Description

Technical Field

[0001] This utility model belongs to the field of water ion generation technology, and specifically relates to a water ion generation device. Background Technology

[0002] In actual production, traditional ionization devices often rely on passive condensation due to ambient humidity or collect water through columnar electrode structures. The water storage area at the top of such columnar electrodes is limited, making it impossible to effectively collect and temporarily store sufficient condensate, resulting in an unstable water supply for ionization. At the same time, the flat columnar surface lacks an effective flow guiding structure, and condensate is prone to interruption, uneven distribution, or dripping before reaching the tip during its transport to the tip, causing intermittent interruptions in the ionization process. It is also difficult to form a water pocket with stable size and regular shape at the predetermined ionization tip. Utility Model Content

[0003] (1) Technical problems to be solved This invention provides a water ion generating device, which aims to solve the problems of unstable water supply for ionization due to the inability to effectively collect and temporarily store sufficient condensate, and the easy occurrence of interruption, uneven distribution, or dripping of condensate before reaching the tip during the process of transporting it to the tip.

[0004] (2) Technical solution This utility model provides a water ion generating device, including a discharge needle. The discharge needle is provided with an emitting end and a heat-conducting end. A condensation section, a transition section and an ionization section are connected end to end along the outer peripheral wall of the discharge needle between the heat-conducting end and the emitting end. The transition section has at least a portion of an inner arc surface, and the tangent L2 at the beginning of the transition section forms an angle A with the central axis L1 of the discharge needle, wherein the angle A is greater than 90 degrees or less than 90 degrees.

[0005] Furthermore, the condensation section is arranged parallel to the central axis L1 of the discharge needle, making the condensation section have a columnar structure.

[0006] Furthermore, the included angle A is less than 90°.

[0007] Furthermore, the entire transition section is an inwardly concave inner arc surface structure.

[0008] Furthermore, the transition section includes a connecting section and a concave section connected end to end. The first end of the connecting section is connected to the end of the condensation section, and the end of the concave section is connected to the first end of the ionization section. The concave section is the inner arc surface structure.

[0009] Furthermore, the connecting segment as a whole has the inner arc surface structure or the outwardly protruding outer arc surface structure.

[0010] Furthermore, the length of the connecting segment is greater than or equal to the length of the concave segment.

[0011] Furthermore, the included angle A is greater than 90°, and the entire transition section connecting segment is an inwardly concave inner arc surface structure.

[0012] Furthermore, along the extension direction of the central axis L1, the axial length of the transition section is less than the axial length of the condensation section.

[0013] Furthermore, the transmitting end is located on the central axis L1.

[0014] Furthermore, it also includes an electrode, a counter electrode ring, and a condensation assembly. The condensation assembly includes a condenser plate and the discharge needle. The condenser plate is heat-transfer connected to the heat-conducting end of the discharge needle, causing the emitting end of the discharge needle to condense moisture in the surrounding air to form a water pocket. The discharge needle is connected to the electrode, so that an ionization region for electrolyzing the water pocket is formed between the emitting end of the discharge needle and the counter electrode ring, so as to electrically break down the water pocket to form water ions / water microparticles.

[0015] Furthermore, the opposing electrode ring is provided with a through hole, and the emitting end of the discharge needle is coaxially arranged with the through hole.

[0016] Furthermore, the condensation assembly also includes a heat sink, which is thermally connected to the condensation fin to improve the heat transfer efficiency between the condensation fin and the discharge needle.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The tangent L2 at the beginning of the transition section forms an angle A with the central axis L1 of the discharge needle, and the angle A is greater than or less than 90 degrees. Compared with the traditional smooth tangent connection (the tangent at the beginning of the transition section coincides with the condensation section), which allows the water film to flow down unimpeded like on a slide and is difficult to accumulate at the tip, the non-tangent design of this application (the tangent at the beginning of the transition section is not perpendicular to the central axis of the discharge needle 32) constitutes a geometrical abrupt change and curvature discontinuity, forming a flow channel contraction design, which significantly enhances the capillary pumping effect, accelerates the directional transport of water to the tip, and stores water pockets, making it difficult for the water pockets formed at the tip of the discharge needle to flow down, while forming stable water pockets at the tip of the discharge needle.

