Description

Technical Field

[0001] This utility model relates to the field of cultivation equipment technology, and more specifically, to a plant oxygenation cultivation device. Background Technology

[0002] Plant oxygenation cultivation is a cultivation technique designed around "optimizing the oxygen supply in the plant growth environment". Its core is to increase the oxygen concentration in the rhizosphere (around the roots) or the growth environment of plants through active intervention, so as to meet the needs of plant root respiration, nutrient absorption and metabolic activities. It is especially suitable for the problem of "insufficient natural oxygen supply" in different cultivation scenarios such as soil cultivation, hydroponics and aeroponics.

[0003] The core logic is that plant roots need to generate energy through aerobic respiration to drive the absorption of water and nutrients. If the soil is compacted, the hydroponic solution is oxygen-deficient, or the high humidity environment leads to insufficient oxygen, it will cause problems such as decreased root vitality and root rot. Aerobic cultivation actively replenishes oxygen through soil aeration devices (aeration pipes inserted into soil culture), maintains stable oxygen levels in the rhizosphere, and ultimately promotes plant growth and enhances stress resistance. It is commonly used in vegetable seedling cultivation, flower planting, and the cultivation of high-value-added crops.

[0004] Patent No. 201821709192.3 discloses a plant oxygenation cultivation device. By setting an oxygenation device at the bottom of the pot, the oxygenation device connects the oxygenation chamber to the planting cavity above the oxygenation chamber through an oxygenation pipe, supplying oxygen to the planting cavity for plant root absorption. The operating time of the oxygenation device is set by a control module to achieve automatic oxygenation to ensure normal plant growth. It can be widely used in plant substrate cultivation.

[0005] However, in actual use, the unreasonable structural design of its oxygenation pipe and ventilation opening, and the lack of protective structure, will cause the soil adjacent to the ventilation opening in the planting chamber to become loose during long-term ventilation, and it is easy to fall from the ventilation opening into the oxygenation chamber, which will eventually cause blockage.

[0006] Secondly, the automatic watering equipment is too complicated and takes up a lot of space. With the oxygenation pipe already installed, it is easy for it to get tangled with the plant's roots, causing inconvenience to the plant's growth and transplanting. Moreover, it is not easy to clean after long-term use. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a plant oxygenation cultivation device, including a cultivation pot, a base installed at the bottom of the cultivation pot, and a support ring installed at the bottom of the base. The inner cavity of the cultivation pot is provided with a longitudinally extending main pipe. The bottom end of the main pipe extends through the base to the inner side of the support ring and is detachable. Several oxygenation pipes are installed on the outer wall of the main pipe. The oxygenation pipes extend from the outer wall of the main pipe, bend downward and extend towards the base. A diversion pipe is provided on the inner side of the support ring. The end of the diversion pipe bends and extends upward. The bottom end of the main pipe extending to the inner side of the support ring is inserted into the interior of the diversion pipe. A three-way valve is provided on one side of the diversion pipe. The two ports of the three-way valve are respectively connected to an air inlet pipe and a water inlet pipe.

[0008] In a preferred embodiment, the base has a through hole with an inner diameter that matches the outer diameter of the main pipe. The main pipe extends through the through hole to the inside of the support ring.

[0009] In a preferred embodiment, the top end of the main pipe is closed and the bottom end is open. The outer wall of the bottom end of the main pipe and the inner wall of the end of the branch pipe are provided with matching threads, and the bottom end of the main pipe is detachable from the end of the branch pipe through the threads.

[0010] In a preferred embodiment, raised anti-slip teeth are installed on the outer wall of the top of the main pipe, and the height of the top of the main pipe is lower than the height of the top of the cultivation pot.

[0011] In a preferred embodiment, a connecting post is connected between the diverter pipe and the lower surface of the base, and the base is also provided with a number of vent holes, which are staggered from the positions of the diverter pipe, the three-way valve, the air inlet pipe, and the air inlet pipe.

[0012] In a preferred embodiment, a connecting pipe connects the diverter pipe and the three-way valve, and both the air inlet pipe and the water inlet pipe extend through the support ring to the outside of the support ring.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention, through its downward-bending oxygenation pipe design and detachable threaded connection between the main pipe and the branch pipe, avoids the cultivation substrate from falling and clogging the oxygenation channel, solving the problem of easy clogging of the oxygenation pipe in traditional devices. By integrating the air inlet pipe and water inlet pipe with a three-way valve, and using the main pipe and oxygenation pipe as a shared gas-liquid transport channel, no additional independent irrigation pipeline is required. This prevents the pipeline from entangled in the plant roots and facilitates transplanting, saves space and is easy to maintain, and optimizes the overall rhizosphere growth environment.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figure 1-3 The plant oxygenation cultivation device shown includes a cultivation pot 1, a base 2 installed at the bottom of the cultivation pot 1, and a support ring 3 installed at the bottom of the base 2. The inner cavity of the cultivation pot 1 is provided with a longitudinally extending main pipe 4. The bottom end of the main pipe 4 passes through the base 2 and extends to the inner side of the support ring 3 and is detachable. Several oxygenation pipes 5 are installed on the outer wall of the main pipe 4. The oxygenation pipes 5 extend from the outer wall of the main pipe 4, bend downward and extend towards the base 2. A diversion pipe 6 is provided on the inner side of the support ring 3. The end of the diversion pipe 6 bends and extends upward. The bottom end of the main pipe 4 extending to the inner side of the support ring 3 is inserted into the interior of the diversion pipe 6. A three-way valve 7 is provided on one side of the diversion pipe 6. The two ports of the three-way valve 7 are respectively connected to an air inlet pipe 8 and a water inlet pipe 9.

