[0002] In the field of modern air purification and humidification technology, water ion generators are widely used in household appliances, car air purifiers and medical care equipment. Water ion generators can effectively reduce suspended particulate matter in the air and degrade pathogens and harmful gases by releasing charged water ions in the air. Compared with traditional filter-type purification technology, water ion generation technology can provide a more lasting and uniform air purification effect without causing secondary pollution.

[0003] However, existing water ion generating devices usually use large heat sinks or fans for auxiliary heat dissipation, but these solutions usually require a large installation space and are difficult to apply to miniaturized equipment. For example, in compact application scenarios such as vehicle-mounted and portable air purifiers, the compact internal structure cannot accommodate large heat dissipation components, which limits the heat dissipation efficiency, further reduces the cooling effect of the device, and affects the continuous and stable release of water ions.

[0046] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0047] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can 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 invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In the existing nano water ion generating device, moisture in the air forms water droplets on the condensation needle 11 under the action of the cooling component and remains attached to the surface of the condensation needle 11. Subsequently, the high-voltage discharge component applies a high voltage to the condensation needle 11, so that the water droplets are ionized under the action of the strong electric field, and some water molecules are decomposed into positively charged hydrogen ions and negatively charged hydroxyl ions. The charged water molecules and their ionization products form nano water ions and are released from the condensation needle 11 into the air.

[0051] As mentioned above, the nano water ions contain active factors surrounded by water molecules, which can not only increase the humidity of the air, but also remove odors, inhibit the growth of mold and bacteria, and prevent their spread; the nano water ions are extremely small in size, so they have extremely high suspension and diffusion capabilities in the air. In addition, the active factors are wrapped by water molecules, making them more stable than active substances in the form of free radicals, and have a longer retention time.

[0052] Reference Figure 1-7 The embodiment of the present invention provides a nano water ion generating device, including: a substrate 1, a condensation needle 11, a high-voltage discharge part 2, a boost part 3, a buck part 4 and a heat conductor 13.

[0053] Reference Figure 4-7 A condensation needle 11 and a refrigeration unit 12 composed of at least one P-type semiconductor and at least one N-type semiconductor are provided on the substrate 1. One end of the refrigeration 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 condensation needle 11. The cooling end 121 is used to cool the condensation needle 11 so that water vapor in the air condenses into water droplets on the condensation needle 11.

[0054] A high voltage discharge unit 2, used for applying a high voltage to the condensation needle 11;

[0055] The booster unit 3 and the high-voltage discharge unit 2 are used to provide a high-voltage AC power supply 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 a low-voltage DC power supply to the refrigeration unit 12;

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

[0058] At least one first heat dissipation hole 14 is disposed on the substrate 1 , and is used to guide the cold air generated by the cooling end 121 to flow toward the heat transfer element 13 .

[0059] In this embodiment, the condensation needle 11 refers to a specially designed needle-shaped structure of metal or conductive material, whose main function is to provide a condensation surface so that water vapor in the air undergoes a phase change on its surface and condenses to form water droplets. The condensation needle 11 in this embodiment is made of a material with high thermal conductivity and corrosion resistance, preferably platinum or stainless steel, to ensure that the condensation effect will not be affected by oxidation or corrosion during long-term operation; the shape and structural design of the needle head of the condensation needle 11 have a direct impact on the condensation efficiency, refer to Figure 4-6 The needle head of the condensation needle can be designed as a water droplet-shaped structure, which can increase the stress of water and improve the condensation efficiency; at the same time, the water droplet-shaped structure can also effectively reduce the noise caused by airflow disturbance.

[0060] In this embodiment, the needle head of the condensation needle 11 can be designed as a water drop shape for illustration. However, this embodiment is not limited to this. The shape of the needle head of the condensation needle 11 can also be optimized according to different application requirements. For example, different geometric structures such as conical, spherical, and micro-curved shapes can be used to adapt to different condensation environments and working conditions: the conical needle head can provide a more concentrated condensation surface, so that water vapor can condense quickly and slide along the needle surface, thereby reducing the residence time of water droplets; the spherical needle head can increase the surface area, increase the condensation rate, and reduce the condensation resistance caused by the accumulation of water droplets; the micro-curved needle head can optimize the flow path of the water droplets, making the condensed water easier to fall off, and prevent the water droplets from adhering for a long time and affecting the condensation effect.

