First, it easily leads to water waste, as the irrigation system may activate even when soil moisture is sufficient or during rainfall, resulting in unnecessary over-irrigation. Second, this method cannot achieve precise water supply; misjudgment or mechanical execution often leads to uneven irrigation, either insufficient watering causing drought stress and stunted growth, or over-irrigation leading to waterlogging, root hypoxia, and even root rot. Finally, whether for large-scale farmland or numerous greenhouses and potted plants, manual inspection and operation consume significant time and labor, resulting in high production costs and low management efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This irrigation device with automatic irrigation function consists of a humidity sensor, a controller, a booster pump, a submersible pump, and a buoyancy switch. The humidity sensor is buried in the soil to monitor moisture. When the data is lower than a preset value, the controller starts the booster pump, which delivers water from the storage tank to the crops through the pipeline network. The buoyancy switch monitors the water level in the tank through a float-linked limit switch. When the water level is low, the submersible pump automatically starts to replenish water and protect the booster pump; when the water level is high, water replenishment stops. This system achieves precise irrigation on demand, which not only effectively saves water resources and avoids human error, but also promotes healthy crop growth by maintaining suitable soil moisture, while reducing labor costs and improving irrigation efficiency and the level of intelligence in agricultural production.

[0013] 2. This irrigation device with automatic irrigation function consists of an extension pipe connector, a movable disc, a fixed disc, a sliding rod, a sealing plug, and a return spring. When the extension pipe connector is screwed into the connecting pipe, its end pushes the movable disc to compress the return spring. The sliding rod then moves the sealing plug backward, opening the flow channel and allowing water to enter the extension pipe through the water holes of the fixed disc and the movable disc. During disassembly, the connector is unscrewed, and the return spring pushes the movable disc and the sealing plug back to their original positions, automatically cutting off the water flow. This allows for quick connection and disconnection of the irrigation pipeline, enabling the system to flexibly adjust the position and number of water outlets, easily adapting to the diverse row spacing requirements of different crops.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an irrigation device with automatic irrigation function, which mainly includes a water supply unit, a water distribution unit, a soil monitoring unit and an intelligent control unit.

[0020] The water supply unit consists of a submersible pump 1, a water storage tank 2, and a buoyancy switch. The submersible pump 1 is installed inside the well, with its outlet connected to the inlet at the top of the water storage tank 2. A booster pump 3 is fixedly installed at the bottom of the side wall of the water storage tank 2, with its pumping end connected to the outlet at the bottom of the water storage tank 2. The buoyancy switch consists of a slide rail 11, a float 12, and a limit switch 13. The slide rail 11 is fixed to the inner wall of the water storage tank 2, and a slider 14 connected to the float 12 is slidably installed inside it. Limit switches 13 are provided on both the upper and lower sides of the slide rail 11, and the slider 14 can abut against the limit switches 13. This automatically maintains a stable water level in the water storage tank 2, preventing the pump from running dry and ensuring a continuous and reliable water supply.

[0021] The water distribution unit includes a main pipe 4, branch pipes 5, connecting pipes 6, and quick-connect components. The outlet of the booster pump 3 is connected to the main pipe 4. Multiple branch pipes 5 are provided on both sides of the main pipe 4, and each branch pipe 5 is connected to a connecting pipe 6 with an internal quick-connect component. The quick-connect component consists of a fixed plate 15, a movable plate 16, and a sealing plug 17. The fixed plate 15 is fixed inside the connecting pipe 6, and the movable plate 16 is slidable. Both have radial water passage holes. One end of the slide rod 18 is fixed to the movable plate 16, and the other end is connected to the sealing plug 17. A return spring 19 is sleeved on the outside of the slide rod 18, and its two ends are connected to the fixed plate 15 and the movable plate 16, respectively. The end of the connecting pipe 6 has a screw hole 20, which can be threaded to the extension pipe connector 7. This design facilitates quick connection to irrigation pipelines and allows for flexible adjustment of the outlet position to adapt to different crop spacing.

