Description

Technical Field

[0001] This invention relates to the field of atomization, and more specifically, to an electrostatic atomization system. Background Technology

[0002] Existing electronic atomization devices primarily use heating elements to atomize solutions at temperatures around 300°C. Solutions atomized using this method undergo a series of chemical reactions at high temperatures, potentially leading to the formation of harmful substances such as aldehydes and ketones. Furthermore, the atomized aerosols produced by existing electronic atomization devices have a particle size of approximately 1 micrometer, making it impossible to control the aerosol particle size over a wide range.

[0003] Electrostatic atomization technology can effectively solve the above problems. Existing mature electrostatic atomization technologies are mainly used in mass spectrometry, pesticide spraying, and environmental disinfection. In mass spectrometry applications, although the atomized particle size meets the standard (<2µm), the flow rate is very small, only one-tenth of the target flow rate of electronic atomization devices (such as e-cigarettes), which cannot meet the demand for large atomization volumes. In pesticide spraying and environmental disinfection applications, although the flow rate is large, the atomized particle size is too large (tens of micrometers). Excessively large aerosol particle size causes most aerosol particles to deposit in the mouth and throat, preventing them from entering the lungs. In summary, existing electrostatic atomization technologies either have insufficient atomization flow rate or produce aerosol particles with excessively large sizes. Summary of the Invention

[0039] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments are now described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the invention. However, the invention can be practiced in many ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Figure 1 An electrostatic atomization system 100 according to a first embodiment of the present invention is shown. The electrostatic atomization system 100 may include a first nozzle module 61, a first storage tank 31 for storing a first solution 41 and supplying the first solution 41 to the first nozzle module 61, a first high-voltage generating module 51 for applying a first high voltage to the first solution 41, a second nozzle module 62, a second storage tank 32 for storing a second solution 42 and supplying the second solution 42 to the second nozzle module 62, and a second high-voltage generating module 52 for applying a second high voltage to the second solution 42.

[0041] This electrostatic atomization system 100 can be applied in fields such as medical treatment, beauty, and electronic cigarettes. The first solution 41 and the second solution 42 are solutions capable of electrostatic atomization. The components of the first solution 41 and the second solution 42 can be the same or different. To facilitate electrostatic atomization, the first solution 41 and the second solution 42 need to possess certain physical properties, such as a high viscosity (e.g., viscosity less than 400 cp), and certain resistivity, dielectric constant, and surface tension. In some embodiments, the resistivity of the first solution 41 and the second solution 42 is greater than 200 ohm-m, and further, greater than 250 ohm-m. The dielectric constant of the first solution 41 and the second solution 42 is less than 65, and further, less than 45. The viscosity of the first solution 41 and the second solution 42 is less than 100 cp, and further, less than 50 cp. The surface tension of the first solution 41 and the second solution 42 can be 15–50 dynes / cm, and further, 20–35 dynes / cm.

[0042] The polarity of the first high-voltage electricity applied by the first high-voltage generating module 51 is opposite to the polarity of the second high-voltage electricity applied by the second high-voltage generating module 52. Taking the first high-voltage electricity as positive and the second high-voltage electricity as negative as an example, the first high-voltage generating module 51 applies a positive high-voltage electricity to the first solution 41, making the first solution 41 positively charged. The first nozzle module 61 electrostatically atomizes the positively charged first solution 41 and sprays it out in the form of a positive spray. The second high-voltage generating module 52 applies a negative high-voltage electricity to the second solution 42, making the second solution 42 negatively charged. The second nozzle module 62 electrostatically atomizes the negatively charged second solution 42 and sprays it out in the form of a negative spray. The positively charged positive spray and the negatively charged negative spray are mixed and neutralized after being offset at a certain angle to form a mixed spray without charge, which is conducive to entering the lungs and avoids a large amount of charged aerosols depositing in the mouth and throat. Alternatively, depending on the application scenario, the mixed spray generated after offsetting the positively charged positive spray and the negatively charged negative spray can be made charged to improve the adsorption rate. This method is often used in the medical or beauty fields. Understandably, in other embodiments, the first high voltage may be a negative high voltage and the second high voltage may be a positive high voltage.