[0061] In this embodiment, the substrate 1 can be selected from a ceramic substrate 1, a metal substrate 1, and a polymer composite substrate 1, etc.; among them, the ceramic substrate 1 is preferably used. Due to its excellent thermal stability and low thermal expansion coefficient, the ceramic substrate 1 can still maintain structural stability in an environment 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 generating device and reduce the risk of electrical breakdown of the discharge components; at the same time, the corrosion resistance and low hygroscopicity of the ceramic substrate 1 ensure that the substrate 1 can still maintain stable performance in a high humidity environment, thereby extending the service life of the device and improving the reliability of the overall operation.

[0062] The following embodiments involve the Peltier effect, which is when current passes through different materials, the transition of electrons between different materials will lead to the absorption or release of energy, thereby achieving a cooling effect. In this embodiment, the refrigeration unit 12 composed of at least one P-type semiconductor and at least one N-type semiconductor is equivalent to a PN junction. The refrigeration unit 12 uses the Peltier effect to reduce the temperature of the condensation needle 11 so that water vapor in the air can be more effectively condensed on the surface of the condensation needle 11.

[0063] The two ends of the PN junction in the refrigeration unit 12 are respectively a cooling end 121 and a heat dissipation end 122, wherein the cooling end 121 is electrically connected to the condensation needle 11 and is responsible for directly applying the cooling effect to the condensation needle 11, so that its surface temperature is reduced to below the dew point, thereby causing the water vapor in the air to condense into water droplets; the temperature control of the cooling end 121 is very important, if the temperature is too high, the water vapor cannot be effectively condensed, affecting the formation of water droplets; if the temperature is too low, frost may occur, affecting normal operation; in order to maintain a 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 discharging excess heat to avoid excessive system temperature and resulting in a decrease in refrigeration efficiency.

[0064] In this embodiment, the so-called high-voltage discharge unit 2 refers to a component for applying a high voltage to the condensation needle 11, and is used to ionize the water droplets condensed on the surface of the condensation needle 11 by high voltage, so as to decompose and release nano-water ions. The booster unit 3 is used to provide a high-voltage AC power supply to the high-voltage discharge unit 2, and on the basis of the input voltage, the voltage is increased to a level suitable for ionizing water droplets to ensure that the high-voltage discharge unit 2 can work stably.

[0065] The present embodiment further includes a step-down unit 4, which is mainly used 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 a low-voltage DC drive to reduce the temperature of the condensation needle 11. The step-down unit 4 is used to ensure a stable output voltage and prevent the refrigeration unit 12 from operating abnormally or reducing efficiency due to voltage fluctuations.

[0066] In this embodiment, the heat dissipation end 122 is provided with a heat conducting member 13, whose main function 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 member 13 can be made of aluminum alloy, copper-based material, composite phase change material, etc.

[0067] In this embodiment, at least one first heat dissipation hole 14 is further 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 vertically penetrates the entire substrate 1. When the refrigeration unit 12 is working, the air around the cooling end 121 is affected by the condensation needle 11 and the temperature drops, forming a cold air layer. Due to the large density of the cold air, the cold air naturally flows downward under the action of gravity, and enters the heat conductor 13 through the first heat dissipation hole 14 and absorbs the heat accumulated by 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] In the embodiment of the present invention, a heat conductor 13 is arranged at the heat dissipation end 122 of the refrigeration unit 12, and a first heat dissipation hole 14 is provided on the substrate 1, so that the cold air generated by the cooling end 121 can be effectively guided to the heat conductor 13, thereby achieving efficient heat dissipation in a limited space and avoiding the problem of reduced refrigeration efficiency caused by limited heat dissipation in traditional water ion generating devices.

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

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

[0079] In some implementations, the buck circuit 210 further includes a fifth capacitor C5 and a sixth capacitor C6 connected in parallel between the positive terminal and the negative terminal of the first output port J2 to further stabilize the voltage.

[0080] Furthermore, it also includes a plurality of pillars 7, which support the high-voltage discharge part 2 above the substrate 1 to ensure a stable distance between the high-voltage discharge part 2 and the substrate 1, so as to optimize the discharge environment and improve the uniformity and stability of water ion release.

