Description

Technical Field

[0001] This invention relates to the field of flower cultivation technology, specifically to a flowerpot with a self-regulating irrigation system. Background Technology

[0002] Seed and seedling cultivation pots are an indispensable infrastructure in modern horticultural production, and their design and application directly affect the quality and efficiency of early crop growth. As the starting point of a plant's life journey, cultivation pots not only carry seeds and substrates but also serve as a crucial support for the precision and intensive development of agriculture. Functionally, cultivation pots are not only physical containers but also micro-environmental control units. Combined with modern greenhouse environmental control technology, cultivation pots can provide stable temperature and humidity conditions for seedlings, significantly shortening the seedling cycle and improving uniformity and stress resistance. Furthermore, the promotion of compostable and biodegradable seedling pots is gradually reducing plastic pollution, aligning with the concept of green and low-carbon agricultural development.

[0003] If the humidity inside a flowerpot cannot be effectively regulated for a long period, it will pose a systemic threat to the health of the plant. Persistent overwatering is a common and fatal condition. When the soil is constantly saturated with water, air is forced out of the pores, causing the roots to suffocate and rot. This is not only physical damage but also provides a breeding ground for anaerobic bacteria in the soil, leading to the rapid spread of diseases such as root rot. Once the root system is damaged, the growth of the above-ground parts of the plant will stop, manifesting as chlorosis, wilting, yellowing, and shedding of leaves, resulting in an overall withered appearance and potentially leading to the death of the entire plant. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a flowerpot with a self-regulating irrigation system, comprising a water tank and a planting pot, the planting pot being made of aluminum alloy, and further comprising: A pumping mechanism is installed inside the water tank to draw nutrient solution stored in the tank into the planting pot. The water tank serves as the storage and supply unit for nutrient solution or water in the irrigation system, and its capacity is designed to meet the water requirements of plants for extended periods, reducing the inconvenience of frequent watering. The planting pot, the core container holding the soil and plants, has a drainage structure at its bottom to prevent waterlogging and root rot. The pumping mechanism, as the "heart" of the system, is responsible for lifting and transporting the liquid stored at the bottom of the water tank to the planting pot, providing the active power for irrigation and achieving bottom-up water supply. An adjustment mechanism is used to regulate the moisture content of the soil in the planting pot. This mechanism is fixed inside the planting pot. The adjustment mechanism is a key component for the system to achieve its "self-regulation" function; it can automatically change the infiltration rate or flow rate of irrigation water according to the soil moisture status, thus achieving intelligent water control. A hygrometer is used to detect the humidity inside the planting pot, and the hygrometer is installed inside the cavity of the planting pot. By setting up the hygrometer as the "sensing organ" of the system, the moisture content of the soil layer in the planting pot is monitored in real time, and the humidity data is converted into an electrical signal to provide a decision-making basis for the entire regulation system; A support ring is fixed to the top of the water tank, and a transfer ring is slidably connected to the inner cavity of the support ring.

The connecting pipe connects the adjustment mechanism of the planting pot to the transfer ring; the connection port is slidably and sealingly connected to the bottom end of the connecting pipe. This design allows the planting pot to detach from the transfer ring, thus enabling the installation and separation of the planting pot from the base, greatly improving the convenience and flexibility of use.

[0005] Preferably, the pumping mechanism includes a shim cylinder with an outer diameter smaller than the inner diameter of the water tank. A shim block is fixed on the lower surface of the shim cylinder. The number of shim blocks is several, and the several shim blocks are evenly distributed.

The inner cavity of the adapter cylinder is connected to the inner cavity of the raised cylinder through the permeable holes. A water pump passes through the upper surface of the adapter cylinder, and a straight pipe is fixedly provided at the top of the water pump. The bottom end of the straight pipe passes through the lower surface of the intermediate ring.

[0007] Preferably, a water-absorbing cylinder is fixedly provided on the top surface of the inner cavity of the elevating cylinder, and a number of evenly distributed round holes are opened on the lower surface of the water-absorbing cylinder. The water-absorbing cylinder is connected to the inner cavity of the adapter cylinder through water-permeable holes. A funnel is fixedly provided at the top opening of the elevating cylinder, and a sieve screen is fixedly provided at the opening of the funnel. A number of evenly distributed drainage holes are opened on the lower surface of the planting pot.

[0008] Preferably, a wrapping tube extends through the outer side of the planting pot, the wrapping tube is inclined, and the hygrometer is located inside the wrapping tube.

