Description

Technical Field

[0001] This application relates to the field of air purification technology, and in particular to an ion generator, an ion generating device, an air conditioning system, and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, users are increasingly demanding healthier vehicle cabins, and unpleasant odors have become one of the key pain points affecting the driving experience. Ion generators, due to their ability to eliminate odors and purify the air, are widely used in vehicle cabin air treatment scenarios.

[0003] In related technologies, ion generators typically apply a high voltage to a discharge needle to ionize the condensed water on the needle, thereby producing nano-water ions and achieving a purification effect. However, the amount of condensed water on the discharge needle is often small, resulting in a low amount of nano-water ions generated and a poor air purification effect. Summary of the Invention

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In the embodiments of this application, the terms "in some embodiments," "in some examples," or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "in some embodiments," "in some examples," or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "in some embodiments," "in some examples," or "for example" is intended to present the relevant concepts in a specific manner.

[0039] This application provides a vehicle. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of this application. The vehicle 1000 can be a pure electric vehicle 1000, a hybrid electric vehicle 1000, a plug-in hybrid electric vehicle 1000, a range-extended electric vehicle 1000, a gasoline vehicle 1000, etc. The vehicle 1000 can also be a sedan, truck, bus, lorry, trailer, etc. This application does not specifically limit the type of vehicle 1000.

[0040] Vehicle 1000 may include an air conditioning system, wheels 200, and a body 300. Wheels 200 are connected to the body 300 and are used to roll on the ground to propel vehicle 1000. The air conditioning system is located on the body 300 and is used to blow warm or cold air into the vehicle interior and purify the air inside the body 300. In some other embodiments, the air conditioning system may be applied to other air purification devices such as household air purifiers and central air purification systems; this application does not specifically limit this. Wheels 200 include, but are not limited to, conventional wheels and track wheels; this application does not limit the shape of the wheels 200. In some other embodiments, vehicle 1000 may not have wheels 200; for example, when vehicle 1000 is a maglev train, vehicle 1000 may not have wheels. In still other embodiments, vehicle 1000 may not have a body 300. This application uses vehicle 1000 including wheels 200 and body 300 as an example for illustration, which should not be considered a special limitation of this application.

[0041] The air conditioning system may include an ion generator 100, which generates nano-water ions to purify the air inside the vehicle. Please refer to [link / reference]. Figure 2 , Figure 2 for Figure 1 The diagram shows a circuit structure of the ion generator 100 in the vehicle 1000. In some embodiments, the ion generator 100 may include an ion generator 10. The ion generator 10 is used to ionize condensed water to generate nano-water ions, thereby achieving air purification and odor elimination functions.

[0042] Please continue reading. Figure 2 In some embodiments, the ion generating device 100 further includes an input power supply 20, which is connected to the ion generator 10. The input power supply 20 includes one of direct current, alternating current, and pulsed current.

[0043] In this way, the input power supply 20 can be any type of DC, AC, or pulsed power, providing a suitable and stable power supply for the ion generator 10 and meeting the high-voltage requirements for ionizing condensed water to generate nano-water ions. At the same time, the diverse power supply options allow the ion generator 10 to be adapted to different application scenarios.

[0044] For example, in scenarios without fixed AC power supply, such as in-vehicle environments and outdoor camping, the ion generator 10 can be powered directly by DC power supply devices such as in-vehicle batteries, portable power banks, and lithium battery packs, meeting the application scenarios of mobile purification needs such as in-vehicle air purification and air purification in outdoor tents.

[0045] For example, in scenarios with a fixed mains power supply, such as homes, offices, and shopping malls, it can be directly connected to household AC power or industrial AC power to provide continuous and stable power support for air purification in large spaces, meet the purification needs for long periods and high loads, and is suitable for fixed installation application scenarios such as household air purifiers and commercial fresh air systems.

[0046] For another example, in professional scenarios such as precision purification in laboratories and targeted purification in industrial workshops, pulsed electricity can adjust the pulse frequency and amplitude of the electric field strength as needed, thereby achieving precise adjustment of the amount of nano-water ions generated. It can quickly increase the concentration of nano-water ions in a short time to cope with sudden pollution, and can also maintain long-term purification in low-concentration mode, making it suitable for application scenarios with high requirements for purification accuracy and controllability.

[0047] In related technologies, the ion generator 10 requires a 4000V pulse voltage to ionize condensate. A 4000V pulse voltage means an extremely high voltage change rate, generating strong transient electric fields and electromagnetic radiation. This presents the ion generator 10 with two major challenges: insulation design and electromagnetic interference. Specifically, it requires thicker creepage distances and clearances, and the use of higher-grade insulation materials, which increases the cost of structural design. High-frequency, high-voltage pulses are powerful sources of electromagnetic interference, necessitating metallic shielding to pass electromagnetic compatibility certification, further increasing the cost of structural design.

[0048] To resolve the above issues, please continue reading Figure 2 In some embodiments, the ion generator 100 further includes a transformer module 30 electrically connected between the input power supply 20 and the ion generator 10. The transformer module 30 is adapted to boost the voltage of the input power supply 20 to a value greater than or equal to 3000V and less than or equal to 7000V. Specifically, the transformer module 30 can boost the voltage of the input power supply 20 to 3000V, 3500V, 4000V, 4500V, 5000V, 5500V, 6000V, 6500V, or 7000V.

