Description

Technical Field

[0001] This invention relates to the technical field of negative oxygen ion generating equipment, specifically to a ring electrode water-jetting negative oxygen ion generator device and method. Background Technology

[0002] Currently, most common negative ion generators use pure high-voltage corona discharge technology. While the high-voltage tip discharge ionizes the air to produce negative ions, the high-energy electrons colliding with oxygen molecules inevitably produce ozone byproducts. Excessive ozone levels can irritate the human respiratory system. Furthermore, the free-state negative ions generated by simple discharge have a short residence time in the air. They easily neutralize and dissipate with positive charges in the air, resulting in lower concentrations of negative ions far from the generator.

[0003] Some existing negative ion generators attempt to incorporate water to assist in their generation. However, the combination of water mist and negative ions lacks the induced polarization effect of an external electric field, making it difficult for the mixture to form structurally stable hydrated negative ions, ultimately resulting in a short lifespan for the negative ions. Furthermore, most conventional generators use fixed air outlet structures. Fixed outlets cannot dynamically adjust the release position according to different indoor spaces and personnel activity heights. This single, fixed release height limits the diffusion range of negative ions within the environment, causing the coverage area to be limited by the physical structure of the generator, making it difficult to meet the dynamic release needs of complex spatial environments.

[0004] Therefore, this invention proposes a ring electrode water-jetting negative oxygen ion generator device and method to overcome the shortcomings of the prior art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a ring electrode water-jet negative oxygen ion generator device and method, which solves the problems of ozone byproducts associated with traditional high-voltage discharge type negative oxygen ion generators, short retention time and easy dissipation of conventional free negative oxygen ions, and the limitation of negative oxygen ion diffusion and absorption range caused by the fixed height of the negative oxygen ion release structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a ring electrode water hammer negative oxygen ion generator device, including a body, and a water circulation component, a negative oxygen ion generation component, a high voltage ring electric field charging component, and an air duct release component arranged sequentially from bottom to top along the fluid flow inside and at the top of the body; The water circulation component provides water to the negative oxygen ion generating component; the negative oxygen ion generating component converts the water into a fine water mist and discharges it; the high-voltage ring electric field charging component polarizes the fine water mist particles into charged water mist; and the air duct release component releases the high concentration of hydrated negative oxygen ions, which are a combination of charged water mist and negative oxygen ions, from the device to the outside.

[0007] The negative ion generating component includes a drive motor installed inside the device body, and the output end of the drive motor is connected to a rotating shaft via a coupling; a fan blade is connected circumferentially to the top of the outer wall of the rotating shaft, and an atomizing nozzle is provided on the top of the outer wall of the fan blade; a water flow channel is provided inside the rotating shaft, and a water delivery hole communicating with the water flow channel is opened at the top of the outer wall of the rotating shaft, and the atomizing nozzle is in fluid communication with the water delivery hole; the inner wall area inside the device body corresponding to the water throwing trajectory of the fan blade forms the inner wall of the pipe, and the surface of the inner wall of the pipe is provided with a corrugated collision texture structure.

[0008] The water circulation assembly includes a support plate horizontally installed at the bottom of the vessel body. A water tank is located at the bottom of the support plate, and a miniature submersible pump is installed inside the water tank. One end of the miniature submersible pump is electrically connected to a power supply. A water delivery pipe connected to the top of the miniature submersible pump passes through the support plate and is connected to a rotary joint. The inner wall of the rotary joint is rotatably connected to the outer wall of the rotating shaft, and the inner cavity of the rotary joint is connected to the water flow channel. A filter device is also installed inside the bottom of the vessel body.

[0009] The air duct release assembly includes an air duct 1 and an air duct 2 coaxially and tightly fitted inside the air duct 1, with a release port connected to the top of the air duct 2; the high-voltage ring electric field charging assembly includes a ring electrode coaxially installed on the outer side of the middle part of the air duct 1, the ring electrode being electrically connected to a high-voltage power supply, a mounting bracket being fixedly connected to the outer wall of the high-voltage power supply, the right end of the outer wall of the mounting bracket being fixedly connected to the inner wall of the top of the device, and an electric field control module containing an electric field strength sensor and a feedback control circuit being electrically connected to the high-voltage power supply.