[0009] Preferably, the adjusting mechanism includes a dividing ring, which is fixed to the inner wall of the planting pot, dividing the inner wall of the planting pot into a space. The top end of the connecting pipe is located in the space formed by the dividing ring and the planting pot. A permeable ring is fixed to the bottom end of the dividing ring, which is fixed to the bottom surface of the inner cavity of the planting pot. A plurality of evenly distributed holes are formed on the outer surface of the permeable ring.

[0010] Preferably, the upper surface of the dividing ring is provided with a number of water spray nozzles, which are evenly distributed. A sealing ring is fixed on the upper surface of the dividing ring, and the outer ring of the sealing ring is fixed on the upper surface of the dividing ring. The sealing ring can deform upward.

[0011] Preferably, a permeable ring is fixed on the outer surface of the dividing ring, the bottom end of the permeable ring is squeezed and adapted to the inner wall of the planting pot, the top end of the permeable ring and the inner wall of the planting pot form an annular water distribution chamber, an annular inclined groove is opened on the top of the permeable ring, the annular water distribution chamber is located between the annular inclined groove, the dividing ring and the planting pot, a plurality of flow channels are evenly opened on the annular inclined groove, the flow channels are used to connect the annular water distribution chamber and the bottom of the permeable ring, a fixing ring is fixed on the inner wall of the planting pot, and a first support rod is fixed on the lower surface of the fixing ring.

[0012] Preferably, a spring is fixed to the bottom end of the first support rod, a second support rod is fixed to the bottom end of the spring, and a wedge-shaped blocking plate is fixed to the bottom end of the second support rod. The wedge-shaped blocking plate is squeezed and adapted to the annular inclined groove opened on the surface of the water-permeable ring, and several wedge-shaped blocking plates are evenly distributed. The number of wedge-shaped blocking plates is adapted to the number of flow channels. The wedge-shaped blocking plates seal the opening of the flow channel located in the annular water distribution chamber by fitting with the annular inclined groove.

[0013] This invention provides a flowerpot with a self-regulating irrigation system. It has the following beneficial effects: 1. This flowerpot with a self-regulating irrigation system uses a water tank as a storage and supply unit for nutrient solution or water. Its capacity is designed to meet the water requirements of plants for a longer period, reducing the inconvenience of frequent watering. The planting pot, the core container holding the soil and plant, has a drainage structure at the bottom to prevent waterlogging and root rot.

[0014] Second, the flowerpot with a self-regulating irrigation system has a pumping mechanism, which acts as the "heart" of the system. This mechanism is responsible for lifting and transporting the liquid stored at the bottom of the water tank to the planting pot, providing active power for irrigation and achieving water supply from bottom to top.

[0015] Third, the flowerpot with a self-regulating irrigation system, through the setting of an adjustment mechanism, is the key component for the system to realize the "self-regulation" function. It can automatically change the infiltration rate or flow rate of irrigation water according to the soil moisture status, so as to realize intelligent water control.

[0016] IV. This flowerpot with a self-regulating irrigation system incorporates a hygrometer as its "sensor," which monitors the soil moisture content in real time and converts the moisture data into electrical signals to provide decision-making support for the entire regulation system. A protective sleeve, angled and inserted into the soil on the side of the pot, allows the hygrometer probe to penetrate deeper and more representatively into the soil, rather than remaining only on the surface. This sleeve also protects the hygrometer from direct soil pressure and facilitates future sensor replacement or maintenance. The hygrometer and connecting wires together form the system's soil moisture sensing unit. The hygrometer probe detects changes in the dielectric constant or resistance of the surrounding soil, thus accurately measuring the volumetric water content. The connecting wires transmit the measured analog or digital signals to an external processor, providing real-time data input for automatic irrigation decisions and forming the basis for intelligent control.

[0017] V. This flowerpot with a self-regulating irrigation system, through the setting of a spring, a second support rod, and a wedge-shaped blocking plate, together constitutes a mechanical feedback regulating valve. The spring provides downward preload, and the wedge-shaped end of the blocking plate is in close contact with the outer surface of the permeable ring. When water flows into the inner cavity of the dividing ring, the wedge-shaped blocking plate blocks the permeable ring, thereby preventing liquid from entering the bottom space of the dividing ring, and then spraying water from the nozzle into the soil. When it is necessary to extract excess water from the inner cavity of the planting pot, the water pump generates suction, and the inside of the dividing ring generates suction, thereby moving the wedge-shaped blocking plate away from the permeable ring. At this time, the water accumulated at the bottom of the planting pot will enter the inner cavity of the dividing ring through the permeable ring, and finally be drawn back into the inner cavity of the water tank.

