The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0049] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0050] In existing nano-water ion generators, moisture in the air forms water droplets on the condensing needle 11 under the action of the cooling component and remains attached to the surface of the condensing needle 11. Subsequently, the high-voltage discharge component applies a high voltage to the condensing needle 11, causing the water droplets to ionize under the action of a strong electric field. Some water molecules decompose into positively charged hydrogen ions and negatively charged hydroxyl ions. The charged water molecules and their ionization products constitute nano-water ions and are released from the condensing needle 11 into the air.

[0051] As described above, nano-water ions contain active factors surrounded by water molecules. These ions not only increase air humidity but also remove odors, inhibit the growth of mold and bacteria, and prevent their spread. Due to their extremely small size, these nano-water ions possess exceptionally high suspension and diffusivity in the air. Furthermore, the active factors are encapsulated by water molecules, making them more stable and longer-lasting than active substances existing in free radical form.

[0052] Reference Figures 1-7 This utility model provides a nano water ion generating device, including: a substrate 1, a condensation needle 11, a high-voltage discharge section 2, a voltage boosting section 3, a voltage reducing section 4, and a heat-conducting component 13.

[0053] Reference Figures 4-7 The substrate 1 is provided with a condensing needle 11 and a cooling unit 12 composed of at least one P-type semiconductor and at least one N-type semiconductor. One end of the cooling unit 12 is a cooling end 121 and the other end is a heat dissipation end 122. The cooling end 121 is electrically connected to the condensing needle 11 and is used to cool the condensing needle 11 so that water vapor in the air condenses into water droplets on the condensing needle 11.

[0054] High-voltage discharge section 2 is used to apply high voltage to the condensation needle 11;

[0055] The boost unit 3 and the high-voltage discharge unit 2 are used to provide high-voltage AC power to the high-voltage discharge unit 2;

[0056] The step-down unit 4 is electrically connected to the refrigeration unit 12 and is used to provide low-voltage DC power to the refrigeration unit 12;

[0057] A heat-conducting component 13 is provided at the heat dissipation end 122;

[0058] The substrate 1 is provided with at least one first heat dissipation hole 14 for guiding the cold air generated by the cooling end 121 to flow to the heat conduction element 13.

[0059] In this embodiment, the condenser needle 11 refers to a specially designed needle-like structure made of metal or conductive material. Its main function is to provide a condensation surface, allowing water vapor in the air to undergo a phase change on its surface and condense into water droplets. In this embodiment, the condenser needle 11 is made of a material with high thermal conductivity and corrosion resistance, preferably platinum or stainless steel, to ensure that the condensation effect is not affected by oxidation or corrosion during long-term operation. The shape and structural design of the condenser needle 11 tip have a direct impact on the condensation efficiency. (Refer to...) Figures 4-6 The tip of the condensation needle can be designed as a teardrop-shaped structure, which can increase the stress on the water and improve the condensation efficiency; at the same time, the teardrop-shaped structure can also effectively reduce the noise caused by airflow disturbance.

[0060] In this embodiment, the condenser needle 11 is designed as a teardrop shape. However, this embodiment is not limited to this. The shape of the condenser needle 11 can also be optimized according to different application requirements. For example, different geometric structures such as conical, spherical, and slightly curved surfaces can be used to adapt to different condensation environments and working conditions: a conical needle can provide a more concentrated condensation surface, allowing water vapor to condense quickly and slide off the needle surface, thereby reducing the residence time of water droplets; a spherical needle can increase the condensation rate by increasing the surface area, while reducing condensation resistance caused by water droplet accumulation; a slightly curved needle can optimize the flow path of water droplets, making it easier for condensed water to fall off and preventing long-term adhesion of water droplets from affecting the condensation effect.

[0061] In this embodiment, the substrate 1 can be a ceramic substrate 1, a metal substrate 1, or a polymer composite substrate 1, etc.; among which, a ceramic substrate 1 is preferred. Due to its excellent thermal stability and low coefficient of thermal expansion, the ceramic substrate 1 can maintain structural stability in environments with large temperature changes, avoiding performance degradation caused by thermal expansion and contraction. In addition, the ceramic substrate 1 has good electrical insulation and high voltage resistance, which helps to improve the safety of the water ion generator and reduce the risk of electrical breakdown of the discharge components. At the same time, the corrosion resistance and low moisture absorption of the ceramic substrate 1 ensure that the substrate 1 can maintain stable performance in high humidity environments, thereby extending the service life of the device and improving the overall operational reliability.

