the application scope of the product that utilizes above-mentioned ion generation subassembly 100 is wider.
Further, the formation of the electric field may be facilitated by limiting the diameter range and length of the emitter pin 1042, and in particular, by limiting the diameter of the emitter pin 1042 to 0.5mm to 2mm, it may be ensured that the radius of curvature of the generated water droplets is slightly larger than the diameter of the emitter pin 1042. Conductive element 104 is grounded and thus forms a potential difference with high voltage plate 106, where high voltage plate 106 functions as a positive electrode and conductive element 104 functions as a negative electrode. In addition, by limiting the length of the emission needle 1042, i.e. the length of the emission needle 1042 is 8 mm-20 mm, the tip of the emission needle 1042 and the high voltage plate 106 form a point-surface electric field, which is more convenient for the subsequent ion separation.
Upon application of a voltage to the high voltage plate 106, an electric field is formed between the high voltage plate 106 and the conductive member 104, and the magnitude of the electric field depends on the magnitude of the positive voltage and the distance of the tip from the high voltage plate 106. Although the electric field is a non-uniform electric field, the generated emission of ions is not influenced, the ratio of the voltage to the minimum distance is limited to be in the range of 800V/mm-2000V/mm, so that water drops can be stably generated and split, and if the ratio is larger in the range, the effect of induction charge is more ideal, and the water drops are more beneficial to generating hydroxyl radicals and acting on space sterilization.
It is understood that the smaller the above ratio, the larger the rayleigh-split bead size, and the larger the above ratio, the smaller the rayleigh-split bead size.
It is added that water is macroscopically neutral, but microscopically, a large amount of ions in the water carry negative charges and an equal amount of positive charges, water or water drops are characterized in that the water or the water drops are kept neutral in a common environment, the charging mode mainly comprises field charging (namely induction charging) and contact charging, the field charging is realized by applying a strong external electric field to induce the neutral water drops to be charged, one scheme of the electric field is that positive voltage (generally about 2Kv-10 Kv) is applied to a flat electrode to apply negative voltage to a needle electrode, the tip of the needle electrode is provided with stable and continuous liquid water drops, and the curvature radius of the liquid water drops is between 0.5mm and 2 mm.
Example two
As shown in fig. 1 to 5, an ion generating assembly 100 according to the present embodiment includes a water tank 101, a driving member 102, a conductive member 104 and a high voltage plate 106, wherein the water tank 101 is a tank for storing water, and the conductive member 104 is disposed at one end of the driving member 102, that is, the conductive member 104 is connected to one end of the driving member 102. Specifically, when the driving member 102 rotates, the conductive member 104 may also rotate together with the driving member 102, and in addition, by providing the plurality of emission pins 1042 on the conductive member 104 and providing the high voltage plate 106 at a position corresponding to the conductive member 104, one or more emission pins 1042 may face the high voltage plate 106 during the rotation of the conductive member 104, so that when the conductive member 104 is powered on, an electric field may be formed between the conductive member 104 and the high voltage plate 106, and the conductive member 104 may be driven to rotate together by the rotation of the driving member 102, so that the emission pins 1042 with water droplets sequentially enter the electric field, thereby generating nano water ions with air sterilization and odor removal effects.
In a specific embodiment, the opening 1062 is formed on the high voltage plate 106, and at least one of the plurality of emission pins 1042 arranged on the conductive element 104 is opposite to the opening 1062, that is, in the process of driving the conductive element 104 by the driving element 102, at any time, two or more projections of the emission pins 1042 on the high voltage plate 106 are located in the opening 1062, thereby facilitating to increase the generation amount and action effect of water ions in unit time.
Further, the projections of the two emission pins 1042 on the high voltage plate 106 are located in the opening 1062.
