Description

Technical Field

[0001] This invention belongs to the field of medical and health care equipment technology, and specifically relates to a negative pressure air-jet negative oxygen ion generator. Background Technology

[0002] Currently, negative oxygen ions are widely used and promoted in the medical and healthcare fields, playing a positive role in promoting human health. There are currently several methods for artificially generating negative oxygen ions in the air, including high-voltage discharge, water droplet segmentation, thermal electron flow, and radiation. Most negative oxygen ion generators on the market use the high-voltage discharge method, which uses a negative high-voltage tip and ground electrode discharge to ionize the air and generate negative oxygen ions. In this method, oxygen molecules easily decompose into oxygen atoms during the discharge process. Oxygen atoms are unstable and easily combine with oxygen molecules to form ozone. Therefore, the negative oxygen ions and ozone produced by this type of generator are symbiotic. Ozone is chemically very reactive, has a strong oxidizing effect, and is highly irritating to the respiratory mucosa, harming human health. Current regulations stipulate that the ozone content of negative oxygen ion generators should be less than 0.1 ppm. Thermal electron flow and radiation methods also produce ozone, while the water droplet segmentation method produces virtually no ozone. However, water droplet segmentation air ion generators currently face technical challenges such as large size and high manufacturing costs. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention provides a negative pressure air-jet negative oxygen ion generator. When a high-pressure airflow (air or oxygen) flows through a narrow section, a local negative pressure zone is formed (Venturi principle). Due to the pressure difference, water is drawn out to the high-speed airflow nozzle and broken up, thereby generating negative oxygen ion air with properties and functions equivalent to those generated in the natural environment.

[0004] The specific plan is as follows: A negative pressure air-jet type negative oxygen ion generator is assembled inside a water storage container. The water storage container consists of a detachably connected upper shell and a lower shell. The upper shell is provided with a compressed gas inlet, a negative oxygen ion outlet, and a pressure relief device. A connecting pipe, an air jet component, and a negative pressure water suction component are connected sequentially from top to bottom in the middle of the inner cavity of the water storage container. The compressed gas inlet is connected to the upper end of the air jet component through the connecting pipe. The upper section of the connecting pipe is fitted with an upper and lower water collection tank and a water baffle. A sound insulation barrier is fitted on the outer side of the air jet component and the negative pressure water suction component. A filter component is connected to the lower end of the negative pressure water suction component through a water suction pipe. The sound insulation barrier has a cylindrical structure with notches on the front and rear sides of its lower edge and a sealing ring at the lower end.

[0005] Furthermore, a vent is provided on the top surface of the upper shell, and the pressure relief device blocks the vent by the gravity of a metal component.

[0006] Furthermore, the compressed gas inlet is located on the top surface of the upper shell, and the negative oxygen ion outlet is located on the upper side of the upper shell.

[0007] Furthermore, the water-blocking component includes upper and lower water-blocking plate assemblies. Each water-blocking plate assembly consists of multiple fan-shaped baffles evenly distributed along the circumferential direction, and the fan-shaped baffles of the upper and lower layers are staggered, with a gap of at least 1 mm between each layer.

[0008] Furthermore, the water collection tank has a funnel-shaped structure that is smaller at the top and larger at the bottom, with a ring-shaped water tank on the top and bottom, and a drain outlet on the side.

[0009] Furthermore, the airflow jet component and the negative pressure suction component are inserted and assembled vertically. The airflow jet nozzle on the side of the airflow jet component is positioned directly opposite the negative pressure suction outlet at the upper end of the negative pressure suction component. The center-to-center distance between the airflow jet nozzle and the negative pressure suction outlet is less than 10mm. The diameter of the airflow jet nozzle is 0.3-2.5mm, the diameter of the negative pressure suction outlet is 0.3-3.5mm, and the opening of the negative pressure suction outlet is provided with a 3-45° bevel angle for the formation of negative pressure.