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

[0083] In order to optimize the functional layout of the device and further improve the working efficiency and heat dissipation capacity, the present embodiment also includes a water ion generating chamber 6, which can reasonably distribute the core components and achieve efficient heat dissipation and stable operation in a limited space.

[0084] Specifically, refer to Figure 3 The water ion generating chamber 6 includes a step-down part accommodating chamber 61, a step-up part accommodating chamber 62 and a water ion emitting chamber 63, wherein the step-down part accommodating chamber 61 is used to accommodate the step-down part 4, and the step-up part accommodating chamber 62 is used to accommodate the step-up part 3. There is electromagnetic isolation between the step-down part accommodating chamber 61 and the step-up part accommodating chamber 62, which can effectively prevent electromagnetic interference and ensure the stability of the power supply system; the water ion emitting chamber 63 is used to accommodate the substrate 1 and the high-voltage discharge part 2, that is, the area for emitting nano-water ions. In the water ion emitting chamber 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, in order to further optimize the heat dissipation effect, refer to Figure 3 A heat dissipation cavity 64 is also provided in the water ion generating chamber 6 . The heat dissipation cavity 64 is adjacent to the water ion generating chamber 6 and is specifically used for heat exchange of the heat conducting member 13 .

[0086] Furthermore, a second heat dissipation hole 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 the condensation needle 11, so that the water vapor in the air condenses to form tiny water droplets. In this process, the air around the condensation needle 11 is affected by the low temperature and the temperature drops to form a cold air layer. Due to the high density of the cold air, the cold air naturally flows downward under the action of gravity and enters the heat conductor 13 through the first heat dissipation hole 14. When the cold air absorbs the heat of the heat conductor 13, its temperature gradually increases, and part 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, so that the internal heat can be dissipated in time, avoiding the excessive temperature of the heat dissipation cavity 64 affecting the condensation efficiency of the entire device; at the same time, due to the low 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 cycle 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, the third heat dissipation hole 631, the heat dissipation cavity 64 and the water ion emission cavity 63 jointly promote the air circulation of the water ion generating device, which can effectively discharge the excess heat inside the device and prevent the accumulation of high temperature from affecting the semiconductor refrigeration unit 12. It can also accelerate the air circulation, allow more fresh air to enter the condensation area, increase the water vapor concentration in the air, and thus improve the condensation efficiency.

[0088] In this embodiment, the first heat dissipation hole 14, the second heat dissipation hole and the third heat dissipation hole 631 are taken as examples for illustration. However, this embodiment is not limited to this. The shape, quantity and arrangement of the first heat dissipation hole 14, the second heat dissipation hole 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 hole 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 of this embodiment is not limited to a specific form, but can be flexibly adjusted to meet the heat dissipation needs of different application scenarios.

[0089] In one embodiment, reference Figure 2The water ion generating chamber 6 is also provided with a filter 641 second heat dissipation hole; 65, which is used to suppress static electricity and prevent carbon accumulation on the metal surface in the water ion emission chamber 63. The filter 641 second heat dissipation hole; 65 includes conductive fibers, stainless steel mesh, activated carbon layer and polymer antistatic materials, wherein the conductive fibers can effectively absorb and disperse static charges, the stainless steel mesh provides mechanical support and conductivity, the activated carbon layer is used to adsorb tiny particles and organic matter in the air, and the polymer antistatic material further enhances the static electricity suppression effect, thereby ensuring the long-term stable operation inside the water ion emission chamber 63.

[0090] In one embodiment, reference Figure 3-6 The high voltage discharge portion 2 is provided with a water ion emission port 21 , and a plurality of radially extending protrusions 22 are provided at the periphery of the water ion emission port 21 , and the protrusions 22 are evenly distributed along the circumference of the water ion emission port 21 .

[0091] Furthermore, the number of the protrusions 22 is five or six. After testing, different numbers of protrusions 22 have different effects on the discharge efficiency and release stability of water ions; when the number of the protrusions 22 is six, since the discharge positions are evenly distributed along the circumference and the spacing is small, the release path of the water ions is more dispersed, which can provide a higher discharge efficiency and help to improve the overall output of water ions; when the number of the protrusions 22 is five, since the spacing between the protrusions 22 is relatively large, the discharge path is more centralized, which can make the water ion release area more stable, reduce the diffusion unevenness problem caused by changes in the discharge position, thereby improving the release consistency of water ions.