Further, the formation of the electric field may be facilitated by limiting the diameter range and length of the emitter pin 1042, and in particular, by limiting the diameter of the emitter pin 1042 to 0.5mm to 2mm, it may be ensured that the radius of curvature of the generated water droplets is slightly larger than the diameter of the emitter pin 1042. The conductive member 104 is grounded to form a potential difference with the high voltage plate 106, in which the high voltage plate 106 is a high potential side and the conductive member 104 is a low potential side. And the length of the emission needle 1042 is limited, namely the length of the emission needle 1042 is 8 mm-20 mm, so that the tip of the emission needle 1042 and the high voltage plate 106 form a point-surface electric field, and the subsequent ion separation is more convenient.
Upon application of a voltage to the high voltage plate 106, an electric field is formed between the high voltage plate 106 and the conductive member 104, and the magnitude of the electric field depends on the magnitude of the positive voltage and the distance of the tip from the high voltage plate 106. Although the electric field is a non-uniform electric field, the generated emission of ions is not influenced, the ratio of the voltage to the minimum distance is limited to be in the range of 800V/mm-2000V/mm, so that water drops can be stably generated and split, and if the ratio is larger in the range, the effect of induction charge is more ideal, and the water drops are more beneficial to generating hydroxyl radicals and acting on space sterilization.
It is understood that the smaller the above ratio, the larger the rayleigh-split bead size, and the larger the above ratio, the smaller the rayleigh-split bead size.

As shown in fig. 1 to 5, an ion generating assembly 100 according to the present embodiment includes a water tank 101, a driving member 102, a conductive member 104 and a high voltage plate 106, wherein the water tank 101 is a tank for storing water, and the conductive member 104 is disposed at one end of the driving member 102, that is, the conductive member 104 is connected to one end of the driving member 102. Specifically, when the driving member 102 rotates, the conductive member 104 may also rotate together with the driving member 102, and in addition, by providing the plurality of emission pins 1042 on the conductive member 104 and providing the high voltage plate 106 at a position corresponding to the conductive member 104, one or more emission pins 1042 may face the high voltage plate 106 during the rotation of the conductive member 104, so that when the conductive member 104 is powered on, an electric field may be formed between the conductive member 104 and the high voltage plate 106, and the conductive member 104 may be driven to rotate together by the rotation of the driving member 102, so that the emission pins 1042 with water droplets sequentially enter the electric field, thereby generating nano water ions with air sterilization and odor removal effects.
The opening 1062 is arc-shaped, that is, the opening 1062 is an arc-shaped hole, on this basis, preferably, the axis of the arc-shaped hole is collinear with the axis of the conductive member, and by limiting the axis of the arc-shaped hole and the axis of the wire guide ring to be collinear, the opening 1062 is arranged on the moving track of the transmitting pins 1042 along the circumferential direction, so that each transmitting pin 1042 can pass through the opening 1062 when rotating, and the formed water ions can be discharged outwards smoothly.
Further, the number of the emission needles opposite to the arc-shaped holes is set to be two, so that the effective use area of the opening is favorably increased, and the generation amount and the action effect of water ions in unit time are increased.
Further, the formation of the electric field may be facilitated by limiting the diameter range and length of the emitter pin 1042, and in particular, by limiting the diameter of the emitter pin 1042 to 0.5mm to 2mm, it may be ensured that the radius of curvature of the generated water droplets is slightly larger than the diameter of the emitter pin 1042. Conductive element 104 is grounded, thereby forming a potential difference with high voltage plate 106, where high voltage plate 106 is the high potential side and conductive element 104 is the low potential side. And the length of the emission needle 1042 is limited, namely the length of the emission needle 1042 is 8 mm-20 mm, so that the tip of the emission needle 1042 and the high voltage plate 106 form a point-surface electric field, and the subsequent ion separation is more convenient.
Upon application of a voltage to the high voltage plate 106, an electric field is formed between the high voltage plate 106 and the conductive member 104, the magnitude of the electric field being determined by the magnitude of the positive voltage and the distance of the tip from the high voltage plate 106. Although the electric field is a non-uniform electric field, the generated emission of ions is not influenced, the ratio of the voltage to the minimum distance is limited to be in the range of 800V/mm-2000V/mm, so that water drops can be stably generated and split, and if the ratio is larger in the range, the effect of induction charge is more ideal, and the water drops are more beneficial to generating hydroxyl radicals and acting on space sterilization.