[0049] In this way, the transformer module 30 can boost the output voltage of the input power supply 20 to a minimum of 3000V, ensuring not only the consistency and no attenuation of the nano-water ion generation efficiency throughout the entire product lifecycle, but also reducing electromagnetic radiation intensity, simplifying electromagnetic compatibility design, and lowering the requirements for insulation materials and structures. Therefore, the ion generator 10 of this application utilizes the self-healing characteristics of condensate water and the synergistic effect of DC drive to improve the reliability of the entire generation system, enabling long-term stable operation at the system level.

[0050] In some examples, the input terminal of transformer module 30 can be electrically connected to input power supply 20, and the output terminal of transformer module 30 can be electrically connected to ion generator 10. Transformer module 30 can convert the pulse voltage of input power supply 20 into AC voltage, or boost or buck the DC voltage of input power supply 20, or boost or buck the AC voltage of input power supply 20.

[0051] For example, when the input power supply 20 has a 12V pulse voltage, the transformer module 30 can convert the 12V pulse voltage into a 3000V AC voltage to match the high voltage required by the ion generator 10 to ionize the condensate to generate nano-water ions.

[0052] For another example, when the input power supply 20 has a DC voltage of 12V, the transformer module 30 can boost the 12V DC voltage to a DC voltage of 3000V to match the high voltage required by the ion generator 10 to ionize the condensate to generate nano water ions.

[0053] For another example, when the input power supply 20 has an AC voltage of 12V, the transformer module 30 can boost the 12V AC voltage to an AC voltage of 3000V to match the high voltage required by the ion generator 10 to ionize the condensate to generate nano water ions.

[0054] The ion generator 10 requires a stable high voltage to ionize condensate in order to generate a high concentration of nano-water ions. If AC power is used directly, the voltage will periodically cross zero and reverse with the frequency, causing frequent fluctuations in the electric field strength between the electrodes, which will reduce the ionization efficiency of the condensate.

[0055] To resolve the above issues, please continue reading Figure 2 In some embodiments, the ion generator 100 further includes an AC / DC conversion module 40, which is electrically connected between the transformer module 30 and the ion generator 10, and the input voltage of the AC / DC conversion module 40 is an AC voltage.

[0056] In this way, the AC / DC conversion module 40 can convert the AC power regulated by the transformer module 30 into the DC power required for the operation of the ion generator 10, which can continuously act on the condensate water and meet the stable high-voltage DC electric field requirements for the ion generator 10 to ionize the condensate water, thereby improving the efficiency of condensate water ionization to generate nano water ions.

[0057] In some embodiments, the ion generator 100 further includes a blowing module located on one side of the ion generator 10. The blowing module can actively diffuse the nano-water ions generated in the ion generator 10 into the external space, thereby increasing the diffusion rate of the nano-water ions and thus improving the purification efficiency. It is understood that in other embodiments, the ion generator 100 may not include the blowing module.

[0058] In some examples, the blowing module can be an electric fan to actively deliver air to the ion generator 10.

[0059] In some embodiments, the ion generator 100 further includes a fragrance subsystem, which can provide occupants with a variety of selectable fragrance options, not only eliminating odors but also actively creating a personalized cabin fragrance environment, enhancing driving comfort and emotional experience. It is understood that in other embodiments, the ion generator 100 may not include a fragrance subsystem.

[0060] In related technologies, the ion generator 10 typically applies a high voltage to the discharge needle to ionize the condensate on the needle, thereby generating nano-water ions to achieve a purification effect. However, the amount of condensate adhering to the discharge needle is relatively small, resulting in a low amount of nano-water ions generated and a poor air purification effect.

[0061] To resolve the above issues, please refer to Figure 3 , Figure 3 for Figure 2A schematic diagram of the ion generator 10 in the ion generating device 100 is shown. The ion generator 10 includes a fixing member 11, a storage space, and two electrodes. At least a portion of the storage space is disposed on the fixing member 11, and the storage space is adapted to communicate with the outside world; the two electrodes are arranged opposite to each other, and the two electrodes are adapted to ionize the condensed water in the storage space to generate nano-water ions when a first voltage is applied.

[0062] It is worth noting that "external environment" refers to the outside atmosphere or the target space, which can be the vehicle's cockpit or an indoor space. "Two electrodes set opposite each other" means that the two electrodes are parallel and spaced apart.

[0063] In the ion generator 10 provided in this application embodiment, at least part of the storage space is provided on the fixing member 11. Water molecules in the air entering from the outside can be liquefied into condensate and stored in the storage space, so that when the first voltage is applied to the two electrodes, the condensate is stably and continuously ionized to generate more nano water ions. The nano water ions escape to the outside and can purify the air, resulting in a better air purification effect.

[0064] In some examples, the first voltage can be a DC voltage, an AC voltage, or a pulse voltage. The first voltage can be supplied by the input power supply 20. For example, the first voltage can be a 12V pulse voltage, and the transformer module 30 can convert the 12V pulse voltage to a 3000V AC voltage, while the AC / DC conversion module 40 can convert the 3000V AC voltage to a 3000V DC voltage to match the high voltage required for the electrode ionization of condensate.