[0062] The following embodiments involve the Peltier effect, which is the phenomenon where electrons transition between different materials when an electric current passes through them, resulting in the absorption or release of energy and thus a cooling effect. In this embodiment, the cooling unit 12, composed of at least one P-type semiconductor and at least one N-type semiconductor, is equivalent to a PN junction. The cooling unit 12 utilizes the Peltier effect to reduce the temperature of the condenser needle 11, so that water vapor in the air can condense more effectively on the surface of the condenser needle 11.

[0063] The PN junction in the refrigeration unit 12 has a cooling end 121 and a heat dissipation end 122 at its two ends. The cooling end 121 is electrically connected to the condenser needle 11 and is responsible for directly applying the cooling effect to the condenser needle 11, reducing its surface temperature below the dew point, thereby causing water vapor in the air to condense into water droplets. Temperature control of the cooling end 121 is crucial. If the temperature is too high, water vapor cannot condense effectively, affecting the formation of water droplets. If the temperature is too low, frost may form, affecting normal operation. In order to maintain the stable working state of the cooling end 121, the other end of the refrigeration unit 12, namely the heat dissipation end 122, is responsible for dissipating excess heat to avoid the system temperature from becoming too high and causing a decrease in refrigeration efficiency.

[0064] In this embodiment, the high-voltage discharge unit 2 refers to a component used to apply a high voltage to the condensation needle 11, which ionizes the water droplets condensed on the surface of the condensation needle 11 through high voltage, causing them to decompose and release nano-water ions. The boost unit 3 is used to provide a high-voltage AC power supply to the high-voltage discharge unit 2, increasing the voltage to a level suitable for water droplet ionization based on the input voltage, so as to ensure that the high-voltage discharge unit 2 can operate stably.

[0065] This embodiment also includes a step-down unit 4, whose main function is to be electrically connected to the refrigeration unit 12 and provide a stable low-voltage DC power supply to the refrigeration unit 12. The refrigeration unit 12 uses the Peltier effect and requires low-voltage DC power to drive the condenser needle 11 to reduce its temperature. The step-down unit 4 is used to ensure stable output voltage and prevent abnormal operation or efficiency reduction of the refrigeration unit 12 due to voltage fluctuations.

[0066] In this embodiment, the heat dissipation end 122 is provided with a heat-conducting element 13, the main function of which is to absorb the heat released by the heat dissipation end 122 and transfer the heat to the air through a heat exchange process to maintain a stable cooling effect. The heat-conducting element 13 can be made of materials such as aluminum alloy, copper-based materials, or composite phase change materials.

[0067] In this embodiment, at least one first heat dissipation hole 14 is also provided on the substrate 1 to further optimize the heat dissipation effect. The first heat dissipation hole 14 is located on both sides of the condensation needle 11 and penetrates vertically through the entire substrate 1. When the cooling unit 12 is working, the air around the cooling end 121 is affected by the condensation needle 11 and its temperature drops, forming a cold air layer. Since the cold air has a large density, it naturally flows downward under the action of gravity and enters the area around the heat conductor 13 through the first heat dissipation hole 14 and absorbs the heat accumulated in the heat conductor 13, thereby reducing the temperature of the heat conductor 13 and enhancing the heat exchange efficiency between the heat conductor 13 and the air.

[0068] This utility model embodiment provides a heat-conducting element 13 at the heat dissipation end 122 of the refrigeration unit 12 and a first heat dissipation hole 14 on the substrate 1, so that the cold air generated by the cooling end 121 can be effectively guided to the heat-conducting element 13, thereby achieving efficient heat dissipation in a limited space and avoiding the problem of reduced cooling efficiency caused by limited heat dissipation in traditional water ion generators.