[0043] This electrostatic atomization system 100, through positive and negative spray counter-current, significantly increases the atomization volume, solving the problem of electrostatically atomizing solutions even at high flow rates (e.g., ten times higher than existing technologies), with adjustable aerosol particle size. Specifically, the particle size of the generated aerosol (e.g., from a few micrometers to tens of micrometers) can be controlled by adjusting parameters such as voltage, electrode spacing, nozzle orifice size and number, flow rate, and solution conductivity and surface tension. Furthermore, electrostatic atomization operates at room temperature, greatly reducing the generation of harmful substances. Finally, compared to traditional electronic atomization technologies (ceramic and cotton wicks, etc.), electrostatic atomization uses only 50% of the power required to atomize the same mass of solution, significantly reducing energy consumption.

[0044] The first high-pressure generating module 51 can be directly connected to the first solution 41; alternatively, the first high-pressure generating module 51 can also be indirectly connected to the first solution 41. For example, the first high-pressure generating module 51 can be electrically connected to the first storage tank 31 and / or the first nozzle module 61, thereby energizing the first solution 41 within the first storage tank 31 and / or the first nozzle module 61. Similarly, the second high-pressure generating module 52 can be directly connected to the second solution 42; alternatively, the second high-pressure generating module 52 can also be indirectly connected to the second solution 42. For example, the second high-pressure generating module 52 can be electrically connected to the second storage tank 32 and / or the second nozzle module 62, thereby energizing the second solution 42 within the second storage tank 32 and / or the second nozzle module 62.

[0045] The electrostatic atomization system 100 also includes a nozzle 70 for outputting aerosol. The aerosol generated after atomization by the electrostatic atomization system 100 can be actively carried out by airflow, for example, by providing airflow through a blower. Alternatively, the aerosol generated after atomization by the electrostatic atomization system 100 can also be carried out by the user's suction. Specifically, in this embodiment, the electrostatic atomization system 100 includes at least one air inlet 81. When the user suctions through the nozzle 70, outside air enters through the at least one air inlet 81, flows through the first nozzle module 61 and the second nozzle module 62, and carries the aerosol out of the nozzle 70. It can be understood that the electrostatic atomization system 100 can also adopt a mode where part of the aerosol is actively carried out by airflow and part is carried out by the user's suction. For example, when the blower is activated to actively provide airflow, the user simultaneously suctions through the nozzle 70.

[0046] In some embodiments, the electrostatic atomization system 100 may further include a first booster pump 21 and a second booster pump 22. The first booster pump 21 is connected to a first storage tank 31 and is used to apply pressure to the first storage tank 31 to force the first solution 41 in the first storage tank 31 to be ejected from the first nozzle module 61. The second booster pump 22 is connected to a second storage tank 32 and is used to apply pressure to the second storage tank 32 to force the second solution 42 in the second storage tank 32 to be ejected from the second nozzle module 62. The first booster pump 21 and the second booster pump 22 are typically miniature booster pumps, which is beneficial for the miniaturization requirements of the electrostatic atomization system 100.

[0047] Furthermore, the electrostatic atomization system 100 also includes a first voltage controller 11 and a second voltage controller 12. The first voltage controller 11 and the second voltage controller 12 are respectively connected to the first booster pump 21 and the second booster pump 22 to control their operation. The first voltage controller 11 and the second voltage controller 12 can control the compression volume of the first liquid storage tank 31 and the second liquid storage tank 32 by controlling the first booster pump 21 and the second booster pump 22, thereby controlling the mass of the first solution 41 and the second solution 42 ejected, achieving quantitative atomization. In addition, after a single atomization cycle, some solution will remain in the first nozzle module 61 and the second nozzle module 62. As the solvent in the solution evaporates, the solute may clog the nozzles. Therefore, after atomization, the first voltage controller 11 and the second voltage controller 12 can control the first booster pump 21 and the second booster pump 22 to move in reverse, creating a negative pressure in the first liquid storage tank 31 and the second liquid storage tank 32 to draw back the solution from the nozzles.