[0065] In related technologies, the discharge needle, under high-voltage discharge, will gradually corrode and be consumed due to electron bombardment. This will cause the discharge efficiency to decrease over time, reduce the amount of nano-water ions produced, and eventually require replacement of the component. Furthermore, the discharge needle is very sensitive to dust in the air; contaminants adhering to the tip of the discharge needle will form an insulating layer, inhibiting the discharge and even causing it to "shut down" completely.

[0066] To address the aforementioned issues, in some embodiments, the fixture 11 and at least one electrode enclose a storage space. In this way, when the electrode ionizes the condensate within the storage space, the condensate continuously covers the ionization site of the electrode, thus physically preventing electrode corrosion and achieving a "maintenance-free" design with the same lifespan as the ion generator 10. Furthermore, due to the coverage of condensate within the storage space, contaminants do not adhere to the electrode, avoiding electrode failure due to dust accumulation, improving operational stability in harsh environments, and thereby resulting in higher ionization efficiency of the electrode for condensate.

[0067] In some examples, at least one of the two electrodes is disposed on the fixing member 11. The fixing member 11 can enclose one of the electrodes to form a storage space. The storage space can be completely disposed within the fixing member 11, or it can be partially disposed within the fixing member 11 and partially disposed within the electrode. It is understood that in other examples, the fixing member 11 can enclose both electrodes to form a storage space. In this case, there are two storage spaces, i.e., the storage space is formed by the fixing member 11 and one electrode. The storage space can be completely disposed within the fixing member 11, or it can be partially disposed within the fixing member 11 and partially disposed within the electrode.

[0068] In some embodiments, each electrode includes a power-on terminal 121, and the power-on terminals 121 of the two electrodes are staggered.

[0069] In this way, the staggered layout of the energized terminals 121 of the two electrodes can avoid the problems of wire tangling and interference during wiring, simplify the assembly process, and also provide convenience for subsequent inspection and maintenance.

[0070] It is worth noting that the staggered arrangement means that when one of the two electrodes is a ring structure and the other is a plate structure, the two electrodes are arranged parallel and spaced apart, and the projections of the energized terminals 121 of the two electrodes on a plane parallel to the two electrodes partially overlap or do not overlap at all. For example, the energized terminals 121 of the two electrodes can be located on opposite sides of the fixing member 11.

[0071] In some examples, the electrode also includes a main body 122 connected to one side of the energized terminal 121. The main body 122 and the energized terminal 121 can be an integral structure or separate structures. The main body 122 can be circular, square, hexagonal, triangular, etc. The main body 122 can be a solid circular plate structure, a ring structure, or a needle structure, but is not limited to these.

[0072] In some embodiments, the electrode material includes at least one of stainless steel and nickel-titanium alloy.

[0073] In this way, both stainless steel and nickel-titanium alloys possess excellent corrosion resistance, effectively resisting rust caused by long-term immersion in condensate, maintaining the flatness and structural integrity of the electrode surface, and preventing uneven electric field distribution and decreased ionization efficiency due to electrode corrosion. Furthermore, stainless steel and nickel-titanium alloys also have high mechanical strength and pressure resistance, making them suitable for the high-voltage operating requirements of the electrodes.

[0074] It is understood that in other embodiments, the electrode material may also be metals such as copper, aluminum, aluminum alloy, and iron.

[0075] Please also refer to Figure 3 and Figure 4In some embodiments, the two electrodes include a first electrode 12 and a second electrode 13, and the fixing member 11 includes an isolation portion 112 disposed between the first electrode 12 and the second electrode 13. The isolation portion 112 is provided with a receiving hole 1121, and at least a portion of the second electrode 13 is enclosed with the receiving hole 1121 to form a storage space.

[0076] In this way, by providing a receiving hole 1121 in the isolation section 112, and the receiving hole 1121 enclosing at least a portion of the area of ​​the second electrode 13 to form a storage space, the second electrode 13 can be allowed to hold condensate, ensuring sufficient condensate storage on the surface of the second electrode 13. When a first voltage is applied to the first electrode 12 and the second electrode 13, the condensate held by the second electrode 13 can be continuously ionized to generate a large number of nano-water ions. After the nano-water ions escape to the outside, they can sterilize and improve the air purification effect.

[0077] In some examples, the isolation portion 112 is a structure other than the receiving hole 1121, which can prevent condensation from forming at locations other than the receiving hole 1121. The isolation portion 112 can be a single structure or a combination of multiple structures. For example, when the isolation portion 112 is a combination of multiple structures, the isolation portion 112 includes an annular plate and a circular plate, with the circular plate disposed within the annular structure of the annular plate, and the receiving hole 1121 disposed in the circular plate.

[0078] In some examples, the size and depth of the receiving hole 1121 can be precisely calculated to accommodate a specific volume of condensate. The size of the second electrode 13 can be larger than the size of the receiving hole 1121, such that a portion of the second electrode 13 encloses the receiving hole 1121 to form a storage space. It is understood that in other examples, the size of the second electrode 13 can be equal to the size of the receiving hole 1121, such that the entire area of ​​the second electrode 13 encloses the receiving hole 1121 to form a storage space.