[0010] The inner wall of the first duct is axially and equidistantly equipped with multiple annular grooves, and longitudinally connected adjustment grooves are provided between the multiple annular grooves; the bottom end of the outer wall of the second duct is fixedly connected with locking columns on the front and rear sides, and the locking columns are slidably connected to the inner walls of the annular grooves and adjustment grooves.

[0011] The negative oxygen ion generating component includes a drive motor and a rotating shaft connected to the output end of the drive motor. An ultrasonic atomizer is provided at the end of the rotating shaft, and the atomization frequency of the ultrasonic atomizer is 1.7MHz. The water circulation component is connected to the rotating shaft and provides a water source. The generator device also includes a negative ion concentration display screen that detects the concentration of negative oxygen ions in the environment through a negative ion concentration sensor and displays it in real time on an LED screen.

[0012] The innovative principle of this invention lies in the following: a drive motor rotates the fan blades, and a miniature submersible pump delivers water to the atomizing nozzle. The atomizing nozzle shears the water flow into tiny water droplets. These tiny water droplets, propelled by the centrifugal force generated by the rotating fan blades, impact the inner wall of the pipe, which has a corrugated textured surface, producing intense friction. Based on the Lenard effect and the principle of triboelectricity, the water splits into large, wall-mounted droplets and negatively charged tiny water mist particles. Simultaneously, oxygen molecules in the air capture free electrons to form negative oxygen ions. The mixture containing the tiny water mist particles and negative oxygen ions enters the first duct. A high-voltage DC power supply applies a high-voltage DC voltage to the ring electrode, generating a high-voltage ring electric field. Under the influence of this field, the tiny water mist particles polarize, forming charged water mist. The high-voltage ring electric field limits the field strength below the air molecule breakdown threshold, restricting ozone production. The polarized charged water mist and negative oxygen ions attract and combine, forming hydrated negative oxygen ions. Finally, the hydrated negative oxygen ions are discharged through the release port along the second duct, achieving the generation and release of pure hydrated negative oxygen ions. The rotating release port causes the locking pin to slide within the annular groove and the adjustment groove, thereby achieving physical adjustment of the release port height.

[0013] This invention provides a device and method for generating negative oxygen ions using a ring electrode water-jetting process. It offers the following advantages: 1. This invention drives a motor to rotate the fan blades and atomizing nozzle at high speed, causing tiny water droplets to collide at high speed with the inner wall of the pipe, which has a corrugated collision texture structure, under the action of centrifugal force. Combining the Lenard effect and the principle of triboelectricity, the water splits and oxygen molecules in the air capture free electrons to form negative oxygen ions. This avoids the ozone generation defect of the pure high-voltage discharge technology route, and achieves pure and safe generation of negative oxygen ions.

[0014] 2. This invention generates a high-voltage ring electric field through an externally installed ring electrode in the air duct. Tiny water mist particles pass through the high-voltage ring electric field, become polarized, and form charged water mist. The charged water mist attracts and combines with negative oxygen ions to form stable and static-free high-concentration hydrated negative oxygen ions. At the same time, the electric field control module limits the electric field strength of the high-voltage ring electric field to below the air molecule breakdown threshold, thus preventing the generation of ozone byproducts.

[0015] 3. This invention utilizes multiple annular grooves on the inner wall of the first air duct to cooperate with a longitudinally connected adjustment groove. Combined with a locking column fixedly connected to the bottom of the outer wall of the second air duct, rotating the release port causes the second air duct and the locking column to slide horizontally within the annular grooves. When the locking column aligns with the adjustment groove, the second air duct and the release port rise and fall vertically. The locking column screws into the corresponding annular groove to lock the height, thus achieving purely mechanical and physical adjustment of the release height of hydrated negative oxygen ions and meeting the release requirements of different spatial environments.