[0020] 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 invention to the forms disclosed. 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 application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figures 1-13As shown, this invention provides a technical solution: a flowerpot with a self-regulating irrigation system, including a water tank 1 and a planting pot 6. The planting pot 6 is made of aluminum alloy, which is corrosion-resistant and reusable. The planting pot 6 is a seed and seedling cultivation pot used for seed and seedling cultivation. It also includes a pumping mechanism 5, which is used to pump the nutrient solution stored in the inner cavity of the water tank 1 into the inner cavity of the planting pot 6. The pumping mechanism 5 is located in the inner cavity of the water tank 1. By setting up the water tank 1, it serves as the storage and supply unit for the nutrient solution or water of the irrigation system. Its capacity design can meet the water requirements of plants for a long time, reducing the trouble of frequent watering. By setting up the planting pot 6, it serves as the core container for carrying soil and plants. Its bottom is designed with a drainage structure to prevent water accumulation and root rot. By setting up the pumping mechanism 5, it serves as the "heart" of the system, responsible for lifting and transporting the liquid stored at the bottom of the water tank 1 to the planting pot 6, providing active power for irrigation and realizing bottom-up water supply. Hygrometer 12 is used to detect the humidity inside the planting pot 6. The hygrometer 12 is installed in the inner cavity of the planting pot 6. By setting up the hygrometer 12 as the "sensing organ" of the system, the moisture content of the soil layer in the planting pot 6 is monitored in real time, and the humidity data is converted into an electrical signal to provide a decision-making basis for the entire regulation system. A support ring 2 is fixed to the top of the water tank 1. A transfer ring 3 is slidably connected to the inner cavity of the support ring 2. A connecting pipe 9 is symmetrically inserted through the outer side of the planting pot 6. A connection port 8 is opened on the upper surface of the transfer ring 3. The bottom end of the connecting pipe 9 is slidably connected to the connection port 8 on the upper surface of the transfer ring 3. The connecting pipe 9 connects the adjustment mechanism 7 of the planting pot 6 to the transfer ring 3. The connection port 8 is slidably and sealed to the bottom end of the connecting pipe 9, which facilitates the disassembly of the planting pot 6. This design allows the planting pot 6 to be detached from the transfer ring 3, thereby separating and installing the planting pot 6 from the base, greatly improving the convenience and flexibility of use.

[0022] The pumping mechanism 5 includes a raised cylinder 51, the outer diameter of which is smaller than the inner diameter of the water tank 1. Several raised blocks 4 are fixed to the lower surface of the raised cylinder 51, and these blocks are evenly distributed. The lower surface of each raised block 4 is pressed against the bottom surface of the inner cavity of the water tank 1. The raised cylinder 51 and the raised blocks 4 form the mounting base and bottom water inlet channel of the pumping mechanism 5. The raised cylinder 51 serves as a mounting bracket for components such as the water pump 54; its outer diameter is smaller than the inner diameter of the water tank 1, forming an annular water inlet channel with the inner wall of the water tank 1. The evenly distributed raised blocks 4 elevate the entire raised cylinder 51, maintaining a certain gap between its bottom and the bottom surface of the water tank 1. This gap ensures that even when the liquid level in the water tank 1 is low, the liquid can flow smoothly from the sides and bottom of the raised cylinder 51 into its internal space and be drawn in by the water pump 54, avoiding the problems of suction or poor water intake caused by direct contact with the bottom surface, and improving the working efficiency and reliability of the water pump 54.