[0069] This embodiment of the invention also utilizes the step-down section 4 to provide a stable low-voltage DC power supply to the refrigeration unit 12, preventing the refrigeration unit 12 from being damaged and ensuring the continuous and efficient operation of the refrigeration unit 12, thereby improving the condensation capacity of the condensing needle 11 and increasing the release efficiency of water ions.

[0070] The reasonable heat dissipation path design of this utility model reduces the reliance on additional heat dissipation components, making this utility model suitable for compact application scenarios such as vehicle-mounted and portable air purifiers, and meeting the needs of miniaturized devices for efficient heat dissipation and stable water ion release.

[0071] Reference Figure 8 Furthermore, the boost section includes an inverter boost circuit 220, which includes a first switching transistor Q1, a five-terminal transformer U2, a voltage multiplier unit 221, a matching resistor unit 222, a fourth resistor R4, a fifth resistor R5, and a seventh capacitor C7.

The neutral terminal of the primary side of the five-terminal transformer U2 is connected to the positive terminal of the second input port J3, the first terminal of the seventh capacitor C7, and the first terminal of the fifth resistor R5. The non-primary side of the five-terminal transformer U2 is connected to the collector of the first switching transistor Q1. The base of the first switching transistor Q1 is connected to the second terminal of the fourth resistor R4. The emitter of the first switching transistor Q1 is connected to the first terminal of the seventh capacitor C7 and the negative terminal of the second input port J3. The same-named and opposite-named terminals of the secondary winding of the five-terminal transformer U2 are connected to the voltage multiplier unit 221. The voltage multiplier unit 221 is connected in series with the matching resistor unit 222. The matching resistor unit 222 is connected to the positive terminal of the second output port J4. The opposite-named terminal of the secondary winding of the five-terminal transformer U2 is also connected to the second terminal of the fifth resistor R5 and the negative terminal of the second output port J4. The first switching transistor Q1 is an NPN transistor.

[0072] The inverter boost circuit 220 of this utility model generates an oscillating current through the seventh capacitor C7, the first switching transistor Q1 and the five-terminal transformer U2, and uses the five-terminal transformer U2 and the voltage multiplier unit 221 to generate a two-stage voltage amplification effect. The output AC voltage can reach 3KV to 5KV. The inverter boost circuit 220 has a simple structure and can be miniaturized.

[0073] Furthermore, the voltage multiplier unit 221 includes a third diode D3, a fourth diode D4, a fifth diode D5, an eighth capacitor C8, a ninth capacitor C9, and a tenth capacitor C10. The anode of the third diode D3 is connected to the secondary opposite terminal of the five-terminal transformer U2 and the first terminal of the tenth capacitor C10. The cathode of the third diode D3 is connected to the anode of the fourth diode D4, the first terminal of the eighth capacitor C8, and the first terminal of the ninth capacitor C9. The cathode of the fourth diode D4 is connected to the anode of the fifth diode D5 and the second terminal of the tenth capacitor C10. The cathode of the fifth diode D5 is connected to the second terminal of the ninth capacitor C9 and the matching resistor unit 222.

[0074] It should be noted that the voltage multiplier unit in this embodiment can achieve a three-fold voltage multiplication through the application of three sets of diodes and capacitors. In other application examples, the number of diodes and capacitors can be increased or decreased to achieve other voltage multiplication ratios.

[0075] In some embodiments, the matching resistor unit 222 includes a sixth resistor R6 and a seventh resistor R7 connected in series. It should be noted that the matching resistor unit in this embodiment is used to adjust the output current and frequency. In other application examples, the number of resistors can also be increased or decreased to achieve other adjustment effects.