[0079] In some examples, the storage space can be entirely housed within the fixture 11, such that the size of the receiving hole 1121 is the same as the size of the storage space. It is understood that in other examples, the storage space can be partially housed within the fixture 11 and partially within the second electrode 13, with the second electrode 13 having a groove corresponding to the position of the receiving hole 1121. The storage space is composed of the groove and the receiving hole 1121, thus increasing the amount of condensate that can be stored.

[0080] Please also refer to Figure 2 and Figure 4In some embodiments, the diameter of the receiving hole 1121 is D, where 0 mm < D ≤ 5 mm; and / or, the height of the receiving hole 1121 is H, where 0 mm < H ≤ 5 mm; and / or, the electrical clearance between the first electrode 12 and the receiving hole 1121 is L, where 0 mm < L ≤ 5 mm. Specifically, the diameter D of the receiving hole 1121 can be 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 4.9 mm, or 5 mm. The height H of the receiving hole 1121 can be 0.1 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 4.9 mm, or 5 mm. The electrical clearance L between the first electrode 12 and the receiving hole 1121 can be 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 4.9mm, or 5mm.

[0081] It is worth noting that the electrical clearance refers to the shortest straight-line distance between the first electrode 12 and the receiving hole 1121 measured along the air medium.

[0082] In this way, by controlling the diameter of the receiving hole 1121 within the range of 0mm-5mm, the condensate can spread along the hole wall of the receiving hole 1121 away from the second electrode 13 under the drive of capillary force, thereby forming a thin layer of condensate on the hole wall of the receiving hole 1121; when the second electrode 13 is energized, the generated electron flow can penetrate the thin layer of condensate, fully contact the water molecules and break their molecular bonds, causing the water molecules to dissociate into hydrogen ions and hydroxide ions. These ions will combine with water molecules in the air to form nano water ions.

[0083] By controlling the height of the receiving hole 1121 within the range of 0mm-5mm, the condensate in the receiving hole 1121 can rise along the hole wall of the receiving hole 1121 away from the second electrode 13 under the drive of capillary force, and rise to the end of the receiving hole 1121, thereby forming a thin layer of condensate on the hole wall of the receiving hole 1121; when the second electrode 13 is energized, the generated electron flow can penetrate the thin layer of condensate, fully contact the water molecules and break their molecular bonds, causing the water molecules to dissociate into hydrogen ions and hydroxide ions. These ions will combine with water molecules in the air to form nano water ions.

[0084] By controlling the electrical gap between the first electrode 12 and the receiving hole 1121 within the range of 0mm-5mm, a high-voltage electric field with concentrated intensity can be constructed between the first electrode 12 and the receiving hole 1121. This ensures that after the electron flow completes the ionization reaction of water molecules, it can break down the air medium in the electrical gap and form an electric arc. The electric arc then reaches the first electrode 12 along the direction of the electric field, forming a complete electron transmission circuit.

[0085] Furthermore, the electrical gap between the first electrode 12 and the receiving hole 1121 is less than or equal to 3 mm and greater than 0 mm. This ensures that after the electron flow completes the water molecule ionization reaction, it can break down the air medium within the electrical gap and form an electric arc. The electric arc then travels along the electric field direction to the first electrode 12, forming a complete electron transport circuit.

[0086] In some embodiments, the first electrode 12 is a ring electrode or a needle electrode. When the first electrode 12 is a ring electrode, its ring structure can create a uniform ring-shaped electric field with the receiving hole 1121, resulting in a more comprehensive electric field coverage, which is beneficial for the generation of nano-water ions. When the first electrode 12 is a needle electrode, its pointed structure can utilize the tip discharge effect to concentrate the electric field intensity near the first electrode 12 under the same high voltage conditions. This concentrated electric field intensity can enhance the ionization of the condensate layer, increasing the generation of nano-water ions.

[0087] In some examples, the first electrode 12 can be a ring structure, a regular polygonal ring structure (e.g., a hexagonal ring structure), or a needle-shaped electrode (e.g., a T-shaped electrode). Compared with irregularly shaped electrodes, it can produce a more uniform and predictable electric field distribution, which is beneficial to the stability of the discharge.

[0088] In some examples, the annular electrode can be formed in one piece from stainless steel sheet through a stamping process. Its cross-section can be rectangular or circular. The inner and outer edges of the annular electrode are smooth, without complex bends, folds, or irregular shapes. The annular electrode can be electrically connected to the input power supply 20 via a high-voltage wire. Electrodes in related technologies are generally needle-tip arrays or serrated electrodes, often requiring complex precision machining (such as etching, grinding, and multi-point welding), resulting in high costs. The annular electrode of this application is stamped from standard sheet metal, resulting in a simpler structure, shorter process flow, higher material utilization, and better consistency, thereby reducing manufacturing costs.