[0018] 2. The inner arc surface design, under the dominance of liquid surface tension, effectively collects and confines the condensate transported here by the turbulent flow, preventing water loss. Compared with flat or convex surfaces and the limited water storage space at the top of traditional columnar structures, the inner arc surface structure can accommodate and temporarily store more condensate, providing valuable buffer and storage space for the water flow from the front end, ensuring the continuity of the ionized water source and the rapid accumulation of water in the water tank.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] like Figure 1-2 As shown, this utility model provides a water ion generating device, including an electrode 1, a counter electrode ring 2, and a condensation assembly 3. The condensation assembly 3 includes a condensation plate 31 and a discharge needle 32. The discharge needle 32 is provided with an emitting end 324 and a heat-conducting end 325. A condensation section 321, a transition section 322, and an ionization section 323 are connected end to end along the outer peripheral wall of the discharge needle 32 between the heat-conducting end 324 and the emitting end 325. The condenser plate 31 is heat-transfer connected to the heat-conducting end 325 of the discharge needle 32, so that the emitting end 324 of the discharge needle 32 condenses the moisture in the surrounding air to form a water bag 5. The discharge needle 32 is connected to the electrode 1, so that an ionization region 4 for electrolyzing the water bag 5 is formed between the emitting end 324 of the discharge needle 32 and the opposing electrode ring 2, so as to electrically break down the water bag 5 to form water ions / water microparticles. The transition section 322 has at least a portion of an inner arc surface 3221. The tangent L2 at the beginning of the transition section 322 forms an angle A with the central axis L1 of the discharge needle 32, and the angle A is greater than 90 degrees or less than 90 degrees.

[0034] It should be noted that the discharge needle 32 itself is made of porous material and has several microchannels inside; A high voltage is applied between the tip of the discharge needle 32 and the opposing electrode ring 2 to form a high voltage electric field, that is, a high voltage electric field is formed in the ionization region 4, which breaks down and ionizes the water bag 5 located in the ionization region 4, decomposing it into water ions or water microparticles.

[0035] In use, according to the Peltier effect, when current passes through, one end of the condenser plate 31 becomes cold as the cooling end and the other end becomes hot as the heating end. The heat-conducting end 325 of the discharge needle 32 is connected to the cooling end. Under the action of the Peltier effect, the condenser plate 31 cools the discharge needle 32 through heat transfer, causing the temperature of the discharge needle 32 to be lower than the dew point temperature of the surrounding air. When humid air flows over its surface, the water vapor in the air condenses into condensate on the discharge needle 32 and adheres to the discharge needle 32. Condensate is attached to the condensation section 321, the transition section 322, and the ionization section 323. At the same time, the condensate attached to the condensation section 321 is spontaneously and continuously transported to the top of the discharge needle 32, i.e., the ionization section 323, through capillary action along the micro-texture of the surface of the discharge needle 32 or the porous structure inside the discharge needle 32. At the same time, such as Figure 5 As shown, when high voltage is applied to the discharge needle 32, the ionization section 323 generates an extremely strong electric field. Since water is a polar molecule, it will be attracted and polarized by the electric field. This electric field force will also exert a pulling force on the condensed water on the condensation section 321 toward the point of strongest electric field, i.e., the ionization section 323, assisting capillary action to gather water to the ionization section 323. When the condensed water attached to the condensation section 321 is transported to the transition section 322 toward the ionization section 323, the surface tension of the condensed water will cause the liquid to shrink its surface area as much as possible, thereby forming a water pocket 5 on the transition section 322 and the ionization section 323. When the condensate moves to the tip of the discharge needle 32, the inwardly concave inner arc surface 3221 on the transition section 322 forms a converging and guiding structure with a specific curvature. Compared to a straight structure, the inwardly concave inner arc surface 3221 on the transition section 322 is closer to the center of the discharge needle 32, resulting in a lower temperature, a greater temperature difference with the air, and higher condensation efficiency. At the same time, the inner arc surface 3221 structure makes the water collection at the top of the discharge needle 32 larger and more stable, storing more water. Furthermore, due to the inward concavity of the inner arc surface 3221, the condensate moves towards the top faster under the action of the electric field, accelerating the water supply speed and facilitating ionization.