[0010] The beneficial effects of this invention are as follows: 1. This invention allows for the selection of appropriate generators based on the same principle according to different pressure and flow rates of the gas source, such as single-outlet, dual-outlet, triple-outlet, quadruple-outlet, etc. Multiple identical generators can also be connected using a splitter, thereby effectively solving the problem of increasing the concentration of negative oxygen ions in large spaces. 2. This invention is located above the water surface, so the amount of water in the container will not affect the concentration of negative oxygen ions generated by the generator, and it can output a high concentration of negative oxygen ions stably and effectively for a long time. 3. Compared to existing underwater impact generators on the market, if users do not remove the remaining water, the generator will be submerged in water for a long time, causing scale buildup that can clog the generator's air outlet and lead to generator failure. This invention, located above the water surface, effectively prevents this problem. 4. This invention has low noise; existing underwater generators on the market generate noise when the airflow is turbulent in the water at high speed, and the bubbles will produce a popping sound when they rise to the surface; in this generator, the high-speed airflow is sprayed onto the sound insulation plate, and the water vapor impacts the sound insulation plate a second time, increasing the concentration of negative oxygen ions while isolating the noise inside the sound insulation plate, effectively reducing the noise level of the generator. 5. The present invention has a simpler structure, lower implementation cost, and higher economic benefits. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] like Figure 1 As shown, the present invention provides a negative pressure air-jet type negative oxygen ion generator, which is assembled in a water storage container. The water storage container consists of a detachably connected upper shell 1 and a lower shell 2. The upper shell 1 is provided with a compressed gas inlet 3 (compressed air or oxygen), a negative oxygen ion outlet 4, and a pressure relief device 5.

[0022] like Figure 2As shown, the inner cavity of the water storage container is connected from top to bottom to a connecting pipe 8, an air jet component 9, and a negative pressure water suction component 10. The compressed gas inlet 3 is connected to the upper end of the air jet component 9 through the connecting pipe 8. The upper section of the connecting pipe 8 is fitted with a water collection trough 6 and a water baffle 7 arranged vertically. The outer sides of the air jet component 9 and the negative pressure water suction component 10 are fitted with a sound insulation barrier 12. The lower end of the negative pressure water suction component 10 is connected to a filter component 11 through a water suction pipe. The sound insulation barrier 12 is a cylindrical structure with notches on the front and rear sides of its lower edge and a sealing ring 13 at the lower end.

[0023] This invention is located above the water surface, so the concentration of negative oxygen ions generated is not affected by the water level. It also effectively prevents the generator from becoming clogged due to scale buildup from prolonged immersion in water. Furthermore, it allows for the free combination of different types or numbers of generators based on the pressure and flow rate of compressed gas (air or oxygen), resulting in higher flow rates and concentrations of negative oxygen ions, thus solving the problem of increasing negative oxygen ion concentration in large spaces. This structure also operates with lower noise, is simpler in design, and has a lower implementation cost.

[0024] like Figure 3 As shown, the top surface of the upper shell 1 is provided with a vent. The pressure relief device 5 blocks the vent by the weight of the metal part 14. When the air pressure inside the container is too high and exceeds the weight of the metal part, it will push the metal part open, and the airflow will be discharged out of the container through the vent, thus releasing the internal pressure of the container (acting as a protective device). The weight of the metal part can be adjusted according to different pressure relief values.

[0025] like Figure 4 As shown, the water-blocking component 4 includes upper and lower water-blocking plate assemblies. Each water-blocking plate assembly consists of multiple fan-shaped baffles evenly distributed along the circumferential direction, and the fan-shaped baffles of the upper and lower layers are staggered. When the high-speed airflow (air or oxygen) impacts the water column, it generates a large number of negative oxygen ions and a large amount of water vapor. The water vapor rises with the airflow to the water-blocking component. When the large water droplets in the water vapor pass through the water-blocking component, they condense on the fan-shaped baffles of the water-blocking component and slide down into the water container. The air (or oxygen) containing negative oxygen ions rises into the upper shell of the container through the staggered gaps between the upper and lower layers. The structure implemented in this scheme is a two-layer multi-petal staggered layout, where the multi-petal structure can be two, three, or more petals, or it can be designed as a multi-layer (two or more layers) staggered structure. To ensure the smooth passage of the negative oxygen ion airflow, the gap between each layer is at least 1 mm.