[0089] In some examples, the first electrode 12 can be a ring-shaped electrode or a needle-shaped electrode, and the second electrode 13 can be a solid plate-shaped electrode. The second electrode 13 can be a thin metal plate with good thermal conductivity and a flat surface. Its surface near the first electrode 12 directly seals the end of the receiving hole 1121 and forms a storage space with the receiving hole 1121. When a first voltage is applied to both electrodes, a high voltage of several thousand volts is applied to the first electrode 12. As a high-voltage electrode, a strong electric field can be established towards the location of the receiving hole 1121, ensuring that the condensate in each area of ​​the receiving hole 1121 is fully ionized to generate a large number of nano-water ions.

[0090] In some embodiments, the geometric center of the first electrode 12 corresponds to the geometric center of the storage space.

[0091] In this way, when the first electrode 12 is subjected to the first voltage, since the geometric center of the first electrode 12 corresponds to the geometric center of the storage space, it ensures that the condensate can stably gather in the area with the strongest electric field (the geometric center of the electrode is directly opposite the position), forming a condensate pool with controllable position and shape. This ensures that the condensate in each area of ​​the storage space is fully ionized, avoiding the problem that the local condensate cannot be effectively ionized due to insufficient electric field strength.

[0092] In some examples, the storage space can be cylindrical, for example, the storage space can be a receiving hole 1121 provided in the fixing member 11. The geometric center of the first electrode 12 corresponds to the geometric center of the storage space, which means that the central axis of the first electrode 12 and the central axis of the receiving hole 1121 coincide, that is, the two are coaxially arranged.

[0093] It should be noted that in practical applications, due to limitations in equipment precision or installation errors, achieving absolute coincidence between the central axis of the first electrode 12 and the central axis of the receiving hole 1121 is difficult. The description of "coincidence" in this application is not an absolute limitation, but rather indicates a structural arrangement where coincidence can be achieved within a preset error range, thus maximizing the technical effect of the defined features and making the corresponding technical solution easy to implement with high feasibility. For example, "coincidence" includes absolute coincidence and approximate coincidence, where the acceptable deviation range for approximate coincidence can be, for example, within 5°.

[0094] In some embodiments, the fastener 11 further includes a side frame portion 113, the side frame portion 113 having a receiving cavity 111 communicating with the outside, the receiving cavity 111 communicating with the storage space.

[0095] In this way, by setting the side frame portion 113 and connecting it with the isolation portion 112, the overall structural strength of the fixing member 11 can be enhanced. At the same time, the receiving cavity 111 is located inside the side frame portion 113, which can transport the generated nano-water ions to the outside. The first electrode 12 is directly set in the side frame portion 113, which can achieve a stable installation of the electrode.

[0096] In some examples, the side frame portion 113 may be connected to one side of the isolation portion 112.

[0097] In some embodiments, the fixing member 11 is provided with a first limiting groove 114, and the first electrode 12 is disposed in the first limiting groove 114.

[0098] In this way, the first limiting groove 114 can accurately limit and fix the first electrode 12, preventing the first electrode 12 from being displaced due to vibration during the operation of the ion generator 100, thereby ensuring that the relative position between the first electrode 12 and the second electrode 13 remains stable.

[0099] In some examples, the first limiting groove 114 may be provided on the side of the side frame portion 113 of the fastener 11 away from the isolation portion 112. In other examples, the first limiting groove 114 may be provided on the side wall of the side frame portion 113, but is not limited thereto.

[0100] In some embodiments, the first limiting groove 114 includes a first partial groove 1141 and a first clearance hole 1142. The first clearance hole 1142 communicates with the first partial groove 1141 and penetrates the side wall of the side frame portion 113. The main body portion 122 of the first electrode 12 is disposed in the first partial groove 1141, and the two have similar shapes, so that the first partial groove 1141 can limit the main body portion 122. The energized terminal 121 of the first electrode 12 is disposed in the first clearance hole 1142, and one end of the energized terminal 121 of the first electrode 12 extends out of the first clearance hole 1142 to the outside, so that the energized terminal 121 of the first electrode 12 can be easily connected to the input power supply 20 through a high-voltage wire.

[0101] In some embodiments, the side frame portion 113 is provided with at least one ventilation hole 115, and the at least one ventilation hole 115 is connected to the receiving cavity 111 and the outside.

[0102] In this way, by providing at least one ventilation hole 115 in the side frame 113 and having the ventilation hole 115 connected to the receiving cavity 111 and the outside, outside air can be guided into the receiving cavity 111, causing the nano water ions generated in the receiving cavity 111 to escape from the ventilation hole 115 into the outside space, thereby purifying the air.

[0103] In some examples, the side frame 113 can be a hexagonal structure, which makes it easier to hold the side frame 113 and prevents slippage. It is understood that in other examples, the side frame 113 can also be a cylindrical structure, but is not limited to this. The shape of the ventilation hole 115 can be rectangular, triangular, circular, hexagonal, etc., but is not limited to this, as long as it can connect the receiving cavity 111 to the outside.

[0104] In some examples, the ventilation holes 115 on the side frame 113 constitute a key connection channel between the discharge area and the external airflow. When discharge occurs, the condensed water is ionized and generates nano-water ions. The external airflow flows through these ventilation holes 115 across the discharge area, which can efficiently "blow away" and carry away the generated nano-water ions, enabling the directional and efficient release of ions.

