Description

Technical Field

[0001] This utility model belongs to the field of plant cultivation technology, specifically relating to an oxygen supply device for hydroponic plants. Background Technology

[0002] Hydroponic plant oxygen supply devices are auxiliary equipment used in the hydroponic plant cultivation process. Their main function is to provide an appropriate amount of oxygen to the hydroponic solution and control the dissolved oxygen concentration to meet the respiration needs of the hydroponic plant roots and promote healthy plant growth. In the field of modern horticulture and plant cultivation, hydroponics has received widespread attention due to its advantages such as high efficiency, cleanliness, and ease of management. As a key component of the hydroponic system, the performance and quality of the oxygen supply device have a decisive impact on the overall operation of the hydroponic system and the growth status of the plants. A suitable dissolved oxygen concentration is conducive to the high-quality growth of hydroponic plants, while excessively high or low dissolved oxygen concentrations will affect the normal growth of hydroponic plants. This device can also be used to supply oxygen to fish ponds or to remove organic matter from sewage. This device can be used in water bodies that require long-term oxygen supply in the solution.

[0003] Existing oxygen supply devices have gradually revealed a series of significant limitations and technical problems when handling hydroponic plants of different species, root structures, and growth stages. Specifically, existing oxygen supply devices often cannot precisely control the amount of oxygen released, resulting in oxygen concentrations in the hydroponic solution that are too high or too low. Excessive oxygen concentration may cause oxidative damage to plant roots, inhibiting their normal physiological functions and even leading to root rot and plant burn due to excessive dissolved oxygen. Conversely, insufficient concentration cannot meet the plant's respiration needs, affecting its nutrient absorption and metabolic processes, thereby reducing the plant's growth rate and quality. Furthermore, many... When oxygen supply devices introduce oxygen into the hydroponic solution, the oxygen stays or comes into contact with the water for a short time, resulting in low dissolution efficiency and low oxygen utilization. There is also the problem of uneven oxygen diffusion, causing oxygen to be unevenly distributed throughout the hydroponic solution. This leads to uneven oxygen supply to different parts of the plant roots, resulting in localized hypoxia or hyperxia, further affecting the overall growth of the plant and root development. Furthermore, directly adding oxygen-generating agents to the hydroponic solution cannot automatically control the reaction according to demand, leading to excessively high or low dissolved oxygen concentrations. This results in a large amount of oxygen escaping, low oxygen utilization, and an inability to provide continuous oxygen supply.

[0004] Therefore, the applicant proposes an oxygen supply device for hydroponic plants to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an oxygen supply device for hydroponic plants to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An oxygen supply device for hydroponic plants includes a bottle body with several inlet holes at the lower part of the outer ring. A lower partition is fixedly connected to the middle of the inner cavity of the bottle body. A cover plate is provided on the top of the bottle body. An oxygen outlet pipe is fixedly connected to one side of the top of the cover plate. A locking mechanism is provided on the top of the cover plate. The locking mechanism includes an outer frame. A sleeve rod is provided in the inner cavity of the outer frame. The bottom of the sleeve rod extends through the cover plate into the inner cavity of the bottle body. A bracket is fitted around the outer ring of the sleeve rod. A ring is provided on the top of the lower partition plate. An inner disc is provided in the inner cavity of the ring. A bracket is fixedly connected to the top of the inner disc. A thin rod is provided in the inner cavity of the sleeve rod. One end of the thin rod is fixedly connected to the top of the bracket.

[0008] Preferably, one end of the oxygen outlet tube is fitted with a sealing cap, both ends of the first bracket are fixedly connected to the top of the ring, and a counterweight is fixedly connected to the bottom of the bottle.

[0009] Preferably, the top of the lower partition plate and along the circumference of the lower partition plate are provided with a plurality of square through holes, the top of the lower partition plate is provided with a plurality of mating through holes, and the top of the ring and the top of the inner disk are respectively provided with a plurality of mating through holes.