[0023] The outer surface of the raised cylinder 51 has several evenly distributed permeable holes 52. A connecting cylinder 53 is fixed to the outer surface of the raised cylinder 51. The inner cavity of the connecting cylinder 53 is connected to the inner cavity of the raised cylinder 51 through the permeable holes 52. A water pump 54 passes through the upper surface of the connecting cylinder 53. A straight pipe 55 is fixed to the top of the water pump 54, and the bottom end of the straight pipe 55 passes through the lower surface of the intermediate ring 3. The permeable holes 52 are water inlets on the wall of the raised cylinder 51, allowing water from inside the raised cylinder 51 to enter the inner cavity of the connecting cylinder 53, serving as the source inlet for liquid extraction. By setting up the connecting cylinder 53, a transitional cavity is created connecting the raised cylinder 51 and the water pump 54. It collects the liquid flowing in from the permeable holes 52 and provides a stable and direct water inlet environment for the water pump 54, optimizing the water inlet flow. The water pump 54, the core power component of the pumping mechanism 5, is a low-power, quiet micro submersible pump. When powered on, it generates suction to pump out the liquid collected in the transfer cylinder 53. Simultaneously, under control, it can generate reverse suction to extract water from the inner cavity of the planting pot 6. A straight pipe 55 serves as the outlet pipe for the water pump 54, vertically transporting the pumped liquid upwards. Its bottom end passes through and is fixed to the transfer ring 3, thus connecting the outlet of the power unit to the rotating hub, ensuring that the liquid can continue to be transported upwards to the planting pot 6 through the transfer ring 3.

[0024] A water suction cylinder 56 is fixedly installed on the top surface of the inner cavity of the raised cylinder 51. The lower surface of the water suction cylinder 56 has several evenly distributed circular holes. The water suction cylinder 56 is connected to the inner cavity of the adapter cylinder 53 through water permeable holes 52. A funnel 57 is fixedly installed at the top opening of the raised cylinder 51, and a sieve screen 58 is fixedly installed at the opening of the funnel 57. Several evenly distributed drainage holes 10 are opened on the lower surface of the planting pot 6. By setting the water suction cylinder 56, located above the interior of the raised cylinder 51, the circular holes on its lower surface form a water inlet barrier. Its main functions are twofold: first, it serves as physical protection for the suction port of the water pump 54, preventing larger particles or impurities that may have accumulated at the bottom of the water tank 1 from being directly sucked into the pump body and causing damage; second, its cylindrical structure allows for the extraction of liquid from the bottom of the water tank 1. By setting the funnel 57 and the sieve screen 58, a filtration and diversion device is formed when adding liquid to the water tank 1. The funnel 57 facilitates pouring; the sieve 58 effectively intercepts solid impurities such as fallen leaves and mud that may be present in the added liquid, preventing them from entering the water tank 1 and contaminating the water quality or clogging subsequent pipes, thus maintaining the cleanliness of the system. The drainage hole 10, located at the bottom of the planting pot 6, is a traditional flowerpot drainage structure. Its function is to drain excess irrigation water or rainwater, preventing the soil from becoming too wet during the seedling stage, which could lead to root rot due to lack of oxygen. This is a fundamental design feature to ensure healthy plant growth. The drainage hole 10 and the adjustment mechanism 7 do not conflict in their drainage methods; together, they form a dual drainage system combining "passive safety protection" and "active intelligent control." First, their functions differ: the drainage hole 10 is a traditional passive gravity drainage structure essential for flowerpots, always open. It automatically overflows when the water level in the planting pot 6 exceeds the bottom surface, preventing root rot caused by extreme waterlogging—a basic physical protection. When the internal water flow is insufficient to drain by gravity and the internal humidity remains too high, the regulating mechanism 7 activates. The regulating mechanism 7 is the core innovation of this invention. It senses soil moisture through the hygrometer 12. When the soil moisture is too wet but not yet waterlogged, the processor instructs the water pump 54 to reverse, generating negative pressure. Excess water is actively drawn back to the water tank 1 for recycling via components such as the permeable ring 72 and the wedge-shaped blocking plate 710, achieving precise closed-loop control. The fluid paths are independent: the drainage hole 10 discharges water directly outside the pot, an open-loop discharge; the regulating mechanism 7 draws water back to the water tank 1 for recycling, a closed-loop recovery, and they do not interfere with each other. Structurally, the drainage hole 10 is located at the bottom of the pot, while the drainage components of the regulating mechanism 7 are located on the inner side wall and bottom of the pot, resulting in spatial separation. The two work together to build a complete humidity control system, moving from passive to active and from open-loop to closed-loop, to jointly ensure the health of plant roots.

[0025] A wrapping tube 11 runs through the outer surface of the planting pot 6. This wrapping tube 11 is angled, and a hygrometer 12 is housed within its inner cavity. The wrapping tube 11 acts as a protective sleeve, angled and inserted into the soil on the side wall of the planting pot 6. Its angled design allows the probe of the hygrometer 12 to penetrate deeper into the soil to a more representative location in the main root distribution area, rather than remaining only on the surface. Simultaneously, the sleeve protects the hygrometer 12 from direct soil pressure and facilitates future sensor replacement or maintenance. Together, the hygrometer 12 forms the soil moisture sensing unit of the system. The probe of the resistive soil moisture sensor 12 detects changes in the dielectric constant or resistance of the surrounding soil, thereby accurately measuring the volumetric water content. The measured analog or digital signals are transmitted to an external processor, providing real-time data input for automatic irrigation decisions, which is the foundation for intelligent control.