[0076] Reference Figure 9 Furthermore, the step-down section includes a step-down circuit 210, which includes a switching module U1, a first diode D1, an inductor L1, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a precision voltage regulator D2, a first capacitor C1, a second capacitor C2, and a fourth capacitor C4. The positive terminal of the first input port J1 is connected to the first terminal of the second resistor R2 and the input pin VIN and enable pin EN of the switching module U1. The switching pin SW of the switching module U1 is connected to the cathode of the first diode D1 and the first terminal of the inductor L1. The first capacitor C1 is connected in parallel between the switching pin SW and the bootstrap pin VBST of the switching module U1. The second terminal is connected to the positive terminal of the first output port J2 and the first terminal of the first resistor R1. The second terminal of the first resistor R1 is connected to the feedback pin VFB of the switching module U1 and the first terminal of the third resistor R3. The second terminal of the third resistor R3 is connected to the second terminal of the second resistor R2 and the cathode and reference terminal of the precision voltage regulator D2. The negative terminal of the first input port J1, the ground pin GND of the switching module U1, the anode of the first diode D1, the anode of the precision voltage regulator D2, and the negative terminal of the first output port J2 are all grounded. The second capacitor C2 is connected in parallel between the positive and negative terminals of the first input port J1. The fourth capacitor C4 and the fourth resistor R4 are both connected in parallel between the positive and negative terminals of the first output port J2.

[0077] In practical implementation, the input voltage connected to the first input port J1 can be 5V or 12V. The switching module U1 can be a synchronous buck voltage regulator chip, such as the TPS564201, or other chips with similar functionality. The precision voltage regulator D2 can be a TL431 precision voltage regulator, or other devices with similar functionality. The buck circuit 210 can provide a regulated DC voltage output as low as 120mV, with an output current of 2-2.5A.

[0078] In some implementations, the step-down circuit 210 further includes a third capacitor C3 connected in parallel between the positive and negative terminals of the first input port J1, which can further filter out input interference and regulate voltage.

[0079] In some implementations, the step-down circuit 210 further includes a fifth capacitor C5 and a sixth capacitor C6 connected in parallel between the positive and negative terminals of the first output port J2, which can further stabilize the voltage.

[0080] Furthermore, it also includes multiple pillars 7, which support the high-voltage discharge section 2 above the substrate 1 to ensure a stable distance between the high-voltage discharge section 2 and the substrate 1, thereby optimizing the discharge environment and improving the uniformity and stability of water ion release.

[0081] Furthermore, the columns 7 are evenly distributed between the high-voltage discharge section 2 and the substrate 1, providing mechanical support while ensuring electrical isolation between the high-voltage discharge section 2 and the substrate 1, preventing unnecessary contact between high-voltage components and other structures.

[0082] It should be noted that, in order to adapt to high-temperature working conditions and ensure long-term reliability, the column 7 is made of high-temperature resistant composite material, which can withstand working temperatures up to 360°C, effectively avoiding structural instability caused by thermal expansion, deformation or deterioration. The column 7 may include materials such as polyimide, polyetheretherketone, epoxy resin, silicon oxide, aluminum oxide, and boron nitride.

[0083] To optimize the functional layout of the device and further improve working efficiency and heat dissipation capacity, this embodiment also includes a water ion generating chamber 6. The water ion generating chamber 6 enables the rational distribution of each core component and achieves efficient heat dissipation and stable operation within a limited space.

[0084] Specifically, refer to Figure 3The water ion generating chamber 6 includes a pressure-reducing cavity 61, a pressure-boosting cavity 62, and a water ion emitting cavity 63. The pressure-reducing cavity 61 is used to house the pressure-reducing part 4, and the pressure-boosting cavity 62 is used to house the pressure-boosting part 3. The pressure-reducing cavity 61 and the pressure-boosting cavity 62 are electromagnetically isolated to effectively prevent electromagnetic interference and ensure the stability of the power supply system. The water ion emitting cavity 63 is used to house the substrate 1 and the high-voltage discharge part 2, which is the area used to emit nano-water ions. In the water ion emitting cavity 63, the condensed water droplets are ionized under the action of the high-voltage electric field to generate nano-water ions.

[0085] In one embodiment, to further optimize the heat dissipation effect, refer to Figure 3 The water ion generating chamber 6 is also equipped with a heat dissipation chamber 64, which is adjacent to the water ion generating chamber 6 and is specifically used for heat exchange of the heat-conducting component 13.