One end of the pump is electrically connected to a power supply 307, and a water delivery pipe 303 is fixedly connected to the top of the miniature submersible pump 302.

[0025] The outer wall of the water pipe 303 extends upward through the support plate 301, and a rotary joint 306 is fixedly connected to its top. The inner wall of the rotary joint 306 is rotatably connected to the outer wall of the rotating shaft 208, and the inner cavity of the rotary joint 306 completely covers and connects to the water flow channel 206, thereby achieving leak-proof water supply at the junction of static and dynamic states.

The filter device 305 is preferably an activated carbon filter, which is used to remove impurities and odors from the circulating water after large water droplets collide and fall, so as to realize the closed-loop utilization of water resources.

[0027] Please see the appendix Figure 5 Appendix Figure 6 and attached Figure 7 The air duct release component 4 is used to release high-concentration hydrated negative oxygen ions, which are a combination of charged water mist and negative oxygen ions, from inside the device 1 to the outside. The air duct release component 4 includes an air duct 401 installed at the top of the device 1. As a carrier of the electric field, the air duct 401 is an insulated cylindrical pipe made of ceramic with a smooth inner wall surface. Its diameter is set to 50-300mm and its length is set to 100-1000mm. An air duct 402 is coaxially installed inside the air duct 401. The air duct 402 is tightly fitted to the inner wall of the air duct 401, and a funnel-shaped release port 403 is fixedly connected to the top of the outer wall of the air duct 402.

[0028] Please see the appendix Figure 5 and attached Figure 6 The high-voltage annular electric field charging component 5 is used to polarize water mist particles into charged water mist. This component includes an annular electrode 501, which is installed on the outer side of the middle of the air duct 401.

The high-voltage power supply 502 is a DC power supply with an output voltage controlled between 1-30kV. One end of the high-voltage power supply 502 is electrically connected to an electric field control module 503 via a wire. The electric field control module 503 contains an electric field strength sensor and a feedback control circuit, which is used to monitor and adjust the intensity of the high-voltage ring electric field in real time. The outer wall of the high-voltage power supply 502 is fixedly connected to a mounting bracket 504. The right end of the outer wall of the mounting bracket 504 is fixedly connected to the inner wall of the top of the device body 1.

[0030] As another preferred embodiment, the annular electrode water-jet negative oxygen ion generator device can use three annular electrodes 501 instead of a single annular electrode 501, and use an ultrasonic atomizer instead of the atomizing nozzle 204 on the fan blade 202, which can improve atomization efficiency. At the same time, a negative ion concentration display screen can be added to display the ambient negative oxygen ion concentration in real time.

[0031] The ultrasonic atomizer is located at the end of the rotating shaft 208, with an atomization frequency of 1.7MHz, producing water mist particles with a more uniform size of about 5-10 micrometers. The negative ion concentration display screen can detect the concentration of negative oxygen ions in the environment through a negative ion concentration sensor and display it on the LED screen in real time.

[0032] This implementation method is suitable for small spaces such as homes and offices, and features small size (approximately 30cm×20cm×40cm), light weight (approximately 5kg), and easy operation.

[0033] As another preferred embodiment, the ring electrode water-jet negative oxygen ion generator is portable, powered by a lithium battery with a capacity of 5000mAh and a battery life of about 8 hours. The generator has a size of 15cm×10cm×8cm and a weight of about 800g. The fan blade 202 has a diameter of 80mm, the drive motor 201 has a power of 15W and a speed of 3000rpm, the high voltage power supply 502 has an output voltage of 3kV, and a single ring electrode 501 is set on the outer wall of the air duct.