[0022] The soil monitoring unit consists of a rotating rod 8, snap-fit ​​rings 9, and a humidity sensor 10. The rotating rod 8 is rotatably mounted on the upper end of the main pipe 4 at the position corresponding to the branch pipe 5, and multiple snap-fit ​​rings 9 are evenly spaced on it for snapping and fixing the humidity sensor 10. This structure allows the humidity sensor 10 to be flexibly arranged within the rotation radius, ensuring accurate monitoring of soil moisture at different locations.

[0023] The core of the control unit is the controller 21. The submersible pump 1, booster pump 3, humidity sensor 10, and limit switch 13 are all electrically connected to the controller 21. The limit switch 13 of the buoyancy switch is wired to a relay in the controller 21, which directly controls the power supply circuit of the submersible pump 1. Irrigation can be automatically started and stopped according to soil moisture, and water supply can be controlled in conjunction with the buoyancy switch, achieving intelligent and precise irrigation.

[0024] In addition, a top cover 22 is snapped onto the top of the water storage tank 2, and drainage holes are evenly spaced on the top cover. This prevents debris from entering the water tank and facilitates the collection of rainwater into the water storage tank 2.

[0025] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0026] Working principle: The automatic irrigation system operates on the principle of intelligent control linked to soil moisture monitoring and water tank level. During irrigation, the user can manually rotate the rotating rod 8. The rod 8 rotates horizontally with its connection point to the main pipe 4 as the axis and its body as the radius, thus precisely positioning the humidity sensor 10, fixed to its locking ring 9, to any monitoring point within the irrigation area. Each humidity sensor 10, after being fixed by vertical insertion into the locking ring 9, has its detection end buried 10-15 cm deep in the soil, and its signal line is connected to the controller 21. When the sensor detects that the soil moisture is lower than the preset threshold of the controller 21, the controller 21 immediately starts the booster pump 3. The booster pump 3 draws water from the water storage tank 2, and the water flows sequentially through the main pipe 4, branch pipe 5, connecting pipe 6, and finally through the extension pipe connector 7 to the extension pipe to complete the irrigation operation.

[0027] Water supply is automatically regulated by a buoyancy switch. When the water level in the storage tank 2 drops to the set lower limit, the float 12 descends with the water level, driving the rigidly connected slider 14 to move down along the slide rail 11 until it triggers the bottom limit switch 13. After this trigger signal is transmitted to the controller 21, the system disconnects the power supply circuit of the booster pump 3 via a relay to effectively prevent it from running dry; on the other hand, it immediately starts the submersible pump 1 to replenish water to the storage tank 2 from the well. Conversely, when the water level rises to the set upper limit, the float 12 drives the slider 14 to move up and triggers the top limit switch 13. The controller 21 then commands the submersible pump 1 to stop working and restores the power supply circuit of the booster pump 3 to put it in standby mode, thereby ensuring that the booster pump 3 can start normally when the irrigation command is issued.

[0028] When installing the extension pipe connector 7, screw its threaded end into the threaded hole 20 of the connecting pipe 6. During the screwing process, the end face of the extension pipe connector 7 pushes the movable disk 16 towards the fixed disk 15, thereby causing the sliding rod 18 to move the sealing plug 17 out of its sealed position in the connecting pipe 6 and into the cavity of the branch pipe 5, while simultaneously compressing the return spring 19. When the radial water passage hole on the fixed disk 15 aligns with that on the movable disk 16, the channel between the connecting pipe 6 and the branch pipe 5 is opened, and water can flow into the extension pipe connector 7 through the aligned water passage hole. During disassembly, unscrew the extension pipe connector 7 in the opposite direction. The return spring 19 returns to its original shape, pushing the movable disk 16, sliding rod 18, and sealing plug 17 back to their original positions. The sealing plug 17 then re-closes the channel of the connecting pipe 6, effectively preventing water leakage. This allows the system to quickly adapt to the planting spacing requirements of different crops.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