[0086] Furthermore, a second heat dissipation hole 641 is provided in the heat dissipation cavity 64, and a third heat dissipation hole 631 is provided in the water ion emission cavity 63. During the operation of the refrigeration unit 12, the cooling end 121 cools down the condensation needle 11, causing water vapor in the air to condense into tiny water droplets. During this process, the air around the condensation needle 11 is affected by the low temperature and its temperature drops, forming a cold air layer. Due to the higher density of the cold air, it naturally flows downward under the action of gravity and enters the area around the heat-conducting component 13 through the first heat dissipation hole 14. When the cold air absorbs the heat from the heat-conducting component 13, its temperature gradually rises, and some of the air enters the heat dissipation cavity 64. During this process, the air in the heat dissipation cavity 64 exchanges heat with the outside air through the second heat dissipation hole 641, so that the internal heat can be dissipated in time, avoiding the excessive temperature of the heat dissipation cavity 64 from affecting the condensation efficiency of the entire device. At the same time, due to the lower density of the hot air, it naturally flows upward under the action of buoyancy and is discharged through the third heat dissipation hole 631 in the water ion emission cavity 63, thereby realizing a natural convection circulation from the low temperature zone to the high temperature zone.

[0087] In this embodiment, the first heat dissipation hole 14, the second heat dissipation hole 641, the third heat dissipation hole 631, the heat dissipation cavity 64, and the water ion emission cavity 63 together promote the air circulation of the water ion generator, which can effectively remove excess heat inside the device, prevent high temperature accumulation from affecting the semiconductor cooling unit 12, and also accelerate air circulation, allowing more fresh air to enter the condensation area, increasing the water vapor concentration in the air, thereby improving the condensation efficiency.

[0088] In this embodiment, the first heat dissipation hole 14, the second heat dissipation hole 641, and the third heat dissipation hole 631 are used as examples for illustration. However, this embodiment is not limited to this. The shape, number, and arrangement of the first heat dissipation hole 14, the second heat dissipation hole 641, and the third heat dissipation hole 631 can be adjusted according to actual needs to optimize the heat dissipation effect and adapt to different equipment structures; for example, the shape of the heat dissipation holes can be circular, elliptical, rectangular, or honeycomb; the number can be increased or decreased according to the heat load of the equipment; the arrangement can be linear, staggered, or grid-like to optimize the air convection path and improve the overall heat dissipation performance. Therefore, the heat dissipation hole design in this embodiment is not limited to a specific form, but can be flexibly adjusted to adapt to the heat dissipation requirements of different application scenarios.

[0089] In one embodiment, reference is made to... Figure 2 The water ion generating chamber 6 is also equipped with a filter 65 to suppress static electricity and prevent carbon buildup on the metal surface inside the water ion emission chamber 63. The filter 65 includes conductive fibers, a stainless steel mesh, an activated carbon layer, and a polymer antistatic material. The conductive fibers can effectively absorb and disperse static charge, the stainless steel mesh provides mechanical support and conductivity, the activated carbon layer is used to adsorb small particles and organic matter in the air, and the polymer antistatic material further enhances the static electricity suppression effect, ensuring long-term stable operation inside the water ion emission chamber 63.

[0090] In one embodiment, reference is made to... Figures 3-6 The high-voltage discharge section 2 is provided with a water ion emission port 21. The water ion emission port 21 is provided with a plurality of radially extending protrusions 22 around it. The protrusions 22 are evenly distributed around the water ion emission port 21.

[0091] Furthermore, the number of protrusions 22 is five or six. Testing has shown that different numbers of protrusions 22 have different effects on the discharge efficiency and release stability of water ions. When there are six protrusions 22, the discharge positions are evenly distributed circumferentially and the spacing is small, making the release path of water ions more dispersed, providing higher discharge efficiency and helping to increase the overall output of water ions. When there are five protrusions 22, the spacing between the protrusions 22 is relatively large, the discharge path is more concentrated, making the water ion release area more stable, reducing the problem of uneven diffusion caused by changes in discharge position, thereby improving the consistency of water ion release.

[0092] Specifically, the outer edge of the protrusion is an arc structure with an arc angle ranging from 5° to 85°, preferably from 37° to 52°. When the arc angle of the protrusion is less than 37°, the local electric field is too concentrated, resulting in uneven discharge and easy local breakdown. When the arc angle exceeds 52°, the electric field distribution tends to be dispersed, resulting in a decrease in discharge intensity, thereby affecting the overall discharge efficiency.