[0105] In some embodiments, the number of ventilation holes 115 is multiple. In this way, the distributed layout of multiple ventilation holes 115 can achieve uniform airflow, reduce the airflow resistance of a single hole, and ensure stable air pressure around the receiving hole.

[0106] In some embodiments, at least two of the plurality of ventilation holes 115 are arranged opposite to each other.

[0107] In this way, at least two of the multiple ventilation holes 115 in the side frame 113 are arranged opposite to each other. The convective airflow formed by the oppositely arranged ventilation holes 115 can allow outside air to flow in from one side ventilation hole 115, and drive the nano water ions in the receiving cavity 111 to escape from the opposite side ventilation hole 115, thereby improving the flow efficiency and diffusion rate of nano water ions and preventing nano water ions from being locally retained in the receiving cavity 111.

[0108] It is understood that in other embodiments, all of the plurality of ventilation holes 115 are not arranged opposite each other. For example, the plurality of ventilation holes 115 may be arranged in a pentagonal or triangular pattern.

[0109] Please also refer to Figure 4 and Figure 5 In some embodiments, the fixing member 11 is provided with a second limiting groove 1161 communicating with the storage space, and the second electrode 13 is disposed in the second limiting groove 1161. In this way, the second limiting groove 1161 can accurately limit and fix the first electrode 12, avoid the second electrode 13 from being displaced due to vibration during the operation of the ion generator 100, and thus ensure that the relative position between the first electrode 12 and the second electrode 13 remains stable.

[0110] In some examples, the fastener 11 further includes a support portion 116, which can be connected to the side of the isolation portion 112 opposite to the side frame portion 113, and a second limiting groove 1161 can be provided on the side of the support portion 116 opposite to the isolation portion 112. In other examples, the second limiting groove 1161 can be provided on the side wall of the support portion 116. The fastener 11 is made of an insulating material, such as plastic. At least two of the side frame portion 113, the isolation portion 112, and the support portion 116 are integral structures, for example, the isolation portion 112 and the support portion 116 are integral structures, and the side frame portion 113 and the isolation portion 112 are bonded together.

[0111] In some examples, the fixture 11 serves as the structural framework and insulating carrier of the ion generator 10. Its insulating properties ensure that the high voltage of the first electrode 12 does not leak to other components. The receiving hole 1121 on the fixture 11 physically restricts the accumulation pattern and position of condensate, ensuring that condensate forms in a pre-defined area that is relatively fixed relative to the position of the first electrode 12. In this way, a single fixture 11 can simultaneously achieve four major functions: mechanical support, high-voltage insulation, condensate pattern control, and airflow organization. This high level of integration reduces the number of parts and improves assembly accuracy and reliability.

[0112] In some embodiments, the second limiting groove 1161 includes a second partial groove 1161a and a second clearance hole 1161b, the second clearance hole 1161b communicating with the second partial groove 1161a and penetrating through the sidewall of the support portion 116. The main body portion 122 of the second electrode 13 is disposed in the second partial groove 1161a, and the two have similar shapes, so that the second partial groove 1161a can limit the main body portion 122 of the second electrode 13. The energized terminal 121 of the second electrode 13 is disposed in the second clearance hole 1161b, and one end of the energized terminal 121 of the second electrode 13 extends out of the second clearance hole 1161b to the outside, so that the energized terminal 121 of the second electrode 13 can be conveniently connected to the input power supply 20 through a high-voltage wire.

[0113] In some embodiments, the ion generator 10 further includes a cooling component 14, which is thermally connected to at least one electrode.

[0114] In this way, the cooling component 14 is thermally connected to at least one electrode, which can cool the electrode and liquefy water molecules in the air entering from the outside into condensate, which is then stored in the storage space.

[0115] In some examples, when the cold end temperature of the cooling component 14 drops below the dew point due to operation, the cold energy is conducted to the second electrode 13. When the humid air (or water vapor in the ambient air) flowing through the receiving hole 1121 comes into contact with the low-temperature surface of the second electrode 13, the water vapor condenses into water droplets. Under the guidance of gravity, surface tension, and the receiving hole 1121, these water droplets gather at the bottom of the receiving hole 1121, i.e., the surface of the second electrode 13, forming a continuous or intermittent pool of condensate. This condensate has a self-renewal characteristic—old water molecules are consumed or evaporated during the discharge process, and new condensate is constantly replenished, thereby avoiding the oxidation and corrosion problems of metal electrodes caused by long-term discharge in related technologies, extending the service life of the ion generator 10, and maintaining the long-term stability of discharge efficiency. Compared with the scheme of ionizing condensate by discharge at the tip of the discharge needle in related technologies, this application can generate richer and more stable active particles (such as hydroxyl radicals), reduce ozone generation, and has mild and stable discharge characteristics. In addition, during the generation of nano-water ions, some of the fine water mist that does not participate in ionization is carried out by the airflow, which has a slight auxiliary humidification effect on the environment.

[0116] In some embodiments, the cooling component 14 is in thermal contact with at least one electrode, or the cooling component 14 is in thermal contact with at least one electrode through a thermal interface material.