[0048] In some embodiments, the electrostatic atomization system 100 further includes a housing 80 for housing components such as a first liquid storage tank 31, a second liquid storage tank 32, a first booster pump 21, a second booster pump 22, a first nozzle module 61, a second nozzle module 62, a first high-pressure generating module 51, a second high-pressure generating module 52, and an air supply device. A suction nozzle 70 is disposed on one side of the housing 80, and at least one air inlet 81 is disposed on at least one side wall of the housing 80. In this embodiment, there are multiple air inlets 81, disposed on a side wall of the housing 80 opposite to the suction nozzle 70. It is understood that the arrangement of the air inlets 81 is not limited to the above-described manner. For example, there may be only one air inlet 81, or multiple air inlets 81 distributed on different sides of the housing 80, as long as the incoming airflow from the air inlets 81 can better carry the aerosol out of the suction nozzle 70.

[0049] In addition, in some embodiments, the electrostatic atomization system 100 may be equipped with other auxiliary devices as needed, such as a stirrer for stirring the solution in the first liquid storage tank 31 and / or the second liquid storage tank 32, a pressure sensor for detecting the gas pressure in the first liquid storage tank 31 and / or the second liquid storage tank 32, a cooler for cooling the solution in the first liquid storage tank 31 and / or the second liquid storage tank 32, and so on.

[0050] like Figure 2-3 As shown, the first nozzle module 61 includes a plurality of first nozzles 610, and the second nozzle module 62 includes a plurality of second nozzles 620. In this embodiment, the plurality of first nozzles 610 and the plurality of second nozzles 620 are arranged in a linear fashion, and the plurality of first nozzles 610 and the plurality of second nozzles 620 are arranged in a staggered manner. This arrangement can maximize the use of space, achieving the effect of both meeting the atomization volume requirements and saving space. Furthermore, the axial direction of the first nozzles 610 is set at a certain angle to the axial direction of the second nozzles 620, so that the spray from the plurality of first nozzles 610 can be mixed with the spray from the plurality of second nozzles 620.

[0051] Specifically, in this embodiment, a plurality of first nozzles 610 are evenly spaced along a straight line on the middle of the side wall of the first liquid storage tank 31, and a plurality of second nozzles 620 are evenly spaced along a straight line on the middle of the side wall of the second liquid storage tank 32, with the plurality of first nozzles 610 and the plurality of second nozzles 620 alternating one-to-one. In other embodiments, the plurality of first nozzles 610 and the plurality of second nozzles 620 may also be alternating in other ways, such as alternating in pairs.

[0052] Furthermore, the two first nozzles 610 located at the two ends of the straight line are blocked and do not discharge liquid, as are the two second nozzles 620 located at the two ends of the straight line. In addition, the lengths of the multiple first nozzles 610 are different; specifically, the length of the multiple first nozzles 610 gradually decreases from the center to both ends, that is, the first nozzle 610 located in the middle of the straight line is longer, and the first nozzles 610 located at both ends of the straight line are shorter. Similarly, the lengths of the multiple second nozzles 620 are different; specifically, the length of the multiple second nozzles 620 gradually decreases from the center to both ends, that is, the second nozzle 620 located in the middle of the straight line is longer, and the second nozzles 620 located at both ends of the straight line are shorter. This arrangement ensures a uniform electric field and guarantees stable spraying from the first nozzle module 61 and the second nozzle module 62. In other embodiments, the multiple first nozzles 610 and the multiple second nozzles 620 may also have the same length.

[0053] In some embodiments, both the first nozzle 610 and the second nozzle 620 can be metal needles. In other embodiments, the first nozzle 610 and the second nozzle 620 can also be made of non-metallic materials, such as insulating, hydrophobic, and oleophobic materials.