[0026] The regulating mechanism 7 is used to regulate the moisture content of the soil in the planting pot 6. The regulating mechanism 7 is fixedly installed inside the planting pot 6. This regulating mechanism 7 is a key component for the system to achieve its "self-regulation" function. It can automatically change the infiltration rate or flow rate of irrigation water according to the soil moisture status, achieving intelligent water control. Ultimately, during the breeding and seedling process, it prevents excessive or insufficient water for the plant roots, which could affect the normal growth of the plant. The regulating mechanism 7 includes a dividing ring 71, which is fixed to the inner wall of the planting pot 6, creating a space between the dividing ring 71 and the inner wall of the planting pot 6. The top of the connecting pipe 9 is located in the space formed by the dividing ring 71 and the planting pot 6. A permeable ring 72 is fixed to the bottom of the dividing ring 71, and its bottom end is fixed to the bottom surface of the inner cavity of the planting pot 6. Several evenly distributed holes are formed on the outer surface of the permeable ring 72. By setting the dividing ring 71, a ring-shaped water distribution chamber is created inside the planting pot 6. This chamber temporarily stores and evenly distributes irrigation water from the connecting pipe 9, preventing direct impact of water flow on localized soil areas and achieving uniform circumferential distribution of irrigation water, thus creating conditions for subsequent slow-release infiltration. A permeable ring 72, connected to the bottom of the dividing ring 71, is one of the core components of the regulating mechanism 7 for extracting excess water from the soil. Its evenly distributed pores on its outer surface form initial, fixed infiltration channels.

[0027] The upper surface of the dividing ring 71 has several water spray nozzles 73, which are evenly distributed. A sealing ring 74 is fixed to the upper surface of the dividing ring 71. The outer ring of the sealing ring 74 is fixed to the upper surface of the dividing ring 71, and the sealing ring 74 can deform upward. The outer ring of the lower surface of the sealing ring 74 is fixedly connected to the surface of the dividing ring 71, while the inner ring of the lower surface is not fixedly connected to the dividing ring 71. Therefore, when the sealing ring 74 is subjected to upward pressure, it will flip over, thus no longer blocking the water spray nozzles 73 on the surface of the dividing ring 71. The water spray nozzles 73 are located on the upper surface of the dividing ring 71 and serve as channels for irrigation water to enter the upper soil layer, allowing the liquid required for seedling cultivation to flow evenly to the plant roots. When water needs to be injected into the soil, the water flows from the water spray nozzles 73 into the inner cavity of the planting pot 6. The sealing ring 74 is an elastic annular seal that covers the water spray nozzles 73. Under normal conditions, the nozzle 73 is covered by gravity or a slight pre-tightening force to prevent soil from falling into the water distribution chamber. When the water pressure inside the chamber is high enough, the water flow can push the sealing ring 74 upward, thereby opening the nozzle 73; after the water pressure drops, the sealing ring 74 springs back and closes again. This forms a simple automatic pressure valve, realizing the automatic opening and closing of the nozzle 73.