[0117] In this way, the cooling component 14 and at least one electrode are thermally connected by contact or through a thermal interface material. Both thermal connection methods can construct an efficient and stable heat transfer path, which can quickly transfer the cold energy generated by the cooling component 14 to the electrode, so that the water molecules in the receiving cavity 111 are liquefied and stored in the storage space.

[0118] It is worth noting that thermal interface material refers to functional material used to fill the contact gap between the cooling component 14 and the electrode, in order to reduce contact thermal resistance and improve heat transfer efficiency. For example, thermal interface material can be thermal grease, thermal silicone sheet, or thermal gel.

[0119] In some examples, the cooling component 14 may be thermally connected in contact with one electrode or through a thermal interface material. The cooling component 14 may also be thermally connected in contact with one electrode and through a thermal interface material with another electrode. The cooling component 14 may also be thermally connected in contact with two electrodes or through a thermal interface material.

[0120] In some embodiments, the cooling component 14 is disposed on the side of the second electrode 13 opposite to the first electrode 12.

[0121] In this way, the cooling component 14 is located on the side of the second electrode 13 away from the first electrode 12, which enables the cooling component 14 and the second electrode 13 to achieve stable thermal conduction. This allows the cooling energy generated by the cooling component 14 to be quickly conducted to the electrode, so that the water molecules in the receiving cavity 111 are liquefied and stored in the storage space.

[0122] In some examples, the cooling component 14 can be in contact with or close to the second electrode 13, as long as thermal conductivity between the two can be achieved.

[0123] In some embodiments, the cooling assembly 14 includes a cooling element 141, which is adapted to generate cooling energy when a second voltage is applied and conduct it to the second electrode 13.

[0124] In this way, the cooling component 14 includes a cooling element 141, and the cooling element 141 is adapted to generate cold energy when the second voltage is applied and conduct it to the second electrode 13. It can conduct the cold energy generated by the cooling component 14 to the second electrode 13 through active cooling, so that the water molecules in the receiving cavity 111 are liquefied and stored in the storage space, thereby ensuring that the amount of condensate on the electrode surface is sufficient, providing sufficient raw material support for the continuous generation of nano water ions.

[0125] In some examples, the cooling element 141 can be a semiconductor cooling chip or a liquid cooling structure. For example, when the cooling element 141 is a liquid cooling structure, the liquid cooling structure includes a water pump and a liquid cooling pipe. Applying a second voltage to the liquid cooling structure can cause the water pump to draw liquid from the liquid cooling pipe to generate cooling to cool the electrodes, thereby liquefying the water molecules in the receiving cavity 111 and storing them in the storage space.

[0126] In some examples, the second voltage can be direct current (DC) to cause the cooling element 141 to generate cooling when it is supplied. The second voltage can be supplied via input power supply 20. For example, when the cooling element 141 is a thermoelectric cooler, the second voltage is a DC voltage of 12V.

[0127] In some embodiments, the cooling assembly 14 further includes a heat conduction element 142 electrically connected to the cooling element 141, the heat conduction element 142 being disposed between the cooling element 141 and the second electrode 13, and the heat conduction element 142 being electrically isolated from the second electrode 13.

[0128] In this way, by setting the heat conduction element 142, not only can the cooling element 141 conduct the generated cold energy to the second electrode 13 when the second voltage is applied, but a short circuit between the cooling element 141 and the second electrode 13 can also be avoided.

[0129] In some examples, the cooling element 141 can be a bismuth telluride semiconductor, i.e., a standard semiconductor cooling chip (Peltier patch). Specifically, the cooling element 141 consists of a pair of N-type and P-type bismuth telluride semiconductor structures connected in series. One side of the cooling element 141 is the cold end, and the other side is the hot end. The cold end of the cooling element 141 is thermally connected to the second electrode 13. This semiconductor cooling response is fast, and the temperature of the second electrode 13 can be precisely controlled by adjusting the input voltage, thereby controlling the condensate generation rate and indirectly regulating the amount of nano-water ions produced. This is much more flexible and compact than cooling that relies on ambient temperature or complex mechanical compressors.

[0130] In some examples, a portion of the heat conductor 142 is electrically connected to one side of the N-type bismuth telluride semiconductor structure and the P-type bismuth telluride semiconductor structure, respectively, while the other portion of the heat conductor 142 is electrically isolated from the second electrode 13.

[0131] Please also refer to Figure 4 and Figure 6 , Figure 6 for Figure 4 The diagram shows a schematic of the structure of the heat conduction element 142 in the ion generator 10. In some embodiments, the heat conduction element 142 includes a heat conductor 1421 and an insulator 1422. The heat conductor 1421 is electrically connected to the cooling element 141, and the insulator 1422 is disposed between the second electrode 13 and the heat conductor 1421.

[0132] In this way, the heat conductor 1421 can efficiently conduct the cold energy generated by the cooling component 141 to the second electrode 13. At the same time, the insulator 1422 can isolate the current conduction between the second electrode 13 and the heat conductor 1421, thus preventing a short circuit between the heat conductor 1421 and the second electrode 13.