[0054] Figure 4 A schematic diagram of the arrangement of the first nozzle module 61 and the second nozzle module 62 in an alternative embodiment of the present invention is shown. In this embodiment, the plurality of first nozzles 610 and the plurality of second nozzles 620 are also arranged in a staggered, interleaved manner. Figure 3 Unlike the illustrated embodiment, in this embodiment, the plurality of first nozzles 610 and the plurality of second nozzles 620 are arranged in an alternating pairwise arrangement. Specifically, every two first nozzles 610 form a group of first nozzles 610, and every two second nozzles 620 form a group of second nozzles 620, with each group of first nozzles 610 and each group of second nozzles 620 arranged alternately. Furthermore, in this embodiment, the two first nozzles 610 in each group of first nozzles 610 have the same length, and the length of the multiple groups of first nozzles 610 gradually decreases from the center to both ends; similarly, the two second nozzles 620 in each group of second nozzles 620 have the same length, and the length of the multiple groups of second nozzles 620 gradually decreases from the center to both ends.

[0055] Understandably, in other embodiments, the structures of the first nozzle module 61 and the second nozzle module 62 include, but are not limited to, the structural designs described above. For example, each group of first nozzles 610 and each group of second nozzles 620 may also have different lengths. Furthermore, each group of first nozzles 610 and each group of second nozzles 620 may each consist of three or more nozzles.

[0056] Figure 5-6The electrostatic atomization system 100 of the second embodiment of the present invention is shown. Its main difference from the first embodiment is that the first nozzle module 61 and the second nozzle module 62 in this embodiment are arranged in a circular array. In addition, the electrostatic atomization system 100 in this embodiment also includes a counter electrode 90 disposed between the first nozzle module 61 and the second nozzle module 62.

[0057] Specifically, the first nozzles 610 of the first nozzle module 61 are arranged in a circular array uniformly on one side wall of the first liquid storage tank 31, and the second nozzles 620 of the second nozzle module 62 are arranged in a circular array uniformly on one side wall of the second liquid storage tank 32, with each first nozzle 610 and each second nozzle 620 positioned opposite each other. Furthermore, the lengths of the first nozzles 610 and the second nozzles 620 are identical. This circular array arrangement ensures that each nozzle on the circumference can stably produce mist, reducing interference between nozzles due to the electric field.

[0058] A counter electrode 90 is positioned between the first nozzle module 61 and the second nozzle module 62, with the center lines of the counter electrode 90, the first nozzle module 61, and the second nozzle module 62 aligned. This counter electrode 90 is typically a ground electrode, its function being to ensure a uniform and stable electric field, resulting in more stable spraying. A first high-voltage generating module 51 is configured to apply high voltage between the first nozzle module 61 and the counter electrode 90, thereby creating a high-voltage electric field that draws the solution from the first nozzle module 61 toward the counter electrode 90. A second high-voltage generating module 52 is configured to apply high voltage between the second nozzle module 62 and the counter electrode 90, thereby creating a high-voltage electric field that draws the solution from the second nozzle module 62 toward the counter electrode 90. The counter electrode 90 has a channel 91 through which the spray from the first nozzle module 61 and the second nozzle module 62 can pass. In this embodiment, the counter electrode 90 is annular, and the inner diameter of the counter electrode 90 is larger than the spray diameter of the first nozzle module 61 and the second nozzle module 62, so that the spray sprayed by the first nozzle module 61 and the spray sprayed by the second nozzle module 62 can enter the counter electrode 90 for counter-mixing.

[0059] In this embodiment, the electrostatic atomization system 100 can also atomize solutions with high viscosity at room temperature (e.g., 25°C) and high flow rate (e.g., 0.15 ml / min) by means of positive and negative spray counteraction.

[0060] Figure 7A partial structural schematic diagram of the electrostatic atomization system 100 in the third embodiment of the present invention is shown. Unlike the second embodiment described above, in this embodiment, the first nozzle module 61 and the second nozzle module 62 are arranged in a linear array. The axial direction of the first nozzle module 61 can be parallel to the axial direction of the second nozzle module 62, or it can be at an angle to the axial direction of the second nozzle module 62.