[0028] A permeable ring 75 is fixedly provided on the outer surface of the dividing ring 71. The bottom end of the permeable ring 75 is squeezed and adapted to the inner wall of the planting pot 6. The top end of the permeable ring 75 and the inner wall of the planting pot 6 form an annular water distribution chamber. Specifically, an annular inclined groove 711 is provided on the top of the permeable ring 75. The annular water distribution chamber is located between the annular inclined groove 711, the dividing ring 71 and the planting pot 6. A plurality of flow channels 712 are evenly provided on the annular inclined groove 711. The flow channels 712 are used to connect the annular water distribution chamber and the bottom of the permeable ring 75. A fixing ring 76 is fixedly provided on the inner wall of the planting pot 6. A first support rod 77 is fixedly provided on the lower surface of the fixing ring 76. A spring 78 is fixed to the bottom end of the first support rod 77, a second support rod 79 is fixed to the bottom end of the spring 78, and a wedge-shaped blocking plate 710 is fixed to the bottom end of the second support rod 79. The wedge-shaped blocking plate 710 is pressed and fitted into the annular inclined groove 711 on the surface of the permeable ring 75, and several wedge-shaped blocking plates 710 are evenly distributed. The number of wedge-shaped blocking plates 710 matches the number of flow channels 712. The wedge-shaped blocking plates 710 seal the opening of the flow channel 712 in the annular water distribution chamber by fitting against the annular inclined groove 711. The spring 78, the second support rod 79, and the wedge-shaped blocking plates 710 together constitute a mechanical feedback regulating valve. The spring 78 provides a downward preload, and the wedge-shaped end of the wedge-shaped blocking plate 710 is in close contact with the outer surface of the permeable ring 75. The permeable ring 75 is installed close to the inner wall of the planting pot 6 on the outside of the dividing ring 71. Its core function is to work in conjunction with the wedge-shaped blocking plate 710. When water is injected into the annular water distribution chamber, the wedge-shaped blocking plate 710 blocks the flow channel 712, thereby preventing liquid from entering the bottom space of the dividing ring 71, and then spraying the water into the soil from the nozzle 73. By setting the fixing ring 76 and the first support rod 77, an upper mounting fixing point and support structure are provided for the subsequent automatic adjustment component, the wedge-shaped blocking plate 710, ensuring its accurate positioning and stable operation.

[0029] When excess water needs to be extracted from the inner cavity of the planting pot 6, the water pump 54 generates suction, and the inside of the dividing ring 71 generates suction, which in turn moves the wedge-shaped blocking plate 710 away from the permeable ring 75, releasing the blockage of the flow channel 712. At this time, the water accumulated at the bottom of the planting pot 6 will enter the annular water distribution chamber through the flow channel 712 and finally be drawn back into the inner cavity of the water tank 1.

[0030] Working Principle: When the processor determines that irrigation is needed, it will activate the water pump 54 of the pumping mechanism 5 in forward rotation upward pumping mode. Pumping and Delivery: The water pump 54 draws water from the adapter cylinder 53. The liquid at the bottom of the water tank 1 flows into the adapter cylinder 53 to replenish the water tank 53 through the bottom gap formed by the shim block 4 and the permeable holes 52 on the wall of the shim cylinder 51. The pumped liquid flows upward through the straight pipe 55, through the transfer ring 3 and the connecting pipe 9, and finally enters the annular water distribution chamber (composed of the annular inclined groove 711, the dividing ring 71 and the planting pot 6). In this mode, the water flow increases the pressure in the water distribution chamber. Under the action of the spring force of the spring 78, the wedge-shaped blocking plate 710 is aligned with the holes on the surface of the permeable ring 75 and is tightly pressed against the surface of the annular inclined groove 711, thereby blocking the flow channel 712 when water is injected. Then the water flow pushes open the upper spray nozzle 73: the continuously injected water flow further increases the pressure inside the cavity. When the pressure exceeds the pre-tightening sealing force of the sealing ring 74, the water flow pushes up the sealing ring 74 and flows upward from the evenly distributed spray nozzles 73, directly wetting the upper and surrounding soil in the form of "seepage", achieving rapid and uniform irrigation.

[0031] Stop Irrigation: When the hygrometer 12 detects that the soil moisture has returned to the normal range, the processor commands the water pump 54 to stop working. The pressure in the water distribution chamber drops, the sealing ring 74 rebounds and closes the spray nozzle 73 to prevent soil backflow; at the same time, the spring 78 returns to its original position, causing the wedge-shaped blocking plate 710 to slightly return to its original position, but the system is in standby mode.

[0032] When the soil becomes too wet due to over-irrigation or rainwater, the processor initiates a drainage program, commanding water pump 54 to reverse and pump downwards. Water pump 54 reverses, generating negative pressure suction in the water distribution chamber of the straight pipe 55, connecting pipe 9, and regulating mechanism 7. This suction acts on the wedge-shaped blocking plate 710, causing it to overcome the weight of the water and slight resistance, separating it from the annular inclined groove 711, thereby opening the flow channel 712. Excess water accumulated at the bottom of the planting pot 6 due to over-wetting is drawn into the water distribution chamber through the holes on the surface of the permeable ring 72 under gravity, and then pumped back into the water tank 1 by water pump 54 along the connecting pipe 9 and straight pipe 55. This process effectively reduces the moisture content of the soil in the root zone, preventing root rot. When the hygrometer 12 detects that the soil moisture has dropped to the normal range, the processor commands water pump 54 to stop, ending the drainage process.