[0021] Based on the above, the main pipe 4 is the core carrier for gas-liquid transport. Its bottom end is connected to the branch pipe 6 to form a flow channel, and the top end is closed to ensure that gas and liquid are output only through the oxygenation pipe 5. The design of the oxygenation pipe 5, which is "bent downward and facing the base", allows gas / liquid to be directly transported to the plant rhizosphere (close to the cultivation substrate), avoiding gas and liquid waste or inadequate delivery. The bending design can also prevent soil slippage and blockage at the oxygenation point. The three-way valve 7 realizes the switching control of "oxygen inlet" and "water inlet", eliminating the need for an additional independent irrigation pipeline. The integrated structure of "main pipe + oxygenation pipe" avoids the problem of oxygenation pipe and irrigation pipe entanglement with the root system in traditional devices, while simplifying the structure and saving space. External oxygen enters from the air inlet pipe 8 and water from the water inlet pipe 9, and after passing through the three-way valve, branch pipe, main pipe, and oxygenation pipe, it is finally targeted to the rhizosphere to meet the plant's respiration and irrigation needs.

[0022] The base 2 has a through hole 10, the inner diameter of which is adapted to the outer diameter of the main pipe 4. The main pipe 4 passes through the base 2 through the through hole 10 and extends to the inner side of the support ring 3.

[0023] Based on the above, the inner diameter of the through hole 10 is adapted to the outer diameter of the main pipe 4, which allows the main pipe 4 to pass through the base 2 stably, preventing the main pipe from shifting due to shaking during gas-liquid transportation, ensuring the sealing of the connection between the "main pipe and the branch pipe", and providing a smooth path for the main pipe to be disassembled, which is convenient for subsequent disassembly and maintenance.

[0024] The top end of the main pipe 4 is closed and the bottom end is open. The outer wall of the bottom end of the main pipe 4 and the inner wall of the end of the branch pipe 6 are provided with matching threads. The bottom end of the main pipe 4 can be detached from the end of the branch pipe 6 through the threads.

[0025] Based on the above, the threaded connection design allows the main pipe 4 and the branch pipe 6 to be detached. On the one hand, it is convenient to remove the main pipe when transplanting plants to avoid the pipes obstructing the root system. On the other hand, after long-term use, the main pipe and the oxygenation pipe can be removed to clean the internal residual substrate, prevent blockage, and ensure delivery efficiency.

[0026] The outer wall of the top of the main pipe 4 is equipped with raised anti-slip teeth 11, and the height of the top of the main pipe 4 is lower than the height of the top of the cultivation pot 1.

[0027] Based on the above, the raised anti-slip teeth 11 can increase the friction between the hand and the top of the main pipe 4, making it convenient for operators to align the main pipe with the through hole 10 of the base 2 during installation, or to unscrew the main pipe to separate its threaded connection with the branch pipe 6 during disassembly, thus avoiding hand slippage and inconvenience in operation; the top of the main pipe 4 is lower than the top of the cultivation pot 1, which can prevent the main pipe from protruding from the edge of the cultivation pot and interfering with the substrate filling, or scratching the plant stems and leaves during plant growth, ensuring that the space inside the cultivation pot is used reasonably and does not affect the normal growth of the plant.

[0028] A connecting post 12 connects the diversion pipe 6 to the lower surface of the base 2. The base 2 is also provided with several vent holes 13, which are offset from the positions of the diversion pipe 6, the three-way valve 7, the air inlet pipe 8, and the water inlet pipe 9.

[0029] Based on the above, the connecting column 12 can fix the diversion pipe 6 to the lower surface of the base 2, so as to prevent the diversion pipe from shaking due to airflow impact or water pressure during gas-liquid transportation, which would cause the connection between it and the main pipe 4 and the connecting pipe 14 to loosen, thus ensuring the stability of the gas-liquid transportation link; the ventilation hole 13 is staggered from the bottom transportation component, which can prevent the diversion pipe, three-way valve and other components from blocking the ventilation hole, ensuring that the ventilation hole is unobstructed, assisting the air circulation inside and outside the cultivation pot 1, and forming a dual oxygen supply of "active oxygenation + passive ventilation" in conjunction with the active oxygenation of the oxygenation pipe 5, further maintaining the stability of the root zone oxygen concentration, while removing excess moisture in the cultivation pot, preventing the high humidity environment from causing root hypoxia and root rot, and preventing the substrate from falling from the ventilation hole and clogging the bottom component.

[0030] A connecting pipe 14 connects the diversion pipe 6 and the three-way valve 7. The air inlet pipe 8 and the water inlet pipe 9 both extend through the support ring 3 to the outside of the support ring 3.

[0031] Based on the above, the air inlet pipe 8 and the water inlet pipe 9 extend outward through the support ring 3. On the one hand, this allows the external air pump and water source to be easily connected to the device. On the other hand, the support ring 3 can fix and protect the extended air inlet pipe and water inlet pipe, making it suitable for cultivation scenarios with limited space, such as homes and small greenhouses.

[0032] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