[0010] Preferably, a gathering cover is fixedly connected to the top of the ring, and the outer ring of the gathering cover has several transmission through holes.

[0011] Preferably, the lower surface of the outer frame is fixedly connected to the top of the cover plate. The inner cavity of the outer frame is provided with two arc-shaped plates. Several rubber contacts are fixedly connected to the inner arc surface of the arc-shaped plates. One of the arc-shaped plates is adapted to the adjacent sleeve rod, and the other arc-shaped plate is adapted to the adjacent thin rod. A balance bar penetrating the side wall of the outer frame is fixedly connected to the outer arc surface of the arc-shaped plates. A handle is fixedly connected to the extension end of the balance bar. Magnet blocks are fixedly connected to both sides of one outer wall of the handle, and the magnet blocks are magnetically connected to the adjacent side of the outer frame.

[0012] Preferably, the lower surface of the ring and the bottom of the inner disc are both in contact with the top of the lower partition, and the bottom of the cover plate is connected to the upper part of the outer ring of the bottle body by screw thread.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This solution utilizes input through-holes, square through-holes, and connecting through-holes to ensure the hydroponic solution flows along a predetermined path and fully contacts the oxygen generator, effectively improving oxygen utilization efficiency and dissolution effect. This avoids problems caused by excessively high or low dissolved oxygen concentrations in the hydroponic solution due to excessively high or low oxygen dissolution and diffusion rates. A coordinated adjustment mechanism involving the ring, inner disc, support frame, sleeve rod, and thin rod, combined with the opening and closing control of the connecting through-holes, allows for precise adjustment of the oxygen dissolution rate, matching the oxygen supply to the oxygen consumption needs of different plants. The design of the outer frame, arc plate, rubber contacts, and magnetic adsorption structure in the locking mechanism ensures structural stability after adjustment, improving operational reliability. The sealing cap and oxygen outlet pipe enhance the device's applicability and flexibility, preventing oxidative damage to plant roots and making it suitable for applications requiring high oxygen concentrations, such as wastewater treatment. Overall, the oxygen supply process achieves efficient, controllable, and stable operation.

[0015] The locking mechanism and its components, including the outer frame, curved plate, rubber contacts, balance bar, and handle, significantly enhance the device's operational flexibility and stability. Specifically, the locking mechanism allows operators to precisely control the opening and closing of the connecting holes on the ring and inner disc by simply rotating the handle, thereby adjusting the contact area between oxygen and hydroponic solution and achieving precise control of the oxygen dissolution rate. The rubber contacts on the inner side of the curved plate ensure a tight fit with other components such as the sleeve rod and thin rod during adjustment, preventing accidental slippage or positional displacement and ensuring operational accuracy and safety. The balance bar not only provides additional support for the curved plate but also enhances the overall structural stability, making operation smoother. Furthermore, after adjustment, the handle is fixed to the outer frame via a magnetic adsorption mechanism, further preventing positional changes caused by external interference and ensuring stable operation of the oxygen supply system. This design greatly improves the device's practicality and reliability, allowing users to flexibly adjust the oxygen supply according to actual needs. It meets the oxygen consumption requirements of different plant growth stages and is also suitable for scenarios requiring dynamic oxygen supply adjustment, such as wastewater treatment, demonstrating the device's superior performance in multi-functional applications.

[0024] Example 1:

[0025] Please see Figure 1 - Figure 4As shown, a hydroponic plant oxygen supply device includes a bottle body 1. The lower part of the outer ring of the bottle body 1 has several input through holes 7. A lower partition 8 is fixedly connected to the middle of the inner cavity of the bottle body 1. A cover plate 3 is provided on the top of the bottle body 1. An oxygen outlet pipe 4 is fixed and connected to one side of the top of the cover plate 3. A locking mechanism 6 is provided on the top of the cover plate 3. The locking mechanism 6 includes an outer frame 601. A sleeve rod 11 is provided in the inner cavity of the outer frame 601. The bottom of the sleeve rod 11 extends through the cover plate 3 into the inner cavity of the bottle body 1. A bracket 13 is sleeved on the outer ring of the sleeve rod 11. A ring 15 is provided on the top of the lower partition 8. An inner disc 16 is provided in the inner cavity of the ring 15. A bracket 2 14 is fixedly connected to the top of the inner disc 16. A thin rod 12 is provided in the inner cavity of the sleeve rod 11. One end of the thin rod 12 is fixedly connected to the top of the bracket 2 14.