[0061] Specifically, a plurality of first nozzles 610 of the first nozzle module 61 are arranged at intervals along a straight line on one side wall of the first liquid storage tank 31, and a plurality of second nozzles 620 of the second nozzle module 62 are arranged at intervals along a straight line on one side wall of the second liquid storage tank 32. The plurality of first nozzles 610 are respectively positioned opposite to the plurality of second nozzles 620. Specifically, when the axial direction of the first nozzle module 61 is parallel to the axial direction of the second nozzle module 62, the central axis of one first nozzle 610 and the central axis of the corresponding second nozzle 620 are on a straight line; when the axial direction of the first nozzle module 61 and the axial direction of the second nozzle module 62 form an angle, the extension line of the central axis of one first nozzle 610 intersects the extension line of the central axis of the corresponding second nozzle 620.

[0062] Furthermore, in this embodiment, the lengths of the multiple first nozzles 610 gradually decrease from the center to both ends; that is, the first nozzle 610 located in the middle of the straight line is longer, and the first nozzles 610 located at both ends of the straight line are shorter. Similarly, the lengths of the multiple second nozzles 620 gradually decrease from the center to both ends; that is, the second nozzle 620 located in the middle of the straight line is longer, and the second nozzles 620 located at both ends of the straight line are shorter. This arrangement helps improve the uniformity of the electric field, ensuring stable spraying from the first nozzle module 61 and the second nozzle module 62. Further, the two first nozzles 610 located at the very ends of the straight line are blocked and do not dispense liquid, and the two second nozzles 620 located at the very ends of the straight line are also blocked and do not dispense liquid, which helps ensure stable spraying from the other nozzles.

[0063] The counter electrode 90 is positioned between the first nozzle module 61 and the second nozzle module 62 to ensure a uniform and stable electric field, thereby improving spray stability. The counter electrode 90 in this embodiment can be, but is not limited to, other types. Figure 8 or Figure 9 The sheet-like structure shown. In Figure 8 In this configuration, there are multiple channels 91, and the number of channels 91 is the same as the number of first nozzles 610 and second nozzles 620. These multiple channels 91 are respectively configured to correspond one-to-one with the multiple first nozzles 610 and the multiple second nozzles 620. Figure 9In this embodiment, there is one channel 91, which is an elongated slit shape. Its length direction is parallel to the arrangement direction of the plurality of first nozzles 610 and the plurality of second nozzles 620, so that the sprays emitted by the plurality of first nozzles 610 and the plurality of second nozzles 620 can both pass through this single channel 91. It is understood that in other embodiments, the number of channels 91 is not limited to the two implementation methods described above. For example, one channel 91 may also be provided corresponding to two or more first nozzles 610 (or second nozzles 620).

[0064] Figure 10 A partial structural schematic diagram of the electrostatic atomization system 100 according to the fourth embodiment of the present invention is shown. The main difference between this embodiment and the third embodiment is that the multiple first nozzles 610 and the multiple second nozzles 620 in this embodiment have the same length. The opposing electrode 90 in this embodiment may also be, but is not limited to, other types. Figure 8 or Figure 9 The structure shown.

[0065] Understandably, in the second, third and fourth embodiments described above, the arrangement of the first nozzle module 61 and the second nozzle module 62 will occupy a large space inside the electrostatic atomization system 100, and is therefore suitable for situations where the electrostatic atomization system 100 has sufficient space.

[0066] It should be noted that the structures of the first nozzle module 61, the second nozzle module 62, the opposing electrode 90, etc. of the present invention include, but are not limited to, the above-mentioned structural designs. For example, the first nozzle module 61 and the second nozzle module 62 may each include only one nozzle, or the first nozzle module 61 and the second nozzle module 62 may be arranged in other array shapes.

[0067] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0068] The above embodiments merely illustrate specific implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