It is understood that the smaller the above ratio, the larger the rayleigh-split bead size, and the larger the above ratio, the smaller the rayleigh-split bead size.
Example four
As shown in fig. 1 to 5, an ion generating assembly 100 according to the present embodiment includes a water tank 101, a driving member 102, a conductive member 104 and a high voltage plate 106, wherein the water tank 101 is a tank for storing water, and the conductive member 104 is disposed at one end of the driving member 102, that is, the conductive member 104 is connected to one end of the driving member 102. Specifically, when the driving member 102 rotates, the conductive member 104 may also rotate together with the driving member 102, and in addition, by providing the plurality of emission pins 1042 on the conductive member 104 and providing the high voltage plate 106 at a position corresponding to the conductive member 104, one or more emission pins 1042 may face the high voltage plate 106 during the rotation of the conductive member 104, so that when the conductive member 104 is powered on, an electric field may be formed between the conductive member 104 and the high voltage plate 106, and the conductive member 104 may be driven to rotate together by the rotation of the driving member 102, so that the emission pins 1042 with water droplets sequentially enter the electric field, thereby generating nano water ions with air sterilization and odor removal effects.
The extending direction of the emitter pin 1042 is towards the high voltage electrode plate 106, specifically, the outer edge of the conductive element 104 extends towards the high voltage electrode plate 106, and the outer edge of the conductive element 104 has a larger rotating radius than the inner region, so that when the conductive element rotates downwards into water, more time can be provided for contacting with the water, and the influence on the effect caused by the fact that water drops cannot normally split due to incomplete wetting on the emitter pin 1042 is avoided. .
In addition, it should be noted that, on the basis of the extending direction of the emitting needle 1042, the extending direction of the emitting needle 1042 may be directly perpendicular to the surface of the conductive member 104, or may form a certain angle with the surface of the conductive member 104.
Further, the formation of the electric field may be facilitated by limiting the diameter range and length of the emitter pin 1042, and in particular, by limiting the diameter of the emitter pin 1042 to 0.5mm to 2mm, it may be ensured that the radius of curvature of the generated water droplets is slightly larger than the diameter of the emitter pin 1042. Conductive element 104 is grounded, thereby forming a potential difference with high voltage plate 106, where high voltage plate 106 is the high potential side and conductive element 104 is the low potential side. And the length of the emission needle 1042 is limited, namely the length of the emission needle 1042 is 8 mm-20 mm, so that the tip of the emission needle 1042 and the high voltage plate 106 form a point-surface electric field, and the subsequent ion separation is more convenient.
Upon application of a voltage to the high voltage plate 106, an electric field is formed between the high voltage plate 106 and the conductive member 104, and the magnitude of the electric field depends on the magnitude of the positive voltage and the distance of the tip from the high voltage plate 106.

It is understood that the smaller the above ratio, the larger the rayleigh-split bead size, and the larger the above ratio, the smaller the rayleigh-split bead size.
EXAMPLE five
As shown in fig. 1 to 5, an ion generating assembly 100 according to the present embodiment includes a water tank 101, a driving member 102, a conductive member 104 and a high voltage plate 106, wherein the water tank 101 is a tank for storing water, and the conductive member 104 is disposed at one end of the driving member 102, that is, the conductive member 104 is connected to one end of the driving member 102. Specifically, when the driving member 102 rotates, the conductive member 104 may also rotate together with the driving member 102, and in addition, by providing the plurality of emission pins 1042 on the conductive member 104 and providing the high voltage plate 106 at a position corresponding to the conductive member 104, one or more emission pins 1042 may face the high voltage plate 106 during the rotation of the conductive member 104, so that when the conductive member 104 is powered on, an electric field may be formed between the conductive member 104 and the high voltage plate 106, and the conductive member 104 may be driven to rotate together by the rotation of the driving member 102, so that the emission pins 1042 with water droplets sequentially enter the electric field, thereby generating nano water ions with air sterilization and odor removal effects. .