[0026] One end of the oxygen outlet tube 4 is fitted with a sealing cap 5, both ends of the bracket 13 are fixedly connected to the top of the ring 15, and a counterweight 2 is fixedly connected to the bottom of the bottle body 1.

[0027] As shown above, when hydroponic plants need oxygen, the liquid enters the interior of bottle 1 through the inlet hole 7. Then, the liquid flows upwards through the square throughlet hole 9 on the lower partition 8, entering the outer ring area of ​​the gathering cover. Afterwards, the liquid enters the inner cavity of the gathering cover through the transmission throughlet hole, where it comes into contact with the oxygen-generating agent inside the cavity and undergoes a chemical reaction, generating oxygen. The contact between the hydroponic solution and the oxygen ensures that the oxygen dissolves evenly in the water. The generated oxygen gradually accumulates in the upper part of the inner cavity of bottle 1, forming a certain pressure, which pushes the hydroponic solution level down. When the liquid level is lower than the upper partition, the hydroponic solution reacts with the oxygen-generating agent... The reaction stops when the oxygen-generating agent separates, oxygen is consumed, the pressure decreases, the liquid level rises again to contact the oxygen-generating agent, and the reaction continues, ensuring a certain amount of oxygen stored inside the bottle 1, thus enabling the device to produce oxygen for a relatively long time. During this process, if the operator needs to adjust the oxygen diffusion rate, this can be achieved by operating the locking mechanism 6. Specifically, when it is necessary to connect the connecting through hole 10 on the ring 15 with the connecting through hole 10 on the lower partition 8, the operator pulls out the arc-shaped plate 602 corresponding to the sleeve rod 11, then rotates the sleeve rod 11, and drives the ring 15 to rotate through the bracket 13, causing the ring 15 to... The connecting hole 10 on plate 5 and the connecting hole 10 on the lower partition plate 8 form a connected channel, through which hydroponic solution or oxygen can be transferred. Similarly, when it is necessary to adjust the connecting hole 10 on the inner disc 16, the above operation can be repeated. After the operation is completed, the operator pushes the handle 605 so that the magnet connected to the handle 605 is attracted to one side of the outer frame 601, thereby ensuring the stability of the arc plate 602. Furthermore, through the cooperation between the arc plate 602 and the rubber contact 603, it is ensured that the position of the sleeve rod 11 and the thin rod 12 will not change unexpectedly. By rotating the ring 15 or the inner... The disc 16 allows the connecting hole 10 to be in an open or closed state, thereby changing the contact area between oxygen and hydroponic solution, and thus regulating the rate at which oxygen dissolves in water, so that the oxygen consumption rate of hydroponic plants matches the oxygen dissolution rate; when the oxygen concentration in the water is less than 1 / 3 of the dissolved oxygen saturation concentration, the plants will not suffer oxidative damage due to high oxygen concentration; if used in scenarios requiring higher oxygen concentrations, such as wastewater treatment, the sealing cap 5 on the oxygen outlet pipe 4 can be removed directly, allowing the wastewater to react directly with the oxygen generator, and the continuously generated oxygen will dissolve directly in the water outside the bottle to meet the oxygen supply needs of different application scenarios;