[0133] In some examples, the insulator 1422 may be connected to or in contact with the heat conductor 1421.

[0134] In some examples, the heat conductor 1421 can be a thermally conductive copper block made of high thermal conductivity copper or a copper alloy. One surface of the heat conductor 1421 is flat and used to connect the electrode; the opposite surface is also flat and used to connect to the cooling component 141 via thermally conductive silicone grease. The insulator 1422 can be an insulating coating, which can be applied to the surface of the heat conductor 1421 by spraying. This ensures electrical isolation between the second electrode 13 and its condensate and the cooling component 14, guaranteeing safety.

[0135] Please also refer to Figure 4 and Figure 7 , Figure 7 for Figure 3The diagram shows the ion generator 10 from another angle. In some embodiments, the cooling assembly 14 further includes a conductive portion 143, which is electrically connected to the cooling element 141 and is adapted to be supplied with a second voltage.

[0136] In this way, by providing the conductive part 143, it can be ensured that the cooling element 141 receives the second voltage and stably generates cooling. Furthermore, the provision of the conductive part 143 simplifies the wiring layout of the cooling element 141, allows for flexible placement of the ion generator 10, and improves the convenience of assembly and maintenance.

[0137] In some examples, the conductive portion 143 may be connected to the side of the cooling element 141 facing away from the heat conduction element 142. There are two conductive portions 143, which are electrically connected to the N-type bismuth telluride semiconductor structure and the P-type bismuth telluride semiconductor structure, respectively. The cooling element 141 and the heat conduction element 142 are disposed within the second limiting groove 1161, thus the second limiting groove 1161 provides protection for the cooling element 141 and the heat conduction element 142.

[0138] In some embodiments, the fixing member 11 is provided with a third clearance hole 1161c suitable for communication with the outside, and the conductive part 143 is disposed in the third clearance hole 1161c. In this way, the position of the conductive part 143 can be defined by the third clearance hole 1161c, and the wiring layout of the ion generator 10 can be more flexible. The entire refrigeration structure can be very compact, without complex components such as compressors and refrigerants. It operates quietly, reliably, and has a long service life, making it very suitable for integration into small devices.

[0139] In some examples, the third clearance hole 1161c can be provided on the side of the support portion 116 away from the side frame portion 113, and one end of the conductive portion 143 extends out of the third clearance hole 1161c. The shape of the conductive portion 143 can be L-shaped, straight, etc., but is not limited to this.

[0140] In use, when a direct current flows through the conductive part 143 and then through the cooling element 141, based on the Peltier effect, one side (cold end) of the cooling element absorbs heat, while the other side (hot end) releases heat. The heat absorbed by the cold end originates from the heat conductor 1421 in close contact with it, thereby rapidly reducing its temperature. This low temperature is transferred to the second electrode 13 through the heat conductor 1421, providing the necessary cold source for water vapor condensation.

[0141] The working process of the ion generator 10 in this application is as follows: Step 1: Cooling and Condensation. Specifically, after applying a second voltage to the cooling component 14, the second voltage causes the cooling element 141 to operate through the conductive part 143. The cooling energy is transferred to the second electrode 13 via the heat conductor 1421, causing its surface temperature to drop below the dew point. Water vapor in the air condenses on the surface of the second electrode 13 and collects in the receiving hole 1121 of the fixing member 11, forming a condensate pool.

[0142] Step two, establish an electric field. Specifically, a first voltage is applied to the first electrode 12 and the second electrode 13. A strong electric field is formed between the first electrode 12 and the second electrode 13.

[0143] Step 3: Discharge and Ion Generation. Specifically, when the electric field strength exceeds the breakdown threshold at the air-water interface, corona discharge or glow discharge occurs between the edge of the first electrode 12 and the surface of the condensate. The discharge process ionizes water and oxygen molecules in the air, which then combine with the nano-sized water particles atomized from the condensate to generate a large number of nano-water ions.

[0144] Step four, ion release. Specifically, the preset airflow (driven by the blower module) passes through the discharge area from the ventilation hole 115 on one side of the fixture 11, quickly carrying away the newly generated nano water ions and active free radicals, and releasing them into the target space through the receiving cavity 111 and the ventilation hole 115 on the other side, playing a role in purification, deodorization, sterilization, and moisturization.

[0145] The ion generator 10 of this application, by employing a low-cost, stamped first electrode 12 and self-renewing condensate, minimizes the manufacturing cost of the first electrode 12 while solving the problems of short lifespan and easy aging of traditional electrodes, achieving a balance between high performance and low maintenance costs throughout its entire life cycle. Furthermore, the self-renewing characteristic of the condensate prevents performance degradation, and the modular design facilitates assembly and maintenance. In addition, the discharge occurs within a sealed fixture 11, effectively isolating the high-voltage section and eliminating metal electrode corrosion issues, resulting in pure ion clusters. The semiconductor cooling element 141 requires no refrigerant, making it more environmentally friendly. Moreover, by intelligently controlling the power of the semiconductor cooling element 141 and the parameters of the input power supply 20, the ion yield and ion cluster size can be flexibly adjusted, achieving intelligent scenario adaptation.

[0146] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0147] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