[0036] Furthermore, when condensate droplets are collected by the condensation section 321 and flow through the transition section 322, the angle A formed between the end of the condensation section 321 and the beginning of the transition section 322, and this angle A being less than or greater than 90 degrees, creates a geometrical abrupt change or curvature discontinuity at this connection point. This effectively disrupts the continuity of the water film and creates turbulence and obstruction effects on the flow of condensate, providing a collection area for the condensate. Under the dominant influence of liquid surface tension, the condensate tends to shrink its surface area, thus being effectively collected and confined within the low potential energy region formed by the inner arc surface 3221, under the physical guidance of the transition section 322. Under the combined action of the collection effect and the electric field force and surface effect of the ionization section 323, the condensate is continuously and stably transported and shaped, forming a water pocket 5 with stable size and regular shape at the tip of the ionization section 323. Compared with the traditional smooth tangential connection (the tangent at the beginning of the transition section coincides with the condensation section, that is, the transition section is smoothly connected to the transition section), which allows the water film to flow down without obstruction like on a slide and is difficult to accumulate at the tip, the non-tangential design of this application (the tangent at the beginning of the transition section is not perpendicular to the central axis of the discharge needle 32) allows the discharge needle 32 to form a stable water pocket 5 at the tip.

[0037] Specifically, such as Figure 3-5 As shown, the entire transition section 322, from its initial end connected to the condensation section 321 to its final end connected to the ionization section 323, is concave inward to form the inner arc surface 3221. Furthermore, the initial end of the transition section 322 is not tangentially connected to the final end of the condensation section 321; that is, the tangent L2 at the initial end of the transition section 322 forms an angle A with the central axis L1 of the condensation section 321, and this angle A is less than 90 degrees. Compared to a flat or convex surface, the concave inner arc surface 3221 structure can accommodate and temporarily store more condensate, providing a buffer and storage space for the water flow collected from the initial condensation section 321. Simultaneously, when condensate enters the inner arc surface 3221 area, the flow... The change in the cross-sectional shape creates a specific fluid pressure gradient. This gradient, combined with the surface tension of the condensate, generates a driving force pointing towards the ionization section 323, thereby accelerating the directional transport speed of the condensate towards the tip of the ionization section 323. Compared to the traditional smooth tangential connection, which allows the water film to flow down unimpeded like on a slide, making the formed water pocket 5 easy to slip off the top or easily broken, and difficult to accumulate at the tip, this application forms an included angle A of less than 90 degrees, which facilitates the formation of a water pocket with stable size and regular shape at the tip of the ionization section 323. This makes the water pocket 5 stable and not easy to slip off the top of the discharge needle 32, while keeping the water pocket 5 from breaking and making its shape regular.

[0038] Specifically, such as Figure 4 and Figure 5As shown, the condensation section 321 is arranged parallel to the central axis L1 of the discharge needle 32, making the condensation section 321 a columnar structure and the transition section 322 a needle-shaped structure. The abrupt transition from the columnar structure to the needle-shaped structure constitutes a significant flow channel contraction design. This design greatly enhances capillary action because the capillary driving force is significantly enhanced when the liquid is guided from a wide area to a narrow area. Furthermore, the needle-shaped transition section 322 itself is a highly efficient capillary pumping channel, which can actively and quickly accelerate the condensate collected from the columnar condensation section 321 towards the terminal ionization section 323. At the same time, due to the abrupt transition from the columnar condensation section 321 to the needle-shaped structure, the transition section 322 is also a highly efficient capillary pumping channel. The needle-shaped transition section 322 has a significant difference in shape between the two. It utilizes the inherent flow instability of the fluid when flowing through a region where the cross-section narrows sharply to disperse and reorganize the unstable, large-volume liquid flow that may come from the columnar section, preventing the formed water bag 5 from being washed away or dripping due to the liquid flow overrush. After rectification and acceleration, the liquid flow is further guided and constrained by the inner arc surface 3221 of the transition section 322 and is precisely and continuously transported to the tip of the ionization section 323. Finally, at the tip of the ionization section 323, the extremely strong electric field force and the surface tension of the liquid work together to firmly lock the transported condensate, forming a water bag 5 that is fixed in position and stable in shape for efficient ionization.