[0026] like Figure 5As shown, the water collection tank 6 has a funnel-shaped structure that is smaller at the top and larger at the bottom. The top surface and bottom edge are annular water tanks, and there is a drain on the side. When the high-speed airflow (air or oxygen) impacts the water column, it generates a large number of negative oxygen ions and a large amount of water vapor. When the water vapor rises, it passes through the water baffle to remove most of the large water droplets, but a small amount of water vapor remains. When the small amount of water vapor passes through the space between the top water collection tank and the upper shell of the container, it will condense or liquefy into liquid water. The surface of the water collection tank is designed with an arc, and a drain is opened at the bottom tank structure. The liquid water slides down the arc structure into the water tank at the bottom of the surrounding area and flows into the water container for recycling through the drain.

[0027] like Figure 6 As shown in Figure a, the airflow jet component 9 and the negative pressure water suction component 10 are assembled vertically, with the airflow jet nozzle 91 on the side of the airflow jet component 9 directly opposite the negative pressure water suction outlet 101 at the upper end of the negative pressure water suction component 10 (e.g., ...). Figure 6 As shown in b: the airflow nozzle of the airflow jet component is horizontal, and the negative pressure suction outlet of the negative pressure suction component is vertical (the center lines of the two holes intersect at 90°), and the center distance between the airflow jet nozzle 91 and the negative pressure suction outlet 101 is less than 10mm. The diameter of the airflow jet nozzle 91 is 0.3-2.5mm, the diameter of the negative pressure suction outlet 101 is 0.3-3.5mm, and the opening of the negative pressure suction outlet 101 is provided with a 3-45° bevel (e.g., Figure 6 As shown in c), it is used to form negative pressure. Under a high-speed airflow (air or oxygen) at a pressure of 0.15 MPa, the concentration of negative oxygen ions can reach more than 4 million.

[0028] The working principle of this invention is as follows: like Figure 7 As shown, a high-speed airflow (air or oxygen) enters through the air inlet on the upper shell, passes through the connecting pipe into the air jet component, and exits from the small-diameter air jet nozzle. When the high-speed airflow (air or oxygen) passes through the negative pressure water suction outlet, a negative pressure is created (Venturi principle). Due to the pressure difference, water inside the container is drawn to the negative pressure water suction outlet. The drawn-out water is abruptly broken up by the high-speed airflow (air or oxygen) to form high-speed water vapor, simultaneously generating a high concentration of negative oxygen ions. This high-speed water vapor is then sprayed onto the side wall of the soundproof barrier, where it undergoes a second impact and explosion, generating an even higher concentration of negative oxygen ions. The negative oxygen ion air (containing water vapor) rises and passes through the water baffle. Large water droplets condense on the water baffle and flow into the container for recycling. The negative oxygen ion air enters the space between the upper shell of the container and the water collection tank through the channel between the upper and lower layers of the water baffle. The water vapor condenses or liquefies into liquid water and slides down the arc-shaped structure of the water collection tank to the water tank at the bottom of the surrounding area. Then, it flows into the water container for recycling through the water leakage holes on the water tank. Finally, the negative oxygen ion air (or oxygen) after dehumidification flows out from the air outlet of the upper shell.

[0029] Furthermore, this invention allows for the selection of suitable generators based on the same principle according to different pressure and flow rates of the gas source, such as single-outlet, dual-outlet, triple-outlet, quadruple-outlet, etc. (e.g.) Figure 8 (See the left figure), multiple identical generators can also be connected using a splitter (e.g., Figure 8 (See the right figure), thus effectively solving the problem of increasing the concentration of negative oxygen ions in a large space. This implementation case uses a single double-hole structure design.

[0030] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