[0092] Specifically, the outer edge of the protrusion is an arc structure, and its arc angle range is between 5°-85°, and the preferred arc angle range is 37°-52°. When the arc 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 exceeds 52°, the electric field distribution tends to disperse, resulting in a decrease in discharge intensity, thereby affecting the overall discharge efficiency.

[0093] In this embodiment, the number of protrusions 22 is five or six for illustration. However, this embodiment is not limited to this. The number, shape, depth and arrangement of the protrusions 22 can be adjusted according to the 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, such as four, seven or more; in terms of arrangement, the protrusions 22 can be evenly distributed around the water ion emission port 21, or can be unequally distributed to meet 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 also 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 part 2 is further provided with a wiring hole 23, and the high-voltage discharge part 2 is electrically connected to the boost part 3 through the wiring hole 23. The wiring hole 23 is used to electrically connect to the boost part 3 by riveting or screw fixing. Compared with the traditional welding connection method, this embodiment further provides a wiring hole 23 on the high-voltage discharge part 2, so that rivets or other fasteners can be installed, thereby avoiding the problem of material deformation caused by high temperature during welding and ensuring the stability of the discharge part structure.

[0095] In one embodiment, the step-down part 4 and the step-up part 3 are electromagnetically isolated, and a partition 66 is provided between the step-down part accommodating chamber 61 and the step-up part accommodating chamber 62 to effectively reduce electromagnetic interference and improve system stability.

[0096] In one embodiment, the separator 66 is made of a highly conductive material. When electromagnetic waves act on the separator 66, the highly conductive material will generate an induced current on its surface. The induced current can weaken the penetration of the electromagnetic waves, 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 shielding effectiveness.

[0098] In one embodiment, insulating glue, such as epoxy resin composite material, can be filled between the step-down part accommodating cavity 61 and the step-up part accommodating cavity 62, which can not only enhance the insulation performance of the system and prevent high voltage breakdown, but also effectively prevent water and dust from entering, thereby improving the environmental adaptability of the system. At the same time, the filling of insulating glue can also enhance the thermal conductivity, optimize the heat dissipation effect, and further weaken the penetration of electromagnetic waves, thereby improving the overall electromagnetic shielding capability.

[0099] In one embodiment, the water storage tray 5 is sleeved on the condensation needle 11 and adopts a porous structure to optimize the collection and regulation of condensed water. The pores of the water storage tray 5 are filled with absorbent or hydrophilic materials, such as highly absorbent polymers, fiber fabrics or porous water-absorbing media, to adsorb and store condensed water, achieve dynamic balance regulation of condensed water, prevent excessive accumulation of condensed water from affecting discharge stability, or reduce water ion release efficiency due to insufficient condensed water. In addition, the water storage tray 5 can ensure that the discharge environment is maintained in an appropriate humidity range, thereby improving the stability and sustainability of the water ion generating device.

[0100] Furthermore, the surfaces of the high-voltage discharge part 2, the water storage tray 5 and the condensation needle 11 are coated with a coating, which can effectively improve the anti-pollution ability of the components, reduce the adhesion of dust and impurities, ensure the long-term stable operation of the equipment and extend the service life. On the surface of the high-voltage discharge part 2, the coating can reduce the loss of materials caused by arc discharge, improve the discharge uniformity and long-term stability; on the surface of the water storage tray 5, the coating can inhibit the growth of microorganisms, prevent the deposition of scale and dirt, and keep the water storage environment clean; on the surface of the condensation needle 11, the coating can reduce water droplet retention, improve the desorption efficiency of condensed water, and optimize the release process of water ions.

[0101] Specifically, the coating may include fluorinated polymer, silica sol-gel, aluminum oxide, titanium oxide, or boron nitride.

[0102] Furthermore, the substrate 1 is provided with guide ports 15 on both sides along the length direction for draining excess water to prevent the electrolysis performance from being affected by water accumulation.