[0039] Furthermore, such as Figure 4 As shown, along the extension direction of the central axis L1, the axial length S1 of the transition section 322 is less than the axial length S2 of the condensation section 321, so that the condensate transported by capillary action and electric field traction can reach the ionization zone 4 from the collection area in a shorter time and with lower flow resistance, which greatly improves the efficiency of water transport and the response speed of the system.

[0040] Preferably, such as Figure 4-5 As shown, the ionization section 323 is located at the tip of the discharge needle 32, and the emitting end 324 is located on the central axis L1. The ionization section 323 is axially symmetrically distributed along the central axis L1 of the discharge needle 32. Since the electric field lines of the discharge needle 32 are originally axially symmetrically distributed, when the axis of the ionization section 323 is strictly coincident with the axis of the entire discharge needle 32, the ionization section 323 at the top is located on the central axis of this axially symmetrical electric field distribution. This makes the high voltage electric field applied to the ionization section 323 highly uniform and symmetrical in the 360-degree circumferential direction, ensuring that the electric field force can act uniformly on the entire initially formed water bag 5, so that it is uniformly pulled and compressed towards the center, thereby shaping a water bag 5 with a regular shape and a central position. At the same time, the strong electric field at the tip of the ionization section 323 generates a pulling force on the water molecules. Under the coaxial design, the direction of this pulling force is precisely along the axis of the discharge needle 32 and points to the center of space.

[0041] This symmetrical force distribution effectively overcomes the unevenness of gravity and liquid surface tension in any direction, firmly locking the water pack 5 at the absolute center of the needle tip. This prevents the water pack 5 from shifting, vibrating, or dripping due to uneven force, greatly improving the positional stability of the water pack 5. Furthermore, for a centrally located and regularly shaped water pack 5, the distance between the surface area of ​​the water pack 5 and the opposing electrode ring 2 is constant and minimized. This ensures that corona discharge occurs uniformly and synchronously around the entire water pack 5, avoiding the problems of excessive local discharge due to water pack 5 shift, which could lead to ozone generation, or insufficient local discharge, which could lead to incomplete ionization. As a result, the water pack 5 can be ionized uniformly and fully, maximizing the ion production rate per unit time and improving the stability of ion production.

[0042] Preferably, the ionization section 323 is arc-shaped. The arc-shaped structure can form a uniform and moderate strong electric field at the tip, avoiding the problem that the electric field strength may be too high or even uncontrollable due to an infinitely sharp needle tip. At the same time, the arc-shaped tip provides an adhesion substrate with a specific curvature for the condensate. Under the action of surface tension, the water bag 5 will conform to the shape of this substrate to form a droplet with a regular shape and a large contact area.

[0043] Specifically, such as Figure 1 As shown, the opposing electrode ring 2 has a through hole 21, and the emitting end 324 of the discharge needle 32 is coaxially arranged with the through hole 21, so that the radial distance between the tip of the discharge needle 32, i.e. the ionization section 323, and any point on the inner circumference of the opposing electrode ring 2 is completely equal; this ensures that the high voltage electric field presents a highly uniform and symmetrical radial distribution in the ionization region 4, eliminates the local concentration or weak area of ​​the electric field that may be caused by eccentricity, significantly reduces the neutralization loss of ions on the inner wall of the through hole 21, and improves the effective output rate and spatial distribution uniformity of ions.

[0044] Specifically, such as Figure 1 As shown, the condensation assembly 3 also includes a heat sink 33, which is thermally connected to the heating end of the condensation fin 31 to dissipate the heat generated at the heating end of the condensation fin 31, thereby maintaining and improving the heat transfer efficiency of the cooling section. This results in a lower temperature for the condensation fin 31 and a greater temperature difference with the air, leading to more condensate produced per unit time, thus providing a sufficient and stable water source for subsequent water ion ionization.