[0034] Tests showed that the portable generator device of this embodiment can produce a negative oxygen ion concentration of approximately 2 × 10⁻⁶ at a distance of 30 cm. 6 Units per cm³, meeting individual needs for close-range respiratory health care, suitable for personal use or vehicle use. Please see the appendix Figure 7 In another preferred embodiment, the annular electrode water-jet negative oxygen ion generator device also includes multiple annular slots 6, which are axially equidistantly installed on the inner wall of the first air duct 401. Adjustment grooves 7 are longitudinally connected between the multiple annular slots 6. Locking posts 8 are fixedly connected to the front and rear sides of the bottom end of the outer wall of the second air duct 402. The outer walls of the multiple locking posts 8 are slidably connected to the inner walls of the annular slots 6 and adjustment grooves 7. The outer walls of the multiple locking posts 8 are tightly fitted to the inner walls of the annular slots 6, and the two can maintain relative stability through friction. Through the cooperation of the multiple annular slots 6, adjustment grooves 7, and locking posts 8, the height of the release port 403 can be physically adjusted.

[0035] Please see the appendix Figure 8 Based on the above-mentioned annular electrode water-jet negative oxygen ion generator device, the present invention also provides a method for using the annular electrode water-jet negative oxygen ion generator device, the specific steps of which are as follows: Step S1: Turn on the water pump to deliver water from the water tank 304 to the atomizing nozzle 204 at the top of the fan blade 202 via the miniature submersible pump 302. Then turn on the drive motor 201 to drive the fan blade 202 to rotate at a high speed of 1000-5000 rpm (preferably 2000 rpm). Then turn on the high voltage power supply 502 to apply a DC high voltage of 1-30kV (preferably 5kV) to the external annular electrode 501.

[0036] Step S2: Water flows through the water channel 206 inside the rotating shaft 208 to the water inlet 207, and through the space inside the fan blade 202 to the atomizing nozzle 204, where it is atomized into tiny water droplets with a particle size in the range of 10-200 micrometers (preferably 50-100 micrometers). The atomized tiny water droplets are driven by the high-speed rotating fan blade 202 and are thrown out at a linear velocity of 10-50m / s (preferably about 30m / s) under the action of centrifugal force, and impact the textured inner wall 203 of the outer pipe at high speed.

[0037] Step S3: The water droplets collide and rub violently with the inner wall 203 of the pipe. According to the Lenard effect and the principle of triboelectricity, the water splits into large water droplets with positive charges and tiny water mist particles with negative charges. The large water droplets hang on the outer wall of the inner wall 203 and flow downwards, eventually passing through the support plate 301 and flowing back to the water tank 304 for recycling. At the same time, oxygen molecules in the air capture free electrons to form negative oxygen ions (O2-). The mixed substances generated by the collision include water mist (main peak particle size of about 80nm), negative oxygen ions and air.

[0038] Step S4: The mixture containing water mist and negative oxygen ions is carried into the insulated air duct 401 by the wind-driven airflow. Passing through the high-voltage annular electric field region, under the action of the electric field generated by the annular electrode 501, the water mist particles undergo a charging effect, forming charged water mist. The electric field control module 503 precisely controls the electric field strength of the high-voltage annular electric field within the range of 0.5-10kV / cm (preferably 2-5kV / cm). The residence time of the water mist particles in the electric field is 0.1-5 seconds, ensuring that the water mist can be fully charged while remaining below the air molecule breakdown threshold, thereby ensuring that no ozone is generated. Subsequently, the polarized charged water mist and negative oxygen ions attract and combine with each other to form stable, static-free, high-concentration hydrated negative oxygen ions (O2-(H2O)n).

[0039] Step S5: High concentration of hydrated negative oxygen ions after charging (tested concentration can reach 10). 6 -10 8 With an ozone concentration of less than 0.01 mg / m³, the ions are evenly released into the indoor space through the release port 403 at the end of the air duct under the propulsion of the airflow, forming a high-concentration negative oxygen ion health environment.

[0040] Step S6: When it is necessary to adjust the release height, the user can rotate the release port 403, so that the air duct 402 drives the locking column 8 to rotate horizontally in the annular groove 6. When the locking column 8 rotates to the longitudinal adjustment groove 7, the release port 403 can be moved vertically up and down, so that the locking column 8 moves to another annular groove 6 corresponding to the required height and screws in, locking the height of the locking column 8, thereby realizing convenient adjustment of the release port 403 and the air outlet height.