As shown in FIG. 4, by providing the hydrophilic structure 1044 on the outer surface of the emitter pins 1042, the water absorption capability of the emitter pins 1042 can be effectively improved, and at the same time, it is ensured that the water film uniformly covers the surface of the emitter tip. The hydrophilic structure can be realized by making nano-scale grooves on the surface of the needle tip or increasing the roughness to improve the hydrophilic capability of the needle tip, and can also be realized by making a hydrophilic coating on the surface of the metal. It will be appreciated that the hydrophilic structure formed according to the above or similar process allows the emitter pin 1042 to form a water film on its surface sufficiently when passing through water, ensuring uniform and reliable rayleigh breakup. If the water film is uneven, namely part of metal is exposed on the surface, the exposed metal surface is prior to water drops to form corona discharge with the high-voltage polar plate, so that normal Rayleigh splitting cannot be performed to form nano water ions.
It is worth to say that the nano-scale grooves can be formed on the surface of the emitting needle or the roughness can be increased to improve the hydrophilic capability of the emitting needle.
Further, the hydrophilic structure is a hydrophilic coating or a hydrophilic scar. Through setting up hydrophilic structure into hydrophilic coating or hydrophilic layer, can understand, carry out hydrophilic treatment with the surface of launching the needle, can effectively improve the water-absorbing capacity of launching the needle, ensure simultaneously that the water film evenly covers the most advanced surface of transmission.
Further, the formation of the electric field may be facilitated by limiting the diameter range and length of the emitter pin 1042, and in particular, by limiting the diameter of the emitter pin 1042 to 0.5mm to 2mm, it may be ensured that the radius of curvature of the generated water droplets is slightly larger than the diameter of the emitter pin 1042. Conductive element 104 is grounded, thereby forming a potential difference with high voltage plate 106, where high voltage plate 106 is the high potential side and conductive element 104 is the low potential side. And the length of the emission needle 1042 is limited, namely the length of the emission needle 1042 is 8 mm-20 mm, so that the tip of the emission needle 1042 and the high voltage plate 106 form a point-surface electric field, and the subsequent ion separation is more convenient.
Upon application of a voltage to the high voltage plate 106, an electric field is formed between the high voltage plate 106 and the conductive member 104, and the magnitude of the electric field depends on the magnitude of the positive voltage and the distance of the tip from the high voltage plate 106.

It is understood that the smaller the above ratio, the larger the rayleigh-split bead size, and the larger the above ratio, the smaller the rayleigh-split bead size.

As shown in fig. 1 to 5, an ion generating assembly 100 according to the present embodiment includes a water tank 101, a driving member 102, a conductive member 104 and a high voltage plate 106, wherein the water tank 101 is a tank for storing water, and the conductive member 104 is disposed at one end of the driving member 102, that is, the conductive member 104 is connected to one end of the driving member 102. Specifically, when the driving element 102 rotates, the conductive element 104 may also rotate together with the driving element 102, and in addition, by providing a plurality of emitting pins 1042 on the conductive element 104 and providing a high voltage plate 106 at a position corresponding to the conductive element 104, one or more emitting pins 1042 may face the high voltage plate 106 in the process of the rotation of the conductive element 104, so that when the conductive element 104 is powered on, an electric field may be formed between the conductive element 104 and the high voltage plate 106, and by the rotation of the driving element 102, the conductive element 104 may be driven to rotate together, so that the emitting pins 1042 with water droplets sequentially enter the electric field, thereby generating nano water ions with air sterilization and odor removal effects. .
By limiting the plurality of emitting needles 1042 to be uniformly arranged around the axis of the conductive member 104, that is, the emitting needles 1042 are circumferentially arranged in an array form with respect to the axis of the conductive member 104, under the action of the high voltage plate 106 and the conductive member 104, nano water ions can be uniformly and stably output and continuously output outwards, thereby improving the user experience.
Further, the formation of the electric field may be facilitated by limiting the diameter range and length of the emitter pin 1042, and in particular, by limiting the diameter of the emitter pin 1042 to 0.5mm to 2mm, it may be ensured that the radius of curvature of the generated water droplets is slightly larger than the diameter of the emitter pin 1042.