[0093] In this embodiment, five or six protrusions 22 are used as an example. However, this embodiment is not limited to this. The number, shape, depth, and arrangement of the protrusions 22 can be adjusted according to actual application requirements. As an example, the number of protrusions 22 can be appropriately increased or decreased according to the diffusion requirements of water ions, for example, four, seven, or more. In terms of arrangement, the protrusions 22 can be evenly distributed around the circumference of the water ion emission port 21, or they can be distributed at unequal intervals to adapt to the needs of different air circulation environments. Therefore, the design of this embodiment is not only applicable to a specific number of protrusions 22, but can be flexibly adjusted according to the usage scenario to optimize the release stability and diffusion range of water ions.

[0094] In one embodiment, the high-voltage discharge section 2 is further provided with a wiring hole 23. The high-voltage discharge section 2 is electrically connected to the boosting section 3 through the wiring hole 23. The wiring hole 23 is used to connect to the boosting section 3 by riveting or screw fixing. Compared with the traditional welding connection method, this embodiment provides a wiring hole 23 on the high-voltage discharge section 2, which allows rivets or other fasteners to be installed, thereby avoiding material deformation problems caused by high temperature during welding and ensuring the stability of the discharge section structure.

[0095] In one embodiment, the step-down section 4 and the step-up section 3 are electromagnetically isolated. By providing a partition 66 between the step-down section receiving cavity 61 and the step-up section receiving cavity 62, electromagnetic interference is effectively reduced and system stability is improved.

[0096] In one embodiment, the partition 66 is made of a highly conductive material. When an electromagnetic wave acts on the partition 66, the highly conductive material will generate an induced current on its surface. This induced current can weaken the penetration of the electromagnetic wave, thereby achieving an electromagnetic shielding effect.

[0097] In one embodiment, the material of the separator 66 is preferably copper or tin to provide better conductivity and ensure the stability of the shielding effectiveness.

[0098] In one embodiment, an insulating adhesive, such as an epoxy resin composite material, can be filled between the voltage-reducing cavity 61 and the voltage-boosting cavity 62. This not only enhances the insulation performance of the system and prevents high-voltage breakdown, but also effectively prevents water and dust ingress, improving the system's environmental adaptability. Simultaneously, the filling with insulating adhesive enhances thermal conductivity, optimizes heat dissipation, and further reduces electromagnetic wave penetration, thereby improving the overall electromagnetic shielding capability.

[0099] In one embodiment, a water storage tray 5 is fitted onto the condenser needle 11 and employs a porous structure to optimize the collection and regulation of condensate. The pores of the water storage tray 5 are filled with absorbent or hydrophilic materials, such as highly absorbent polymers, fibrous fabrics, or porous absorbent media, to adsorb and store condensate, achieving dynamic balance regulation of condensate and preventing excessive condensate accumulation from affecting discharge stability or insufficient condensate from reducing water ion release efficiency. Furthermore, the water storage tray 5 ensures the discharge environment is maintained within a suitable humidity range, improving the stability and continuity of the water ion generator.

[0100] Furthermore, the surfaces of the high-voltage discharge section 2, the water storage pan 5, and the condensation needle 11 are coated with a layer. This coating effectively improves the components' resistance to contamination, reduces the adhesion of dust and impurities, ensures long-term stable operation of the equipment, and extends its service life. On the surface of the high-voltage discharge section 2, the coating reduces material loss due to arc discharge and improves discharge uniformity and long-term stability. On the surface of the water storage pan 5, the coating inhibits microbial growth, prevents scale and dirt deposition, and maintains a clean water storage environment. On the surface of the condensation needle 11, the coating reduces water droplet retention, improves the desorption efficiency of condensate, and optimizes the release process of water ions.

[0101] Specifically, the coating may include fluorinated polymers, silica sol gels, aluminum oxide, titanium oxide, and boron nitride.

[0102] Furthermore, the substrate 1 has drainage ports 15 on both sides along its length to drain excess water and prevent water accumulation from affecting the electrolysis performance.