[0028] This solution, through the design of the input through-hole 7, square through-hole 9, and connecting through-hole 10, allows the hydroponic solution to flow along a predetermined path and fully contact the oxygen-generating agent, thereby improving oxygen utilization and dissolution efficiency. This solves the problem of excessively high or low oxygen dissolution and diffusion rates in existing oxygen supply devices, which leads to excessively high or low dissolved oxygen concentrations in the hydroponic solution. It ensures that oxygen is evenly distributed in the water, avoiding localized hypoxia or hyperxia, thus promoting healthy root development. Secondly, through the design of the ring 15, inner disc 16, support 13, and sleeve... The linkage adjustment mechanism of rod 11 and thin rod 12, combined with the opening and closing control of the connecting hole 10, can flexibly adjust the contact area between oxygen and hydroponic solution, thereby achieving precise control of the oxygen dissolution rate into the water. This solves the problem that existing oxygen supply devices cannot dynamically adjust the oxygen supply according to plant species, root structure, and growth stage, ensuring that the oxygen supply matches the actual oxygen consumption of the plant. This avoids oxidative damage to plant roots due to excessive oxygen concentration or inhibition of normal physiological functions due to excessively low oxygen concentration. Furthermore, the locking mechanism... The design of the outer frame 601, arc plate 602, rubber contact 603, handle 605, and magnetic adsorption structure in component 6 allows operators to effectively lock the positions of the sleeve rod 11 and thin rod 12 after adjustment, preventing adjustment failure due to external disturbances. This ensures the operational stability of the oxygen supply system and enhances the practicality and reliability of the device. Furthermore, the device, through the sealing cap 5 and oxygen outlet pipe 4, allows users to choose whether to allow the water to react directly with the oxygen-generating agent, continuously dissolving the generated oxygen directly into the water outside the bottle. In hydroponic plant applications, this prevents root damage caused by excessive oxygen concentration. In wastewater treatment and other applications, it can directly release high-concentration oxygen to enhance oxidation and degradation efficiency, expanding the device's applicability and improving its versatility and adaptability. In summary, this device has optimized the design of each stage of oxygen generation, dissolution, adjustment, and release, not only improving oxygen supply efficiency and utilization but also achieving dynamic adjustment and stable control of the oxygen supply process. This effectively solves the problems of uncontrollable oxygen release, low dissolution efficiency, and uneven distribution in existing technologies.

During the workflow, when it is necessary to adjust the oxygen release, the oxygen output can be controlled by removing the sealing cap 5. Simultaneously, the fixed connection between the bracket 13 and the ring 15 enhances structural stability and ensures the precision of rotational operation. The design of the counterweight 2 ensures the stability of the entire device in a liquid environment, preventing it from tipping over due to water flow or external disturbances. This design achieves stable oxygen supply and precise control of oxygen release, and improves the overall stability of the device. Several square through holes 9 are provided along the circumference of the top of the lower partition 8 to allow for... The top of the ring 15 and the top of the inner disc 16 are each provided with several connecting through holes 10. During the workflow, the hydroponic solution enters the outer ring of the gathering cover through the square through holes 9, and further contacts the oxygen generator through the transmission through holes to generate oxygen. The presence of the connecting through holes 10 allows for flexible adjustment of the gas-liquid channels as needed, achieving precise control of the oxygen dissolution rate. This design optimizes the gas-liquid mixing efficiency, automatically regulates the reaction between water and the oxygen generator through gas pressure, and improves the utilization rate of oxygen and the persistence and stability of oxygen supply. It effectively solves the problems of uncontrollable oxygen generation, low oxygen utilization rate, and unstable, uneven, and unsustainable oxygen supply, as well as the inability to precisely adjust oxygen supply, found in traditional devices. A gathering cover is fixedly connected to the top of the ring 15, and the outer ring of the gathering cover has several transmission through holes. During the working process, the liquid enters the interior of the gathering cover through these transmission through holes, and generates oxygen after fully contacting the oxygen-generating agent.

This solution achieves the effects of enhancing oxygen production efficiency, ensuring sufficient contact between the liquid and the oxygen-generating agent, and improving the oxygen generation rate.

This design not only simplifies the operation steps, but also improves the safety and accuracy of the operation. It achieves the effect of convenient and safe adjustment of oxygen supply, improving the user experience.