[0045] This application also provides another embodiment that is easy to process, such as Figure 6-13 As shown: Specifically, such as Figure 6-7As shown, the transition section 322 includes a connecting section 3222 and a concave section 3223 connected end-to-end. The first end of the connecting section 3222 is connected to the end of the condensation section 321, and the end of the concave section 3223 is connected to the first end of the ionization section 323. The concave section 3223 has the structure of the inner arc surface 3221. When high voltage is applied to the discharge needle 32, the ionization section 323 generates an extremely strong electric field. Since water is a polar molecule, it will be attracted by the electric field and... The polarization of the electric field also creates a pulling force on the condensed water on the condensation section 321 towards the point of strongest electric field, i.e., the ionization section 323. This assists capillary action in gathering water into the ionization section 323. When the condensed water attached to the condensation section 321 is transported to the transition section 322 towards the ionization section 323, the surface tension of the condensed water causes the liquid to shrink its surface area as much as possible, thereby forming a water pocket 5 on the transition section 322 and the ionization section 323. The high voltage breaks down and ionizes the water pocket 5 located in the ionization region 4, decomposing it into water ions or water microparticles.

[0046] Specifically, such as Figure 7 As shown, the connecting segment 3222 is generally in the form of the inner arc surface 3221, or the outwardly protruding outer arc surface 3224, or the flat surface 3225. like Figure 7 As shown, when the connecting segment 3222 is designed as a flat surface 3225 or as an inwardly concave inner arc surface 3221 with a curvature different from that of the concave segment 3223, it is easy to process, and the water bag 5 is not easy to slip off the flat surface 3225.

[0047] like Figure 8-10 As shown, when the connecting segment 3222 is designed as an outwardly protruding outer arc surface 3224 structure, the tangent L2 at the beginning of the connecting segment 3222 forms an angle A with the central axis L1 of the discharge needle 32, and the angle A is less than 90 degrees. The shape of the discharge needle 32 in this embodiment is easy to process, and compared with a columnar tip or a straight needle tip, the area of ​​the water bag 5 that can be stored in this embodiment is larger, that is, the more condensed water is stored at the tip, and thus more water ions are ionized.

[0048] Preferably, such as Figure 7 As shown, the length of the connecting segment 3222 is greater than or equal to the length of the concave segment 3223, which greatly reduces the overall processing difficulty and cost, and has higher structural strength and rigidity. At the same time, it ensures that the core function of collecting and storing water is realized by the concave segment 3223.

[0049] This application also provides another embodiment, such as Figure 11-13As shown, the included angle A is greater than 90°, and the entire transition section 322 is an inwardly concave inner arc surface 3221 structure. This design can store a larger area of ​​water bag 5, making it easier to store more water and form a more stable water bag 5. Moreover, the included angle A is greater than 90 degrees, making the formed water bag 5 less likely to slip off the connecting section 3222. The inner arc surface 3221 is designed to be close to the central axis L1 of the discharge needle 32, which makes the condensation of condensate water faster and accelerates the ionization of water ions.

[0050] The following is a detailed explanation of the working principle of this utility model; Current passes through the condenser plate 31, cooling one end. The temperature of the connected discharge needle 32 drops below the dew point. Moist air flows over the low-temperature surface of the discharge needle 32, causing water vapor to condense and adhere to the discharge needle 32. The discharge needle 32 is made of porous material, and its internal microchannels generate strong capillary forces, drawing the condensate from the condensation section 321 to the ionization section 323. After the high voltage is applied, the strong electric field at the needle tip generates a directional attraction force on the water molecules, which, in conjunction with capillary action, accelerates the water flow towards the tip. In the transition section 322 of the discharge needle 32... Its concave inner arc surface 3221 design and the angle A formed by the end of the condensation section 321 and the beginning of the transition section 322, and the angle A being greater than or less than 90 degrees, can effectively collect and temporarily store the delivered water at the tip of the discharge needle 32 to form a regular water bag 5. The water bag 5 is not easy to slip off and maintains a stable shape. The water bag 5 at the tip of the needle is located in the ionization region 4 formed by the discharge needle 32 and the opposing electrode ring 2. The water bag 5 is broken down by high voltage and electrolyzed into charged ions or microparticles, which are then ejected from the center of the opposing electrode ring 2.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