It is understood that the smaller the above ratio, the larger the rayleigh-split bead size, and the larger the above ratio, the smaller the rayleigh-split bead size.
EXAMPLE seven
As shown in fig. 6, the air conditioning apparatus 200 according to the embodiment includes a housing 202 and the ion generating assembly 100 according to any of the above embodiments, wherein the housing 202 is provided with an outlet 2022, the water tank 101 is provided with a receiving cavity 2042, and a portion of the conductive member 104 is disposed in the receiving cavity 2042, so that the emitting needle 1042 on the conductive member 104 can be immersed below the water surface, and on this basis, when the driving member 102 rotates, the emitting needle 1042 can be driven to move out of the receiving cavity 2042 until facing the opening 1062 on the high voltage plate 106, so as to generate nano water ions, and then the nano water ions can be driven to be discharged through the outlet 2022 under the action of the air flow, so as to achieve the effect of humidifying the air.
Further, the air conditioning apparatus 200 includes one of a humidifier, a purifier, and a cooling fan.
It should be noted that, since the present embodiment includes the ion generating assembly 100 in any of the above embodiments, the beneficial effects of any of the above embodiments of the ion generating assembly 100 are not repeated herein.
Furthermore, by arranging a driving member in transmission connection with the ion generating assembly 100, the ion generating assembly 100 can drive the conductive member 102 to rotate, so that the transmitting needle 1042 can be continuously removed from the accommodating cavity 2042, and nano water ions are generated when the transmitting needle is directly opposite to the high-voltage polar plate 106, thereby stably improving the use experience of a user.
The driving member may be a manual driving device or an automatic driving device, such as a motor.
Among them, the air conditioning device 200 may be a humidifier.
Further, the high voltage plate 106 is installed on the main body of the humidifier, and is connected with high voltage positive electricity, the conductive member 104 is made of conductive material and is in a circular structure, the circular ring is installed and fixed on the circular driving member 102, 12 emission needles 1042 are equally distributed on the circumference of the circular ring, the included angle between every two adjacent emission needles 1042 is 30 degrees, the high voltage plate 106 is provided with a circular groove (i.e. an opening 1062) structure, the circle center of the circular groove is overlapped with the circle center of the conductive member 104, the circular groove has a fan-shaped angle of 60 degrees or more as a circular structure, and therefore, no matter the conductive member 104 is located at any position, more than two emission needles 1042 fall into the circular groove. The production and action process of the nano water ions is as follows: the bottom region of the conductive device 104 is immersed in water, that is, located in the accommodating cavity 2042, and with the rotation of the circular ring, the emitting needle 1042 immersed in water floats out of the water surface, and a trace amount of liquid water carried by the water forms a film with a certain thickness to cover the emitting needle 1042, but when the water rotates to an electric field region (that is, a positive electric field region with a circular groove structure), the strong electric field causes the charged surface of the water film to be charged, and the charged water rapidly gathers at the ion emitting tip end under the action of the electric field to form charged water droplets, which are further charged, split and atomized by the electric field.
When the nano water ions continue to rotate, the tip of the emission needle 1042 leaves the electric field, the ion emission process is finished and gradually re-immersed in the water, so that a new cycle is started.
The above processes are repeated and continuous, so that the whole machine can continuously generate stable nanometer water ions.
Furthermore, the number of the emitting pins 1042 may be any number, and a plurality of the emitting pins 1042 may not be distributed into the conductive member 104; the driving member 102 and the conductive member 104 are not in a module, but the conductive member 104 may be a single module, so long as the module can cycle water and emit ions, which falls within the protection scope of this patent; the grounding mode of the conductive device 104 can be varied, and since the general humidifier is filled with tap water, and the tap water has a certain conductivity, the cathode can be connected to any component and any position having the same potential as the water body.
According to the embodiment of the ion generating assembly and the air conditioning equipment, the nano water ions can be stably generated without additionally arranging a refrigerating device, and the application range of a product utilizing the ion generating assembly is wider.
